PURPOSE:To prevent a speed change shock by outputting a lock up release signal in synchronization with generation of a shift up signal or delaying the outputting of the lock up release signal according to results of comparison between a detection value and a designated value of engine load when a shift up signal is generated in the lock up state. CONSTITUTION:The above control device is adapted to intermittently control a lock up mechanism A provided on a torque converter by controlling lock up electromagnetic means B and operate a geared speed change mechanism C to change speed by controlling speed change electromagnetic means D. In this case, when a shift up signal CP is output from speed change control means E in the lock up state, according to an output of engine load detection means G, if engine load is smaller than a designated value, a lock up release signal Cq' is output in synchronization with outputting of the signal CP, and if it is larger than the designated value, outputting of the lock up release signal Cq' is delayed by lock up release timing adjust means F. |
