Description

The The invention relates to an apparatus and a method for reversible Adjustment of control systems on board a motor vehicle according to claim 1 or claim 17. Furthermore, the invention relates to a motor vehicle according to claim 16, equipped with such a device is.

modern Motor vehicles have a variety of electronically controlled Auxiliary functions, so-called driver assistance systems, which the Driver steering the motor vehicle in different situations to facilitate. Examples include lane detection systems, lighting systems, Pre-crash systems (cV) and distance warning systems to name. These However, help functions are usually dependent on whether the motor vehicle operated in legal or left-hand traffic is running. Thus, must in connection with the mentioned auxiliary functions presettings to be made which recognize the electronic control systems indicate in which mode the motor vehicle is operated.

Usually If such a presetting is already in the production of the motor vehicle factory performed. As a result, this default can no longer or only changed in a car repair shop become. This has often been considered by many users in the past been felt to be disadvantageous. In particular, the increased travel pleasure the population led to the need the default independent to be able to do it from a workshop. That way it would be possible, without any problem by car from a country with left-hand traffic to a country to enter with legal transactions, without the said auxiliary functions thereby impaired become.

task The present invention is therefore an apparatus and a Method for the reversible adjustment of control systems on board a motor vehicle specified, which allow the said flexibility.

These The object is achieved by a device for the reversible adjustment of control systems on board a motor vehicle having the features of claim 1 and a corresponding method with the features of claim 17 solved. Further embodiments of the invention will become apparent from the dependent claims.

One essential idea of the invention is now on board a Motor vehicle classification of the surrounding traffic in legal or On the left hand side and on the basis of the result of this classification to make the control systems of such auxiliary functions of the motor vehicle, which work depending on the type of traffic. Since the method is carried out on board the motor vehicle can or for that needed device can be easily installed in a motor vehicle, it is possible to changed Traffic types (eg when passing a national border from a Country with left-hand traffic to a country with right-hand traffic) flexible to react. So can looking for a car repair shop alone for changing the setting of Tax systems and the associated costs are avoided. The device claimed here for the reversible adjustment of Control systems on board a motor vehicle, has a detection means for determining whether the motor vehicle is in left-hand traffic or in right-hand traffic is operated on. In addition, a device for adjusting the Control systems depending on provided by the processor device determination provided. In a preferred embodiment of the invention, the recognition means is designed as a sensor system with processor device, the one Lane boundary and / or a lane center marker to the right or recognizes left of the vehicle, and deduces whether the motor vehicle is operated in left-hand traffic or in legal relations. As a sensor system can be an infrared radar or Camera sensor can be used. Preferably, the sensor system detects an area in front of the vehicle and is used for other driver assistance functions used.

alternative may be the information as to whether the vehicle is in left-hand or right-hand traffic is also over provided telemetric data. The telemetric data are by the detection means or a suitable trained receiving unit in communication with the detection means receivable. The telemetric data can be found especially in border areas be provided via radio. For a vehicle that has a Navigation system is equipped, for example, this information based on the current position transmitted by the navigation system will be provided and an electronic card, or derived from the current vehicle position data.

The classification is made using a camera already installed in numerous vehicles for other driver assistance systems. It is of course also possible to install such a camera specifically for the purpose of the present invention in a motor vehicle. The term "camera" in the context of the invention means any device which is capable of recording a sequence of images or environmental information.The camera can be mounted in the vehicle, in particular in the direction of travel, with the aid of such a camera time intervals pictures or informati Onen environment, as seen in the direction of travel recorded, and these images or information are supplied to the inventive device for evaluation. The transmission of such image data is known in the art and will therefore not be explained in detail here. The device according to the invention then makes an assessment or determination on the basis of the image data or environmental information as to whether the motor vehicle is in an environment in which left-hand traffic or right-hand traffic prevails.

• – eine Prozessoreinrichtung, die dafür ausgelegt ist, in von einer insbesondere in Fahrtrichtung vorderseitig an dem Kraftfahrzeug angebrachten Kamera aufgenommenen Bildfolgen vorgegebene Merkmale zu identifizieren und diese Merkmale nach einem vorgegebenen Schema zu klassifizieren und anhand der Klassifizierung festzulegen, ob das Kraftfahrzeug im Linksverkehr oder im Rechtsverkehr betrieben wird; und/oder alternativ

The inventive device for the reversible adjustment of control systems on board a motor vehicle has for this purpose the following:

• A processor device which is designed to identify predetermined characteristics in image sequences taken by a camera mounted in particular on the front side of the motor vehicle and to classify these features according to a predetermined pattern and to determine from the classification whether the motor vehicle is in left-hand traffic or in right-hand traffic is operated; and / or alternatively
• - A receiving device for receiving telemetric data (or at least a connection to such a receiving device), in particular navigation data to close from the current position data on the type of traffic (right / left traffic) can; and
• A device for setting the control systems as a function of the determination made by the processor device or traffic guidance derived from the telemetric data.

The Camera can also be directed to the rear, for example, the back aligned with the vehicle in the direction of the following traffic be.

there may be the means for setting the control systems in the processor device be integrated. As for the classification appropriate characteristics is a variety of characteristics imaginable. In the exemplary embodiments described below Some of these are indicated in the invention. It is for the expert in this field, however, readily understand that other features as are conceivable here, and the invention is therefore not limited to the examples given.

According to one embodiment In accordance with the invention, the given features include contiguous contours Vehicles and the given scheme includes the assignment whether the Oncoming vehicles appear on the left or right edge of the picture. The processor device counts according to this embodiment the number of oncoming vehicles, which they based on their Outlines identified, and divided the counted vehicles into those, which appear on the right edge of the picture and those on the left Picture border appear.

• – um einen links (bzw. rechts) entgegenkommenden Gegenverkehr handelt, oder
• – um rechts (bzw. links) am Fahrbahnrand abgestellte Fahrzeuge handelt, diese Information anhand der Differenzgeschwindigkeit zu den, bzw. gegenüber den zu zählenden Fahrzeugen gewonnen wird/werden kann.

In other words, it is determined on the basis of oncoming traffic, whether the motor vehicle is in an environment with right-hand traffic or with left-hand traffic. In the case of right-hand traffic, the oncoming vehicles in the left-hand side of the picture disappear in the case of a camera pointing forward in the direction of travel, while in left-hand traffic the oncoming vehicles disappear on the right in the picture. Explanation should be given to the completeness that for the determination or differentiation, whether it is the counted vehicles,

• - is a left (or right) oncoming traffic, or
• - To the right (or left) parked at the edge of the road vehicles, this information is based on the differential speed to, or compared to the vehicles to be counted won / can be.

Example: Corresponds to the differential speed with respect to those to be counted Vehicles equal to the vehicle's own speed, that's how it works around parked vehicles. If the differential speed is greater than the own vehicle speed, so it is an oncoming traffic.

According to one another embodiment of the invention, which alternatively or in addition to the above-described can be used, the device has a night mode, according to the given features include pairs of lights oncoming vehicles and the given scheme includes the assignment of whether the pairs of lights appear on the left or right edge of the picture. So here comes Pair of lights in the place of the outlines of a vehicle. With others Words counts Processor device here the pairs of lights, each of which one oncoming vehicle corresponds. There are only pairs of lights counted or evaluated, otherwise the traffic and at night the lighting on parallel roads the influence the above-described type of classification disturbing could. It is thus prevented by the exclusive evaluation of pairs of lights, that a street lighting erroneously as a vehicle is considered.

According to a further embodiment of the invention, the predetermined features additionally include the distance of the contours of oncoming vehicles or the pairs of lights to the motor vehicle. The distance or transverse offset of the opposite coming vehicles to own motor vehicle gives information about the structure of the road. The closer the oncoming traffic passes the car, the more likely it is to move on the same road. In this way, it can be ruled out that vehicles are counted by other, parallel roads, which could disturb the classification.

The Determining whether the motor vehicle is in left-hand traffic or in legal traffic moved, by means of predetermined steps, by the processor device accomplished become. The processor device is according to an embodiment designed so that the determination takes place depending on whether a predetermined threshold of a number of oncoming vehicles is exceeded on the left or right edge of the picture. The threshold can be set as an absolute number, or as a number of Vehicles per unit of time or distance unit. In other words For example, the processor device determines that the motor vehicle is moving in an environment with left-hand traffic, if in a period of time of x minutes y vehicles have appeared on the right edge of the picture.

According to one another embodiment the invention, the predetermined threshold is adjustable. The Setting can be done either by the user or by the processor device in dependence of certain criteria. An example of such criteria is the Traffic density, ie the total number of oncoming vehicles per unit of time or per unit of travel. The processor device is in this case designed to meet the given threshold dependent on of the total number of oncoming vehicles per unit time or automatically per unit of travel established. In this embodiment shows a particularly high flexibility of use, as the surrounding Traffic conditions in the classification can be considered. prevails For example, a low traffic density, so the threshold set accordingly low, so that setting down faster he follows.

at a further embodiment According to the present invention, the processor device is designed to that the classification and definition in the operation of the Motor vehicle continuously. This means that the Process of classification and determination continues to take place even if already an initial one Fixing is done. In this way, the device itself can correct. A first determination is made according to the invention as soon as possible exceeded the set threshold for the first time for a particular direction becomes. Then this direction is set as traffic direction and the control systems are adjusted accordingly. Nevertheless, will be the images supplied by the camera further evaluated, and if it turns out that now the threshold for the opposite Direction exceeded is corrected, the setting is corrected and the setting of Control systems is changed.

The Characteristics by which the classification of the processor device accomplished will, can according to a Prompt infrastructure between oncoming vehicles and the motor vehicle, wherein the processor device in This case is designed so that the classification depending on it is determined whether such an infrastructure exists. In the Infrastructure may be, for example, green areas, road boundaries etc. knew between oncoming traffic and the own motor vehicle. This can be largely excluded that vehicles on parallel roads be included in the classification or definition and thus they falsify.

Further Features can Contain outlines of edge development. The processor device is in this case designed so that the classification is dependent this is done, whether an edge development left or right of the vehicle is available. If, for example, an edge development to the right of the motor vehicle present, this is to be taken as an indication that the motor vehicle moved in an environment with right-hand traffic.

alternative or in addition can do this the features include lane markings. The processor device will be designed in this case so that the classification dependent on whether the lane markings are continuous or are broken. For example, by the processor device a lane mark with a continuous line on the right Recognized side of the vehicle, so this is an indication that the motor vehicle is in an environment with right-hand traffic is located, as usually roadsides with characterized by solid lines.

Also according to the invention a motor vehicle specified, which is a device for reversible Setting as described above contains. One Such a motor vehicle (eg car or truck) must be equipped with a camera equipped, which preferably central to the front of the motor vehicle is mounted. The camera is with the device according to the invention connected so that image data transmitted from the camera to the processor device can be.

As already mentioned, the present invention includes The invention also relates to a method for the reversible adjustment of control systems of motor vehicles. The method comprises the following basic steps: taking picture sequences with a camera, in particular centrally mounted on the front of the motor vehicle; Identifying predetermined features in the image sequences; Classifying the features according to a predetermined scheme; Determining whether the motor vehicle is operated in left-hand traffic or in right-hand traffic on the basis of the classification; and adjusting the control systems based on the determination made. The method may preferably be carried out using the apparatus described above.

Further can the given features include contours of oncoming vehicles and the given scheme may include the assignment, whether the oncoming ones Vehicles appear on the left or right edge of the picture (preferably each under consideration the differential speed to parked vehicles from oncoming To differentiate vehicles). On the basis of the count, how many vehicles appear on each edge of the picture, the Decision to be made, whether the own motor vehicle in an environment with left-hand traffic or with right-hand traffic.

Of others can, as already mentioned, at Application of the procedure at night the given characteristics Pairs of lights on oncoming vehicles and the given scheme In this case, the assignment may include whether the pairs of lights appear on the left or right edge of the picture. This embodiment is particularly advantageous when using the invention at night, because the oncoming vehicles work best by their headlights can be identified or identified. It should only be pairs of lights be evaluated, as this disturbing influences through other lighting (eg street lighting, lighting of buildings) excluded can be.

According to one embodiment the method according to the invention the given features additionally include the distance of the outlines oncoming vehicles or the pairs of lights to the motor vehicle. This embodiment is Understanding that the closer the oncoming traffic is to one's own Vehicle happens, the more likely he is on the same Street emotional. It is therefore a refinement of the method according to the invention, because in this way oncoming traffic, not on the same road, but moving on a parallel road, from the rating can be excluded. That means vehicles that are themselves in one too big Distance from your own car, not as accommodating Vehicles counted and thus not influence the determination.

The Can fix it also in dependence whether or not there is a predetermined threshold of a number of oncoming vehicles is exceeded on the left or right edge of the picture. The threshold can be determined with regard to which measures are to be taken exclusion from sources of error. Is the process only relative coarse, d. H. will not be any of the measures outlined here to exclude sources of error, the number becomes the threshold be higher because the security is higher is, the more vehicles as a hint until the threshold is reached needed become.

at an embodiment According to the invention, the predetermined threshold value is dependent on the total number of oncoming vehicles per unit time or set automatically per travel unit. This means that the Traffic density is taken into account when setting the threshold becomes. In this way, the practicality of the method according to the invention or its user comfort further increased.

If this desired is, the classification and the setting in the operation of the the motor vehicle continuously. That way is the determination always up to date and if necessary occurred misstatements and / or changes in traffic management (eg. B. at a border crossing) will be corrected immediately.

According to one embodiment the method according to the invention also the infrastructure of the environment becomes the decision of the question, whether the motor vehicle is in an environment with legal traffic or moved with left-hand traffic, included. In particular, this is the infrastructure, z. B. green stripes or other road boundaries like Guard rails etc., between the vehicles suitable, because thereby It can be decided whether an identified vehicle is on the "own" street is located or on a parallel or approximate parallel. In the latter case, the recognized Vehicle namely not included in the rating. Thus, according to this embodiment the characteristics infrastructure between oncoming vehicles and the motor vehicle and the classification is dependent of whether such an infrastructure exists.

Alternatively or additionally, the features may also include outlines of edge development and the processor device is designed such that that the classification takes place depending on whether there is an edge development left or right of the motor vehicle. If z. B. recognized that is located on the left of the motor vehicle development, it can be concluded that the motor vehicle is located in an environment in which left traffic prevails.

On similar As in the previously described embodiment, the Features also include lane markings and classification takes place in dependence whether the lane markings are continuous or broken. As well as the edge development provide continuous lanes on one side of a motor vehicle an indication of the presence of the roadside edge at this point is the edge of the road immediately recognized on one side of the vehicle, so it can be a direct conclusion drawn on the type of traffic (right-hand traffic or left-hand traffic) become. About that In addition, this embodiment also suitable misinformation by oncoming vehicles, who are not on their own street.

Further Advantages and applications The present invention will become apparent from the following description in conjunction with the embodiments illustrated in the drawings.

In the description, in the claims, in the abstract and in the drawings are those in the listed below List of reference symbols used terms and associated reference numerals used.

The Drawings show in

1 a schematic representation of the individual elements of a device according to the invention;

2 a flowchart with the essential steps of a simple embodiment of a method according to the invention; and

3 to 6 individual steps of a continuous process according to the invention.

in the Following can identical and / or functionally identical elements with the same reference numerals be provided. The absolute values given below and dimensions are only exemplary values and do not represent a limitation of Invention on such dimensions.

1 schematically shows the essential elements of a device according to the invention. The reference number 1 denotes a camera or similar device for recording image data. It should be noted that the camera is not necessarily part of the device according to the invention for the reversible adjustment of control systems on board a motor vehicle. So can be used on a camera that is already present in the vehicle, in which the device is to be installed. In this case, only the existing camera with the device according to the invention must be connected in a suitable manner, so that the recorded image data can also be used by the device.

Like this in 1 can be seen, the camera is to a processor device 2 coupled, which represents an essential element of the device according to the invention. In the processor device, the steps of identifying predefined features in the images supplied by the camera and of classifying the identified features according to a predetermined scheme are performed. Suitable software programs for this purpose can be readily written by those skilled in the field of computer science and for this reason, they should not be detailed here. In the processor device 2 Furthermore, the determination or decision is made as to whether the motor vehicle is in an environment with left-hand traffic or with legal traffic, based on the recognized and classified characteristics.

Under the reference 3 is finally a device for the reversible adjustment of control systems 4 shown on board the motor vehicle. The adjustment is made on the basis of the determination made by the processor device. With the device 3 thus become the tax systems 4 for certain vehicle functions, e.g. As light systems or lane detection systems, controlled and set to left-hand traffic or right-hand traffic. Like this in 1 can be shown in a motor vehicle according to its equipment or the vehicle class several such control systems 4 to be available. These are all from the same facility 3 set. It should be noted that the elements 2 and 3 , which represent the device according to the invention, can also be designed as a single unit.

Regarding 2 Now, the essential steps of a method according to the invention will be illustrated with reference to a simplified scheme. As can be seen in the figure, a step S1 is first carried out, which comprises taking pictures or image sequences with a camera. These images are preferably continuous, ie over a longer period of time, with a suitable number of images per Time unit is recorded.

The Images are analyzed in a second step S2, which means that are examined for the presence of given features. The features may, for example, be more responsive to the outlines Vehicles act. The presence of each individual feature becomes registered, and then The features thus identified are modeled according to a given scheme classified. In the given example, the schema is an association of vehicles to the right of their own motor vehicle in the picture are recognizable (right picture border), and of vehicles, on the left from own motor vehicle in the picture are recognizable (left edge of picture).

In one next Step S3 is determined on the basis of the classification made or decided whether your own vehicle in an environment with right-hand traffic or with left-hand traffic, if the collected Data already sufficient at this time. Is such a decision already possible at this time z. B. because a certain threshold of on a certain Side oncoming vehicles has been exceeded, so will the determination is made, and based on this determination takes place in one next Step S4 the setting of the control systems. Then be However, more image data is collected and analyzed, so the once can be revised if new data becomes available make other determination necessary. Is in step S3 on the base the data collected up to that point in time is not yet possible; Because a predetermined threshold has not yet been reached, so step S1 is also continued.

The above-mentioned method steps are described below with reference to a specific embodiment with reference to the 3 to 6 explained in more detail. In the embodiment, the features on the basis of which the determination is made represent outlines of oncoming vehicles. According to the predetermined scheme, a classification corresponding to left and right, respectively, is made at the image edge of detected vehicles. A decision or determination takes place according to this embodiment, when a predetermined threshold for right or left emerging vehicles is reached.

The right-value axes of 3 to 6 specify a measure of the filter value, ie the number of vehicles counted in each direction, and the high-order axes reflect the sign of the traffic.

In 3 a first phase of the method according to the invention is shown, which will be referred to below as the initialization phase. In this initialization phase, no predetermined threshold has yet been reached. The threshold is shown in this figure as an arrow on the value axis. A filter value is modified for each recognized oncoming vehicle as a function of the lateral distance (the closer the vehicle is to its own motor vehicle, the greater the change) and the side (sign of change) at which the vehicle passes its own motor vehicle. If the filter value reaches the predetermined threshold value on one of the sides, it is hypothesized that it is the appropriate type of traffic, ie a determination is made. On the basis of this determination now the attitude of the control systems takes place.

In 4 the state is shown that the predetermined threshold has been reached on the right side. The upward arrow indicates this condition. Now the initialization phase is completed. Nevertheless, further image sequences are recorded and evaluated. If it can be concluded from the pictures taken below that the first hypothesis or determination no longer applies, then the hypothesis is corrected.

In order to Once the hypothesis is reversed, it must be changed accordingly many vehicles on the other side, so the side starting from the current hypothesis is the wrong side, the own vehicle happen.

5 shows the condition according to which more and more vehicles are counted on the opposite side. This is indicated in the figure by the arrow pointing to the left.

In 6 finally, the threshold number of vehicles on the corresponding image page is reached and thus the initial hypothesis is corrected and the determination is made that the environment of the vehicle is a left-traffic environment.

As already mentioned, becomes the method according to the invention according to one embodiment carried out continuously, which means that the steps of picking up, identifying, Classify and repeat the assignment. Stay that way the settings of the control systems always up to date.

With the device according to the invention or the method according to the invention can be conveniently control devices of directional vehicle functions adjust without the user of the vehicle this for a workshop must give.
