Power assembly of traffic simulator bearing platform for unmanned test

Abstract

The invention discloses a power assembly of a traffic simulator bearing platform for an unmanned test. The power assembly comprises a bearing platform power assembly and an executing mechanism installed on the bearing platform power assembly. The bearing platform power assembly is controlled to operate through a power control system; the bearing platform power assembly is composed of an assembly shell, two groups of driving motors, a speed reducing device and a braking device. The power output ends of the two groups of driving motors are connected with driving gears; the two sets of driving gears are symmetrically arranged in the assembly shell, the speed reducing device comprises an output gear movably installed between the two sets of driving gears and a coupler perpendicularly installedin the middle of the output gear, and the output gear is movably installed in the middle of the assembly shell and connected with the driving gears on the two sides in a meshed mode. The bearing platform power assembly designed by the invention can be matched with other mechanisms and can be mounted, so that various traffic participants such as simulated automobiles, simulated motorcycles, simulated bicycles, simulated pedestrians and the like are realized.

Description

technical field [0001] The invention relates to the field of intelligent vehicle ADAS simulation technology, in particular to a power assembly of a traffic simulation body carrying platform used for unmanned driving tests. Background technique [0002] The research and development of smart car ADAS belongs to the strategic development direction of each car company. With the implementation of various supporting technologies, laws and regulations, the mass production of smart cars with ADAS functions (hereinafter referred to as smart cars) is just around the corner, and will gradually enter people's daily lives, and finally achieve high safety without manual intervention. intelligent transportation. [0003] In the research and development stage of smart cars, the relevant tests and experiments are basically realized through closed field simulation tests and large-scale integrated devices of traffic and road simulation systems. A large amount of test data is obtained through...

AI Technical Summary

Problems solved by technology

[0005] However, the following problems exist in the existing intelligent vehicle ADAS traffic simulation process: (1) lack of a power mechanism for the operation of vehicles, bicycles, personnel and other vehicles in the traffic simulation, it is convenient to carry out dynamic (2) The existing simulation methods are relatively simple and cannot fully simulate the traffic, which leads to the lack of accuracy of the test results
