Abstract: 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.

Abstract: A pressure sensor, which detects a pressure in a space close to an inner side of an exterior member of a vehicle, and an occupant protecting device, which protects an occupant inside a vehicle are provided. An electronic control unit determines an occurrence of collision in the case where the pressure and a change per unit time of the pressure each satisfy a collision condition, and then makes the occupant protecting device operate. At this time, the collision condition is set to restrict the determination indicative of an occurrence of collision unless the change per unit time of the pressure is larger with lowering the pressure.

Abstract: An object is to be able to accurately discriminate an object of a collision. A device has a collision detection to which are connected a pressure sensor that detects pressure within a pressure chamber, and a vehicle speed sensor that detects vehicle speed, and the collision detection determines effective mass of a collided object on the basis of an integrated value obtained by integrating, at a predetermined sectional integration width, detection results of the pressure sensor, and a converted vehicle speed signal obtained by subtracting a predetermined value ? from a vehicle speed signal of the vehicle speed sensor by using a predetermined vehicle speed converting map or the like. Then, when the determined effective mass exceeds a predetermined threshold value, the collided object is discriminated as a pedestrian.
