摘要： Upon searching control parameter used to adjust damping force of a damper from a map in accordance with damper speed and target damping force decided based on moving condition of the vehicle, the map sets the control parameter, which are relatively higher than the actual damping force characteristics, as map data in the area where the damper speed is less than a predetermined value, the area where the noise has the great influence on the sensor outputs. Therefore, it can be prevented that the control parameter of the damping force is varied largely or varied in a short period by the influence of noise, and the driving stability control of the vehicle can be executed exactly and the noise caused by switching the damping force of the damper can be reduced.

摘要： A damper with a controllable variable damping force, includes a piston and a cylinder provided with a magnetic viscous fluid and piston therein. An interior of the cylinder is divided by the piston into first and second fluid chambers which communicate with each other. A controller energizes a coil provided to the piston, wherein a viscosity of the magnetic viscous fluid in the fluid passage is changed when the coil is energized. When the controller fails to energize the coil, an electric current supply circuit supplies a predetermined constant electric current to the coil. Alternatively, when the controller detects an abnormality in energizing control of the coil, the controller supplies the predetermined constant electric current to the coil. Further, a sub-coil may be provided with the piston, wherein the controller supplies the sub-coil with a predetermined constant electric current whenever the coil is not operating properly.

摘要： In a suspension control system, accelerations detected by acceleration sensors are differentiated by a differentiator to calculate acceleration derivative values. Based on these values, a target electrical current calculating section calculates a target electrical current that is supplied to an actuator which controls a damping force of a damper. Before a rolling or pitch angle occurs in the vehicle, the change of the rolling or pitch angle is predicted to control the damping force of the damper, thereby improving the response of rolling angle and pitch angle control to achieve, simultaneously, an accurate posture control and a satisfactory riding comfort. Because the target electrical current calculating section corrects the target electrical current of the actuator based on a damper speed obtained by differentiating a damper displacement, even when a large input is applied to the damper due to an unevenness of the road surface, a proper posture control is performed.

摘要： An active suspension system and an active suspension control method for a vehicle having a first wheel set and a second wheel set, comprising a power actuator interposed between the vehicle body and each of the wheels; a sensor for detecting turning maneuver of the vehicle; and a control unit for controlling operation of the actuators according to data obtained from the sensor so as to reduce a vertical load acting on the inner wheel of the second wheel set which bears a less vertical load than the first wheel set during the turning maneuver. Thereby, the shifting of the vertical load between the wheels of the first wheel set is reduced with the result that the overall cornering force of the vehicle is maximized because of the saturating property of the maximum cornering force of the tire in relation with the vertical load acting thereon.
