A tire pressure monitoring system automatic learning method and system

Abstract

The invention provides an automatic learning method for a tire pressure monitoring system. The method comprises the following steps of 10, transmitting a frame of sensor information to a receiver at an interval of a certain period by virtue of a tire pressure sensor of each tire of a vehicle, wherein the period is set by the tire pressure monitoring system; 20, receiving the sensor information of each tire by virtue of the receiver; 30, matching each received frame of sensor information, simultaneously starting learning the sensor information which is mismatched for more than a certain number of times, the number of times being set by the tire pressure monitoring system, judging whether more than three frames of sensor information are continuously learnt or not, and if more than three frames of sensor information are continuously learnt, determining that the tire pressure sensor of the corresponding tire is learnt, and ending learning, otherwise continuing receiving the sensor information, namely returning to the step 20. The method has the advantages that the tire pressure monitoring system can learn without a learning tool, and can automatically relearn even though the tire pressure sensors are replaced, so that convenience is brought to a user, and the competitiveness of a product in the market is also improved.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an automatic learning method and system for a tire pressure monitoring system. Background technique [0002] The tire pressure monitoring system (Tire Pressure Monitoring System, TPMS) realizes real-time monitoring of tire pressure through the tire pressure sensing unit and tire pressure monitoring unit using radio frequency communication. [0003] What traditional tire pressure monitoring system adopts at present is to learn the sensor of four tires with learning tool, then can't learn under the situation that does not have learning tool, so it has following defect: 1. Loading plant loads tire pressure monitoring system 2. If you want to replace the sensor, you need to go to a specific 4S shop with learning tools to replace it. 4S shops without specific learning tools cannot learn; 3. After the tire is changed , you need to use learning tools to re-learn. [0004] Existing related t...
