According to statistics, the proportion of the vehicles caused by tire burst in the malignant traffic accidents is up to 70%, and the tire pressure insufficiency is the primary reason among all factors causing the tire burst. With the development of the automobile industry, more and more automobile types are carried with a tire pressure monitoring system. The state issues a standard GB27149 in 2017, and the tyre pressure monitoring system is required to be installed on the type M1 vehicle.
The mainstream tire pressure monitoring systems in the market at present are divided into direct tire pressure monitoring systems and indirect tire pressure monitoring systems. The indirect tire pressure monitoring mainly monitors the tire pressure state of the tire in real time through processing signals of a vehicle wheel speed sensor and the like, indirectly and accurately deduces the tire under-pressure position and gives an alarm so as to ensure the driving safety.
In view of the fact that the current indirect tire pressure monitoring system needs to be self-learned based on standard tire pressure to ensure accurate alarm, the tire pressure monitoring system needs to be reset after replacing tires or inflating again. In general, a tire pressure monitoring reset interface is arranged on a central control DVD screen or an instrument liquid crystal screen, and a user can reset the tire pressure monitoring reset interface. With the release of national standards for mandatory installation of tire pressure monitoring, some low-end vehicle models face a replacement scheme option.
