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: 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: In a vehicle bumper structure, an optical fiber sensor (32) is provided on the upper portion of the front surface of a front wall portion (30A) of a front-bumper reinforcement (30). A front-bumper absorber (28) is provided before the optical fiber sensor (32) and a load transfer plate (34) is disposed between the front-bumper absorber (28) and the optical fiber sensor (32). The vertical width (B3) of the front-bumper absorber (28) and the load transfer plate (34) are greater than the vertical width (B1) of the optical fiber sensor (32), and a lower end portion (34A) of the load transfer plate (34) extends below the lower end of the optical fiber sensor (32). Accordingly, when the optical fiber sensor (32) is offset to the upper portion of the front-bumper reinforcement (30), the front-bumper absorber (28) will not topple down and the impact load is input to the optical fiber sensor (32) even if the input direction of the impact load is slightly inclined.

摘要: A vehicular pedestrian collision detection sensor detects a collision with a pedestrian which allows high-accuracy recognition of a collision with a pedestrian. A large number of load detection cells are arranged in a lateral direction (width direction) of the front side of a vehicle. The total collision load is calculated with respect to a cell group composed of some of the load detection cells which are adjacent to each other, wherein the cell group has a width generally equal to a pedestrian width. Based on the total collision load, an amount correlated to the mass of a pedestrian is calculated. When the amount correlated to the pedestrian mass is within a preset range, a collision with a pedestrian is recognized or determined.

摘要: A collision-detecting device according to the present invention is installed in a bumper of an automotive vehicle. The collision-detecting device includes a deformable member disposed behind a bumper cover, a pressure sensor disposed in an inside space of the deformable member and an electronic control unit for determining a collision with a pedestrian based on signals from the pressure sensor. A width of the deformable member is made 300 mm or wider so that the width sufficiently covers a portion that is usually deformed by a collision with a pedestrian. A height of the deformable member is so set that a reaction force of the deformable member generated by a collision with a pedestrian does not exceed a predetermined level such as 1 kN. According to the present invention, a collision with a pedestrian is surely detected and the colliding pedestrian is protected from a severe damage.

摘要: An impact sensor includes the first and the second electrodes arranged a predetermined distance away from each other in a tube insulator. The impact sensor is arranged at a front of a vehicle such that the first and the second electrodes opposed to each other in the front-to-rear direction of the vehicle. The first and the second electrodes include cable conductors sheathed with elastically deformable conductive members, respectively. The first and the second electrodes are apart from each other when no impact is applied to the impact sensor. When a collision occurs and the impact is applied to the impact sensor, a contact area between the conductive members increases and a resistance between the first and the second electrodes continuously decreases.

摘要: In a collision damage reduction system, a microcomputer obtains relative position data corresponding to a relative between a vehicle and an object from a first detecting unit, the detected speed of the vehicle as detected by a second detecting unit, the detected turning angle of the vehicle as detected by a third detecting unit. The microcomputer calculates a total collision probability representing a probability that the vehicle and the object will collide on a runnable space according to the relative position data, the detected speed of the own vehicle and the detected turning angle. In addition, the microcomputer instructs the operation unit to operate at least one of a first collision avoidance operation and a second collision avoidance operation according to the total collision probability.

摘要: An in-vehicle white line recognition apparatus is disclosed. Form an image captured by a camera, the apparatus extracts multiple white line candidates including a first white line candidate and a second white line candidate. The apparatus calculates a certainty factor of each white line candidate, the certainty factor indicating a degree of certainty that the each white line candidate represents the white line. When the first and second white line candidates are within a predetermined range and when a ratio of contrast of the first white line candidate to that of the second white line candidate is less than a predetermined value, the apparatus decreases the certainty factor of the first white line candidate.
