VII Driver Assistance System

This video shows a field test of our driver assistance system developed at California PATH, UC-Berkeley. This system integrates GPS, digital map, on-board sensors and wireless communication to access road-related information and estimate vehicle states and thereby provides a number of in-vehicle signages and speed advisory or warnings, such as stop sign, (T-)intersection, curve overspeed, pedestrian crossing,lane-departure, and wrong way warnings etc. More functions will be incorporated into current system platform using V-V or V-I communication. The feature of the system is the enhanced GPS-based positioning through novel sensor fusion techniques to deal with the frequent GPS blockage, outage and (reflection) multipath errors in urban canyon. Also, the real-time map update via vehicle-infrastructure communication is another feature, which enables the incorporation of dynamic road information into system computation.
Besides the aforementioned warning functions, automatic braking and steering controls are likely to be incorporated into this system for collision avoidance. This is one of our future research topics.
