Description
Technical field
Different forms of implementation relates to for automatically handling the technology of the closing element (Schliesselement) of motor vehicle.Different forms of implementation relates in particular to such technology, and it is identified in stopping of object in first peripheral region (Umfeldbereich) of motor vehicle.
Background technology
According to the known the method for prior art, utilize it for example can by the motion of leg, open the door of motor vehicle, for example, referring to file DE 10 2,009 017 404 A1, file DE 10 2,006 044 112 A1, file DE 10 2,004 055 982 A1 or file DE 101 06 400 B4.
When opening and closing the Men Hegai (Klappe) of closing element, for example motor vehicle with sensor, often assess motion or the posture of object (for example hand or pin).When the motion detecting by means of sensor of corresponding object or the evaluated algorithm evaluation of posture be favourable, during for example corresponding to the default motion model in the margin of tolerance or trigger criteria (Ausl sekriterium), according to prior art, so typically just handle closing element.Such fortune dynamic posture for example can comprise across appearance or play appearance or brandish posture (for example using hand).If it is favourable that corresponding motion is not assessed as, do not handle corresponding door or lid, even if this motion is implemented by the personnel that have the right for vehicle.The checking of personnel's right for example can realize by means of for example discriminating transmitter (Identifikationsgeber) with the form of car key.Abstractively, corresponding technology can be at the manipulation of enough sensitivities and the moving in the nervous district (Spannungsfeld) between wrong avoiding of handling unintentionally of closing element of closing element, i.e. firm system.If emphasize one or more points of observation, user's comfortableness reduces.
Due to restricted sensitiveness and/or wrong the avoiding of handling of used sensor, it can be necessary near closing element, carrying out this motion especially.Therefore can occur, personnel are positioned at the wobble area of closing element.Can not avoid corresponding potential danger completely thus.Can reduce user's comfortableness thus.
In addition, the execution of motion can be only possible for the most different personnel limitedly; For example the personnel for the physical limitation with to a certain degree can not or only may carry out the most different motions limitedly.The corresponding motion of study or posture can be also relatively difficult.Often can need according to handbook study motion or posture.By user's instinct, being handled may be difficult thus.This also can reduce user's comfortableness.
Therefore there is the demand to the improved technology of the closing element for automatic manipulation motor vehicle.Especially have the demand to such technology, it allows to reliably and identifies simply and stably user's manipulation hope and it has larger user's comfortableness.
Summary of the invention
This object is realized by the feature of independent claims.Preferred form of implementation is described in dependent claims.
According on the one hand, the present invention relates to a kind ofly for handling the method for the closing element of motor vehicle, wherein, the method comprises that recognition object enters in the first peripheral region of motor vehicle and recognition object leaves the first peripheral region.In addition, the method comprises that recognition object stopped in the first peripheral region in the default time period.In addition, the method comprise according to object identify enter and/or identify leave and/or identify stop optionally checking existence and the distinctive of differentiating transmitter in the second week region of motor vehicle.The method comprises in addition according to differentiating that in second week region the existence checking of transmitter and distinctive optionally handle closing element.
For example, closing element can be the door of motor vehicle or luggage-boot lid or other lid of motor vehicle.Object for example can comprise user's shank and foot.
In other words, the identification that enters and leave or stop of object and the random inspection of existence can define trigger criteria to the automatic manipulation of closing element.Handle and for example can represent open and/or closed closing element.To this, can be provided with motor and/or for example with the flexible member of constraint mechanism (Rueckhaltemechanismus).In other words trigger criteria can not only comprise certain sequence of motion but also comprise object stopping in the first peripheral region.Additionally also can consider by differentiating the checking (Authentifizierung) of transmitter.Unidentifiedly if identified stopping of Preset Time go out to leave, so for example only can carry out optionally and check.
Differentiate that transmitter can be for example the key of motor vehicle.Differentiate that transmitter for example can comprise receiver and transmitter, it allows to be connected with motor vehicle radio.By from and/or can carry out the discriminating of differentiating transmitter second week region to motor vehicle transmission authentication information.In addition for known its of professional person, allow to be identified in the technology of differentiating the existence of transmitter in second week region.This can comprise determines the position of differentiating transmitter.Such technology for example can comprise that the different transmitters in motor vehicle send electromagnetic field with certain frequency, and it can be measured by the receiver in discriminating transmitter.For example according to the field intensity of the electromagnetic field of corresponding transmitting, can come like this to determine to differentiate in region around the position of transmitter and its existence (this can the distance based on with transmitter increase field strength attenuation) thus.Become known for determining the alternative technique of the existence of differentiating transmitter, thereby above-mentioned example is as restrictively designing.
Because recognizable object stopping in the first peripheral region, for example can realize for user, treat to implement more simply for automated trigger criteria.For example possibility recognition object, i.e. for example user's shank and foot static the standing (stance) in the first peripheral region.The consideration stopping of object can have advantages of the simple learnability by user, that is to say and can learn by the light of nature.In addition, the personnel for the physical limitation with to a certain degree also may be by stopping meeting trigger criteria.Especially relatively known by prior art and for example comprise the solution of the identification of playing appearance, this can mean the obviously simpler trigger criteria of object.
Likely, the sensing data of capacitance sensor is considered in the identification entering and the identification of leaving.Alternatively or additionally likely, the sensing data of optical pickocff is considered in the identification stopping of object.
Can be for example likely, the operation of the operating ratio optical pickocff of capacitance sensor causes energy requirement relatively still less.Therefore the identification stopping of optionally carrying out object by means of optical pickocff can be possible, that is so like this when coming recognition object to enter in the first peripheral region by capacitance sensor.If capacitance sensor and/or optical pickocff identify object and leave the first peripheral region in addition, interrupt so the identification stopping of object.In other words, the identification that enters, leaves and stop can hierarchically or crosslinkedly realizing.So graduate or crosslinked assessment by sensor can realize for for automatically handling the energy consumption that the method for closing element reduces (this for the motor vehicle of the accumulator with limited, the application of for example electric motor car can mean particularly advantageous effect).Certainly, other of different sensors type and different step is associated is possible according to current discussed aspect.
Also possible that, in the first peripheral region the identification stopping of object and/or in second week region, differentiate the existence of transmitter and distinctive random inspection by means of for differentiating that the navigation system of transmitter occurs, navigation system be used in a plurality of rotations in position of differentiating transmitter electromagnetic field differ (Differenzphase) for differentiating the location positioning of transmitter.
The electromagnetic field of a plurality of rotations for example can be issued by the coil block with a plurality of coils, and coil is arranged in the diverse location place in motor vehicle.By a plurality of coils with alternating voltage supply coil assembly (it has certain phase relation), can be similar to the electromagnetic field that three phase alternating current motor produces rotation.The em field of a plurality of rotations can be measured by the receiver in discriminating transmitter.Receiver for example can comprise coil.
Electromagnetism (em) field for example can be called as the em field of rotation, because amplitude, be that field intensity can be rotated around transmitter according to the time, can in Plane of rotation, carry out and rotatablely move.In other words, the maximum value of the amplitude of em field or minimum value for example can be according to corresponding being arranged in respect under the different direction of transmitter of time.The point of identical phase place can rotate around transmitter.Say visually, amplitude can move as the light beam of beacon (at this transmitter).In particular, the speed rotatablely moving can equal the frequency of em field itself.Plane of rotation can be parallel with the coil plane of a plurality of coils of coil block.For example, the Plane of rotation of a plurality of coil blocks can be almost parallel.
For example, the em field of a plurality of rotations produces serially or with different frequencies.For the em field of a plurality of rotations, can correspondingly determine and differ (for example with respect to reference to phase (Referenzphase)).With reference to for example transmitting by means of beat information mutually, it is modulated onto on em field.Location positioning for example can comprise and comes from the triangulation survey that a plurality of differences differ.
By means of such technology, differentiate that transmitter accurate especially location positioning in second week region and/or the first peripheral region can be for example possible.The precision of location positioning for example can be several centimetres.Therefore, alternative in or be additional to the form of implementation of considering sensor optics and/or electric capacity by means of can be possible for differentiating that the navigation system of transmitter is carried out the identification stopping of object.
Likely, from object identify enter another default time period in carry out the identification of leaving of object, preferably another default time period for this time period of presetting for about 3 seconds be about 2 seconds.
For example, along with identifying object, enter the first peripheral region and start to check object stopping in Preset Time section.To this, can start timer while entering identifying.In other words, when identifying object and enter in the first peripheral region, can check or the stopping of recognition object, until identify object leave or identify in the default time period, for example, within 2 seconds, continue to stop or the default other time period finishes, for example, after 3 seconds.If identify stopping in these standards, next for example can realize existence and the distinctive inspection of differentiating transmitter in second week region.If identified in second week region, differentiate transmitter and realize sure checking, can handle closing element.
For example, the default other time period can be 3 ± 2 seconds, preferably 3 ± 1 seconds, particularly preferably 3 ± 0.2 seconds.For example, this default time period can be 2 ± 1 seconds, preferably 2 ± 0.2 seconds.
For example likely, the first and second peripheral regions in the mode that is contiguous to closing element place, from the outside of motor vehicle, extend and the first and second peripheral regions in the left side of closing element and/or extend from the outside of motor vehicle on right side and the first and second peripheral regions at least in part overlapping and second week region than the first peripheral region, from the outside of motor vehicle, extend to larger distance.
For example, peripheral region can be arranged in closing element around.By on position near between peripheral region and closing element, it can be possible controlling pointedly automatically controlling of certain closing element.Can reduce like this possibility of the mistake manipulation of closing element.Especially the restriction (for example comparing with the size of second week region) of the size by the first peripheral region, the situation that the mistake of closing element is handled can become more impossible.
Especially can be likely, the first peripheral region and/or second week region extend at least in part outside the wobble area of closing element.
The wobble area of closing element for example can represent the radius of opening of door or luggage-boot lid.By such form of implementation, for example can avoid object or user must stay within the wobble area of closing element to trigger the automatic manipulation of closing element.So for example can improve the operating reliability in the method for automatic manipulation closing element.
The method can comprise that the time above entered in the 3rd peripheral region of motor vehicle by means of sensor recognition object electric capacity and/or optics before recognition object enters the first peripheral region in addition, wherein, the 3rd peripheral region can extend from the outside different with second week region from the first peripheral region of motor vehicle.
For example, the 3rd peripheral region can relative the first peripheral region and/or second week region separately.For example, the 3rd peripheral region can be contiguous to another closing element place of motor vehicle, is for example contiguous to another door or luggage-boot lid place.For example, can realize and enter the identification in the 3rd peripheral region by means of sensor electric capacity and/or optics.At this, can relate to other sensor, but it for example can be identical with the sensor general configuration that monitors the first and second peripheral regions.
Like this, if identify in advance object, enter the 3rd peripheral region, the activation of so optionally carrying out capacitance sensor and/or optical pickocff and/or navigation system enters the first peripheral region or leaves the first peripheral region or stopping in the first peripheral region can be for example possible with recognition object with identification with recognition object.When facing wrong manipulation, corresponding also may carry out capacitance sensor and/or optical pickocff and/or navigation system its optionally remove activation.In other words, if detect in advance object in the 3rd peripheral region, so just can realize sensing device about first and/or the optionally accurate adjustment (Scharfstellung) of second week region.
Such form of implementation can have the effect of the mistake manipulation of the closing element that reduces electric current demand and/or avoid motor vehicle, briefly setting forth as come below.For example, the certain motion model about the 3rd peripheral region and first/second week region identification user can be possible.Such motion model for example can comprise user at motor vehicle place from driver door towards luggage-boot lid along advancing.Alternatively, by the 3rd peripheral region, from the side door of motor vehicle, start extension and identify the third party who has neither part nor lot in (to that is to say such personnel, it does not have discriminating transmitter) process, it will be also for example possible that explorer motor-car is parked in the area (Gegend) of extremely frequently being used by pedestrian.For example can carry out object with less repetitive rate in such a case and enter the identification in the first peripheral region.
As a rule, can exist and for identifying, enter, leave and crosslinked at the sensor stopping of the first peripheral region and other sensor.
Also possible that, the method comprises upper existence and the distinctive of differentiating transmitter in 4th week region that checked before recognition object enters the first peripheral region of time in addition, wherein, 4th week region extends to larger distance than the first peripheral region and second week region from the outside of motor vehicle around motor vehicle.
For example, 4th week region can extend upward all sides around motor vehicle substantially.For example likely, 4th week region has circle or ellipse, and it has the center at close motor vehicle center.4th week region for example can be fully or is partly surrounded the first peripheral region and/or second week region and/or the 3rd peripheral region.4th week region can represent motor vehicle territory, far field around, and first, second, and third peripheral region can represent motor vehicle near field around.
Can be for example worthwhile, to check differentiate the existence of transmitter in second week region than checking that the larger repetitive rate of existence differentiate transmitter in 4th week region is carried out.In other words, detect and in 4th week region, to differentiate that the existence of transmitter can approach motor vehicle and therefore fewer execution corresponding to detecting object.In 4th week region approach detection therefore can be called as differentiate transmitter " examination (pingen) ", that is to say with certain repetitive rate and send framing signal.
Likely, utilize the first positioning precision and the first energy consumption to carry out existence and the distinctive inspection of differentiating transmitter in second week region, and utilize the second positioning precision and the second energy consumption to carry out existence and the distinctive inspection of differentiating transmitter in 4th week region.Also possible that, the first positioning precision is more accurate than the second positioning precision, and the first energy consumption is greater than the second energy consumption.
For example,, for differentiating that the navigation system of transmitter can provide the first and second positioning precisions in the scope of the first and second operational modes.For example, the first operational mode can comprise the definite or triangulation survey of sending and differing of the em field of a plurality of rotations; With the second operational mode of relatively less positioning precision, can comprise the measurement with the amplitude of the magnetic-field component of em field of sending of single (for example irrotational) em field.If also determine from amplitude with relatively less positioning precision and differentiate that transmitter to the distance of motor vehicle can be possible.
Likely, existence and the distinctive inspection of in 4th week region, differentiating transmitter occur and according to the existence of differentiating transmitter in 4th week region and the distinctive that are checked, carry out the identification that object enters into the first peripheral region, the identification of leaving and the identification stopping with the repetition rate of being scheduled to.
If for example identified, differentiate that transmitter approaches motor vehicle, next optionally carry out ensuing method step, especially object enters the identification in the first peripheral region.So for example can reduce for carrying out for automatically handling the energy consumption of the method for closing element.With it, check that the predetermined repetition rate of the existence of differentiating transmitter in 4th week region especially can be less than and in second week region, differentiate the existence of transmitter and the repetition rate that distinctive random inspection is occurred.
Aforementioned form of implementation is shown conventionally, can realizes therein the most different sensors crosslinked of the peripheral region of monitoring machine motor-car.This is crosslinked for example can be attached to the bus system place of motor vehicle and realize via different sensors.What control device can be controlled different sensors via control command according to the sensing data of other sensor controls, activates, removes activation etc.Sensor can be connected with control device by means of bus system.In sensor, can be reserved with unit calculator in addition, its activation/releasing of optionally carrying out sensor according to the control signal sending via vehicle bus system activates.Thus, it can be for example possible reducing energy consumption and avoid wrong manipulation.
The method comprises in addition by means of at least mistake the facing manipulation of another sensor identification closing element, wherein, in the situation that identifies the mistake manipulation facing, does not carry out and differentiate the existence of transmitter and the random inspection of identity and selectively handle.
For example, the identification that the mistake that faces is handled comprises the factor of following group: the water wave identification (Schwallwassererkennung) at another capacitance sensor place in the side door at motor vehicle preferably; Utilize preferably other sensor electric capacity and/or optics of at least two in the side door of motor vehicle to identify (Passantenerkennung) to the third party's of process pedestrian.
For example, this at least one other sensor can be other optical pickocff and/or other capacitance sensor.For example especially likely, optical pickocff and/or capacitance sensor and/or navigation system and this at least one other sensor are connected with control device by means of bus system.
For example, the identification of water wave can comprise, other capacitance sensor (it is for example arranged on the side door place of motor vehicle) identification is the wave of the water in the scope of carwash and cause that temporary transient interruption execution object enters the method step of the identification stopping of the identification in the first peripheral region, the identification of leaving the first peripheral region and object in washing track (Waschstrasse) for example.In to the scope of pedestrian's identification of the third party of process (for example such people, it does not occupy differentiates transmitter), for example, can realize by sensors at least two other electric capacity and/or optics the frequent detection of signal.Can realize again in such a case that temporary transient interruption identification enters or leave the first peripheral region and recognition object stops in the first peripheral region.Alternatively, when identifying pedestrian around, the repetition rate that reduces the object to enter the identification in the first peripheral region can be possible.Such technology of controlling by crosslinked sensor, except reducing the possibility that the mistake of the closing element of motor vehicle handles, it can be possible realizing for carrying out for automatically handling the less energy consumption of the method for closing element.
Utilize above-mentioned feature can obtain multiple effect: the first, can realize automatically handling reliably of closing element, because can be likely, the first and second peripheral regions extend beyond the wobble area of closing element.For example will be likely in such situation, identify just stopping outside wobble area of object.Will be likely, user is to be contiguous to the mode at wobble area place and to stop in the first peripheral region and this identification stopping causes automatically handling closing element.The second, can realize for carrying out the effect for the less energy absorption of automated method.Before mention the most different standards, it can cause, according to such activation Standard Selection carry out that recognition object enters and leave the first peripheral region or object stops in the first peripheral region.For example crosslinked with the other sensor of supervision the 3rd or 4th week region by respective sensor, can realize and optionally activate the sensor that enters and leave or stop for identifying.Can reduce energy consumption thus.The 3rd, can realize the effect of the wrong possibility still less of handling, for example, because also can identify the situation that the mistake facing is handled the pedestrian of water wave or process (due to) according to other sensor.May prophylactically remove in such a case to activate for identifying and enter and leave or at the corresponding sensor stopping of the first peripheral region.The 4th, study can be possible for handling the trigger criteria of closing element by the light of nature.Especially can learn maybe can carry out stance simply and uncomplicatedly.
By means of crosslinked sensing device (identification of its posture based on user and differentiate transmitter or the location positioning of key) and in the situation that consider that the mistake facing handles the automated instinct of the closing element that can realize motor vehicle and control.Different closing elements can be controlled the easier load or unload of motor vehicle.Deathtrap when open and/or closed closing element can be restricted, since the layout at motor vehicle place according to different sensors for example, the extended wobble area that surpasses corresponding closing element in peripheral region.For example can provide by by means of posture, especially the control of stance opens or closes the possibility of closing element to user thus, and this not in closing element close or wobble area in.In addition, the search coverage of user's posture is by differentiating that (ausfallen) can more stably obtain a result in the location more accurately of transmitter or key.Can avoid or reduce situation about handling as the mistake of pedestrian's process.Generally speaking, can realize in operation higher user's friendliness.
According on the other hand, the present invention relates to a kind of device for automatic manipulation closing element, wherein, this device is set up to execution following steps: recognition object enters in the first peripheral region of motor vehicle; Recognition object leaves the first peripheral region; Recognition object stopped in the first peripheral region in the default time period.This device comprises in addition for differentiating the navigation system of transmitter, its be set up to according to object identify enter and/or identify leave and/or identify stop checking existence and the distinctive of differentiating transmitter in the second week region of motor vehicle.This device comprises manipulation device in addition, and it is set up to according to differentiating that in second week region the existence being checked of transmitter and distinctive optionally handle closing element.
This device can be designed to carry out the method for automatic manipulation closing element according to a further aspect in the invention.
For such device can obtain with for according to a further aspect in the invention for automatically handling the comparable effect of the obtainable effect of method of closing element.
Certainly, the feature of aforesaid form of implementation of the present invention and aspect can combine mutually.In particular, these features not only can but also can or be used with other combination individually with illustrated combination, and do not leave scope of the present invention.

The specific embodiment
Fig. 1 shows the schematic view of the device 100a of the closing element 3a-3e (for example door or luggage-boot lid or sliding door) for automatically handling motor vehicle.For example, for corresponding capacitance sensor 20 and the optical pickocff 21 of providing of five closing element 3a-3e (two Qianmens, two back doors, a luggage-boot lid) altogether.It for example can be integrated in closing element or be arranged on closing element around.Object in detectable the first peripheral region at motor vehicle of sensor 20,21 (it is contiguous to corresponding closing element 3a-3e place).The form of object or type can be for example arbitrarily.So being only in or be not in of (arbitrarily) object can be conclusive.But also can carry out object identification, thereby object form is conclusive.According to the orientation of sensor 20,21, object can be preferably user's foot or leg area.
Be provided for differentiating the navigation system 100 of transmitter 30.Differentiate that transmitter 30 can be for example the wireless key for motor vehicle.Navigation system 100 can be determined the position of differentiating transmitter 30.To this, navigation system for example can be sent electromagnetism (em) with certain frequency, and for example, via coil or coil block, it utilizes alternating voltage to control.Especially also may send the em field of rotation.Discriminating transmitter 30 can be measured these, for example, utilize receiving coil; In this this measurement, for example can allow to determine em field magnetic-field component amplitude and/or the em field of rotation is determined with respect to for example, differing with reference to the phase beat information transmission of modulation (via).In the first operational mode of navigation system 100, the em field of definite rotation differs and carries out definite triangulation survey differing for the location positioning of receiver 30.In the second operational mode, measure the amplitude of the em field not rotating and come thus executing location to determine.According to used technology, can in location positioning, obtain different position resolution (Ortsaufloesung).Radio port 31 can be set up with the wireless data of differentiating transmitter 30 and be connected (dotted line in Fig. 1).The discriminating that for example can transmit discriminating transmitter 30 and/or motor vehicle via data connection is for checking.Also may in differentiating transmitter 30, fully or partly determine and differentiate the position of transmitter 30 and transmit corresponding information via radio port 31.
As seen from Figure 1, different sensor 20,21 and navigation systems 100 is cross-linked with each other.Next come elaboration technology and trigger criteria, the sensing data according to it based on sensor 20,21 and navigation system 100 can be carried out the manipulation of in closing element 3a-3e.Manipulation can represent not only opening but also closing of corresponding closing element 3a-3e at this.To this, for example, can be reserved with flexible member and/or operated motor (Betaetigungsmotor) (not shown in Fig. 1) in the mode mechanically connecting mutually with corresponding closing element 3a-3e.Corresponding known for professional for the technology of handling.
Such trigger criteria for example can define about the peripheral region of motor vehicle, as next it discuss with reference to figure 2.Fig. 2 is the top view to motor vehicle 1.Motor vehicle 1 has positive 2a, left-external side 2b, right outside side 2c and back side 2d.At left-external side 2b place, be furnished with left front door 3a and left back door 3c; At right outside side 2c place, be furnished with right front door 3b and right-rear-door 3d.2d place is furnished with luggage-boot lid 3e overleaf.In the form of implementation of Fig. 2, in motor vehicle 1, build altogether four capacitance sensors 20 and four optical pickocffs 21 (conventionally can use sensor more or still less).At this, in B post left side and right side of motor vehicle 1, be built with respectively optical pickocff 21 and capacitance sensor 20,21.In addition, in bumper bar in the wings, that is to say and at 2d place, the back side of motor vehicle 1, be built with respectively sensor 20,21 optics and electric capacity.
Electric capacity and optical pickocff 20,21 are arranged so that the existence of its detectable surrounding at motor vehicle (for example arbitrary objects). Sensor 20,21 is especially set up to and makes it can identify entering of object and leave and stopping in the first peripheral region 11.
The first peripheral region 11 corresponding corresponding outside 2b, 2c from motor vehicle 1 and 2d stretch out from sensor 20,21.In the form of implementation of Fig. 2, the first peripheral region 11 is approximately semicircle, and it is with for example in 10-50cm, the about radius in the scope of 20cm preferably.As can be seen from Fig. 2, the first peripheral region 11 can be positioned at outside the wobble area of corresponding closing element 3a, 3b, 3e at least in part.
In this external Fig. 2, draw the second week region 12 (utilizing dotted line in Fig. 2) for each of sensor 20,21 used optics and electric capacity.The first peripheral region 11 arranges near the corresponding outside 2b of motor vehicle 1,2c, 2d especially, and second week region 12 extends to outside 2b, 2c, the 2d of motor vehicle 1 and becomes larger spacing.Second week region 12 comprises the first peripheral region 11.
In Fig. 2, show in addition the 3rd peripheral region 13, it overlaps with the first peripheral region 11 of the side door 3a left side and the right, 3b.In Fig. 2, draw in addition 4th week region 14, it has about circle, and it is with the center near solving the center of motor vehicle 1.4th week region 14 but not limited especially.4th week region 14 is especially compared with the larger spacing extension in the outside with motor vehicle 2a-2d and is therefore hidden motor vehicle territory, far field around with the first and second peripheral regions 11,12.4th week region 14 comprises other peripheral region 11,12,13.
Navigation system 100 (not shown in Fig. 2) be set up in case differentiate transmitter 30 enter 4th week region 14 in time identify and differentiate that transmitter 30 approaches motor vehicle 1.To this, navigation system 100 can be sent electromagnetic field with certain repetition rate, and it can be by receiver 30 be measured in entering 4th week region 14 time.Receiver 30 then can be by means of radio port 31 notices, and it has entered 4th week region 14.
For the size of the first and second peripheral regions 11,12 of sensor 20,21 (the automatic manipulation that it is arranged in the 2d place, the back side of motor vehicle 1 and therefore controls luggage-boot lid 3e) be arranged in Fig. 3 and be shown specifically.Fig. 3 is the rear view of the situation in Fig. 2.As seen from Figure 3, the first and second peripheral regions 11,12 also can be of different sizes on the vertical direction perpendicular to ground.Second week region 12 for example may extend to respect to ground the vertical spacing larger than second week region 12. Other sensor 20,21 at side door 3a, 3b place also can have corresponding feature.
It should be understood that pure electric capacity and the layout of optical pickocff 20,21 and layout, form and the size of peripheral region 11-14 being illustrated in illustratively and without limitation in motor vehicle 1 in Fig. 2 and 3.In particular, can be for example possible with the infield of sensor 20,21 in motor vehicle 1 of differently selecting shown in Fig. 2 and Fig. 3.This example is provided in Fig. 5 A-5C.In Fig. 5 A sensor 20,21 be arranged in the surrounding of corresponding closing element 3a, in the B of motor vehicle 1 post.In Fig. 5 C, sensor 20,21 is integrated in closing element 3e.The corresponding adjusting of the sensitive range by sensor 20,21, it can be also possible alternatively or additionally differently selecting the size of peripheral region 11,12 and direction.In addition certainly may provide more or less sensor 20,21 (referring to for example Fig. 5 B, be provided with therein two optical pickocffs and capacitance sensor 20,21, and Fig. 5 C, be only provided with therein an optical pickocff and capacitance sensor 20,21).For example, for back door 3c, the 3d of motor vehicle 1 provides additional independent sensor 20,21, can be also possible.It can be also possible in the region of the rear side 2d of motor vehicle 1, providing other sensor 20,21.Also may be for example in the region of the rear side 2d of motor vehicle 1, the first and second peripheral regions 11,12 be designed to it hides in motor vehicle 1 whole peripheral region below, replaces as shown in FIG. 2 only on left side and right side.
The lateral view that shows motor vehicle 1 in Fig. 6.The first peripheral region 11 and the second week region 12 of luggage-boot lid 3e illustrate about user 401.User 401 shank and foot 400 are identified objects in the first peripheral region 11 at this.User 401 is positioned at outside the wobble area of luggage-boot lid 3e.Fig. 6 shows user 401 stance.User 401 for example can keep at least 2 seconds in this position thus, and this causes luggage-boot lid 3e to open.
As visible from the above description, device 100a has larger variability at aspects such as the quantity of sensor 20,21,100, layout, types.Such architectural characteristic is discussed above, and is next set forth in more detail automated trigger criteria.
With reference to figure 4, next illustrate for automatically handling the method for the closing element of motor vehicle 1.Exemplarily, about luggage-boot lid, 3e discusses the method, but certainly also may apply corresponding technology about door 3a-3d.
The method starts with step S1.First in step S2, at 4th week region 14, find in the territory, far field around motor vehicle 1 and differentiate transmitter or key 30.To this, navigation system 100 is sent the amplitude of the magnetic component of em field and key 30 measurement em fields with certain default repetitive rate.Can determine the field intensity of em field thus.The distance of the transmitter of itself and key 30 to em fields is proportional.Then can check that key 30 is whether near motor vehicle 1, be positioned at 4th week region 14.The searching of such repetition of key 30 also can be called as " examination " of key.
The precision (positioning precision) of determining the position of key 30 can be smaller.For example, for the positioning precision of location positioning via field intensity inherently with wrong, for example, due to the inhomogeneities of the attenuation rate of the em field of the surrounding at motor vehicle 1.The measurement of amplitude also can have larger unreliability or mistake.Yet the location of the type or location positioning consume less energy.Because repeat the examination of key in the inactive state of motor vehicle 1, can significantly reduce energy consumption like this.
Step S2 especially can comprise via radio interface 31 from and/or to key 30 transmission authentication informations.For example, if detect around strange key 30 (belonging to another motor vehicle) in region 14, check at this and whether relate to for motor vehicle 1 key (step S3) that authorize or that have the right.To this, the discriminating of key can be compared with the discriminating of motor vehicle 1.
If find correct key in step S3, perform step S4 in 4th week region 14.In step S4, realize the activation of all capacitance sensors 20.The activation of sensor 20 can mean at this: recognition object 400 enters in the first and the 3rd peripheral region 11,13 (step S5).About luggage-boot lid 3e (its this as above observe with setting forth) this especially means: recognition object 400 enters in the first peripheral region 11.In other words, carry out accurate adjustment, for example with energy, supply capacitance sensor 20.
Step S2, S3, S4 are optional steps.It can be also possible abandoning in 4th week region 14 finding key 30 and replace in principle capacitance sensor 20 being remained on to state of activation.
In step S5, whether rechecking object 400 enters the first peripheral region 11.For example, user 401 can be near the luggage-boot lid 3e of motor vehicle 1.Once user 401 enough near-earth, near luggage-boot lid 3e, can identify by means of the capacitance sensor 20 activating during this period, user 401 foot and shank 400 (referring to Fig. 6) are positioned at the first peripheral region 11.In other words, recognizable object 400, in the first peripheral region 11 that this user's pin or leg enters motor vehicle 1.
Then in step S6, realize the activation of optical pickocff 21, it monitors the first peripheral region 11.This is mounted in the optical pickocff 21 at the dorsal part 2d place of motor vehicle 1 in the form of implementation of Fig. 2.Typically, the power consumption of optical pickocff 21 can be relatively large, thereby compare secondary ground with capacitance sensor 21 and optionally activate optical pickocff 21, is suitable.
In step S7, realize and check whether object 400 leaves the first peripheral region 11.In other words, can check that whether user moves and leave the region after the dorsal part 2d of motor vehicle 1 again, that is to say can identify by object 400 and leaves the first peripheral region 11.If this occurs, the releasing that realizes the optical pickocff activating in step S8 in step S6 activates.If from activating optical pickocff, that is to say and from implementation step S6, in 3 seconds, identify the time period of at least 2 seconds (step S9) that does not have object to stop presetting, also implementation step S8.
As long as do not leave the first peripheral region 11 yet identify by object 400, in step S9, check whether object 400 stops.If identify object 400 in step S9, do not stop, with step S7, continue (maximum 3 seconds) again.
Whether recognition object 400 stops realizing with different technology.For example likely, by means of optical pickocff 21 recognition objects 400, whether stop.To this, for example the characteristic point of object 400 can be differentiated as terrestrial reference and inspection or be followed the tracks of it in time with respect to the orientation of optical pickocff 21.For example, in a plurality of images that detect successively that also can consider optical pickocff 21 poor.Alternatively or additionally may check whether key 30 stops in the first peripheral region 11 by means of navigation system 100; If user's 401 carrying keys 30, deducibility goes out object 400 and stops thus.
If identify object 400 in step S9, stop at least two seconds continuously, with step S10, continue.In step S10, activate navigation system 100 (if its not by for step S9).Then in step S11, check whether key 30 is present in second week region 12 and whether the discriminating of key 30 causes sure checking, that is to say the key that whether has mandate.For example, to this, the authentication information of key 30 can be compared with the authentication information of motor vehicle 1.
By means of navigation system 100, check that the existence of key 30 can occur by sending the em field of rotation.In such form of implementation, can carry out to determine differing of em field by the measured a plurality of rotations of key (for example with respect to reference to phase).Based on a plurality of triangulation survey differing, then can determine the position of key 30; Based on determined position, can check whether key 30 is arranged in the second surrounding environment 12.
If use the electromagnetic field of rotation for the location of key 30, definite positioning precision of position can be larger-this situation especially relatively, and only the field intensity based on em field comes executing location to determine (as illustrated about 4th week region 14) above.For example in the situation that use the Em field rotating, in the first operational mode of navigation system 100, for definite key 30, the positioning precision detecting in the position of second week region 12 is several centimetres; And in the situation that use field intensity key 20 positioning precision in 4th week region 14 in the second operational mode of Em field to can be tens cm.Yet for obtaining the sending than sending the relatively more energy of consumption for what obtain the non-rotary EM of the second positioning precision field of em field of the rotation of the first positioning precision.Yet it should be understood that for the execution of the step S2 at 4th week region 14 finding keys 30 and can on the relatively longer time, carry out (if vehicle is arranged in inactive state).And if just meet the standard of step S5, S7 and S9 above, if determine that object, near corresponding closing element 3e, typically only performs step S10.
If find key 30 (step 11) in second week region 12, can in step 12, realize closing element, in the automatic manipulation of this luggage-boot lid 3d.The method finishes at step S13.
In step S14 and S15, realize the identification of the mistake the facing manipulation of closing element (at this luggage-boot lid 3d).To this, in step S14, utilize capacitance sensor 20 to carry out the identification of water wave.If for example a place in the capacitance sensor 20 in the B of motor vehicle 1 post identifies ripples, carry out at any time the method, as illustrated by means of step S1-S13 before, corresponding sensor 20,21, especially also have the releasing activation at the capacitance sensor 20,21 at luggage-boot lid 3d place, and the method finishes in step S13.
In step S15, realize pedestrian's identification.If identify pedestrian in step S15, be positioned at motor vehicle around, the method is moved to end again (step S13).For example to this, can use optical pickocff 21 and/or capacitance sensor 20.Alternatively or additionally also possible that, for example with lower repetition rate, carry out that key in step S2 is found or the inspection in step S5 and/or S6.Pedestrian identification for example can be carried out by means of the 3rd peripheral region 13: if by means of capacitance sensor 20 repeatedly survey first and the 3rd peripheral region 11,13 of adjacency through (pedestrian advances along vehicular sideview 2b the right or the left side, 2c), can infer thus that motor vehicle is parked in the frequent region of using by pedestrian.
Identification by means of the pedestrian in step S15 can further reduce energy consumption.Especially when step S2, S3, S4 are not performed and the capacitance sensor 20 of motor vehicle 1 also activates in inactive state, this is this situation.So the identification of the pedestrian by step S15 especially can stop in step S16, realize optical pickocff 21 needn't be frequent activation.
Although at length elaborated and illustrated the present invention by preferred embodiment, the present invention is not subject to thus disclosed example limits and can therefrom derives other variant by professional, and does not leave protection scope of the present invention.
The different task of differently distributing different sensors 20,21 can be especially for example possible.Thus can be only with optical pickocff 21 or capacitance sensor 21 carry out the identification that enters, stops and leaving.Also possible that, optical pickocff 21 recognition objects 400 enter in the first peripheral region 11 and the stopping of capacitance sensor 20 recognition objects 400.The most different variants is possible.
