The operation is automatically controlled based on the information obtained. Vehicles may broadly include vehicles such as passenger cars and trucks, motorcycles, and the like, which move on the road by rotating wheels by a prime mover. In addition, the level of automatic driving related to these vehicles is not particularly limited, and for example, level 1 (acceleration, steering, braking) in general leveling defined by NHTSA (National Highway Traffic Safety Administration) etc. It shall include everything from (operated by the system) to level 4 (fully automatic driving in which the driver is not involved in all acceleration, steering, and braking) that is not in actual operation at this time.

<System configuration>
FIG. 1 is a diagram showing an outline of a configuration example of a vehicle driving support system according to a first embodiment of the present invention. The vehicle driving support system 1 includes devices such as an ECU (Electronic Control Unit) 10 mounted on the vehicle 2, various sensors 20, a drive recorder (vehicle-mounted camera) 30, and a car navigation system 40.

The ECU 10 is a device that electronically controls the operation of each part of the vehicle 2, and is implemented by, for example, hardware including a semiconductor integrated circuit such as a microcomputer (not shown) or software executed by a CPU (Central Processing Unit) (not shown). It has each part such as a communication unit 11 and an operation control unit 12.

The communication unit 11 has a function of making a general Internet connection by wireless communication (mobile communication, short-range wireless communication, etc.), and performing vehicle-to-vehicle communication and road-to-vehicle communication using a predetermined protocol. In vehicle-to-vehicle communication, information related to the driving situation can be exchanged with another vehicle or the like 2'which also has a vehicle-to-vehicle communication function according to a predetermined protocol. The other vehicle 2'includes, in addition to the vehicle, a pedestrian who holds a device capable of communicating with the vehicle 2 by a predetermined protocol for vehicle-to-vehicle communication, such as a smartphone or a dedicated device. It shall be possible.

Further, in road-to-vehicle communication, information related to the driving status, traffic status, etc. of the vehicle 2 can be exchanged with the road equipment 3 having a communication function. The road equipment 3 may include, for example, buildings and the like in addition to equipment related to traffic such as traffic lights, road signs, roads, and guardrails. Moreover, these are not limited to those installed publicly, and may be installed by the private sector. The data exchanged by road-to-vehicle communication via the road equipment 3 is generated or recorded by, for example, a traffic control system 50 or the like, which is an information processing system that collects and manages traffic information and provides it to each vehicle 2. May be good. Further, the data to be exchanged is not limited to the data related to the situation such as the driving situation and the traffic situation, and may be, for example, the data related to the driving instruction generated by the instruction unit 51 of the traffic control system 50.

The operation control unit 12 has a function of operating and controlling the operation of the vehicle 2, including automatic operation. You may also control the operation of devices such as the communication unit 11, the sensor 20, and the drive recorder 30. In the operation control, for example, the control content is appropriately changed based on the information acquired via the communication unit 11, the sensor 20, and the like. At this time, as will be described later, for example, the control content may be determined by referring to a control rule 13 or a traffic rule 14 which is set in advance or dynamically in a recording medium such as a memory (not shown). good.

The ECU 10 may have various other control functions (for example, engine control for improving fuel efficiency) that contribute to the operation of the vehicle 2 (for example, engine control for improving fuel efficiency), but FIG. 1 is related to the present embodiment. Only each part to be described is described.

The sensor 20 is a known device that detects various situations related to the vehicle 2. For example, a vehicle speed sensor, an acceleration sensor, a gyro sensor, a temperature sensor, a pressure sensor, a GPS (Global Positioning System) sensor, an infrared sensor, and an optical sensor. Various things such as can be targeted. The data detected by the sensor 20 is sent to, for example, the ECU 10 and can be used when the operation control unit 12 determines the control content or can be used for the route search of the car navigation system 40.

The drive recorder 30 has a function of acquiring and recording the situation outside or inside the vehicle as video and audio by an in-vehicle camera as a record of driving including the time of an accident. Here, a commercially available drive recorder can be used as appropriate. The ECU 10 may instruct control such as start / end of recording. Recording may be continued at all times regardless of the presence or absence of instructions.

The car navigation system 40 is a general car navigation system that searches for a route to a destination in response to an instruction from the driver and provides route guidance based on information on the current position of the vehicle 2. The car navigation system 40 provides route guidance to the driver via a display means (not shown) such as a display installed in the vehicle or an in-vehicle head-up display that projects an image onto the windshield by a projector. Further, the ECU 10 and the like can display various other information related to the operation control via the display means.

<Driving control (adjustment between vehicles)>
When it is detected that an accident such as a collision or contact with another vehicle 2'is likely to occur while the vehicle 2 is operating by automatic driving, in order to avoid the occurrence of an accident, for example, the vehicle is automatically driven. It is conceivable to perform control such as stopping 2 or changing the course. Here, when the other vehicle, etc. 2'of the other party is also automatically driving, it is conceivable that the other vehicle, etc. 2'also performs driving control in order to avoid the occurrence of an accident. As a result, it is assumed that the avoidance control conflicts and an accident occurs, for example, both vehicles change their course in the same direction. Therefore, in the present embodiment, the avoidance control for avoiding the occurrence of an accident is adjusted in advance so as not to compete with each other by the vehicle-to-vehicle communication between the vehicle 2 and the other vehicle 2'.

FIG. 2 is a diagram showing an outline of an example of automatic operation control in the present embodiment. Here, as shown in the upper figure, when the possibility of a collision accident becomes high when the vehicle 2 and the other vehicle 2'are traveling opposite each other by automatic driving, in advance. An example in which one (other vehicle 2'in the example of FIG. 2) changes the course and the other (vehicle 2 in the example of FIG. 2) automatically drives to maintain the same course by adjusting the avoidance control. Is shown.

The lower figure is a flowchart showing an outline of an example of a process flow for adjusting avoidance control by vehicle-to-vehicle communication. First, the vehicle 2 establishes a vehicle-to-vehicle communication session with a other vehicle or the like 2'by the communication unit 11 using a predetermined protocol (S01). After that, information on the driving situation (current position, traveling direction, speed, etc.) and the content of the control rule 13 are exchanged with the other vehicle 2'by vehicle-to-vehicle communication (S02). Then, the driving control unit 12 determines whether or not the own vehicle has the adjustment right according to a predetermined rule (S03). The predetermined rule may be any rule that can uniquely identify one of the vehicles. For example, a rule such as one having a small vehicle ID, one having a current position in the north, or one having a high speed can be appropriately set.

If the own vehicle (vehicle 2) does not have the adjustment right in step S03 (S03: No), the adjustment result from the other party (other vehicle, etc. 2') is awaited and received (S07) without doing anything in particular. ). If the own vehicle (vehicle 2) has the adjustment right (S03: Yes), the possibility of an accident increases based on the information on the driving status of both vehicles and the contents of control rule 13. It analyzes what the avoidance control will be (S04), and determines whether or not they compete with each other (for example, both vehicles change their course in the same direction) (S05).

If the avoidance controls of both vehicles do not conflict in step S05 (S05: No), that is, if the accident can be avoided as it is, the other vehicle, etc. 2'will be notified as an adjustment result without adjusting the avoidance control. Send (S07). When the avoidance control conflicts (S05: Yes), the content of the avoidance control of either one or both vehicles is adjusted so as not to conflict based on a predetermined rule (S06), and the adjustment result is adjusted to the other vehicle, etc. 2'. (S07). For example, when both vehicles change their course in the same direction, the content of avoidance control is changed so that one of them changes its course in the opposite direction.

The rules for how to change the avoidance control of the vehicle 2 and the other vehicle 2'are not particularly limited. For example, one of them may be set as a priority vehicle, the current driving situation may be prioritized, and the content of the avoidance control of the other may be changed based on this. At this time, as parameters used when determining the priority vehicle, for example, the driving situation such as speed may be used, the age and years of driving of the driver, the number and attributes of passengers, the model and year of both vehicles, and the like. Acquirable attribute information such as the attributes of both vehicles and the attributes of the current location, such as the slope of the road (up or down) and the condition of the road shoulder (presence or absence of sidewalks, cliffs, etc.) may be used. In this case, for example, the one whose avoidance control is difficult is determined based on the driving situation and these attribute information, and this is set as the priority vehicle. Further, the content of the avoidance control of both vehicles may be uniformly adjusted based on a predetermined rule regardless of the driving status of both vehicles and various attribute information.

The changed avoidance control rule may be reflected by overwriting the content (default control content) set in the control rule 13, or is temporarily limited to the target other vehicle, etc. 2'. It may be treated as a default setting.

FIG. 3 is a diagram showing an outline of another example of automatic operation control in the present embodiment. Here, as shown in the upper figure, when one side (vehicle 2 in the example of FIG. 3) tries to enter a merging / branching point of a road such as a T-junction or an intersection by automatic driving, the same merging / branching occurs. Avoid accidents such as collisions by unilaterally controlling the automatic driving of the other (other vehicles, etc. 2'in the example of Fig. 3) trying to enter the point by inter-vehicle communication (stopping or decelerating in the example of Fig. 3). An example of the case is shown.

The lower figure is a flowchart showing an outline of an example of a processing flow for controlling the other automatic driving by vehicle-to-vehicle communication. First, the vehicle 2 establishes a vehicle-to-vehicle communication session with a other vehicle or the like 2'by the communication unit 11 according to a predetermined protocol (S11). After that, a request for controlling automatic driving is transmitted to another vehicle or the like 2'(S12). Although not shown, the other vehicle or the like 2'that has received this request responds whether or not to allow the control by the vehicle 2 based on a predetermined rule.

The vehicle 2 receives the response from the other vehicle, etc. 2'(S13), and determines whether or not the other vehicle, etc. 2', which is the other party, allows the control by the vehicle 2 (S14). If the other vehicle or the like 2'does not allow the control by the vehicle 2 (S14: No), the control of the other vehicle or the like 2'is not performed. When control is permitted (S14: Yes), the control content of automatic driving (for example, stopping or decelerating) is transmitted to another vehicle or the like 2'(S15). Then, assuming that the other vehicle or the like 2'is automatically driven based on the control content, the control content of the automatic driving of the own vehicle is changed as necessary (S16). For example, enter the confluence / branch point as it is without stopping. Regarding the transmission content in step S15, step S16 may be executed with the reception of Ac from another vehicle or the like 2'as a trigger.

In the example of FIG. 3, the case of avoiding an accident such as a collision at a merging / branching point is taken as an example, but it can also be applied to control for realizing smooth traffic such as avoiding traffic congestion.

FIG. 4 is a diagram showing an outline of another example of automatic operation control in the present embodiment. Here, as shown in the upper figure, an example in which the vehicle 2 and a plurality of other vehicles 2'following are logically connected, managed as an integrated group, and automatic driving control and traffic control are performed for the group. Is shown. For example, each vehicle belonging to a group can be connected to move / guide to the same destination by automatic driving, or control of the operation of road equipment 3 such as a traffic light can be requested so that each vehicle belonging to the group can move as a unit. can do.

The lower figure is a flowchart showing an outline of an example of a processing flow for controlling automatic driving, operation of a traffic light, etc. for each vehicle belonging to a group by vehicle-to-vehicle communication or road-to-vehicle communication. First, the vehicle 2 starts a loop process in which the following other vehicles 2'are processed in order from the vehicle 2 (S21). In the loop processing, first, a session of vehicle-to-vehicle communication using a predetermined protocol is established by the communication unit 11 with the target other vehicle or the like 2'(S22). Then, various information related to the driving status of the vehicle 2 and the target other vehicle 2'is acquired (S23).

After that, based on the information acquired in step S23, it is determined whether or not the distance between the vehicle 2 and the target other vehicle or the like 2'is within a predetermined distance (S24). The predetermined distance here is a value preset as an upper limit of the length of the convoy when managing the vehicle 2 and a plurality of other vehicles 2'as a group. When the distance between the target other vehicle and the like 2'is larger than the predetermined distance (S24: No), the loop processing is terminated.

If the distance between the target other vehicle, etc. 2'is within the predetermined distance (S24: Yes), whether the driving situation is similar between the target vehicle 2 and the target other vehicle, etc. 2'. That is, it is determined whether or not it is suitable for management as a group (S25). The similar determination method is not particularly limited, but for example, it can be determined based on whether or not each item such as the traveling direction, the (average) speed, and the destination set in the car navigation system 40 is similar. If the operating conditions are not similar (S25: No), the loop processing is terminated.

When the driving conditions are similar (S25: Yes), the target other vehicle 2'is added to the group to which the vehicle 2 belongs and the setting is made to manage as a group (S26). The fact that the group has been set is notified, for example, to the target other vehicle 2'by vehicle-to-vehicle communication together with information such as the group ID and the ID that identifies the vehicle 2. After that, the processing for the target other vehicle, etc. 2'is completed, and the process proceeds to the next processing for the other vehicle, etc. 2'(S27, S21). When processing is performed on all following vehicles having similar driving conditions within a predetermined distance, the loop processing ends.

After that, the automatic driving control and traffic control of the group are performed on the vehicle 2 belonging to the set group and the other vehicle 2'(S28). For example, the information related to the driving content of the vehicle 2 is notified to other vehicles 2'in the group by vehicle-to-vehicle communication in real time. The other vehicle, etc. 2'controls automatic driving so as to follow the vehicle 2 according to the acquired driving content. Further, for example, the vehicle 2 and each other vehicle 2'notify the group ID to which the vehicle 2 belongs to the road equipment 3 (traffic light) by road-to-vehicle communication. The road equipment 3 (traffic light) may continue the green light until all other vehicles such as 2'with the same group ID as the group ID of the vehicle 2 have passed.

While the group control of the vehicle 2 and the other vehicle 2'is continued, it is periodically determined whether or not each other vehicle 2'in the group has left the group (S29). Whether or not the group has left the group can be determined, for example, by the same criteria as the determination criteria in steps S24 and S25 described above. If there is no other vehicle or the like 2'that has left (S29: No), the process returns to step S28 to continue group control. If there is another vehicle, etc. 2'that has left, the control in the group is terminated. The control of the group is terminated only between the other vehicle, etc. 2'that has left the vehicle and the other vehicle, etc. 2'that follows it, and the other vehicle, etc. 2'that remains closer to the vehicle 2 than the other vehicle, etc. 2'that has left the vehicle. Group control may be continued between.

In the example of FIG. 4, the vehicle 2 is at the head of the group's convoy, and the following other vehicles 2'are managed as a group to follow the vehicle 2 (vehicle 2 is the leader of the group). However, it is not limited to this. The vehicle 2 that is the leader of the group does not have to be located at the head of the convoy, and the group may be set for other vehicles such as 2'in front of and behind the vehicle 2. Further, in the example of FIG. 4, it is assumed that the vehicle 2 directly communicates with each other vehicle 2', but the present invention is not limited to this. Another vehicle or the like 2'in which a session of vehicle-to-vehicle communication with the vehicle 2 has been established may further perform vehicle-to-vehicle communication with the following other vehicle or the like 2'and relay data in a sequential connection form.

<Operation control (overall control in an emergency)>
FIG. 5 is a diagram showing an outline of another example of automatic operation control in the present embodiment. Here, for example, in the event of an emergency such as a disaster, the automatic driving of each vehicle 2 is forcibly controlled in order to ensure the safety of each vehicle 2 and drivers, pedestrians, etc., and smooth evacuation / movement. An example is shown. For example, the traffic control system 50 operated and managed by the national government, local governments, etc. transmits an instruction related to the control content to each vehicle 2 in automatic driving by road-to-vehicle communication via the road equipment 3 by the instruction unit 51. Each vehicle 2 may independently receive a disaster signal or the like, and the operation control unit 12 may autonomously change the control content for emergencies according to a predetermined rule.

The content of control in an emergency such as a disaster is not particularly limited, but for example, in order to prevent a new inflow of the vehicle 2 into the center of the city and immediately alleviate the traffic congestion in the center, for example, FIG. As shown in the above, the automatic operation is controlled so that the vehicle 2 located at the outer edge (suburb) of the urban area is forcibly moved to the outside of the urban area. After that, the vehicle 2 to be forcibly moved to the outside of the city area is gradually expanded toward the center of the city area. Free driving is also restricted for the vehicle 2 that is made to wait for movement to the outside of the city area during that time. For example, the speed limit may be set lower than usual, or the movement toward the center of the city may be restricted.

Further, some vehicles 2 located in the central portion or the like may be moved to a safe place such as a shoulder and automatically parked and stopped. It should be noted that the same automatic parking / stopping control is performed not only when a disaster occurs, but also when, for example, when the driver detects a situation in which normal driving is not possible due to drinking alcohol, falling asleep, etc., the same automatic parking / stopping control is performed according to the time of a disaster. good.

For the vehicle 2 that does not have the automatic driving function, for example, when the vehicle 2 has the functions of vehicle-to-vehicle communication and road-to-vehicle communication, the vehicle is based on the information that can be exchanged by these communications. The position of 2 is specified, and the driver is notified of the instruction related to the control content. The means of notification is not particularly limited, but for example, it can be reflected in the route guidance of the car navigation system 40, or the instruction content can be displayed on the display. The instruction content may be output by voice. For the vehicle 2 that does not have a communication function, for example, the existence, position, driving status, etc. of the vehicle 2 are specified and grasped by a satellite photograph or the like. Then, when it is determined that the behavior is contrary to the control content in an emergency, it is possible to take measures such as directing a corresponding vehicle such as a police vehicle or a tow truck to the site.

<Operation control (in case of communication failure)>
FIG. 6 is a diagram showing an outline of an example of communication control of the vehicle 2 in the present embodiment. Here, as shown in the upper figure, an example of control when the vehicle 2 in automatic driving cannot communicate in whole or in part due to a communication failure, a system failure, or the like is shown in the lower figure. .. For example, as shown in the figure on the left side of the lower row, when communication becomes impossible, the vehicle 2 normally indicates the content and mode of automatic driving (in the figure, it is represented by the difference in the color and length of the arrows). Switch from one to another. For example, switch to control content that emphasizes safety. You may switch from automatic operation to manual operation (non-automatic operation).

In addition, in the case of "when communication becomes impossible", in addition to the case where communication by the mobile communication system provided by the mobile communication operator becomes impossible, a plurality of types of mobile communication systems provided by the mobile communication operator are used. This includes cases where communication using some of these methods is no longer possible. For example, at a certain timing, the communication unit 11 was able to communicate with each of the 3rd to 5th generation mobile communication systems (3G, 4G, 5G), but at the next timing, only 5G communication may not be possible. include. At this time, the content and mode of the automatic operation may be switched according to the communication method at the timing when the communication method is switched. For example, as shown in Tables 1 and 2 below, it is possible to switch to an operation mode corresponding to the communication method.

In the example of Table 1, the automatic operation mode, the semi-automatic (partially automatic) operation mode, and the manual (non-automatic) operation mode are switched according to the communication method. Further, in the example of Table 2, two types of automatic operation modes (“automatic operation 1” and “automatic operation 2”) having different contents and settings and semi-automatic (partially automatic) operation modes are switched depending on the communication method. There is.

When switching to manual driving, the control of switching may be different depending on whether or not the person on board the target vehicle 2 has a driver's license. For example, when detecting a communication failure and switching to manual driving, ask the passenger whether or not he / she has a driver's license through the display of the car navigation system 40, or in the case of an IC card type driver's license, an IC chip. Have the reader read the contents of. Then, if the passenger has a valid driver's license, he / she switches to manual driving, while if he / she does not have a valid driver's license, the vehicle 2 is automatically driven to an appropriate place in the neighborhood so as not to interfere with the surrounding traffic. To move / stop.

As shown in the lower center diagram of FIG. 6, the vehicle 2 may switch the communication connection destination to another server, system, or the like. Further, as shown in the figure on the right side of the lower row, even if the vehicle 2 cannot communicate with the server, the system, etc., the vehicle-to-vehicle communication with the other vehicle, etc. 2'is possible, and the other vehicle, etc. 2' If it is possible to communicate with the server, system, etc., it may communicate with the server, system, etc. via the other vehicle, etc. 2', or continue automatic driving under the control of the other vehicle, etc. 2'. ..

FIG. 7 is a diagram showing an outline of an example of route guidance based on the communication method (operation mode) in the present embodiment. As described with reference to FIG. 6 above, in the present embodiment, when the communication method of the mobile communication system is switched in the vehicle 2, the content and mode of automatic driving can be switched. The area map of each communication method is published by each mobile communication operator. Therefore, using the publicly available area maps of each communication method and the map information held by the car navigation system 40, the car navigation system 40 may be configured to provide route guidance based on the communication method (that is, the corresponding driving mode). can.

For example, if the driver requests the car navigation system 40 to provide route guidance when going from the departure point to the destination in the automatic driving mode, and the control in Table 1 above is applied, the automatic driving mode is , It is set only when the communication method is 5G communication. Therefore, a route that can be used for 5G communication on all routes to the destination can be calculated using the area map of 5G communication and the map information held by the car navigation system 40 and presented to the driver.

For example, in the grid-like road map shown in FIG. 7, an area where 5G communication is possible and an area where 4G communication is possible are superimposed and shown. Here, when searching for a route from the departure house (lower right) to the destination hospital (upper left) in the figure, if the driver specifies the automatic driving mode, the car navigation system 40 can perform 5G communication. Extract the route from the starting point to the destination (the route indicated by the dotted arrow in the figure) on a simple road. If the communication method is not limited, there is a route that can reach the destination in a shorter distance and in a shorter time than the route indicated by the dotted arrow above, but it is a roundabout because the driver specified the automatic driving mode. Is extracting a route that can maintain 5G communication.

The area map published by the mobile communication operator does not always show the correspondence status of each communication method in detail along the road. In this case, for example, an area map along the road may be separately prepared by a server system such as a vehicle driving support server, which will be described later, and distributed to the vehicle 2. For example, it is possible to collect information on the status of each communication method for each area where each driver is located and create an area map of the communication method on each road in the area.

Further, the radio wave condition in each communication method may change from moment to moment, such as when the weather such as rain or when the beam formation by the Massive MIMO antenna is dynamically changed. Technology that predicts that the communication method to be used will change in response to such dynamic changes in radio wave conditions on the device side (terminal side) and mobile communication system side, and changes in communication method on the mobile communication system side Many notification technologies have already been published. Therefore, a configuration may be configured in which a change in the communication method is detected in advance on the vehicle 2 (car navigation system 40) side and a route search is performed again by using such a well-known conventional technique.

On the contrary, even if the route that corresponds only to the automatic driving mode and / or the semi-automatic driving mode is extracted in the first route search, and the route that increases the driving distance and the driving time is extracted, the radio wave is transmitted after that. The situation may change. In this case, it may be possible to maintain the communication method required by the automatic operation mode and / or the semi-automatic operation mode even on a route having a shorter operation distance or operation time. Therefore, the radio wave condition may be detected at any time, the route search may be performed again with the change in the radio wave condition as a trigger, and a new route may be proposed to the driver.

<Driving control (traffic rule compliance)>
In the automatic driving of the vehicle 2, it is necessary to control the driving content so as to comply with the traffic regulations and the traffic rules stipulated as traffic manners. Such traffic rules may be different in each region in addition to those set uniformly nationwide. In the present embodiment, these rules are stored in advance on a table or the like as, for example, traffic rule 14. Regarding rules that differ from region to region and temporary rules such as in an emergency, those instructed each time from a system such as the traffic control system 50 or a server via road-to-vehicle communication or the like may be retained. In addition to the rule itself, the traffic rule 14 may include information on roads and areas (for example, parking prohibited sections) to which the rule is applied. Further, the control content of the automatic driving when the traffic rule is applied may be set separately in the control rule 13.

The traffic rule 14 and the control rule 13 when this is applied include, for example, compliance with the speed limit (the driver cannot adjust the speed without permission), prohibition of overtaking in the overtaking prohibited section, and in a driving section such as near a school. This includes slow driving, avoidance of one-way sections and prohibited sections. Further, when entering a parking prohibited section, the driver may be warned through, for example, display on the display of the car navigation system 40, voice output, or the like, and control may be made so that parking is not possible (stopping is possible). In addition, in a stop-prohibited section such as in front of a fire station, for example, when entering, there is no other vehicle 2'in front based on information such as vehicle-to-vehicle communication, road-to-vehicle communication, and camera image of the drive recorder 30. It may be controlled to enter only when it is determined that the vehicle can pass without stopping.

FIG. 8 is a flowchart showing an outline of an example of a flow of operation control according to the traffic rule 14 in the present embodiment. First, the operation control unit 12 of the vehicle 2 acquires the control rule 13 (S31). Then, based on the information obtained by the vehicle-to-vehicle communication and the road-to-vehicle communication by the communication unit 11 and the information obtained from the sensor 20, information related to the current position of the vehicle 2 and the attributes of the road in operation is acquired (S32). ). Then, the traffic rule 14 applied to the current position and the road on which the vehicle is traveling is acquired (S33). Further, based on the information obtained from the sensor 20, information on the driving status (speed, traveling direction, driving mode, etc.) of the vehicle 2 is acquired (S34).

After that, it is determined whether or not the vehicle is in automatic operation (S35). When automatic driving is in progress (S35: Yes), automatic driving is controlled based on the control rule 13 and the traffic rule 14 acquired in steps S31 and S33, respectively (S37). That is, autonomous driving is controlled in a manner that complies with traffic regulations and traffic manners. When the vehicle is not in automatic driving (S35: No), it is determined from the driving status information acquired in step S34 whether or not the rule deviated from the rule defined in the traffic rule 14 (S36). If the rule is not deviated (S36: No), the process ends without doing anything. On the other hand, if the rule is deviated (S36: Yes), the automatic driving is forcibly controlled based on the control rule 13 and the traffic rule 14 acquired in steps S31 and S33, respectively (S37). In other words, it will forcibly switch to automatic driving control in a form that complies with traffic regulations and traffic manners.

<Operation control (when an accident occurs)>
FIG. 9 is a flowchart showing an outline of an example of the flow of operation control when an accident occurs in the present embodiment. First, the operation control unit 12 of the vehicle 2 acquires information on the driving status of the vehicle 2 (speed, traveling direction, video information outside the vehicle obtained by the drive recorder 30 or the like, etc.) based on the information obtained from the sensor 20. (S41). Then, the acquired information is analyzed to predict the possibility of an accident (S42). The method of predicting an accident is not particularly limited, but for example, the braking distance is estimated based on the speed of the vehicle 2, the weather, the road surface condition, etc., and the braking distance of the other vehicle 2'or the road is within the range of the braking distance in the traveling direction of the vehicle 2. Predict based on whether or not there are obstacles such as equipment 3 and buildings. Ease of avoidance operations based on road conditions, such as the width and slope of the road and the presence or absence of sidewalks, may be considered. It is desirable to numerically express the possibility of an accident.

After that, it is determined whether or not an accident is likely to occur, that is, whether or not the possibility of an accident is higher than a predetermined degree (S43). If an accident is unlikely to occur (S43: No), the process is terminated and the automatic operation is continued as it is. If an accident is likely to occur (S43: Yes), the acquisition of the image around the vehicle 2 is started (S44). This can be used when the drive recorder 30 constantly acquires images. A system or service that takes a satellite image or acquires an image may be requested to acquire the satellite image or the image via the communication unit 11.

After that, based on the information obtained from the sensor 20, it is determined whether or not the accident occurrence is actually detected (S45). If it is not detected (S45: No), the process is terminated and the automatic operation is continued as it is. When it is detected (S45: Yes), the accident occurrence is notified to the police, etc. via the communication unit 11 (specifically, the system that accepts accident reports at the police (hereinafter, may be referred to as "police system")). Notify (S46). After the notification (may be before the notification), the information of the video captured by the drive recorder 30 is acquired (S47), this is transmitted to the police system (S48), and the process is terminated.

The video information to be transmitted is not limited to the video information of the drive recorder 30 of the vehicle 2, and may be the video information of the drive recorder 30 of another vehicle or the like in the vicinity acquired by inter-vehicle communication. Further, instead of the vehicle 2 actively transmitting the video information, the vehicle 2 may transmit the information based on the recovery instruction from the police system that has been notified of the occurrence of the accident.

As described above, according to the vehicle driving support system 1 according to the first embodiment of the present invention, the vehicle 2 having the automatic driving function is targeted at other vehicles 2', road equipment 3, servers and systems. Information can be exchanged via communication with the vehicle, and the operation can be automatically controlled based on the acquired information.

(Embodiment 2)
The vehicle driving support system according to the second embodiment of the present invention provides the driver or passenger of the vehicle 2 (either during automatic driving or manual driving) to the driver or passenger via the car navigation system 40 or its display or the like. It presents useful information.

<System configuration>
FIG. 10 is a diagram showing an outline of a configuration example of a vehicle driving support system according to a second embodiment of the present invention. Since the configuration is substantially the same as that shown in FIG. 1 of the first embodiment, the description will be mainly limited to the differences. In the vehicle driving support system 1 of the present embodiment, the ECU 10 has a proficiency level determination unit 15 in addition to the communication unit 11 and the driving control unit 12. In addition, it is possible to communicate with various facilities 7 and the vehicle driving support server 60 by road-to-vehicle communication or communication via an Internet connection via the communication unit 11.

The proficiency level determination unit 15 of the ECU 10 has a function of determining the proficiency level (degree of driving skill) of the driver of the vehicle 2 based on the information obtained from the sensor 20. As a method for determining the proficiency level, a known technique including AI can be appropriately used. For example, the determination can be made based on the degree and number of times of sudden steering, sudden acceleration, sudden braking, and the like. You may consider the number of times of turning back when parking.

The information of the sensor 20 used for determining the proficiency level is transmitted to the vehicle driving support server 60 as a driving log via the communication unit 11. The vehicle driving support server 60 records and accumulates the driving log collected from each vehicle 2 as a driving log 62, and the difficulty analysis unit 61 implemented as software makes each road and each facility based on the driving log 62. The difficulty level of driving such as the parking lot of No. 7 is analyzed and recorded as the driving difficulty level 63. For parking lots, the difficulty level may be analyzed in detail for each parking space. Each vehicle 2 can access the vehicle driving support server 60 via the communication unit 11 and acquire information on the driving difficulty level 63 related to a desired road, a parking lot of a facility 7, or the like.

<Control by proficiency>
In the present embodiment, the vehicle 2 being manually driven is navigated by the car navigation system 40 by selecting a facility 7 suitable for stopping in according to the driver's proficiency level and the situation of the facility 7. For example, in addition to the driver's proficiency level, as the situation of facility 7, driving is performed in consideration of information on the difficulty level of driving on the road leading to the facility 7 and the difficulty level of parking / stopping the parking lot of the facility 7. Navigating to stop at facility 7, which is easy to park and stop. Information on the difficulty level of driving and parking includes, for example, the width of the road facing the parking lot of facility 7, which lane the parking lot is on the side of the vehicle 2 in the direction of travel, and parking in the parking lot. It includes static information such as the location of the space and dynamic information such as the traffic volume on the road near the parking lot and the congestion status of the parking lot.

As the static information, the information registered in advance in the car navigation system 40 may be used, or the information acquired from the driving difficulty level 63 of the vehicle driving support server 60 may be used. The dynamic information may be acquired, for example, via road equipment 3 or the like by road-to-vehicle communication, or may be acquired directly from the facility 7 by communication via an Internet connection.

As described above, the difficulty level analysis unit 61 of the vehicle driving support server 60 analyzes the difficulty level of driving such as the parking lot of each road or facility 7, and records it as the driving difficulty level 63. The difficulty level can be calculated based on a predetermined standard from static information such as the width of a road, the position of a parking lot / parking space, and the existence of obstacles. It is also possible to perform statistical analysis based on the driving log 62 collected from each vehicle 2 to determine the difficulty level. For example, it is difficult / easy to drive, difficult to park / stop / based on information on the deceleration status of the speed of each vehicle 2 on the target road, steering wheel operation, brake operation, turning operation when parking in the target parking lot, etc. Ease and the like can be judged. By recording the driver's proficiency level information in the driving log 62, the difficulty level may be determined by the correlation with the proficiency level.

<Acquisition and presentation of various information>
Further, in the present embodiment, the driver and passengers of the vehicle 2 (which may be in automatic driving or manual driving) can be informed of the surrounding traffic conditions via the car navigation system 40 or its display or the like. More detailed information can be referred to.

FIG. 11 is a diagram showing an outline of an example of a user interface that refers to the surrounding traffic conditions in the present embodiment. Here, the screen of the road map displayed on the display having the touch panel function of the car navigation system 40 is shown. In the upper figure, the situation where the road being displayed is congested is shown by dark shading. However, since the same shading is applied uniformly, it is possible to grasp only the presence or absence of traffic congestion, and it is not possible to grasp the difference and distribution of the degree of traffic congestion in the traffic jam section. Therefore, in order to enlarge and display this congested section, it is shown that the driver or the passenger made a pinch-out gesture by the touch panel function.

The middle figure shows a state in which the display is enlarged centering on the target position by the pinch-out gesture in the upper figure. Here, the road map is enlarged and the congestion situation is displayed in a more subdivided manner (shaded colors are separated). Then, in order to further enlarge the congested section, it is shown that the driver or the passenger has made a further pinch-out gesture.

The lower figure shows a state in which the display is further enlarged centering on the target position by the pinch-out gesture in the middle figure. Here, the road map is further enlarged, the traffic congestion status is displayed by shading, and the positions of individual other vehicles 2'are also displayed by icons or the like so that the positions can be grasped. The position of each other vehicle 2'is determined, for example, by notifying the traffic control system 50 and the vehicle driving support server 60 of the position information detected by these other vehicles 2'by the GPS sensor via road-to-vehicle communication. It can be grasped centrally. It may be something like analyzing and grasping image data of a satellite photograph or a photograph taken from the sky by a drone or the like.

Here, when the driver or the passenger makes a touch gesture on the touch panel for a specific other vehicle 2', for example, although not shown, the video data of the drive recorder 30 provided in the other vehicle 2'is used as a vehicle. It may be acquired by inter-vehicle communication or communication by internet connection and displayed. In addition, instead of directly designating the other vehicle, etc. 2', when the driver or passenger further makes a pinch-out gesture in the middle figure or the lower figure, the other vehicle, etc. closest to the target position, etc. Regarding 2', the image of the drive recorder 30 may be acquired and displayed in the same manner.

In this way, by making it possible to display the image of the drive recorder 30 of the other vehicle, etc. 2', the drive recorder 30 can be shared with the other vehicle, etc. 2', and the actual congestion situation and street view of the target position can be obtained. (Registered trademark) can be referred to. By the pinch-in gesture, the road map can be zoomed out contrary to the example of FIG.

As described above, according to the vehicle driving support system 1 according to the second embodiment of the present invention, useful information is provided to the driver and passengers of the vehicle 2 via the car navigation system 40 or its display or the like. Can be presented.

(Embodiment 3)
The vehicle driving support system according to the third embodiment of the present invention links the vehicle 2 (either during automatic driving or manual driving) and the drone to the driver or passenger of the vehicle 2. It provides useful functions.

<System configuration>
FIG. 12 is a diagram showing an outline of a configuration example of a vehicle driving support system according to a third embodiment of the present invention. Since the configuration is substantially the same as that shown in FIG. 1 of the first embodiment, the description will be mainly limited to the differences. In the vehicle driving support system 1 of the present embodiment, the vehicle 2 normally travels while flying with one or more various drones 8 in the vicinity.

The ECU 10 of the vehicle 2 has a drone control unit 16 in addition to the communication unit 11 and the operation control unit 12. The drone control unit 16 communicates with the drone 8 via the communication unit 11, and receives flight control and operation instructions of the drone 8 and information from the drone 8 (for example, video information taken by a camera mounted on the drone 8). Acquire, etc.

FIG. 13 is a diagram showing an outline of an example of a control mode of the drone 8 in the present embodiment. As shown in the example of the vehicle 2 on the left side (front), the drone 8 usually communicates with a specific vehicle 2 (usually the vehicle 2 on which the driver or passenger who owns the drone 8 rides). Under control. In this case, the vehicle 2 receives instructions from the driver and passengers, and the drone control unit 16 controls the drone 8 to perform various processes. For example, the drone 8 is moved to a remote location, and video data obtained by capturing a traffic jam situation, a congestion situation, or the like is acquired via the communication unit 11.

On the other hand, as shown in the vehicle 2 on the right side (rear), the drone 8 owned by another person is not limited to the drone 8 owned by the driver or the passenger, such as sharing the drone 8 among a plurality of vehicles 2. It may be possible to control directly or indirectly. In this case, it may be the case that the drone 8 is not owned by itself. Further, the drone 8 is not limited to the one owned by the driver or passenger of any vehicle 2, and may be, for example, a drone 8 provided for public use by a local government or the like. When sharing the drone 8, for example, the vehicle 2 having the control right of the drone 8 is determined based on a predetermined procedure or rule by vehicle-to-vehicle communication between the vehicles 2 to be shared.

FIG. 14 is a diagram showing an outline of an example of delivery of an article by the drone 8 in the present embodiment. Here, an example is shown in which the vehicle 2 receives the delivery of goods by the drone 8. For example, in a traffic jam, the driver or passenger of the vehicle 2 may use the communication via the Internet connection via the communication unit 11 or the mobile communication by the mobile terminal such as a smartphone owned in advance to the store in front of the store ( For example, an order and payment are made via a network to a store (a store that can be purchased without entering the store, such as a drive-through).

Then, as shown in the figure, the accompanying drone 8 is instructed to pick up the product from the store in front and return to the vehicle 2, and the product is acquired from the returned drone 8. As a result, for example, it is possible to purchase and deliver a product while in a congested convoy. By delivering the battery (or converting the drone 8 itself into a battery), it is possible to realize a mechanism for supplying power while the vehicle 2 (for example, an electric vehicle or a so-called hybrid vehicle) is moving.

FIG. 15 is a diagram showing an outline of another example of delivery of goods by the drone 8 in the present embodiment. Here, an example is shown in which a vehicle 2 such as a delivery truck of a courier company delivers an article by a drone 8. As shown in the figure, for example, one or more vehicles 2 such as a courier who deliver packages by going around a plurality of delivery destinations in order do not have to go directly to the delivery destination's house or condominium, but while the delivery route is moving. The drone 8 that stores the cargo is flown to each delivery destination so that the cargo is delivered in sequence and then returned to the vehicle 2. Then, a series of processes of storing another package and flying it to each delivery destination again is repeated. In this way, by making it possible to move the delivery route of the vehicle 2 and deliver the package to each delivery destination by the drone 8 in parallel asynchronously (delivery of the "last mile"), the delivery efficiency can be improved. Greatly improve.

When delivering luggage by the drone 8, as in the above example, the drone 8 does not fly along with the running of the vehicle 2, but the drone 8 containing the delivered luggage is loaded by the vehicle 2 such as a truck. It may be stored in a place such as a vehicle, traveled, and taken off at an appropriate place toward the delivery destination. In this case, the drone 8 that has delivered the package and returned is collected, for example, on a loading platform or the like.

Optimizing the delivery plan, such as what kind of delivery route the vehicle 2 takes, where the drone 8 should be taken off, and where it should be collected, is a method known by, for example, the drone control unit 16 of the ECU 10. Etc. can be used as appropriate. When it is necessary to stop the vehicle 2 for the arrival and departure of the drone 8, the optimization should be performed in consideration of the place where the vehicle 2 can be parked and stopped. When it is detected that the drone 8 that has taken off and headed for delivery cannot return to the vehicle 2, for example, by contacting the collection person in charge of the delivery company, the collection is performed asynchronously with the delivery of other packages. ..

In houses, condominiums, etc. that receive parcel delivery, a drone port or drone box for the drone 8 to place the parcel shall be installed in the garden, veranda, or the like. For example, when constructing a condominium or other condominium, the load of delivering luggage to each house will be high for each house with a predetermined number of floors or more, so the above-mentioned drone port and drone box will be incorporated in advance. May constitute one or more balconies.

As described above, according to the vehicle driving support system 1 according to the third embodiment of the present invention, the vehicle 2 and the drone 8 are linked to provide a useful function for the driver and passengers of the vehicle 2. Can be provided.
