Description

The present invention relates to, for example, a pedal erroneous operation prevention device that prevents a driver of an automobile from mistakenly stepping on a brake pedal and an accelerator pedal.

For example, when driving, stopping, starting, etc., the driver mistakenly presses the accelerator pedal for the brake pedal, which often leads to a serious accident. In an automatic vehicle, it is common for the driver to operate the accelerator pedal and the brake pedal with his right foot. That is, in order to switch the pedal operation, the driver operates the pedal by changing the tilt angle, position, and the like of the foot that operates the pedal. However, when the driver panics, it becomes impossible to determine which pedal is depressed, and it is said that the accelerator pedal is depressed once strongly by mistake for the brake pedal. Conventionally, there are various techniques for preventing such erroneous operation of the pedal, and for example, there is one described in Patent Document 1.

Patent Document 1 discloses that the disturber bar is fixedly arranged on the vehicle interior floor between the accelerator pedal and the brake pedal. Since the disturber bar separates the accelerator pedal and the brake pedal, the driver's foot cannot be moved to the left or right. Therefore, the driver cannot operate the accelerator pedal and the brake pedal with one foot, which prevents erroneous pedal operation.

Japanese Unexamined Patent Publication No. 2014-21546

However, the technique described in Patent Document 1 is to partition the accelerator pedal and the brake pedal with a disturber bar, which is fixed to the floor inside the vehicle. Therefore, when the driver gets on and off the vehicle, the driver has to take off and take off the seat across the disturber bar, which causes trouble for the driver. In addition, if the driver's feet hit the disturber bar when the driver gets on and off, the disturber bar may be damaged or the driver may be injured.

Therefore, the present invention is intended to provide a pedal erroneous operation prevention device that is easy for a driver to get on and off a vehicle and can partition between an accelerator pedal and a brake pedal according to the driver's vehicle operation. be.

The pedal erroneous operation prevention device of the present invention touches a first position between the accelerator pedal and the brake pedal, which indicates a position for separating the operation of the accelerator pedal and the operation of the brake pedal, and a driver getting on and off. Turns on / off the pedal operation separation mechanism unit having a blocking member that moves between the second position indicating no position, the drive unit that transmits the driving force to the pedal operation separation mechanism unit, and the vehicle-mounted power supply. A drive control unit that drives and controls the drive unit in response to the operation of the first switch is provided, and the blocking member moves from the second position to the first position by the ON operation of the first switch. The blocking member is moved from the first position to the second position by the OFF operation of the switch 1.

According to the present invention, it is easy for the driver to get on and off the vehicle, and the accelerator pedal and the brake pedal can be partitioned according to the driver's operation of the vehicle.

(A) First Embodiment The first embodiment of the pedal erroneous operation prevention device according to the present invention will be described below with reference to the drawings.

(A-1) Technical Concept of Pedal Misoperation Prevention Device FIG. 1 is a configuration diagram showing a configuration of a pedal erroneous operation prevention device according to the first embodiment.

In FIG. 1, the pedal erroneous operation prevention device 1 according to the first embodiment includes a start switch 21 for turning on / off the power of the vehicle engine or the electric system, and a switch 22 for manually switching the operation of the pedal erroneous operation prevention device 1. It has a control unit 20 connected to the start switch 21 and the switch 22, a drive unit 30 that operates by driving control of the control unit 20, and a pedal operation separation mechanism unit 10 that operates by receiving a driving force from the drive unit 30.

The pedal erroneous operation prevention device 1 prevents the driver from operating both the accelerator pedal AP and the brake pedal BP with one foot when the start switch 21 is operated by the driver and the vehicle-mounted power supply is switched from OFF to ON. Therefore, the blocking member 11 of the pedal operation separation mechanism unit 10 receives a driving force from the drive unit 30 and moves to a position where the accelerator pedal AP and the brake pedal BP are separated from each other and stops. On the other hand, in the pedal erroneous operation prevention device 1, when the vehicle power is switched from ON to OFF, the blocking member 11 located between the accelerator pedal AP and the brake pedal BP moves to the original position (release position) and shuts off. To cancel.

In this way, when the driver turns on the start switch 21, the blocking member 11 moves to a separated position that shuts off between the accelerator pedal AP and the brake pedal BP, so that the driver can use one foot to cut off the accelerator pedal. Both AP and brake pedal BP cannot be operated. Then, the driver can be made aware that the accelerator pedal AP is operated with the right foot and the brake pedal BP is operated with the left foot. By making the driver aware that the brake pedal BP is stepped on with the left foot, even if the driver panics, it is possible to prevent the accelerator pedal AP from being stepped on by mistake for the brake pedal BP.

On the other hand, when the power supply in the vehicle is off, the blocking member 11 is located at the release position, so that the blocking member 11 can be prevented from getting in the way of the driver. In other words, it is possible to get on and off smoothly as before. Further, damage to the blocking member 11 and injury to the driver can be prevented.

Here, the separated position (hereinafter, also referred to as "first position") is the accelerator pedal AP and the brake so that the driver cannot operate the accelerator pedal AP and the brake pedal BP with one foot. It is a position to separate (block) from the pedal BP. The separation position is a position in the space between the accelerator pedal AP and the brake pedal BP, and the driver is aware that the driver cannot move his / her foot or cannot move his / her foot due to the pedal operation. Can be made to.

Further, the release position (hereinafter, also referred to as "second position") is a position where the separation (blocking) of the accelerator pedal AP and the brake pedal BP is released, and is an obstacle to the driver who performs the driving operation. It is a position that does not become. In the case of the first embodiment described later, the position where the blocking member 11 is housed in the housing of the main body 13 will be described as the release position.

(A-2) Pedal erroneous operation prevention device of the first embodiment [control unit, start switch, switch]
The control unit 20 is connected to the start switch 21 and the switch 22, and drives and controls the drive unit 30 based on an electric signal from the start switch 21 or the switch 22 operated by the driver.

The control unit 20 mainly includes a switching unit 201 that switches the connection between the start switch 21 and the switch 22, and a drive control unit 202 that drives and controls the drive unit 30 based on an electric signal from the switching unit 201. The control unit 20 can be composed of, for example, circuit elements such as transistors and resistors, and electronic components such as a microcomputer.

The start switch 21 is an ignition key, a push-type start button, or the like that turns on or off the power of the starter motor that starts the engine of the vehicle, and is provided on the dashboard 8, for example. The start switch 21 can turn on or off the power of the starter motor and turn on or off only the accessory (ACC) power supply of the electric system such as an air conditioner, but either the power supply of the starter motor or the ACC power supply can be used. The pedal erroneous operation prevention device 1 may be operated by being turned ON / OFF.

When the start switch 21 is turned on by the driver, the power supply of the starter motor for starting the engine and the ACC power supply are turned on, and the start ON signal is supplied to the control unit 20, the control unit 20 is operated by the pedal operation separation mechanism unit 10. The drive unit 30 is driven so as to move the blocking member 11 of the above to the separation position. On the other hand, when the start switch 21 is turned off and the start OFF signal is supplied to the control unit 20, the control unit 20 drives the blocking member 11 located at the separated position to move to the original position. Drive 30. Here, the electric signal supplied to the control unit 20 when the start switch 21 is turned on is called a start ON signal, and the electric signal supplied to the control unit 20 when the start switch 21 is turned off is called a start OFF signal.

The switch 22 is a switch provided separately from the start switch 21, and is a switch that turns on or off the operation of the pedal erroneous operation prevention device 1. The switch 22 is provided on the dashboard 8, for example. Depending on the driver, it may be desired to operate the pedal erroneous operation prevention device 1 other than by operating the start switch 21 (for example, turning on / off the power of the starter motor or the like). Therefore, in order to allow the blocking member 11 to be moved to the separated position or the blocking member 11 to be returned to the release position according to the driver's preference, in this embodiment, the pedal is manually prevented from being erroneously operated separately from the start switch 21. A switch 22 for operating the device 1 is provided. By the ON / OFF operation of the switch 22, an electric signal is supplied from the switch 22 to the control unit 20, and the control unit 20 drives and controls the drive unit 30.

For example, the control unit 20 can be operated in either a first operation mode in which only the start switch 21 is turned on / off, or a second operation mode in which both the start switch 21 and the switch 22 are turned on / off. The drive may be controlled. Further, the control unit 20 is provided with a third operation mode in which the pedal erroneous operation prevention device 1 cannot be operated by the ON / OFF operation of the start switch 21, but is operated by the ON / OFF operation of only the switch 22. You may. The operation mode of the control unit 20 may be set / changed by the driver by a physical switch, software processing, or the like.

The first operation mode is drive-controlled based on the ON / OFF operation of only the start switch 21. In this case, the control unit 20 does not switch the connection to the switch 22, and the control unit 20 drives and controls the drive unit 30 by the start ON signal or the start OFF signal from the start switch 21. Therefore, for example, the shutoff member 11 moves the accelerator pedal AP and the brake pedal BP to the shutoff state position or the shutoff release state position according to the start or end of the engine or the like, so that safe pedal operation can be realized.

In the second operation mode, the control unit 20 drives and controls based on the signals from both the start switch 21 and the switch 22. More specifically, when the start ON signal is supplied from the start switch 21 to the control unit 20, the control unit 20 drives and controls the drive unit 30 so as to move the blocking member 11 to the separation position. On the other hand, when the start OFF signal is supplied from the start switch 21 to the control unit 20, the control unit 20 drives and controls the drive unit 30 so as to move the blocking member 11 to the original position. This is the basic drive control of the control unit 20, but when the OFF signal is supplied from the switch 22 to the control unit 20 after the start ON signal is supplied, the control unit 20 moves the cutoff member 11 to the release position. Drive control. Further, when the ON signal is supplied from the switch 22 to the control unit 20 when the cutoff member 11 is in the release position, the control unit 20 moves the cutoff member 11 to the separation position in the drive unit 30. Is driven and controlled. By doing so, for example, the blocking member 11 can be moved according to the start or end of the engine or the like, and the blocking member 11 can be moved according to the driver's preference, so that the range of choices of the driver is widened. ..

The third operation mode is driven and controlled based on the ON / OFF operation of only the switch 22. In this case, the control unit 20 does not switch the connection to the start switch 21, and the control unit 20 drives and controls the drive unit 30 by the electric signal from the switch 22. In this case, the blocking member 11 cannot be moved by the ON / OFF operation of the start switch 21, but the blocking member 11 can be operated according to the driver's preference.

[Drive part]
The drive unit 30 transmits a driving force to the pedal operation separation mechanism unit 10 to drive the pedal operation separation mechanism unit 10 by the drive control of the control unit 20, and for example, a motor or the like can be applied. In this embodiment, the case where the drive unit 30 is mounted on the pedal operation separation mechanism unit 10 is illustrated, but if the pedal operation separation mechanism unit 10 can be operated, the outside of the pedal operation separation mechanism unit 10 is illustrated. It may be provided in.

[Pedal operation separation mechanism]
The pedal operation separation mechanism unit 10 includes a main body unit 13, a rotating shaft unit 14 that receives a driving force from the driving unit 30, and a blocking member 11 that rotates about the rotating shaft unit 14. In the first embodiment, the case where the blocking member 11 rotates about the rotation shaft portion 14 is illustrated, but it can be moved between the separated position where the accelerator pedal AP and the brake pedal BP are separated and the original position. If, then it is not limited to this. A modified example of the pedal operation separation mechanism unit 10 will be described later.

FIG. 2 is a plan view of the pedal operation separation mechanism unit 10 according to the first embodiment. 3 and 4 are layout drawings showing an arrangement example of the pedal operation separation mechanism portion 10 according to the first embodiment.

As shown in FIGS. 3 and 4, the pedal operation separation mechanism portion 10 is arranged on the vehicle interior floor 7 between the accelerator pedal AP and the brake pedal BP. The pedal operation separation mechanism unit 10 can also be provided between the accelerator pedal AP and the brake pedal BP of the driver's seat 5 of an existing automobile. At this time, one end 111 of the blocking member 11 (that is, the end facing the other end 112 connected to the rotating shaft 14), which rotates about the rotating shaft 14, is the driver's seat 5. The pedal operation separation mechanism portion 10 is arranged so as to be on the foot side of the driver seated in the vehicle. As a result, the movement of the foot of the driver who operates the pedal can be regulated, and the driver can be made aware of it, so that erroneous operation of the pedal can be effectively prevented.

Generally, the brake pedal BP is often arranged at a position corresponding to the position of the central portion of the handle 4, but as illustrated in FIG. 4, for example, the length of the brake pedal arm portion 62 and the extending direction ( The installation direction) and the like may be improved so that the brake pedal BP is arranged on the left side of the position of the central portion of the handle 4. By arranging the position of the brake pedal BP on the left side in this way, the distance between the brake pedal BP and the accelerator pedal AP becomes larger than before, so that the space for arranging the pedal operation separation mechanism portion 10 is wide. Become. Further, since the brake pedal BP is arranged near the driver's left foot, the driver can easily operate the brake pedal BP with the left foot. Further, since the distance between the brake pedal BP and the accelerator pedal AP is increased, it is possible to prevent the driver from making a mistake in pedaling. In any case, the pedal operation separation mechanism unit 10 is arranged between the accelerator pedal AP and the brake pedal BP.

The main body portion 13 is a frame member that houses the blocking member 11, the rotating shaft portion 14, and the driving portion 30. In this embodiment, the case where the drive unit 30 is housed in the main body 13 is illustrated, but if the drive unit 30 can supply the driving force, the drive unit 30 is provided outside the main body 13. You may.

It is desirable that the size of the outer shape of the main body 13 is such that the driver does not touch the driver's feet when getting on and off. More specifically, for example, the length (height h in FIG. 1) of the main body 13 in the height direction (z-axis direction in FIG. 1) can be about 2 to 5 cm. Further, the length (distance length D1 in FIG. 2) of the main body 13 in the longitudinal direction (x-axis direction in FIGS. 1 and 2) can be about 20 to 50 cm. Further, the length in the width direction (y-axis direction in FIG. 2) of the main body 13 (the length in the longitudinal direction on the plane of the plane view of the main body 13; the distance length D2 in FIG. 2) is about 2 to 10 cm. Can be. The size of the outer shape of the main body 13 is not limited to these. The material of the main body 13 is preferably formed of a material having a certain degree of strength in consideration of being stepped on by the driver, and a part or all of the members of the main body 13 are made of, for example, metal, synthetic resin, or the like. It may be formed, or it may be formed by combining a metal member and a synthetic resin member.

As shown in FIG. 2, the upper surface portion 101 of the main body portion 13 has a substantially rectangular opening in order to allow the blocking member 11 to rotate in the vertical direction (the z-axis direction in FIG. 1 or the opposite direction). 102 is provided. The opening 102 is provided at a position corresponding to the position of the blocking member 11, and the size of the opening 102 (length in the longitudinal direction, length in the width direction) allows the blocking member 11 to rotate. , Slightly larger than the size of the blocking member 11 (length in the longitudinal direction, length in the width direction). FIG. 2 illustrates a case where the drive unit 30 is provided on the end 112 side of the blocking member 11 in the housing of the main body 13, and here, the main body is above the drive unit 30. The upper surface portion 101 of 13 is provided.

The main body portion 13 may have a fixing portion (not shown) in order to prevent the pedal operation separation mechanism portion 10 from moving on the vehicle interior floor 7 due to the traveling of the vehicle. The fixing portion may be a member that can be fixed to the vehicle interior floor 7 with bolts, nuts, or the like, or is fixed to a mat laid on the vehicle interior floor 7 of the driver's seat, such as a hook-and-loop fastener. It may be a thing.

The rotating shaft portion 14 rotates by receiving a driving force from the driving portion 30, and rotates the blocking member 11.

The blocking member 11 is a rod-shaped member that rotates upward or downward with the rotating shaft portion 14 as an axis by rotating the rotating shaft portion 14 in response to a driving force from the driving unit 30. The cross-sectional shape of the blocking member 11 is not particularly limited, and may be circular, quadrangular, elliptical, polygonal, or the like. It is possible that the blocking member 11 may hit the driver's foot or the like, which may damage the blocking member 11. Therefore, it is desirable that the blocking member 11 is made of a material having a certain degree of strength, for example, a light metal. It may be formed of a member, or may be formed of, for example, a synthetic resin.

For example, when the start switch 21 is turned on, the blocking member 11 rotates about the rotating shaft portion 14, and the end portion 111 of the blocking member 11 draws an arc and moves upward (in the z-axis direction in FIG. 1). Rise. The blocking member 11 maintains a predetermined angle and stops in an inclined state. In this embodiment, the position where the blocking member 11 is stopped while maintaining a predetermined angle is the separation position of the blocking member 11.

On the other hand, for example, when the start switch 21 is turned off, the blocking member 11 rotates about the rotating shaft portion 14, and the end portion 111 of the blocking member 11 draws an arc and moves downward (the z-axis direction in FIG. 1). It descends in the opposite direction of the above) and is stored in the main body 13. The position in which the blocking member 11 is housed in the main body 13 is the original position (release position).

The angle at which the blocking member 11 is maintained at the separated position is not particularly limited, but can be any angle of, for example, 20 to 45 degrees as long as the movement of the foot of the driver who operates the pedal can be regulated. .. By locating the blocking member 11 at a position where the accelerator pedal AP and the brake pedal BP are separated from each other, the driver can be made aware that the accelerator pedal AP and the brake pedal BP are operated by different feet. As a result, erroneous operation of the brake pedal BP and the accelerator pedal AP can be prevented.

On the other hand, at the release position, the driver who gets on and off can easily straddle the pedal operation separation mechanism portion 10 while the blocking member 11 is housed in the main body portion 13, and getting on and off is easy. Since it is possible to prevent the driver's foot from hitting the blocking member 11, damage to the blocking member 11 and injury to the driver can be avoided.

(A-3) Deformation Example of Pedal Operation Separation Mechanism The overall configuration of the pedal erroneous operation prevention device 1 can basically be the configuration described with reference to FIGS. 1 to 4, and the pedal operation separation mechanism can be used. With respect to 10, various modified embodiments can be applied as long as the operation of the accelerator pedal AP and the operation of the brake pedal BP can be separated.

In the following, an example of a modified embodiment of the pedal operation separation mechanism unit 10 will be illustrated with reference to FIGS. 5 and 6. The start switch 21, the switch 22, and the control unit 20 are not shown.

FIG. 5 is a configuration diagram showing the configuration of the pedal operation separation mechanism unit according to the modified embodiment. The pedal operation separation mechanism unit illustrated in FIG. 5 is referred to as "pedal operation separation mechanism unit 10A".

The pedal operation separation mechanism portion 10A has a support member 12 and a rotary shaft portion 15 in addition to the rotary shaft portion 14 and the blocking member 11 in the main body portion 13.

One end 121 of the support member 12 is connected to the rotating shaft portion 15 and is pivotally attached rotatably. On the other hand, regarding the connecting portion between the other end 122 of the support member 12 and the blocking member 11, the blocking member 11 is provided with a groove 17, and the other end 122 of the supporting member 12 is provided with the blocking member 11. A sliding piece 16 that slides in the groove 17 is provided.

Therefore, for example, when the start switch 21 is turned on, the rotating shaft portion 15 that receives the driving force from the driving portion 30 rotates, and the sliding piece 16 of the support member 12 slides in the groove portion 17 of the blocking member 11. While doing so, the other end 122 side of the support member 12 rotates in the upward direction (z-axis direction). Then, one end 111 of the blocking member 11 moves upward, and the blocking member 11 moves to the separation position and stops.

Here, the end portion 171 of the groove portion 17 in the blocking member 11 functions as a stopper for the sliding piece 16, and the end portion 171 of the groove portion 17 stops the sliding piece 16 sliding in the groove portion 17, and the blocking member 11 Is held in the separated position. Although not shown, the end portion 171 of the groove portion 17 may be provided with a fitting portion for fitting the sliding piece 16 of the blocking member 11 so that the blocking member 11 can be held at a separated position. good. By fitting the sliding piece 16 into the fitting portion of the end portion 171 of the groove portion 17, the support member 12 can strongly support the blocking member 11.

On the other hand, for example, when the start switch 21 is turned off, the rotating shaft portion 15 that receives the driving force from the driving portion 30 rotates, and the sliding piece 16 of the support member 12 slides in the groove portion 17 of the blocking member 11. While moving, the other end 122 side of the support member 12 rotates downward (in the direction opposite to the z-axis direction). Then, one end 111 of the blocking member 11 moves downward, and the blocking member 11 is housed in the main body 13 and returns to the original position.

6 (A) and 6 (B) are configuration diagrams showing the configuration of the pedal operation separation mechanism unit according to the modified embodiment.

The pedal operation separation mechanism unit 10A illustrated in FIGS. 6 (A) and 6 (B) basically has the same configuration as the pedal operation separation mechanism unit 10A illustrated in FIG. 5, but has an accelerator pedal AP and a brake. In order to ensure separation from the pedal BP and to ensure more attention to the driver, a case where the blocking member 11 is provided with the film portion 103 or the wire rod 104 will be illustrated.

Here, a case where the film portion 103 and the wire rod 104 are applied to the pedal operation separation mechanism portion 10A of FIG. 5 is illustrated, but the pedal operation separation mechanism portion without the support member 12 illustrated in FIG. 1 and the like is provided. It may be given to 10.

As shown in FIG. 6A, the blocking member 11 is provided with a film portion 103, and when the blocking member 11 rotates upward, the film portion 103 expands and the blocking member 11 moves downward. By rotating, the film portion 103 shrinks and is housed in the main body portion 13. The lower end side of the film portion 103 may be fixed to the main body portion 13. FIG. 6A illustrates a case where the film portion 103 is provided over the entire length of the blocking member 11, but if it is possible to reliably alert the driver, the blocking member 11 may be used. The film portion 103 may be provided only on a part of the total length. In that case, it is desirable, but not limited to, the film portion 103 to be provided on the one end 111 side of the blocking member 11 in consideration of directing the driver's consciousness. Further, for example, a cloth (woven fabric), a mesh-like cloth or the like can be applied to the film portion 103, and the material may be, for example, synthetic resin fiber, cotton, silk or the like.

As shown in FIG. 6B, one end of the wire rod 104 may be provided to one end portion 111 of the blocking member 11, and the lower end portion of the wire rod 104 may be fixed to the main body portion 13. Also in this case, the wire rod 104 is stretched by rotating the blocking member 11 upward, and the wire rod 104 is housed in the main body 13 by rotating the blocking member 11 downward. The wire rod 104 may be, for example, a metal wire rod, a synthetic resin wire rod, or the like. Further, the method of attaching the wire rod 104 is not limited to FIG. 6B as long as the driver's consciousness can be directed. The number of wire rods 104 may be two or more.

Separate the positions of the accelerator pedal and the brake pedal Move between the separated position and the original position. Therefore, when the driver drives the vehicle, the operation of the accelerator pedal and the brake pedal can be separated by the blocking member, and erroneous operation of the pedal can be prevented. On the other hand, when the driver gets on and off, the blocking member returns to a position where the driver does not get in the way, so that the driver can get on and off easily. Further, damage to the blocking member and injury to the driver can be prevented.

Further, in the first embodiment, by providing a switch different from the start switch, the blocking member can be manually operated according to the driver's preference.

Further, in the first embodiment, by applying the film portion or the wire rod to the blocking member, the operation separation between the accelerator pedal and the brake pedal can be ensured, and the driver can be more surely alerted. ..

(B) Second Embodiment Next, a second embodiment of the pedal erroneous operation prevention device of the present invention will be described in detail with reference to the drawings.

The pedal erroneous operation prevention device of the second embodiment can basically have the configuration described with reference to FIGS. 1 to 4 of the first embodiment. The difference from the first embodiment is the configuration of the pedal operation separation mechanism unit. Therefore, in the following, the configuration of the pedal operation separation mechanism unit of the second embodiment will be described with reference to the drawings. The description of the start switch 21, the switch 22, and the control unit 20 will be omitted.

Each of the blocking members 11B-1 and 11B-2 receives the driving force of the driving unit 30 and rises or falls in the direction perpendicular to the main body 13B (z-axis direction). The blocking members 11B-1 and 11B-2 are made of, for example, a metal member, a synthetic resin, or the like.

The state in which all the blocking members 11B-1 and 11B-2 are housed in the main body 13B is the release position of the blocking member 11. In the state where the plurality of blocking members 11B-1 and 11B-2 are housed (that is, the blocking member 11B is in the release position), the upper surface position of each blocking member 11B-1 and 11B-2 is the main body 13B. It is located at the same level as the position of the upper part of the housing, or slightly lower than the position of the upper part of the housing of the main body 13B.
