METHOD AND SYSTEM FOR MONITORING PRESSURE OF TIRE

摘要

Disclosed are a method and a system for monitoring the pressure of a tire. The system measures frequencies of multiple tires mounted on the vehicle, sets a first average frequency for a normal pressure state and a second average frequency for determination of a low pressure state, wherein the first average frequency is calculated by accumulating the measured frequencies for each speed interval in a stop mode and the second average frequency is calculated by accumulating the measured frequencies for each speed interval in a driving mode, calculates low-pressure probabilities for each speed interval of the tire by using the second frequency, a predetermined low-pressure reference frequency, and a predetermined frequency determination interval for determining low-pressure, and determines whether each tire is at low pressure state by aggregating the low-pressure probabilities for each speed interval of the tire.

1. A system for monitoring a pressure of a tire, the system comprising:
a frequency measurement unit configured to measure frequencies of multiple tires mounted on a vehicle; a frequency analysis unit configured to calculate a first average frequency in a stop mode and to calculate a second average frequency in a driving mode; a calculation unit configured to calculate a low-pressure probability for a speed interval of the tire; and a determination unit configured to determine whether the tire is at low pressure state based at least in part on the low-pressure probability for the speed interval of the tire calculated by the calculation unit.
