Tail gate opening and closing control system and tail gate opening and closing control method

Abstract

The invention relates to a tail gate opening and closing control system and a tail gate opening and closing control method.The system comprises a central controller, a millimeter wave radar sensor, a projection lamp and a tail gate controller, the millimeter wave radar sensor, the projection lamp and the tail gate controller are all connected with the central controller, the projection lamp is used for illuminating a preset area, and the tail gate controller is used for controlling the projection lamp to illuminate the preset area. The central controller is set to control the projection lamp to be turned on and control the millimeter wave radar sensor to work when it is detected that the position of a vehicle key enters a tail door triggering area. The millimeter wave radar sensor is configured to send a control instruction to the central controller when detecting that an object enters a preset area and does not leave the preset area within a preset time or when detecting that a kicking action executed by the object in the preset area accords with a threshold feature of a preset point cloud model. Whether the trigger action occurs in the preset area or not is detected by indicating the preset area, so that opening or closing of the tail gate can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of automobile intelligent control, in particular to a tailgate switch control system and a tailgate switch control method.
