Simulation scene management method and device

Abstract

The invention provides a simulation scene management method and device. The method decouples the automatic driving vehicle, each traffic participant and each monitoring task by setting various time baselines based on time synchronization, and each time baseline is only responsible for its own When a new simulation scene needs to be constructed, it is only necessary to determine each target time baseline that the simulation scene needs to participate in according to the management requirement parameters, and update the original management information in each target time baseline to obtain the target management information. That is, due to the low coupling between the management objects of each time baseline, the information update of each target time baseline is performed independently and will not affect other target time baselines. Therefore, the present invention can be based on the management requirement parameters and the original scene. The management file quickly and flexibly builds multiple different simulation scenarios, supports scenario generalization, and has low management cost and difficulty, high efficiency, and can meet the needs of simulation testing.

Description

technical field [0001] The present invention relates to the technical field of simulation, in particular to a simulation scene management method and device. Background technique [0002] In an automatic driving system, a simulation environment is usually built to debug or test the automatic driving algorithm. Currently, in the scene file describing the simulation scene, the simulation scene is mostly defined and managed in the form of a behavior tree. However, in this way, the behavior of the autonomous vehicle and all traffic participants in the scene, as well as various local monitoring tasks, etc. They are all mixed in the same behavior tree. The high coupling between elements makes the editing of the scene more expensive and difficult. When it is necessary to add or reduce traffic participants in the scene, change the status of traffic participants, When editing operations such as changing monitoring tasks, the editing cost is no less than rewriting a new behavior tree,...
