Abstract:
1. A vehicle control device mounted on a vehicle having: an engine; a battery that is chargeable with an amount of electric power generated by a generator which is driven with power of the engine; and auxiliary machinery that are operated with electric power of the battery, the vehicle control device comprising: an idle reduction controller that performs idle reduction control; an SOC detector that detects a state of charge (SOC) of the battery; a current value obtaining section that obtains a current value of electric current flowing through the auxiliary machinery; a current correcting section that corrects the current value; an idle reduction capacity setting section that sets a capacity for idle reduction, based on the current value corrected by the current correcting section, wherein the capacity for idle reduction is expected to be used in a stop and start period from an engine stop to an engine restart by the idle reduction control, in an available SOC range of the battery, during running of the vehicle; and a remaining capacity controller that controls the amount of electric power generated by the generator, in order to avoid a remaining capacity, which corresponds to the SOC detected by the SOC detector, in the available SOC range from becoming less than the capacity for idle reduction during running of the vehicle, wherein the current correcting section comprises:
