Abstract: A vehicle is provided with a powertrain including an electric motor, an internal combustion engine, and a turbocharger. The vehicle further includes a controller programmed to apply a variable filter to engine torque commands that are responsive to driver demand. The filter affects commands having a rate of increase greater than a predetermined threshold such that corresponding rates of increase in both engine torque and turbocharger speed are limited to respective rates less than the maximum available levels in order to reduce a surge in engine output emissions. The controller additionally issues commands for motor torque such that overall powertrain torque satisfies the driver demand.

Abstract: A vehicle includes an engine having a crankshaft, a transmission having an input, and an electric machine mechanically coupled to the transmission input. The vehicle further includes a clutch configured to mechanically couple the electric machine and engine crankshaft, and at least one controller. The at least one controller, in response to an engine start condition and subsequent partial engagement of the clutch, outputs a torque command for the electric machine to increase the speed of the crankshaft to a speed of the electric machine before commanding fuel injection of the engine. The torque command is based on driver demanded torque and a change in speed of the crankshaft caused by changes in pressure to the clutch.

Abstract: A vehicle includes an engine having a crankshaft, a transmission having an input, and a torque converter mechanically coupled to the input. The vehicle further includes an electric machine mechanically coupled to the torque converter, a clutch configured to mechanically couple the electric machine and crankshaft, and one or more controllers. The one or more controllers are programmed to, in response to the transmission being in a drive or reverse gear and a speed of the vehicle being less than a predetermined value in an absence of driver demand, control the electric machine to achieve a target speed to cause the torque converter to output torque such that the speed of the vehicle approaches a generally constant speed less than or equal to the predetermined value when the vehicle is on a generally flat grade.

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 vehicle includes a starter motor, an engine having an output mechanically coupled to the starter motor, a transmission having an input, and an electric machine mechanically coupled to the transmission input. The vehicle further includes a clutch configured to mechanically couple the electric machine and the output of the engine, and at least one controller. The at least one controller is programmed to initiate an engine start based on driver demand. The controller is further configured to enable pressure to the clutch for the engine start if driver demand is less than a calibratable torque value or enable the starter motor for the engine start if the driver demand is greater than a calibratable torque value. The controller may lock the clutch to the output of the engine in response to the speed of the engine being approximately equal to the speed of the electric machine.

Abstract: A hybrid vehicle and method of control include an internal combustion engine and at least one traction motor operated such that engine speed is a function of vehicle speed and target engine power. Target engine power, in turn, is a function of target wheel torque, vehicle speed, and battery state of charge. Target wheel torque, in turn, is a function of vehicle speed and accelerator pedal position. In a select shift mode, these calculations are adjusted based on a virtual gear number which varies in response to driver activation of shift selectors. The adjustments result in decreased engine speed and decreased wheel torque when higher virtual gear number are selected for given accelerator pedal positions and vehicle speeds. The ratio of engine speed to vehicle speed is not necessarily constant when operating in select shift mode.

In one example, driver demand torque may be supplied to vehicle wheels via a hydraulic torque path and a friction torque path. Torque is distributed between the friction torque path and the hydraulic torque path in a way that ensures that driver demand torque is met and the friction torque path transfers torque up to its capacity.

Abstract: A system and method for controlling a hybrid electric vehicle powertrain having an engine defining one power source, and a traction motor and electrical storage device defining another power source include inhibiting a stopping and a starting of the engine based upon an unintended tip-out event and an unintended tip-in event, respectively. The total power demand and the available electric power are determined. The total power demand is filtered. The engine is prevented from being pulled-up or pulled-down based upon a difference between the total power demand and the filtered power demand being exceeding a threshold. However, if the difference exceeds the threshold, and if the available electric power exceeds the total power demand, then the engine is permitted to pull-up or pull-down.
