Embodiment 2

[0072] Example 2, referring Figure 4 As shown, the present embodiment is similar to the method of Example 1, the difference is that the following steps are included: S4: When the ECU controls the car tailgate open, the car tailgate rotates every time θ3 angle, the smaller the setpoint, the better, the accuracy of the detection can be improved, the present embodiment of the embodiment of the θ3 is set to 5 °, the distance between the car tailgate and the rear end obstacle is detected once L11, the ECU compares the size of L1 and L11, when L11 is less than L1, recalculate the angle at which the car tailgate can be opened is θ4, The calculation method is the same as the method used to calculate θ1 above, and the ECU controls the support device to open the car tailgate at an angle of θ4.

[0073] at Figure 4In the car tailgate rear of the obstacle may be due to the shape of the obstacle is irregular, only by detecting the distance between the car tailgate and the obstacle is not accur...

Embodiment 3

[0074] Example 3, referring to Figures 5 through 7 As shown, the present embodiment and the method of Example 1 are substantially similar, the difference is that, the support device is a support rod 1, the support rod 1 belongs to the prior art, and can be controlled by the ECU for telescopic, one end of the support rod 1 is connected to the car tailgate 3, the other end is connected to the car body, the feature is that the support rod 1 includes a guide sleeve 11 and a piston rod 12, one end of the piston rod 12 can slide the setting within the guide sleeve 11, the other end of the piston rod 12 is connected to the car tailgate 3, The end of the piston rod 12 is connected to the tailgate 3 of the car with a retract mechanism 2.

[0075] Retract mechanism 2 includes:

[0076] Fixed segment 21, fixed segment 21 fixed set at the end of the piston rod 12, fixed segment 21 is provided with a first inclined segment 211, the first inclined segment 211 is provided in the circumferential ...

Abstract

The invention discloses an anti-collision control method for an electric tail door of an automobile, and aims to overcome the defects that in the prior art, whether the rear part of a tail door has an obstacle or not is detected and judged, so that whether the tail door can be opened or not is judged, and a method for judging the opening angle is complex. The technical problem is solved through the following steps that firstly, a distance measuring device detects the distance L1 between a tail door and an obstacle at the rear end, and the opening angle theta 1 of the automobile tail door is calculated; secondly, the distance measuring device detects the distance L2 between the tail door and an obstacle at the upper end, and the opening angle theta 2 of the automobile tail door is calculated; finally, the set safety distance is compared with the LI, and if L1 is large, the opening angle of the automobile tail door is theta2; if L1 is small, theta 1 and theta 2 are compared, and the smaller value serves as an output value. The method for opening the tail door is simple, and meanwhile, the opening angle of the automobile tail door can be accurately controlled.

Description

Technical field [0001] The present invention relates to the field of automotive technology, more particularly, it relates to an automotive electric tailgate anti-collision control method. Background [0002] With the development of the automotive industry, automobiles are gradually developing in the direction of electrification and intelligence. As a new type of tailgate opening method, electric tailgate has begun to gradually replace the manual opening method because of its convenience, and it is more and more widely used in the models of various car companies. [0003] At present, the electric tailgate generally contains a height setting function, and the opening height of the tailgate can be set manually by pressing the tailgate button or set by the central control screen. However, in special cases, such as when the ceiling is low, when the tailgate is opened, manual identification is required, and after opening to a certain extent, the tailgate is suspended. At this time, the...
