<p>PROBLEM TO BE SOLVED: To provide a slip control device for lockup clutch for vehicles which is capable of more accurately judging whether switching over to speed reducing slip control is favorably performed or not, and of performing switching over to the speed reducing slip control. SOLUTION: When an actual slip amount NSLP is judged to be larger than a transient state judging reference value KGSLE by a transient state slip amount judging means 200, speed reducing slip control is terminated by a speed reducing slip terminating means 202, and thus it becomes possible to make a relatively strict judgement, which is required in the transient state. Further, since a slip control pressure PSLU is corrected to a higher value by a control pressure learning correcting means 204 when the speed reducing slip control is terminated, the actual slip amount NSLP is not increased to the negative side in the following speed reducing slip control, and thus switching over to the speed reducing slip control is favorably performed.</p> |
