Hybridantriebssystem für ein Fahrzeug mit Mitteln zur Unterdrückung eines elektrischenGeneratorbetriebsmodus

摘要

Hybrid motor vehicle drive system (10) including an electric motor (14) operated by an electric energy generated by an electric generator (14) and stored in a storage (36), an engine (12), and a controller (28) for controlling the engine and electric generator to operate in an electricity generating drive mode when a predetermined condition is satisfied, such that the engine is operated so as to provide an output greater than a required power (PL) to drive the motor vehicle, so that the vehicle is driven by the engine with the required power while the electric generator is operated by the engine with a surplus power to charge the storage, and wherein the controller (28) includes a special control device (S4) operated in the event of a failure of the electric generator (14), for inhibiting the selection of the electricity generating drive mode and selecting an engine drive mode to operate the engine (12) for driving the motor vehicle with the required power, even when the predetermined condition is satisfied.
