Abstract

본 발명은 차량의 주행 안전장치에 관한 것으로써, 오르막길 주행시 갑작스런 노면경사각 변화를 운전자에게 알려주고 자동변속기의 기어단을 쉬프트 다운시켜 안전운행을 도모하기 위한 것이다. 본 발명은 오르막길 판정을 위한 경사각 센서와, 차속을 산출하기 위한 차속센서와, 차량전방의 노면상태를 탐지하기 위한 초음파 송수신센서의 출력을 자동변속기 제어장치의 입력단에 연결하고, 계산된 노면경사각이 일정각도 이상이고, 차속이 일정속도를 초과한 상태에서 초음파 반사거리가 소정거리 이상인 것을 검출하였을 때 제어장치의 출력단에 연결된 부저를 작동하고 변속기 유압제어장치에 쉬프트 다운 제어신호를 보내 엔진 브레이크가 작동되게 한 것을 특징으로 한다.The present invention relates to a driving safety device for a vehicle. The present invention is to notify a driver of a sudden change of a road inclination angle when driving uphill and to shift down the gear stage of an automatic transmission for safe driving. The present invention connects the inclination angle sensor for determining the uphill, the vehicle speed sensor for calculating the vehicle speed, and the output of the ultrasonic transmission / reception sensor for detecting the road surface condition in front of the vehicle to the input of the automatic transmission control device, When it detects that the ultrasonic reflection distance is more than the predetermined distance while the vehicle speed exceeds the certain speed and operates the buzzer connected to the output of the control device, the engine brake is activated by sending a shift-down control signal to the transmission hydraulic control device. It is characterized in that.
