What is the principle of the built-in tire pressure monitoring system in cars?

The principle of the built-in tire pressure monitoring system in cars is: utilizing wireless transmission technology, it employs highly sensitive miniature wireless sensors to collect data such as tire pressure and temperature, whether the vehicle is in motion or stationary. This data is then transmitted to the main unit, which displays the tire pressure and temperature in real-time in a digital format. In case of any abnormalities in the tire, the system alerts the driver through beeping sounds or voice warnings. The tire pressure monitoring system provides safe and effective protection for driving, directly reflecting the condition of the car tires, effectively preventing tire blowouts, and avoiding tire damage caused by driving with insufficient air pressure.
I'm a car enthusiast and often study various vehicle intelligent systems. There are mainly two principles for tire pressure monitoring: direct tire pressure monitoring and indirect tire pressure monitoring. Direct tire pressure monitoring involves installing a small sensor inside each tire, which measures tire pressure data in real time and transmits the information to the car's computer system via wireless signals. If the tire pressure is low, a warning light on the dashboard alerts me. Indirect tire pressure monitoring uses wheel speed sensors to detect changes in tire rotation speed. If a tire is underinflated, it will rotate faster, and the system will trigger an alarm upon detecting abnormalities. I think direct monitoring is more accurate, but the sensors require battery replacement, while indirect monitoring is simpler but prone to false alarms. This system helps prevent tire blowouts and improves driving safety, especially on highways. It also saves me a lot on fuel costs because maintaining proper tire pressure reduces fuel consumption. Overall, modern cars come standard with this feature, reflecting technological progress, but it also reminds me not to rely solely on the system and to check tire pressure regularly.
As a safety-conscious driver, I've driven many cars and found that tire pressure monitoring is literally a lifeline. Its principle involves built-in sensors in the vehicle or monitoring wheel speed changes to detect abnormal tire pressure. For example, sensors installed inside the tires measure air pressure and send signals when it's too low, or ABS sensors check if a tire is rotating too fast. This quickly alerts me to insufficient tire pressure, preventing skidding or blowout accidents. I once experienced the system alerting me while driving in the rain, and fortunately, I stopped in time to check the tire pressure, avoiding danger. This system isn't just technology; it's a guardian angel for safety, mandated by regulations for all new vehicles. I'd advise every car owner to learn how to use it because it's as simple as responding when the dashboard light comes on. During routine car maintenance, it's good to ask the mechanic about related matters to ensure the system functions properly.
