Abstract

Method and apparatus for maintaining a speed of a vehicle within a target speed range. A plurality of coasting profiles are generated for the vehicle, each having an initial speed and a starting point on a predicted vehicle path. Each coasting profile represents a predicted vehicle speed over a time and/or distance from the starting point and is generated based on a geometry of at least a portion of the predicted vehicle path. At least one of the coasting profiles that maintains the speed of the vehicle within the target speed range is identified. A prime mover of the vehicle is controlled to place the vehicle into a coasting mode in accordance with the at least one identified coasting profile. Alternatively, feedback is provided to a user to place the vehicle into a coasting mode, such that the vehicle will coast in accordance with the at least one identified coasting profile.
