    • In the vehicle equipped with an ABS, a control system for reducing stopping distance in an abrupt braking operation and a method thereof includes an idle sensor for detecting an operating state of an accelerator pedal; a brake sensor for detecting an operating state of a brake pedal; a brake operation sensor for detecting an angle change of a brake pedal to output an electric signal corresponding thereto; an engine RPM sensor for detecting a rotation number of a crank gear to output an electric signal corresponding thereto, the sensor being equipped on an engine crank shaft and rotated by driving engine; a transmission control unit which when a power source is applied to the vehicle and the idle switch and the brake switch is worked, detects the angle change per hour of the brake pedal and then if the brake angle change is over the predetermined one, determines that as an abrupt braking state, and further detects the shift range set up by the operation of the shift lever as well as the current shift stage in accordance with the current shift range, and thus down-shifts into a lower stage than the current running shift stage; and an hydraulic pressure control valve for applying an hydraulic pressure to shift gear devices corresponding to shift signals output from the transmission control unit; and thereby when the driver abruptly pedals the brake, performs forceful down-shifting into a lower stage than the current shift stage.
    • 在配备有ABS的车辆中,用于减少突然制动操作中的停止距离的控制系统及其方法包括用于检测加速器踏板的操作状态的怠速传感器; 用于检测制动踏板的操作状态的制动传感器; 制动操作传感器,用于检测制动踏板的角度变化以输出与其对应的电信号; 发动机RPM传感器,用于检测曲柄齿轮的转数以输出与其对应的电信号,所述传感器装备在发动机曲轴上并通过驱动发动机旋转; 传动控制单元,当将电源施加到车辆并且怠速开关和制动开关被加工时,检测制动踏板每小时的角度变化,然后如果制动器角度变化超过预定的角度,则确定 作为突然制动状态,并且还根据当前的换档范围来检测由变速杆的动作以及当前的换档阶段而设定的换档范围,并且因此下降到比当前的行驶换档 阶段; 以及液压控制阀,用于对应于从所述变速器控制单元输出的换挡信号对变速齿轮装置施加液压; 从而当驾驶员突然踏起制动时,进行有力的向下移动到比当前变速级更低的阶段。
