Abstract

Various methods, apparatuses, and systems in which a single-track vehicle has a retractable auxiliary-support wheel assembly and a computer control system. In an embodiment, the single-track vehicle has an elongated body. The retractable auxiliary-support wheel assembly mounts on both sides of the elongated body. The computer control system analyzes signals from one or more sensors to dynamically balance the single-track vehicle.

Claims

1. An apparatus, comprising:

a single-track vehicle with an elongated body;

a retractable auxiliary-support wheel assembly mounted on both sides of the elongated body;

a computer control system to analyze signals from one or more sensors to dynamically balance the single-track vehicle; and

a computer controlled steering system to receive a user'"'"'s road intention through a steering wheel, the computer controlled steering system to combine the user'"'"'s road intention input and signals from the one or more sensors to keep the single-track vehicle balanced and to follow an intended path of the user.

2. The apparatus of claim 1, wherein a first sensor comprises a gyroscope.

3. The apparatus of claim 1, wherein a first sensor comprises an accelerometer.

4. The apparatus of claim 1, wherein a first sensor comprises a magnetometer.

5. The apparatus of claim 1, wherein the computer control system balances the single-track vehicle based upon an optimal control algorithm.

6. The apparatus of claim 1, further comprising:

a computer controlled braking subsystem integrated with the computer controlled balance system to maintain balance on the single-track vehicle while braking.

7. The apparatus of claim 6, wherein the computer controlled braking subsystem directs the operation of one or more brake actuators on a front wheel and a back wheel based upon optimal force calculations.

8. The apparatus of claim 1, further comprising:

an electric motor controlled by the computer controlled steering system, wherein a sensor detects a position of the steering wheel to provide an input signal into the computer controlled steering system and a control signal from the computer controlled steering system controls a steering column.

9. The apparatus of claim 1, further comprising:

a rudder; and

an aileron, the computer control system to control position and alignment of the rudder and the aileron to further stabilize the single-track vehicle.

10. The apparatus of claim 1, wherein the computer control system to control steering and leaning angles of the single-track vehicle based upon the signals from the one or more sensors.

11. The apparatus of claim 1, wherein the computer control system to receive an incline surface condition from the one or more sensors and to deploy the retractable auxiliary supporting wheel assembly at calculated angles to keep the vehicle body upright.

12. An apparatus, comprising:

a single-track vehicle with an elongated body and a handle bar;

a retractable auxiliary-support wheel assembly mounted on both sides of the elongated body; and

a computer control system to analyze signals from one or more sensors to dynamically balance the single-track vehicle, wherein the computer control system also receives the user'"'"'s steering intentions from the handle bar to steer the vehicle along the user'"'"'s intended driving path while maintaining the balance of the single track vehicle.
