Abstract
In an acceleration slip control system for a motor vehicle, (a) a device for detecting the temperature of brake fluid at the end of an acceleration slip control or, (b) a device for detecting the hydraulic pressure of the wheel cylinder at the end of the acceleration slip control, is installed in order that a predetermined time period for which a releasing device for reducing the hydraulic pressure of a wheel cylinder is released to open a fluid passage leading to a reservoir, may be made variable in accordance with the detected brake fluid temperature or the hydraulic pressure. Alternatively, (c) a device for detecting the hydraulic pressure of the wheel cylinder in real time is installed in order that the releasing means for reducing the hydraulic pressure of the wheel cylinder may be released until the hydraulic pressure of the wheel cylinder becomes lower than a predetermined value. Thus, when the acceleration slip control has ended, the control system can cope with subsequent braking more quickly while protecting a master cylinder and preventing the production of noise.
