Abstract

The invention relates to a control system for a motor vehicle, including a first electronic control system for controlling a first load current of a first load and a second electronic control system for controlling a second load current of a second load. The first electronic control system and the second electronic control system are arranged at a distance from one another and are connected to one another. At least the second electronic control system has a sleep mode and an operating mode, and only the first electronic control system can switch the second electronic control system from the sleep mode into the operating mode.

Claims

1. A control system for a motor vehicle, comprising

a first electronic control system for controlling a first load current of a first load;

and

a second electronic control system for controlling a second load current of a second load,

wherein the first electronic control system and the second electronic control system are arranged at a distance from one another and are connected to one another,

wherein at least the second electronic control system has a sleep mode and an operating mode, and

wherein only the first electronic control system is adapted to switch the second electronic control system from the sleep mode into the operating mode.

2. The control system according to claim 1, further comprising a switching device that is configured to switch off a power supply of the second electronic control system in the sleep mode.

3. The control system according to claim 2, wherein the first electronic control system is connected to the switching device in order to switch on the power supply of the second electronic control system for the operating mode.

4. The control system according to claim 1, wherein only the second electronic control system is adapted to switch itself into the sleep mode.

5. The control system according to claim 1, wherein the first electronic control system is adapted to disconnect a load line for supplying power to the second load.

6. The control system according to claim 1, wherein the first electronic control system comprises a bus node, and wherein the first electronic control system communicates with a central electronic system via a bus connection.

7. The control system according to claim 6, wherein the second electronic control system is configured to be switched from the sleep mode into the operating mode by the central electronic system via the bus connection and via the first electronic control system.

8. The control system according to claim 1, wherein a plurality of functions of the second load are adapted to be controlled by the first electronic control system via a bidirectional interface between the first electronic control system and the second electronic control system.

9. The control system according to claim 1, wherein, during the operating mode, the operating mode can be obtained through a logic OR operation by the first electronic control system or by the second electronic control system.

10. The control system according to claim 1,

wherein the first electronic control system is arranged in a front vehicle door and is connected to a window lifter of the front vehicle door as a first load, and

wherein the second electronic control system is arranged in a rear vehicle door and is connected to a window lifter of the rear vehicle door as a second load.
