    摘要： In a passenger judging apparatus with a load sensor excellent in practical use and capable of achieving not only the reduction of judgment delay in the case of the necessity for a quick judgment but also the improvement of the judgment accuracy in the other cases, a judgment indicating the occurrence of a state transition forming a transition between classes is made only when a load detected stays continuously in a predetermined class for a predetermined threshold time period, with the threshold time period being variably set to be different in length among inter-class state transitions. This contributes greatly to the improvement of the judgment accuracy by eliminating erroneous judgment stemming from a false signal without uselessly delaying the judgment on the state transition requiring a quick decision.

    摘要： The present invention provides a seated person determination apparatus for a vehicle seat that accurately differentiates the type of person seated, or differentiates a person seated from an object such as a child seat. This is accomplished by utilizing the shape of the standard surface distribution of the load that simulates the shape of contact surface formed between the human buttocks and the surface of seat pad. Specifically, the present invention provides a seat sensor composed of the plurality of sensor portions placed in a seat pad of a vehicle seat distributed in a plane parallel with the surface of the seat. The load exerted on the surface of the seat by a person seated or an object placed on the seat is detected by the plurality of sensor portions of the seat sensor located in corresponding position.

    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： 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： 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.
