The present invention relates to a safe driving guide system, and more particularly, to a safe driving guide system capable of effectively inducing safe driving by deriving a safety index for the driver's driving behavior.

With the recent increase in the number of vehicle drivers, traffic is becoming more crowded, and the rate of traffic accidents due to the wrong driving habits of drivers is increasing.

Accordingly, there is an increasing need for a safe driving guide system to improve wrong driving habits and violent driving habits causing traffic accidents.

As a result, many countries around the world are making great efforts to develop advanced safe vehicles. Such advanced safety vehicles mean deaths in case of a traffic accident, reduce fatigue of drivers, and are convenient to drive, and the basic concept is to prevent accidents in order to improve the stability of vehicles and to protect pedestrians.

For example, the driver may detect a driver's drowsy driving in a driving state of the vehicle and warn the driver by detecting a deviation from the left or right lane of the vehicle to alert the driver to prevent a safety accident. Although the technology is proposed in Korean Patent Laid-Open Publication No. 2013-0009158, this is simply a warning to the driver, there is a disadvantage that it is difficult to induce the driver's intentional driving behavior to safe driving.

Therefore, a study on a safe driving guide system that induces a driver to voluntarily drive a safe driving behavior is required.

Hereinafter, with reference to the contents described in the accompanying drawings will be described embodiments of the present invention; However, the present invention is not limited or limited by the embodiments. Like reference numerals in the drawings denote like elements.

1 is a block diagram showing the configuration of a safe driving guide system 100 according to an embodiment of the present invention.

Referring to FIG. 1, the safety driving guide system 100 according to an embodiment of the present invention may include a vehicle information receiver 110, a camera information receiver 120, and a safety index scoring unit 130.

First, the vehicle information receiver 110 receives vehicle device information from an on board diagnostics (OBD) terminal provided on one side of the vehicle. The OBD terminal may transmit information, such as information on the main system of the vehicle or a failure transmitted to the ECU from the sensors attached to the vehicle, to the vehicle information receiving unit 110 to be viewed on the console or external device of the vehicle. The vehicle information receiver 110 serves to provide the received information to the safety index scoring unit 130.

In more detail, the vehicle information receiving unit 110 may receive the vehicle speed, starting and stopping, rapid braking, RPM, fuel economy and other vehicle information from the OBD terminal, and among the received information, The relevant information is provided to the safety index scoring unit 130. Here, the sudden start and sudden braking information may mean information determined as sudden start or sudden braking when the speed change is greater than or equal to a predetermined value in a unit time set by the user. In this case, depending on the degree of change in the speed per unit time may be provided by dividing the grade of rapid start or sudden braking into a plurality of grades.

For example, in the case where the unit time set by the user is 1 second and the speed fluctuation during the 1 second is more than 30 km / h, the speed fluctuation is more than 30 km / h but less than 40 km / h. If you fall under 1 class, you can go to 40km / h or more and less than 50km / h, and if you are over 50km / h, you can provide information by dividing the level. have. In this case, the safety index score may be differently assigned according to each step.

The camera government receiver 120 may receive image information around the vehicle from a camera provided in the vehicle. To this end, the camera government receiver 120 is based on the image receiving unit 121 for receiving images from a plurality of cameras provided on one side of the vehicle and the number of lane changes per unit time, distance information, blind spot vehicle based on the received image The image information analyzer 122 may serve to extract at least one of the information and provide the safety index scoring unit 130 to the safety index scoring unit 130.

Here, the image information analyzer 122 may recognize the lane through image recognition to determine whether the preset lane change per unit time is more than a preset number of times, and when the lane change per unit time is more than the preset number of times, dangerous driving This can be reflected when calculating the safety index score. For example, if the preset unit time is 5 seconds and the number of lane changes is 3 or more within the 5 seconds, the driver determines that the driver has made a dangerous driving and reflects this when calculating the safety index score (ex. As a deduction index). Can be. Also in this case, it can be determined by varying the grade according to the number of lane changes, for example, if the number of lane changes is more than 3 times and less than 5 times, it is a grade 1 sudden change, and if more than 5 times and less than 7 times Level 2 rapid change, and in seven or more cases, can be classified as level 3 sudden change.

In addition, the average of the distance between the driving time is calculated, and if the calculated distance is less than the predetermined distance it can be determined that the safe driving has not been applied as a deduction factor when calculating the safety index score.

In addition, the blind spot vehicle information may be used as an example as follows. If a vehicle is detected in the blind spot while driving, the driver is warned that the vehicle is present in the blind spot. If the driver forcibly changes lanes after receiving the warning, it is determined that the driver is not driving safely. It can be a deduction factor. As an example of a deduction application method, a deduction application may be applied immediately after a lane change is made after a warning is received, and a deduction application is applied when the number of times the lane change is received after the warning is counted more than the predetermined number of times. It can also be operated.

The safety index scoring unit 130 may derive a safety index by setting points for individual driving actions of the user based on the received vehicle device information and the image information. In this case, the safety index scoring unit 130, for example, calculates a deduction point for the dangerous driving behavior of the driver through the information provided, and determines the premium level according to the driver to calculate the premium differently for each grade Can lead to safe driving.

For example, an insurance company may calculate an insurance index for calculating a premium, and in order to calculate the insurance index, the safety index scoring unit 130 is calculated from a base score calculated based on a driver's career and a premium payment period. The final safety index can be determined by subtracting the calculated safety index. For example, if the driver's safety index of the two drivers (ex. A, B) whose base index is the same (e.g. 100 points) due to the same driver's experience, premium payment period, etc. is the same (ex. The index is 80 points, and the insurance index is 60 points, so that it can be decided to pay more premiums than A is.

Hereinafter, the safety index scoring unit 130 will be described in more detail with reference to FIGS. 2 and 3.

2 is a view showing a safety index calculation method of the safe driving guide system 100 according to an embodiment of the present invention, divided into three states, such as traffic facilitation, traffic general, and traffic congestion according to traffic conditions to the driver's dangerous driving behavior The deduction score can be scored differently.

In addition, Figure 3 is a view showing the insurance premium calculation criteria for each safety index of the safe driving guide system 100 according to an embodiment of the present invention, A, B, C, D according to the deduction interval based on the scored deduction points In other words, the insurance premiums of the driver are calculated by dividing the five premium grades of E, and setting the discount / period to be different for each grade.

Referring to the example shown in FIGS. 2 and 3, for example, the driver has exceeded 5% of the vehicle speed in the 'traffic-general' situation, 5 times of 'start-up' and 5 times of 'brake' per hour. If the distance between cars is less than 10% of the safety distance and the lane change per unit time is performed eight times per hour, one point is deducted from the speed of the vehicle, two points are deducted from the rapid start, and two are from the sudden braking. The deductible grade, 1 point deduction in the 'car distance', and 2 points deduction in the 'lane change per unit time' totaling 8 points, resulting in a premium grade of 'C', resulting in a 10% premium increase.

4 is an operation flowchart of the safe driving guide system 100 according to an embodiment of the present invention.

Referring to FIG. 4, in step 10, the driver may start driving.

In operation 20, at least one of the speed, starting and stopping information of the vehicle may be extracted and provided to the next step from the OBD terminal provided in the vehicle for the driver's driving behavior.

In step 21, images are received from a plurality of cameras provided on one side of the vehicle for the driver's driving behavior, and at least one of lane change counts, distance information, and blind spot vehicle information per unit time is extracted and provided to the next step. Can be.

In step 30, the safety index can be derived and provided to the next step.

In step 40, the premium rating may be calculated using the provided safety index.

In step 50, the premium may be calculated by reflecting the calculated premium grade.
