Description

  The present invention relates to a driving support device, a driving support system, and a driving support method.

  Conventionally, for example, when another vehicle changes lanes to the lane of the own vehicle, there is a driving support device that notifies the other vehicle that the course is to be given. For example, the driving support device automatically determines whether or not to give the course to the other vehicle based on the positional relationship between the other vehicle and the own vehicle (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2004-13656

  However, in the conventional technology, it is determined whether or not to give up the course of another vehicle regardless of the intention of the driver of the own vehicle to give up. That is, the driver of the other vehicle cannot determine whether or not the driver of the own vehicle really gives up the course. For this reason, even if the driver of the own vehicle does not intend to give up, if the other vehicle changes lanes, the safety of the driver of the own vehicle may be reduced.

  The present invention has been made in view of the above, and an object thereof is to provide a driving support device, a driving support system, and a driving support method that can improve safety.

  In order to solve the above-described problems and achieve the object, a driving support apparatus according to the present invention includes a storage unit, a detection unit, a generation unit, and a transmission unit. The storage unit stores permission history information indicating that the driver of the host vehicle has permitted interruption of another vehicle in the past. A detection part detects the operation | movement which the said other vehicle interrupts to the lane of the said own vehicle. The generation unit generates permission information indicating a possibility that the driver of the host vehicle permits the interruption based on the permission history information when the operation is detected by the detection unit. The transmission unit transmits the permission information generated by the generation unit to the other vehicle.

  According to the present invention, safety can be improved.

  Hereinafter, embodiments of a driving support device, a driving support system, and a driving support method disclosed in the present application will be described in detail with reference to the accompanying drawings. In addition, this invention is not limited by this embodiment.

  First, the outline of the driving support method according to the embodiment will be described with reference to FIG. Drawing 1 is a figure showing an outline of a driving support method concerning an embodiment. FIG. 1 illustrates a driving support method in a scene where the host vehicle C1 and another vehicle C2 are traveling on a two-lane road. FIG. 1 shows a scene in which the turn signal is turned on as an operation in which the other vehicle C2 interrupts in advance to interrupt the lane of the host vehicle C1.

  Note that the driving support method according to the embodiment is not limited to a scene of a two-lane road, but may be a scene where the host vehicle C1 gives a course to another vehicle C2, and can be executed, for example, at a junction of a highway. It is.

  As shown in FIG. 1, the driving assistance apparatus 1 which concerns on embodiment is mounted in the own vehicle C1, and performs the driving assistance method which concerns on embodiment. In addition, an electronic device 100 that can communicate with the driving support device 1 is mounted on the other vehicle C2. Details of the electronic device 100 will be described later with reference to FIG.

  In the driving support method according to the embodiment, the driver of the own vehicle C1 permits the interruption of the other vehicle C2 based on the permission history information 31 stored in the driving assistance device 1 when the interruption operation of the other vehicle C2 is detected. The permission information indicating the possibility is generated and transmitted to the other vehicle C2.

  The permission history information 31 is information indicating that the driver of the host vehicle C1 has previously permitted an interrupt to another vehicle C2 or another vehicle other than the other vehicle C2. Details of the permission history information 31 will be described later with reference to FIG. Hereinafter, the other vehicle C2 will be described as an example.

  Here, a conventional driving support method will be described. The conventional driving support method automatically determines that the driver of the own vehicle permits the interruption of the other vehicle, that is, gives the course, based on the positional relationship between the own vehicle and the other vehicle.

  However, conventionally, there is a risk that the driver of the host vehicle may decide to give the course to the other vehicle even though the driver does not intend to give the course to the other vehicle. That is, the driver of the other vehicle cannot determine whether or not the driver of the own vehicle really gives way. For this reason, although the driver of the own vehicle has no intention of giving up the course, there is a possibility that the safety may be lowered when the driver is interrupted by another vehicle.

  Therefore, in the driving support method according to the embodiment, the driver of the host vehicle C1 notifies the other vehicle C2 of the possibility of permitting interruption before the other vehicle C2 interrupts. Specifically, the driving support apparatus 1 according to the embodiment stores in advance permission history information 31 indicating that the driver of the host vehicle C1 has previously permitted interruption of the other vehicle C2.

  Subsequently, the driving support apparatus 1 according to the embodiment detects an operation (hereinafter, an interrupt operation) in which the other vehicle C2 interrupts the lane of the own vehicle C1 (step S1). In FIG. 1, lighting of the turn signal of the other vehicle C2 is detected as an interruption operation.

  Subsequently, the driving support device 1 according to the embodiment generates permission information indicating the possibility that the driver of the host vehicle C1 permits the interruption based on the permission history information 31 when the interruption operation is detected ( Step S2).

  Subsequently, the driving support device 1 according to the embodiment transmits the generated permission information to the other vehicle C2 (electronic device 100) (step S3). For example, the electronic device 100 notifies the driver of the other vehicle C2 of the possibility that the driver of the host vehicle C1 permits the interruption, that is, the possibility of giving up the course.

  As described above, in the driving support device 1 according to the embodiment, for example, it is unlikely that the driver of the own vehicle C1 gives up the course, in other words, there is a high possibility that there is no intention to give up the driving of the other vehicle C2. If the person knows, it is possible to take measures such as interrupting the interruption. Thereby, for example, when the driver of the own vehicle C1 does not intend to give up the course, it becomes difficult to be interrupted by the other vehicle C2, and thus the safety of the driver of the own vehicle C1 can be improved.

  Note that the driving support device 1 according to the embodiment updates the permission history information 31 according to the situation in which the host vehicle C1 has given a past course, which will be described later with reference to FIGS. 4A and 4B. .

  The driving support device 1 and the electronic device 100 according to the embodiment may have the same function. That is, the driving support device 1 including the function of the electronic device 100 may be mounted on the host vehicle C1 and the other vehicle C2.

  Next, the configuration of the driving support system S including the driving support device 1 according to the embodiment will be described in detail with reference to FIG. FIG. 2 is a block diagram illustrating a configuration of the driving support system S according to the embodiment. As shown in FIG. 2, the driving support system S includes, for example, a driving support device 1 and an electronic device 100.

  The electronic device 100 is an in-vehicle device such as a navigation device, for example. The electronic device 100 is mounted on the other vehicle C2 and provides information to the driver of the other vehicle C2 based on the permission information received from the driving support device 1.

  Specifically, the electronic device 100 includes a display unit, a speaker, and the like (not shown), and displays the possibility of permitting an interrupt included in the permission information by characters or an image, or by outputting a voice, so that other vehicles Notify C2 driver.

  The electronic device 100 is not limited to the navigation device, and may be a mobile terminal such as a smartphone, a tablet terminal, a PDA (Personal Digital Assistant), or the like. Anything that can notify C2 is acceptable.

  The electronic device 100 may be the driving support device 1. That is, the driving support system S according to the embodiment may be configured by a plurality of driving support devices 1. In such a case, the driving support system S further includes a server device 200 that is communicably connected to the plurality of driving support devices 1, thereby centrally managing the permission history information 31 stored in the plurality of driving support devices 1. This point will be described later with reference to FIG.

  Moreover, it is preferable that the electronic device 100 is mounted on a vehicle having a relatively high frequency of interruption such as a taxi or a bus. When the electronic device 100 is mounted on a taxi or a bus, it is not always necessary to have the function of the driving support device 1 as long as the permission information transmitted from the driving support device 1 can be provided to the driver. As a result, the driving support system S can be configured at low cost.

  The driving support device 1 is mounted on the host vehicle C <b> 1 and is connected to the terminal device 10, the navigation device 11, the camera 12, the radar device 13, and the vehicle speed sensor 14. As described above, the driving support device 1 may be the navigation device 11. First, a configuration other than the driving support device 1 will be described.

  The terminal device 10 is, for example, a mobile terminal such as a smartphone, a tablet terminal, a PDA (Personal Digital Assistant), or the like, and stores driver information that is information related to the driver of the host vehicle C1.

  Specifically, the terminal device 10 stores driver information including identification information for personally identifying the driver of the host vehicle C1, information related to the driver's schedule, and the like. The terminal device 10 is connected to the driving support device 1 by wireless or wired and outputs driver information to the driving support device 1.

  The driving support device 1 personally authenticates the driver of the host vehicle C1 for each individual based on the identification information of the terminal device 10, but the personal authentication is not limited to the identification information of the terminal device 10, and is a driver in the vehicle. Image recognition using an image obtained by picking up images, or a method using a driving key owned by an individual may be used.

  In addition, the driving support device 1 does not necessarily need to authenticate the driver of the own vehicle C1 for each individual, and only needs to be able to authenticate that an unspecified driver has boarded the own vehicle C1.

  The navigation device 11 specifies the current position of the host vehicle C1 using radio waves from, for example, a GPS (Global Positioning System) satellite, and uses the current position and the electronic map data to guide the route to the destination. The estimated arrival time, which is the estimated arrival time at the destination, is calculated. The navigation device 11 outputs various information to the driving support device 1.

  The camera 12 is an imaging device including an imaging element such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor), and is provided at a position for imaging the situation around the host vehicle C1.

  The radar device 13 is, for example, a millimeter wave radar, and detects an object existing around the host vehicle C1. Specifically, the radar device 13 detects the presence of the other vehicle C2 traveling in front of the host vehicle C1 and the distance to the other vehicle C2. The vehicle speed sensor 14 detects the vehicle speed of the host vehicle C <b> 1 and outputs it to the driving support device 1.

  Next, the driving assistance device 1 according to the embodiment will be described. The driving support device 1 includes a control unit 2 and a storage unit 3. The control unit 2 includes a detection unit 21, an update unit 22, a determination unit 23, a generation unit 24, and a transmission unit 25. The storage unit 3 stores permission history information 31.

  Here, the driving support device 1 is, for example, a computer having various functions such as a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), a HDD (Hard Disk Drive), an input / output port, and the like. including.

  The CPU of the computer functions as the detection unit 21, the update unit 22, the determination unit 23, the generation unit 24, and the transmission unit 25 of the control unit 2, for example, by reading and executing a program stored in the ROM.

  In addition, at least one or all of the detection unit 21, the update unit 22, the determination unit 23, the generation unit 24, and the transmission unit 25 of the control unit 2 may be ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), or the like. It can also be configured with other hardware.

  The storage unit 3 corresponds to, for example, a RAM or an HDD. The RAM and HDD can store permission history information 31, information on various programs, and the like. The driving support device 1 may acquire the above-described program and various types of information via another computer or a portable recording medium connected via a wired or wireless network.

  When the other vehicle C2 detects an operation in which the other vehicle C2 interrupts the lane of the host vehicle C1, the control unit 2 generates permission information indicating the possibility that the driver of the host vehicle C1 permits the interrupt to the other vehicle C2. Send.

  The detection unit 21 detects an interruption operation that is an operation in which the other vehicle C2 interrupts the lane of the host vehicle C1. Specifically, the detection unit 21 detects an interrupt operation based on information from the camera 12 and the radar device 13.

  For example, when the distance to the other vehicle C2 detected by the captured image of the camera 12 or the radar device 13 is less than a predetermined distance, the detection unit 21 detects lighting of the blinker of the other vehicle C2 as an interrupt operation. The blinker lighting can be detected based on the change in the luminance of the blinker region extracted from the captured image by template matching or the like.

  When the distance to the other vehicle C2 is a predetermined distance or more, the detection unit 21 does not detect the interruption operation even if the blinker is turned on. That is, the detection unit 21 does not detect an interruption operation when the other vehicle C2 can change lanes even if the host vehicle C1 does not give way. As a result, unnecessary processing can be omitted, and the processing load can be reduced.

  In addition, the detection unit 21 is not limited to turning on the blinker, and may detect, for example, that the other vehicle C2 travels closer to the lane of the own vehicle C1 as an interruption operation, or may be an operation performed before the other vehicle C2 interrupts. That's fine.

  The update unit 22 updates the permission history information 31 indicating that the driver of the host vehicle C1 has permitted interruption of the other vehicle C2 in the past. Here, the processing content of the update part 22 is demonstrated concretely using FIGS. 3-4B. First, the permission history information 31 will be described with reference to FIG.

  FIG. 3 is an explanatory diagram of the permission history information 31 according to the embodiment. As shown in FIG. 3, the permission history information 31 includes items such as “detection ID”, “date and time”, “position”, and “permission flag”.

  “Detection ID” indicates information for identifying the interrupt operation detected by the detection unit 21. “Date and time” indicates the date and time when the interrupt operation is detected. “Position” indicates a position where the interrupt operation is detected, and is represented by “latitude” and “longitude”, for example. The “permission flag” is information indicating that the driver of the host vehicle C1 has permitted the interruption of the other vehicle C2.

  The update unit 22 generates a new detection ID and adds it to the permission history information 31 every time an interrupt operation is detected by the detection unit 21. That is, the total number of detection IDs corresponds to the number of detections that is the number of times that the detection unit 21 has detected an interrupt operation.

  In addition, the update unit 22 sets the permission flag to “1” when the driver of the host vehicle C1 permits the interruption of the other vehicle C2 after the detection unit 21 detects the interruption operation. That is, the total number of permission flags “1” corresponds to the number of times of permission that is the number of times that the driver of the host vehicle C1 has permitted interruption of the other vehicle C2.

  The number of detections and the number of permits described above are calculated by the generation unit 24 described later. For example, the permission history information 31 may include items of the number of detections and the number of permits in advance. Here, the processing content of the update part 22 is further demonstrated using FIG. 4A and FIG. 4B.

  4A and 4B are diagrams illustrating processing contents of the update unit 22 according to the embodiment. 4A and 4B show a scene where the host vehicle C1 and the other vehicle C2 are traveling on a two-lane road. 4A shows the processing contents when the permission flag is set to “1”, and FIG. 4B shows the processing contents when the permission flag is set to “0”.

  First, the processing contents of the update unit 22 when the permission flag is set to “1”, that is, when an interrupt is permitted, will be described with reference to FIG. 4A. As shown in FIG. 4A, it is assumed that the turn signal is turned on so that the other vehicle C2 changes the lane to the lane of the host vehicle C1.

  In such a case, permission information is generated by the generation unit 24, and the permission information is transmitted to the electronic device 100 of the other vehicle C2 by the transmission unit 25. Specific processing contents of the generation unit 24 and the transmission unit 25 will be described later. To do.

  The detection unit 21 of the driving support device 1 mounted on the host vehicle C1 detects turn-on of the blinker as an interrupt operation (step S11). Subsequently, the detection unit 21 detects that the host vehicle C1 has performed a deceleration operation based on a signal from the vehicle speed sensor 14 before the other vehicle C2 starts to change lanes (step S12). For example, the detection unit 21 detects the release of the accelerator operation or the brake operation as a deceleration operation.

  Subsequently, the update unit 22 sets the permission flag to “1” based on the detected interrupt operation and deceleration operation (step S13). That is, the update unit 22 increases the number of times of permission when the host vehicle C1 decelerates after the detection unit 21 detects the interrupt operation and before the interrupt by the other vehicle C2 is started.

  That is, the update unit 22 determines the intention to permit the interruption based on a typical behavior pattern at the time of giving a course that the driver of the host vehicle C1 decelerates when the turn signal lights up. As a result, the driver's own vehicle C1's driver's intention to give up the course can be stored as the permission history information 31, so that the possibility of permitting interruption by the generation unit 24 described later is accurately calculated. be able to.

  Note that the update unit 22 does not set the permission flag to “1” when a warning operation such as the driver of the host vehicle C1 sounding horn is detected after the turn-on of the blinker and the deceleration operation are detected. It may be set to “0”.

  This is because it can not be said that the driver of the own vehicle C1 has given up the course because the other vehicle C2 has warned that the turn signal has been turned on and forcibly interrupted. Thereby, the intention to give up by the driver of the host vehicle C1 can be more accurately stored as the permission history information 31.

  Moreover, the update part 22 may consider the eyes | visual_axis of the driver | operator of the own vehicle C1. Specifically, the update unit 22 sets the permission flag to “0” when the detection unit 21 detects turn-on of the turn signal and the line-of-sight direction detected from the driver of the host vehicle C1 does not face the turn signal. Leave.

  Next, the processing contents of the update unit 22 when the permission flag is set to “0”, that is, when the interrupt is not permitted will be described with reference to FIG. 4B. In FIG. 4B, it is assumed that the other vehicle C2 interrupts the lane of the host vehicle C1 without lighting the turn signal.

  In such a case, the detection unit 21 of the driving support device 1 mounted on the host vehicle C1 detects that the other vehicle C2 has actually interrupted the lane of the host vehicle C1 (step S21). For example, when the other vehicle C2 exceeds the center line that divides the two lanes based on the captured image of the camera 12, the detection unit 21 detects that the other vehicle C2 has interrupted.

  Subsequently, the update unit 22 sets the permission flag to “0” when the detection unit 21 detects the interruption of the other vehicle C2 (step S22). That is, the update unit 22 prohibits the update of the permitted number when the other vehicle C2 interrupts without detecting the interrupt operation by the detection unit 21.

  This is because when the other vehicle C2 forcibly cuts into the lane of the host vehicle C1, it cannot be said that the driver of the host vehicle C1 has given way. As described above, the situation where there is no choice but to give way is updated so as not to permit interruption, so that the driver's intention to give up can be more accurately reflected.

  The updating unit 22 updates the above-described number of times of permission and the number of times of detection by setting a permission flag. However, the present invention is not limited to this. For example, the update unit 22 may set a permission value, which is a relative value, according to a situation where the interruption of the other vehicle C2 is permitted, and may add and update the permission values.

  Specifically, the updating unit 22 sets the permission value relatively large when the driver of the host vehicle C1 reliably permits the interruption of the other vehicle C2. On the other hand, when the driver of the host vehicle C1 does not permit the interruption of the other vehicle C2, the update unit 22 sets the permission value relatively small.

  Next, returning to FIG. 2, the control unit 2 will be described. The determination unit 23 of the control unit 2 determines whether or not the driver of the host vehicle C1 has a margin based on the schedule of the driver of the host vehicle C1.

  Specifically, the determination unit 23 first predicts a desired arrival time that is a time to arrive at the destination based on the schedule of the day registered in the terminal device 10 owned by the driver of the host vehicle C1. Moreover, the determination part 23 acquires the arrival time to the destination calculated by the navigation apparatus 11, for example.

  The determination unit 23 determines that the driver of the host vehicle C1 has a margin when the estimated arrival time is earlier than the desired arrival time by a predetermined time or more. On the other hand, the determination unit 23 determines that there is no room when the estimated arrival time is less than the predetermined time from the desired arrival time.

  That is, the determination unit 23 determines that there is a margin when the driver of the host vehicle C1 arrives at the destination earlier than the schedule, and determines that there is no margin when the driver is behind the schedule.

  In addition, although the determination part 23 determined whether there was room based on the driver | operator's schedule of the own vehicle C1, it is not restricted to this, whether there is room based on the driving pattern of a driver | operator on the day. May be determined.

  Specifically, the determination unit 23 generates a normal driving pattern as a reference by learning in advance driving habits such as past acceleration / deceleration and steering operation of the driver. Then, the determination unit 23 determines that there is no allowance when the driving of the driver detected on that day is different from the normal driving pattern.

  Thereby, even if it is a case where a driver | operator's schedule of the day cannot be grasped | ascertained, it can be determined whether the driver | operator is driving with a margin. The degree of acceleration / deceleration can be acquired from, for example, an acceleration sensor, and the steering wheel operation can be acquired from a steering angle sensor.

  In addition, the determination unit 23 is not limited to the driver's driving habits, for example, whether or not there is room depending on whether biological information such as heart rate and body temperature, information on the driver's line-of-sight pattern and behavior, etc. is different from normal. It is good also as determining. As a result, it can be determined that there is no room when the driver is in poor physical condition or is driving with tension.

  Moreover, the determination part 23 determines with no margin, for example, when a driver | operator is driving continuously for the predetermined time or more. This is because it is assumed that the driver is tired from driving for a long time, so that the concentration on driving is lower than usual, that is, the driver is driving casually.

  When the detecting unit 21 detects an interrupt operation, the generating unit 24 displays permission information indicating a possibility that the driver of the host vehicle C1 permits the interrupt based on the permission history information 31 stored in the storage unit 3. Generate.

  Specifically, the generation unit 24 calculates the possibility of permitting an interrupt using the above-described detection count and permit count included in the permit history information 31. More specifically, the generation unit 24 calculates the ratio of the number of times of permission to the number of times of detection as the possibility of permission as described above.

  Thereby, if permission information is transmitted to the other vehicle C2 by the transmission part 25 mentioned later, it can be judged easily whether the driver | operator of the other vehicle C2 can interrupt. Note that the calculation of the possibility of permitting an interrupt by the generation unit 24 is not limited to the method using the detection count and the permit count.

  For example, when the permission value described above is calculated by the update unit 22, the generation unit 24 may calculate the possibility of permitting an interrupt based on the permission value.

  The generation unit 24 may generate permission information based on the permission history information 31 corresponding to the current position of the host vehicle C1. Specifically, the generation unit 24 uses the detection ID of the “position” (see FIG. 3) within a predetermined distance from the current position of the host vehicle C1 in the permission history information 31 to allow the above-described possibility of permission. It may be calculated.

  As a result, the generation unit 24 can generate permission information according to, for example, regional characteristics (prefectures, municipalities, etc.) and place characteristics (near intersections, straight roads, etc.), so more accurate interruption is permitted. The possibility of doing can be calculated.

  In addition, when the determination unit 23 determines that the driver of the host vehicle C1 has no room, the generation unit 24 may generate permission information that has been corrected to reduce the possibility of permission. This takes into account that when the driver of the host vehicle C1 is in a hurry, the possibility of giving up the course is low.

  In this way, the generation unit 24 can cause the driver of the other vehicle C2 to refrain from interrupting by reducing the possibility of permitting when the driver has no allowance. Irritation can be reduced.

  The transmission part 25 transmits the permission information produced | generated by the production | generation part 24 to the electronic device 100 of the other vehicle C2 by vehicle-to-vehicle communication, for example.

  Next, the processing procedure of the generation process executed by the driving support device 1 according to the embodiment will be described with reference to FIG. FIG. 5 is a flowchart illustrating a processing procedure of generation processing executed by the driving support device 1 according to the embodiment.

  As shown in FIG. 5, first, the detection unit 21 detects an interruption operation in which the other vehicle C2 interrupts the lane of the host vehicle C1 (step S101).

  Subsequently, when the detecting unit 21 detects an interrupting operation, the generating unit 24 is based on the permission history information 31 indicating that the driver of the own vehicle C1 has permitted the interruption of the other vehicle C2 in the past. The permission information indicating the possibility that the driver of C1 permits the interruption is generated (step S102).

  Subsequently, the determination unit 23 determines whether or not the driver of the host vehicle C1 has a margin based on the schedule of the driver of the host vehicle C1 (step S103). The transmission part 25 transmits permission information to the electronic device 100 of the other vehicle C2 (step S104), when the determination part 23 determines with the driver | operator of the own vehicle C1 having a margin (step S103, Yes). The process ends. That is, the generation unit 24 does not correct the possibility of permission.

  On the other hand, in step S103, when the determination unit 23 determines that the driver of the host vehicle C1 has no room (No in step S103), the generation unit 24 corrects to reduce the possibility of permitting an interrupt (step S103). (S105), the process proceeds to step S104.

  Next, a processing procedure of update processing executed by the driving support device 1 according to the embodiment will be described with reference to FIG. FIG. 6 is a flowchart illustrating a processing procedure of update processing executed by the driving support device 1 according to the embodiment.

  As shown in FIG. 6, first, the detection unit 21 detects an interruption operation in which the other vehicle C2 interrupts the lane of the host vehicle C1 (step S201). When detecting the interrupt operation (Yes at Step S201), the detection unit 21 determines whether or not the host vehicle C1 has decelerated until the interrupt of the other vehicle C2 is started (Step S202).

  The update part 22 updates the permission frequency of the permission history information 31 memorize | stored in the memory | storage part 3, when the deceleration operation of the own vehicle C1 is detected by the detection part 21 (step S202, Yes) (step S203, Yes). The process is terminated.

  On the other hand, in step S201, the detection part 21 determines whether the other vehicle C2 interrupted, when not detecting an interruption operation (step S201, No) (step S204).

  If the detecting unit 21 detects that the other vehicle C2 has interrupted without detecting the interrupting operation (step S204, Yes), the updating unit 22 prohibits the updating of the permitted number (step S205). The process ends.

  On the other hand, in step S202, the update part 22 transfers a process to step S205, when the deceleration of the own vehicle C1 is not detected by the detection part 21 (step S202, No).

  On the other hand, in step S204, the detection part 21 transfers a process to step S201, when the other vehicle C2 has not interrupted (step S204, No).

  As described above, the driving assistance apparatus 1 according to the embodiment includes the storage unit 3, the detection unit 21, the generation unit 24, and the transmission unit 25. The memory | storage part 3 memorize | stores the permission log information 31 which shows that the driver | operator of the own vehicle C1 permitted interruption of the other vehicle C2 in the past. The detection unit 21 detects an operation (interrupt operation) in which the other vehicle C2 interrupts the lane of the host vehicle C1. The generation unit 24 generates permission information indicating the possibility that the driver of the host vehicle C1 permits interruption based on the permission history information 31 when the detection unit 21 detects an interruption operation. The transmission unit 25 transmits the permission information generated by the generation unit 24 to the other vehicle C2. Thereby, the safety | security of the driver | operator of the own vehicle C1 can be improved.

  In the above-described embodiment, the driving support system S according to the embodiment includes the driving support device 1 and the electronic device 100. However, the present invention is not limited to this, and the driving further includes the server device 200. Support system S may be sufficient. This point will be described with reference to FIG.

  FIG. 7 is a block diagram illustrating a configuration of a driving support system S according to a modified example of the embodiment. As illustrated in FIG. 7, the driving support system S according to the modification of the embodiment includes a plurality of driving support devices 1 and a server device 200.

  The server device 200 is communicably connected to the plurality of driving support devices 1, and synchronizes with the permission history information 31 stored in each driving support device 1, thereby centralizing the permission history information 31 of each driving support device 1. To manage.

  The server device 200 can generate permission information based on the permission history information 31 collected from the plurality of driving support devices 1 and transmit the permission information to the driving support device 1. For example, the server device 200 generates permission information based on a position corresponding to the current position of the vehicle C.

  That is, the server device 200 calculates the possibility of more accurate permission by calculating how much concession has been made in the past at the position based on the permission history information 31 collected from the plurality of driving support devices 1. Can do.

  As described above, by obtaining the permission information from the server device 200, for example, when the driving support device 1 is mounted only on the vehicle C to be transferred, that is, the driving support device 1 is mounted on the vehicle C to be transferred. Even if it is not done, it is possible to judge the possibility of having it handed over.

  Each driving support device 1 transmits the updated permission history information 31 to the server device 200 when the permission history information 31 is updated. The driving support device 1 may store only the latest permission history information 31 by sequentially deleting the old permission history information 31 when updating the permission history information 31. Thereby, the storage capacity can be suppressed.

  In addition, each driving support device 1 stores the permission history information 31 associated with “position” or the like in the server device 200, and the own storage unit 3 includes only a “detection ID” and a “permission flag”. The history information 31 may be stored. Thereby, it is possible to calculate the possibility of permitting an interrupt while suppressing the storage capacity.

  Further effects and modifications can be easily derived by those skilled in the art. Thus, the broader aspects of the present invention are not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications can be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
