一种信号处理电路，其提供适于控制流体控制制动致动机构中的制动压力的施加的控制信号。对幅值与车轮速度成比例的输入信号进行微分，以产生与加速度和减速度成比例的信号。当超过预定的减速度阈值时，产生第一输出信号。当同时超过减速度和速度阈值时，产生第二输出信号。保持第二输出信号，直到速度信号超过在加速期间仅随加速度变化的可变参考阈值。
A signal processing circuit provides control signals suitable for controlling the application of braking pressure in a fluid-control brake actuating mechanism. An input signal whose amplitude is proportional to wheel speed is differentiated to yield a signal proportional to acceleration and deceleration. A first output signal is generated when a predetermined deceleration threshold is exceeded. A second output signal is generated when both a deceleration and a velocity threshold are simultaneously exceeded. The second output signal is maintained until the velocity signal exceeds a variable reference threshold which varies with acceleration alone during acceleration.
