The invention provides a multifunctional simulation system for automatic driving. The multifunctional simulation system comprises a virtual vehicle module, a virtual chassis control module, a virtualroad module, a virtual traffic module, a time control unit module and a visualized interactive interface module, the virtual road module provides cartographic information for an automatic driving algorithm and the virtual traffic module, the virtual traffic module provides road conditions including vehicles, pedestrian, traffic lights and the like for the automatic driving algorithm, the automaticdriving algorithm communicates with the virtual vehicle module through a virtual chassis so as to obtain vehicle information and send vehicle control instructions, a visualized interactive interfacesends human-computer interaction information to the simulation system and displays system information in a visualized three-dimensional effect, and finally, the time control unit module controls intervals of simulation time of the simulation system comprising the automatic driving algorithm. Data interfaces of the virtual modules are kept consistent with those of a real system, so that multifunctional modes, including hardware-in-loop simulation, of the simulation system can be realized.

Description

technical field [0001] The invention relates to a simulation synthesis platform for automatic driving of automobiles, in particular to a multifunctional simulation system for automatic driving. Background technique [0002] Autonomous driving is a highly complex system engineering. It is not only costly but also very dangerous to directly use immature autonomous vehicles to verify systems and algorithms on real roads. If system simulation technology can be used to test and verify self-driving vehicles in a virtual environment, the cost of manpower and material resources can be reduced, and potential safety risks can be avoided. However, there is currently no platform for rapid simulation of the entire system of autonomous driving on the market. At present, relevant simulation software often focuses on certain aspects related to autonomous driving. For example, Carsim mainly simulates the dynamics and mechanical characteristics of vehicles and parts. If necessary, it include...
