An electric automobile safety control system and method comprise a brake liquid storage tank device, the brake liquid storage tank device is connected with a brake disc at a hub through a hydraulic pipeline, a pipeline pressure sensor is arranged on the hydraulic pipeline, a current sensor is arranged at a motor high-pressure system, and a filter blocking pressure sensor is arranged at a filter. And monitoring values of the pipeline pressure sensor, the current sensor and the filter blockage pressure sensor are sent to a brake reliability device (BSPD). A brake pedal travel signal, a brake pipeline pressure signal, a high-voltage current signal and a filter blockage pressure signal are received through a brake reliability device BSPD, and the actual situation of current brake is judged through logic of all the signals, so that the situation that a protection relay is triggered by mistake is prevented; the phenomenon that the electric vehicle loses power too early or brake fails during braking is avoided, and under the condition that extra devices are not added, the brake reliability device BSPD works more reliably only through multiple received signals and logic judgment.

    电动汽车安全控制系统及方法,包括制动储液罐装置,制动储液罐装置通过液压管路与轮毂处的制动刹车盘连接,在液压管路上设有管路压力传感器,电动机高压系统处设有电流传感器,过滤器处设有过滤器堵塞压力传感器,管路压力传感器、电流传感器和过滤器堵塞压力传感器的监测数值送至制动可靠性装置BSPD处。通过制动可靠性装置BSPD接收制动踏板行程信号、制动管路压力信号、高压电流信号以及过滤器堵塞压力信号,并通过各信号的逻辑判断当前刹车的真实情况,以防止出现误触发保护继电器的情况,避免出现电动车刹车时过早失去动力或者“刹车失灵”的现象,在不增加额外的器件的情况下,仅通过多接收信号及逻辑判断,即让制动可靠性装置BSPD更加可靠的工作。
