Unreal Engine Scenario Simulation

Develop, test, and visualize the performance of driving algorithms in a simulated environment using the Unreal Engine® from Epic Games®

Automated Driving Toolbox™ provides a cosimulation framework for modeling and visualizing driving algorithms in Simulink® in a rich simulation environment. This simulation environment uses the Unreal Engine by Epic Games.

With this simulation environment, you can configure prebuilt scenes, place and move vehicles within the scene, and set up and simulate camera, radar, or lidar sensors on the vehicles. Use this environment to develop, test, and verify the performance of perception, path planning, and control algorithms, including closed-loop algorithms. To learn more, see Unreal Engine Simulation for Automated Driving.

For a tutorial video series on connecting a Simulink vehicle to an Unreal Engine scene, see Using Unreal Engine with Simulink.
