| 20110154931 | METHOD FOR IMPROVING SHIFT QUALITY IN AN AUTOMATIC TRANSMISSION - A method is provided for improving shift quality in an automatic transmission. In many automatic transmissions, the shift quality during lift foot upshifts is unsatisfying.

In order to provide an automatic transmission which overcomes these two problems, a first and a second positive torque requests are initiated on upshift coasts. This measure improves the global shift feel by controlling the engine toque level at shift order and at synchronization: the engine torque level at the beginning of the gear shift is smoothly decreased to reduce the initial bump and is controlled at the synchronization to reduce the amplitude of underlap when the clutch capacity is rising. | 06-30-2011 |
