Abstract
An internal combustion engine is provided that executes fuel injection and ignition with respect to a cylinder that remains stopped in an expansion stroke, and that performs ignition startup that starts up the internal combustion engine by rotationally driving a crankshaft by pressure of combustion accompanying the fuel injection. A motor generator (MG) that can rotationally drive the crankshaft is provided. A required assist torque Ast_trq exerted by the MG at the time of ignition startup is determined based on a maximum value Cyl_prss of an in-cylinder pressure that is detected by an in-cylinder pressure sensor at the time of ignition startup. The MG is controlled at the time of ignition startup based on the required assist torque Ast_trq that is determined.
