VEHICLE CONTROL DEVICE

摘要

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.

主权项

1. A vehicle control device controlling a hybrid vehicle including an engine, a motor generator, a power storage device which receives an electric power from or transmits the electric power to the motor generator and can be charged and discharged, and a heating device which includes an exhaust heater using an exhaust heat of the engine and a heat pump system using the electric power of the power storage device, the vehicle control device comprising:
a coolant-temperature acquiring portion acquiring a temperature of a coolant of the engine; a power-residual acquiring portion acquiring the power residual of the power storage device; and a heating start-timing determining portion determining a start timing of the heating device based on the temperature of the coolant and the power residual.
