Methods and systems for controlling vehicle body motion and occupant experience
First Claim
1. A method of reducing road induced motion within a vehicle, the method comprising:
- controlling a first active suspension system associated with a first portion of the vehicle in at least a first range of frequencies to reduce a motion of the first portion of the vehicle;
controlling a second active suspension system operatively interposed between the first portion of the vehicle and a second portion of the vehicle in at least a second range of frequencies different from the first range of frequencies to reduce a motion of the second portion of the vehicle.

Abstract
In one embodiment, one or more suspension systems of a vehicle may be used to mitigate motion sickness by limiting motion in one or more frequency ranges. In another embodiment, an active suspension may be integrated with an autonomous vehicle architecture. In yet another embodiment, the active suspension system of a vehicle may be used to induce motion in a vehicle. The vehicle may be used as a testbed for technical investigations and/or as a platform to enhance the enjoyment of video and/or audio by vehicle occupants. In some embodiments, the active suspensions system may be used to perform gestures as a means of communication with persons inside or outside the vehicle. In some embodiments, the active suspensions system may be used to generate haptic warnings to a vehicle operator or other persons in response to certain road situations.

9. A vehicle, comprising:
-
a first portion of the vehicle; a second portion of the vehicle; a third portion of the vehicle; at least one actuator of a first active suspension system operatively disposed between the first portion and the second portion; and at least one actuator of a second active suspension system operatively disposed between the second portion and the third portion; wherein a relative motion between the first portion and the second portion is at least partially controlled in a first range of frequencies by the first active suspension system, and wherein a relative motion between the second portion and the third portion is at least partially controlled in a second range of frequencies by the second active suspension system, and wherein the second range of frequencies is different from the first range of frequencies. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
