1 Leveraging Tizen IVI Platform for Realizing V2X Use Cases Purnendu Sinha Tizen IVI Team Samsung R&D India, Bangalore

2 Outline V2X Applications and their Requirements Use Cases Introduction to Tizen IVI Benefits Tizen IVI offers Realizing V2X Apps on Tizen IVI Examples Conclusion All examples presented here are for illustration purposes only!

3 V2X Applications Navigation/LBS/PoI GPS navigation providing info/content to the driver/ passenger Maintenance/Optimization Remote diagnostic application Telemetry to collect data to fine tune car performance monitoring Safety/Security In-vehicle tracking system Automatic security distance maintaining system Commerce Mobile payment system (charging tolls, parking fees) Premiums for car insurance correlated to driving patterns

4 Classes of V2X Applications Cooperative Road Safety Primarily refers to ultracritical safety requirements; example includes collision avoidance, pre-crash sensing, emergency hard-braking, etc. Cooperative traffic efficiency deals with traffic fluidity; example includes traffic light optimal speed advisory, congestions alerts and new route suggestions, etc. Cooperative local services provides on-demand information on commercial/non-commercial stuffs; example includes maps update, e-advertising, media download, etc.

5 ITS Classes and Requirements

6 Collaborative Driving with V2V Location-based service Road Advisory Situation-aware Alerts Smart OBU in Vehicle #1 3G/LTE Wi-Fi Direct 3G/LTE Wi-Fi Direct Smart OBU in Vehicle #3 Smart OBU in Vehicle #2 3G/LTE Wi-Fi Direct Travel/hazardous situation advisory Traffic optimization Fleet Management Emergency/disaster management Road Side Unit Internet Connectivity Server on the Internet Forms an ad-hoc network of vehicles

7 In-Vehicle Comm. Bus (e.g., CAN) Advanced Driver Assistance Apps Sensors Cloud-based Advisory Motion Planning or, could be connected via CAN bus 3G/LTE Gateway Integrated Vehicle Control Actuators ETH Smart OBU ADAS apps Cloud Connectivity Intersection cross traffic collision warning Traffic congestion warning Enhanced route/navigation guidance

11 A Typical Web Application Scenario Private/ Public Cloud Server Mapping Server 3G/LTE Network OBU

12 An Emergency Response Web Application Detect that a crash has occurred Determine the location of the crash Send out an Emergency SMS to the pre-specified emergency numbers about the crash with location information

13 Tizen Vehicle APIs Provides getting and setting data items Mechanisms for event based updates to requested data items Implements a method for a Web application to query for supported data items get(eventlist, successcb, errorcb) Retrieve the specified data values, or all data values if blank set(eventlist, valuelist, successcb, errorcb) Set the specified data values getsupportedeventtypes(type, writeable, successcb, errorcb) Retrieve the list of events available on the platform subscribe(eventlist, successcb, errorcb) Subscribe to update events for the specified data items unsubscribe(eventlist, successcb, errorcb) Unsubscribe from update events for the specified data items Source: W3C Web and Automotive Workshop, Nov 2012

17 Example 2

18 Re-Routing under Crash Notification Gets the crash information from the cloud server. It then calls the geo location API s and gets the current location of the vehicle from the location manager. the mapping API s to calculate the distance to the crash location and displays it. the rerouting API s from the mapping service rerouting by avoiding the crash location. Note: the MapQuest open data API s are used.
