Abstract: A motorized wheelchair is advantageously provided with a rate-of-turn feedback sensor and with forward/reverse motion, lateral motion, and vertical motion acceleration feedback sensors that are integrated into a closed-loop wheelchair servo control system to differentially control the rotational speed of wheelchair opposed motor-driven wheels and thereby obtain improved wheelchair motion stability through reduction/elimination of likely wheelchair spin-out and wheelchair tipping during wheelchair operation.

Abstract: A power wheelchair is provided having opposing drive wheels wherein the axles of the drive wheels are coupled directly to the rotor of drive motors. These motors are brushless motors, wherein each has a brake located within the motor housing which acts directly on the rotor. The brake is a fail-safe brake since it is in a non-engaged position when activated. In another embodiment of the invention, permanent magnet rings of the motor have been magnetized so as to generate a trapezoidal wave function corresponding to the relative displacement of the rotor to the stator. This wave function is used by a microprocessor to independently control the two opposing drive wheels which may be rear drive wheels, mid-drive wheels or front drive wheels.

Abstract: A method of setting values of a multiplicity of performance parameters of a power driven wheelchair into a controller thereof comprises the steps of: grouping the multiplicity of performance parameters into at least two groups; for each group, (a) establishing a corresponding relationship between a selected performance parameter and each of the other performance parameters; and (b) presetting the established relationships into the controller; determining a value for each selected performance parameter based on the user's capabilities of operating the wheelchair; entering the determined value for each selected performance parameter into the controller; deriving automatically by the controller for each group a value for each of the other performance parameters based on the entered value of the selected performance parameter and the corresponding established relationships of each of the other performance parameters with the selected performance parameter; and storing the entered and derived values of the performance parameters into the controller.

Abstract: A drive motor assembly for a power driven wheelchair comprising: a stator housing for containing field coils of a stator of the motor assembly; at least one sensor disposed in the stator housing for sensing rotation of the motor; a memory storing motor error parameter data including data of errors of the at least one sensor, the memory being embedded in the stator housing; and a connection for accessing the error parameter data of the memory from the stator housing. The motor error parameter data may be accessed from the embedded memory of the drive motor by a programmed motor controller for use in controlling the drive motor. Also, the motor error parameter data may be embedded in the drive motor by the steps of: controlling the motor through at least one predetermined drive pattern; sensing motor rotation during the drive pattern and generating signals representative thereof, deriving error parameter data of the drive motor from the generated signals; programming a memory with the derived error parameter data; and embedding the memory in the drive motor.
