Where is the tire pressure monitoring system installed?
1 Answers
Automotive tire pressure monitoring systems are installed either inside the tires or on the exterior of the valve stems. The tire pressure monitoring system continuously and automatically monitors tire pressure during vehicle operation, alerting drivers to air leaks or low pressure to ensure driving safety. There are three common types of tire pressure monitoring methods: Direct tire pressure monitoring: Direct systems use pressure sensors installed in each tire to directly measure air pressure. Wireless transmitters send pressure data from inside the tires to a central receiver module, which then displays the pressure readings for each tire. The system automatically alerts when tire pressure is too low or when there's an air leak. Indirect tire pressure monitoring: When a tire's pressure decreases, the vehicle's weight causes that wheel's rolling radius to become smaller, making it rotate faster than other wheels. By comparing rotational speed differences between tires, the system monitors pressure. Indirect systems essentially rely on calculating tire rolling radius to monitor pressure. Tire Pressure Monitoring System (TPMS) introduction: This hybrid system combines advantages of both systems mentioned above. It installs direct sensors in two diagonally opposite tires while using a 4-wheel indirect system. Compared to full direct systems, this composite design reduces costs and overcomes the indirect system's inability to detect simultaneous low pressure in multiple tires. However, it still cannot provide real-time pressure data for all four tires like direct systems can.
