A suspension monitoring and adjustment system for an off-road vehicle includes a distance sensor arranged to measure shock displacement of a suspension of the vehicle. The system may include an output device configured to output shock displacement data generated by the distance sensor and a processor or programmable circuit operable to produce a visual representation of the shock displacement data output by the output device. The system may include a processor or programmable circuit operable to generate an adjustment signal based on shock displacement data generated by the distance sensor and a suspension adjuster arranged to adjust the suspension of the vehicle in response to the adjustment signal.

A system for monitoring payload of a vehicle includes at least one wireless transmitter comprising a piezo-resistive pressure sensor, a transceiver and a battery unit, encapsulated in an insulating casing, the at least one wireless transmitter being configured to be attached to an axle beam of the vehicle and to emit a wireless signal in response to a mechanical strain of the axle beam, a wireless receiver configured to receive the wireless signal from the at least one wireless transmitter.

This invention pertains to sway bar systems, and a method of controlling their operation. Specifically, the present invention relates to provide a way of adjusting the response characteristics of a sway bar system by changing the structure of the typical sway bar links and regulating the modified structure by utilizing a hydraulic control unit. Said hydraulic control unit independently modifies the fluid path within each said sway bar links by use of one electronically controlled bi-directional valve allowing for closed or opened flow operation, determined by an electronic input being received.

A weight sensing assembly for a semi-trailer truck enabling balancing of a load includes a sensing module, which is one of a plurality thereof. The sensing modules are mountable to wheels of the semi-trailer truck so that each axle has a sensing module engaged to outside wheels thereof. The sensing module obtains a pressure measurement of a tire engaged to the wheel and transmits it to an electronic device. Programming code on the electronic device enables it to utilize a pressure change, upon positioning of a load upon the semi-trailer truck, to determine a weight that is positioned upon an associated axle. The electronic device calculates adjustments to positions of a sliding fifth wheel and of sliding tandems of the semi-trailer truck to obtain positions thereof that will achieve a legal weight distribution of the load. The electronic device presents, upon a screen thereof, the adjustments to a user.

A towable vehicle including a chassis, at least two wheels and a suspension assembly supporting each wheel. The suspension assembly includes a swing arm pivotally mounted to the chassis, an axle mounted proximate an end of the swing arm, the wheel being mounted on the axle, at least one shock absorber extending from the chassis to the swing arm, an airbag swing arm mounting pivotally coupled to the swing arm, an airbag chassis mounting coupled to the chassis, an airbag coupled to the airbag swing arm and airbag chassis mountings so that inflation of the airbag allows a suspension height to be adjusted over an operating range and a pivot arm pivotally mounted to the chassis and the airbag swing arm mounting to maintain an orientation of the airbag swing arm mounting over the operating range.

A sway bar system is described. The sway bar system includes a sway bar having a first end and a second end. An electronically controlled connector to provide a remotely controllable physical connection and disconnection capability between a first location on a vehicle and the first end of the sway bar; and the second end of the sway bar coupled to a second location on the vehicle.

A plug and play suspension system is disclosed. The plug and play suspension system includes at least one electronically adjustable shock assembly, a controller, and a communications network to communicatively couple said controller with said at least one electronically adjustable shock assembly.

A multi-mode air shock is disclosed herein. The air shock includes an air spring having a primary air chamber, and a damper having an insertion end to telescope within the primary air chamber and a coupler to couple with a portion of a vehicle. An adjuster housing is fixedly coupled to an end of the air spring opposite of the damper, the adjuster housing having a secondary air chamber in communication with the primary air chamber and a mounting structure to couple with a different portion of the vehicle. There is a bulkhead with a valve to open or close the fluid communication between the primary air chamber and the secondary air chamber. The air shock also includes a tertiary air chamber in fluid communication with the secondary air chamber but not in fluid communication with the primary air chamber except via the secondary air chamber.

A mobile device intermediary for vehicle adaptation is disclosed. A mobile device intermediary can access driver profile information and vehicle profile information from a remotely located device, determine vehicle adaptation information based on the driver profile information and vehicle profile information, and facilitate access to the vehicle adaptation information to facilitate adapting an aspect of a first vehicle. The mobile device intermediary can further receive other vehicle profile information related to a second vehicle associated with a driver profile and include the other vehicle profile information in determining the vehicle adaptation information. The vehicle adaptation information can be related to adapting a performance aspect of the first vehicle. The vehicle adaptation information can also be related to adapting an amenity aspect of the first vehicle. Vehicle adaption information can provide improved safety and driver comfort as a driver uses different vehicles, can be portable, and can be device independent.

A hydraulic suspension system controller is disclosed, comprising a controller in operable communication with a hydraulic system of a vehicle. The controller includes at least one display, at least one indicator, and a plurality of buttons, wherein each button corresponds to a function of the controller, and wherein each function effects the hydraulic system to raise and lower at least one of a plurality of solenoids each in operable communication with a hydraulic actuator to extend or contract the hydraulic actuator. A fail-safe module is in operable communication with the controller, the fail-safe module receiving a plurality of signals from a sensor array to monitor the hydraulic system.
