Simulation method for software combined automatic driving system

Abstract

The invention belongs to the field of automatic driving simulation, and discloses a software combined automatic driving system simulation method, which comprises the following steps of: generating corresponding traffic flow automobile information by utilizing Vissim according to different simulation requirements; the traffic flow automobile information is imported into a non-automatic driving vehicle of a perception and environment module; the Simulink constructs a planning and control module function according to the function requirement of the automatic driving automobile, and automatic driving is realized in the virtual scene; the automobile dynamics module realizes position posture change of the automobile according to the automobile behavior decision generated by the planning and control module; the automobile dynamics module completes the position and posture change of the automatic driving vehicle and then transmits the information back to the sensing and environment module step by step, and then the information is transmitted to the Vissim through an external interface; the visualization module displays current road and vehicle information in real time. According to the invention, virtual simulation close to a real driving scene is realized, and the accuracy and effectiveness of function testing of the automatic driving vehicle are improved.

Description

technical field [0001] The invention belongs to the technical field of automatic driving simulation and system simulation, and in particular relates to a method for simulating a software-integrated automatic driving system. Background technique [0002] With the development of sensing devices such as radars and cameras, self-driving cars have also entered an explosive period. The safety and stability verification of automatic driving systems is the key content of autonomous driving technology research and development. [0003] The simulation test is to reconstruct the scene and road information required for automatic driving through the computer simulation system to simulate the driving situation of the automatic driving vehicle. [0004] Since the simulation test does not require real vehicles to be tested on actual roads, it can reduce research and development costs and eliminate potential safety hazards, and at the same time, a large amount of training data can be obtaine...
