Abstract

A method is provided for estimating a propulsion-related operating parameter of a vehicle for a road segment, and for determining routes based on the estimate. The method may be employed, for example, in a vehicle navigation system. In one example method, at least one operating parameter of the vehicle is estimated for the road segment based on information corresponding to the road segment. The propulsion-related operating parameter is estimated for the road segment using the at least one estimated operating parameter and at least one vehicle specific parameter. The at least one vehicle specific parameter is determined by acquiring driving data to determine a plurality of vehicle operating parameters while the vehicle is in operation. At least two of the determined vehicle operating parameters are used in a predetermined relationship that includes the at least one vehicle specific parameter. The at least one vehicle specific parameter is then determined from the driving data for the at least two vehicle operating parameters and the relationship.
