In another embodiment, the control command is an intervention in a control of the vehicle or an output signal for information of the driver. The intervention in the control of the vehicle has the advantage that compliance with the traffic regulations is achieved.

The use of an output signal as information to the driver that there is a misbehavior in relation to a traffic regulation can ensure that the driver adapts his driving behavior.

In another embodiment, the traffic regulation is received from an external data source. This makes it possible to access current traffic regulations.

In a further embodiment, in addition to the occurred faulty behavior of the driver and the non-compliance with traffic regulations is stored. Thus, it is clearly recognizable in which traffic regulation was a misconduct. This information can be used later.

In a further embodiment, it is checked whether a misconduct has already been stored for a traffic regulation, wherein a control command is issued only if a misconduct stored for the traffic regulation is present. Thus, the generation of the control commands, in particular the generation of output signals or interventions in the control of the vehicle is limited to traffic regulations to which there is already a stored misbehavior. Thus, the generation of a control command is issued only for the traffic regulations, for which in fact already is a misconduct, and for which further misconduct is to be expected. This avoids unnecessary control commands.

In a further embodiment, the control command includes the output of information that a misconduct has already been detected for the present or future traffic regulation. Thus, the driver's attention in addition to compliance with the specified traffic regulations can be increased.

In a further embodiment, the location of the misconduct is stored. Thus, it can be pointed to places where malfunction occurs more frequently.

In a further embodiment, the driver is determined and stored in addition to the misconduct. In addition, the control command is issued only for the driver for whom the misconduct is stored. This makes it possible to assign the misconduct to a driver. Thus, the detected misconduct can be used individually for each driver.

In a further embodiment, in particular in case of a recurrence of the same fault, in particular by the same driver as a control command, an intervention in the control of the vehicle is made to achieve compliance with the traffic regulations. This procedure offers the advantage that the intervention is preferably carried out only in the event of a recurrence of the misconduct. By considering the individual drivers of a vehicle, the intervention can be made depending on the individual driver's individual misconduct.

In a further embodiment, a traffic regulation is recorded, its scope is ahead on a route. If there is a misbehavior stored for the traffic regulation, a control command is generated before the validity range of the traffic regulation, in particular an indication of the traffic regulation issued. Thus, a driver can be warned in good time of a traffic regulation, which he has already violated.

In a further embodiment, information about the misconduct is output to external receivers, in particular to other road users, as a control command. The information can be transmitted optically, acoustically or via a data connection. In this way, other road users in front of a vehicle can be warned, which performs a misconduct. This can be used to point out, for example, a potentially dangerous vehicle or expected accidents. This can warn other road users of a dangerous vehicle.

Furthermore, the arithmetic unit stands 4 with a navigation system 17 in connection. The navigation system 17 has a route planning and a locating device for determining the position of the vehicle. The detection unit 8th is intended to be able to detect a driver of the vehicle individually. For example, the driver may enter a code for identification or use a particular coded key. In addition, however, devices for recognizing a person, in particular a camera with a face recognition, can also be used.

The input / output 7 is used to enter and output data and information to the driver. With the help of the communication device 5 can get data and information from the vehicle 1 sent out and from the vehicle 1 be received.

Furthermore, the arithmetic unit 4 with a controller 10 connected to the vehicle. The control 10 is designed to control various functions of the vehicle, in particular the speed of the vehicle.

In addition, a mobile memory 9 be provided with the control unit 4 connected is. The navigation system 17 also stands with the memory 6 or the mobile storage 9 in connection. In the storage room 6 Traffic regulations and their validity ranges are filed. For example, as maximum traffic speeds, overtaking bans, distances to vehicles in front, to be observed parking distances from intersections or pedestrian crossings, positions of traffic lights, predetermined directions, ie one-way streets, parking bans, etc. may be filed with appropriate scopes. In addition to the geographical validity ranges, temporal validity ranges for the corresponding traffic regulations can also be stored. For example, it may be specified in a defined area that only vehicles with a maximum pollutant emissions, for example no pollutant emissions, are allowed to drive the area. In addition, for certain vehicle types, eg. As trucks, driving on certain areas, especially at certain times, be prohibited.

Furthermore, in memory 6 or in mobile storage 9 Information about legal consequences in case of violation of traffic regulations. B. filed a fine catalog. In addition, data on assistance with legal violations such. B. Contact details of lawyers in the store 6 or 9 be filed. Furthermore, in memory 6 for given drivers register files can be stored on existing traffic violations of the corresponding driver.

Depending on the chosen embodiment, the described data and information stored in memory 6 or in mobile storage 9 are stored, even in an external second memory 15 be stored. The corresponding data are from the arithmetic unit 4 with the help of the communication device 5 from the external data store 15 read. This is the external data storage 15 with a second arithmetic unit 14 and a third communication device 13 connected. The second vehicle 2 has a second communication device 11 on and can according to the vehicle 1 be educated.

In addition, the first vehicle points 1 a second detection unit 20 on, with the traffic regulations, such as traffic signs, such. B. no passing, maximum speed, one-way street or markings on the road such. B. a solid line that indicates a no-overturn, can be detected. The second detection unit 20 also stands with the second arithmetic unit 4 in connection. The second detection unit 20 can be designed in the form of an electronic camera with image recognition software.

In addition to the detection unit 20 to For example, to detect traffic signs with an electronic camera, it would also be possible to identify cooperative traffic signs via C2X (= Car 2 Infrastructure) connection. So one could receive signals of cooperative traffic lights or traffic signs by means of a radio interface. This could be an additional radio interface in the vehicle 1 Provide (eg WLAN). The second detection unit 20 In another embodiment, it may be embodied either as a sensor (such as the mentioned camera) or as another radio module for receiving messages from cooperative traffic lights / roadside traffic signs.

In addition, the existence of a traffic regulation can be determined depending on the position of the vehicle. The position of the vehicle is determined by the navigation system 17 , which has the locating unit, determined. In addition, a digital map with information on the existence of traffic regulations on specific routes or route sections is stored in a database. Depending on the embodiment chosen, the digital map and / or the presence of traffic regulations in certain areas or locations may be accessed from an external database using the communications device 5 be received. For example, the external database is in the second store 15 filed and can via the second processing unit 14 and the third communication device 13 to the vehicle 1 be transmitted.

Depending on the chosen embodiment, the vehicle may 1 running a query to the second processing unit 14 judge whether there is a traffic regulation in the section of the route or on a section of line ahead. The vehicle 1 and in particular the arithmetic unit 4 are designed in such a way as to assist the driver of the vehicle in complying with traffic regulations. In this case, a valid for the driving route or for a future route to be traveled route is determined. The determination of the traffic regulation can, for example, with the help of the second detection unit 20 of the vehicle 1 respectively. In addition, the determination of the traffic regulation can also be done on the basis of a database, for example, in memory 6 is stored and has traffic rules associated with roads of a digital map. Furthermore, the information as to whether there is a traffic regulation on the route currently being traveled or on a route to be traveled in future can also be obtained from the external database, ie from the second memory 15 with the help of the communication device 5 , the third communication device 13 and the arithmetic unit 4 be queried.

The arithmetic unit 4 now checks whether the driving behavior of the vehicle complies with the traffic regulations. If this is not the case, then a control command is generated and the deviation of the driving behavior from the traffic regulation is stored as a misconduct. The storage can be in a memory 6 of the vehicle 1 or in an external memory 15 done with the help of a data transfer.

The control command may be an intervention in the control of the vehicle, so that the vehicle complies with the valid traffic regulations. In addition, the control command can represent an output signal for information of the driver that a valid traffic regulation is not met. This can, for example, haptically, visually or acoustically with the help of input / output 7 respectively. Furthermore, the driver can be displayed when outputting the information that a misconduct has already been detected for the present or future traffic regulation.

Depending on the selected embodiment, in addition to the misconduct the non-compliance with traffic regulations is stored. This is the arithmetic unit 4 known which traffic regulation was not respected. This can be used, for example, to check on detection of a valid on a traveled section traffic rule, whether for this traffic regulation is already stored a misconduct. If this is the case, then the arithmetic unit 4 for example, only generate a control command for already stored error behavior for this traffic regulation. This ensures that not with every traffic regulation a control command is generated.

Depending on the selected embodiment, a minimum number of incorrect behavior may also be stored for a traffic regulation from which a control command is generated. For example, for the generation of an output signal as information for the driver that a traffic regulation is not adhered to, the number of two stored misconducts may be stored for this traffic regulation. Only when two misbehaviours have already been stored for a traffic regulation, an output signal in the form of information is output to the driver in the event of a renewed misbehavior in relation to the traffic regulation.

In addition, for the generation of a control command for an intervention in the control of the vehicle, for example, a number of four incorrect behavior for this traffic regulation can be stored. This means that an intervention in the control of the vehicle is made automatically only with five stored misconduct compared to a traffic regulation.

In addition, in addition to the misconduct and the driver can be saved with. This offers the advantage that a misconduct is assigned to an individual driver. For this it is necessary that the vehicle 1 a driver recognition system. This can be achieved for example by assigning a coded key to a specific driver or by a camera with a person recognition method. This makes it possible for a driver to be informed of further misconduct depending on his or her misconduct. In addition, interventions in the control of the vehicle can be performed individually for each driver and their misconduct.

In addition, a traffic regulation can be recorded, the scope of which is ahead on a route. The driving route is the arithmetic unit 4 due to a route planning of the navigation system known. If a misconduct has already been stored for a preceding traffic regulation, then a control command can be issued even before the validity of the traffic regulation, in particular an indication of the traffic regulation. This method can also be controlled individually for different drivers. In addition, the generation of the control command can be controlled depending on a minimum number of existing misbehavior for the same traffic regulation, as already described above.

In a further embodiment, the control command is designed as an output of information about the misconduct to external receivers, in particular to other road users. The information can be transmitted optically, acoustically or via a data connection. As an optical display, for example, the hazard warning lights of the vehicle, a horn of the vehicle can be used as an acoustic indicator. To transmit the information over a data connection, a vehicle-to-vehicle communication connection may be used.

In another embodiment, the control command is a readout of information from a database, the information being output to the driver. The information may include, for example, a legal consequence of the misconduct and / or information about legal assistance, in particular contact details of lawyers or information on legal consequences on the Internet. In this way, the driver already receives information about the legal consequences of the misconduct immediately upon the occurrence or, for example, even before the occurrence of a misconduct. H. non-compliance with a traffic regulation. Thus, the driver can better evaluate his behavior. This ensures better compliance with traffic regulations.

In a further embodiment, the control command may be formed in such a way that the arithmetic unit 3 reads out information from a database and outputs it to the driver, wherein the information includes a register about already done wrong behavior of the driver. In addition, the information may preferably contain a legal consequence depending on the status of the register due to the driver's present or the expected misconduct. Thus, for example, the degree of punishment depending on the register, ie, for example, the point register of the driver, are issued to the driver. Thus, the driver can better judge the consequences of his misconduct. This is more likely to comply with traffic regulations.

In a further embodiment, depending on the legal consequence of the misconduct, an intervention in the control of the vehicle be made to comply with the traffic regulations. For example, in the event of an imminent loss of the driving license, an intervention of the arithmetic unit in the control of the vehicle can be made automatically in order to comply with the traffic regulations. Preferably, the limit from which an intervention is made in the control of the vehicle, the driver individually via the input / output 7 be specified.

In addition, the number of already stored misbehavior individually by the driver with the help of input / output 7 be established, from which, for example, an output signal is issued for non-compliance with a given traffic regulation or an intervention in the control of the vehicle to comply with the traffic regulation takes place. By assigning the misconduct to individual drivers, a driver can be alerted to his individual misconduct.

In addition, driver assistance systems such. B. traffic sign recognition systems, lane detection systems, distance measuring systems, etc. on the basis of known sensor systems such. As video, stereo video, photonic mixing device (PMB), lidar, smartphones, etc. are used to represent the functions described. Furthermore, the information about the driver's misconduct with respect to a traffic regulation can also be stored with the location of the misconduct. In this way, for example, the driver can be made aware that he often shows in the same place a misconduct. In particular, the driver can be notified in good time before the point at which he often indicates a wrongdoing.

By using the external database, current data on the existence of traffic regulations can be queried. For example, the data can be read via an Internet connection from a corresponding database. The legal consequences, d. H. the penalties can be read from a database. The database can be stored in the vehicle or in the external database (cloud).

The intervention in the control of the vehicle is designed in such a way that it is attempted that the vehicle does not violate the present or expected traffic regulations. For this purpose, for example, an intervention in the steering or an intervention in a brake system of the vehicle can be performed. For example, this can reduce the speed of the vehicle or avoid overtaking by the vehicle during a passing ban.

Access to external databases, for example via a car-to-interface communication system, the z. B. WLAN or LTE used. In addition, as a communication device 5 also a mobile device such. B. a mobile phone be provided with the computing unit of the vehicle z. B. Bluetooth is connected.
