Description
Background technology
Present invention relates in general to the movability of the power actuated vehicle parked, and more specifically, relate to the drg or other vehicle motion controls that to use from outside and park cars, move to allow vehicle while the safety keeping vehicle interior article and improve safety in such moving process and time unattended.
Braking shift interlock (BSI) function, be also referred to as drg shift of transmission interlocking (BTSI), it is a kind of conventional anti-running theft function, the automatic transmission shift bar part of transmission gear scope selection mechanism is locked in parking position by it, just can only be released to make it when ignition lock is placed in operation or enable position---therefore need ignition key.As the insurance preventing unexpected movement further, also need from parking position release gear level the brake pedal depressing (namely starting) vehicle.When fastening and leave vehicle, at permission ignition key from before ignition lock removes, conventional BTSI system needs transmission shift lever to be placed in parking position further.The laws and regulations requirement of a lot of judicial district has such interlock, as the FMVSS 114 (FMVSS (Federal Motor Vehicle Safety Standard (US)) 114) of the U.S..
Typical BTSI system uses the electromagnetism return stop pin of spring-advance in the selection mechanism of gear scope, and it prevents gear level from moving apart (namely shifting out) parking position.Conventional transmission gear scope is decided to be PRNDL, comprises parking, reversing, neutral, driving, low speed.BTSI interlocks magnet coil and stop pin is optionally forbidden or permits being changed (i.e. reversing, neutral, traveling and low speed) to non-parking position by parking position.If electronic system malfunction or magnet coil release lock pin malfunction, according to FMVSS 114 similar regulation most of with the whole world, allow to use selectable, mechanical manual override, and it is included by maker usually.But the antitheft attribute wanted to keep some and the non-maintainability of prevention customer to it use, FMVSS 114 and most of similar laws and regulations requirement manual override design can only be used by instrument or key or operate.Be difficult to use and seldom use because the manual override mechanism of " keeping in repair special " is defined as, hardware is typically designed to and can only stands low frequency (i.e. low working cycle) use.If use frequent or used by non-trained service personnel, the manual override mechanism of the maintenance of these routines may be easy to damage.
Due to economy and complexity management, vehicle manufacturer wishes single hardware design to be used for specific vehicle usually, no matter where this vehicle sells world market.But, in demand, relevant laws and regulations and the consumer behaviour relevant to some hardware (override of the such as maintenance of BTSI system and its machinery), there is significant Territorial Difference.The scope of this species diversity is from the judicial district of forbidding the override comprising mechanical maintenance, and extending to those a lot of drivers needs routine use override and would rather delete the judicial district of BTSI.Such as, in some markets in South East Asia, the car that slips theft infrequently occurs.Therefore, the corresponding regulation of regulation BTSI system is not implemented.In addition, there is the feature of long-term parking space deficiency in a lot of urban districts of this area.In much such place, form convention, and be often required that double parking is (namely along edge, street with in parking area, become two parallel rows), stop car is placed in non-parking position (i.e. neutral) locking by making change-speed box, the Parking Brake of vehicle is closed, and wheel is in alignment simultaneously, so that they can push open by the driver of other vehicles as required, with close to by the parking stall stopped---be no matter when arriving or leave.Because most of South East Asia vehicle comprises manual gear change-speed box, and do not have BTSI or other prevent the function of neutral parking, this custom so developed easily.But this consumer behaviour has moved in the middle of the driver of the automatic transmission with hydraulic torque converter market part that this area increases gradually.Be equipped with the driver meeting the vehicle with automatic transmission of the override of the BTSI of FMVSS 114 regulation and the maintenance of machinery of standard, in order to the object of their " neutral " parking, be forced to use this override.Which results in and excessively use relevant problem with manual override, and manual override is defined as and only supports low working cycle, keeps in repair special use.In addition, the inconvenience of the designability used with instrument or key that FMVSS 114 specifies, result in discontented to its human engineering and ease for use of customer.
PCT patent application PCT/US10/21303 discloses a kind of configurable deceleration of electrons shift interlock override, and wherein the chaufeur of vehicle can be selected vehicle whether transmission for vehicles to be placed at him not allow other people to move the state (i.e. keyless neutral position) of vehicle in case in docking process.After taking-up key, in a time window, chaufeur is had an opportunity the parking shift (therefore vehicle can move) that swapped out by change-speed box.If do not completed in this time window, then vehicle activates key in the state of unclamping interlocking by being in need to use.So when not needing the moveable ability of vehicle (not being such as double parking), complete anti-theft protection can be kept.On the other hand, when must or needing to make vehicle be in removable state, it can be placed in neutral position and not stop movement to make change-speed box.
When using manual override (cause wheel of vehicle freely to rotate and be not subject to the obstruction of change-speed box), vehicle driver or vehicle owner must consider to slip the unattended or manual movement of the possibility of car-be no matter malfunctioning time.Typically, chaufeur only just stops when the gradient needs that wheel (as with timber wedge, fragment of brick or other larger objects) is to stop the vehicle accidental movement parked.In some cases, because the vehicle weight on steep slope makes to be difficult to maybe to realize manual movement (and stoping wheel to stop movement), the use of this meeting limit manual override.Alternatively, chaufeur can determine to engage parking brake and make vehicle be in released state and use parking brake to make the people of parking attendant or other expectation moving vehicles when they need moving vehicle.Perhaps, chaufeur or vehicle owner do not want in unblock situation, hinder wheel and park cars.In addition, suitable wheel may can not be always had to stop when needed.In addition, again stopping of the wheel after mobile completes by someone beyond chaufeur or vehicle owner, and can not complete in a satisfactory manner.
Summary of the invention
The present invention has following advantage: change-speed box be in neutral shift range and vehicle interior lock time cut-out and chaufeur do not keep an eye on time can engage parking brake, allow other people to unclamp parking brake by outside vehicle without key simultaneously.
In one aspect of the invention, multi-wheeled vehicle comprises electric parking brake (EPB), and it is in response to control signal optionally brake application device after storing cycle.The manual drives that input element is made in response to the external staff that parks cars produces command signal.Controller verification command signal and, if effectively, then produce control signal can move very short distance with temporary transient release the brake in parking area to make vehicle.At another fermentation of the present invention, this external control extends to affect vehicle ambulant other " line traffic control (by-wire) " system turns to, the control of throttle, transmission range and electric propulsion-to strengthen the movability that parks cars and safety further.

Detailed description of the invention
Present invention uses a kind of novel method controlling to be called the conventional apparatus of electric parking brake (EPB).Parking brake (mechanical parking brake device in the past or newer EPB) typically activates and stops from the single manual drives interface of vehicle interior as brake rod.EPB easily can make and drive interface or switch to make response to other that can add economically.In the present invention, any automobile electric opening/closing (the security keyboard as inputting without spoon) that can use from outside can pass through the change of relatively simple software and hardware in a novel way for control EPB.If if do not have existing external switch or switch to be in undesired position or configuration in particular vehicle design, then special external switch can be added for control EPB.Due to no matter vehicle lock or unlocked anyone can use external switch, so vehicle no longer needs to be set to freely slip car state to allow other people manually movement.As increase safety, when configure external control of the present invention time-be particularly placed in " neutral " state when vehicle time, EPB activate can with driver door's light switch and/or time meter self interlocking.
Except protection vehicle slips except car when unattended, the present invention also uses the EPB from external control, this can provide the extra feature strengthened, comprise: 1) when starting vehicle and moving, EPB is progressive, in checkly to unclamp, 2) after reaching maximum vehicle speed, automatic EPB reactivates or fluctuates (wherein control logic determines unserviced difference of slipping between car vehicle and the manual moving vehicle of having a mind to), and 3) EPB again application controls to replace the effort that manually stops thus reduce personal risk and allow vehicle to be parked in the position of expectation more accurately.If EPB lacks strengthen the part Engagement Control (namely can only open completely or completely close) of features for any these, then the motor-drive pump of service brake usage and electronic valve control (be generally used for and provide electronic stability to control (ESC) Braking system) and may be used for these dynamic brakes and strengthen function until vehicle stops and EPB engages again.
EPB can contact external switch to unclamp by single (supposing not stop vehicle to move, as when transmission for vehicles is in parking shift in addition).Alternatively, can use " pinning " pattern, wherein manual external switch must maintain to be unclamped by EPB when moving vehicle and to remain in "Off" state.Unclamping EPB also can with the particular order of switch drive for condition, if this order can inform the people expecting moving vehicle.
After vehicle moves, again apply EPB to be started by some diverse ways.Such as, the list produced by one or more external switch touches the application again activating and can trigger EPB.Alternatively, the application again of EPB can start, there is not excessive movement after one section of predetermined time delay after first time unclamps.In another embodiment, application again that is instant or time delay can start after unclamping initial " pinning " switch activator (namely unclamping EPB).Again applying EPB also can by other Event triggered that can appear in other Vehicular systems, as the object detection in object induction system, the too fast speed determined by velocity response system or the whole lock instructions from remote input transceiver.
The present invention can also the slope of sense vehicle park surface, if to prevent from stopping further movement by again applying EPB during the unclamping and be in dangerous situation or run into steep slope of EPB.If vehicle is equipped with the warning system with motional induction, then can automatically close to avoid false alarm during alarm algorithm when EPB unclamps.If vehicle is equipped with line traffic control, gearshift controls, then EPB unclamps and can also couple with the automatic change of automatic transmission shift scope from parking shift to neutral.EPB unclamps the feedback that EPB can also be provided as loudspeaker or vehicle parking lamp to have unclamped to user along with the activation of signal head.
When further reinforcement overcomes storing cycle, Steering gear can be locked in the potential problem in single position.There is the regulation of requirement lock for steering column the not every judicial district, and maker uses electric powered steering post lock in some cases.Therefore, when Steering gear is not locked or locks electronically and can temporarily not lock, the present invention increases the possibility changing steering angle when manual moving vehicle.Preferably, this embodiment strengthened applies electric boosting steering system (EPAS) and expands and outside use external switch that is existing or that add or other outside available human machine interface (HMI) to regulate steering angle electrically without spoon wagon control to allow user.An embodiment comprises two buttons using and security keyboard is not used in EPB control, plays a role as " pinning " key for the movement of left and right turn wheel.After the steering angle of setting desired locations, steering angle can with by continuing to be applied to EPAS system or keeping by again engaging electric powered steering post lock (if configuration) when moving vehicle subsequently by power.
Of the present invention another is strengthened employing elec. vehicle and is driven to produce the movable of the vehicle of motorized motions, (namely when vehicle is elec. vehicle, as hybrid power or all-electric vehicle).Use external control, battery electric power may be used for the switch that can be contacted by outside or HMI forward and backward self-driven vehicle.
Similarly, control if be equipped with the engine starting relay of module controls, electronic engine Throttle Opening Control and " line traffic control gearshift " transmission range, then can start and control to move on-electric or light hybrid vehicle before and after outside.In any embodiment that these are movable, closed loop control is more suitable for transmitting accurate, controlled acceleration/accel and end speed in this moving process.Similar with the use recently of the EPB as " ramp keeps (hill-hold) " device on the vehicle that hand-operated transmission is housed, the activation of automatic EPB and unclamp and can promote the movement of the motorized motions on the channel exceeding manual locomotivity by stoping vehicle to slip car between the input of effective instruction signal.
Any specific vehicle can comprise any subset that is above-mentioned and mobile relevant feature, but they are preferably turning to and/or adding by the order of braking before drived control.What the subset of the storing cycle function that the outside no matter particular vehicle comprises is controlled is, these functions all promote manually without the movement of spoon vehicle.This feature, preferably by software control, can set Sofe Switch to make the OEM/ customer of vehicle/chaufeur/vehicle owner so that any single feature of opening or closing in this stack features in controller HMI.When parking cars, therefore chaufeur can determine appropriate balance in parking period between the safety of vehicle and interior items thereof and other people ability based on stand moving vehicle.Although outside EPB is controlled can be designed as and is selected by the next controlled variator scope simultaneously of line traffic control gearshift control (if configuration); and it is unnecessary for making the parking shift of change-speed box be locked in when parking EPB; but preferably; the external control of all unlatchings of the present invention all will be opened or close (i.e. " parking shift "=closedown, " neutral "=unlatching) as a whole thus protect them to own by the key entry of single easy steps based on the range position be placed in by vehicle by chaufeur.
The difference configured by the distinctive regulation in market and user due to essentiality of the present invention drives, so the complete set affecting control module is respectively correlated with by the preferred embodiment of the invention, vehicle-mounted software brings any particular module of the vehicle sold on all world markets.Control logic arrange opened device depend on can set for guaranteeing to observe regulation and, as long as allow, just consider the one or more configurable soft bits of the hobby of customer, mark or code.This configuration bit can comprise for the vehicle assembling factory-program code of country of destination, for showing the software switch (its can setting Anywhere) in the use procedure of manufacture/transport/vehicle of the customer that customer self likes, and can monitor by the GPS of position, the current judicial district control dynamically labeled.
With reference now to Fig. 1, vehicle 10 comprises electric parking brake (EPB) actuator 11 be connected with wheel of vehicle 12 and 13, and it applies braking force in a conventional manner.Vehicle interior provides manual control panel 14, and it allows chaufeur apply or unclamp EPB11 equally in a conventional manner.Internal piloting 14 can be connected to EPB actuator 11 as shown in the figure or can be connected to independent control module 15 alternatively, and control signal is given to EPB11 by it.
In this preferred embodiment of the present invention, EPB actuator 11 and the external switch without spoon input keyboard 16 are connected by independent control module 15, as Body control module, use EPB function to provide outside.Therefore, control module 15 with there is being connected without spoon input keyboard 16 of independent button 17-20, independent button 17-20 allows the manual input of security password usually to be unlocked by vehicle based on secret button sequence.When being in parking mood, these safety of dual use and EPB function button can come (as pressed left/right button or press front/rear button simultaneously simultaneously) by the predetermined combination pressed the button simultaneously to switch between two functions.Because control module 15 judges safety keypad function usually, so this embodiment is not only avoided increasing the extra lead (directly connecting from keyboard 16) being connected to EPB11, and this module also more may have with other for verifying the existing use of the necessary signals of this kind of external control requirements.Alternatively or additionally, control module 15 can with other external switches as boot opening switch 21 or door handle switches (not shown) be connected, to make these other switch also can control EPB function.
The software of new or existing external switch and increase is used in control module 15, the present invention can provide the auxiliary control of traditional E PB module 11 to provide basic EPB functional, and wherein braking temporarily can unclamp that vehicle is moved very short distance in parking area.Preferably, controller verification is received from the command signal of external switch (i.e. input element) to guarantee that permission is functional and vehicle is in suitable state.
Control module 15 can be connected with other Vehicular systems to provide the functional of various reinforcement.Such as, powertrain control module (PCM) 22 is connected to provide vehicle speed data signal with control module 15.PCM22 also can be connected with inclination sensor (not shown) so that phase control module 15 provides additional tilt data-signal to identify the slope of vehicle environmental.Object detection module 23 uses remote sensing (as radar) to carry out inspected object and the imminent potential collision of alerting driver.If run into object, object information can be supplied to controller 15 again to apply EPB by module 23, sees below and illustrates.
Control module 15 is preferably configured to verify command signal, whether it based on whether allowing the parking function of only EPB (EPB-only) (being namely in neutral EPB to engage) and chaufeur or other in the specific judicial district has determined can use various park relevant with function, as EPB unclamps to the personnel that vehicle is responsible for.So, provide man-machine interface (HMI) 24 (it can comprise display and manual input switches) to enable various Sofe Switch or the mark of use in the people's configuration control module 15 in vehicle.In addition, config memory 25 comprises and can be allowed in various functional judicial district to represent whether vehicle is in by the mark of vehicle manufacturer or dealer's setting in advance.Config memory 25 can be positioned at any other suitable module of control module 15 or vehicle.It can also be connected to gps receiver 26 so that the database matching in functional config memory 25 of allowing of the position of the vehicle 10 making Current GPS determine and the various judicial district.
Relevant to the diversion functionality increased, directional drive 27 is connected with front-wheel 28 and 29.Actuator 27 controls by steer by wire apparatus controller 30.Steer by wire apparatus controller 30 is connected with external keyboard 16, directly or preferably by control module 15 connects, and it is applicable to the effective input of response to change steering angle.The checking of signal can perform based on the software tags from HMI24 and config memory 25.When installing electron beam lock 34, it suitably can be controlled by steer by wire apparatus controller 30 or control module 15.
In order to perform parking assisting function and not override change-speed box lugs in the whole process of storing cycle, control module 15 can be connected with transmission control module (TCM) 32.When TCM32 is line traffic control electric gear change system (i.e. line traffic control PRNDL scope select) a part of, and if when change-speed box shift interlock is not asked in the judicial district, then the outside instruction produced may be used for the temporary transient neutral be transformed into from parking shift position by change-speed box for performing manual parking action, or drives or stop the movable of power-assisted.
Control module 15 can also with car loudspeaker or other signal heads (as parking light or any other produce the device of perceived signal) be connected to provide feedback for the people attempting to promote vehicle.The perceptible information of this instruction request be verified enables user correctly estimate braking mode before physical effort promotes vehicle.If vehicle 10 is equipped with the circumference alarm 34 had for producing the motion sensor of alarm when parking cars and sensing motion, then provide the connection between control module 15 and alarm 34 to suppress to give the alarm in parking assisting function process.
Holistic approach of the present invention represents in fig. 2.In step 35, inspection is performed to determine whether to open any external control function by controller.If no, then this process completes in step 36.Otherwise, the input of controller wait-receiving mode in step 37.Once receive input just check its validity in step 38.If invalid, then next incoming signal waited for by controller in step 37.Checking in step 38 can preferably be made up of, to meet specific condition, as remained in " pinning " of the present invention embodiment the incoming signal checked from specific external switch.If effectively, then perform corresponding instruction in step 39.Rely on the specific input element (whether being namely the switch performing multiple function, during as button on use safety keyboard) used, the checking of signal can comprise instruction decoding based on the button pressed and the order pressed the button.
Fig. 3 shows the relation producing and be sent between the button signal of the command signal of control module and the response EPB state controlled by control module.In figure 3 a, button signal started in 41 moment.In " switching ripple (Switch Debounce) " embodiment, button signal must be kept predetermined time t
1to be identified as effective instruction.In figure 3 a, hold button is until appear at and compare t
1the moment 42 that time is long.As arrival t
1time, EPB state becomes the releasing orientation in 43 moment Fig. 3 B from engagement state.In this embodiment, drg continues to unclamp, until the activation next time of 44 times button signals.In 45 moment, EPB state gets back to engagement state simultaneously at 44 reception button signal (supposing to ignore switching ripple and signal processing time).
In another embodiment in fig. 3 c, the releasing orientation of EPB can continue predetermined time t
2.Therefore, EPB state is unclamped in 46 moment and is automatically again engaged in 47 moment.
In " pinning " embodiment, button signal must keep whenever opening independent function.As shown in fig.3d, button is pressed and was appeared at for 41 ' moment.In this moment, as indicated in figure 3e, EPB unclamps in 43 ' moment and keeps unclamping until 45 ' moment, and now button unclamped in 42 ' moment.
As shown in figures 3 f and 3g, external switch can pressed until the time of unclamping between EPB state introduces delay (namely " postponing to drive (Delayed Actuation) " pattern).Therefore, user presses the button in step 48 and produces releasing of brake instruction.Predetermined t delay time
3measured by control module, then EPB unclamps 49.This postpones to allow people's mobilizing function enter and promote the position of vehicle before the actual EPB of unclamping.
To unclamp and/or brake application can also perform in the mode of gradual change again.Fig. 4 represents an embodiment, is wherein illustrated by curve 50 being totally released (0%) and engaging completely the braking percentum between (100%).When activating EPB release function, braking reduces until reach zero 51 generally in drg percentum.The speed of the increase represented with velocity curve 52 manually promotes vehicle.In view of the object of safety, threshold speed 53 can be set to suitable value.When velocity curve 52 exceedes threshold value 53, brake and automatically again applied 54 by controller.Speed reduction can perform step by step until speed gets back to below threshold value.Drop to threshold value enough large following after, braking can be unclamped 55 and can get back to complete 100% 56 and be unclamped.The time-out of response braking function or respond other inputs stopping unclamping (as another switch activator of being caused by the people of outside vehicle or from another Vehicular system cognitive disorders thing or identify the input of excessive slope), recover to brake completely 57.Alternatively, the application again of EPB gradual change can be provided.
The preferred method of the present invention is illustrate in greater detail in Fig. 5.In step 60, detect " EPB closedown " in a step 60 or unclamp instruction.In a step 61, execution determines whether too precipitous inspection is so that safety unclamps EPB to vehicle environmental.If too precipitous, then terminate in step 62 process.Inspection in step 61 can also comprise other situations, as detected the obstacle stopped.Suppose in Fig. 5 that the command detection in step 60 comprises the checking of instruction.
If situation is acceptable concerning unclamping EPB, then signal head is used to make confirmation and closed safe alarm (preferably detecting a part for just safety system based on motion) in step 63.The optional delay can be introduced before release the brake in step 64.In step 65, upgrade the braking amount from EPB (and/or maintenance drg).Therefore, braking progressively can change between being totally released and activating completely.In addition, if needed, braking amount can fluctuate in some cases.When EPB drg is in loosen mode, make various for determine whether should the inspection of brake application device again.Therefore, in the step 66 by car speed and threshold speed T
srelatively.If be greater than threshold value, then in step 71, again apply EPB braking.If speed is less than threshold value, then makes in step 67 and checking to determine whether to exceed maximum time TT.If so, then in step 71, again EPB is applied.Otherwise, make in step 68 and checking to determine whether situation indicates to lose control of one's vehicle.Out of control in order to detect, controller is preferably monitored at the acceleration/accel braking vehicle in the process of temporarily unclamping, speed and shift length.If any one in these exceedes for normal manual vehicle moves the predetermined value of formulation, then think situation out of control, and again apply EPB drg in step 71.If the out-of-control condition of not being in, then make in step 69 and check to determine manually again whether application instruction is made by external switch.If so, then in step 71, again EPB is applied.If not, then check any other situation forcing vehicle to stop (needing the relevant detection of obstacle of acceleration/accel preventing the close velocity of braking force or exceed predeterminated level as having in vehicle route) in step 70.If these other situations do not meet, then in step 71, again apply EPB drg and this process completes in step 72.If other situations meet, then return step 65 to revise braking amount further if desired.
Fig. 6 shows the method allowing the reinforcement regulating steering angle.In step 75, actv. steering order is detected.In a step 76, inspection is made to determine whether that activating EPB unclamps.If no, then need not use turn to adjustment and this process complete in step 77.If activate EPB, then if necessary unclamp steering lock in step 78.In step 79, check steering order with determine its to when front steering situation whether effectively (on the direction allowing to turn to further as whether being in).If effectively, then use EPAS to change predetermined amount to perform steering angle, represent with x °, for " of short duration " embodiment, or for the time length of " pinning " embodiment.When actv. transition request no longer exists maybe when parking secondary status is no longer opened (again applying EPB), steering angle gets back to initial position alternatively and steering lock (if install) to lock and this process completes 82 in step 81.
In the existed system without BTSI manual override, shift of transmission scope can use the method shown in Fig. 7 to control.Therefore, EPB out code detects in step 85.Make in step 86 and checking to determine whether shift of transmission scope is in neutral.If so, then only as preceding method continues to run.If shift of transmission scope is not in neutral, then makes in step 87 and check to determine whether to allow override.Inspection can depend on the inspection software identification of vehicle owner as previously described or maker or dealer's setting.If do not allow override, then this process completes in step 88.Otherwise, in step 89, use the line traffic control shifting system of vehicle that drive range is changed into neutral.Then stop underaction, and shift range will get back to parking shift (not shown).
In of the present invention another is strengthened, vehicle 90 comprises and vehicle can be moved short range and drive to provide the elec. vehicle of parking assisting function.There is the EPB system 91 response external switch 93 of EPB controller 92.Same what be connected with switch 93 is EV drived control 94, and it provides motorized motions for wheel of vehicle 95 and 96.Switch 93 can preferably be made up of the key-board shown in Fig. 9.There is provided and have as shown in the figure for five independent switches that tradition is numbered without the tradition on each switch of spoon input keyboard.In addition, button can indicate to indicate drive actions forward and backward, the function turning to adjustment and EPB drg to open and close and to the right left with arrow.Particularly for the typical driver door position of this kind of keyboard, button 100 illustrates for connecting the forward directional arrow driving forwards action.Button 101 have represent vehicle to (namely right) side to upward arrow, and for make to the right turn to adjustment.The button 102 being positioned at center provides EPB Open-closure function.Button 103 illustrates the downward arrow of nearly (namely left) side representing vehicle, and for make left turn to adjustment.Button 104 comprises the arrow to the right for connecting drive actions backward.
