The present invention relates to a rapid acceleration prevention device of an accelerator pedal device for a vehicle. In the related art, when a brake pedal is to be stepped on because of a sudden stop of the vehicle, the vehicle is suddenly accelerated as a result of accidental stepping on the accelerator pedal. There was a problem that led to a major accident.
Therefore, the present invention is provided with an accelerator pedal 100 at the lower end, the upper end is installed to rotate from 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 measuring a value according to an angular range of the pedal arm 300 rotated by stepping on the accelerator pedal 100, and sending the measured value signal to the engine ECU to control the opening and closing of the engine throttle valve; An acceleration pedal device for a vehicle, comprising: a sensor pressing part (320) installed in front of an upper portion (310) of a pedal arm (300) so as to operate opposite to an accelerator pedal (100) around 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 if the load value is higher than the set value, a signal to invalidate the measured value of the stroke sensor 400 is sent to the engine ECU to convert the engine speed to the idle mode. Or a road shell 500 configured to be converted to a specific mode to prevent rapid acceleration of the vehicle due to a malfunction of the accelerator pedal 100. The present invention provides a pedal arm that is rotated by the accelerator pedal 100. When the load value when 300 is in contact with the load shell 500 is equal to or greater than the set value input to the load shell 500, a signal for invalidating the measured value of the stroke sensor 400 is sent to the engine ECU to determine the engine speed. Children Or converted into a useful invention in the damage and personal injury to be converted to a particular mode resulting hameuroseo avoid sudden acceleration of the vehicle the vehicle can be prevented.
Description
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
However, when the driver incorrectly presses the brake pedal because the vehicle needs to be suddenly stopped, the
Since the misoperation of the
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.
