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.

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 traffic controller includes a controller configured to reject a request and issue a speed requirement based on a priority to cause a speed of a one of a plurality of vehicles to be within a speed band before entering a road. The rejection is responsive to receiving the speed request from the one approaching the road having priority less than a predetermined threshold and outside of a speed band and a predetermined acceleration band of vehicles on the road.

Abstract: A hybrid powertrain includes a traction battery and a controller. The controller is programmed to, responsive to a current vehicle speed exceeding a first threshold, reduce a parameter indicative of state of charge (SOC) of the battery by an offset amount that varies with an amount of predicted distance for which a predicted vehicle speed profile is less than a second threshold to prompt charging of the battery to increased SOC values.

Abstract: A hybrid vehicle control system and method include a controller programmed to, while a transmission is in PARK or NEUTRAL, start an engine, close a disconnect clutch selectively coupling the engine to an electric machine, and control the electric machine to charge a traction battery in response to the accelerator pedal position exceeding an idle position and being less than a threshold. The controller controls transmission impeller speed in response to accelerator pedal position exceeding the threshold to allow revving the engine in response to accelerator pedal. A method for controlling a hybrid vehicle includes starting an engine, closing a clutch between the engine and an electric machine, and controlling the engine and the electric machine to either: i) charge a traction battery or ii) rev the engine based on accelerator pedal position relative to a threshold above an idle position while the transmission is in PARK or NEUTRAL.

Abstract: A vehicle includes an engine having a crankshaft, a transmission, an electric machine, and at least one controller. The transmission includes a torque converter having a turbine fixed to a turbine shaft that is driveably connected to driven wheels of the vehicle. The torque converter includes an impeller and a bypass clutch configured to selectively lock the impeller and the turbine relative to each other. The electric machine includes a rotor selectively coupled to the crankshaft via a disconnect clutch and fixed to the impeller. The at least one controller is configured to generate a first torque command for the electric machine that defines a magnitude equal to driver-demanded torque while the bypass clutch is locked. The controller is further configured to, in response to a reduction in fluid pressure supplied to the bypass clutch, generate a second torque command for the electric machine that defines a magnitude equal to driver-demanded torque plus impeller inertia torque.

Abstract: A shift strategy is provided for a hybrid electric vehicle to cause a speed of a motor to approach a target motor speed to increase fuel economy for an engine operating in a hybrid drive mode. A controller shifts the transmission according to a magnitude of a driver torque demand, the current rotor or impeller speed, and whether the motor is consuming or producing current. The controller shifts the transmission according to one shift schedule when the motor is motoring, and according to another shift schedule when the motor is generating power.

Abstract: A system and method for controlling a transmission gear shift in a vehicle having a driveline and an electric motor operable to output torque to the driveline includes applying a negative motor torque to the driveline to reduce driveline oscillations resulting from the transmission gear shift. The negative motor torque is based on vehicle conditions occurring after the transmission gear shift has begun and before the transmission gear shift is complete.
