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.

Methods and systems for autonomously delivering consumer items in disposable packages, in which the disposable package, with the consumer item inside, are carried under a wheel robot using a grabbing mechanism that holds the package under the wheel robot. The wheel robot straddles over the package to allow the grabbing mechanism access to the package during a loading process, and then straddles off the package at a delivery location after the grabbing mechanism releases the package with the consumer item inside. Releasing of the package can be done by lowering the package to the ground in a controlled manner, or by simply releasing the package above ground thereby dropping the package.

The present disclosure relates to a mobility device having an active suspension function and method therefor. The mobility device may include: a suspension module located between a wheel and a sash of the mobility device and configured to perform a suspension function to the mobility device; a sensor module comprising an inclinometer and a ride height sensor; and a communication module configured to support vehicle-to-everything (V2X) communication. The communication module may be configured to provide, as first suspension module control information for a subsequent mobility device, road surface information obtained by the inclinometer and the ride height sensor during driving of the mobility device based on the V2X communication.

A shock absorber includes a gas spring cylinder containing a piston moveable between an extended position and a compressed position within the gas spring cylinder. A mechanical actuator is arranged whereby a bleed port is automatically closed when the gas spring is compressed to a predetermined position corresponding to a desired sag setting. In one embodiment, the position corresponds to a predetermined sag setting whereby the gas spring is partially compressed. In another embodiment, a proper sag setting is determined through the use of a processor and sensor that in one instance measure a position of shock absorber components to dictate a proper sag setting and in another instance calculate a pressure corresponding to a preferred sag setting.

A suspension system and associated control methods for improving comfort by disabling passive pitch stiffness in the suspension system by holding open electromechanical comfort valves positioned in a manifold assembly of the suspension system. The manifold comfort valves are held open to disable the passive pitch stiffness of the suspension system if the vehicle is traveling down a rough road or if the vehicle is approaching a discrete road event like a pot-hole or speed bump. Deactivation of the passive pitch stiffness of the suspension system is determined based on road classification information, saved road events, and/or real-time vehicle data from on-board sensors. The suspension system therefore reduces pitch angles during pitch events induced by inertial forces caused by driver inputs and disables the pitch stiffness when the pitch event is caused by road inputs.

Provided is an electric suspension device including an electromagnetic actuator that is provided between a body and wheel of a vehicle and generates a load for damping vibration of the body. It includes: a camera that detects preview image information of a road surface in front of the vehicle; a 3D gyro sensor that detects a sprung speed of the vehicle; a target load computation unit that computes a target load based on the preview image information and the sprung speed; and a load control unit that controls the load of the actuator by using the computed target load. When a detection result based on the preview image information indicates that the front road surface is even but a detection result based on the sprung speed indicates that the front road surface is uneven, the target load computation unit computes the target load based on the sprung speed.

The vehicle control device of the present invention acquires characteristics of a road condition in front of a traveling vehicle based on external information; acquires vehicle behavior control variables for controlling the behavior of the vehicle based on estimated state variables of the vehicle that are obtained based on the characteristics, and control variables concerning speed of the vehicle based on the external information; acquires trajectory tracking control variables for causing the vehicle to track the target trajectory based on the target trajectory on which the vehicle travels that are obtained based on the characteristics and the estimated state variables; and outputs the control commands for controlling the suspension device, steering device, and braking and driving device based on the vehicle behavior control variables and the trajectory tracking control variables. This improves travel stability of the vehicle on a road surface on which an irregularity such as ruts exists.

Motion can be induced at a vehicle, e.g., by actuating components of an active suspension system, and first sensor data and second sensor data representing an environment of the vehicle can be captured at a first position and a second position, respectively, resulting from the induced motion. A second sensor can determine motion information associated with the first position and the second position. Calibration information about the sensor, the first sensor data, and the motion information can be used to determine an expectation of sensor data at the second position. A calibration error can be the difference between the second sensor data and the expected sensor data.
