Method and apparatus for setting or modifying programmable parameters in power driven wheelchair
First Claim
1. An apparatus associated with a power driven wheelchair comprising:
- a display device coupled to the wheelchair;
one or more fault detection mechanisms coupled to the wheelchair that are configured to output a plurality of fault codes each associated with a given wheelchair operating condition;
a stored collection of diagnostic information associated with each fault code;
a diagnostic information request selector associated with the display device;
a microcontroller that, in response to actuation of the diagnostic information request selector, selects diagnostic information associated with a fault code presently displayed on the display device and displays the diagnostic information on the display 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.
