Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/033354
Kind Code:
A1
Abstract:
The vehicle control device comprises an engine, a starter (17), an auxiliary battery (21), and a high-voltage battery (19). The vehicle control device is equipped with a DC-DC converter (23) that is connected between the auxiliary battery and the high-voltage battery, a capacitor (26) that is connected to a high-voltage-battery-side circuit, a high-voltage battery assessment unit, and a startup control unit. The startup control unit executes power boost/startup control, whereby an output voltage of the auxiliary battery is boosted by the DC-DC converter, the capacitor is charged with necessary electric energy for starting the engine by using an output voltage of the DC-DC converter, and the starter is driven to start the engine by using the electric energy charged in the capacitor.
