What is tire pressure display

Tire pressure monitoring is real-time automatic monitoring of tire pressure while the car is running. The tire pressure display transmits the tire pressure value signal through the tire pressure monitoring sensor to the central control screen or tire pressure checker for display. It also sends an alarm for tire leaks and low air pressure to ensure driving safety.

　　

There are two main types of tire pressure monitoring for cars: one is indirect tire pressure monitoring, and the working principle of indirect tire pressure monitoring is that when the tire pressure decreases, the weight of the vehicle will make the rolling radius of the wheel smaller. So that its speed is faster than other wheels. The purpose of monitoring tire pressure is achieved by comparing the speed difference between tires. Indirect tire warning systems actually monitor air pressure by calculating the tire rolling radius. The other is direct tire pressure monitoring: Direct tire pressure monitoring equipment uses a pressure sensor installed in each tire to directly measure tire pressure, and uses a wireless transmitter to send the tire's pressure information to a central receiver module, which then displays the tire pressure data. When the tire pressure is too low or leaks, the system will automatically send out an alarm.
