Tire pressure sensor (TPMS sensor) is a core component in modern automotive safety systems, mainly used to monitor tire pressure and temperature in real time, ensure driving safety, improve vehicle performance, and reduce usage costs through warning mechanisms.

The following is a detailed analysis of its specific function and principle

1、 Core functions and working principles

Real time monitoring and early warning

The direct sensor (high-precision) is installed inside the tire, and the pressure signal is converted into an electrical signal through a bridge type electronic pressure sensing device, which is wirelessly transmitted to the in car receiver to display real-time tire pressure and temperature data.

When abnormalities are detected (such as low air pressure, high air pressure, or excessive temperature), the system will alert the driver through sound and light alarms.
 

Indirect sensors indirectly determine tire pressure abnormalities through differences in wheel speed, but their accuracy is low and they cannot locate specific tires.
 

Preventing tire blowout accidents

Abnormal tire pressure (either too high or too low) is one of the main causes of tire blowouts. Sensors can detect potential hazards in advance, such as overheating of the tire sidewall when the tire pressure is low or decreased grip when the tire pressure is high, thereby avoiding the risk of loss of control during high-speed driving.

2、 Extended Value

Improve fuel economy

Maintaining standard tire pressure can reduce rolling resistance and lower fuel consumption. Data shows that fuel consumption may increase by 3% -5% when tire pressure is low.

Extend tire life

Appropriate tire pressure ensures even tire wear, avoids excessive local wear, and can extend the service life by 15% -20%.

Optimize vehicle performance

Ensure optimal grip and handling stability, especially in emergency braking or complex road conditions such as slippery surfaces.
