  • Patent number: 9278684
    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.

  • Patent number: 8918240
    Abstract: A method and system used to identify an optimal hybrid vehicle operating mode based on a variety of potential factors, and then recommend the optimal operating mode to the driver so that they can make an informed decision regarding their operating mode selection. In one embodiment, the method uses geographic-, vehicle- and/or environmental-related factors to establish one or more operating zones, monitors the location of the hybrid vehicle and determines when it is within one of the operating zones, and then determines an operating mode that is optimal for that particular operating zone.
