Abstract: A vehicle has an engine as a driving source. The vehicle has a charge system which generates electric power by using a part of rotational output of an engine, and charges a battery by the generated electric power. Optimal shaft efficiency points are combinations of revolution speed and torque of the engine for maximizing the shaft efficiency. Optimal shaft efficiency line passes through the optimal shaft efficiency points for each engine output level. Warming-up operation line is defined by shifting the optimal shaft output efficiency line to a side to increase heat loss. An engine controller stores the lines. The engine controller performs a warming-up operation by operating the engine at a revolution speed and a torque on the warming-up operation line. The engine controller controls the battery to reduce possibilities of a full charge at a next warming-up.

Abstract: A control device for a hybrid vehicle includes setting unit and supplied heat amount control unit. The setting unit sets the amount of heat for heating supplied by an electric heating system and a heater core such that a battery SOC and coolant temperature are arranged at a predetermined operating point after a predetermined time. The control unit controls this amount of heat based on the setting by the setting unit. The predetermined point is an operating point, which is the closest to a line passing through a predetermined value in a battery SOC target range and a predetermined value in a coolant temperature target range and having a preset change rate, and which is settable within the predetermined time. The change rate is the same as a gradient of an approximate line in case of selection of any one engine operating point on an optimum fuel economy line.

Abstract: A control device for a hybrid vehicle includes an engine operating point setting device, a coolant temperature prediction device, a battery state-of-charge prediction device, and a determination device. The determination device determines whether an amount of heat of coolant is short or excess based on coolant temperature predicted by the coolant temperature prediction device and determines whether an amount of charge of a battery is short or excess based on SOC of the battery predicted by the battery state-of-charge prediction device. 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 device, the engine operating point setting device sets an engine operating point, which is shifted in a direction to eliminate the shortage or the excess.
