ABSTRACT:
An antilock control device includes a brake operation detecting unit, a wheel speed detecting unit, a control unit which detects a request for antilock control on the basis of a brake operation signal from the brake operation detecting unit and wheel speed signals from the wheel speed detecting unit and outputs a brake pressure control signal, and a brake pressure control circuit operative in response to said brake pressure control signal. The control unit has a judging function for detecting a request for starting antilock control while the vehicle speed is between a relatively low first predetermined speed and a higher second predetermined speed and the brake operation signal is OFF and a function of deciding whether to permit or prohibit the execution of antilock control. More specifically, if no request for starting antilock is detected, permission to execute antilock control is given while the vehicle speed is higher than the first predetermined value. If a request for starting antilock control is detected, the execution of antilock control is prohibited while the vehicle speed is between the first and second predetermined values. In another arrangement, even if such a request is detected, permission to execute antilock control is given while the vehicle speed is between the first and second predetermined speeds, provided the brake operation signal is ON.
