Improving the Reliability of Automotive Systems

The automotive industry is changing rapidly with technological advances and a focus on greener and safer vehicles. Original equipment manufacturers (OEMs) are pushing for electronic innovation. At the same time, suppliers, many of whom focus solely on mechanical products, are urged to incorporate electronics into their portfolios to avoid commoditization. Successfully meeting this challenge offers the potential for differentiation and increased value but also opens the door to competition from technology companies looking to enter the industry. The automotive industry is adapting to change and facing new challenges while building on past experience. With the increasing interaction of electronics in vehicles, ensuring the functional safety of mechatronic systems is critical. Accurate manufacturing and repeatability are essential, as is the alignment of electronic and mechanical components for exact measurements and movements. Similarly, software development requires procedures for verifying and validating behavior to avoid bugs and enable secure updates when needed. The integration of electronics into vehicles has raised cybersecurity concerns. This raises questions about how to ensure the safety and security of cars, what to do when vulnerabilities are discovered, and how long a vehicle should receive updates. In addition, using artificial intelligence-based systems in vehicles presents new challenges. As these systems are “black boxes,” ensuring their reliability and safety is more complicated. OEMs and TIER 1 suppliers must comply with standards and regulations to ensure the reliability of automotive systems. Achieving compliance requires significant time, resources, and changes to internal processes, but ensuring a safe, reliable, and cyber-secure fleet is essential. This chapter provides an overview of relevant standards, guidelines, and recommendations, proposing the Automotive SPICE framework as a tool for effectively implementing them within an organization.
