ABSTRACT:
A control method for an electrical appliance in a hybrid vehicle. When the electric appliance is connected, the output of the engine is maintained by reducing the output of the generator by the equivalent of the power consumed by the electric appliance while maintaining the revolution speed of the engine. The revolution speed of the engine is then gradually increased by adjusting the field current of the generator while monitoring the output of the generator. When the output of the engine is increased by the power consumed by the electric appliance, the engine is operated at a constant revolution speed and a constant output at the operation point on the output line of the engine with WOT. Thus, the engine is prevented from stopping due to a rapid increase in the load. Owing to a gentle change in the output, the emission is favorable. Since the output of the engine does not deviate from the output line of the engine with WOT (wide open throttle), the fuel consumption is also good.
