2019-28-2559
The Automotive industry is in ever more need for a lesser weight car due to progressively stringent emission norms and the demand of customer to have better mileage. It can be a gargantuan challenge for automotive manufacturers to search for lesser weight material to meet both customers as well as regulatory norms. But in some cases such lower weight material can increase the cost and adding a expensive material which increases overall cost to a price sensitive market like India is not favorable. One such solution is using the indigenous plant fiber (Jute) in combination with propylene (PP) to make Interior plastics components. Jute a vegetable fiber also referred to as "the golden fiber" has high tensile strength, low extensibility and is well established in fabric, packing, agriculture, construction industries. The biodegradable Jute lesser weight & abundance (India is the leading manufacturer of the Jute) can be utilized in making automobile trim parts in India.

Electrification System Modeling with Machine/Deep Learning for Virtual Drive Quality Prediction

2019-11-21
2019-28-2418
A virtual 'model' is generally a mathematical surrogate of a physical system and when well correlated, serves as a basis for understanding the physical system in part or in entirety. Drive Quality defines a driver's 'experience' of a blend of controlled responses to an applied input. The 'experience' encompasses physical, biological and bio-chemical perception of vehicular motion by the human body. In the automotive domain, many physical modeling tools are used to model the sub-components and its integration at the system level. Physical Modeling requires high domain expertise and is not only time consuming but is also very 'compute-resource' intensive. In the path to achieving 'vDQP (Virtual Drive Quality Prediction)' goal, one of the requirements is to establish 'well-correlated' virtual environments of high fidelity with respect to standard test maneuvers. This helps in advancing many developmental activities from a Controls and Calibration aspect.

In-Vehicle Directional Audio Streaming

2019-11-21
2019-28-2448
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.

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.
