摘要： PROBLEM TO BE SOLVED: To provide a suspension device for improving the safety performance of a vehicle.
SOLUTION: When an overturn predicting part (a behavior predicting means) predicts the overturn of the vehicle, a semiactive suspension control device 11 (a control means) closes a cutoff valve to a turning inner ring to change a shock absorber 2 opposed to the turning inner ring into a rigid form. This suppresses the flotation of the vehicle body at its turning inside during turn by the spring force of the turning inner ring to avoid the overturn of the vehicle, thus improving the safety performance of the vehicle.

摘要： PROBLEM TO BE SOLVED: To enhance turning performance by adjusting a damping force of a shock absorber, in a vehicular suspension control device.
SOLUTION: Damping force characteristics of shock absorbers of wheels 2R, 2L and 3R, 3L are adjusted by a controller based on lateral acceleration detected by a lateral acceleration sensor. During a turn, the damping force characteristic of the front wheel 2R at the outer turning side is set to be S/H (elongation side: soft/contraction side: hard), the damping force characteristic of the front wheel 2L at the inner turning side is set to be H/S (elongation side: hard/contraction side: soft), and the damping force characteristics of the rear wheels 3R, 3L at both sides are set to be H/H (elongation side: hard/contraction side: hard), respectively. Cornering forces of the front wheels 2R, 2L are increased, and angles of side slips of the rear wheels 3R, 3L are increased. As a result, a yaw rate is increased, and the turning performance can be enhanced.

摘要： PROBLEM TO BE SOLVED: To reduce energy consumption by a simple structure in a suspension control device.
SOLUTION: Left and right suspension units 2 of the vehicle are connected to each other through a dual-direction hydraulic pump 3. A motor 4 for driving the dual-direction hydraulic pump 3 is controlled by a controller 6 based on the vehicle state detected by a lateral acceleration sensor 11, a steering angle sensor 12 and a vehicle height sensor 17, and rolling of the vehicle body at turning is suppressed by transferring an oil liquid between the left and right suspension units 2. At this time, in the controller 6, high-pass filter processing is performed relative to a control signal based on detection of the vehicle height sensor 17. Thereby, the control signal of low frequency can be cut relative to steady inclination of the vehicle body due to variation of loading load caused by getting in/out of an occupant, unnecessary attitude control is prevented from being performed and energy consumption can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a suspension control device capable of simplifying a constitution and realizing the control of high accuracy by individually calculating the control command value for a shock absorber ready for four wheels while employing only one sprung acceleration sensor.
SOLUTION: A four-wheel sprung acceleration computation unit 28 computes the sprung acceleration of four wheels from the respectively detected data of a sprung acceleration sensor 1 for detecting the sprung acceleration at one part of a vehicle body 14, a first coefficient multiplication unit 2 and a second coefficient multiplication unit 27. Further, a four-wheel relative velocity computation unit 30 calculates the four-wheel relative velocity, and a controller 20 obtains the damping force command value for the skyhook control to each shock absorber of the four wheels by using the four-wheel relative velocity. Since the control command value to be used for the skyhook control can be individually calculated to each shock absorber ready for four wheels by using one sprung acceleration sensor 1, the constitution can be simplified in comparison with the conventional technology having two or more sprung acceleration sensors.

摘要： PROBLEM TO BE SOLVED: To improve the traveling stability of a vehicle by integrating a vehicle stability control device for controlling distribution of a driving force to each wheel and heightening stability of the vehicle with a suspension control device for controlling a posture of a vehicle body.
SOLUTION: This vehicle stability control device cancels oversteering and heightens traveling stability, for example by increasing distribution of a driving force of a rear wheel 2L on the turning inside at the time of oversteering to generate a turning outward yaw moment. At that time, a control for heightening a vehicle height is executed to the rear wheel 2L, whose distribution of a driving force is increased, by the suspension control device, so as to increase a wheel load of the rear wheel 2L. Thereby, a maximum friction force between the rear wheel 2L and a road can be increased, so as to heighten a control effect by the distribution of the driving force of the vehicle stability control device.

摘要： PROBLEM TO BE SOLVED: To provide a suspension control device capable of assuring an improvement in braking performance at a sudden brake over an extended time period by increasing a wheel load while retaining the stroke of an actuator.
SOLUTION: When the braking condition of a vehicle 2 is a sudden brake, a correction normal control signal 28 obtained by adding a braking control signal 27 and a normal braking signal 26 is output to a hydraulic cylinder 13 to generate thrust. Due to the expansion/contraction control of the hydraulic cylinder 13 based on the correction normal control signal 28 including the braking control signal 27, the wheel load is increased/decreased when the thrust is generated. By the expansion control of the hydraulic cylinder 13, the wheel load is increased, the braking performance is improved, and a braking distance is shortened. By the contraction control of the hydraulic cylinder 13, the expanded condition of the cylinder 13 is suppressed, the stroke is assured, and consequently, the braking performance can be improved over an extended period of time.
