Abstract:
(EN) Provided are a failure diagnostic device for negative pressure sensors, a failure diagnostic method for negative pressure sensors, and a brake device such that it is possible to suppress a reduction in the diagnostic frequency of abnormalities in negative pressure sensors. This failure diagnostic device for negative pressure sensors comprises: a variation amount observation unit for observing the amount of variation in the detection signal of a negative pressure sensor when a brake pedal is released; and an abnormality determination unit for determining the negative pressure sensor is abnormal if the variation amount is a predetermined variation amount or less.
(FR) Dispositif de diagnostic de défaillance pour capteurs de pression négative, procédé de diagnostic de défaillance pour capteurs de pression négative, et dispositif de frein de telle sorte qu'il est possible de supprimer une réduction de la fréquence de diagnostic d'anomalies dans des capteurs de pression négative. Ce dispositif de diagnostic de défaillance pour capteurs de pression négative comprend : une unité d'observation de quantité de variation pour observer la quantité de variation dans le signal de détection d'un capteur de pression négative lorsqu'une pédale de frein est relâchée ; et une unité de détermination d'anomalie pour déterminer que le capteur de pression négative est anormal si la quantité de variation est une quantité de variation prédéfinie ou moins.
(JA) 負圧センサの異常診断の頻度低下を抑制できる負圧センサの故障診断装置、負圧センサの故障診断方法およびブレーキ装置を提供する。 負圧センサの故障診断装置は、ブレーキペダルが踏み戻されたときの負圧センサの検出信号の変動量を観測する変動量観測部と、変動量が所定の変動量以下の場合に、負圧センサが異常であると判定する異常判定部と、を備える。
