Embodiment Construction

[0049] An actively suspended device includes a seat, or other platform, connected to one or more active suspension elements, each active suspension element providing active suspension along an axis. In many cases it is useful, but not required, to use passive elements cooperating with active suspension elements along one or more axes. In this case, the active suspension elements can be installed in series or in parallel with the passive suspension elements.

[0050] In the following description, numerous references will be made to the position and movement of devices. It will be appreciated that for ease of discussion in the disclosed embodiments, "position" refers to the position of the device relative to the vehicle, and "movement" refers to the movement of the device relative to an inertial reference frame. Reference to a location signal thus refers to a signal that has information about the location of the device relative to the vehicle. Reference to a movement signal me...

Abstract

The invention relates to a method of actively suspending an actual device in a vehicle, the method comprising modifying a control signal based on the difference between the properties of the actual device and the properties of the nominal device, the actual device properties being determined by the actual device to the control signal Response is indicated.

Description

technical field [0001] The present invention relates to active suspension. Background technique [0002] A vehicle moving in the desired direction will inevitably be affected by movement in other directions. This undesired movement often results from disturbances in the medium in which the vehicle is traveling. For example, whether traveling by car, ship or plane, people may encounter bumps, waves and bubbles. [0003] At best, this occasional acceleration can lead to discomfort and annoyance for passengers. For some impressionable individuals, these occasional accelerations can cause dizziness and nausea. In some cases, however, particularly hard acceleration can cause the operator to briefly lose control of the vehicle. [0004] Even when the vehicle is stationary, there is some residual vibration associated with the vehicle's engine. During movement, even on smooth roads, this residual vibration can be oppressive and tiring. Contents of the invention [0005] In g...
