Description

TECHNICAL FIELD The present invention relates to a vehicle driving operation system, and more particularly to a vehicle driving operation system having a floor structure for pedal operation in consideration of safe driving.

(Prior Art) In a conventional floor structure of a driver's seat, a brake pedal and an accelerator pedal are arranged in parallel on the right side on a flat floor surface. Is much longer, the pedal operation is a large movement of the whole leg around the hip joint as a fulcrum, and it is inevitable that the footwork is performed while moving the heel position of the operating foot.

(Problems to be Solved by the Invention) However, in such a conventional driving operation system, since the motion of pedal operation is inevitably large for the entire leg, trouble occurs when quick and quick operation is required. It was easy to occur.

That is, since the heel position of the operating foot during driving is not fixed depending on each driver's individuality, an accident such as a pedal depression is likely to occur during a critical emergency. In particular, it has been reported that such accidents often occur in an automatic vehicle, because the operation rhythm is inherently difficult to obtain because it is operated by one foot. Accidents are particularly frequent when switching from clutch cars to automatic cars.

In addition, since there is not enough support or locking means for the foot during operation on a flat floor surface, when the driver's center of gravity moves forward due to the law of inertia during deceleration or locking, the accelerator pedal or If you put your weight on the brake pedal itself, or your foot becomes rigid in an emergency and you excessively step on it, sudden start, sudden braking or sudden stop will cause your own rear-end collision, rear-end rear-end collision, slip. This caused an accident and a runaway accident in the back direction.

Furthermore, since there is no support point for the foot, the balance of the driver's posture must be maintained by the arm with the handle, which causes a problem of easy fatigue.

Therefore, in view of such a problem, it is an object of the present invention to provide a safe vehicle operation system that allows quick pedal operation while supporting the user's weight with the operating foot even during pedal operation, and prevents erroneous pedal operation.

(Means for Solving the Problems) In order to achieve the above object, the present invention rotatably and rotatably supports a heel of a foot for a brake operation on a floor surface at a front facing position of a brake pedal provided on a front surface of a driver's seat. A heel support point is provided, and the brake pedal and the accelerator pedal are arranged on a concentric circle centering on the heel support point so that the brake pedal and the accelerator pedal can be operated while rotating the heel while the heel is placed on the heel support point. The car driving operation system was constructed.

In addition, the tread surface of the brake pedal is installed at substantially the same height as or lower than the tread surface of the accelerator pedal, and the brake stroke is long enough to allow the brake operation with the heel resting on the heel support point. It is preferable that

Further, a guide plate portion inclined downward is provided at an end edge of the step surface of the brake pedal on the accelerator pedal side, and an upper edge is provided at an end edge of the step surface of the brake pedal opposite to the guide plate portion. An extended stop plate portion may be provided.

The heel support point can be configured by providing a recess or a protrusion on the floor surface on which the heel of the operating foot is rotatably locked, and the heel protrusion is preferably attached via a bearing.

Still further, a magnet or a magnetic body is provided at the heel support point, and a magnetic body or a magnet is provided at the heel portion of footwear to be worn on the operating foot so that the operating foot heel can be easily locked at the heel support point. Is also good.

(Operation) According to the floor structure of the vehicle driver's seat and the vehicle operation system configured as described above, the heel is rotated about the heel support point while the heel of the operating foot is placed on the heel support point. While operating, the accelerator pedal and the brake pedal are operated. At this time, the driver's own weight can be applied to the heel of the operating foot while operating the pedal, so the posture balance of the driver can be maintained with both feet, and the motion of the pedal operation uses the conventional hip joint as the fulcrum. It is a small motion with the heel as a fulcrum, without making the entire leg large. Therefore, even when operating one leg of an automatic vehicle, the operation posture is stable, and the operation rhythm is easily taken and stabilized. In addition, even when decelerating or stopping, the weight of the driver's body accelerated will not be excessively stepped on the accelerator pedal or brake pedal when the center of gravity of the driver moves forward due to the law of inertia. , The burden on the arm holding the handle is reduced, and the driver can drive in a more stable and flexible posture. Furthermore, the position of the heel support point is the front facing position of the brake pedal, that is, since the heel support point and the brake pedal are arranged on the extension line of the right foot, the toes naturally move forward even in an emergency,
That is, it moves toward the brake pedal.

Further, according to the pedal arrangement of claim 2, the stepping operation from the accelerator pedal to the brake pedal becomes smoother and quicker. Also, since the pedal operation can be delicate and sensitive with a small motion with the heel as the fulcrum, the brake stroke should be a relatively short stroke that allows the brake to be operated with the heel resting on the heel support point. Therefore, it is possible to freely brake with more delicate operation.

Furthermore, according to the structure of the brake pedal of claim 3,
The operation foot does not collide with the lateral surface of the brake pedal at the time of stepping on the accelerator pedal, and an operation error does not occur, and the foot surface of the brake pedal is smoothly guided by the guide plate portion.

Further, the stop plate portion of claim 4 prevents the operating foot from being disengaged to the left of the pedal at the time of changing or stepping on the pedal, and also prevents the left foot from accidentally pressing the brake. At the beginning, such as when changing trains, the left foot unconsciously makes a so-called empty foot depression that operates the clutch vehicle operation, but it prevents the left foot brake pedal depression due to such left foot movement.

According to the heel support point in claim 5, the heel is supported by putting the heel in the recess, and the pedal is operated while rotating the heel in the recess. According to the heel support point of claim 6, the heel is supported by locking the heel on the protrusion, and the pedal is operated with the heel as the support point. By mounting these recesses or protrusions via bearings, the shape can be fitted to the heel, and the heel can be rotated more smoothly.

Further, if the heel support point is provided with a magnet or a magnetic body and the heel portion of footwear to be worn on the operating foot is provided with a magnetic body or a magnet that is attracted to the heel portion, the operating foot heel is used as the heel. The support points make it easier to lock securely.

(Examples) Hereinafter, examples of the present invention will be further described with reference to the accompanying drawings.

FIG. 1 shows a floor structure (pedal arrangement) of a driver's seat in a vehicle driving operation system of the present invention. A brake pedal 10 and an accelerator pedal on the right side thereof are provided on a floor 1 in front of the driver's seat.

The tread surface of the brake pedal 10 should be installed at approximately the same height as the tread surface of the accelerator pedal 11 or at a lower position (when not in use), and the brake stroke should be sufficient with the heel resting on the heel support point 13. The length. Further, as shown in FIG. 2, the brake pedal 10 has a guide plate portion 10a whose end edge on the accelerator pedal side extends downwardly.
And the stop plate 10b extending upward on the opposite side edge are formed so that the operating foot does not hit the lateral surface of the brake pedal when the accelerator pedal 11 is changed to the brake pedal 10. In addition, the brake pedal is operated smoothly, accurately and quickly without slipping off to the left of the pedal.

As shown in FIG. 3, the heel support point 13 is a floor surface (floor plate 1
And the mat 1a) is formed with a hemispherical recess 13a so that the heel of the operating foot is rotatably locked. The heel support point 13 may be any one as long as the heel of the operating foot can rotate freely as a fulcrum for pedal operation and is suitable for supporting weight, and as shown in FIG. By using the protrusion 13b provided with the heel mounting portion 132, the shape can be smoothly rotated and the heel can be easily locked.

Further, by providing the recess 13a or the protrusion 13b with a magnetic material or a magnet, and wearing footwear with a magnet or a magnetic material attached to the heel of the operating foot (not shown), the heel support point 13
It is possible to secure the locking of the operating foot with the heel.

In order to drive the vehicle with the vehicle operation system configured as described above, the heel F1 of the pedal (brake and accelerator pedal) operating foot F is placed on the heel support point 13 as shown in FIGS. Then, with the heel F1 still mounted, the accelerator pedal 10 and the brake pedal 11 are operated while rotating the heel F1 around the heel support point 13. During pedal operation, the driver's own weight is applied to the heel F1 of the operating foot F, and the pedal is operated in a small motion with the heel support point 13 as a fulcrum.

Therefore, while keeping the posture balance of the driver with both feet,
The driver can drive in a stable posture without straining the arm holding the steering wheel. Even when the weight is accelerated forward due to inertial motion during deceleration or stop, the heel of the operating foot along with the left foot
