A control device (180) includes a target rotation speed determination unit (202) that determines a target rotation speed of an engine, a filtering process unit (204) that receives an output of the target rotation speed determination unit (202), changes the received output such that the target rotation speed changes gently, and outputs the changed output, a property switching control unit (206) that switches properties of the filtering process unit (204) in accordance with a vehicle state, and a first torque value calculation unit (208) that calculates a target torque Tg* of a motor generator MG1 in accordance with a difference Ne between the output of the filtering process unit (204) and an actual rotation speed of the engine. Preferably, the property switching control unit (206) increases a time constant of the filtering process in accordance with a shift switch instruction (Spos) to switch a vehicle state from a traveling state to a neutral state.
