  • Toyota Relies on SIL Simulation from dSPACE to Improve Electrification Development

    Of particular importance as a basis for new vehicle development is the powertrain with its corresponding ECUs. To develop and validate the powertrain, Toyota has strongly promoted the introduction of model-based development (MBD) and relies on the early use of simulation in the development process. At Toyota, SIL simulation is performed with VEOS.

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.

PC-Based Simulation of Heterogeneous Models

VEOS offers a variety of functions to simulate heterogeneous Models:

  • Support of various model types: Simulink and TargetLink models, FMUs, virtual ECUs, and ECU networks in a single environment directly on your PC.
  • 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.
