Get Started with the Extended Tire Features for Vehicle Dynamics Blockset

R2026b

The Extended Tire Features for Vehicle Dynamics Blockset™ support package provides a set of tools to work with tire data and integrate tire models into vehicle simulations. Tire data describes the operating conditions of a tire, and tire models describe tire behavior with mathematical models. Calculating the tire responses requires both tire models and tire data.

Using the tireData and tireModel functions and methods, or the Tire Manager app, you can:

• Import and preprocess tire data.

• Create tire models from the supported tire model types:

  • Magic Formula 5.2 — Choose the Magic Formula 5.2 tire model when you need a high level of accuracy for high-fidelity vehicle dynamic simulations.

  • Magic Formula 6.2 — Choose the Magic Formula 6.2 tire model when you need to model a larger range of camber angles and inflation pressure sensitivity.

  • Dugoff — Choose the Dugoff tire model when you need to represent combined slip conditions, but you want a simpler tire model that is easier to fit with fewer parameters.

  • Fiala — Choose the Fiala tire model when you need a simple tire model with few parameters that is easy to fit.

• Convert between different tire model types.

• Perform computations on tire data using tire model parameter sets to calculate tire responses.

• Fit tire models to specified tire responses.

• Export tire model parameter values to a file or Vehicle Dynamics Blockset wheel blocks for simulations.

These tools provide a complete workflow to fit and simulate tire models. To access the tools for data preprocessing, visualization, tire response calculation, and tire model fitting, see Install Support Package.

Workflow Options

You can analyze tire data and fit tire models using the Tire Manager app or programmatically.

Tire Manager App Workflows

Follow these examples demonstrating Tire Manager app workflows.

Step		Goal
1	Import Tire Measurement Data for Analysis	Import data from a TYDEX v1.3 file to prepare for model fitting, and export the edited tire data to a file.
2	Convert Tire Model for Use in Supported Simulink Block	Import a Magic Formula 5.2 tire model to convert a Magic Formula 6.2 tire model and export the converted tire model to the Combined Slip Wheel 2DOF block.
3	Fit a Tire Model to Tire Measurement Data	Import tire measurement data and fit a Magic Formula 6.2 tire model to tire data.

Programmatic Workflows

Follow these steps for examples demonstrating programmatic workflows.

Step		Goal
1	Example Tire Data	Get familiar with the example data used to display the capabilities of the Extended Tire Features for Vehicle Dynamics Blockset support package.
2	Import and View Tire Data	Import data from a Tyre Data Exchange Format (TYDEX) v1.3 file to a tireData object.
3	Plot Tire Data for Visual Inspection	Use the plot function to visualize data within a tireData object.
4	Plot Tire Model Response for Visual Inspection	Use the plot function to visualize the response of a tireModel object.
5	Plot Tire Model Response with Imported Tire Data for Visual Inspection	Use the plot function to visualize the response of a tireModel object using imported tire data.
6	Fit a Tire Model to Tire Data	Use the fit function to fit a tireModel object to imported tire data.
7	Update Tire Block Parameter Values	Use the set function to update supported tire block parameter values with values from a fitted tire model.
