Abstract

본 발명은 차량의 요 레이트가 급격히 커질 경우 전륜각과 후륜각을 고려하여 후륜의 조타각을 제어하는 요 레이트를 이용한 4륜 조향시스템의 오류시 안전구동방법에 관한 것이다.The present invention relates to a safety driving method in case of an error of a four-wheel steering system using a yaw rate for controlling a steering angle of a rear wheel in consideration of a front wheel angle and a rear wheel angle when the yaw rate of a vehicle increases rapidly.

본 발명은 4륜 조향시스템이 장착되어 있는 차량에 있어 요 레이트를 감지할 수 있는 요 레이트센서와 전륜각과 후륜각을 감지하는 전륜각센서와 후륜각센서로부터 각각 차량의 상태에 대한 감지신호를 입력받아 요 레이트가 기준치 이상이라고 판단되는 순간 전륜각과 후륜각이 역위상이면 4륜 조향시스템의 구동을 차단하는 한편 동위상이라고 판단되면 현 상태를 그대로 유지하도록 하여 차량의 주행안정성을 확보할 수 있도록 하는 발명임.The present invention inputs a detection signal for the state of the vehicle from the yaw rate sensor for detecting the yaw rate, the front wheel angle sensor for detecting the front wheel angle and the rear wheel angle, and the rear wheel angle sensor for the vehicle equipped with the four-wheel steering system. If the front wheel and rear wheel angle are reversed at the moment when the yaw rate is judged to be higher than the reference value, the driving of the 4 wheel steering system is shut off. Invention.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 요레이트를 이용한 4륜 조향시스템의 오류시 안전구동방법을 설명하기 위한 구성도이다.1 is a block diagram illustrating a safety driving method in case of an error of a four-wheel steering system using a yaw rate according to the present invention.

Claims (2)

차량의 요 레이트내를 감지하는 요레이트센서(10)와 전륜각과 후륜각을 각각 감지하는 전륜각센서(12)와 후륜각센서(14)로 부터 차량의 요잉을 감지함과 더불어 전륜각과 후륜각을 감지하여 검출 요레이트가 설정값 이상일때 전륜각과 후륜각이 동위상이면 현상태를 유지시키고 역위상이면 4륜 조향시스템의 작동을 차단시켜 후륜을 중립의 위치로 조향시키도록 하는 요 레이트를 이용한 4륜 조향시스템의 오류시 안전구동방법.The front wheel angle and the rear wheel angle are sensed along with the yaw rate sensor 10 for detecting the yaw rate of the vehicle and the front wheel angle sensor 12 and the rear wheel angle sensor 14 for detecting the front wheel angle and the rear wheel angle, respectively. When the yaw rate is higher than the set value, the four wheels use the yaw rate to steer the rear wheel to the neutral position by blocking the operation of the four-wheel steering system if the front and rear wheel angles are in phase. Safe drive in case of steering system failure. 제 1 항에 있어서, 상기 검출 요레이트가 설정값 이상일때 요레이트가 줄어드는 방향으로 후륜을 조향하도록 하는 요 레이트를 이용한 4륜 조향시스템의 오류시 안전구동방법.The method of claim 1, wherein the four wheel steering system uses a yaw rate to steer the rear wheel in a direction in which the yaw rate decreases when the detection yaw rate is greater than or equal to a set value. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
