An anti-misstepping pedal system for a vehicle

Abstract

The invention discloses an anti-misstepping pedal system for a vehicle, which includes a base, a brake pedal and an accelerator pedal; and an anti-misstepping pedal mechanism, which includes an attracting iron core, a passive iron core, a coil, a controller, an angular displacement sensor and Return spring; the attracting iron core is fixed in the brake pedal, the passive iron core is assembled in the accelerator pedal, and the passive iron core rotates synchronously in the radial direction and slides relative to the axial direction relative to the accelerator pedal; the attraction iron core and the passive iron core The opposite end forms an occlusal part; the return spring is connected between the other end of the passive iron core and the accelerator pedal; the coil is wound on the attracting iron core, and the angular displacement sensor is installed on the passive iron core. The coil and the angular displacement sensor are connected to the controller respectively. Phase electrical connection. The whole system of the present invention has the advantages of simple structure, accurate judgment, quick response and easy installation, and can greatly reduce traffic accidents caused by the driver mistakenly stepping on the accelerator pedal as a brake pedal in an emergency, and the expected effect is good.

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 step on the accelerator pedal as a brake pedal, which not only does not achieve the braking effect of the vehicle but Cause the vehicle to accelerate, so it is easy to cause serious traffic accidents. The 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's accidental depressing of the accelerator pedal has become one of the important research fields of human-caused ...

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
