Document Type and Number:
Japanese Patent JP5489270
Kind Code:
B2
Abstract:
A system for controlling voltage to be supplied to electronic devices in a hybrid vehicle that includes: a main battery for storing power to be supplied to a motor of the vehicle; a sub-battery for storing power to be supplied to electronic devices of the vehicle; a low-voltage DC/DC converter (LDC) for converting a high voltage of the main battery into a low voltage and providing the low voltage to the sub-battery and the electronic devices; and a power controller for controlling power of the main battery, the LDC, and the sub-battery. The power controller controls the voltage to be supplied to the electronic devices with a low voltage, a reference voltage higher than the low voltage, and a high voltage higher than the reference voltage in accordance with an idle stop state, a constant velocity traveling state, an acceleration state, and a deceleration state of the vehicle.
