摘要

In response to the driver's release of an accelerator, the procedure of the invention sequentially compares an observed charge-discharge electric power Wb of a battery with two reference values Wr 1 and Wr 2 , which are set on the basis of an input restriction Win of the battery. The procedure changes over a control mode among an ordinary state varying control (processing of and after step S 160 ) to gradually lower a revolution speed Ne of an engine with torque output, an idling state varying control (step S 220 ) to gradually lower the revolution speed Ne of the engine while idling the engine, and a fuel supply shutoff state varying control (step S 230 ) to shut off fuel supply to the engine.
