Patent ID: 6945611

Claim:
A braking system for vehicles equipped with an ABS system or an antiskid protection system, comprising: rotational wheel speed sensors for sensing rotational wheel speed and providing rotational wheel speed signals; an arithmetic unit which has at least two channels for the separate calculation of at least a first and a second reference speed approximating the actual vehicle speed from the rotational wheel speed signals and for generating control signals for antilock valves based on the reference speeds (V ref1 , V ref2 ), a first portion of the antilock valves for a first group of wheels being assigned to a first channel, and a second portion of the antilock valves for a second group of wheels being assigned to a second channel; at least first and second rotational wheel speed sensors for wheels of the first and second groups, respectively being assigned only to the first channel for the first reference speed calculation; at least third and fourth rotational wheel speed sensors for wheels of the first and second groups respectively being assigned only to the second channel for the second reference speed calculations; the first and third rotational wheel speed sensors being assigned to the first channel for generating control signals for the first portion of the antilock valves for the first group of wheels; and the second and fourth rotational wheel speed sensors being assigned to the second channel for generating control signals for the second portion of the antilock valves for the second group of wheels.
