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…

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,…

Recommended Practice for Pass-Thru Vehicle Programming

Vehicle E E System Diagnostic Standards Committee
  • Ground Vehicle Standard
  • J2534_201907
  • Current
Published 2019-07-29 by SAE International in United States

This SAE Recommended Practice provides the framework to allow reprogramming software applications from all vehicle manufacturers the flexibility to work with multiple vehicle data link interface tools from multiple tool suppliers. This system enables each vehicle manufacturer to control the programming sequence for electronic control units (ECU’s) in their vehicles, but allows a single set of programming hardware and vehicle interface to be used to program modules for all vehicle manufacturers.

S400 Copper Media Interface Characteristics Over Extended Distances

AS-1A Avionic Networks Committee
  • Aerospace Standard
  • AS5643/1A
  • Current
Published 2019-07-09 by SAE International in United States

This SAE Aerospace Standard (AS) establishes guidelines for the use of IEEE-1394-2008 Beta (formerly IEEE-1394b) as a data bus network in military and aerospace vehicles. It encompasses the data bus cable and its interface electronics for a system utilizing S400 over copper medium over extended lengths. This document contains extensions/restrictions to “off-the-shelf” IEEE-1394 standards, and assumes that the reader already has a working knowledge of IEEE-1394.

 

Vulnerability of FlexRay and Countermeasures

The importance of in-vehicle network security has increased with an increase in automated and connected vehicles. Hence, many attacks and countermeasures have been proposed to secure the controller area network (CAN), which is an existent in-vehicle network protocol. At the same time, new protocols-such as FlexRay and Ethernet-which are faster and more reliable than CAN have also been proposed. European OEMs have adopted FlexRay as a control network that can perform the fundamental functions of a vehicle. However, there are few studies regarding FlexRay security. In particular, studies on attacks against FlexRay are limited to theoretical studies or simulation-based experiments. Hence, the vulnerability of FlexRay is unclear. Understanding this vulnerability is necessary for the application of countermeasures and improving the security of future vehicles. In this article, we highlight the vulnerability of FlexRay found in the experiments conducted on a real FlexRay network. Consequently, we clarify the conditions under which attackers masquerade as legitimate electronic control units (ECUs) and transmit spoofed FlexRay frames. We also confirm that a consumer vehicle’s functions such as steering, braking,…

A Comprehensive Data Reduction Algorithm for Automotive Multiplexing

Published 2019-04-08 by SAE International in United States
Present-day vehicles come with a variety of new features like the pre-crash warning, the vehicle-to-vehicle communication, semi-autonomous driving systems, telematics, drive by wire. They demand very high bandwidth from in-vehicle networks. Various ECUs present inside the automotive transmits useful information via automotive multiplexing. Transmission of data in real-time achieves optimum functionality. The high bandwidth and high-speed requirement can be achieved either by using multiple buses or by implementing higher bandwidth. But, by doing so, the cost of the network as well as the complexity of the wiring increases. Another option is to implement higher layer protocol which can reduce the amount of data transferred by using data reduction (DR) techniques, thus reducing the bandwidth usage. The implementation cost is minimal as the changes are required in the software only and not in hardware. This article presents a new data reduction algorithm termed as “Comprehensive Data Reduction (CDR)” algorithm. The article also demonstrates a comparison of the proposed algorithm with the boundary of fifteen compression algorithms and compression area selection algorithms. The results show that the…
