<p>A pedal assembly (20) that provides a hysteresis in pedal force-response upon actuation is provided. The pedal assembly includes a housing (32) and a pedal arm (22) that has an end. The end has a rotatable drum that defines a braking surface. The pedal arm is rotatably mounted to the housing. A lever extends from the second end. A brake pad is retained by the housing and has a contact surface that is substantially complementary to the braking surface. The brake pad is adapted to be engaged with the braking surface. A bias spring device is situated between the lever and the brake pad for urging the contact surface of the brake pad into frictional engagement with the braking surface of the drum. A sensor (80) is coupled to the pedal arm to sense the position of the pedal arm.</p> |
