Abstract Voice of customer is typically captured through multiple connect points like surveys, warranty claims, social media, and so on. Customer verbatim is collected through these connect points to encourage free expression of opinion by customers. Such verbatim data is generally of high value and is typically analyzed using Natural Language Processing (NLP) techniques for translating into influencing actions in manufacturing, customer service, marketing, and product development departments. One of the challenges in analyzing unstructured verbatim data is to map that data onto appropriate concern codes (CCCs), which are typically used in automotive firms for tracking quality and satisfaction metrics. These concern codes map to a hierarchy of function areas in the organization aimed at improving product, service and hence the customer’s overall experience.

Abstract For achieving viable mass customization of products, product configuration is often performed that requires deep understanding on the impact of product features and feature combinations on customers’ purchasing behaviors. Existing literature has been traditionally focused on analyzing the impact of common customer demographics and engineering attributes with discrete choice modeling approaches. This paper aims to expand discrete choice modeling through the incorporation of optional product features, such as customers’ positive or negative comments and their satisfaction ratings of their purchased products, beyond those commonly used attributes. The paper utilizes vehicle as an example to highlight the range of optional features currently underutilized in existing models. First, data analysis techniques are used to identify areas of particular consumer interest in regards to vehicle selection.

Abstract The automotive industry is rapidly expanding its Hybrid, Plug-in Hybrid and Battery Electric Vehicle product offerings in response to meet customer wants and regulatory requirements. One way for electrified vehicles to have an increasing impact on fleet-level CO2 emissions is for their sales volumes to go up. This means that electrified vehicles need to deliver a complete set of vehicle level attributes like performance, Fuel Economy and range that is attractive to a wide customer base at an affordable cost of ownership. As part of “democratizing” the Hybrid and plug-In Hybrid technology, automotive manufacturers aim to deliver these vehicle level attributes with a powertrain architecture at lowest cost and complexity, recognizing that customer wants may vary considerably between different classes of vehicles. For example, a medium duty truck application may have to support good trailer tow whereas a C-sized sedan customer may prefer superior city Fuel Economy.

Abstract Political and social trends in the automotive industry production and consumption have changed in the last decade, driving a demand for more efficient, low-fuel consuming, clean vehicles in most markets nowadays. Recently the demand for such vehicles has been increasing and emerging markets are no exception; automakers all around the world have invested heavily in developing new electrification technologies that would comply with the newer and stricter regulations and environmental policies, being Start-Stop systems one of the preferred approaches due to their lower complexity and cost compared to full and mild hybrids. Mexico stands out as a challenge for the implementation of this technology due to its wide range of altitudes, temperatures, traffic jams, and some other contributing factors that can hinder this type of application – especially in its bigger and more populated cities.

Abstract In order to design the in-wheel motor (IWM) for Electric Vehicles (EV), it is necessary to analyze the desired (expected) duty cycle at a higher performance level in order that the IWM becomes commercially relevant. The duty cycle may be representative of different segments of the customer base. Or, the individual customer may wish to have a set of IWMs that uniquely meet his/her measured “demand” cycle for a balance of drivability and efficiency. Questions then arise: How to measure the demand cycle of an individual? What 2 or 3 standard duty cycles should be offered as customer choices for their vehicle? Should the IWM represent multiple speed domains to enhance efficiency and drivability? Can the vehicle be updated rapidly 2 to 3 years after purchase? Etc. In this paper, we lay the groundwork to answer these types of customer questions for an EV with four independent IWMs.

Abstract The competition among automotive industries increases each year worldwide. Among their diverse needs, what can be highlighted are: market expansion, model diversification, competitive prices, customer-recognized quality, new products release in shorter time periods, among others. The occurrence of flaws that might compromise the health or safety of the product’s user is admittedly one of the largest issues for any manufacturer, especially if these flaws are identified after its commercialization (recall). In this work, a study on recall in the automotive industry in the Brazilian market will be presented, comprising the years of 2013 and 2014. Reasons and causes of recall are addressed, based on the sample of the aforementioned research, with special emphasis on flaws derived from the production process. The conclusion at the end of the work is that the final assembly in the automotive manufacturing process is what requires more attention from engineering area.

Abstract Public transport has been considered the preferred strategy to reduce congestion and pollution from urban road traffic. For low to medium capacity, bus systems are considered the most affordable and flexible mode. Currently, diesel based systems still dominate transit bus market, due to their high productivity, low deployment costs, technological maturity, operational reliability and flexibility (high daily ranges, fast refuelling and no infrastructure requirement along the routes). However, although some important improvements in engine technology and aftertreatment devices, enforced by emission standards improvements (Euro VI, US 2010 and those related), have been achieved, it is well known that there is a limit to cleaning exhaust diesel buses exhaust. In this context, transit authorities and operators have been under pressure to shift for more environmental friendly technologies.

Abstract The evaluation of perceived comfort inside a car during the early stages of the design process is still an open issue. Modern technologies like CAE (Computer Aided Engineering) and DHM (Digital Human Modeling) already offer several tools for a preventive evaluation of ergonomic parameters for car drivers using detailed CAD (Computer Aided Design) models of car interiors and by a MBS (multi-body-system) solver for evaluating movements and interactions. Such evaluations are, nonetheless, not sufficient because the subjectivity of comfort perception is due to factors that are very difficult to evaluate in the early stage of design. Physical prototypes are needed and these are often too expensive to be realized.

This paper presents the method of designing an optimized light weight, cost effective planetary gearbox for a Formula Student vehicle. The gearbox has a high speed functioning capability, in addition to the compact size and light weight. The iterative optimization procedure used provides a technique for selecting the best possible configuration of the gearbox. Conventional gearboxes used for this purpose are generally two step reduction gearboxes, which are bulkier in terms of weight and volume. Also, a review of the existing market reveals that the planetary gearboxes manufactured in India are not capable of handling high speeds, thus rendering them futile for racing applications. The target reduction ratio for the gearbox is a fixed parameter. The method involves design and optimization of the gear-train with the calculated ratio.

Abstract This paper presents a mathematical model of an electric driveline consisting of one battery pack, two independent Permanent Magnet DC (PMDC) motors and motor-controllers and two fixed-ratio planetary gearboxes, all located inside the rear frame of the vehicle. The proposed analysis has been performed with the objective of: (i) Determination of acceleration run time for a straight patch of 75 meters; (ii) Determination of lap times and energy consumption for endurance track of 23 laps. A model of a PMDC motor and motor controller has been developed based on response analysis by conducting experiments on a jig setup. The motor controllers are compared for two control modes- Speed mode and Torque mode. A simplified race car model for longitudinal vehicle dynamics is derived from forces acting on the car including the effect of losses due to drag forces, rolling resistance, transmission inefficiency and inertial losses due to rotary elements.

The current automotive industry and todays car drivers are faced with every increasing challenges, not previously experienced. Climate Change, financial issues, rising fuel prices, increased traffic congestion and reduced parking space in cities are all leading to changes in consumer preferences and the requirements of modern passenger vehicles. However, despite the shift in the industry dynamics, the principal layout of a car hasn't changed since its invention. The design of a ‘conventional’ vehicle is still principally a matchbox with four wheels, one at each corner. The concept has served its purpose well for over 100 years, but such a layout is not suited to solving today's problems. To address the range of problems faced by the industry, a number of alternative commuting vehicles have been developed. Yet the commercialization of these ‘alternative’ vehicles has yet to be successful.

Software has become the driving force behind innovation in the automotive industry. According to a recent Frost & Sullivan market research report, “Strategic Analysis of the European Market for Software in Passenger Cars”, the software for passenger cars in Europe accounted for 5.8% of the cost of vehicles in 2004. The same report projects an annual growth rate (CAGR) of 15.5% until 2011, when software is expected to represent 11.0% of the cost of vehicles. This paper discusses the emerging AUTOSAR standard (AUTOSAR release 2.0), which aims to address the need for more efficient E/E (Embedded Electronic) automotive architecture solutions. The paper also provides a review of the mapping of a few key AUTOSAR concepts to their Simulink counterparts, which should help designers using Simulink deliver AUTOSAR compatible solutions. Finally the paper features a component of an experimental engine management system that has been remodeled in Simulink to conform to the AUTOSAR requirements.

This paper is a report of the findings and insights derived from a continuously variable transmission (CVT) Cyber Bulletin Board Group study. When a new technology is introduced to the car market, a small number of early adaptors brace the technology. Several stakeholders are interested in getting the feedback from these customers. However, it is very difficult to recruit sufficient customers to complete a meaningful market research at any one location. Along with scattered and small customer base, high cost of the traditional market research is a major roadblock. Cyber research method is very useful and low-cost technique to obtain customer feedback effectively and efficiently. Nearly all CVT owners are satisfied with CVT however it will not be a driving force for a repeat purchase. Few consumers were concerned about purchasing a vehicle with a new technology but brand ownership & reputation convinced them to make the purchase.

Although market research has indicated that there is significant demand for a supersonic business aircraft, development of a feasible concept has proven difficult. Two factors contributing to this difficulty are the uncertain nature of the vehicle’s requirements and the fact that conventional design methods are inadequate to solve such non-traditional problems. This paper describes the application of a multiobjective genetic algorithm to the design space exploration of such a supersonic business jet. Results obtained using this method are presented, and give insight into the important decisions that must be made at the early stages of a design project.

The genetic modification of oilseeds has been a critical step in the evolution of biodegradable, non-toxic vegetable oil-based industrial fluids. Oils that are high in oleic acid possess the required properties for many industrial applications and have been successfully used as hydraulic fluids and numerous lubricants. Recently, the DuPont Co. has developed high oleic soybean varieties that produce oil with greatly improved oxidative stability. This oil provides the opportunity to make environmentally acceptable industrial fluids that may be lower in cost and/or functionally superior to vegetable oil-based fluids currently on the market. Research and testing over the last year has focused on utilizing genetically modified soyoil for industrial applications. Using standard bench tests and low volume fluid power pump tests, experiments were conducted to develop a soybean oil-based hydraulic fluid in cooperation with Lubrizol Corporation.

Automotive cabin air filters have become increasingly popular as automotive manufacturers recognize the need to provide vehicle occupants with a more comfortable driving experience. Cabin air filters which reduce particulates (e.g. dust, pollen) have been standard on many European models since the late 1980's and have recently become available on several vehicles produced by Ford Motor Company in North America. Market research (focus panels and customer surveys) has shown that consumers expect cabin air filters to reduce both particulates and odors/gases and as a result, future vehicles will offer systems which address both. Test methods and standardized test codes for evaluating these types of filters are currently being drafted. Current methods for testing such gas/odor filters call for part-per-million challenge levels for reasons of analytical simplicity and test speed.
