A drive force control system for an electric vehicle configured to prevent a temperature rise in a motor to a restrictive temperature, and to ensure running stability of the electric vehicle when the temperature of the motor reaches the restrictive temperature. The control system comprises: an upper limit torque determiner that employs a torque of the first motor as an upper limit torque when a temperature of the first motor reaches a first predetermined temperature, in a case that the temperature of the first motor is higher than a first predetermined temperature but lower than a first restrictive temperature; a restrictive torque determiner that employs a first limit torque as the upper limit torque of the first motor, in a case that the temperature of the first motor reaches the first restrictive temperature; and a target torque determiner configured to determine a torque of another prime mover based on the upper limit torque of the first motor and a target torque ratio between the front wheel and the rear wheel.
