Abstract: An apparatus for measuring the performance of an accelerator pedal of an automotive vehicle includes a torso member which is seated in a driving position of an automobile. The torso member has a leg mechanism connected thereto for actuating an accelerator pedal. The torso member has a hip portion which rotates about an axis which remains fixed relative to the seat despite the position of the leg. Various transducers are strategically located to measure certain performance characteristics of the accelerator pedal such as the force for operating the pedal, the angle of the foot while operating the pedal, and pedal scrub. Because the lengths of the members and the angles of the joints are measured, the movement of each portion of the apparatus are related to movement relative to the axis.
