In one embodiment, one or more suspension systems of a vehicle may be used to mitigate motion sickness by limiting motion in one or more frequency ranges. In another embodiment, an active suspension may be integrated with an autonomous vehicle architecture. In yet another embodiment, the active suspension system of a vehicle may be used to induce motion in a vehicle. The vehicle may be used as a testbed for technical investigations and/or as a platform to enhance the enjoyment of video and/or audio by vehicle occupants. In some embodiments, the active suspensions system may be used to perform gestures as a means of communication with persons inside or outside the vehicle. In some embodiments, the active suspensions system may be used to generate haptic warnings to a vehicle operator or other persons in response to certain road situations.

A controller estimates a state of a vehicle based on a wheel speed sensor provided on the vehicle, and outputs a control signal to a shock absorber provided between a wheel and a vehicle body according to the estimated state of the vehicle. The controller uses information of a sensor of an in-vehicle apparatus other than an apparatus dedicated to the shock absorber as an observed value in the estimation of the state of the vehicle. In other words, the controller uses sensor information of a navigation apparatus corresponding to the in-vehicle apparatus other than the shock absorber, more specifically, gyro information meaning information of a gyro sensor mounted on the navigation apparatus as the observed value in the estimation of the state of the vehicle.

A computer-implemented method for controls stability of a vehicle, being a truck or tractor and at least one trailer comprising at least two wheel axles and an electronically controllable suspension system. The method identifies a possible instability state of the vehicle; determines a type of an event that has caused the possible instability state; determining one or more actions comprising adjusting a load distribution between the at least two wheel axles of the trailer based on the possible instability state and based on the type of the event that has caused the possible instability state; and generates and sending a control command to the suspension system to perform the actions. The actions may comprise adjusting the load distribution between the at least two wheel axles of the trailer such that a load on a rear axle is increased and a load on a front axle is decreased.

A robot and a robot control method are provided. The robot includes: a robot body, a pose detector being mounted on the robot body; a chassis body provided at a bottom of the robot body; a moving assembly connected to the robot body through a suspension shock absorber, the moving assembly being further connected to a controllable damping rotating shaft, and rotationally connected to the chassis body through the controllable damping rotating shaft; and a controller electrically connected to the pose detector and the controllable damping rotating shaft, respectively, and used to control the controllable damping rotating shaft to change rotational resistance according to pose information of the robot detected by the pose detector.

A method for regulating an air suspension system of a stationary motor vehicle, includes comparing a predetermined target level position with an actual level position of the vehicle; determining an actual air quantity in at least a number of air springs of the air suspension system and comparing the actual air quantity with a reference air quantity. If the actual level position falls below the target level position and the determined air quantity falls below the reference air quantity, the air springs of the air suspension system are then filled while the actual level position is monitored. If the actual level position continues to be below the target level position or the actual level position does not change, the filling of the air springs is carried out only until the reference air quantity corresponding to the target level position is reached as the actual air quantity in the air springs.
