A device for preventing mistaken use of accelerator as brake

Abstract

The invention provides a device for preventing an accelerator from being mistakenly regarded as a brake and relates to an automotive electronic accelerator and a brake. The problem of throttling back while the accelerator is mistakenly regarded as the brake to cause braking is not solved well by adopting existing various methods, and meanwhile the problem that the brake cannot return and the accelerator cannot be treaded when the brake is about to lift is not considered in existing inventions. The problems are also the main causes that existing automobile production manufacturer do not adopt the technical schemes of the inventions. An automobile body comprises an accelerator pedal, wherein a position sensor is arranged on the accelerator pedal, a steel wire rope I is connected to the accelerator pedal is wound around an internal reel in a winder, a steel wire rope II is fixedly connected to the top end of the outer surface of the winder, penetrates through a pulley I, a pulley II and a pulley III and then is connected to a brake pedal support, a unidirectional rotting damper is connected with the brake pedal support, a brake pedal is arranged on the brake pedal support, and the winder is arranged between the accelerator pedal and the pulley I. The device is used for preventing the accelerator from being mistakenly regarded as the brake.

Description

technical field [0001] The invention relates to a device for preventing an accelerator from being mistakenly used as a brake, and relates to an automobile electronic accelerator and brake. Background technique [0002] With the development of science and technology and the continuous improvement of national life, automobiles are gradually entering every family as one of the main means of transportation. Due to the new non-professional drivers driving on the road, accidents of drivers mistakenly using the accelerator as the brake happen from time to time , has brought great harm to people's lives and property safety. The brake and accelerator of the car are controlled by the right foot, and the position of the brake and the accelerator is very close. When the car needs to speed up in normal driving, the correct way is to step on the accelerator pedal gradually. Car driving experiments have proved that stepping on the accelerator pedal to the bottom cannot instantly increase ...

AI Technical Summary

Problems solved by technology

When an emergency brake is required in a critical situation ahead of the vehicle, the correct operation is to lift the right foot from the accelerator pedal and step on the brake pedal, but some drivers, especially new drivers, may put The accelerator was accidentally stepped on when the brakes were slammed, resulting in a traffic accident that should have been avoided

[0003] In the current literature and patents published on the anti-acceleration system of automobiles, they are mainly divided into three categories: the first category is to change the structure of the existing brake, operate the left and right feet separately, and control the accelerator with one foot and the brake with the other. The disadvantage of this type of device is that in an emergency state, it is still easy to make mistakes in the power of the left and right feet, and it is difficult for people to adapt to the current driving habits; the second type is to detect the depressing speed of the accelerator pedal through an electronic sensor. Stop refueling when the pedaling speed exceeds the normal range

The disadvantage of this type of device is that it does not brake while stopping refueling, and there is still the possibility of accidents when the car continues to move forward; The disadvantage of the method is that the emergency brake cannot be set to be a reasonable distance between the obstacle and the car, because sometimes the car needs to approach the object during driving; when the existing method mistakenly uses the accelerator as the brake, it can only be controlled by linkage Braking and braking cannot make the accelerator return to the idle state. It is equivalent to stepping on the accelerator and stepping on the brake at the same time. The car is still in the state of driving with a large accelerator, which offsets part of the braking force. , due to the function of the retractor, there is a problem that the position of the brake pedal is locked and cannot be lifted

In short, the current various methods have not solved the problem of stepping on the brakes and lifting the accelerator when the accelerator is mistakenly used as a brake. The existing patents only consider the situation of quickly stepping on the accelerator when stepping on the accelerator by mistake, and do not consider quickly lifting the brake. In the case of the pedal, the problem that the brake cannot be retracted and the accelerator cannot be stepped on when the brake is lifted quickly has not been solved.

This is also the main reason why the current automobile manufacturers have not adopted their technical solutions.
