Abstract:
Tire Pressure Monitoring System (TPMS), which is a type of wireless communication device used in vehicles, is a safety aid system designed to prevent tire-related accidents in advance by regularly checking tire pressure and temperature and notifying the driver about any abnormality through its display. TPMS sensor unit in a tire contains sensors to measure the temperature and pressure and transmits the measured data to the signal processing unit in a vehicle via wireless communication. For the conventional TPMS, there is unnecessary power consumption in the sensor unit because of continuous transmission of the measured data from the tire to the signal processing unit at a regular interval. In this paper, we propose the low-power TPMS communication technique in which the signal processing unit in the vehicle transmits optimal tire pressure and threshold values based on the road condition and external temperature to the sensor unit in the tire. The sensor unit compares the measured data value with the optimal tire pressure value received from the signal processing unit and it sends the measured tire pressure data to the signal processing unit only if the difference between the values exceeds the threshold value. When the difference between both values is smaller than the threshold value, the sensor unit recognizes it as normal mode and transmits a normal mode bit to the signal processing unit. The performance of the proposed low-power TPMS communication technique is verified through computer simulation example.
