Abstract
An adjustable pedal assembly (10) for controlling step-over between adjacent pedal levers (18,32). A first pedal lever (18) is supported for rotation about an operational axis (A). A first adjustment mechanism (20) includes a first motor (26) to adjust the first pedal lever (18) between a first plurality of adjusted positions. A second pedal lever (32) is supported for rotation about a second operational axis (B). A second adjustment mechanism (40) includes a second motor (48) to adjust the second pedal lever (32) between a second plurality of adjusted positions. Each of the motors (26,48) is a brushless DC motor comprising a motor shaft (54,60), a plurality of sensors (H1,H1',H2,H2',H3,H3') adjacent to the motor shaft (54,60), and a plurality of windings (W) surrounding the motor shaft (54,60). The plurality of sensors (H1,H1',H2,H2',H3,H3')of each motor (26,48) generates a position signal indicating a position of each motor (26,48). When the position signals are unequal, step-over has occurred. In response, a coordinator (66) repositions at least one of the motor shafts (54,60) by holding an output signal sent to phases (A,B,C) of the windings (W) at a steady state until the position signals are equal.
