摘要

The ECU power-on (that is, in S100, "Yes") to perform the down-shift output of the shift command and when the judgment is turned off; Power-on downshift control to perform the hydraulic pressure supplied to the friction engagement element, and; When less than or equal to the difference ΔTT threshold value (1) between the target input torque and the estimated input torque (that is, in step S130, "Yes"), the power-allow the hydraulic pressure correction is supplied to the friction engagement element during the on downshift, and; Power to run the program for correcting the hydraulic pressure supplied to the friction engagement element during the on downshift. ; Hydraulic control unit, determining unit, oil pressure correction, the target input torque and the actual input torque, forward gear speed, the reverse gear speed, the accelerator depression amount
