Description

Mechanical fuel control system for responding to sudden vehicle acceleration

[0001] The present invention relates to a mechanical fuel control system for responding to sudden acceleration of a vehicle, and more particularly, to a mechanical fuel control system for responding to sudden acceleration of a vehicle, which induces an easy and quick physical operation from a driver when the vehicle suddenly accelerates, and blocks fuel supplied to the engine of the vehicle due to the physical operation by the driver, thereby controlling the power of the vehicle due to the fuel cut, thereby preventing in advance a major traffic accident caused by sudden acceleration of the vehicle, such as an accident involving people and property damage, including the driver and passengers, in the vicinity.

[0002] Sudden acceleration of the vehicle,

[0003] A phenomenon in which a vehicle accelerates without the driver's control or will.

[0004] It can occur when the vehicle is stationary, at low speeds, or while driving at a constant speed, and is usually accompanied by a failure of the brakes.

[0005] There is debate as to whether the cause of this sudden acceleration phenomenon is the driver's inexperience or a mechanical or electrical defect in the vehicle.

[0006] One of the causes of sudden acceleration is a mechanical or electrical defect in the vehicle.

[0007] While the vehicle is in operation, the ECU (Electronic Control Unit) temporarily stops for some reason, and the throttle valve that controls the ECU (Electronic Control Unit) is not controlled, so the entire valve opens and a force greater than the force with which the driver pressed the accelerator pedal is input, causing the speed to suddenly accelerate. Even if the driver presses the brake pedal, control is impossible because the throttle valve is already open too much.

[0008] However, current countermeasures for sudden acceleration, such as pressing the brake hard at once, shifting to neutral, applying the side brake, and turning off the engine, are difficult to control in an emergency situation when the driver tries to control the vehicle that has already suddenly accelerated.

[0009] That is, the sudden acceleration of the vehicle,

[0010] This is a very dangerous accident that can lead to a major accident because it occurs suddenly without warning symptoms, regardless of the driver's intention, including internal combustion engine and electric vehicles. However, it is very difficult to clearly identify the exact cause, and the countermeasures are also not very effective.

[0011] Therefore, the present invention,

[0012] In response to the need for an effective method for preventing sudden acceleration of a vehicle that is not intended by the driver, a mechanical fuel control system for responding to sudden acceleration of a vehicle is provided, which is formed and operated by a mechanical structure that is independent of the electric or electronic system of the vehicle and that allows the driver to respond quickly and easily, thereby enabling the vehicle to be controlled in the event of sudden acceleration, thereby preventing the occurrence of major traffic accidents in advance.

[0013] Accordingly, as a prior art regarding a mechanical fuel control system for responding to sudden acceleration of a vehicle,

[0014] As shown in (a) of Fig. 5,

[0015] Korean Patent Publication No. 10-1407998, “A device for preventing sudden acceleration of a vehicle and a method for controlling the same” (hereinafter referred to as “prior art 1”),

[0016] The present invention relates to a sudden acceleration prevention device for a vehicle and a control method thereof, which comprises an electronically controlled throttle module for opening and closing a throttle, a pedal position detection unit for detecting the position of an accelerator pedal, a sudden acceleration control unit for receiving driving status information of a vehicle by being connected to a terminal of a self-diagnosis device of a vehicle to determine whether sudden acceleration has occurred and generating a motor drive control signal to adjust the amount of intake air supplied to an engine when sudden acceleration has occurred, and a signal selection unit for selectively transmitting a control signal of a vehicle control unit provided in a vehicle and the motor drive control signal to the electronically controlled throttle module, wherein the sudden acceleration control unit generates the motor drive control signal when sudden acceleration is determined to have occurred and controls the electronically controlled throttle module to open a throttle opening amount corresponding to an idle state, and determines whether a malfunction of the vehicle control unit and sudden acceleration has occurred using driving status information of the vehicle transmitted through an OBD terminal, and prevents an accident caused by sudden acceleration by adjusting the amount of intake air supplied to the engine to an idle state when sudden acceleration has occurred.

[0017] Another prior art is,

[0018] As shown in (b) of Fig. 5,

[0019] As for the “brake system for forcibly stopping a vehicle when it suddenly accelerates” of the Korean Patent Publication No. 10-1543559 (hereinafter referred to as “prior art 2”),

[0020] A blocking cylinder with a blocking rod mounted inside and mounted inside the blocking cylinder, which is protruded when hydraulic pressure is generated and inserted directly into the empty space between the spokes of the disc wheel, or

[0021] The present invention relates to a brake system for forcibly stopping a vehicle in the event of sudden acceleration, which includes a blocking bar that forcibly blocks the rotation of a disc wheel by being further protruded and inserted into an empty space by hydraulic pressure applied when the spoke is further rotated while first being in contact with the spoke, thereby completely blocking the rotation of the wheel by a method of catching rather than a method of friction when an engine abnormality is detected, thereby preventing a major accident in advance.

[0022] As examined, the above prior art 1 and prior art 2 are related to a device and system for preventing sudden acceleration of a vehicle similar to and identical to the present invention, and although there are similar and identical technical concepts in the basic components of the invention, there are differences in specific solutions for solving them, problems to be solved, and the effects of the invention through them.

[0023] That is, prior art 1 is,

[0024] The purpose is to provide a vehicle sudden acceleration prevention device and its control method that prevents sudden acceleration by controlling the amount of intake air supplied to the engine when the vehicle suddenly accelerates.

[0025] Prior art 2 is,

[0026] This is a technology that aims to prevent major accidents in advance by completely blocking the rotation of the wheels through a catch method rather than a friction method when an engine abnormality is detected.

[0027] In contrast to the present invention,

[0028] There are differences in the technical characteristics of the specific means (components) of the invention to solve the problem that the invention seeks to solve and to exert its effect.

[0029] Therefore, the present invention seeks to achieve its technical features based on the problem to be solved (purpose of the invention), the means for solving the problem (component) and the effect exhibited by solving the problem, which are different from the conventional technology for preventing sudden acceleration of a vehicle, including the above-mentioned prior art 1 and prior art 2.

[0137] In more detail,

[0138] The fuel storage tank section (100) is

[0139] A component that stores fuel supplied to the vehicle from outside.

[0140] Fuel tank module (110) where fuel is stored;

[0141] A fuel pump module (120) positioned and formed inside or near the fuel tank module (110) to transfer fuel stored in the fuel tank module (110) to the fuel injector module (140);

[0142] A fuel filter module (130) that filters out foreign substances and moisture in the fuel transferred to the fuel injector module (140) by the fuel pump module (120) to protect the engine unit (200) and ensure that high-quality fuel is supplied to the engine unit (200);

[0143] It is composed of a fuel injector module (140) that supplies and sprays fuel that is pressurized by the fuel pump module (120) and passes through the fuel filter module (130) to the engine unit (200).

[0144] Ensures that the fuel needed to generate power for the vehicle is safely stored.

[0145] The engine section (200) is

[0146] A component that mixes and combusts fuel supplied from the fuel storage tank (100) and air sucked in from the outside to generate power necessary for driving the vehicle.

[0147] In short, in the case of an internal combustion engine,

[0148] A cylinder head module (210) attached to a cylinder block module (220) to allow a mixture of fuel and air to flow into the cylinder;

[0149] The cylinder block module (220), which is the part to which the above cylinder head module (210) is attached, is a space where various parts for generating power for the vehicle, such as cylinders, pistons, crank shafts, and cam shafts, operate;

[0150] It is formed and positioned between the cylinder head module (210) and the cylinder block module (220), and is composed of a valve opening device module (230) that controls the opening and closing of the valve.

[0151] It generates the power required to drive the vehicle.

[0152] The fuel supply line section (300) is

[0153] A component composed of a pipe that forms a path for fuel to move from the fuel storage tank (100) to the engine section (200).

[0154] Some components of the above mechanical acceleration control unit (400) are positioned and formed within the fuel supply line unit (300),

[0155] By organically combining the fuel supply line section (300) and the mechanical acceleration control section (400), the path of fuel supplied from the fuel storage tank section (100) to the engine section (200) is blocked or opened depending on the situation.

[0156] The mechanical acceleration control unit (400) is

[0157] When the vehicle accelerates suddenly, the mechanical acceleration control unit (400) controls the fuel supplied to the engine unit (200) by blocking the fuel supply line unit (300) through physical manipulation by the driver.

[0158] It is formed with a one-touch structure so that the driver can operate it quickly and easily.

[0159] By minimizing the connection points with the fuel supply line section (300) that forms the fuel movement path so that the fuel stored in the fuel storage tank section (100) is supplied to the engine section (200),

[0160] It is characterized by maximizing the blocking responsiveness of the fuel supply line section (300) due to the activation of the mechanical acceleration control section (400).

[0161] A fuel supply control valve module (410) located and formed in a section of the fuel supply line section (300) to open or block the supply of fuel from the fuel storage tank section (100) to the engine section (200) depending on the situation;

[0162] A physical acceleration control operation module (420) formed in a one-touch structure that is positioned and formed on one side of the vehicle's interior center fascia, close to the driver, and allows the driver to physically operate it quickly and easily depending on the situation;

[0163] It is composed of a mechanical sudden acceleration control pivot connection module (430) that connects the fuel supply control valve module (410) and the physical sudden acceleration control operation module (420), and blocks and opens the fuel supply control valve module (410) by the driver's operation of the physical sudden acceleration control operation module (420).

[0164] It is characterized by being able to respond quickly and easily in the event of a sudden acceleration of the vehicle that the driver does not intend, thereby enabling the driver to control the driving of the vehicle.

[0165]

[0166] *At this time, the physical acceleration control operation module (420)

[0167] It is positioned within easy reach of the driver's hand so that the driver can quickly and easily activate it when the vehicle accelerates suddenly.

[0168] It is formed with an intuitive mechanical structure so that the driver can immediately recognize the physical acceleration control operation module (420) in any situation, including normal times and urgent situations.

[0169] By forming a one-touch structure for easy operation,

[0170] Maximizes driver awareness and operability.

[0171] That is, for example,

[0172] It can be formed into a mechanical structure that is easy for the driver to access and operate, such as a lever structure or button structure,

[0173] To prevent accidental use, clearly indicate its function and role.

[0174]

[0175] *It is desirable to configure it so that it is easy to use and can be quickly activated by the driver.

[0176] In addition, the mechanical acceleration control pivot connection module (430)

[0177] It is formed so that the mechanical external force loss caused by physical operation by the driver is minimized through the physical acceleration control operation module (420) and efficiently transmitted to the fuel supply control valve module (410).

[0178] Maximizes responsiveness to vehicle control.

[0179] That is, for example, by using a cable structure and link structure formed of a flexible material, it is possible to flexibly pass through other components located inside the vehicle without interfering with them, and the number of connection points required for connection between the physical acceleration control operation module (420) and the fuel supply control valve module (410) is minimized.

[0180] By directly transmitting the mechanical external force generated by the physical operation by the driver as a force to block the fuel supply control valve module (410),

[0181] Maximizes reliability and responsiveness.

[0182] Meanwhile, the inventor of the present invention, a mechanical fuel control system (1) for responding to sudden acceleration of a vehicle,

[0183] The total length of the fuel supply line section (300), i.e., the total length of the path of movement of fuel supplied from the fuel storage tank section (100) to the engine section (200) through the fuel supply line section (300), is denoted by 'L'.

[0184] The distance between the fuel storage tank section (100) and the fuel supply control valve module (410) formed in a section of the fuel supply line section (300) is 'Lt'.

[0185] When the distance between the engine section (200) and the fuel supply control valve module (410) located and formed in a part of the fuel supply line section (300) is 'Le',

[0186] In order to quickly control the power generated from the engine section (200),

[0187] Inequality

[0188] Lt ≥ Le

[0189] The fuel supply control valve module (410) is formed at the position where the valve is established.

[0190] That is, as the fuel supply control valve module (410) gets closer to the engine section (200), it blocks the fuel supplied to the engine section (200), quickly exhausts the fuel supplied to the engine section (200), and thus enables the power generated from the engine section (200) by the supply of fuel to be quickly controlled.

[0191] In addition, on the other hand, the mechanical fuel control system (1) for responding to sudden acceleration of a vehicle according to the present invention,

[0192] A physical operation sudden activation prevention unit (500) is further included and configured to prevent the activation of the mechanical sudden acceleration control unit (400) that may be accidentally caused by the driver or by external force.

[0193] In addition to the artificial external force generated by the physical operation of the driver when the vehicle suddenly accelerates, the accidental activation of the mechanical sudden acceleration control unit (400) due to the driver's light touch or other various factors is prevented, so that the safe driving of the vehicle can be aimed at as a top priority.

[0194] That is, for example,

[0195] Only when the driver applies the same external force for a certain period of time or operates the physical acceleration control operation module (420) with increasingly stronger external force,

[0196] By ensuring that the fuel supply control valve module (410) is continuously shut off,

[0197] Blocks the path of fuel supplied to the engine section (200), allowing the driver to control the vehicle.

[0198] On the contrary,

[0199] When a light touch, momentary external force, i.e., a momentary, single-shot external force is applied to the physical acceleration control operation module (420),

[0200] By ensuring that the fuel supply control valve module (410) is continuously opened,

[0201] The route of movement of fuel supplied to the engine section (200) is secured safely to ensure safe driving of the vehicle.

[0202] As described above, the present invention,

[0203] When the driver suddenly accelerates the vehicle, he / she can quickly and easily control the vehicle by manually operating it.

[0204] The present invention relates to a mechanical fuel control system (1) for responding to sudden acceleration of a vehicle with maximum reliability, responsiveness, and durability by minimizing manual operation by a driver and the intermediate process of controlling the vehicle thereby.

[0205] That is, the present invention,

[0206] By seeking an organic coupling relationship that completes the minimum and optimized mechanism between the mechanical acceleration control unit (400) and the fuel supply line unit (300),

[0207] The purpose is to quickly block the path of fuel supplied to the engine section (200) and prevent major traffic accidents caused by sudden acceleration of the vehicle.

[0208] Meanwhile, the inventor of the present invention, a mechanical fuel control system (1) for responding to sudden acceleration of a vehicle,

[0210] It can quickly and effectively notify the public of an emergency situation involving a vehicle, and minimize damage to people and property caused by sudden acceleration of the vehicle.

[0211] That is, when the vehicle sudden acceleration control function is activated, power is supplied so that the vehicle's emergency lights flash,

[0212] This allows other vehicles or pedestrians outside to quickly identify and recognize the vehicle's emergency situation and avoid vehicles with flashing emergency lights.

[0213] We strive to prevent further major traffic accidents in advance.

[0214] For reference, the present invention,

[0215] If the vehicle accelerates suddenly without the driver's intention,

[0216] By the driver closing a section of the fuel supply line (300) through the mechanical acceleration control unit (400), the fuel supply to the engine unit (200) is blocked, and the power generated from the engine unit (200) required for vehicle operation is controlled.

[0218] for example,

[0219] The time when the vehicle accelerates suddenly and the vehicle accelerates until the vehicle accelerates and the vehicle accelerates until the vehicle exhausts fuel.

[0220] That is, when the shortest duration of a vehicle's sudden acceleration, from the time when the vehicle's sudden acceleration begins until the sudden acceleration ends due to fuel exhaustion, is called 'SUA(t)',

[0221] The shortest duration of sudden acceleration of a vehicle, 'SUA(t),' is

[0222] SUA(t) = λ / K,

[0223] K = Q * 1 / V,

[0224] V = Pcs * Le,

[0225] Pcs = (πD 2 ) / 4,

[0226] That is, SUA(t) = (λ * Pcs * Le) / Q

[0227] is derived as,

[0228] Depending on the situation, the shortest acceleration duration information of the vehicle derived from the above formula can be visually provided to the driver, allowing the driver to control the vehicle more safely for the remaining time.

[0229] 'λ' is the friction loss coefficient inside the fuel supply line (300),

[0230] (Assuming the fuel flow is laminar, where λ = 64 / Re, where Re is the Reynolds number)

[0231] 'K' is the amount of fuel per hour that generates the power required to drive the vehicle divided by the volume of the fuel supply line (300).

[0232] 'Q' is the amount of fuel per hour that generates the power required to drive the vehicle from the engine unit (200).

[0233] 'V' is the volume of the fuel supply line section (300) from the engine section (200) to the location where the fuel supply control valve module (410) is installed.

[0234] 'Pcs' is the cross-sectional area of ​​the fuel supply line (300),

[0235] (In case of circular shape, 'D' is the diameter of the fuel supply line section (300)),

[0236] 'Le' is the distance from the engine section (200) to the location where the fuel supply control valve module (410) is installed.

[0237] is defined as

[0238] That is, when a sudden acceleration of the vehicle is detected, the sudden acceleration continues only for 'SUA(t)', and thereafter, the power of the engine unit (200) is lost, the vehicle stops, and the driver can safely control the vehicle.

[0239] As described above, it is obvious to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and variations can be made without departing from the spirit and scope of the present invention.

[0240] Accordingly, the embodiments of the present invention are merely illustrative in all respects and should not be construed as limiting, as they can be implemented in various other forms without departing from the technical idea or main characteristics, and can be implemented in various modified forms.

[0241] The present invention relates to a mechanical fuel control system for responding to sudden acceleration of a vehicle.
