A torque reducing process reduces torque of a multiphase rotating electric machine when a magnitude of current in a particular phase of the rotating electric machine remains greater than or equal to a given value. A deactivating process deactivates combustion control in a deactivated cylinder and continues combustion control in the remaining cylinders. A fluctuation torque applying process cyclically fluctuates the torque of the rotating electric machine in a cycle that is an integral multiple of a compression top dead center occurrence cycle when the deactivating process is being executed. A prohibiting process prohibits execution of the deactivating process in a predetermined situation where a rotation speed of a rotary shaft of the rotating electric machine is less than or equal to a given speed.

An intake and exhaust system includes an engine, an intake air channel, an exhaust gas channel, an EGR channel, an EGR valve, and a control device. By adjusting an opening degree of the EGR valve, the control device executes EGR control processing to control a flowrate of a recirculating exhaust gas. An isolation valve is disposed in the EGR channel closer to the exhaust gas channel than the EGR valve is. An air admittance valve is disposed in the EGR channel closer to the exhaust gas channel than the EGR valve is and closer to the intake air channel than the isolation valve is. The control device executes learning processing to learn a relationship between an actual flowrate and a reference flowrate while the isolation valve is closed and the air admittance valve is opened. The control device executes the EGR control processing based on a learning processing result.
