摘要： A collision detection apparatus for a vehicle having a vehicle bumper, which includes a bumper reinforcement includes a chamber member, a pressure sensor, and a collision detecting device. The chamber member is provided inside the vehicle bumper at a front surface of the bumper reinforcement. The pressure sensor is configured to sense change of pressure in the chamber space. The chamber member includes a deformable part and a non-deformable part, each of which extends in a vehicle width direction. The deformable part is compressed to be deformed between the collision object and the bumper reinforcement in a case, where the collision object collides with the vehicle bumper. The non-deformable part is limited from being compressed to be deformed.

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： 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： A pedestrian collision detecting apparatus for motor vehicles is provided which works to distinguish between impacts with pedestrians and other sorts of impacts using a combination of a collision duration for which a sensor continues to sense a physical impact arising from collision with an object and a time-sequential change in locations of collisions of the vehicle with objects, thereby ensuring the reliability of detection of a pedestrian-vehicle collision and allowing the size and production costs of the apparatus to be minimized to improve the mountability of the apparatus in motor vehicles.

摘要： A pedestrian determining system mounted on a vehicle determines a collision object for protecting a pedestrian. An impedance sensor is included for detecting an alternating-current impedance or an electricity quantity being a function value of the alternating-current impedance to thereby output the detected one as an impedance signal, wherein the alternating-current impedance is varied by approaching of the collision object. A collision load sensor is included for detecting a collision load when the collision object collides with the vehicle to output the detected collision load as a collision load signal. Whether the collision object is a pedestrian or not is determined based on a value of a given function including as input variables the impedance signal outputted from the impedance sensor and the collision load signal outputted from the collision load sensor.

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： In a boundary line recognition apparatus, a boundary line candidate extracting part extracts boundary line candidates from image data obtained by an on-vehicle camera based on known image processing such as pattern matching and Hough transform. One or more kinds of boundary line feature calculating parts calculate one or more likelihoods of each boundary line candidate. The likelihood indicates a degree of probability to be the boundary line. A boundary line feature combining means multiplies the likelihoods of each boundary line candidate and outputs a combined likelihood. A boundary line candidate selecting part selects the boundary line candidate having a maximum likelihood as the boundary line. The boundary line feature calculating part further calculates the likelihood of the boundary line candidate using a dispersion of brightness and an internal edge amount, and changes the likelihood based on an additional likelihood obtained by a driving lane surface feature extracting part.

摘要： A pedestrian collision detection apparatus includes a bumper sensor, an acceleration sensor, a vehicle speed sensor, and a controller. The controller calculates an effective mass based on outputs from the bumper sensor and the speed sensor. The controller calculates a velocity change based on an output from the acceleration sensor. Further, the controller includes a two-dimensional map, which contains an effective mass and a velocity change and defines a pedestrian area for collision with a pedestrian. The controller determines a collision with a pedestrian when the pedestrian area contains a point determined by the calculated maximum effective mass and maximum velocity change. It is therefore possible to accurately distinguish a collision between the vehicle and the pedestrian from collision with the other object to reliably detect the collision.
