PROBLEM TO BE SOLVED: To provide a shift-by-wire type automatic transmission system capable of switching a shift range of an automatic transmission even when an ignition switch is in an OFF state.SOLUTION: A shift-by-wire type automatic transmission system includes a controller 105 in which, by turning on an ignition switch 101, power from a power supply device 106 is supplied by a first power supply path 11 via the ignition switch 101. The shift-by-wire type automatic transmission system includes a second power supply path 12 for supplying power to the controller 105 from the power supply device 106 without going through the ignition switch 101. It also includes a power source switching part 110 for switching the power supply to the controller 105 from the power supply device 106 between the first power supply path 11 and the second power supply path 12, in a state where the ignition switch 101 is in an OFF state.SELECTED DRAWING: Figure 1 【課題】イグニッションスイッチがオフの状態であっても、自動変速機のシフトレンジを切り替えることができる、シフトバイワイヤ方式の自動変速機システムを提供することを目的とする。【解決手段】本発明に係るシフトバイワイヤ方式の自動変速機システムは、イグニッションスイッチ１０１をオンにすることにより、イグニッションスイッチ１０１を介した第１給電経路１１によって給電装置１０６から電力が供給される制御器１０５と、を備えたシフトバイワイヤ方式の自動変速機システムであって、イグニッションスイッチ１０１を介さずに給電装置１０６から制御器１０５に電力を供給する第２給電経路１２を備え、イグニッションスイッチ１０１がオフの状態で、給電装置１０６から制御器１０５への電力の供給を第１給電経路１１と第２給電経路１２との間で切り替える電源切替部１１０と、を備える。【選択図】図１
