To provide an abnormality detection device that accurately detects abnormality in a stop lamp system.SOLUTION: An abnormality detection device for a stop lamp system comprises: a stop lamp: a stroke sensor (an S sensor) that detects an amount of depression of a brake pedal; a stop lamp SW that is turned on when the S sensor value is equal to or higher than a predetermined value: a first wire that connects the stop lamp SW and a stop lamp and outputs a drive signal to the stop lamp upon turning on of the stop lamp SW; a main ECU that monitors the S sensor value and the presence or absence of the drive signal in a predetermined position in the first wire; one or more sub-ECUs that monitor the presence or absence of the drive signals in one or more positions located further on a stop lamp side than the predetermined position in the first wire; and a second wire that connects a main ECU and one or more sub-ECU and communicates with a plurality of ECUs about the presence or absence of the drive signal in each position in the first wire. The main ECU detects a system abnormality on the basis of the S sensor value and the presence or absence of a drive signal in each position in the first wire.SELECTED DRAWING: Figure 1

    【課題】ストップランプシステムの異常検出を精度よく行う異常検出装置を提供する。【解決手段】ストップランプと、ブレーキペダルの踏込量を検出するストロークセンサー(Sセンサー)と、Sセンサー値が所定値以上である場合にオンとなるストップランプSWと、ストップランプSWとストップランプとを接続し、ストップランプSWのオンで駆動信号をストップランプに出力する第1配線と、Sセンサー値及び第1配線における所定位置の駆動信号の有無を監視するメインECUと、第1配線の所定位置よりもストップランプ側となる1つ以上の位置の駆動信号の有無をそれぞれ監視する1つ以上のサブECUと、メインECUと1つ以上のサブECUとを接続し、複数のECU間で第1配線における各位置の駆動信号の有無を通信する第2配線とを備え、メインECUは、Sセンサー値及び第1配線における各位置の駆動信号の有無に基づいてシステム異常を検出する。【選択図】図1
