  Hereinafter, an example of an embodiment of the present invention will be described based on the drawings. FIG. 1 is a diagram showing an example of a functional block configuration of the recommended operation output system 1. The recommended driving output system 1 includes a recommended driving output device 10 and a driving support device 20. The recommended operation output device 10 is an on-vehicle device that outputs information to a user. The recommended operation output device 10 is an information processing device such as a navigation device, an electronic control unit (ECU), a personal computer (PC), or a smartphone. The recommended driving output device 10 and the driving support device 20 are mounted on the same vehicle and connected communicably. The communication method is not limited.

  Hereinafter, a vehicle equipped with the recommended driving output device 10 and the driving support device 20 will be described as a host vehicle, and vehicles other than the host vehicle traveling around the host vehicle will be described as other vehicles.

  The driving support device 20 is, for example, a device having a function of an advanced driving support system (ADAS) or a function of an automatic driving control system. The driving support device 20 may be an information processing device such as an ECU.

  The recommended operation output device 10 is communicably connected to the head-up display 301, the meter display 302, the seat vibration function 303, and the speaker 304. The head-up display 301 is a display disposed on the upper portion of the instrument panel below the windshield in the car. The head-up display 301 may be, for example, a display that exerts a function by projecting an image on a combiner provided in front of a windshield, or exhibits its function by projecting an image directly on the windshield. It may be

  The meter display 302 is a display such as an LCD (Liquid Crystal Display) installed on an instrument panel. The seat vibration function 303 is built in the driver's seat, and vibrates the driver's seat using, for example, a vibrator. The seat vibration function 303 has, for example, a plurality of vibrators installed at different positions on the driver's seat, and each vibrator can be controlled independently. Thereby, each vibrator can be vibrated in a predetermined pattern according to the information notified to the driver. The speaker 304 is a device that outputs sound.

  The driving support device 20 is communicably connected to the external camera 305. The external camera 305 is an imaging device using an image sensor such as a CCD (Charge Coupled Device), which captures the situation outside the vehicle and outputs a still image or a moving image. The external camera 305 is one or more cameras, and can capture the surroundings such as the front, the rear, and the side of the host vehicle.

  The driving support device 20 may be connected to a sensor that can specify the distance to an object outside the vehicle, a radar, or LIDAR (Light Detection and Ranging), in addition to the camera 305 for the outside of the vehicle.

  The recommended operation output device 10 includes a control unit 110, a communication unit 120, and a storage unit 130. The control unit 110 controls the entire recommended operation output device 10 in an integrated manner. The communication unit 120 transmits and receives information with a device such as the driving support device 20 connected to the recommended operation output device 10. The storage unit 130 stores information necessary for processing by the control unit 110.

  The control unit 110 includes a vehicle condition acquisition unit 111, a warning reception unit 112, a driver condition determination unit 113, a target vehicle condition determination unit 114, an output processing unit 115, and an input processing unit 116. The vehicle status acquisition unit 111 acquires information indicating the status of the host vehicle and the status of the other vehicle. More specifically, the vehicle status acquisition unit 111 specifies the current position of the vehicle using a GPS (Global Positioning System) receiving device described later. Also, using the current position and the map information stored in the storage unit 130, the vehicle status acquisition unit 111 uses the travel position of the host vehicle (for example, the lane in which the host vehicle is traveling among the lanes of the road) Identify Note that the vehicle status acquisition unit 111 may specify the current position of the host vehicle using information received from an external camera or radar described later.

  In addition, the vehicle status acquisition unit 111 acquires information indicating the status of another vehicle transmitted from the driving support device 20. The information indicating the condition of the other vehicle is, for example, a photographed image of the other vehicle. The vehicle status acquisition unit 111 specifies the traveling position of another vehicle using the information and the map information. The vehicle status acquisition unit 111 may specify the traveling position of another vehicle using information received from an external camera or radar described later.

  The warning reception unit 112 receives a warning according to the vehicle condition from the driving support device 20. The warning includes information for specifying a target vehicle which is another vehicle to be a target of the generated warning. The information for specifying the target vehicle is, for example, a number described on a vehicle number sign (so-called license plate), a position of the target vehicle in a photographed image, a color of a car, or a headlight when viewed from the other vehicle front Position etc.

  The driver's situation determination unit 113 determines whether or not the driver of the other vehicle can not pay attention to the traveling direction (hereinafter, described as the “needed avoidance state”). For example, when the driver of the other vehicle is in the avoidance state such as the posture of the driver being bumped, it is desirable that the driver of the own vehicle immediately avoid the other vehicle. Therefore, the driver's situation determination unit 113 determines, for example, whether or not the driver is in the avoidance state by analyzing images of other vehicles.

  The driver condition determination unit 113 analyzes the image to identify the driver's condition of the other vehicle, and determines whether the driver of the other vehicle is in the avoidance state. For example, the driver's situation determination unit 113 specifies the driver's state by using the driver's posture such as the driver being bumped. Known techniques can be used to analyze the image.

  The information used to determine the avoidance required state is not limited to the driver's posture. For example, when the driver's face does not face the traveling direction, the driver situation determination unit 113 may determine that the driver is in the avoidance state.

  In addition, the driver's situation determination unit 113 identifies the driver's posture of the other vehicle by using, for example, an ultrasonic sensor or an infrared sensor instead of the image analysis, and determines whether or not the avoidance state is necessary. May be For example, the driver's situation determination unit 113 detects the line-of-sight direction of the driver of the other vehicle, and determines that it is a necessary avoidance state when the line-of-sight direction continues for a fixed time and faces a direction other than the host vehicle. It is also good.

  The target vehicle condition determination unit 114 specifies another vehicle to be a target of the warning. Specifically, the target vehicle condition determination unit 114 specifies a target vehicle to be a target of a warning among other vehicles, using the information received at the time of receiving the warning.

  The output processing unit 115 outputs information to an output device such as the head-up display 301, the meter display 302, the sheet vibration function 303, or the speaker 304. For example, the output processing unit 115 outputs the recommended driving instruction information when the warning reception unit 112 receives the warning and the driver of the other vehicle is in the avoidance state. Further, the output processing unit 115 outputs the caution information when the warning reception unit 112 receives the warning and the driver is not in the avoidance state. Attention information and recommended driving instruction information are different.

  In addition to displaying information on the head-up display 301 or the meter display 302, the output processing unit 115 may vibrate the driver's seat by the seat vibration function 303 in a predetermined pattern. For example, when outputting the recommended driving instruction information to avoid in the right lane, the output processing unit 115 vibrates the seat vibration function 303 so that the seat surface vibrates from left to right. Further, the output processing unit 115 may cause the speaker 304 to output a voice uttering the recommended driving instruction information or the caution information.

  The input processing unit 116 acquires information input via an input device such as a touch panel.

  The storage unit 130 stores the recommended driving information 131 and the map information 132. The recommended driving information 131 is information in which a vehicle condition is associated with recommended driving instruction information indicating a recommended driving instruction when the vehicle condition occurs. The map information 132 is information indicating a map, and by using information indicating the current location of the vehicle, it is specified whether the lane in which the vehicle is traveling or the road on which the vehicle is traveling are straight or curved. be able to.

  The driving support device 20 includes a control unit 210 and a communication unit 220. The control unit 210 centrally controls the entire driving support device 20. The communication unit 220 transmits and receives information to and from other devices connected to the driving support device 20.

  The control unit 210 includes a situation detection unit 211 and a warning notification unit 212. The situation detection unit 211 detects the situation of the own vehicle and the other vehicle by referring to the image captured using the external camera 305. In addition, the situation detection unit 211 periodically transmits the captured image to the recommended operation output device 10.

  Further, the situation detection unit 211 detects an inter-vehicle distance and a relative speed between another vehicle and the host vehicle. The situation detection unit 211 detects the situation of another vehicle, for example, by analyzing a plurality of images. Known techniques can be used to analyze the image. For example, the situation detection unit 211 extracts the other vehicle traveling toward the host vehicle by comparing the position of the headlight in front of the vehicle included in the plurality of images. The situation detection unit 211 compares a plurality of images, and calculates the inter-vehicle distance between the extracted other vehicle and the host vehicle, and the traveling speed of the other vehicle. The situation detection unit 211 may detect the situation of another vehicle using a sensor such as an infrared ray.

  The warning notification unit 212 notifies the recommended operation output device 10 of a warning according to the condition of the other vehicle. More specifically, the warning notification unit 212 uses the inter-vehicle distance and the relative speed between the host vehicle and the other vehicle to calculate the time required for the contact of the vehicle. The warning notification unit 212 compares the time with a threshold stored in advance, and notifies the recommended operation output device 10 of a warning when the time is less than the threshold. The warning includes information for identifying the target vehicle, which is obtained by analysis of the image.

  FIG. 2 is a diagram showing an example of the recommended driving information 131. As shown in FIG. The recommended driving information 131 includes identification information 131a, a host vehicle condition 131b, another vehicle condition 131c, and recommended driving instruction information 131d. The identification information 131a is information for identifying each record of the recommended driving information 131. The host vehicle condition 131 b is information indicating the position of the host vehicle. The host vehicle condition 131 b is, for example, a road type indicating the type of “general road” or “high speed road”, a general road type indicating “straight line” or “curved”, “left”, “center” "Or" right "includes the own vehicle position indicating the traveling lane of the own vehicle.

  The other vehicle situation 131 c includes information indicating the position of the other vehicle. For example, the other vehicle status 131c may be "left _ front", "center _ front", "right _ front", "left _ back", "center _ back", "right _ back", "opposite lane", etc. It is information. The recommended driving instruction information 131 d is a character string indicating the recommended driving.

  For example, in the recommended driving information 131 shown in FIG. 2, in the record where the identification information 131a is "01", the road type is "general road" and the general road type is "straight line" in the host vehicle condition 131b. , Own vehicle position is "left". Further, the other vehicle status 131c of the record is “left_rear”, and the recommended driving instruction information 131d is “right lane movement”.

  This is because when the host vehicle travels in the left lane on a straight general road and another vehicle travels behind the left lane, a warning is output and the driver is in the avoidance state, the right Indicates that it is desirable to drive to the lane. That is, the output processing unit 115 outputs recommended driving instruction information for moving to the right lane.

  In addition, the information which shows the output destination of the recommended driving instruction information 131d is associated with the recommended driving information 131 in advance. Further, the recommended driving instruction information 131 d includes voice information for uttering the recommended driving instruction, and information for specifying a vibration pattern for vibrating the driver's seat, instead of or in addition to the character string indicating the recommended driving. It may be done.

  In the other vehicle status 131 c of the recommended driving information 131 shown in FIG. 2, “1” indicates the target vehicle, and “2” indicates the other vehicle other than the target vehicle.

  That is, for example, among the records of the recommended driving information 131 in FIG. 2, in the other vehicle status 131 c whose identification information 131 a is “12”, “left_front”, “center_front”, and “center_ “2” is associated with “after”, and “1” is associated with “left_after”. This is because there are other vehicles that are not the target vehicle in the left lane ahead of the vehicle, the center lane forward of the vehicle on the right, and the center lane behind the vehicle on the right of the vehicle behind the vehicle. It shows a situation where the target vehicle is behind the left lane, which is the rear.

  FIG. 5 is a flowchart showing an example of the recommended operation output process. The process of this flowchart is, for example, periodically executed in the recommended operation output device 10.

  First, the vehicle status acquisition unit 111 acquires the host vehicle position (step S11). Specifically, the vehicle status acquisition unit 111 specifies the current position of the host vehicle using the positioning signal reception device 174, and specifies the travel position of the host vehicle with reference to the map information 132.

  Next, the vehicle status acquisition unit 111 acquires the position of the other vehicle (step S12). Specifically, the vehicle status acquisition unit 111 acquires an image periodically transmitted from the driving support device 20. The image shows the situation around the vehicle. The vehicle status acquisition unit 111 identifies the current position of the other vehicle using the position and shooting direction of the external camera 305 that has captured the image, the size of the other vehicle displayed in the image, and the current position of the vehicle. Do. The vehicle status acquisition unit 111 collates the current position of the other vehicle with the map information 132 to specify the traveling position of the other vehicle. In addition, the image transmitted from the driving assistance device 20 may be a moving image.

  Next, the vehicle status acquisition unit 111 determines whether there is a record corresponding to the recommended driving information 131 (step S13). Specifically, the vehicle status acquisition unit 111 refers to the recommended driving information 131 and determines whether or not there is a record including the own vehicle position identified in step S11 and the position of the other vehicle identified in step S12. Do.

  If the vehicle status acquisition unit 111 determines that there is no record corresponding to the recommended driving information 131 (in the case of “NO” in step S13), the vehicle status acquisition unit 111 returns the process to step S11.

  If the vehicle status acquisition unit 111 determines that there is a record corresponding to the recommended driving information 131 (in the case of “YES” in step S13), the warning reception unit 112 determines within a predetermined period before and after the determination (for example, 2 It is determined whether or not a warning has been received from the driving support device 20 within 2 seconds (step S14). The warning notification unit 212 of the driving support device 20 calculates the time required for the contact of the vehicle, and outputs a warning to the recommended driving output device 10 when the calculated time is less than the threshold. If the vehicle status acquisition unit 111 receives the warning transmitted from the warning notification unit 212, the process proceeds to step S15.

  When the warning reception unit 112 determines that the warning has not been received within the predetermined period (in the case of “NO” in step S14), the warning reception unit 112 returns the process to step S11.

  If the warning reception unit 112 determines that a warning has been received (in the case of “YES” in step S14), the target vehicle status determination unit 114 specifies an image of the target vehicle (step S15). Specifically, the target vehicle condition determination unit 114 identifies the target vehicle included in the warning and the image of the other vehicle received from the driving assistance device 20 simultaneously with the warning reception or within a predetermined time from the warning reception. And identify the target vehicle displayed in the image.

  When there are a plurality of other vehicles, the vehicle status acquisition unit 111 extracts the position of the target vehicle in the other vehicle status 131c in the record of the recommended driving information 131 determined to be applicable in step S13. The vehicle status acquisition unit 111 specifies the position of the target vehicle using the information included in the warning, determines whether or not the position matches the position in the record, and determines that the process matches step S16. Advance. If they do not match, the vehicle status acquisition unit 111 returns the process to step S11.

  Next, the target vehicle condition determination unit 114 determines whether the target vehicle is emitting a blinker (step S16). The target vehicle condition determination unit 114 analyzes the image of the target vehicle identified in step S15, and determines whether or not the winker is taken out.

  When the target vehicle condition determination unit 114 determines that the target vehicle does not have a blinker (in the case of “NO” in step S16), the driver condition determination unit 113 determines whether the driver's condition is in the avoidance state. It is determined whether or not it is (step S17). Specifically, the driver's situation determination unit 113 analyzes the image of the target vehicle identified in step S15, and determines whether or not the driver's posture is in a pre-set avoidance state.

  When the driver's situation determination unit 113 determines that the driver's situation is in the avoidance state (in the case of “NO” in step S17), the output processing unit 115 generates output information including the recommended driving instruction information. (Step S18). Specifically, the output processing unit 115 identifies the recommended driving instruction information 131d included in the record determined as the corresponding record in step S13. The output processing unit 115 generates output information of a display screen including the specified recommended driving instruction information 131 d.

  Next, the output processing unit 115 outputs the output information (step S19). Specifically, the output processing unit 115 causes the output device such as the head-up display 301 to output the output information generated in step S18. In addition, when outputting audio | voice information and a vibration pattern as recommendation driving instruction information, the output process part 115 is with respect to the speaker 304 and the sheet vibration function 303 using the audio | voice information and vibration pattern corresponding to the record of the recommended driving information 131. Output recommended operation instruction information. After that, the control unit 110 ends the processing of this flowchart.

  When the target vehicle status determination unit 114 determines that the target vehicle is emitting a blinker (in the case of “YES” in step S16), or the driver status determination unit 113 does not require the driver to be in the avoidance state. If it is determined that (step S17 is "NO"), the output processing unit 115 generates output information including attention information (step S20). Specifically, the output processing unit 115 generates display information of the display screen using the caution information included in the not-shown area of the storage unit 130.

  Next, the output processing unit 115 outputs the output information (step S21). Specifically, the output processing unit 115 causes the output device to output the output information generated in step S20. Similar to the process shown in step S19, in the case of outputting voice information or a vibration pattern as the caution information, the output processing unit 115 uses the voice information or the vibration pattern included in the not-shown area of the storage unit 130 to output the speaker 304 or the like. Attention information is output to the sheet vibration function 303. After that, the control unit 110 ends the processing of this flowchart.

  In the present embodiment, the vehicle status acquisition unit 111 acquires the status such as the relative speed and the position of the other vehicle by analyzing the image. However, the means for acquiring the situation of the other vehicle is not limited to the analysis of the image. For example, the relative speed or position of another vehicle may be specified using information from a sensor such as an infrared sensor or radar. Similarly, the condition detection unit 211 of the driving support device 20 may detect the condition of another vehicle using information from a sensor or a radar.

  Further, in the present embodiment, the driving support device 20 transmits the information specifying the target vehicle to the recommended driving output device 10 when outputting the caution information, but the processing for specifying the target vehicle is the recommended driving output Device 10 may do this. In that case, when the warning is received from the driving support device 20, the target vehicle condition determination unit 114 of the recommended driving output device 10 transmits the camera from the driving support device 20 or the camera for the external vehicle connected to the recommended driving output device 10. The image acquired from 305 can be analyzed to identify the position and relative velocity of the target vehicle.

  According to this embodiment, when the driver of another vehicle is in the avoidance state, recommended driving instruction information different from the normal caution information can be output. Thus, the driver of the host vehicle can recognize the recommended driving instruction information for avoiding the other vehicle driven by the driver who is in the avoidance state.

  FIG. 6 is a schematic diagram (part 1) for explaining the situation of the vehicle. Vehicle A, which is the own vehicle, is traveling in front of vehicle B, which is another vehicle. Vehicles A and B are traveling in the left lane of a straight road. In this case, the warning notification unit 212 of the driving support device 20 determines whether the time required for the contact between the own vehicle and the other vehicle is less than the threshold, and if it is less than the threshold, the recommended driving output device 10 Send a warning to

  When the subject vehicle travels in the left lane of a straight road and the target vehicle travels behind the left lane, among the recommended driving information 131 shown in FIG. 2, the record in which the identification information 131a is "01" is included.
