Automobile tire pressure mandatory standards will be in the near future

The latest automobile tire pressure related regulations have reached the end of brewing and are expected to be launched soon. According to the source, the new regulations set mandatory standards for tire pressure, that is, automobile manufacturers must install tire pressure monitoring systems on vehicles in accordance with relevant requirements.

Tyre pressure monitoring system effectively ensures safe driving

As a leading enterprise in automotive electronics such as sensors and electronic protectors, Chang Yan, President of China and India in Sensata Electronic Technology Co., Ltd. explained to reporters that the installation of a tire pressure monitoring system on vehicles is used on one hand for tires and automobiles. The need for energy conservation in the process, on the other hand, is to ensure the safety considerations during driving.

Chang Hao said that tire pressure is not only related to the comfort of driving, but also related to the safety of driving. If the tire pressure is too high, the friction and adhesion of the tire will be reduced, and the hidden danger of puncture tire will be formed, which will affect the safety of driving; the low tire pressure will not only cause the direction to sink, the deviation and other unfavorable driving safety factors, but also Damage to the tire.

According to public statistics, the number of car accidents caused by punctures is very high in the vicious traffic accidents, and the tire pressure caused by punctures is not the first reason.

It is understood that the automobile tire pressure monitoring system has been implemented for more than three years as the recommended standard for the automotive industry in China, and is installed in high-end and some mid-range vehicles, but the overall assembly rate is low. The data show that the assembly rate in 2012 was only 9.65%. Therefore, people in the industry believe that it is necessary to regulate the relevant tire pressure standards.

Sensor companies are expected to benefit

Industry sources said that currently China's tire pressure monitoring system mainly includes direct tire pressure monitoring system and indirect tire pressure monitoring system. Among them, the direct tire pressure monitoring device uses a pressure sensor installed in each tire to directly measure the tire air pressure, and uses a wireless transmitter to send pressure information from the inside of the tire to the system on the central receiver module, and then to each tire. Pressure data is monitored. When the tire pressure is too low or leaks, the system will automatically alarm. Even if the tires are slowly dispelled, the direct tire pressure monitoring system can be sensed by the driving computer, allowing the driver to directly inspect the tire pressure figures of the four tires from the driver's seat, thus real-time understanding of the real pressure condition of the wheels.

The working principle of indirect tire pressure monitoring is that when the pressure of a tire is reduced, the weight of the vehicle will make the wheel's rolling radius smaller, resulting in faster rotation speed than other wheels, so that it can be used to compare tires. Speed ​​difference, to achieve the purpose of monitoring tire pressure.

Chang Hao said that if tire pressure monitoring is implemented as a mandatory standard for automobiles, the demand for related sensor markets is expected to increase significantly, and the space in the automotive aftermarket is expected to open. With the advent of new standards, automotive tire companies are also expected to work with related sensor companies to seek greater profit margins.
