摘要： PROBLEM TO BE SOLVED: To establish a great effect of vibration control by eliminating a time lag in control as much as possible. SOLUTION: Part of an engine 3 is supported by a side beam 1 of a car body through a vibration reducing device 2, and a body vertical acceleration sensor 8, engine vertical acceleration sensor 9, and wheel vertical acceleration sensor 10 are mounted on a body panel 4, the engine 3, and a strut 5, respectively. First a check is made for the amount of moving condition of each wheel 6 having the greatest influence as a vibration source, and if the obtained value is large, a high damping force is generated instantly, and the influence upon vibrations by the engine 3 is judged through comparison with the car body using the vertical direction absolute velocity as the amount of moving condition, and the damping force of the vibration reducing device 2 is set to a favorable value for vibration control. The processing time in the control flow is much shorter than the transmitting time till the start of vibrating from when the force due to the motion of a car body mounting member is transmitted to the car body, and the control can be made before the car body receives influence of the vibration.

摘要： PROBLEM TO BE SOLVED: To improve comfortableness by processing the measured value of the suspended vibration wave-form of a damper device normally set to a high damping characteristic with a band-pass filter, and switching the damper device to a low damping characteristic when the passing signal value is larger than the prescribed threshold value. SOLUTION: Suspended acceleration is read by an acceleration sensor for the measurement of the suspended vibration wave-form signal value of a damper device (ST1), the measured value is processed by a band-pass filter set with the passing frequency band to the region between the suspended and nonsuspended resonance frequencies (ST2), then the processed signal value S is compared with a preset threshold value TH (ST3). The threshold value TH is set to such a value that whether the input deteriorates comfortableness or not can be judged. When the signal value S is judged to be larger than the threshold value TH, a low damping characteristic is set (ST4). When the signal value S is judged to be smaller, a high damping characteristic is set (ST5). A step motor is controlled by the switching signal to rotate it.

摘要： PROBLEM TO BE SOLVED: To enlarge a variable width of samping force as well as improving trend of lowering the damping force by arranging a damper extension exclusive flow passage and contraction exclusive flow passage on a valve element for adjusting the grade of communication by penetrating in radial direction and arranging serially in shaft direction. SOLUTION: During a period of samper extension, since a piston member 3 is displaced upward, oil flows in a damping force upper limit setting flow passage 13a and a damping force erection setting flow passage 13d firm a damper extension exclusive flow passage 13 in the direction from an oil chamber 2b toward and oil chamber 2a. The oil having flowed in the flow passage 13b passes a radial through hole 18a via the opening window 10b of a valve element 18 flows in a flow passage 13d so as to push and open a sub-valve 19 and flows out to the oil chamber 2a. The sub-valve 19 is so arranged to open a main valve 15 at the upper limit valiue of the damping force. These components come to have the lowest damping force characteristic when the through hole 18a is under fully opened state owing to the turning motion of valve element 18 and to be the highest damping force characteristics under fully closed state. This valve element 18 is variably adjustable and can be automatically set properly in compliance with running conditions.

摘要： PROBLEM TO BE SOLVED: To prevent a step motor and a drive circuit from heating and increasing the load by holding a valve body on a damping characteristic set position by a holding mode in which a driving quantity is smaller than that at a driving mode. SOLUTION: It is judged whether a step motor is driven or not (ST1), for example, the case of changing from low damping characteristic to high damping characteristic is set to be normal rotation, then in the reverse case it is reverse rotation, the normal or reverse rotation is discriminated (ST2), and in order to rotationally move a valve body to an optional damping characteristic set position (a prescribed set angle), control to supply driving voltage required for driving the step motor is carried out (ST3), thereafter control to output holding voltage for holding it (ST4) is carried out. The holding voltage is lower than the driving voltage at a driving mode, and it is concretely a voltage value of the degree necessary for holding the step motor on the present position against torque variation such as pressure change of fluid acting on the valve body.

摘要： PURPOSE: To obtain a method for estimating the speed at which hydroplaning phenomenon is generated and a method for detecting the generation area thereof. CONSTITUTION: A road noise detected through an amplifier and a filter is subjected to frequency analysis and sound pressure normalization while a vehicle speed detected through a vehicle speed detection means is normalized at a vehicle speed normalizing section. The normalized vehicle speed and road noise are inputted to each cell in the input layer of a neural network 13. The neural network 13 detects the conditions of a pavement, especially the quantity of water on a wet pavement, and a hydroplaning phenomenon detecting section 14 retrieves a map stored in a memory 15. Control signals are outputted to an alarm and a motion controller depending on the value being read out.
