Abstract

A collision detection system includes a shock detecting device, a collision position detecting device, a correcting device, and a collision determining device. The shock detecting device detects a magnitude of a shock due to a collision. The collision position detecting device detects a collision position of the collision. The correcting device corrects a detection result detected by the shock detecting device based on a detection result detected by the collision position detecting device. The collision determining device determines the collision based on a corrected result corrected by the correcting device.

Claims

1. A collision detection system comprising:

a shock detecting device that detects a magnitude of a shock due to a collision;

a collision position detecting device that detects a collision position of the collision;

a correcting device that corrects a detection result detected by the shock detecting device based on a detection result detected by the collision position detecting device; and

a collision determining device that determines the collision based on a corrected result corrected by the correcting device.

2. The collision detection system according to claim 1, wherein:

the collision position detecting device includes a plurality of contacts, each of which is turned on by the shock of the collision.

3. The collision detection system according to claim 2, wherein:

at least one of the plurality of contacts has a first detection region, which overlaps with a second detection region of anther one of the plurality of contacts;

the at least one of the plurality of contacts is turned on when the shock of the collision is applied to the first detection region; and

the anther one of the plurality of contacts is turned on when the shock of the collision is applied to the second detection region.

4. The collision detection system according to claim 1, wherein:

the shock detecting device includes at least one of an optical fiber, a strain gauge, a pressure sensor, and an acceleration sensor.

5. The collision detection system according to claim 1, the collision detection system further comprising:

a vehicle, on which the collision detection system is mounted, wherein the collision detection system detects the collision to the vehicle.

6. The collision detection system according to claim 1, further comprising:

a bumper of a vehicle, wherein the shock detecting device is coupled to the bumper of the vehicle.

7. The collision detection system according to claim 2, wherein:

each of the plurality of contacts is turned on to detect a corresponding collision position when the shock of the collision is applied to the corresponding collision position.

8. A protection system comprising:

the collision detection system according to claim 1;

and

a protecting device that protects one of a passenger of a vehicle and a pedestrian based on the detection result of the collision position detecting device and a determining result of the collision determining device.
