Automatic tail gate device of vehicle

Abstract

The invention provides an automatic tail gate device of a vehicle. The automatic tail gate device comprises a tail gate, a ranging sensor, a controller and an actuator driving the tail gate to move. The controller starts the ranging sensor to work after receiving a tail gate opening instruction, or automatically opens the tail gate by controlling the actuator after receiving the tail gate opening instruction. The ranging sensor is mounted on the tail gate and arranged horizontally to emit ranging signals to the rear portion of the vehicle and calculate the horizontal distance between the ranging sensor and a barrier behind the vehicle. When the horizontal distance between the ranging sensor and the barrier behind the vehicle is smaller than or equal to the horizontal distance between the ranging sensor and the outermost edge of the tail gate when the opening length of the tail gate is maximized in the horizontal direction, the controller controls the tail gate not to open; otherwise, the controller controls the tail gate to open.

Description

Technical field [0001] The invention relates to an automatic tailgate device for vehicles, in particular to an automatic tailgate device for vehicles with anti-collision function. Background technique [0002] In the prior art, during the opening process of the tailgate (including the trunk lid) of the vehicle, it is likely to happen when the electric switch is directly pressed to open the tailgate due to the small space behind the vehicle or the small top space of the vehicle. A collision with an obstacle behind or with an obstacle above the vehicle causes damage to the vehicle. Especially for some medium and large vehicles such as medium SUVs, large SUVs or crossovers, during the process of automatically opening the tailgate, it is easy to cause the tailgate to collide with obstacles due to the narrow parking lot or parking space. [0003] Although the automatic tailgate of a vehicle in the prior art is opened, the tailgate can stop after encountering an obstacle, but because th...

[0002] In the prior art, during the opening process of the tailgate (including the tailgate) of the vehicle, it is easy to happen when the electric switch is directly pressed to open the tailgate due to the small space behind the vehicle or the small space on the top of the vehicle. Colliding with an obstacle at the rear or colliding with an obstacle above the vehicle, causing damage to the vehicle

Especially for medium and large vehicles such as medium-sized SUVs, large SUVs or crossovers, when the tailgate is automatically opened, it is easy for the tailgate to collide with obstacles due to the small parking lot or parking space.

[0003] Although the automatic tailgate of the vehicle in the prior art will stop immediately after hitting an obstacle during the opening process, the paint or other vulnerable parts on the tailgate have rubbed against the obstacle. collision, causing damage, affecting the appearance of the vehicle or the realization of some functions
