Abstract
A method for controlling a hybrid vehicle includes the following: (a) receiving route data regarding a desired trip; (b) determining a load distribution along the desired trip based on the route data; (c) determining a load threshold based on the load distribution along the desired trip; (d) determining a charge depleting operating threshold based on a state of charge of the energy storage device; (e) commanding the powertrain to shift from a charge-depleting mode to a charge-sustaining mode when a load of the hybrid vehicle is equal to or greater than the load threshold; and (f) commanding the powertrain to shift from the charge-sustaining mode to the charge-depleting mode when the hybrid vehicle has traveled a distance that is greater than or equal to the charge-depleting operating threshold since the powertrain shifted from the charge-depleting mode to the charge-sustaining mode.
