ABSTRACT:
A device for controlling an automatic transmission and an engine for vehicles expanding a range of direct drive to improve fuel efficiency and decreasing the shock due to the transmission of torque at the time of acceleration or deceleration. The device comprises a torque converter 3 for transmitting the output torque of an engine 1, a direct drive mechanism 4 for directly coupling an output shaft 3a of the torque converter to an output shaft 1a of said engine, a control 6A for controlling an automatic transmission 2 that includes the torque converter and the direct drive mechanism, a sensor 8 for detecting the opening degree A of an accelerator 7, a throttle valve 9 for adjusting the amount of the air intaken by the engine, an actuator 10 for opening or closing the throttle valve, and a throttle valve control for controlling the throttle valve opening degree T, wherein the automatic transmission control resets the directly coupled state when the accelerator pedal opening degree has changed by more than a predetermined amount that corresponds to a transient operation condition, and the throttle valve control delays the operation for opening the throttle valve following the accelerator pedal opening degree when the accelerator pedal opening degree has changed by more than the predetermined amount.
