The contact position is set as a reference point of the displacement. The value of the pressure activing on the piston is measured at a point of time when a detected displacement has reached a determined displacement which is set at a position specified distance away from the reference point to the other side.

摘要： PROBLEM TO BE SOLVED: To suppress uncomfortable feeling caused by step-by-step change in deceleration before and after downshift during inertia running, in an automatic transmission in which a plurality of gear stages are achieved. SOLUTION: When a downshift start prediction means 112 determines before predetermined time T1 that downshift is actually started during inertia running, engagement pressure P IN is gradually increased, such that transmitting torque is gradually generated with respect to a third engagement element by a shift control means 110 until the downshift is started. When the downshift is started, the engagement pressure P IN is declined such that the third engagement element is released within predetermined time T 2 , and internal tie-up of the automatic transmission 10 is gradually generated by the third engagement element. Therefore, the internal tie-up gradually increases deceleration G from the predetermined time T 1 before the start of downshift. As a result, step-by-step increase in the deceleration G accompanied by the downshift is suppressed, and uncomfortable feeling caused by the step-by-step change in the deceleration G before and after the downshift is suppressed.
