PURPOSE:To prevent aggravation of speed change feeling by correcting working liquid pressure supplied to the friction element of an automatic transmission, when the swirl control valve of an engine is worked. CONSTITUTION:When actuation of a swirl control valve (a) is detected by swirl control detecting means (e), transmission liquid pressure of a friction element (c) is corrected by a correcting means (f). Hereby, even when swirl control of an engine (b) and speed change of an automatic transmission (d) are synchronously performed, coupling of the friction element (c) is appropriately performed and variation of coupling timing is prevented. |
