TPMS is great significance for the safety management of automobiles

Tire pressure monitoring system (TPMS) is an important automotive safety accessory that can monitor the tire pressure and temperature in real time, prevent dangerous states such as tire leakage, low pressure, high pressure, and high temperature, and ensure driving safety. TPMS is mainly divided into two types: indirect TPMS monitors tire pressure by comparing differences in wheel speed, while direct TPMS installs pressure sensors in each tire to directly measure air pressure and send data wirelessly.

The benefits of TPMS include effectively preventing tire blowouts, avoiding tire damage caused by low gas driving, reducing fuel consumption, ensuring optimal vehicle handling performance, and avoiding abnormal wear and tear of vehicle components. However, there may also be some issues with the TPMS system, such as incorrect detection data, inability to update data in real-time, mobile app related problems, and screen display issues.

In China, starting from January 1, 2019, all newly certified passenger cars must be equipped with TPMS, and from January 1, 2020, all in production passenger cars will be subject to mandatory installation requirements. With the development of technology, TPMS systems are moving towards integration and wireless passivity, which may enable passive measurement and wireless transmission of intelligent tire information in the future.

At present, the global TPMS chip market is mainly dominated by international semiconductor manufacturers such as Infineon, NXP, and GE, but domestic manufacturers such as Guangdong Hewei, Wanjie Electronics, and Jiefa Technology under NavInfo are also rising and striving to achieve domestic substitution. As the core component of TPMS system, the development trend of TPMS chip is low power consumption and high integration to improve the reliability and functional richness of the system.

In addition, TPMS sensors can be networked through wireless gateways to improve data transmission efficiency and achieve remote monitoring and data analysis, which is of great significance for the safety management of automobiles
