INTRODUCTION

Model-Based Design (MBD) has revolutionized the development of automotive controllers, enabling faster and more accurate design iterations and improved quality of the final product. MBD involves the creation of a model that represents the system being designed, which is then used to simulate and test the system's behavior before it is built. The use of MBD in automotive controller development has become increasingly popular due to the advantages it offers, such as reducing development time and cost, improving system performance, and enabling easier integration of complex systems.

However, the success of MBD relies heavily on the definition of clear and comprehensive system requirements. The system

requirements define the functionality, constraints, and performance requirements of the system, which are used as the basis for designing and testing the model. Without well- defined system requirements, the MBD process can become inefficient, leading to delays and errors in the final product [1-5].

The purpose of this paper is to provide a framework for defining system requirements for MBD in automotive controller development. The framework outlines a step-by- step approach for defining system requirements, from identifying system stakeholders to documenting system constraints. By following this framework, developers can ensure that they have a clear and comprehensive understanding of the system requirements, which can help to reduce errors and improve the efficiency of the development process.

The paper begins by providing an overview of MBD and its benefits in automotive controller development. It then discusses the importance of system requirements in the MBD process, highlighting the need for a clear understanding of the system's functionality, constraints, and performance requirements. The paper emphasizes the importance of system requirements in enabling effective communication between stakeholders and ensuring that the final product meets the needs of all stakeholders. The paper then proposes a step-by-step approach for defining system requirements for MBD, which includes identifying system stakeholders and their needs, establishing system boundaries, defining system functions and performance requirements, and documenting system constraints. The paper explains each step in detail and provides examples to illustrate how the framework can be applied in practice [6].

The paper also discusses the importance of validation and verification of the system requirements. Validation involves ensuring that the system requirements accurately reflect the needs of the stakeholders, while verification involves checking that the model meets the system requirements. The paper emphasizes the need for continuous refinement of the system requirements throughout the development process to ensure that they remain relevant and accurate [7-12].

Finally, the paper provides examples of how the proposed framework can be applied to the development of automotive controllers using MBD. The examples demonstrate the importance of defining clear and comprehensive system requirements in the successful implementation of MBD in

automotive controller development. System V-Model is represented in figure 1 below.

In conclusion, the paper provides a valuable framework for defining system requirements for MBD in automotive controller development. The proposed approach can help developers to improve the efficiency and accuracy of the development process, resulting in higher quality and more reliable automotive controllers [13].

  1. DESIGN COMPLEXITY MBD DESIGN CONSTRAINTS

    The technical design complexity for defining system requirements for Model-Based Design (MBD) in automotive controllers can be considered moderate to high. This is because the process involves several technical aspects, including identifying stakeholders, defining system boundaries, specifying system functions and performance requirements, and documenting system constraints.

    In addition, MBD itself is a complex process that requires a thorough understanding of the system being designed and the modeling tools being used. The design of the model must be carefully crafted to accurately represent the system, and this requires knowledge of both the system and the modeling tools. Moreover, the system requirements must be validated and verified, which involves the use of specialized techniques and tools to ensure that the model meets the specified requirements. This can be a time-consuming and challenging process, particularly in complex systems with many stakeholders and requirements [14-22].

    Overall, the technical design complexity for defining system requirements for MBD in automotive controllers requires a high level of technical expertise and attention to detail. The success of the process depends on the ability of the design team to accurately define the system requirements, validate and verify the model, and continuously refine the requirements throughout the development process.

  2. APPROACH TO DEFINE SYSTEM REQUIREMENTS FOR MBD

    Defining system requirements is a crucial step in the Model- Based Design (MBD) process for automotive controllers. The following is a step-by-step approach that can be used to define system requirements for MBD in automotive controllers:

    • Identify System Stakeholders: The first step is to identify the stakeolders who will be affected by the automotive controller. This includes end-users, customers, designers, and other stakeholders who may have a vested interest in the performance and functionality of the automotive controller. The purpose of this step is to understand the needs and requirements of all stakeholders, and to ensure that their needs are reflected in the system requirements.

    • Establish System Boundaries: The second step is to establish the boundaries of the system. This includes defining the scope of the system, identifying the inputs and outputs of the system, and determining how the system will interact with other systems. This step helps to ensure that the system requirements are clearly defined and that there is a clear understanding of the system's functionality [23-25].

    • Define System Functions and Performance Requirements: The third step is to define the functions that the system must perform and the performance requirements that the system must meet. This includes identifying the key features of the automotive controller, specifying the functional requirements of the system, and defining the performance metrics that the system must meet. This step helps to ensure that the system requirements accurately reflect the needs of the stakeholders [26- 30].

    • Document System Constraints: The fourth step is to document the constraints that may impact the development of the automotive controller. This includes identifying any physical, technical, or operational constraints that may limit the performance or functionality of the system. Constraints may include factors such as cost, size, weight, or power consumption. This step helps to ensure that the system requirements are realistic and achievable [31-35].

    • Validate and Verify System Requirements: The fifth step is to validate and verify the system requirements. This involves ensuring that the system requirements accurately reflect the needs of the stakeholders, that the requirements are complete and consistent, and that the requirements can be verified through testing or simulation. This step helps to ensure that the system requirements are accurate and that the final product meets the needs of the stakeholders.

    • Refine System Requirements: The final step is to continuously refine the system requirements throughout the development process. This involves

      updating the requirements as needed, based on feedback from stakeholders, changes in technology, or changes in the design of the system. This step helps to ensure that the system requirements remain relevant and accurate throughout the development process.

      In summary, the step-by-step approach for defining system requirements for MBD in automotive controllers involves identifying stakeholders, establishing system boundaries, defining system functions and performance requirements, documenting system constraints, validating and verifying the system requirements, and continuously refining the system requirements throughout the development process. By following this approach, design teams can ensure that they have a clear and comprehensive understanding of the system requirements, which can help to reduce errors and improve the efficiency of the development process.

  3. VERIFICATION AND VALIDATION OF SYSTEM REQUIREMENTS

    Validation and verification of system requirements are critical steps in the Model-Based Design (MBD) process for automotive controllers. Validation refers to the process of ensuring that the requirements accurately reflect the needs of the stakeholders and that they can be met by the system, while verification refers to the process of ensuring that the system meets the specified requirements.

    The importance of validation and verification of the system requirements can be summarized as follows:

    • Ensure Accuracy: Validation and verification of system requirements are essential to ensure that the requirements accurately reflect the needs of the stakeholders. Without proper validation and verification, the system may fail to meet the needs of the stakeholders or may not perform as expected.

    • Reduce Errors: Validation and verification can help to reduce errors in the design of the system. By validating and verifying the system requirements, design teams can identify errors and correct them before the system is developed. This can help to reduce the cost of development and improve the quality of the final product.

    • Improve Efficiency: Validation and verification can improve the efficiency of the design process. By identifying errors early in the process, design teams can avoid costly and time-consuming rework later in the development process. This can help to reduce the overall time to market and improve the efficiency of the design process.

    • Ensure Compliance: Validation and verification of system requirements are often required by regulatory agencies or industry standards. By ensuring that the system requirements are validated and verified, design teams can ensure compliance with these requirements and standards.

    • Improve Communication: Validation and verification of system requirements can improve communication between stakeholders. By validating and verifying the system requirements, design teams

      can ensure that all stakeholders have a clear understanding of the system requirements and the expected performance of the system. This can help to improve collaboration and ensure that the final product meets the needs of all stakeholders.

      In summary, validation and verification of system requirements are critical steps in the MBD process for automotive controllers. By ensuring the accuracy of the system requirements, reducing errors, improving efficiency, ensuring compliance, and improving communication, design teams can ensure the successful development of a high- quality automotive controller that meets the needs of all stakeholders.

  4. REFINEMENT OF REQUIREMENTS THROUGH THE DEVELOPMENT PROCESS

    Continuous refinement of the system requirements throughout the development process is an essential part of the Model-Based Design (MBD) process for automotive controllers. It involves continuously updating and improving the system requirements based on feedback from stakeholders, changes in technology, or changes in the design of the system. The importance of continuous refinement of the system requirements can be summarized as follows:

    • Respond to Stakeholder Feedback: As the development process progresses, stakeholders may provide feedback on the system requirements. This feedback may identify new requirements, clarify existing requirements, or suggest changes to the requirements. By continuously refining the system requirements, design teams can ensure that the system meets the needs of all stakeholders.

    • Adapt to Changes in Technology: Technology is constantly evolving, and new technologies may become available during the development process. By continuously refining the system requirements, design teams can ensure that the system takes advantage of new technologies and remains up-to- date.

    • Address Design Changes: The design of the system may change during the development process due to changes in the requirements, changes in technology, or other factors. By continuously refining the system requirements, design teams can ensure that the requirements remain aligned with the design of the system.

    • Ensure Relevance: As the development process progresses, the system requirements may become outdated or irrelevant. By continuously refining the system requirements, design teams can ensure that the requirements remain relevant and aligned with the needs of the stakeholders.

    • Improve Quality: By continuously refining the system requirements, design teams can improve the quality of the final product. Refining the requirements can help to identify errors or omissions in the initial requirements and can help to ensure that the final product meets the needs of all stakeholders.

    In summary, continuous refinement of the system requirements throughout the development process is essential to ensure the success of the MBD process for automotive controllers. By responding to stakeholder feedback, adapting to changes in technology, addressing design changes, ensuring relevance, and improving quality, design teams can ensure that the final product meets the needs of all stakeholders and is of the highest possible quality.
