Patent ID: 8161842

Claim:
An apparatus for generating hysteresis of an electronic accelerator pedal of a vehicle, the apparatus comprising: a pedal arm that is pivotably connected to a housing, and has a friction block mounting groove and a fitting protrusion integrally formed on one end disposed in the housing and a slope on the bottom of the friction block mounting groove; a friction block that is fitted on the fitting protrusion and positioned in the friction block mounting groove to be able to slide on the bottom of the friction block mounting groove, with a portion protruding from the friction block mounting groove being in contact with an inner wall of the housing; a spring seat that is fitted on the fitting protrusion to be seated on the friction block, and has a seat-protrusion surface at the bottom of which is a slope contacting the friction block; and an inner spring and an outer spring each of which one end is supported against an upper inner surface of the housing and the other end is supported by the spring seat, wherein a friction block hole is formed through the friction block to fit the fitting protrusion and has an elliptical shape in the longitudinal direction of the pedal arm such that the friction block fitted on the fitting protrusion slides on the bottom of the friction block mounting groove.
