An end member assembly can include a first end member section and a second end member section that together form an end member volume. A partition section is provided separately and is disposed within the end member volume to separate the end member volume into at least two volume portions. At least one passage extends through the partition section and at least one control device is disposed in fluid communication along the passage. The control device substantially fluidically isolates the two volume portions under conditions of use below a predetermined differential pressure threshold. The control device permits fluid communication between the two volume portions under conditions of use in which the predetermined pressure threshold is exceeded. Gas spring assemblies including such an end member assembly as well as suspension systems and methods of manufacture are also included.

An electro-dynamically controlled leveling system having a plurality of air springs mounted on at least one axle of a vehicle for supporting the weight of the vehicle; one or more electro-pneumatic valves; and one or more sensors that monitor one or more characteristics of the vehicle and transmit the one or more characteristics as a sensory input. The electro-dynamically controlled leveling system includes a central control module in electrical communication with the one or more sensors and the one or more electro-pneumatic valves. The central control module receives the sensory input from the one or more sensors, calculates a dynamic condition of the vehicle based on the sensory input, determines a desired air pressure for each air spring based on the calculated dynamic conditions of the vehicle, and transmit a command to the electro-pneumatic valves to adjust the air pressure of the air springs.

A wheel with an intelligent suspension system that includes a hub, a rim and a set of spokes with dynamically adjustable spoke lengths. Further included is one or more sensors associated with at least the hub and the rim and a microcontroller unit (MCU) that receives sensory signals from the one or more sensors, and transmits control signals to the set of spokes to dynamically control spoke lengths of the set of spokes.

In a suspension controlling apparatus for a vehicle including a suspension whose damping force is variably settable and a control unit capable of controlling the damping force of the suspension, for appropriately obtaining a pitch behavior. When a vibration state of a vehicle in a vertical direction exceeds a given vibration state, a control unit controls damping force of suspensions on the basis of a target damping force in order to execute a skyhook control. However, when acceleration in a forward and rearward direction of the vehicle is outside a given range, a decision condition for the given vibration state is changed to a condition on the side on which the skyhook controlling damping force control of the suspensions is less likely to be started.

In a suspension controlling apparatus for a vehicle which includes a suspension whose damping force is variably settable and a control unit capable of executing skyhook control on the basis of target damping force for skyhook control to control the damping force of the suspension, the vehicle stability is raised upon skyhook control during turning of the vehicle. Target damping force limit value determination device provided in a control unit determines target damping force limit values for skyhook control such that a value obtained by subtracting, from the target damping force limit value on the decompression side when the suspension is in a decompressed state, the target damping force limit value on the compression side when the suspension is in a compressed state increases as a roll angle detected by a roll angle sensor increases. The control unit limits the target damping forces with the target damping force limit value.

A vehicle height adjustment apparatus includes a control device. The control device controls the opening degree of the solenoid valve to allow a movement amount of the support member to reach a movement amount target value that corresponds to the vehicle height set in advance, in accordance with the weight applied to the vehicle. The control device controls the opening degree of the solenoid valve to change the movement amount of the support member based on a difference between a value based on the information related to the vehicle height and a vehicle height-related target value, on condition that the movement amount of the support member reaches the movement amount target value and the value based on the information related to the vehicle height obtained by the information obtaining device does not reach the vehicle height-related target value that corresponds to the vehicle height set in advance.

Various embodiments of the present disclosure provide a ride height sensing system that includes an encoded electromagnetic source as an input unit for a Hall Effect sensors and the signal from the electromagnet is encoded to enable the rejection of ambient magnetic field. In various embodiments of the present disclosure, a band pass filter is used for signal processing of the encoded electromagnetic data. Additionally, several Hall Effect sensors may be used with a single electromagnetic source to provide multi-axis sensing and as such, provides robustness in determining ride height changes, or in the case of dependent suspensions (solid axle), a single electromagnetic source can used to determine ride height at multiple locations on the axle.
