2019-28-2516
In this paper we propose the snow mobility vehicle in order increase the mobility and decrease the risk of accidents for carry food and medicines on snow bounded areas using unmanned tracked vehicle called as snowmobii 2.0. Our unmanned tracked vehicle can transport Food/medicines as well as Defence in snow bounded areas. This unmanned robot can run in loose as well as hard snow due to it have specific featured technology in base wheel(track wheel system) such as hub with outer seals that improve its durability. The proposed snow mobility vehicle is consist of many sophisticated-designed systems such as navigation system, obstacle detection system, communication system, temperature sensing system. Snowmobii 2.0 is easy to get command and enable significant reduction in losses of many solder’s precious lives due to unavailability of food and medicines at that place.

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.

Reliability states the degree to which the result of a measurement, calculation, or specification can be depended on to be accurate. And, tests according to GMW specifications represents a minimum of 15 years of vehicle life time with defined Reliability and Confidence level. In this work, actual number of thermal cycles for Thermal Fatigue tests (Thermal Shock and Power Temperature Cycle) are calculated for Copper Wire whose Coffin Manson exponent is 5. Overstressing the PEPS Antenna under thermal fatigue requirement (defined number of thermal cycles based on Reliability and Confidence requirements) will lead to broken Copper wire which will result in component’s functional failure and thus impossible to continue reliability testing. The objective of this paper is to determine thermal fatigue requirements for Antenna’s Copper wire whose Coffin Manson exponent is 5.

This paper presents the design of Inverted F antenna and its effects in size, efficiency and compactness. The antenna is analyzed in terms of return loss, bandwidth, directivity and gain by using same and different dielectric substrate materials with same and different thickness of Inverted F antenna. The important parameters of Inverted F antenna are L, W, S and ξr has its own impact in antenna characteristics. This parametrical effect is studied and verified. As thickness of dielectric substrate increases, the gain & directivity of rectangular Inverted F antenna decreases and bandwidth increases. As ξr increases, the size of the antenna decreases but when height of dielectric substrate increase antenna size also increases. There will be always a compromise between miniaturization and other antenna characteristics. This antenna is designed for microstrip feed line technique and with center frequency (f0) at 2.4GHz.

Infotainment has been always an important aspect of life which has made its way to car design. The cars today are much more advanced compared to their predecessors. The in-vehicle infotainment advancements have followed the consumer electronics market in terms of technologies such as Touchscreen, App based Navigation, Voice Assistant and other multimedia services. This trend is going to expand further as smartphones have revolutionized the infotainment domain with awareness and accessibility to customers. The infotainment system in the cars are expected to be connected not only to the cloud but various vehicle controllers to display host of information & controls at customer`s fingertips. To design a system that supports connectivity to both cloud and vehicle is challenging in terms of cost and design for the OEMs. With focus on Indian market condition and global trends, this paper analyzes the customer expectation for Connected Infotainment system.

The need for dedicated development of indigenous electric power-train is becoming much essential in the recent times with upcoming trends and policies. Hence, The validation and optimization of the newly developed electric power-train becomes much crucial in order to ensure smooth real world operation. This can be only possible in E-motor test benches with dedicated equipment for thorough evaluation. Also, there are no practical limitations to check the peak characteristics in a controlled laboratory environment. Initially, the motor is setup by mechanically coupling with the dynamo-meter and the controller in the open loop method with constant parameters to check steady state operability without load or external parameters that affect the torque production and speed of the drive. Then progresses to closed loop method incorporating the feedback control and external parameters including torque loading at the shaft from the dynamo-meter.

2019-28-2471
Objective Automotive sector is rapidly moving towards electric vehicle. BLDC motor is gaining popularity in the field of electric vehicle due to its high torque to weight ratio and simple control. In this paper we will focus on Switching loss characterization of 3 kW GaN based BLDC drive for electric vehicle. To improve efficiency of drive gallium-nitride based power transistor is used instead of Si MOSFET. GaN devices enable the design of inverter at higher frequencies with improved power density and efficiency as compared to traditional Si MOSFETs. Methodology In this paper commercially available GaN devices compared with Si MOSFETs. The power devices, which are selected for the performance comparison, are EPC2022 GaN by EPC, GS61008P GaN by Gan System and SiDR668DP Si MOSFET by Vishay. The Switching losses analytically predicted in MATHCAD tool and then compared with SPICE simulation losses. Double pulse test circuit is used to find out power losses of power transistors.

In-Vehicle Directional Audio Streaming

In-Vehicle Infotainment has evolved greatly over years from a simple tuner based radio with a small LED display to a complex system with highly intelligent interactive HMI which can mirror the smart phone. The full-fledged entertainment features like watching videos are restricted to only rear passengers. In drive mode, drivers are limited with access to only audio to avoid driver distraction. Rear passengers and drivers are classified into different audio zones. Each of the rear passengers are equipped with headsets so that audio merging with driver zone can be avoided. This leads to passenger discomfort, as many passengers would not prefer to hook up with headset all the time. Now the automotive world is envisioned to reach fully autonomous mode where there is no driver and every passenger is interested to listen to music/video of diverse interest. The audio zones in autonomous car need not be zonified or linear. Circular audio zone can also be a good choice for autonomous cars.
