The invention discloses a safety control method and system for preventing an accelerator from being used as a brake by mistake. The control method comprises the steps that the force threshold value of the force of an accelerator pedal is preset; presetting a speed threshold value of the accelerator pedal position stroke; when the force of the accelerator pedal reaches the force threshold value, a force signal is sent out; when the position change speed reaches the speed threshold value, a speed signal is sent out; generating a brake enable signal according to the received speed signal and force signal; when the brake control signal is received, the engine stops supplying oil, and the auxiliary brake mechanism controls the vehicle to brake; the brake pedal is treaded, engine oil supply is relieved, and the auxiliary brake mechanism controls the vehicle to brake; according to the invention, when a driver mistakenly steps on the accelerator as the brake, the ESP releases a signal and controls the brake system to execute the brake instruction, so that the safety of passengers caused by mistakenly stepping on the accelerator as the brake is improved.
本发明公开了一种防止误把油门当刹车使用的安全控制方法及系统,控制方法包括:预设油门踏板力度的力度阈值;预设油门踏板位置行程的速度阈值;当所述油门踏板力度达到所述力度阈值,发出力度信号;并且所述位置变化速度达到所述速度阈值,发出速度信号;根据接收到速度信号和力度信号,生成制动使能信号;接收到制动控制信号,发动机停止供油并且辅助刹车机构控制车辆刹车;踩踏制动踏板,解除发动机停止供油并且辅助刹车机构控制车辆刹车;本发明可以实现当司机误把油门当刹车踩下后,ESP释放信号,控制刹车系统执行刹车指令,提高乘客因误踩油门当刹车的安全性。
