2019-11-21
2019-28-2523
Most recent or all developments in the field of small UAV’s seem to use Quadcopters. It’s a valued commenting that a quadcopter is a smaller amount stable than a similar regular chopper and is additionally less economical. A Quadcopter UAV’s with four propellers is always a major concern to the society when brings to its stability as its major factor. To design and analyze the use of one propeller monocopter is the main objective of this paper. Wacky Whirler technology used here to demonstrate the passage of the monocopter. It is a single propeller powered with a coreless motor which is a modern enhancement in the UAV. It is based on the All Rotating monocopter theory. In the proposed system, controller based on IOT can be used which will be helpful in monitoring and processing the microdrone status.

2019-28-2571
Keywords – Miniaturization, Low Profile (LP) Relays, Low Profile (LP) Fuses, Fuse box, Wiring Harness Research and/or Engineering Questions/Objective With the exponential advancement in technological features of automobile’s EE architecture, designing of power distribution unit becomes complex and challenging. Due to the increase in the number of features, the overall weight of power distribution unit increases and thereby affecting the overall system cost and fuel economy. The scope of this document is to scale down the weight and space of the power distribution unit without compromising with the current performance. Methodology Miniaturization involves replacing the mini fuses and J-case fuses with LP mini and LP J-case fuses respectively. The transition doesn’t involve any tooling modification and hence saves the tooling cost.

BlockChain - A disruptive technology in Automotive Industry

2019-11-21
2019-28-2436
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.

Low Voltage Powertrain in Light Electric Vehicles

2019-11-21
2019-28-2467
Engineering objective Light Electric Vehicles (LEV) with Li-ion batteries suffer from short battery life and poor efficiency, due to low grade electronics. Battery management systems (BMS) cannot always keep the pack in balance, and after cell voltages drift, capacity of the pack diminishes and some cells may destruct, causing a fire. The paper describes a novel approach to LEV powertrains using parallel connected battery cells & control methodology that keep cells in balance naturally, thereby eliminating BMS and hence safer to use. Li-Ion cells with different chemistries can be used and superior thermal management reduces temperature rise, resulting in longer battery life. Methodology Based on the original invention by the author, the system circuit schematics was designed and simulated using OrCAD PSpice. After obtaining results from the simulation, the first prototype device was constructed and tested in laboratory.

Battery operated vehicle need accurate management system because of its quick changes in State of charge (SOC) due to aggressive acceleration profiles and regenerative braking. Li-ion battery needs control over its operating area for its safe working. So, the main objective of the proposed system is to develop a BMS having algorithms to estimate accurate SOC, predict degradation parameters, balance individual cells, manage cell temperature, and provide safe area of operation defined by voltage and temperature. Proposed methodology uses Model-based Design approach wherein nonlinear behavior of battery is modeled as Equivalent Circuit Model to compute the SOC and degradation effect on battery to decide the end of life of battery, also performing inductive Active balancing on cells to equalize the charge. proposed algorithms communicate with the vehicle ECU through CAN to assist the driver for runtime estimation, time for battery swapping, Alerts.

2019-28-2502
Predominantly the biggest question that haunts the EV Market is the charging infrastructure that should eventually ease the nervousness of the consumers and allowing EV to penetrate the Indian market with changes done within urban areas and highways. There are multitude of options available ranging from onboard charging via home charging point to a Fast DC off board charger that can be used to charge an EV. There are multiple factors that can be used to evaluate the options and their pros / cons. Some of these factors are: • Cost, time to charge, health of battery, charging and discharge rate of the battery, etc… • Convenience and availability of charging point • Ease of operation including payment • Safety and Security • Ambient temperature in which charging is done There are mainly these categories of charging options: • Residential charging based on a home charging point. The charger is mounted on the vehicle (onboard) and the EV cable can be connected to the home plug point.

2019-28-2506
India has emerged as the world’s biggest market for Two-wheelers and Four-wheeler. Besides rising incomes and growing infrastructure in all areas, one big reason for the spurt in sales has been ease of zipping in and out of chaotic city traffic along with road irregularities and potholes. Furthermore, the efficiency increase in the Shock absorber within the vehicle have high demands to use of regenerative solutions, in which e-system can be employed as to recover part of the energy otherwise dissipated in form of heat. The Smart e-Shock can charge battery and illuminate accessories of vehicle. Also, the e-shock can provide the various damping characteristics by changing the Electric load on to it to make system as Semi-Active Suspension. This Smart e-Shock system is based on unique and patented concept of constraining the reciprocating motion of the shock absorber in to a single sense of rotation of e-system and the energy is recuperated and given to the battery from the e-system.

HANDLING EXCEPTIONAL SITUATION OF AN AUTONOMOUS VEHICLE

2019-11-21
2019-28-2526
In autonomous vehicle world human safety takes highest priority. And most researchers agree that machines won't be able to completely take over driving duties for years or even decades. "Today's autonomous vehicles can drive relatively well in typical settings, but they fail in exceptional situations - and it's those situations that are the most dangerous," said Walter Lasecki, an assistant professor of computer science and engineering. "Designing autonomous systems that can handle those exceptional situations could take decades, and in the meantime, we're going to need something to fill the gap. Few companies have introduced human safety drivers in autonomous vehicles which has cost advantage compared to traditional ride sharing services. Combining human and artificial intelligence in autonomous vehicles could push driverless cars more quickly toward wide - scale adoption.
