Architectural Issues

U. O. Sept. 1999

Vehicle to Infrastructure to Vehicle

Congestion / Accident warnings Warning to plan stop at traffic light Construction / Detour warning with alternate

route Driving speed to pace traffic / signals Input Intended Destination and Get:

– Estimated travel times– Best Route

Weather conditions / hazards

U. O. Sept. 1999

Potential Vehicle-to-Vehicle Areas Information

Driver Characterization – Aggressive, Slow, Unskilled or Erratic (potentially impaired)

Vehicle Speed & Direction (Location)– Estimate left turn & passing clearances

Advanced Warning– Intended maneuvers from vehicles out of visual contact

Emergency situations– High deceleration, ABS or Traction Control actuation

Emergency vehicles in the area Cross traffic approaching too fast to stop

U. O. Sept. 1999

Vehicle to Driver

Multi-sensory feedback methods Prioritization of feedback (reduce

confusion and make faster decisions) Early warning of danger approaching Hands-free communication Eyes-on-the-road communication

U. O. Sept. 1999

Driver-to-Vehicle

“Smart Card” in pocket– Unlocks/opens doors / trunk– Identifies driver and accommodates seats, mirrors,

entertainment system, etc.– Notes medical information (in case of emergency)

Voice Recognition Hands-Free Communication Driving Habits Monitored & Characterized

– Better able to anticipate hazards / problems
