Systems and methods for particulate filter regeneration

An engine method, comprising:

• in response to an operator destination selection indicated via a display of a vehicle;
• estimating an exhaust particulate filter soot load via an exhaust pressure sensor;
• determining a current location of the vehicle via a navigation system;
• retrieving one or more routes from the current location to a destination from a database via an electronic controller;
• ranking, via the controller, the one or more routes based on each of a particulate filter regeneration efficiency, fuel efficiency, and time of travel of each route;
• and
• displaying to the operator, via a user interface, the one or more routes to the selected destination in order of their rank.

A vehicle method, comprising:

• in response to a destination for a drive cycle not being indicated by an operator;
• determining a current location of a vehicle via a navigation system;
• retrieving a driving history of the operator from a database via an electronic controller;
• predicting a destination based on the driving history via the controller;
• dynamically updating selection of one or more upcoming route segments based on the current location of the vehicle relative to the predicted destination via the controller;
• ranking, via the controller, the one or more upcoming route segments based on each of a corresponding particulate filter regeneration efficiency, a fuel efficiency, and a time of travel;
• and
• displaying to the operator, via a user interface, the one or more upcoming route segments to the predicted destination, hierarchically in order of their rank.
