Design reviews are required for ISO 9001:2000 compliance and compatible automotive and aerospace specifications. They are becoming increasingly important in product liability litigation and are accepted as a cost-effective best practice and an effective application of knowledge management, valuable for accelerating the maturity of new products. This seminar describes how formal design reviews can improve products by uncovering potential problems before they are discovered at a later stage of development or application, when the costs of correction are much higher.

In this talk, we will explore some conceptual use cases of Augmented Reality in manufacturing and other industrial applications, and the technology gaps that currently exist preventing them from turning into a reality. We’ll elaborate on this theme by looking at how current marketing for this technology has led to over-inflated expectations for what exists today, and the effect that is having on its perception outside of the community. To continue we will look at work being done both in industry and academia to address these technology gaps and how we are moving closer to meeting those expectations, and finally we’ll uncover the huge benefits in manufacturing operations once we are successful.

The intersection is happening. The intersection between the vehicle and the product world is finally happening. And one quick walk on this year’s CES at Las Vegas and NAIAS at Detroit will ascertain the right confluence of the same. Albeit the apparent differences in the lead-time of the development processes, there is a lot to be cross-pollinated between these two not-so-distinct ecosystems. Because fundamental core sits the end user – the human being. And prevalent school of thoughts in both the disciplines are rightfully acknowledging the human centricity needed to plan for and design “objects” and “services” as an seamless offering. Gone are the days to just push metal or cheap plastic artifacts to the consumer, as that definition of consumer itself is changing.

This paper presents an overview of a four-year project on integrated computational materials engineering (ICME) for third generation advanced high-strength steels (3GAHSS) development. Following a brief look at ICME as an emerging discipline within the Materials Genome Initiative, technical tasks in the ICME project will be discussed. Specific focus of the individual tasks is on multi-scale, microstructure-based material model development using state-of-the-art computational and experimental techniques, forming, assembly, design optimization, integration and technical cost modeling. The integrated approach is illustrated using a 980 grade transformation induced plasticity (TRIP) steel with a two-step quenching and partitioning (Q&P) heat treatment as an example.

We have developed four completely new parts for fuel cell vehicles. They are called separator, stack manifold, ion exchanger, silencer. The separator is a pressed metal plate sandwiched between the MEA(Membrane Electrode Assembly) ,and it has a flow path of hydrogen, air and coolant. The separator we have developed is anode separator. It has hydrogen flow paths on one side, and cooling liquid flow paths on the other side. The pitch of flow paths is very fine, it improve the uniformity of the gas flow and uniformity of the surface pressure on the MEA, therefore, it have contributed to improve the power generation performance. Also since nearly 400 separators are stacked up for one Fuel Cell Stack, it has to be very accurate. We have succeeded in the mass production of the separator by applying a precision press technology. Stack manifold is a component that attaches to the end of one side of the fuel cell stack. It is a component that integrates end plate and pipes.

Upcoming stringent regulations on emissions and fuel efficiency are driving the automotive industry towards light-weight vehicle design. A higher share of carbon fiber composite materials in vehicle structures is expected. Current literature addresses development processes of composite components under a limited scope but the considerations of design parameters used in these studies are inadequate for the realistic development of a full vehicle structure, especially in a resource-constrained development project. In addition, existing vehicle structure design philosophies used for metallic structures cannot be directly ported over for composites design due to the differences in material properties, failure modes and design for manufacturing limitations.

As requirements for protecting the global environment are being heightened on a worldwide scale in recent years, the development of fuel-economy technologies in order to reduce CO2 emissions is an important issue for the automotive industry. Aiming of improving fuel economy, TOYOTA has developed a new belt-type continuously variable transmission (CVT), unit K114, for 2.0-liter class vehicles. The CVT has adopted various technologies fuel economy such as a coaxial 2-discharge port oil pump system, wider ratio coverage, flex lock-up control,and so on. Notably, a start-stop system, which makes the engine stop automatically while the vehicle stopping with “D” range to reduce wasting the energy, is compatible with the CVT with higher quality and lower cost. In addition, the CVT has been also worked on improving quietness by adopting new soundproofing cover and by revising the arrangement of the steel belt elements in order to reduce the vibrator force which generates the belt noise.

Plug-in hybrid electric vehicle (PHEV) is one of the promising solutions for future transportation. Hybrid electric vehicle (HEV) is originally characterized by better fuel economy in comparison with conventional vehicles based on gasoline and diesel engine. However, in recent years, customers are becoming to expect the additional merits for environmentally friendly vehicle such as vehicle acceleration and dynamics. Moreover, electric range is a major concern of PHEV and significantly affects the vehicle architecture including battery capacity, power and vehicle weight. This study aims to build a comprehensive simulation used at the early stage of PHEV development. This simulation enables to design vehicle concept and fundamental architecture with regard to fuel economy, vehicle acceleration and electric range.

The approach of combining highly boosted Ethanol Direct Injected (EDI) engines with extreme downsizing represents a powerful means to reduce CO2 emission at reduced production costs, making it possible to replace high-displacement E0 or E22 engines with smaller highly boosted engines running with bio-fuels such as hydrated ethanol in Brazil (E100) or in North America and Europe (E85). The DI approach is an ideal system for an ethanol engine as the fuel properties enable high compression ratios (CR) in the range of 12 to 13:1, eliminating knock occurrence and generating precise fuel metering. Applied initially to a single turbocharged downsized, down-speeded engine can be obtained a significant decrease in engine friction and a reduction in the exhaust emissions as well a recovery of the power output. This leads to a significant improvement in brake thermal efficiency.

The introduction of new safety critical features using software-intensive systems presents a growing challenge to hazard analysis and requirements development. These systems are rich in feature content and can interact with other vehicle systems in complex ways, making the early development of proper requirements critical. Catching potential problems as early as possible is essential because the cost increases exponentially the longer problems remain undetected. However, in practice these problems are often subtle and can remain undetected until integration, test, production, or even later when the cost of fixing them is the highest. In this paper, a new technique is demonstrated to perform the hazard analysis iteratively in parallel with the development process. This safety-driven design technique is based on Systems-Theoretic Process Analysis (STPA) and is demonstrated in this paper using a realistic Shift-By-Wire design concept.

The framework structure of this Continuously Variable Transmissions (CVT) differs from that of previous CVT. For this CVT, we used the framework structure of our CVT for midsize cars, and changed the pulley shaft support structure and consolidated the arrangement of the hydraulic control system and hydraulic supply unit. To achieve a higher level of both starting acceleration and fuel efficiency in which the CVT is installed, we set the ratio coverage to 6.2, which represents a 14% improvement. We set the Low side ratio to the same as the previous CVT and increased the OD side ratio To ensure that the components of the fundamental framework can be mounted in vehicles with widely varying engine capacities, we designed the components to tolerate torque levels comparable to those of a 1.8 liter engine while reducing their weight by approximately 12%.

Despite the considerable advancements made in the applications of CAE for evaluation of an IC engine, an integrated approach to the design of such engines based on thermo-mechanical considerations appears to be lacking. The usage of heterogeneous tools for thermal, mechanical and vibration analysis in industry decreases the efficiency of the product development process. In an effort to reduce this bottleneck, a unified framework is presented here according to which heat transfer and thermo-mechanical stress analysis of a four-stroke single cylinder diesel engine is carried out in a unified manner with the aid of a multi-physics explicit finite element analysis tool, namely LS-DYNA, with robust contact interfaces leading to realistic representation of engine dynamics.

Abstract Demand for increased functionality in automotive electrical/electronic (E/E) systems is being propelled by both customers and various governmental regulations and requirements. This demand for more capabilities also introduces new challenges for OEMs who are responsible for implementing these functions. Of course, the cost of system development and manufacturing are considerable, but there are challenges beyond cost that the OEM must deal with, such as increased weight, reliability and quality concerns, exponentially-increasing complexity, and the government requirements. From the point of view of the electrical system platform as a whole, it provides the unique role of integrating all the individual E/E systems. When integrated, unanticipated problems can emerge that require design modifications. Often, these are discovered way down the design path, which results in delays in the program that can lead to missed deadlines and costly rework.

The Chevrolet Volt is an electric vehicle with extended-range that is capable of operation on battery power alone, and on engine power after depletion of the battery charge. Since its introduction in 2011, Chevrolet Volts have been driven over half a billion miles: 63% as electric vehicles and 37% in extended range driving. For 2016, GM has developed the secon-generation of the Volt vehicle and “Voltec” propulsion system. The second-generation of Volt electric propulsion system is built on two electric machines; both interior permanent magnet type. While hybrid-electric vehicles are gaining in popularity in hopes of addressing cleaner, energy sustainable technology in transportation, materials sustainability and rare earth dependence mitigation has not been the first priority in the hybrids available on the market today.

Simulation based design optimization has become the common practice in automotive product development. Increasing computer models are developed to simulate various dynamic systems. Before applying these models for product development, model validation needs to be conducted to assess their validity. In model validation, for the purpose of obtaining results successfully, it is vital to select or develop appropriate metrics for specific applications. For dynamic systems, one of the key obstacles of model validation is that most of the responses are functional, such as time history curves. This calls for the development of a metric that can evaluate the differences in terms of phase shift, magnitude and shape, which requires information from both time and frequency domain. And by representing time histories in frequency domain, more intuitive information can be obtained, such as magnitude-frequency and phase-frequency characteristics.

Abstract The paper discusses the benefits of a four stroke engine having one intake and one exhaust rotary valve. The rotary valve has a speed of rotation half the crankshaft and defines an open passage that may permit up to extremely sharp opening or closing and very large gas exchange areas. This design also permits central direct injection and ignition by spark or jets. The dual rotary valve design is applied to a naturally aspirated V-four engine of 1000cc displacement, gasoline, methane or hydrogen fuelled with central direct injection and spark ignition. The engine is modeled by using a 1D engine & gas dynamics simulation software package to assess the potentials of the solution. The novelty in the proposed dual rotary valve system is the combustion chamber of good shape and high compression ratio with central direct injector and spark plug or jet ignition, coupled to the large gas exchange areas of the rotary system.

The underlying theories of, both, control engineering and real-time systems engineering, assume idealized system abstractions that mutually neglect central aspects of the other discipline. Control engineering theory, on the one hand, usually assumes jitter free sampling and insignificant (constant) input-output latencies disregarding complex real-world timing effects. Real-time engineering theory, on the other hand, uses abstract performance and resource models that neglect the functional behavior, and derives worst-case situations that have little expressiveness for control functionalities in automotive systems. As a consequence, there is a lot of potential for a systematic co-engineering between both disciplines, increasing design efficiency and confidence. We have taken a standard control-engineering tool (Simulink) and combined it with state-of-the-art real-time system design and analysis tools (SymTA/S and TraceAnalyzer from Symtavision).

Abstract Feature Addition or Enhancement is a necessary fragment of product development. Feature Addition or Enhancement is a result of one of the following: scope addition to new product development or customer requirement on current products. When it comes to Scope Addition, most of the times, first phase design and engineering will have been completed. Feature Addition or Enhancement because of scope addition is done to improve quality, cost or marketability. Current or future customer request for a feature addition or enhancement to meet their needs leads to customer requirement Feature Addition or Enhancement. Most of the times, vehicle has already been launched and design is frozen. In both the cases, design and engineering is challenged by Time, Effort and Cost. Model Based Design approach helps save some time for implementation. It also helps to improve required effort and reduces the cost of the feature by optimization.

Abstract Toyota Motor Corporation (TMC) has been developing fuel cell (FC) technology since 1992, and finally “MIRAI” was launched in 15th Dec. 2014. An important step was achieved with the release of the “FCHV-adv” in 2008. It established major improvements in efficiency, driving range, durability, and cold start capability. However, enhancing performance and further reductions in size and cost are required to facilitate the commercial widespread adoption of fuel cell vehicles (FCVs). TMC met these challenges by developing the world's first FC stack without a humidifying system. This was achieved by the development of an innovative cell flow field structure and membrane electrode assembly (MEA), enabling a compact and high-performance FC stack. Other cost reduction measures incorporated by the FC stack include reducing the amount of platinum in the catalyst by two-thirds and adopting a carbon nano-coating for the separator surface treatment.
