Abstract

본 발명은 차량용 차속 자동제어장치 및 방법에 관한 것으로, 일반적으로 차량에 의한 주행도중 일어날 수 있는 과속주행을 막기 위하여 과속운전시 자동으로 차속을 감속시키고자 하는 경우에 종래에는 차량 감속시 운전자의 수동조작에만 의존했음으로 인해 운전자가 졸음운전으로 미처 현재속도를 지각하지 못함으로써 발생되는 돌발사고는 미연에 방지하지 못하는 문제점을 해소하기 위하여, 차량용 엔진의 인젝터(1)측에 인젝터 전원차단 릴레이(5)를 구비하여 차량이 주행중 제한속도 이상으로 과속을 하게 되면 자동으로 차량 엔진측 인젝터(1)의 연료 분사가 중지되도록 상기 인젝터 전원(4)을 차단시키므로써 운전자가 수동조작으로 미처 차량의 속도를 감속시키지 못했을 경우에 발생될 수 있는 사고를 미연에 방지할 수 있게 되는 효과가 있다.[0001] The present invention relates generally to an automatic vehicle speed control system and method for a vehicle, and more particularly, to a vehicle speed control system for automatically controlling a vehicle speed during an overspeed operation in order to prevent overspeed driving, The injector power-off relay 5 (5) is provided on the injector 1 side of the vehicle engine in order to solve the problem that the driver can not prevent the accident caused by the inability to perceive the current speed due to the sleeping operation due to the fact that he / The injector power supply 4 is automatically shut off so that the fuel injection of the injector 1 on the vehicle engine side is stopped so that the driver can manually adjust the speed of the not- It is possible to prevent an accident that may occur when the vehicle is not decelerated .
