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.
Abstract:
A method can be used to control a hybrid vehicle and includes the following steps: (a) receiving, via a control module, an input; (b) determining, via the control module, whether the hybrid vehicle is traveling on a highway based, at least in part, on a vehicle speed and an output torque request; (c) commanding, via the control module, the hybrid powertrain to switch from a charge-depletion mode to a blended mode if the hybrid vehicle is traveling on a highway; and (d) commanding, via the control module, the hybrid powertrain to use energy from the energy storage device via the electric motor-generator so as to maintain a substantially constant target state of charge (SOC) discharge rate.

Abstract:
An operating system for a vehicle having an electric vehicle (EV) drivetrain and a plurality of electrically-powered accessories is described. A controller determines, via a navigation system, a target off-road trail segment, and characterizes the subject vehicle, ambient conditions, and the target off-road trail segment to determine an estimated consumption of electric energy for the vehicle to operate over the target off-road trail segment. The EV drivetrain and the electrically-powered accessories are controlled during operation of the vehicle on the off-road trail segment based upon the estimated consumption of electric energy for the subject vehicle. This is done to minimize a likelihood of a low SOC event for the DC power source for the trail segment and to avoid a low battery state at a location that is distal from a charging station.

Abstract:
A power panel closure system may include a moveable panel and a panel driver energizable in a first direction associated with movement of the panel toward closing and energizable in a second direction associated with movement of the panel toward opening. A panel latch may have a primary latch state wherein the panel is held in a closed position. A control module may perform a panel opening sequence including energizing the panel driver in the first direction while the panel is being held in the closed position by the panel latch in the primary latch state, releasing the panel latch from the primary latch state, and energizing the panel driver in the second direction.

Abstract:
A vehicle system includes an electric motor, an internal combustion engine, and a heating system configured to transfer heat from the internal combustion engine to a passenger compartment of the vehicle. The system includes a controller configured to operate the electric motor and the internal combustion engine according to one of a plurality of drive cycle profiles. The controller selects the drive cycle profile based on an ambient temperature. The drive cycle profiles include a first drive cycle profile that commands power from the electric motor until the battery system reaches a predetermined state of charge and subsequently commands power from the internal combustion engine and a second drive cycle profile that commands power from the internal combustion engine and subsequently commands power from the electric motor.
