Abstract

The invention relates to a tire pressure monitoring system capable of locating tire pressure transmitters respectively arranged on each tire of an automobile. The tire pressure monitoring system comprises a plurality of tire pressure transmitters respectively arranged on each tire of an automobile and a receiver machine. Each tire pressure transmitter includes: an acceleration sensor, which is used to collect the acceleration of the corresponding tire and obtain an acceleration signal; a first processor, which generates an acceleration curve according to the acceleration signal and determines the frequency of the acceleration signal; and a radio frequency transmitting module, which sends the acceleration signal Frequency of. The receiver includes: a radio frequency receiving module, which receives the frequency of each acceleration signal sent by each tire pressure transmitter; a communication module, which receives the steering signal of the car; and a second processor, which connects the radio frequency receiving module and the communication module, the first The second processor determines the tire position where each acceleration sensor is located according to the frequency relationship of each acceleration signal during the steering period indicated by the steering signal.

Description

technical field [0001] The invention relates to automotive electronic equipment, in particular to a tire pressure monitoring system and a tire pressure transmitter positioning method thereof. Background technique [0002] Pressure is the most critical parameter of tires, too high or too low tire pressure will increase fuel consumption per kilometer and reduce tire life. The data shows that tire pressure is 25% lower than normal, tire life is reduced by 60%, and fuel consumption increases by 3%. In addition, the size of the tire pressure directly affects the safety of the car. Therefore, it is very necessary to install electronic sensing products on tires for real-time monitoring of tire pressure. Tire Pressure Monitoring System (TPMS) is a kind of automotive electronic equipment proposed for this purpose. [0003] A TPMS system generally includes a tire pressure transmitter installed in each tire of a car and a receiver installed in the body of the car. When a car has ti...
