Fuel Efficiency: Racing Toward CAFE 2025 (DVD)

2015-04-15
"Spotlight on Design" features video interviews and case study segments, focusing on the latest technology breakthroughs. Viewers are virtually taken to labs and research centers to learn how design engineers are enhancing product performance/reliability, reducing cost, improving quality, safety or environmental impact, and achieving regulatory compliance. Fuel efficiency, or simply put, how to get more mileage out of the same amount of fuel has become one of the main goals to be achieved by new automotive technologies in the future, thanks in part to new government regulations. In the episode "Fuel Efficiency: Racing toward CAFE 2025" (21:24) AVL engineers show simulation and testing being used to design more fuel efficient vehicles, including the equipment that actually analyzes fuel economy.

Consumer Behavior and Risk Aversion

2011-11-04
Nissan has released our original HEV system in Japan on November 2010, and will release it in US market on March 2011. The 1 motor 2 clutch parallel type using conventional 7 speed automatic transmission has been employed without torque converter and with a manganese cathode and laminated type Li-ion Battery. This system is well recognized its higher efficiency but lower weight and cost, however, has never realized due to technical difficulties of smoothness. At this session, performance achievements and hinged breakthrough technologies will be presented. Presenter Tetsuya Takahashi, Nissan Motor Co., Ltd.

General Motors Hybrid Systems and New e-Assist Powertrain

2011-11-18
Hybrid systems have been available for several years now, and offer customers a decrease in fuel consumption and CO2 emissions at an incremental price. Hybrids, in some cases, have offered improved other customer benefits such as reduced noise, vibration and harshness or better acceleration and the satisfaction of increased societal benefit. Sometimes the vehicle utility is compromised by the volume dedicated to energy storage systems. Several hybrid architecture arrangements exist in the market, and offer various levels of hybrid feature. But considering acquisition cost and operating expense, most hybrid vehicles have not offered a direct total cost advantage when compared to non-hybrids. GM's new e-Assist system is highly integrated with the engine and transmission functionality, and takes advantage of the highest value fuel economy enablers available with light electrification.

Cooling Airflow System Modeling in CFD Using Assumption of Stationary Flow

2011-11-29
Battery Electric Vehicles and Extended Range Electric Vehicles, like the Chevrolet Volt, can use electrical energy from the Grid to meet the majority of a driver�s transportation needs. This has the positive societal effects of displace petroleum consumption and associated pollutants from combustion on a well to wheels basis, as well as reduced energy costs for the driver. CO2 may also be lower, but this depends upon the nature of the grid energy generation. There is a mix of sources � coal-fired, gas -fired, nuclear or renewables, like hydro, solar, wind or biomass for grid electrical energy. This mix changes by region, and also on the weather and time of day. By monitoring the grid mix and communicating it to drivers (or to their vehicles) in real-time, electrically driven vehicles may be recharged to take advantage of the lowest CO2, and potentially lower cost charging opportunities.

Impact of Model-Based Lithium-Ion Battery Control Strategy on Battery Sizing and Fuel Economy in Heavy-Duty HEVs

2011-12-05
Software usability is a quality attribute defined as ?the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specific context of use? (ISO 9241, 1998), usability is also referred to as ?quality in use? (ISO 14598, 1999). Presenter Anabell Beltran, Stoneridge Electronics North America

New Energy Vehicle (NEV) Progress in China

2012-03-29
Vehicle electrification is shaping the future of automotive mobility in terms of automotive power and propulsion. The market for New Energy Vehicles (HEV/PHEV/REEV/EV) as well as clean vehicle technologies is expected to grow steadily driven by government regulations mandating increased fuel economy and lower emissions. The fastest growth in this market will be in Asia Pacific, most notably China. The Chinese government has made its intentions clear on how important it considers the development and consumer purchase of hybrid and electric vehicles. The mandate is that by year 2012, vehicle manufacturers produce at least 500,000 units (or 5%) per year of their total output as hybrid and/or electric. All Chinese vehicle manufacturers must have at least one HEV or EV model in the market by the same year. Thus far China has invested over US$3.5 billion to stimulate the production of NEVs and the necessary infrastructure to support them.

Toyota's Comprehensive Environmental Technology: Providing Choices for Sustainable Mobility

2012-03-31
Toyota is committed to the development of advanced powertrains to help address concerns with future oil supplies, the impacts of increased carbon dioxide emissions, and air pollution. Towards that end Toyota is planning to bring to market in 2012 a plug-in hybrid vehicle, a short range electric vehicle, a long range electric vehicle and in the 2015 timeframe hydrogen powered fuel cell vehicle. This presentation will focus on our electric vehicle plans and the challenges with bringing electric vehicle to the market. From the 2010 Alt Fuels Study, Toyota has identified that two key barriers for EV adoption are the times to charge the vehicle, and electricity cost. The study finds that the current infrastructure could be sufficient for most driving needs but EV drivers will still need to alter their driving habits slightly.

Beyond MPG: Characterizing and Conveying the Efficiency of Advanced Plug-In Vehicles 

2011-11-08
Research in plug in vehicles (PHEV and BEV) has of course been ongoing for decades, however now that these vehicles are finally being produced for a mass market an intense focus over the last few years has been given to proper evaluation techniques and standard information to effectively convey efficiency information to potential consumers. The first challenge is the development of suitable test procedures. Thanks to many contributions from SAE members, these test procedures have been developed for PHEVs (SAE J1711 now available) and are under development for BEVs (SAE J1634 available later this year). A bigger challenge, however, is taking the outputs of these test results and dealing with the issue of off-board electrical energy consumption in the context of decades-long consumer understanding of MPG as the chief figure of merit for vehicle efficiency.

Legislation & International Trends Effecting Development of Hybrids

2011-11-08
One of the major trends in the last decade has been the increasing hybridization in the vehicle population. The degree of hybridization varies from mild to strong including those capable of limited, all electric range. Some experts predict that hybridization will spread to 100% of vehicles in the next decade. In addition, the recent introduction of plug-in hybrid electric vehicles has added a significant new dimension to the hybridization scene. This talk will focus on the global trends in hybrid sales, including plug-in hybrids, and will try to identify the various mechanisms, whether legislation or incentives, which are driving this increase in sales. Data will be gathered from various countries in the world including China, Europe, Japan and the United States. The potential for different mechanisms in play in the developed world compared to the developing world will be examined.

Automated Diagnostics System Performance Assessment

2012-01-30
Powertrain Systems development is facing unprecedented challenges driven by the convergence of many factors: increasing government regulations for tailpipe emissions, diagnostics and fuel economy, increased competition, shorter development cycles, and tighter program budgets. Using telematics and information technology to automate the evaluation of a system�s robustness enables engineers to focus their time on problem areas during their normal development process and launch with quality. This presentation will use real world examples to detail how this methodology was jointly applied by Control-Tec and Ford Motor Company to identify and improve the system performance of Ford�s Air-Fuel Imbalance Monitor before production.
