Abstract

A method for controlling a regeneration procedure in an exhaust system after treatment device in a vehicle, the method comprising: determining a location of the vehicle, obtaining data related to the location, determining, based on the data related to the location a probability of completing the regeneration procedure on the vehicle at said determined location, controlling the vehicle to perform the regeneration procedure in dependence on the probability of completing the regeneration procedure.

First claim

The invention claimed is:

1. A method for controlling a regeneration procedure in an exhaust system aftertreatment device in a vehicle, the method comprising:
determining a location of the vehicle;
obtaining data related to the location of the vehicle from a remote server;
determining, based on the data related to the location, a probability of completing the regeneration procedure on the vehicle at said determined location; and
controlling the vehicle to perform the regeneration procedure based at least in part on the probability of completing the regeneration procedure;
wherein the data obtained from the remote server comprises a probability of the regeneration procedure on the vehicle completing successfully based on historical data comprising past regeneration data at the determined location.

2. The method as claimed in claim 1 , further comprising transmitting the location of the vehicle to the remote server after the regeneration procedure on the vehicle has ended.

3. The method as claimed in claim 2 , further comprising transmitting vehicle parameters to the remote server after the regeneration procedure on the vehicle has ended, the vehicle parameters including at least one selected from a group consisting of:
the outcome of the regeneration procedure; the degradation of the aftertreatment device;
the direction of travel; the type of vehicle; and a time stamp.

4. The method as claimed in claim 2 , further comprising monitoring the condition of the exhaust system aftertreatment device prior to transmitting the location of the vehicle to the remote server.

5. The method as claimed in claim 1 , further comprising transmitting the location of the vehicle to the remote server prior to initiating the regeneration procedure.

6. The method as claimed in claim 5 , further comprising transmitting vehicle parameters to the remote server prior to initiating the regeneration procedure, the vehicle parameters including at least one selected from a group consisting of: the direction of travel; the degradation of the aftertreatment device; the type of vehicle; a time stamp; and road traffic conditions.

7. The method of claim 1 , further comprising:
determining a predicted destination for the vehicle; and
determining the probability of completing the regeneration procedure on the vehicle at said location based at least in part on the predicted destination.

8. The method of claim 1 , further comprising:
determining a predicted route for the vehicle; and
determining the probability of completing the regeneration procedure on the vehicle at said location based at least in part on the predicted route.

9. A control system for controlling a regeneration procedure in an exhaust system aftertreatment device on a vehicle, the control system comprising:
a positioning module configured to determine a location of the vehicle; and
a determining module configured to obtain data from a remote server relating to the location of the vehicle and to determine a probability of completing the regeneration procedure on the vehicle at said location based on the obtained data;
wherein the control system initiates the regeneration procedure on the vehicle based at least in part on the probability of completing the action; and
wherein the data obtained from the remote server comprises a probability of the regeneration procedure on the vehicle completing successfully based on historical data comprising past regeneration data at the determined location.

10. The control system of claim 9 , wherein the control system is further configured to transmit the vehicle location to the remote server at the end of a regeneration procedure.

11. The control system of claim 10 , wherein the control system is further configured to transmit vehicle parameters to the remote server at the end of a regeneration procedure, the vehicle parameters including at least one selected from a group consisting of: the outcome of the regeneration procedure; the degradation of the aftertreatment device; the direction of travel; the type of vehicle; and a time stamp.

12. The control system of claim 9 , wherein the control system is further configured to transmit the vehicle location to the remote server prior to initiating a regeneration procedure.

13. The control system of claim 12 , wherein the control system is further configured to transmit vehicle parameters to the remote server prior to initiating a regeneration procedure, the vehicle parameters including at least one selected from a group consisting of: the degradation of the aftertreatment device; the direction of travel; the type of vehicle; a time stamp; and road traffic conditions.

14. The control system of claim 9 , wherein the control system is further configured to determine a predicted destination for the vehicle, and also to determine the probability of completing the regeneration procedure on the vehicle at said location based at least in part on the predicted destination.

15. A vehicle comprising a control system according to claim 9 .
