Abstract

A vehicle control device that controls an air conditioning device and a battery in a vehicle that uses a coolant of the air conditioning device that cools a vehicle cabin for cooling the battery, the vehicle control device including: an air conditioning load determination unit that determines whether the air conditioning device is driven by a predetermined load or more; and a battery input-output control unit that controls at least one of an input power or an output power of the battery. When the air conditioning device is driven by the predetermined load or more, at least one of the input power or the output power is restricted without cooling the battery.

First claim

What is claimed is:

1. A vehicle control device that controls an air conditioning device and a battery in a vehicle that uses a coolant of the air conditioning device that cools a vehicle cabin for cooling the battery, the vehicle control device comprising:
an air conditioning load determination unit that determines whether the air conditioning device is driven by a predetermined load or more; and
a battery input-output control unit that controls at least one of an input power or an output power of the battery,
wherein when the air conditioning device is driven by the predetermined load or more, at least one of the input power or the output power is restricted without cooling the battery.

2. The vehicle control device according to claim 1 , further comprising:
an outside air temperature detection unit that detects an outside air temperature of the vehicle; and
an outside air temperature determination unit that determines whether the outside air temperature is lower than a predetermined temperature,
wherein when the outside air temperature is lower than the predetermined temperature, the input power and the output power are not restricted.

3. The vehicle control device according to claim 1 , further comprising:
a battery temperature detection unit that detects a temperature of the battery; and
a battery temperature determination unit that determines whether the temperature of the battery is lower than a predetermined temperature,
wherein when the temperature of the battery is lower than the predetermined temperature, the input power and the output power are not restricted.

4. The vehicle control device according to claim 1 , wherein when the air conditioning device is driven by the predetermined load or more, only a supply of power to the battery is restricted and an output of power from the battery is not restricted.
