Abstract:
A duty jumping amount at an actual shift-begin point (SB point) during static shifting is calculated dependent on an automatic transmission fluid temperature and a turbine torque. Therefore, an adjustment of hydraulic pressure supplied to an on-coming clutch at the SB point is optimized, and thereby a shift feel of an automatic transmission may be improved.
