Title:
CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2007315226
Kind Code:
A
Abstract:

To properly start an internal combustion engine while preventing the deterioration of a storage device for supplying an electric power to a motor for starting the internal combustion engine.

The start control part 23 of a torque calculation part 22 calculates the deviation of a target rotational speed and an actual rotational speed to an engine rotational speed, controllably amplifies the deviation by PI (proportional integral) operation according to the start mode of the internal combustion engine E determined by a start mode determination part 21, and calculates a torque command value. When the internal combustion engine E is in a pulse start mode, the start control part 23 acquires a control gain for setting the state of a feedback processing system to the stability limit state according to various temperatures such as a battery temperature, engine water temperature, and a T/M oil temperature, the remaining capacity of a battery 3, or the DC voltage of the battery 3 by a map retrieval for a pre-set predetermined map, and calculates a torque command value.
