Abstract

A system used to control the orientation of a vehicle'"'"'s suspension. The system includes a control system receiving input data from a plurality of sensors concerning the relative motion, speed, and orientation of the vehicle. The control system is configured to process the input data and actively control the orientation of the suspension system by selecting a suitable driver speed and tilt angle according to external conditions.

Claims

1. A system for controlling a suspension of a vehicle, the suspension comprising first and second rocker arms associated with respective first and second wheels, the system comprising:

an adjustable connecting rod connected to the first and second rocker arms;

a sensor operably associated with the vehicle for sensing at least one of an orientation, a speed, and a motion of the vehicle;

a control system in communication with the sensor and being configured to adjust a tilt angle of the vehicle in response to the sensor; and

a driver connected to the first and second rocker arms and in operable communication with the control system and suspension of the vehicle, the driver configured to adjust the tilt angle of the suspension in response to the control system,

wherein the sensor is at least one of a pneumatic and a hydraulic device.

2. The system of claim 1, wherein the driver is at least one of a pneumatic, a hydraulic, an electric, and a magnetic device.

3. The system of claim 1, wherein the control system is automated, so as to receive and process input data from the sensor without input from a user.

4. The system of claim 1, wherein the control system automatically induces movement of the driver to adjust the tilt angle.

5. The system of claim 4, wherein the control system accounts for the relative orientation of the vehicle in determining the tilt angle.

6. The system of claim 1, wherein the control system adjusts the speed of the driver and the tilt angle of the vehicle according to external conditions, so as to provide a safe and smooth transition between movements of the suspension.

7. The system of claim 1, wherein the control system may be overridden by at least one of an automatic override and a manual override, the manual override requiring input from a user.

8. The system of claim 1, wherein the driver extends longitudinally between the first and second rocker arms and is at least one of an actuator and an electro-mechanical device.

9. The system of claim 1, wherein the control system actively changes the orientation of the suspension.

10. The system of claim 1, wherein the control system permits user customization, wherein a user manually selects performance characteristics of the suspension.

11. The system of claim 10, wherein modification of the performance characteristics is performed by the user while operating the vehicle.

12. The system of claim 1, wherein the control system and driver are operably coupled to a front wheel.

13. The system of claim 1, wherein the control system and driver are operably coupled to a back wheel.

14. The system of claim 1, wherein the control system returns the vehicle to a vertical position in the event of a discrepancy with the sensor.
