Development of higher-voltage electrical systems in vehicles has been slowly progressing over the past few decades. However, tightening vehicle efficiency and emissions regulations and increasing demand for onboard electrical power means that higher voltages, in the form of supplemental 48 V subsystems, may soon be nearing production as the most cost-effective way to meet regulations. The displacement of high-wattage loads to more efficient 48 V networks is expected to be the next step in the development of a new generation of mild hybrid vehicles. In addition to improved fuel economy and reduced emissions, 48 V systems could potentially save costs on new electrical features and help better address the emerging needs of future drivers. Challenges to 48 V system implementation remain, leading to discussions by experts from leading car makers and suppliers on the need for an international 48 V standard. Initial steps toward a proposed standard have already been taken.

Aviation propulsion development continues to rely upon fossil fuels for the vast majority of commercial and military applications. Until these fuels are depleted or abandoned, burning them will continue to jeopardize air quality and provoke increased regulation. With those challenges in mind, research and development of more efficient and electric propulsion systems will expand. Fuel-cell technology is but one example that addresses such emission and resource challenges, and others, including negligible acoustic emissions and the potential to leverage current infrastructure models. For now, these technologies are consigned to smaller aircraft applications, but are expected to mature toward use in larger aircraft. Additionally, measures such as electric/conventional hybrid configurations will ultimately increase efficiencies and knowledge of electric systems while minimizing industrial costs.

A key topic of many technical discussions has been the development of alternative fuels to power the compression ignition engine. Reasons for this include the desire to reduce the dependency on petroleum-based fuel and, at the same time, to reduce the particulate matter (PM) and NOx emissions. Also, there has been interest generated in the diesel engine because of the reduction in greenhouse gases that has been proposed during the 2008-2012 time frame in Europe and the regulations that affect diesel engines in the United States.

This compendium presents the most complete design and engineering story available anywhere about this groundbreaking new vehicle. It also introduces you to the engineering team and how they made the world’s first production extended-range electric vehicle a reality. Combining articles from SAE International’s Vehicle Electrification and Automotive Engineering International magazines, new SAE technical papers, and all-new content, this full-color book is the only one of its kind that lifts the veil on how the GM team and key supplier partners met the difficult engineering challenges faced in developing the Volt. Topics include the Volt’s systems, components, and model-based design; a behind-the-wheel look at a Volt prototype; and how the Volt’s engineering team used OnStar to collect test drive data from preproduction Volt vehicles.

Increasingly, travelers are turning to shared mobility and enabling technologies (i.e., smartphone apps) to meet their mobility needs. A consequence of the ever-growing and ever-evolving landscape of shared mobility is the lack of standardized terms and definitions. The shared and digital mobility industry is challenged with discrepancies in use and definition of terms, which often create ambiguity and confusion for policymakers, regulatory agencies, and the broader public. In recognition of this challenge, the SAE Shared and Digital Mobility Committee embarked on the task of developing J3163™ – Taxonomy and Definitions for Terms Related to Shared Mobility and Enabling Technologies. This white paper provides an overview of the rationale, scope, key discussions held in the development of J3163TM, as well as guidance on how to use J3163TM.

The aerospace ecosystem is a complex system of systems comprising of many stakeholders in exchanging technical, design, development, certification, operational, and maintenance data across the different lifecycle stages of an aircraft from concept, engineering, manufacturing, operations, and maintenance to its disposal. Many standards have been developed to standardize and improve the effectiveness, efficiency, and security of the data transfer processes in the aerospace ecosystem. There are still challenges in data transfer due to the lack of standards in certain areas and lack of awareness and implementation of some standards. G-31 standards committee of SAE International has conducted a study on the available digital data standards in aircraft asset life cycle to understand the current and future landscapes of the needed digital data standards and identify gaps. This technical paper presents the study conducted by the G-31 technical committee.

Industry standards are key enablers in helping businesses around the meet regulatory requirements, keep costs down, gain market access, and instill consumer confidence. SAE International, a standards development organization (SDO) critical to the transportation industry, works in partnership with industry to develop and distribute standards important in automotive and aerospace product development, product performance, and quality management. Historically, industry standards were formatted with the intention of being distributed in print. This changed with the evolution of new electronic formats, and now most standards are available in PDF or EPUB. While progressive at the time, these formats are now proving inadequate due their optimization for readability by the human eye versus consumption by electronic endpoints.

Ride along as three children take a spin in a self-driving car and share their thoughts at the SAE Demo Days at Babcock Ranch.

In 1990 in the USA, Section 206 of the Clean Air Act ushered in a new era in passenger car and light truck service and maintenance. Ensuing requirements led to introduction of sophisticated vehicle on-board diagnostic systems. These systems demand the increasing sophistication of service providers. The amount of service information has expanded exponentially. The sophistication of the tools needed to diagnose and repair vehicles has become increasingly complex. To meet the needs of today's service professionals, new systems had to be developed. The convergence of regulations, vehicle complexity, tool capabilities and the growing volume of service information required the vehicle producers and service communities to implement more efficient information delivery systems.

To date, the universal metric for road safety has been historical crash data, specifically, crash frequency and severity, which are direct measures of safety. However, there are well-recognized shortcomings of the crash-based approach; its greatest drawback being that it is reactive and requires long observational periods. Surrogate measures of safety, which encompass measures of safety that do not rely on crash data, have been proposed as a proactive approach to road safety analysis. This white paper provides an overview of the concept and evolution of surrogate measures of safety, as well as the emerging and future methods and measures. This is followed by the identification of the standards needs in this discipline as well as the scope of SAE’s Surrogate Measures of Safety Committee.
