Filed: 2001-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a start control apparatus for an internal combustion engine that can maximally downsize a motor while properly performing forcible revolution of the internal combustion engine to start the engine. SOLUTION: The motor 9 is driven in a state where a clutch 6 is released, that is, the motor is driven to be separated from the engine 2, at a time of starting the engine. At this time, torque of the motor 9 is stored as inertial force in a rotational direction. Then, the clutch 6 is engaged to start cranking of the engine 2, after the motor 9 is in the rotating state where the motor can perform cranking appropriate for starting the engine. The cranking using two forces of the torque and inertial force for the motor 9 is appropriately performed for starting the engine. The output torque of the motor 9 required at this time is low, since the cranking is performed by using not only the torque of the motor 9 but also the inertial force.
