Model a CVT from fundamental equations using standard simulink blocks

I have prepared a model for HEV using mathematical equations for all components using standard simulink blocks, however not able to find appropriate equations to model a CVT. Please help

[Ankit]

there are online literature available

for e.g basic kinematics can be found in the link below:

The following paper also describes the modeling of CVT in MATLAB/Simulink

https://www.researchgate.net/publication/282996810_Comparing_of_single_reduction_and_CVT_based_transmissions_on_battery_electric_vehicle

And other source is File Exchange may be there you can find anything.

Thanks ! Please can you suggest me a way to build/ find lookup table for CVT gear ratios ?

You know that SImulink library has several lookup table blocks.

Here is the nice tutorial how to employ and set up look up tables of Simulink:

Here is a nice project on ATV and CVT model design in Simulink environment:
