However, although these dangerous driving behavior detection technologies can effectively detect the dangerous driving behavior of the driver, they cannot judge the danger degree of the dangerous driving behavior of the driver, so the driver cannot know the risk corresponding to the dangerous driving behavior. Degree, so it is impossible to effectively modify your driving behavior. Therefore, these dangerous driving behavior detection technologies cannot achieve high efficiency.

There are also some dangerous driving behavior detection technologies that use data analysis or biometric analysis to determine whether the driver has produced dangerous driving behavior. However, these dangerous driving behavior detection technologies still cannot effectively determine the degree of danger of the driver's dangerous driving behavior. Therefore, these dangerous driving behavior detection technologies cannot achieve high efficiency.

In addition, since the use of pricing insurance (Ubiage-Base Insurance, UBI) has become a future trend, if you want to apply the pricing insurance to car insurance, you must provide a dangerous degree that can effectively determine the driver's dangerous driving behavior.

In the following, embodiments of the system and method for detecting the degree of dangerous driving behavior according to the present invention will be described with reference to related drawings. For the sake of clarity and convenience of illustration, the components in the drawings may be in size and proportion. Will be exaggerated or reduced. In the following description and / or patent application, when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements may be present; and when an element is referred to When "directly connected" or "directly coupled" to another element, there are no intervening elements present, and other words used to describe the relationship between elements or layers should be interpreted the same way. In order to facilitate understanding, the same elements in the following embodiments are described with the same symbols.

Please refer to FIG. 1, which is a block diagram of a first embodiment of a system capable of detecting the degree of dangerous driving behavior according to the present invention. As shown in the figure, the system 1 capable of detecting the degree of dangerous driving behavior may include a detection module 11, a processing module 12, and a warning module 13.

The detection module 11 can measure the moving speed of the vehicle C and can be transmitted to the processing module 12; in a preferred embodiment, the detection module 11 can be a speed sensor or any other kind of vehicle condition collection Device.

The processing module 12 can monitor the moving speed of the vehicle C, and can effectively calculate and quantify the danger degree of the dangerous driving behavior of the driver of the vehicle C according to the cumulative algorithm based on the moving speed of the vehicle C; in a better implementation For example, the aforementioned dangerous driving behavior may be a sudden acceleration behavior or a sudden deceleration (rapid braking) behavior.

The processing module 12 can monitor the speed change of each time interval on the time axis of the moving speed of the vehicle C. Among them, each time interval can include a plurality of time units, and any one time interval and the next time interval can partially overlap . If the processing module 12 detects that the speed change in one direction at any time interval exceeds a threshold value, the processing module 12 can judge that a dangerous driving behavior has occurred; wherein, the above direction may be an increasing direction or a decreasing direction.

In addition, if the processing module 12 finds a dangerous driving behavior in a time interval, and the moving speed of the vehicle C continues to change in that direction in the next time interval, the processing module 12 can judge that the danger degree of the dangerous driving behavior increases. Similarly, if the processing module 12 monitors that the moving speed of the vehicle C continues to change in that direction in subsequent time intervals, the processing module 12 can increase the danger level of the dangerous driving behavior.

In more detail, when the processing module 12 detects that the moving speed of the vehicle C continues to change in that direction at any two adjacent time intervals, the processing module 12 can judge that the danger degree of the dangerous driving behavior increases by the first level, and When the processing module 12 detects that the moving speed of the vehicle C continuously changes in that direction at any two adjacent time intervals and the speed change exceeds a threshold value, the processing module 12 can judge that the danger degree of the dangerous driving behavior increases by a second level. Therefore, the processing module 12 can accumulate the danger degree of the dangerous driving behavior when it is monitored that the moving speed of the vehicle C continuously changes to the direction in a plurality of consecutive time intervals. When the processing module 12 detects that the moving speed of the vehicle C does not continue to change in that direction at any two adjacent time intervals, the processing module 12 may determine that the dangerous driving behavior is over.

In the above manner, the processing module 12 can continuously accumulate the danger degree of the dangerous driving behavior and accurately reflect and quantify the danger degree of the dangerous driving behavior according to the magnitude of the speed change. In a preferred embodiment, the aforementioned carrier C may be a car or other various vehicles; and the processing module may be a portable electronic device, a wearable electronic device, a fixed electronic device, or a cloud computing platform. One or a combination of two or more of them.

The warning module 13 can send a warning signal according to the calculation result of the processing module 12. Among them, the warning module 13 can issue a warning signal according to the dangerous driving behavior, and can change the warning mode of the warning signal according to the dangerous degree of the dangerous driving behavior. In a preferred embodiment, the warning signal can be a sound warning signal, a vibration warning signal , One or two or more of the light warning signal or the image warning signal. For example, the warning module 13 can change the volume or frequency of the sound warning signal to reflect the danger degree of the dangerous driving behavior.

From the above, it can be known that the system 1 capable of detecting the degree of dangerous driving behavior in this embodiment can accurately calculate and quantify the danger degree of the dangerous driving behavior of the driver, so the processing module 12 can calculate insurance based on the degree of dangerous driving behavior. Cost, so it is very suitable for integration with the use of pricing insurance (Ubiage-Base Insurance, UBI) to apply to automobile insurance.

In addition, the system 1 capable of detecting the degree of dangerous driving behavior in this embodiment can not only detect the dangerous driving behavior of the driver in real time and issue a warning signal, but also can accurately determine the degree of danger of the dangerous driving behavior of the driver. The degree of danger of driving behavior changes the warning mode of the warning signal, so that the driver can know the degree of risk corresponding to his dangerous driving behavior to effectively modify his driving behavior. Therefore, the system 1 that can detect the degree of dangerous driving behavior can achieve more Good performance.

In addition, the system 1 capable of detecting the degree of dangerous driving behavior in this embodiment can use an accumulation algorithm, which can continuously accumulate the degree of danger of dangerous driving behavior and accurately reflect and quantify the degree of danger of dangerous driving behavior according to the magnitude of the speed change. The system 1 capable of detecting the degree of dangerous driving behavior in this embodiment can achieve extremely high accuracy.

Of course, the above is just an example. The structure and function of the system 1 capable of detecting the degree of dangerous driving behavior can be changed according to actual needs, and the present invention is not limited thereto.

Please refer to FIG. 2, which is a flowchart of the first embodiment of the present invention. As shown in the figure, the method for detecting the degree of dangerous driving behavior by the system 1 capable of detecting the degree of dangerous driving behavior may include the following steps: In step S21, the moving speed of the vehicle is measured.

In step S22, the speed change of each time interval of the monitoring vehicle's moving speed on the time axis is monitored, and when the speed change in one direction in any one time interval exceeds a threshold value, it is judged that a dangerous driving behavior occurs.

In step S23, a warning signal is issued based on the dangerous driving behavior.

In step S24, the moving speed of the vehicle is monitored, and when the moving speed of the vehicle continues to change in that direction at the next time interval, it is judged that the degree of danger of the dangerous driving behavior increases.

In step S25, the warning mode of the warning signal is changed according to the danger degree of the dangerous driving behavior.

In step S26, the insurance cost is calculated based on the degree of danger of the dangerous driving behavior.

In step S27, the moving speed of the vehicle is monitored, and when the moving speed of the vehicle does not continuously change in that direction at any two adjacent time intervals, it is determined that the dangerous driving behavior is over.

It is worth mentioning that the dangerous driving behavior detection technology of the know-how cannot determine the degree of danger of the dangerous driving behavior of the driver, so the driver cannot know the degree of risk corresponding to the dangerous driving behavior, and therefore cannot effectively modify it. Because of your own driving behavior, the efficiency can never be improved. On the contrary, according to the embodiment of the present invention, the system capable of detecting the degree of dangerous driving behavior can not only detect the dangerous driving behavior of the driver in real time and issue a warning signal, but also accurately determine the degree of danger of the dangerous driving behavior of the driver. The warning mode of the warning signal can be changed according to the degree of danger of the dangerous driving behavior; therefore, the driver can know the degree of risk corresponding to the dangerous driving behavior to effectively modify his driving behavior, so the system can achieve better performance.

In addition, the dangerous driving behavior detection technology of the conventional technique cannot determine the degree of danger of the dangerous driving behavior of the driver, and therefore cannot be applied to the use of pricing insurance. On the contrary, according to the embodiment of the present invention, the system capable of detecting the degree of dangerous driving behavior can accurately determine the degree of danger of the driver's dangerous driving behavior, and thus can be integrated with the use of pricing insurance for application to automobile insurance.

In addition, according to an embodiment of the present invention, a system capable of detecting the degree of dangerous driving behavior may adopt an accumulation algorithm, which may continuously accumulate the degree of danger of the dangerous driving behavior and accurately reflect and quantify the degree of danger of the dangerous driving behavior according to the magnitude of the speed change. Therefore, the system can achieve extremely high accuracy.

Please refer to FIG. 3 and FIG. 4, which are a first schematic diagram and a second schematic diagram of the second embodiment of the system capable of detecting the degree of dangerous driving behavior of the present invention. As shown in FIG. 3, the system 2 capable of detecting the degree of dangerous driving behavior may include a speed sensor 21 and a portable electronic device 22A. Among them, the speed sensor 21 may correspond to the detection mode of the first embodiment. The portable electronic device 22A can correspond to the processing module and the warning module of the first embodiment. The system 2 for detecting the degree of dangerous driving behavior can effectively detect the dangerous driving behavior and the degree of danger of the driver of the vehicle C. In this embodiment, the rapid acceleration behavior of the driver of the vehicle C is described as an example.

The speed sensor 21 can measure the moving speed of the carrier C, and can transmit it to the portable electronic device 22A.

The portable electronic device 22A can monitor the moving speed of the vehicle C, and detect the rapid acceleration behavior of the driver of the vehicle C according to the moving speed of the vehicle C, and can be effective according to the moving speed of the vehicle C according to the accumulation algorithm Calculate and quantify the danger of the driver's rapid acceleration behavior of vehicle C, and can also send corresponding warning signals to notify the driver of vehicle C. In this embodiment, the portable electronic device 22A can be a smart type Mobile phones, tablets or laptops, etc. Of course, the portable electronic device 22A can also be a wearable electronic device (such as a smart watch or smart bracelet, etc.) or a fixed electronic device (such as a driving recorder or car entertainment) Device, etc.).

As shown in FIG. 4, the portable electronic device 22A can monitor the speed change of each time interval T1 ~ T15 of the moving speed of the vehicle C on the time axis TA, and can compare the speed changes of adjacent time units; In this embodiment, each time interval T1 to T15 may include five time units, and one time unit may be one second. In this embodiment, any one time interval and the next time interval may partially overlap and differ at least from each other. One time unit; for example, the time interval T1 (1 to 5 seconds) differs from the next time interval T2 (2 to 6 seconds) by one second and overlaps by four seconds. And if the portable electronic device 22A detects that the speed change of the adjacent time unit changes in an increasing direction and exceeds a threshold value, the portable electronic device 22A can determine that a rapid acceleration behavior has occurred.

In the portable electronic device 22A, in the time interval T1 (1 to 5 seconds), it is found that the speed change from the fourth to the fifth seconds exceeds the threshold value of 10km / h.

Then, the portable electronic device 22A detected that the moving speed of the vehicle C was within the time interval T3 (3 to 7 seconds) and found that the moving speed of the sixth to seventh seconds continued to increase. The portable electronic device 22A It can be judged that the danger degree of the rapid acceleration behavior is increased, and the danger degree of the rapid acceleration behavior can be increased by one level, and the accumulated number of times is recorded three times.

Next, the portable electronic device 22A monitored the movement speed of the vehicle C and found that when the movement speed of the seventh to eighth seconds continued to increase in the time interval T4 (4 ~ 8 seconds), and exceeded the threshold value of 10km / h, the portable electronic device 22A can judge that the danger degree of the rapid acceleration behavior is greatly increased, and can increase the danger degree of the rapid acceleration behavior by two levels, and record the number of accumulative times five times.

That is, when the portable electronic device 22A detects that the moving speed of the vehicle C continues to increase in any two adjacent time units, the portable electronic device 22A can judge that the danger degree of the rapid acceleration behavior is increased by one level, and will accumulate The number of times is increased by one, and when the portable electronic device 22A detects that the moving speed of the vehicle C continues to increase in any two adjacent time units and exceeds the threshold value of 10 km / h, the portable electronic device 22A can determine the rapid acceleration behavior Increase the level of danger by two and increase the cumulative number by two. In the above manner, the portable electronic device 22A can continuously accumulate the danger degree of the rapid acceleration behavior, and can accurately reflect and quantify the danger degree of the rapid acceleration behavior according to the magnitude of the speed change.

Of course, the above threshold can be adjusted according to different scenarios and road conditions. For example, the threshold for rapid acceleration can also be set to 12km / h or 13km / h.

When the portable electronic device 22A can detect the movement speed of the vehicle C and find that the movement speed of the fifteenth to sixteenth seconds does not increase continuously in the time interval T12 (12-16 seconds), the portable electronic device 22A The device 22A can judge the end of the rapid acceleration behavior. The portable electronic device 22A can continuously monitor the moving speed of the vehicle C to determine whether the rapid acceleration behavior has occurred again, and can reflect and quantify the danger degree of the rapid acceleration behavior through the above-mentioned manner.

At the same time, the portable electronic device 22A issues a warning signal according to the occurrence of the rapid acceleration action, and can change the warning mode of the warning signal according to the danger degree of the rapid acceleration action.

As can be seen from the above, the system 2 capable of detecting the degree of dangerous driving behavior in this embodiment can not only accurately determine the driver's rapid acceleration behavior, but also accurately calculate and quantify the danger degree of the driver's rapid acceleration behavior. Accelerating the degree of danger of the calculation of insurance costs is very suitable for integration with the use of pricing insurance for automobile insurance. And the driver can know the degree of risk corresponding to his rapid acceleration behavior according to the warning mode of the warning signal to effectively modify his driving behavior, thereby reducing the premium. Therefore, the system 2 capable of detecting the degree of dangerous driving behavior in this embodiment can indeed achieve better performance.

In addition, the system 2 capable of detecting the degree of dangerous driving behavior in this embodiment can use an accumulation algorithm, which can continuously accumulate the degree of danger and accurately reflect and quantify the degree of danger of rapid acceleration behavior according to the magnitude of the speed change.

Similarly, the portable electronic device 22A can monitor the speed change of each time interval T1 ~ T9 of the moving speed of the vehicle C on the time axis TA, and can compare the speed change of each adjacent time unit. When the electronic device 22A detects that the speed change of the adjacent time unit decreases in a decreasing direction and exceeds a threshold value, the portable electronic device 22A can determine that a sudden deceleration behavior has occurred.

In the portable electronic device 22A, in the time interval T1 (1 to 5 seconds), it is found that the speed change from the fourth to the fifth seconds exceeds the threshold value of 10km / h. The portable electronic device 22A can determine that a sudden deceleration has occurred, and When the portable electronic device 22A found that the moving speed from the fifth second to the sixth second continued to decrease in the next time interval T2 (2 to 6 seconds) and exceeded the threshold value of 10 km / h, the portable electronic device 22A could Judging that the danger degree of the sudden deceleration behavior has increased significantly, and the danger degree of the sudden deceleration behavior can be increased by two levels, and the accumulated number of times is recorded three times.

Next, when the portable electronic device 22A monitors the movement speed of the vehicle C and finds that the movement speed of the seventh to eighth seconds continues to decrease in the time interval T4 (4 to 8 seconds), the portable electronic device 22A It can be judged that the danger degree of the sudden deceleration behavior is increased, and the danger degree of the sudden deceleration behavior can be increased by one level, and the accumulative count is recorded five times.

Therefore, in a similar manner, the portable electronic device 22A can also continuously accumulate the danger degree of the rapid deceleration behavior and accurately reflect and quantify the danger degree of the rapid deceleration behavior according to the magnitude of the speed change.

Of course, the above threshold can be adjusted according to different scenarios and road conditions. For example, the rapid deceleration threshold can also be set to 11km / h or 12km / h.

When the portable electronic device 22A can detect that the moving speed of the vehicle C does not continue to decrease during the time interval T6 (6 to 10 seconds) from the ninth second to the tenth second, the portable electronic device 22A It can be judged that the sudden deceleration behavior is over. The portable electronic device 22A can continuously monitor the moving speed of the vehicle C to determine whether the sudden deceleration behavior has occurred again, and can reflect and quantify the danger degree of the rapid deceleration behavior through the above-mentioned manner.

At the same time, the portable electronic device 22A can issue a warning signal when the rapid deceleration behavior occurs, and can change the warning mode of the warning signal according to the danger degree of the rapid deceleration behavior.
