Automotive safety and driver convenience rely on increasingly complex simulation-driven systems that require managing thousands of heterogeneous models. Renault uses a SysML-based Model Identity Card (MIC) together with a Model-Based Simulation (MBSi) approach, yet simulation model management remains difficult. This paper reviews Renault’s current model management practices, highlights shortcomings in modelling and simulation for complex automotive systems, and uses ADAS/AEB as illustrative cases. It then identifies key team challenges and proposes research directions for validation and verification management based on state-of-the-art methods.

These systems are increasingly complex to build and maintain. To develop these systems Renault makes intensive use of simulation and must deal with thousands of models. This huge number of models must be well managed. To manage these models, Renault has developed the SysML-based Model Identity Card (MIC), used with a Model-Based Simulation (MBSi) approach. However, despite this first solution, managing simulation models remains a difficult task. In this paper, we describe the current simulation model management approaches used at Renault, and their shortcomings and challenges in the modelling and simulation of complex automotive systems. We use Advanced Driver Assistance System (ADAS) and its Automatic Emergency Breaking (AEB) sub-system as examples to illustrate the utilization of the MIC and demonstrate current practices. From these examples, we derive main challenges faced by the virtual simulation team and propose research directions to solve them, based on state ofthe art methodologies for simulation models’ validation and verification management.

New techniques and approaches are being developed to facilitate the design and implementation of these systems, based on decomposing a system into its sub-systems following a “divide and conquer” simplification strategy, while also supporting collaborative work allowing stakeholders to (semi- )independently develop their respectiv

FAQs

What problem does Renault’s virtual simulation team face in model management?

Renault must manage thousands of heterogeneous simulation models across many simulation platforms, making model organization and lifecycle management challenging for complex automotive systems.

How does the Model Identity Card (MIC) support simulation model management?

The MIC is a SysML-based template that describes simulation models and is used with a Model-Based Simulation (MBSi) approach to help manage the large model collection.

How are ADAS and AEB used in the paper?

The paper uses the ADAS system and its Automatic Emergency Breaking (AEB) sub-system as concrete examples to show how MIC is utilized and to reveal current practices and limitations.
