Patent ID: 8660733

Claim:
A control device for a hybrid vehicle including: an engine that is configured to output driving force for driving the vehicle and driving force for generating electricity; a battery that is charged with electricity and discharges electricity; a motor generator that is capable of outputting driving force for driving the vehicle by the electricity discharged from the battery and is capable of generating electricity by the driving force outputted from the engine to supply the battery with electricity; a heat load that is configured to consume heat of coolant of the engine; and an electricity load that is configured to consume the electricity of the battery, the control device disposed in the hybrid vehicle and comprising: an engine operating point setting means for setting an engine operating point when the engine is operated; a coolant temperature prediction means for predicting coolant temperature after a predetermined period of time based on a state in which the heat load consumes the heat; a battery state-of-charge prediction means for predicting a state of charge of the battery after the predetermined period of time based on a state in which the electricity load consumes the electricity; and a determination means for determining whether an amount of heat of coolant is short or excess based on the coolant temperature predicted by the coolant temperature prediction means and for determining whether an amount of charge of the battery is short or excess based on the state of charge of the battery predicted by the battery state-of-charge prediction means, wherein when at least one of the amount of heat and the amount of charge is short or excess as a result of the determination by the determination means, the engine operating point setting means sets the engine operating point, which is shifted in a direction to eliminate the shortage or the excess of the at least one of the amount of heat and the amount of charge.
