Occupant protection system

摘要

An occupant protection system is provided. The occupant protection system includes a sensor for detecting an impact at a time of collision, a determination device for determining the collision based on a detection signal of the sensor, and a an occupant state detection device for detecting whether an occupant's posture is maintainable. When the occupant's posture is maintainable after a primary-collision, the determination device determines a secondary-collision by comparing the detection signal of the sensor with a first threshold. When the occupant's posture is not maintainable after the primary collision, the determination device determines the secondary-collision by comparing the detection signal of the sensor with a second threshold smaller than the first threshold.

1. An occupant protection system comprising:
a sensor for detecting an impact at a time of collision of a vehicle, wherein the collision of the vehicle includes a primary-collision and a secondary-collision occurring due to movement of the vehicle resulting from the primary-collision; a determination device for determining the primary-collision by comparing a detection signal of the sensor with a primary-collision determination threshold; and an occupant state detection device for detecting whether a posture of an occupant of the vehicle is maintainable; wherein: for the secondary-collision occurring due to the movement of the vehicle resulting from the primary-collision, the determination device determines the secondary-collision; when the occupant state detection device detects that the posture of the occupant is maintainable after the determination device determines that the primary-collision has occurred, the determination device determines the secondary-collision by comparing the detection signal of the sensor with a first secondary-collision determination threshold; and when the occupant state detection device detects that the posture of the occupant is not maintainable after the determination device determines that the primary-collision has occurred, the determination device determines the secondary-collision by comparing the detection signal of the sensor with a second secondary-collision determination threshold smaller than the first secondary-collision determination threshold.
