Overview of HILS Engineering Services

  • Overview1

    Typical Control System Development Flow and Challenges

    Defects Discovered in the Final Stage Impose a Heavy Burden

    If defects are discovered in the final stage (system testing), it leads to rework all the way back to system design, creating a significant burden on development. To prevent this, model-based design and verification are expected to play a key role.

    Systems Becoming More Advanced and Complex

    Increasing Demand for Model-Based Development

    In recent years, automotive control systems have become increasingly advanced and complex, heightening the need for sophisticated development environments—particularly Model-Based Development (MBD).

    Work Style Enabled by Model-Based Development

    The Role of HILS in Model-Based Development

    In Model-Based Development, control algorithms are developed using MILS and SILS, while HILS is utilized for functional verification of the implemented ECU. HILS plays a particularly crucial role during the verification phase.

  • Overview6

    Basic Concept of HILS

    Streamlining Verification Work

    To verify the target system hardware, such as an ECU, you must prepare the system to be controlled (such as the vehicle itself) as well as input systems like the steering setup, which requires a tremendous amount of effort. By virtualizing these controlled systems and input systems into a desktop environment where the target system can be evaluated, you can achieve significant labor savings and reduce physical space requirements.

    HILS System Architecture

    Virtualized Plant Models and Actual ECU (+ Actual Loads)

    The ECU (+ loads) targeted for evaluation uses actual hardware as-is. All other environment elements (vehicle, inputs, etc.) are virtualized and hosted on the main CPU of the HILS unit. CAN controller boards and AD/DA boards mounted in the HILS unit are wired directly to the ECU to transmit and receive signals. The test environment is controlled via Ethernet communication between the main HILS unit and a host PC.

Model Construction Services for Various Applications

  • Creation of Models Hosted on the HILS CPU

    We build models, control panels, and test scenarios tailored to customer requirements. These models include plant models as well as signal transmission and reception models.

  • Broad Support for Model Creation

    We cover a wide range of models to be loaded onto the HILS CPU, including signal I/O models for CAN, CAN-FD, and AD/DA, as well as vehicle models, ECU models, and environment models. We also support the creation of test scenario models.

CG Creation Services

  • Creation of CG for ADAS Cameras and Road CG

    We provide creation services for ADAS camera CG and road CG, utilizing commercial tools specified by the customer. Furthermore, if CG input into the ECU is required, we construct the CG input system in collaboration with image conversion board vendors.

Maintenance Services

  • Maintenance of Various Models, Test Scenarios, and Control Screens

    As the specs of the target system change or expand, we update the various models running on the HILS CPU. We also handle any necessary updates to test scenarios, control screens, and other elements.

Co-creating unprecedented evolution through unstoppable technology.
