摘要： In a system for controlling active suspensions of a motor vehicle, having fluid suspensions for the respective wheels, a longitudinal acceleration sensor, a lateral acceleration sensor, control valves for the respective suspensions, and a controller for producing a control quantity to adjust the control valves to charge and discharge fluid into and out of the fluid suspensions so as to control the vehicle attitude, the reaction force of each suspension is detected and a mean value of the suspension reaction force is calculated to determine the loading condition of the vehicle while the vehicle is driven straight ahead at a constant speed. The control quantity is corrected by a correcting circuit so as to match the loading condition of the vehicle whereby the vehicle attitude is precisely controlled so as to match the vehicle weight even in such a transient state as acceleration, deceleration and turning. The internal pressure of each suspension may be detected as the reaction force.

摘要： An active suspension system of an automotive vehicle having four air suspension units for four wheels has a first sensor for detecting vertical acceleration of the mass above each suspension unit spring, a second sensor for detecting the vertical relative displacement of the masses above and below each unit spring, a controller for operating in response to the output signals from the two sensors and a relative displacement velocity signal obtained by differentiation of the signal from the second sensor to generate an instruction air flow quantity signal, and a control valve operating in response to this flow quantity signal from each controller to control the charging or discharging of air into or from each unit. An auxiliary damper is provided in each unit to damp vibrations of relatively high frequencies. A low-pass filter is used to filter off a relatively high-frequency component of the output signal of at least the first sensor, whereby vibrations of relatively low frequencies are damped and absorbed by the operation of the air spring action of each unit according to the operation of the control valve.

摘要： An active fluid suspension system has a controller for controlling the delivery and withdrawal of air to and from individual suspension units at vehicle wheels in response to the sensor output signals representing a prescribed set of vehicle behaviors. The controller includes insensitivity zone filters each for filtering out those portions of one sensor output signal of which amplitudes are within an insensitivity zone, thereby avoiding unnecessary fluid flow into and out of the suspension units. The insensitivity zone is defined as a range of amplitudes between given positive and negative values. The filters widen the insensitivity zones with an increase in vehicle speed for optimum suspension control in all vehicle speed ranges.

摘要： In a motor vehicle having a vehicle height adjusting device, wherein the height of each suspension is controlled so as to attain a set reference vehicle height, reaction forces of respective suspensions are detected and a difference between the detected reaction forces is calculated according to a formula, while the vehicle is stationary or is being driven straight. When the difference exceeds a predetermined value, it is determined that there are imbalances of the road surface contact loads of the wheels. Upon the determination of imbalances, the reference vehicle height is increased for some suspensions and decreased for other suspensions to eliminate the imbalances. The determination of imbalances is made when a value given by a formula including the integrated values for the suspensions exceeds a predetermined value, and then reference vehicle height is increased and decreased for the suspensions to eliminate the imbalances.

摘要： An apparatus for adjusting height of a vehicle includes an incremental-type rotary encoder operated as a sensor for sensing the height of the vehicle. The incremental-type rotary encoder comprises a rotary disc having two sets of slits positioned at circumferential portions having different radii each other and different phase of 90.degree. in a rotating direction of the rotary disc. The incremental-type rotary encoder is further provided with a slit having a semi-circular shape disposed along a circumferential periphery thereof. A neutral position of an operation range of the rotary disc is determined as a boundary of the location of the semi-circular slit. The semi-circular slit is detected to discriminate whether height of the vehicle is above or below the neutral position of the rotary disc. A height adjusting mechanism is displaced in a vertical direction according to data from a detector. The apparatus controls the rotating direction and the amount of the rotation of the rotary disc.

摘要： In a system for controlling active suspensions of a motor vehicle, having fluid suspensions for the respective wheels, a lateral acceleration sensor, control valves for the respective suspensions, and a controller for adjusting the control valves to charge and discharge a fluid into and out of the fluid suspensions so as to control the vehicle attitude, a shut-off valve is provided between each control valve and each fluid suspension. The shut-off valve is normally open to enable the control of the vehicle attitude in an active state. When the detected lateral acceleration of the vehicle during a turn exceeds a set reference lateral acceleration, an active-passive changeover circuit delivers a shut-off signal to each shut-off valve thereby to close the shut-off valve, whereby all the fluid suspensions are sealed so that the suspension system becomes a passive state. This enables the elimination of the excessive peformance of the active suspension system and makes the suspension units smaller and less costly, reducing energy consumption.
