hello!

I want to know how Vehicle Body 3DOF block calculate tire lateral force.

It seems that the tire corner stiffness multiplied by tire slip angles is not equal to tire force.

I want to know how to calculate tire force or is there any block can output the tire lateral force along the tire-fixed y-axis ?

thanks！
