ABSTRACT:
A method of setting values of a multiplicity of performance parameters of a power driven wheelchair into a controller 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 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.
