A control device for a power assist wheelchair which includes a compensation turning torque calculation unit that calculates a compensation turning torque value for compensating for at least a part of the shortage or excess of the actual turning torque value with respect to the predicted turning torque value, in which the compensation turning torque value is smaller when the vehicle speed is a first speed than when the vehicle speed is a second speed faster than the first speed; a first target current determination unit that determines a target current of the first electric motor based upon the first manual torque value and the compensation turning torque value; and a second target current determination unit that determines a target current of the second electric motor based upon the second manual torque value and the compensation turning torque value.

An electric mobility vehicle in a facility includes a mobility body having a wheel, a driving unit driving the wheel, and a seat for the user, and sensors, and the mobility body has a controller which controls the driving unit for at least one of automatic driving and automatic stopping by using detected data of the sensor, the controller is configured to be able to set a detection cancel area, which is an area where a part of the user can exist in front of the user, the electric mobility vehicle further includes a lower side sensor which detects an object to be avoided from under a footrest surface or from a front end portion of a footrest portion.

A controller for operative connection to a power assisted transport vehicle that is at least partially directed by a human operator in physical contact with the vehicle, the controller including: a contact surface with a deadman switch, a first sensor and a second sensor each responsive to manual actuation of the contact surface, each sensor having a respective first sensor output signal and a second sensor output signal, and a signal processing means adapted to process the first and second output signals, and control the mode of operation of the controller in accordance with the state of the deadman switch.

The invention envisages a sensor system to be placed onto a personal mobility vehicle. The vehicle includes a structured light sensor that senses one or more obstacles and generates a first sensor data, and a first mechanical coupling that couples the structured light sensor to either a base frame onto which the wheels of the vehicle are attached or the skirt of the vehicle. The system also includes a processing unit that receives and processes the first sensor data and determines a depth of one or more obstacles, and further generates a location information of one or more obstacles.

A system 1 for controlling a powered personal mobility vehicle 8. The system includes an input module 2, a processing unit 4, and a motor controller 7. The input module 2 receives manual triggers 3 regarding the movement of the personal mobility vehicle 8. The processing unit 4 processes a location information 5 or a distance information 6 at a given point in time, and further, either generate an automatic trigger 19, and disable or curtail the functioning of the input module 2, or enable the functioning of the input module 2. The location information 5 is defined as a location of an obstacle co-located in an environment in which the personal mobility vehicle 8 is placed or being driven, and the distance information 6 is defined as the distance of the obstacle from the vehicle 8 at a given point in time. The motor controller 7 receives and processes manual triggers 3 or automatic triggers 19 and controls movement of the personal mobility vehicle 8.

A towing module of a personal mobility includes: a main body provided to extend in a vertical direction and in which a battery is mounted: a driving wheel installed on a lower portion of the main body and having a driving motor: a steering handle installed on an upper portion of the main body; and a connector provided in the main body to selectively connect one of various types of modules to be towed. The main body is maintained in a standing state while driving by the connection to the module to be towed. A personal mobility and a control method thereof utilize the towing module.

A mobile wheelchair/chair, especially for the disabled, having a body support system mounted on the casing, a swivel and drive assembly and castors is characterized in that the swivel and drive assembly equipped with drive motor (8) and swivel motor (5) has s form of coupled vertical fixed fork (6) furnished with at least one swivel wheel (7), and seat (3) is mounted on the steering and swivel axis of fixed fork (6), with swivel motor (5) located in the upper part of the steering and swivel column (6a) of fixed fork (6). Casing (1) is equipped with castors (2) in its lower part.

A mobility device positionable between a powered transport position and a powered wheelchair position is provided. The mobility device includes a frame including a pair of side rails, a pair of wheels on each side rail, a distance between each wheel on a corresponding side rail defining a length of the mobility device, a pair of arms coupled to an end of the pair of side rails, and a seat member positioned between the pair of arms. A pair of foot plates is pivotally attached to the pair of side rails and rotatable between an unfolded position in which the foot plate is horizontal and a folded position in which the foot plate is vertical. Each foot plate having a length at least substantially equal to the length of the mobility device.

A motorized mobile system includes a human machine interface (HMI) to provide control instructions to the system. A controller in the system receives the control instructions and generates a control signal, wherein the generated control signal causes one or more components of the motorized mobile system to respond. One or more sensors generate health data related to a user, wherein the health data is stored in a secure memory connected to the controller, and wherein the stored user health data is used to bias the control signal for the motorized mobile system.

A motorized accessory for a wheelchair includes a housing having a top end and a bottom end, a handlebar assembly secured to the top end of the housing, and a wheel assembly coupled to the lower end of the housing. The motorized accessory also includes an electric motor coupled to the wheel assembly that is configured to drive the wheel assembly. In addition, the motorized accessory includes a tow bar assembly having a proximate end coupled to the housing and extending outward to a free distal end, where the free distal end is configured to be removably coupled to the wheelchair. The motorized accessory is configured to latch to the manually driven wheelchair in order to convert the manually driven wheelchair into a motorized wheelchair.
