Abstract:
A method of controlling a motor vehicle braking system of a motor vehicle to prevent wheel slip or skidding, said method comprising the steps of:a) generating wheel speed signals indicative of wheel speeds of each of at least two wheels of the motor vehicle;b) determining the wheel speeds from each of the wheel speed signals;c) determining a vehicle reference speed from one of the wheel speeds determined in step b) for one of the at least two wheels;d) determining whether or not the vehicle reference speed ascertained in step c) is within a predetermined speed range of 47 to 63 Hz, during which interference signals from a vehicle power source at mains frequency are generated that produce false wheel speed signals; ande) controlling the motor vehicle braking system according to an ABS control method when the vehicle reference speed is within the predetermined speed range according to step d), the ABS control method comprising a control process in which the interference signals are accounted for, whereby improper activation of or influence on the braking system due to the interference signals is prevented.
