Abstract

The present invention relates to an automatic networking apparatus for vehicles for a vehicle with a first component and a second replaceable component, and it comprises a first identity recognition module disposed on the first component and a second identity recognition module disposed on the second component. When the second identity recognition module turns into a networking mode, it transmits a low-frequency wake-up signal through a low-frequency signal transmission circuit to wake up the first identity recognition module. A low-frequency sensor circuit of the first identity recognition module is able to sense the low-frequency wake-up signal, and responds to the low-frequency wake-up signal to transmit an identity code corresponding to the first component through the high-frequency signal transmission circuit. The high-frequency signal receiving circuit of the second identity recognition module can receive the identity code of the first component and store the received identity code. In the following data transmission, the second identity recognition module can send the data with the identity code of the first component loaded with, so that a receiving apparatus of the first component identifies it. The present invention features in networking automation, simple installation, and convenient maintenance.
