Abstract
An accelerator pedal apparatus with a variable pedal effect may include an intermediate bush installed to be moved along an interior space of a pedal housing, a pair of first conductors fixedly installed on one surface of the intermediate bush and a spring plate facing the one surface of the intermediate bush, respectively, a first coil spring installed such that opposite ends of the first coil spring are supported by the first conductors and a third conductor is integrally coupled substantially over an entire surface of the first coil spring, a pair of second conductors fixedly installed on the other surface of the intermediate bush and an end of the interior space of the pedal housing facing the other surface of the intermediate bush, a second coil spring installed such that opposite ends of the second coil spring are supported by the second conductors and a fourth conductor is integrally coupled substantially over an entire surface of the second coil spring, and a controller for controlling supply of a current to the first conductors, a current to the second conductors, directions of the currents, and intensities of the currents.
