摘要：A control apparatus for an automatic transmission, which executes a neutralcontrol by which an input clutch that transmits driving force from a driving source to the

automatic transmission is released when conditions, being i) a shift lever is in a positioncorresponding to a forward speed range, ii) an accelerator operation is not being

performed, iii) a brake operation is being performed, and iv) a vehicle speed is equal to, orless than, a predetermined vehicle speed, are fulfilled, is provided a controller whichdetects a road gradient and outputs a command to release the input clutch when i) thedetected road gradient is equal to, or less than, a predetermined value, and ii) theconditions are fulfilled. After the command has been output, the controller compares thedetected road gradient and the predetermined value and cancels the output of thecommand if the road gradient is greater than the predetermined value. Accordingly, fuelefficiency is able to be further improved during the neutral control.
