Description

[0001] The present invention relates to an acceleration accelerator for automobile,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rapid acceleration prevention device for a vehicle acceleration pedal device, and more particularly, To an apparatus for preventing rapid acceleration of an accelerator pedal apparatus.

Generally, an automobile is provided with an accelerator pedal, a brake pedal and a clutch pedal in the case of a manual transmission vehicle from the right side to the left side of the driver, and an accelerator pedal and a brake pedal in the case of an automatic transmission.

That is, when the accelerator pedal is depressed, the throttle valve is opened to accelerate, and when the foot is released from the accelerator pedal, the accelerator pedal is returned by the return spring, and the throttle valve is closed and the acceleration is stopped.

The brake pedal is used when decelerating or temporarily stopping the vehicle while the vehicle is running. When the brake pedal is depressed, the disk cylinder and the wheel cylinder installed on the front and rear sides of the vehicle are actuated by the hydraulic pressure, whereby the brake disk and the brake drum The vehicle is braked.

Further, the clutch pedal is an operating mechanism for transmitting the rotational power of the crankshaft, which is the drive shaft of the engine, to the transmission shaft or disengaging the power, and the clutch pedal is used in the shift of the transmission in the manual transmission.

However, since the above-mentioned accelerator pedal, brake pedal, clutch pedal, etc. are arranged side by side in a straight line with a constant interval, if the vehicle is to be erected in a hurry, even a novice driver, an inexperienced driver or a skilled driver, It is often the case that the pedal operation is incorrect, that is, the brake pedal must be depressed but the accelerator pedal is depressed.

1, when the driver depresses the accelerator pedal 10, the pedal arm 20 is rotated, and the stroke sensor 30 senses the rotational angle of the pedal arm 20, The stroke sensor 30 senses the accelerator pedal 10 when the pedal 10 is released from the accelerator pedal 10 and the accelerator pedal 10 accelerates the vehicle when the engine throttle valve 50 is opened. The engine throttle valve 50 is closed and the acceleration is stopped.

However, when the driver suddenly depresses the accelerator pedal by mistakenly pressing the brake pedal, the stroke sensor 30 recognizes only the angle at which the pedal arm 20 is rotated by the accelerator pedal 10 as usual And sends a signal to the engine ECU 40. The engine throttle valve 50 is thus opened and the vehicle is rapidly accelerated.

If the driver does not intend to accelerate the vehicle rapidly, it will cause serious accidents such as vehicle damage or human accidents.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a vehicular acceleration pedal capable of preventing a safety accident caused by accidental depression of the accelerator pedal And an apparatus for preventing rapid acceleration of the apparatus.

According to an aspect of the present invention, there is provided an accelerator pedal system comprising: an accelerator pedal arm which is changed in stroke range in which a hinge portion of an upper end rotates in a hinge axis in a housing, A stroke sensor for measuring a range of rotation angles of the accelerator pedal arm and sending the measured value signal to the engine ECU to control the opening and closing amount of the engine throttle valve; A push bar protruding forward from a front surface of a support portion provided on an upper surface of the hinge portion so as to be rotated in a direction opposite to the accelerator pedal arm and having a pressing portion at a tip thereof; If the accelerator pedal arm touched suddenly by an abnormal force is out of the normal stroke range, the pushing portion is contacted to increase the operating load of the accelerator pedal arm, and the stroke sensor that senses this causes a predetermined interval in front of the pushing portion to send an abnormal voltage value signal A load increasing mechanism installed and installed; And an engine ECU configured to invalidate the acceleration force of the engine or to switch the engine speed to the idle mode upon receipt of an abnormally low pressure value signal of the stroke sensor, thereby preventing rapid acceleration of the vehicle during the stroke operation of the abnormal accelerator pedal arm .

When the pushing portion of the push bar provided on the accelerator pedal is depressed by pressing the accelerator pedal and the pushing portion of the push bar is pressed strongly against the load increasing mechanism and the operation load of the accelerator pedal arm is increased, the stroke sensor transmits an abnormal voltage value signal to the engine ECU There is an effect that a safety accident caused by rapid acceleration can be prevented in advance by invalidating the acceleration force of the sending engine or converting the engine speed to the idle mode.

According to the present invention, the stroke range in which the upper hinge portion 110 is rotated by the hinge shaft 121 in the housing 120 is changed according to the degree of depression, and the accelerator pedal arm (100); And a stroke sensor (200) for measuring a rotation angle range of the accelerator pedal arm (100) and sending the measured value signal to an engine ECU to control the amount of opening and closing of the engine throttle valve, wherein the accelerator pedal A push bar 140 protruding forward from the front of the support 130 provided on the upper surface of the hinge 110 so as to rotate in a direction opposite to the arm 100 and having a pushing part 141 at the tip, ; When the accelerator pedal arm 100, which is urgently depressed by an abnormal force, is out of the normal stroke range, the pushing portion 141 is contacted to increase the operation load of the accelerator pedal arm 100, and the stroke sensor 200, A load increasing mechanism 300 installed at a predetermined distance in front of the pushing portion 141 to send a voltage value signal; And an engine ECU configured to invalidate the acceleration force of the engine or to switch the engine speed to the idle mode upon receipt of an abnormal voltage value signal of the stroke sensor (200).

In the present invention as described above, the stroke sensor 200 measures the rotation value in accordance with the rotation angle range of the accelerator pedal arm 100 rotated when the driver depresses the accelerator pedal (not shown in the figure) (Not shown in the drawings) to control the opening and closing of the engine throttle valve (not shown in the figure) is the same as in the prior art.

However, the feature of the present invention is that when the accelerator pedal is depressed with an abnormal force, the accelerator pedal overcomes the load increasing mechanism, and the stroke sensor 200 sends an abnormal voltage value generated at this time to the engine ECU to invalidate the acceleration force of the engine, To the idle mode so that the safety accident caused by the rapid acceleration can be prevented in advance.

That is, according to the present invention, when the accelerator pedal is depressed, a push bar 140 protruding forward by a predetermined length is provided on the front surface of the supporter 130, which is rotated in the opposite direction to the accelerator pedal arm 100, And a pressing portion 141 is formed at the tip of the pressing portion 141. [

The push bars 140 may be integrally formed on the support 130 or separately formed.

A load increasing mechanism 300 is provided in front of the pressing portion 141 at a predetermined distance from the pressing portion 141.

In the present invention, the stroke sensor 200 outputs a signal to the engine ECU when the voltage value generated when the pressing portion 141 of the pressing bar 140 contacts the load increasing mechanism 300 by pressing the accelerator pedal is not more than a predetermined set value When the pushing portion 141 of the push bar 140 is moved beyond the load increasing mechanism 300, the stroke sensor 200 sends an abnormal voltage value to the engine ECU (not shown) To close the engine throttle valve to invalidate the acceleration force of the engine or to switch the engine speed to the idle mode.

That is, when the accelerator pedal is smoothly depressed to normally travel the vehicle, since the pushing portion 131 does not exceed the load increasing mechanism 300, the operation load of the accelerator pedal arm 100 is less than the set value, The control unit 200 sends a signal to the engine ECU to open and close the engine throttle valve so that the vehicle can travel at a normal speed.

However, when the driver erroneously depresses the brake pedal to cope with an unexpected situation and the accelerator pedal is strongly depressed by an abnormal force, the accelerator pedal arm 100 is rotated at a high speed, and the support portion 130 of the accelerator pedal arm 100, The operation load of the accelerator pedal arm 100 is increased and the voltage value generated at this time is input to the stroke sensor 200. [ The stroke sensor 200 sends an abnormal voltage value signal to the engine ECU because it is abnormal than the set value.

When the engine ECU receives an abnormal voltage value signal from the stroke sensor 200, the engine ECU closes the engine throttle valve to invalidate the acceleration force of the engine, or converts the revolution speed of the engine into the idle mode, It is prevented in advance.

In the present invention, the pushing portion 141 at the tip of the push bar 140 is formed in a ball shape, and the pushing-up increasing mechanism 300 in which the pushing portion 141 is contacted includes a circular ring- A plurality of mechanical balls 330 are radially provided on the inner circumferential surface of the mechanical guide 310 so as to gather the elastic force toward the center of the mechanical guide 310.

That is, in the present invention, when the accelerator pedal is smoothly pressed in the normal state, the ball-shaped pressing part 131 lightly contacts the mechanical ball 330 of the load increasing mechanism 300, The pressing portion 141 strongly pushes the mechanical ball 330 installed in the mechanical guide 310 of the load increasing mechanism 300. As a result,

When the mechanical ball 330 is mounted on the spring 320 fixed to the tool guide 310 at the rear end and the spring 320 is contracted when a strong force is applied to the mechanical ball 330, The pushing portion 141 is inserted.

As described above, when the pressing portion 141 pushes the mechanical ball 330 and the operating load of the accelerator pedal arm 100 increases during the operation of the abnormal accelerator pedal, the acceleration force of the engine becomes invalid or the engine speed In addition to preventing the vehicle from being rapidly accelerated by switching to the idle mode, the driver can immediately recognize that an abnormal force is applied to the accelerator pedal, thereby releasing the foot from the accelerator pedal to prevent rapid acceleration.

The push bar 140 has a cross sectional area located at the support part 130 and a cross sectional area located at the push part 141 different from each other. This is because the rigidity reinforcement of the support part 130 and the push bar 140 are loaded Increase the length of the device (300) so that it can no longer enter.
