Title:
VEHICLE CONTROL DEVICE, VEHICLE, AND VEHICLE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2013/072974
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve vehicle fuel consumption. Provided is a vehicle control device that is mounted in a vehicle having an engine, and a battery capable of being charged by the amount of power generated by an alternator driven by the motive force of the engine. The vehicle control device comprises: an idling stop control unit (90); a battery SOC calculation unit (120) that finds the SOC of the battery; a target SOC estimation unit (110) that sets an idling stop capacitance that is estimated to be used during a stop-and-start period from engine stop to restart by idling stop control, relative to a usable SOC range for the battery, during vehicle travel; and a residual capacitance control unit (130) that controls the amount of power generated by the alternator, so as to avoid the residual capacitance in the usable SOC range, corresponding to the SOC during vehicle travel, from falling lower than the idling stop capacitance.
