A misoperation safety protection device for an automotive accelerator pedal is added on an automobile and is used for preventing a safety accident caused by a misoperation to the accelerator pedal which is mistakenly used as a brake pedal. The misoperation safety protection device comprises the components of an accelerator pedal speed sensor, an automatic braking device and an electric control device. The misoperation safety protection device is characterized in that the accelerator pedal speed sensor is a mechanical-photoelectric sensor; the automatic braking device comprises a braking spring, a control electromagnet, a pawl, a braking lever and a braking connecting rod. The pedal speed sensor comprises a rotary photoelectric encoder. One end of the braking lever is provided with a reset pedal 241. A hinge for hinging the braking connecting rod with the brake pedal is an open hinge. The misoperation safety protection device has advantages of simple structure, simple mounting, no effect on an original automobile structure, no cab space occupation, no effect on normal operation, no requirement for operation habit change of an operator, high response speed, high reliability, effective capability of restoring normal driving through one-foot resetting, easy popularization, relatively high practical value and relatively high social benefit.
