Method and device for optimizing profile of windscreen of motor vehicle

Abstract

The invention discloses a method and device for optimizing a molded surface of automobile windshield glass, and belongs to the technical field of automobile part design. The method comprises the following steps: acquiring a to-be-optimized automobile windshield profile, and determining a first type of reference points and a second type of reference points; performing curved surface fitting on the first type of reference points and the second type of reference points to obtain a first curved surface function; calculating a coordinate difference value and a curvature difference value, and determining a first optimization reference value corresponding to the first curved surface function based on the coordinate difference value and the curvature difference value; setting a benchmark optimization reference value and a benchmark coefficient set; and adjusting a reference step length for one coefficient in the reference coefficient set, determining a second curved surface function and a second optimization reference value corresponding to the second curved surface function, and optimizing the curved surface function based on the second optimization reference value and the reference optimization reference value. By the adoption of the scheme, it can be guaranteed that the curvature of the HUD imaging area on the automobile windshield profile is within the preset curvature range, and therefore the HUD imaging effect is guaranteed.

Description

technical field [0001] The present application relates to the technical field of automotive parts design, and in particular, to a method and device for optimizing the profile of an automotive windshield. Background technique [0002] With the development of navigation technology and intelligent driving technology, in order to allow drivers to see driving information (such as vehicle speed, navigation, distance, etc.) ) technology came into being. [0003] HUD technology is to project driving information onto the windshield glass profile (the side of the windshield glass facing the driver). within the curvature range. [0004] At present, when optimizing the profile of automotive windshield glass, it is necessary to consider the boundary requirements that need to be met when the windshield glass and the automotive sheet metal are assembled, and the curvature requirements that the HUD imaging area needs to meet. However, there is no design method that considers these two de...
