Description

Driving suitability evaluation system and method using a dummy thrust device {SYSTEM, METHOD AND COMPUTER PROGRAM FOR PERFORMING EVALUATION OF DRIVING FITNESS USING DUMMY DEVICE}

The present invention relates to a technology for precisely evaluating the effect of physical decline in elderly people on driving. More specifically, the present invention uses a dummy unexpected device to analyze the time it takes for the driver to recognize the dummy unexpected and brake the vehicle when a dummy unexpected appears, in order to minimize data distortion depending on the vehicle's speed. It is about a technology that determines the time of appearance of a dummy accident device and automatically analyzes the driving suitability of elderly drivers through this.

The existing driver's license test is designed to evaluate the minimum knowledge for driving, ability to comply with laws, and ability to operate and steer a vehicle. It evaluates whether the driver has the ability to exceed the minimum standard for driving.

The driver's license test consists of a written test, intestinal function test, and road driving test. The driver's license test is conducted in the following order: written test, intestinal function test, and road driving test. A passing certificate is issued only when all tests are passed.

Among these, the internal function test evaluates the test taker's driving ability by installing a terrain feature similar to an actual road at the driver's license test site. The scoring method of the internal function test is that if it is higher than a predetermined standard evaluation value, it is processed as passing.

In the case of elderly drivers holding a driver's license, the evaluation structure based on the existing intestinal function test (i.e., a structure that determines pass or fail based on predetermined standard evaluation values) cannot accurately evaluate driving suitability due to physical decline. there is a problem.

1 is a configuration diagram of a driving suitability evaluation system according to an embodiment of the present invention.

Referring to FIG. 1 , the driving suitability evaluation system may include a driving evaluation system 100, a vehicle 110, and a dummy crash device 120. However, since the driving suitability evaluation system of FIG. 1 is only one embodiment of the present invention, the present invention is not limited to FIG. 1, and may be configured differently from FIG. 1 according to various embodiments of the present invention. .

The driving evaluation system 100 may collect driving data of the vehicle 110 generated while the vehicle 110 with the driver in it is driving within the test site.

The driving evaluation system 100 may determine the appearance point of the dummy explosion device 120 installed in the test site based on the driving data of the vehicle 110.

The driving evaluation system 100 is based on the distance between the position of the vehicle 110 and the position of the dummy abrupt device 120 derived from the driving data of the vehicle 110, and the derived speed of the vehicle 110. The appearance point of (120) can be determined.

The driving evaluation system 100 may transmit an appearance signal to the dummy unexpected device 120 based on the determined appearance time of the dummy unexpected device 120.

The dummy explosion device 120 may appear in a predetermined dummy appearance section within the test site based on the appearance signal received from the driving evaluation system 100. This dummy emergency device 120 is a device for evaluating the driver's perception, reaction, and operation in an emergency situation.

When the dummy sudden device 120 appears, the driver recognizes the appearance of the dummy unexpected device 120 and quickly applies the brakes. At this time, the driving evaluation system 100 can evaluate how quickly the driver safely stops the vehicle 110 without colliding with the dummy crash device 120.

The driving evaluation system 100 performs a driving suitability evaluation on the driver based on the driving data generated from the vehicle 110 in a situation where the dummy unexpected device 120 appears based on the appearance signal of the dummy unexpected device 120. can do.

Hereinafter, the operation of each component of the driving suitability evaluation system of FIG. 1 will be described in more detail.

Figure 2 is a block diagram of the driving evaluation system 100 shown in Figure 1, according to an embodiment of the present invention.

Referring to FIG. 2, the driving evaluation system 100 includes a collection unit 200, a driving suitability index calculation unit 210, an appearance timing determination unit 220, a transmission unit 230, a driving evaluation unit 240, and a driving evaluation unit 240. It may include an information provision unit 250 and a collision prevention unit 260. However, the driving evaluation system 100 shown in FIG. 2 is only one implementation example of the present invention, and various modifications are possible based on the components shown in FIG. 2.

Hereinafter, FIG. 2 will be described with reference to FIGS. 3 to 5B.

The present invention seeks to analyze the impact or risk of overall physical decline due to aging (deterioration of visual acuity, increased cognitive reaction time, lack of agility and braking power, etc.) on actual driving.

In order to analyze the impact of physical function decline due to aging on driving while the driver is driving the vehicle, the collection unit 200 may collect experimental data from each of the general driver experimental group and the elderly driver experimental group recruited by age. Here, the experimental data may be derived from driving data related to the course where the dummy explosive device 120 appears in the test site. The experimental data may include data for deriving the driver's cognitive reaction time, idle time, braking time, etc. according to the pile accident situation under the same conditions. Here, the cognitive reaction time refers to the time required from the appearance of the dummy sudden device 120 to the time the driver applies the brakes of the vehicle, and the idle time refers to the time required for the vehicle to completely stop from the time the driver applies the brakes of the vehicle. It refers to the time required to stop, and braking time refers to the sum of cognitive reaction time and idle time.

The driving suitability index calculation unit 210 derives a standard distribution (e.g., a standard distribution for each of the cognitive reaction time, idle time, and braking time of the general driver experimental group) for the experimental data of the general driver experimental group, and the experimental data of the elderly driver experimental group. A standard distribution for the data (e.g., a standard distribution for each of the cognitive reaction time, idle time, and braking time of the elderly driver experimental group) can be derived.

The driving suitability index calculation unit 210 compares the standard distribution for the experimental data of the general driver experimental group and the standard distribution for the experimental data of the elderly driver experimental group to derive a difference value, and calculates the difference between the elderly driver and the general driver based on the difference value. Driving suitability evaluation index information can be derived.

For example, the driving suitability index calculation unit 210 compares the standard distribution for the cognitive reaction time of the general driver experimental group and the standard distribution for the cognitive reaction time of the elderly driver experimental group to derive the first difference value, and the first difference Based on the value, the first driving suitability evaluation index information between older drivers and regular drivers regarding cognitive reaction time (for example, older drivers have longer daily reaction times than regular drivers) can be derived.

For example, the driving suitability index calculation unit 210 derives a second difference value by comparing the standard distribution for the idle time of the general driver experimental group and the standard distribution for the idle time of the elderly driver experimental group, and adds Based on this, the second driving suitability evaluation index information between older drivers and regular drivers regarding idle time (for example, older drivers have longer idle times than regular drivers) can be derived.

For example, the driving suitability index calculation unit 210 compares the standard distribution for the braking time of the general driver experimental group and the standard distribution for the braking time of the elderly driver experimental group to derive a third difference value, and adds the third difference value to the third difference value. Based on this, the third driving suitability evaluation index information between older drivers and regular drivers regarding braking time (for example, older drivers have longer braking times than regular drivers) can be derived.

The collection unit 200 may collect driving data generated while the vehicle 110 with the actual driver on board drives within the test site.

For example, referring to FIG. 3, the collection unit 200 collects information about the driver's vehicle 110 driving on a plurality of driving courses (301, 303, 305, 307, 309, 311, 313) existing in the test site. Driving data can be collected from the vehicle 110 in real time.

For example, among a plurality of driving courses (301, 303, 305, 307, 309, 311, 313) in the test site, the vehicle 110 is driven on a driving course determined based on the location of the vehicle 110 in which the driver rides. In this case, the collection unit 200 may collect driving data for the vehicle 110 driving the determined driving course in real time from the vehicle 110 .

For example, in order to evaluate the driver's situational awareness and response ability to the dummy unexpected device 120 that appears in the dummy appearance course 313, the collection unit 200 detects the driver driving in the dummy appearance course 313. Driving data for the vehicle 110 can be collected in real time from the vehicle 110.

The appearance time determination unit 220 may derive the location and speed of the vehicle 110 based on the driving data of the vehicle 110.

The appearance point determination unit 220 may derive the distance between the derived location of the vehicle 110 and the location of the dummy explosion device 120. Here, referring to FIG. 3, the dummy unexpected device 120 is a traffic obstacle that appears at a predetermined location on the dummy appearance course 313 within the test site.

On the other hand, assuming that the appearance time of the dummy sudden device 120 is constant at a preset time regardless of the speed of the vehicle 110, when the driver's vehicle 110 is traveling at a low speed, the dummy unexpected device 120 While the driver can easily respond to the appearance of the vehicle 110 at high speeds, it is relatively difficult for the driver to respond to the appearance of the dummy unexpected device 120, so the driver's perception, reaction, and operation in an unexpected situation. The reliability of the evaluation may be lost. In order to solve this problem, the present invention variably controls the appearance point of the dummy explosive device 120 based on the distance between the position of the vehicle 110 and the position of the dummy explosive device 120 and the speed of the vehicle 110. can do.

The appearance time determination unit 220 may determine the appearance time of the dummy explosion device 120 installed in the test site based on the driving data of the vehicle 110.

For example, referring to FIG. 3, the appearance time determination unit 220 determines the distance between the position of the vehicle 110 and the position of the dummy explosion device 120 derived from the driving data of the vehicle 110, and the derived vehicle Based on the speed of 110, the appearance point of the dummy explosion device 120 in the dummy appearance course 313 can be determined.

The appearance time determination unit 220 may derive the idle distance for the vehicle 110 based on the derived speed and idle time of the vehicle 110.

The princess distance is the distance traveled by the vehicle 110 until the driver recognizes a traffic obstacle (for example, the dummy crash device 120) and applies the brakes until the brakes are activated. This princess distance can be calculated through [Equation 1].

[Equation 1]

Here, s is the idle distance, v is the vehicle speed at the point when the driver applies the brake, and t is the idle time.

Here, the idle time is the driver's reaction time experimentally derived based on the driver's perception of traffic obstacles.

Referring to [Equation 1], the idle distance increases linearly as the speed of the vehicle increases. In other words, the idle distance is proportional to the speed at which the vehicle is running and the driver's reaction time (i.e., idle time).

The appearance time determination unit 220 calculates the acceleration of the vehicle 110 based on at least one of the weight of the vehicle 110, brake performance, and the degree of friction between the ground of the test site and the tires of the vehicle 110, and the derived vehicle 110 The braking distance for the vehicle 110 can be derived based on the speed of the vehicle 110 and the acceleration of the vehicle 110.

The braking distance is the distance traveled until the vehicle 110 comes to a complete stop after the brakes of the vehicle 110 are activated (i.e., after braking begins). This braking distance follows the constant acceleration formula (Equation 2), the final speed of the vehicle 110 is 0, and the direction of acceleration due to the brake is opposite to the direction of travel of the vehicle 110, so the braking distance is [Equation 3] ] can be calculated through.

[Equation 2]

Here, v is the vehicle's speed, a is the acceleration, and s is the braking distance.

[Equation 3]

Here, s is the braking distance.

Referring to [Equation 3], the braking distance is proportional to the square of the initial speed at which the vehicle was running and inversely proportional to the acceleration. At this time, acceleration varies depending on the weight of the vehicle, brake performance, and the degree of friction between the ground and tires.

The appearance time determination unit 220 may derive a stopping distance for the vehicle 110 based on the idle distance for the vehicle 110 and the braking distance for the vehicle 110. Here, the stopping distance refers to the distance traveled until the vehicle 110 comes to a complete stop after the driver recognizes a traffic obstacle and applies the brakes to start braking. This stopping distance can be calculated through [Equation 4].

[Equation 4]

Stopping Distance = Princess Distance + Braking Distance

The appearance time determination unit 220 determines the appearance time of the dummy unexpected device 120 based on the distance between the derived position of the vehicle 110 and the position of the dummy unexpected device 120 and the stopping distance for the vehicle 110. You can decide.

For example, the appearance time determination unit 220 determines the time when the distance between the derived position of the vehicle 110 and the position of the dummy sudden device 120 becomes shorter or equal to the stopping distance for the vehicle 110. It can be determined by the appearance time of (120).

For another example, the appearance time determination unit 220 may reflect a preset compensation value on the appearance time of the dummy unexpected device 120 to make a final decision on the appearance time of the dummy unexpected device 120.

In the case of elderly drivers, the reaction time to traffic obstacles is slower than that of general drivers, so the stopping distance of elderly drivers may be longer than that of general drivers. In order to reflect this at the appearance time, the appearance time determination unit 210 delays the appearance time of the dummy unexpected device 120 from the existing appearance time by reflecting the compensation value (e.g., 0.5 s) to the existing appearance time. You can decide to lose.

The transmission unit 230 may transmit an appearance signal to the dummy unexpected device 120 based on the determined appearance time of the dummy unexpected device 120. The dummy unexpected device 120 may appear in a predetermined dummy appearance section 40 within the test site based on the appearance time of the dummy unexpected device 120. The dummy explosion device 120 may appear across a pre-designated dummy appearance section 40 on the road within the test site.

When the dummy sudden device 120 appears, the driver recognizes the appearance of the dummy unexpected device 120 and quickly applies the brakes. At this time, the driving evaluation unit 230 may evaluate how quickly the driver safely stops the vehicle 110 without colliding with the dummy crash device 120.

Specifically, the driving evaluation unit 230 determines the driving suitability of the driver based on the driving data generated from the vehicle 110 in a situation where the dummy unexpected device 120 appears based on the appearance signal of the dummy unexpected device 120. Evaluation can be performed.

For example, the driving evaluation unit 230 determines safe driving ability items according to accident risk, unexpected situation recognition, and response ability items based on driving data generated from the vehicle 110 in a situation where a dummy unexpected device 120 appears. A driver's driving suitability evaluation can be performed.

For example, the driving evaluation unit 230 may evaluate whether there is a collision between the driver's vehicle 110 and the dummy unexpected device 120 when the dummy unexpected device 120 appears. That is, the driving evaluation unit 230 scores the safe driving ability item as 0 when the driver's vehicle 110 collides with the dummy crash device 120, and the driver's vehicle 110 collides with the dummy crash device 120. If there is no collision with the device 120, the safe driving ability item can be scored as 100 points.

For example, the driving evaluation unit 230 measures the time elapsed from the time the dummy emergency device 120 appears in front of the driver's vehicle 110 to the time the driver applies the brake, and based on the measured time Situational awareness items (i.e. cognitive reaction time) can be evaluated.

For example, the driving evaluation unit 230 evaluates the driver's ability to clearly recognize the situation and respond quickly according to the appearance of the dummy unexpected device 120. The time taken to stop (i.e., the speed of the vehicle 110 = 0) can be measured, and coping ability items can be evaluated based on the measured time.

For example, the driving evaluation unit 230 measures the change in deceleration per hour (average) from the appearance of the dummy sudden device 120 until the driver applies the brake and the vehicle 110 completely stops, and the measured The ability to cope with unexpected situations can be evaluated based on the amount of change in deceleration per hour.

For example, the driving evaluation unit 230 determines whether the vehicle 110 has stopped in the dummy appearance section within a preset time from the time the appearance signal of the dummy unexpected device 120 is transmitted to the dummy unexpected device 120 or whether the vehicle ( The index of the driver's safe driving ability items can be scored based on whether 110) collided with the dummy explosion device 120.

For example, the driving evaluation unit 230 determines the cognitive reaction time at which the driver recognizes the appearance of the dummy unexpected device 120 based on driving data generated from the vehicle 110 in a situation where the dummy unexpected device 120 appears. By measuring and measuring the change in deceleration per hour of the vehicle 110, the index of the driver's situation awareness and coping ability items can be scored.

The driving evaluation unit 230 may perform a suitability evaluation on the driver based on a comparison between the driver's driving data and the driving suitability evaluation index information derived by the driving suitability index calculation unit 210.

For example, the driving evaluation unit 230 may evaluate the driver's driving suitability as a good level if the driver's suitability evaluation score is within the top 50% based on comparison between the driver's driving data and driving suitability evaluation indicator information, If the driver's suitability evaluation score is within the median 40%, the driver's suitability for driving can be assessed as average, and if the driver's suitability assessment score is within the bottom 10%, the driver's suitability for driving can be assessed as being at a dangerous level.

When the driver is a general driver, the driving evaluation unit 230 may perform a suitability assessment for the driver based on a comparison between the driver's driving data and a standard distribution for the general driver's test data. For example, the driving evaluation unit 230 may perform a suitability evaluation for the driver based on a comparison result between the cognitive reaction time derived from the driver's driving data and the standard distribution for the cognitive reaction time of general driver experiment data. .

When the driver is an elderly driver, the driving evaluation unit 230 is based on the comparison results between the driver's driving data and the standard distribution for the elderly driver's experimental data, and the comparison results between the driver's driving data and the standard distribution for the general driver's experimental data. This allows you to perform a suitability assessment on the driver.

The driving information provider 250 may provide driving suitability evaluation information and driving guide based on the driving suitability evaluation for the driver.

For example, when the cognitive reaction speed of an elderly driver is significantly reduced and the driving distance is long, the driving information provider 250 only applies to cars equipped with auxiliary devices such as driver assistance systems (ADAS) or emergency braking (AEB). Driving guides may be provided that restrict your ability to drive. Additionally, if the elderly driver's driving suitability is in the bottom 10%, the driving information provider 250 may provide driving guidance, such as encouraging the driver to return the driver's license and restricting driving at night or during rush hour.

For example, the driving evaluation unit 230 may provide a driving guide based on a driving suitability evaluation corresponding to a plurality of items. Here, for example, referring to FIG. 5A, the plurality of items may include items of ability to recognize and respond to unexpected situations and the ability to safely and quickly respond to unexpected situations.

For example, the driving information provider 250 provides the driver with the driver's driving suitability evaluation information and the risk level of the driver's driving ability (FIG. 5b) through a radial chart (FIG. 5a), and provides a driving guide accordingly. can be provided.

For example, the driving information provision unit 250 says, 'The driver's overall driving ability score is 62.5 points, and this score is at the bottom 4% of the average driver's driving ability, so the risk level of driving is at a dangerous level. Driving suitability assessment information and risk level, including 'Please minimize driving yourself considering the risk of traffic accidents', can be provided to drivers.

For example, if the driver is assessed as dangerous in the ability to safely and quickly respond to unexpected situations due to a collision, the driving information provider 250 may indicate that 'the driver's ability to respond to sudden situations while driving is insufficient, and Driving guides can be provided to drivers, including 'Driving slowly and paying attention to the situation ahead/surroundings is necessary as traffic accidents may occur while driving.'

For example, if the driver is assessed as dangerous in the category of ability to recognize and respond to unexpected situations, the driving information provider 250 may say, 'The driver lacks the ability to recognize and respond to various unexpected situations ahead while driving, and must drive slowly to prevent accidents. Driving guides can be provided, including the need for defensive driving habits through driving and risk prediction.

Referring to FIG. 4, the collision prevention unit 260 is configured to detect the vehicle ( It may be determined whether a collision between the vehicle vehicle 110 and the dummy explosive device 120 is expected based on the position and speed of the vehicle 110.

If the vehicle 110 does not stop in the dummy appearance section 40 within a preset time from the time the appearance signal of the dummy unexpected device 120 is transmitted to the dummy unexpected device 120, the collision prevention unit 260 A collision between the vehicle 110 and the dummy explosion device 120 can be prevented based on the position and speed of the vehicle 110.

The collision prevention unit 260 may determine whether the vehicle 110 has entered a collision risk zone based on the speed of the vehicle 110 and the distance between the location of the vehicle 110 and the location of the dummy explosion device 120. Here, the collision risk section may be derived from the speed of the vehicle 110 and the stopping distance for the vehicle 110.

For example, when the stopping distance for the vehicle 110 is 5 m or more and the distance between the location of the vehicle 110 and the location of the dummy crash device 120 is within 5 m, the collision prevention unit 260 is installed on the vehicle 110. ) can be determined to have entered the collision risk zone with the dummy explosion device 120.

If it is determined that the vehicle 110 has entered a collision risk zone, the collision prevention unit 260 may force the vehicle 110 to stop by forcibly applying the brakes and stopping the engine. Through this, the present invention can minimize the impact upon collision between the vehicle 110 and the dummy explosion device 120 and prevent collisions.

When the front sensor (e.g., radar sensor, etc.) of the vehicle 110 detects the dummy explosive device 120, the collision prevention unit 260 determines the speed of the vehicle 110 and the location of the vehicle 110 and the dummy explosive device. Based on the distance between the positions of 120, the expected collision time between the vehicle 110 and the dummy explosion device 120 may be calculated, and the vehicle 110 may be forced to stop according to the calculated expected collision time. Through this, the present invention can minimize the impact or prevent a collision during a collision between the vehicle 110 and the dummy explosion device 120.

For example, when the collision prevention unit 260 determines that the expected collision time between the vehicle 110 and the dummy crash device 120 is less than or equal to a preset threshold, the collision prevention unit 260 forcibly operates the brakes and stops the vehicle 110. (110) can be forced to stop.

Meanwhile, those skilled in the art will know that the collection unit 200, the driving suitability index calculation unit 210, the appearance time determination unit 220, the transmission unit 230, the driving evaluation unit 240, the driving information provision unit 250, and the collision It will be fully understood that each of the prevention units 260 may be implemented separately, or one or more of them may be integrated and implemented.

Figure 6 is a flowchart showing a method of performing a driving suitability evaluation according to an embodiment of the present invention.

Referring to FIG. 6 , in step S601, the driving evaluation system 100 may collect driving data generated while the vehicle 110 with the driver in it drives within the test site.

In step S603, the driving evaluation system 100 may determine the appearance point of the dummy explosion device 120 installed in the test site based on the driving data of the vehicle 110.

In step S605, the driving evaluation system 100 may transmit an appearance signal to the dummy emergency device 120 based on the determined appearance time.

In step S607, the driving evaluation system 100 may check whether the vehicle 110 has stopped in a predetermined dummy appearance section within the test site in a situation where the dummy sudden device 120 has appeared based on the appearance signal.

In step S609, when the vehicle 110 stops in the dummy appearance section within a preset time from when the appearance signal is transmitted, the driving evaluation system 100 detects the A driving suitability evaluation for the driver can be performed based on the generated driving data.

In step S611, if the vehicle 110 does not stop in the dummy appearance section within a preset time from when the appearance signal is transmitted, the driving evaluation system 100 determines the vehicle 110 based on the position and speed of the vehicle 110. It is possible to calculate the risk of collision between and the dummy explosion device 120. At this time, the driving evaluation system 100 may calculate the collision risk based on the speed of the vehicle 110 and the distance between the location of the vehicle 110 and the location of the dummy crash device 120.
