Title:
内燃機関の制御装置
Document Type and Number:
Japanese Patent JP5751344
Kind Code:
B2
Abstract:
The present invention addresses a solution of improving precision with which requested torque at a time of a transient operation is realized in a control device for an internal combustion engine that controls torque that is generated by an internal combustion engine by control of an air amount by means of a throttle. To this end, the present control device calculates a target intake pipe pressure for realizing a target air amount, and calculates predicted pump loss from the target intake pipe pressure. By adding the predicted pump loss to requested torque to the internal combustion engine, 360° indicated requested torque that should be realized in a compression/expansion strokes is calculated. An air amount for realizing the 360° indicated requested torque is calculated as the target air amount, and an opening of the throttle is determined based on the target air amount.
