How to implement CVT transmission

Question

Hello,

First of all I would like to thank you a lot for your work, it's amazing to see the potential that we get by using this asset, everything is working fine it's really helpful

Currently I am trying to reproduce common cars, and which some of them are using CVT, in the following documentation here : https://vehiclephysics.com/user-guide/extending-vpp/ I've noticed that CVT is mentioned, but I couldn't get anything working

Would there be any documentation/examples of scripts that reproduce CVT transmission as mentioned in the documentation ? Or any help on that topic ? I would really appreciate it

Thanks a lot and wishing you a good day

You could start with the Custom Vehicle example here:

And with the Custom Block example here for a custom Gear block:

In the custom vehicle code, the direct drive motor is connect to the differential. Instead, you would connect the direct drive motor to the custom Gear block, then this one to the differential. Then changing the ratio property in the Gear block in real time would be equivalent to a CVT. You could simply calculate the ratio based on the rpm at the wheels.

Note that implementing custom vehicles or custom blocks requires a paid edition of Vehicle Physics Pro. Customization is not available in the Community edition of VPP.
