Control device and control method for a vehicular automatic transmission |
摘要 |
When a clutch is disengaged in a D-N shift, a duty ratio of a linear solenoid in a stand-by state at a constant pressure is calculated according to the following equation by using the following values: a reference duty ratio in a stand-by state at a constant pressure; a correction value for an AT oil temperature; a correction value for an engine speed; and respective learning correction values in a N-D shift and a 4-3 coast down shift in which the clutch is engaged. In the equation, K is a coefficient and has a constant value predetermined in the range of 0<=K&LE;1. |
