US Patent 10882424 Controlling active isolation platform in a moving vehicle

Systems and methods for actively isolating a payload from a disturbance. In one example, a seat system for a vehicle includes a seat, a support structure that allows the seat to move about an axis of a pivot, a first sensor positioned to detect movement of the vehicle, a second sensor positioned to detect lateral acceleration of the pivot, an actuator configured to move the seat, and a controller configured to receive a first signal from the first sensor and a second signal from the second sensor, generate a command signal based at least on the first and the second signal to instruct the actuator to position the seat at a desired command angle, wherein the controller is configured to correct the command signal for lateral accelerations caused by steering the vehicle, and provide a force command to the actuator to move the seat at the desired command angle.
