Description

Wireless tire pressure detecting system capable of automatically positioning

Technical Field

The present invention relates to a wireless tire pressure detecting system capable of automatically positioning, and more particularly to a wireless tire pressure detecting system capable of automatically determining the position information of a tire mounted on a sensor.

Background

A Tire Pressure Monitoring System (TPMS) generally includes a plurality of tire pressure detecting devices mounted on tires of a vehicle (vehicle), and a device for detecting whether each tire has an abnormal tire pressure. Since the 1980 s, tire pressure detecting devices have been installed in some of the european vehicle models. In recent years, the united states, european union and korea have regulated that all new vehicles must be equipped with a tire pressure detecting device to ensure driving safety. However, japan, china and india are also expected to implement relevant regulations in the near future. Taiwan also stipulates that automobiles produced 7 months after 2016 are required to be equipped with a tire pressure detecting device.

In the driving of the vehicle, the tire pressure is a very important factor for the driving safety. If the tire pressure of the tire is insufficient, the contact area between the tire skin and the ground is increased, so that the friction force between the tire and the ground is increased, the oil consumption is increased, and the load of an engine is increased; in addition, the temperature of the air inside the tire will also rise, with the volume expansion of the air, and if the tire condition is not good, the tire may even burst. Therefore, in order to make the driver able to control the tire pressure of the tire, so as to slow down the speed of the vehicle when detecting the abnormal tire pressure during driving, and stop the vehicle at the roadside to avoid traffic accidents, the conventional wireless tire pressure detector can be installed in the tire of the vehicle, and the wireless tire pressure detector detects the tire pressure of the tire and transmits the detection result to a display unit, so that the driver can view the state of the tire pressure at any time.

In the case of a four-wheel car, four tires are respectively equipped with a wireless tire pressure detector, and the tires can be divided into two front wheels and two rear wheels, or two left wheels and two right wheels according to the direction. For example, because the front wheel is closer to the engine, the tire temperature of the front wheel is generally higher than that of the rear wheel, and therefore the receiving device can determine whether the tire disposed on the wireless tire pressure detector is the front wheel or the rear wheel according to the tire temperature. However, the tire temperature characteristics of the left and right tires are similar, and it cannot be directly determined whether the tire installed in the wireless tire pressure detector is the left tire or the right tire according to the tire temperature.
