What is the Principle of Tire Pressure Monitoring?
2 Answers
The principle of tire pressure monitoring is as follows: 1. Indirect Tire Pressure Monitoring System: It monitors tire pressure by comparing the rotational speed differences between tires. 2. Direct Tire Pressure Monitoring System: It involves installing four tire pressure monitoring sensors inside the tires to automatically monitor tire pressure and temperature in real-time, whether the vehicle is stationary or in motion. It also provides timely alerts for high pressure, low pressure, and high temperature in the tires to prevent traffic accidents caused by tire failures, ensuring driving safety. Additional Information: The Tire Pressure Monitoring System is abbreviated as "TPMS," short for "tire-pressure-monitoring-system." This technology can automatically monitor various tire conditions in real-time by recording tire rotation speeds or using electronic sensors installed in the tires, providing effective safety assurance for driving.
As an auto mechanic, I've personally witnessed many accidents caused by tire pressure issues. The principle of tire pressure monitoring actually falls into two categories: direct and indirect methods. The direct method involves installing a small sensor inside the tire that can measure air pressure and temperature in real-time, then transmitting the data via wireless signals to a receiver in the vehicle, allowing you to view the readings on the dashboard. The indirect method doesn't require additional sensors but instead utilizes the wheel speed sensors of the Anti-lock Braking System (ABS); if a tire is leaking while driving, it will rotate slightly faster than the other tires, and the system triggers a warning upon detecting this speed difference. This design is clever in terms of cost-saving but isn't very precise. Overall, the principle relies on real-time monitoring to prevent blowout risks, extend tire lifespan, and reduce fuel consumption. Without this system, a minor leak could lead to major disasters, which is why I always remind my friends to regularly check their tire pressure—safe driving is more important than anything else.
