Abstract
A hybrid vehicle of the invention has an engine, a planetary gear unit including a carrier linked with rankshaft of the engine and a ring gear linked with a drive shaft, a motor MGinputting and outputting power to and from a sun gear of the planetary gear unit, and a motor MGinputting and outputting power to and from the drive shaft. During a drive of the hybrid vehicle in a light load state and under a drive restriction of the motor MG, the hybrid vehicle corrects a target revolution speed Ne* of the engine to make a calculated average charge-discharge electric power Wbave of a battery equal to a charge-discharge electric power demand Wb*, while keeping a torque of the engine unchanged (steps Sto S), and controls actuation of the engine and the motors MGand MG
