Abstract
1. 청구범위에 기재된 발명이 속하는 기술분야1. TECHNICAL FIELD OF THE INVENTION
차량의 저타이어 압 경고장치의 제어방법.Control method of low tire pressure warning device of vehicle.
2. 발명이 해결하려고하는 기술적 과제2. The technical problem that the invention is trying to solve
타이어의 압력이 일정압력 이하로 저하되었을 경우에 이를 운전자에게 경고하여 운전자가 저타이어압 상태를 신속하게 인지하도록 함으로써 운전자로 하여금 타이어의 관리를 보다 효율적으로 할 수 있도록 함.When the tire pressure drops below a certain pressure, the driver is alerted so that the driver can recognize the low tire pressure quickly so that the driver can manage the tire more efficiently.
3. 발명의 해결방법의 요지3. Summary of Solution to Invention
바퀴의 회전속도를 감지한 뒤에 이를 전기적인 신호로 변환하여 출력하는 휠 스피드 센서부(10)와, 트랜스미션축의 회전속도를 감지한 뒤에 이를 전기적인 신호로 변환하여 출력하는 주행속도센서부(20)와, 상기한 휠스프드The wheel speed sensor unit 10 detects the rotational speed of the wheel and converts it into an electrical signal and outputs it, and the driving speed sensor unit 20 detects the rotational speed of the transmission shaft and converts it into an electrical signal and outputs the electrical signal. Wow, above mentioned wheelspan
센서부와 주행속도 센서부로부터 입력되는 애널로그 신호를 디지틀 신호로 변환하여 출력하는 애널로그/디지틀 변환부(30)와, 상기한 애널로그/디지틀 변환부에서 입력되는 신호로부터 주행속도에 대응하는 기준 휠속도와 실제An analog / digital converter 30 for converting an analog signal input from the sensor unit and the traveling speed sensor unit into a digital signal and outputting the analog signal; and a signal corresponding to the traveling speed from the signal input from the analog / digital converter. Reference wheel speed and actual
휠속도를 산출한 뒤에, 기준 휠속도와 실제 휠속도의 차이가 일정치 이하인 경우에는 저타이어압 상태임을 경고하기 위한 신호를 출력하는 제어부(40)와, 상기한 제어부로부터 신호가 입력되면 운전자에 경고 메시지를 출력하는 경고 표시부(50)를 포함하여 이루어짐.After the wheel speed is calculated, if the difference between the reference wheel speed and the actual wheel speed is less than a predetermined value, the controller 40 outputs a signal to warn that the vehicle is in a low tire pressure state. It comprises a warning display unit 50 for outputting a warning message.
4. 발명의 중요한 용도4. Important uses of the invention
타이어의 압력이 일정압력 이하로 저하되었을 경우에 이를 운전자에게 경고하여관리를 보다 효율적으로 할 수 있도록 함.It alerts the driver when the tire pressure drops below a certain pressure for more efficient management.
