摘要： A load sensor includes a optical fiber sensor that provides output analog signals in response to shocks of various magnitudes caused by hits by a vehicle on various objects, two or more amplifiers each of which approximates a non linear function of the analog signals and a unit that converts the linear functions into digital data. Therefore, each analog signal either in a lower magnitude range or a higher magnitude range can be amplified by one of the amplifiers that has a more suitable gain, so that the magnitude of the shock can be accurately converted into digital data for a pedestrian protection airbag system.

摘要： From a collision load, a one-time integration value and a two-time integration value are computed. The one-time integration value and two-time integration value are then used for obtaining a mass and rigidity of a collision object as two primary parameters. The obtained two primary parameters are used for determining whether or not the collision object is a pedestrian. This achieves accuracy in determining the collision object that is remarkably superior to a conventional method that uses a collision load waveform.

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 sensing device comprise an inner member provided at a front part of a vehicle and a load sensor provided at a position before a front of the inner member, in addition to an outer member and a load transfer member. The outer member is provided at the front part of the vehicle so as to be located more frontward than the load sensor so that a space is formed between the outer member and the load sensor. The outer member is in charge of allowing the load sensor to sense, via the outer member, a load applied to a front of the vehicle. The load transfer member, made of a hard material, is disposed adjacently to the load sensor within the space between the outer member and the load sensor. The load sensor is allowed to move along the inner member in the back-and-forth direction of the vehicle.
