Abstract

A vehicle is equipped with an engine, a motor generator, an electricity storing part, and an air-conditioning part. A control device for the vehicle includes: a determining portion that determines whether the vehicle approaches a destination; an estimating portion that estimates a cooling demand or a heating demand for a next trip of the vehicle; and a changing portion that changes a target value of a charge state of the electricity storing part from a normal value to a different value when the determining portion determines that the vehicle approaches the destination and when the estimating portion estimates that there is the cooling demand or the heating demand.

First claim

What is claimed is:

1. A control device for a vehicle equipped with an internal combustion engine, a motor generator that generates power by being driven by the internal combustion engine, an electricity storing part that outputs or inputs electric power with the motor generator to discharge or charge, and an air-conditioning part that conducts at least one of a heating operation and a cooling operation, wherein the control device comprising:
a determining portion that determines whether the vehicle approaches a destination;
an estimating portion that estimates a cooling demand for the cooling operation or a heating demand for the heating operation in a next trip of the vehicle; and
a changing portion that changes a target value of a charge state of the electricity storing part from a normal value to a different value when the determining portion determines that the vehicle approaches the destination and when the estimating portion estimates that there is the cooling demand or the heating demand.

2. The control device according to claim 1 , wherein
the changing portion changes the target value from the normal value to the different value that is smaller than the normal value when the estimating portion estimates that there is the heating demand.

3. The control device according to claim 1 , wherein
the changing portion changes the target value from the normal value to the different value that is larger than the normal value when the estimating portion estimates that there is the cooling demand.

4. The control device according to claim 1 , wherein
the estimating portion estimates the heating demand or the cooling demand based on an operation history of the air-conditioning part.

5. The control device according to claim 1 , wherein
the estimating portion estimates the heating demand or the cooling demand based on a temperature of air outside of the vehicle.

6. The control device according to claim 1 , further comprising:
an acquisition portion that acquires information of the destination from a navigation device, wherein
the determining portion determines whether the vehicle approaches the destination based on the information of the destination.

7. The control device according to claim 1 , wherein
the determining portion determines that the vehicle approaches the destination when an elapsed time period elapsed from a trip start of the vehicle is longer than or equal to a predetermined time period.

8. The control device according to claim 1 , wherein
the determining portion determines whether the vehicle approaches the destination based on a past drive history of the vehicle.
