Abstract:
1. A control device for an automatic transmission that is operated in an automatic mode in which a gear range of the automatic transmission is automatically controlled and a manual mode in which the gear range is changeable one by one upon operation of either one of a shift-up switch and a shift-down switch, comprising: a switch-operation-signal output circuit that outputs different output voltages at least when only the shift-up switch is turned on and when only the shift-down switch is turned on; and an operation determination unit which determines a mode change between the automatic mode and the manual mode based on the output voltage by the switch-operation-signal output circuit and which determines a change of the gear range in the manual mode, wherein the switch-operation-signal output circuit: the operation determination unit maintains the automatic mode until both shift-up switch and shift-down switch are operated within a predetermined first threshold time, and switches to the manual mode from the automatic mode when the fourth output voltage is output within the predetermined first threshold time or the second output voltage and the third output voltage are both output within the predetermined first threshold time.
