摘要： PROBLEM TO BE SOLVED: To set a damping force on extension side/retraction side to soft/soft in a fail state in a damping force variable hydraulic damper capable of adjusting the damping force on the extension side/retraction side to hard/soft, soft/soft, or soft/hard.
SOLUTION: Spring forces of bias springs 38 and 41 and a shape memory alloy spring 43 are applied to a spool 27 for adjusting damping force, and the damping force is adjusted by moving the spool 27 against these spring forces by a proportional solenoid 35. The shape memory alloy spring 43 is electrically connected in series to the coil 44 of the proportional solenoid 35. The shape memory alloy spring 43 is heated by the energization of the coil 44 in a normally operating state to extend so as to act as the return spring of the spool 27. In the fail state, the energization of the coil 44 is stopped to lower the temperature of the shape memory alloy spring 43, and the shape memory alloy spring tends to be easily deformed. Accordingly, the shape memory alloy spring is compressed by the bias springs 38 and 41 to move the spool 27 so as to set a damping force to a proper damping force.

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.

摘要： PROBLEM TO BE SOLVED: To provide a suspension control device capable of enhancing the durability as the entire suspension control device by changing the control pattern to reduce the load on an actuator when the changing operation lasts highly frequently for a long time.
SOLUTION: When using a shock absorber having the inversion type damping force characteristic, the load on an actuator is increased during the unsprung control which is preferable for the traveling on a rough road. The continuing time of the unsprung control is measured by a rough road counter (212), and when the counted value of the rough road counter exceeds the set value, the offset control in which the load on the actuator is lower than the unsprung control is selected (218, 222).

摘要： PROBLEM TO BE SOLVED: To provide a suspension control device for improving the control effects of unsprung vibration.
SOLUTION: In the suspension control device, a skyhook command signal B based on speed data obtained by integrating sprung acceleration αu from a sprung acceleration sensor 9u is added to an unsprung vibration damping command signal C based on unsprung acceleration αd detected by an unsprung acceleration sensor 9d to form a control signal A for a shock absorber 6 having reversible type damping property. The control signal A is formed so that the unsprung acceleration αd having a phase advancing 90° is reflected to a piston speed. This allows compensation for a response delay due to an actuator 11 to improve the control effects accordingly and to consequently improve the controllability and stability of a vehicle.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic suspension control device having a simple configuration which can improve gas mileage.
SOLUTION: The coil 15 of the electromagnetic damper 3a on the left side is connected to the coil 15 of the electromagnetic damper 3b on the right side through the medium of first and second switches 25a, 25b on the left side, a switch 21 on the right side, and a variable resistor 2. By adjusting the switching between the ON positions and the OFF positions of the first and second switches 25a, 25b on the left side and the switch 21 on the right side, and by adjusting the magnitude of the resistance value of the variable resistor 22 in accordance with a road surface condition, the oscillation control mode can be changed. Because of this, a favorable ride can be secured in accordance with a road surface condition. For example, the oscillation control mode can be continuously changed by continuously changing the resistance value of the variable resistor 22, and the generation of an impact associated with the switching of the oscillation mode can be prevented. The power which is generated by the electromagnetic damper can be used for a power source of another electromagnetic damper at the time of control of oscillation, and the constitution can be made simple as compared with the case where another battery or another supply source of external energy is provided.

摘要： PROBLEM TO BE SOLVED: To prevent a response delay of damping force when a stroke direction of a piston rod is switched in a damping force type hydraulic shock absorber.
SOLUTION: When a piston rod 6 in the stroke of extension, a damping force is generated by controlling oil flow from a cylinder upper chamber 2A to a reservoir 4 with an extension side damping force adjustment mechanism 30. In this case, since the oil is made to flow without resistance from the reservoir 4 to a cylinder lower chamber 2B with an extension side check valve 62, when being switched to contraction stroke, the response delay is not generated because a pressure of the cylinder lower chamber 2B rises quickly. In the contraction stroke of the piston rod 6, the damping force is generated by controlling the stream of the oil from the cylinder lower chamber 2B to the reservoir 4 with a contraction side damping force adjustment mechanism 31. In this case, since the oil is made to flow from the reservoir 4 to the cylinder upper chamber 2A with a contraction side check valve 57, when being switched to the extension stroke, the response delay is not generated because a pressure of the cylinder upper chamber 2A rises quickly.

摘要： PROBLEM TO BE SOLVED: To provide a suspension control device capable of assuring favorable travelling stability for a vehicle even when an alarm is generated.
SOLUTION: When an automobile 2 comes too close to a center line, and the content of a center line leaning information 101 indicating the degree of bias of the automobile 2 from the center line is at or below a center line biasing reference value, a center line biasing alarm generation signal 301 is created, and input in a right side biasing alarm device 20R and a suspension EUC5. The right side biasing alarm device 20R generates the alarm by the input of the alarm generation signal 301, and the suspension ECU5 allows a right side suspension body part 3 to generate a contraction-hard damping force, and the left side suspension body part 3 to generate an expansion-hard damping force. Therefore, even if a driver responds to the generation of the alarm excessively and turns the steering wheel to the left to a great extent more than necessary, the automobile 2 can maintain favorable travelling condition.
