  • Patent number: 9239380
    Abstract: A driver assistance system for avoiding collisions of a vehicle with pedestrians, the system including a camera sensor and/or a beam sensor. When an object moving at a given speed on a pedestrian crossing is detected, the object is detected as being a pedestrian with a probability that is sufficiently high to output a warning to the driver, reducing the likelihood of a potential collision.

  • Publication number: 20150336587
    Abstract: A driving assist device 1 includes: an information acquisition unit 20 that detects a driving operation of a driver for the vehicle; a driving skill evaluation unit 24 that evaluates a driving skill of the driver on the basis of a history of the driving operation of the driver; and a driving assist control unit 28 that performs the driving assist control for the vehicle on the basis of the traveling state of the vehicle and the target traveling state. When the information acquisition unit 20 detects the driving operation of the driver during the driving assist control, the driving assist control unit 28 limits the amount of driving assist control for the vehicle according to the driving skill of the driver evaluated and reflects the driving operation amount of the driver in traveling control for the vehicle.

  • Patent number: 8090492
    Abstract: The apparatus comprises a measured signal detector 11, a vehicle parameter obtainer 12, a sideslip angle temporary estimator 13, a sideslip angle differential corresponding value computer 14 and a sideslip angle real estimator 15. A sideslip angle temporary estimate value is computed from one or plural vehicle parameters including at least the mass. A sideslip angle differential corresponding value is computed from a measured signal and the vehicle parameters including no mass. A sideslip angle is derived from the sideslip angle temporary estimate value and the sideslip angle differential corresponding value. A sideslip can be detected without a steering angle detection mechanism.

  • Patent number: 7668635
    Abstract: A front wheel steering control device improves the handling and stability of a vehicle with respect to the steering wheel angles. The front wheel steering control device includes an input device for obtaining the steering wheel angle and the vehicle velocity, a first computing device for computing a yaw-rate for the vehicle which maintains the vehicle gravity center point sideslip angle at zero based on the steering wheel angle and the vehicle velocity that are obtained by the input device, a second computing device for computing a target front wheel actual steering angle for realizing the yaw-rate calculated by the first computing device, a control device for performing a steering control of the vehicle based on the target front wheel actual steering angle calculated by the second computing device. The ideal determination of the vehicle steering gear ratio and the derivative steering gain are relatively easy.

  • Patent number: 7517286
    Abstract: The invention is directed toward a trial golf club head and method for determining the optimal loft angle for any golf club, and in particular a hybrid-type golf club. The invention includes a trial golf club head having a face portion, a leading edge portion, a toe portion, a heel portion, a back portion having a trailing edge portion, and a sole portion. The sole portion contains a number of equally spaced graduated indicia, which are substantially parallel to one another and extend from the toe portion to the heel portion. The distance between the graduated indicia is approximately 3.75 centimeters (cm), which corresponds to an incremental loft angle of approximately 3 degrees. The sole portion has a radius of curvature of 71.67 mm, which extends from the leading edge of the face portion to the trailing edge of the back portion.
