摘要： A collision detection device is provided with a load detection member 2 for detecting a collision load in a collision, and a mold member 3 which is molded to be integral with the load detection member 2. The mold member 3 covers at least the surface of a collision side of the load detection member 2, to absorb at least a part of impact energy in the collision by a resilient deformation of the mold member 3. Thus, the collision detection device is substantially resistant to an impact in the collision, while being simply manufactured.

摘要： A load detecting sensor includes a first member, a second member, and an optical fiber. The first member has a groove having a bottom portion and a column portion which defines the groove. The second member covers the groove of the first member so that a surrounded space is formed. The optical fiber is arranged in the surrounded space. At least one of the first member and the second member is made of an elastic body. The surrounded space is deformable when load is applied to at least one of the first and the second members. When load is applied to at least one of the first and the second members, the deformation of the optical fiber is caused following the deformation of the surrounded space. Hereby, the load detecting sensor, which can decrease the manufacturing cost and increase the detecting sensitivity by the optical fiber, can be obtained.

摘要： An activation control apparatus controls activation of an airbag unit. An electronic control unit detects a floor deceleration Gf and front decelerations GI, Gr from signals output from a floor sensor and front sensors. Also, the electronic control unit calculates a velocity change Vn from the floor deceleration Gf, and determines the severity of a collision. Further, the electronic control unit determines the state of a symmetric flag FRG through comparison between the front decelerations GI, Gr and the value of a front determination map boundary, serving as a front threshold variation pattern and through comparison between the floor deceleration Gf and the value of a low or high map boundary, serving as an activation threshold variation pattern. Then, on the basis of results of the severity determination and the state of the symmetric flag FRG, the electronic control unit determines a delay time in relation to the activation of the airbag unit. An airbag is expanded and deployed on the basis of the delay time.

摘要： A collision severity determining system for determining severity of a collision of a vehicle includes a first deceleration detector disposed in a central portion of a vehicle for detecting a deceleration in a longitudinal direction of the vehicle, and a second deceleration detector disposed in a front portion of the vehicle for detecting a deceleration in the longitudinal direction. A controller calculates a velocity change amount of the vehicle by integrating the vehicle deceleration with respect to time, and determines severity of the collision by comparing the vehicle deceleration with a threshold value corresponding to the same velocity change amount. When a problem, such as a failure or breakdown of the second deceleration detector, occurs, the severity determining unit operates in a predetermined fail-safe mode for selecting an appropriate severity determination map stored in the controller, and makes a severity determination based on the selected severity determination map.

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.
