Description
Note
Simulating models with the Simulation 3D Three-Wheeled Vehicle block requires Simulink® 3D Animation™.
The Simulation 3D Three-Wheeled Vehicle block implements a vehicle with three wheels in the 3D simulation environment.
To use this block, ensure that the Simulation 3D Scene Configuration
block is in your model. If you set the Sample time parameter of
this block to -1
, the block uses the sample time specified in the
Simulation 3D Scene Configuration block.
The block input uses the vehicle Z-down right-handed (RH) Cartesian coordinate system defined in SAE J6701. The coordinate system is inertial and initially aligned with the vehicle geometric center:
X-axis — Along vehicle longitudinal axis, points forward
Y-axis — Along vehicle lateral axis, points to the right
Z-axis — Points downward
Tip
Verify that the Simulation 3D Three-Wheeled Vehicle block executes before the Simulation 3D Scene Configuration block. That way, Simulation 3D Three-Wheeled Vehicle prepares the signal data before the Unreal Engine® 3D visualization environment receives it. To check the block execution order, right-click the blocks and select Properties. On the General tab, confirm these Priority settings:
Simulation 3D Scene Configuration —
0
Simulation 3D Three-Wheeled Vehicle —
-1
For more information about execution order, see Control and Display Execution Order.
