車両用のエンジン制御装置
Document Type and Number:
Japanese Patent JP4121318
Kind Code:
B2
Abstract:
Escape running performance at the time of the occurrence of an abnormality in an electronic throttle control system is improved. At the time of the occurrence of a severe abnormality, an abnormality storage element is operated, and an electric supply load relay of a throttle valve driving motor is de-energized to return a throttle valve to the default, and further, an alarm display is actuated, and an upper limit engine rotational speed is suppressed by control of a fuel injection valve, and escape running is carried out. As a suppression rotational speed, a lower limit threshold at a stop, a rotational speed substantially in proportion to the output of an accelerator position sensor, a rotational speed substantially in inverse proportion to the output of a throttle position sensor, or a default threshold rotational speed is selected, and multiple escape running can be carried out.
