Description

State of the art

The invention relates to a method for carrying out a traffic control, and to an apparatus for carrying out the method according to the invention. Moreover, the invention relates to a system for carrying out a traffic control, which comprises the device according to the invention.

In the document DE 10 2008 061304 A1 It is described that a driver of a vehicle gets displayed on a screen a map of the surroundings, on which all surrounding vehicles are shown. It is also described in this document about a choice to decide with which vehicles he wants to connect via a car-to-car communication.

An object of the invention is to further develop this concept so that it can also be used in traffic controls.

Disclosure of the invention

To achieve the object, a method for carrying out a traffic control according to the features of claim 1 and an apparatus for carrying out the method according to the invention are proposed according to the invention. In addition, to solve the problem, a system having the device according to the invention proposed.

In the method for carrying out a traffic control, first vehicle-relevant data of at least one vehicle is received by means of a first communication unit. In this case, for example, a Car-to-X communication connection is used. Vehicle-relevant data in this context can represent any type of information that can be detected via the vehicle and characterize the current state of the at least one vehicle. The data may already represent processed data in the form of, for example, images, but they may also represent, for example, raw data in the form of, for example, acquired sensor data. Depending on the received vehicle-relevant data of the at least one vehicle, at least a first control signal for a display unit is generated by means of a computing unit and subsequently the received vehicle-relevant data of the at least one vehicle is displayed by means of the display unit.

In a next method step, an indication for traffic control of the at least one vehicle is generated as a function of the displayed vehicle-relevant data by means of an input unit arranged outside the at least one vehicle. This notification signals the vehicle that a traffic control should be carried out in the future at least one vehicle.

Finally, in a last method step, the information for traffic control is transmitted to at least one second communication unit of the at least one vehicle by means of the first communication unit. In this case, the input unit, display unit, arithmetic unit and first communication unit are located outside the at least one vehicle, for example in the vicinity of a person responsible for traffic control, e.g. arranged by a police officer.

The present method makes it easier to notify vehicles about an upcoming traffic control. In addition, safety on the road is thus increased, since other road users who are not to be controlled are not blocked by conventional means, e.g. Blue light be unsettled.

Following the display of the vehicle-relevant data of the at least two vehicles by means of the display unit, a decision is preferably made as to whether the at least one vehicle is to be subjected to traffic control by, for example, a police officer responsible for traffic control. Preferably, the decision is made as to whether the at least one vehicle should receive an indication of traffic control by means of the arithmetic unit by chance. So there is no danger that some vehicle owners feel discriminated against. The decision as to whether at least one vehicle should receive an indication of traffic control can alternatively also be made as a result of abnormalities of the at least one vehicle by means of the arithmetic unit. An example of such an abnormality may be an increased speed of the at least one vehicle. Preferably, vehicle-relevant data are received from at least two vehicles by means of first communication units. For example, if there is currently only free capacity for a traffic control to be performed, a choice must be made between the at least two traffic control vehicles. Also in this case, the selection for a corresponding vehicle can be made, for example, as a result of abnormalities of the at least one vehicle by means of the arithmetic unit. An example of such an abnormality may be an increased speed. Alternatively, the selection can also be made randomly by means of the arithmetic unit. Input unit and Display unit are in each case outside the at least one vehicle, for example, in the vicinity of a person responsible for traffic control person, for example a police officer arranged.

Preferably, the vehicle-relevant data of the at least one vehicle represent a position of the at least one vehicle relative to a location of a traffic control station. For example, traffic control stations represent parking spaces on the edge of a roadway, onto which vehicles to be checked are guided and controlled there. Thus, vehicles can be informed early on the upcoming traffic control. Additionally or alternatively, the vehicle-relevant data represent at least one position of the at least one vehicle relative to the display unit and / or the input unit. For example, it may be that the display unit and the input unit are arranged in a police vehicle which is on patrol. Thus, this position would correspond to the position relative to the police vehicle and the police vehicle could follow the vehicle selected for traffic control.

Preferably, the received vehicle-relevant data of the at least one vehicle represent a trajectory of the vehicle. The trajectory of the vehicle represents the future trajectory of the vehicle, whereby not only the direction of movement, but also dynamic variables, such as the vehicle speed can be determined. From the trajectory of the vehicle, for example, the police can determine which vehicles do not adhere to the traffic regulations and accordingly select these vehicles for traffic control. Alternatively or additionally, the vehicle-relevant data of the at least one vehicle represent a destination of the at least one vehicle. The destination may, for example, represent the final destination of the at least one vehicle, which has been entered in the navigation unit of the corresponding vehicle. From this, the police can determine, for example, whether the vehicle is on its way to a safety-risky location.

The received vehicle-relevant data preferably represent an operating state of the at least one vehicle. This data may be any information that characterizes the current operation of the vehicle. Thus, for example, the information can be transmitted as to whether the vehicle's engine is actually switched on at all and / or whether passengers are currently inside the vehicle at all. In particular, the received data in this context may include information as to whether the vehicle is operated manually or automatically. This information is important in the context of traffic control, for example, because it can be deduced from which options are available for influencing the travel of the at least one vehicle.

Preferably, for example, it is determined that the vehicle is an automatically operated vehicle, so at least a second control signal for a longitudinal and lateral drive of the at least one vehicle can be generated. This second control signal is subsequently transmitted by means of the first communication unit via a car-to-X communication link to the second communication unit of the at least one vehicle. The vehicle can then be remotely controlled, for example to the location of the traffic control.

Alternatively, a third control signal for a navigation unit of the at least one vehicle is preferably generated. This third control signal may be, for example, a GPS signal of the location of the traffic control. The third control signal is subsequently transmitted by means of the first communication unit via a car-to-X communication connection to the second communication unit of the at least one automatically operated vehicle. By displaying the location of the traffic control on the navigation device, the driver of a manually operated vehicle selected for traffic control can then more easily control the vehicle for traffic control. For an automatically operated vehicle, for example, an adaptation of an existing vehicle route to an existing navigation system of the vehicle can be carried out so that the position of the police officer is represented as a new destination in the navigation system and taken into account in the navigation. The automated vehicle can then drive the new destination automatically.

Automated vehicles enable switching to manual driving. If, for example, it is determined that the at least one selected vehicle is currently being operated manually as a function of the received, vehicle-relevant data, but an automatically operated driving state is also possible, a fourth control signal is preferably generated and transmitted subsequent to the transmission of the traffic control indicator transmit the second communication unit. This fourth control signal generates a switchover of the automated operated vehicle from manual operation to automated operation. The driver of the vehicle is audiovisually notified to hand over the control to the automated vehicle so that the vehicle is operated autonomously.

Preferably, the communication between the first communication unit and the second communication unit of the at least one vehicle takes place in an encrypted form. In this case, for example, common methods of authentication are used.

Preferably, for example, by the police performing the traffic control, an input of an acknowledgment signal on the input unit that the traffic control of the vehicle has been completed. This confirmation signal includes, for example, the command "traffic control completed". The at least one vehicle can confirm receipt of the message by a car-to-X message and continue its journey towards the original destination. In this case, for example, the previously cached intermediate destination is loaded from a vehicle memory or from the cloud. Preferably, the vehicle can continue its travel only if it has received the command "traffic control completed". Otherwise, the vehicle is preferably locked for both manual and autonomous operation.

The invention also has a device which is designed to carry out the method according to the invention for carrying out a traffic control. In this case, the device has a first communication unit, which is designed to receive vehicle-relevant data of at least one vehicle. In addition, the device has an arithmetic unit which is designed to generate at least one first control signal for a display unit as a function of the received vehicle-relevant data of the at least one vehicle. In addition, the device according to the invention has a display unit configured to display the received vehicle-relevant data of the at least one vehicle. An input unit is designed to generate an indication for traffic control of the at least one vehicle as a function of the displayed vehicle-relevant data. The device according to the invention is in this case outside the at least one vehicle, e.g. in the vicinity of a person responsible for traffic control.

In this case, the display unit preferably represents a touch-sensitive screen or else called a touchscreen. Here you can create inputs by touching the screen. In such a touch-sensitive screen, the input unit can thus also be integrated immediately.

Preferably, the device according to the invention is integrated in a mobile unit. This may be, for example, a smartphone, a smartwatch or a tablet.

Alternatively, the device according to the invention is integrated in a vehicle. This may be a police car, the device being integrated, for example, in the cockpit of the police vehicle.

The first communication unit is preferably a radio device. It may, for example, be a mobile radio device which is designed to set up a Car-to-X communication connection.

The device preferably additionally has a remote control, which is designed to generate at least one second control signal for a longitudinal and lateral drive of the at least one vehicle as a function of the operating state of the at least one vehicle. This may be, for example, a joystick which is mounted on the device. A remote control by entering, so touching the touch screen would be conceivable.

In addition, the invention proposes a system which has the device according to the invention and a second communication unit of the at least one vehicle. In this case, the first communication unit transmits the generated indication for the traffic control to the at least one second communication unit of the second vehicle. Preferably, the system comprises a second display unit of the at least one vehicle, on which the traffic control notice can be displayed audiovisually. Preferably, the system has a second input unit of the at least one vehicle, by means of which input signals can be generated for the feedback of the received information for the traffic control. Preferably, the system additionally has a navigation unit which is designed to navigate the at least one vehicle to the location of the traffic control as a function of the at least one transmitted second control signal.
