Vehicle Dynamics Blockset provides preassembled automotive vehicle dynamics reference applications for passenger cars, trucks, and two-wheelers. The blockset includes a component library for propulsion, steering, suspension, vehicle body, brakes, tires, and driver models, as well as component and supervisory controllers. You can use the built-in interface with Unreal Engine® to visualize simulations and communicate scene information back to your model.
Vehicle Dynamics Blockset offers the Virtual Vehicle Composer app for configuring and parameterizing models, as well as prebuilt workflows for Kinematics and Compliance (K&C) testing and calibrating models from test data. You can use these models for ride and handling analyses, chassis controls development, software integration testing, and hardware-in-the-loop (HIL) testing. The models are open, so you can incorporate your own subsystems and customize them as needed.

Vehicle Dynamics Blockset FAQs
Vehicle Dynamics Blockset provides preassembled reference applications for automotive vehicle models, along with component libraries and tools for modeling and simulating vehicle dynamics in a virtual 3D environment.
The blockset provides preassembled reference applications for passenger cars, trucks, two-wheelers (e.g., motorcycles) and three-wheelers (e.g., tuk-tuks).
The blockset includes component libraries for propulsion, steering, suspension, vehicle body, brakes, tires, and driver models, as well as component and supervisory controllers.
Yes, Vehicle Dynamics Blockset supports an interface with Unreal Engine to visualize simulations using photorealistic 3D scenes and communicate scene information back to your model. Vehicle Dynamics Blockset extends the Unreal Engine interface provided by Simulink 3D Animation, adding automotive-specific 3D assets such as passenger cars, tractor trailers, motorcycles and three-wheeled vehicles.
The Virtual Vehicle Composer is an app for interactively configuring and parameterizing pre-built vehicle models.
Yes, the models are open and customizable. You can incorporate your own subsystems and customize them as needed. This includes adding custom Simulink or Simscape component models, as well as integrating components from third-party simulation software in the form of S-functions or FMUs.
You can use Vehicle Dynamics Blockset for ride and handling analyses, chassis controls development, software integration testing, hardware-in-the-loop (HIL) testing, and testing ADAS and automated driving control features.
The blockset includes preassembled maneuvers for common ride and handling tests, including double-lane change, slowly increasing steer, sine with dwell, fishhook, and split-mu braking tests.
Yes, the models are open and customizable. You can use Simulink and Stateflow to define your own maneuvers, then connect them to the vehicle model.
Yes, the blockset provides several tools to help you parameterize your models, including the Virtual K&C Test Lab reference application and Tire Manager app. You can use the Virtual K&C Test Lab reference application to rung K&C tests, import test data, and fit suspension models to that data. With the Tire Manager app and associated MATLAB APIs, you can import and preprocess measured tire data, perform visualization and model fitting, and export tire model parameters for use with Simulink.
Yes, you can use these models for hardware-in-the-loop (HIL) testing and achieve real-time execution using Simulink Real-Time, enabling controller validation and system testing. The models are compatible with all major HIL providers.
Yes, you can connect the models to Unreal Engine for the visualization and common gaming hardware for the steering wheel and pedal inputs, then drive your vehicle around in a virtual 3D environment.
Vehicle Dynamics Blockset provides library blocks for Magic Formula 6.2, Dugoff and Fiala tire models. It also supports the CPI and STI tire interface definition. The Extended Tire Features for Vehicle Dynamics Blockset add-on includes predefined parameter sets for a wide range of vehicle classes, from motorcycles, to small passenger cars, to pickup trucks and commercial vehicles. It also includes the Tire Manager app and MATLAB APIs that you can use to fit tire models and convert between various tire model types, e.g., converting from Magic Formula 5.2 to Magic Formula 6.2.
That depends on the controller and the parameter values provided. When parameters can be taken from physical test data (e.g., K&C test data, tire test data), the models can reproduce real world results quite well. Because Vehicle Dynamics Blockset includes generic, representative controls, the vehicle may behave differently than it would with production controllers.
