ABSTRACT:
When an actual output power level of an engine is greater than a preset engine power demand due to the higher density of intake air in a cold environment, the control procedure of the invention controls a motor to raise a rotation speed of the engine with a throttle opening TH kept at a current level, so as to make the actual output power level of the engine substantially equal to the engine power demand (this is attained by, for example, a change of a target drive point from a point A to a point B). This arrangement effectively restrains a battery from being charged with an unexpectedly large electric power and prevents frequent changeover between the stop and the start of the engine with a significant variation in current state of charge (SOC) of the battery.
