A multi-phase multi-pole electric machine attached to a vehicle. The multi-phase multi-pole electric machine includes rotor, stator with five phase windings, machine controller, and torque sensors. The machine controller controls the flow of current. The torque sensors sense the torque exerted by the vehicle and transmits the information to the machine controller. The machine controller provides four degree of control through injection of five phase currents and thus providing higher torque.

A method for managing a self-balancing vehicle includes establishing a first Blue Tooth connection with the self-balancing vehicle, acquiring traveling state data of the self-balancing vehicle through the first Blue Tooth connection, determining whether a smart warning mode is enabled, establishing a second Blue Tooth connection with a smart wearable device if the smart warning mode is enabled, acquiring a preset monitored item and a preset warning event, monitoring the monitored item in the traveling state data for determining whether the warning event has occurred, and sending a warning message to the smart wearable device through the second Blue Tooth connection if the warning event has occurred.

A self-balancing transportation device having improved shock absorbing ability and operation. Several embodiments are disclosed including a single wheel or wheel structure device with foot platforms disposed for angular movement about an axis of rotation that is non-collinear with the axis of rotation of the drive wheel. Single and multiple wheel devices are disclosed as well as devices having independently movable foot platforms, and devices having load platforms that rotate independently and are movable longitudinally with respect to one another, among other embodiments.

The disclosed embodiments are directed to a transportation device, such as a skate. The transportation device may include a frame configured to support at least a portion of a user, and a support system configured to support the frame above the ground. The support system may include a first wheel connected to the frame, a second wheel connected to the frame, and a suspension system connected to the frame and positioned between the first and second wheel. The suspension system may include a rear wheel pivotally connected to a first portion of the frame, and a shock absorber connected between the rear wheel and a second portion of the frame. The shock absorber may be configured to dampen movement by the rear wheel with respect to the first portion of the frame.

In some embodiments, an electric scooter comprises a deck configured to support a rider, front and rear wheels, a handlebar assembly that includes a handlebar, a left handle, and a right handle, a steering column that includes a steering tube and the handlebar assembly, and an electric motor configured to provide mechanical power to at least one of the front and the rear wheels. One or more of the steering column, steering tube, handlebar assembly, handlebar, left handle, right handle, and deck can be configured to be detachable and comprise one or more rechargeable battery packs. In addition, one or more of the steering column, steering tube, handlebar assembly, handlebar, left handle, right handle, and deck can be configured to receive one or more removable rechargeable batteries.

A method for controlling an electric vehicle and the electric vehicle are provided. The method includes: under a condition in which the electric vehicle is in unlocked and motor control shielded states, first predetermined information is detected, wherein the first predetermined information is used for indicating that a rider is located on the electric vehicle; the electric vehicle is controlled to switch from the motor control shielded state to a motor control unshielded state; a predetermined control signal is received in the motor control unshielded state; and a motor of the electric vehicle is controlled to rotate according to a rotational speed corresponding to the predetermined control signal. With the disclosure, the problems of complex operation and poor user experience of a manner for controlling the electric vehicle in the related art are solved.

Vehicles having the versatility to be used as farm vehicles while also being able to be used as a transportation method, such as a motorcycle, are provided. The vehicles can generally include a three-wheel configuration in which first and second drive wheels are substantially vertically aligned, and the third wheel is offset from the vertically aligned drive wheels. The third wheel can be aligned with the second wheel, or it can be disposed at a location that is between the first and second wheels while still being offset from the vertical alignment. A tool for performing farming actions is also provided. In some instances the tool can be laterally offset from the vertically aligned wheels, located between the drive wheels, while in other instances the tool can be disposed distal of the rear wheel. Many vehicle and tool configurations are disclosed, as are methods for operating the same.
