Vehicle headlight road illumination performance testing method and device

Abstract

The present invention discloses a vehicle headlight road illumination performance testing method and device and belongs to the vehicle field. The method includes the following steps that: when the headlight of a vehicle is turned on, the illuminance values of a plurality of areas on a road surface in front of the vehicle are measured; the plurality of illuminance values are put into statistics according to at least one measurement index, so that the measured values of the headlight under the at least one measurement index are obtained; the objective measured scores of the headlight are calculated according to the obtained measured values; the evaluation scores of the headlight under at least one evaluation index are obtained, wherein the evaluation scores are determined by a tester according to the illumination effect of the headlight; the subjective scores of the headlight are calculated according to the obtained evaluation scores; and the sum of the subjective scores and objective scores is calculate and is adopted as the test result of the headlight. With the vehicle headlight road illumination performance testing method and device of the invention, design guide is provided for an operable and quantifiable test result, and the test result is adopted as a product performance inspection standard, and therefore, a development cycle can be greatly reduced, and the satisfaction of a driver with the illumination effect of the headlight can be improved.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method and device for testing road lighting performance of vehicle headlights. Background technique [0002] The headlight of the vehicle is a kind of equipment used by the vehicle for lighting. It is installed on both sides of the head of the vehicle. When the vehicle is driving at night, the headlight can be turned on to illuminate the road ahead, thereby ensuring safe driving. As the vehicle environment becomes more and more complex, the demand for the lighting effect of the headlights is getting higher and higher, and the quality of the lighting effect of the headlights directly determines the safety of driving and pedestrians. In order to ensure the normal lighting of the headlights , the headlamps need to be tested. [0003] However, for the same lighting effect of headlights, different drivers, different environments, and different road driving conditions will lead to non-unique...

Problems solved by technology

[0003] However, for the same lighting effect of headlights, different drivers, different environments, and different road driving conditions will lead to non-unique test results.

At present, no clear test plan has been proposed for the test of headlights, and no quantitative indicators have been provided to measure the illumination effect of headlights. It is urgent to propose a test plan that can quantitatively measure the illumination effect of headlights.
