Description

[0001] DESCRIPTION [0002] Accelerating pedal device for vehicle [

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an accelerator pedal apparatus for an automobile, and more particularly to an accelerator pedal apparatus for an automobile which adjusts the degree of opening and closing of a throttle valve while being connected to a throttle valve body of an automobile.

Generally, an accelerator pedal of an automobile regulates an opening amount of a throttle valve of an engine intake port to regulate the amount of air sucked into the engine. The amount of air sucked into the engine determines the amount of fuel injected into the cylinder, which ultimately determines the number of revolutions and fuel consumption of the engine. Most of these throttle valves are either mechanically connected to the accelerator pedal and the wires or are electrically connected using a microcontroller.

In this case, as the number of revolutions of the engine suddenly increases, the injection quantity of the fuel increases. In the past, the acceleration is determined according to the speed at which the driver depresses the accelerator pedal. Thus, Acceleration causes a problem of consuming a larger amount of fuel than when accelerating slowly.

Such a conventional automotive accelerator pedal device is disclosed in Korean Patent Laid-Open No. 10-1998-021875 (Jun. 25, 1998).

It is an object of the present invention to provide an accelerator pedal device for an automobile which enables a driver to selectively perform a pedal operation for rapid acceleration of a car or a pedal operation for saving fuel.

The present invention relates to an accelerator pedal apparatus for an automobile which adjusts the opening and closing of a throttle valve in a state of being connected to a throttle valve body of an automobile. The accelerator pedal apparatus is connected to the throttle valve body by a first cable, A second accelerator pedal which is provided adjacent to the first accelerator pedal, a second accelerator pedal which is connected to the second accelerator pedal and the throttle valve body, And an acceleration regulator for controlling the throttle valve of the automobile to be opened or closed at a constant speed irrespective of the speed at which the driver depresses the second accelerator pedal.

Also, the second accelerator pedal may be electrically connected to the acceleration regulator, and the acceleration regulator may be connected to the throttle valve body by a second cable.

The acceleration regulator may further include a servo motor connected to the throttle valve body and the second cable for generating a driving force to open and close the throttle valve in accordance with a stepping motion of the second accelerator pedal, The second accelerator pedal is electrically connected to the servo motor and the second accelerator pedal while being disposed between the first accelerator pedal and the second accelerator pedal so that the rotational speed of the servomotor is kept constant regardless of the pressing speed of the second accelerator pedal, And a control unit for causing the throttle valve to be opened and closed at a constant speed.

The accelerator pedal apparatus for an automobile according to the present invention is characterized in that when a driver pivots the first accelerator pedal connected to the throttle valve body by the first cable, the throttle valve is opened or closed corresponding to the revolving speed of the first accelerator pedal, When the driver depresses the second accelerator pedal connected to the throttle valve body by the acceleration adjusting unit, the throttle valve is opened at a constant speed regardless of the turning speed of the second accelerator pedal, It is possible to prevent the acceleration, thereby increasing the fuel consumption efficiency.

1 is a schematic block diagram of an automotive accelerator pedal apparatus according to an embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1 is a schematic block diagram of an automotive accelerator pedal apparatus according to an embodiment of the present invention. Referring to FIG. 1, the automotive accelerator pedal apparatus includes a first accelerator pedal 100, a second accelerator pedal 200, and an acceleration control unit 300.

The first accelerator pedal 100 is a pedal for opening / closing the throttle valve by a depressing operation of the driver in a state of being connected to the throttle valve body 10 of the automobile. That is, the first accelerator pedal 100 is mechanically connected to the throttle valve body 10 via the first cable 110 in a state where the first accelerator pedal 100 is pivotally hinged to one side of an automobile. Accordingly, the first accelerator pedal 100 is rotated by the pressing force of the driver to open the throttle valve. Here, the first accelerator pedal 100 determines the throttle opening / closing speed of the automobile in accordance with the depression speed of the driver. When the depression speed of the driver is fast, the throttle valve opening speed is increased, Acceleration can be enabled.

The second accelerator pedal 200 is connected to the acceleration controller 300 to be described later in a state where the second accelerator pedal 200 is installed adjacent to the first accelerator pedal 100 so that the opening and closing operation of the throttle valve by the acceleration controller 300 To be operated. The second accelerator pedal 200 is electrically connected to the acceleration regulator 300 in a state where the second accelerator pedal 200 is rotatably hinged to one side of the automobile in a configuration separate from the first accelerator pedal 100. Accordingly, the second accelerator pedal 200 is provided with a signal generating unit (not shown) for transmitting a signal, which is turned by the second accelerator pedal 200, to the acceleration adjusting unit 300 when the second accelerator pedal 200 is rotated by the pressing force of the driver May be provided. It should be noted that the signal generator may be configured to vary a signal transmitted to the acceleration controller 300 according to an angular range of rotation of the second accelerator pedal 200.

The acceleration regulator 300 receives the rotation signal from the second accelerator pedal 200 and rotates the second accelerator pedal 200 when the second accelerator pedal 200 is pivoted by the driver, The throttle valve is controlled to be opened and closed at a constant speed regardless of the rotation speed of the throttle valve. That is, the acceleration regulating unit 300 can open / close the throttle valve only at a predetermined speed irrespective of the rotational speed of the second accelerator pedal 200 by the driver, So that the fuel consumption efficiency can be increased. The acceleration regulator 300 is disposed between the second accelerator pedal 200 and the throttle valve body 10 to be connected to the second accelerator pedal 200 and the throttle valve body 100. At this time, the acceleration regulator 300 is electrically connected to the second accelerator pedal 200 through the wire 302, and receives the rotation signal of the second accelerator pedal 200. The acceleration regulator 300 is mechanically connected to the throttle valve body 10 through the second cable 301. When the rotation signal of the second accelerator pedal 200 is transmitted, And a driving force is generated so that the throttle valve is opened and closed. Here, the acceleration regulator 300 includes a servo motor 310 and a controller 320.

The servomotor 310 generates a driving force such that the throttle valve is opened and closed when the driver rotates by depressing the second accelerator pedal 200. The servo motor 310 is mechanically connected to the throttle valve body 10 through the second cable 301 while being disposed between the throttle valve body 10 and the control unit 320, And is electrically connected to the second electrode 320 through the electric wire 302. In this way, the servomotor 310 is operated only when the control unit 320 receives the rotation signal corresponding to the depressing operation of the second accelerator pedal 200, thereby opening the throttle valve. At this time, the servomotor 310 maintains the opening / closing speed of the throttle valve constant while keeping the moving speed of the second cable 301 constant while generating a rotational force of a constant speed by the controller 320 .

The control unit 320 receives a rotation signal and generates a driving signal to drive the servo motor 310 when the second pivoting of the second accelerator pedal 200 is performed by the driver. The control unit 320 controls the electric power supplied to the servo motor 310 and the second accelerator pedal 200 from the electric wire 302 to the servo motor 310 and the second accelerator pedal 200, ). In this way, the controller 320 generates the drive control signal so that the servo motor 410 generates the rotational force at a constant speed irrespective of the depression speed of the second accelerator pedal 200 by the driver, So that the opening / closing speed of the throttle valve by the motor 410 is kept constant. When the second acceleration pedal 200 receives a different rotation signal from the signal generating unit of the second accelerator pedal 200 in accordance with the rotation range of the second accelerator pedal 200, The degree of opening of the throttle valve may be controlled to be different according to the range of the angular range of rotation of the pedal 200.

The accelerator operation of the vehicle using the accelerator pedal apparatus according to one embodiment of the present invention will now be described. The driver of the automobile selectively drives the first accelerator pedal 100 or the second accelerator pedal 200 So that the opening and closing of the throttle valve can be controlled. That is, when the degree of opening and closing of the throttle valve is adjusted while varying the degree of depression of the first accelerator pedal 100, the opening and closing speed of the throttle valve is also directly operated corresponding to the depression speed of the first accelerator pedal 100 While allowing the vehicle to accelerate or decelerate immediately. Accordingly, when the speed at which the first accelerator pedal 100 is depressed is fast, the opening and closing speed of the throttle valve is also increased, so that rapid acceleration may occur and fuel waste may occur.

On the other hand, when the second accelerator pedal 200 is pivoted, the signal generated by the pivoting is transmitted to the controller 320 of the acceleration regulator 300. At this time, a signal transmitted from the second accelerator pedal 200 to the controller 320 is transmitted to the servomotor 310, regardless of the rotating speed of the first accelerator pedal 200, The fuel consumption efficiency can be increased while preventing rapid acceleration.

As described above, in the automotive accelerator pedal device of the embodiment, when the driver depresses the first accelerator pedal 100 connected to the throttle valve body 10 by the first cable 110, 1, the throttle valve is opened and closed corresponding to the rotation speed of the accelerator pedal 100 so that the accelerator pedal 100 can be rapidly accelerated while the accelerator pedal 100 is operated. The acceleration regulator 300 can open the throttle valve at a constant speed to prevent rapid acceleration regardless of the rotation speed of the second accelerator pedal 200 when the driver steps on the accelerator pedal 200 Thereby increasing the fuel consumption efficiency.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
