Where Can Tire Pressure Be Monitored?
1 Answers
Tire pressure monitoring devices vary based on the installation location of the sensors. Common tire pressure monitoring devices are usually found in the vehicle's onboard computer, while others may be located on the central console. The methods for monitoring tire pressure are as follows: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted wirelessly from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system will automatically issue an alert. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring Systems (TPMS): TPMS combines the advantages of both systems mentioned above. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires, as a direct system can.
