<p>PURPOSE: A method for controlling the speed change in the up-shift of an automatic transmission for a vehicle is provided to suppress the generation of the blow-up by the mutual control with an engine and to improve the speed change feeling and durability by reducing the blow-up learning value. CONSTITUTION: An up-shift speed change command is outputted(S100). The blow-up is compared to 30rpm(S110). If the blow-up is over 30rpm, learning control in proportion to the blow degree is performed(S120). Otherwise, the sequence time from the time point(SS) when the speed change control command is outputted to the time point(SB) when physical speed change is realized is decided(S130). If the sequence time is shorter than a reference value, learning for tie-up is performed(S140). Otherwise, a normal control is performed(S150).</p> |
