SLIP CONTROL DEVICE FOR VEHICLE

摘要

PURPOSE:To prevent the occurrence of a big re-slip of a driving wheel caused by the engagement of a lock-up clutch by maintaining the lock-up clutch in an engagement release condition during a given period after slip control finish too. CONSTITUTION:The engagement/release of the lock-up clutch C of a torque convertor between an engine E and a driving wheel D is controlled by a lock-up clutch control means A based on a preset lock-up characteristic. Here when the slip of the driving wheel D is detected by a slip detection means S, given torque to the driving wheel D reduces by a slip control means B via a given torque adjustment means F when a slip value is a given value or more, and also the engagement of the lock-up clutch C is forcedly released via an engagement release means G. When the slip control finishes, the release condition of a lock-up clutch engagement by the engagement release means G is maintained for a given time from finish by a delay means H. Thus the occurrence of a big re-slip can be prevented.
