VEHICLE CONTROL SYSTEM
First Claim
1. A vehicle control system comprising:
- an engine mounting to a vehicle and burning a fuel to generate driving power;
a battery enabling to charge and discharge;
a motor generator being supplied with electric power from the battery to generate driving power, and being supplied with the driving power from the engine to generate electric power and charge the battery;
a power conversion device converting the electric power supplied from the battery and supplying to the motor generator to generate the driving power in the motor generator, and converting the electric power generated by the motor generator and supplying to the battery to charge the battery; and
a control device controlling the engine and the power conversion device,whereinwhen the remaining capacity of the battery is equal to or less than a low limit threshold, the control device controls the engine and the power conversion device so as to make remaining capacity of the battery reach a target value, andwhen the temperature of the battery is less than the threshold value, the control device reduces the target value of the remaining capacity of the battery compared with a case where temperature of the battery is equal to or more than a threshold value.

Abstract
The vehicle control system includes an engine, a battery, a motor generator that generates driving power and generates electric power to charge the battery, a power conversion device that generates driving power to the motor generator and charges the battery, and a control device that controls the engine and the power conversion device. The control device controls the engine and the power conversion device and the remaining capacity of the battery is equal to a target value when the remaining capacity of the battery is equal to or less than the lower threshold. The control device reduces the target value of the remaining value of the battery as compared with a case where temperature of the battery is equal to or more than a threshold value when the temperature of the battery is less than the threshold value.
