How Many Types of Tire Pressure Monitoring Systems Are There?
1 Answers
Here is a detailed introduction to tire pressure monitoring methods: 1. Direct Tire Pressure Monitoring System (TPMS). The direct TPMS uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure data for each tire. When the tire pressure changes, the information is directly fed back to the driver. 2. Indirect Tire Pressure Monitoring System. The indirect TPMS determines whether tire pressure has decreased by detecting differences in tire rotation speed. When the pressure in a tire drops, the vehicle's weight causes the rolling radius of that wheel to decrease, resulting in a faster rotation speed compared to other wheels. When tire pressure drops, only a warning symbol is displayed. 3. Hybrid TPMS. This system installs sensors in two diagonally opposite tires and is equipped with a 4-wheel indirect system. Compared to a full direct system, this hybrid system can reduce costs and overcome the limitation of indirect TPMS, which cannot detect simultaneous air leaks in multiple tires. However, it still cannot provide real-time data on the actual pressure in all four tires like a direct TPMS.
