Description

Technology Field

[0001] The present invention relates to a device for preventing sudden acceleration of a vehicle caused by human error, and more specifically, to a device that sends an alarm (warning light and warning sound) to the driver when the vehicle accelerates rapidly because the driver mistakes the accelerator pedal for the brake pedal and presses the accelerator pedal all the way down. In particular, the present invention is designed to provide a vehicle sudden acceleration warning device configured to allow anyone to easily install it by eliminating the need for installation work by a professional, by having a structure in which a sensor is attached to the side of the accelerator pedal component and a corresponding position. Background Technology

[0002] As is well known, sudden acceleration is a phenomenon that frequently occurs in vehicles equipped with an electronic control system (ECU). It refers to a situation where, upon starting a vehicle from a standstill, the engine's rotational speed (RPM) rises rapidly, causing the vehicle to move forward or backward at high speed or repeatedly move back and forth, resulting in material and human damage to the surroundings.

[0003] Therefore, numerous technologies have been proposed in the past to prevent sudden acceleration accidents in such vehicles.

[0004] Upon examining these technologies, a technique has been proposed to prevent sudden acceleration by cutting off the fuel supply to the engine to prevent it from starting when the clutch fails to operate due to a malfunction in the clutch hydraulic circuit or similar factors when the clutch pedal is pressed; however, this requires a separate mechanical configuration, which leads to increased manufacturing costs and the problem of being unable to identify the cause of the sudden acceleration.

[0005] Existing methods to prevent sudden acceleration are relatively expensive because they control the vehicle by installing separate, complex systems. Furthermore, additional installation costs are incurred as expert installation is required to connect the prevention system to the vehicle's control system.

[0006] In addition, in some cases, it presents the problem that it is difficult to install on existing vehicles and can only be applied during the new car manufacturing process.

[0007] Due to the rapid aging of the population, the number of elderly drivers is increasing rapidly, leading to a rise in accidents caused by confusing the brake and accelerator pedals. Consequently, there is a need for the rapid dissemination of devices to prevent sudden acceleration caused by human error; however, the high price and installation costs of existing products place a burden on users, making the rapid adoption of such devices difficult.

Specific details for implementing the invention

[0024] The present invention will be described below with reference to the attached drawings. However, the present invention may be implemented in various different forms and is therefore not limited to the embodiments described herein. Furthermore, in order to clearly explain the present invention in the drawings, parts unrelated to the explanation have been omitted, and similar parts throughout the specification have been given similar reference numerals.

[0025] Throughout the specification, when it is stated that a part is "connected" to another part, this includes not only cases where they are "directly connected," but also cases where they are "indirectly connected" with other members interposed between them. Furthermore, when it is stated that a part "includes" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but rather allows for the inclusion of additional components.

[0026] Embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0027] FIGS. 1 and FIGS. 2 are side views illustrating a situation in which a vehicle rapid acceleration warning device due to human error is installed and operated on an upper fixed or lower fixed accelerator pedal according to a preferred embodiment of the present invention.

[0028] Referring to FIGS. 1 and 2, a vehicle rapid acceleration warning device due to human error according to a preferred embodiment of the present invention is characterized by comprising: an attachment part (50) installed to have a certain area at or near the end opposite the rotation axis of an accelerator pedal (10); a sensor (20) attached to the attachment part (50) and formed to have a certain volume and move together with the accelerator pedal (10); a detection part (30) installed to face the end opposite the rotation axis when the accelerator pedal (10) is pressed to rotate to the maximum extent; and an alarm part (50) that receives a proximity detection signal output from the detection part (30) when the sensor (20) approaches the detection part (30) within a preset distance and generates an alarm that can be recognized by the surroundings.

[0029] Here, the warning generated by the warning unit (50) may use either a warning sound or a warning light that can be recognized by people in the vehicle, or both. In the case of a warning light, it is thought that a method in which the light flashes at regular intervals is more advantageous for recognizing a dangerous situation.

[0030] In addition, in addition to warnings using sound or light, methods such as displaying warning messages on the vehicle's interior display screen or using tactile methods where specific points on the seat protrude to alert the occupant to dangerous situations may also be utilized.

[0031] When an alarm is triggered using sound or lights, it is easy for all occupants in the vehicle to simultaneously recognize the dangerous situation. In contrast, methods that display warning messages on a screen or utilize tactile feedback increase implementation costs or are likely to result in delayed occupant recognition after the alarm is triggered. Therefore, it is recommended to use a warning sound or a repeated ON / OFF method for warning lights, or to use both methods together, as the basic means of triggering an alarm.

[0032] Additionally, the attachment part (50) can be implemented using Velcro, which is also commonly referred to as a "hook and loop fastener," and may be fixed to one side of the accelerator pedal (10) with a certain area at the opposite end of the hinge fixing part of one end of the vehicle's accelerator pedal (10) or near thereto, or fixed in a form that wraps around the other end of the accelerator pedal (10) and near thereto.

[0033] In addition, the entire surface or at least one side of the sensor (20) is implemented with Velcro so that the sensor (20) can be maintained attached to one side of the accelerator pedal (10).

[0034] As described above, by using a method of attaching the sensor (20) using Velcro, the vehicle rapid acceleration warning device due to human error according to a preferred embodiment of the present invention can be installed more easily.

[0035] FIG. 3 is a block diagram illustrating the operation sequence of a vehicle rapid acceleration warning device due to human error according to a preferred embodiment of the present invention.

[0036] Referring to FIG. 3, a vehicle rapid acceleration warning device due to human error according to a preferred embodiment of the present invention outputs a proximity detection signal from the detection unit (30) through the interaction between the sensor (20) and the detection unit (30) when the accelerator pedal (10) is pressed and the other end of the accelerator pedal (10), on which the attachment unit (50) and the sensor (20) are installed, reaches the end of the movement range or the vicinity thereof, and this output signal is transmitted to the warning unit (40) to generate an alarm.

[0037] At this time, the warning that informs the occupant of a dangerous situation basically uses the generation of an alarm sound or the repeated illumination of a warning light, as described with reference to FIGS. 1 and 2, and can be implemented by using both together.

[0038] In addition, as described above, a method of displaying a warning message on an in-vehicle display screen, a tactile delivery method utilizing a certain part of the seat, etc., can be selected and used in combination with a warning delivery method using an alarm sound or a warning light.

[0039] Additionally, with reference to each drawing from FIGS. 1 to 3, as a method for proximity recognition used in the sensor (20) and detection unit (30) included in the vehicle rapid acceleration warning device due to human error according to a preferred embodiment of the present invention, any one of the high-frequency oscillation type (induction type), capacitive type, infrared type, ultrasonic type, and magnetic type may be selectively used.

[0040] Operation using each method listed as selectable and implementable can be briefly explained as follows.

[0041] In addition, according to a preferred embodiment of the present invention, the sensor (20) of the vehicle's rapid acceleration warning device due to human error is formed of a conductive material, and the detection unit (30) is characterized by oscillating a high frequency during operation and outputting a proximity detection signal when the amplitude of the oscillation generated as the sensor (30) approaches the high frequency magnetic field decreases to a preset value or less.

[0042] In addition, according to a preferred embodiment of the present invention, the detection unit (30) of the vehicle rapid acceleration warning device due to human error detects a change in capacitance between the sensor (20) and the detection unit (30), and outputs a proximity detection signal when the sensor (20) approaches the detection unit (30) and a change in capacitance occurs, and the amount of the change exceeds a preset value.

[0043] In addition, according to a preferred embodiment of the present invention, the detection unit (30) of the vehicle rapid acceleration warning device due to human error emits infrared light and measures the amount of infrared light reflected from the sensor to determine the distance between the sensor (20) and the detection unit (30), and outputs a proximity detection signal when the distance becomes less than or equal to a preset value.

[0044] In addition, according to a preferred embodiment of the present invention, the detection unit (30) of the vehicle rapid acceleration warning device due to human error generates a magnetic field during operation, and the sensor (20) recognizes a change in the magnetic field when it approaches the detection unit (30), and outputs a proximity detection signal when the amount of change in the magnetic field exceeds a set range.

[0045] With reference to the drawings from Fig. 1 to Fig. 3, the installation and operation of a vehicle rapid acceleration warning device due to human error according to a preferred embodiment of the present invention have been described.
