Abstract

Driver-related electrical adjusting components in motor vehicles are regulated. An operator signal is generated based on a user actuating operator elements, to affect a desired movement of a vehicle component. The operator signal is processed in a control unit. An effect of the operator signal on movement of the vehicle component is regulated as a function of vehicle operating state signals so as to prevent the vehicle component from moving into a safety-critical position.

Claims

1. A method for regulating a motor vehicle adjusting mechanism for a vehicle component, comprising:

receiving an occupant-initiated signal that is generated during movement of the motor vehicle when an operating element of the adjusting mechanism is activated to cause movement within a vehicle passenger compartment and associated with the adjusting mechanism; and

processing the occupant-initiated signal in a control unit to reduce or prevent movement of the vehicle component initiated by a vehicle occupant into a safety critical position only during the movement of the motor vehicle upon occurrence of one of expiration of a time interval defined as a function of vehicle speed and beginning with a previous modification of the occupant-initiated signal, exceeding of a maximum vehicle component speed determined as a function of vehicle speed, and exceeding of a vehicle component movement range which is less than a full range of vehicle component motion determined as a function of vehicle speed.

2. The method of claim 1, wherein the processing comprises:

making a movement of the vehicle component perceptible to the vehicle occupant.

3. The method of claim 1, wherein the processing comprises:

regulating strength of the occupant-initiated signal on movement of the vehicle component also as a function of vehicle occupant parameters so as to maintain a function of motor vehicle passive safety devices.

4. The method of claim 1, wherein the previous modification is a previous actuation of the operating element.

5. The method of claim 4, wherein the time interval is decreased monotonically as vehicle speed increases.

6. The method of claim 1, wherein a speed of the vehicle component movement is limited to a defined maximum speed.

7. The method of claim 6, wherein a maximum movement speed of the vehicle component is decreased monotonically as vehicle speed increases.

8. The method of claim 1, wherein the processing comprises:

limiting the movement of the vehicle component to a reduced range of movement that is less than a full range of movement of the vehicle component.

9. The method of claim 8, wherein the reduced range includes a position of the vehicle component at an initialization time.

10. The method of claim 9, wherein the initialization time includes at least one of:

a time at which a battery voltage is applied to a vehicle terminal;

a time at which a motor of the motor vehicle starts;

a time at which a relative or absolute vehicle speed threshold is exceeded;

a time at which a relative or absolute vehicle speed threshold is not reached; and

a time at which a time interval expires.

11. The method of claim 8, wherein the reduced range is decreased monotonically as vehicle speed increases.

12. The method of claim 1, further comprising:

providing occupant feedback in response to an actuation of the operating element.

13. A control system for regulating an adjusting mechanism for a vehicle component in a motor vehicle, comprising:

an input for receiving an occupant-initiated signal, wherein the signal is generated during movement of the motor vehicle when an operator element of the adjusting mechanism is activated to cause a desired movement of the vehicle component located within a vehicle passenger compartment area associated with the adjusting mechanism; and

a module that processes the signal for regulating behavior of the adjusting mechanism so as to prevent or reduce the desired movement of the vehicle component initiated by the vehicle occupant into a safety-critical position only during movement of the motor vehicle upon occurrence of one of expiration of a time interval defined as a function of vehicle speed and beginning with a previous modification of the occupant-initiated signal, exceeding of a maximum vehicle component speed determined as a function of vehicle speed, and exceeding of a vehicle component movement range which is less than a full range of vehicle component motion determined as a function of vehicle speed.

14. The system of claim 13, wherein the processing module allows a movement of the vehicle component that is perceptible to the occupant.

15. The system of claim 13, wherein the processing module regulates strength of the occupant-initiated signal on movement of the vehicle component also as a function of occupant parameters so as to maintain a function of motor vehicle passive safety devices.

16. The system of claim 13, wherein the previous modification is a previous actuation of the operating element.

17. The system of claim 13, wherein the module limits a speed of the vehicle component movement.

18. The system of claim 13, wherein the module limits the movement of the vehicle component to a reduced range of movement that is less than a full range of movement of the vehicle component.

19. The system of claim 13, wherein the processing module provides feedback to the occupant as a reaction to an actuation of the operator element.

20. A regulating system in a motor vehicle, comprising:

an electrical adjusting mechanism for adjusting a vehicle component located within a passenger compartment and having an associated operator element; and

a control unit comprising;

an input for receiving a signal that is generated when a vehicle occupant actuates the operator element to cause a desired movement of the vehicle component; and

logic for regulating the adjusting mechanism so as to reduce or prevent the desired movement initiated by the vehicle occupant into a safety-critical position only during movement of the motor vehicle upon occurrence of one of expiration of a time interval defined as a function of vehicle speed and beginning with a previous modification of the occupant-initiated signal, exceeding of a maximum vehicle component speed determined as a function of vehicle speed being exceeded, and exceeding of a vehicle component movement range less than a full range of vehicle component motion determined as a function of vehicle speed.
