20090276124 | Vehicle stability control device - There is provided a new and novel vehicle stability control device through steering wheels independently of the driver's handling operation, in which a suitable steering angle parameter in determining a target value for a turning state parameter is selected. The control device calculates a provisional target steering angle for wheels based upon an amount of an operation of a driver and a predetermined steering characteristic; a target value for the turning state parameter; and a target steering angle for wheels for reducing a magnitude of a deviation of the actual turning state parameter from its target value when the magnitude of the deviation is at a reference value or above, and thereby controlling a steering angle based upon the target steering angle. During execution of controlling the steering angle based upon the target steering angle, the target value of the turning state parameter is calculated based upon the provisional target steering angle. | 11-05-2009 |

The right and left braking force difference estimating unit estimates difference between the braking forces to be imposed on the right and left wheels each estimated by the braking forces estimating unit. The assist steering torque providing unit provides an assist steering torque for the steering torque controlling unit on the basis of the difference in braking force between right and left wheels estimated by the right and left braking force difference estimating unit. | 06-24-2010 |
20130030665 | METHOD AND APPARATUS FOR VEHICLE SWAY DETECTION AND REDUCTION - A method and apparatus for controlling a vehicle involves determining if the vehicle is swaying and if the vehicle is swaying, reducing a torque of an engine of the vehicle and/or applying independent braking forces to each wheel of the vehicle. A vehicle for controlling vehicle sway includes an engine, a plurality of wheels, a braking system configured to apply independent braking forces to each wheel, and a controller configured to control the engine and the braking system. The controller is configured to determine a correlation coefficient in accordance with any phase shift occurring between a yaw acceleration signal and a lateral acceleration signal. The correlation coefficient is compared to a threshold value to determine whether the vehicle is swaying. If the vehicle is swaying, the controller causes a torque of the engine to be reduced and/or braking forces to be applied independently to each wheel. | 01-31-2013 |

20110237176 | AIR CONDITIONER REGISTER - An air conditioner register includes a downstream retainer portion, a barrel pivotally mounted in the downstream retainer portion to change the flow direction of air for air conditioning, and a pair of guide fins. First outer surfaces of the barrel extend along first inner surfaces of the downstream retainer portion. The barrel is supported pivotally about a pivot shaft extending in the direction perpendicular to a second inner surface of the downstream retainer portion. Each of the guide fins guides air for air conditioning into the opening of the barrel upstream in the airflow direction. Together with pivoting of the barrel from its neutral position, one of the guide fins is moved together with the barrel to a position between the barrel and a portion of the first inner surface of the downstream retainer portion from which the opening of the barrel upstream in the airflow direction becomes separated as the barrel pivots. | 09-29-2011 |
20140080399 | AIR CONDITIONING REGISTER - An air conditioning register includes a downstream fin, primary upstream fins, a secondary upstream fin, and an operation knob slidably attached onto the downstream fin. The operation knob sandwiches a shaft of the secondary upstream fin. The air conditioning register has a link mechanism that includes arms and a coupling rod. The arms extend from pivots of the primary and secondary upstream fins in a direction orthogonal to the pivots, and have a pin at the tip of the arms. The coupling rod couples the respective pins. The distance between the pivot and the pin in the arm of the secondary upstream fin is longer than the distance between the pivot and the pin in the arm of each primary upstream fin. The coupling rod includes coupling portions, each of which couples the pins of an adjacent pair of the arms. Adjacent coupling portions are pivotally coupled. | 03-20-2014 |
20140120826 | AIR CONDITIONING REGISTER - An air conditioning register is provided that includes a case, a downstream fin, a specific upstream fin extending in a direction perpendicular to the downstream fin, and an operation knob.
