    摘要： PROBLEM TO BE SOLVED: To provide a vehicle body attitude control apparatus capable of improving cornering operability, steering stability, and a ride comfort while a vehicle is running.SOLUTION: A controller 13 includes a gain 16, a determination unit 17, a multiplication unit 18, an FF control unit 19, a difference calculation unit 20, an FB control unit 21, an average value calculation unit 22, a target damping force calculation unit 23, and a damper instruction value calculation unit 24 so as to enable such control that a pitch rate and a roll rate are set into a proportional relationship while the vehicle is cornering. The controller calculates a target pitch rate proportional to the roll rate, variably controls a damping force characteristic of a damping force variable dampers 6, 9 disposed at each of front left, front right, rear left, and rear right wheels so as to achieve the target pitch rate, and generates a pitch moment to be applied to the vehicle body accordingly.

    摘要： PROBLEM TO BE SOLVED: To provide a steering control device mounted on a vehicle which is electrically steer-controlled capable of establishing the stabilization etc. of a body behavior when the vehicle turns.
    SOLUTION: A steering ECU 7 calculates a roll rate presumed value Rre on the basis of a steering angle δ and lateral acceleration Gy fed from a lateral G sensor 16 at a step S4, and then at a step S5, sets a front-wheel side vehicle speed gain Kf and a rear-wheel side vehicle speed gain Kr on the basis of vehicle speed v using a map and/or a function. Then the steering ECU 7 calculates a front-wheel side steering correction value Sfc by multiplying the roll rate presumed value Rre by the front-wheel side vehicle speed gain Kf at a step S6, and then at a step S7, calculates a rear-wheel side steering correction value Src by multiplying the roll rate presumed value Rre by the rear-wheel side vehicle speed gain Kr.

    摘要： PROBLEM TO BE SOLVED: To provide a vehicle body posture control system capable of enhancing turning operability, operation stability and ride comfort during vehicle traveling.SOLUTION: While a tire is in a working region during vehicle traveling, a pitch control section 23 which calculates a target pitch rate according to a roll rate takes precedence over a roll restraining section 18. In this case, a target damping force calculated by the pitch control section 23 is weighted and damping force characteristics of respective dampers 6, 9 are controlled to obtain the target pitch rate. In a limited region where a road surface grip state of a tire is poor, a roll restraining section 18 takes precedence over the pitch control section 23 to weight the target damping force calculated by the roll restraining section 18. Thus, damping force characteristics of respective dampers 6, 9 are controlled to increase roll restraining controlled variables.
