Description

Method and system for controlling the opening and closing of the trunk or tailgate of a vehicle The present invention relates to a method and system for controlling the opening and closing of a vehicle's trunk or tailgate. The vehicle is equipped with a trunk for loading items, and the trunk can be used by operating a drive switch installed on the vehicle's tailgate or trunk lid. Recently, features that allow the trunk or tailgate to open and close automatically are frequently added as options to vehicles. Accordingly, the driver or user (hereinafter referred to as the driver) can easily open or close the trunk or tailgate simply by pressing a button on the drive switch equipped on the vehicle or fob key. Meanwhile, although vehicles are equipped with various sensors, such as RF sensors or ultrasonic sensors, to prevent collisions with obstacles, the technology to use these sensors to prevent collisions with obstacles during the opening or closing of the trunk or tailgate is still lacking. In particular, blind spots exist within the range of operation when opening or closing the trunk or tailgate, making it impossible to clearly detect obstacles. Consequently, when obstacles are present, damage frequently occurs as the trunk or tailgate opens or closes; in particular, injuries frequently occur when the obstacle is a person. FIG. 1 is a flowchart of a trunk/tailgate opening/closing control method according to one embodiment of the present invention. FIGS. 2a to 3d are drawings for illustrating an example of the mounting area and location of the first sensor and the second sensor. FIG. 3 is a block diagram of a trunk or tailgate opening and closing control system of a vehicle according to one embodiment of the present invention.

Hereinafter, a method for controlling the opening and closing of a trunk or tailgate (hereinafter, trunk/tailgate) of a vehicle according to an embodiment of the present invention will be described with reference to FIGS. 1 to 2d. FIG. 1 is a flowchart of a trunk/tailgate opening/closing control method according to one embodiment of the present invention. A trunk/tailgate opening/closing control method according to one embodiment of the present invention comprises: a step (S110) of determining whether a vehicle is stopped for opening/closing a trunk or tailgate (hereinafter, trunk/tailgate); a step (S120) of receiving an input of the trunk/tailgate opening/closing button; a step (S130) of detecting whether there is an obstacle within a preset unfolding range of the trunk/tailgate based on a sensor attached at a predetermined location of the vehicle; and a step (S140) of stopping the trunk/tailgate opening/closing operation when it is detected that the obstacle exists. Meanwhile, each step illustrated in FIG. 1 can be understood as being performed by the trunk/tailgate opening/closing control system (100) of FIG. 4 described later, but is not necessarily limited thereto. First, it is determined whether the vehicle is stopped in order to open or close the trunk/tailgate (S110). Then, if it is determined that the vehicle is stopped, control o
