Electric tail door kicking opening control method based on image recognition

Abstract

The invention provides an electric tail door kicking opening control method based on image recognition. The method comprises the following steps of: 1, after a vehicle is locked, when a vehicle body type controller with a near vehicle unlocking function detects that a vehicle user carries a legal key or an unlocked mobile phone gradually gets close to a vehicle tail area of the vehicle, a vehicle rearview camera and the controller are waken up, and a near vehicle unlocking instruction with a tail door area triggering identifier is sent; 2, after the rearview camera and the controller at the tail of the vehicle are awakened, feedback is sent to the whole vehicle, the whole vehicle drives a backup lamp to be lightened for preset seconds, and meanwhile, the backup camera and the controller recognize whether two legs of a person facing the vehicle appear in a recognition area at the tail of the vehicle within preset milliseconds when the backup lamp is lightened; and 3, when the reversing camera and the controller recognize the kicking action facing the vehicle in the specific area, a request instruction for triggering the electric tail door to be opened is started, and the electric tail door is driven to be opened to the maximum degree.

Description

technical field [0001] The invention belongs to the technical field of automatic opening of an electric tailgate, and in particular relates to an image recognition-based control method for kicking the opening of an electric tailgate. Background technique [0002] At present, most of the tailgates of automobiles are electric tailgates. For example, the automatic opening of the tailgate is realized by the remote control key of the car or the touch of the tailgate opening switch. However, these operations require manual operation, but it is not convenient to open the tailgate when the owner is holding a heavy object and cannot release his hands. It is necessary to put the item on the ground first, and then move the heavy object into the trunk after opening the tailgate. [0003] In response to this problem, a kick sensor has been developed in the prior art. A capacitive sensing antenna is arranged on the rear bumper of the car to monitor the capacitance value of the antenna rel...

AI Technical Summary

Problems solved by technology

However, this solution has the following defects in practical application: 1) It is necessary to add an antenna and controller of about 1 meter, resulting in an increase in the cost of the vehicle; 2) The capacitive sensing antenna is generally about 1 meter, and the area that can effectively trigger unlocking is small ;3) When opening the tailgate, the kicking action is relatively high. It is necessary to quickly extend the foot under the bumper and retract it. It takes a long time for many users to master the triggering skills, resulting in poor customer experience.
