A pedal device which can alleviate fatigue of a driver's ankle due to frequent acceleration by varying the amount of reaction force applied when the driver presses and releases a pedal by adjusting a pre-compression force against a return spring disposed at a hinged portion of a pedal arm and adjusting a friction force on a pivot end of the pedal arm. The pedal device includes a housing fixed to a car body, an arm hinged to the housing, an elastic member disposed at the hinged portion between the housing and the pedal arm, a pedal effort adjusting unit disposed at the pedal arm and pressing an end of the elastic member, and a hysteresis adjusting unit movably disposed at the housing to press a pivot end of the pedal arm and adjusting the amount of change in stroke-to-pedal effort when the pedal arm operates.

Pedal device with function of adjusting pedal effort and hysteresis

An apparatus for generating hysteresis of an electronic accelerator pedal for a vehicle is provided, which includes a pedal arm that is pivotably connected to a housing; a friction block that is provided to be in contact with an inner wall of the housing; a friction block hole that 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; a spring seat that is provided to be seated on the friction block; and an inner spring and an outer spring each of which one end is supported against the upper inner surface of the housing and the other is supported by the spring seat.
