Tire pressure monitoring is a real-time automatic monitoring of tire pressure while the car is driving, and alarms for tire leakage and low air pressure. The tire pressure monitoring system is a type of active safety equipment that can provide timely alarms when dangerous signs appear in the tires. , reminding the driver to take appropriate measures.
Tire pressure monitoring is mainly divided into two types: indirect tire pressure monitoring and direct tire pressure monitoring:
Direct tire pressure monitoring device: It uses a pressure sensor installed in each tire to directly measure the tire pressure. It uses a wireless transmitter to send the pressure information from inside the tire to the central receiver module, and then analyzes the tire pressure data. show. When the tire pressure is too low or there is a leak, the system will automatically alarm.
Indirect tire pressure monitoring: When the air pressure of a tire decreases, the weight of the vehicle will cause the rolling radius of the wheel to become smaller, causing it to rotate faster than other wheels. By comparing the speed differences between tires, the purpose of monitoring tire pressure is achieved. The indirect tire warning system actually relies on calculating the rolling radius of the tire to monitor air pressure. (Pictures/Text/Photography: Xu Shuanghe of Pacific Automotive Network)
