Control device for vehicle

摘要

A vehicle is provided with an air conditioning device that heats a passenger compartment, using cooling water passing through an internal combustion engine as a heat source, and a seat heater, which heats a seat in the passenger compartment by using an electric power from a battery as a heat source. An electronic control device performs EV travel of the vehicle by driving a motor generator while setting the internal combustion engine to a stop state and restarts the internal combustion engine when a cooling water temperature becomes equal to or less than a predetermined temperature during the EV travel. When a heating request is output to make the air conditioning device heat the passenger compartment during vehicle travel, the electronic control device reduces the heating degree of the air conditioning device and increases the heating degree by the seat heater during EV travel in comparison with non-EV travel.

主权项

1. A vehicle comprising:
an internal combustion engine for driving the vehicle; a motor for driving the vehicle; a main heating device for heating a passenger compartment by using cooling water passing through the internal combustion engine as a heat source; an auxiliary heating device for heating the passenger compartment by using a power supply from a battery as a heat source; a driving control portion for performing electric vehicle (EV) travel of the vehicle by driving the motor while setting the internal combustion engine to a stop state and restarting the internal combustion engine as a temperature of the cooling water becomes equal to or less than a predetermined temperature during EV travel; and a heating control portion for controlling the main heating device and the auxiliary heating device in correspondence with a heating request, wherein, when the heating request is output to make the main heating device heat the passenger compartment during travel of the vehicle, the heating control portion reduces a heating degree by the main heating device during EV travel in comparison with non-EV travel and causes the auxiliary heating device to heat the passenger compartment.
