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, 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.

Abstract: Embodiments related to active seat suspensions as well as their methods of operation are disclosed. In one particular embodiment, a failure state of an active seat suspension may be detected after which operation of one or more actuators of the active seat suspension may be limited in response to the detected failure state. In another embodiment, a crash or imminent crash of a vehicle may be detected and an active seat suspension may be operated to lower a seat connected thereto to lower the seat toward an underlying portion of the vehicle. In yet another embodiment, operation of an active seat suspension may be limited to reduce a temperature of the active seat suspension when a rate of change and/or a magnitude of a sensed temperature of an actuator of an active seat suspension is greater than a predetermined threshold.

Abstract: Embodiments related to systems and methods for controlling an active vehicle seat are described. In some embodiments, the active vehicle seat is controlled based at least partly on internal sensor information, external sensor information, and operator input from a user interface.
