Active Safety and the Mobility Industry

2011-04-11
Safety is a key element in new vehicle design and active safety, together with driver distraction prevention, has become one of the most talked about issues in the mobility industry. This book features 20 SAE technical papers, originally published in 2009 and 2010, which showcase how the mobility industry is considering all aspects of safety in designing and producing safer vehicles. These papers were selected by SAE International's 2010 President Dr. Andrew Brown Jr., Executive Director and Chief Technologist for Delphi Corporation. The contents of this book explore a variety of safety issues in the areas of market and consumer preferences; driver assistance and modeling; active safety system, crash sensing and sensor fusion; communications; and road safety. The publication also includes a number of articles authored by renowned experts in the field of active safety.

Engine Stop Position Estimation

2012-04-16
2012-01-0720
This paper describes a method to estimate the engine stop position using any production style crank position sensor, while accounting for possible engine rock-back. The approach is based on modeling the engine speed state, achieving robustness and ease of calibration by adapting the rubbing friction model component during the first part of engine coast-down, followed by open-loop modeling when the engine speed has dropped below the sensor signal validity threshold.

Finite Element Simulation Study of a Frontal Driver Airbag Deployment for Out-Of-Position Situations

2003-10-27
2003-22-0011
As more and more active restraint devices are added by vehicle manufacturers for occupant protection, the history of driver frontal airbags illustrates that the design performance of such devices for in-position (IP) occupants often have to be limited in order to reduce their aggressiveness for out-of-position (OOP) situations. As of today, a limited number of publications dealing with FE simulation of airbag deployment for OOP are available. The objective of our study was to evaluate the feasibility of airbag deployment simulations based on an extensive set of well-defined physical test matrix. A driver frontal airbag was chosen (European mid-size car sample) for this study. It was deployed against a force plate (14 tests in a total of 6 configurations), and used with Hybrid III 50th percentile dummy (HIII) in OOP tests (6 tests, 4 configurations). Special attention was paid to control the boundary conditions used in experiments in order to improve the modelling process.

Nanotechnology Applications in Future Automobiles

2010-04-12
2010-01-1149
It is rare for a single technology to have the power to dramatically influence almost every major industry in the world. Nanotechnology falls into this category and offers fundamentally new capabilities to architect a broad array of novel materials, composites and structures on a molecular scale. This technology has the potential to drastically re-define the methods used for developing lighter, stronger, and high-performance structures and processes with unique and non-traditional properties. This paper focuses on some of the automotive applications for nanotechnology and showcases a few of them that are believed to have the highest probability of success in this highly competitive industry. No discussion of nanotechnology is complete without touching upon its health and environmental implications.

Risk Reducing Product and Process Design During New Product Development

2010-04-12
2010-01-0391
In today's dynamic automotive environment, reducing the lead-time to introduce new product technologies to the market place can be a key competitive advantage. Employing proactive risk reduction techniques to define key product and process relationships is essential to enhance the production worthiness of a design while it is still in the advanced development phase of the program. This paper describes how Delphi Powertrain Systems applied the Shainin proactive risk reduction methodology in advanced product development to focus resources on understanding and mitigating the risk associated with the development of a new Delphi ammonia sensor. Organizational and technical strategies to accelerate profound knowledge capture, along with corresponding test results, are presented and discussed.
