Vehicle seat with angle trajectory planning during large events
First Claim
1. A method of controlling movement of a seat in a vehicle relative to the vehicle, comprising:
- receiving a signal from at least one sensor positioned to detect movement of the vehicle;
based at least on the received signal, determining a desired displacement value of the seat relative to the vehicle;
determining whether the desired displacement value exceeds a threshold value;
in response to determining that the desired displacement value exceeds the threshold value, scaling the desired displacement value to calculate a scaled displacement value that is less than the desired displacement value; and
operating an actuator to displace the seat to the scaled displacement value.

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.

8. A seat system of a vehicle, comprising:
-
a seat positioned at a first position relative to the vehicle; an actuator arranged to move the seat relative to the vehicle; a sensor configured to sense motion of the vehicle; and a controller configured to; receive a signal from the sensor, wherein the signal corresponds to a movement of the vehicle; in response to the received signal, generate a signal to command the actuator to move the seat to a second position relative to the vehicle; determine whether the second position exceeds a limit; and upon determining that the second position exceeds a limit, scale the command signal. - View Dependent Claims (18, 19, 23, 24, 25)

12. A seat system for a vehicle, comprising:
-
a seat configured to rotate relative to the vehicle; an actuator configured to rotate the seat; 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, based on the received signal, determine a desired angle of rotation of the seat, determine whether the desired angle exceeds a threshold angle, in response at least to determining that the desired angle exceeds the threshold angle, scale the desired angle of rotation to determine a scaled angle of rotation; calculate a value of a force at least partially based on the scaled angle of rotation; and command the actuator to apply the force to the seat. - View Dependent Claims (13, 14, 15, 16, 17, 20, 21, 22)
