Abstract
A hybrid vehicle controller controls a start or a stop of an engine according to a heating requirement or an engine-warming requirement. When at least one of the heating requirement and the engine-warming requirement is generated and a state of charge (SOC) of a main battery is higher than a specified threshold, the controller performs an SOC-fall-control to drop an SOC of a main battery. When the SOC of the main battery falls to a specified value, the engine is restarted. Since the engine can be started in a state where the SOC is lower enough than the upper limit by performing the SOC-fall-control, the engine output power can be converted into the heat for heating the passenger compartment or warming-up the engine.
