s4: if the identity identification is passed, the control module 13 sends an unlocking instruction to the BCM6, performs door unlocking operation, and executes S1;
S5: if the identity identification fails, the control module 13 sends a warning instruction to the BCM6 to send a prompt that the vehicle door is not unlocked; if the image pickup unit 11 determines that the object is far away, S1 is executed, and if the image pickup unit 11 determines that the object is not far away, S2 is executed.
Alternatively, the identification is face recognition or human eye iris recognition.
In summary, according to the intelligent B-pillar trim panel assembly and the identity recognition method for the automobile, the base with the infrared recognition module is arranged on the side, facing the B-pillar metal plate, of the ultra-white glass, so that the functionality of the automobile B-pillar trim panel assembly is improved, the composite optical film layer is attached to the side, facing the B-pillar metal plate, of the ultra-white glass, the whole B-pillar trim panel is provided with high infrared transmittance, the identity recognition of the infrared recognition module is ensured, the infrared recognition module and the base are hidden in the ultra-white glass and the B-pillar metal plate, the attractiveness is improved, the appearance of the B-pillar of the automobile is integrated, and the glass does not need to be singly left white so that the optical sensor can receive visible light signals; in the invention, the flatness of the composite optical film layer attached to the glass is better, and the processing efficiency is higher.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent changes made by the specification and drawings of the present invention, or direct or indirect application in the relevant art, are included in the scope of the present invention.
