Description

Acceleration prevention device for vehicle accelerator pedal device {Prevention device for radical accelerating of automobile}

The present invention relates to a rapid acceleration prevention device of an accelerator pedal device for a vehicle, and more particularly, a vehicle that prevents an accident caused by the acceleration by preventing the acceleration of the vehicle even if a driver who wants a rapid braking accidentally presses the accelerator pedal. It relates to a sudden acceleration prevention device of the accelerator pedal device.

In general, 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 of the driver to the left, and an accelerator pedal and a brake pedal are installed in the case of an automatic transmission vehicle.

That is, when the accelerator pedal is pressed, the throttle valve is opened to accelerate, and when the pedal is released from the accelerator pedal, the accelerator pedal is returned to its original position by the return spring and the acceleration is stopped by closing the throttle valve.

The brake pedal is used to decelerate or temporarily stop a running vehicle. When the brake pedal is pressed, disc cylinders and wheel cylinders installed at the front and rear sides of the vehicle are operated by hydraulic pressure, whereby the brake disc and the brake drum operate the vehicle. Braked.

In addition, the clutch pedal is an operating mechanism that transmits or cuts off the rotational power of the crankshaft, which is the driving shaft of the engine, to the transmission side, and uses the clutch pedal when the transmission is shifted in the manual transmission.

However, the accelerator pedal, brake pedal, and clutch pedal mentioned above are arranged side by side at a constant interval, so even if you are in a hurry to stop the vehicle, even if you are a novice driver, an inexperienced driver, or an experienced driver, In other words, the pedal operation is wrong, that is, the brake pedal must be pressed, but the accelerator pedal is often caused.

That is, in the general vehicle accelerator as shown in FIG. 1, when the driver steps on the accelerator pedal 10, the pedal arm 30 is rotated, and the stroke sensor 40 detects the rotation angle of the pedal arm 30 so that the engine When the engine throttle valve 70 is opened by sending a signal to the ECU 60, the acceleration of the vehicle is performed. On the contrary, when the foot is released from the accelerator pedal 10, the stroke sensor 40 detects this and the engine ECU ( Acceleration is stopped as the throttle valve 70 is closed as a signal to 50).

However, when the driver incorrectly presses the brake pedal because the vehicle needs to be suddenly stopped, the pedal sensor 30 is rotated by the accelerator pedal 10 as the stroke sensor 40 normally presses the accelerator pedal 10 strongly. Since it recognizes only the angle and determines that it wants to accelerate, it sends a signal to the engine ECU 60, so that the throttle valve 70 is opened and rapid acceleration of the vehicle is achieved.

Since the misoperation of the accelerator pedal 10 leads to a large accident such as a vehicle damage or a human accident, special attention is required for this and urgent measures are urgently required.

Therefore, the present invention is to solve such a conventional problem, an object of the present invention is to accelerate the vehicle pedal to prevent accidents caused by accident accidentally stepping on the accelerator pedal as a brake pedal in a sudden situation requiring rapid braking It is to provide a device for preventing rapid acceleration of the device.

In order to achieve the object of the present invention, the present invention is provided with an accelerator pedal at the lower end, the upper end is installed to rotate from the hinge portion of the pedal device, the pedal arm to return to the original position by stepping on the accelerator pedal; A stroke sensor for measuring a value according to an angular range of the pedal arm rotated by stepping on the accelerator pedal, and sending the measured value signal to the engine ECU to control the opening and closing of the engine throttle valve; In the vehicle accelerator pedal device made of,

A sensor pressing part installed on the front of the upper end of the pedal arm to operate in the opposite direction of the accelerator pedal at the lower part of the hinge part; It is installed at a certain interval in front of the sensor presser and detects whether the load value when it is in contact with the sensor presser is more than the set value. If the load value is less than the set value, the engine ECU will follow the measured value of the stroke sensor. Open and close the engine throttle valve, and if the load value is over the set value, the engine ECU sends a signal that invalidates the measured value of the stroke sensor so that the engine speed can be changed to the idle mode or the specific mode is used. It is further characterized in that the rapid acceleration of the vehicle due to the malfunction of the accelerator pedal is prevented.

In the present invention, the engine ECU sends a signal to invalidate the measured value of the stroke sensor when the load value generated when the pedal arm contacts the load cell by pressing the accelerator pedal is equal to or greater than a predetermined set value. By converting to prevent the rapid acceleration of the vehicle there is an effect that can prevent in advance the safety accidents that occur.

The reference figure shows the graph of the illustrated state.

The present invention is provided with an accelerator pedal 100 at the lower end, the upper end is installed to rotate the hinge portion 200 of the pedal device, the pedal arm 300 to return to its original position by stepping on the accelerator pedal 100 )and; A stroke sensor 400 which measures a value according to an angular range of the pedal arm 300 rotated by stepping on the accelerator pedal 100 and sends the measured value signal to the engine ECU to control the opening and closing of the engine throttle valve; An accelerator pedal apparatus for a vehicle, comprising: a sensor pressing unit 320 installed on a front surface of an upper end portion 310 of a pedal arm 300 so as to operate in an opposite direction to an accelerator pedal 100 at a lower portion of a hinge portion 200; It is installed at a certain interval in front of the sensor pressing unit 320, and detects whether the load value when the contact with the sensor pressing unit 320 is more than a predetermined set value, and if the load value is less than the set value, the engine ECU The engine throttle valve is opened and closed according to the measured value of the stroke sensor 400, and when the load value is higher than the set value, the engine ECU sends a signal to invalidate the measured value of the stroke sensor 400 to convert the engine speed to the idle mode. Or a load shell 500 to be converted to a specific mode, thereby preventing rapid acceleration of the vehicle due to malfunction of the accelerator pedal 100.

In the present invention as described above, when the driver presses the accelerator pedal 100 of the accelerator pedal device, the stroke sensor 400 measures a value according to an angle range of the pedal arm 300 rotated, and the measured value is the engine ECU (not shown in the figure). To control the opening and closing of the throttle valve (not shown) as in the prior art.

However, in the present invention, by installing a separate load shell 500 in the accelerator pedal device by measuring the load value generated when the pedal arm 300 in contact with the load shell 500, the engine ECU sends a signal to the throttle valve By opening or closing is to prevent accidents due to malfunction of the accelerator pedal 100 in advance.

The present invention is to install a rod shell 500 that can measure the force or load on the accelerator pedal device so that the pedal arm 300 is rotated to contact the pedal arm 300 is in contact with the rod shell 500. The engine ECU was able to measure the load value at that time.

That is, when 50 kgf is applied to the load shell 500 by applying the reference set value of the load shell 500 set as the load value of the sensor pressing unit 320 to 50 kgf or more, the engine ECU is determined to be inconsistent with the vehicle condition. The engine sends a signal to close the throttle valve so that the vehicle is not accelerated and the engine ECU sends a signal to open the throttle valve when it is loaded under 50kgf and judges that it meets the condition of the vehicle.

Looking at the operation of the present invention configured as described above First, after the engine is started to operate the accelerator pedal for acceleration of the vehicle pedal arm 300 is rotated by the hinge portion 200 is also rotated of the pedal arm 300 When the sensor pressing portion 320 is in contact with the load shell 500 and the load value generated at this time is 50kgf or less, the engine ECU sends a signal to open the throttle valve according to the measured value of the stroke sensor 400 to accelerate the vehicle. .

Unlike this, when the driver suddenly presses the brake due to the sudden stop of the vehicle, when the accelerator pedal 100 is strongly stepped on, the pedal arm 300 rotates at a high speed and thus the sensor pressing portion of the pedal arm 300 ( When the load value generated is greater than 50 kgf, the engine 320 sends a signal indicating that the measured value of the stroke sensor 400 is invalid and closes the throttle valve, thereby making the engine speed idle. To prevent the vehicle from accelerating.

Here, the sensor pressing part 320 of the upper end of the pedal arm 300 is formed as a pressing protrusion provided in a protruding form by a predetermined length from the upper end of the pedal arm 300 so as to further improve contactability.
