Description
BACKGROUND OF THE
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
However, when the driver suddenly depresses the accelerator pedal by mistakenly pressing the brake pedal, the
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.
