Description

technical field

[0001] The present application relates to the technical field of automotive electronic communication, in particular to a vehicle active RFID (Radio Frequency Identification, radio frequency identification) antenna adjustment device, controller and method. Background technique

[0002] With the development of automobile technology, the engine, gearbox, drive axle, etc. are integrated to form an automobile powertrain system. Among them, electronic tags are used to realize the information identification, monitoring and management of the powertrain system, so as to improve the parameter identification and information management of the automotive powertrain system.

[0003] In the existing technology, passive electronic tags are usually installed on cars, but passive electronic tags usually require no-coverage transmission, so the transmission distance is short, the amount of transmitted data is small, and only one-way reading is supported, so it is difficult to e...

Embodiment Construction

[0033] The following embodiments of the present invention provide a vehicle active RFID antenna adjustment device, a vehicle controller and a method.

[0034] In this embodiment of the application, an active RFID tag is used to realize the adjustment of the active RFID antenna for vehicles. The tag is usually composed of a coupling element and a chip. Each tag has a unique electronic code and is attached to the object to identify the target object. Active RFID electronic tags have the characteristics of long transmission distance and can meet the characteristics of data transmission under vehicle coverage conditions. Compared with passive RFID electronic tags, the amount of transmitted data is large, and it is not limited by the installation direction of the vehicle controller.

[0035] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, and to make the above-mentioned purposes, features and advan...
