Where is the tire pressure monitoring displayed on the Audi A4L?
1 Answers
The 2021 Audi A4L displays tire pressure on the control panel. There are three common methods of tire pressure monitoring: Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When tire pressure is too low or there is a leak, the system will automatically issue an alarm. Indirect tire pressure monitoring: When the pressure in a tire decreases, the weight of the vehicle will cause 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 purpose of monitoring tire pressure is achieved. Indirect tire pressure warning systems actually rely on calculating the rolling radius of the tires to monitor pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a four-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the defect of indirect systems being unable to detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires like a direct system.
