Abstract
An anti-lock control system for motor vehicles is designed to have its computed vehicle speed modified as the motor vehicle is braked. In this invention, the computed vehicle speed persists along a reference deceleration gradient line representing a predetermined acceleration follow-up limit measured with respect to the wheel speed for a predetermined period of time from a point of time when the deceleration of the computed vehicle speed reaches the reference deceleration gradient line for the first time after the motor vehicle was braked. Thereafter, the computed vehicle speed is modified to follow a deceleration gradient line with a gradient that is gentler than that of the reference deceleration gradient line, until a threshold speed is reached, which is lower by a predetermined amount than and follows the computed vehicle speed with such a speed difference.
