Title:
METHOD FOR CONSTRUCTING SIMULATION TRAFFIC FLOW AND SIMULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/041717
Kind Code:
A1
Abstract:
A method for constructing a simulation traffic flow and a simulation device for application in the field of autonomous driving simulation testing, the method comprising: for different simulation testing objectives, first implementing forward construction of a traffic scenario library that meets testing requirements, the number of each type of traffic scenario file in the traffic scenario library and the proportion of traffic scenario files belonging to different traffic scenario types being customisable, having high flexibility and, compared to the collection of real traffic flow data, not requiring labelling, being low cost and easy to acquire, having comprehensive considerations, not being limited by the collected data, and being capable of ensuring testing completeness; next, a simulation device sequentially reads traffic scenario files from the traffic scenario library, and controls a simulation vehicle to transition from the initial state of the previous scenario to the end state of the current scenario, thereby implementing continuous assignment of different simulation scenarios, such that the generated simulation traffic flow can cover the testing part of continuous switching of different scenarios; and finally, for each simulation scenario, generating corresponding test results in real time, being highly efficient.
