ABSTRACT:
Controller 40 receives accelerator opening and brake depressing amounts, and the output of an ammeter 30 and voltmeter 32 as inputs. In response to the state of these input signals, the controller 40 determines the timing to detect the state of charge (SOC) of the battery 10 and detects the SOC of the battery 10. That is, it is first judged that the SOC is not more than a predetermined value if the voltage of the battery 10 is not more than a predetermined value when the accelerator opening is not more than a predetermined value. It is next judged that the SOC is not more than a predetermined value if the voltage of the battery 10 is not more than a predetermined value when the brake is depressed beyond a certain degree. In these cases, the engine 24 is driven to cause a generator 22 to perform generation of electricity to charge the battery 10.
