The invention discloses an electric automobile braking priority method. The method comprises the steps that S001 a control device of an electric automobile detects whether a brake pedal generates a brake signal or not in real time so as to judge whether the brake pedal is stepped on or not, if the brake pedal is stepped on, the brake signal is transmitted to the control device, and the step S002 is executed; if the brake pedal is not stepped down, no brake signal is transmitted to the control device, and the step S003 is executed; S002 the control device interrupts an accelerator signal, so that after the accelerator pedal is stepped down, the accelerator signal cannot be generated and transmitted to the control device, that is, stepping-down of the accelerator pedal is invalid, the driving motor cannot be controlled to accelerate, and the step S001 is executed again; and S003 the control device recovers the accelerator signal, the accelerator signal can be generated after the accelerator pedal is stepped down, the accelerator signal can be transmitted to the control device, in other words, after the accelerator pedal is stepped down, the driving motor can be controlled to accelerate, the control device is switched into normal working condition control, the electric automobile is in a normal driving state, and the step S001 is executed again.

    本发明公开一种电动汽车刹车优先方法,其包括以下步骤:S001:电动汽车的控制装置实时检测制动踏板是否产生刹车制动信号,以判断是否踩下制动踏板,如果制动踏板被踩下,则有刹车制动信号传送到控制装置,进入步骤S002;如果制动踏板没有被踩下,则无刹车制动信号传送到控制装置,进入步骤S003;S002:控制装置中断油门信号,使加速踏板被踩下后,也不会产生油门信号传送给控制装置,即踩下加速踏板无效,无法控制驱动电机加速,返回至步骤S001;S003:控制装置恢复油门信号,使加速踏板被踩下后,会产生油门信号,且油门信号会传送给控制装置,即踩下加速踏板后,可控制驱动电机加速,控制装置转入正常工况控制,电动汽车处于正常驾驶状态,并返回至步骤S001。
