Tire pressure monitoring system is abbreviated as TPMS. This technology can record the rotation speed of the tire or the electronic sensor installed in the tire to monitor the tire's various conditions in real time and automatically, which can provide effective security for driving.
1. Integration: With the development of electronic technology and manufacturing process, tire pressure monitoring system will be more portable and integrated in the future. This integration trend is mainly reflected in the integration of tire pressure monitoring module. By installing the pressure, temperature, acceleration sensor, 8-bit microprocessor and RF transmitting circuit in one chip, the total mass of the module is greatly reduced and the dynamic balance of tire is not damaged. The effective integration of the signal receiving module, alarm module and ECU of the monitoring system is also an important means for enterprises to promote the TPMS in the future.
2. Passivity: Battery life is another bottleneck that affects the normal operation of TPMS. When the tire is in a humid and harsh environment, the battery may leak electricity, resulting in a greatly reduced service life. Battery free power supply is another trend of TPMS industry in the future. In the future, the technologies that can realize passive TPMS include the following: using piezoelectric elements to convert the kinetic energy of tires into electrical energy, and storing it in capacitors. Through the external electromagnetic field, the energy is transmitted to the tire pressure sensor inside the tire, and the voltage and current are generated in the tire pressure sensor coil to provide energy for the measurement launch module.
3. Accuracy: Whether indirect or direct TPMS, improving the accuracy of tire pressure monitoring is an important way to determine the market share in the future. For indirect TPMS, the method to improve the alarm accuracy tends to improve the system algorithm. For direct TPMS, improving the detection accuracy of tire pressure sensor and anti-interference ability of wireless communication is an effective way to improve the accuracy of alarm. The wide use of MEMS sensors and the improvement of their performance have greatly improved the performance of the tire pressure sensor. In order to ensure the stability and reliability of wireless communication data transmission, measures must be taken to overcome the interference between signals.
4. Intelligence: At present, Michelin and Goodyear have installed pressure monitoring devices, temperature monitoring devices and signal transmitters in the tire wall during the tire manufacturing process, which will play a role throughout the tire life. The signal reception device can be made into a handheld decoding reader similar to a mobile phone, making it easy for drivers to use the device at any time. With the advent of smart tires and smart monitoring devices, future tire pressure monitoring will become more intelligent.
5. Integration: Integrate vehicle ECU, Global Positioning System, Geographic Information System, Intelligent Transport System and other technologies, and through the integration of hardware and software interfaces, can greatly promote the application of tire pressure monitoring system in the automotive field.
