PROBLEM TO BE SOLVED: To accomplish a stable shift control by stabilizing the slip starting point regardless of the situation of an engaging element such as a clutch, for example deterioration with time, enhance the durability by suppressing the slip of the engaging element to a specified extent and shortening the control period of the current shift range, and establish changing-over to the next step control in smooth continuity. SOLUTION: At the first step as the initial period of the control in the current shift range, a feedback control is made so that the clutching, etc., in the current range becomes the first target slippage ECL02 (S10-S24). Then the operation proceeds to the second step as the subsequent period, and a feedback control is made so that the clutching, etc., in the current range becomes the second target slippage ECL02, and the oil pressure command signal (supply oil pressure decremental torque command value QTRQ) is corrected in accordance with the deviation of the actual slippage from the second target slippage (S26-S34), and the next time oil pressure command signal is determined on the basis of the corrected value (S36). |
