That is, in this embodiment, by receiving a control instruction sent by the mobile terminal for a specified function, after verifying that the control instruction is valid, the vehicle control host module sends a preset level signal to a control pin of the auxiliary factory key module according to the control instruction, and the control pin controls two function pins corresponding to the specified function to be communicated according to the preset level signal, so that a control signal for executing the specified function is sent to the vehicle, thereby realizing intelligent control of the vehicle and improving user experience.
