Abstract

The invention relates to the technical field of automatic driving simulation verification, in particular to an automatic driving joint simulation method based on multiple platforms. The invention provides an automatic driving joint simulation method based on multiple platforms. The automatic driving joint simulation method comprises the following steps: S1, acquiring automatic driving virtual scene data; S2, setting a reference track, and acquiring obstacle pose information in combination with the automatic driving virtual scene data; S3, performing calculation according to a decision planningcontrol algorithm of the vehicle to obtain a control signal, performing simulation control on each module of the vehicle according to the control signal and the vehicle body pose information, and calculating the speed and position of the vehicle; S4, obtaining the dynamic response quantity of the vehicle based on the vehicle dynamic model, and calculating and updating the vehicle body pose information in real time; and S5, outputting traffic flow pose information. Multiple professional simulation software is adopted for interactive simulation, a more accurate simulation effect is achieved, the time of getting-on joint debugging is shortened, the test range is wide, and the development process is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of automatic driving simulation verification, and more specifically, relates to a multi-platform-based automatic driving co-simulation method.
