Abstract

본 발명은 ECU에 리셋(RESET) 신호가 인가되어, ECU가 초기화되면 상기 리셋 신호 발생 시 엔진의 상태와, 현재 상태의 엔진 회전수를 파악하여, 엔진이 정상 상태에서 상기 리셋 신호가 인가되었고 현재의 엔진 회전수가 일정 수준 이상인 경우에는 엔진을 상기 초기화 상태에서 정상 상태로 강제 천이시키도록 하는 ECU 제어 방법을 제공함으로써, 자동차의 주행이 보다 안정성 있게 이루어질 수 있도록 하는 효과가 있다.According to the present invention, when a reset signal is applied to an ECU, and the ECU is initialized, the engine recognizes the state of the engine and the engine speed of the current state when the reset signal is generated. When the engine speed is greater than a predetermined level, by providing an ECU control method for forcibly shifting the engine from the initial state to the normal state, there is an effect that the driving of the vehicle can be made more stable.

ECU에 리셋(RESET) 신호가 인가되어 ECU가 초기화되면, 상기 리셋 신호 발생 시 엔진의 상태와 현재 상태의 엔진 회전수를 파악하여, 엔진이 정상 상태에서 상기 리셋 신호가 인가되었고 현재의 엔진 회전수가 일정 수준 이상인 경우에는 엔진을 상기 초기화 상태에서 정상 상태로 강제 천이시키도록 함을 특징으로 하는 ECU 제어 방법.When the reset signal is applied to the ECU and the ECU is initialized, when the reset signal is generated, the engine state and the engine speed in the current state are recognized, so that the reset signal is applied in the normal state and the engine speed is present. If the predetermined level or more, the ECU control method characterized in that forcing the engine to transition to the normal state from the initialization state.
