The automotive industry is inherently tied to life and property, meaning poor product design or reliability defects can result in substantial compensation costs for manufacturers. This industry must transcend the conventional mindset of the consumer electronics sector, as there is absolutely no room for compromise when it comes to quality and reliability requirements.

"X-by-wire" is an engineering term, referred to in Chinese as 電子線控 (electronic control-by-wire). It signifies that a specific component is controlled by electronic signals rather than mechanical linkages or hydraulic systems. Since the term "by-wire" is used as a suffix in English, it is collectively referred to as "X-by-wire." The "X" represents the original system or functionality.

With the annual advancements and maturation of LED technology in the automotive sector, its energy-saving and eco-friendly characteristics have led to an increasing number of vehicles adopting LED light sources to replace traditional ones. LEDs consume significantly less power than conventional bulbs, resulting in a higher lumen output per unit of power compared to traditional light sources. Additionally, electronic solutions enable greater diversity in the design, effects, and functionality of LED automotive lighting.

The number of processors, sensors, memory devices, and other electronic components used in automotive cabins is steadily increasing. These new features reduce the risk factors associated with driving behavior. The operation of these bus-connected automotive HMI subsystems, which leverage connectivity and autonomous driving technologies to enhance driving safety, must prioritize reliability and predictability as fundamental principles.

To meet the high standards required for automotive electronic products in terms of operating temperature, durability, and reliability, engineers and suppliers must adopt more advanced technologies and implement stricter testing procedures to achieve an optimized design approach.

Automotive Functional Safety Requirements
The automotive industry is one where system failures are simply not tolerated. Any occurrence of failure exposes vehicle manufacturers to significant risks, including lawsuits, compensation claims, and severe damage to their reputation. To prevent system failures, a stringent and reliable development process must be established to guide system development engineers.

During the development of automotive electronics, the demand for cost efficiency, reliability, and speed has led to the widespread adoption of embedded systems. However, this has also brought challenges due to the lack of standardized software design. As systems become increasingly complex, design, maintenance, and upgrades have become more difficult. Therefore, the push for standardization of automotive software has long been a core need and concern within the automotive industry. From the early OSEK/VDX to the more recent AUTOSAR, these frameworks are the result of such demands.

As the automotive industry's focus continues to shift from mechanical and hardware systems to software and electronic controls, the rules of competition are being rewritten. In the 20th century, the internal combustion engine was the core of automotive innovation, but today, robust and functionally safe software, powerful computing platforms, and advanced sensors are increasingly taking on this central role.

As vehicle electronic architectures expand to handle more ECUs and multiple systems, the automotive ecosystem is undergoing a transformation driven by major developments in connectivity, electrification, and shared mobility. OEMs and tier-1 suppliers are now seeking to adjust their product strategies and business structures to meet industry trends and demands.
