A motor vehicle includes an electromechanical transmission system having an engine (11) driven generator (10) and a motor (12) adapted to drive one or more wheels (14) of the vehicle, the generator (10) being connected to the motor (12) via a DC to DC converter (31) by which the current output of the generator (10) may be varied to provide appropriate current input to the motor (12) and a control unit (34) including a transducer (33) to sense the performance of the vehicle and a speed control device (35) for operation by the driver, said control unit (34) being arranged to control the engine (11) and the DC to DC converter (31) to optimise operation of the transmission to match the requirements of the driver to the performance of the vehicle. <IMAGE> |
