Automobile minimum turning diameter measuring system based on LD ranging and method

Abstract

The invention relates to the vehicle detection technology, in particular to an automobile minimum turning diameter measuring system based on LD ranging and a method. The measuring method comprises anautomobile to be detected, an LD range finder, an LD reflecting device and a telescopic bracket. The bottom of the LD range finder is fixed on the telescopic bracket and the LD reflecting device as high as the LD range finder is located on a longitudinal axis of the automobile to be detected. The measuring system solves the problem that a measuring device needs to be installed again in case of left-turning and right-turning measurement of an automobile in the prior art, adopts the the most proven LD ranging technology and the wireless data transmission technology with the advanced measurementtechnology, achieves the integration of the measurement system and has simple structure, high measurement accuracy, low requirements for measuring environmental conditions and high repeatability, reduces the loss of manpower, material and financial resources during measurement; and improves the problems in traditional measurement methods such as complicated structure of devices, higher requirements for measurement environment conditions and lower precision, complicated measurement process and lower repeatability.

Description

technical field [0001] The invention belongs to the technical field of vehicle detection, in particular to a system and method for measuring the minimum turning diameter of a vehicle based on LD ranging. Background technique [0002] The minimum turning diameter of a car refers to the diameter of the track circle left by the center plane of the outer steering wheel on the support plane when the steering wheel of the car is turned to the limit position, and the car travels at the lowest forward gear and at a lower speed for one round. The minimum turning diameter of a car is an important index to measure the quality and maneuverability of a car. It largely characterizes the ability of a car to pass through narrow curved areas or bypass insurmountable obstacles. The smaller the value, the better the car's maneuverability. With the rapid development of the economy, the production and ownership of automobiles are increasing year by year, and the requirements for automobile quali...

AI Technical Summary

Problems solved by technology

After the car is off the assembly line, the minimum turning diameter of the car must be measured, and the existing test method has the problem of reinstalling the measuring device when the vehicle turns left and right; the loss of manpower, material and financial resources is large; the structure of the device Complexity, high requirements for measurement environment conditions and low precision; and complicated measurement process and low repeatability
