Abstract
A pair of first (14) and second (34) pedal levers is pivotally supported for rotation by a support (12). A pair of adjustment mechanisms (21, 41) interconnect the support (12) and the respective pedal levers (14, 34) and include rods (28, 48) for adjusting the operational position of the pedal levers (14, 34) along the rods (28, 48) between a plurality of adjusted positions. A stepper motor (52) and screw (32) unit is attached to the inner end of each rod (28, 48) for moving the respective pedal levers (14, 34) along the respective rods (28, 48). The assembly (10) is characterized by a controller (56) sending pulses of energy to each of the motors (52), measuring the time to reach a predetermined resistance condition of each motor during each pulse, and terminating energy to both motors (52) in response to the time being below a predetermined time period in any pulse to either motor, thereby to synchronize the movement of both pedal levers together.
