New GNSS-based Approaches for Advanced Driver Assistance Systems

The enhancement of road safety and traffic efficiency are the focus of many endeavors in science, economy and politics. A traditional approach is to increase vehicle safety by advanced and intelligent onboard systems using high developed sensors for the monitoring of the vehicle’s surrounding. However, these technologies are vehicle-autonomous solutions that only consider information coming from onboard sensors. These sensors are normally based on optical, ultra-sonic, radar or video camera systems and can only detect other vehicles or other objects along a line-of-sight up to the next obstacle. The view beyond a truck cruising just in front of the vehicle, for example, is not possible. New approaches are now dealing with co-operative technologies that enable the exchange of important information between vehicles and infrastructures for updated traffic data acquisition, recognition of traffic congestion due to accidents or other sudden incidents, local dynamic map data updates and driver warning. One key technology within such co-operative systems is the highly precise relative positioning between vehicles and the monitoring of the broader vehicle environment using ad-hoc data networks. These technologies can be primarily based on satellite systems like GPS or GALILEO supplemented by other onboard sensor data, whereby unprocessed sensor data and satellite pseudo range information will be exchanged between the vehicles within a dedicated radio range. These data, when compared with the onboard data, will finally enable the creation of virtual images of a vehicle’s surrounding using special microscopic traffic modelling algorithms. Future applications are road safety and Advanced Driver Assistance Systems (ADAS).
