发明名称 Anti-skid or anti-slip braking system that suppresses interference signals at a mains frequency
摘要 The method of controlling a motor vehicle braking system to prevent wheel slip or skidding includes generating wheel speed signals indicative of wheel speeds of each of at least two wheels; determining the wheel speeds from each wheel speed signal; determining a vehicle reference speed from one of the wheel speeds; determining whether or not the vehicle reference speed is within a predetermined speed range of 47 to 63 Hz, during which interference signals from a vehicle power source at about a mains frequency are generated that produce false wheel speed signals and controlling the motor vehicle braking system according to a special ABS control method when the vehicle reference speed is within the predetermined speed range. In the special ABS control method the interference signals are accounted for so that improper activation of or influence on the braking system due to the interference signals is prevented. In a preferred embodiment of the method an auxiliary reference speed is determined from a wheel speed of another wheel, the vehicle reference speed is negatively adjusted when the vehicle reference speed is within the predetermined speed range and the nondriven wheels are controlled according to the auxiliary reference speed until the vehicle reference speed falls below a predetermined speed threshold when the vehicle reference speed is within the predetermined speed range.
