1. A pedal emulator assembly comprising:
a housing defined by a pair of sidewalls, a first end wall and a second end wall;
a pedal arm having a pedal pad and having a pair of opposing walls, the pedal arm pivotally coupled the housing such that the pair of opposing walls are movable relative to the pair of sidewalls thereby defining a cavity by the pair of opposing walls and the housing;
a lower arm having a spring retaining portion formed therein;
a lever arm pivotally coupled to the housing, the lever arm further including:
a spring receiving portion; and
an engagement surface configured to slidably engage with a portion of the pedal arm, the engagement surface having a non-linear profile that extends a length between a first end positioned at a distal end of the lever arm and a second end of the lever arm, the non-linear profile configured to provide a different force characteristic based on an engagement position of contact between the portion of the pedal arm and the engagement surface substantially along the length of the non-linear profile based on a load applied to the pedal pad, the engagement surface is positioned to be enclosed within the cavity; and
a spring carrier including a compressible member extending between the spring receiving portion and the spring retaining portion,
wherein, when the load is a first predetermined load applied to the pedal pad, the pedal arm drives the lever arm into the compressible member such that the compressible member compresses into an at least partially compressed state to generate a first return force on the pedal pad.
