Full Vehicle Simulation

Create a full vehicle digital twin to accelerate testing and verification of control designs and production hardware

Use rigorous and efficient real-time testing to verify the successful operation of individual components in complex vehicle networks.

In a Simulink full vehicle model, every physical component accurately represents and mimics their behaviors. A virtual vehicle is created as a digital twin so that individual subsystems can be replaced by real devices under test and connected to a simulation environment using the same automotive interfaces and communication protocols as those used in the real car.

Speedgoat real-time target machines guarantee deterministic real-time execution of full vehicle models and provide customizable I/O interfaces such as CAN, LIN, SENT and FlexRay for a seamless connectivity.

“The real-time multi-vehicle simulator, built with Speedgoat hardware, is one of the most important building blocks in testing our autonomous racing algorithms before going out on the racetrack against our competitors."

Featured Application Use Cases

Full Vehicle Simulation

Use prebuilt, customizable reference applications from Vehicle Dynamics Blockset™ and Powertrain Blockset™ to create accurate digital twins of vehicles. Simulate passenger vehicles, trucks, trailers and motorcycles together with 3D visualization. Create high-fidelity models of electric motors, fuel cells, multibody suspensions or cooling systems with Simscape^® by assembling and connecting fundamental components like resistors, capacitors and voltage sources.

Use automotive I/O buses to perform hardware-in-the-loop (HIL) simulation and rapid control prototyping (RCP) and prototype intelligent assistance systems with Automated Driving Toolbox™.

Use the Functional Mock-up Interface (FMI) to easily import, reuse and share tool-independent plant models.

Testing Safety and Assistance Systems

Deterministic real-time behavior is key for sizing safety critical systems. Use simulation to safely test assistance systems and emergency procedures such as emergency braking, lane-keeping assist (LKA) and adaptive cruise control (ACC). If needed, generate raw sensor data from the simulation or process large amounts of sensor data using hardware acceleration and implement powerful model-predictive control schemes.

Environment and Sensor Modeling

Create cuboid-based 3D driving scenarios with the Driving Scenario Designer app or design complex and photo-realistic scenes with the RoadRunner editor. Import prebuilt Euro NCAP tests and OpenDRIVE road networks. Synthesize data for edge-driving scenarios (e.g. control handover and platooning) and verify the performance of the real-time designs in co-simulation with Unreal^® Engine. Incorporate realistic camera, radar and lidar sensor models to generate, record and replay synthetic raw sensor data and ground truth-semantic information.
