Abstract
A control system for an electric vehicle has a vehicle speed calculation section that calculates a speed of the electric vehicle and a control unit that controls an inverter of an electric motor to provide road wheels with a predetermined reference torque in accordance with a manipulated value of an accelerator pedal, wherein the unit has a reference torque correction section that changes the reference torque from an original value and then returns the changed reference torque to the original value when a calculated speed of the electric vehicle is in a given speed range.
