What is SAE?
The Society of Automotive Engineers (SAE) plays a pivotal role in shaping the future of the automotive industry by developing and setting standards that address vehicle performance, safety, and communication protocols. These standards are not only critical for traditional automotive companies but also influence the evolution of electric vehicles (EVs), autonomous driving technologies, and cybersecurity measures within the industry.
For instance, electric vehicle manufacturers like Rivian are pushing the boundaries of innovation to achieve net-zero emissions by 2040, aligning with SAE's environmental and sustainability guidelines. SAE's influence extends to the robotics field as well, with companies like GrayMatter Robotics leveraging AI to enhance manufacturing processes, ensuring that products meet the high-quality standards set by the SAE.
In the realm of cybersecurity, the joint efforts of the International Organization for Standardization (ISO) and SAE have led to the ISO/SAE 21434 standard, which is instrumental for organizations to manage risk and define cybersecurity policies. This standard encompasses an exhaustive list of security categories, emphasizing the importance of cybersecurity across all levels of automotive design and production.
The future of vehicle design is also being shaped by SAE standards, with the shift towards zonal architectures that streamline the electrical distribution system. This evolution is critical as the industry adapts software architectures from the tech sector to meet the intensive demands of automotive applications.
Autonomous driving (AD) is another area where SAE's classification system is invaluable, providing a clear framework for the development of self-driving technologies. The six levels of automated driving defined by SAE serve as a roadmap for manufacturers, regulators, and consumers alike.
With the automotive market demanding unparalleled levels of quality and safety, SAE's role is more crucial than ever. The industry's economic impact is significant, directly and indirectly employing over 1.3 million Americans with wages and benefits totaling approximately $104.29 billion, and generating nearly $41 billion in taxes annually. These figures underscore the industry's importance and the key part SAE standards play in its ongoing success and innovation.
The Importance of Definitions
The automotive landscape has undergone a seismic shift with vehicles transforming from mechanical marvels to software-driven machines. This metamorphosis necessitates a shared vocabulary to ensure precision and coherence across the industry. The Society of Automotive Engineers (SAE) plays a pivotal role by providing a lexicon of autonomy, delineating the levels of automated driving. This classification system, recognized throughout the industry, clarifies the degree of automation in vehicles, from Level 1, where a single aspect is automated, to fully autonomous vehicles.
The significance of standardization is underscored by the ISO/SAE 21434 standard, developed jointly by the International Organization for Standardization (ISO) and SAE International. This standard sets the benchmark for cybersecurity in road vehicle systems, addressing the entire spectrum from integrated circuits to software and firmware. It mandates thorough training and qualifications for stakeholders involved in the product lifecycle, ensuring that cybersecurity is integral to the organizational fabric.
As vehicles evolve into 'smartphones on wheels,' with updates and new features being pushed over the air, the concept of a software-defined vehicle (SDV) is no longer a futuristic notion but a present reality. This paradigm shift is likened to the evolution of mobile phones, which have transitioned to a standard form factor distinguished primarily by their software capabilities.
The progression towards software-defined electric vehicles (EVs) is not only about enhancing user experiences but also about adapting to new safety standards that have yet to be regulated. Historically, automotive safety innovations such as airbags and stability control were market-driven before becoming regulated. Similarly, the industry is navigating the uncharted waters of autonomous driving regulation, emphasizing the importance of data tracking and incident classification to ensure safety and foster innovation.
In this dynamic environment, clear definitions and standards are the linchpins of collaboration and progress. They prevent miscommunication and foster synergy among engineers, developers, and business leaders, such as those from Thoughtworks, who are at the forefront of automotive and embedded automotive development. As vehicles continue to advance, these definitions and standards will remain the bedrock of a safe, efficient, and interconnected automotive industry.
Types of SAE Definitions
The Society of Automotive Engineers (SAE) has established an intricate framework of definitions vital for the progression and clear understanding of automotive technology. Among these are:
-
Terminology Definitions, which serve as the bedrock for clarity within the industry by providing exact explanations of the technical terms and abbreviations prevalent in automotive circles.
-
Performance Definitions, which are crucial as they establish the benchmarks and criteria for assessing the functionality of vehicles, their components, or entire systems. This is particularly relevant in the context of autonomous driving, where vehicles are expected to navigate without human input, relying heavily on performance metrics to ensure safety and reliability.
-
Specification Definitions, which are detailed blueprints that outline the essential specifications and standards that automotive parts, systems, or methodologies must meet. These definitions are integral in ensuring the seamless integration and functionality of the numerous electronic systems within modern vehicles, which can include upwards of 3000 chips.
-
Protocol Definitions, which dictate the communication standards and protocols necessary for data exchange within a vehicle's various systems or between the vehicle and external apparatus. This aspect is crucial in maintaining cybersecurity measures, as outlined in ISO/SAE 21434, to prevent risks and harm from system failures.
Each of these definitions plays a pivotal role in advancing automotive technology, not only to enhance the driving experience but also to uphold the highest levels of safety and quality as vehicles become increasingly connected and autonomous. The SAE's lexicon of autonomy, with its six levels of automated driving, is a testament to the organization's commitment to creating a shared language that promotes understanding and innovation across the industry.
