The invention discloses a control method for preventing abnormal acceleration of a vehicle caused by an accelerator pedal fault. The control method comprises the following steps: pre-determining an upper limit threshold value and a lower limit threshold value of an accelerator pedal opening value corresponding to each safety reference voltage value; the currently obtained accelerator pedal opening value is compared with the upper threshold value of the accelerator pedal opening value corresponding to the currently obtained safety reference voltage value, and if the currently obtained accelerator pedal opening value is higher than the upper threshold value of the accelerator pedal opening value corresponding to the currently obtained safety reference voltage value, the accelerator pedal opening value is determined to be the accelerator pedal opening value. If yes, torque output of the motor is controlled according to the lower limit threshold value of the accelerator pedal opening value corresponding to the currently obtained safety reference voltage value. Under the condition that the current safety reference voltage value and the current accelerator pedal opening degree value are obtained, the current accelerator pedal opening degree value is verified according to the upper limit threshold value of the accelerator pedal opening degree value corresponding to the safety reference voltage value, and the driving risk caused by accidental acceleration of the vehicle can be prevented.
本发明公开了一种防止因加速踏板故障而导致车辆异常加速的控制方法,预先确定各安全参考电压值对应的加速踏板开度值的上限阈值和下限阈值;将当前获得的加速踏板开度值与当前获得的安全参考电压值所对应的加速踏板开度值的上限阈值相比较,若当前获得的加速踏板开度值高于当前获得的安全参考电压值所对应的加速踏板开度值的上限阈值,则以当前获得的安全参考电压值所对应的加速踏板开度值的下限阈值控制电机的扭矩输出。本发明在获得当前的安全参考电压值和当前的加速踏板开度值的情况下,以安全参考电压值对应的加速踏板开度值的上限阈值对当前的加速踏板开度值进行校验,可防止车辆意外加速带来的驾驶风险。
