Pressure sensor malfunction detection device
An external impact avoiding part makes a sensor failure detection part withhold from determining that a right or left door pressure sensor has failed when a right-left detection difference calculated at first time is a threshold value or larger, and makes a detection value comparison part calculate the right-left detection difference again after a calming time has elapsed. An effect of closing operation of a right door on the right door pressure sensor or an effect of closing operation of a left door on the left door pressure sensor reduces during the calming time. The avoiding part subsequently makes the detection part compare the right-left detection difference calculated again with the threshold value. As a result of the comparison, when the right-left detection difference is the threshold value or larger, the avoiding part makes the detection part determine that the right or left door pressure sensor has failed.
