Micro Hybrid Systems are essentially first step towards the electrification of the powertrains. They are aimed at improving the fuel efficiency of the conventional gasoline and diesel power trains with conventional 12 V electrical system, and thus reduce the CO2 emissions as well. Various technologies like Engine Stop-Start, Intelligent Alternator Control, and Electrical Energy Management Systems are included in the bracket of micro hybrid systems. These system functions demand a totally different approach for managing the SLI battery, which is a total departure from the conventional approach. Particularly, the Alternator Shutdown function of Intelligent Alternator Control maintains a calibrated average level of State of Charge, which is typically around 80%, to ensure that the battery can accept more current, during the energy recuperation, which indirectly improves fuel economy.

A steady increasing share and complexity of automotive software is a huge challenge for quality management during software development and in-use phases. In cases of faults occurring in customer’s use, warranty leads to product recalls which are typically associated with high costs. To avoid software faults efficiently, quality management and enhanced development processes have to be realised by the introduction of specific analysis methods and Key Process/Performance Indicators (KPIs) to enable objective quality evaluations as soon as possible during product development process. The paper introduces the application of specific analysis methods by using KPIs and discusses their potential for automotive software quality improvement. The aim is to support quality evaluation and risk-analysis for the release process of automotive software.

Topology optimization is an effective tool to find the optimal structural layout in the concept design stage of the automotive industry. Mostly, topology optimization is carried out with linear finite element analysis because of its simplicity. However, in the real world, structural problems always involve various nonlinear and dynamic responses. Thus, there is a growing requirement to consider crashworthiness performance in the topology optimization process of the automotive development. In current study, a topology optimization method based on equivalent static loads method (ESL) is proposed to optimize an automotive body in white (BIW) subjected to representative crash loads. The chosen load conditions are frontal impact, side barrier impact, roof crush and high speed rear impact.

The constant motivation for lower fuel consumption and emission levels has always been in the minds of most auto makers. With legislation playing a huge part in order to protect the environment. For instances, based on ICCT reports, EU passenger cars, weighing 1500kg, for today (2015) would need to meet the CO2 emission of 130g/km. This target is reduced to 95g/km in 2020. For the Chinese market, according to their CAFC target for passenger cars of 2015, has to meet the 6.9L/100km fuel consumption which translates to 163gCO2/km. At 2020, this target has been further reduced to 5L/100 which translate to 120gCO2/km. Though this is less than that of EU’s, the trend of fuel consumption and emission reduction is obvious and legislation needs to be met. Gasoline Port fuel injection has been a matured system for many years and cars sold in emerging markets still favor such system due to its less system complexity and cost.

The Security Development Lifecycle (SDL) is a software development process that helps developers build more secure software and address security compliance requirements while reducing development cost. The SDL process has been developed to appropriately outline the development process specifically for the consumer electronics oriented mindset. Unfortunately this approach does not always correlate to an appropriate approach from the automotive OEM mindset. This paper will analyze the current SDL process in detail and provide suggestions with improvements to the overall SDL process creating an Automotive Security Development Lifecycle (ASDL).

In general, driving performance development of a vehicle is focused on satisfying preference of average customers. But there is no single standardized setup which can fulfill various driving tastes of all drivers, since they are different by gender, culture, age group, and personal habits. To resolve this issue, automotive companies have introduced selectable drive mode buttons which drivers can manually select desired drive mode among Normal, Eco, and Sport. These manually selected multi-mode systems provides variety of choices than single-mode system, but it still is a transitory solution which induces inconvenience of requiring drivers' effort to select and frequently change preferred drive mode in volatile driving situations. Also, it is a questionable supposition that categorizing complex needs of drivers into 3 modes is sufficient.

This paper proposed a novel concept of Integrated Energy-recuperation retarder (IEER). Facing the conventional eddy current retarders’ (ECR) braking torque attenuation under high speed domain and the poor braking property of the regenerative brake (RGB) in low speed domain, the IEER is designed to take the advantages of both the ECR and the RGB to overcome their disadvantages. The IEER integrates the rotary eddy current retarder (RECR) and the RGB, both of which share a stator. Slots are grooved on the stator of the IEER, and armature-windings are inserted in slots. Poles are arranged on the rotator. Eddy currents are excited in the stator core, and the current is excited in the armature-windings. Braking torque of the IEER produced by stator core and armature-windings can stack together, and therefore the IEER can provide greater braking torque than the RECR. Besides, the IEER can recover electric energy from armature-windings.

Thought leaders identify Model Based Systems Engineering (MBSE) as a solution to the extreme design challenges caused by EE complexity. This presentation explores how coherency in early stage design can be applied across the entire EE life cycle. Starting from functional abstractions, we introduce a new lightweight solution to evaluate & guide optimized implementations for integrating software, networks, devices, and connectivity. The pattern used for this and the data created can be directly driven into downstream, domain-specific design flows delivering lower costs, better quality, and faster innovation.

Toyota has been a global leader in hybrid vehicle technology since the launch of Prius, the first mass produced hybrid electric vehicle, in 1997. The introduction of the 2nd and 3rd generation Prius (2004, 2009) saw vehicles with significantly improved performance, including fuel efficiency. Toyota introduced Li-ion batteries into its hybrid lineup with the launch of the Prius Alpha (Japan, EU) in 2011.  Adopting a compact Li-ion battery resulted in sufficient cabin space for a 3rd row of seats while maintaining the expected high fuel efficiency of the Prius. Pre and post- vehicle launch, an extensive list of performance tests were run on the Li-ion battery pack, including electrical, electrochemical, mechanical, and safety. The evaluations were performed in the lab, in the field (demonstration fleets) and by acquiring vehicles used by customers. The MY16 Prius (4th generation), to be launched in 2015, will offer a Li-ion battery pack.

The overall automotive industry is moving toward first time right test which in turn needs first time right analysis. This is due to the enormous pressure of cost, mass, time to market and availability of prototype vehicles for testing. Use of finite element methods enables to upfront predict the system behavior in operating conditions and evaluation of structural strength. In vehicle product development process, hood slam durability evaluation is one of the important test for body closure structure. Current work showcases an effort made for developing virtual Hood slam test. The virtual model consists of BIW, hood, hinge joint, interface like CRFM and latch mechanism with spring preload. Analysis performed with LSDyna solver. An impact loading is applied by converting potential energy to kinetic energy, mimicking the hood dropping from a specified height on the hood latch.

Simulation models based design has become the common practice in automotive product development. Before applying these models for product development, model validation needs to be conducted to assess the validity of the models by comparing model predictions with experimental observations. It is vital to develop appropriate validation metrics for intended applications. When dealing with multivariate systems, comparison of multiple quantities of model prediction and test data would lead to conflicting decisions. A Bayesian decision metric derived based on the error minimization criterion is exploited to address this issue. To further improve the performance of classification of the mathematical classifier, data processing algorithm of MSDC (Maximum Scatter Difference Criterion) is employed. MSDC helps to transform data into a proper space so that the attributes of two types of validation decisions (rejecting and accepting) are easily distinguished.

Increasingly advanced engines are having high degrees of flux in design, hardware, and requirement changes throughout the development process from initial design intent to production, all occurring at various points in the V cycle. New EGR schemes, VGT, VVT/VVL, and direct injection are part of new engine designs, coupled with 6-10 speed transmission or electric motors for increasing overall efficiency while maintaining performance. Developing and calibrating the control systems required to extract the best possible performance of these applied technologies is becoming a complex and resource consuming task when time, money, and test beds become scarce. Therefore, an equally rapid means to test completely new engine designs, new algorithms and optimized calibrations is required.

One of the key premises of the ISO 26262 functional safety standard is the development of an appropriate Technical Safety Concept for the item under development. This is specified in detail in Part 4 of the standard – Product development at the system level. The Technical safety requirements and the technical safety concept form the basis for deriving the hardware and software safety requirements that are then used by engineering teams for developing a safe product. Just like any other form of product development, making multiple revisions of the requirements are highly undesirable. This is primarily due to cost increases, chances of having inconsistencies within work products and its impact on the overall project schedule. Good technical safety requirements are in fact the foundation for an effective functional safety implementation.

DC motors are the most controllable electrical machines but more complicated for fabrication in comparison with induction motors having simplified design but more complicated for control. Regular DC motor contain excitation (field) coil on the stator and armature coil on the rotor. Armature coil connected with external voltage source by a mechanical commutator with brushes. This arrangement complicates fabrication of DC machine, increases its cost, lowered reliability and demands regular maintenance. Electromagnets inside of the stator increase dimensions of DC motor. In DC motor with salient pole rotor, there are no coils on the rotor and mechanical commutator with brushes are eliminated and eliminated all disadvantages connected with this arrangement. In this paper, we consider the new version of DC machine with DC stator excitation which we presented earlier.

The main aim of our gearshifter system is lightness, compact packaging and versatility. To reach that target our solution was to develop an “Electronic, Electro-actuated gearshifter and clutch controller”. It is made of three main subsystems: shifter DC motor, clutch servo and Control Unit. The system has to be reliable, fully customizable and capable of modulating the clutch release to allow any driver to start the car without shutting off the engine. Its power consumption is 50 to 70% higher if compared to pneumatic or hydraulic shifters but it does not need to be reloaded with gas (a problem that gives a limited useful life) and there are no oil, hydraulic valves and pressurized pipes passing through the car. The engine generator can accomplish the task of charging the battery with no modifications. The whole system weights between 40 and 80% less than any other shifting system and its known that low weight means higher performances.

Thermal management systems (TMS) of armored ground vehicle designs are often incapable of sustained heat rejection during high tractive effort conditions and ambient conditions. Latent heat energy storage systems that utilize Phase Change Materials (PCMs) present an effective way of storing thermal energy and offer key advantages such as high-energy storage density, high heat of fusion values, and greater stability in temperature control. Military vehicles frequently undergo high-transient thermal loads and often do not provide adequate cooling for drivetrain subsystems. During this conditions gear oil temperatures can rise over 200°F in less than thirty minutes. This work outlines an approach to temporarily store excess heat generated by the differential during high tractive effort situations through the use of a passive PCM retrofit thereby extending the operating time, reducing temperature transients, and limiting overheating.

Today's strict fuel economy requirement produces the need for the cars to have really optimized shapes among other characteristics as optimized cooling packages, reduced weight, to name a few. With the advances in automotive technology, tight global oil resources, lightweight automotive design process becomes a problem deserving important consideration. It is not however always clear how to modify the shape of the exterior of a car in order to minimize its aerodynamic resistance. Air motion is complex and operates differently at different weather conditions. Air motion around a vehicle has been studied quite exhaustively, but due to immense complex nature of air flow, which differs with different velocity, the nature of air, direction of flow et cetera, there is no complete study of aerodynamic analysis for a car. Something always can be done to further optimize the air flow around a car body.
