AI summary

A vehicle automatic networking apparatus with a first component and a second replaceable component includes a first identity recognition module on the first component and a second identity recognition module on the second component. The second module in a networking mode transmits a low frequency wake up signal through a low frequency signal transmission circuit to wake up the first module. A first identity recognition module low frequency sensor circuit senses the low frequency wake up signal, and responds by transmitting an identity code of the first component through a low frequency signal transmission circuit. A second module low frequency signal receiving circuit receives and stores the first component identity code. In a following data transmission, the second module sends data with the identity code, and a first component receiving apparatus identifies it. The first and second modules are both located rearward of a second component connection hitch.
