Title: Control system and method for a vehicle system
Inventor: SEENUMANI GAYATHRI
IPC: B60W20/00
Filed: 2020-12-16
Abstract: ABSTRACT 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.
