Mistake-pedal-preventing pedal system for vehicle

The invention discloses a mistake-pedal-preventing pedal system for a vehicle. The mistake-pedal-preventing pedal system comprises a base, a brake pedal and an accelerator pedal, and further comprises a mistake-pedal-preventing pedal mechanism comprising an attraction iron core, a driven iron core, a coil, a controller, an angle displacement sensor and a return spring, wherein the attraction iron core is fixedly arranged in the brake pedal; the driven iron core is assembled in the accelerator pedal; the driven iron core synchronously rotates and axially slides in the radial direction relative to the accelerator pedal; engaged parts are arranged on opposite ends of the attraction iron core and the driven iron core; the return spring is connected between the other end of the driven iron core and the accelerator pedal; the coil is wound on the attraction iron core; the angle displacement sensor is mounted on the driven iron core; the coil and the angular displacement sensor are electrically connected with the controller respectively. The mistake-pedal-preventing pedal system disclosed by the invention is simple, accurate to judge, quick to respond, easy to mount, capable of greatly reducing a traffic accident due to the fact that the accelerator pedal is pedaled as a brake pedal by a driver under an emergency circumstance, and good in expected effect.
