Abstract: A method of controlling an accelerator of a four-wheel drive electric vehicle comprises the steps of controlling power output of the vehicle by a sum of an output torque of a main drive motor and an output torque an auxiliary drive motor with the output torque of the main drive motor being determined by a position of the accelerator pedal. The output torque T0 of the auxiliary drive motor is determined by: obtaining a torque calculation factor GainAccSum that a cumulative value of the acceleration GainAcc of the accelerator pedal; determining a maximum output torque T of the auxiliary drive motor at a current speed of the vehicle; and calculating the output torque T0 of the auxiliary drive motor varying between 0 and T based on the torque calculation factor GainAccSum and the maximum output torque T of the auxiliary drive motor at the current speed of the vehicle.
