An apparatus for preventing an erroneous operation of an electro-motion pedal device in an automobile and methods of use thereof, wherein an engine starting condition, positions of a shift lever and a parking brake activated condition are detected. When a safe condition of a non-moving automobile is detected, power is transmitted to an electro-motion pedal device to allow the pedal to be electronically adjusted, such that an erroneous operation of an electro-motion pedal device that might occur during an automobile in operation can be prevented to thereby avoid an accident in advance.
