Embodiment Construction

[0028] combine figure 1 and figure 2 , and the two figures respectively show the rear view range required by GB15084 for M1 and N1 type vehicles and EU ECER46 for III type vehicle exterior mirrors (that is, the shaded range in the figure). It can be seen that the regulations of different countries and regions have different requirements for the rear vision range of different models. In the following exemplary description, embodiments of the present invention will be described in accordance with figure 2 According to the European Union standard, the rear view check of the exterior rearview mirror is carried out, but those of ordinary skill in the art can understand that the rear view check method in the present invention is also applicable to other countries and regions, which require rear view checks for other vehicle models. .

[0029] First, establish a standard calibration module structure tree in CATIA software, which includes vehicle environment parameter set, regula...

Abstract

The invention proposes a car back-view check method based on a CATIA (computer-graphics aided three-dimensional interactive application). The car back-view check method comprises the following steps of: constructing a standard check module structure tree; constructing a car environment model; generating view ranges of regulatory requirements; constructing an obstacle model; projecting the obstacle model on a mirror surface of the car environment model, and adjusting a mirror surface drive parameter until the back-view check result meets the regulatory requirements. According to the car back-view check method, car back-view check efficiency under different regulatory requirements is improved.

Description

technical field [0001] The invention relates to the field of automobile design, in particular to a method for checking rear vision of an automobile. Background technique [0002] The safe driving of a car has an important relationship with whether the information obtained by the driver is correct or not, and the number and speed of the information acquisition devices. When a car is driving, 80% of the information is obtained by vision. Ensuring that the driver has a good vision is a necessary condition for preventing car accidents. The rear view obtained by the driver in the rearview mirror occupies a very important position in car safety, and various countries and regions have formulated corresponding regulations or standards to ensure a good rear view of the car. However, for automobile manufacturers, especially when exporting automobiles, in order to meet different laws and regulations of various countries and regions, different types of automobile rear vision must be ch...
