To provide a power supply system capable of protecting an information processing device even if the information processing device is inappropriately removed.SOLUTION: A power supply system 2 includes an MPU 20 attachable to and detachable from a vehicle 1. A power supply control part 13 includes an auxiliary power supply control part 27 for performing power interruption accompanied with data storage to the MPU 20 by executing an emergency shutdown on the basis of an emergency SD signal to be inputted in both a travel possible state and a travel impossible state of the vehicle 1. The power supply system includes an electrical connection monitoring part 22a for outputting the emergency SD signal in the case of monitoring an electrical connection state of the MPU 20 and detecting abnormality, and an attachment and detachment operation detection part 22b for outputting the emergency SD signal to the auxiliary power supply control part 27 in the case of detecting a removal operation of the MPU 20.SELECTED DRAWING: Figure 2

    【課題】情報処理装置が不適切に取り外されても、情報処理装置を保護できる電源システムを提供する。【解決手段】車両1への着脱が可能なMPU20を備える電源システム2である。電力供給制御部13は、車両1が走行可能および走行不能な状態の双方において、入力される緊急SD信号に基づき緊急シャットダウンを実行することにより、MPU20に対してデータの保存を伴った電力遮断を行う補助電力供給制御部27を含む。MPU20の電気的接続状態を監視して異常を検出した場合に、緊急SD信号を出力する電気的接続監視部22aと、MPU20の取り外し操作を検出した場合に、補助電力供給制御部27に緊急SD信号を出力する着脱操作検知部22bと、を有する。【選択図】図2
