Although the concept of Integrated Vehicle Health Management (IVHM) can be complex in its implementation, it is essentially based upon a simple idea: the more you know about a particular machine’s ability to function, the quicker you can act to prevent malfunctioning. This rapidly developing area of engineering seeks to enable better management of both the vehicle and vehicle fleet health. Use of IVHM can improve vehicle reliability, safety, and reduce unnecessary, unscheduled maintenance through the use of diagnostic and prognosis systems that monitor data and overall vehicle health. From an initial idea by the SAE IVHM Steering Group, these books have been collaboratively written by experts from academia, research and industry, and represent the collective voice of the most qualified authorities in the field.

The Indian automotive industry is currently going through one of its most challenging phases so far. Vehicle sales are set to register a negative growth in 2013 – first time in more than a decade – compared with the previous year. Official data shows that vehicle sales in India declined at a high single-digit rate year on year in the first nine months of 2013 compared to 2012. This downward spiral has prompted automakers and suppliers to cut production to avoid excess inventory build-up. Besides, there’s little respite on the cost front. Though there has recently been some softening in raw materials prices, other costs such as wages, cost of power and finance expenses, continue to erode suppliers’ operating margins. The Indian automotive industry at the moment is facing multiple challenges such as slowing economic growth, high inflation and high interest rates – compared with many of its peers.

AS5643B
This SAE Aerospace Standard (AS) establishes the requirements for the use of IEEE-1394b as a data bus network in military and aerospace vehicles. It defines the concept of operations and information flow on the network. As discussed in 1.4, this specification contains extensions/restrictions to “off-the-shelf” IEEE-1394 standards, and assumes that the reader already has a working knowledge of IEEE-1394. This document is referred to as the “base” specification, containing the generic requirements that specify data bus characteristics, data formats and node operation. It is important to note that this specification is not stand-alone - several requirements provide only example implementations and delegate the actual implementation to be specified by the network architect/integrator for a particular vehicle application. This information is typically contained in a “network profile” slash sheet that is subservient to this base specification.

The focus of this paper is the process of implementation and integration of a series-parallel multiple-regime plugin hybrid electric vehicle (PHEV) using a 2013 Chevrolet Malibu as a platform. The University of Victoria EcoCAR team used a 3-year vehicle development process (VDP) modeled after those used by major automotive manufacturers, and maintained by the rules of EcoCAR 2: Plugging into the Future. Intensive research and simulation resulted in selection of UVic's series-parallel multiple regime vehicle architecture during year 1 of the EcoCAR2 competition. Detailed mechanical design refinement has been conducted to allow final fabrication and integration of components. This has included detailed structural analysis and comparison with the stock vehicle, dynamic analysis of vehicle suspension changes, and manufacturability and serviceability improvements to the year 1 vehicle design.

The Hybrid Electric Vehicle Team (HEVT) of Virginia Tech has achieved the Year 2 goal of producing a 65% functional mule vehicle suitable for testing and refinement, while maintaining the series-parallel plug-in hybrid architecture developed during Year 1. Even so, further design and expert consultations necessitated an extensive redesign of the rear powertrain and front auxiliary systems packaging. The revised rear powertrain consists of the planned Rear Traction Motor (RTM), coupled to a single-speed transmission. New information, such as the dimensions of the high voltage (HV) air conditioning compressor and the P2 motor inverter, required the repackaging of the hybrid components in the engine bay. The P2 motor/generator was incorporated into the vehicle after spreading the engine and transmission to allow for the required space.

The Pennsylvania State University Advanced Vehicle Team (PSUAVT) is one of sixteen collegiate teams across North America participating in the EcoCAR 2: “Plugging In to the Future” competition. The PSUAVT designed and implemented a series plug-in hybrid electric vehicle (PHEV) for this competition. This architecture allows the vehicle to operate as a pure electric vehicle until the energy storage system (ESS) state of charge (SOC) is depleted. The auxiliary power unit (APU) then supplements the battery to extend range beyond that of a purely electric vehicle. To implement this design concept, the PSUAVT re-engineered a General Motors (GM) donated 2013 Chevrolet Malibu to house an electric traction motor, high capacity lithium-ion battery pack, and APU consisting of a low-displacement engine fueled by 85% ethanol/15% gasoline (E85) mixture and an electric generator.

The largest automobile companies have several corporate, regulatory and customer requirements to integrate into engineering of development [1]. These information need to be split in technical team called disciplines as electrical, chassis, powertrain, etc. The advanced engineering team is responsible to conduct this process with general purpose of facilitating the managing and tracking of creation and execution of the total vehicle/system. However, the interrelation, complexity and lack of engineer's know-how of these systems have been creating innumerous issues into development, launch, manufactory and quality. Insufficient dedicated tools, requirement definitions and poor initial programs formulation are some reasons of these issues. It means that the ability applied in advanced engineering principles and analytical techniques in an automotive engineering context have to be improved.

Regarding fuels research and development, some preliminary studies - low cost and short time - can be conducted before the traditional engine tests - more expensive and time consuming. Therefore, experimental apparatus, such as a rapid compression machine (RCM) and specific methodologies, such as imaging techniques, are very useful in order to simulate engine combustion with simplicity, agility and flexibility, reducing development time and costs. Imaging techniques allow flame front propagation and ignition delay analysis, which are important parameters to understand fuel performance in engines and also to improve fuel modeling in engine simulation softwares. A RCM was adapted to operate in a spark ignition engine mode. It was used to obtain high-speed photos of flame propagation and ignition delay. Contour plots of the flame front profiles were obtained in successive frames to analyze the flame development with gasoline-ethanol blends.

The aim of this paper is to define a project prioritization method in automotive company by using the AHP methodology (Analytic Hierarchy Process) aligned to the organizational strategic objectives. Nowadays there is no method of prioritizing engineering projects in the organization object of this study, indicating that they are prioritized over individual interests or analyzes of individual criteria. There is no interdependency among assessed criteria and neither if those criteria are directly aligned with business goals. An alternative to solve this typical problem is the application of a mathematical model for project prioritization, such as AHP. AHP methodology is an excellent tool for decision makers support, since it creates an hierarchy for all criteria and gives weight for each one, unstructured or subjective some times, changing from intangible perceptions to measurable values by pair comparison.

Brazil has been a leader for the past 30 years in the development and commercialization of vehicles powered by ethanol, which contributes significantly to maintain the basic Brazilian energy less dependent on fossil fuels, but its usage was restricted to small vehicles with focus on gasoline replacement. Whereas the use of diesel fuel has significant impact on emission of greenhouse gases when it is compared to the whole production cycle of the alternative fuels (“well to wheel” analysis), these fuels have been the focus of studies, applications, federal government programs, and also the private sector, such as bio-diesel, sugar cane diesel, ethanol with additive for diesel cycle and diesel-gas Dual-Fuel. This paper will detail the development a high efficient engine fueled with 100% hydrated ethanol capable to achieve up to 42% of break efficiency, similar to a diesel efficiency running on Otto cycle.

A frequent situation in the national automobile industry is the each time bigger rapidity that just-launched models are evolved (the so called face-lifts). Within this highly dynamic context, the solutions and technical proposals developed by the local product engineering have two main guidelines. The first one is to work on product evolutions which goal is to make the vehicles far more attractive and differentiated with respect to the competition and also to the previous model. The second one is to constantly search the standardization or the modularization of parts between the different models and versions of vehicles, thus reducing the costs of investments and providing scale profits.
