How to design a BAJA transmission system ?

I am a beginner, I made this (attached simulink design pic ) while learning from other videos and some basic knowledge of the data. Can you help me with this ? How can I improve this system. (It is baja designed transmission system, consisting a engine, cvt and single reduction gearbox with no differential). I don't know about r port in "Variable transmission ratio" block. Here's a simulink file attached.

You can zip .slx or .mdl and attach the .zip

Walter has directed you to the correct link: https://www.mathworks.com/help/physmod/sdl/ref/variableratiotransmission.html

The input to r port is the gear ratio as the function of time. In your model you have used a signal builder block to represent gear ratio as a function of time which is a correct approach. Just make sure that you have taken the correct gear ratio.

I have tried giving a contant value to the ratio (r port of VTR), but results are not showing up.
