AI Technical Summary

Technical Problem

Existing electric tailgates have a high rate of false triggering, their stability is affected by the environment, their manufacturing costs and failure rates are high, and their user convenience is insufficient.

Method used

By concealing an ultra-short-range infrared array in the center of the tailgate outer panel, the infrared sensing module determines when an object enters the sensing area. Combined with the vehicle status and key validity, a tailgate opening request signal is generated and forwarded to the electric tailgate system through the central gateway to control the tailgate opening.

Benefits of technology

It enables users to open the smart tailgate by simply waving their hand, improving convenience and stability, reducing the failure rate, and enhancing the user experience.

Abstract

The application relates to an intelligent tail door opening method and device, wherein the method comprises the following steps: judging whether a preset tail door sensing module in a current vehicle meets preset effective sensing requirements; in response to meeting the preset effective sensing requirements, generating a corresponding tail door opening request signal and sending the tail door opening request signal to a central gateway of the current vehicle; and forwarding the tail door opening request signal to a preset electric rear tail door system through the central gateway; judging whether the current vehicle is in a P gear state and whether a vehicle body key meets preset legal requirements and position requirements according to the tail door opening request signal by using the electric rear tail door system; and in the case that the current vehicle is in the P gear state and the vehicle body key meets the preset legal requirements and position requirements, controlling the current vehicle to perform a preset tail door opening operation. Therefore, the problems that the use convenience and stability of an existing electric tail door are poor, the manufacturing cost and potential failure rate are high, and the use experience of a user is greatly affected are solved.
