Automotive Applications of Display Systems and Human-Machine Interfaces using a Dash-Mounted Touch Screen Computer March 09, 2010 • Assim Addous • Sam Coogan • Santiago Hässig • Martin Perry
EcoCAT Overview • Automotive Human-Machine Interface (AHMI) to display vehicle information to driver • Modern vehicles contain wealth of disparate data • OEMs and car enthusiasts seek a consolidating interface • Must be below $1,200 to be competitively priced as vehicle upgrade package
Design Objectives • Real-time data • Fuel efficiency • Motor & engine operating points • Emissions composition • Historical data • Projected mileage on current drive cycle • Fuel saved • Diagnostic data • Low fuel • Engine overheating
GUI Content • 7” touch screen • Windows XP platform • LabVIEW 8.6 GUI
Current Status • Touch screen enabled computer that communicates with the CAN controller • CAN hub has been assembled • Rudimentary GUI developed on LabVIEW
EcoCAT System Overview HMI Computer parses USB data CAN Controller reads in signals from HUB
Temperature Control • Vehicle interior can reach temperatures of up to 120°F • The HMI Computer operates safely without a fan in environments under 95°F
Power On/Off Handling • Power off • Computer shutdown sequence triggered by vehicle signal indicating ignition off state • Initiate proper shutdown of operating system • Turn off power to the computer and monitor • Power on • Startup triggered by key position • Initiate operating system and LabVIEW
