Abstract

The invention provides a tire pressure monitoring system self-adapted to altitude. The tire pressure monitoring system at least comprises a sensor module, a receiver and an air pressure sensor, wherein the sensor module is arranged inside a tire; the receiver is mounted in a cab; the sensor module and the receiver are in communication connection in a wireless radio frequency manner; the air pressure sensor is connected with the receiver. According to the tire pressure monitoring system disclosed by the invention, an accurate tire pressure value can be obtained through correcting an absolute pressure value of the tire, so that the accurate monitoring of the tire pressure is realized and the driving safety is improved.

Description

technical field [0001] The invention relates to a tire pressure monitoring system in the field of automotive electronics, in particular to a tire pressure monitoring system adaptive to altitude. Background technique [0002] The tire pressure monitoring system (Tire Pressure Monitoring System, TPMS) realizes the real-time monitoring of tire pressure through the tire pressure sensing unit and tire pressure monitoring unit using radio frequency communication. TPMS is mainly composed of two parts, the first part is the sensor, which is installed inside the tire and fixed on the wheel hub through the valve, which can monitor the temperature, pressure and acceleration of the tire in real time; the second part is the receiver, which is installed in the cockpit Inside, the wireless signal sent by the sensor can be received, and the current tire pressure, temperature and fault conditions can be obtained through calculation and analysis, so that the driver can understand the conditio...
