摘要： A vehicle includes a first axle having a first electric machine, a second axle having a second electric machine and a controller. The controller is programmed to, in a user-selected four-wheel drive mode, command a first torque to the first electric machine based on a driver-demanded torque and a speed of the second axle, and command a second torque to the second electric machine based on a comparison of the driver-demanded torque and the first torque and further based on a speed of the first axle.

摘要： Methods and systems are provided for adjusting clutch pressures and electric machine torques as a function of a stability metric threshold(s) in order to balance performance and charging of an onboard energy storage device. In one example, a method includes during an upshift of a transmission from a first gear to a second gear, adjusting a clutch pressure of the transmission to adjust slippage of a clutch in response to a vehicle stability control parameter exceeding a threshold. In this way, torque delivered to a transmission output shaft may be reduced, which may increase vehicle stability.

摘要： A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated fiction torque elements to effect gear ratio upshifts. The friction torque elements are synchronously engaged and released during a torque phase of an upshift event as torque from a torque source is increased while allowing the off-going friction elements to slip, followed by an inertia phase during which torque from a torque source is modulated. A perceptible transmission output torque reduction during an upshift is avoided. Measured torque values are used during a torque phase of the upshift to correct an estimated oncoming friction element target torque so that transient torque disturbances at an oncoming clutch are avoided and torque transients at the output shaft are reduced.

摘要： Methods and systems are provided for operating a vehicle driveline where the vehicle driveline does not include a torque converter. In one example, a method comprises controlling a capacity of a clutch configured to transmit torque between an engine and a transmission, and an output of an electric motor positioned in a driveline of the hybrid vehicle during a vehicle launch to emulate a performance of a torque converter positioned in the driveline of the vehicle. In this way, vehicle launch maneuvers may be conducted for vehicles that are equipped with a clutch and an electric motor, such that said launch maneuvers mimic those of a vehicle with a torque converter, which may improve customer satisfaction and improve engine efficiency.

摘要： Systems and methods for operating a vehicle that includes a manual transmission are presented. In one example, a clutch actuator that responds to a position of a manual operated clutch pedal is adjusted to operate a clutch so that the vehicle may be stopped, while the engine is running or not, without the driver applying the clutch pedal.

摘要： Systems and methods for improving transmission gear shifting of a hybrid vehicle are presented. The systems and methods may allow transmission input shaft torque to be lowered to levels where driveline torque disturbances may be reduced even though the driveline has a larger inertia. In one example, driveline torque may be reduced via retarding spark timing.

摘要： Methods and systems are provided for operating a driveline of a hybrid vehicle that includes an internal combustion engine, an electric machine, and a transmission are described. In one example, the engine is started and coupled to the driveline via closing a clutch of a dual clutch transmission. Speed of the engine and clutch pressure are controlled to reduce driveline torque disturbances and provide a desired wheel torque.

摘要： Methods and systems are provided for adapting a pressure to torque transfer function of a clutch of a dual clutch transmission. In one example, a method includes operating a first clutch of the dual clutch transmission at a selected capacity to change a speed of a first transmission input shaft to a desired speed, adjusting values of a torque transfer function of the first clutch based on a rate of the speed change, and maintaining driver demanded wheel torque during the adjusting via controlling torque output of an electric motor positioned in the driveline. In this way, the method may be used to adapt both positive and negative torque transfer functions.
