Damping oscillations during a gear ratio change of a dual clutch powershift transmission |
摘要 |
A method for controlling an upshift in a vehicle transmission includes transferring engine torque from an offgoing clutch to an oncoming clutch, using a torque capacity of the offgoing clutch to dampen oscillations when a difference between a speed of a transmission offgoing input and a calculated expected speed of said input is greater than a reference speed difference, and modulating engine torque during a ratio change phase of the shift. |
