Tire pressure sensor identification method and related apparatus and system
View Patent ↗The present invention discloses a tire pressure sensor identification method, a related apparatus and system. A tire pressure sensor identification apparatus in the present invention includes a storage module configured to store identity information of a tire pressure sensor, a communications module configured to communicate with an electronic control unit (ECU) of a vehicle, a processing module and a radio frequency transmission module configured to output identity information. The tire pressure sensor identification apparatus may output the stored identity information to a corresponding vehicle, so that the vehicle can still identify the tire pressure sensor even if the tire pressure sensor is not in an activated state. It is convenient for a user to perform a uniform identification operation after uniformly collecting the identity information, thereby improving identification efficiency of the tire pressure sensor.
