Target object carrying platform car for vulnerable traffic participants

Abstract

The invention discloses a vulnerable traffic participant target object carrying platform car which comprises a chassis frame system, and a driving system, a steering system and a suspension system are installed on the chassis frame system. The driving system comprises two driving mechanisms arranged in the longitudinal direction of the chassis frame system, each driving mechanism comprises two driving assemblies arranged in the axial direction of the chassis frame system, and each driving assembly comprises a driving wheel; the steering system comprises two sets of steering assemblies arranged in the longitudinal direction of the chassis frame system, and the steering assemblies are rotationally connected with the two sets of driving assemblies in the driving mechanisms on the corresponding sides. The suspension system comprises suspension assemblies installed on the driving assemblies, and the suspension assemblies are integrally arranged in the horizontal direction. According to the scheme, the turning radius is small, and the overall height is low, so that operation of road traffic participants can be simulated more truly, the situation that the carrying platform vehicle is captured by an environment sensing system of a tested vehicle is reduced, and the accuracy of a test result is improved.

Description

technical field [0001] The invention relates to the technical field of automobile safety testing, in particular to a platform vehicle for carrying targets of vulnerable traffic participants. Background technique [0002] At present, smart cars are in a critical period of transition from laboratories to marketization. Extensive and comprehensive testing is the only way for smart cars to mature. At present, my country has promulgated a series of test regulations for the evaluation of intelligent networked vehicles, and various automobile OEMs and intelligent vehicle proving grounds have put forward an urgent demand for intelligent vehicle road test equipment. However, related testing equipment has always relied on foreign imports, which has seriously affected the development of my country's intelligent networked automobile industry. [0003] In the field test of the active safety function of smart cars, in order to accurately simulate the changing and complex movement charact...

AI Technical Summary

Problems solved by technology

[0004] Existing platform vehicles are generally used to carry fake vehicle targets, and the rear-wheel drive front-wheel steering structure is used to make the turning radius very large, which cannot realistically simulate the movement of real road traffic participants, and the overall height of the platform vehicle Higher, when there is no cover above it, it is easy to be captured by the environment perception system of the test vehicle, causing the problem that the behavior information of the traffic participants captured by the tested vehicle does not match the actual situation, which in turn affects the accuracy of the test results
