Accident prevention device and method through output control according to vehicle location}

The present invention relates to an accident prevention device and accident prevention method through output control according to the vehicle location. More specifically, the present invention relates to an accident prevention device and an accident prevention method through output control according to the vehicle location. More specifically, the electric signal according to the amount of stepping on the operation module sensed in real time from the sensing module according to the driver's operation is expressed as a percentage. Depending on whether the current position detected by the converted percentage and the position detection module corresponds to the determined position and the operation time of the operation module, the output of the throttle valve motor part is limited or the current applied to the drive motor is blocked to control the vehicle. Accidents through output control according to vehicle location, which protects drivers and passengers by preventing sudden acceleration, protects lives by preventing secondary sudden acceleration accidents, and improves the reliability and stability of internal combustion engine vehicles, electric vehicles, or autonomous vehicles. It is about preventive devices and accident prevention methods.

Generally, the driver of a vehicle operates the vehicle by selectively manipulating the accelerator pedal and brake pedal depending on the situation to accelerate or brake the vehicle.

Drivers generally control the degree of acceleration and braking by adjusting the degree to which they press the accelerator and brake pedals with their right foot.

Recently, the importance of sudden vehicle acceleration accidents has been receiving attention. Investigation results showed that most of the causes of sudden acceleration were due to driver negligence, but the possibility of vehicle defects cannot be ruled out.

However, in the case of presumed sudden acceleration accidents, many drivers panic at the moment of the accident, and due to inexperience in driving or in an urgent situation, the driver confuses the accelerator pedal and the brake pedal and presses the accelerator pedal strongly, resulting in most accidents resulting in sudden acceleration. Occupy

In addition, the number of elderly drivers, which has been increasing recently, is also increasing in the number of accidents that occur due to incorrectly pressing the accelerator and brake pedals due to decreased cognitive function.

Likewise, in the case of a misoperation in which the driver determines that he or she is stepping on the brake pedal and mistakenly steps on the accelerator pedal, the accelerator pedal is stepped on with a very large force, causing sudden acceleration, resulting in a presumed sudden acceleration accident that results in casualties and property damage to the driver or passengers. Most cases occur due to driver misoperation.

In addition, when a sudden acceleration accident occurs while the accelerator pedal is pressed due to driver misoperation, an additional sudden acceleration phenomenon occurs when the driver continues to press the accelerator pedal due to the impact or when the accelerator pedal is forcibly pressed. There is a problem in that car accidents occur and in such cases, large-scale accidents result in many casualties and property damage.

An electric vehicle is a vehicle that runs on electricity as a power source, and an internal combustion engine vehicle is a vehicle that runs by burning fossil fuels such as gasoline or diesel to supply mechanical power according to the operation of the engine.

In particular, recent developments in automobile technology have led to an explosive expansion in the spread of electric vehicles, and most high-power vehicles and luxury vehicles such as electric vehicles are equipped with advanced driver assistance systems (ADAS).

Autonomous driving refers to driving to a given destination on its own by recognizing the surrounding environment, judging the driving situation, and controlling the vehicle without driver intervention.

An autonomous vehicle refers to a vehicle that can drive without driver intervention based on sensor data detected from various sensors installed in the vehicle (LiDAR, Radar, GPS, camera sensor, ultrasonic sensor, etc.). Much research is underway to commercialize these self-driving cars.

As such, the functions and performance of automobiles, including not only internal combustion engine vehicles but also electric vehicles and autonomous vehicles, are continuously improving, but accidents involving elderly drivers are continuously increasing, and sudden acceleration accidents due to driver misoperation are also rapidly increasing, and even Even in the case of self-driving cars, sudden acceleration accidents due to malfunctions, etc., occur.

In particular, as traffic laws are applied more strictly to places such as child protection zones, most serious accidents that occur in child protection zones, alleys, and parking lots are caused by driver negligence, such as incorrect operation of the accelerator pedal.

Moreover, in special locations such as child protection zones and parking lots, the accelerator pedal is operated at the moment when the brake pedal must be operated while driving slowly, and the panicked driver mistakes the accelerator pedal for the brake pedal and presses harder on the accelerator pedal, resulting in large-scale casualties and property damage. There are problems that arise.

As such, there is an urgent need to develop accident prevention devices and accident prevention methods through sudden acceleration due to driver misoperation or autonomous vehicle malfunction, taking into account cases where vehicles are located in specific locations such as child protection areas and parking lots.

As shown in Figures 1 and 2, the accident prevention device 1 through output control according to the vehicle location according to the present invention includes a position detection module 100, an operation module 200, a sensing module 300, and a control Includes module 400.

The location detection module 100 detects the current location of the vehicle using the navigation map and GPS mounted on the vehicle.

The operation module 200 is operated by the driver to accelerate and drive the vehicle. As shown in Figures 3 and 4, the operation module of the accident prevention device through output control according to the vehicle position according to the present invention can be used in both organ type and pendant type.

The sensing module 300 is provided with a first sensor unit 310 and a second sensor unit 320 that are disposed in the operation module and sense an electrical signal according to the amount of light of the operation module.

That is, both the first sensor unit and the second sensor unit of the sensing module are preferably composed of an accelerator pedal position sensor (APS, Accelerator Position Sensor) and convert the amount of stepping according to the operation of the operation module, which is the driver's accelerator pedal, into an electrical signal. It performs the function of conveying.

Although not necessarily limited to this, the first sensor unit of the sensing module of the accident prevention device through output control according to the vehicle location according to the present invention is the main sensor that senses the amount of stepping by the driver's operation of the operation module, and the second sensor unit is the main sensor unit. 1 Performs the function of monitoring the sensor unit.

The control module 400 controls the output of the throttle valve motor unit that controls the opening amount of the throttle valve of an internal combustion engine vehicle or the drive motor of an electric vehicle. The electrical signals from these sensing modules are transmitted to the vehicle control unit, VCU (Vehicle Control Unit) or ECU (Engine Control Unit), and control the opening amount of the throttle valve of an internal combustion engine vehicle or the output of the drive motor of an electric vehicle through the throttle valve motor unit. Control.

This control module converts the electrical signal according to the amount of stepping on the operation module, which is sensed by the sensing module in real time according to the driver's operation, into a percentage, and the converted percentage and the current position detected by the position detection module of the vehicle correspond to the determined position. Depending on the operation time and operation time of the operation module, the output of the throttle valve motor part is limited or the current applied to the drive motor is blocked to prevent sudden acceleration of the vehicle.

As shown in Figure 2, the control module 400 of the accident prevention device 1 through output control according to vehicle location according to the present invention includes a communication module 410, a database module 420, a decision module 430, It includes a confirmation module 440, an operation module 450, a comparison module 460, a processing module 470, and a return module 480.

The communication module 410 communicates with the position detection module, operation module, and sensing module wired or remotely through a network. This network refers to a connection structure that allows information exchange between each node, such as a location detection module, manipulation module, sensing module, and/or control module. An example of such a network is the 3rd Generation Partnership Project (3GPP) network. , LTE (Long Term Evolution) network, WIMAX (World Interoperability for Microwave Access) network, Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal) Area Network, Bluetooth network, satellite broadcasting network, analog broadcasting network, DMB (Digital Multimedia Broadcasting) network, etc. are included, but are not limited to these.

The database module 420 converts the electrical signal according to the amount of stepping on the operation module sensed by the sensing module in real time according to the driver's operation into a percentage, and determines the converted percentage and the current position of the vehicle detected by the position detection module. Data is stored to prevent sudden acceleration of the vehicle by limiting the output of the throttle valve motor part or blocking the current applied to the drive motor depending on the operation time of the operation module.

As shown in Figure 2, the database module 420 of the control module 400 of the accident prevention device 1 through output control according to the vehicle location according to the present invention includes a reference data storage unit 421 and a sensor data storage unit. (422), and a location data storage unit 423.

These database modules may be various storage devices such as ROM, RAM, EPROM, flash drive, hard drive, etc., or may be web storage that performs the storage function of the database module on the Internet.

The reference data storage unit 421 converts the electrical signal according to the amount of stepping on the operation module, which is sensed by the sensing module in real time according to the driver's operation, into a percentage, and calculates the converted percentage and the current position detected by the position detection module. Depending on whether it corresponds to the decision position and the operation time of the operation module, data on the reference percentage, reference time, and return time are provided to prevent sudden acceleration of the vehicle by limiting the output of the throttle valve motor part or blocking the current applied to the drive motor. Save.

Specifically, the reference percentage is set to 90%, the reference time is set to 0.45 seconds or more to 1.8 seconds or less, and the recovery time is set to 0.5 seconds.

As shown in Figure 6, the return time takes 0.4 seconds for a man in his 30s when the operation module, which is the accelerator pedal, is intentionally operated suddenly from 0% to 100% assuming an emergency situation, so the return time is within the safety ratio. Considering this, it was set to 0.5 seconds. If the return time is less than 0.5 seconds, sudden acceleration is possible, but the risk of sudden acceleration still exists, reducing safety and reliability. If it exceeds 0.5 seconds, too much time must be waited, causing inconvenience to the driver and deteriorating the driving environment. To complicate matters, there are problems that lead to other risks in road conditions.

As shown in Figure 7, the analysis results of accident vehicle data that occurred when leaving from a parking lot on a narrow road or residential road, which is a narrow road where the sidewalk and the roadway are not clearly distinguished, show that the operation module, which is the accelerator pedal, is operated from 0% to 99%. It took seconds, and as shown in Figure 8, the analysis results of the accident vehicle data that occurred when leaving the apartment underground parking lot show that it took 1.5 seconds to operate the control module, which is the accelerator pedal, from 0% to 99%.

If the standard time is less than 0.45 seconds, sudden start operation is possible within 0.4 seconds as shown in Figure 5, so the risk of sudden start still exists, reducing safety and reliability, and if it exceeds 1.8 seconds, too much time must be waited. There are problems that cause inconvenience to drivers, complicate the driving environment, and cause other risks in road conditions.

However, these reference data are automatically generated by performing machine learning by selecting one or more of Supervised Learning, Unsupervised Learning, or Reinforcement Learning. It is continuously modified and reset according to changes in the type and shape of the vehicle, the driver's driving tendency, and the driver of the vehicle.

The sensor data storage unit 422 stores data on the moving distance of the manipulation module, the operating input voltage of the first sensor unit and the second sensor unit, the initial output voltage value, and the final output voltage value.

In other words, data on the movement distance (stroke) of the operation module, the operation input voltage of the first and second sensor units, and the initial and final values of the output voltage are stored in the sensor data storage to meet the operating conditions of the operation module. Save it to comply with .

As shown in Figure 9, the operating input voltage of the first sensor unit is 5 volts (V), the output voltage is set to 0.2 volts (V) or more and 4.5 volts (V) or less, and the operating input voltage of the second sensor unit is 5 volts (V). The output voltage is 0.1 volts (V) or more and 2.45 volts (V) or less, and is set to generate approximately 1/2 the output of the first sensor unit.

If the output voltage of the first sensor unit is less than 0.2 volts (V) or more than 4.5 volts (V), the first sensor unit cannot detect the amount of stepping caused by the operation of the operation module, which is the driver's accelerator pedal, and the detection range There is a problem in that the reliability and stability of the sensing module decreases as the malfunction rate increases.

In addition, if the second sensor unit does not generate 1/2 the output of the first sensor unit, error judgment due to malfunction of the first sensor unit cannot be made quickly and accurately, resulting in failure or damage to the electric vehicle or internal combustion engine vehicle and sensing damage. There is a problem that a lot of cost and time are consumed in the installation and maintenance of modules.

If the output voltage of the second sensor unit is less than 0.1 volts (V) or more than 2.45 volts (V), the second sensor unit can detect the amount of stepping by the driver's operation of the operation module, which is the accelerator pedal, with the first sensor unit. At this time, there is a problem that the presence or absence of an error depending on whether the first sensor unit is operating normally cannot be detected, and the occurrence rate of malfunctions increases depending on the detection range, thereby reducing the reliability and stability of the sensing module.

Additionally, the movement distance (stroke, mm) of the manipulation module is set to be 0 mm or more and 50 mm or less.

If the moving distance of the operating module is less than 0 mm, pressurization does not occur as the operating module moves and mechanical design is not possible, resulting in manufacturing difficulties. In addition, if the moving distance of the operating module exceeds 50 mm, not only is it difficult for the driver to operate, but the size of the operating module becomes too large, reducing space utilization and increasing the incidence of erroneous operation as the moving distance increases, which reduces reliability and stability. There is a problem.

In addition, these sensing data are automatically processed by performing machine learning by selecting one or more of Supervised Learning, Unsupervised Learning, or Reinforcement Learning. It is continuously modified and stored in the sensing data storage in a reset state according to changes in the type and shape of the vehicle, the driver's driving tendency, and the driver of the vehicle.

The location data storage unit 423 stores location data according to the location of the road when driving an internal combustion engine vehicle or electric vehicle.

At this time, through image recognition using big data from the location data storage, it is automatically determined whether the location corresponds to an on-street parking lot, a parking lot in a building, a narrow road where the sidewalk and the roadway are not clearly distinguished, or a child protection zone. Then, select one or two or more of supervised learning, unsupervised learning, or reinforcement learning, and automatically classify, decide, and store them through machine learning.

The decision module 430 determines whether the current location of the vehicle is a location where operation of the sudden acceleration prevention mode of the vehicle is required according to the data stored in the database module and the location detection module.

In addition, in the decision module of the accident prevention device 1 through output control according to the vehicle location according to the present invention, the decision location where the sudden acceleration prevention mode of the vehicle is required is not clearly distinguished between the on-street parking lot, the parking lot in the building, and the sidewalk and roadway. It is limited to narrow roads (back roads or residential roads) or children's protection areas.

In other words, accelerating to drive while the vehicle is stopped or parked in an on-street parking lot, a building parking lot, a narrow road (side road or residential road) where the sidewalk and the roadway are not clearly distinguished, or a decision location corresponding to a child protection zone. When attempting to drive the vehicle by manipulating the pedal-in operation module, if a child suddenly jumps out of the blind spot, the sudden acceleration prevention mode is automatically activated when the first, second, and third conditions are met, preventing fatalities and accidents due to sudden acceleration. By preventing property damage in advance, you can protect the safety and life of drivers, pedestrians, and passers-by.

The confirmation module 440 checks changes in the operation module by the operation module and the sensing module when the sudden acceleration prevention mode of the vehicle is required to operate as a result of the decision of the decision module. In other words, the confirmation module checks the amount and rate of change of the manipulation module through the manipulation module and sensing module.

When a change in the operation module is confirmed as a result of the confirmation module, the operation module 450 calculates and converts the data stored in the database module and the electrical signal according to the amount of stepping on the operation module sensed in real time by the sensing module into a percentage.

That is, as shown in FIG. 10, the calculation module determines the initial value of the sensor output voltage of the first sensor unit and the second sensor unit according to the moving distance of the operation module based on the data stored in the sensor data storage unit and the sensing result of the sensing module. Calculate the percentage as linearly proportional to the final value.

Specifically, when the moving distance of the manipulation module is 0 mm, the output voltage of the first sensor part is 0.2 volts (V) and the output voltage of the second sensor part is 0.1 volts (V), the percentage becomes 0%, and the percentage of the manipulation module is 0%. When the moving distance is 10 mm and the output voltage of the first sensor unit is 1.06 volts (V) and the output voltage of the second sensor unit is 0.57 volts (V), the percentage becomes 20%.

If the moving distance of the manipulation module is 2.5 mm, the output voltage of the first sensor unit is 0.415 volts (V) and the output voltage of the second sensor unit is 0.22 volts (V), the percentage is 5% through linear proportion. It is calculated.

According to the calculation results, the calculation module converts the electrical signal according to the amount of stepping on the operation module into a linear proportion as a percentage.

The comparison module 460 compares the percentage converted through the calculation module and the real-time operation time of the manipulation module with the standard percentage and standard time stored in the database unit. In other words, the comparison module operates in real time until the percentage converted by linear proportion to a percentage increases from 0% to over 90%, which is the standard percentage stored in the standard data storage, by converting the electric signal according to the amount of stepping on the operation module by the calculation module. Compare whether the time falls within the standard time stored in the standard data storage unit, which is 0.45 seconds or more and 1.8 seconds or less.

If the real-time operation time required for the converted percentage of the comparison result of the comparison module to exceed the standard percentage is within the standard time, the processing module 470 determines it to be a misoperation and processes it by converting the step amount of the manipulation module to 0%. .

In other words, if the real-time operation time required for the converted percentage as a result of the comparison of the comparison module to exceed the standard percentage of 0% to 90% is within the standard time of 0.45 seconds or more and 1.8 seconds or less, the processing module is operated due to driver error. In the case of an internal combustion engine vehicle, the sensing value of the sensing module for the percentage of the electric signal according to the amount of stepping on the operation module is converted to 0% to limit the output of the throttle valve motor part, or in the case of an electric vehicle, the current is cut off to the drive motor to drive the vehicle. It suppresses the motor's output and switches it to regenerative braking. Similarly, as a result of the comparison of the comparison module, the real-time operation time required for the converted percentage to exceed the standard percentage of 0% to 90% is less than the standard time of 0.45 seconds or exceeds 1.8 seconds, or the converted percentage exceeds the standard percentage of 90%. If it is not exceeded, it is judged as normal driving and the sudden acceleration prevention mode is not activated.

The return module 480 detects the driver's erroneous operation when the real-time operation time required for the converted percentage as a result of comparison of the comparison module to exceed the standard percentage of 0% to 90% is within the standard time of 0.45 seconds or more and 1.8 seconds or less. If the converted percentage of the operation module is 0% and the converted percentage remains at 0% for longer than the return time of 0.5 seconds while the sudden acceleration prevention mode is activated, the sudden acceleration prevention mode is released and normal driving is resumed. reinstate

Although not shown in the drawing, the control module of the accident prevention device through output control according to vehicle location according to the present invention may further include a selection module and a display module.

The selection module switches on the vehicle's sudden acceleration prevention mode when the current location of the vehicle detected by the location detection module corresponds to one of the following: an on-street parking lot, a parking lot in a building, a narrow road where the sidewalk and the roadway are not clearly distinguished, or a child protection zone. Firstly, it is determined whether the operation is in a decision position where operation is required, and secondarily, changes in the operation module are checked, and the electrical signal according to the amount of stepping on the operation module sensed by the sensing module in real time according to the driver's operation is converted into a percentage. The third-converted percentage and the real-time operation time of the operation module are compared with the standard percentage and standard time stored in the database. If all three are met, it is judged to be a driver's erroneous operation, and in the case of an internal combustion engine vehicle, the operation module is not stepped on. It limits the output of the throttle valve motor unit by converting the sensing value of the sensing module for the percentage of electric signal according to the amount of force to 0%, and in the case of an electric vehicle, blocks the current to the drive motor to suppress the output of the drive motor and simultaneously regenerate it. It switches to a braking state and performs a function that allows the driver to select and activate whether to prevent sudden acceleration of an internal combustion engine vehicle or electric vehicle that occurs when the driver presses the accelerator pedal instead of the brake pedal due to driver error.

Specifically, the selection module is formed in the form of a button on the display module, instrument panel, or control panel of the vehicle. When the driver performs the automatic sudden acceleration prevention mode function by operating the button, the current location of the vehicle detected by the position detection module is displayed in the street parking lot or inside the building. If you are in one of the following areas: a parking lot, a narrow road where the sidewalk and the roadway are not clearly distinguished, or a child protection zone, it is first determined whether the vehicle's sudden acceleration prevention mode needs to be activated, and secondarily, the operation module is changed. After checking and converting the electrical signal according to the amount of stepping on the operation module sensed by the sensing module in real time according to the driver's operation into a percentage, the thirdly converted percentage and the real-time operation time of the operation module are stored in the database. Comparing the percentage and the standard time, if all three are met, it is judged to be a driver's misoperation. In the case of an internal combustion engine vehicle, the sensing value of the sensing module for the percentage of the electric signal according to the amount of pressure on the operation module is converted to 0% and the throttle is activated. It limits the output of the valve motor unit and, in the case of electric vehicles, cuts off the current to the drive motor to suppress the output of the drive motor and at the same time switches to a regenerative braking state, which causes internal combustion that occurs when the driver incorrectly operates the accelerator pedal instead of the brake pedal. Prevent sudden acceleration of locomotives or electric vehicles.

In this way, as the driver arbitrarily selects whether to activate the automatic sudden acceleration prevention mode according to need, safety according to the driver's vehicle operation status can be maximized and driver convenience can be improved.

The display module displays the results of the database module, decision module, confirmation module, calculation module, comparison module, processing module, return module, and selection module in real time to provide visual information to the driver and improve driver convenience.

These display modules include liquid crystal display (LCD), thin film transistor-liquid crystal display (TFT LCD), organic light-emitting diode (OLED), and flexible display. , a 3D display, or an e-ink display.

In each step, the specific operating process, operating principle, configuration, or content of the device are the same as the accident prevention device through output control according to the vehicle location in the specification of the present invention, and hereinafter, referring to FIGS. 3 to 11, the device according to the vehicle location This section focuses on the unique features of accident prevention methods through output control.

According to the driver's operation, the electric signal according to the amount of stepping on the operation module sensed in real time by the driver's operation is converted into a percentage, and the converted percentage and the current position of the vehicle detected by the position detection module correspond to the determined position and the operation module Depending on the operation time, the output of the throttle valve motor part is limited or the current applied to the drive motor is blocked to prevent sudden acceleration of the vehicle.

After the data storage step (S1), the current location of the vehicle is detected using the navigation map and GPS mounted on the vehicle.

After the location detection step (S2), it is determined whether the current location of the vehicle is a location that requires operation of the vehicle's sudden acceleration prevention mode according to the pre-stored data and the vehicle's location detection result.

After the decision step (S3), if it is necessary to operate the vehicle's sudden acceleration prevention mode as a result of the decision, changes in the operation module are checked by the operation module and sensing module.

After the confirmation step (S4), when a change in the manipulation module is confirmed as a result of the confirmation, the electric signal according to the amount of stepping on the manipulation module sensed in real time by the sensing module is calculated and converted into a percentage based on the previously stored data.

After the calculation step (S5), the converted percentage and real-time operation time of the operation module are compared with the previously stored reference percentage and reference time.

After the comparison step (S6), if the real-time operation time required for the converted percentage as a result of the comparison to exceed the standard percentage of 0% to 90% is within the standard time of 0.5 seconds or more and 1.8 seconds or less, the driver's erroneous operation may occur. In the case of an internal combustion engine vehicle, the sensing value of the sensing module for the percentage of the electric signal according to the amount of stepping on the operation module is converted to 0% to limit the output of the throttle valve motor part, or in the case of an electric vehicle, the current is cut off to the drive motor to drive the vehicle. It suppresses the motor output and switches to regenerative braking state at the same time.

After the processing step (S7), if the converted percentage of the operation module is 0% and the converted percentage remains at 0% for longer than the return time of 0.5 seconds, the sudden acceleration prevention mode is released and normal driving is returned.

As such, the accident prevention device and accident prevention method through output control according to the vehicle location according to the present invention detects the current location of the vehicle by the position detection module in an on-street parking lot, a parking lot in a building, and a narrow road where the sidewalk and the roadway are not clearly distinguished. If the vehicle is located in one of the road or child protection zones, it is first determined whether the car is in a position where sudden acceleration prevention mode needs to be activated, and secondarily, changes in the operation module are checked and sensed in real time according to the driver's operation. After converting the electrical signal according to the amount of stepping on the operation module sensed by the module into a percentage, the thirdly converted percentage and the real-time operation time of the operation module are compared with the standard percentage and standard time stored in the database, and all three are applicable. In this case, it is judged to be a driver's misoperation, and in the case of an internal combustion engine vehicle, the sensing value of the sensing module for the percentage of the electric signal according to the amount of pressure on the operation module is converted to 0% to limit the output of the throttle valve motor part. In the case of an electric vehicle, the sensing value of the sensing module is converted to 0%. By blocking the current to the drive motor, it suppresses the output of the drive motor and at the same time switches to a regenerative braking state to prevent sudden acceleration of an internal combustion engine or electric vehicle that occurs when the driver presses the accelerator pedal instead of the brake pedal due to driver misoperation. It protects the occupants and protects the lives and property of the public by preventing secondary sudden acceleration accidents that occur when the accelerator pedal is pressed more strongly due to the impact when an accident occurs while the operation module, which is the accelerator pedal, is pressed. .
