Title:
内燃機関制御装置
Document Type and Number:
Japanese Patent JP4237214
Kind Code:
B2
Abstract:
In throttle control, a throttle opening is set with sufficient control accuracy in accordance with the operating state of an engine despite variations in a throttle body and various kinds of sensors. A target effective opening area is calculated from a target amount of intake air, an atmospheric pressure, an intake pipe internal pressure and an intake air temperature by using a flow rate formula for a throttle type flow meter. A target throttle opening is calculated from a correlation map. An actual effective opening area is calculated from the amount of intake air, the atmospheric pressure, the intake pipe internal pressure, and the intake air temperature by using the above-mentioned flow rate formula, and a learning throttle opening is calculated from the correlation map. The target throttle opening is corrected by a throttle opening learning value calculated from a deviation between the target throttle opening and the learning throttle opening.
