摘要

Method and apparatus for controlling a prime mover of a vehicle. A target speed that must be reached by the vehicle at a target position 120 on a current path of the vehicle is determined 112. At least one coasting profile 126 is estimated 114 for at least part of the vehicle path before the target position. The coasting profile is estimated at least partly based on a geometry (such as elevation) of the vehicle path. The coasting profile that meets a predetermined coasting requirement is determined 116. A coasting signal is output based on the determined coasting profile which can be placing the vehicle into a coasting mode based on the at least one determined coasting profile 117. Alternatively, based on the coasting signal, feedback is provided to a vehicle user to place the vehicle into a coasting mode 119, such that the vehicle if placed in the coasting mode by the user will coast in accordance with the at least one identified coasting profile.
