Abstract
본 발명은 자동변속기를 사용하는 자동차에서 변속단의 제어방법에 관한 것으로, 운행되는 자동차의 브레이크 페달 구동이 검출되면 저단의 변속비로 자동으로 쉬프트(Shift)되도록 하여 엔진 브레이크의 효과를 향상시키도록 한 것이다.The present invention relates to a control method of a shift stage in a vehicle using an automatic transmission. When a brake pedal drive of a driving vehicle is detected, the shift speed is automatically shifted to a low gear ratio to improve the effect of the engine brake. will be.
본 발명은 자동변속기를 장착한 자동차의 운행 상태에서 브레이크 페달의 구동 신호를 검출하면 감속되는 주행속도의 비에 따라 현재 운행 모드로 선택된 기어의 변속단보다 저단의 기어의 자동으로 쉬프트시켜 고속주행 모드에서의 급감속시 엔진 브레이크 효과를 통해 제동거리를 단축시켜 운행에 신뢰성을 제공한다.According to the present invention, when a driving signal of a brake pedal is detected in a driving state of an automobile equipped with an automatic transmission, a gear of a lower gear than the gear of the gear selected as the current driving mode is automatically shifted according to the ratio of the driving speed which is decelerated. The engine braking effect reduces the braking distance during sudden deceleration of the engine and provides reliability to the operation.
