Electric closing anti-pinch control method for automobile back door

Abstract

The invention discloses an electric closing anti-pinch control method for an automobile back door. The electric closing anti-pinch control method comprises the following steps: under initially-set anti-pinch force, the automobile back door is electrically closed and enters an approach semi-lock anti-pinch area, and the anti-pinch force is increased after anti-pinch is triggered until the back dooris closed; the number of times of increasing the anti-pinch force does not exceed two, and if the anti-pinch force is increased twice, anti-pinch is triggered, and the back door is closed manually; the approach semi-lock anti-pinch area is an area between a variable force position and a semi-lock position; and the variable force position is the position where the back door starts to make contactwith an automobile body side counter-force part. The anti-pinch force is increased by several times in the approach semi-lock anti-pinch area, so that the problem that the back door cannot be electrically closed due to accidental change of the side counter force of the automobile body is solved on the technical basis of ensuring the normal anti-pinch function of the automobile back door.

Description

technical field [0001] The invention belongs to the technical field of electric safety control of an automobile tailgate, and in particular relates to an electric closing and anti-pinch control method of an automobile tailgate. Background technique [0002] During the closing process of the electric tailgate, in order to avoid pinching people, it is necessary to set an anti-pinching force value in advance to ensure that the closing force when the tailgate is closed is not greater than the anti-pinching force, thereby ensuring that people will not be pinched. [0003] However, it is precisely because of the setting of the anti-pinch force that when special reaction force fluctuations occur on the reaction parts such as the body side sealing strip, the anti-pinch false touch phenomenon is prone to occur, that is, the body side reaction force becomes too large, When the tailgate is closed, it encounters too much resistance, resulting in a non-clamping anti-pinch reversal, which...

Problems solved by technology

[0006] Aiming at the defects in the above-mentioned prior art, the present invention discloses an anti-pinch control method for electric closing of the tailgate of a car. By increasing the anti-pinch force in stages in the anti-pinch area near the half-lock, it can ensure the normal anti-pinch of the tailgate of the car. In terms of the clip function technology, it avoids the problem that the tailgate cannot be closed electrically due to the accidental change of the side reaction force of the vehicle body.
