Driver's forward field of view measurement system and method

Abstract

The present invention provides a driver' front vision measurement system. The driver' front vision measurement system comprises a receiving device, a simulation device and a central controller; the receiving device comprises a light receiving screen and a ground measuring platform, wherein the light receiving screen is used for converting received light signals into electrical signals, and the ground measuring platform is used for measuring the coordinates of a tested vehicle in a natural coordinate system and the angle value of the Z plane of a simulated state coordinate system and the ground; the simulation device comprises a laser emitter, a three-direction guide rail and a motor arranged at the terminal of the three-direction guide rail; and the central controller is used for controlling the receiving device and the simulation device, receiving a scanning result and carrying out calculation and output. According to the driver' front vision measurement system of the invention, based on the conversion of the position coordinates of a V2 point, the ratio of the projection of the V2 point in an s region to the area of the s region is calculated, so that whether any vehicle conforms the national standards can be accurately and quickly judged.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a driver's front field of view measurement system and a driver's front field of view measurement method. Background technique [0002] Since my country's accession to the WTO, many well-known international car companies have successively invested and built factories in my country. They have brought brand new car products and advanced car safety concepts. Introduced numerous test methods for automobile safety, etc. At the same time, various domestic automobile companies have also increased investment in research and development in the field of automobile safety. Several automobile safety testing laboratories have been built or are under construction, and a large number of automobile safety testing laboratories have been conducted. It has initially accumulated some design and test experience, but there is still a big gap compared with the advanced test methods of foreign...
