    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 is provided that includes an engine, a reversible electric machine capable of generating and providing electric power, and a clutch for selectively engaging the engine to the electric machine. While the vehicle is traveling, an operator of the vehicle may release (“tip-out”) the accelerator pedal, indicating a desire for a reduction in speed and/or acceleration of the vehicle. If the clutch is engaged during the tip-out, the at least one controller is programmed to disengage the clutch and alter a commanded torque to the electric machine in response to the tip-out of the accelerator pedal to simulate compression braking of the engine. If the vehicle is operating in an electric-only mode of propulsion during the tip-out, and if a state-of-charge of the battery is relatively high, the controller is programmed to activate the engine and provide compression torque to the driveline in response to the tip-out.
