Abstract

이 발명은 후진 주행중 전진 변속 금지장치 및 그 방법에 관한 것으로, 변속레버 위치에 따른 전기적인 신호를 출력하는 인히비터 스위치(10)와, 차속을 감지하여, 그에 따른 전기적인 신호를 출력하는 차속 감지부(20)와, 상기 인히비터 스위치(10)로부터 출력되는 신호가, 변속레버의 상태가 후진이고, 상기 차속 감지부(20)로부터 출력되는 신호가 일정 차속 이상인 경우, 변속레버 잠금신호를 출력하는 제어부(30)와, 상기 제어부(30)로부터 출력되는 신호에 따라 동작하여, 변속레버가 움직이지 못하도록 하는 변속레버 잠금장치(40)로 이루어져 있으며, 자동변속기가 장착된 차량에 있어서, 후진 주행을 하다가, 전진 주행을 하려는 경우, 후진 주행시 차속이 일정 속도 이하로 떨어지기 전에는, 변속레버를 'D'레인지나, '2'레인지, 또는 'L'레인지 등 전진 주행방향으로 움직이지 않도록 하여 자동변속기를 보호하는 후진 주행중 전진변속금지 장치 및 그 방법에 관한 것이다.The present invention relates to a forward shift prohibiting device and a method thereof while driving backward, an inhibitor switch 10 for outputting an electric signal according to a shift lever position, and a vehicle speed detection for detecting a vehicle speed and outputting an electric signal accordingly. The shift lever lock signal is output when the state of the shift lever is reverse and the signal output from the vehicle speed detection unit 20 is greater than or equal to a predetermined vehicle speed. And a shift lever locking device 40 operating according to a signal output from the controller 30 and preventing the shift lever from moving. If you want to drive forward, move the shift lever to the 'D' range, '2' range, or 'L' range before the vehicle speed drops below a certain speed. And so as not to move in a direction related to reverse while the vehicle is being driven forward speed change prohibition device and a method of protecting the automatic transmission.
