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.

Collision sensing device and occupant protecting system

In a passenger protection device, an object detection unit detects a relative position of an object in a circumference of a vehicle to the vehicle. A side collision prediction unit predicts that the object is about to collide with a side face of the vehicle, based on the relative position detected by the object detection unit. An impact detection unit detects an impact of the object on the vehicle side face. A side collision judgment unit determines whether the object has collided with the vehicle side face, based on the impact detected by the impact detection unit. A passenger protection unit protects a passenger in the vehicle. When the side collision prediction unit predicts that the object is about to collide with the vehicle side face and the side collision judgment unit determines that the object has collided with the vehicle side face, the passenger protection unit is initiated.

A vehicle occupant protection apparatus includes a first collision detection mechanism provided for a vehicle and that detects a collision of the vehicle; a second collision detection mechanism provided closer to a middle of the vehicle than the first collision detection mechanism and that detects a collision of the vehicle; a first protection mechanism that protects an occupant from a collision of the vehicle; a controller that activates the first protection mechanism at the time when the first and second collision detection mechanisms detect a collision of the vehicle; and a collision prediction mechanism that predicts a collision of the vehicle. Every time the collision prediction mechanism predicts a collision of the vehicle in a direction from the first collision detection mechanism toward the middle of the vehicle, the controller activates the first protection mechanism at the time when the first collision detection mechanism detects the collision of the vehicle.

A target position is estimated in such a manner to maintain target position continuity, with high accuracy, even when the X coordinate displacement of the target is large. On a scan in which the target position is not detected, when a trajectory of the target in the past is within a predetermined region in the vicinity of the Y-axis, a position for estimate is a position having an X coordinate resulting from shifting, by a first displacement, the X coordinate estimated according to the trajectory, on a basis of the X coordinate of a previous position, while when the trajectory is not within the predetermined region, the position for estimate is a position having an X coordinate resulting from shifting, by a second displacement that is larger than the first displacement, the X coordinate estimated according to the trajectory, on a basis of the X coordinate of a previous position.
