Automotive Engineering - August 2022

Overview

The August 2022 issue of Automotive Engineering presents a comprehensive exploration of the latest trends, innovations, and challenges in the automotive industry, particularly focusing on electric vehicles (EVs) and advanced manufacturing techniques.

Cover Story: Rivian R1T Teardown

The issue features an in-depth cover story on Rivian's R1T, a pioneering electric pickup. This comprehensive teardown reveals the vehicle's praiseworthy build quality and innovative design, while also highlighting some lapses in manufacturability. The analysis provides insights into how Rivian is addressing the complexities of producing an electric vehicle in a competitive market.

Electrification and NVH Innovations

A significant focus of this issue is on the impact of electrification on noise, vibration, and harshness (NVH) materials. As electric vehicles become more prevalent, the need for innovative NVH solutions is critical. The magazine discusses how skateboard platforms and high-frequency motor noise are pushing manufacturers to develop new materials and countermeasures to meet lower decibel thresholds, ensuring a quieter and more comfortable ride for consumers.

Additive Manufacturing Insights

The issue also delves into the optimization of design for additive manufacturing (3D printing). An expert from a leading additive manufacturing specialist shares valuable insights on avoiding common pitfalls associated with 3D printing. The article emphasizes the importance of understanding process limitations and how to work around them to achieve successful outcomes in automotive applications.

Electrical Architectures and Real-Time Processors

Another key feature discusses the zonal electrical and electronic (E/E) revolution, highlighting how NXP's new generation of software-compatible processors is set to accelerate systems consolidation and enhance performance. This advancement is crucial as vehicles become increasingly reliant on complex electronic systems, necessitating robust and efficient processing capabilities.

Industry Challenges and Quality Concerns

The magazine addresses the growing concerns regarding vehicle quality, particularly in the context of electric and hybrid vehicles. A report from J.D. Power indicates that overall vehicle quality has dropped to a 36-year low, with a notable increase in problems per 100 vehicles. Owners of battery-electric and plug-in hybrid vehicles report more issues compared to traditional internal combustion engine models, primarily related to complex electronics and software. This trend raises questions about the industry's ability to maintain quality as it shifts towards electrification.

Expert Opinions and Future Directions

In an editorial piece, Lindsay Brooke, the Editor-in-Chief, discusses the challenges posed by the increasing complexity of automotive electronics. He emphasizes the need for closer collaboration between Tier-1 designers and integrated-circuit creators to ensure reliability in automotive electronics. The industry must address these challenges to avoid a repeat of past issues associated with electrical systems, often referred to as the "Prince of Darkness" in automotive lore.

Product Briefs and Industry Events

The issue includes product briefs that highlight new technologies and innovations in the automotive sector. One notable mention is ITG Electronics' introduction of high-current flat wire inductors designed for industrial and automotive applications. These inductors promise superior power ratings and reduced weight and space requirements, showcasing the ongoing advancements in component design.

Additionally, the magazine promotes the On-Board Diagnostics Symposium Americas, scheduled for September 13-15, 2022, in Garden Grove, CA. This event aims to bring together technical experts, regulators, suppliers, and OEMs to discuss the current issues and future challenges in on-board diagnostics.

Subscription Information

For readers interested in subscribing, the magazine outlines subscription prices for nonmembers, including 5 for North America and 5 for overseas subscriptions. Digital subscriptions and single copies are also available at each.

Conclusion

Overall, the August 2022 issue of Automotive Engineering provides a rich tapestry of insights into the evolving landscape of the automotive industry. With a strong emphasis on electric vehicles, innovative manufacturing techniques, and the challenges of maintaining quality in a rapidly changing environment, this issue serves as a valuable resource for industry professionals and enthusiasts alike. The articles encourage readers to consider the future of automotive engineering and the critical role that technology and collaboration will play in shaping it.
