'Hardware-in-loop' accelerated loading simulation test system for intelligent connected vehicles

Abstract

The invention relates to a 'hardware-in-loop' accelerated loading simulation test system for intelligent connected vehicles, relates to the technical field of intelligent vehicle automated driving and traffic simulation, and aims to quickly test intelligent vehicle planning decision devices in a more advanced, 'real' and comprehensive manner through a rich and vivid traffic scene. The simulation test system comprises a traffic simulation layer, a data transmission layer, and an intelligent vehicle layer, which jointly restrict the operation speed of the system. The traffic simulation layer is mainly used for generating a 'real' traffic scene based on traffic simulation software and simulating the perception and reaction of intelligent vehicles to the surrounding environment, and can load multiple scenes automatically and accelerate the operation of the scene. The intelligent vehicle layer contains intelligent connected vehicles developed by different organizations. The data transmission layer is used for connecting the traffic simulation software with one or more actual intelligent vehicle planning decision devices through a hardware / software interface to transmit perception information and vehicle control information between the traffic simulation layer and the intelligent vehicle layer.
