PURPOSE:To prevent a speed change shock by outputting a shift down signal with delay after outputting a lock up release signal if engine load is in upward tendency when a shift down 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 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 down signal Cp' is output from speed change control means E in the lock up state, according to an output of load condition detection means G, if engine load is upward tendency, a lock up release signal Cq' is output in synchronization with the signal Cp', and if engine load is downward tendency, the signal Cp' is output with delay after outputting the signal Cq' by outputting adjust means F. |
