Multisensory correlation of traffic lanes

摘要

To increase convenience and safety in vehicles, sensor systems for environmental sensing which feature an intelligent scene interpretation are increasingly gaining importance. To determine the position of a motor vehicle with respect to the traffic lane, the data from a digital road map coupled with a navigation system is fused with the data delivered by a distance-resolving sensor. In this context, the signature and the distance-related variation of the received signal of the distance-resolving sensor are evaluated for determining the distance from the road edge. The advantage of the present invention ensues from the possibility for a vehicle to autonomously determine its instantaneous position with respect to the traffic lane, without falling back on a stationary traffic infrastructure (marking lines reflectors).
