Abstract

Most cars today use electronic control to control the state of the engine to achieve optimum performance. This study developed a device for maintaining fault diagnosis and optimal vehicle status by displaying the engine information of a car on the screen in real time using can communication. This system displays information generated from the engine to the driver in real time such as engine intake and exhaust temperature, current battery voltage, tire pressure, RPM, DPF collection amount, torque, and horsepower through the OBD2 socket. You can check immediately. It can help you to drive safely by measuring tire pressure and displaying it on the screen, and it provides a mode to set the shift timing to suit your taste. In particular, in the case of diesel engine cars, the problems caused by smoke can adversely affect the performance and environmental pollution. Therefore, the system was developed to display the DPF collection amount on the system screen to prevent environmental pollution and to manage the vehicle efficiently.

오늘날 대부분의 자동차는 전자제어를 통하여 엔진의 상태를 제어하여 최적의 성능을 얻을 수 있도록 하고 있다. 본 연구는 캔통신을 이용하여 자동차의 엔진의 정보를 운전자에게 실시간으로 화면에 표시하여 고장진단과 최적의 자동차 상태를 유지하는 장치를 개발하였다. 이 시스템은 엔진에서 발생되는 정보를 OBD2 소켓을 통하여 엔진의 흡배기온도, 현재 배터리 전압, 타이어 공기압, RPM, DPF 포집량, 토크, 마력 등의 정보를 실시간으로 운전자에게 표시하여 운전자가 차량의 상태를 즉시 확인이 가능하다. 타이어의 공기압을 측정하여 화면에 표시하여 안전운행에 도움을 줄 수 있으며, 자신의 취향에 맞도록 변속타이밍을 설정할 수 있는 모드를 제공한다. 특히 디젤엔진 자동차의 경우 매연으로 인한 문제는 자동차 성능과 환경오염에 악영향을 미칠 수 있으므로 시스템 화면에 DPF 포집량을 표시하여 환경오염 방지와 효율적인 자동차 관리를 할 수 있도록 시스템을 개발하였다.
