An electronic throttle control pedal assembly includes a housing having a friction generating surface, a pedal arm, a spring carrier, and at least one spring. The pedal arm includes a hub portion and a friction generating member. The friction generating member has a lobe connected to a cross member and is positioned on a side surface of the hub portion. The cross member extends within the hub portion. The spring carrier has a friction generating portion. As the pedal arm is depressed, a portion of the spring carrier engages the friction generating portion against the cross member positioned within the hub aperture and pivotally engages a portion of the lobe of the friction generating member against the friction generating surface of the housing thereby creating at least two independent friction generating surfaces to create a hysteresis proportional to the depression of the pedal arm.

Provided is a force feedback apparatus, including a housing, a rotation shaft fixed to the housing, a trigger movably connected to the rotation shaft and movable relative to the housing, and a force feedback assembly. The force feedback assembly includes a driving magnet fixed to a side of the trigger toward the housing, an iron core fixed to the housing and arranged opposite to the driving magnet, and a driving coil wound around the iron core. The driving coil is energized to interact with the driving magnet to generate force feedback on the trigger. The force feedback apparatus requires no additional transmission structure and directly provides force feedback through interaction between two driving elements, thereby realizing timely force feedback on the trigger and reducing the assembly difficulty while simplifying the structure. In addition, forces in two directions can be directly generated on the trigger by changing a driving current.
