Lean-in cornering platform for a moving vehicle
First Claim
1. A method of controlling the movement of a seat coupled to a vehicle, the method comprising:
- receiving a first input from at least a first sensor positioned to measure movement of the vehicle, wherein the first input includes a vehicle roll rate;
receiving a second input from at least a second sensor positioned to measure movement of the vehicle, wherein the second input includes a total lateral acceleration of the vehicle in a direction substantially perpendicular to an axis extending parallel to a direction of travel of the vehicle around a turn;
determining a distance between a first axis of a pivot about which the seat is configured to rotate, and a second axis about which the vehicle may rotate;
determining a cornering lateral acceleration of the vehicle in the direction substantially perpendicular to the axis extending parallel to the direction of travel of the vehicle around the turn, the cornering lateral acceleration being determined based at least in part on the total lateral acceleration, the vehicle roll rate, and the distance between the first axis and the second axis;
generating a command signal based at least in part on the cornering lateral acceleration of the vehicle to instruct an actuator coupled to the seat to rotate the seat about the first axis of the pivot in substantially a direction of the turn; and
providing a force command to the actuator to move the seat based on the command signal.

Abstract
Systems and methods for improving ride quality of an active payload support system. In one example, a seat system for a vehicle includes a seat, a support structure including an actuator configured to rotate the seat about an axis of a pivot, a first sensor positioned to detect movement of the vehicle, and a controller configured to receive a first input from the first sensor, determine a cornering lateral acceleration of the vehicle in a direction perpendicular to an axis parallel to a direction of travel of the vehicle around a turn, the cornering lateral acceleration determined based at least on the first input, generate a command signal based at least on the cornering lateral acceleration to instruct an actuator to rotate the seat about the axis of the pivot in a direction of the turn, and provide a force command to the actuator to move the seat.
