Abstract

The present disclosure generally relates to a system and methods for managing and controlling emissions produced by a vehicle and/or powertrain which includes one or more power sources selected from a fuel cell, a fuel cell stack, a battery, and combinations thereof, a processor, one or more inputs, a controller, and one or more emission control devices.

First claim

What is claimed is:

1. A method for managing emissions produced by a vehicle and/or powertrain, the method comprising:
receiving one or more inputs into a processor in the vehicle and/or powertrain,
generating an emission criteria management strategy by the processor that communicates with a controller and one or more power sources, wherein the one or more power sources are selected from a fuel cell, a fuel cell stack, a battery, and combinations thereof,
implementing the emission criteria management strategy by the controller that communicates with the one or more power sources and one or more emission control devices, wherein implementing the emission criteria management strategy includes moving a portion of the emissions comprising hydrogen into an internal tank for storage before the vehicle enters a zone or a restricted region,
controlling the power output of the one or more power sources, and
managing the emissions from the one or more emission control devices.

2. The method for managing emissions produced by a vehicle and/or powertrain of claim 1 , wherein the emission criteria management strategy is generated and implemented before the vehicle and/or powertrain enters the zone or the restricted region.

3. The method for managing emissions produced by a vehicle and/or powertrain of claim 1 , wherein the vehicle and/or powertrain comprises a marine vessel, a train, a bus, or a mining equipment.

4. The method for managing emissions produced by a vehicle and/or powertrain of claim 1 , wherein the vehicle and/or powertrain is used on waterways, highways, off-highways or off-road, underground, or in high altitude regions.

5. The method for managing emissions produced by a vehicle and/or powertrain of claim 1 , wherein implementing the emission criteria management strategy further comprises diluting the hydrogen in the emissions purging the hydrogen from the vehicle and/or powertrain, or decreasing the hydrogen content in the emissions by changing the one or more power sources used in the vehicle and/or powertrain.

6. The method for managing emission produced by a vehicle and/or powertrain of claim 2 , wherein generating the emission criteria management strategy further comprises identifying the zone or the restricted region and identifying a primary power source to generate power output in the zone or the restricted region.

7. A method for controlling emissions produced by a vehicle and/or powertrain, the method comprising:
receiving one or more inputs into a processor in the vehicle and/or powertrain,
generating an emission criteria management strategy by the processor that communicates with one or more power sources and a controller,
identifying at least one primary power source selected from the one or more power sources, wherein the one or more power sources are selected from a fuel cell, a fuel cell stack, a battery, and combinations thereof,
implementing the emission criteria management strategy by the controller that communicates with the one or more power sources and one or more emission control devices, wherein implementing the emission criteria management strategy comprises moving a portion of the emissions into an internal tank for storage before the vehicle enters a zone or a restricted region,
engaging the at least one primary power source to produce a power output required by the vehicle and/or powertrain, and
controlling the power output of the one or more power sources and the emissions from the one or more emission control devices.

8. The method for controlling emissions produced by a vehicle and/or powertrain claim 7 , wherein the emission criteria management strategy is generated and implemented before the vehicle and/or powertrain enters the zone or the restricted region.

9. The method for controlling emissions produced by a vehicle and/or powertrain of claim 7 , wherein the vehicle and/or powertrain comprises a marine vessel, a train, a bus, or a mining equipment.

10. The method for controlling emissions produced by a vehicle and/or powertrain of claim 7 , wherein the vehicle and/or powertrain is used on waterways, highways, off-highways or off-road, underground, or in high altitude regions.

11. The method for controlling emissions produced by a vehicle and/or powertrain of claim 7 , wherein implementing the emission criteria management strategy further comprises diluting the hydrogen in the emissions, purging the hydrogen from the vehicle and/or powertrain, or decreasing the hydrogen content in the emissions by changing the one or more power source used in the vehicle and/or powertrain.

12. The method for controlling emission produced by a vehicle and/or powertrain of claim 8 , wherein generating the emission criteria management strategy further comprises identifying the zone or the restricted region and identifying a primary power source to generate power output in the one or the restricted region.

13. A system for managing emissions produced by a vehicle and/or powertrain, comprising:
one or more power sources,
a processor that generates an emission criteria management strategy based on one or more inputs and the one or more power sources, wherein the one or more power sources are selected from a fuel cell, a fuel cell stack, a battery, and combinations thereof,
an internal tank, wherein a portion of the emissions is moved into the internal tank for storage before the vehicle enters a zone or a restricted region based on the emission criteria management strategy, and
a controller that implements the emission criteria management strategy in one or more power sources and one or more emission control devices in the vehicle and/or powertrain.

14. The system for managing emissions produced by a vehicle and/or powertrain of claim 13 , wherein the one or more power sources comprises at least one primary power source for the vehicle and/or powertrain.

15. The system for managing emissions produced by a vehicle and/or powertrain of claim 14 , wherein the one or more emission control devices comprises at least one sensor for the vehicle and/or powertrain.

16. The system for managing emissions produced by a vehicle and/or powertrain of claim 13 , wherein the system is employed when the vehicle and/or powertrain enters the zone or the restricted region.

17. The system for managing emissions produced by a vehicle and/or powertrain of claim 13 , wherein the vehicle and/or powertrain comprises a marine vessel, a train, a bus, or a mining equipment.

18. The system for managing emissions produced by a vehicle and/or powertrain of claim 13 , wherein the vehicle and/or powertrain is used on waterways, highways, off-highways or off-road, underground, or in high altitude regions.

19. The system for managing emissions produced by a vehicle and/or powertrain of claim 13 , wherein the one or more emission control devices comprises at least one storage tank for the vehicle and/or powertrain.

20. The system for managing emissions produced by a vehicle and/or powertrain of claim 16 , wherein generating the emission criteria management strategy further comprises identifying the zone or the restricted region and identifying a primary power source to generate power output in the zone or the restricted region.
