drive cycles, driver models, test maneuvers, and 3d simulation in unreal engine® visualization environment

to configure vehicle scenarios, use the drive cycle, driver, and 3d simulation blocks.

  • drive cycle source block — generates a standard or user-specified longitudinal drive cycle. by default, the block includes the ftp–75 drive cycle. to install additional drive cycles from a support package, see . the support package has drive cycles that include gear shift schedules, for example jc08 and cuedc.

  • driver blocks — implement controllers that generate normalized steering, acceleration, and braking commands to track velocity or displacement.

  • 3d visualization blocks — integrate 3d visualization environment with simulink® so that you can interrogate the world around the vehicle for virtually testing perception, control, and planning algorithms.

topics

simulation basics


  • learn now to visualize vehicle performance in a 3d environment using the unreal engine from epic games®.

  • when simulating in the unreal engine environment, keep these software requirements, minimum hardware requirements, and limitations in mind.

  • learn about the co-simulation framework between simulink and the unreal engine and how block execution order affects 3d simulation.

  • understand coordinate systems for representing vehicle dynamics.

  • use the simulation 3d message set and simulation 3d message get blocks to communicate with the double-lane change scene.

  • create an oval track with roadrunner and use it in a vehicle dynamics blockset™ simulation that co-simulates with unreal®.

scene customization


  • to customize scenes and vehicles, use the vehicle dynamics blockset interface for unreal engine 4 projects support package.

    • step 1:
    • step 2:
    • step 3:
    • step 4:

  • use the simulation 3d message get and simulation 3d message set blocks to communicate with the unreal editor.

  • animate a custom bicycle actor.

  • build and use lighting in the unreal editor.

  • create empty project to use in custom scenes.

  • place the simulation 3d camera getsimulation 3d camera getsimulation 3d camera block on static and custom actors.

  • create custom vehicle mesh for the simulation 3d vehicle and simulation 3d vehicle with ground following blocks.
