    Overview

    Model-based development is spreading wide in the automobile industry

    The CASE (Connected, Autonomous, Shared, Electric) approach to mobility, which will change the automotive industry, is highlighting the need for model-based development (MBD). MBD is a development method using the simulation of automotive control, automotive components, vehicle dynamics, and traffic environments such as roads, pedestrians, bicycles, traffic signs, and other vehicles, thereby reducing the time and costs required for the development of vehicle control systems. However, many successful applications of MBD have been limited to the designing of a single control unit.

    Challenges faced by the dissemination of model-based development

    As a result of the trend in recent years with vehicle systems to incorporate a large number of components from multiple suppliers, the automotive industry tries to perform largescale simulations of multiple interconnected models. However, there are many challenges to be overcome to realize such simulations, including the need for cooperation among multiple suppliers to enable vehicle-level simulation and the difficulty of collecting all of the necessary models. Since models are embodiments of their design specifications, many suppliers are unwilling to provide their models to external parties. Furthermore, it is a highly complicated task to accurately connect the thousands of signals (variables) transmitted across vehicle control systems.

    Even if these issues are overcome, processing a simulation linking many cooperating models will constitutes a heavy load, that will take a long time to execute on a single PC.

    • Connecting models is hard

    Connecting multiple signal lines without any mistakes is a challenge, and it takes considerable man-hours to investigate whether a problem is a connection error or a bug.

    • Models can't be disclosed

    Design data for models is confidential information belonging to each company, and they must connect their development environments without disclosing this information to other companies.

    • Simulation is slow

    Operation slows down and it takes more time to execute the simulations when putting together multiple models on one computer.

    Value

    The next evolution for model-based development

    Model-based development is gaining in popularity with car manufacturers and suppliers. To apply this development method more broadly and on a larger scale, the Distributed Co-Simulation Platform connects numerous models, various development tools, and different companies in cyberspace, to provide an environment that enables joint verification. This allows automotive makers to perform earlier verifications for complex automotive control systems connected to multiple systems such as autonomous driving and advanced driving assist, improving quality while drastically boosting productivity.
