QNX Architecture

Why HTML5 for Auto

Build on something bigger than automotiveEcosystem – developers, tools, companiesStandards – no vendor lock-inFlexibility – fluid deployment and architecturesBranding – brand same app on different cars with CSSLifespan – will be supported for long timeTime to market – easy to use and leveragePowerful – rich application environmentCross-platform – deploy apps on phones and car

Other SolutionsAndroid

Compatibility limited to Android devices

Android not yet automotive grade

MirrorLink

Responsiveness lacking today

Solves phone to car problem, nothing else

TIZEN IVI in Jaguar LandRover

The proof of concept has been created on openly available hardware with an Intel CPU, using the Tizen open source Linux distribution as a software platform with latest HTML5 graphical user interface. Tizen was chosen as a GENIVI compliant reference.http://www.tizenexperts.com/2013/04/jaguar-land-rover-kerjasama-dengan-xchanging-dan-arynga-untuk-update-software-tizen-ivi/

Genevi/LGE code example

// Define constants for transmissionGearTypevar TRANSMISSIONGEARTYPE_AUTO = 1;var TRANSMISSIONGEARTYPE_MANUAL = 2;// Get a transmission gear type from VehicleInfoEventvehicle.get("vehicleinfo_transmissiongeartype", handleVehicleData, handleError)

function handleVehicleData(data) { if (data.transmissionGearType == TRANSMISSIONGEARTYPE_AUTO) { console.log("Automatic transmission equipped"); } else if (data.transmissionGearType == TRANSMISSIONGEARTYPE_MANUAL) { console.log("Manual transmission equipped"); }}

Tizen code example

navigator.vehicle.get("HVAC", onsuccess, onerror); function onsuccess(value) { var hvacsettings = value; value.AirflowDirection = value.AIRFLOWDIRECTION_FRONT | value.AIRFLOWDIRECTION_DEFROSTER; navigator.vehicle.set("HVAC", value, onsetsuccess, onerror);}function onerror(e) { window.console.error(e.message);}function onsetsuccess() { window.console.log("success!");}

QNX code example

//define a callback functionfunction myCallback(audioMixerItems) { //iterate through the changed items for (var i = 0; i < audioMixerItems.length; i++) { console.log( //a car.audiomixer.AudioMixerSetting value "audio mixer item setting = " + audioMixerItems[i].setting + '\n' + //a car.Zone value "audio mixer item zone = " + audioMixerItems[i].zone + '\n' + //a numeric value "audio mixer item value = " + audioMixerItems[i].value + '\n\n' ); }}

var watchId = car.audiomixer.watchAudioMixer(myCallback);

Webinos code example

 // checking if driver door is openend. vehicleService is the vehicle service, // discovered through the webinos Discovery API,  // that has been selected by the user   vehicleService.vehicle.addEventListener("doors", doorHandler); function doorHandler(doors){  if(doors.driver){        document.getElementById("info").innerHTML = 'Please close driver door';  }   }
