Abstract

PURPOSE: To save the fuel cost and reduce a shock and fluctuation of the speed of a vehicle when the speed is changed by increasing the efficiency of power of a torque converter through the application of the lock-up control to two or more speed- change stages.
CONSTITUTION: The speed-change gearing is conducted by determining a speed stage to be changed based on the 1st index of the rotational speed of the output axis of a torque converter or the rotational speed corresponding thereto, the 2nd index of the opening degree of an engine throttle valve or the quantity showing the operational condition of an engine or the like, and the 3rd index of the shift lever position and the speed-change stage, etc. And, when the 1st and 2nd indexes are in a predetermined area of lock-up operation in each of two or more speed-change stages, the torque converter is locked up, while the lock-up is released when the indexes are out of the area. Under such a controlling method, the lock-up is made released when the speed change is conducted.
