Abstract

A method for operating a motor vehicle, including a first control unit, a second control unit configured separately from the first control unit and a surroundings sensor system for detecting motor vehicle surroundings, including: detecting the vehicle surroundings with the surroundings sensor system to ascertain surroundings data corresponding to the detected surroundings, checking with the first control unit based on the ascertained surroundings data, whether there is an object in the vehicle surroundings which could with a predetermined probability collide with the vehicle, to ascertain a first checking result, checking with the second control unit, based on the ascertained surroundings data, whether there is an object in the vehicle surroundings which could with a predetermined probability collide with the vehicle, to ascertain a second checking result, comparing the two checking results, driverless guidance of the vehicle, based on the comparison. Also described is a system, motor vehicle and computer program.

Claims

1. A method for operating a motor vehicle, the motor vehicle including a first control unit, a second control unit configured separately from the first control unit and a surroundings sensor system for detecting a surroundings of the motor vehicle, the method comprising:

detecting the surroundings of the motor vehicle with the surroundings sensor system to ascertain surroundings data corresponding to the detected surroundings;

checking with the first control unit, based on the ascertained surroundings data, whether there is an object in the surroundings of the motor vehicle which could with a predetermined probability collide with the motor vehicle, to ascertain a first checking result;

checking with the second control unit, based on the ascertained surroundings data, whether the object is in the surroundings of the motor vehicle which could with a predetermined probability collide with the motor vehicle, to ascertain a second checking result;

comparing the two checking results; and

providing driverless guidance of the motor vehicle based on the comparison, wherein the driverless guidance of the motor vehicle includes a fact that the motor vehicle stops automatically when the comparison reveals that at least one of the checking results confirms that the object is in the surroundings of the motor vehicle even if the other checking result confirms that the surroundings are free of the object.

2. The method of claim 1, wherein the surroundings data are transmitted from the surroundings sensor system to one of the two control units, the one of the two control units transmitting the surroundings data to the other one of the two control units.

3. The method of claim 1, wherein the surroundings data are transmitted from the surroundings sensor system to both control units.

4. The method of claim 1, wherein one of the two control units is a main unit of an infotainment system of the motor vehicle.

5. The method of claim 1, wherein one of the two control units is a control unit of a driver assistance system, in particular a parking assistant.

6. The method of claim 1, wherein one of the two control units is a control unit of a guiding device for driverless guidance of the motor vehicle.

7. The method of claim 1, wherein one of the two control units is an AVP control unit for carrying out an automatic parking operation.

8. The method of claim 1, wherein the comparison is carried out with one of the two control units.

9. A system for operating a motor vehicle, comprising:

a first control unit, which is configured, based on surroundings data corresponding to surroundings detected with a surroundings sensor system of the motor vehicle, to check whether there is an object in the surroundings of the motor vehicle which could with a predetermined probability collide with the motor vehicle, to ascertain a first checking result,

a second control unit which is configured separately from the first control unit, which is configured, based on the ascertained surroundings data, to check whether the object is in the surroundings of the motor vehicle which could with a predetermined probability collide with the motor vehicle, to ascertain a second checking result;

a comparator configured for comparing the two checking results; and

a guiding device configured for providing driverless guidance of the motor vehicle which is configured for providing driverless guidance of the motor vehicle based on the comparison,

wherein the guiding device is configured to stop the motor vehicle automatically when the comparison reveals that at least one of the checking results confirms that the object is in the surroundings of the motor vehicle even if the other checking result confirms that the surroundings are free of the object.

10. The system of claim 9, wherein a surroundings sensor system is for detecting the surroundings of a motor vehicle to ascertain surroundings data corresponding to the detected surroundings, one of the two control units being connected to the surroundings sensor system, so that the surroundings sensor system is able to transmit the ascertained surroundings data to one of the two control units, the one of the two control units being configured to transmit the ascertained surroundings data to the other one of the two control units.

11. The system of claim 9, wherein a surroundings sensor system is for detecting the surroundings of a motor vehicle to ascertain surroundings data corresponding to the detected surroundings, each of the two control units being connected to the surroundings sensor system, so that the surroundings sensor system is able to transmit the ascertained surroundings data to both control units.

12. The system of claim 9, wherein one of the two control units is a main unit of an infotainment system of the motor vehicle.

13. The system of claim 9, wherein one of the two control units is a control unit of a driver assistance system, in particular of a parking assistant.

14. The system of claim 9, wherein one of the two control units is a control unit of the guiding device.

15. The system of claim 9, wherein the comparator is one of the two control units, so that the comparison may be carried out with the aid of one of the two control units.

16. The system of claim 9, wherein one of the two control units is an AVP control unit for carrying out an automatic parking operation.

17. A motor vehicle, comprising:

a system for operating a motor vehicle, including;

a first control unit, which is configured, based on surroundings data corresponding to surroundings detected with a surroundings sensor system of the motor vehicle, to check whether there is an object in the surroundings of the motor vehicle which could with a predetermined probability collide with the motor vehicle, to ascertain a first checking result,

a second control unit which is configured separately from the first control unit, which is configured, based on the ascertained surroundings data, to check whether the object is in the surroundings of the motor vehicle which could with a predetermined probability collide with the motor vehicle, to ascertain a second checking result;

a comparator configured for comparing the two checking results; and

a guiding device configured for providing driverless guidance of the motor vehicle which is configured for providing driverless guidance of the motor vehicle based on the comparison,

wherein the driverless guidance of the motor vehicle includes a fact that the motor vehicle stops automatically when the comparison reveals that at least one of the checking results confirms that the object is in the surroundings of the motor vehicle even if the other checking result confirms that the surroundings are free of the object.

18. A non-transitory computer readable medium having a computer program, which is executable by a processor, comprising:

a program code arrangement having program code for operating a motor vehicle, the motor vehicle including a first control unit, a second control unit configured separately from the first control unit and a surroundings sensor system for detecting a surroundings of the motor vehicle, by performing the following;
