A torque control method and torque control system for an electric drive system are provided. The method includes: obtaining a charge cut-off voltage and a discharge cut-off voltage of the high-voltage battery; setting an allowable charge lower limit value and an allowable discharge upper limit value; setting a dynamic target voltage value when the actual voltage of the high-voltage battery is greater than or equal to the allowable charge lower limit value or is smaller than or equal to the allowable discharge upper limit value; calculating a target torque value based on the actual voltage of the high-voltage battery and the dynamic target voltage value; setting an available torque limit value of the electric drive system based on the target torque value and a comparison result of the actual voltage of the high-voltage battery with each of the allowable charge lower limit value and the allowable discharge upper limit value, and controlling a torque output of the motor based on the available torque limit value.
