3 The Context Automotive market main trend: Electronic content is growing significantly both in amount and complexity: new cars are increasingly executing tens of millions of lines of software code, controlling everything from brakes to the volume of the radio Market competition is constantly getting hard: this calls for lower product development time-to-market and cost

4 Electronic Content Timeline Single-point crash sensor Vehicle immobilizer Occupant sensing Rollover sensing Steer-by-wire Brake-by-wire Drive-by-wire Adaptive cruise control Stability control Lamps Horn Radio Generator Starter Breakerless Ignition Alternator Cruise control Electronic fuel injection Electronic transmission control Trip computer Service indicator Antilock Breaking Cellular phone Multiplexing Diagnostics Navigation systems Remote keyless entry Integrated powertrain control Electronic instrument cluster Traction control Adaptive suspension Crash-sensors diagnostic Theft-deterrent systems Side-impact sensor Tire-pressure sensing Electrical content of vehicles (%)

5 The Challenge The Instrument Cluster is the main human interface device for the car status is required to enhance the driving experience, offering a variety of driver-information applications (such as rear view parking camera, GPS navigation, real-time traffic and weather) Traditional clusters, with mechanical gages, little data display and lights are evolving into digital instrument clusters

6 Magneti Marelli Target Develop a reconfigurable instrument dashboard prototype using a display TFT which completely replaces traditional cluster

7 Digital Cluster Advantages Added features of a digital instrument cluster: Displayed information can be changed according to the drive mode Driver distraction is reduced by displaying only the information that the driver needs in that specific situation Mechanical constraints are overtaken: needles can be semitransparent, scales not linear Different and more information (PWT, under board, video cameras, safety, telematics, ecodriving, ) can be integrated into a single system Display is freely customizable by the driver altering the color, wallpaper, or gauge layout

8 The Requirements 1. Layout reconfigurability Possibility of dynamically change information displayed enhancing user experience 2. Innovative operation Overcoming of mechanical constraint and integration with non traditional devices (camera, DVD...) 3. Cost reduction To deploy the same hardware across multiple vehicle lines simply by reskinning the graphics 4. Easily interchangeable data entry mechanism Both for instrument cluster real version or prototype ones 5. Software portability Allowing development chain optimization and respecting product constraint

9 The Solution Provide heterogeneous skilled resources, focus on methodology enhancement and keep an overall approach Optimized workflow Graphic, SW, HW experts Overall approach

10 Project Definition WHAT? HOW? DATA INPUT APPLICATION LOGIC ANIMATION STATIC GRAPHIC Simulated Data Real Data Application Logic Animation Skin 1 Skin N Automatic code generation Manual (Automatic in future) Automatic code generation Automatic code generation

11 System INPUT ARCHITECTURE OUTPUT CAN BUS B-CAN/C-CAN BI-PROCESSOR System H8S/CAPRICORN CAN BUS B-CAN DVD/CAMERA DISPLAY TFT Navigator Input DISPLAY 7 Digital/Analog Input Digital/Analog Output

12 Software Development Methodology A Model-Based Design approach is implemented It leverages on 3 main pillars: Modeling Auto Code Generation Auto Test Generation (Future) Starting from the model, it enables work team to easily and intuitively compose a customized digital instrument cluster, modifying the display logic presentation

13 Development Tools MULTI PHOTO SHOP MS VISUAL STUDIO CAN Case USB 1 USB ADAPTER CUSTOM CABLE E6000 EMULATOR HEW SW DEEP SCREEN RS232 HW I/O Simulator E6000 HDI ALTIA DESIGN FLASH PROGRAM BOARD USB 2 RENESAS FDT CANgen JTAG CONNECTION GHS PROBE ETHERNET

14 WHAT HOW How Does It Work CONTENT DEFINITION GRAPHIC DEFINITION SW DEVELOPMENT (H8S HEW Toolchain) SW DEVELOPMENT (CapM Green Hills Toolchain) GRAPHIC DEVELOPMENT (PHOTOSHOP) INTEGRATED SOFTWARE PLUG IN AUTO CODE GENERATION (ALTIA) COMPILE FLASH ON BOARD SYSTEM

15 Overall Approach 1. Optimize Workflow Automatic code generation, new tools developement 2. Optimize Tool Usage Use of xml for graphic, enhancement suggestion on third party tools 3. Optimize Graphic Graphics/Creative team ideates effective animations 4. Optimize HW Interface Boot sequence, memory layout, low level drivers 5. Optimize SW Design&Developement Strong modular design, coding rules

16 In Practice An evolute development environment allows Everyone work efficiently both on PC and on taget Rapidly and automatically prototipe different vesions

17 Innovative Development Cycle Through tools chain: As a result: Final product can be assembled bundling content and graphic components as specifically defined by the work team meeting end users requirements The entire product development process is optimized becoming more agile, efficient and rapid

18 Benefits for Manufactures Manufacturers increase their competitiveness: Time-to-market enhanced Product developement cycle is shorten Costs cut Product development costs are reduced using the same HW for different vehicles Highly customized products A wide veriety of different products can be obtained changing only small parts of the system or simply reskinng graphic

19 Benefits for Final User Digital instrument clusters enhance and make unique end-users experience being: Customizable Leaving plenty of freedom to end users, allowing them to personalize the display by altering the color, wallpaper, or gauge layout Attractive Enhancing the appeal of a vehicle with eye-catching graphics and features Simple Combining ease of use to a clean interface, displaying only the information currently required by the driver Innovative Using the latest techniques for rapid model development and design
