Abstract

The invention provides a simulation method and system of a vehicle road virtual scene, and the method comprises the steps: collecting lane lines, lane identifiers, traffic signals, pedestrians and traffic vehicles of an actual road through collection equipment, and forming scene information of different driving routes. And extracting scene library cases of the data stream and the video stream according to the scene information, and carrying out data processing on the scene library cases to generate scene data and vehicle dynamic data in a set data format. And establishing a driving environmentsimulation model according to the scene data to simulate road information of vehicle driving, wherein the driving environment simulation model comprises a road model, a traffic environment model anda weather model. According to the invention, the efficiency and accuracy of function testing of vehicle intelligent driving can be improved.

Description

technical field [0001] The invention relates to the technical field of automobile test simulation, in particular to a simulation method and system for a vehicle road virtual scene. Background technique [0002] In recent years, vehicles with intelligent driving functions have sprung up in the market. From joint venture vehicles to autonomous vehicles, intelligent driving functions are the focus of development. Intelligent driving has become the main competitiveness of models, and corresponding regulations are gradually being introduced. For example, the 2018 version of C-NCAP requires vehicles with active safety systems to be eligible for five-star evaluation. In addition, the market's demand for intelligent driving functions is also growing. To win customers' trust in intelligent driving to the greatest extent, "safety" is the most important factor. For safety testing, in addition to field testing and open road performance verification, virtual verification at the early st...
