More Information
Summary:Described herein is a method of determining a current location speed-limit in a road-vehicle (1) speed-limit information system (2). One or more signals (3, 4) corresponding to respective candidate speed-limits for the current location are received. A parametrized heuristic algorithm with an associated cost function is applied (7) to decide which candidate speed-limit (3, 4), if any, that is applicable. If available for the current location, a cloud service (8) supplied estimated true speed-limit (9) and an associated confidence in this estimate is received. An online learning or a reinforcement learning method is used to, based on the cloud service (8) supplied estimated true speed-limit (9) and the associated confidence in that estimate, constantly fit (10) the heuristic's parametrization to, with a high confidence, reproduce the cloud service (8) supplied estimated true speed-limit (9). A speed-limit information signal (11) corresponding to the decision of the parametrized heuristic algorithm is output.
