An electric vehicle may include a board having two deck portions each configured to receive a foot of a rider, and a wheel assembly disposed between the deck portions. A motor assembly may drive the wheel assembly in response to board orientation and rider presence information. A rider detection mechanism may include one or more strain gauges, and may be configured to detect rider presence and rider weight information. A responsiveness of the motor may be automatically adjusted based on the rider weight information.

The invention relates to a vehicle including a chassis and a pair of wheels supported in spaced apart relationship by the chassis for rotation about a common axis. A pair of drive modules is associated with the respective wheels. The drive modules and the chassis are connected for rotation as a sub-assembly relative to the wheels about the common axis with the centre of mass of the sub-assembly below the common axis in a static equilibrium position. Each of the drive modules is housed substantially within the respective wheel.

The present disclosure relates to a novel portable electric vehicle, which comprises two front-rear folding mechanisms, a left-right folding mechanism, and an operating mechanism, wherein the two front-rear folding mechanisms for supporting a driver are arranged respectively on the left side and the right side of the bottom of the electric vehicle, the rear ends of the front-rear folding mechanisms are both provided with driving wheel mechanisms, and the front ends of the front-rear folding mechanisms are both provided with rotating wheel mechanisms; two ends of the left-right folding mechanism for driving the two front-rear folding mechanisms to get close to each other are connected respectively to the two front-rear folding mechanisms; and the operating mechanism for controlling the running of the electric vehicle is mounted on the left-right folding mechanism. The present disclosure also relates to a method for controlling the drive of the novel portal electric vehicle, which utilizes an Arduino circuit board to control the running of the electric vehicle. The novel portable electric vehicle has the advantages of good driving experience, small size, light weight, convenience in folding and easiness in operation, and belongs to the technical field of electric vehicles.

A self-propelled, one-wheeled vehicle may include a suspension system configured to provide arcuate, generally vertical motion of a board relative to an axle of a central wheel assembly when the vehicle encounters obstacles and bumps on a riding surface. Illustrative suspension systems may include a shock absorber and a swingarm that couple the wheel assembly to the board.

An auxiliary transport vehicle according to the disclosure comprises a drive unit and an attachment that is placed thereon, wherein the drive unit comprises just two wheels with a common axis of rotation and each with an electric drive, an electronic control device and an electrical energy storage device, and wherein the control device is embodied for actuating the drives in such a way that the auxiliary transport vehicle is kept in an upright position, and for autonomously driving the auxiliary transport vehicle to a specifiable destination and for following an external control device. The disclosure also concerns an auxiliary transport system and a method for operating an auxiliary transport vehicle.

A wheelchair having two drive wheels, each provided with a rotary drive motor wherein the value of the drive torque applied by each motor is controlled such as to stabilize the wheelchair, while in motion on the two drive wheels and occupied by a user, in an inclined balance position.

In an inverted pendulum vehicle (10) including a vehicle body frame (12) fitted with a saddle (32) at an upper end thereof; a main wheel (40) combining a plurality of free rollers (44) arranged along a circle such that rotational center lines of the free rollers are each directed along a tangential line of the circle, a pair of drive disks (50) each carrying a plurality of free rollers (52) arranged along a circumferential direction and configured to engage the free rollers of the main wheel, and a pair of drive units (72, 86) including a pair of electric motors (68, 82) for individually driving the drive disks under an inverted pendulum control, the two drive units are positioned one behind the other between the saddle and a rotational center line of the main wheel.

The electrically powered vehicle trailer is a supplemental power system for a trailer. The electrically powered vehicle trailer comprises a trailer, a drive structure, and an energy conversion structure. The drive structure and the energy conversion structure mount on the trailer. The drive structure electrically connects to the energy conversion structure. The drive structure draws electric energy from the energy conversion structure to assist in the acceleration of the trailer. The drive structure converts the mechanical energy that decelerates the trailer into electric energy that is transmitted back to the energy conversion structure. The energy conversion structure converts electromagnetic radiation and the energy received from the drive structure into chemical potential energy. The energy conversion structure converts the chemical potential energy into electric energy that is transmitted to the drive structure. The electrically powered vehicle trailer is independently powered.

A usage detection system for a self-balancing powered unicycle is disclosed. The usage detection system is adapted to detect an indication of intended usage from a user and to provide an indication of intended usage. The indication of intended usage comprises manipulation of the overall unicycle device resulting from preparatory action taken by the user prior to the onset of the intended usage. Operation of the powered unicycle may thus be controlled based on an indication of intended usage from the usage detection system.

The present invention discloses a self-balancing scooter, including a scooter body. The scooter body includes: an upper shell, a middle shell, a lower shell, pedals and bottom plates. The upper shell includes a first upper shell and a second upper shell. The middle shell includes a first middle shell and a second middle shell. The lower shell includes a first lower shell and a second lower shell. The middle shell is located between the upper shell and the lower shell. Two bottom plates are disposed on bottoms of the first lower shell and the second lower shell respectively. The bottom plates are disposed correspondingly to fixing positions of the controller and the power supply. The bottom plates are configured to adapt to sizes of the controller and the power supply.
