    Abstract: A method of controlling a ground vehicle includes providing the vehicle with a first sensor configured to detect a vehicle position, a second sensor configured to detect a driven path of the vehicle, and a controller. The method also includes obtaining, via the first sensor, a plurality of vehicle position coordinates during a time interval of a drive cycle, and calculating, via the controller, a first path curvature parameter based on the plurality of vehicle position coordinates. The method additionally includes obtaining, via the second sensor, a second path curvature parameter based on the driven path during the time interval. The method further includes comparing, via the controller, the first path curvature parameter to the second path curvature parameter, and in response to a difference between the second path curvature and the first path curvature exceeding a threshold, automatically operating the controller according to a diagnostic mode.

    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.
