Hybridfahrzeug-Regelung mit Nutzung der überschüssigen Verbrennungsmotorleistung für den Generatorantrieb zum Laden der Batterie

摘要

A drive control apparatus for an automotive vehicle having an electric motor (14) operated by an electric energy generated by an electric generator (14) and stored in an energy storage device (22), and an engine (12) operated by combustion of a fuel, the apparatus having an electricity generating drive mode in which the vehicle is driven by the engine while the electric generator is operated by the engine to charge the electric energy storage device, wherein a changing control device (40) is operable in the electricity generating drive mode, for controlling the engine to operate in a substantially steady state so as to provide a steady state output, and controlling electric power to be generated by the electric generator such that the electric power corresponds to surplus power of the engine which is equal to a difference between the steady state output of the engine and required vehicle drive power which is currently required to drive the vehicle and which is smaller than the steady state output.
