  1. Introduction to Telematics Jinwon Lee NC Lab, CS, KAIST September 23, 2003

  2. Outline • What is Telematics? • Architecture • Services • Technologies • Market • Case study • Research Issues

  3. What is Telematics? • Telematics • Telecommunication + Information • Provide information into the car by using telecommunication • Key application of mobile computing

  4. Architecture

  5. Architecture (sever side)

  6. Architecture (client side) Wireless GPS sensor Wi-Fi 3G Embedded equipment AV HMI Internet Terminal in-vehicle

  7. Services • Security Service • Emergency rescue with 911 • Car location tracing (thief-proof) • Information service • Navigation assistant (real-time traffic information) • Weather, stock information • Entertainment and M-Commerce • Context-Aware and Event-base service • Vehicle Diagnostic Service • Car Insurance based on driving statistic

  8. Technologies • Wireless Network • Wide Area Network (CDMA2000 1X EVDV, 3G): 100kbps • DSRC (Dedicated Short-Range Communication) • DAB (Digital Audio Broadcasting) • Terminal • Embedded Operating System • OSGi (Standard) • LAN in the car for unit control • Bluetooth™, MOST, 1394, CAN • AMI-C(Standard) • HMI (Human Machine Interface) • Speech Recognition, TTS • GPS or sensor

  9. Standards • Open Services Gateway Initiative (OSGi) • Open specifications for the delivery of managed broadband services to networks in homes, cars and other environments. • Architecture and specifications for core platform, vehicles, devices, remote management and security • Release 3 due March 2003 • Reference: www.osgi.org • Automotive Multimedia Interface collaboration (AMI-C) • Organization of motor vehicle manufactures created to facilitate the development and standardization of automotive multimedia interfaces to motor vehicle communication networks. • Specifications for physical network interfaces, network protocols and In-vehicle software interfaces (telematics and local) • Release 2 specifications due Dec. 2002 • Reference: www.ami-c.org • Java Community Process (JCP) • Embedded Java VM.s with bolt on components and APIs • Reference: www.jcp.org

  10. OSGi - Overview • Direction towards de-facto standard for 3rd generation platforms • Operating system feature • Standard abstraction from HW w/Auto centric APIs. • Life cycle management for dynamic service deployment • Multi-tasking/function • Remote management • Java component model, security • Integrates with back-end infrastructure. • Faster time-to-market • Reduction in platform implementation and sustaining costs.

  11. OSGi - Overview

  12. Characteristic Vehicle control: Low-speed wired communication Information system: High-speed wired communication Current spec Low speed : IDB-CAN High speed : IDB-1394 vs. MOST AMI-C
