Abstract

The invention provides a method and a system for preventing mis-alarming of a tire pressure monitoring system. The method at least comprises the following steps of S1. monitoring an initial pressure value P0 of a tire when a vehicle is started; S2. setting a time threshold value A of the vehicle starting moment; and S3. within the time threshold value A, performing estimation compensation according to an actual monitored tire measurement pressure value P1 to obtain an estimated tire pressure value P, when the estimated tire pressure value P is smaller than the standard preset percentage of the standard tire pressure P, sending an alarm for extremely low tire pressure, and when the vehicle driving time is longer than the time threshold value A, and the actual monitored tire measurement pressure value P1 is smaller than the standard preset percentage of the standard tire pressure P, sending the alarm for extremely low tire pressure. The method and the system for preventing mis-alarming of the tire pressure monitoring system can accurately prevent the mis-alarming of the tire pressure monitoring system, and are easy to implement.

Description

technical field [0001] The invention relates to the technical field of automobile tire pressure monitoring, in particular to a method and system for preventing false alarms of a tire pressure monitoring system. Background technique [0002] Automobile is a modern means of transportation and has become an indispensable means of transportation for people's daily life. With the continuous development of the automobile industry, people pay more and more attention to safety. Tires are an important part of the driving mechanism of a car. They not only carry the entire mass of the car, but also provide propulsion for the car to move forward, and play a role in easing the impact of the ground. Therefore, a tire pressure monitoring system (Tire Pressure Monitoring System, TPMS) for real-time monitoring of tires is applied, which can remind drivers to pay attention to possible safety problems and prevent accidents in advance. Many countries and regions have adopted legal means to us...
