Simulink - Simscape Tire (Magic Formula) to output lateral components

I am building a Torque Vectoring Simulink model and require the lateral components of the tire model. The Simscape Tire (magic Formula) block only considers longitudinal components. I am wondering if there is an easy way to adapt the outputs of this tire model to consider lateral components as well (using circle of forces models) or if you would reccomend to build my own block and tire model.

You have a few options for a tire with longitudinal and lateral dynamics that integrates well with Simscape.

1. MFeval on the File Exchange is a Magic Formula-based tire model that has the dynamics you request and much more. It requires a lot of parameters (usually provided in a .tir file) and there is a example parameter set included in the submission.
2. Simcenter Tire (formerly known as Delft Tyre) is an industry standard tire model which has interfaces to MATLAB and Simulink. It is part of the MathWorks partner program. It also requires parameters, often the form of a .tir file.
3. For low speed maneuvers, you could look at the Spatial Contact Force block. For this, you would need to create a Simscape Multibody interface, which may be more than what you are intending to do.

You can see examples of how to use these tire models in the Simscape Vehicle Templates, a configurable vehicle model created primarily in Simscape which is free to download.
