Method for preventing an engine stall and idle RPM drop when a car stops

摘要

The present invention is to prevent engine stall when the vehicle is stopped and to prevent the idle RPM (RPM) from falling during the stop of the vehicle, and the engine stall when the vehicle stops the air volume correction can respond quickly during deceleration that the load is constantly changing and The present invention relates to a method of preventing idle rotation reduction. The method includes determining whether the vehicle speed is vehicle speed 0 or 0 vehicle speed when the vehicle is idle; In the above step, the target idle rotation speed when the vehicle is stopped and the target idle rotation speed N1 when the vehicle speed 0 or 0 vehicle speed coincide, and the actual rotation speed N and the vehicle speed 0 or 0 vehicle speed Comparing whether or not the target idle rotational speed (N1) when When the actual rotation speed N and the target idle rotation speed N1 at the vehicle speed 0 or 0 vehicle speed are the same, the target idle rotation speed when the actual rotation speed N and the vehicle speed 0 or 0 vehicle speed ( It is determined whether the time T until N1) is equal to the set time, and the target idle rotation speed N0 when the vehicle is stopped is matched with the target idle rotation speed.
