Controlling active isolation platform in a moving vehicle
First Claim
1. A seat system for a vehicle, the system comprising:
- a seat;
a support structure coupled to the seat that allows the seat to move about a first 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 in part on the first signal and the second signal to instruct the actuator to position the seat at a desired command angle, wherein the controller is configured to reduce the second sensor signal by accelerations caused by steering the vehicle to correct the command signal; and
provide a force command to the actuator to move the seat at the desired command angle based on at least the corrected command signal.

Abstract
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.

11. A method of controlling seat movement in a vehicle, the method comprising:
-
receiving a first signal from a first sensor positioned to detect movement of the vehicle; receiving a second signal from a second sensor positioned to detect lateral acceleration of a pivot including a first axis about which a support structure coupled to a seat allows movement of the seat; generating a command signal based at least in part on the first signal and the second signal to instruct an actuator to position the seat at a desired command angle, wherein generating the command signal includes reducing the second sensor signal by lateral accelerations caused by steering the vehicle to correct the command signal; and providing a force command to the actuator to move the seat at the desired command angle based on at least the corrected command signal. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A vehicle seat comprising:
-
a seat configured to move at a command angle about a first axis of a pivot relative to a substantially horizontal orientation; and a controller configured to; receive a first signal of detected movement of a vehicle and a second signal of detected lateral acceleration of the pivot; and generate a command signal based on at least the first signal and the second signal to instruct an actuator to position the seat at a desired command angle, wherein the controller is configured to reduce the second signal by lateral accelerations caused by steering the vehicle to correct the command signal. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
