    摘要: A drive force control method for a four-wheel drive vehicle including a torque distributing mechanism capable of changing a drive force distribution ratio between front and rear wheels and a drive force distribution ratio between right and left front wheels or between right and left rear wheels. This method includes the steps of increasing the drive force distribution ratio of the rear wheels to the front wheels according to an increase in absolute value of a lateral G signal, and increasing the drive force distribution ratio of a turning outer wheel as one of the right and left front wheels or one of the right and left rear wheels to a turning inner wheel as the other. A lateral G sensor signal is corrected by an estimated lateral G signal calculated according to a steering angle and a vehicle speed to obtain a control lateral G signal, which is used as the lateral G signal.

    摘要: In a vehicular driving force distribution system, a left or right torque distribution clutch is selectively engaged to lock a carrier member or a sun gear of a planetary gear mechanism, whereby torque can be distributed between left and right wheels. Also, if a differential limitation clutch is engaged to control relative rotation of the sun gear and the carrier member of the planetary gear mechanism, the planetary gear mechanism enters a locked state, so that the left and right wheels are integrated to perform differential limitation. By the arrangement of merely providing the differential limitation clutch, the differential limitation can be performed by simple control and moreover the control response is improved, as compared with the case where differential limitation is performed by controlling engagement forces of the left and right torque distribution clutches.

    摘要: A vehicle co-operative control system is provided which suppresses the torque steer phenomenon by co-operatively controlling a driving force and/or braking force distribution device and an electric power steering device without changing the control device of the electric power steering device for a vehicle having a specification in which the co-operative control is not carried out or with the introduction of only a minimal change. The control device can also be applied to a vehicle having a specification in which the co-operative control is carried out. In order to achieve this, the steering torque detected by the steering torque detecting device is input into a corrected steering torque calculating device of a first electronic control unit for controlling the driving force and/or braking force distribution device and a corrected steering torque which has been calculated in the corrected steering torque calculating device is input into the second electronic control unit for controlling the electric power steering device. The second electronic control unit controls the electric power steering device based on the corrected steering torque and thus the torque steer phenomenon caused by the driving force and/or braking force distribution device is suppressed.

    摘要: A small-sized damper is provided which enables to effectively vary the damping force of a damper even in a region in which the moving speed of a rod is small. On one of a damper main body and a rod which is inserted into the damper main body, there are mounted a magnet coil having a winding axial line which is coaxial with the damper, and magnetizable attracting members. By electric charging to the magnet coil, the magnetizable attracting members are attracted into contact with the other of the damper main body and the rod.

    摘要: A suspension system for a steered wheel includes a knuckle for steerably supporting the steered wheel about a king pin axis, and upper and lower arms pivotally supported on a vehicle body and connected at free ends thereof to upper and lower portions of the knuckle, respectively. This suspension system further includes a link mechanism which includes a first substantially vertically extending rod connected to the knuckle at a location more inward of the vehicle body than the king pin axis, and a second rod connected at one end to the first rod and at the other end to at least one of the vehicle body and the lower arm. A resilient device is connected to the link mechanism and adapted to exhibit a resilient force repulsive to the deformation of the link mechanism. Thus, even if the king pin offset is set at a small value, a restoring torque can be sufficiently insured in the steering device when steering through a large steering angle at a low speed.

    摘要: A drive wheel torque control system for a vehicle includes control means for controlling a variable differential motion limiting device provided between drive wheels to distribute a predetermined LSD torque from a racing drive wheel to a nonracing drive wheel. The control means includes vehicle speed determining means for determining a vehicle speed from a follower wheel spaced, drive wheel speed determining means adapted to select a smaller one of the drive wheel speeds as a drive wheel speed, when the inner-side wheel in turning movement is racing, and to select a larger one of the drive wheel speeds, when the outer-side wheel in turning movement is racing, and torque determining means for determining the LSD torque from the vehicle speed and the drive wheel speed. This ensures that only when the inner wheel is racing, the smaller one of the drive wheel speeds can be selected, and an LSD torque can be distributed to the outer wheel, thereby easily effecting the adjustment of the locus of turning movement of the vehicle when the inner wheel is racing, while properly controlling the behavior of the vehicle.

    摘要: The distribution of drive power produced by a drive power source is controlled in a four-wheel-drive motor vehicle having main drive wheels and auxiliary drive wheels. Drive powers produced by the drive power source are independently regulated and transmitted to the left and right auxiliary drive wheels. While the drive power distribution ratio between the main and auxiliary drive wheels is maintained at a suitable value, the drive powers are variable distributed between the left and right auxiliary drive wheels by a drive power distribution control system. The drive power distribution control system determines the drive power distribution ratio between the left and right auxiliary drive wheels depending on a detected lateral acceleration exerted to the motor vehicle, and transmits the drive powers to the left and right auxiliary drive wheels according to the determined drive power distribution ratio.
