Delphi Presents the Future of Automotive Technology at SAE 2004
TROY, Mich., March 8 -- Delphi Corp. will help lead the discussion on automotive safety, propulsion and lean product design at the upcoming Society of Automotive Engineers (SAE) 2004 World Congress to be held March 8-10 at Detroit's Cobo Center.
Included in Delphi's participation is Delphi Chairman, CEO, and President, J.T. Battenberg III, who will give the keynote address on high performance vehicles. In addition, Delphi will have several executive panel speakers, present 38 technical papers on important industry issues and issue a book on vehicle safety. A second book on the topic is expected to be issued in the second quarter of 2004.
"Events such as the SAE World Congress offer an opportunity for members of the automotive community to learn from one another, and to provide a forum for sharing ideas, addressing challenges and finding solutions," said Battenberg. "The presentation of technical information and discussion of industry issues is essential for the advancement of automotive engineering and will help drive the technologies of the future."

AWARDS
* Delphi research engineer, Mark Sellnau, is receiving the Forest R. McFarland Award, granted by the SAE Engineering Meetings Board (EMB). The award recognizes outstanding services rendered to EMB and SAE, and specifically acknowledges Sellnau's efforts and leadership in contributions to the Advanced Powerplant Committee.
* Delphi manager of Product Environmental Design, Angelika Coyle, is receiving the John Connor Award from the Sustainable Development Program Office at SAE. The John Connor Award recognizes the accomplishments of an individual to promote the environmental vision of SAE within and outside the Society. It was established to meet the demands of the ever-changing environmental challenges that face manufacturers, suppliers and professionals in the transportation industry.
BOOKS
This year, Delphi employees will be editing two books on vehicle safety through SAE:
* "Occupant and Vehicle Responses in Rollovers" by Chantal Parenteau with David Viano from ProBiomechanics; This book examines relevant conditions for field rollovers, vehicle responses, and occupant kinematics in the vehicle and includes over 60 technical documents covering 15 years of rollover crash safety, including field crash statistics, pre- and rollover dynamics, test procedures and dummy responses.
* Later this year, "Automotive Active Safety Systems" will be issued with an introduction by Jean Botti. This compilation of technical papers written by noted experts in the field of automotive safety examines recent developments in chassis technology that enhance the driver's ability to avoid crashes altogether. It reviews currently available stability control technology and how it is being extended to help keep the driver in control. The book also explores how chassis technologies are incorporated into an integrated safety system that helps protect occupants and helps avoid crashes.
TECHNICAL PAPERS
Among the 38 Delphi technical papers being presented at the SAE World Congress, the following are expected to draw especially high levels of interest from the conference:
Detection of vehicle rollover (#2004-01-1757)
This paper proposes an approach for detecting impending rollover. The method includes an algorithm for estimating roll angle and roll rate of vehicle body with respect to the road using lateral acceleration and roll rate sensors. Methods of determining roll angle from sensors are described and their advantages and disadvantages discussed. The proposed model-based roll angle estimation algorithm is described, followed by the introduction of the roll over index. Test results are also discussed.
Emission System Optimization to Help Meet Future European Legislation (#2004-01-0138)
To help comply with reduced European emissions targets, a significant effort was required to minimize light-off time and to improve steady state performance for the pollutants HC and NOx. This paper covers the main challenges and technical solutions. Among them are substantial catalyst improvements needed to accommodate the progressively more severe agings related to high-speed driving conditions in Europe, and the close-coupled location of the catalyst, with the introduction of the converter welded directly to the exhaust manifold. Vehicles in the field have shown that only a systems approach, including optimized exhaust manifold and canning designs, robust engine calibration strategies and specifically developed washcoats, can lead to effective emissions technologies. This paper discusses the major steps that need to be taken to help meet future European emissions targets and minimize cost or optimize packaging.
Simulation-Based Engine Calibration: Tools, Techniques and Applications (#2004-01-1264)
New simulation tools and procedures have been developed by Delphi to rapidly generate optimized calibration maps. The objective of this work is to reduce calibration effort while fully realizing the potential benefit from advanced engine technology. The procedure utilizes GT Power engine simulation software and engine models validated through limited dynamometer testing. This paper describes the simulation tools and procedures, and presents calibration results for a modern V6 engine equipped with a two-step VVA and intake cam phasing. Preferred two-step switching schedules and cam phaser position maps are presented.
Potential Applications of R-152a Refrigerant in Vehicle Climate Control: Part II (#2004-01-0918)
Worldwide concern over the global warming impact of HFC-134a has presented the automotive industry with the pressing challenge of searching for suitable alternative refrigerant(s). HFC-152a, referred to as R-152a in the air conditioning and refrigeration industry, is a potential alternative because of its significantly lower global warming potential relative to R-134a and its chemical and thermodynamic similarity to R-134a. This similarity would allow the conversion to R-152a to occur at low cost with little capital investment. This paper is a continuation of the work on the potential applications of R-152a presented at the 2003 Vehicle Thermal Management Systems Conference (VTMS6). It documents continuing progress in applying R-152a to vehicle climate control systems. The paper compares R-152a cooling performance and energy performance to comparable R-134a system designs, including direct and indirect expansion systems. Significant findings include the improved cooling performance of R-152a over that of R-134a while, at the same time, using less energy than R-134a. Also presented are means to assure safe system operation with R-152a refrigerant.
A Supervisory Control to Manage Brakes and Four-Wheel-Steer Systems (#2004-01-1059)
The coordination of multiple chassis systems such as QUADRASTEER(TM) Four Wheel Steering (4WS) and Brake-Based Vehicle Stability Enhancement (VSE) is optimized with a supervisory control structure. Coordinated control provides a means to optimize the overall performance by appropriately distributing workload to each system and taking advantage of the unique strengths of each system. The result is an improvement in vehicle stability and driver workload and a reduction in vehicle-handling compromises that typically hinder each standalone system. Vehicle test results prove the viability of the concept.
