[0002] The front view of the car ensures that the driver and passengers have a comfortable view. When the driver observes through the transparent area, the vehicle structure and parts will cause the driver's vision obstacle, which seriously affects driving safety and comfort.
[0003] GB11562-1994 Automotive Front Vision Requirements and Measurement Methods stipulates the basic requirements and measurement methods of front vision, but the requirements are only applicable to passenger cars, not to heavy-duty SUVs and MPVs.

Embodiment 1

[0017] see Figure 1 ~ Figure 4 , the driver's front visual field measurement and checking method of the present invention simulates complex road conditions under traffic conditions, uses CATIA software to model, simulates the driver's external road environment during road travel, and takes the driver's subjective Convert the driving experience into a road CAD scene for field of view calibration; project the road CAD scene on a sphere centered on the eye point, and at the same time, affect the front windshield, A-pillar, side windshield, and exterior mirrors that affect the driver's front vision and the sealing strip are projected on the sphere to simulate the imaging of the road CAD scene in the driver's eyes; according to the driver's observation habits, the front view is divided into nine visible areas, and the percentage of the driver's visible area in each area is calculated , to check and quantify the driver's forward vision.

Embodiment 2

[0019] see Figure 1 ~ Figure 4 . Factors that affect the driver's front vision include front windshield, A-pillar, side windshield, exterior rearview mirror and sealing strip. The invention uses CATIA software to carry out modeling analysis, and simulates the most complicated road conditions and simulated vehicles passing through the crossroads. Modeling of this road condition includes intersections, traffic lights that drivers need to watch, pedestrians, etc. The road surface is projected onto a spherical surface with the eye point as the center and a radius of 5 meters. At the same time, the front windshield, A-pillar, side windshield, exterior rearview mirror and sealing strip that affect the driver's forward vision are projected on the sphere. According to the driver's observation habits, the 5-meter spherical surface is divided into nine observation areas. By calculating the percentage of the driver's visible area in each area, the driver's forward vision is checked fo...

Abstract

The invention relates to a front field of view requirement and a checking method of a driver of an automobile. A method for measuringand calibrating adriver's vision ahead includes simulating the complicated road condition under traffic condition, modeling with CATIA software, simulating the driver's external road environment while driving on the road, and converting the driver's subjective driving experience into a road CAD scene with vision calibrated. The road CAD scene is projected on a sphere centered on the eye point, and the front windshield, a-pillar, cross windshield, exterior rearview mirror and sealing strip, which affect the driver's vision, are projected on the sphere to simulate the road CAD scene imaging on the driver's eyes. According to the driver's observation habit, thefront field of vision is divided into nine visual areas, and the percentage of the driver' s visual area in each area is calculated to check and quantify the driver 's front field of vision. The method is simple, accurate and suitable for passenger car, MVP, SUV, light truck and medium-heavy truck, which is helpful to realize safe driving.

Description

technical field [0001] The invention relates to the checking of the front visual field of the general layout of the automobile design, in particular to a requirement and a checking method for the front visual field of the car driver. Background technique [0002] The front view of the car ensures that the driver and passengers have a comfortable view. When the driver observes through the transparent area, the vehicle structure and parts will cause the driver's vision obstacle, which seriously affects driving safety and comfort. [0003] GB11562-1994 Automotive Front Vision Requirements and Measurement Methods stipulates the basic requirements and measurement methods of front vision, but the requirements are only applicable to passenger cars, not to heavy-duty SUVs and MPVs. At the same time, the front vision requirements are the most basic requirements. In the process of using the vehicle by the personnel, it is even more uncertain.
