Abstract

This device uses in addition to the usual wheel pulse transmitters (RA1, RA2) an inertial accelerometer (BM). When slip occurs during acceleration and deceleration of the vehicle, the measurement of the inertial accelerometer (BM) is used instead of the wheel pulse sequence (b) as a basis for the distance and speed measurement. This simple device can replace expensive distance measuring systems which operate, for example, optically or with Doppler radar, up to a certain degree.
