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 provide a brake control device capable of suppressing the behavior in a large behavior of a vehicle.
SOLUTION: When a pitch behavior where a front part of a vehicle body rises becomes large, a deformed pitch angular velocity α dθ/dt becomes not larger than a predetermined value j01, a brake signal F for behavior control output by a brake signal calculation circuit 14 for behavior control is input to an actuator 17 as a target braking force signal K, a brake means 19 for a front wheel generates the braking force according to the brake signal F for behavior control. Load movement in the forward direction is generated in the vehicle body thereby and the pitch behavior is suppressed. Since the suppression of a pitch movement is not performed by the operation of a shock absorber, but is performed by braking the wheel, the suppression of a large pitch behavior can be performed by responding to a large pitch behavior where the shock absorber is fully stroked, and the suppression of the pitch movement become a difficult state depending on the shock absorber.

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 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.
