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
