As we transition towards Internet of Things (IoT) - humans are connected to each other & outside world through the smartphone. Customers tend to use smartphones for varied purposes ranging from communication to entertainment. However, the concern of distraction exists due to poor visibility & accessibility of the phone's screen in driving condition. One of the repercussion of being connected to smartphone particularly in driving condition includes higher number of road accidents due to distraction. This paper explains one of the key initiatives taken by Maruti Suzuki India Limited to address the same. This is done by offering an entry level connected infotainment system which comprises of the following three components: (a) An entry-level infotainment with basic display & vehicle connectivity, (b) A Dock mounted on infotainment panel enabling safe usage of smartphone due to its position i.e. accessibly and visibility in driving condition, (c) A Driving App specifically designed for driving usage where one can access calling, messaging, navigation on the go with a vibrant UI & easy to use gestures. The infotainment unit…

A V2V communication protocol to avoid Blind turn accidents and accidents happen

Nowadays the sonar system is used to avoid accidents, which is not effective in case of high-speed at blind turn situation or through side crossing in high ways. That's because vehicle position is not along the line and speed is very high so sonar will not detect danger within avoidable time limits. it seems we need to develop some fast enough system to avoid these type of accidents.

Vision based solution for auto- maneuvering of vehicle for emerging market: Author/Co-Author: Singh Ashwani, SDV Ram Kumar, Bose Souvik, Lalwani Chandraprakash General Motors Technical Centre India Key words: Image Processing, Gap finding, virtual/Imaginary lines, Advance Driver Assist System (ADAS), Vehicle to vehicle(V2V)/Vehicle to Infrastructure(V2I/V2X) Research & Engineering Objective: For the various levels of autonomous, the current perception algorithms involve considerable number of sensor inputs like cameras, radars and Lidars and their fusion logics. The planning route for the vehicle navigation is done through map information which is highly volatile and keep changing many at times. Existing steering assist feature during a curve is available by combining additional driver monitoring camera & 360 degree camera. The complexity is very high in the implementation and computation of these algorithm. These solutions are not cost-effective for emerging markets. Non-availability of required infrastructure in developing countries is one of the additional constrain. Feature unavailability due to road infrastructure (ex: poor or no lane markings), bad weather will lead to higher customer dissatisfaction. The objective is to develop a logic/study…

Proposed Model to Implement a Blockchain for Secure Vehicle to Vehicle Communication

General Motors Technical Center India-Surya P. Palavalasa
  • Technical Paper
  • 2019-28-2433
To be published on 2019-11-21 by SAE International in United States
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,…

Connected Vehicles – Ecosystem for Services in Car

Automotive Software-Prabha Baragur Venkataram
  • Technical Paper
  • 2019-28-2447
To be published on 2019-11-21 by SAE International in United States
This paper outlines the different aspects of the Connected Vehicle concept. The blocks required to implement a Connected Vehicle infrastructure is also discussed in detail. Two main types of short-range wireless communication are discussed in Connected Vehicles context namely Vehicle-to-Vehicle (V2V), and Vehicle-to-Infrastructure (V2I) communication. An overview of the evolution of the Connected Vehicle and its operational aspects are presented together with its application. The impacts and potential operational benefits of the Connected Vehicle are discussed. The various challenges to architect non functional requirements in the case of Connected Vehicle technology are identified and discussed.

Data connectivity in HARSH ENVIRONMENTS

SAE Truck & Off-Highway Engineering: August 2019

  • 19TOFHP08_03
Published 2019-08-01 by SAE International in United States

Ensuring high-speed data transmission requires OEM designers to think more about components, placement and the impact of environmental conditions early in design.

Technology advances are increasingly bringing a new level of connectivity to industrial and commercial vehicles. Customers are demanding functionality that automates or enhances operational tasks to increase driver productivity and safety and, in many cases, also brings down total cost of ownership.

Daimler Trucks abruptly hit the brakes on its platooning activities, announcing at CES 2019 in January that analysis of its years-long testing on U.S. roads showed no business case for truck platoons due to less-than-expected fuel savings and difficulty in establishing and maintaining platoon formations. Silicon Valley-based Peloton Technology, on the other hand, is hitting the accelerator, unveiling in July the development of a new SAE Level 4 (L4) Automated Following solution.

Dedicated Short Range Communications (DSRC) Performance Requirements for V2V Safety Awareness™ ASN File

V2X Vehicular Applications Technical Committee
  • Ground Vehicle Standard
  • J2945/2A_201907
  • Current
Published 2019-07-01 by SAE International in United States

This Abstract Syntax Notation (ASN.1) File is the precise source code used for SAE International Standard J2945/2. As part of an international treaty, all US ITS standards are expressed in "ASN.1 syntax". ASN.1 Syntax is used to define the messages or "ASN specifications". Using the ASN.1 specification, a compiler tool produces the ASN library which will then be used to produce encodings (The J2945/2 message set uses UPER encoding). The library is a set of many separate files that collectively implement the encoding and decoding of the standard. The library is then used by any application (along with the additional logic of that application) to manage the messages. The chosen ASN tool is used to produce a new copy of the library when changes are made, and it is then linked to the final application being developed. The ASN library manages many of the details associated with ASN syntax, allowing for subtle manipulation to make the best advantage of the encoding style.
