Abstract

The invention relates to a braking and steering system for a vehicle which provides at least fail-safe braking and steering. In a fault-tolerant, preferably redundant, computing unit, a desired braking effect is determined at least for each wheel of the vehicle, and a desired steering effect is determined for each wheel with a steering function, in each case in response to sensor signals. The braking function and the steering function for the wheels are regulated or controlled by means of adjusting systems on the basis of the determined desired braking effect and desired steering effect. The adjusting system for the braking function contains a service brake and that for the steering function additionally contains a steering adjuster. A fault-tolerant communication device connects the adjusting systems to the computing unit. The energy supply of the computing unit and of the adjusting systems is designed with fault tolerance.
