Abstract: The invention relates to a control device of a multi-cylinder internal combustion engine. The control device starts executing an ignition engine start control to restart the engine operation when a predetermined engine restart request is generated, a last signal output from a crank angel sensor corresponds to the compression TDC and a signal is output from the sensor before a time elapsing from the output of the last signal reaches a predetermined time. The control device starts executing a starter engine start control when the engine restart request is generated, the last signal output from the sensor corresponds to the compression TDC and no signal is output from the sensor before a time elapsing from the output of the last signal reaches the predetermined time. The control device sets the predetermined time on the basis of a last engine speed acquired on the basis of the last signal and a signal output from the sensor immediately before the last signal is output such that the predetermined time set when the last engine speed corresponds to a first engine speed, is longer than the predetermined time set when the last engine speed corresponds to a second engine speed larger than the first engine speed.

Abstract: When a K0 clutch 34 is interrupted to stop a direct injection engine 12 during vehicle running, if a stop position of a crankshaft 114 is out of a range of a target stop range φtarget, the once interrupted K0 clutch 34 is temporarily frictionally engaged to slightly rotate the crankshaft 114. As a result, the crankshaft 114 stopped near compression TDC (top dead center) is rotated to and stopped in a minimum region of pumping energy in combination with a pumping action. Since the minimum region of the pumping energy overlaps with the target stop range φtarget suitable for ignition start associated with a small assist torque at the time of engine start, the ignition start can properly be performed at the next engine start and the assist torque at the time of engine start can be reduced.

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.
