  • Patent number: 7997613
    Abstract: Multiple protecting devices, such as an air bag and an air bag jacket, are controlled and operated in accordance with the shape and size of an impact. A normal collision determining section causes the air bag and/or the air bag jacket to operate in accordance with the magnitude and direction of a collision based on outputs of G sensors. When a collision predicting section predicts a collision on the basis of other vehicle information obtained by a vehicle-to-vehicle communication device and own-vehicle information, it causes a stand-by collision determining section to start instead of the normal collision determining section. The stand-by collision determining section determines a collision mode in advance and sets a threshold value for determining the outputs of the G sensors to a value different from a value used in the determination of the normal collision determining section so as to permit quick determination of a collision.

  • Patent number: 7996132
    Abstract: A method and a system of controlling a restraint device in a vehicle during a crash. The method includes sensing a lateral acceleration without using other vehicle dynamic information. The method also includes integrating the sensed lateral acceleration to determine a change in (or delta of) lateral velocity, low-pass filtering the sensed lateral acceleration, and extrapolating the delta lateral velocity and the filtered acceleration to estimate a vehicle lateral velocity. The method also includes sensing a vertical acceleration, integrating the sensed vertical acceleration, combining the integrated vertical acceleration and the predicted vehicle lateral velocity to give an indication of how severely the vehicle laterally hits an obstacle, and generating a deployment signal to activate the restraint device.

  • Patent number: 7845678
    Abstract: An airbag is inflated by gas for deployment to the front of and for restraining an occupant. A tether allows an inner capacity of the airbag to be equal to or smaller than a predetermined value by restricting a distance between a proximal end of the airbag and a surface of the airbag at deployment. A control unit acquires information relating to at least one of an occupant seat position, an occupant position to an instrument panel, an occupant physique, an occupant weight, and a magnitude of a collision impact. A release unit controls capacity and configuration of the airbag by releasing an end of the tether at a side of the proximal end according to the information acquired by the control unit. A vent discharges the gas before activation of the release unit and is closed on activation of the release unit.

  • Patent number: 7840026
    Abstract: An apparatus for detecting an object is provided which detects the pitching of a vehicle, and detects the presence of an object the front of the vehicle itself with the pitching being taken into consideration. The apparatus includes a microcomputer that performs image processing for the image of the object to compute the velocity and acceleration of the object present in the picked-up image, and based on the computed acceleration of the object, to determine whether the image was captured when the vehicle itself was balanced. If the image is judged to be an image captured when the vehicle itself was not balanced, then the position of the object present in the picked-up image is computed based on another picked-up image that was captured when the vehicle itself was balanced.
