Next Generation Vehicle Positioning in GPS-Degraded Environments for Vehicle Safety and Automation Systems

By combining three technology areas, the research seeks to develop an integrated system that exploits the strengths of each technique. First, terrain-based localization (based on precise measurements of vehicle pitch and roll, combined with wheel odometry) can be readily used to find the vehicle's absolute longitudinal position within a pre-mapped highway segment - compensating for drift which occurs in dead-reckoning systems in long longitudinal stretches of road. Secondly, visual odometry keys upon visual landmarks at a detailed level to correlate position to a (visually) premapped road segment to find vehicle position along the roadway. The third technology approach relies on radio frequency (RF) ranging based on dedicated short range communication (DSRC) radio technology.
