Abstract:
A vehicle includes an engine, a first MG, a second MG, a main battery which can be charged and discharged, and a heating device. The heating device includes an exhaust heater which uses an exhaust heat of the engine, and a heat pump system which uses an electric power of the main battery. A hybrid control device determines a start timing of the heating device, based on a coolant temperature and a SOC. Specifically, the start timing of the heating device is determined such that a timing that the coolant temperature reaches a target temperature matches a timing that the SOC reaches a target value. After a warming-up operation is completed, an EV travelling of the vehicle can be executed according to the electric power of the main battery charged in the warming-up operation, and a fuel consumption of the engine is improved.
