A method to control an engine of a vehicle of the present invention comprises: a step of a controllers determining if a time, when there is no knocking of the engine, is longer than a first standard time based on knocking sensing information; a step of, when the time, when there is no knocking of the engine, is longer than the first standard time, the controllers controlling the ignition angle of the engine to advance for a second standard time and detecting if there occurs a knocking of the engine; a step of, when a signal, which indicates that no knocking is occurring in the engine, is detected, the controllers estimating the current humidity of external air, which corresponds to the angle advancement quantity of the ignition angle, based on a lookup table which includes humidity of external air of the vehicle in accordance with the angle advancement quantity of the ignition angle; and a step of the controllers controlling to advance the ignition angle of the engine for the angle advancement quantity of the ignition angle which corresponds to the estimated current humidity. The present invention aims to provide a method to control an engine of a vehicle and an engine controller of the vehicle, which can estimate the humidity of air outside the vehicle by using knock control of the engine and advance the ignition angle by using the estimated humidity.

    차량의 엔진 제어 방법은, 제어기가 노킹 센싱(knocking sensing) 정보를 근거로 하여 엔진의 노킹이 없는 시간이 제1 기준 시간보다 큰 지 여부를 판단하는 단계와, 엔진의 노킹이 없는 시간이 제1 기준 시간보다 클 때, 제어기가 엔진의 점화각을 제2 기준 시간만큼 진각(advance)하도록 제어하여 엔진의 노킹이 발생하는 지 여부를 검출하는 단계와, 엔진의 노킹이 발생하지 않음을 지시(indication)하는 신호가 검출될 때, 제어기가 점화각의 진각량에 따른 차량의 외부 공기의 습도를 포함하는 참조 테이블(lookup table)에 근거하여 점화각의 진각량에 대응하는 현재 외부 공기의 습도를 예측하는 단계와, 제어기가 엔진의 점화각을 상기 예측된 현재 습도에 대응하는 점화각의 진각량 만큼 진각(advance)하도록 제어하는 단계를 포함한다.
