Abstract: A hybrid vehicle includes an engine and an electric machine selectively coupled to the engine via a clutch. The engine, electric machine, and clutch are arranged along a common axis. At least one controller is programmed to execute various commands when the vehicle is in park or neutral and the accelerator pedal of the vehicle is depressed. This enhances perceived vehicle reactions in response to accelerator pedal movement. To do so, the controller is programmed to control a rate of speed increase of the electric machine based on a rate of the depression of the accelerator pedal (e.g., “speed control”). Furthermore, the torque output of the engine is controlled to a target value irrespective of engine speed and engine torque is converted into electric energy via the electric machine (e.g., “torque control”). The rate of speed increase of the electric machine is altered when the engine is started.

Abstract: A vehicle is provided with a powertrain including a battery-powered electric motor, an internal combustion engine, a transmission, and a powertrain controller. The controller is programmed to permit an upshift of a transmission gear ratio while a powertrain torque demand is less than a forecasted available powertrain torque sustainable over a predetermined upcoming duration of time. The controller is also programmed to inhibit an upshift while the torque demand exceeds the forecasted available powertrain torque to reduce successive gear shifts. The controller may be further programmed to, in response to battery a state of charge being less than a threshold, reduce the forecasted available powertrain torque by an amount sufficient to provide a recharge to a battery. The controller may be further still programmed to reduce the forecasted available powertrain torque by an amount sufficient to restart the engine while the powertrain is operating in an engine-off traction mode.

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.

The starter-generator is coupled to the engine and is configured to adjust engine speed during an engine start-up event. The controller is programmed to, in response to engine speed increasing towards a target speed during an engine start-up event, generate a target drag torque with the starter-generator to reduce overshoot of the target engine speed.

Abstract: A vehicle includes a hybrid powertrain with a motor/generator electrically coupled to a high-voltage bus to provide propulsion. The vehicle also includes an integrated starter/generator electrically copulated to a low-voltage bus and configured to start the engine. A vehicle power system includes a power converter electrically coupled between the high-voltage bus and the low-voltage bus. During engine start events, operation of the integrated starter/generator is coordinated with operation of the power converter to reduce voltage sag on the low-voltage bus. An increase rate of current supplied to the integrated starter/generator is limited such that a current output of the power converter does not saturate at a maximum current output for a period of time after initiating the engine start event.

Abstract: A vehicle includes an engine, a motor selectively coupled to the engine, a transmission selectively coupled to the motor, and a controller. The motor is able to operate as a motor (to provide torque to the transmission) and a generator (to charge a battery). In one mode, the controller can command the engine to both propel the vehicle and provide torque to the motor to charge the battery. The controller estimates the maximum available engine torque in the current gear and maintains the vehicle in the current gear of the transmission. And, the controller commands the motor to charge the battery by a magnitude based on the difference between driver demanded torque and an estimated maximum available engine torque in a current gear of the transmission. This allows the engine to operate at (or near) its maximum torque output to fulfill driver demands and charge the battery while inhibiting downshifting.
