摘要： A hybrid electric vehicle includes an engine that can selectively provide drive torque to propel the vehicle. An electric machine also selectively provides drive torque. A differential transfers the torque to and amongst wheels. A planetary gearset is coupled to the engine and has a ring-gear for transmitting ring-gear-torque to the differential. A continuous torque transfer member operatively couples the ring-gear and the electric machine to the differential. At least one controller is configured to alter engine output based on a ring-gear-torque-threshold. This enables a desired torque to transfer through the continuous torque transfer member to the differential.

摘要： A hybrid electric vehicle includes an engine and an electric motor both configured to generate a vehicle powertrain torque and a controller programmed to control the powertrain torque for a limited duration in anticipation of a powertrain torque variation scenario using a damping function, wherein the damping function adjusts the vehicle powertrain torque based on a difference between a measured motor speed and a desired motor speed using the electric motor to counteract a powertrain speed oscillation.

摘要： Two methods may be used to start the engine of a hybrid electric vehicle while the vehicle is moving under electric power. When smoothness is most important, a disconnect clutch is partially engaged to initiate engine rotation and then released as the engine accelerates under its own power toward a motor speed. When rapid starting is most important, the disconnect clutch torque capacity is controlled to decrease the time required for the engine to accelerates to the motor speed. A torque converter bypass clutch is disengaged during the engine restart under either method. Also, the motor torque is adjusted under either method to compensate for the torque provided to the engine.

摘要： A system and method for controlling a fraction motor in a hybrid vehicle includes varying a traction motor torque in response to an engine cylinder misfire. The traction motor torque is varied to compensate for an engine torque shortfall due to the engine cylinder misfire, reducing a torque imbalance caused by the misfire.

摘要： A hybrid electric vehicle includes an engine and an electric machine, both capable of providing torque to transmission gearing. A clutch is disposed between the engine and the electric machine and is configured to selectively couple the engine to the electric machine. At times in which control of the amount of engine torque transmitted to the gearing is desirable, a controller is programmed to slip the clutch. If the controller is able to determine the amount of torque transmitted through the slipping clutch, the controller alters an output of the electric machine based upon the torque through the clutch. If, however, the controller is unable to determine the amount of torque transmitted through the slipping clutch, the controller alters the output of the electric machine based upon an acceleration of the electric machine.
