摘要： Calibration of an engine disconnect clutch for a hybrid electric powertrain. The clutch is prestroked while an engine and machine are stopped. A machine torque is increased until the machine starts rotating. A pressure of the clutch is adjusted as a function of a torque produced by the machine when the machine started rotating.

摘要： Regenerative torque is limited for a hybrid electric powertrain of a vehicle. A transmission controller determined torque limit is validated by a vehicle controller. The vehicle controller validates the torque limit using, individually or in combination, an actual status of a torque converter clutch, a detected status of the torque converter clutch, or a speed of the vehicle.

摘要： A method of smoothing hybrid vehicle engine shutdown. A powered and rotating electric machine is used to slow deceleration of an unpowered and rotating engine by transferring torque through a clutch from the machine to the unpowered engine. Prior to the machine being powered, torque may be transferred through the clutch from the unpowered and rotating engine to the unpowered machine to accelerate passage of the engine through a resonance frequency.

摘要： A method for controlling a vehicle regenerative braking event includes maintaining a converter clutch closed while braking, while an engine connected to the impeller is running, opening the converter clutch when impeller speed reaches a reference speed difference relative to engine idle speed, and while the engine is off, opening the converter clutch when impeller speed reaches a speed required for a transmission pump, connected to an impeller, to produce line pressure at a desired magnitude.

摘要： Methods and systems are provided, including a method for an electric vehicle having at least two motors providing drive torque. In one example, the method comprises operating with speed damping control, including determining that a first motor has more power authority than requested and a second motor has a shortage of power authority, and in response, reallocating power authority from the first motor to the second motor to increase usage of authorized power for speed damping. In one example of the method, the first motor and the second motor are in electronic communication with a centralized integrated control system.
