PURPOSE: To converge a slip rate at a target value within a specified converging time and prevent hunging of the slip rate after starting controlling in a device which controls a slip rate between an input shaft and an output shaft of a torque converter through engagement force of a direct connection clutch. CONSTITUTION: In execution of slip controlling, a reference control rate DTY is computed for controlling a slip rate NSLP to be a target slip rate TSLP by means of a reference control rate computation part 70. In addition, a converging time CSPIN is counted by means of a learning correction rate computation part 80, which time is required until the slip rate NSLP reaches a threshold value NSLPS set based on the target slip rate TSLP after starting controlling. A learning correction rate DL is renewed in respect to the reference control rate DTY based on the counted converging time CSPIN and a target converging time KSPIN. From the next controlling, the reference control rate DTY is corrected through the learning correction rate DL which is renewed. Engagement force of a lock-up clutch is adjusted through a correction control rate DTYR after correction. |
