Intelligent connected vehicle in-the-loop simulation and test and verification system and method

Abstract

The invention provides an intelligent connected vehicle in-the-loop simulation and test and verification system and method. Simulation of the intelligent trolley operation scene is performed mainly byIPG CarMaker, CarSIM and other tools. The system is composed of the functions of Simulink data simulation calculation, transmission of the simulation scene parameters to the intelligent trolley for simulation of the real scene, intelligent trolley image acquisition and display and test analysis. The intelligent trolley side is mainly responsible for environmental perception and control algorithmverification of the intelligent connected vehicle and is composed of a trolley and a control module, a driving module, a communication module and a sensor module to act as the carrier of loading the test algorithm software and the sensor and the communication module required to be tested. According to the system, the cost and the dangerousness of the intelligent connected vehicle test can be reduced, onsite verification of the intelligent vehicle system can be performed in the real site, the research work of modeling, simulation and control and other aspects for vehicle-road coordination and other application in different simulation traffic scenes and thus a lot of data support can be provided for the research of the intelligent connected vehicle.

Description

technical field [0001] The invention belongs to the technical field of intelligent networked vehicles, in particular to an in-the-loop simulation test system for intelligent networked vehicles. Background technique [0002] With the development of today's intelligent networked vehicles, in view of the complexity of actual intelligent vehicles, most of the research is only to simulate and verify the algorithms through related software. Since it is difficult to fully consider the actual vehicle communication, mechanical properties and other factors, these algorithms are in There are many problems when applied to actual intelligent vehicles. [0003] From the current point of view, the safety of intelligent driving is still questioned by the public. Tesla has had several major casualties caused by intelligent driving at home and abroad. More and more attention has been paid to the test and evaluation of smart cars, and various research institutions and universities in various ...
