Tire pressure sensor is a device installed in the car tire, which can detect the tire pressure and temperature in real time, and transmit specific communication information to the receiver in the car in the form of RF. The driver can know the current condition of the tire through the tire pressure sensor to reduce the accident probability. In addition to safety, TPMS can improve fuel economy efficiency by about 2% on average, reduce carbon dioxide emissions, and save fuel consumption and environmental protection. These factors are also one of the important reasons for countries to implement TPMS as standard equipment.
The traditional tire pressure sensor is one-to-one type, which is mainly designed for the specific original vehicle type and mainly supplied to the OE market. Each sensor has a unique ID code. However, in the AM market, tire pressure sensors cannot be detected due to different sensor specifications. Therefore, the application of one-to-one tire pressure sensors for different types of vehicles is likely to cause a substantial increase in the inventory of the tire pressure sensor system(RF coding device for TPMS) in tire factory, and then universal type tire pressure sensor was born. Universal type tire pressure sensors are mainly supplied to AM market because they can detect different types of vehicles, and the main technology is to update and decode in the Internet cloud and burn in the blank sensors.
The United States is the first country in the world to legislate TPMS as standard equipment, which was passed in September 2005 and listed as 100% standard equipment in 2007. Generally speaking, the service life of tire pressure sensor is about 5-10 years. Based on the past sales of new cars in North America, an average of 50 million tire pressure sensors can be sold every year. It is estimated that the tire pressure sensors on OE market in the United States will maintain a stable growth every year.
TPMS regulations usually impose‘hard rules’on TPMS listed as standard equipment for the new car market. Therefore, the demand for TPMS on OE market is highly correlated with the supply of new cars every year. Compared with AM market, the‘potential rules’can only be followed without TPMS, which requires the tire repairers to consciously abide by them. Due to the lack of mandatory AM in the United States, it is still necessary for am practitioners to wait for the revision of AM by laws and regulations. In addition, the replacement demand of new car market in the future will be the growth point of TPMS practitioners in the future.
In addition to the U.S. market, the EU started legislation to promote TPMS in November 2012, and in November 2014, tire pressure sensors were listed as standard equipment. Based on the estimated annual sales of 10 million new cars in the EU, the market demand for OEM is about 40 million.
In Asia, the timing of TPMS legislation is ripe. Japan, South Korea, China and India have adopted similar legislation procedures to list tire pressure sensors as standard equipment. Therefore, the annual demand for tire pressure sensors in the OE market in Asia is about 160-220 million, which will become the largest TPMS new car market in the world.
In the U.S. market, after the financial storm in 2008, the consumption was tight, the number of years of use of automobile in the after market increased significantly every year, and the proportion of used cars in the U.S. for more than seven years continued to increase. The opportunity for replacing tire pressure sensors in the AM market in the U.S. was huge.
The National Highway Traffic Safety Administration (NHTSA) has launched a new specification for TPMS of after market.
(1) It is required that any auto maintenance plant shall not cancel TPMS functions and services for customers at will.
(2) For any special tire (e.g. snow tire), the vehicle repairer shall provide the service of replacing and installing TPMS sensor, or the new tire must be installed with TPMS sensor.
(3) If the repair shop is repairing the tire and accidentally makes the TPMS sensor out of order, it is necessary to change it to the customer immediately, otherwise it is also against the regulations.
(4) If the car has been handed over to the consumer to drive away and TPMS failure mode is on, it is not against the rules.
The demand of TPMS market in the United States changes with the sales of new cars every year. Because there are few TPMS suppliers in OE market, the revenue performance is linked with the sales of new cars. According to the market share analysis of TPMS in the OE market of the United States, SCHRADER is 50%, PACIFIC 22%, CONTI 10%, TRW 10% and BERU 8%. Among them, SCHRADER, the industry leader, is the first company to develop TPMS technology in the world. In 2011, the market share of global OE market exceeded 50%. That is to say, the annual sales exceeded 160 million TPMS sensors. It is mainly supplied to GM, Ford and other top cars. Pacific, the second largest player in the market, supplies Toyota and Honda.
