  “Nearby vehicle” is a vehicle that exists in the vicinity of the host vehicle, for example, a circular area (hereinafter referred to as “nearby”) with a predetermined radius (for example, a distance that enables inter-vehicle communication) centered on the host vehicle. It is a vehicle existing in the range.

  The inter-vehicle communication device 2 is a device for controlling two-way communication between the host vehicle and another vehicle. For example, the inter-vehicle communication device 2 uses a frequency in the VHF / UHF band and is in the vicinity of several kilometers (the position of the host vehicle). The vehicle information request signal is transmitted periodically (for example, every second), and the vehicle information signal returned by the other vehicle in response to the information request signal is received. The inter-vehicle communication device 2 is an example of “neighboring vehicle information collecting means” in the claims.

  The “vehicle information request signal” is a signal for prompting the transmission of the vehicle information signal. In addition, the “vehicle information signal” is a signal including information regarding a transmission source vehicle, and includes, for example, an identification number of the transmission source vehicle. The vehicle information signal includes a vehicle position (latitude, longitude, altitude) output by a GPS (Global Positioning System) mounted on the transmission source vehicle, a vehicle speed output by a speed sensor mounted on the transmission source vehicle, and transmission. An identification number or the like of the preceding vehicle (the vehicle that transmitted the vehicle information request signal) may be included. This is because only the vehicle that has transmitted the vehicle information request signal can receive the vehicle information signal.

  In addition, the inter-vehicle communication device 2 may be a device having only a reception function for receiving a vehicle information signal periodically transmitted by another vehicle (for example, every second).

  The wide area wireless communication apparatus 3 is an apparatus for controlling wide area wireless communication, and controls wireless communication using, for example, a mobile phone frequency or a PHS (Personal Handy-phone System) frequency. The wide area wireless communication device 3 is an example of “communication means” in the claims.

  The storage device 4 is a device for storing various types of information. For example, a nearby vehicle database 40 (hereinafter referred to as “neighbored vehicle DB 40”) that systematically stores information related to nearby vehicles, information related to registered vehicles. Registered system database 41 (hereinafter referred to as “registered vehicle DB 41”) and a travel record database 42 (hereinafter referred to as “travel record DB 42”) that systematically stores the travel records of the host vehicle. And so on.

  The “registered vehicle” is a vehicle group in which information for identifying the vehicle by a passenger of the host vehicle is registered in advance, and corresponds to, for example, a vehicle of an acquaintance or a friend or a vehicle of a company that works.

  FIG. 2 is a diagram illustrating a configuration example of the nearby vehicle DB 40. The nearby vehicle DB 40 stores a vehicle identification number field for storing a vehicle identification number for specifying a vehicle, and a time when the vehicle is first recognized as a nearby vehicle. “Recognition time” column, “Recognition position” column for storing the position recognized as a nearby vehicle for the first time, “Recognition time” column for storing the time recognized as a nearby vehicle, and “Tracking degree with respect to own vehicle” It includes a “following degree” column, a “registered vehicle” column that stores whether the vehicle is a registered vehicle, and a “suspicious vehicle” column that stores whether the vehicle is a suspicious vehicle.

  The “following degree” is expressed, for example, by the degree of coincidence of the transition of the traveling speed of each neighboring vehicle with respect to the transition of the traveling speed of the own vehicle. Calculated as a percentage of the total recognition time.

  Further, the “suspicious vehicle” is a vehicle that performs a nuisance act or a vehicle that performs a suspicious act that seems to be tailing or chasing.

  FIG. 3 is a diagram illustrating a configuration example of the travel record DB 42. The travel record DB 42 includes various events performed by the host vehicle (turning left and right, parking, stopping from the recommended route presented by the navigation device, and the like). An “event” column for storing the type of event, and an “occurrence time” column for storing times when various events occur. The travel record DB 42 is used when the below-described suspicious vehicle determination unit 13 determines whether a suspicious vehicle exists.

  The nuisance detecting device 5 is a device for detecting nuisance by a vehicle traveling around the host vehicle, and includes an imaging element such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor). A camera is used to detect nuisances such as passing by the headlight of a following vehicle, meandering driving of a vehicle traveling around, and width-shifting.

  Further, the nuisance detection device 5 may detect frequent use of sudden braking by the preceding vehicle and a rolling operation by the following vehicle using a millimeter wave radar.

  The display device 6 is a device for displaying various kinds of information to passengers in the passenger compartment, and includes, for example, a liquid crystal display attached to the navigation device. Moreover, the audio | voice output apparatus 7 is an apparatus for outputting various audio | voice information with respect to the passenger in a vehicle interior, for example, there exists a vehicle-mounted speaker.

  Next, various units included in the control device 1 will be described.

  The nearby vehicle monitoring unit 10 is a unit for monitoring a vehicle that travels in the vicinity of the host vehicle, and updates the nearby vehicle DB 40 based on, for example, information on the nearby vehicle acquired through the inter-vehicle communication device 2.

  For example, when the inter-vehicle communication device 2 receives a vehicle information signal from another vehicle for the first time, the nearby vehicle monitoring means 10 registers the vehicle identification number of the vehicle in the “vehicle identification number” field, Record in the “Time” column.

  Further, after recognizing the vehicle, the nearby vehicle monitoring means 10 periodically monitors the vehicle information request signal for a response from the vehicle, and updates the value in the “recognition time” column as long as a response is obtained. Like that.

  In addition, if the response to the vehicle information request signal from the nearby vehicle that has been recognized once is no longer obtained, the nearby vehicle monitoring means 10 is in the vicinity when a predetermined time (for example, 30 minutes) elapses without obtaining a response. The record for the vehicle is deleted from the nearby vehicle DB 40.

  This is to allow the monitoring of a nearby vehicle that has returned to the nearby range to be resumed without resetting the recognition time of the nearby vehicle that has deviated from the nearby range for a short time. This is in order not to continue monitoring the vehicle without deviating or returning to the vicinity.

  The nearby vehicle information output means 11 is a means for outputting information related to the nearby vehicle to the passenger of the own vehicle. For example, the nearby vehicle information whose recognition time has become a predetermined time T1 (for example, 30 minutes) or more ( Hereinafter, “specific nearby vehicle” is displayed on the display device 6 so that it can be distinguished from other nearby vehicles.

  The nearby vehicle information output unit 11 may output a voice message about the specific nearby vehicle from the voice output device 7.

  FIG. 4 is a display example of information related to a nearby vehicle by the nearby vehicle information output means 11, and displays the positional relationship between the nearby vehicle and the host vehicle.

  In FIG. 4A, the vehicle V3 shown in gray is the own vehicle, and the vehicles V2, V4, V5, and V7 to V9 shown in broken lines are neighboring vehicles having a recognition time of less than 30 minutes.

  FIG. 4B shows a state in which the display method of the nearby vehicle is changed according to the recognition time, and the specific nearby vehicle having the recognition time of 30 minutes or more and less than 60 minutes is represented by a thin solid line rectangular icon. A specific nearby vehicle having a duration of 60 minutes or more and less than 90 minutes is represented by a thick solid line rectangular icon, and a specific nearby vehicle having a recognition time of 90 minutes or longer is represented by a thicker solid line rectangular icon.

  In FIG. 4A, a vehicle V6 is a specific nearby vehicle having a recognition time of 30 minutes to less than 60 minutes, a vehicle V10 is a specific nearby vehicle having a recognition time of 60 minutes to less than 90 minutes, and the vehicle V1 is A specific nearby vehicle with a recognition time of 90 minutes or more.

  As described above, the nearby vehicle information output unit 11 changes the display mode such as the line type, the painting method (shaded), and the color of the icon image representing the nearby vehicle according to the recognition time, the degree of tracking, and the like. The degree of tracking may be displayed as a numerical value.

  FIG. 5 is another display example of information related to a nearby vehicle by the nearby vehicle information output means 11, and shows how the degree of painting increases as the follow-up degree increases.

  With reference to FIG. 1 again, description of the various means which the control apparatus 1 has is continued.

  The registered vehicle determination means 12 is a means for determining whether or not the specific nearby vehicle whose recognition time is equal to or longer than the predetermined time T2 corresponds to the registered vehicle, for example, referring to the registered vehicle DB 41 The vehicle identification number of the registered vehicle registered in the registered vehicle DB 41 is compared with the vehicle identification number of the specific nearby vehicle, and when the vehicle identification number can be verified, it is determined that the specific nearby vehicle is a registered vehicle. To do. The predetermined time T2 may be the same as the predetermined time T1.

  When the registered vehicle determination unit 12 determines that the specific nearby vehicle is a registered vehicle, the registered vehicle determination unit 12 notifies the nearby vehicle information output unit 11 to that effect, and the nearby vehicle information output unit 11 The registered vehicle is displayed on the display device 6 so that the vehicle can be identified.

  FIG. 6 is another display example of information related to a nearby vehicle by the nearby vehicle information output means 11, and shows that the vehicles V11 and V12 painted with diagonal lines are registered vehicles.

  The suspicious vehicle determination means 13 is a means for determining whether or not the specific nearby vehicle whose recognition time is equal to or longer than the predetermined time T3 corresponds to the suspicious vehicle. For example, the specific nearby vehicle stored in the nearby vehicle DB 40 The presence / absence of a suspicious vehicle is determined based on the following record and the travel record such as the number of left / right turns, parking / stopping times, or the number of departures from the recommended route over the past predetermined time T3 stored in the travel record DB 42. judge.

  The predetermined time T3 used for determination by the suspicious vehicle determination means 13 may be different from the predetermined time T2 used for determination by the registered vehicle determination means 12, and preferably the predetermined time T2 is the predetermined time T3. Less than. This is to notify the existence of the registered vehicle at an early stage.

  The suspicious vehicle determination means 13 is, for example, a case where there is a deviation from a recommended route by the own vehicle in the past 30 minutes, and there is a specific nearby vehicle whose follow-up degree is a predetermined value (for example, 90%) or more. When it does, it determines with the specific vicinity vehicle being a suspicious vehicle. This is because it is unnatural that the degree of follow-up is high even though the host vehicle is traveling specially so that it deviates from the recommended route, and it can be estimated that the specific nearby vehicle is tracking the host vehicle. Because.

  Further, the suspicious vehicle determination means 13 detects that the nuisance detecting device 5 detects an nuisance caused by the specific nearby vehicle, or the specific nearby vehicle is a dangerous vehicle (for example, dangerous driving in the past etc.) via the wide area wireless communication device 3. The vehicle is registered in the black list of the police or the like), the specific vehicle may be determined to be a suspicious vehicle.

  If the suspicious vehicle determination means 13 determines that the host vehicle is traveling in a traffic jam section based on the VICS information or the like, the suspicious vehicle determination means 13 may exclude the time between the recognition times, or The predetermined time T3 and the following degree for determining whether or not the specific nearby vehicle is a suspicious vehicle may be further increased (meaning that the determination condition is made stricter).

  This is to prevent a nearby vehicle that is unintentionally recognized as a specific nearby vehicle due to traffic jams or the like from being easily determined to be a suspicious vehicle.

  FIG. 7 is another display example of information related to the nearby vehicle by the nearby vehicle information output means 11, and shows that the vehicle V13 painted in black is a suspicious vehicle.

  The communication target setting unit 14 is a unit for supporting communication between the host vehicle and an external communication partner. For example, when the nearby vehicle monitoring device 100 recognizes a specific nearby vehicle, the communication target setting unit 14 A passenger of the own vehicle can easily start communication with the own vehicle via the wide area wireless communication device 3. In addition, the passenger of the own vehicle does not necessarily need to start communication, and the communication object setting means 14 is for supporting the start of communication in principle. However, it does not exclude that the communication target setting unit 14 automatically starts communication between the own vehicle and the specific nearby vehicle.

  For example, as shown in FIG. 8, the communication target setting unit 14 is already connected via the wide area wireless communication device 3 when the registered vehicles V11 and V12 are displayed on the display device 6 by the nearby vehicle information output unit 11. Buttons SW1 to SW3 are displayed so that communication can be started between the registered vehicles V11 and V12 and the host vehicle V3.

  The button SW1 is a button for starting communication between the registered vehicle V11 and the host vehicle V3, and the button SW2 is used for starting communication between the registered vehicle V12 and the host vehicle V3. The button SW3 is a button for starting communication between other points between the registered vehicles V11 and V12 and the host vehicle V3.

  The passenger of the host vehicle V3 presses any of the buttons SW1 to SW3 (in this case, the display device 6 includes a touch panel) to start communication with the corresponding registered vehicle and hands. Free conversation can be started, or the destination setting in both navigation devices can be adjusted.

  The communication between the host vehicle V3 and the registered vehicles V11 and V12 may be performed via the inter-vehicle communication device 2.

  Further, the communication target setting unit 14 can easily start communication between the registered vehicle and the host vehicle when the registered vehicle determination unit 12 determines that the specific nearby vehicle is a registered vehicle. However, when the registered vehicle deviates from the vicinity range, communication between the registered vehicle and the host vehicle may be started. This is because it is presumed that the passenger of the own vehicle wants to start communication with the registered vehicle.

  FIG. 9 is a flowchart showing a flow of processing in which the communication target setting unit 14 sets a registered vehicle deviating from the vicinity range as a communication partner.

  First, the nearby vehicle monitoring means 10 determines whether or not the specific nearby vehicle has deviated from the nearby range based on information on the nearby vehicle acquired via the inter-vehicle communication device 2 (step S1).

  When the specific vicinity vehicle remains in the vicinity range (NO in step S1), the communication target setting unit 14 ends the process without setting the specific vicinity vehicle as the communication partner. This is because the necessity of starting communication is low.

  On the other hand, when the specific nearby vehicle deviates from the vicinity range (YES in step S1), the communication target setting unit 14 causes the registered vehicle determination unit 12 to determine whether or not the specific nearby vehicle is a registered vehicle ( Step S2).

  When it is determined that the specific nearby vehicle is not a registered vehicle (NO in step S2), the communication target setting unit 14 ends the process without setting the specific nearby vehicle as a communication partner. This is because even if a vehicle that is not a registered vehicle deviates from the vicinity range, there is no relationship for the passenger of the host vehicle, and the necessity of starting communication is low.

  On the other hand, when it is determined that the specific nearby vehicle is a registered vehicle (YES in step S2), the communication target setting unit 14 notifies that the registered vehicle has deviated from the nearby range via the audio output device 7. A voice message is output (step S3), and a button for starting communication between the host vehicle and the registered vehicle is displayed on the display device 6 (step S4).

  In this way, the communication target setting unit 14 can easily and quickly start communication with the passenger of the registered vehicle in which the passenger of the own vehicle has deviated from the vicinity range.

  Further, the communication target setting unit 14 can easily start communication between the own vehicle and a predetermined facility such as the police when the suspicious vehicle determination unit 13 determines that the specific nearby vehicle is a suspicious vehicle. You may be able to do it.

  FIG. 10 is a flowchart showing a flow of processing in which the communication target setting unit 14 sets the police as a communication partner.

  First, the nearby vehicle monitoring unit 10 determines whether or not the specific nearby vehicle is a suspicious vehicle by the suspicious vehicle determination unit 13 (step S11).

  When it is determined that the specific nearby vehicle is not a suspicious vehicle (NO in step S1), the communication target setting unit 14 ends the process without setting the police as a target of voice communication. This is because there is no need to start voice communication.

  On the other hand, when it is determined that the specific nearby vehicle is a suspicious vehicle (YES in step S11), the communication target setting unit 14 determines whether or not the suspicious vehicle is a registered vehicle by the registered vehicle determination unit 12. (Step S12).

  When it is determined that the suspicious vehicle is a registered vehicle (YES in step S12), the communication target setting unit 14 ends the process without setting the police as a target of voice communication. This is because even if the following degree is high, it is not unnatural if it is a registered vehicle, and there is no need to start voice communication with the police.

  On the other hand, when it is determined that the suspicious vehicle is not a registered vehicle (NO in step S12), the communication target setting unit 14 outputs a voice message notifying that the suspicious vehicle exists via the voice output device 7. (Step S13) A button for starting voice communication between the own vehicle and the police through the wide area wireless communication device 3 is displayed on the display device 6 (Step S14).

  In this way, the communication target setting unit 14 can enable the passenger of the own vehicle to easily and quickly start voice communication with the police. The communication with the police may be not only voice communication but also data communication. In this case, the host vehicle may transmit the vehicle identification number of the suspicious vehicle to the police.

  With the above configuration, the nearby vehicle monitoring apparatus 100 notifies the passenger of the own vehicle of information related to the nearby vehicle that travels in the vicinity of the own vehicle for a predetermined time or longer. Is a vehicle driven by an acquaintance or a suspicious vehicle.

  In addition, since the nearby vehicle monitoring device 100 sets a nearby vehicle that travels in the vicinity of the host vehicle for a predetermined time or more as a communication partner, a passenger of the host vehicle can quickly and easily determine the vicinity of the vehicle as necessary. Communication with the vehicle can be started.

  The nearby vehicle monitoring device 100 sets the acquaintance's vehicle as the communication partner when the acquaintance's vehicle traveling in the vicinity of the own vehicle for a predetermined time or more departs from the vicinity range. Can quickly and easily initiate communications with acquaintances as needed.

  In addition, since the nearby vehicle monitoring device 100 sets the police as a communication partner when there is a suspicious vehicle that travels in the vicinity of the own vehicle for a predetermined time or more, the passenger of the own vehicle, if necessary, You can start communication with the police quickly and easily. As a result, the nearby vehicle monitoring device 100 can prevent crimes.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, the nearby vehicle monitoring device 100 determines the presence or absence of a suspicious vehicle based on the tracking degree of a specific nearby vehicle and the travel record of the host vehicle, but there is a possibility that the suspicious vehicle is being tracked. After notifying the occupant of the vehicle that the vehicle is in question, only if the degree of follow-up remains above the specified value despite taking action to avoid the suspicious vehicle (such as changing the route). A button for starting communication with the police may be displayed. This is to prevent erroneous determination.
