Description

The present invention relates to a brake and an accelerator misstep prevention device that prevents sudden start or acceleration by accidentally stepping on the accelerator pedal with the intention of stepping on the brake pedal, and is particularly easy to retrofit and returns the wrong accelerator pedal. It is related to a device that has a mechanism and can correct mistakes in braking and accelerator depression.

As a device for preventing mistakes in stepping on the brake and the accelerator, a brake pedal cover in which the brake pedal is covered with a cover protruding to the left side has been proposed (see, for example, Patent Document 1). In this brake pedal cover, the brake pedal is widened and the brake pedal is stepped on with the left foot so that the brake pedal is not mistakenly stepped on.

As another brake and accelerator depression prevention device, a pedal operation supplement device including a tread plate member that covers a part between the accelerator pedal and the brake pedal has been proposed (see, for example, Patent Document 2). In this pedal operation supplementary device, when parking, the foot can be placed on the accelerator pedal and the brake pedal at the same time via the tread plate member, and lateral movement due to pedal operation is eliminated so that the pedal is not mistakenly stepped on. ..

Further, as another brake and accelerator stepping error prevention device, a stepping error prevention countermeasure device in which a base made of a support is mounted on the accelerator pedal has been proposed (see, for example, Patent Document 3). With this misstep accident prevention device, if you raise your right foot and step on the accelerator as if you were stepping on the brake, the platform will interfere and you will not be able to step on the accelerator pedal.

Although it is not a stepping error prevention device, as a brake and accelerator stepping error prevention system, when an accelerator stepping error is detected, the corresponding control content among the multiple control levels for suppressing sudden acceleration of the vehicle is used as the vehicle control means. A program for a device for dealing with missteps to be output has been proposed (see, for example, Patent Document 4). In this program for the device for dealing with mistakes in stepping, when an error in stepping on the accelerator is detected, the control content is determined, and the acceleration is set to 0.2 times the amount of depression of the accelerator or zero regardless of the amount of depression of the accelerator. The engine is controlled to do so.

JP-A-2018-177194 (paragraph 0010, FIG. 2) Utility Model Registration No. 3188111 (paragraph 0013, FIG. 1A) JP-A-2018-162048 (paragraph 0012, FIG. 1) Japanese Unexamined Patent Publication No. 2012-166631 (paragraphs 0051, 0052, FIG. 2)

In the brake and accelerator depression prevention device according to Patent Document 1, the brake pedal is widened so that the brake pedal is depressed with the left foot, but the driving school teaches the driver to step on the brake with the right foot. If you suddenly start to step on the brake pedal with your left foot without practicing left foot braking, it is dangerous because you cannot make delicate pedal adjustments. Also, even if you practice left foot braking, your right foot may suddenly step on the accelerator pedal because your body remembers to step on the brake pedal with your right foot.

Furthermore, according to the experience of the inventor, in a panic state, the foot may be stretched, and the accelerator pedal may be stepped on with the right foot and the brake pedal may be stepped on with the left foot at the same time.

In the brake and accelerator depression prevention device according to Patent Document 2, since the foot can be placed on the accelerator pedal and the brake pedal at the same time via the tread plate member, the accelerator pedal and the brake pedal are simultaneously depressed. There is a risk that it will end up.

In the brake and accelerator depression prevention device according to Patent Document 3, when the platform interferes with the accelerator pedal, a new brake is required on the platform, so that the device cannot be retrofitted.

In the brake and accelerator depression prevention system according to Patent Document 4, when the accelerator is strongly depressed, an accelerator depression error is detected and the engine is controlled so as not to accelerate. Therefore, for example, on a highway. When the accelerator must be depressed strongly, such as when entering the main line or when overtaking the vehicle in front of the vehicle in front of the vehicle, it may be judged that the accelerator is depressed incorrectly and acceleration may not be possible.

Therefore, an object of the present invention is to provide a device that solves the above-mentioned problems, can be easily retrofitted, has a mechanism for returning an accelerator pedal that has been mistakenly depressed, and can correct mistakes in pressing the brake and accelerator.

In order to solve the above-mentioned problems, in the invention according to claim 1, the brake and the accelerator depression correction device are provided with a dogleg-shaped lever member for connecting the accelerator pedal and the brake pedal, and a shape protruding to the left side of the brake pedal. It consisted of a wide brake pedal cover. The lever member is attached with a U-shaped accelerator pedal sandwiched at one end (hereinafter referred to as "pinching"), and has an accelerator pedal sandwiching portion, and an annular wide brake pedal cover shaft at the other end. It is equipped with a wearing part. Then, the length of the lever member from the shaft attachment portion of the wide brake pedal cover to the fulcrum is made longer than the length from the accelerator pedal sandwiching portion to the fulcrum.

In the invention according to claim 2, the wide brake pedal cover is provided with a U-shaped brake pedal sandwiching portion.

In the invention according to claim 3, the cushioning member is provided at a position where the fulcrum of the lever member is in contact with the floor surface of the vehicle body (hereinafter referred to as "contact").

According to the invention of claim 1, since the brake and accelerator depression correction device is configured to have a dogleg-shaped lever member that connects the accelerator pedal and the brake pedal, the accelerator pedal and the brake pedal are interlocked with each other. Can be made to. Therefore, according to the invention of claim 1, even if the right foot mistakenly steps on the accelerator pedal with the intention of stepping on the brake pedal, when the brake pedal is stepped on with the left foot, the brake pedal is stepped on in conjunction with the stepping. You can return the accelerator pedal that you made a mistake in pressing.

Here, according to the invention of claim 1, for the lever member, the length from the shaft attachment portion to the fulcrum of the wide brake pedal cover is made longer than the length from the accelerator pedal sandwiching portion to the fulcrum. By stepping on the accelerator pedal together, the accelerator pedal can be raised and the wrong accelerator pedal can be returned by the principle of leverage.

As described above, according to the invention of claim 1, even if the right foot mistakenly steps on the accelerator pedal with the intention of stepping on the brake pedal, when the brake pedal is stepped on with the left foot, the brake is applied and at the same time the accelerator pedal is pressed incorrectly. Because it can be returned, the brake can be applied reliably. Therefore, according to the invention of claim 1, it is possible to prevent an accident in which the brake and the accelerator are stepped on incorrectly, which explains that "the brake was applied but it did not work". That is, according to the invention of claim 1, if the brake is applied but it does not work, the brake pedal is depressed with the left foot, and when the brake is applied, the accelerator pedal that was mistakenly pressed at that time is returned, and the brake and the accelerator are released. You can correct missteps.

Further, according to the invention of claim 1, since the brake and accelerator depression correction device is configured to have a wide brake pedal cover having a shape protruding to the left side of the brake pedal, the existing brake pedal has a wide brake. A pedal cover can be attached to extend the pedal surface of the brake pedal widely to the left. Here, the existing brake pedal is closer to the right side with respect to the steering wheel so that it can be easily stepped on with the right foot. According to the invention of claim 1, a wide brake pedal cover is attached to widen the pedal surface to the left side. Since it is extended, it is possible to easily step on the brake pedal with the left foot.

According to the invention of claim 1, since the brake pedal surface is widely extended to the left side to make it easier to step on the brake pedal with the left foot, the brake pedal can be surely stepped on only by stretching the left foot. Here, the action of pushing the left foot is the same as the way of stepping on the clutch pedal with the left foot without heels, so for those who have experience driving a manual car, for example, elderly people who are prone to accidental depression of the brake and accelerator. It is a movement familiar to people, and the body remembers it. Therefore, in an emergency where you mistakenly step on the brake and accelerator, you can reflexively step on the brake pedal with your left foot.

Further, according to the invention of claim 1, the wide brake pedal cover is attached and the pedal surface is widely extended to the left side. In other words, the pedal surface is widely extended to the left side while maintaining the position of the existing brake pedal. Therefore, in normal times, you can step on the brake pedal with your right foot as before. Therefore, according to the invention of claim 1, even if the stepping error correction device is attached, the pedal can be operated without change in normal times.

In addition, according to the invention of claim 1, since a U-shaped accelerator pedal sandwiching portion is provided at one end of the lever member, the existing accelerator pedal is sandwiched between the accelerator pedal sandwiching portions to sandwich the accelerator pedal. Can be easily attached to.

According to the invention of claim 2, since the wide brake pedal cover is provided with the U-shaped brake pedal sandwiching portion, the existing brake pedal is sandwiched between the brake pedal sandwiching portions, and the brake pedal can be easily attached. Can be attached to.

As described above, according to the first and second aspects of the invention, since the accelerator pedal is sandwiched between the accelerator pedal sandwiching portions and the brake pedal is sandwiched between the brake pedal sandwiching portions, the stepping error correction device can be easily retrofitted. can do.

According to the third aspect of the present invention, since the cushioning member is provided at the position where the fulcrum of the lever member abuts on the floor surface of the vehicle body, the floor surface of the vehicle body is not damaged even if the lever member shifts.

Further, according to the invention of claim 3, since the cushioning member is provided at the position where the fulcrum of the lever member abuts on the floor surface of the vehicle body, the thickness of the cushioning member can be changed to reach different pedals for each vehicle model. It can also correspond to the height.

First, the matters underlying the creation of the present invention will be briefly described. In this invention, from the experience of the inventor stepping on the brake and accelerator incorrectly, specifically, he immediately noticed the error and immediately stepped on the brake pedal with his left foot to avoid an accident, but his right foot was the accelerator. It was created from the experience of being sick because the brakes did not work easily even though it was slow at the start because I kept stepping on the pedal.

From this experience, the inventor realized that even if he noticed a mistake in stepping, he could not take his right foot off the accelerator pedal immediately because his foot was stressed when he panicked. The inventor also noticed that if the accelerator pedal is not released by mistake, it is difficult to apply the brakes just by operating the brakes, which may lead to a mistaken stepping accident.

Therefore, the inventor can apply the brake and return the wrong accelerator pedal at the same time by depressing the brake pedal if the accelerator pedal and the brake pedal can be connected by using the principle of leverage. He discovered and created this invention.

FIG. 5C is an image diagram of a state in which the brake pedal B is correctly depressed with the right foot and a state in which the wide brake pedal cover 3 is depressed with the left foot because the brake is applied but the brake is not effective.

First, the state in which the accelerator pedal A and the brake pedal B are correctly depressed with the right foot will be described. FIG. 5A is an image diagram of a state in which both the accelerator pedal A and the brake pedal B are not depressed. As shown in FIG. 5A, when both the accelerator pedal A and the brake pedal B are not depressed, the accelerator pedal sandwiching portion 21 does not apply force to the accelerator pedal A, and the brake pedal sandwiching portion 31 Is positioned so as not to apply force to the brake pedal B. The accelerator pedal sandwiching portion 21 is positioned with a play provided on the lower side of the accelerator pedal A.

FIG. 5B is an image diagram of a state in which the accelerator pedal A is correctly depressed with the right foot. As shown in FIG. 5 (b), when the accelerator pedal A is correctly stepped on with the right foot, the accelerator pedal A is lowered from the position shown in FIG. 5 (a), and the lever member 2 is displaced clockwise as shown by the arrow. When tilted, the wide brake pedal cover shaft attachment portion 22 is provided with play with respect to the shaft 32, so that the play absorbs the clockwise tilt of the lever member, and the wide brake pedal cover 3 remains in the same position. Be kept. Further, when the lever member 2 is tilted clockwise as shown by an arrow, the accelerator pedal sandwiching portion 21 is also tilted. However, since the accelerator pedal sandwiching portion 21 is provided with play in the thickness direction, the play is acceleratord. It absorbs the inclination of the pedal sandwiching portion 21 and does not interfere with the movement of the accelerator pedal A. Therefore, when the brake and accelerator depression correction device 1 according to the embodiment correctly depresses the accelerator pedal A with the right foot, the accelerator pedal A moves normally and no extra force is applied to the brake pedal B.

FIG. 5C is an image diagram of a state in which the brake pedal B is correctly depressed with the right foot. As shown in FIG. 5 (c), when the brake pedal B is correctly stepped on with the right foot, the brake pedal B is lowered from the position shown in FIG. 5 (a), and the lever member 2 is counterclockwise as shown by the arrow. The position of the accelerator pedal sandwiching portion 21 rises due to the deviation, and the angle also tilts. Since the accelerator pedal sandwiching portion 21 has a play under the accelerator pedal A, the play is the accelerator pedal sandwiching portion. The accelerator pedal A is kept in the same position by absorbing the rise and fall of 21. Therefore, when the brake and accelerator depression correction device 1 according to the embodiment correctly depresses the brake pedal B with the right foot, the brake pedal B moves normally and no extra force is applied to the accelerator pedal A. Therefore, the brake and accelerator depression correction device 1 according to the embodiment does not interfere with the movements of the accelerator pedal A and the brake pedal B as long as the pedals are correctly operated.

Next, a mechanism for returning the accelerator pedal A from a state in which the accelerator pedal A is accidentally stepped on with the intention of stepping on the brake pedal B with the right foot shown in FIG. 5B will be described. FIG. 5C is an image diagram of a state in which the wide brake pedal cover 3 is depressed with the left foot because the brake is applied but the brake is not effective. As shown in FIG. 5 (c), even if the right foot accidentally steps on the accelerator pedal A, when the wide brake pedal cover 3 is stepped on with the left foot, the brake pedal B is lowered, and the accelerator pedal A is lowered by the principle of leverage. It is something that gets up. More specifically, when the wide brake pedal cover 3 is stepped on with the left foot, even if the right foot is stepping on the accelerator pedal A, the lever member 2 is tilted counterclockwise as shown by the arrow due to the principle of leverage. At this time, since the accelerator pedal sandwiching portion 21 also tilts counterclockwise, a force pushing up from below is applied to the accelerator pedal A, and the accelerator pedal A rises.

With regard to the brake and accelerator depression correction device 1 according to the embodiment configured as described above, if the driver thinks that "the brake is applied but it does not work", the driver simply depresses the wide brake pedal cover 3 with his left foot. The wrong accelerator pedal A can be returned to correct the mistaken depression of the brake and accelerator.

In the brake and accelerator depression correction device 1 according to the embodiment, if the driver thinks that "the brake is applied but it does not work", in other words, the driver corrects the brake and accelerator depression error, so that the system There is no worry of malfunction like control.
