SOFTWARE COMBINATION-BASED AUTOMATIC DRIVING SYSTEM SIMULATION METHOD

WIPO Patent Application WO/2023/103205

A1

The present invention relates to the field of automatic driving simulation. Disclosed is a software combination-based automatic driving system simulation method, comprising the following steps: according to different simulation requirements, using Vissim to generate corresponding traffic flow vehicle information; importing the traffic flow vehicle information into a non-automatic driving vehicle in a sensor and environment module; Simulink constructing functions of a planning and control module according to the functional requirements of an automatic driving vehicle to achieve automatic driving in a virtual scene; a vehicle dynamics module achieving position and attitude change of the vehicle according to a vehicle behavior decision generated by the planning and control module; after the vehicle dynamics module completes the position and attitude change of the automatic driving vehicle, feeding back information to the sensor and environment module step by step, and then transmitting the information to Vissim by means of an external interface; a visualization module displaying current road and vehicle information in real time. The present invention achieves virtual simulation close to a real driving scene, thereby improving the accuracy and validity of automatic driving vehicle function test.
