Abstract

A process and device for an open-loop control and a closed loop control of the brake system of a vehicle, wherein brake pedal actuation is measured by at least two, preferably diversitary, measuring devices, and the driver's braking command is independently obtained and further processed from at least two actuation signals. A third measuring device, measuring brake pedal actuation, is provided for locating errors. The control device effecting the open-loop control and the closed-loop control of the brake system comprises at least two microcomputers with the signals of the at least two measuring devices being supplied to both, while the signal of the monitoring device is only supplied to one microcomputer.
