Description

Accelerator pedal malfunction elimination device

The present invention relates to an apparatus for preventing a vehicle from running away when a driver depresses the accelerator pedal by mistake in stepping on a brake in a vehicle in which the vehicle speed is controlled by operating an accelerator pedal.

In recent years, the majority of automobiles are automatic cars that perform speed control by means of an accelerator and a brake. In this type of automatic vehicle, a beginner or an elderly person may step on the accelerator with the intention of braking, or may excessively step on the accelerator due to a temporary weakness / loss state during a panic such as an accident.

In the above case, since the stepping force and the stepping angle are different between the brake and the accelerator in the first place, when the accelerator is stepped on for the purpose of braking, the state is the same as when the accelerator is fully opened. In recent years, the acceleration response including the power transmission mechanism has been improved in automobiles, so that the automobile runs out of control and a serious accident occurs.

When the accelerator pedal is depressed from a certain position, the accelerator linkage mechanism is released and the accelerator wire is released. The brake pedal is slightly depressed through the motion conversion mechanism.

As a result, in the conventional accelerator pedal malfunction elimination device, if the accelerator pedal depresses beyond a certain position, the accelerator pedal remains depressed and no special operation is required. Had the effect of operating.

However, in the above-described accelerator pedal malfunction elimination device, the brake pedal is operated by the movement of the interlocking rod fixed to the substantially central portion of the accelerator rod constituting the motion conversion mechanism and the action of the interlocking link attached to the brake arm. The moving distance of the interlocking rod was short, and the braking effect was very slight.

That is, the accelerator pedal malfunction elimination device is configured to avoid this malfunction at an extremely early stage when the accelerator pedal malfunction occurs. At the same time, the malfunction of the accelerator pedal is noticed and avoided. The vehicle is braked by performing the initial braking operation, followed by the original braking operation.

In the invention described in Patent Document 2, when the accelerator is depressed more than a certain position, the connection of the accelerator to the throttle valve is released and the engine returns to the idling state, and further depression does not require switching to the brake pedal. The brake pedal is depressed in accordance with the force depressing the accelerator pedal, and the brake can be controlled.

However, when the accelerator is stepped down at a stroke to shift down by kickdown, if the accelerator reaches the position where the connection to the throttle valve is released excessively, there is a possibility that the acceleration will be stopped although it intends to accelerate. there were.

Also, since it has a complicated structure composed of a large number of members, there are problems that the manufacturing cost is high and maintenance is troublesome.

The present invention has been created in view of the above-described problems of the prior art with the object of providing an accelerator pedal malfunction elimination device that can be realized with a simple structure without causing trouble in normal driving. .

That is, the accelerator pedal malfunction elimination device of the present invention is

An accelerator arm 40 that swings relative to the transmission member 20;
Means for prohibiting the swing of the transmission member 20 to which the accelerator arm 40 is pivotally mounted within the normal depression angle of the accelerator arm 40;
When the depression angle of the accelerator arm 40 exceeds the normal range, the means for prohibiting the swinging of the transmission member 20 is released, and the transmission member pressing portion of the accelerator arm 40 pushes the pressed portion of the transmission member for transmission.

Means for releasing the connection of the accelerator arm 40 to the throttle valve when the accelerator arm 40 is further depressed from the stage where the normal depression angle is exceeded;
If the depression angle of the accelerator arm 40 exceeds the normal depression range, the brake arm 10 is swung in the depression direction together with the accelerator arm 40 via the transmission member 20 to apply the brake, and the accelerator arm 40 is further depressed. The accelerator arm 40 is disconnected from the throttle valve and the accelerator is returned.

Further, the invention according to claim 2 is characterized in that, in the accelerator pedal malfunction elimination device, a stopper rod 70 whose one end abuts against the wall surface of the vehicle body is slidably slidably fitted to the transmission member 20, and A lock member 41 is provided for restricting sliding and fixing the stopper rod 70 to the transmission member 20,
The lock member 41 is configured to be unlocked by detecting that the depression angle of the accelerator arm 40 has exceeded the normal range,
Within the normal depression angle of the accelerator arm 40, one end of the stopper rod 70 that cooperates with the transmission member 20 by the lock member 41 abuts against the wall surface of the vehicle body to prevent the transmission member 20 from swinging. The accelerator arm 40 swings with respect to the member 20,
When the depression angle of the accelerator arm 40 exceeds the normal range, this is detected, the lock by the lock member 41 is released, and the transmission member 20 that is free with respect to the stopper rod 70 is pressed by the accelerator arm 40 to cause the accelerator. It swings with the arm 40.

Further, according to the third aspect of the present invention, in the accelerator pedal malfunction elimination device described above, the engagement portion 43A at one end is engaged with and engaged with the engagement hole 71 provided in the stopper rod 70, and the abutment at the other end. A lock lever 43 that is pressed by contact and separation of the contact protrusion 42 provided on the accelerator arm 40 is pivotally attached to the transmission member 20.
While urging the engaging portion 43A at one end toward the stopper rod 70,
The lock member 41 is set by setting the operating position of the lock lever 43 so that the contact protrusion 43B presses the contact portion 43B at the other end when the depression angle of the accelerator arm 40 exceeds the normal range. It is characterized by that.

According to a fourth aspect of the present invention, in the accelerator pedal malfunction elimination device, the stepping angle of the accelerator arm 40 exceeds a normal range, and the means for inhibiting the swinging of the transmission member 20 is released. When the transmission member pressing portion presses the pressed portion of the transmission member and simultaneously swings the transmission member, the front end of the pressing member moves forward from the transmission member, thereby swinging the brake arm 10 by an amount larger than the swing amount of the transmission member. A brake arm pressing portion 90 to be moved is provided on the transmission member.

According to the fifth aspect of the present invention, in the accelerator pedal malfunction elimination device described above, the tip travels on a traveling surface 75 having a height difference provided at the lower end of the stopper rod 70 when the transmission member is moved forward by swinging the transmission member. As a result, the operating lever 92 whose front is swung in the downward direction is pivotally attached to the transmission member 20, and the rear of the pressing rod 94 which is advanced and retracted forward and backward of the transmission member is pivotally attached above the operating lever. When the pressing portion pushes the pressed portion of the transmission member and simultaneously swings the transmission member, the pressing tip of the pressing rod advances forward from the transmission member, so that the brake arm 10 is moved in a larger amount than the swing amount of the transmission member. A feature is that the brake arm pressing portion 90 is made to swing.

According to a sixth aspect of the present invention, in the accelerator pedal malfunction elimination apparatus, the accelerator arm 40 is connected to the throttle valve side arm mechanism 47 on the connection side to the throttle valve and the pedal side arm mechanism 50 on the connection side to the accelerator pedal. As well as dividing
A connection member 53 for connecting both arm pieces is provided,
When the pedal-side arm mechanism 50 of the accelerator arm 40 is further depressed from the stage where the normal depression angle is exceeded, the connection of the throttle member to the throttle valve-side arm mechanism 47 by the connection member 53 is released, thereby The connection to the throttle valve is released.

Further, according to the seventh aspect of the present invention, in the accelerator pedal malfunction elimination device, the engagement portion 55A of the engagement arm 55 fixed to one end of the pivot 54 is connected to the engagement portion 47A provided in the throttle valve side arm mechanism 47. The connecting member 53 that travels on the traveling surface 72 of the upper surface of the stopper rod 70 that engages and the traveling portion 57 of the traveling arm 56 fixed to the other end of the pivot 54 slides on the accelerator arm 40 is connected to the accelerator arm 40. Pivot to the pedal arm mechanism 50,
While urging the engaging portion 55A of the engaging arm 55 toward the engaging direction,
By providing a height difference on the traveling surface 72 of the stopper rod 70 traveling on the traveling portion 57,
When the accelerator arm 40 is further depressed from the stage where the normal depression angle is exceeded and the transmission member 20 moves relative to the stopper rod 70, the connection travels on the traveling surface 72 on the upper surface of the stopper rod 70 along with the movement. The traveling portion 57 of the traveling arm 56 of the member 53 is
The height of the running surface 72 is increased, and the connection member 53 is swung in the direction of releasing the connection with the throttle valve side arm mechanism 47 to release the connection.

According to the eighth aspect of the present invention, in the accelerator pedal malfunction elimination apparatus, the accelerator arm 40 provided with the contact protrusion 42 for pressing the lock lever 43 and the pressing arm 60 have a common pivot 61 to transmit the transmission member. The two

arms

40 and 60 are fixed so as to be freely contactable and separable with a biasing force in the proximity direction.
By using the pressing arm 60 as a pressing portion to the transmission member 20 and arranging the accelerator arm 40 in the direction of pulling the pressing arm 60,
When the driver depresses the accelerator arm 40 beyond the range of the normal depressing angle and the pressing arm 60 pulled by the driver depresses the transmission member 20, it resists the urging force that pulls both

arms

40, 60 in the proximity direction. It is characterized by giving resistance to the driver's feet.

According to the ninth aspect of the present invention, in the accelerator pedal malfunction canceling apparatus, the pedal side arm mechanism 50 of the accelerator arm 40 is applied with a biasing force in a direction opposite to the stepping direction so that the pedal exceeds the normal stepping angle. When the connection between the side arm mechanism 50 and the throttle valve side arm mechanism 47 is released and the connection to the throttle valve is released, the pedal side arm mechanism 50 is immediately stopped by stopping the depression of the pedal side arm mechanism 50. And the throttle valve side arm mechanism 47 are restored to enable normal accelerator operation.

According to the accelerator pedal malfunction elimination apparatus of the present invention having the above configuration, when the depression angle of the accelerator arm 40 exceeds the normal depression range, the brake arm 10 is swung in the depression direction together with the accelerator arm 40 via the transmission member 20. When the brake is applied and the accelerator arm 40 is further depressed, the connection of the accelerator arm 40 to the throttle valve is released and the accelerator is returned. Therefore, if the accelerator is depressed at a stroke to perform a downshift by kickdown, there is a surplus momentum. Even if you step on the accelerator too much, the brake is first depressed. In this case, the resistance to the sole when stepping on is clearly different between the accelerator and the brake, so the driver may notice that the stepping is too much at that stage and step on to the release position of the connection to the throttle valve at the next stage. Is prevented. On the other hand, since the accelerator is fully depressed at this stage, the vehicle speed does not decrease even if the brake is depressed, and the kickdown operation for acceleration is not hindered.

In the accelerator pedal malfunction elimination device of the present invention, when the depression angle of the accelerator arm 40 exceeds the normal depression range, the brake arm 10 is swung in the depression direction together with the accelerator arm 40 via the transmission member 20 to apply the brake. . In other words, the accelerator requires a step allowance for operating the brake in addition to the step allowance for the original accelerator operation. Therefore, there arises a problem that the positional relationship between the brake pedal and the accelerator pedal with respect to the vehicle body is different from that of a normal automobile.

The invention described in claim 4 was created for the purpose of solving the above-mentioned problems. That is, according to the present invention, the stepping angle of the accelerator arm 40 exceeds the normal range, the means for prohibiting the swing of the transmission member 20 is released, and the transmission member pressing portion of the accelerator arm 40 pushes the pressed portion of the transmission member for transmission. When the members are swung simultaneously, a brake arm pressing portion 90 that swings the brake arm 10 by a larger amount than the swinging amount of the transmission member is provided on the transmission member by the front end of the pressing portion moving forward from the transmission member. Features. As a result, the stepping amount of the accelerator for operating the brake can be made smaller than the actual stepping amount of the brake, and the positional relationship between the brake pedal and the accelerator pedal with respect to the vehicle body can be made natural.

According to the fifth aspect of the present invention, when the transmission member moves forward due to the swinging of the transmission member, the forward end swings in the downward direction by traveling on the traveling surface 75 having a height difference provided at the lower end of the stopper rod 70. The actuating lever 92 that pivots is pivotally attached to the transmission member 20, and the rear side of the pressing rod 94 that advances and retreats forward and backward of the transmitting member is pivoted above the actuating lever, whereby the transmitting member pressing portion is pressed against the transmitting member. When the transmission member is simultaneously swung by pushing, a brake arm pressing portion 90 that rocks the brake arm 10 by a larger amount than the swinging amount of the transmission member by advancing the pressing tip of the pressing rod forward of the transmission member; Therefore, the stepping amount of the accelerator for operating the brake with an extremely simple configuration can be made smaller than the stepping amount of the actual brake.

According to the eighth aspect of the invention, instead of directly pressing the transmission member 20 in the brake operating direction with the accelerator arm 40, the transmission is performed with the pressing arm 60 fixed to the accelerator arm with a biasing force in the proximity direction so as to be freely contacted and separated. Since the member is pressed and the accelerator arm is arranged in the direction of pulling the pressing arm 60, the driver steps on the accelerator arm 40 beyond the range of the normal stepping angle, and the pressing arm 60 pulled thereby pulls the transmission member 20 When pressing, a resistance force against the urging force that pulls both

arms

40 and 60 in the proximity direction is applied to the sole of the driver. As a result, the stepping allowance is generated from the stage where the driver depresses the accelerator beyond the range of the normal depression angle until the distance between the

arms

40 and 60 is increased until the brake is actually depressed. If the driver who feels the vehicle does not depress further, the brake is prevented from being depressed, and the kickdown operation for the purpose of acceleration is prevented more reliably.

According to the ninth aspect of the invention, since the urging force in the direction opposite to the stepping direction is applied to the pedal side arm mechanism 50 of the accelerator arm 40, the pedal side arm mechanism 50 and the throttle valve side exceed the normal stepping angle. When the connection to the arm mechanism 47 is released and the connection to the throttle valve is released, the pedal side arm mechanism 50 and the throttle valve side arm mechanism 47 are immediately Thus, the normal accelerator operation is enabled and normal operation is possible.

The accelerator pedal malfunction elimination device of the present invention activates the brake pedal by depressing the accelerator pedal or releases the connection to the throttle valve according to the depression angle of the accelerator pedal. Therefore, in the accelerator pedal malfunction elimination device of the present invention, in addition to the accelerator arm 40 that swings when the accelerator pedal AP is depressed and the brake arm 10 that swings when the brake pedal BP is depressed, A transmission member 20 is provided for cooperating both in accordance with the depression angle.

In the above, the depression angle of the accelerator pedal that triggers the operation of the brake pedal and the disconnection of the throttle valve exceeds the angle that the driver depresses in normal driving when the driver makes a mistake in depressing the brake and accelerator. The angle of the specified area is assumed. However, if the driver cannot sense the area, there is a risk that normal driving will be hindered. As described above, in the accelerator pedal malfunction elimination device of the present invention, since the brake is first depressed, the driver notices excessive depression due to the feeling of the sole at that stage, but in this embodiment, further constant resistance force is applied. By providing the given step allowance, the driver can more reliably detect it with the sole of the foot, and the brake is not immediately depressed.

With the above in mind, a specific embodiment of the accelerator pedal malfunction elimination apparatus of the present invention will be described below with reference to the accompanying drawings.

1 to 3 are perspective views for explaining members of the accelerator pedal malfunction elimination apparatus of the present invention. The brake arm 10 having the brake pedal BP at one end swings with respect to the vehicle body. In this embodiment, the brake arm 10 is fixed on the brake arm 100 already provided in the automobile. FIG. 3 shows this state, and the both are integrated by holding the brake arm 100 already provided in the automobile by the holder 11 protruding from the brake arm 10. In this case, the brake arm 10 of the present invention swings around the axis 101 of the brake arm 100 already installed in the automobile. In other figures, the illustration of the brake key pedal BP1 of the brake arm 100 already provided in the automobile is omitted.

The above configuration is based on the reason that the existing brake arm cannot be removed in accordance with the safety standard of the automobile. Of course, the brake arm 10 according to the present invention may be directly provided in the automobile if it meets the safety standard. is there.

The transmission member 20 is a member that starts to swing according to the depression angle of the accelerator pedal and transmits the swing to the brake arm 10, but is pivoted by the pivot 12 via the transmission member arm 20 </ b> A extending upward. It is provided so as to be swingable with respect to the brake arm. In this case, when the transmission member 20 swings in the stepping direction of the brake arm 10, the rear surface serving as the brake arm pressing portion pushes the overhang 13 serving as the pressed portion of the brake arm 10, and the brake arm is attached thereto. The shaft 101 of the brake arm 100 already installed in the automobile is swung around the pivot. Therefore, when the brake arm 10 is swung in the stepping direction, the swing is not transmitted to the transmission member 20.

The accelerator arm 40 is pivotally arranged with respect to the transmission member 20 with a pivot 61. The accelerator arm 40 pushes the transmission member 20 and swings it when it is depressed beyond the depression angle in normal driving, that is, when the driver makes a mistake in depressing the brake and the accelerator and depressing the brake intentionally.

On the other hand, if the transmission member 20 to which the accelerator arm 40 is pivotally attached is not fixed to the vehicle body within the stepping range in the normal operation, there is a possibility that the accelerator arm may swing as the accelerator arm swings. Therefore, in this embodiment, the stopper rod 70 whose one end is in contact with the wall surface S of the vehicle body is slidably fitted to the transmission member 20, and the sliding of the stopper rod 70 is restricted to the transmission member 20. A lock member 41 for fixing the stopper rod 70 is provided, and the lock member 41 is configured to be unlocked when the depression angle of the accelerator arm 40 exceeds a normal range. Thus, within the normal depression angle of the accelerator arm 40, one end of the stopper rod 70 that cooperates with the transmission member 20 by the lock member 41 comes into contact with the wall surface S of the vehicle body, and the swinging of the transmission member 20 is prohibited. Therefore, when the accelerator arm 40 swings with respect to the transmission member 20 (as shown in FIGS. 1, 2, 4, and 6) and the depression angle of the accelerator arm 40 exceeds the normal range, it is detected and the lock member 41 The transmission member 20 that is unlocked and free from the stopper rod 70 is pressed by the accelerator arm 40 and swings together with the accelerator arm 40 (states of FIGS. 7, 8, and 9).

The stopper rod 70 is formed in a rectangular shaft shape that is inserted into and slides in the holding portion 21 penetrating in the entire length direction of the transmission member 20, and an engagement hole 71 described later is formed on the middle upper surface from the middle. A running surface 72, which will be described later, is recessed on the upper surface of the wire, and is urged toward the back surface of the transmission member by a tension coil spring 73.

The lock member 41 is constituted by a lock lever 43 pivotally attached to the transmission member 20 in this embodiment. The lock lever engages and engages with an engagement hole 71 provided in a stopper rod 70 slidably fitted to the transmission member 20 at one end of the engagement portion 43 </ b> A. It is pressed by contact and separation of the abutting protrusion 42 provided, and is biased by the torsion coil spring 44 so that the engaging portion at one end is directed toward the stopper rod.

The lock lever 43 has one end pressed by pressing the abutting portion 43B at the other end by the abutting projection 42 protruding in front of the accelerator arm when the depression angle of the accelerator arm 40 exceeds the normal range. The operating position is set so that the engaging portion 43A swings in a seesaw shape and disengages from the engaging hole 71 provided in the stopper rod 70.

4 to 8 are diagrams showing the operation of the above configuration. In FIG. 7, when the engaging portion 43A is disengaged from the engaging hole 71 provided in the stopper rod 70 when the depression angle of the accelerator arm 40 exceeds the normal range, the lock by the lock member 41 is released, and the transmission member 20 is It becomes free with respect to the stopper rod 70. As a result, the transmission member 20 is pressed by the accelerator arm 40 and swings together with the accelerator arm 40, and the rear surface of the transmission member 20 pushes the overhang 13 of the brake arm 10 so that the brake arm is already installed in the vehicle to which the brake arm is attached. The brake is operated by swinging the shaft 101 of the 100 as a pivot. In the above case, the end of the stopper rod 70 that is in contact with the wall surface S of the vehicle body swings upward together with the transmission member 20, so that the movement is smoothed by providing the wheel 74 at the end. Yes.

In the above state, the brake operates but the accelerator is not released, so the speed of the car does not decrease. As a result, it is possible to prevent the accelerator from being immediately released when the accelerator depression angle exceeds the normal range by mistake during kickdown.

FIGS. 13 to 14 are diagrams showing different embodiments of the mechanism by which the transmission member 20 presses the brake arm 10. In the above description, the transmission member 20 is pressed by the accelerator arm 40 and swings together with the accelerator arm 40, and the back surface pushes the overhang 13 of the brake arm 10 to swing the brake arm. Therefore, the swing amount of the accelerator arm 40 and the swing amount of the brake arm 10 are equal. However, as described above, the accelerator requires a step for operating the brake in addition to the step for the original accelerator operation. Therefore, there arises a problem that the positional relationship between the brake pedal and the accelerator pedal with respect to the vehicle body is different from that of a normal automobile.

Therefore, in this embodiment, the stepping angle of the accelerator arm 40 exceeds the normal range, the means for prohibiting the swing of the transmission member 20 is released, and the transmission member pressing portion of the accelerator arm 40 pushes the pressed portion of the transmission member. When the transmission member is simultaneously swung, a brake arm pressing portion 90 that swings the brake arm 10 by an amount larger than the swing amount of the transmission member is provided on the transmission member by the front end of the pressing member moving forward from the transmission member. Yes.

In the figure, reference numeral 92 denotes an operating lever of the brake arm pressing portion 90. The actuating lever 92 has an inverted T-shape consisting of a base and a rising edge, and the rear end of the base is pivotally attached to the transmission member 20 by a pivot 91 so that the front end of the base swings up and down and the upper end of the rising edge swings back and forth To do. Reference numeral 94 in the figure denotes a pressing rod that moves forward and backward of the transmission member 20 and pushes the overhang 13 of the brake arm 10. The pressing rod 94 is moved back and forth in accordance with the swing of the operating lever by pivotally attaching the rear end thereof to the upper end of the rising side of the operating lever 92 by the pivot 93.

A traveling portion 95 for traveling on a traveling surface 75 provided at the lower end of the stopper rod 70 when the transmission member 20 is swung is provided at the bottom end of the operating lever 92. Although the wheel is employ | adopted here as the said traveling part 95, of course, it is not restricted to a wheel. The travel surface 75 is provided with a height difference that increases in height via a slope 75A at the start end. Therefore, when the transmission member pressing portion of the accelerator pedal pushes the pressed portion of the transmission member and simultaneously swings the transmission member, the traveling portion 95 at the tip of the bottom side of the operating lever 92 that is pivotally attached thereto moves the stopper member 70. The travel lever 75 swings counterclockwise by traveling on the traveling surface 75 provided at the lower end and climbing the slope 75A at the starting end of the traveling surface, and the pressing rod 94 pivotally attached to the upper end of the rising side moves forward. Then, the overhang 13 of the brake arm 10 is pushed.

The above is the description of the configuration for operating the brake pedal by depressing the accelerator pedal. Hereinafter, the configuration for releasing the connection to the throttle valve will be described below.

In this configuration, in this embodiment, the accelerator arm 40 is divided into a throttle valve side arm mechanism 47 on the connection side to the throttle valve and a pedal side arm mechanism 50 on the connection side to the accelerator pedal, and the connection for connecting both arm pieces is provided. A member 53 is provided. In this case, an urging force in a direction opposite to the stepping direction is applied to the pedal arm mechanism 50 by a torsion coil spring (not shown). Thereby, when the connection between the pedal side arm mechanism 50 and the throttle valve side arm mechanism 47 is released beyond the normal stepping angle and the connection to the throttle valve is released, the pedal side arm mechanism 50 is depressed. By stopping the operation, the connection between the pedal side arm mechanism 50 and the throttle valve side arm mechanism 47 is immediately restored, and the normal accelerator operation is enabled and the normal operation is possible.

The connection member 53 operates when the brake pedal is operated when the depression of the accelerator arm 40 exceeds the normal depression angle, and when the depression is further depressed, the connection with the throttle valve side arm mechanism 47 is released. This is for releasing the connection to the throttle valve. This connecting member 53 is provided with an engaging arm 55 at the right end of a pivot 54 arranged on a pressing arm 60 (details will be described later) cooperating with the accelerator arm 40 and a traveling arm 56 at the left end. An engaging portion 55A for engaging with an engaging portion 47A provided in the throttle valve side arm mechanism 47 is provided at the tip, and an upper surface of a stopper rod 70 that slides against the accelerator arm 40 is provided at the tip of the traveling arm 56. A traveling unit 57 for traveling on the traveling surface 72 is provided. Although the wheel is adopted here as the traveling portion, it is needless to say that the traveling portion is not limited to the wheel.

On the other hand, the traveling surface 72 traveling on the traveling portion 57 is recessed in the shape of a groove or a notch from the front to the middle of the upper surface of the stopper rod 70, and forms a slope that follows the upper surface of the stopper rod at the end thereof. There is a height difference.

FIG. 10 to FIG. 11 are diagrams showing the operation of the above configuration. In FIG. 10, when the depression angle of the accelerator arm exceeds the normal range, the brake is first actuated, and when the driver further depresses the accelerator and the transmission member 20 moves with respect to the stopper rod 70, the stopper rod is moved accordingly. The traveling portion 57 of the traveling arm 56 of the connecting member 53 traveling on the upper traveling surface 72 of the connecting member 53 is lifted by climbing the end slope of the traveling surface. As a result, the connecting member 53 swings in the direction of releasing the connection with the throttle valve side arm mechanism 47, the throttle valve side arm mechanism is disconnected from the pedal side arm mechanism 50, and the throttle wire is biased by the urging force of the accelerator wire W. The engine is pulled back to the off side and the engine is idling. In this embodiment, an automobile in which the throttle valve is controlled using an accelerator arm and an accelerator wire is taken as an example. However, an automobile in which the angle of the rotation axis of the accelerator arm is detected by a sensor and the engine is electronically controlled may be used. Of course.

In the above state, the accelerator is released and the brake is activated by depressing the accelerator. As a result, the speed of the vehicle can be controlled by adjusting the accelerator.

With the above two characteristic configurations, the accelerator pedal malfunction elimination device according to the present invention operates the brake pedal when the driver makes a mistake in stepping on the brake and the accelerator and exceeds the angle of depression in normal driving. Or disconnect. Therefore, when the driver makes a mistake in stepping on the brake and the accelerator, the vehicle can be stopped appropriately without running out of control.

15 to 16 are views showing different embodiments of the throttle valve side arm mechanism 47 described above. In the above description, the throttle valve side arm mechanism 47 hooks the accelerator wire W to the end of the arm extending above the pivotally attached portion 61, and operates the accelerator wire by swinging it. Therefore, it is necessary to secure an amount of movement of the arm end due to the swing enough to operate the accelerator wire, inevitably the arm length becomes long, and an upper space for accommodating the arm is necessary.

However, the above upper space may not be secured depending on the type of car. Therefore, in this embodiment, the throttle valve side arm mechanism is divided into an engagement side arm for engaging with the engagement arm 55 of the connection member 53 and a engagement side arm for engaging with the accelerator wire W. These are arranged in the front-rear direction, and both are connected by a rod to shorten the vertical dimension.

In the figure, reference numeral 82 denotes the throttle valve side arm mechanism. In the figure, reference numeral 89 denotes an engagement side arm, 83 denotes a latching side arm, and 86 denotes a rod. The engagement side arm 89 has one side as an engagement portion 89A for engaging with the engagement portion 55A of the engagement arm 55 of the connection member 53, and a rod at the lower end of the pivotal attachment portion 88 with the transmission member 20. A pivot attachment portion 87 with 86 is provided. The latching arm 83 has an upper end of the pivoting portion 84 with the transmission member 20 as a latching location with the accelerator wire W, and a pivoting portion 85 with the rod 86 at the lower end. Therefore, the engagement side arm 89 and the latching side arm 83 swing through the rod 86, and the pivot side 88 between the engagement side arm 89 and the transmission member 20 and the pivot point 87 between the rod 86 and the pivot 86. By setting the dimension between the pivoting portion 84 of the latching arm and the pivoting portion 85 of the rod to be shorter than the dimension, the swinging amount of the latching arm can be made smaller than the swinging amount of the engagement side arm. Can be big. As a result, even if the vertical dimension is shortened, the movement amount of the arm end due to the swinging of the latching side arm 83 can be ensured enough to operate the accelerator wire W.

In the accelerator pedal malfunction elimination device of the present invention, since the brake is first depressed, the driver notices excessive depression due to the feeling of the soles at that stage. By providing this, the following configuration is prepared so that the driver can more reliably detect it with the sole of the foot and the brake is not immediately depressed.

Therefore, in this embodiment, the transmission member 20 is pressed by the pressing arm 60 that cooperates with the accelerator arm, instead of directly pressing the transmission member 20 by the accelerator arm 40 in the operating direction of the brake. That is, the accelerator arm 40 provided with the contact protrusion 42 that presses the lock lever 43 and the pressing arm 60 are pivotally fixed to the transmission member 20 with a common pivot 61 and the

arms

40 and 60 are connected to each other. By fixing the urging force in the proximity direction so as to be freely movable, the pressing arm 60 is used as a pressing portion to the transmission member 20, and the accelerator arm 40 is disposed in a direction in which the pressing arm 60 is pulled, so that the driver can operate the accelerator. When the arm 40 is stepped out beyond the range of the normal stepping angle, and the pressing arm 60 pulled by the arm 40 presses the transmission member 20, the stepping allowance until the brake is stepped on by opening both the

arms

40, 60 is reduced. At the same time, a resistance force against the urging force attracted in the proximity direction is applied to the sole of the driver.

In the figure, reference numeral 51 denotes an overhang for superposition provided on the pedal side arm mechanism 50 of the accelerator arm 40. The pressing arm 60 is superposed on the above-described superposition overhang 51 and is fixed by a bolt / nut 62 penetrating both. However, the compression coil spring 63 is interposed between the nut and the overhang for superposition so that both arms are moved in the proximity direction. Giving the urging power to attract.

FIG. 7 is a diagram showing the operation of the above configuration. When the engaging portion 43A is disengaged from the engagement hole 71 provided in the stopper rod 70 when the stepping angle of the accelerator arm 40 exceeds the normal range, the lock by the lock member 41 is released, and the transmission member 20 is stopped by the stopper rod 70. The transmission member 20 is pressed by the accelerator arm 40 and tries to swing together with the accelerator arm 40. In this case, it is the pressing arm 60 superposed on the accelerator arm that presses the accelerator arm, and this pressing arm is pulled by the accelerator arm, but in an initial state in which the transmission member 20 to be pressed is about to swing. Since the transmission member 20 is prohibited from swinging by the stopper rod 70, first, the accelerator arm is swung against the urging force in the pulling direction by the compression coil spring 63, and both

arms

40 and 60 are opened. A step allowance until the brake is depressed is generated, and the driver can sense the resistance with the sole of the foot.

In the initial stage of operating the brake arm 10 by the accelerator arm 40, a warning buzzer may be sounded by the switch 80 operated thereby to notify the driver.

¡This accelerator pedal malfunction elimination device does not interfere with normal driving and can be realized with a simple structure, thus contributing to the prevention of automobile accidents.
