VEOS

Platform for PC-based simulation of models and ECU network communication

VEOS is a PC-based simulation platform for electronic control unit (ECU) software validation in many development stages. It lets you simulate a multitude of different models – from function models to networks of virtual ECUs, bus systems and vehicle models – even in early phases of development.​​​​​​​

  • Support of FMI 3.0

    VEOS supports the FMI 3.0 standard that enables the exchange of highly complex data and therefore is ideally suited for sensor models. In Addition, FMI 3.0 can be the basis for a future V-ECU standard.

Application Areas

dSPACE VEOS is a PC-based simulation platform that promotes SIL testing for the development of electronic control units (ECUs):

  • Simulating a wide range of different models, such as function models, Functional Mock-up Units (FMUs), virtual ECUs (V-ECUs), and vehicle models, in the early development stages independent of any specific simulation hardware.
  • For multi-model scenarios, VEOS supports importing, connecting, and running any number of function and plant models based on Simulink or Functional Mock-up Interface (FMI), thereby extending the scope of the applications.

Key Benefits

VEOS runs on standard PCs, which gives function developers, software architects, and ECU testers a variety of valuable options for SIL testing during the early project phases:

  • Available for Windows and Linux operating systems.
  • Easy integration into cloud-based solutions for SIL testing.
  • Support for co-simulations with third-party tools.
  • Flexible integration into the development process.
  • Software-software integration can be tested from component to system level.
  • Sophisticated environment models can be integrated with virtual ECUs to validate complex controller strategies or simulate and test entire virtual vehicles.
  • Continuity throughout the entire tool chain and easy transition from SIL to HIL testing.

Systematic Extension to the dSPACE Tool Chain

  • Open interfaces to connect and use existing tools.
  • Easy reuse of data, tools, and models between HIL simulations and SIL testing.

  • Support of Simulink implementation containers (SICs).
  • Identical user workflow across all supported model types for importing and connecting FMUs to other model interfaces.
  • Variable and parameter access during simulation via ControlDesk, AutomationDesk, and XIL API.
  • Debugging the source code.

Comprehensive Bus Simulation

With VEOS your bus simulation needs are covered:

  • Simulation of virtual ECU networks.
  • Support of automotive Ethernet, CAN, and LIN bus communication, including all bus-specific effects, without any additional hardware.
  • Integration of bus simulation containers (BSCs) generated by the Bus Manager.

Efficiently Integrating Various Modeling Approaches

Compliance with FMI ensures that models created in various modeling tools can be exported as Functional Mock-up Units (FMUs) and that these FMUs can readily be integrated in VEOS-based virtual validation projects. In such projects, FMUs can be integrated together with other FMUs, virtual ECUs (V-ECUs), and Simulink® models. The user workflow for importing and connecting FMUs to other model interfaces is identical for all supported model types. Variable and parameter access during simulation is supported by ControlDesk, AutomationDesk and XIL API.

Functional Mock-up Interface

dSPACE supports the open FMI standard for an easy integration of simulation models from various sources.

 Support of Multisensor Applications
