Multi-zone application development Automotive Linux Summit Kevron - PowerPoint PPT Presentation

Multi-zone application development Automotive Linux Summit Kevron Rees Fall 2013

Agenda • Zone defined • Automotive Use-cases that require zones • Automotive Message Broker (AMB) • AMB Zones API • Filling the Use-cases • Security Concerns

Zones Defined Zone is a specific location inside the vehicle.

Zone Defined - ctnd

Use Cases

Use cases The same Seat Position Application running in each zone wants to • set Seat Position. Driver wants to use an Application to activate child lock for his • young child Driver wants to set the temperature for the front of the car in a 3+ • zone vehicle.

Automotive Message Broker Zones API

Automotive Message Broker Zones API AMB provides vehicle data to applications.

AMB Zones API AMB organizes data into logical DBus paths: • /{source_id}/{zone_number}/DataObject AMB provides a “Manager” API to discover the different • DataObjects

AMB - High level

AMB - Manager The manager interface allows applications to: Find sources for a specific vehicle data object (FindObject) • Discover zones for a given vehicle data object • (ZonesForObjectName) Get a vehicle data object from a specific zone (FindObjectForZone) • List all supported vehicle data objects (List) •

AMB - Manager

Zones in AMB 6 Zone “masks” • and a “nozone” •

Common Zone combinations

DataObject example /{source_id}/{zone_number} /DataObject

Where are my zones?

DataObject interface

Use-cases fulfilled!

Use cases The same Seat Position Application running in each zone wants to • set Seat Position. Driver wants to activate child lock for his young child. • Driver wants to set the temperature for the front of the car in a 3+ • zone vehicle.

Use Case: The same Seat Position Application running in each zone wants to set Seat Position. Discover the current application zone {gap}. 1. DBus API: manager.FindObjectForZone(“SeatPosition”, myZone) 2. web api: var seatPosition = tizen.vehicle.get(“SeatPosition”, 3. myZone)

Use Case: Driver wants to activate child lock for his young child DBus API: manager.ZonesForObjectName(“ChildLock”) 1. App Displays the zones to Driver. 2.

Use Case: Driver wants to activate child lock for his young child DBus API: manager.ZonesForObjectName(“ChildLock”) 1. App Displays the zones to Driver. 2. Driver selects a zone 3. obj = manager.FindObjectForZone(“ChildLock”, 10) 4. Driver sets child lock to “true”. 5.

Use Case: Driver wants to set the temperature for the front of the car in a 3+ zone vehicle.

Use Case: Driver wants to set the temperature for the front of the car in a 3+ zone vehicle. var zones = manager.ZonesForObject(“HVAC”) 1. foreach(zone in zones) if(zone & Zone.Front) //set temp 2.

Security We don’t want apps in certain zones to access other zones: • Example: Child zone to set Driver zone’s seat position •
