PROBLEM TO BE SOLVED: To detect a deviation abnormality of a negative pressure sensor, and to avoid a malfunction accompanied by the execution of an automatic stop of an internal combustion engine when the deviation abnormality of the negative pressure sensor occurs, related to a negative pressure sensor abnormality detection device and a control device of the internal combustion engine.SOLUTION: A negative pressure sensor abnormality detection device comprises: a negative pressure sensor which outputs a signal corresponding to negative pressure created by a negative pressure pump which is necessary for assisting a brake operation of a driver; negative pressure detection means which detects the negative pressure on the basis of the signal from the negative pressure sensor; rotation number detection means which detects a rotation number of the negative pressure pump; and abnormality determination means which determines that the negative pressure sensor is in an abnormal state when a change of the negative pressure which is detected by the negative pressure detection means accompanied by an increase of the rotation number which is detected by the rotation number detection means is deviated from a prescribed change in a situation that a change of the brake operation of the driver falls into a prescribed range.SELECTED DRAWING: Figure 3

    【課題】本発明は、負圧センサ異常検出装置及び内燃機関の制御装置に係り、負圧センサの偏差異常を検出すること、及び、負圧センサの偏差異常が生じているときに内燃機関の自動的な停止が実行されることに伴う不都合を回避することにある。【解決手段】負圧センサ異常検出装置は、運転者のブレーキ操作を補助するのに必要な負圧ポンプにより生成される負圧に応じた信号を出力する負圧センサと、負圧センサからの信号に基づいて上記負圧を検出する負圧検出手段と、負圧ポンプの回転回数を検出する回転回数検出手段と、運転者のブレーキ操作の変化が所定範囲内に収まる状況で、負圧検出手段により検出される上記負圧の、回転回数検出手段により検出される回転回数の増加に伴う変化が所定変化から外れる場合に、負圧センサが異常状態にあると判定する異常判定手段と、を備える。【選択図】図3
