[Technical field]

[0001] The present invention relates to a device for determining whether a vehicle is being driven recklessly, the vehicle repeatedly performing sudden acceleration, sudden deceleration, or sharp turns. [Background technology]

[0002] Patent Document 1 describes a dangerous driving prevention device that is configured to determine whether or not the vehicle is driving recklessly based on detection values ​​from operating parts such as the steering wheel, accelerator pedal, and brake pedal installed in the vehicle, the vehicle speed, the distance to the vehicle ahead, etc., and if it is determined that the vehicle is driving recklessly, to limit the amount of accelerator operation depending on the number of times the vehicle has driven recklessly.

[0003] [Patent Document 1] JP 2019-121243 A Summary of the Invention [Problem to be solved by the invention]

[0004] The dangerous driving prevention device described in Patent Document 1 judges whether or not dangerous driving is being performed based on the driving operation of the vehicle itself. On the other hand, when a vehicle ahead or a following vehicle is driving dangerously, the vehicle may suddenly perform an accelerator operation, a brake operation, or a steering operation to avoid the danger, or the distance between the vehicle and the vehicle ahead may suddenly decrease. Even if a driving operation is performed to avoid such a danger, the dangerous driving prevention device described in Patent Document 1 may judge the driving operation to be dangerous based on the driving operation of the vehicle itself, and if acceleration restriction or the like is performed when the driving is judged to be dangerous, the degree of freedom of driving of the vehicle that is not driving dangerously will be restricted, and the driver may feel uncomfortable.

[0005] The present invention has been made in light of the above technical problems, and aims to provide a reckless driving vehicle determination device that can appropriately determine vehicles that are engaged in reckless driving. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention provides a reckless driving vehicle determination device that receives data on driving behavior of a predetermined vehicle and other vehicles traveling within a predetermined range of the predetermined vehicle and determines which vehicles are engaged in reckless driving. It is a place a dangerous driving level determination unit that determines a level of dangerous driving of the specified vehicle based on the data of the driving behavior of the specified vehicle; and when the level of dangerous driving of the specified vehicle determined by the dangerous driving level determination unit is equal to or higher than a predetermined level, a reporting unit that reports data identifying the specified vehicle and data that can determine the driving behavior of the specified vehicle to the police; and when the level of dangerous driving of the specified vehicle determined by the dangerous driving level determination unit is equal to or higher than the specified level, a data comparison unit that compares data on the driving behavior of the specified vehicle with data on the driving behavior of the other vehicle; a cause vehicle identification unit that determines whether or not the driving behavior of the specified vehicle is caused by the driving behavior of the other vehicle based on the data on the driving behavior of the specified vehicle and the data on the driving behavior of the other vehicle compared by the data comparison unit; and a reckless driving vehicle determination unit that determines that the specified vehicle is engaging in reckless driving when the cause vehicle identification unit determines that the driving behavior of the specified vehicle is not caused by the driving behavior of the other vehicle. and an output limiting unit that, when it is determined that the predetermined vehicle is engaged in dangerous driving, limits the output of the predetermined vehicle with the permission of the police. The present invention is characterized in that it is provided with: Effect of the Invention

[0007] According to this invention, data on the driving behavior of a predetermined vehicle is received, and the level of dangerous driving of the predetermined vehicle is determined based on the data on the driving behavior. When the level of dangerous driving of the predetermined vehicle is equal to or higher than a predetermined level, the data on the driving behavior of the predetermined vehicle and the other vehicle are compared to determine whether the driving behavior of the predetermined vehicle is caused by the driving behavior of the other vehicle or not based on the comparison result. Then, when it is determined that the driving behavior of the predetermined vehicle is not caused by the driving behavior of the other vehicle, it is determined that the predetermined vehicle is performing dangerous driving. In other words, when the driving behavior of the predetermined vehicle is caused by the driving behavior of the other vehicle, it is determined that the predetermined vehicle is not performing dangerous driving. That is, when the predetermined vehicle is performing driving equivalent to dangerous driving in order to avoid danger due to dangerous driving of a front vehicle or a following vehicle, it can be excluded from the determination that the predetermined vehicle is performing dangerous driving. Therefore, it is possible to appropriately determine a vehicle performing dangerous driving due to the driver's intention. [Brief description of the drawings]

[0008] [Figure 1] 1 is a schematic diagram for explaining an example of a dangerous-driving vehicle determination device according to an embodiment of the present invention; [Diagram 2] 4 is a flowchart for explaining an example of control executed by a reckless driving vehicle determination device in an embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The present invention will be described below based on the embodiment shown in the drawings. Note that the embodiment described below is merely one example of a specific embodiment of the present invention, and is not intended to limit the present invention.

[0010] Fig. 1 is a schematic diagram for explaining an example of a dangerous driving vehicle determination device according to an embodiment of the present invention. The dangerous driving vehicle determination device 1 shown in Fig. 1 is provided in a server 3 capable of receiving data from a plurality of vehicles 2. The server 3 shown in Fig. 1 is provided so as to be able to communicate with a plurality of base stations 4 capable of receiving data on driving behavior from the vehicles 2 traveling within a predetermined range, and is configured to obtain data on the driving behavior of the vehicles 2 via the base stations 4.

[0011] The driving behavior data is data required to determine whether or not dangerous driving is being performed, and includes, for example, acceleration, deceleration, steering angle and angular velocity, the traveling position of the vehicle 2, and the distance between the preceding and following vehicles. In addition to the driving behavior data, the system is configured to receive image data from a drive recorder or the like from a vehicle 2 that may be driving dangerously. That is, the amount of data transmitted from the vehicle 2 to the server 3 is limited, and when it is determined that the vehicle 2 may be driving dangerously, the system is configured to release the limit on the amount of data transmitted from the vehicle 2 to the server 3, so that the server 3 can receive information of a relatively large amount of data, such as image data.

[0012] The dangerous driving vehicle determination device 1 provided in the above-mentioned server 3 includes a dangerous driving level determination unit 5 that determines the level of dangerous driving of the vehicle 2, a reporting unit 7 that reports to the police 6, a data comparison unit 8 that compares data on the driving behavior of at least two vehicles 2, a causing vehicle identification unit 9 that determines whether the driving behavior of the vehicle 2 is equivalent to dangerous driving due to the driving behavior of another vehicle 2, a dangerous driving vehicle determination unit 10 that determines that the vehicle 2 is engaging in dangerous driving, and an output limiting unit 11 that outputs a signal to limit the driving force of the vehicle 2.

[0013] The dangerous driving level determination unit 5 is configured to determine the dangerous driving level of each vehicle 2 based on the driving behavior data input to the server 3. For example, a plurality of dangerous driving levels according to the magnitude of acceleration and deceleration are predefined, and the dangerous driving level of the vehicle 2 is determined by comparing the data input to the server 3 with the predefined dangerous driving levels. Similarly, the dangerous driving level may be determined based on the steering angle and its angular velocity. Furthermore, since dangerous driving can be assumed to be performed by combining acceleration / deceleration operations and steering operations, a map for determining the dangerous driving level using the acceleration / deceleration and steering angle as parameters may be constructed, and the dangerous driving level may be determined by referring to the map. Alternatively, the dangerous driving level may be determined based on a model predefined by machine learning. Specifically, a test run according to each stage of the dangerous driving level may be performed, and a model for determining the dangerous driving level may be predefined by supervised learning using the driving behavior data such as the acceleration / deceleration and steering angle acquired at that time as input data, and the dangerous driving level may be determined based on the driving behavior data input to the server 3 and the constructed model.

[0014] The reporting unit 7 is configured to report information about the vehicle 2 (hereinafter, referred to as specific vehicle B) whose driving behavior is determined by the dangerous driving level determination unit 5 to be equivalent to dangerous driving to the police 6. Specifically, the reporting unit 7 transmits to the police 6 data that can identify the specific vehicle B, such as the driving position of the specific vehicle B, and data that can determine the driving behavior of the specific vehicle B, such as driving behavior data. Furthermore, if the specific vehicle B is equipped with a drive recorder, the image data thereof is transmitted in addition to the driving behavior data and the like.

[0015] The data comparison unit 8 compares the driving behavior data of the specific vehicle B with the driving behavior data of a vehicle 2 (hereinafter, referred to as another vehicle A) around the specific vehicle B. Compared toSpecifically, the data on the driving behavior of the specific vehicle B is compared with the data on the driving behavior of another vehicle A within a receivable area (predetermined range) by the base station 4 that receives data from the specific vehicle B. This is because there is a possibility that the driving behavior of the specific vehicle B is determined to be a driving behavior equivalent to dangerous driving due to a driving operation to avoid a collision with the other vehicle A or an obstacle.

[0016] The causing vehicle identification unit 9 is configured to determine whether or not the driving behavior of the specific vehicle B is a driving behavior equivalent to dangerous driving due to a driving operation for avoiding a collision with the other vehicle A or an obstacle, from the driving behavior data compared by the data comparison unit 8. That is, the causing vehicle identification unit 9 is configured to determine whether or not the driving behavior of the specific vehicle B is a driving behavior equivalent to dangerous driving due to the driving behavior of the other vehicle A. Specifically, the causing vehicle identification unit 9 determines whether or not the driving behavior of the specific vehicle B is a driving behavior equivalent to dangerous driving due to the driving behavior of the other vehicle A, based on the time series of the driving behavior of the other vehicle A and the driving behavior of the specific vehicle B, such as whether or not the specific vehicle B accelerates or decelerates after the other vehicle A abruptly accelerates or decelerates, and whether or not the specific vehicle B operates the steering wheel after the other vehicle A abruptly operates the steering wheel.

[0017] In addition, it may be determined whether the driving behavior of the specific vehicle B corresponds to dangerous driving due to a driving operation for avoiding a collision with another vehicle A or an obstacle based on a model previously constructed by machine learning. Specifically, driving behavior data as test data of a vehicle that drives recklessly and driving behavior data as test data of a vehicle that follows the recklessly driven vehicle, runs in front of the recklessly driven vehicle, or runs alongside the recklessly driven vehicle are previously acquired, and a model for determining whether the driving operation for avoiding a collision with the recklessly driven vehicle corresponds to dangerous driving is previously constructed by supervised learning using the acquired data as input data, and it may be determined whether the driving operation of the specific vehicle B corresponds to dangerous driving due to a driving operation for avoiding a collision with the recklessly driven vehicle corresponds to dangerous driving based on the driving behavior data of the specific vehicle B and the other vehicle A input to the server 3 and the above-mentioned constructed model.

[0018] The reckless driving vehicle determination unit 10 is configured to determine the specific vehicle B as a vehicle engaged in reckless driving when the causing vehicle identification unit 9 determines that the driving behavior of the specific vehicle B is not due to driving operations intended to avoid a collision with another vehicle A or an obstacle.

[0019] The output limiting unit 11 is configured to limit the output of the specific vehicle B when the specific vehicle B is determined to be a vehicle being driven recklessly by the reckless driving vehicle determination unit 10. Specifically, when the driving position of the specific vehicle B is a position where it can be stopped, the output limiting unit 11 is configured to stop the specific vehicle B, and when it is not a position where it can be stopped, the output limiting unit 11 is configured to limit the output of the driving force source by, for example, setting an upper limit vehicle speed.

[0020] Fig. 2 shows a flowchart for explaining an example of control executed by the dangerous driving vehicle determination device 1. In the control example shown in Fig. 2, first, a dangerous driving level is determined from data on the driving behavior of a predetermined vehicle 2 (step S1). This step S1 can be determined by the dangerous driving level determination unit 5. Note that the predetermined vehicle 2 for which the dangerous driving level is determined does not include vehicles that are running on private land such as a circuit based on position information or the like.

[0021] Next, it is determined whether the dangerous driving level determined in step S1 is equal to or higher than a predetermined level (step S2). This step S2 is a step for determining whether the driving behavior is at a level that is dangerous to surrounding vehicles, and therefore the predetermined level in step S2 may be a level determined by test driving or the like.

[0022] If the dangerous driving level determined in step S1 is below the predetermined level and therefore the result in step S2 is negative, this routine is terminated. In other words, it is determined that the vehicle 2 whose dangerous driving level has been determined in step S1 is not being driven dangerously.

[0023] On the other hand, if the dangerous driving level determined in step S1 is equal to or higher than the predetermined level and thus the affirmative determination is made in step S2, the police 6 is notified (step S3). This step S3 is executed by the notification unit 7. That is, the driving behavior of the vehicle 2 whose dangerous driving level has been determined in step S1 is determined to be a specific vehicle B whose driving behavior corresponds to dangerous driving, and data for identifying the specific vehicle B and data for determining the driving behavior of the specific vehicle B are transmitted to the police 6. Furthermore, the restriction on the communication amount of data transmitted from the specific vehicle B to the server 3 is lifted, and image data of the drive recorder mounted in the specific vehicle B is transmitted to the police 6.

[0024] Next, it is determined whether or not there is a vehicle 2 around the specific vehicle B whose dangerous driving level is equal to or higher than a predetermined level (step S4). In this step S4, for example, the dangerous driving level of the other vehicle is determined in the same manner as in step S1 above, based on the driving behavior data of the other vehicle acquired by the base station 4 that communicates with the specific vehicle B, and it is also determined whether or not the dangerous driving level is equal to or higher than a predetermined level.

[0025] If the result of step S4 is negative because there is no vehicle 2 with a dangerous driving level equal to or higher than a predetermined level among the vehicles 2 around the specific vehicle B, it is considered that the specific vehicle B is driving dangerously alone or the driver of the specific vehicle B is intentionally driving dangerously. Therefore, the specific vehicle B is identified or determined as a dangerous driving vehicle, and the output of the specific vehicle B is restricted after obtaining permission from the police 6. Specifically, it is determined whether the specific vehicle B is traveling in a section where it can be stopped (step S5). This step S5, for example, identifies the traveling position of the specific vehicle B based on map information that can be obtained by a GPS or a navigation system, and determines whether the section is a stoppable section based on the laws and regulations set for the traveling position. Alternatively, it may be determined whether there is traffic congestion using artificial intelligence or the like using the position information of the vehicle 2 acquired by the base station 4 and the position information of the specific vehicle B, and whether it is possible to stop.

[0026] If the specific vehicle B is traveling in a section where it can stop and thus the answer is affirmative in step S5, the output of the specific vehicle B is restricted to stop the specific vehicle B (step S6), and this routine is temporarily terminated. Conversely, if the specific vehicle B is not traveling in a section where it can stop and thus the answer is negative in step S5, the output of the specific vehicle B is restricted so that the vehicle speed of the specific vehicle B can be restricted (step S7), and this routine is temporarily terminated.

[0027] On the other hand, if the answer to step S4 is affirmative because the vehicle 2 surrounding the specific vehicle B has a dangerous driving level equal to or higher than a predetermined level, it is determined whether the driving behavior of the specific vehicle B is a driving behavior equivalent to dangerous driving due to the driving behavior of the surrounding vehicle 2. Specifically, first, the causing vehicle of dangerous driving is identified from among the specific vehicle B and a vehicle (hereinafter referred to as other vehicle A) whose dangerous driving level determined in step S4 is equal to or higher than a predetermined level (step S8). The causing vehicle in step S8 can be identified by the data comparison unit 8 and the causing vehicle identification unit 9. That is, the data of the driving behavior of the specific vehicle B and the other vehicle A are compared by the data comparison unit 8, and if the causing vehicle identification unit 9 determines based on the compared data that the driving behavior of the specific vehicle B is not due to a driving operation for avoiding a collision with the other vehicle A or an obstacle, the specific vehicle B is identified as the causing vehicle, and if the causing vehicle identification unit 9 determines that the driving behavior of the specific vehicle B is due to a driving operation for avoiding a collision with the other vehicle A or an obstacle, the other vehicle A is identified as the causing vehicle.

[0028] Next, it is determined whether the causing vehicle identified in step S8 is specific vehicle B or not (step S9), and if the cause vehicle is specific vehicle B and the determination in step S9 is affirmative, the process proceeds to step S5. That is, it is determined that specific vehicle B is a vehicle engaged in reckless driving, and the output of specific vehicle B is restricted. On the other hand, if the cause vehicle identified in step S8 is not specific vehicle B and the determination in step S9 is negative, the routine is immediately terminated. That is, it is determined that reckless driving is not being engaged in.

[0029] As described above, the data of the driving behavior of the specific vehicle B is received, and the level of dangerous driving of the specific vehicle B is determined based on the data of the driving behavior. When the level of dangerous driving of the specific vehicle B is equal to or higher than a predetermined level, the data of the driving behavior of the specific vehicle B and the other vehicle A are compared to determine whether the driving behavior of the specific vehicle B is caused by the driving behavior of the other vehicle A or not based on the comparison result. Then, when it is determined that the driving behavior of the specific vehicle B is not caused by the driving behavior of the other vehicle A, it is determined that the specific vehicle B is performing dangerous driving. In other words, when the driving behavior of the specific vehicle B is caused by the driving behavior of the other vehicle A, it is determined that the specific vehicle B is not performing dangerous driving. That is, when the specific vehicle B is performing driving equivalent to dangerous driving in order to avoid danger due to dangerous driving of a front vehicle or a following vehicle, it is possible to exclude the specific vehicle B from the determination that it is performing dangerous driving. Therefore, it is possible to appropriately determine a vehicle performing dangerous driving due to the driver's intention. [Explanation of symbols]
