Method for improving passenger car tire pressure monitoring system

摘要

The present invention relates to a method for improving a passenger car tire pressure monitoring system (TPMS) including a direct TPMS and an indirect TPMS. Direct TPMS monitors the tire pressure in real time using a dynamic tire pressure reference as a basis for tire pressure determination. That is, when the tire load fluctuates, the TPMS data processing center determines and alerts the real-time tire pressure data using the cold tire pressure data corresponding to the real-time load as the current tire pressure reference. Indirect TPMS establishes a wheel speed reference database based on GPS vehicle speed standards, and compensates and corrects for wheel speed distortion due to wear of tires. Real-time wheel speed and wheel speed standards after compensation and correction Analyzes and compares the data in the database to present and alert real-time tire pressure information.
