Abstract
본 발명은 차속 및 주행 도로의 노면 상태에 따라 자동으로 타이어의 공기압을 가감하는 타이어 공기압 조절장치에 관한 것이다. 타이어가 끼워진 휠(1)에는 공기 통로(2, 3)를 개폐하는 솔레노이드밸브(4)가 설치된다. 공기 통로의 주입구(2)에는 에어 펌프가 연결된다. 상기 솔로노이드밸브와 에어 펌프의 동작은 ECU에 의해 제어된다. 이 ECU는 주행 속도를 측정하는 차속센서와, 차체의 상, 하 진동을 측정하는 중력센서와, 타이어 내부의 공기압을 측정하는 압력센서와 연결된다. 이에 따라, 상기 ECU는 차속센서와 중력센서로부터 검출된 시그널을 비교, 분석하여 현 주행 차량의 속도 및 노면 상태를 판단한다. 이 ECU는 그 차량의 속도 및 노면 상태에 따라 정해진 규정의 공기압과 압력센서의 측정값을 비교하여, 상기 솔레노이드밸브와 에어 펌프를 작동시켜 타이어의 공기압을 자동으로 조절함으로써, 차량의 주행 안전성과 승차감을 향상시킨다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a tire air pressure regulating device for automatically increasing or decreasing an air pressure of a tire according to a road surface condition of a vehicle speed and a traveling road. A solenoid valve (4) for opening and closing the air passages (2, 3) is provided in the wheel (1) fitted with the tire. An air pump is connected to the inlet 2 of the air passage. The operation of the solenoid valve and the air pump is controlled by the ECU. The ECU is connected to a vehicle speed sensor that measures the running speed, a gravity sensor that measures the up / down vibration of the vehicle body, and a pressure sensor that measures the air pressure inside the tire. Accordingly, the ECU compares and analyzes the signals detected from the vehicle speed sensor and the gravity sensor to determine the speed and road surface condition of the current traveling vehicle. The ECU compares the measured air pressure of the pressure sensor with the prescribed air pressure determined according to the speed and road surface condition of the vehicle, and operates the solenoid valve and the air pump to automatically adjust the air pressure of the tire, .
