Clutch pressure control for improved transmission engagements and shifts |
摘要 |
A method for reducing transmission clutch engagement pressure during conditions when clutch hydraulic fluid is relatively more viscous. A clutch engagement pressure control signal is shaped by a system that has an addition branch (42) for shaping the control signal as the control signal is rising, a subtraction branch (44) for shaping the control signal as the control signal is falling, and a summing junction (46) for algebraically summing the signal outputs of the addition and the subtraction branches. |
