摘要： In an anti-lock control system for a motor vehicle, the design is made such that such that computed vehicle speed is prevented from remarkably departing from real vehicle speed as driving wheel slips before anti-lock control is started, thereby preventing occurrence of non-braking condition when anti-lock control is started. To this end, the manner in which the computed vehicle speed is computed, is changed between during braking operation (when anti-lock control is being effected) and non-braking operation (when no anti-lock control is being effected).

摘要： An anti-skid control system for motor vehicles is provided wherein when the time period from when the wheel velocity being decreased reaches a second reference velocity to a low peak of the wheel velocity at which the reduction of the brake pressure is to be stopped, is longer than a predetermined time period, the reduction of the brake pressure is continued until the wheel velocity is increased up to a first reference velocity which is higher than the second reference velocity. In this way, even if the wheel velocity drops sharply because the coefficient of friction of the road surface suddenly changes from high to low, the wheel velocity recovers so that the wheels of the motor vehicle are prevented from locking early.

摘要： 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.

摘要： In an anti-lock control system for motor vehicles, the design is made such that when the motor vehicle is running on a rough road, reduction of the brake hydraulic pressure can be prevented from being started early by detecting that the motor vehicle is running on the rough road, and such that any adverse effects can be avoided which tend to be produced in the case where a device for coping with the rough road is applied when the road surface on which the motor vehicle is running is a low-.mu. road surface or when the motor vehicle is running with a low speed.
