<p>A vehicle includes an engine and a particulate filter that is situated to filter particulates from the exhaust fluid. A controller is configured to implement a sequence of particulate filter regeneration techniques including a first technique during an engine start up condition, a second technique during a running engine idle condition, and a third technique during a driving condition. The controller is configured to determine whether particulate filter regeneration is desired, implement the first technique when particulate filter regeneration is desired, determine whether particulate filter regeneration is still desired after using the first technique, implement the second technique when regeneration is still desired after using the first technique, determine whether particulate filter regeneration is still desired after using the second technique, and implement the third technique when regeneration is still desired after using the second technique.</p> |
