Abstract

PURPOSE:To promote the improvement of stability of control and its convergency and the orientation of arithmetic processing to its high speed by using the present and past deviations of the actual slip amount from the target slip amount for the calculation of a feedback amount to a slip control unit. CONSTITUTION:Detecting a slip amount of a torque converter in a detecting means (c) and calculating the deviation from a target slip amount in a deviation arithmetic means (d) further multiplying the present and past deviation by a control parameter, a feedback amount is calculated in an arithmetic means (e). And actuating a slip control means (f) in accordance with the calculated feedback amount in a feedback control means (g), for instance, when the actual slip amount exceeds the target slip amount, a lockup clutch (b) is controlled in the tightening direction. Thus improving the stability of control and its convergency, while because the deviation, calculated in each arithmetic period, is used for calculation thereafter, arithmetic processing can be performed in a high speed.
