Mistake-pedal-preventing pedal system for vehicle

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a vehicle anti-misstepping pedal system. Background technique [0002] Since the automatic transmission car has greatly reduced the driver's control intensity, the number of cars in the market has increased rapidly in recent years. Since the accelerator pedal and the brake pedal of the car are mainly controlled by the shift operation of one foot (right foot), in an emergency, it is easy for the driver to use the accelerator pedal as the brake pedal and step on it violently, instead of achieving the braking effect of the vehicle. Cause the vehicle to accelerate, so it is easy to cause serious traffic accidents. Reports of such traffic accidents are increasing day by day, accounting for 12.6% of the total number of accidents. How to prevent and correct the driver from stepping on the accelerator pedal by mistake has become one of the important research fields of human-c...

Problems solved by technology

[0008] Although there are many inventions of various types of anti-mistaken pedaling systems, it can be concluded that there are the following problems: some systems can only prevent the accelerator pedal from being further stepped on, and the effect is limited; the principles and technologies of some inventions are feasible. However, some systems judge that the accelerator is stepped on by mistake and directly cut off the engine oil and flameout, which will cause heavy steering and reduce braking performance

[0009] Unfortunately, the above-mentioned existing electromechanical anti-mistaken pedaling inventions generally use servo motors or stepping motors to drive push rods or pull wires to realize the simulated action of "depressing the brake pedal", which will lead to long execution times for system actions , The response speed is slow, and because the use of the motor makes the system composition complicated, more requirements are put forward for the installation of the pedal system

In addition, it should also be noted that different drivers have different pedal control habits, and some drivers even like to drive aggressively, so the anti-mistaken pedaling system should have the ability to be adjusted to adapt to the differences in driving styles of different drivers. However, all of the above Inventions do not have this function, so the actual effect may not be good
