To reduce the incidence of whiplash-associated disorders caused by rear impacts, head restraints should be closer to the head which decreases the amount of relative motion and it is believed to reduce the risk of soft tissue neck injury. Drivers are raising complaints that the head restraint causes discomfort by interfering with their preferred head position, forcing them to select a more reclined seat back angle . This paper is about the importance of head restraint system and how it can be improved by adjusting the angle between the head restraint and passenger`s head. It is essential to carry out research on head restraint that can be adjusted in forward and backward direction letting the cost of seats remain in budget.
When i decided to buy a second hand car from a dealer to learn driving, i was sceptical of the mileage usage for which a particular price was charged. Though the well know dealer told me a about the car, its previous usage, the fact that there were no accidents, and so on, there was no reliable way to verify what the dealer was offering. In order to solve such issues, we are looking at a disruptive technique which will cause a complete paradigm shift - by using blockchain technique. This paper talks about the basics of the blockchain technology and its relevance in automotive industry. We also look at some real life scenarios, where this technology helps to build reliability as one of the implicit requirements. We will start looking at how the block chain will help to reliably select the right components in the assembly line. Also we look at different aspects of software architecture like security and how blockchain can provide solutions in this area.
This paper investigates and proposes the possibilities of standardizing the software/firmware package format and flash jobs in order to provide the possibility of productizing the update-over-the-air solution regarding on-board vehicle components and make use of it in all OEMs with minimum configuration changes and customization. The update-over-the-air solution in the automotive sector is provided by various suppliers and needs to be customized to meet various OEMs requirements. Possible Variants of OEM requirements are: • Variant 1 o Customer Portal + Backend + vehicle on-board components solution from supplier • Variant 2 o Customer Portal + Backend solution from OEM o Vehicle on-board components from supplier • Variant 3 o Backend from OEM o Customer Portal + vehicle on-board components from supplier ODX, VBF, and many other formats from OEMs include software/firmware packages.
DEVELOPMENT OF A FLEET MANAGEMENT SYSTEM FOR AN OFF-HIGHWAY VEHICLE V.Jagannathan 1.a* , B.Jaiganesh 2.b & S.Sudarsanam 3.c Mahindra & Mahindra Limited, Mahindra Research Valley, Mahindra World City, Anjur PO, TN, India Corresponding author Email- V.JAGANNATHAN@mahindra.com Managing an off-highway vehicle fleet during validation is a challenging task. Complexity is acquainted when more than 100 vehicles with different horse power (hp) & with different product configuration working across India and other parts of countries. Traditionally, a tractor validation involves data collection such as usage hours (Hour meter reading on cluster), locations etc. which are recorded in spread sheet and updated to the respective project owners on daily basis through mail communications. A manual recording and consolidation of tractors validation status is prone to error, reiterative work, consumes more resource and effort.
Research Objective The objective of the paper is to research what are the changes in experiences being brought about due to the advent of Electric Vehicles (EVs). EVs are silent, have less complex propulsion system, and have free space under the hood, amongst other things. Each change brings about both good and bad experiences across the spectrum of users. Some of the bad experiences can be safety incidents leading to death as well. Researching the areas that are harmful to end users, including pedestrians, will be our focus area. Methodology Our methodology will look at the changes at the vehicle architecture level which are inherent to the EV design. Research how are the experiences so far due to these changes. Are these just inconveniences or safety hazards? EVs have excellent NVH characteristics. A farmer may love a silent tractor, but a racing enthusiast may not like a relatively silent sports car.
The use of deposit control additives in European market gasoline is well documented for maintaining high levels of engine cleanliness and subsequent sustained fuel and emissions performance. Co-ordinating European Council (CEC) industry fuels tests have played a crucial role in helping to drive market relevant, effective and low-cost deposit control additives into European market fuels. Until now, there has not been a Gasoline Direct Injection engine test available to fuel marketers in any market globally. However, a new CEC engine test is currently being developed to address that gap. Based on an in-house VW injector coking test, it shows promise for becoming a useful tool with which to develop and measure the performance of deposit control additives. A key requirement of industry tests should be to replicate issues seen in consumer vehicles, thereby providing a platform for relevant solutions.
Title Development of a Graphical User Interface (GUI) Based Tool for Vehicle Dynamics Evaluation Authors Mr. Shubham Kedia, Dr. Divyanshu Joshi, Dr. Muthiah Saravanan Mahindra Research Valley, Mahindra & Mahindra, Chennai Objective Objective metrics for evaluation of major vehicle dynamics performance attributes i.e. ride, handling and steering are required to compare, validate and optimize dynamic behavior of vehicles. Some of these objective metrics are recommended and defined by ISO and SAE, which involve data processing, statistical analysis and complex mathematical operations on acquired data, through simulations or experimental testing. Due to the complexity of operations and volume of data, evaluation is often time consuming and tedious. Process automation using existing tools such as MS Excel, nCode, Siemens LMS, etc. includes several limitations and challenges, which make it cumbersome to implement.
Generally brake pads are manufacturing by use of asbestos materials, these materials are chemically harmful and toxic, affects human health. The present investigation fabricates polypropylene composites with mixing constant volume [5 Vol.%] of alumina nano particles and different volume percentages [0%, 5%, 10% & 15%] of basalt fibre by hand layup compression technique. The wear characteristics of polypropylene matrix composites were tested by dry sliding condition using pin on disc apparatus configuration with hardened steel counter-face at elevated temperature. The load was applied 30N to 70N with the interval of 20N and varying of sliding speed 300 rpm to 900rpm with the interval of 300rpm for the time period of 0-180 sec. The wear rate was decreases with addition of alumina nano particle and also increases the frictional force for the effect of basalt fibre content present in the composites. The co-efficient of friction was increases from 0.1 to 0.66 under normal loading condition.
Currently automotive industry is facing bi-fold challenge of reduction in Greenhouse gases emissions as well as low operating cost. On one hand Emission regulations are getting more and more stringent on other hand there is major focus no customer value proposition. Engine blow by gases are one of the source of Greenhouse gases emission from engine. Blow by gases not only consist of unburn hydrocarbons but also carry large amount of oil. If oil is not separated from these gases, it will led to major oil consumption and hence increase total operating cost of Vehicle. In this paper, effort has been taken to develop a low cost closed crank case ventilation with oil mist separation system on diesel engine.
