Abstract:
A control device of an automatic transmission of a motor vehicle, including lock-up control means for controlling a coupling state between input and output elements of a torque converter clutch that transmits a driving force from an engine to the automatic transmission, said control device comprising:a throttle control device that controls an opening degree of a throttle valve;accelerator position detecting means for detecting an accelerator pedal position;a cruise control device that controls the opening degree of the throttle valve to maintain a vehicle speed at a predetermined vehicle speed; andtarget throttle opening setting means for calculating a pseudo accelerator pedal position, and setting a target throttle opening based on the pseudo accelerator pedal position,wherein said lock-up control means controls the coupling state between the input and output elements of the torque converter clutch based on said calculated pseudo accelerator pedal position when the cruise control device is in operation, and controls the coupling state based on the detected accelerator pedal position detected by said accelerator position detecting means when the cruise control device is not in operation.
