Tyres are important components in the operation of automobiles, and the updating and iteration of tire related technologies closely affect the development of automobile technology. At the same time, tires are also closely related to the safety and comfort of automobiles. In the era of intelligent electric vehicles, how can we achieve more intelligent and convenient tire management? The answers are provided by Sensata Technology's Tire Pressure Monitoring System (TPMS) and Intelligent Tire Management System (ITS).

　　Tire Pressure Monitoring System (TPMS)

　　The function of TPMS is to conduct real-time automatic monitoring of tire pressure during vehicle driving. When a tire leak is found or the tire pressure value is lower than the allowable normal working pressure limit, the TPMS alerts the vehicle control system to ensure driving safety. TPMS, as one of the three major automotive safety systems alongside airbag and anti lock braking systems, has been valued and recognized by the majority of automotive end users. In China, mandatory regulations for tire pressure monitoring systems have entered into force since 2019.

　　TPMS is divided into direct and indirect types. A direct TPMS is a system that installs tire pressure sensors in each tire, transmits data via wireless radio frequency, and displays the current tire pressure and temperature values on the vehicle's instrument. Indirect TPMS does not require the installation of physical sensors in each tire. Instead, it calculates and judges the wheel speed difference through the wheel speed sensor of the ABS system, thereby determining the underpressure of a certain tire.

　　Compared to direct TPMS, indirect TPMS has the advantage of low cost because there is no need to install physical sensors, and its disadvantages are also obvious. First, the system reaction speed of indirect TPMS is relatively slow, and second, the logic judgment conditions are complex, which can easily lead to false alarms.

　　Sensata Technology provides direct TPMS products and solutions that are widely used in various vehicle types, including motorcycles, passenger cars, light/heavy trucks, and the front and rear loading markets of non road construction machinery.

　　The product line of Sensata Technology can be divided into TPMS sensors with valves, tire mounted TPMS sensors, and receivers/controllers. TPMS sensors with valve type can be divided into two types according to installation methods: snap on type and press on type. The product line of Sensata Technology has fully covered the needs of all types of high, medium, and low end vehicles, and can be applied to regions with or without speed limits worldwide. In addition, Sensata Technology provides a flexible business model to adapt to the actual needs of different customers.

　　Intelligent Tire Management System (ITS)

　　With the continuous development of automobiles towards electrification, intelligent networking, and autonomous driving, more and more stringent requirements are put forward for the monitoring of tires and driving behavior. The new generation intelligent tire management system (ITS) from Sensata Technology is based on pressure and acceleration sensing technology, providing tire maintenance, remote monitoring, and vehicle condition monitoring for vehicles, providing key tire data and reassuring services to equipment manufacturers, tire manufacturers, and drivers.

　　The basic functions of ITS under Sensata Technology are mainly divided into four categories:

　　Category 1: Bluetooth transmission. ITS adopts low-power Bluetooth BLE technology, which can seamlessly integrate into the vehicle Bluetooth platform. At the same time, it has significantly improved the effectiveness and security of data transmission.

　　Category 2: tire ID identification. Tire ID is a tire ID identification that is the basis for a series of advanced functions of ITS.

　　Category III: tread depth monitoring. By integrating sensor data and relevant system data in the vehicle, combined with advanced algorithms, the monitoring of tire tread depth is achieved.

　　Category 4: Vehicle load measurement. It provides real-time feedback for the battery management system, estimates more accurate mileage, and also provides more accurate judgment basis for the auto drive system to adjust the braking distance.

　　Based on the four basic functions of the ITS platform, Sensata Technology has planned and developed a wealth of intelligent tire management value-added functions: inflation assistance, road condition monitoring, tire theft tracking, seasonal tire management, tire life management, and enhanced network security.

　　ITS can explore business opportunities and drive value realization in the four stages of the tire lifecycle.

　　The first stage: tire production stage. Based on the full stack of user behavior analysis provided by ITS, it is possible to further refine market segments such as regional and end-user groups, and optimize tire design accordingly. Big data based on tires can optimize the raw material supply chain and improve raw material turnover efficiency.

　　The second stage: tire transportation stage. Based on the big data analysis of ITS, the regional tire usage can be obtained to optimize inventory, improve operational efficiency, and optimize logistics costs.

　　The third stage: tire use stage. On the basis of traditional tire pressure sensors, ITS provides rich and customizable tire characteristic status detection functions. While comprehensively monitoring tire status, it can customize accurate service information push for end users, comprehensively improving the user experience.

　　Stage 4: Waste recycling stage. Based on ITS big data, it can accurately layout the waste tire recycling business.

　　The automotive industry is developing rapidly, and technological changes are changing with each passing day. The dual carbon strategy, new energy, intelligence, digitization, content-based, and driving experience represent the development direction of the automotive industry in the next few years. Sensata Technology is committed to providing customers with market leading product solutions, driving and leading market demand and business opportunities through sensor hardware, virtual sensors, and a combination of the two.
