Abstract

A method for operating a motor vehicle incorporates polling regarding the control of the motor vehicle, leading to an improvement in the working conditions of a plurality of evaluation units accessing sensor units of the motor vehicle. Control commands for controlling the motor vehicle are determined from this polling by a conflict checking unit. The conflict checking unit determines the feasibility of the control commands, taking into consideration predetermined verification criteria with regard to conflicts between the individual control commands and the practicability of the individual control commands. The conflict checking unit also determines a control specification for a vehicle control unit based on the feasibilities and certain decision criteria. Finally, the motor vehicle is controlled by use of the vehicle control unit in accordance with the control specification.

First claim

The invention claimed is:

1. A method for operating a motor vehicle, the motor vehicle including evaluation units which access sensor units of the motor vehicle, a conflict checking unit, and a vehicle control unit configured to control the motor vehicle, the method comprising:
ascertaining, by corresponding evaluation units, requests relating to a control of the motor vehicle for improving working conditions of the evaluation units which access the sensor units;
communicating the requests to the conflict checking unit;
ascertaining, by the conflict checking unit, control commands to control the motor vehicle by the vehicle control unit to implement the requests;
ascertaining a respective feasibility of the control commands based on predetermined verification criteria with respect to contradictions of each of the control commands with each other and a practicability of each of the control commands;
ascertaining a control specification for the vehicle control unit based on the feasibilities of the control commands and predetermined decision criteria; and
controlling the motor vehicle according to the control specification by using the vehicle control unit.

2. The method according to claim 1 , wherein
ascertaining the requests by the corresponding evaluation units includes accessing individual sensor units among the sensor units, accessing sensor systems, and/or accessing a driver assistance system, and
the method further comprises providing data which is recorded in the motor vehicle to the evaluation units and/or providing data which is communicated to the motor vehicle to the evaluation units.

3. The method according to claim 1 , wherein ascertaining the respective feasibility of the control commands includes:
determining whether contradictive control commands exist due to a plurality of requests of one of the evaluation units and/or due to target conflicts of control commands based on requests of different evaluation units, and/or
determining the practicability of each of the control commands based on current road conditions, traffic conditions, and/or a current travel route of the motor vehicle.

4. The method according to claim 1 , wherein ascertaining the control specification includes estimating advantages which are to be expected upon performing respective control commands, the estimating advantages including estimating an expected improvement to the working conditions of the evaluation units which access the sensor units.

5. The method according to claim 4 , wherein ascertaining the control specification includes estimating disadvantages which are to be expected upon performing respective control commands.

6. The method according to claim 5 , wherein ascertaining the control specification includes relating the advantages and disadvantages to each other based on predetermined evaluation rules.

7. The method according to claim 6 , wherein the predetermined evaluation rules include a ranking of the predetermined decision criteria.

8. The method according to claim 1 , wherein the predetermined decision criteria includes:
a safety risk for occupants of the motor vehicle,
a safety risk for motor vehicles, persons, and/or objects in an environment of the motor vehicle,
a comfort measure for the occupants of the motor vehicle,
a gain in time for the occupants of the motor vehicle,
an energy saving of the motor vehicle,
an emission reduction of the motor vehicle,
an improvement of the working conditions of the respective evaluation units,
an effort associated with control of the control commands for the vehicle control unit, or
an effect of the control of the motor vehicle with respect to a current travel route of the motor vehicle.

9. A control system for operating a motor vehicle, the control system comprising:
a vehicle control unit; and
a conflict checking unit configured to:
receive requests relating to a control of the motor vehicle for improving working conditions of evaluation units of the motor vehicle which access sensor units of the motor vehicle,
ascertain control commands to control the motor vehicle by the vehicle control unit to implement the requests,
ascertain a respective feasibility of the control commands based on predetermined verification criteria with respect to contradictions of each of the control commands with each other and a practicability of each of the control commands, and
ascertain a control specification for the vehicle control unit based on the feasibilities of the control commands and predetermined decision criteria,

wherein the vehicle control unit is configured to control the motor vehicle according to the control specification.

10. The control system according to claim 9 , wherein the conflict checking unit is configured to ascertain the respective feasibility of the control commands by:
determining whether contradictive control commands exist due to a plurality of requests of one of the evaluation units and/or due to target conflicts of control commands based on requests of different evaluation units, and/or
determining the practicability of each of the control commands based on current road conditions, traffic conditions, and/or a current travel route of the motor vehicle.

11. The control system according to claim 9 , wherein the conflict checking unit is configured to ascertain the control specification by estimating advantages which are to be expected upon performing respective control commands, the estimating advantages including estimating an expected improvement to the working conditions of the evaluation units which access the sensor units.

12. The control system according to claim 11 , wherein the conflict checking unit is configured to ascertain the control specification by estimating disadvantages which are to be expected upon performing respective control commands.

13. The control system according to claim 12 , wherein the conflict checking unit is configured to ascertain the control specification by relating the advantages and disadvantages to each other based on predetermined evaluation rules.

14. The control system according to claim 13 , wherein
the predetermined evaluation rules include a ranking of the predetermined decision criteria, and the predetermined decision criteria includes:
a safety risk for occupants of the motor vehicle,
a safety risk for motor vehicles, persons, and/or objects in an environment of the motor vehicle,
a comfort measure for the occupants of the motor vehicle,
a gain in time for the occupants of the motor vehicle,
an energy saving of the motor vehicle,
an emission reduction of the motor vehicle,
an improvement of the working conditions of the respective evaluation units,
an effort associated with control of the control commands for the vehicle control unit, or
an effect of the control of the motor vehicle with respect to a current travel route of the motor vehicle.

15. A motor vehicle, comprising:
sensor units;
evaluation units configured to access the sensor units; and
a control system including:
a vehicle control unit, and
a conflict checking unit configured to:
receive requests from the evaluation units relating to a control of the motor vehicle for improving working conditions of the evaluation units,
ascertain control commands to control the motor vehicle by the vehicle control unit to implement the requests,
ascertain a respective feasibility of the control commands based on predetermined verification criteria with respect to contradictions of each of the control commands with each other and a practicability of each of the control commands, and
ascertain a control s
