However, the signal transmission device could be a DSCR (Dedicated Short Range Communications) device, a beacon or fixed-point marker or guide beam transmitter, or another type of signal transmission device. The road is specified by analyzing a signal transmitted by one of these signal transmission devices, which contains different information for each specified position.

[0069] Information about the road specification unit 71 The specified street is stored in the area information storage unit. 74 stored as a street ID.

[0070] The movement direction determination unit 72Determines the incoming or outgoing direction, or entry or exit direction, of the movement path. Optional methods for determining the direction of movement can be used, such as determination based on a change in the user's own position over time, and determination based on information received from ETC, DSRC, beacon, or other signal transmission devices described above. Information specifying the direction of movement (hereinafter also referred to as movement direction information) is stored in the area information storage unit. 74 saved.

[0071] The defined area specification unit 73 specifies the particular area 103 , if the vehicle 4 enters or enters this specific area. The specific area 103is a predefined area on a street. The notification system 1 Each process is carried out in response to the vehicle's movement. 4 in this area. The defined-range storage unit 75 It stores information about a multitude of specific areas and specifies a particular area into which the vehicle enters or drives, from among the multitude of specific areas.

[0072] The specific area 103 can be divided into a multitude of small areas, such as in Fig. Figure 4 illustrates this. In this case, a small area into which the vehicle enters is specified. Fig. 4 are an area A, which is separated from the border area 102a up to the border area 102b sufficient, an area B, which is separated from the border area 102b up to the border area 102c extends, and an area C that is bordered by the border area 102 to the border area 102dSufficient, provided. In other words, areas A to C are specified as distinct, specific areas.

[0073] Optional methods for specifying the specified area can be used, such as (i) a specification based on a comparison between the vehicle's position and map information about the specified area (such as information about the latitude / longitude of each boundary area). 102 ), and (ii) a specification based on ETC, DSCR, beacon or other signal transmission equipment operating in the border areas 102 are provided, received information.

[0074] Information about the multitude of specific areas is stored in a database of the specific area storage unit. 75as described above. Information used for specification by method (i) is map information showing the respective extents of the specified areas. The map information for each specified area is stored with specified area IDs associated with the corresponding specified areas.

[0075] Information used for specification by method (ii) is information indicating correlations between the specified areas and information contained in signals received by the signal transmission devices to specify the fixing or setting positions of the signal transmission devices (information indicating ICs (interchanges; traffic nodes) that the vehicle has passed through in an ETC case). The specified areas are stored together with the corresponding specified area IDs similarly to method (i).

[0076] The database of the designated storage unit 75 Stored information can be updated as needed. For example, new data can be downloaded or obtained from a recording medium connected to the dedicated storage unit. 75 is connected.

[0077] The defined range specification unit 73 The specified area IDs are stored in the area information storage unit. 74 saved.

[0078] As described above, the information gathering unit procures 41 Movement area information. The movement area information obtained in this way is stored in the area information storage unit. 74 saved.

[0082] A street ID, direction of travel information, and a destination ID can be combined into one or two sets of information. For example, if the respective distinctions of a street, a direction of travel, and sections of a street are combined into a destination ID, only the destination ID is required as the area of ​​travel information. Other information can be included in the combined information.

[0083] The information gathering unit 41 can be configured to obtain movement area information before the entry detection unit 44 the vehicle's entry 4 determined in the specific area, or when the entry detection unit 44 the vehicle's entry 4 determined in the specific area. (2) Immediate stop notification level

[0084] The following is a function of the notification system. 1 described, which is carried out when the vehicle 4 the movement ends or stops.

[0085] First, processes that are carried out by the information processing system are described. 5 to be carried out on each of the vehicles 4 is carried along.

[0086] The stop detection unit 46 detects a vehicle stopping 4 or a condition in which the vehicle 4 It is difficult to continue normal movement based on an output from sensors attached to the vehicle. 4 These states can be detected by recording signals associated with the end of the vehicle's movement or stopping.

[0087] More precisely, a stop of the vehicle 4detected on the basis of a signal that, for example, indicates a predetermined threshold or a lower vehicle speed 4 (such as 5 km / h or less). Alternatively, the state in which it displays the vehicle 4 It is difficult to continue normal movement, detectable on the basis of a signal that, for example, indicates an abnormal condition of the vehicle. 4 or a driver, such as the activation of an airbag, a tire blowout, or the activation of an emergency switch.

[0088] The following description describes the detection of the preceding signal by the stop detection unit. 46 This refers to the detection of the end of a vehicle's movement, a stop in its movement, or the halting of its movement. A vehicle stopping its movement is also abbreviated as a vehicle halt.

[0089] The first transmission unit 47 transfers to the server setup 2 a first stop signal including area of ​​travel information stored in the area information storage unit 74 The stored location information about the vehicle 4 , which are detected by the position detection unit 42 was recorded, and specification information, if the stop-and-go unit 46 a halt in the vehicle's movement 4 Detected. Accordingly, the first stop signal is triggered in response to the vehicle coming to a halt in its movement. 4 transmitted.

[0090] The following describes a process that begins with server setup. 2 is carried out.

[0091] The pause information storage unit 62It stores movement area information, position information, and specification information contained in the first stop signal, in association with each other, when a first stop signal is received from the first transmission unit. 47 is transmitted, is received.

[0092] The signal generation unit 63 It generates a second stop signal based on the received first stop signal. The second stop signal includes information about the stopping position of the vehicle. 4d More precisely, the second stop signal can contain part or all of the movement area information, or it can contain the first stop signal (latitude / longitude information). Alternatively, the second stop signal can contain both movement area information and the first stop signal.

[0093] The signal generation unit 63can define one or more areas in accordance with the distance from a starting point according to the current position of the stationary vehicle. 4 based on information contained in the first stop signal (movement area information or first stop signal) which indicates the current position of the vehicle 4 displays, sets, and a second stop signal including area information indicating the area, as information about the vehicle's stopping position. 4 generate.

[0094] The signal transmission target determination unit 64 defines a transmission destination to which the second stop signal is transmitted. The signal transmission destination definition unit 64 includes a transmission target specification unit 64a , which the information processing system 5 specified as a transmission target, and a transmission range definition unit 64b, which defines a fixed area as a transmission target.

[0095] In a specific example, the transmission target specification unit specifies 64a based on movement area information stored in the vehicle information storage unit 61 stored, the information processing system 5 , which is attached to the vehicle 4 is carried along, which is positioned behind the stationary vehicle in the direction of travel. 4 located, in relation to a starting point according to the position of the stationary vehicle 4 , which is contained in the first stop signal.

[0096] In a specific example, the transmission range definition unit defines 64b a fixed area based on the position of the stationary vehicle 4 , which is contained in the first stop signal, and broadcasts or emits the defined fixed area.

[0097] It goes without saying that, apart from these examples, other methods can be used to specify a transmission target. The one attached to the vehicle 4 , which is located near the stationary vehicle 4 located, carried information processing system 5 or the information processing system 5 that on the vehicle 4 is carried along, so that it is within the same specific area as the area of ​​the stationary vehicle. 4 or a specific area located near the same specific area, can, for example, be specified as a transmission target.

[0098] The second transmission unit 65 transmits the second stop signal to the transmission target specified by the signal transmission target determination unit. 64was determined. Information is sent from the signal transmission and receiving device to broadcast the second stop signal. 3 to all information processing systems 5 transmitted, which are located within an area connected to the signal transmission and reception facilities 3 It can be communicated (in a manner similar to, for example, a so-called earthquake warning announcement via telephone). Alternatively, transmission via, for example, FM multiplex radio can be used. (3) Warning level

[0099] The following processes are executed when the other vehicle 4 as the own vehicle 4 Movement ended.

[0100] The receiving unit 49 receives a second stop message, which is from the server setup. 2 is transferred.

[0101] The relationship investigation unit 50determines a positional relationship between the stationary other vehicle 4 and the own vehicle 4 based on information about a stopping position contained in the second stopping signal sent by the receiving unit 49 was received, and travel area information via the own vehicle 4 , which are in the area information storage unit 74 is included. In other words, the relationship determination unit determines 50 , whether the private vehicle 4 is located within a notification distance of the stationary other vehicle (hereinafter also referred to as being in the notification area).

[0102] More precisely determined when the vehicle 4d in Fig. 4 continues, the relationship investigation unit 50 of the vehicle 4c, which is located within area B, is moving in the same direction of travel and is behind the vehicle 4d is positioned so that the own vehicle 4 located within the notification area or notification zone. The relationship investigation unit 50 of the vehicle 4 , which is located at a different location than the preceding one, determines that the own vehicle 4 not located within the notification area. This investigative procedure is presented only as an example. The relationship investigation unit 50 of the vehicle 4b can, for example, determine that the owner's vehicle 4b is located within the notification area.

[0103] The processing execution unit 51 executes a process that is predetermined in accordance with a result of the investigation by the relationship investigation unit. 50was determined. For example, the processing execution unit (PSU) provides 51 a warning is issued to the driver if it is determined that the vehicle is... 4 within the notification area. More precisely, the processing execution unit 51 for example, a warning screen on the display of the navigation system. 25 display or sound a warning tone from the speaker 26 In this case, a warning can be issued based on the distance from the stationary vehicle. 4 be given.

[0104] A control mechanism other than issuing a warning to the driver is possible for the vehicle. 4 Various types of controls can be implemented to adapt the vehicle. 4 to allow passage around a vehicle that has come to a safe stop.

[0105] Even if it is determined that the vehicle is outside the notification area, a warning will be issued for subsequent entry into area B after continued movement.

[0106] The relationship determination unit described above 50 It can be configured to determine whether the vehicle is ahead of the other stationary vehicle in its direction of travel. In this case, the processing execution unit can 51 be configured to terminate the execution of the preceding process when the relationship discovery unit 50 It was determined that the vehicle in question is in front of the other vehicle in the direction of travel.

[0107] The exit investigation unit 52 determined whether the vehicle 4 from a specific area 103has exited or left the designated area. Optional methods for determining exit from the designated area may be used, such as determination based on a comparison between the vehicle's own position and map information about the designated area that was previously stored, and determination based on information from ETC, DSRC, beacon, or other signal transmission devices described above, which are located in the boundary areas. 102 are provided, is received. Accordingly, an investigation can be carried out using a method similar to the procedure of the entry investigation unit. 44 be performed.

[0108] The output signal transmission unit 53 transmits an exit signal, including specification information, to the server facility. 2 , if the exit investigation unit 52 determined that the vehicle 4from a specific area 103 has resigned or left the organization.

[0109] The extinguishing control unit 66 server setup 2 deletes from the vehicle information memory 161 the movement area information associated with the specification information contained in the output signal, when the output signal transmission unit 53 The received exit signal is received. [1-3. Processing]

[0110] Below is a specific processing example from the notification system. 1 The process is described. In accordance with the present embodiment, the notification system notifies 1 Vehicles in the vicinity of the notification system 1 , when a vehicle moving along a predetermined highway stops moving. (1) Vehicle-side main process

[0111] Below is a main vehicle-side process that is handled by the CPU. 32 the information processing facility 31 is executed with reference to a Fig. The process is described in the flowchart shown in Figure 5. This exemplary process begins in response to the commencement of vehicle movement (a state in which the vehicle speed exceeds a predetermined threshold).

[0112] In S1 the CPU determines 32 The system checks whether the vehicle has passed through a predetermined entry ETC gate of a predetermined highway. If it is determined that the vehicle has not yet passed through the entry ETC gate (S1: NO), S1 is repeated. In other words, the CPU waits. 32the process continues to S2. If it is determined that the vehicle has passed through the entrance ETC gate (S1: YES), the process proceeds to S2.

[0113] In S2 the CPU starts 32 A stop investigation process. The stop investigation process is executed in parallel with the ongoing process. The stop investigation process is described in detail below.

[0114] The CPU stores data in S3. 32 A name of an intersection (JCT) or a traffic junction (IC). In the case of a transition from a motorway that does not receive notification from the notification system. 1 needs to access a highway that requires notification through the notification system 1 If required after passing through an intersection, the name of an intersection is stored instead of the name of a traffic junction.

[0115] At the time of a transition from S2 to S3, a traffic junction name is obtained based on ETC information. Conversely, at the time of a transition from S12 or S2 to S3, a traffic junction or intersection name is obtained as a result of determining whether the corresponding traffic junction or intersection has passed through, based on the movement position of the vehicle specified in terms of map matching. Passing through in this context also includes traveling on a main line without passing through a traffic junction or intersection.

[0116] The CPU stores data in S3. 32 The information obtained serves as information to specify a road on which the vehicle is traveling (road ID), and information to specify an area or region in which the vehicle is traveling on the road (destined area ID).

[0117] In S4, the CPU determines 32 an inward or outward direction as the direction of travel of the vehicle and stores the determined direction.

[0118] The direction of movement can be determined based on a change in one's own position over a period of time.

[0119] In S5, the CPU transfers 32 an entry signal to the server setup 2 The entry signal includes information about the movement area and information to specify the information processing system. 5 (Information processing facility) 31 ) (Vehicle ID). The movement area information is information that includes the street ID, the destination ID, and the direction of movement described above.

[0120] Server setup 2, which has received the movement area information, transmits it to the information processing system 5 of the vehicle in question a second stop signal A including information about a first vehicle stop flag to indicate whether the stopped vehicle is within an area or region defined on the basis of the movement area information (S27 in Fig. 6). In the Fig. In the example shown, areas A to C can be determined as the preceding area if the vehicle 4d its movement ends or stops. The area can be defined together with a distinction of the direction of movement.

[0121] In S6 the CPU receives 32 the second stop signal A from the server setup 2 The CPU 32Based on the information about the first vehicle stop flag, sets the first vehicle stop flag to the on state or the off state.

[0122] In S7, the CPU determines 32 The process checks whether the first vehicle stop flag is in the off state. If it is determined that the first vehicle stop flag is in the off state (S7: YES), i.e., if the stopped vehicle is not present in the predetermined area, the process proceeds to S8. If it is determined that the first vehicle stop flag is not in the off state (S7: NO), i.e., if the flag is in the on state, the process proceeds to S10.

[0123] In S8 the CPU checks 32 , whether a new second stop signal B, which is from the server setup 2 The second stop signal B is a signal transmitted by the server setup. 2 is transmitted when the vehicle stops again (S50 in Fig. 9), and includes a second vehicle stop flag that indicates whether the stopped vehicle is present. If it is determined that the second stop signal B has been received, the second vehicle stop flag is set to the "on" state.

[0124] In S9, the CPU determines 32 The process checks whether the second vehicle stop flag is in the off state. If the second vehicle stop flag is in the off state (S9: YES), i.e., if the stopped vehicle is not present in the predetermined area, the process proceeds to S11. Conversely, if it is determined that the second vehicle stop flag is not in the off state (S9: NO), i.e., if the flag is in the on state, the process proceeds to S10.

[0125] In S10 the CPU begins 32 A warning process. The warning process is executed in parallel with the running process. The warning process is described in detail below.

[0126] In S11 the CPU determines 32 Whether the vehicle has passed through or traversed a boundary zone. A boundary zone is a boundary between a multitude of areas corresponding to subdivisions of the transportation network and can correspond to, or be located near, an intersection or traffic junction. The CPU 32 This determination is carried out, for example, on the basis of a condition in which the vehicle's position has crossed the boundary, with reference to GPS information or the reception of a signal from a fixed short-range wireless communication device such as ETC.

[0127] In accordance with the in Fig. The example shown in section 4 is a crossing at each of the border areas. 102a , 102c and 102d positioned while a traffic junction is located at the border area 102bis positioned. In S11, a passage or drive through any of the boundary areas is possible. 102 determined.

[0128] If it is determined that the vehicle has passed through the boundary area (S11: YES), the process proceeds to S12. If it is determined that the vehicle has not passed through the boundary area (S11: NO), the process returns to S8.

[0129] In S12 the CPU determines 32 The process checks whether the vehicle has passed through an ETC exit gate of the expressway. If it is determined that the vehicle has not yet passed through the ETC exit gate (S12: NO), i.e., if the vehicle crosses the boundary and enters another area on the expressway, the process returns to S3. In this case, a new destination ID is assigned in S3.

[0130] If it is determined that the own vehicle has passed through the ETC exit gate (S12: YES), i.e., if the own vehicle crosses the boundary area and leaves the expressway, the process proceeds to S13.

[0131] In S13, the CPU deletes 32 The ID information about the traffic junction or intersection and information about the direction of travel stored in S3 and S4. The CPU 32 Furthermore, it transmits an exit signal to the server facility, indicating the need to delete the preceding information. 2 Server setup 2 deletes the movement area information transmitted in S5.

[0132] In S14 the CPU terminates 32 The arrest investigation process, which began in S2, and the warning process, which began in S10. Afterwards, the process returns to S1. (2) First server response process

[0133] Below is a sample from the CPU 11 server setup 2 executed first server response process with reference to a flowchart in Fig. 6. This process is described during the operation of the server setup. 2 executed continuously.

[0134] In S21, the CPU checks 11 the reception of an entry signal (movement area information and vehicle ID) from the information processing unit 31 , which is carried on any of the vehicles, in S5 in Fig. 5 to the server setup 2 was transmitted. If it is determined that the entry signal has not yet been received (S21: NO), S21 is repeated. If it is determined that the entry signal has been received (S21: YES), the process proceeds to S22.

[0135] In S22 the CPU updates 11A list of areas based on information received in S21. As in Fig. As shown in Figure 7, the area list is a list for movement management, which is used for each of the areas as subdivisions of the specified area. 103 The area list, which is also subdivided according to the direction of travel, stores vehicle IDs of vehicles moving within the corresponding area. Accordingly, the area list itself includes a street ID, a designated area ID, and travel direction information. The respective area lists are stored in the vehicle information storage unit. 61 saved.

[0136] The CPU 11 S22 specifies a movement area based on the movement area information and stores vehicle IDs (phone numbers in Fig. 7), which are included in the territory list of the relevant territory. An entry signal is transmitted similarly when a vehicle enters another territory. In this case, the corresponding vehicle ID is moved to the territory list of the other territory, as indicated by arrows in Fig. 7 is indicated.

[0137] To store vehicle IDs, the respective vehicle IDs are assigned such that a newer vehicle ID with a lower priority is stored. The priority in this context is the order in which the second stop signal B is transmitted in S50. Fig. 9, which is described below.

[0138] In S23 the CPU determines 11 Whether the server is in a vehicle stop mode. The vehicle stop mode refers to a state in which stopping a vehicle within the specified area is not possible. 103 occurs, which is caused by the server setup 2is managed, which triggers the on state of a predetermined flag. The vehicle stop mode is described in S51 in Fig. 9 switched on.

[0139] If the server is in vehicle stop mode (S23: YES), the process proceeds to S24. If the server is not in vehicle stop mode (S23: NO), the process proceeds to S26.

[0140] In S24, the CPU determines 11 , whether the vehicle's position, specified based on movement area information contained in the entry signal received in S21, is within a stop signal distribution area. More precisely, it is determined whether an area flag in S46 is present in the area list after the vehicle IDs have been updated in S22. Fig. 9, as described below, has been set to the ON state.

[0141] If the vehicle's position is within the stop signal distribution area (S24: YES), the process proceeds to S25. If the vehicle's position is not within the stop signal distribution area (S24: NO), the process proceeds to S26.

[0142] In S25 the CPU 11 A second stop signal A is set, containing information to set the first vehicle stop flag to the "on" state, information indicating the vehicle stop position according to a trigger to activate the vehicle stop mode, and the vehicle ID of the corresponding vehicle. The process then proceeds to S27.

[0143] In S26 the CPU 11 A vehicle non-stop signal is set, which contains information for setting the first vehicle stop flag to the off state. The process then proceeds to S27.

[0144] In S27, the second stop signal A or the vehicle non-stop signal is transmitted to the vehicle (information processing unit) according to a transmission source of the movement area information received in S91. 31 ) transferred. The process then returns to S21. (3) Detention investigation process

[0145] Below is a sample from the CPU 32 the information processing facility 31 carried out arrest investigation process with reference to a Fig. The flowchart shown in section 8 describes this process. It begins in S2 of the vehicle-side main process in... Fig. 5.

[0146] In S31 the CPU determines 32Whether the vehicle has finished moving or stopped. In this example, a stop of the vehicle is determined based on a state in which the vehicle's speed is 5 km / h or less. If it is determined that the vehicle has not stopped (S31: ON), S31 is repeated. In other words, the CPU waits 32 until the vehicle comes to a stop. If it is determined that the vehicle has stopped (S31: YES), the process proceeds to S32.

[0147] In S32, the CPU procures 32 GPS position information. This position information includes the latitude and longitude of the stopping position.

[0148] In S33, the CPU places 32a first stop signal including GPS position information obtained in S32, a vehicle ID, a road ID and a designated area ID obtained in the last step in S3, and direction of travel information obtained in the last step in S4, fixed.

[0149] In S34, the CPU transfers 32 the first stop signal to the server facility as specified in S33 2 .

[0150] In S35, the CPU determines 32 Whether the vehicle's movement has restarted or resumed. In this example, a restart of movement is determined based on a state where the vehicle's speed is 30 km / h or higher. If it is determined that movement has not yet resumed (S35: NO), S35 is repeated. In other words, the CPU waits 32until the vehicle restarts. If it is determined that movement has resumed (S35: YES), the process proceeds to S36.

[0151] In S36, the CPU transfers 32 Information indicating that a vehicle stop has been lifted is sent to the server facility. 2 The information indicating a vehicle stop release or a reversal of the vehicle stop includes the vehicle ID, on the basis of which the server setup 2 The process detects the vehicle's ability to be stopped based on its vehicle ID. After S36, the process returns to S31. (4) Second server response process

[0152] Below is a second server response process, which is handled by the CPU. 11 server setup 2 is executed with reference to a Fig. The flowchart shown in section 9 describes this process. This process occurs during the operation of the server setup. 2executed continuously.

[0153] In the S41, the CPU determines 11 Whether a first stop signal has been received. The first stop signal is received by the information processing unit. 31 The information is transferred to S34 of the stop detection process. If it is determined that the first stop signal has been received (S41: YES), the process proceeds to S45. If it is determined that the first stop signal has not yet been received (S41: NO), the process proceeds to S42.

[0154] In S42 the CPU determines 11 whether a notification command has been received. The notification command is sent by the other server. 2in S49, which is described below. If it is determined that the notification command has been received (S42: YES), the process proceeds to S50. If it is determined that the notification command has not yet been received (S42: NO), the process proceeds to S43.

[0155] In S43 the CPU determines 11 Whether information indicating that the vehicle stop has been released has been received. The release of the vehicle stop is carried out by the information processing unit. 31 The information is transferred to S36 of the stop investigation process. If it is determined that information indicating the vehicle's stop has been received (S43: YES), the process proceeds to S52. If it is determined that information indicating the vehicle's stop has not yet been received (S43: NO), the process proceeds to S44.

[0156] In S44, the CPU determines11 Whether a cancellation command, deletion command, or erasure command has been received. The cancellation command is issued by the other server. 2 The information is transferred to S55, which is described below. If it is determined that the cancellation order has been received (S44: YES), the process proceeds to S54. If it is determined that the cancellation order has not yet been received (S44: NO), the process returns to S41.

[0157] In S45, the CPU is specified 11 from a multitude of area lists, an area list is selected that contains the vehicle ID (telephone number) of the first stop signal identified in S41 as a received signal.

[0158] In S46, the CPU 11An area flag from the area list specified in S45 is set to the "on" state. This area flag is set to "on" when a vehicle stops within the corresponding area. In S46, GPS position information contained in the received initial stop signal is stored in the area list in association with the vehicle ID as information indicating the stop position.

[0159] In S47, the CPU selects 11A distribution area for a second stop signal B. This distribution area is determined in advance in accordance with the area list, whose area flag in S46 has been set to the "on" state. More precisely, in this step, the area according to the preceding area list and an area located behind the selected area in the direction of travel are chosen, i.e., an area in which a vehicle is moving in the direction towards the location of the stopped vehicle.

[0160] The CPU places 48 11 a second stop signal B including information on setting the second vehicle stop flag to the on state, and the stop position information and vehicle ID contained in the first stop signal.

[0161] In S49, the CPU transfers 11 a notification command to the server setup 2, which is located in the distribution area selected in S46. The notification command is a command that activates the corresponding server setup. 2 This causes the server to transmit the second stop signal B. Accordingly, the server transmits 2 , which received the notification command in S42, the second stop signal B even if a vehicle stops in an area other than that of the server facility 2 occurs in the corresponding distribution area.

[0162] In S50, the CPU distributes 11 The second stop signal B is issued to vehicles located within the area list of the area selected as the distribution area. In other words, the vehicles within the area list correspond to vehicles (information processing facilities). 31) with vehicle IDs registered in the area list. The second stop signal B is distributed using telephony in the order of the distribution priority defined in the area list.

[0163] In S51 the CPU switches 11 The vehicle stop mode is activated. Afterwards, the process returns to S41.

[0164] A process in S52 is executed when it is determined that information indicating the vehicle's stop has been received in S43. In S52, the CPU selects 11 From the multitude of area lists, an area list is selected that contains the vehicle ID, which is included in the information indicating the vehicle's suspension is lifted and was determined in S43 as received information.

[0165] In S53, the CPU 11 The area flag of the area list selected in S52 is set to the off state. In this step, the CPU deletes 11Furthermore, GPS position information was stored in the area list in S46.

[0166] In S54, the CPU 11 The cancellation information, including the stopping position and vehicle ID of the vehicle, is determined according to the transmission source of the vehicle stop cancellation signal received in S43. The cancellation information indicates that the stopped vehicle is no longer present. The information processing unit 31 terminates the control action that was performed based on the presence of the stationary vehicle, such as a warning, in response to a triggering of the receipt of the preceding cancellation information.

[0167] In S55, the CPU transfers 11 a cancellation or deletion command to the server setup 2, which is located in the distribution area according to the area list selected in S52 (i.e., a distribution area previously selected in S47 based on the vehicle stopping with the same vehicle ID). The cancellation command is a command to transmit the cancellation information to the appropriate server facility. 2 .

[0168] In S56, the CPU distributes 11 The cancellation information. The cancellation information is distributed to the area selected in S47. The server setup. 2 Distributes the cancellation information to vehicles with vehicle IDs that are in the area list of the server facility. 2 are registered in the corresponding area.

[0169] In S57 the CPU switches 11 The vehicle stop mode is deactivated. Afterwards, the process returns to S41. (5) Warning process

[0170] The following is a warning process initiated by the CPU. 32the information processing facility 31 is executed with reference to a Fig. The flowchart shown in section 10 describes this process. This process begins in section S10 within the vehicle-side main process. Fig. 5. At the start of the process, the first vehicle stop flag and / or the second vehicle stop flag is set to the "on" state.

[0171] In S61, the CPU determines 32 The process checks whether the second vehicle stop flag is in the "on" state. If the second vehicle stop flag is in the "on" state (S61: YES), the process proceeds to S62. If the second vehicle stop flag is not in the "on" state (S61: NO), meaning the first vehicle stop flag is in the "on" state, the process proceeds to S63.

[0172] In S62, the CPU determines 32, whether the vehicle is within the distribution area of ​​the stop signal, and whether the direction of travel is identical or the same, based on the information in S8 in Fig. 5. Received second stop signal B. If it is determined that the direction of travel is the same (S62: YES), the process proceeds to S63. If it is determined that the direction of travel is not the same (S62: NO), this process ends.

[0173] In S63 the CPU stores 32 the received stop signal. As the process progresses from S61 to S63, this is reflected in S6. Fig. 5 received second stop signal A stored. If the process progresses from S62 to S63, this is stored in S8. Fig. 5 received second stop signal B stored.

[0174] In S64, the CPU calculates 32the distance between the position of the own vehicle and the stopping position, which is contained in the stop signal stored in S63, based on the position of the own vehicle and the stopping position.

[0175] In S65, the CPU 32 A warning is issued in accordance with the distance calculated in S64. Specific examples of the procedure for issuing the warning include displaying the notification of the vehicle stopping on the navigation system's display. 25 , and voice guidance from the loudspeaker 26 .

[0176] The CPU 32 Furthermore, it sets a color and size for the notification so that content displayed on the display device (such as characters) becomes more noticeable as the distance decreases. The CPU 32 increases the volume of voices coming from the speaker 26A warning tone is emitted when the distance decreases, and a warning tone is emitted when the distance is short. Warning modes that change according to the distance, like the preceding examples, can be implemented in various ways.

[0177] The emission or output of a warning can be configured to end when the calculated distance between the stopping position and the vehicle's own position is shorter than a predetermined threshold.

[0178] In S66, the CPU determines 32 The process checks whether the vehicle has passed through the stopping position of the other vehicle, which is contained in the stop signal stored in S63. If it is determined that the vehicle has passed through the stopping position (S66: YES), the process proceeds to S68. If it is determined that the vehicle has not yet passed through the stopping position (S66: NO), the process proceeds to S67.

[0179] In S67 the CPU determines 32 Whether the cancellation information has been received. The cancellation information is displayed in S56 in Fig. 9. If it is determined that the cancellation information has been received (S67: YES), the process proceeds to S68. If it is determined that the cancellation information has not been received (S67: NO), the process returns to S64.

[0180] In S68, the CPU 32 The vehicle stop flag is switched to the off state. More precisely, the CPU changes this. 32The vehicle stop flag, which had been set to the "on" state when the vehicle stopped, is set to the "off" state based on the current state of the corresponding vehicle, which does not require a warning. More precisely, when the process progresses from S66 to S68, i.e., when it is determined that the vehicle has passed the stopping position of the other vehicle, the vehicle stop flag associated with that stopping position is set to the "off" state. Conversely, when the process progresses from S67 to S68, the vehicle stop flag associated with the vehicle ID contained in the received cancellation information is set to the "off" state.

[0181] In S69 the CPU terminates 32 The warning. After that, the process returns to S61. [1-4. Beneficial Effects]

[0182] In accordance with the first embodiment, the following advantageous effects are provided. [1A] The information processing system 5 According to the present embodiment, movement area information is obtained by the information acquisition unit. 41 and stores the movement area information in advance in the area information storage unit. 74 The information processing system 5 Based on a comparison between the second stop signal B and the stored movement area information, it determines whether a warning is necessary when the receiving unit 49 The second stop signal B is received. This structure eliminates the need to gather information about the vehicle's area of ​​operation after receiving the second stop signal B, thus enabling a rapid warning execution. [1B] The information processing system 5 According to the present embodiment, the defined range storage unit includes 75 , which stores the information that determines the position of the specific area 103 displays. The information processing system 5 determined whether the vehicle 4 in the specific area 103 has entered or entered, based on a comparison between the position of the vehicle 4 , which are detected by the position detection unit 42 was recorded, and the position of the specific area 103 , which are located in the designated storage unit 75 is stored.

[0183] This structure therefore determines the entry or passage into the specific area. 103 , which is based on the data in the designated storage unit 75The stored position information is defined. In this case, the specific area changes. 103 This can be easily achieved by updating the stored information. Accordingly, a necessary addition, deletion, or modification of a specific area in the event of a change in the shape of the road due to construction work, or the addition of a new specific area due to, for example, a change in traffic volume, is easily implemented. [1C] The information processing system 5 According to the present embodiment, the wireless signal receiving device includes 21 , which receives a wireless signal transmitted by a signal transmission device located along the road and transmitting a predetermined wireless signal. The information processing system 5 determined that the vehicle 4 in the specific area 103This has occurred when the wireless signal receiving device 21 receives the predetermined wireless signal.

[0184] Since a signal transmitted by the signal transmission device, such as ETC, DSRC and a beacon, has a limited transmission range, the wireless signal receiving device receives 21 The signal is only triggered when passing through a narrow, predetermined area. In this case, the probability of the signal being detected at a location other than the corresponding road is reduced. Accordingly, entry into the designated area is 103 Determined with high accuracy. [1D] In accordance with the information processing system 5 In the present embodiment, the relationship determination unit determines 50Whether the vehicle is in front of another stationary vehicle in its direction of travel. The processing / execution unit 51 The execution of a warning ends when the relationship detection unit 50 It was determined that the vehicle in question is in front of the other vehicle in the direction of travel.

[0185] This structure reduces unnecessary warnings given based on the presence of a stationary vehicle behind the driver's vehicle, thus avoiding a disturbance that would otherwise impair comfortable driving. [2. Second embodiment][2-1. Differences compared to the first embodiment]

[0186] The basic structure of a second embodiment is similar to that of the first embodiment. Therefore, similar configurations are not explained again. Only differences between these embodiments are addressed.

[0187] According to the first embodiment described above, movement area information and a vehicle ID, which are stored in S21 in the first server response process, are Fig. The received entry signal contains six elements, which are classified and processed for each area within a specific region. However, in accordance with the present embodiment, this information and signal are broadcast or transmitted to a predetermined area without classification for each region and without transmitting a second stop signal B to a specific vehicle ID. [2-2. Processing]

[0188] Below is a specific processing example of the notification system. 1 as described in the second embodiment. Only the first server response process and the second server response process in the present embodiment differ from the respective processes in the first embodiment. Accordingly, other processes are not explained again here. (1) First server response process

[0189] Below is an initial server response process, which is performed by the CPU. 11 server setup 2 is executed with reference to a Fig. The flowchart shown in section 11 describes the steps in this process, which correspond to the steps in the first server response process in Fig. Since the reference numerals in the first embodiment are similar in 6, the same reference numerals are given, and part of the explanation is omitted.

[0190] After S21 of the first server response process, the process proceeds to S23, while S22 is skipped. If S23 determines that the current operating mode is a vehicle stopping mode (S23: YES), the process proceeds to S71.

[0191] In S71, the CPU determines 11 Whether the position of the vehicle specified based on the movement area information contained in an entry signal received in S21 is within a stop signal distribution area. The stop signal distribution area is an area to which information indicating a vehicle stop is sent at the time the vehicle stops within that specific area. 103 is distributed. The stop signal distribution area is in S82 in Fig. 12, which is described below.

[0192] If the vehicle is within the stop signal distribution area (S71: YES), the process proceeds to S25. If the vehicle is not within the stop signal distribution area (S71: NO), the process proceeds to S26. (2) Second server response process

[0193] Below is a second server response process, which is handled by the CPU. 11 server setup 2 is executed with reference to a Fig. The flowchart shown in section 12 describes the steps in this process, which correspond to the steps in the second server response process in [section / document]. Fig. Since the reference numerals in the first embodiment are similar, the same reference numerals are given, and part of the explanation is omitted.

[0194] If it is determined that an initial stop signal has been received in S41 (S41: YES), the process proceeds to S81. If it is determined that a notification command has been received in S42 (S42: YES), the process proceeds to S84. If it is determined that information about the vehicle's stop being lifted has been received in S43 (S43: YES), the process proceeds to S85. If it is determined that a release command has been received in S44 (S44: YES), the process proceeds to S86.

[0195] The CPU stores data in S81. 11 the first stop signal identified as a received signal in S41, and a vehicle ID of the information processing unit 31 , which is a transmission source, in association with each other.

[0196] In S82, the CPU selects 11 a distribution area for a second stop signal B.

[0197] The following is a procedure for selecting the distribution area with reference to Fig. 13 described. The vehicle 4 is a vehicle that travels on a highway 111 has ended. The expressway 111 exhibits a boundary located in each of areas C where transport hubs (IC) 112 ( 112a until 112c ) and an intersection (JCT) EE113 are provided. The expressway 111 is in an area 1, which is bordered by a traffic junction ( 1 ) to an intersection ( 2 ) extends to an area 2, which is bordered by the intersection ( 2 ) to a traffic junction ( 3 ) extends, and an area 3, which is bordered by the transport hub ( 3 ) to a traffic junction ( 4 ) is sufficient, subdivided.

[0198] The signal transmission and reception device 3 (one of 3a until 3cThe signal transmission and reception equipment, which distributes the signals, is provided for each area or region. 3b Distributes signals to area 1. The signal transmission and receiving equipment 3b Distributes signals to area 2. The signal transmission and receiving equipment 3c Distributes signals to area 3. It goes without saying that each of the signal transmission and receiving facilities 3a until 3c It can distribute signals to an area extending beyond the preceding area, creating an overlapping distribution area. Each of the server facilities 2 ( 2a until 2c ) is adjacent to the corresponding signal transmission and reception equipment 3 arranged.

[0199] The vehicle 4 stops along the course of area 2 in the direction towards the intersection ( 2). In this case, there is a vehicle that is present in area 1 and is in front of the vehicle in the direction of travel. 4 or is located on a road with a different direction of travel, in a state of low urgency for receiving the vehicle stop information. Accordingly, the distribution area is defined as areas 2 and 3, which are distinct from area 1.

[0200] In S83, the CPU 11 A second stop signal B, including information on setting a second vehicle stop flag to the "on" state, the distribution areas, the direction of travel, and information about the stop position and the vehicle ID contained in the first stop signal, is set. The process then proceeds to S49.

[0201] After the completion of S49, the process continues to S84.

[0202] In S84, the CPU broadcasts 11The second stop signal B. After that, the process continues to S51.

[0203] In S85, the CPU selects 11 The distribution areas selected in S82, i.e., the distribution areas that received a broadcast transmission in S84. The process then proceeds to S54.

[0204] After the completion of S55, the process continues to S86.

[0205] In S86, the CPU broadcasts 11 Cancellation information. The process then proceeds to step 357. [2-3. Beneficial Effects] [2A] In accordance with the notification system 1 In the present embodiment, the server setup 2 based on a signal from the information processing system 5Once a signal has been transmitted, the system identifies an area to which a second stop signal is to be transmitted and transmits the second stop signal to this area. This structure eliminates the need to individually determine the position of the information processing system. 5 Accordingly, an immediate transmission of the second stop signal is achievable, while a processing load is transferred to the server setup. 2 is reduced. [3. Third embodiment][3-1. Differences compared to the second embodiment]

[0206] The basic structure of a third embodiment is similar to that of the second embodiment. Therefore, similar configurations are not explained again. Only differences between these embodiments are addressed.

[0207] In accordance with the third embodiment, the transmission range determination unit64b the signal transmission target determination unit 64 a function is performed. If a first stop signal is received from the first transmission unit, 47 The transmission range setting unit determines whether a transmission or reception occurs. 64b Based at least on the basis of movement area information contained in the first stop signal, a section of a road is defined to which a second stop signal B (stop position area) is transmitted. The second transmission unit 65 The second stop signal B is transmitted by the signal generation unit. 63 was generated, to the stopping position area, which is defined by the transmission range determination unit 64b was determined. [3-2. Processing]

[0208] Below is a specific processing example of the notification system. 1as described in the third embodiment. Only a second server response process and a warning process in the present embodiment differ from the respective processes in the second embodiment. Accordingly, other processes are not explained again here. (1) Second server response process

[0209] The second server response process, which is handled by the CPU, is described below. 11 server setup 2 is executed with reference to a Fig. The flowchart shown in section 14 describes the steps in this process, which correspond to the respective steps in the second server response process in Fig. Since the second embodiment is similar to the reference numerals in section 12, similar reference numerals are given, and part of the description is omitted.

[0210] Once a distribution area for receiving a second stop signal B is selected in S82, the process proceeds to S91.

[0211] In S91, the CPU determines 11 A stopping position range is based on a stopping position and a section. The stopping position range is information that indicates a fixed area and includes information about longitude and latitude. As in Fig. As shown in section 15, there are three areas. 121 , which are divided into a first area 121a , a second area 121b and a third area 121c to be formed in sequence, starting from a starting point corresponding to a stopping position 120 on the street 101 fixed in the rearward direction.

[0212] Optional methods for determining stopping position ranges can be used. The starting point of the ranges need not be at the stopping position but can be a position away from it, with a distance remaining between the starting point and the stopping position. The method for determining the stopping position ranges can be selected for each of the predefined sections. For example, in the case of a section with many curves that requires a reduction in speed, each of the stopping position ranges can be defined as a small area. The stopping position ranges can be specified based on information other than latitude and longitude. The number of ranges can be other than three.

[0213] In S92, the CPU determines 11A warning level is defined for each stopping position area. The specific warning levels are determined according to the degree of danger. For example, the stopping position area located close to the stopping position has a high urgency level. However, the urgency level decreases with increasing distance from the stopping position. Accordingly, appropriate warning levels are defined according to the distance from the stopping position.

[0214] In S93, the CPU 11A second stop signal B, including information for setting a second vehicle stop flag to the "on" state, information about the stop position zones, each with a specific warning level, and a vehicle ID, is defined. The process then proceeds to S49. The information defined therein includes all information about the stop position zones (information about three stop position zones in this embodiment). (2) Warning process

[0215] The following is the information provided by the CPU. 32 the information processing facility 31 executed warning process with reference to Fig. 16 steps are described. These steps correspond to the respective steps in the warning process in Fig. Since the reference numerals in the first embodiment are similar to those in 10, similar reference numerals are given, and part of the explanation is omitted.

[0216] If S61 determines that a second vehicle stop flag is in the ON state (S61: YES), the process proceeds to S101.

[0217] In S101 the CPU determines 32 , whether the position of the vehicle is contained within any of the stopping position ranges in the second stopping signal B, which was determined as a received signal in S8. More precisely, the CPU determines 32 , whether the vehicle is in any of the stopping position areas 121 , which pass through the first area 121a , the second area 121b and the third area 121c in Fig. 15 are formed, is located.

[0218] If the vehicle is located in any of the areas (S101: YES), the process proceeds to S63. If the vehicle is not located in any of the areas (S101: NO), the current process ends.

[0219] After the completion of S63, the process continues to S102.

[0220] In S102, the CPU 32 A warning is issued at a warning level defined for the stopping zone in which the vehicle is located. The process then proceeds to S66.

[0221] If it is determined that cancellation information has not yet been received in S67 (S67: NO), the process proceeds to S103.

[0222] In S103, a positional relationship between the stopping position area and the vehicle's position is verified. The second stopping signal B, which was determined as a received signal in S8, encompasses a multitude of stopping position areas. Accordingly, a change in the position of the moving vehicle from one area to another can be detected based on the determination of the stopping position area containing the vehicle.

[0223] In S104, the warning level is reset. If, based on the check in S103, it is determined that the positional relationship between the stopping position area and the vehicle's own position has changed, the warning level is changed in accordance with the stopping position area and set as a new warning level. The process then proceeds to S102. [3-3. Beneficial Effects] [3A] In accordance with the notification system 1 In the present embodiment, it includes one of the information processing systems. 5 transmitted first stop signal information indicating the current position of the vehicle 4 displays the server setup. 2establishes one or more stopping position ranges in accordance with the distance from a starting point according to the current position of the vehicle based on the information contained in the first stopping position and indicating the current position, and generates a second stopping signal B including information indicating the stopping position range as information about the stopping position of the vehicle.

[0224] The information processing system 5 determined whether the owner's vehicle 4 is located in the preceding area contained in the received second stop signal B, and executes a predetermined process based on an investigation result.

[0225] In accordance with the notification system configured thus 1 transfers the server setup 2Only area information and information indicating warning levels are available. In this case, a rapid transmission of the second stop signal B to the information processing system is required. 5 achievable. Furthermore, the information processing system must 5 only determine whether the vehicle is within the transmitted stopping position area. Accordingly, a process on the information processing system 5 offloads the processing load. [4. Other examples] [4A] In accordance with the embodiments described above, a structure has been presented by way of example that performs the respective processes for a destination of a vehicle traveling on a highway. However, the processes discussed above can be performed for a destination traveling on a road other than a highway.

[0226] Below is an example of a vehicle-side main process that is carried out in this situation, with reference to a [missing information] in Fig. The flowchart shown in section 17 describes the steps in this process, which correspond to the respective steps in the main vehicle-side process. Fig. Since the reference numerals in the first embodiment are similar, similar reference numerals are given, and part of the explanation is omitted.

[0227] In S121 the CPU determines 32 Whether a private vessel has entered a specific area. Methods for this determination can be chosen at will, such as a determination based on a comparison between GPS information showing the private vessel's position and map information showing a specific area (map matching), and a determination based on information received from ETC, DSRC, beacon, or other signal transmission equipment.

[0228] If it is determined that the vehicle has not entered the defined area (S121: NO), S121 is repeated. If it is determined that the vehicle has entered the defined area (S121: YES), the process proceeds to S2.

[0229] After the completion of S2, the process continues to S122.

[0230] In S122, the CPU obtains and stores movement area information, including position information to specify the road and the defined area, and movement area information, including a direction of movement. The process then proceeds to S5. The methods for specifying the road and the defined area can be similar to the method used in S121. The direction of movement can be determined based on a change in the vehicle's own position over time or based on information received from a signal transmission device that transmits signals only to vehicles moving in a defined direction.

[0231] If S9 determines that a second vehicle stop flag is in the off state (S9: YES), or after completion of S10, the process proceeds to S123.

[0232] In S123 the CPU determines32 Whether the vehicle has crossed a boundary zone. Any method can be used to define the boundary zone. For example, an arbitrary point can be set on a boundary zone, or a boundary zone can be defined at any of fixed intervals. Crossing the boundary zone can be determined by a procedure similar to the procedure in S121.

[0233] If it is determined that the vehicle has passed through the limit zone (S123: YES), the process proceeds to S124. If it is determined that the vehicle has not yet passed through the limit zone (S123: NO), the process returns to S8.

[0234] In S124 the CPU determines 32The process checks whether the vehicle has left the defined area. If it is determined that the vehicle has not yet left the defined area (S124: NO), the process returns to S122. If it is determined that the vehicle has left the defined area (S124: YES), the process proceeds to S125. Leaving the defined area can be determined using a procedure similar to the procedure in S121.

[0235] In S125, the CPU erases 32 the movement area information stored in S122 and transmits it to the server facility 2 An exit signal indicates the need to delete the movement area information. The process then proceeds to S14.

[0236] The notification system configured in this way 1 It can be used for various types of roads as well as for a highway. [4B] In accordance with the embodiments described above, position information obtained by the position detection unit 42 was procured and a stopping position for the vehicle 4 The first and second stop signals, A and B, are included for transmission and reception. This indicates the vehicle's stopping position. 4 However, the indicating signal does not necessarily have to be transmitted. For example, if the area of ​​the specific region 103 If the target area is limited to a narrow region, a defined area ID can be used instead of position information. [4C] In accordance with the third embodiment, a stopping position range is defined as a latitude and longitude range based on a stopping position. However, other methods may be used for this definition. For example, a range may be divided into circles. 131 ( 131a until 131c) to the stopping position 120 be subdivided (i.e., in accordance with the distance in a straight line originating from the stopping position), as in Fig. 18 shown.

[0237] Alternatively, stopping position areas can be determined in accordance with an actual distance traveled on the road. 101 based on subdivisions of points that are provided at intervals of, for example, 500 m starting from the stopping position. [4D] The specific area can be classified into a variety of types such that the communication system between the server facility 2 and the information processing system 5 in accordance with the classification of the specific area of ​​entry, it can be changed.

[0238] As in Fig. As shown in 19, an information processing facility is at work. 31aas an area identification unit 54 , which is a type of specific area, which is considered a specific area of ​​entry by the entry detection unit 44 The first transmission unit has been determined, identified. 47 is configured to communicate via communication systems in accordance with a variety of communication standards and to transmit movement area information and the like through the pre-defined communication system in accordance with the type of area identification unit. 54 identified specific area to the server setup 2 to transfer.

[0239] This structure therefore establishes a correspondence between specific areas and communication systems. Various methods can be used to determine the correspondence between specific areas and communication procedures, such as an individual correspondence for each specific area, or a correspondence based on roads, road types, road sections, and other conditions.

[0240] To implement communication using communication methods compliant with a variety of communication standards, the information processing facility can 31a include a variety of communication modules for different communication standards. [4E] In accordance with the embodiment described above, road IDs, direction of travel information, and destination IDs are included in the movement area information. However, not all of these IDs and information are necessarily required for the movement area information, as long as at least one of them is included in the movement area information. For example, a vehicle movement area can be narrowed based on a road ID or a destination ID. Furthermore, a vehicle movement area can be narrowed based on a direction of travel if the signal transmission and receiving equipment 3 Signals transmitted to vehicles have a limited range. [4F] In accordance with the embodiments described above, the server equipment communicates 2 and the information processing system 5about the signal transmission and reception equipment 3 together. The respective information processing systems 5 However, they can be done without the intermediary of the server setup. 2 They can communicate directly with each other, i.e., they can perform vehicle-to-vehicle communication. In this case, the signal transmission and reception equipment can 3 between the respective information processing systems 5 be switched on.

[0241] In accordance with the direct communication between the information processing systems 5 The implementing structure transmits the information processing system 5 , which is carried on the vehicle that has stopped its movement, a first stop signal to the outside, while the information processing system 5 , which is on the other vehicle 4The vehicle being transported receives the first stop signal. The received first stop signal contains information about the stopped vehicle's position. 4 and is therefore treated as a second stop signal, as described in the preceding exemplary embodiments.

[0242] To implement vehicle-to-vehicle communication, the communication module can be used. 36 be configured to periodically and wirelessly transmit data to an unspecified or indefinite number of different information processing facilities 31 to send out information about the transmission source information processing facility 31 (within a communication range of radio or radio waves).

[0243] In each case of communication via the server setup 2, vehicle-to-vehicle communication and road-to-vehicle communication without the intermediary of the server facility 2 The information processing system stores 5 The storage unit contains information about the destinations to which signals are transmitted. In the case of broadcast transmission, destinations are specified at addresses where the respective information processing systems provided on different vehicles are located. 5 be allowed to receive a transmission. [4G] In accordance with the embodiments described above, the information processing system 5 on each of the vehicles 4 carried along. However, arbitrary structures can be used as long as all functional units within the vehicle are present. 4are provided as a system. More precisely, all configurations to enable the function as an information processing system must simply be in accordance with a movement of the vehicle. 4 be mobile. For example, part or all of the information processing system can be installed in the vehicle. 4 spent (or from the vehicle) 4 (taken) are taken.

[0244] In accordance with a specific example of this structure, an information processing device (terminal device), such as a smartphone, can be configured to perform the function of the information processing device. 31 to be carried out in the exemplary embodiments described above. In this case, the vehicle 4an interface device (such as a wireless communication device that communicates with a smartphone) for communicating with devices and sensors (wireless signal receiving device) 21 GPS receiver 22 , steering angle sensor 23 and speed sensor 24 ), which are on the vehicle 4 They should be carried along.

[0245] The respective functions of the information processing facility 31 can be attached to either the vehicle 4 or be provided by a smartphone. A typical smartphone with wireless communication functions such as telephony is capable of performing the functions of the incoming signal transmission unit. 45 , the first transmission unit 47 , the receiving unit 49 and to perform other communication functions. The information gathering unit 41 , the entry investigation unit44 , the stop-and-go unit 46 , the processing execution unit 51 and others can be collectively controlled using a smartphone to ensure smooth processing. [4H] In accordance with the embodiments described above, movement area information is processed by the information processing system 5 Procured. However, movement area information can be obtained through the server setup. 2 be generated.

[0246] More precisely, procured in accordance with an information processing facility 31b of the information processing system 5 a vehicle information acquisition unit 151 Information that displays the status of a vehicle and includes vehicle position information and information about a steering turn, as in Fig. 20 shown. An entry transmission unit. 152transmits a signal including information about the vehicle's states and specification information for the information processing system. 5 as an entry signal to the server facility when the entry detection unit 44 The vehicle's entry into a specific area is recorded.

[0247] On the side of a server setup 2a creates a territory information generation unit 153 Area information based on the information contained in the transmitted entry signal and indicating the vehicle's state. An area information transmission unit. 154 transmits the generated movement area information to the information processing system 5 corresponding to a transmission source that is specified by the specification information contained in the input signal.

[0248] Then it stores information on the side of the information processing system. 5 the area information storage unit 74 The movement area information transmitted by the server facility as information about the movement area of ​​the vehicle 4 .
