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…

To be published on 2019-11-21 by SAE International in United States
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,…

Security Mechanism and Verification of Vehicle Network Based on Message Authentication

Nanjing University of Science and Technology-Benxiong Wang, Dawei Pi, Boyuan Xie, Hongliang Wang, Xianhui Wang
Published 2019-11-04 by SAE International in United States
In view of the relatively bare network environment of the current car controller area network (CAN) and the high-performance requirements of most existing security mechanisms for electronic control units (ECUs), based on a new and faster network transmission protocol, a lightweight car bus authentication method using Message Authentication Code (MAC) is proposed. In this case, the vehicle network is modularized in dependence on the different functional requirements of each part of the bus, calculation tasks are processed by the gateway of the corresponding network segment, the confidentiality and correctness of the vehicle network can be guaranteed by synchronizing the message authentication tables in all nodes, and the transmission rate gets obvious improvement under CAN FD (flexible data-rate) protocol as well. In this paper, the security and real-time performance of the vehicle network are verified by hardware experiments, and the impact of the encryption method on the performance in the network is verified by software simulation. The CAN FD bus is formally designed in the MATLAB environment with finite state machine. The state machine model can…

Research on Electromagnetic Compatibility for Wireless Charging System of Electric Vehicles

CATARC-Li Jiang, Haiming Liu, Yifu Ding, Xu Zhang, Yue Zhang
Published 2019-11-04 by SAE International in United States
Currently, there are no specific standards on electromagnetic compatibility (EMC) test for wireless charging system of electric vehicles (EVs). However, the EMC test items have been summarized in some international standards. And the national standard is under developing. In order to support the formulation of corresponding national standards and regulations, promote the rapid development of EVs industry and support the implementation of the national strategy of new energy vehicles (NEVs) and intelligent network vehicle, we carry out the EMC test for wireless charging systems. In this paper, the wireless charging system of EVs is taken as the research object, which can also been called equipment under test (EUT). Firstly, an introduction of the research status was summarized. And then, the influence parameters such as output power and offset are analyzed. Based on the analysis, the EMC test was implemented to evaluate the EMC performance of EUT. Finally, the relevant research results will provide support for the formulation of national standard.

Handling of Data from Heterogeneity of Vehicular Devices through Inter-Networking

VIT Universtity-Gnanaprakasam Anuradha, Kalivaradhan Ramesh Babu
Vellore Institute of Technology-Chooriyaparambil Damodaran Naiju
Published 2019-10-11 by SAE International in United States
Collection of various data from sensed data or raw availability of data from transcript or interdependency of data from various sources is a tedious task in a real time scenario like an Indian context is considered. Planning to find a solution to collect the data from various vehicular devices about the information related to the pollution becomes a cumbersome job. The need of the data, under what time duration data has to be transmitted, how they are interconnected and whether data needs to be stored or how they are processed is a major question that arise when dealing with collecting data and internetworking with various vehicular devices. A study of two different types of approaches for internetworking between the devices is discussed. One related to real time setup of mobile application and other with the dynamic cluster approach when the nodes are moving in a region was considered. Eliminating the speed of the vehicle with the movement of human formation of cluster with the mobile application to identify the various devices in the vicinity was…

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. This document does not limit the hardware possibilities for the connection between the PC used for the software application and the tool (e.g., RS-232, RS-485, USB, Ethernet…). Tool suppliers are free to choose the hardware interface appropriate for their tool. The goal of this document is to ensure that reprogramming software from any vehicle manufacturer is compatible with hardware supplied by any tool manufacturer. The U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (ARB) have proposed requirements for reprogramming vehicles for all manufacturers by the aftermarket repair industry. This document is intended to meet those proposed requirements for 2004 model year…
