A mobility device that can accommodate speed sensitive steering, adaptive speed control, a wide weight range of users, an abrupt change in weight, traction control, active stabilization that can affect the acceleration range of the mobility device and minimize back falls, and enhanced redundancy that can affect the reliability and safety of the mobility device.

A powered wheelchair is operated by sensor-based control pads that include force transducers to produce a variable output signal that is proportional to a varying force applied. The control pad provides an analog-type output that provides a variable speed signal to a controller to operate the wheelchair at a variable speed in both forward/reverse directions and in right or left turning directions.

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 powered balancing mobility device that can provide the user the ability to safely navigate expected environments of daily living including the ability to maneuver in confined spaces and to climb curbs, stairs, and other obstacles, and to travel safely and comfortably in vehicles. The mobility device can provide elevated, balanced travel.

A small electric vehicle includes: a body with a forward, backward, and a width direction; left and right driving wheels in the width direction of the body; free wheels, apart from the driving wheels, in the forward and backward direction; left and right motors to respectively transmit power to the left and right driving wheels; left and right rotation speed sensors detecting rotation speeds of the respective motors; an operation unit with an operation element; and a control unit controlling the motors according to an operation on the operation element, the control unit calculates target rotation speeds of the motors, based on a target vehicle speed provided by an operation position of the operation element, and on a target vehicle angular velocity provided by the operation position of the operation element and by the actual speed of the vehicle, and control the left and right motors such that actual rotation speeds of the motors follow the respective target rotation speeds.

A small electric vehicle includes: left and right motors connected so as to respectively transmit power to left and right driving wheels; left and right rotation speed sensors; an inclination sensor; a joystick-type operation element; and a control unit, wherein it is configured to calculate target rotation speeds of the left and right motors, based on a target vehicle speed provided by an inclination angle in consideration of the pitch angle and the roll angle detected through the inclination sensor and by an operation position of the operation element, and on a target vehicle angular velocity provided by the inclination angle, by the operation position of the operation element and by the actual speed of the vehicle, and control the left and right motors such that actual rotation speeds of the left and right motors follow the respective target rotation speeds.

A small electric vehicle includes: a vehicle body that has a forward and backward direction, and a width direction; left and right driving wheels provided apart in the width direction of the vehicle body; left and right motors connected so as to respectively transmit power to the left and right driving wheels; an operation unit that includes a joystick-type operation piece; and a control unit for controlling the left and right motors according to an amount of operation on the operation piece, wherein the control unit is configured to execute deceleration and stop control when the operation piece is returned to the neutral position during travel, and execute rapid stop control irrespective of an amount of operation in left and right directions when the operation piece is tilted backward during forward travel at a speed equal to or greater than a predetermined threshold.

Provided is a moving body. A control device of the moving body starts a first control processing that moves a movement part so that a posture of a base with respect to a passenger seat becomes a predetermined posture with an auxiliary grounding part lowered and grounded. The control device starts a second control processing that lifts the auxiliary grounding part with respect to the base and a third control processing that moves the movement part 2 so as to stabilize a posture of the passenger seat after a delay from the start of the first control processing.

A powered wheelchair is operated by sensor-based control pads that include force transducers to produce a variable output signal that is proportional to a varying force applied. The control pad provides an analog-type output that provides a variable speed signal to a controller to operate the wheelchair at a variable speed in both forward/reverse directions and in right or left turning directions.

A power management system and a power management method for wireless power supply are provided. The power management system includes a first electric auxiliary vehicle, a second electric auxiliary vehicle, a management device and a wireless charging platform. When the first electric auxiliary vehicle is located within a wireless charging range of the wireless charging platform, the wireless charging platform generates a password and provides the password and a user identification code of the first electric auxiliary vehicle to the management device. The first electric auxiliary vehicle communicates with the management device according to the user identification code to receive the password from the management device and displays the password, and activates a wireless power supply function according to a verification operation of the password and the user identification code, thereby providing power to the second electric auxiliary vehicle by a wireless power supply manner.
