Vehicle Scenarios

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 Support Package for Maneuver and Drive Cycle Data. 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.
