  • Patent number: 7680576
    Abstract: To maintain operating safety by driving force distribution control system when an abnormal state arises and to smoothly transition from a normal state to an abnormal state without sudden changes in vehicle behavior. The driving force distribution control part calculates the transfer torque for the transfer clutch for the center differential device and the torque movement for the hydraulic motor for the rear wheel final reduction gear. When the control state detection part detects an abnormal state, there is control of the hydraulic motor in the direction that torque movement is lost on the one hand, and the transfer torque for the transfer clutch is controlled in the direction of front and rear distribution; after a preset time and after this control is carried out, the transfer torque drops.

  • Publication number: 20090037053
    Abstract: A basic-additional-yaw-moment setting section sets a basic additional yaw moment and determines the polarity of the basic additional yaw moment on the basis of a steering-wheel angle, a yaw rate, and a vehicle speed. A left-right driving-force distribution controller sets the driving-force distribution with respect to left and right driving wheels on the basis of the basic additional yaw moment and the polarity of the basic additional yaw moment, and adjusts the driving-force distribution when a vehicle drive control operation signal is output from a vehicle drive control unit. Specifically, the left-right driving-force distribution control section adjusts the driving-force distribution such that the polarity of the basic additional yaw moment is in the same direction as that of a yaw moment applied by the vehicle drive control unit.

  • Publication number: 20080242674
    Abstract: The present invention provides medicines useful for the prevention or treatment of urinary frequency or incontinence. That is, the present invention relates to a medicine comprising combination of a phenoxyacetic acid derivative represented by the following general formula (I) (wherein R1 represents a hydroxy group or a lower alkoxy group) or a pharmaceutically acceptable salt thereof, or a hydrate or solvate thereof and an ?1 adrenoceptor blocker, which exerts an excellent effect decreasing intra-bladder pressure or prolonging micturition interval and useful for the prevention or treatment of urinary frequency or incontinence.

  • Publication number: 20060169523
    Abstract: The present invention offers a power steering device for a four-wheel drive, which includes: a first self-aligning torque estimation unit for estimating a self-aligning torque generated in a current vehicle behavior as a first self-aligning torque; a second self-aligning torque estimation unit for estimating a self-aligning torque that is to influence a subsequent vehicle behavior as a second self-aligning torque; a self-aligning torque change amount calculation unit for calculating a difference of the second self-aligning torque from the first self-aligning torque as a self-aligning torque change amount; and an assisting force correction unit for determining and outputting a corrected value of an assisting force to be generated for a steering operation based on the self-aligning torque change amount.

  • Patent number: 7029415
    Abstract: A differential apparatus having a limited slip differential mechanism which comprises a differential case, a pair of side gears housed in the differential case and connected to driving shafts, and pinion gears meshing with the pair of side gears. One of the tooth surfaces of each tooth of the side gears and the pinion gears has a large pressure angle and the other surface has a small pressure angle, such that meshing reaction forces Dr in a drive mode is larger than that of Co in a coast mode to obtain different limiting forces.
