Title:
エンジンのアイドル回転数制御装置
Document Type and Number:
Japanese Patent JP3601254
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent a target generating torque drop when speed is reduced by external disturbance at the time of idle, while preventing generation of a step difference feeling continuing engine torque demand control at the time of idle. SOLUTION: A device is provided with means 101 for calculating a first target torque on the basis of a demand of a driver, means 102 for calculating an engine load such as friction, means 103 for calculating a second target torque in this load, means 104 for calculating a target generating torque from first and second target torque, means 105 for controlling a fuel injection rate and the like so as to realize a target generating torque, and an idle speed control means 106, and torque demand control noticed to a torque is carried out. A target idle speed is applied instead of real engine rotating speed by a switching means 107 as an engine speed parameter at the time of idle, and thereby, it is possible to prevent reduction of speed caused by external disturbance.
