tireModel Class
Description
This class requires Extended Tire Features for Vehicle Dynamics Blockset.
Store model parameters, execute model solver computations, plot model behavior, and export
model data with the tireModel
superclass.
Creation
You can create tire model objects in three different ways.
Use
tireModel.new
to create a tire model object with default values.Use
tireModel.builtin
to create a tire model object from a built-in tire model.Use
tireModel.import
to import an existing tire model parameter set into a tire model object.
Note
Nonempty properties specified as a column vector must all be the same length.
