Abstract

A motor vehicle includes an electromechanical transmission system having an engine driven generator and a motor adapted to drive one or more wheels of the vehicle, the generator being connected to the motor via a DC to DC converter by which the current output of the generator may be varied to provide appropriate current input to the motor and a control unit including a transducer to sense the performance of the vehicle and a speed control device for operation by the driver, said control unit being arranged to control the engine and the DC to DC converter to optimize operation of the transmission to match the requirements of the driver to the performance of the vehicle.
