In the automotive industry several attributes needs to be considered for the development of a new vehicle which are important for the customer, such as vehicle dynamics, driveability, fuel consumption, emissions, durability and NVH among many others. Sometimes these characteristics are conflicting and often need is to create a robust trade-off where the design space is sufficient to fit all of them in a vehicle that rhymes with the brand image and is appealing to the intended customer. Automobile manufacturers try to meet the requirements with respect to quality and comfort and often, emotional, aspects supercede the previous objective, pragmatic demands. The satisfaction of the demands by the customers concerning comfort, driving pleasure, design appears dominant and functionality criteria sometimes takes a back seat. NVH is considered to be one of the key buy in factor among the above mentioned attributes. This paper discusses on how the NVH aspect plays an vital role to get a competitive advantage over other vehicle aspects Moving from traditional approach of - ‘Test -Analyse -Fix’ to ‘Design Right First Time’ has been experienced.

This paper is about downsizing for off road vehicle diesel engines. While fuel efficiency has to be improved, future Diesel engine emission standards will further restrict vehicle emissions, particularly of nitrogen oxides. Increased in-cylinder filling is recognized as a key factor in addressing this issue, which calls for advanced design of air and exhaust gas recirculation circuits and high cooling capabilities. Two stage turbocharging applied to off road diesel engines is a promising solution for enhancing rated power, low end torque, transient performance, better low-speed torque, longer turbo life and optimized fuel efficiency. In the new engine design, two turbochargers are arranged in series to generate increased air pressure, airflow and a superior turbocharging effect. At high altitudes, 2-stage turbocharging technology guarantees the engine's operational performance by compensating for the reduced air density. However, a trade-off is required to match some conflicting issues, i.e. overall dimensions, cost, emissions control and performance.

To sustain market leadership position one has to continuously improve their product and services so that on one hand customer expectations are met and on the other hand business profitability is maintained. Value engineering is one of the approach through which we can achieve these two objectives simultaneously. Enhancing the value of running products is always a challenge as there is limited scope and flexibility to modify the current design and processes. Value engineering approach, integrated in product development cycle, brings great opportunity to upgrade the new and running products. This study reveals approach to upgrade the base engine of Maruti Alto. Upgraded engine is used in Alto 800 vehicle launched in October 2012. Improvement points were studied based on the business requirement, market competition, and legislative requirements. Based on functional improvement points, all the design parameters were studied and finalized. Finalized design parameters were evaluated and verified in actual testing and results were compared with the targeted values.

All electric vehicles have at least one traction motor, so the market for electric vehicle traction motors is one of the largest markets for electric vehicle parts and a primary determinant of the performance and affordability of a given vehicle. Indeed, IDTechEx Research finds that in 2013 44.6 million electric motors will be needed for vehicles, rising to 147.7 million in 2023. Today, the motors that propel electric vehicles on land, through water and in the air are mainly brushless because brushed commutator motors are on the way out. Most of the number and the value of those brushless traction motors lies in permanent magnet synchronous ones, notably Brushless DC "BLDC", a form with trapezoidal waveform, and Permanent Magnet AC "PMAC", a type with a sinusoidal waveform. No matter: they both have excellent performance including simple provision of reverse and regenerative braking. However, that dominance is about to change. The main reason is not those well publicized but elusive in-wheel motors coming in at two to six per vehicle but simply the move to much larger vehicles and therefore motors.

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. This groundbreaking set addresses both basic and advanced concepts critical for the understanding of IVHM, along with the commercial justification for the adoption of a new modus operandi in asset health management, and its impact on business strategy and technology.

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. IHS however is sanguine about the country’s growth trend in the medium to long term, and forecasts recovery in vehicle sales in 2014, and high single-digit growth in vehicle sales for the rest of this decade.

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. In a similar manner, the electrical characteristics of the bus media, as well as connector information is contained in a “physical layer” slash sheet, that also may be unique to a particular vehicle application.

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. Simulation and modeling work to improve the realism of the vehicle simulation for the purposes of control system development was also conducted.

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. Along with the challenges of properly mounting and integrating powertrain components, considerable effort was required to develop a proper hybrid control algorithm that maximizes overall system efficiency, minimizes harmful emissions, provides superior performance, and safe, reliable operation.

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. This spreading of the components meant a redesign of the front powertrain mounts and integration of a torque damper as an interface with the combustion engine and P2 motor.
