Abstract
Embodiments related to systems and methods for controlling the relative amounts of rotation and heave motions applied to a seat by an active seat suspension system are described.
Claims20
A method for controlling motion of a seat in a vehicle, the method comprising:
- applying a first rotation response and a first heave response to the seat with a first control strategy;
- receiving a vehicle condition of the vehicle;
- determining a second control strategy based at least partly on one or more of a driving condition and the vehicle condition;
- and
- applying a second rotation response and a second heave response to the seat with the second control strategy;
- wherein the first control strategy has a first maximum threshold for at least one of heave and rotation, and wherein the second control strategy has a second maximum threshold for the at least one of heave and rotation wherein the first maximum threshold is different from the second maximum threshold.
3 more elements
A vehicle active seat suspension system comprising:
- at least two actuators configured to be attached to the vehicle seat to control rotation of the vehicle seat about at least one axis and heave of the vehicle seat;
- and
- a controller operatively coupled to the at least two actuators, wherein the controller is configured to command the at least two actuators to apply a first rotation response and a first heave response to the seat with a first control strategy, wherein the controller is configured to receive vehicle condition about the vehicle, wherein the controller is configured to determine a second control strategy based at least partly on one or more of a determined driving condition and the vehicle condition, and wherein the controller is configured to command the at least two actuators to apply a second rotation response and a second heave response to the seat with the second control strategy;
- wherein the first control strategy has a first maximum threshold for at least one of heave and rotation, and wherein the second control strategy has a second maximum threshold for the at least one of heave and rotation, wherein the first maximum threshold is different from the second maximum threshold.
