VEHICLE SEAT WITH ANGLE TRAJECTORY PLANNING DURING LARGE EVENTS
First Claim
1. A method of controlling seat movement in a vehicle, comprising:
- receiving a signal from at least one sensor positioned to detect movement of the vehicle;
generating a command signal to instruct an actuator coupled to the seat to move the seat relative to a vehicle centerline;
determining whether the command signal will cause the seat to exceed a limit;
scaling the command signal to conform movement of the seat to movement of the floor of the vehicle within the limit; and
providing a force command to the actuator to move the seat based on the scaled command signal.

Abstract
Systems and methods for controlling movement of an active payload support system. In one example, a seat system for a vehicle includes a seat, a support structure coupled to the seat and including an actuator configured to move the seat at a command angle relative to a floor of the vehicle responsive to movement of the vehicle, at least one sensor positioned to detect movement of the vehicle, and a controller configured to receive a signal from the at least one sensor, generate a command signal to instruct the actuator to move the seat relative to a floor of the vehicle, determine whether the command signal will cause the seat to exceed a limit, scale the command signal to conform to movement of the vehicle within the limit, and provide a force command to the actuator to move the seat based on the scaled command signal.
