CONTROL SYSTEM AND METHOD FOR A VEHICLE SYSTEM

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. -40-Date Recue/Date Received 2020-12-16 128 1/4 11 M¨D¨M loo- '.e... ...v 108 _________________________________ IT' __________ c¨ 102 c0 136 ____ 112 130-Z- ________________________ I 12314118 110 / 12 104-- / 122 132 122 122120 106 120 1 134 120 118 120 122 FIG. 1 c¨ 136 CONTROLLER j ________________________________________________________________ 138--,N_ Processor _________________________________________________________ Battery Regulator Unit 141 138--N_ Processor j Sensors 132 140-N_ Memory ______________________ 124 --N_ LoecItoer _________________ D Vehicle 134--) Characterization _____________ Element I _________________________ Trip 130-)Characterization _______________ Element FIG. 2 Date Recue/Date Received 2020-12-16 2/4 r142 Propulsion Subsystem r144 r148 r 150 Engine 147 Energy Storage Transmission Prime Device Mover r154 Electric Bus r122 r112 Axles Braking system FIG. 3 (-400 r402 r420 r404 Second Vehicle First Vehicle Second First Propulsion Subsystem Propulsion 424 Subsystem -408 First Engine y Second engine r426 First Prime y-410 Second Prime Mover Mover Controller 414- y-412 (-416 y-430 Second First First Transmission Transmission Axels Second Axels r418 -432 First Second Energy Storage Energy Storage Device Device -434 FIG. 4 Date Recue/Date Received 2020-12-16 3/4 c¨ 500 i-502 Determine Engine Operational Parameters i-504 Determine Energy Storage Device Operational Parameters i-506 Determine a Change in Life of an On-Board Energy Storage Device i-508 Determine a change in Fuel Usage of an Engine i-510 Generate a Trip Plan for a Trip of the Vehicle System i-512 Switch an Operation Mode of the Vehicle Subsystem FIG. 5 Date Recue/Date Received 2020-12-16 4/4 r 602 Inputs c¨ 600 .Train makeup .Track .Engine size > .Battery Capacity Penalty sweep curve .Fuel, Replacement costs -0 .3) A > N Constraints/Limits .Travel time, speed limits > 0(1 /11 .Tractive effort, effort rat
