Abstract: Responsive to a user request, a controller operates an engine of a vehicle while parked to charge a traction battery to a target state of charge that exceeds a maximum state of charge limit, used during drive of the vehicle by an electric machine, in advance of a predefined period of time.

Abstract: Methods and systems are provided for operating a driveline of a hybrid vehicle during conditions when a temperature of a motor/generator is increasing. In one example, a method is provided that adjusts engine speed as a function of motor/generator temperature while maintaining engine power output when driver demand wheel power is constant.

Abstract: A vehicle includes an engine, a continuously variable transmission including an input shaft coupled to the engine, an output shaft, an electric machine, and a gearing arrangement. The electric machine is configured to actuate the gearing arrangement to change a speed ratio between the input and output shafts. A controller is programmed to, responsive to a request to manually shift the transmission to one of a predetermined number of virtual discrete speed ratios and the engine being OFF, command starting of the engine regardless of a driver-demand torque and operate the electric machine to shift the transmission to the one of the speed ratios.

Abstract: This disclosure relates to an electrified vehicle having a control strategy for managing battery and cabin cooling. A corresponding method is also disclosed. An example electrified vehicle includes a cabin thermal management system configured to thermally condition a cabin of the electrified vehicle. The cabin thermal management system includes a compressor. The vehicle further includes a battery thermal management system configured to thermally condition a battery of the electrified vehicle, and a controller configured issue an instruction to reduce the speed of the compressor based, at least in part, on a speed of the electrified vehicle and a temperature of the battery.

Abstract: A method for operating a vehicle that may be automatically stopped and started is described. In one example, the method includes inhibiting automatic engine stopping in response to a temperature of an emissions device exceeding a threshold temperature. In addition, additional actions may be taken to reduce the temperature of the emissions device when automatic engine stopping is inhibited.

Abstract: Methods and systems are provided for operating a continuously variable transmission (CVT) of a driveline of a vehicle during a request for engine compression braking. In one example, a method may include, responsive to an engine compression braking request, operating a CVT via a controller to adjust engine speed according to an engine speed-to-vehicle speed profile selected based on a power-based target engine speed for the engine compression braking request. The power-based target engine speed may vary continuously with driver demanded power and a battery charge power limit of the vehicle.

Abstract: Methods and systems are provided for enhancing reverse driving torque in a powersplit hybrid electric vehicle powertrain. In one example, a method may include accelerating an engine via a generator functioning as a motor, any number of times, to provide an engine braking torque that may increase a reverse driving torque to enable the vehicle to be propelled in reverse at a vehicle speed above a threshold vehicle speed. In this way, reverse gradability may be improved and customer satisfaction increased.
