    摘要： In a vehicle bumper structure, an optical fiber sensor (32) is provided in a vehicle width direction on the front surface of a front-bumper reinforcement (30). A front-bumper absorber (28) is provided in front of the optical fiber sensor (32), the front-bumper absorber (28) formed of a soft absorber (54) and a hard absorber (56). The hard absorber is disposed at the bumper center region where the thickness of the bumper is increased. Accordingly, the thickness of the soft absorber (54) becomes substantially uniform in the vehicle width direction, so that a substantially uniform load is inputted to the optical fiber sensor (32) regardless of the collision position of the bumper with an object. As a result, variations in the output of the load-sensing unit are reduced.

    摘要： An optical fiber sensor can be interposed between a bumper reinforcement and a load transmitting plate to extend in the direction of width of a vehicle along with the bumper reinforcement. In this case, when a change does not occur substantially in an immediately previous predetermined period in an output voltage of a light emission amount of the optical fiber sensor, a feedback control is performed in such a way that the change becomes a level of zero of the output voltage of the optical fiber sensor. In contrast, when a change in the output voltage is not substantially zero, the immediately previous state of emission of light is maintained. Accordingly, it is possible to effectively compensate a zero point shift caused by a temperature change or/and an aging degradation of the optical fiber sensor.

    摘要： An optical fiber 1 includes a core 11 and a cladding material 12. In a collision detection optical fiber sensor 100, a plurality of linear members 2 and 3 are twisted around an outer periphery of the cladding material 12 of the optical fiber 1. An elastic member 6 of the liner member 2 has an elasticity different from that of an elastic member 7 of the first linear member 3. The hardness of the elastic member 6 is lower than that of the elastic member 7. A rubber hardness difference measured by a durometer type A according to a JIS K6253 between the elastic member 6 and the elastic member 7 is not less than 10.
