Abstract (en)
[origin: EP2017807A1] The method involves establishing a plausible speed limit associated to a confidence index (IC1) by a navigation system (101). Information (151) comprising the limit and index is constituted. A probable speed limit associated to another confidence index (IC2) is established by an image processing system (102). Information (152) comprising the probable limit and latter index is constituted. A current speed limit (153) is determined from the information and by considering the indexes. The indexes are respectively developed from parameters e.g. road type and shadow factor on considered image. An independent claim is also included for a system for automatically determining speed limits on a road or point borrowed by a motor vehicle.
