Abstract
Described herein is a method of determining a current location speed-limit in a road-vehicle () speed-limit information system (). One or more signals () corresponding to respective candidate speed-limits for the current location are received. A parametrized heuristic algorithm with an associated cost function is applied () to decide which candidate speed-limit (), if any, that is applicable. If available for the current location, a cloud service () supplied estimated true speed-limit () 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 () supplied estimated true speed-limit () and the associated confidence in that estimate, constantly fit () the heuristic's parametrization to, with a high confidence, reproduce the cloud service () supplied estimated true speed-limit (). A speed-limit information signal () corresponding to the decision of the parametrized heuristic algorithm is output.
