Embodiment 1 FIG.
FIG. 1 is a block diagram illustrating a configuration of the driving determination device 1 according to the first embodiment. The in-vehicle device 2 is a device connected to the server device 3 via the communication network 4, and may be an in-vehicle device provided in the vehicle or a portable device brought into the vehicle by an occupant. . FIG. 1 shows the in-vehicle device 2 of the vehicle A and the in-vehicle device 2 of the vehicle B. However, if the vehicle A can be connected to the server device 3 via the communication network 4, the number of vehicles having the in-vehicle device 2 is as follows. There may be three or more.

When the vehicle-mounted device 2 determines that a driving operation for avoiding a collision with an object outside the vehicle, such as sudden braking, sudden acceleration, or sudden steering, has been performed in a vehicle having the vehicle-mounted device 2, a predetermined operation is performed from the vehicle. The vehicle that has caused the driving operation is identified from the vehicles that existed within the distance range. Here, the distance range is, for example, a range within a radius of 10 m from the vehicle. Hereinafter, the vehicle on which this driving operation was performed is referred to as “first vehicle”, and when the driving operation was performed on the first vehicle, the vehicle was within the distance range of the first vehicle. The vehicle is referred to as "second vehicle". In addition, the distance range is referred to as “periphery” for convenience. That is, "the second vehicle existing within the distance range of the first vehicle" is described as "the second vehicle existing around the first vehicle".

運転 Driving operations such as sudden braking, sudden acceleration or sudden steering are driving operations that rapidly change the operation of the vehicle in order to avoid collision between the vehicle and an object outside the vehicle. Objects outside the vehicle include other vehicles, pedestrians, or features existing around the vehicle. In the following description, the above-described driving operation is referred to as “avoidance operation”. The in-vehicle device 2 notifies the second vehicle via the server device 3 of information indicating that the avoidance operation has been performed on the first vehicle due to the identified second vehicle.

The server device 3 receives the position information of the vehicle, the time information, and the identification information for identifying the vehicle from the vehicle-mounted device 2 via the communication network 4 at regular intervals, and transmits the position information and the time information of the vehicle to the identification information of the vehicle. Is managed in association with. The server device 3 relays transmission and reception of information between the vehicle-mounted devices 2.

For example, when the avoidance operation is performed on the vehicle A due to the vehicle B, the vehicle A is the first vehicle and the vehicle B is the second vehicle. At this time, the vehicle-mounted device 2 of the vehicle A transmits to the server device 3 warning information to the driver of the vehicle B and identification information for identifying the vehicle B. When the server device 3 identifies the vehicle B based on the identification information, the server device 3 transmits warning information to the driver of the vehicle B to the vehicle-mounted device 2 included in the vehicle B.

When the avoidance operation is performed on the vehicle B due to the vehicle A, the vehicle B is the first vehicle, and the vehicle A is the second vehicle. The in-vehicle device 2 of the vehicle B transmits to the server device 3 warning information to the driver of the vehicle A and identification information for identifying the vehicle A. When the server device 3 identifies the vehicle A based on the identification information, the server device 3 transmits warning information to the driver of the vehicle A to the in-vehicle device 2 included in the vehicle A.

FIG. 2 is a block diagram showing a configuration of the vehicle-mounted device 2 and the server device 3 in the driving determination device 1.

The information acquisition unit 20 acquires the vehicle information, the occupant status information, the image information outside the vehicle, the position information of the vehicle, and the time information indicating the time at which the information was obtained. As shown in FIG. 3, the information acquisition unit 20 includes a vehicle information acquisition unit 20a, an occupant status acquisition unit 20b, an outside image acquisition unit 20c, a position information acquisition unit 20d, and a time information acquisition unit 20e.

The vehicle information acquisition unit 20a acquires vehicle information relating to the driving operation of the vehicle. For example, the vehicle information acquisition unit 20a is connected to a control ECU (Electronic Control Unit) 40 mounted on the vehicle, and the vehicle information is acquired from the control ECU 40. The vehicle information includes, for example, vehicle speed, steering angle, acceleration, accelerator opening, and brake operation amount. The time at which the vehicle information was obtained by the vehicle information obtaining unit 20a is obtained by the time information obtaining unit 20e.

The occupant status acquisition unit 20b acquires the occupant status information detected by the occupant status detection device 41. While activated, the occupant status detection device 41 always analyzes the image captured by the in-vehicle imaging device and outputs a result of detecting the occupant status. The occupant's situation includes, for example, an eye open state indicating the occupant's gaze direction or the occupant's degree of drowsiness. The in-vehicle photographing device is a device for photographing a driver of the vehicle, and may be an infrared camera or an optical camera. The in-vehicle photographing device is installed at a position where at least the driver's face in the vehicle can be photographed. When the occupant status is detected by the occupant status detection device 41, the occupant status acquisition unit 20b immediately obtains occupant status information indicating the occupant status. The time when the occupant status information is obtained by the occupant status obtaining unit 20b, that is, the time when the occupant status is detected by the occupant status detecting device 41 is obtained by the time information obtaining unit 20e.

The vehicle outside photographing device 42 is a device for photographing a situation outside the vehicle, and is, for example, an infrared camera or an optical camera. The image information outside the vehicle is image information in which a situation around the vehicle that is visually recognized when the driver is driving is captured, and is, for example, an image in front of the vehicle that the driver watches while driving. The time at which the outside image information was acquired by the outside image acquisition unit 20c is acquired by the time information acquisition unit 20e.

The position information acquisition unit 20d acquires the position information of the vehicle. For example, the position information acquisition unit 20d is connected to a global positioning system (GPS) receiver 43, and obtains position information of the vehicle by analyzing the GPS information received from the GPS satellites by the GPS receiver 43. The time at which the vehicle exists at the position indicated by the position information is obtained by the time information obtaining unit 20e.

The time information acquisition unit 20e acquires time information at which the vehicle information, the occupant status information, the outside image information, and the position information are obtained. For example, the time information acquisition unit 20e may acquire time information from a timer built in the vehicle-mounted device 2, or may acquire time information from GPS information received by the GPS receiver 43.

The management unit 21 inputs the occupant status information, the image information outside the vehicle, the position information of the vehicle, and the time information acquired by the information acquisition unit 20, and converts the input occupant status information, the image information outside the vehicle, and the position information of the vehicle into time information.

The management unit 21 reads a part or all of the information included in the operation record information from the storage unit 22 in response to the information read request, and outputs the read information to the request source.

Since the driving record information includes the occupant status information, the outside image information, and the vehicle position information obtained at the same time, the driver's gaze state at the same time is analyzed by analyzing the driving record information. The user can know the situation around the vehicle and the position of the vehicle. Further, the driving record information may be information including vehicle information acquired by the vehicle information acquiring unit 20a in addition to the occupant status information, the image information outside the vehicle, and the position information of the vehicle. By analyzing this driving record information, it is possible to know the driver's gaze state, the situation around the vehicle, and the position of the vehicle at the time when the avoidance operation is performed. In the following description, the time at which the avoidance operation is performed is referred to as “avoidance operation time”.

The storage unit 22 is a storage device in which writing and reading of information are managed by the management unit 21. FIG. 2 illustrates the in-vehicle device 2 including the information acquisition unit 20, the management unit 21, and the storage unit 22, but the in-vehicle device 2 does not include the information acquisition unit 20, the management unit 21, and the storage unit 22. 2 may be included in a drive recorder provided separately from the drive recorder.

The driving operation determination unit 23 determines whether or not an avoidance operation has been performed on the vehicle based on the vehicle information acquired at any time by the vehicle information acquisition unit 20a while the vehicle is traveling. The determination of the driving operation by the driving operation determination unit 23 is executed at any time while the vehicle is traveling. For example, when the time change rate of the brake operation amount specified based on the vehicle information is larger than a threshold, the driving operation determination unit 23 determines that the vehicle has suddenly braked. In addition, when the time change rate of the steering angle specified based on the vehicle information is greater than the threshold, the driving operation determination unit 23 determines that the vehicle has been steered sharply.

When the driving operation determination unit 23 determines that the avoidance operation has been performed on the first vehicle, the vehicle identification unit 24 determines the occupant status information of the first vehicle at the avoidance operation time and the first vehicle at the avoidance operation time. Based on the position information of the second vehicle existing around the first vehicle, the second vehicle that caused the avoidance operation to be performed on the first vehicle is specified. For example, the vehicle specifying unit 24 determines a line-of-sight range based on the line-of-sight direction of the driver of the first vehicle at the avoidance operation time, and obtains position information of the second vehicle existing around the first vehicle. Among them, the second vehicle whose position information is included in the line of sight is specified.

The storage unit 32 is a storage device in which writing and reading of information are managed by the management unit 31. The storage unit 32 stores vehicle position information and time information in association with the vehicle identification information.

Next, the operation will be described.
FIG. 4 is a flowchart illustrating a driving determination method according to the first embodiment.
The information acquisition unit 20 acquires vehicle information of the first vehicle, occupant status information of the first vehicle, image information outside the vehicle, position information of the first vehicle, and time information (step ST1). The information acquired by the information acquisition unit 20 is output to the management unit 21 and stored in the storage unit 22. The vehicle information is output from the information acquisition unit 20 to the driving operation determination unit 23. The driving operation determining unit 23 determines whether the avoidance operation has been performed on the first vehicle based on the vehicle information acquired by the information acquiring unit 20 (step ST2). If the avoidance operation is not performed (step ST2; NO), the process returns to step ST1.

When the driving operation determination unit 23 determines that the avoidance operation has been performed on the first vehicle (step ST2; YES), the vehicle identification unit 24 instructs the management unit 21 to perform the avoidance operation time of the first vehicle. Request occupant status information indicating the status of the driver of the corresponding first vehicle. The management unit 21 reads out the occupant status information corresponding to the request from the storage unit 22 and outputs the read occupant status information to the vehicle identification unit 24.

The vehicle identifying unit 24 is located around the first vehicle at the avoidance operation time identified by the occupant status information of the first vehicle input from the management unit 21 and the position information of the first vehicle. Based on the position information of the second vehicle, the second vehicle that caused the avoidance operation to be performed on the first vehicle is specified (step ST3). The position information of the second vehicle existing around the first vehicle is acquired by the transmitting / receiving unit 26 from the server device 3. For example, the information generation unit 25 acquires the avoidance operation time and the position information of the first vehicle at this time from the driving operation determination unit 23, and generates position request information including the information. The transmission / reception unit 26 transmits the position request information to the server device 3.

The server device 3 reads the position information of the second vehicle corresponding to the position request information from the position information of the vehicle stored in the storage unit 32 for each time information, and transmits the position information to the vehicle-mounted device 2. The position information received from the server device 3 by the transmission / reception unit 26 is output to the vehicle identification unit 24 via the management unit 21. The vehicle specifying unit 24 specifies the second vehicle based on the occupant status information and the position information of the second vehicle existing around the first vehicle.

(4) Information indicating that the second vehicle specified by the vehicle specifying unit 24 is the cause of the avoidance operation performed on the first vehicle is transmitted to the second vehicle (step ST4). For example, the information generating unit 25 associates the avoidance operation time with the identification information of the second vehicle specified by the vehicle specifying unit 24, and sets the outside of the first vehicle at which the second vehicle was photographed at this time. Alert information including image information is generated. The transmission / reception unit 26 transmits the warning information generated by the information generation unit 25 to the server device 3. The transmission / reception unit 30 included in the server device 3 transmits the warning information received from the in-vehicle device 2 to the in-vehicle device 2 included in the second vehicle.

Next, a detailed process of the driving determination method according to the first embodiment will be described.
FIG. 5A is a flowchart illustrating a process on the vehicle-mounted device 2 side in the driving determination method according to the first embodiment. FIG. 5B is a flowchart showing processing on the server device 3 side in the driving determination method according to Embodiment 1. FIG. 6A is a schematic diagram showing a vehicle A, a vehicle B, and a vehicle C traveling on the road 50. FIG. 6B is a schematic diagram illustrating a state in which the vehicle A has suddenly braked according to the driving behavior of the vehicle B.

6A, each of the vehicle A, the vehicle B, and the plurality of vehicles C traveling on the road 50 has the vehicle-mounted device 2. The position information and the time information of each of the vehicles A, B, and C are managed by the server device 3 in association with the identification information of each vehicle. When the vehicle A is normally traveling on the road 50, the driver 200 of the vehicle A is gazing at the front, so that the line-of-sight direction 201 of the driver 200 is in front of the vehicle A as shown in FIG. It is suitable for running vehicle C.

When the vehicle A normally travels on the road 50, the information acquisition unit 20 included in the in-vehicle device 2 performs vehicle information on the vehicle A, occupant status information on the vehicle A, image information outside the vehicle, position information on the vehicle A, and time information. Is obtained (step ST1a). The information acquired by the information acquisition unit 20 is output to the management unit 21 and stored in the storage unit 22. The vehicle information is output from the information acquisition unit 20 to the driving operation determination unit 23. The driving operation determination unit 23 included in the in-vehicle device 2 determines whether the avoidance operation has been performed on the vehicle A based on the vehicle information on the vehicle A (step ST2a). If the avoidance operation has not been performed (step ST2a; NO), the above determination is repeated.

FIG. 6B shows, for example, a situation in which the driver 200 suddenly brakes on the vehicle A because the vehicle B changes lanes to the front of the vehicle A without leaving the turn signal. At this time, the driver 200 gazes at the vehicle B which is about to collide with the vehicle A, so that the line-of-sight direction 201 is directed to the vehicle B. The driving operation determination unit 23 determines that the vehicle A has undergone a sudden braking (avoidance operation) based on the vehicle information of the vehicle A (step ST2a; YES).

When the driving operation determination unit 23 determines that the avoidance operation has been performed on the vehicle A, the vehicle identification unit 24 instructs the management unit 21 to output the occupant status information including the gaze direction 201 of the driver 200 at the avoidance operation time. Is obtained from the storage unit 22 (step ST3a).

The information generation unit 25 acquires the avoidance operation time at which the avoidance operation was performed in the vehicle A and the position information of the vehicle A at this time from the driving operation determination unit 23, and generates position request information including these information. I do. The transmission / reception unit 26 transmits the position request information generated by the information generation unit 25 to the server device 3 via the communication network 4.

The management unit 31 determines a certain range around the position of the vehicle A based on the position information of the vehicle A included in the position request information received by the transmission / reception unit 30. Then, the management unit 31 retrieves the position information of the vehicle B and the plurality of vehicles C existing within a certain range at the avoidance operation time from the position information of the vehicle stored in the storage unit 32 for each time information. It reads out and outputs the read out position information to the transmitting and receiving unit 30. The transmission / reception unit 30 transmits the position information of the vehicle B and the plurality of vehicles C input from the management unit 31 to the vehicle-mounted device 2 included in the vehicle A.

The transmission / reception unit 26 provided in the vehicle-mounted device 2 receives the position information of the vehicle B and the plurality of vehicles C from the server device 3 via the communication network 4. These pieces of position information are sent to the vehicle identification unit 24 via the management unit 21. The vehicle specifying unit 24 determines the vehicle A based on the line-of-sight direction 201 of the driver 200 at the avoidance operation time and the position information of the vehicle B and the plurality of vehicles C existing around the vehicle A at the avoidance operation time. The vehicle that has caused the avoidance operation is identified (step ST4a).

For example, the vehicle identifying unit 24 determines the line-of-sight range 202 based on the line-of-sight direction 201 of the driver 200 at the avoidance operation time. The line-of-sight range 202 is a range to which the line of sight of the driver 200 may be directed, and has, for example, a certain central angle centered on a line along the line-of-sight direction 201 as shown in FIGS. 6A and 6B. This is a fan-shaped area.

The vehicle identification unit 24 determines the position information of the vehicle included in the line-of-sight range 202 among the position information of the vehicle B and the plurality of vehicles C existing around the vehicle A at the avoidance operation time. Further, the vehicle specifying unit 24 specifies the vehicle closest to the vehicle A among the vehicles whose position information is included in the line-of-sight range 202 as the vehicle that has caused the avoidance operation in the vehicle A. As a result, the vehicle B that caused the sudden braking of the vehicle A is specified.

The information generation unit 25 generates warning information to the driver of the vehicle B when the vehicle specifying unit 24 specifies the vehicle B that caused the avoidance operation in the vehicle A (step ST5a). For example, the information generation unit 25 generates warning information including the time at which the vehicle A is suddenly braked and the outside image information of the vehicle A at which the vehicle B is photographed at this time. The transmission / reception unit 26 transmits the warning information associated with the identification information of the vehicle B to the server device 3 (Step ST6a).

The transmission / reception unit 30 provided in the server device 3 receives the warning information and the identification information from the vehicle-mounted device 2 (Step ST1b). For example, the transmission / reception unit 30 identifies the vehicle B based on the identification information, and transmits warning information from the vehicle A to the in-vehicle device 2 included in the vehicle B (step ST2b).

車載 The in-vehicle device 2 of the vehicle B presents warning information to the driver of the vehicle B. For example, the in-vehicle device 2 displays, on the display screen, image information of the vehicle B (image information outside the vehicle) captured from the vehicle A at the time when the vehicle A suddenly brakes. By visually recognizing this image, the driver of the vehicle B can recognize that the sudden braking has been performed on the vehicle A due to the lane change performed on the vehicle B.

As described above, in the driving determination device 1 according to Embodiment 1, based on the occupant status information including the line-of-sight direction 201 of the driver 200 of the vehicle A and the position information of the vehicle existing around the vehicle A, Thus, the vehicle that caused the avoidance operation in the vehicle A is specified. Thereby, it is possible to notify the vehicle B that the driving operation has been performed on the vehicle A due to the vehicle B without being affected by the trajectory of the driving of the vehicle B.

Next, a modified example of the vehicle-mounted device 2 will be described.

The in-vehicle device 2A is a device connected to the server device 3 via the communication network 4 shown in FIG. 1, and may be an in-vehicle device provided in the vehicle or a portable device brought into the vehicle by an occupant. It may be a device.

The vehicle-mounted device 2A includes an information acquisition unit 20, a management unit 21, a storage unit 22, a driving operation determination unit 23, a vehicle identification unit 24, an information generation unit 25, a transmission / reception unit 26, and a driving state determination unit 27. The driving state determination unit 27 determines whether the cause of the avoidance operation performed on the first vehicle is the driving state of the occupant of the first vehicle. That is, the driving state determination unit 27 determines whether or not the driver of the first vehicle is performing careless driving when the avoidance operation is performed on the first vehicle. Inattentive driving includes inattentive driving, driving away, and drowsy driving.

(4) The driving state determination unit 27 requests the management unit 21 for operation record information up to a point in time that has been traced back by a certain time (for example, 30 seconds) from the avoidance operation time. The management unit 21 reads the operation record information requested by the operation state determination unit 27 from the storage unit 22 and outputs the read operation record information to the operation state determination unit 27. The driving state determination unit 27 determines whether or not the driver of the first vehicle has performed careless driving at the avoidance operation time based on the driving record information input from the management unit 21.

For example, based on the occupant status information included in the driving record information, the driving state determination unit 27 analyzes the driver's eye-opening state from the avoidance operation time to a point in time that is traced back by a certain time, and reaches the avoidance operation time. If the driver's eye opening degree is equal to or less than the threshold value by then, it is determined that the driver has been driving asleep. Further, based on the driver's line of sight from the avoidance operation time to a certain time before the avoidance operation time, the driving state determination unit 27 determines if the driver does not look ahead of the vehicle before the avoidance operation time. It may be determined that the driver is driving aside.

Next, the operation will be described.
FIG. 9 is a flowchart illustrating a process on the in-vehicle device 2A in the driving determination method according to the second embodiment. Processing other than step ST2a-1 in FIG. 9 is the same as step ST1a to step ST6a in FIG. 5A, and thus description thereof is omitted.

When the driving operation determination unit 23 determines that the avoidance operation has been performed on the first vehicle by the driving operation determination unit 23, the driving state determination unit 27 determines whether the driver has performed careless driving before the avoidance operation is performed. A determination is made (step ST2a-1). At this time, when it is determined by the driving state determination unit 27 that the driver is performing careless driving (step ST2a-1; YES), the in-vehicle device 2A does not execute the processing of step ST3a and subsequent steps, and executes the processing of step ST1a. Return to processing. Thus, when the avoidance operation is performed by the driver of the first vehicle with carelessness, the warning information is not transmitted to the second vehicle.

(4) When it is determined that the driver of the first vehicle has not performed careless driving (step ST2a-1; NO), the in-vehicle device 2A executes the processing after step ST3a. Thereby, if there is no care of the driver of the first vehicle, the warning information is transmitted to the second vehicle to which the driver pays attention when the avoidance operation is performed.

As described above, the driving determination apparatus 1A according to the second embodiment determines that the cause of the avoidance operation performed on the first vehicle depends on the driving state of the occupant of the first vehicle determined by the driving state determination unit 27. In some cases, the information indicating that the second vehicle is the cause of the avoidance operation performed on the first vehicle is not transmitted to the second vehicle. Thus, for example, when the avoidance operation is performed with carelessness of the driver of the first vehicle, the warning information is not transmitted. Therefore, transmission of inappropriate warning information can be prevented.

Embodiment 3 FIG.
The driving determination device according to the third embodiment is configured such that, when a specific driving operation is performed on the first vehicle only in the driving state of the occupant of the first vehicle, the driving state of the occupant of the second vehicle is determined.

When at least one driver of the first vehicle and the second vehicle is performing careless driving (step ST5a-1; YES), the information generating unit 25A determines that only the driver of the first vehicle is in operation. It is determined whether careless driving has been performed (step ST5a-2). At this time, when it is determined that only the driver of the first vehicle is inadvertently driving (step ST5a-2; YES), the information generation unit 25A determines that the degree of warning is (0) (step ST5a-2). ST5a-3). The warning degree (0) corresponds to the case where the cause of the avoidance operation performed on the first vehicle is the driving state of the driver of the first vehicle. Therefore, the information generation unit 25A does not generate the warning information for the driver of the second vehicle specified by the vehicle specification unit 24, and the processing in FIG. 11 ends.

On the other hand, if it is determined that the driver who has been inadvertently driving is not the only driver of the first vehicle (step ST5a-2; NO), the information generating unit 25A determines that only the driver of the second vehicle is operating. It is determined whether careless driving has been performed (step ST5a-4). At this time, when it is determined that the driver who has been carelessly driving is not the only driver of the second vehicle (step ST5a-4; NO), that is, the driver of the first vehicle and the driver of the first vehicle at the avoidance operation time. When both drivers of the second vehicle are driving carelessly, the information generating unit 25A determines that the degree of warning is (1) (step ST5a-5). At this time, the information generation unit 25A generates warning information corresponding to the warning degree (1). For example, icon image information indicating that careless driving has occurred around the first vehicle at the avoidance operation time is generated as the warning information.

The transmission / reception unit 26 associates the warning information generated by the information generation unit 25A with the identification information of the second vehicle specified by the vehicle specification unit 24. Then, the transmission / reception unit 26 connects to the server device 3 via the communication network 4, and transmits warning information to the server device 3 (step ST6a). After that, as shown in FIG. 5B, the warning information is transmitted by the server device 3 to the vehicle-mounted device 2B of the second vehicle.

場合 When the warning degree is (1), the in-vehicle device 2B of the second vehicle presents warning information to the driver. For example, the in-vehicle device 2B displays, on the navigation screen, the icon image information indicating that careless driving has occurred around the first vehicle at the avoidance operation time. By visually recognizing this icon image, the driver of the second vehicle can recognize that the cause of the avoidance operation in the first vehicle is his own careless driving.

場合 In addition, when the warning degree is (1), as described above, the driver of the first vehicle is also performing careless driving. Therefore, the in-vehicle device 2B included in the first vehicle may display the icon image information on a screen of the navigation device included in the first vehicle. By visually recognizing the icon image, the driver of the first vehicle can recognize that the cause of the avoidance operation is his own careless driving.

When the warning degree is (2), the in-vehicle device 2B of the second vehicle displays, for example, text information indicating that the avoidance operation has been performed on the first vehicle at the avoidance operation time on the navigation screen. Or audio output. When the warning degree is (2), as described above, both the driver of the first vehicle and the driver of the second vehicle do not perform careless driving. The driver of the second vehicle can recognize that the avoidance operation has been performed on the first vehicle as a driving operation corresponding to the driving behavior of the second vehicle by visually recognizing or hearing the warning information.

When the warning degree is (3), the in-vehicle device 2B included in the second vehicle, for example, outputs image information of the second vehicle (external image information) captured from the first vehicle at the avoidance operation time. Display on the navigation screen. The driver of the second vehicle can recognize that the avoidance operation has been performed on the first vehicle by his / her own driving operation by visually recognizing this image.

As described above, the driving determination device 1B according to the third embodiment determines that the avoidance operation is performed on the first vehicle only when the occupant of the first vehicle is in the driving state. The presentation mode of the information to be transmitted to the second vehicle is changed depending on whether the occupant is only in the driving state, in both of these driving states, or in neither of the driving states. . Thus, the driver of the second vehicle can be warned in a manner according to the driving state of the driver of the first vehicle and the driving state of the driver of the second vehicle.
