A modular electronic damping control system is described and includes a damping component located at a vehicle suspension location. The modular electronic damping control system also includes a control system configured to control the damping component, and determine the type of damping component present. Also, the control system is configured to automatically tune a vehicle's suspension based on the type of damping component present, and automatically monitor the damping component and determine when a change has been made to the damping component so that the control system can then automatically re-tune the vehicle's suspension based on the change to the damping component.

Techniques for using ball joint sensor data to determine conditions relevant to a vehicle are described in this disclosure. For example, in one example, the ball joint sensor data may be used to determine estimated steering data. The estimated steering data may be directly used to navigate through an environment, such as by the vehicle relying on the estimated steering data when planning, tracking, or executing a driving maneuver. Also, the estimated steering data may be used to verify the reliability of other steering sensor data used to navigate through the environment.

A suspension arrangement for a vehicle includes a piston for supporting a flexible bellows assembly of the suspension arrangement, said piston having a first portion connectable to the flexible bellows assembly and a second portion connectable to a wheel axle, said piston further having an outer side and an inner side, and wherein said suspension arrangement further comprises a mounting structure for positioning an insertable sensor device toward the flexible bellows assembly, said mounting structure extending at least from the outer side to the inner side and having an outer opening for receiving the insertable sensor device from an outside of the piston.

Systems, methods, and computer readable storage media provide dynamic chassis and tire status indications associated with a vehicle. Lift axle status data may be graphically represented by a lift axle indicator dynamically provided in a shared notification/messaging space positioned within the driver's line of sight during a lift axle transition. The lift axle indicator may include a side-view representation of the vehicle including a plurality of axle sections indicating the status of each axle. The lift axle indicator may be suppressed when air pressure is stabilized. Additionally, a graphical representation of data associated with statuses (e.g., air pressure, temperature) of each tire may be provided in a top-down view representation of the vehicle including its associated tire/axle configuration and the tire pressure for each tire. The graphical representation may be configured to reflect the correct number of axles and tires per position, and may further include a tractor versus trailer designation.

An active suspension device includes: a preview sensor that detects a height of a road surface in front of a wheel; and an ECU that controls a stroke of a suspension to perform a preview control. The ECU includes: a front wheel preview control part that performs a preview control; a preview control success determination part that determines whether the preview control is successful; and a rear wheel control part that controls a stroke of a suspension of a rear wheel. When the preview control of the front wheel is successful, the rear wheel control part performs a preview control and a skyhook control of a rear wheel to control the stroke of the suspension of the rear wheel. When the preview control of the front wheel is unsuccessful, the rear wheel control part cancels the preview control of the rear wheel and perform the skyhook control of the rear wheel.

A bed truck having multiple axles has a hydraulic suspension including multiple hydraulic cylinders for each axle, a ride height sensor associated with each hydraulic cylinder, a high pressure hydraulic circuit connecting each of the cylinders and accumulators to a hydraulic pressure source, a low pressure hydraulic circuit connecting each of the cylinders to a fluid tank, and a plurality of valves operable to isolate operation of any one hydraulic cylinder from some or all of the other hydraulic cylinders. A control system is operable to control each of the hydraulic cylinders, either independently of all the other hydraulic cylinders, or in concert with one or more other hydraulic cylinders, such control including locking any one or more of the hydraulic cylinders at a minimum ride height position.

A road work machine comprises a frame, a plurality of ground engaging units, a plurality of vertically moveable legs connecting the plurality of ground engaging units to the frame, respectively, a hydraulic system to control heights of the plurality of vertically moveable legs, pressure sensors for sensing hydraulic pressures in the plurality of vertically movable legs, and a controller configured to, in response to signals received from the pressure sensors, generate a control signal. A method for ride control can comprise adjusting an attitude of the machine in response to sensed pressures.

A method for actuating an actuator device of a roll stabilizer for a vehicle. The actuator device has a supply line connection for supplying a supply voltage, a converter for supplying an alternating voltage using the supply voltage, and at least two phase lines for supplying the alternating voltage to actuator connections of an actuator which can be operated using the alternating voltage. The method has a step of reading an interruption signal, which indicates an interruption in the supply of the supply voltage or a deviation from the supply voltage at the supply line connection and a step of providing a protection signal at an interface with a protection device using the interruption signal in order to at least partly prevent a generator voltage which is or can be fed into the phase lines via the actuator connections from being forwarded in response to the protection signal.

A vehicle includes a body including suspension components, multiple wheels coupled to the body, a suspension sensor coupled to one of the suspension components or at least one of said multiple wheels, a camera, a display connected to the camera to display at least part of the camera view, a processor receiving inputs from the suspension sensor, and memory coupled to the processor. The memory includes a program from which an actual horizontal wheel position relative to a path of travel of the vehicle is determined as a function of a vertical position of the at least one of said multiple wheels. And the processor causes an image representative of the actual horizontal wheel position to appear on the display, and wherein vertical is in the direction of gravity and horizontal is perpendicular to the direction of gravity.

Apparatuses and systems for monitoring wheel alignment and/or for controlling vehicle suspension settings to adjust alignment. Described herein are alignment monitoring apparatuses for determining wheel alignment (e.g., camber, castor and/or toe). Also described herein are alignment adjusting or control apparatuses for adjusting one or more of camber, caster and/or toe.
