An automotive vehicle equipped with wheels connected to induction motors through transmissions is provided with a speed control apparatus connected to the induction motors for adjusting the speed of rotation or RPM of the wheels. The speed control apparatus has a voltage supply and a converter connected to this supply and to at least some of the motors to supply the latter with a voltage changeable in magnitude and frequency. At least one voltage control member is connected between at least one of the motors and the converter. A control device actuable when the vehicle travels along a curved path is connected to the voltage control member for adjusting the RPM of the one motor as required to permit the vehicle to negotiate the curve. |
