Title:
エンジン制御装置
Document Type and Number:
Japanese Patent JP4409800
Kind Code:
B2
Abstract:
Evacuation operation performance is improved when any abnormality occurs in an electronic throttle control system.When any serious abnormality occurs, a first abnormality storage element (133) operates, a load relay for a power supply circuit (104a) of a throttle valve open/close controlling motor (103) is de-energized to operate a first alarm and display (109a). Thus a first device carries out the evacuation operation by a fuel cut control.When any slight abnormality occurs, a second abnormality storing element (136) comes to actuate thereby a second alarm and display (109b) being operated. Thus a second device carries out the evacuation operation using together a throttle valve opening control by the motor 103 and the fuel cut control.
