Abstract: Implementations of the present specification provide a vehicle identification method and apparatus, a primary device, and a secondary device. In the vehicle identification method, after sending a low-frequency signal, the primary device receives a response signal sent by the secondary device for the low-frequency signal, and communicates with the secondary device to obtain identity information of a vehicle on which the secondary device is located, so that the vehicle can be identified. The response signal is sent from the secondary device after the secondary device receives the low-frequency signal and detects that the signal strength of the low-frequency signal is greater than or equal to a predetermined threshold, and the signal strength of the low-frequency signal rapidly attenuates as the distance increases, so that the primary device can determine the location of the vehicle on which the secondary device is located solely based on the received response signal.
