Model-based development (MBD) is important in the automotive industry for enhancing efficiency, reliability, and quality in vehicle design and production. By using computer models to simulate and test vehicle systems early in the design process, MBD reduces the need for costly physical prototypes and speeds up development. It allows for extensive testing under various conditions, ensuring early detection and solution of potential issues, which improves overall vehicle reliability. MBD also helps manage the complexity of modern vehicles, supports the integration of mechanical, electrical, and software components, and ensures compliance with regulatory standards. It is essential for the development of advanced technologies like autonomous driving, and electric vehicles, and enabling faster innovation.
