Description
本發明細關於一種可自動定位的無線胎壓偵測系統，尤指一種可自動判斷傳感器所安裝輪胎的位置資訊。 The invention relates to a wireless tire pressure detection system capable of automatic positioning, in particular to a kind of information capable of automatically judging the position of the tire installed by the sensor.
胎壓偵測系統(tire pressure monitoring system,TPMS)通常包含裝設於動力裝置(vehicle)的輪胎上的多個胎壓偵測裝置，用於偵測各輪胎是否有胎壓異常的裝置。自從1980年代，胎壓偵測裝置就已經設置在歐洲的部分車款。近年來，美國、歐盟與韓國已經規定所有新車必須裝設胎壓偵測裝置以確保駕駛安全性。而日本、中國大陸與印度也預計要在不久的未來實施相關的規定。臺灣也規定2016年7月以後生產的汽車均須裝設有胎壓偵測裝置。 A tire pressure monitoring system (TPMS) generally includes a plurality of tire pressure detection devices mounted on a tire of a vehicle, and is used to detect whether each tire has an abnormal tire pressure. Since the 1980s, tire pressure detection devices have been installed in some European models. In recent years, the United States, the European Union, and South Korea have stipulated that all new cars must be equipped with tire pressure detection devices to ensure driving safety. Japan, China and India are also expected to implement relevant regulations in the near future. Taiwan also stipulates that cars manufactured after July 2016 must be equipped with tire pressure detection devices.
而在車輛行駛中，輪胎胎壓是行車安全相當重要的一因素。若輪胎胎壓不足，輪胎表皮與地面的接觸面積增加而提高輪胎與地面的磨擦力，導致增加油耗以及加重引擎負擔；此外，輪胎內部的空氣溫度也將上升，伴隨空氣體積膨脹，若輪胎胎況不佳，嚴重時甚至出現爆胎的情況。因此，為了使駕駛人能掌握輪胎胎壓，以便於行駛中察覺胎壓異常時減慢車速，將車輛停靠路邊避免衍生交通意外，現有無線胎壓偵測器可供裝設在車輛的輪胎中，由無線胎壓偵測器偵測輪胎的胎壓，並將偵測結果傳送到一顯示單元，供駕駛人可隨時檢視胎壓狀態。 In vehicle driving, tire pressure is a very important factor for driving safety. If the tire pressure is insufficient, the contact area between the tire skin and the ground increases, which increases the friction between the tire and the ground, resulting in increased fuel consumption and increased engine load. In addition, the air temperature inside the tire will also rise, accompanied by air volume expansion. The condition is not good, and even a flat tire may occur in severe cases. Therefore, in order to enable the driver to grasp the tire pressure, so as to slow down the speed when the tire pressure is abnormal during driving, and park the vehicle at the roadside to avoid traffic accidents, the existing wireless tire pressure detector can be installed on the tire of the vehicle In the wireless tire pressure detector, the tire pressure is detected by the wireless tire pressure detector, and the detection result is sent to a display unit for the driver to check the tire pressure status at any time.
以四輪轎車為例，其四個輪胎皆分別裝設有一無線胎壓偵測 器，依據方位可將輪胎區分為兩個前輪與兩個後輪，或兩個左輪與兩個右輪。前、後輪的判斷方式較為容易，舉例來說，因前輪距離引擎較近，一般而言，前輪的胎溫會高於後輪的胎溫，故該接收裝置可根據胎溫高低判斷無線胎壓偵測器所設置的輪胎為前輪或後輪。然而，左、右輪的胎溫特性較為雷同，若僅依據胎溫高低無法直接判斷出無線胎壓偵測器所裝設的輪胎是左側輪胎或右側輪胎。 Take a four-wheeled car as an example, each of its four tires is equipped with a wireless tire pressure detection According to the orientation, the tire can be divided into two front wheels and two rear wheels, or two left wheels and two right wheels. The front and rear wheels are easier to judge. For example, because the front wheels are closer to the engine, in general, the tire temperature of the front wheels will be higher than the tire temperature of the rear wheels, so the receiving device can judge the wireless tire based on the tire temperature. The tires set by the pressure detector are front wheels or rear wheels. However, the tire temperature characteristics of the left and right wheels are more similar. If the tires installed by the wireless tire pressure detector cannot be directly judged whether they are left or right tires based only on the tire temperature.
故，本發明之目的，即在提供一種可自動定位的無線胎壓偵測系統，尤指一種可自動判斷傳感器所安裝輪胎的位置之無線胎壓偵測系統。 Therefore, the purpose of the present invention is to provide a wireless tire pressure detection system capable of automatic positioning, in particular to a wireless tire pressure detection system that can automatically determine the position of the tire mounted on the sensor.
