Vehicle identification method and apparatus, primary device, and secondary device

A vehicle identification method, comprising:

• sending, by a primary device located on a vehicle, a low-frequency signal with a determined radiation range;
• receiving a response signal sent by a secondary device responding to the low-frequency signal, the response signal being sent by the secondary device in response to the secondary device receiving the low-frequency signal and detecting that signal strength of the low-frequency signal is greater than or equal to a determined threshold;
• and
• communicating with the secondary device to cause the secondary device to obtain identity information of the vehicle on which the primary device is located.

An electronic device, comprising:

• one or more processors;
• and
• one or more memories communicatively coupled to the processor, the one or more memories storing executable instructions, which when executed by the one or more processors enable the one or more processors to implement acts including:
• sending, by a primary device, a low-frequency signal with a determined radiation range;
• receiving a response signal sent by a secondary device located on a vehicle responding to the low-frequency signal, the response signal being sent by the secondary device in response to the secondary device receiving the low-frequency signal and detecting that signal strength of the low-frequency signal is greater than or equal to a determined threshold;
• and
• communicating with the secondary device to obtain identity information of the vehicle on which the secondary device is located.
