Abstract

Systems and apparatuses include a controller including at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, causes the at least one processor to: receive data indicative of at least one of a current route or of a current performance of a vehicle; correlate at least one of the current route or the current performance to a control strategy; and determine at least one of a timing or a duration of an active regeneration event for an aftertreatment system based on the correlated control strategy.

First claim

What is claimed is:

1 . A system comprising:
a controller comprising at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, causes the at least one processor to perform operations comprising:
receive data indicative of at least one of a current route or of a current performance of a vehicle;
correlate at least one of the current route or the current performance to a control strategy; and
determine at least one of a timing or a duration of an active regeneration event for an aftertreatment system based on the correlated control strategy.

2 . The system of claim 1 , wherein the control strategy is developed using an advanced analysis of data collected from a plurality of vehicles.

3 . The system of claim 1 , wherein the timing of the active regeneration event includes skipping a previously planned regeneration event based on the correlated control strategy.

4 . The system of claim 1 , wherein the active regeneration event is a regeneration event for a diesel particulate filter (DPF).

5 . The system of claim 1 , wherein the determination of at least one of the timing or the duration is further based on a feed-forward loop with the control strategy and data indicative of at least one of the current route or of the current performance.

6 . The system of claim 1 , the operations further comprising:
determine a timing and amount of diesel exhaust fluid (DEF) usage based on the correlated control strategy, wherein the correlated control strategy comprises information regarding at least one of a temperature of a selective catalytic reduction (SCR) system, ammonia storage, or ammonia-to-NOx ratio (ANR).

7 . The system of claim 1 , the operations further comprising:
minimize at least one of an amount of system-out NOx or an amount of ammonia slip based on the correlated control strategy, wherein the correlated control strategy comprises information regarding at least one of a temperature of a selective catalytic reduction (SCR) system, ammonia storage, or ammonia-to-NOx ratio (ANR).

8 . The system of claim 1 , the operations further comprising:
activate at least one of a heater or a cylinder-deactivation (CDA) system based on the correlated control strategy.

9 . The system of claim 1 , wherein the determination is further based on current weather conditions.

10 . The system of claim 1 , wherein the controller is in substantially continuous communication with a remote computing system via a network, and
wherein the correlation to the control strategy is done over the network.

11 . A method for managing components of an aftertreatment system, the method comprising:
receive, by a controller, data indicative of at least one of a current route or of a current performance of a vehicle; correlate, by the controller, at least one of the current route or the current performance to a control strategy; and determine, by the controller, at least one of a timing or a duration of an active regeneration event for an aftertreatment system based on the correlated control strategy.

12 . The method of claim 11 , wherein the control strategy is developed using an advanced analysis of data collected from a plurality of vehicles.

13 . The method of claim 11 , wherein the timing of the active regeneration event includes skipping a previously planned regeneration event based on the correlated control strategy.

14 . The method of claim 11 , wherein the determination of at least one of the timing or the duration is further based on a feed-forward loop with the control strategy and data indicative of at least one of the current route or of the current performance.

15 . The method of claim 11 , further comprising:
determining a timing and amount of diesel exhaust fluid (DEF) usage based on the correlated control strategy, wherein the correlated control strategy comprises information regarding at least one of a temperature of a selective catalytic reduction (SCR) system or an ammonia-to-NOx ratio (ANR).

16 . The method of claim 11 , further comprising:
minimizing, by the controller, at least one of an amount of system-out NOx or an amount of ammonia slip based on the correlated control strategy, wherein the correlated control strategy comprises information regarding at least one of a temperature of a selective catalytic reduction (SCR) system, ammonia storage, or ammonia-to-NOx ratio (ANR).

17 . The method of claim 11 , further comprising:
activating, by the controller, at least one of a heater or a cylinder-deactivation (CDA) system based on the correlated control strategy.

18 . A system comprising:
a controller comprising at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
receive data indicative of at least one of a current route or of a current performance of a vehicle;
correlate at least one of the current route or the current performance to a control strategy; and
alter at least one of a timing or a duration of a passive regeneration event for an aftertreatment system based on the correlated control strategy using at least one of a heater or a cylinder deactivation (CDA) system.

19 . The system of claim 18 , wherein the at least one of the heater or the CDA system is activated to increase a target regeneration faster relative to an occurrence of the passive regeneration event by itself.

20 . The system of claim 18 , wherein the at least one of the heater or the CDA system is activated before an end of the passive regeneration event to maintain an elevated exhaust gas temperature.
