Patent ID: 8886420

Claim:
A control method for an automatic transmission capable of performing switching between an automatic shift mode in which shifting is automatically performed according to a travel state of a vehicle, and a manual shift mode in which shifting is performed by a shift operation of a driver, the control method comprising: an automatic shift step of executing automatic shift control by which shifting is automatically performed, regardless of the shift operation of the driver, when a predetermined condition is fulfilled in a state in which the manual shift mode is executed; a cancellation step of canceling the shift performed by a shift operation for performing shifting in the same direction as that of the shifting performed by the automatic shift control, when the shift operation is performed before an input revolution speed correlation value that varies as the shifting of the automatic transmission advances becomes a predetermined value, which has been set in advance as a value at the time the driver recognizes the shifting, after the automatic shift control has been started; a first display switching step of switching a shift stage display at a timing at which the shift operation that is to be canceled in the cancellation step has been performed, following the execution of the cancellation step; and a second display switching step of switching the shift stage display at a timing at which the input revolution speed correlation value becomes the predetermined value when a shift operation is not performed within a period of time from when the automatic shift control is started till when the input revolution speed correlation value becomes the predetermined value.
