ABSTRACT:
A vehicle control system having plurality of control units, as well as sensors and actuators having a comparatively high degree of importance in terms of control by these control units, which are separately connected to first and second transmission lines. Sensors and actuators having a comparatively low degree of importance are assigned to the second transmission line. The outputs from the comparatively important sensors enter the respective control units directly via the first transmission line. A back-up program for backing up one control unit in case of failure is stored beforehand in another control unit. If the control unit fails, the other control unit performs back-up control to take over its tasks.
