Notification device and notification system

Abstract

A notification device includes an image acquisition unit that acquires images, a steady-state determination unit that determines whether a non-temporary malfunction state occurs in the camera system, a memory processing unit that stores malfunction information in a storage area, a start-up determination unit that determines whether the non-temporary malfunction state exists during the period until the steady-state determination unit is able to determine the occurrence of the non-temporary malfunction state, and an alarm output process processing unit that outputs an alarm when each determination unit determines that the non-temporary malfunction state exists. The start-up determination unit includes a previous information acquisition unit that acquires the malfunction information stored in the storage area when the control unit of the vehicle was turned off from a previous power-on state, and a provisional determination unit that determines that the non-temporary malfunction state exists if the previous information obtained by the previous information acquisition unit indicates that the non-temporary malfunction state exists, and determines that the non-temporary malfunction state does not exist if the previous information obtained by the previous information acquisition unit indicates that the non-temporary malfunction state does not exist.
