Specify Virtual Vehicle Test Plan

Before you build your virtual vehicle, you need to assemble your test plan. Go to the Configure section, click Scenario and Test, and select the test scenarios in this pane.

You can select two main types of test scenarios: drive cycles and vehicle performance and handling maneuvers. The available scenarios depend on the Vehicle class and Vehicle dynamics settings you chose.

You can choose the Driver setting individually for each test scenario.

Test Scenarios

For a Passenger vehicle, if you set Vehicle dynamics to Longitudinal dynamics, you can select:

  • Standard drive cycles from industry agencies and institutions. The default selection is the FTP75 drive cycle. Certain drive cycles, such as JC08 and CUEDC, prescribe gear shift schedules.

  • A Wide Open Throttle (WOT) maneuver, setting parameters such as nominal reference speed and simulation time.

Test plan pane

For a Passenger vehicle, if you set Vehicle dynamics to Combined longitudinal and lateral dynamics, you can select maneuvers for vehicle handling and stability or straight-line performance, and drive cycles. The configured virtual vehicle model implements the block that corresponds to the maneuver that you select.

Drive Cycle Source

For a Motorcycle, if you set Vehicle dynamics to In-plane dynamics, you can select:

  • Standard drive cycles from industry agencies and institutions. The default selection is the FTP75 drive cycle. Certain drive cycles, such as JC08 and CUEDC, prescribe gear shift schedules.

  • A Wide Open Throttle (WOT) maneuver, setting parameters such as nominal reference speed and simulation time.

For a Motorcycle, if you set Vehicle dynamics to Out-of-plane dynamics, you can select maneuvers for vehicle handling and stability:

  • Steady Turning

  • Handle Hit

If you want to run your virtual vehicle in the Unreal Engine® 3D simulation environment, set 3D Scene Selection to 3D Scene. For hardware requirements, see Unreal Engine Simulation Environment Requirements and Limitations (Vehicle Dynamics Blockset).

Driver Model — Passenger Vehicle

For a Passenger vehicle, you have several options for Driver model, depending on your Vehicle dynamics selection. The configured virtual vehicle model implements the block that corresponds to the driver that you select.

DriverBlock
Longitudinal DriverLongitudinal Driver (Vehicle Dynamics Blockset)
Predictive DriverPredictive Driver (Vehicle Dynamics Blockset)
Predictive Stanley DriverPredictive Driver (Vehicle Dynamics Blockset)

The parameters you set here reflect the driver technique and reaction time, and the assumptions the driver makes about the vehicle while controlling it.

Driver Model — Motorcycle

If Vehicle dynamics is set to In-plane dynamics, then Driver is set to Longitudinal Rider. If Vehicle dynamics set to Out-of-plane dynamics, then Driver is set to Open Loop.
