Drive apparatus for a hybrid fuel electric vehicle

摘要

A drive device for a fuel-driven and electrically driven vehicle has an IC engine (10), a generator (11) that can be driven by the engine, a rectifier (12) to which the output voltage of the generator can be given, a DC rail (13) which can be fed with an intermediate circuit voltage by the rectifier, inverters (14-20) which are connected to the DC rail, client motors (2-8) which can be driven in speed- and/or torque-controlled fashion and each fed by an inverter plus an open/closed-loop control device (23) by means of which the vehicle functions can be controlled. The open/closed-loop control device has a speed control unit (24) with a speed measurement transmitter (30) by which the speed of the engine can be controlled according to load demand and an output voltage control unit (25) by means of which the excitation of the generator can be controlled so that the intermediate circuit voltage on the DC rail can be held in a given permitted range.
