PROBLEM TO BE SOLVED: To provide a control device at starting capable of avoiding blowing up of an engine rotation speed at starting of the engine regardless of fuel property or the like and starting the internal combustion engine in a short time. SOLUTION: The control device at starting changes a solenoid clutch 51b to the connection state when angular acceleration of a crank shaft becomes larger than a first threshold value, namely when excessive rising (blowing up) of the engine rotation speed is expected after the engine 10 starts combustion. Thereby, torque (necessary drive torque) required for driving an alternator 51 (equipment) by the engine 10 is increased from the first torque value to the second torque value. Accordingly, excessive rising of the engine rotation speed can be suppressed. Whereas, when a rising ratio of the engine rotation speed is small, the angular acceleration of the crank shaft does not become larger than the first threshold value. Accordingly, since the solenoid clutch 51b is maintained in the disconnection state, the engine rotation speed is gently raised in a short time. COPYRIGHT: (C)2008,JPO&INPIT
