US 2019/0337340 A1 · TIRE PRESSURE SENSOR IDENTIFICATION METHOD AND RELATED APPARATUS AND SYSTEM

Abstract

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. A tire pressure sensor identification system and a corresponding tire pressure sensor identification method adopting the tire pressure sensor identification apparatus also have a same technical effect.

Dependent claims

A tire pressure sensor identification apparatus, comprising a storage module, a communications module, a processing module and a radio frequency transmission module, wherein the storage module, the communications module and the radio frequency transmission module are respectively communicably connected to the processing module;

the storage module is configured to store identity information of a tire pressure sensor;
the communications module is configured to communicate with an electronic control unit (ECU) of a vehicle and to receive response information fed back by the ECU;
and
the processing module is configured to parse the response information received by the communications module to determine whether the ECU enables a sensor learning mode, and if yes, control the radio frequency transmission module to send identity information of a tire pressure sensor corresponding to the vehicle.
