PURPOSE:To reduce a speed change shock by outputting a lock up release signal in synchronization with the generation of a shift up signal or delaying the outputting of a lock up release signal according to the rotational frequency change condition of an engine output shaft when a shift up signal is generated in the lock up state. CONSTITUTION:The above control device is adapted to intermittently operate a lock up mechanism A provided on a torque converter by controlling lock up electromagnetic means 13, and operate a geared speed change mechanism C to change speed by controlling a speed change electromagnetic means D. In this case, in the condition where a lock up signal is output from lock up control means E, when a shift up signal CP is output from speed change control means F, according to an output of rotational frequency change condition detection means H, if the rotational frequency of an engine output shaft is downward tendency, a lock up release signal Cq' is output in synchronization with outputting of the signal CP and if it is upward tendency, the outputting of the signal Cq' is delayed by lock up release timing adjust means G. |
