摘要： A vehicle body attitude control apparatus capable improving cornering operability, steering stability, and 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 the wheels so as to achieve the target pitch rate, and generates a pitch moment to be applied to the vehicle body.

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.

摘要： A vehicle attitude controller capable of improving turning operability, steering stability, and ride quality of a vehicle. In a normal-operation region, a pitch control unit for calculating a target pitch rate in accordance with a roll rate performs control in priority to a roll suppression section. In this case, a target damping force calculated in the pitch control unit is weighed to control a damping-force characteristic of the dampers so that a pitch rate becomes equal to the target pitch rate. In a critical region in which a road-surface gripping state of the vehicle tires is bad, the roll suppression section performs control in priority to the pitch control unit so as to weigh a target damping force calculated in the roll suppression section. As a result, the damping-force characteristic of the dampers is controlled so as to increase the amount of roll suppression control.

摘要： [Object]The present invention provides a suspension control apparatus that allows miniaturization of a solenoid valve.[Solution]When a controller is started up by a power source controller (a power source unit), the controller switches a control current from 0 ampere to a maximum current value I6 at the same time as the startup. After that, the control shifts to normal control. As a result, even if a hysteresis of a damping force characteristic is large relative to the control current, it is possible to promptly move a solenoid valve to a position to be used in the normal control.
