A control system for a vehicle having a plurality of signal processing levels and actuators, in particular for brake, steering, engine and gearbox, for converting actuation signals and a method for controlling a vehicle. The system employs the following levels: an input level for continuous stipulations or an input level for discrete stipulations and an automation level for generating setpoint value signals, a predictive level and/or a reactive level for correcting the setpoint value signals, a coordination level for converting the set point value signals into actuation signals, and an execution level with the actuators. The actuators are connected to one another and to the coordination level by a fault-tolerant, redundant and bidirectional databus. Measures for redundant signal processing are taken, and data is transmitted in a fault-tolerant, redundant and bidirectional fashion.
