摘要： 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.

摘要： 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.

摘要： An active vibration isolation system for a motor vehicle seat that is adapted to be occupied by a user, includes an active suspension system that supports the seat above a floor of the motor vehicle, where the suspension system comprises at least one actuator that can be controlled to move the seat up and down in the direction of a vertical axis, a first sensor system mounted to the vehicle and that is adapted to sense vehicle height position changes along or parallel to the vertical axis, a second sensor system that is adapted to determine the seat translational position along or parallel to the vertical axis, and a controller that, in response to the first and second sensor systems, is adapted to provide control signals to the active suspension system that cause motions of the seat that are designed to control the height of the user's head or torso as the vehicle undergoes translations along the vertical axis.

摘要： The present disclosure discusses an active seating system that includes a load leveling mechanism. The load leveling mechanism includes a force bias actuator assembly,a roll actuator assembly, a heave actuator assembly, a first torsion rod connected to the force bias actuator and the roll actuator, and a second torsion rod connected to the force bias actuator and the heave actuator. Each of the force bias actuator assembly, roll actuator assembly, and heave actuator assemblies comprises a housing, a DC motor disposed within the housing, and a ball screw with a driveshaft, the driveshaft of the ball screw being coaxial with a rotor of the DC motor. The active seating system also includes a seat top and an interface configured to mount the seat top to the load leveling mechanism.

摘要： Embodiments related to active vibration isolation systems for a vehicle seat, as well as their methods of use, are disclosed. In some embodiments, an active suspension system may be configured to support a seat above a floor of a vehicle. The active suspension system may include two or more actuators that may be operated cooperatively to control both the roll and heave of the vehicle seat. In some instances, these actuators may also be non-back-drivable actuators. Additionally, in some embodiments, an active suspension system may include one or more torsion springs that apply torques in parallel with associated actuators of the active suspension system to support at least a portion of the loads applied to the active suspension system during operation.

摘要： An actuator (100) includes a first rotary motor (102), a second rotary motor (104), and a transmission coupled to the first and second rotary motors. The transmission converts rotation of the first rotary motor (102) in a first direction and simultaneous rotation of the second rotary motor (104) in a second direction to linear motion of an output shaft (120) in a single direction. The actuator is usable in an active automobile suspension.

摘要： A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. One or more sensors can each measure an aspect of motion. A processor can (i) receive input from each of the one or more sensors, (ii) determine from this input a measure of rotation of the vehicle away from a nominal, level horizontal orientation, and (iii) utilize the input to determine a desired rotation of the seat. An angle that the seat has been rotated away from a nominal, level orientation is more than insubstantially larger than an angle that the vehicle has rotated away from a nominal, level horizontal orientation.

摘要： A seat system for a vehicle includes a seat having a seat bottom on which a person can sit. An intermediate support structure is secured to the seat and the vehicle which allows the seat to rotate relative to the vehicle. An actuator can interact with the seat to cause the seat to rotate relative to the vehicle. The combined motion of the vehicle relative to the earth and the seat relative to the vehicle results in motion of the seat moving about a virtual pivot point. A user control is provided for adjustment of the location of the virtual pivot point.
