Abstract

본 발명은 자동차의 속도 자동저감장치 및 그 방법에 관한 것이다.The present invention relates to an automatic speed reduction device for a vehicle and a method thereof.

본 발명은 자동차의 소정위치에 장착되어 급제동시에 주행속도를 단계적으로 저감하고자 하는 운전자의 조작 신호를 입력받는 조작스위치와, 상기 조작스위치의 출력단에 접속되어 자동차의 비상등에 구동신호를 출력하며, 주행중인 자동차의 속도에 따라 자동차의 엔진에 제동신호를 단계적으로 출력하는 마이컴과, 상기 마이컴의 출력단에 접속되어 자동차의 엔진에 제동신호를 인가하는 속도제어부와, 상기 엔진의 출력속도를 감지하여 이를 상기 마이컴에 입력하는 속도감지센서로 이루어짐을 특징으로 하여 자동차가 주행중 위급사태에 직면하여 급제동 수행시에 운전자가 스위치를 조작하면 자동으로 엔진브레이크를 동작시켜 자동차의 주행속도를 단계적으로 저감시킴으로써 자동차의 주행안전성을 증대하는 것이다.The present invention is mounted on a predetermined position of the vehicle, the operation switch receives a driver's operation signal to gradually reduce the running speed during braking, and is connected to the output terminal of the operation switch outputs the drive signal to the emergency light of the vehicle, while driving A microcomputer for outputting a braking signal to the engine of the vehicle in accordance with the speed of the vehicle; and a speed controller connected to the output terminal of the microcomputer to apply a braking signal to the engine of the vehicle; It consists of a speed sensor that inputs to the microcomputer.If the driver operates the switch during sudden braking in the face of an emergency during driving, the engine brake is automatically operated to reduce the running speed of the vehicle step by step. It is to increase safety.
