A method and system for adjusting the height of a vehicle's air suspension through a software application or physical buttons or dials is provided. The system includes a ride height sensor that is configured to detect and measure the height of a vehicle. Further, the system includes an electronic module in communication with the ride height sensor and a ride height control module of the vehicle, wherein the ride height sensor or the electronic module being adapted to alter voltage/current or encoder data sent to the ride height control module. Further, the system includes means for electronically programming the ride height sensor or the electronic module, wherein the programming is performed using physical buttons or dials on the sensor or by connecting the electronic module to a user's electronic device via Bluetooth or other wireless or wired technology.

A suspension control apparatus and a suspension control method are provided that can appropriately suppress road surface vibration transmitted to a vehicle body during traveling, and can reduce power consumption by estimating the road surface shape in front of a vehicle, and changing driving of an active suspension and a damper based on this information.

A suspension control apparatus that controls a suspension device to be attached to wheels of a movable body, the suspension device consisting of an active suspension capable of adjusting a vehicle height, and a damper capable of adjusting a damping force, the suspension control apparatus including a road surface shape measurement device that obtains a road surface shape, an actuator control device that controls driving of the suspension device, and an actuator drive selection device that changes driving of the suspension device based on information obtained by the road surface shape measurement device.

An unmanned ground-based hygiene maintenance vehicle, UGV, includes a housing with a base plate, top plate and housing side wall substantially perpendicular to the base plate. Arranged in the housing is at least one wheel drive coupled to at least one wheel in a recess in the base plate. The UGV includes sensors for sensing the environment of the UGV, and a controller for autonomous location and navigation of the UGV based on sensing parameters of the sensors. The UGV includes an articulated robot arm on the top plate of the housing and to support a hygiene maintenance tool. The UGV includes at least one load-receiving element coupled to the housing side wall and extending outwards from the housing side wall, wherein the load-receiving element includes a load support surface for supporting a hygiene maintenance tool supply module with respect to a vertical direction extending transverse to the base plate.

A multi-degree-of-freedom active damping mechanism control method, system and a damping mechanism are provided. A skyhook active damping control algorithm is used for controlling an electric cylinder output force in a vertical damping direction, and an adaptive control algorithm with an adaptive rate is used for correcting a load moment of inertia in pitch and roll damping directions. At the same time, a predictive model is established according to a task space linearization equation near an equilibrium point, and states of the system at N future moments are predicted in advance at each moment to achieve optimal control under complex constraints and reduce the influence of system delay. At the same time, the three control methods may further improve the active damping effect of the damping device by combining road information obtained by a visual sensor in real time.
