In accordance with the performance requirements and test methods of the car tire air pressure monitoring system, previously approved by the national standardized management committee, the requirements for the mandatory installation of tpms (treasure pressure monitoring system) will be implemented in all production vehicles from 1 january 2020。

Tpms and safety airbags and abs systems constitute the three main vehicle safety systems that effectively prevent traffic accidents. Many countries and regions, such as the united states and the european union, have legislation to enforce tpms because of the impact on vehicle safety of large or low tyres。
Tpms are divided into three categories: direct, indirect and hybrid. In this case, the direct tpms selects a pressure sensor fixed in each wheel to measure the pressure of the tyre directly, using wireless transmitters to send pressure information from inside the tyre to the system on the central receiver module, and then to monitor the pressure data of the tyres. When tyres are too low or leaky, the system automatically alerts the police and allows the driver to see if the wheel is abnormal through the tire count of each tyre。

Indirect tpms are used in conjunction with the vehicle's death protection system (abs), which works on the basis that when the pressure of a tyre is reduced, the weight of the vehicle reduces the rolling radius of the wheel, resulting in its speed being faster than that of the other wheels, and achieves the purpose of monitoring the tire pressure by comparing the speed differential between tyres. Its disadvantage is that it does not show which tyre is in a state of high and low pressure and therefore has some limitations。
The hybrid tims would require the installation of two additional tyre pressure sensors and a radio frequency receiver in the system to monitor the state of each tyre, but would be deficient in the reliability and flexibility of the system and would not be suitable for the back-loading market。

The tpms mandatory installation regulations, which have been in force since 1 january 2020, will result in a significant increase in demand for the relevant market for foetal pressure monitoring. According to industry sources, the implementation of mandatory policies will lead to a rapid increase in foetal pressure monitoring penetration rates between 2019 and 2020, with the market size of the tpms sector expected to reach 2,683 million yuan in 2019 and 4,378 million yuan in 2020, respectively. Among the most noteworthy in this area are the companies involved in car sensor operations, such as the four-direct charts new, the polytechnic, and the winning electronics. (van/car home )
