China's TPMS Market Is Expected to Reach 2.8 Billion Yuan in 2020

 

Tire pressure monitoring system (TPMS) is a device which can monitor tire pressure in real time and give an alarm when the tire leaks or the air pressure is too low to ensure driving safety.

 

1. Introduction

Tire pressure monitoring system can effectively prevent traffic accidents, prolong the service life of tires, reduce the wear of suspension system and improve fuel economy simultaneously.

 

2. Species

Tire pressure monitoring can be divided into two types according to different detection principles.

 

One is direct tire pressure monitoring. It installs a pressure sensor in each tire to directly measure the tire pressure. In case of any abnormality, the system will automatically alarm. Its main cost is transmitter + controller, and its application range is wide.

 

The other is indirect tire pressure monitoring. The working principle of indirect tire pressure monitoring system is to analyze the speed and radius of each wheel with ABS wheel speed sensor. When the tire pressure is abnormal, the rolling radius of the wheel will be smaller, resulting in its speed faster than other wheels. By comparing the speed difference between tires, the purpose of monitoring tire pressure can be achieved. Indirect tire pressure monitoring does not need additional parts and components, and the cost is low, but it needs to pay for software licensing fees and utilization fees. In some driving conditions, it can not accurately and safely monitor the tire pressure of each wheel.

 

3. At Present, the Penetration Rate of Domestic Tire Pressure Monitoring Is about 51% in China, and the Direct Type Accounts for 35-40%

Based on the analysis of the configuration data of 10946 models on sale in Auto House in China, it is found that there are 5616 passenger cars with the function of tire pressure monitoring (no distinction between direct and indirect), accounting for 51.3% of the total. And the proportion of passenger cars without tire pressure monitoring is about 48.7%.

 

The overall mandatory installation time of tire pressure monitoring in foreign countries is earlier, and its market structure is different due to the proportion of sales volume of different vehicle series. The North American automobile market is mainly American series and Japanese series vehicles, and the proportion of direct and indirect tire pressure monitoring is about 9:1. German cars account for a large proportion in the European market. Because German brand passenger cars use more indirect type, the proportion of direct and indirect types in Europe is about 6:4. The proportion of direct and indirect types in China is about 7:3, and the current direct penetration rate is expected to be 35% - 40%.

 

4. In 2020, China Began to Force the Full Installation of Tire Pressure Monitoring, and the Penetration Rate of Direct TPMS Is Expected to Increase to 70%.

Because of the importance of tire pressure monitoring system, together with air bag and ABS system, it constitutes the three major safety systems of automobile. In 2007, the U.S. fully forced installation and the EU fully implemented it since 2012.

 

With the development of automobile industry in China, the document‘performance requirements and test methods of passenger car tire pressure monitoring system’has been officially issued. The regulation requires that from January 1, 2020, all vehicles will be forced to install tire pressure monitoring system. The implementation of this mandatory policy has promoted the rapid improvement of TPMS penetration rate in 2019-2020. It is estimated that the penetration rate of direct TPM has increased from 40% in 2018 to 50% in 2019 and is expected to reach 70% in 2020. It is estimated that the domestic TPMS market scale in 2019-2020 will be 1.91 billion and 2.88 billion respectively, with growth rates of 13.44% and 47% respectively. And the direct TPMS related industry chain will also benefit from it directly.

 

The main structure of direct TPMS transmitter is composed of chip, battery, sensor and antenna. The chip accounts for 50-60% of the cost, and the electronic part accounts for 10-20%. The main chip suppliers are some foreign invested enterprises. Domestic enterprises mainly focus on TPMS integration.

Having the above knowledge of TPMS, you definitely know the importance of it, we can provide you with more than 95% platform of tpms, such as lexus tire pressure sensor, honda tpms sensor, toyota tire pressure sensor, bmw tire pressure sensor and so on.
