A
system and method generate a trip plan for a trip of a vehicle
system along a
route. The usage of an engine during the trip is determined based on engine operational parameters,
energy storage device operational parameters, and one or more objectives of the trip desired to be achieved. The usage of the
energy storage device during the trip is also determined based on the engine operational parameters, the
energy storage device operational parameters, and the one or more objective, including when to charge or
discharge the energy storage device during the trip.
