Abstract

본 발명은 자동차의 이상상태를 자동으로 판별하여 운전자에게 음성으로 경고하는 장치 에 관한 것으로서, 램프 감지 회로(1-1 ∼ 1-5)는 등화용 램프의 고장을 감지하여 등화램프고장신호를 출력 하고, 구동신호출력 회로 (2-1∼2-7)은 경고용 램프의 구동을 감지하여 경고램프구동신호를 출력 하며, 이상주행 감지회로(4)는 핸드 브레이크가 구동시에 발생되는 브레이크구동신호와 자동차주행시에 발생되는 주행속도표시용 펄스신호를 음성출력회로(5)에 인가한다.The present invention relates to a device for automatically detecting an abnormal state of a vehicle and warning the driver with a voice. The lamp detecting circuit (1-1 to 1-5) detects a failure of the lamp for lighting and outputs a lamp lamp failure signal. The driving signal output circuits 2-1 to 2-7 detect the driving of the warning lamp and output a warning lamp driving signal. The abnormal driving detection circuit 4 generates the brake driving signal generated when the hand brake is driven. And a driving speed display pulse signal generated at the time of driving the vehicle to the audio output circuit 5.

음성출력회로(5)는 이들 신호에 따라 소정 등화용 램프의 고장 또는 소정 경고용 램프의 구동 또는 핸드브레이크구동중의 자동차주행여부를 판단하여 이를 경고하는 내용을 음성으로 출력하므로 자동차사고의 예방 및 운전의 편리를 증대시키는 효과가 있다.According to these signals, the audio output circuit 5 determines whether or not the predetermined lamp is broken or whether the vehicle is being driven while driving the predetermined warning lamp or driving the hand brake. There is an effect of increasing the convenience of driving.
