摘要： Methods and systems are provided for controlling a vehicle system including an engine that is selectively shut-down during engine idle-stop conditions, the vehicle system further including a hydraulically actuated transmission component. One example method comprises, during an idle-stop engine shut-down, adjusting a hydraulic actuation of the transmission component to adjust drag torque on the engine to stop the engine.

摘要： Systems and methods are provided for restarting an engine that can be selectively deactivated during idle-stop conditions. In one embodiment, current is directed to a starter motor and an electric brake sequentially by limiting the current supplied to one while current is supplied to the other, an order of delivering the current based on a timing of a restart request relative to an electric brake request, as well as vehicle operating conditions at the time the requests were received. By coordinating the operation of a starter motor with the operation of an electric brake, loading of the engine system's electrical supply can be reduced.

摘要： A hybrid vehicle has a battery, a regenerative braking system, a transmission, and a controller. The controller boosts and strokes a hydraulic cylinder of an on-coming clutch when the state-of-charge of the battery allows regenerative braking and in response to a pedal actuation. The controller boosts and strokes the hydraulic cylinder before a disconnect clutch is opened and the transmission is downshifted to increase regenerative braking efficiency.

摘要： A vehicle includes an engine, a traction motor, and a torque converter that is driven by the traction motor. A clutch arrangement mechanically couples an output of the torque converter to transmission gearing. A controller is provided in the vehicle that is configured to command an increase in slip, or decrease in clutch pressure, in the clutch arrangement in response to an increase in speed of the traction motor. The commanding of an increase in slip enables a product of the torque ratio of the torque converter and an input torque to the torque converter to remain generally constant during the increase in speed of the traction motor.

摘要： A vehicle includes an engine and a traction motor. A clutch is configured to selectively mechanically couple the engine to the traction motor. A controller or controllers are provided that are configured to command a change in magnitude of an electric current supplied to the electric machine. The command is made in response to initiation of the clutch engaging the traction motor to the engine. The change in magnitude of the electric current ensures the speed of the traction motor remains generally constant during clutch engagement while a speed of the engine is less than that of the traction motor.
