Abstract: A method of programming parameters of a power driven wheelchair for a plurality of drive modes comprises: displaying a menu image on an interactive display screen, the menu image including settings of a plurality of wheelchair parameters for a plurality of drive modes of the wheelchair; selecting a wheelchair parameter for a drive mode from the displayed menu image; and programming the setting of the selected wheelchair parameter to a desired setting.

Abstract: A power driven wheelchair and a method for operating same are provided. In one embodiment, the power driven wheelchair includes a system controller with a main controller, a storage device, and at least one input device, a motor assembly, and a common bus. The motor assembly may include a drive motor, a local controller, and a sensor sensing a condition associated with the drive motor and in communication with the local controller. In another embodiment, the power driven wheelchair includes the system controller, an actuator assembly, and the common bus. The actuator assembly may include an actuator mechanism, a local controller, and a sensor sensing a condition associated with the actuator mechanism and in communication with the local controller. Multiple embodiments of the method are related to controlling various arrangements of motor assemblies or actuator assemblies.

Abstract: A method and apparatus for setting or modifying a programmable operating parameter associated with a power driven wheelchair is provided. In one embodiment, the method includes: a) operating a user interface device associated with a power driven wheelchair in a programming mode, b) selecting a programmable operating parameter associated with operation of the power driven wheelchair using the user interface device, c) selecting a value for the programmable operating parameter using the user interface device, and d) saving the selected value for the programmable operating parameter in a portion of a storage device associated with the power driven wheelchair using the user interface device. A method and apparatus for selecting one or more programmable parameter sets from a portable storage medium and saving the selected sets to a local storage device associated with a power driven wheelchair and vice versa is also provided.

Abstract: An apparatus and method for providing help information on a display device associated with a power driven wheelchair is provided. In one embodiment, the method includes: a) displaying screen content displayed on the display device during operation or support of the power driven wheelchair, b) detecting selective activation of a first input device, c) in response to detection of the first input device activation, selecting help information content from a collection of help information, the selected help information content being contextually related to the screen content displayed on the display device, and d) displaying the contextually-related help information content on the display device. In one embodiment, the apparatus includes: a display device, a first input device, and a microcontroller in operative communication with the display device and the first input device.

Abstract: A collection of diagnostic and troubleshooting information associated with a power driven wheelchair is stored for access by a microcontroller to be displayed to a user to assist in troubleshooting the power driven wheelchair. A log of fault codes transmitted by various fault-detecting mechanisms is compiled. A user may request display of diagnostic information associated with a selected fault code. The operating instructions of a power driven wheelchair may be updated by using portable storage media onto which a latest version of operating instructions is loaded to transfer the updated operating instructions to wheelchair controller memory. The calibration of a power driven wheelchair can be simplified by providing functionality within the wheelchair controller to change calibration parameters or to transfer calibration parameters from portable storage media.
