摘要： An anti-skid control system for an automotive vehicle is provided with an actuator which is disposed in a hydraulic circuit between a pressure generator and a wheel brake cylinder. The actuator is arranged to control the hydraulic braking pressure applied to the wheel brake cylinder. In response to a wheel speed detected by a wheel speed detector, it is determined in an electronic control unit whether a condition for decreasing the braking pressure is effected. When this condition is effected, the decrease mode is provided in the control unit. When a predetermined period of time lapses after the decrease mode is initiated, the decrease mode is turned to a pressure control mode for applying the braking pressure to prevent the road wheel from being locked. When the condition is not effected during the predetermined period of time after the decrease mode is initiated, the decrease mode is turned to a direct supply mode for directly communicating the pressure generator with the wheel brake cylinder. Consequently, the lack of braking force caused by the delay of timing for decreasing the hydraulic braking pressure due to an erroneous detection of a locking condition of the road wheel on a rough road is effectively prevented.

摘要： The invention is directed to an anti-skid control system for controlling a braking force applied to a road wheel with a hydraulic braking pressure supplied to a wheel brake cylinder through a pressure control valve controlled by an electronic controller. On the basis of a wheel speed of the road wheel detected by a wheel speed sensor, the controller calculates an estimated vehicle speed and sets a reference speed on the basis thereof. In the controller, the wheel speed is compared with the reference speed, and in response to a result of comparison the hydraulic pressure supplied to the wheel brake cylinder is controlled by the pressure control valve. Through an adjustment by the controller, the hydraulic braking pressure is decreased in response to a change of difference between the wheel speed and the estimated vehicle speed for a certain period of time. The controller may be arranged to calculate an integrated value of the difference between the wheel speed and the estimated vehicle speed, to compare a value which is obtained by subtracting the integrated value from the wheel speed, with the reference speed, and to decrease the hydraulic pressure in the wheel brake cylinder in response to the result of comparison.
