VEHICLE CONTROL APPARATUS, VEHICLE, AND VEHICLE CONTROL METHOD
First Claim
1. A vehicle control apparatus that is mounted in a vehicle having an engine, and a battery that is charged by an electric power generator that is driven by a motive power of the engine, the vehicle control apparatus comprising:
- an electronic control unit configured to(a) stop the engine;
(b) detect an amount of change in a state of charge of the battery;
(c) permit and prohibit stop of the engine by an idling stop control unit in accordance with the amount of change in the state of charge; and
(d) determine timings for the permission and the prohibition such that an amount of increase in the state of charge at a time when the engine is not stopped by the idling stop control becomes larger than an amount of decrease in the state of charge at a time when the engine is stopped.

Abstract
A request to fully charge a battery and a request to execute idling stop are made compatible with each other. A vehicle control apparatus is mounted in a vehicle having an engine, and a battery that can be charged by an electric power generator that is driven by a motive power of the engine. The vehicle control apparatus is equipped with an idling stop control unit that stops the engine, an SOC change amount detection unit that detects an amount of change in a state of charge (an SOC) of the battery, and an execution restriction unit that permits and prohibits stop of the engine by the idling stop control unit in accordance with the amount of change in the SOC. The execution restriction unit determines timings for the permission and the prohibition such that an amount of increase in the SOC at a time when the engine is not stopped by the idling stop control unit becomes larger than an amount of decrease in the SOC at a time when the engine is stopped.

10. A vehicle control method for controlling a vehicle having an engine, a battery that is charged by an electric power generator that is driven by a motive power of the engine, and an electronic control unit, the vehicle control method comprising:
-
stopping the engine by the electronic control unit; detecting, by the electronic control unit, an amount of change in a state of charge of the battery; permitting and prohibiting, by the electronic control unit, stop of the engine by an idling stop control in accordance with the amount of change in the state of charge, and determining, by the electronic control unit, timings for the permission and the prohibition such that an amount of increase in the state of charge at a time when the engine is not stopped by the idling stop control becomes larger than an amount of decrease in the state of charge at a time when the engine is stopped.
