초록 ▼

A wheeled board device with forward and rearward in-line wheel structures attached to a user platform. The forward wheel may have a forward tilt axle or be otherwise direction-biased to permit lean-based turning. The rear wheel may be singular or comprise two tires or the like and be motorized or not. The wheels are preferably large to more readily handle surface irregularities. A self-balancing wheelie mode is disclosed in one embodiment. Other embodiments include placement of the forward tilt axle within or without the envelope of the front wheel. The user platform is below the top of the rear wheel and preferably near the axis of the rear wheel, among other features.

1. A wheeled board device, comprising: a board that is longer than widea first wheel coupled towards a front of the board;a second wheel coupled through the board, rearward of and substantially in-line with the first wheel;a motor that drives the second wheel;a position sensor that detects a position of the board; andan electronic control circuit;wherein the device is configured such that when the first wheel is off the ground, the motor may drive the second wheel based on board position data from the position sensor. 2. The device of claim 1, wherein the driving of the second wheel is conducted through an auto-balancing feedback control loop based on the tilt angle position of the board as detected by the position sensor. 3. The device of claim 1, further comprising a pressure sensor for detecting the pressure from a rider asserted forward of the second wheel. 4. The device of claim 1, further comprising a pressure sensor coupled to the front wheel that detects when the front wheel is in contact with the ground. 5. The device of claim 2, wherein the driving of the second wheel via auto-balancing feedback control loop is initiated when the first wheel is off the ground for a predefined period of time. 6. The device of claim 2, wherein the driving of the second wheel via auto-balancing feedback control loop is initiated when the board is maintained above a threshold tilt angle for a predefined period of time. 7. The device of claim 5, wherein the auto-balancing feedback control loop driving of the second wheel is disabled and the device returns to manual propulsion when at least one of the following occurs: (a) the front wheel is brought back into contact with the ground and (b) the board is lowered below a threshold tilt angle. 8. The device of claim 1, wherein the platform includes a first section for a first foot located between the first and second wheels and a second section for a second foot located rearward of the second wheel. 9. The device of claim 1, wherein the first wheel is mounted in a biased-direction arrangement. 10. A wheeled board device, comprising: a board that is longer than widea first wheel coupled towards a front of the board;a second wheel coupled through the board, rearward of and substantially in-line with the first wheel;a motor that drives the second wheel;a position sensor; andan electronic control circuit;wherein the device is configured for a manual mode of operation and an auto-balancing mode of operation with auto-balancing occurring about the second wheel. 11. The device of claim 10, further comprising a pressure sensor for detecting the weight of a rider asserted forward of the second wheel. 12. The device of claim 10, further comprising a pressure sensor coupled to the front wheel that detects when the front wheel is in contact with the ground. 13. The device of claim 11, wherein the driving of the second wheel in auto-balancing mode is initiated when the first wheel is off the ground for a predefined period of time. 14. The device of claim 11, wherein the driving of the second wheel via auto-balancing mode is initiated when the board is maintained above a threshold tilt angle. 15. The device of claim 14, wherein the auto-balancing mode driving of the second wheel is disabled and the device returns to manual propulsion when at least one of the following occurs: (a) the front wheel is brought back into contact with the ground and (b) the board is lowered below a threshold tilt angle. 16. The device of claim 10, wherein the platform includes a first section for a first foot located between the first and second wheels and a second section for a second foot located rearward of the second wheel. 17. The device of claim 10, wherein the first wheel is mounted in a biased-direction arrangement. 18. A wheeled board device, comprising: a board that is longer than widea first wheel coupled towards a front of the board in a biased-direction arrangement;a second wheel coupled through the board, rearward of and substantially in-line with the first wheel;a motor, coupled to the second wheel, that drives the second wheel;a pressure sensor located forward of the second wheel that detects pressure asserted by a rider forward of the second wheel; andan electronic control circuit coupled to the pressure sensor and the motor;wherein the driving of the second wheel by the motor is based in part on data from the pressure sensor. 19. The device of claim 18, further comprising a position sensor that detects a tilt angle of the board, and wherein the device is configured for (a) a manual mode of operation and (b) an auto-balancing mode of operation when the first wheel is off the ground, the auto-balancing mode of operation occurring when the first wheel is off the ground, the driving of the second wheel during auto-balancing mode of operation being based, at least in part, on the tilt angle of the platform as detected by the position sensor. 20. The device of claim 18, wherein the platform includes a first section for a first foot located between the first and second wheels and a second section for a second foot located rearward of the second wheel.
