Abstract
A collision discriminating apparatus for vehicles having a collision detection device mounted on a part of the vehicle to detect the deformed amount of a collided portion deformed by collision of a collision object against the vehicle, and a collision object presuming device for presuming what object collided against the vehicle on the basis of the deformed amount of the collided portion detected, and the vehicle speed when the vehicle collided.
Claims22
A collision discriminating apparatus for vehicles comprising:
- a collision detection means mounted on a part of a vehicle for detecting a deformed amount of a collided portion deformed by collision of a collision object against said vehicle;
- and
- a collision object presuming means for presuming said collision object collided against the vehicle on the basis of the deformed amount of said collided portion detected, and a vehicle speed before or when the vehicle collided,
- wherein said, collision object presuming means comprises
- a means for detecting a first output of said collision detection means when a detected signal reaches a threshold level, for detecting a second output of said collision detection means when a first predetermined time has passed after the time when said first output is detected and for comparing a difference of the first and second outputs with reference levels.
A collision discriminating apparatus for vehicles comprising:
- a collision detection device mounted on a part of a vehicle and configured to detect a deformed amount of a collided portion deformed by collision of a collision object against said vehicle;
- and
- a collision object judging device configured to judge what type of collision object collided against the vehicle based on the deformed amount of said collided portion detected, and a vehicle speed before or when the vehicle collided with the object,
- wherein said collision object judging device includes a detector configured to detect a first output of said collision detection device when a detected signal reaches a threshold level, to detect a second output of said collision detection device when a first predetermined time has passed after the time when said first output is detected and to compare a difference of the first and second outputs with reference levels.
