The absolute position of known another characteristic.Additionally, vehicle can store institute's identification feature relative in navigation system store
The relative position of useful information (such as traffic marking board or building or street corner or bend intermediate point).
In addition additionally storage is directed to the identification information of sensor used, for obtaining feature.The identification information
For example it is capable of the information of the installation site including the sensor in type and/or vehicle on sensor.Thus, it is possible to for example
Calculate relative distance of the sensor relative to the GPS positioning device of vehicle such that it is able to more accurately determine acquired feature
Absolute and relative position.Additionally, being capable of identify that be characterized in as acquired in which kind of sensor type based on the identification information
's.Thus can for example mark and analyze the feature of same or similar sensor together.It is furthermore possible to separate place's reason not
Feature acquired in same sensor.Precision thus, it is possible to improve the method.
Another design of the invention is to collect and analyze multiple on such as one car or different vehicles
The information of traveling.For example can center computing unit in storage, analysis information, i.e. additional information, and it is transmitted again to
Vehicle.
Fig. 2 shows the system for being carried out middle ground collection data as other computing units 19 by means of server
Schematic diagram.Vehicle 13 is crossed a certain section and the absolute position of additional information, i.e. feature and feature is recorded by means of sensing system 4
Put or feature relative to known useful information relative position, useful information is, for example, the thing with known local position
Body.This feature for example can also be traffic mark, such as by means of the traffic mark of video sensing device identification.It is furthermore possible to obtain
Runway geometry is taken as feature, such as recognizable structure of vision or the element describing on the runway surface runway are several
What shape.
Relative position of the vehicle 13 by the feature as acquired in vehicle and the position of feature or feature relative to useful information
Transmitted by interface 20 to the computing unit 19 in center, the central computing unit equally includes second interface 21.In the center
Computing unit 19 in, collect the additional information from different vehicles, and by means of data aggregation compress these additional informations.
If for example, having holded up one piece of new traffic mark, the traffic mark is not yet stored as useful information, then the traffic mark is same
Sample can represent the feature of additional information.It is erected at traffic mark (speed limit 60km/h) before bend.The curvature of bend has peak point,
Reason for safety does not allow traveling to be faster than 60km/h at the peak point.Traffic mark (60km/h) and the song with restriction
The bend geometry of rate represents useful information.Meanwhile, " useful information traffic mark " can also act as having relative to bend
The feature of the relative position (such as 120 meters) of the peak point of maximum curvature.As long as video sensor detects traffic mark, then
Just there is known the accurate position of peak point of the vehicle relative to the bend with the curvature for determining.In this case, the friendship
Logical mark both can serve as useful information (for the function of such as speed precaution device), can serve as again for determining before bend
Relative position feature.
In another form of implementation, passed when many vehicle identifications to same traffic mark and by position or relative position
When transporting to computing unit 19, for example, the traffic mark information for determining very much can be realized, it has the accurate of the traffic mark
Position data.For example vehicle can obtain traffic mark and by traffic mark and traffic mark by means of different video sensor
Location transmission to computing unit.Therefore, video sensor exemplarily includes image-recognizing method, by means of the image recognition
Method is capable of identify that the species of the traffic mark.
Exemplarily can be by means of image-recognizing method traffic mark of the identification with 60km/h rate limitations.For example,
If 18 vehicle identifications are to the rate limitation of 60km/h, and only two vehicles recognize the rate limitation of 90km/h, then
The analysis that computing unit can be based on statistics thereby determines that the rate limitation that the traffic mark board as acquired in vehicle is represented is
60km/h.The information can again be sent to vehicle.Thus, once recognizing the vehicle of the traffic mark for making mistake can also sail next time
The out-of-date traffic signboard for recognizing that the rate limitation is 60km/h based on the information provided by computing unit, although the video of vehicle
Sensor has perhaps been damaged.
Center computing unit 19 in, for example can sensor-based identification information recognize whether some vehicles include
High-precision sensor.Thus, for example when data are assembled, preferably consider or considered with high-precision with Factors Weighting
The data of sensor.
Exemplarily, absolute and/or relative position the average value of acquired feature can constitute data aggregation.For example
If there is the data from inferior sensor and the data from quality sensor very high, then for example can only make
It is for example to store the absolute position of feature or the relative position of feature and it is defeated again with the data of quality sensor very high
Go out to vehicle.
Exemplarily, there are the vehicles of different video sensors when many by traffic mark and by acquired feature
When reporting the computing unit 19 to center with position or relative position, the reliable friendship with better position quality can be realized
Logical identification information.High-precision runway geometry, such as bend can be equally obtained in this way.It is this by example
Property ground obtain many vehicles same place exercise data.For example can by such as video sensor, steering angle sensor and
The sensor of gps system obtains exercise data in the form of such as curve movement.Can be bent by means of data aggregation compression motion
Line, for example, constitute average value.Therefore, central computing unit 19 can obtain valuable and high-precision on vehicle periphery
The information of environment and transmit it to vehicle.
Thus vehicle can show miscellaneous function and consider the information that will be provided in order to such as perspective.The information energy
Enough it is such as traffic mark information or runway geometry.Therefore, vehicle can from center computing unit 19 and/or from its
The information of position of his vehicle receiver on feature and feature.Vehicle can be combined this information with to local navigation ground
Figure.Known method, such as map match can be used herein.Due to numeral map inexactness and GPS location it is not smart
True property, can be by means of the data for additionally obtaining, i.e., the improvement of acquired feature and its position realization positioning.
For many miscellaneous functions, there is the demand of the position of positioning vehicle as accurately as possible, such as too quickly
Automatic brake hard before the bend of traveling.Therefore, for example can to vehicle provide acquired feature and it is acquired with
The relative position of the relevant feature of bend peak point.Exemplarily, this feature can be the crack on runway surface, runway table
The pitch spot or runway in face or other structures of environment, such as draining inlet for stom water.Therefore, vehicle is obtaining stored spy
In the case of levying can than more accurately or earlier being calculated by means of traditional navigation data to the distance of bend peak point, and
Brake hard behavior is for example automatically introduced into earlier and/or more rightly.Therefore, vehicle possesses corresponding computing unit 18 and phase
The control unit answered, the control unit participates in Vehicular system, such as engine, clutch, brake.
These features can be used in storing the position of useful data, and useful data is, for example, the friendship of the position relative to feature
Logical mark or street geometry.Vehicle stores feature, acquired feature and useful letter in the data storage of its own
Relative distance between breath (such as identified traffic mark).Vehicle by feature, acquired feature and useful information (for example
The traffic mark for being recognized) between relative distance transmit to outside computing unit 19.Outside computing unit 19 believes this
Breath is pass on to other vehicles, so that travelling the identical section on the runway afterwards and recognize for example
The vehicle in the crack in runway can additionally use the information, i.e., exist with 60km/h rate limitations at 20m
Traffic mark.
In this way, follow-up vehicle can carry out its current location relative to useful letter using the additional information
The high-precision positioning of breath.Therefore, the information transfer on feature and its position that will preferably be assembled is to vehicle.Follow-up
Vehicle is based on its navigation preview by means of GPS location and the visual field of exemplary electronics, identifies it close to useful information (such as
Traffic mark or the runway geometry of determination).The information also relative coarseness.When the sensing device of vehicle is known in its environment
It is clipped to feature, then its relative distance between known another characteristic and useful information that can be based on being transmitted determines vehicle
It is also how far apart from useful information.Can driver assistance system be activated in time for example to reduce speed in this way.
Also can happens is that, different vehicles are deformed using different sensors.Therefore, according to the difference of manufacturer,
The video sensor of identifying rows lane boundary can have image resolution ratio higher or relatively low.The sensitivity of brightness or color
Sensitivity can be different.Feature, such as crack, pitch spot, mark can be obtained using the deformation of all of sensor
Know board etc..Here, the signal as acquired in sensor very can differently be drawn.For radar or laser radar sensor
It is as the same.Analogously it is possible to radar or laser radar sensor are used to recognize the object of surrounding, but in identification feature, this
The signal of a little sensors can be very different, and depend particularly on resolution ratio, visual angle and the technology for being used.Extreme
In the case of, vehicle obtains feature using the video sensor (such as in the form of traffic mark camera) for disposing forward.Its
His vehicle for example can obtain feature using the video sensor (backup camera) for disposing backward.Acquired feature,
I.e. the signal of sensor by because different cameras, different objects, different visual angles and/or different installation sites without
Together.Therefore, another design is devised：Sensor for obtaining feature also includes sensor information, i.e., on it certainly
The identification information of body, it is also stored in the computing unit of outside.Therefore, outside computing unit can store different biographies
The control signal of the acquired feature of sensor deformation, and by sensor identification information come mark sensor signal.Set at this
In meter scheme, follow-up vehicle for example may send its sensor information to the server in center, and afterwards except useful data,
Sensor signal is only obtained as the reflection to feature and its position, the sensor signal is deformed by the sensor that vehicle also possesses
It is produced.
Thus, it is possible to select to transmit data to vehicle from computing unit and during it to be correspondingly matched to vehicle it is existing
Sensing system.The transmission of unnecessary data is avoided in this way.
Additionally, computing unit 19 is also capable of the sensor signal of average identical sensor, to obtain for feature most
Excellent sensor signal.Also can replace averagely improving sensor signal using other kinds of method.Thus, it is possible to optimize
Sensor signal, and improve the identification to same feature from there through another car.
Computing unit 19 transmits data, the data especially assembled, the i.e. feature of such as determination to other vehicles 14
Vision signal and the determination feature position.Other vehicles 14 for example obtain vision signal by means of video frequency pick-up head.
Vehicle by acquired vision signal with it is being stored and compared by the vision signal that computing unit 19 is transmitted.According to such
Compare, whether both vehicle identifications are same vision signal.Thus, vehicle can be by the position of the feature being consistent with vision signal
Or relative position is used to guide vehicle.Vehicle for example identifies according to additional information, to knowing the distance that another characteristic determines
Place's placement useful signal, such as traffic mark.Distance thus, it is possible to be accurately determined vehicle to traffic mark.
The method is not rely on the species of used sensor.Additionally, computing unit 19 can use different biographies
The signal of sensor, with the identification of calibration feature.Exemplarily, vehicle can be obtained at defined location by video sensor
Street well lid and by the signal transmission of video sensor to computing unit 19.Additionally, same or other vehicle are by means of it
His sensor, such as radar sensor, obtain the reflection that improves of the signal at defined location and transmit it to meter
Calculate unit 19.Computing unit 19 is based on the characteristic feature that the signal identification of different sensors exists at defined location.By
This improves the security of feature recognition.
