The primary function of an Automotive Tire Pressure Monitoring System (TPMS) in a car is to alert the driver when one or more tires are significantly underinflated, which can further lead to hazardous driving situations. The TPMS low tire pressure indication is displayed on the dashboard panel as a yellow light in the form of a cross-shaped tire (resembling a horseshoe) with an exclamation point. The anti-lock brake system uses wheel speed sensors, which are the foundation of an indirect TPMS.
Each wheel's revolution rate is recorded by these sensors, which are also employed by onboard computer systems for comparison. Automotive Tire Pressure Monitoring System (TPMS) is a system used to detect and track tire pressure in vehicles using wheel speed sensors like ESC and ABS or pressure sensors. In automobiles, TPMS are employed in two different ways: directly and indirectly. Additionally, it is frequently utilized in HCVs, LCVs, and passenger automobiles. Typically, tire pressure monitoring systems run on batteries, and batteries typically last 6–10 years.
