Abstract

In this paper, a wireless measurement system has been developed which can measure the deformation of a tire in real time by utilizing strain gauge sensors and Zigbee wireless communication. A strain gauge sensor is mounted inside the tire and then the strain on the tire is obtained using the DSP module. The acquired sensor values are transmitted into the vehicle by radio communication. The wireless receiver module installed inside the vehicle can monitor the deformation of the tire in real time. The deformation of the tire can be used for measuring the load applied to each tire or the speed of the tire. The load or speed applied to the tires are essential parameters for the stable control of autonomous vehicles.

본 논문에서는 스트레인게이지 센서와 Zigbee 무선 통신 기술을 활용하여 차량 주행 시 타이어의 변형량을 실시간으로 측정할 수 있는 무선 계측시스템을 개발하였다. 차량 타이어의 내부에 스트레인게이지 센서를 장착하고 DSP 모듈을 이용하여 차량이 주행 중 발생하는 타이어의 변형량을 취득하였다. 취득된 센서 값은 무선 통신으로 차량 내부로 전송된다. 차량내부에 장착된 무선 수신 모듈은 타이어의 변형량을 실시간으로 모니터링 할 수 있도록 구현하였다. 이와 같이 취득된 타이어의 변형량은 각 타이어에 가해지는 하중 또는 타이어의 속도 측정에 이용할 수 있다. 타이어에 가해지는 하중 또는 속도는 자율주행자동차의 안정성 있는 제어를 위해서는 반드시 필요한 파라메타들이다.
