Today’s designers seek to integrate sensor technology, electronic and mechatronic systems in progressively introducing Electric Power Steering (EPS) systems. However, from a customer perspective on the one hand steering is one of the most visible or tangible aspects of vehicle quality in driving when quality is compromised (through NVH issues), while on the other hand, when executed well, a steering system is all but transparent to the driver. To a number of commentators and OEMs ‘steering feel’ has become termed as contributing to the essential ‘DNA” of the vehicle, and it is therefore an essential aspect of competitive advantage or position. This report examines steering feel and the increasing effect of vehicle electrification, and looks at steering and chassis performance. It also considers the key drivers including fuel efficiency and CO2 emissions, steering design, materials considerations and the packaging dilemma.

Abstract Tire rolling resistance is one of tire performance indicator that represents a force needed to maintain the constant rolling of a tire. There are quite few methods and standards to measure tire rolling resistance, such as ISO-28585, ISO-18164, SAE-J1269, SAE-J2452, …. These tests have been used by tire companies, vehicle manufactures, and government agencies to evaluate tire rolling resistance performance. SAE-J1269 and SAE-J2452 are two popularly used multi-condition rolling resistance tests for passenger and light truck tires. Examining the test conditions and procedures of these two test standards showed that some key procedures and conditions from both standards are similar although there are many difference as well. The study presented here is to analyze test results from both tests and their correlation under certain conditions. If the correlation exists, one test may provide test results for both test conditions, therefore, test efficiency can be improved.
The Role of Accurate Simulation of Real World Conditions and ART/ADT Technology for Accurate Efficiency Predicting of the Product/Process
Abstract This paper will discuss how accurate simulation of the real world conditions and ART/ADT (accelerated reliability/durability testing) technology is influencing accurate efficiency predicting as a final goal of product/process design, manufacturing, and development. The paper begins with the overview of current approaches of predicting the efficiency for a complete product and its components with an examples of life cycle costs (LCC), empirical reliability, physics-based reliability, their benefits and risks. It includes also the history of reliability prediction. As a result of the overview, it will be conclude that one cannot ensure that predicting results will not be misinterpreted or misapplied, even though all assumptions and rationale have been meticulously documented and clearly stated.
Abstract The Sarbanes-Oxley Act created new standards for corporate accountability pertaining to all publicly-owned and traded firms. It holds top executives accountable for the accuracy of all financial data and statements, including reported tangible assets. It requires existence of auditable internal accounting control measures and specifies adherence to new internal controls and procedures designed to ensure the validity of their financial records and physical assets. The Act presents a challenge to every manufacturing firm to have a low-cost system implemented that can produce an exact physical-asset location, existence, verification and accounting on demand. Clearly, such low-cost solutions for enterprise-wide compliance would also provide verifiable and reliable data for corporate property tax, loan collateral, and audit requirements.
Abstract This paper examines the pace at which manufacturers have added certain powertrain technology into new vehicles from model year 1975 to the present. Based on data from the EPA's Light-Duty Automotive Technology, Carbon Dioxide Emissions, and Fuel Economy Trends database , the analysis will focus on several key technologies that have either reached a high level of penetration in light duty vehicles, or whose use in the new vehicle fleet has been growing in recent years. The findings indicate that individual manufacturers have, at times, implemented new technology across major portions of their new vehicle offerings in only a few model years. This is an important clarification to prior EPA analysis that indicated much longer adoption times for the industry as a whole.
Convolution of Engineering Methods (TRIZ, FMEA, Robust Engineering) to Creatively Develop New Technologies
Abstract Many high risks of failure in developing and applying new technologies exist in the recent automotive industry because of big volume of selling cars in a global market. Several recalls cost companies more than $ 100 million per problem. New technologies always have uncertainty in performing intended functions at various given conditions despite the fact that engineers do their best to develop technologies to meet all the requirements. Uncertainty of new technologies put companies into danger of failing in their business. Therefore, many companies tend to take interest in reducing risks from the uncertainty in technologies, but the increasing complexity of modern automotive technologies make it difficult to develop complete technologies. A new engineering methodology called SPEED Engineering was introduced to reduce the risks of new technology applications and to facilitate engineers to conceive innovative ideas dominating the market in the future.

It reduces lead time, cuts cost, and improves quality. In order to be competitive, enterprises in western countries widely use lean manufacturing and logistics principles in automotive industries, especially for engine manufacturing system due to its high contents of assembly work. However, in China, lean logistics and its applications are fairly new to many companies. This article analyzes the current status of lean logistics in engine manufacturing in China, summarizes lean logistics principles, put forwards application of lean logistics principles based on a real case study of a new manufacturing system planning.
Abstract The Rowan University Mechanical Engineering program is studying the use of a long-term (five semester) design project on student learning and concept retention. The project, a bench-scale hybrid electric powertrain system, is designed, analyzed and fabricated by students in five modules, starting in their sophomore year and culminating in their final semester as seniors (see prior ASEE publication ). This complex project has been selected in order to integrate the core mechanical engineering courses: Mechanical Design, Thermodynamics, System Dynamics and Control, and Fluid Mechanics. A bench-scale hybrid-electric vehicle powertrain has sufficient complexity to involve all Mechanical Engineering disciplines and the simplicity to be built by students over the course of five semesters. In addition, hybrid-electric technology is at the cutting-edge of automotive technology, and has been found to hold a special fascination for most mechanical engineering students.
Abstract There has probably never been such a demand for professionally qualified engineers, and yet both the number and diversity of people entering the profession continue to decline. Worldwide, there are very many initiatives - some generally encouraging interest in the profession, and others targeting specific audiences. The reports speak of local success, but the overall picture remains discouraging. In this paper we focus on the “pipeline” from primary education through to the transition from graduate engineer into an experienced member of engineering staff. We have based the discussion on both the presentations and comments made during a panel discussion held at the 2013 SAE International Congress. The paper is intended as a summary of the points raised during that discussion and, we hope proves to be starting point for further investigation and analysis. Of particular note is the sheer diversity of initiatives, and the pressing need for role models and mentoring.
Methodology to Identify and Minimize the Risks Associated with Future Design changes in the Transmission of Wheel-Loader
Abstract The aim of the paper is to describe how Volvo Construction Equipment uses a virtual product development process to analyze potential risks, find root causes and optimize future product development. A model based method is used to analyze a potential risk in the design of Wheel Loader transmissions. The risk was recognized from failure mode and effect analysis (FMEA), and a simulation model using AMESim modeling tool was developed to analyze the behavior of the new design. Together with test rig result, it is proved that the model based method gives a considerably accurate prediction of the system behavior. By using the model based approach, lead time for development process is reduced and important feedbacks from simulation model are obtained on early stage of the development. This paper further presents the use of the simulation model as a tool to predict the potential risks in the extreme operating conditions, which are difficult to test on the vehicle test bench.
