Patent ID: 8175778

Claim:
An automatic shift-control apparatus that controls a shift-state of an automatic transmission based on a shift-mode selected from a shift-mode group including an automatic shift-mode and a manual shift-mode, wherein, when selection is switched from the automatic shift-mode to the manual shift-mode, the apparatus changes a shift-stage or a shift-range to a lower speed side, the control apparatus comprising: a state holding section that holds a state data of a current shift-stage regardless of reduction of a power-supply voltage; a selection state detecting section for detecting a selection state of the shift-mode group; a detection return determining section for determining that the selection state has returned from a first state in which the selection state detecting section cannot detect the shift-mode selection state to a second state in which such detection is possible; and a return-time adjusting section, wherein, during a standby-period after the detection return determining section determines the return, the return-time adjusting section sets a shift-state of the automatic transmission to the shift-stage or a shift-range that is held by the state holding section, and sets a shift-control by the automatic shift-mode, and wherein, after the standby-period, the return-time adjusting section continues the automatic shift-mode unless selecting operation is executed on the shift-mode group.
