Abstract The automotive industry is racing to introduce some degree of hybridization into their product ranges. Since the term “hybrid vehicle” can cover a wide range of differing technologies and drivetrain topologies, this has led to a large amount of vehicles that call themselves “hybrid”. This poses an interesting challenge for marketers to differentiate these vehicles from the incumbents. However, it is not just the marketers who are faced with challenges, the developers of such hybrid drivetrains are faced with a rise in technical complexity due to the wide range of operating modes hybridization introduces. As propulsive torque is being generated in more than one place in a hybrid vehicle, the transitions from conventional drive to electrically supported drive bring with them complex aspects of multi-dimensional system control. The challenge is to be able to implement hybrid technology in an existing drivetrain, while adapting the existing components as required.

LEDs are now acknowledged as the mainstream standard light source of what might reasonably be called ‘the future already in progress’. Their small size, powerful light emission, extreme reliability, low energy requirement and long lifespan mean that LEDs continue to make quick inroads in automotive sectors governed by cost and performance demands alike. Indeed, since the last edition of this report was published in 2010, the sector has continued to witness a blistering rate of innovation, and LEDs have now broken every automotive application barrier. Nevertheless, there are other light source technologies that have sprung from LED research and development, and some are poised to supplement – or even, in certain applications, supplant them.

This book tells the improbable stories of Franklin W. Olin College of Engineering and the iFoundry incubator at the University of Illinois. That either one survived is story enough, but what they found out together changes the course of education transformation forever: • How trust is key to unleashing young, courageous engineers. • How engineers need to move from a narrow technical education to one that actively engages six minds. • How emotion and culture-not content, curriculum & pedagogy-are the crucial elements of change. • How all stakeholders can collaborate to disrupt the status quo. A Whole New Engineer is a book that seriously looks at the coming revolution in engineering.

This master report summarizing and forecasting every sector of the EV industry remains unique. It adds new sectors as they become substantial, the latest being car-like micro-EVs homologated as quadricycles in Europe. Many profitable niches are emerging just as the largest major sectors are changing in importance; the industrial and commercial sector is now bigger and much more profitable than e-cars, and is set to remain so for at least eight more years. All components are changing with supercapacitors sometimes replacing or partly replacing batteries and also new types of battery, energy harvesting, power electronics and structure powering growth. Disruptive change is now the norm and the fruits of all this are truly spectacular; including such things as the Marian fast- surface boat that acts as a submarine when necessary, the fixed-wing plane that will stay aloft for five years on sunshine and the flying jet ski.

Rear underrun protection device is crucial for rear impact and rear under-running of the passenger vehicles to the heavy duty trucks. Rear underrun protection device design should obey the safety regulative rules and successfully pass several test conditions. The objective and scope of this paper is the constrained optimization of the design of a rear underrun protection device (RUPD) beam of heavy duty trucks for impact loading using correlated CAE and test methodologies. In order to minimize the design iteration phase of the heavy duty truck RUPD, an effective, real-life testing correlated, finite element model have been constructed via RADIOSS software. Later on, Pareto Optimization has been applied to the finite element model, by constructing designed experiments. The best solution has been selected in terms of cost, manufacturing and performance. Finally, real-life verification testing has been applied for the correlation of the optimum solution.

Abstract Automotive climate control systems are evolving at a rapid pace to meet the overall vehicle requirements and the user expectations for comfort and convenience. This poses a challenge in the product development life cycle of multi-platform vehicle systems with respect to development time and optimal performance in the Heating, Ventilation and Air Conditioning (HVAC) system. This paper proposes rapid HVAC plant model design and development using simplified one-dimensional (1D) simulation models for fast simulations. The specific accuracy limitations of such a simplified model are overcome using limited three-dimensional computational fluid dynamics (3D CFD) modelling. User-level control strategy is developed in an integrated simulation environment that includes a reference 1D model and a control algorithm simulator. The simulation data is used to study and analyse the temperature and airflow distribution in the system.

Abstract Using a Model-based approach to the embedded software development process contributed significantly in reducing the development time while also supporting a high quality level of the software code implementation. However, based on our experience with CNH Industrial application scenarios, involving multiple suppliers from vehicle ECU to the engine ECU, it only addressed the need of the implementation phase without any consistent influence in other software development life-cycle phases such as requirements and specification. Mandatory functional safety requirements, new complex functionalities, and reducing time to delivery while maintaining high quality level of software are driving factors in our new software development projects. Ideally the adoption of international standards, as for example the ISO 12007, and the safety standards, as the ISO 26262, ISO 25119 and ISO 13849, should represent a consistent guide to develop software.

In order to satisfy China IV emissions regulations, a unique design concept was proposed with injector closely coupled with Selective Catalytic Reduction (SCR) system outer body. The benefit of this design is significant in cost reduction and installation convenience. One paper was published to describe the vertical inlet layout [1]; this work is the second part describing applications of this concept to horizontal inlet configurations. For horizontal inlet pipe, two mixing pipe designs were proposed to avoid urea deposit and meet EU IV emission regulations. Computational Fluid Dynamics (CFD) technique was used to evaluate two design concepts; experiments were performed to validate both designs. CFD computations and experiments give the same direction on ranking of the two decomposition tubes. With the straight decomposition pipe design and unique perforated baffle design, no urea deposits were found; in addition, the emission level satisfied EU IV regulations.

Cost reduction in the automotive industry becomes a widely-adopted operational strategy not only for Original Equipment Manufacturers (OEMs) that take cost leader generic corporation strategy, but also for many OEMs that take differentiation generic corporation strategy. Since differentiation generic strategy requires an organization to provide a product or service above the industry average level, a premium is typically included in the tag price for those products or services. Cost reduction measures could increase risks for the organizations that pursue differentiation strategy. Although manufacturers in the automotive industry dramatically improved production efficiency in past ten years, they are still facing the pressure of cost control. The big challenge in cost control for automakers and suppliers is increasing prices of raw materials, energy and labor costs. These costs create constraints for the traditional economic expansion model.

The Braking System is the most crucial part of the racing vehicle. There is no doubt, that if only one minority failure in the braking system took place, this would be more than enough reason to cause the racing team disqualification from the competition. Time is the main and the most important criteria for any racing competition; on the other hand the formula student “FS UK SAE” competition care the most about developing the automotive engineering sense in the students by putting them under strict rules normally taken from the original version “formula 1” to encourage their creativity to reach the optimum performance under these strict rules. One of the most important rules is “No Braking by wire”, and the obvious consequences are more stopping distance and time. Braking distance is a critical facture in achieving racing success in a competitive domain.

Data is information (e.g., concepts, thoughts, and opinions) that have been recorded in a form that is convenient to move or process. Data may represent tables of values of various types (numbers, characters, and so on). Data can also take more complex forms such as engineering drawings and other documents, software, pictures, maps, sound, and animation.

Data management, from the perspective of this standard, consists of the disciplined processes and systems that plan for, acquire, and provide stewardship for product and product-related business data, consistent with requirements, throughout the product and data life cycles. Thus, this standard primarily addresses product data and the business data required for collaboration from the team level or extended through the trading partner level during product acquisition and sustainment. It is recognized, however, that the principles described in this standard also have broader application to business data and operational data generally.

Abstract Counterfeit items can be viewed as the by-product of a supply chain which has been compromised. While many industries are impacted, certain types of products can mean the difference between life and death. Electronics are of special interest, however, mechanical parts can also have dire consequences. The point is that the counterfeiting community is very diverse. The business model is fluid and unrestricted. Electronics today…hardware tomorrow. All of this leads to the need for an authentication platform that is agnostic to product. Most supply chains would benefit from a technical way to have assurance of authenticity - a benefit that could be shared by all.

Abstract Since 2000, avionics is facing several changes, mostly driven by technological improvements in the electronics industry and innovation requirements from aircraft manufacturers. First, it has progressively lost its technological leadership over innovation processes. Second, the explosion of the electronics consumer industry has contributed to shorten even more its technology life cycles, and promoted the use of COTS. Third, the increasing complexity of avionics systems, which integrate more and more functions, have encouraged new players to enter the market. The aim of this article is to analyze how technological changes can affect the competitiveness of avionics firms. We refer to criticality levels as a determinant of the market competitiveness. Certification processes and costs could stop new comers to bring innovations from the consumer electronics industry and protects traditional players.

Abstract To make the development of complex aircraft systems manageable and economical, tests must be performed as early as possible in the development process. The test goals are already set in advance before the first hardware for the ECUs exists, to be able to make statements about the system functions or possible malfunctions. This paper describes the requirements on and solutions for test systems for ECUs that arise from these goals. It especially focuses on how a seamless workflow and consistent use of test systems and necessary software tools can be achieved, from the virtual test of ECUs, which exist only as models, up to the test of real hardware. This will be shown in connection with a scalable, fully software-configurable hardware-in-the-loop (HIL) technology. The paper also covers the seamless use of software tools that are required for HIL testing throughout the different test phases, enabling the reuse of work products throughout the test phases.

Abstract In the last few years, we have seen a tremendous increase in the rise in product complexity due to advances in technology and aircraft system functionality enhancement. The Model-based Design (MBD) process has helped manage the complexity of these systems while making product development faster by bringing more effective tools and methods to the entire process. Developing software using MBD has required extensive, sophisticated tool-chains that allow for efficient rapid controls prototyping, automatic code generation, and advanced validation and verification techniques using model-in-the-loop (MIL), software-in-the-loop (SIL), and hardware-in-the-loop (HIL) for both component testing and integration testing. However, the MBD process leads to generation of large volumes of data artifacts and work-products throughout the V-Cycle.

Abstract Within the Russian aviation industry the necessary level of reliability risks related to the failures of aircraft mechanical parts and systems vital to the safety of flight is assured via the system of activities aimed at influencing the parameters of critical parts (CP). The goal of the system is to provide a relationship between activities aimed at prevention of dangerous failures at all phases of airplane life cycle. The system operation is regulated by the normative documents and by controlling their observance. Normative documents containing requirements and recommendations were developed about 15 years ago based on the industry experience and traditions and taking into account the requirements of AS9100 series of international standards [2] wherever possible. The documents were developed taking into account typical safety management errors outlined in [1].

Aerospace suppliers face the daunting task of constantly improving time-to-market, reducing cost of quality and turning compliance into a competitive advantage. Managing to these constraints while staying profitable is a challenge faced by the entire aerospace supply chain face today. The intent of this presentation is to share five lessons learned on how aerospace suppliers can optimize for these three constraints while growing their businesses. The first is electronically enabling traceability both within a multi-tier supply chains and throughout suppliers. Automating traceability at the shop floor improves quality management and accelerates compliance. Specific methodologies and metrics used to accomplish this will be provided. Second, lessons learned from implementing Manufacturing Execution Systems (MES) showing how shop floor visibility has a direct effect on supplier performance is illustrated with case studies and metrics.
