Abstract
When an exhaust gas switching valve is in a closed state, a target rotation speed Ne* and a target torque Te* are set in the same way as when the exhaust gas switching valve is in an open state to control an engine (S, S). A motor torque command Tmis set by using the target torque Te* corrected by a correction torque ΔT based on an engine rotation speed Ne, and also a motor torque command Tmis set so that a torque demand Tr* is delivered to a drive shaft to control motors MGand MG(Sto S). Thereby, since the exhaust gas switching valve is in a closed state, even if the output from the engine decreases, the engine and the motors MGand MGcan be controlled properly.
