Abstract: A hybrid vehicle has an engine, an electric machine connected to the engine by an upstream clutch, a transmission gearbox connected to the electric machine by a downstream clutch, and a controller. The controller is configured to, in response to a commanded upshift of the gearbox, modulate a pressure of the upstream clutch. A method for controlling a vehicle includes, in response to a commanded upshift of a gearbox, controlling an upstream clutch to a first nonzero speed differential corresponding to a first inertia connected to and upstream of the gearbox to reduce inertia torque during the upshift. A method for controlling a vehicle includes, in response to a commanded upshift of a gearbox when the vehicle is beyond an electrical limit and a fast path torque reduction limit, slipping an upstream clutch and reducing torque outputs of an engine and an electric machine.

Abstract: A vehicle includes an engine, an electric machine, a battery, and at least one controller. The vehicle may further comprise a port for supplying power to a load external to the vehicle. The controller is programmed to operate the engine at a power level based on a difference between a battery voltage and a reference voltage such that a power output by the electric machine reduces the difference. The power level may define an engine operating point that minimizes fuel consumption. The operating point may be an engine torque and an engine speed. The power level may be further based on a state of charge of the battery. The electric machine may be operated to cause the engine to rotate at an engine speed corresponding to the selected power level. The difference may be caused by varying power drawn by a load external to the vehicle.

Abstract: A system and method for controlling a vehicle powertrain is provided. The system and method sets a required transmission input torque during a transient event. A required traction motor torque and a required engine torque, in combination, are set to fulfill the required transmission input torque. The system and method includes estimates an actual engine torque during a delay in providing the required engine torque during the transient event. A transient traction motor torque is commanded based on a difference between the actual engine torque and the required transmission input torque. The commanded transient motor torque compensates for the delay in providing the required engine torque in order to prevent torque disturbances during the transient event.

Abstract: A power system includes a primary bus connected to a traction battery, a secondary bus connected to an auxiliary battery, a power converter between the traction and auxiliary batteries, and a controller. The controller commands the power converter to increase a magnitude of current output to the secondary bus when an amount of charge current received by the traction battery exceeds a first amount threshold and commands the power converter to decrease the magnitude when an amount of charge current received by the auxiliary battery exceeds a second amount threshold.
