We are currently in the age of developing Autonomous Vehicles (AV). Never before in history, the environment has been as conducive as today for these developments to come together to deliver a mass produced autonomous car for use by general public on the roads. Several enhancements in hardware, software, standards and even business models are paving the way for rapid development of AVs, bringing them closer to production reality. Safety is an indispensable consideration when it comes to transportation products, and ground vehicle development is no different. We have several established standards. When it comes to Autonomous Vehicle development, an important consideration is ISO 26262 for, Automotive Functional Safety. Going from generic frameworks such as Failure Mode and Effects Analyses (FMEA) and Hazard and operability study (HAZOP) to Functional Safety, Safety of Intended Functionality, and Automotive Safety Integrity Levels specific is a natural progression. This, in specific to AV development context with a renewed perspective is the need of the hour. The fundamental assumption of a human driver being part of the vehicle, considered in…

The number of fatalities due to road accidents in India is increasing at an alarming rate. In 2017, around 4.6 lakhs road accidents were reported due to which around 1.48 lakh people lost their lives. The accident severity i.e. number of deaths per 100 road accidents is reported to be at 31.8 - worst in a period of more than two decades. Passenger vehicles (two wheeler & four wheeler) constituted maximum road accidents, 59% combined. So, a strong sense of responsibility lies on vehicle manufacturers part to help the government agencies to reduce road accidents in India. Majorly road accidents are caused due to bad driving habits, road infrastructure problems, vehicle quality issues, unfavorable weather conditions and India unique chaos on roads. This paper highlights use of telematics to counter road accidents caused by bad driving habits of Indian drivers. Out of the bad driving habits, in 2017, over-speeding accounted for 67% of the road accident deaths. Any connected vehicle solution is capable of capturing basic parameters like vehicle speed, Global Positioning System (GPS) location…

"According to Data on Road accidents in India by Transport Research Wing of Ministry of Road Transport & Highways, more than 4 Lakhs road accidents happened every year from year 2003 to 2017. Poor road conditions and badly designed roads are the common cause of road accidents besides the driver's negligence. Poor roads and badly designed speed breakers are common in developing countries. Apart from accidents, poor road conditions can cause excessive fuel consumption & damage to vehicles. Road condition monitoring solutions aim to warn the drivers of upcoming bad patch on the road and optionally report road conditions to authorities. There are multiple existing solutions that use motion sensors and GPS to detect a bad patch on the road. The presented solution builds over capability of existing solutions by adding useful features making it more practical and useful. The presented scheme is able to differentiate between a pothole and a speed breaker using a machine learning based approach. It also employs additional sensors like gyroscope and optionally a camera to detect on which side…

This paper proposes a model to implement a blockchain network that can host a system of autonomous vehicles which communicate through generic V2V protocols like DSRC and CV2X. The blockchain will be designed to function like a global database for V2V communication. The purpose behind the proposal of this model was to ensure a transparent and secure network between all autonomous vehicles which indirectly leads to reduced traffic congestion and takes us a step closer to zero crashes. This is made possible by the blockchain ledger’s enhanced encryption systems.

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. This retrofittable design can provide better vehicle dynamics-with various driving modes (Comfort, Normal, Sport,…

In a connected vehicle environment, the engine drive cycles operate in synchronized and regulated manner. This requires smooth transitions for improved CO_2 footprint. To arrive at this, there is need for intelligent and faster airpath control at transients. Authors aim to model and control every actuator of a coupled system in a synchronized manner with faster dynamic response. The turbocharger control is vital and forms heart of the system; This demands accurate position prediction of VTG. Deriving a control law for turbocharger is challenging due to the hybridized nature of turbocharger models in engine management system. It becomes extremely critical to estimate accurately, the position of VTG without introduction of any sensing devices. The control engineer always need to solve the trade-off between the controller performance KPI’s – rise time, transient response, controllability, observability and capability – stability and dynamics response etc. Author propose a model which improve the performance and capability of VTG control. Author presents a novel technique to model VTG position. A neural network based supervised learning model is derived. The model…
