摘要： Methods and systems are provided for reducing driveline unwinding during successive engine shutdown and restart operations. In one example, during an engine shutdown, torsion is maintained in a transmission gear-train until an engine restart is requested by engaging one or more transmission clutches while applying wheel brakes.

摘要： Methods and systems are provided for controlling a vehicle engine coupled to a stepped-gear-ratio transmission. One example method comprises, in response to a first vehicle moving condition, shutting down the engine and at least partially disengaging the transmission while the vehicle is moving; and during a subsequent restart, while the vehicle is moving, starting the engine using starter motor assistance and adjusting a degree of engagement of a transmission clutch to adjust a torque transmitted to a wheel of the vehicle.

摘要： Systems and methods are provided for controlling a vehicle system including an engine that is selectively shut-down during engine idle-stop conditions, the system further including a hydraulic circuit comprising a hydraulically actuated transmission component, an accumulator, and an auxiliary transmission fluid pump. One example method comprises, during a first idle-stop engine shut-down condition, where the accumulator pressure is above a threshold, delivering pressurized transmission fluid to the hydraulic circuit from the accumulator, while disabling the auxiliary pump. The method further comprises, during a second idle-stop engine shut-down condition, where the accumulator pressure is below the threshold, operating the auxiliary pump and delivering at least some pressurized transmission fluid to the hydraulic circuit from the operating pump without travelling through the accumulator.

摘要： Methods and systems are provided for pressurizing a transmission hydraulic circuit including a transmission mechanical pump coupled to an engine though a gearbox. One example method comprises, during an engine start, adjusting a speed ratio between the transmission pump and the engine between a first speed ratio and a second speed ratio, the pump rotating faster relative to the engine at the first speed ratio as compared with the second speed ratio. In this way, the pump may be driven at different speed ratios relative to the engine to provide better pressurization in the transmission.
