摘要:
The present invention provides a vehicle body attitude control apparatus capable of improvement of cornering operability, steering stability, and a ride comfort while a vehicle is running. A controller includes a gain, a determination unit, a multiplication unit, an FF control unit, a difference calculation unit, an FB control unit, an average value calculation unit, a target damping force calculation unit, and a damper instruction value calculation unit 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 damper 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:
Provided is a suspension control apparatus for a vehicle comprising a damping-force adjustable shock absorber interposed between a vehicle body and a wheel of a vehicle, and a controller for variably controlling damping-force characteristics of the damping-force adjustable shock absorber between hard and soft, wherein the controller is configured to switch the damping-force characteristics to a soft side when a direction of a stroke of the damping-force adjustable shock absorber is reversed between an extension stroke and a contraction stroke.
摘要:
Shock absorbers of left and right front wheel suspensions and shock absorbers of left and right rear wheel suspensions each are constituted by a damping force adjustable hydraulic shock absorber provided with a frequency response unit. An actuator of a damping force variable mechanism provided to the shock absorber is driven and controlled by a controller. The controller variably adjusts the damping force between the soft side and the hard side by the damping force variable mechanism according to a vertical vibration when a vehicle body vertically vibrates at a low frequency. The controller does not adjust the damping force when the vehicle body vibrates at a higher frequency than the low frequency.
