Abstract: 본 발명은 차량을 운행 중 운전자에게 변속할 시기를 알려 주도록 하는 변속 경보 장치에 대한 것으로, 상세하게는 크랭크 샤프트에 부착시킨 센서에 의해 엔진 회전수와 상기 크랭크 샤프트의 진동폭을 동시에 감지토록 하고, 감지된 신호는 변환기를 통해 일정한 주파수 파형으로 변환시켜 증폭기에서 증폭되도록 하며, 증폭된 주파수 신호를 레벨 판독기를 통해 이미 기억된 신호값과 비교판단하여 경보 수단을 작동케 하므로서 변속 시기를 적기에 알려줄 수 있도록 한 엔진의 내구성을 향상시키면서 안전하고 조용한 운행이 될 수 있도록 하는 변속 경보 장치에 대한 것이다.
