Abstract: A controller is configured to respond to an engine start command, operate the engine to produce excess torque beyond a demand torque, and in response to engine speed achieving a threshold, operate the starter-generator to load the engine to consume the excess torque and drive the engine speed toward an electric machine speed, and engage a clutch to couple the engine and an electric machine.

Abstract: A control system for a modular hybrid electric vehicle operates an internal combustion engine at a torque level above the driver demanded torque improving the engine's efficiency. A traction motor driveably connected to the engine is operated at a torque level such that the combined torque satisfies the driver demand. The traction motor torque is limited to avoid inefficient combinations of speed and torque at which the motor is inefficient. During idle operation, the traction motor is operated at a torque determined from a battery state of charge and the engine is operated to maintain a predetermined speed. If the engine speed drops below a threshold, motor torque is adjusted to reduce the load on the engine to avoid stalling.

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 hybrid electric vehicle has a powertrain including an internal combustion engine, an electric machine, and a transmission coupled to controller(s) that control torque disturbances arising from changing output torques of the engine, electric machine, and transmission. A torque disturbance threshold is adjusted for driver comfort, and is used to respond to torque demand signals from the vehicle systems, including a battery charging subsystem, and a driver. The controller(s) respond to battery charge and driver demand torque signals, among others, and adjust engine and electric machine torque at a controlled rate and magnitude, using charge-torque-slew-rate, charge-torque, and other limits. Battery charging is similarly managed. The slew-rate, charge-torque, and other limits are adjusted as the torque disturbance threshold changes in response to changing performance of vehicle components, which thereby controls torque disturbances to be lower than the torque disturbance threshold for a plurality of engine, electric machine, and transmission operating conditions.

Abstract: Systems and methods for improving operation of a driveline disconnect clutch for a hybrid vehicle shifting are presented. In one example, pressure of a working fluid supplied to the driveline disconnect clutch is adjusted in response to a rate of change in accelerator pedal position. Further, pressure of the working fluid may be decreased responsive to selected operating conditions.

Abstract: Methods and systems are provided for improving engine restart operations occurring during a transmission shift in a hybrid vehicle. Engine speed is controller during cranking and run-up to approach a transmission input shaft speed that is based on the future gear of the transmission shift. Engine speed is controlled via adjustments to spark, throttle, and/or fuel, to expedite engine speed reaching the synchronous speed.

Abstract: A method of controlling a vehicle, in which the vehicle includes an engine, a traction motor, and a clutch configured to selectively couple the engine to the motor, includes commanding the traction motor to provide an incremental torque. The motor is commanded to provide the incremental torque in response to the clutch being in a slipping condition. The magnitude of the commanded incremental torque is in response to the lesser of first and second torques. The first torque corresponds to an engine torque, and the second torque corresponds to a clutch torque capacity.

Abstract: Systems and methods for operating a transmission of a hybrid powertrain that includes a motor/generator are described. The systems and methods may classify transmission degradation in response to an estimated transmission input shaft speed that is determined from transmission output shaft speed. In one example, transmission degradation may be correctable transmission degradation, partial transmission degradation, and continuous transmission degradation.

Abstract: A parallel hybrid electric vehicle discrete step-ratio automatic transmission shift strategy attempts to cause a speed of a motor to approach a target motor speed to increase fuel economy for a coupled engine when in hybrid 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.
