The Computer Science Team replaced the center stack system of the hybrid vehicle. In addition to maintaining original functionality, the team added a diagnostic display. * BEFORE AFTER – GUI touch screen MAIN MENU RADIO Physical radio control knobs and buttons CLIMATE CONTROL DIAGNOSTICS Physical HVAC knobs and buttons DESIGN components System architecture Model/View/Controller Architecture Qt Modeling Language (QML) Controller Area Network (CAN) signals Freescale Board: computer that runs code View Controller Model Simulator.h Simulator.cpp Diagnostics.qml ACWindow.qml Radio.qml Home.qml CAN-SEND.h CAN-RECEIVE.h Presentation Touch screen Linux Kernel CAN BUS Freescale I.MX6 Board Car Advice for Future Developers The CS team learned firsthand about the difficulties of integrating software with hardware > Test on actual car as soon as possible to expose communication problems early > Make some individual responsible for successful integration of hardware and software > Learn the limitations of running on a board vs. a standard computer
