The invention discloses an arbitration method and system for the opening degree of an automobile accelerator pedal. Adjusting the upper and lower limits of the opening degree of the accelerator pedal according to the fault of the accelerator pedal when the accelerator pedal sensor has the fault; and determining the final opening degree of the accelerator pedal according to the adjusted upper and lower limits of the opening degree of the accelerator pedal and the current opening degree of the accelerator pedal. According to the method, before the vehicle torque is calculated, various fault states of the accelerator pedal are judged, the upper limit value and the lower limit value of arbitration in different states are defined, when the calculated accelerator pedal opening degree exceeds the upper limit value and the lower limit value of arbitration, the safe AP opening degree value is output to be used for calculating the driving torque, and the reliability of driving safety is improved.
本发明公开了一种汽车加速踏板开度的仲裁方法和系统。当加速踏板传感器存在故障,根据加速踏板的故障调整加速踏板开度的上下限;根据所述调整后的加速踏板开度的上下限和当前加速踏板的开度确定加速踏板的最终开度。本发明在车辆扭矩计算前增加了对加速踏板的各种故障状态进行判断并定义不同状态下的仲裁的上下限值,在计算出的加速踏板开度超出仲裁的上下限时,输出较为安全的AP开度值用于驱动扭矩的计算,提高了对行车安全的可靠性。
