The ELVA project (Advance Electric Vehicle Architectures) was co-funded by the European Commission's 7th Framework Programme. The project was formed by a consortium of seven partners: Institute for Automotive Engineering (ika) of RWTH Aachen University; Applus+ IDIADA; Volkswagen; Renault; Centro Richerche Fiat (CRF); Continental and the Swedish Vehicle and Traffic Safety Centre (SAFER). The objectives of the ELVA project were to generate, investigate and analyse innovative design concepts for electric vehicles (EV). Also, to deliver new modular architectures with the same level of safety as today's best known practices, while minimizing weight, maximizing energy efficiency, optimizing ergonomics and interior space, all at affordable costs. The level of comfort and performance must also be improved. All of the development strategies were summarized in form of best practices, which have been made available for designers and engineers. The project characterized for strong interaction amongst the participants during the design loops.

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. The design axiomatic is a powerful theory applied into vehicle system and component level to understand the engineering design process, at both, the conceptual and detail levels and to reduce the gap among information systems.

Data analysis is an important way to validate and optimize engineering's designs. With the development of wireless transmission systems, race cars use telemetry as a solution to measure the car's behavior by the analysis of acquired data. Wireless communication systems provide the possibility to analyze data in real-time situations, allowing tactical decision making based on the vehicle's embedded signals interpretation. This paper intends to describe the design process of a wireless data transmission system applied to a Formula SAE vehicle. Based on the prototyping microcontroller Arduino™ and the radio-transmission module Xbee®, the wireless transmission system here described is capable of transmitting 16 analog and 54 digital embedded signals and can be easily adapted for the user's requirements, through the system's open-source characteristics.

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. The engine was developed based on 12 liters of displacement diesel longblock and achieved peak power of 350 kW @ 1800 rpm.

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. Those pair comparison are done until upper level of hierarchy tree, where can be found the main business goal.

The purpose of this document is to establish air conditioning design guidelines that will apply to most systems rather than the specific design of any particular system. Operating conditions and characteristics of the equipment will determine the design of any successful system, and since these characteristics and conditions vary greatly from one application to another, the designer must determine the goals expected to be reached under the conditions encountered. To determine the capacity of such items as blowers, condenser fans, condenser coils, evaporator coils, filters, compressors, etc., will require the adherence to several guidelines, some of which are outlined in this document.

The vehicle requires high brake performance and mass reduction of disc brake for vehicle fuel economy. Then disc brake will be designed by downsizing of disc and high friction coefficient pad materials. It is well known that disc brake squeal is frequently caused by high friction coefficient pad materials. Disc brake squeal is caused by dynamic unstable system under disturbance of friction force variation. Today, disc brake squeal comes to be simulated by FEA, but it is very difficult to put so many dynamic unstable solutions into stable solutions. Therefore it is very important to make it clear the influence of friction force variation. This paper describes the development of experimental set up for disc brake squeal basic research. First, the equation of motion in low-frequency disc brake squeal around 2 kHz is derived. Second, the increase of kinetic energy per 1 cycle in minute vibration is derived, which represents the influence of coupled vibration between out of plane vibration and in-plane vibration in disc and pads with caliper.

Following on from the various crises of 2009, 2010 and 2011, Toyota has surged back to reclaim the title of top global automotive manufacturer (by volume). There are a series of factors supporting this recovery, but in much the same way that the supplier community assisted the OEM to maintain output during those bad years, those same companies have been integral to the company’s on-going rebound. As the company increases output, this support has centered on managing to deliver a substantial increase in total part volumes, a difficult task after many tier suppliers had reduced production capacity in line with Toyota’s declining output over the preceding years. This has meant investing to ramp up in line with output, while still developing new technologies and working with the OEM to support production of next-generation models. The other side to the coin is that many of the preferred suppliers working with Toyota are also part owned by the OEM and many of those same companies rely on the OEM for most of their business, so there is a vested interest in supporting the carmaker.

In automotive design and development, there are different stages for product design. In this fast changing scenario product design, digital verification of design (CAE), physical validation of the product and launching of the same in short time is important in product development life cycle of any new generation vehicle. This paper proposes a new approach towards development of a green-field platform for commercial vehicles by improving reliability of CAE and thereby reducing the need for prototype testing and hence shortening development cycle and costs - we call it “Hybrid Mule”. This Hybrid Mule has complete design intent under-body and engine-house while upper-body is made of simple representative tubular space frame. FRP skin panels are attached to this space frame to create a safe environment for test-driver. FRP skin also provides early feel of styling in running condition and evaluates basic ergonomics and visibility. Hybrid Mule is developed taking into consideration all detail CAE analyses - durability, crash, NVH, attachment point stiffness, ride & handling, etc., to establish early co-relation between digital and physical worlds.

The Model-Based Development (MBD) process has been the key enabler of technical advancement. MBD helps manage complexity, while making product development faster by bringing clarity and transparency to the entire product development process, specifically software components. Developing software using MBD has required extensive, sophisticated toolchains, like the ones provided by dSPACE, that allow for efficient rapid controls prototyping, automatic code generation, and advanced validation and verification techniques with hardware-in-the-loop (HIL) test systems. MBD is an efficient iterative process that allows engineers to improve quality and deliver on demanding needs of product variants in the current competitive environment. However, the MBD process described commonly using the ‘V-Cycle’ diagram leads to the generation of large volumes of data artifacts and work products. The iterative process, variants and versions of these artifacts lead to even larger amounts of data. To maintain efficiency while continuously improving the quality of products in the MBD paradigm, it is necessary to be able to manage this data in an efficient manner that is supportive of the development process.

The growth of auto sales in emerging markets provides a good opportunity for automakers. Cost is a key factor for any automaker to win in an emerging market. This paper analyzes risks and opportunities in a low cost manufacturing environment. The Chinese auto market is used as an example and three categories of risks are analyzed. A typical risk assessment for cost reduction includes the analysis of environment risks, process risks and strategic risks associated with all phases of a product life. In an emerging market, emission regulations are a rapidly-evolving environment variable, since most countries with less regulated emission codes try to catch up with the newly- developed technologies to meet sustainable growth targets. Emission regulations have a huge impact on product design, manufacturing and maintenance in the automotive industry, and hence the related cost reduction must be thoroughly analyzed during risk assessment. Diesel engines optimized for minimum Particulate Matter (PM) engine out emission with only Selective Catalytic Reduction (SCR) are proposed in this paper as the most cost effective solution for Chinese on-highway and off-highway commercial automobiles, especially for heavy-duty trucks.

Since 1992, Caterpillar has invested millions of dollars to purchase CAD software, and spends nearly $2M per year keeping its engineers up-to-date, via instructor lead training (ILT), as new enhancements are introduced. Periodic upgrades to the software also require huge resource (people, costs) commitments for the planning and execution of the training requirements required for a large global workforce. This paper will examine gaps uncovered in the efficiency and effectiveness of the current training process, and the cultural change required as a result of switching from an instructor led environment to a completely web-based solution, which, once deployed, had promised to change the way Caterpillar approached training for the future. The proposed change promised to improve human resource capability by utilizing new technological capabilities, and resulted in improvements in organizational capabilities as well. Topics reviewed include: Reasons for initiating the change, including perceptions of the as-is process (voice of the customer), and pros/cons of the current state.
