An induction motor control system (10) for electric vehicles having a DC power supply (12), an inverter (14), an induction motor (16), and a clamping unit (26). The clamping unit (26) applies a clamping value iq_clamp to a real torque current command iq*. The clamping value iq_clamp is calculated in a maximum torque current calculation unit 28 and is based on predetermined maximum settings for the motor power Pmax and torque Tmax. The clamping value iq_clamp is applied such that the torque current command iq* cannot exceed the clamping value iq_clamp, whereby the induction motor produces 16 output power Pout and torque Tout that is always less than the predetermined maximum settings, Pmax and Tmax.
