Abstract

A method and a device for operating a motor vehicle including auxiliary systems which enable a coordinated and less costly switch-off or performance reduction strategy for the auxiliary systems. At least one switch-off condition is predefined for multiple auxiliary systems as a function of an operating state of the motor vehicle. The presence of the at least one switch-off condition for the auxiliary systems is checked centrally.

Claims

1. A method for operating a motor vehicle including auxiliary systems, the method comprising:

predefining at least one switch-off condition for a plurality of auxiliary systems as a function of an operating state of the motor vehicle; and

checking centrally a presence of the at least one switch-off condition for the auxiliary systems.

2. The method according to claim 1, wherein the presence of the at least one switch-off condition is checked in a control center outside the auxiliary systems.

3. The method according to claim 1, wherein the presence of the at least one switch-off condition is checked in one of (a) precisely one of the auxiliary systems and (b) an auxiliary system module assigned to one of the auxiliary systems.

4. The method according to claim 1, further comprising, in the presence of the at least one switch-off condition, centrally transmitting one of a switch-off signal and a signal for performance reduction to the auxiliary systems to be one of (a) switched off and (b) reduced in their performance.

5. The method according to claim 1, further comprising, in the presence of the at least one switch-off condition, one of (a) switching off and (b) reducing in their performance the auxiliary systems to be one of (a) switched off and (b) reduced in their performance, in a coordinated manner.

6. The method according to claim 5, wherein the auxiliary systems are one of (a) switched off and (b) reduced in their performance in a predefined sequence.

7. The method according to claim 1, wherein in one of (a) at least one of the auxiliary systems and (b) an auxiliary system module assigned to one of the auxiliary systems, a switch-off condition is checked which is specific for the auxiliary system.

8. The method according to claim 1, wherein the at least one switch-off condition includes a presence of at least one of a full-load operating state, an acceleration operating state, a starting state, and a state of a vehicle system voltage below a predefined threshold value.

9. The method according to claim 1, wherein the auxiliary systems include at least one of a generator, a heater, an air-conditioner compressor, a fan, and a power-steering pump.

10. A device for operating a motor vehicle including auxiliary systems, at least one switch-off condition being predefined for a plurality of auxiliary systems as a function of an operating state of the motor vehicle, the device comprising:

means for centrally checking a presence of the at least one switch-off condition for the auxiliary systems.
