How to configure coordinate systems of Vehicle Dynamics Blockset?

In the doc: https://de.mathworks.com/help/vdynblks/ug/coordinate-systems-in-vehicle-dynamics-blockset.html

You can find the following:

The right-hand rule establishes the X-_Y_-_Z_ sequence and rotation of the coordinate axes used to calculate the vehicle dynamics. The Vehicle Dynamics Blockset 3D simulation environment uses these right-handed (RH) Cartesian coordinate systems defined in the SAE J670<https://de.mathworks.com/help/vdynblks/ug/coordinate-systems-in-vehicle-dynamics-blockset.html#mw_670a15dc-8cb4-4f63-90f1-7b6b33632837 [2]> and ISO 8855<https://de.mathworks.com/help/vdynblks/ug/coordinate-systems-in-vehicle-dynamics-blockset.html#mw_99db286e-ed1d-457c-8065-1ab3611f8338 [3]> standards:

• Earth-fixed (inertial)
• Vehicle
• Tire
• Wheel

The coordinate systems can have either orientation:

• Z-down — Defined in SAE J670<https://de.mathworks.com/help/vdynblks/ug/coordinate-systems-in-vehicle-dynamics-blockset.html#mw_670a15dc-8cb4-4f63-90f1-7b6b33632837 [2]>
• Z-up — Defined in SAE J670<https://de.mathworks.com/help/vdynblks/ug/coordinate-systems-in-vehicle-dynamics-blockset.html#mw_670a15dc-8cb4-4f63-90f1-7b6b33632837 [2]> and ISO 8855<https://de.mathworks.com/help/vdynblks/ug/coordinate-systems-in-vehicle-dynamics-blockset.html#mw_99db286e-ed1d-457c-8065-1ab3611f8338 [3]>

How to change the direction for Z in the blocks?

[MathWorks Support Team]

In regard of the Z-up/down, presently only the SAE Z-down is supported. These can be converted to ISO using standard transformation matrix operations.

The feature to switch in between these different standards will be maybe implemented in a future release.
