Safety device of idle contact type abolition type throttle sensor

摘要

The present invention relates to an apparatus for setting an idle on area through a throttle full closing point by a linear sensor output when the throttle is completely closed at the time of malfunction of the linear sensor The present invention relates to a safety device for an idle-contact-disconnection-type throttle sensor, which can prevent a starting-off or an idling-unstable phenomenon from occurring. There is a problem that the engine rotation speed becomes unstable when the load is increased such as turning on the air conditioner or turning on the lamp at the time when the throttle is completely closed and the engine rotation speed becomes unstable, From the learning value of the full closing degree by the linear sensor, the opening region of the throttle is shifted to the idle ON region And when an abnormality occurs in the output of the linear sensor, the idle speed controller is controlled by opening the throttle with a predetermined opening amount corresponding to the number of revolutions of the engine. According to the present invention, When the throttle is fully closed in a state in which idling on can not be performed, it is possible to prevent a start-up failure or an unstable phenomenon due to unstable engine rotation speed, thereby improving the safety of the vehicle.
