Abstract

Systems and methods for analyzing acceleration as a road segment characteristic in a vehicle are provided for determining information about a route including for example, the estimated fuel consumption of the route. An example of a system includes a data storage medium for storing map data having road segments, a bus interface to a data bus for receiving measured values of a velocity or an acceleration from a velocity or acceleration sensor, a position data receiver configured to receive position data for determining a current position, and a system controller. The system controller is configured to identify a road segment associated with the current position. The system controller retrieves parameters of a probability distribution of acceleration associated with the identified road segment from the data storage medium. Updated parameters of the probability distribution of acceleration are determined from the measured values of the velocity or acceleration.
