ABSTRACT:
An apparatus for controlling running of a motor vehicle by measuring respective values of acceleration of the vehicle wheels, includes a digital low-pass filter for obtaining acceleration values by excluding high-frequency noise components of successive values of instantaneous acceleration which are obtained for each wheel at successive sampling intervals. Filter parameters such as the cut-off frequency can be controlled in accordance with the current operating conditions of the respective wheels, such as wheel velocity, to thereby provide optimum filter operation and hence substantially improved accuracy for the derived values of acceleration.
