    • The control circuit comprises a memory circuit and a calculation circuit. The control circuit derives wheel speed from a detector, and delivers a brake release signal and a braking signal to a hydraulic brake system of a vehicle after the occurrence of a skid. A memory circuit beforehand memorizes optimum control patterns shown by the function of time and vehicle velocity corresponding to slip rate between wheel and road surfaces. A calculation circuit determines a slip rate by referring to wheel speed, and selects an optimum control pattern corresponding to the calculated slip rate from the memory circuit. Then, the calculation circuit controls the hydraulic brake system in accordance with the selected optimum pattern. When the slip rate becomes 50% after the panic braking, the calculation circuit releases the oil pressure of the hydraulic brake system and, when the slip rate becomes 20% after the panic braking, the calculation circuit outputs the braking signal to the hyraulic brake system.
    • 控制电路包括存储器电路和计算电路。 控制电路从检测器获得车轮速度,并且在发生滑行之后将制动释放信号和制动信号传送到车辆的液压制动系统。 存储器电路预先存储与车轮和路面之间的滑移率相对应的时间和车速函数所示的最佳控制模式。 计算电路通过参照车轮速度来确定滑移率,并从存储器电路中选择与计算出的滑移率对应的最佳控制模式。 然后,计算电路根据所选择的最佳模式来控制液压制动系统。 当紧急制动之后的滑差率变为50%时,计算电路释放液压制动系统的油压,并且当紧急制动之后的滑移率变为20%时,计算电路将制动信号输出到液压制动系统 。
