A system, method, and device for operations of an electrically motorized vehicle. The vehicle can utilize an electrically motorized wheel to convert a non-motorized wheeled vehicle to an electrically motorized wheeled vehicle. One system includes a server in communication with the device of each of a plurality of electrically motorized wheels, the server operable to track a position of each of the electrically motorized wheels and communicate the position thereof to a transportation network.

A motion-based push activation power assist system for manual wheelchairs. The system uses motion-based measurements to determine when the user applies a push to the wheelchair handrims and brakes with the handrims. The push recognition activates a drive system that provides an assistive driving force-pulse to the wheelchair to reduce the demand on the user during propulsion. The brake recognition deactivates the power assist. The provided power assist is proportional to the sensed push and can be modulated to different proportional settings.

An electrical power assistance device designed to be removably coupled to existing transport wheelchairs to provide electric power to aid in transportation of a person sitting in the wheelchair, while being detachable to allow the transport chair to fold up for easy storage in a car or other vehicle. The electrical power assistance device includes a motor powered by a rechargeable battery, where the motor drives an internal shaft which rotates a pair of friction wheels. A clutch, provided on a separate axle coupled to the friction wheels by eccentric disks, allows the friction wheels to engage or disengage with the rear wheels of the transport wheelchair.

An electric wheelchair control system is adapted to control a wheelchair and comprises a sensing assembly, an inertial sensor, a controller, a motor driver, and a three-phase AC motor. The sensing assembly is configured to detect an external force applied to the wheelchair and generate a first sensed signal based thereon. The inertial sensor is configured to detect an inclination of the wheelchair and generate a second sensed signal based thereon. The controller selectively outputs a PWM braking signal to the motor driver according to the first sensed signal and the second sensed signal, and the PWM braking signal includes an upper arm braking signal and a lower arm braking signal, wherein the upper arm braking signal and the lower arm braking signal have the same duty cycle and when the upper arm braking signal is at a high level, the lower arm braking signal is at a low level.

A wheelchair can comprise a frame and a plurality of wheels rotatably attached to the frame, and a motor coupled to the frame. A power source can be configured to power the motor. A drive shaft can be coupled to the motor. A first sprocket can be coupled to the drive shaft. A second sprocket can be configured to be rotationally fixed to a wheel of the plurality of wheels. A drive belt or chain can extend between the first sprocket and the second sprocket. An input device can be configured to receive an input from an operator and, in response to receiving the input, cause the motor to rotate.

An electrically assisted wheelchair includes a controller that obtains an inclination assist value by correcting the assist value when a road surface is inclined in a left-right direction of the seat, and performs a downhill turning preventing operation of causing the wheelchair body to travel straight by applying right auxiliary power and left auxiliary power corresponding to the inclination assist value. The controller adjusts the right auxiliary power and the left auxiliary power by correcting the inclination assist value based on a hand rim operation of the user to operate at least one of the right hand rim and the left hand rim in the downhill turning preventing operation.

Provided is a wheelchair that can be operated easily with either a right or left hand. The wheelchair is provided with; right and left handrims; a rotary shaft for transmitting a rotational force generated by a handrim on one side to a wheel on the opposite side via a drive mechanism; and a wheel hub for transmitting the rotational force generated by the handrim on the one side to the wheel on the same side via the drive mechanism, wherein the drive mechanism includes two pairs of right and left sensors respectively disposed on an outer surface of each of the handrims, a first non-excitation electromagnetic clutch for transmitting the rotational force to the right wheel, a second non-excitation electromagnetic clutch for transmitting the rotational force to the wheel on the opposite side, and a third non-excitation electromagnetic clutch for transmitting the rotational force to the left wheel.
