  • Patent number: 12235669
    Abstract: An electronic pedal device includes an accelerator pedal module and a brake pedal module that operate in a pressure operation manner, whereby a driver may operate the same with a small force. The driver may easily recognize the operational state of the pedal based on a haptic signal generated during operation of the pedal. Because operation of the pedal is detected through a dual detecting structure using a Hall sensor and a pressure sensor, safety may be further ensured during operation of the pedal.
