Abstract

A method for coordinating operation of motor vehicles with a coordination device having a sensor, a computing device and a communication device includes determining from sensor data location and movement information of the motor vehicles, calculating an expected trajectory for each motor vehicle from the location and movement information, checking whether trajectories of different motor vehicles spatially and temporally overlap so as to create a conflict, in the event of a conflict transmitting a driving instruction to at least one motor vehicle, and executing the driving instruction or displaying the driving instruction on a display device of the at least one motor vehicle.

Claims

1. A method for coordinating an operation of at least one first and at least one second motor vehicle by way of at least one coordination device configured as a stationary infrastructure device or as part of a third motor vehicle and comprising at least one sensor, a computing device and a communication device, the method comprising:

recording sensor data with the at least one sensor of the at least one coordination device,

determining with the computing device location information and movement information of the first and the second motor vehicle by using the sensor data,

calculating with the computing device at least one expected trajectory for each of the first and the second motor vehicle by using the respective location information and movement information,

checking with the computing device the at least one expected trajectory for each of the first and the second motor vehicle for conflicts that occur due to a spatial and temporal overlap of the at least one trajectory of the first motor vehicle with the at least one trajectory of the second motor vehicle,

determining with the computing device a driving instruction for at least one of the first and second motor vehicle when a conflict has been determined to exist,

transmitting with the communication device the driving instruction to the at least one first and second motor vehicle, and

executing the driving instruction with the at least one first and second motor vehicle or displaying the driving instruction on a display device of the at least one first and second motor vehicle, or both.

2. The method of claim 1, further comprising

upon detection of the first and second motor vehicle by the sensors of at least two of the coordination devices and prior to determining the driving instruction, selecting one of the at least two coordination devices with the computing device of at least one coordination device or with a control device of the at least one first and second motor vehicle, with only the computing device of the selected coordination device determining the driving instruction.

3. The method of claim 2, further comprising

storing a corresponding motor vehicle priority information in the control device of the first and second motor vehicle, and

depending on the motor vehicle priority information, determining the motor vehicle having the control device that selects the selected coordination device.

4. The method of claim 2, further comprising

storing coordination device priority information in each the at least two coordination devices, and

determining the selected coordination device depending on the coordination device priority information.

5. The method of claim 2, further comprising

determining location information and movement information of the first and the second motor vehicle with the at least two coordination devices, whose at least one sensor detects the first and the second motor vehicle, and

determining an expected residence time of the two motor vehicles in a detection range of the respective sensor(s), wherein the coordination device is selected depending on the expected residence time.

6. The method of claim 2, further comprising

detecting with the at least one coordination device, which is not the selected coordination device, and its at least one sensor at least one of the first and second motor vehicle, and

transmitting to the selected coordination device at least one of sensor data, location information, movement information, and at least one calculated trajectory.

7. The method of claim 1, wherein the sensor is an image-acquisition sensor, further comprising determining at least one of the location information and the movement information of the at least one first and second motor vehicle using an image recognition algorithm.
