Abstract
Embodiments related to the operation of an active seat suspension using prefiltered road data are described. In one embodiment, the prefiltered road data may be filtered to exclude road and/or driving inputs with low frequencies, or long length scales, such as hills or curves. Such an embodiment may at least partially reduce operation of an active seat suspension in response to these low frequency long length scale of inputs where displacements of the vehicle may be greater than a range of motion of the active seat suspension while still permitting the active seat suspension to respond to higher frequency inputs.
