1 In the Driver s Seat Use Cases of Qt in Automotive Dr Tuukka Ahoniemi Product Manager tuukka.ahoniemi@theqtcompany.com

2 Contents Requirements for Automotive Systems Transition of Automotive Software Power of Ecosystem Qt GUI Offering Qt Quick and HTML5 Qt Automotive APIs Why Qt Makes a Lot of Sense in Automotive?

3 The Automotive Industry is Changing Software Will Take Over the Form Factor

4 Wild West of Automotive Systems The automotive systems are mostly based on specialized hardware and proprietary software OEM solutions Tier 1 Platform solutions Open source solutions Apple, Google platforms Alliances and consortiums, like GENIVI and AGL Still far from standardized platforms

5 Requirements for IVI Systems Flexibility and Scalability Customization for different makes and models, and for setups Different HW Plugins Global presence: internationalization/localization Fluent performance Multitasking Fast boot-up, pre-loading

6 Multi-Screen Challenge

7 A Platform is Only as Good as the Content for the Platform

8 Building your Automotive Ecosystem Biggest value for the consumers and for the car brand comes with innovative automotive applications and services which developed and controlled by OEM. Applications extend functionality infotainment system not only inside but also outside of the car. Qt s Application Framework provides fast and safe basis for the OEM s applications and services The Qt Company

9 Target All Your Platforms with One Technology Qt s cross-platform SW framework runs all major Operating Systems with native speed. Investing one technology instead of many brings huge cost savings. Embedded: Embedded Linux, Embedded Android, Windows Embedded, QNX, VxWorks, INTEGRITY Desktop: Windows, Linux, Mac, Solaris, Enterprise UNIX My Software Solution Mobile: Android, ios, Windows Phone, WindowsRT, BlackBerry 10, Sailfish 2015 The Qt Company

11 Transition of Industry

12 From Black Box Systems into White Box

13 Requirements for More Transparency Build Systems Contribution model Sharing Code Style Comments Language

14 Power of Ecosystem

15 The Qt Ecosystem 20 years of experience and knowledge of Build systems Porting Qt to various platforms (OS and HW) Open Source contribution model (Qt Project) CI (Continuous Integration) systems Documentation, tutorials, examples Companies, partners Around million developers People writing content

16 Customer Case: Porting Example Qt for Renesas R-Car Customer had legacy build system Once build system was fixed, getting Qt on top of that was easy Small backend implementation for eglfs Uses general KMS API Runs on Intel platforms -> desktop development, rapid workflow Then, porting to NVidia Jetson TK-1/ Jetson Pro Same KMS API than Renesas Different buffer mechanism Took only 1 week to adopt Qt stack

17 Why Qt Solved the Problem? Qt gives you a wide HW support out-of-box and very flexible and easy ways of customizing the stack into other HW Flexibility is built-in to Qt This is very unique in the Automotive world Often OEMs have hundreds of people working for a proprietary stack, where as with Qt, a handful of people can handle that

19 Create Modern Automotive GUIs with Qt Qt Quick Declarative UI, C++ backend Designer/Developer workflow Full touch-based experience Existing UI controls, easy customization Smooth and easy animations 3D effects Integration of 3D graphics Localization 19

20 XML Bluetooth Positioning NFC Serial Port Rapid Workflow with Qt Quick Qt Quick Declarative UI Design Designer Stunningly Fluent Modern User Interfaces, written with QML. Ideal for rapid UI prototyping. Imperative Logic Power of Cross-Platform Native Qt/C++ Developer Core Network Sql Processes, Threads, IPC, Containers, I/O, Strings, Etc. HTTP FTP SSL SQL & Oracle Databases + Direct Hardware Access

22 Example Case: Modernizing Workflow with Qt Quick A large automotive OEM Designers used ipads 6 weeks from design to running on car Changed the workflow to Qt Quick based Immediately see the change in real environment Same kind of agility for embedded / automotive development than on desktop/mobile Rapid workflow Modern software development

23 Qt and HTML5 Qt and HTML5 are not mutually exclusive Qt provides a powerful HTML5 engine, Qt WebEngine Convenient port of the Chromium Cross-platform Fully integrated into the Qt graphics stack Everything else around the engine -> the whole Qt framework!

24 Experiences with HTML5 from Customer Cases HTML5 is not designed for GUI creation Inconveniences Performance problems HTML5 is very good for some use cases and needed for certain dynamic cross-platform functionality Qt wants to provide the best platform for HTML5 as well We strongly recommend a wise hybrid development strategy Qt Quick for the GUI controls and graphics, for best native performance HTML5 for the rest Mix and match freely

25 Experiences with HTML5 from Customer Cases Start testing in real hardware as early as possible Developing Qt or HTML5 on desktop is nice but might give an unrealistic view of performance or possible features Integration introduces problems that are too late to be fixed properly Upgrade and select Qt WebEngine as the engine, and do it from the start Even the old Qt WebKit will introduce performance issues on real usage Qt tooling for Embedded gives rapid development workflow for embedded Rapid design-develop-deploy-test cycles on real hardware Wiser development strategy Shorter time-to-market

26 Contents of the Qt Automotive Suite Offering

27 Quick Look to Qt Automotive APIs Qt Speech Speech recognition (PocketSphinx, Nuance VoCon) Qt SerialBus CAN Bus Other Buses, for various industries, FlexRay (planned) Qt Virtual Keyboard SCXML Qt Quick Controls ISO Automotive icons Qt Automotive API (planned) W3C Automotive API implementation

28 CAN Bus Qt SerialBus will provide a CAN Bus API Technology preview with Qt 5.6 Different CAN Bus backends supported: Vendor Backend Brief description CAN over Linux sockets SocketCAN CAN bus backend using Linux sockets and open source drivers. PEAK-System PeakCAN CAN bus backend using the PCAN adapters. MHS Elektronik TinyCAN CAN bus backend using the Tiny-CAN adapters

29 Qt Virtual Keyboard A complete virtual keyboard solution Solid C++ backend and versatile Qt Quick UI Fully customizable graphics and styling Extendable input methods and word prediction engines Support for different keyboard layouts Good language support, also from left-toright Handwriting recognition Supports also 5-way or 2-way navigation 2014 Digia

30 Qt State Chart Offering Existing: Qt State Machine Framework Existing for many years in Qt Core Bug fixes, performance improvements Improved compatibility with SCXML standard New: Qt SCXML Compiler and Runtime New module developed by The Qt Company, not yet released SCXML parser and runtime SCXML Compiler: similar to Qt Quick Compiler, produces C++ binary of the state machine Coming: State Chart Editor Plugin for Qt Creator Edit State Charts directly within Qt Creator Textual editing Visual drag & drop editor SCXML Editor SCXML Compiler & Runtime Qt State Machine FW SCXML extension 2015 The Qt Company
