  Information on the operation of the vehicle including the stop to the stop or the departure from the stop is acquired in the vehicle and used for management of the operation information. When acquiring information related to operation in a vehicle, it is desirable that the device appropriately recognizes whether or not the vehicle has departed from a stop. For example, there is a technology that manages the operation information as if the vehicle departed from a stop when detecting the closure of the vehicle door, but there may be a time difference between the door closure timing and the departure timing. Is not accurately reflected.

  The technique described in Patent Document 1 displays a map using a GPS signal, but does not consider managing operation information.

  The present invention has been made in view of the above points, and it is an object of the present invention to provide a technique that supports management of appropriate operation information.

  The present application includes a plurality of means for solving at least a part of the above-described problems. Examples of the means are as follows.

  In order to solve the above problems, an in-vehicle device according to an aspect of the present invention includes a storage unit that stores operation information that is information related to a stop through which a vehicle passes, and an opening / closing detection unit that detects opening and closing of the door of the vehicle. A travel detection unit that detects the start or stop of travel of the vehicle, and the travel detection unit detects the start of travel of the vehicle after the opening / closing detection unit detects the closing of the door, the vehicle is A departure determination unit that determines that the vehicle has started.

  ADVANTAGE OF THE INVENTION According to this invention, the technique which assists management of appropriate operation information can be provided.

  Problems, configurations, and effects other than those described above will be clarified by the following description of embodiments.

It is a figure which shows an example of the data structure of log information. It is a figure which shows the hardware structural example of a vehicle-mounted apparatus.

It is a flowchart which shows an example of the map screen display process of a server apparatus. It is a figure which shows an example of a guidance screen. It is a figure which shows an example of a map screen.

  In the operation of a route bus that sequentially stops at a plurality of stops on a predetermined route, it is important to appropriately grasp the operation status. In particular, by recording the timing of departure from each stop, it is possible to grasp whether proper operation is being performed. Moreover, if the timing which leaves a stop is recognized, the stop which stops next to a driver and a passenger can be guided at a suitable timing.

  Conventionally, when a bus departs from a bus stop, the driver of the route bus inputs the pass button to manage the timing of leaving the bus stop. However, the driver inputs the pass button after the bus departs, that is, during traveling. In particular, when the number of stops on the route is large, it is complicated for the driver to perform an input operation each time.

  In addition to the input of a pass button by the driver, the timing at which the door of the bus is closed may be managed as the bus stop departure timing. This method is preferable in that the driver does not need to perform an input operation for recording the departure timing for each stop. However, for example, when the bus closes the door and waits for a while until the scheduled departure time, and then leaves the stop, if the timing at which the door is closed is recognized as the stop departure timing, the actual departure timing and time lag Occurs.

  In order to avoid the occurrence of this time lag, the driver must open and close the door again immediately before departure, which is troublesome.

  In the present embodiment, door opening / closing, start of travel, and stop of travel of the vehicle are detected, and when the start of travel is detected after detecting the closing of the door, it is determined that the vehicle has left the stop. Thereby, it becomes possible to perform the operation management according to the actual operation status.

  Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an example of functional blocks of the departure determination system 1. The departure determination system 1 includes an in-vehicle device 10 and a server device 20 that are communicably connected via a network n. One or a plurality of in-vehicle devices 10 are connected to the server device 20.

  The in-vehicle device 10 is a computer device mounted on a vehicle. The in-vehicle device 10 may be a part of a navigation device that provides route information to the driver, for example. Hereinafter, an example in which the in-vehicle device 10 is mounted on a bus will be described.

  The bus is a so-called route bus, travels on a predetermined route, and sequentially stops at a plurality of stops installed on the route. It should be noted that the bus may pass without stopping at a stop where neither the customer who gets off nor the customer who gets on.

  The server device 20 is, for example, a server computer, a PC (Personal Computer), or the like, and manages bus operation information including each in-vehicle device 10 based on information transmitted from one or a plurality of in-vehicle devices 10. Further, the server device 20 displays an image showing the bus on the map.

  The in-vehicle device 10 includes a control unit 110, a storage unit 120, an input unit 130, an output unit 140, and a communication unit 150. The control part 110 controls the vehicle-mounted apparatus 10 whole. The storage unit 120 stores information necessary for processing by the control unit 110. The input unit 130 receives input of information to the in-vehicle device 10 through an input device such as a touch panel or a hardware button. The output unit 140 outputs information to an audio output device such as a speaker and a video output device such as a display. The communication unit 150 transmits or receives information to and from the server device 20.

  The control unit 110 includes an open / close detection unit 111, a travel detection unit 112, a departure determination unit 113, a log generation unit 114, and a display information generation unit 115. The open / close detection unit 111 detects the opening and closing of one or more doors of the bus by a door sensor described later. In the present embodiment, when the bus has a plurality of doors, the open / close detection unit 111 treats that the opening of the door is detected when the opening of at least one door is detected, and detects the closing of all the doors. Handled as a detection of door closure.

  The travel detection unit 112 detects the start or stop of the bus travel using a vehicle speed sensor described later. In addition, the travel detection unit 112 specifies the travel distance of the bus. For example, the travel detection unit 112 specifies the travel distance from when the bus starts traveling until the time of measurement.

  The departure determination unit 113 determines whether the bus has left the stop. Specifically, the departure determination unit 113 determines that the bus has departed from the bus stop when the travel detection unit 112 detects the start of bus travel after the opening / closing detection unit 111 detects the closing of the door. The departure determination unit 113 does not determine that the bus has departed from the bus stop even when the stop of travel is detected and the start of travel is detected without detecting the opening of the door.

  In more detail, the departure determination unit 113 detects that the bus has stopped when the travel detection unit 112 detects the start of the bus without detecting the opening of the door after the open / close detection unit 111 detects the door closing. It is determined that the car departed from. Accordingly, even after the door is closed, if the door is opened and the start of traveling is detected without being closed again, the departure determination unit 113 does not determine that the bus has left the stop.

  The log generation unit 114 generates log information including an event type when an event occurs. Events include, for example, door opening, door closing, vehicle running start, vehicle running stop, passing button input reception, and auto-start indicating that the vehicle has been determined to have started. Information that distinguishes events.

  The display information generation unit 115 generates display information of a guidance screen to be displayed on a video output device such as a touch panel. The guidance screen includes the next stop that is the next stop scheduled to stop on the route. The display information generation unit 115 identifies the next stop and displays it on the guidance screen.

  Further, the display information generation unit 115 compares the scheduled departure time of the next stop with the current time, and if the current time is the earlier time, the early departure, and the current time is usually after the scheduled departure time Judgment of departure. The display information generation unit 115 displays different guidance screens for early departures and normal departures.

  The storage unit 120 stores operation information 121 and log information 122. The operation information 121 is information relating to a plurality of stops via the bus, and includes the arrival order of the stops and the scheduled departure time of the stops. The log information 122 is information when an event occurs, and can be said to be information related to the history of the event.

  The server device 20 includes a control unit 210, a storage unit 220, an input unit 230, an output unit 240, and a communication unit 250. The control unit 210 comprehensively controls the entire server device 20. The storage unit 220 stores information necessary for processing by the control unit 210. The input unit 230 receives input of information to the server device 20 via the input device.

  The output unit 240 causes the output device to output information. The output unit 240 outputs a map screen described later via an output device included in the server device 20. The output unit 240 may output the map screen to an administrator terminal (not shown) connected to the server device 20 so as to be communicable. The communication unit 250 transmits or receives information to or from one or a plurality of in-vehicle devices 10.

  The control unit 210 includes a log receiving unit 211, a display position specifying unit 212, and a map screen information generating unit 213. The log receiving unit 211 receives the log information 122 transmitted from the in-vehicle device 10 and stores it in the storage unit 220 as the log information 223.

  The display position specifying unit 212 uses the log information 223 received from the vehicle device to specify at which position on the map the bus image is displayed. When it is determined that the bus has departed from the stop, the display position specifying unit 212 displays an arbitrary position on the route between the departure point and the next stop that is scheduled to stop continuously on the route. The display position of the image showing the bus is specified. In addition, the display position specifying unit 212 specifies the display position so that an image showing the bus is displayed in the vicinity of the next stop when the opening of the door is detected.

  The map screen information generation unit 213 generates screen information of a map screen in which an image showing a bus is superimposed on the map.

  The storage unit 220 stores map information 221, operation information 222, and log information 223. The map information 221 is map information of an area including one or a plurality of bus routes having the in-vehicle device 10 connected to the server device 20. The operation information 222 is information for managing the operation status for each bus having the in-vehicle device 10 connected to the server device 20, and the data structure is the same as that of the operation information 121. The log information 223 is information transmitted from the in-vehicle device 10, and the data structure is the same as the log information 122.

  FIG. 2 is a diagram illustrating an example of the data structure of the operation information 121. The operation information 121 includes a vehicle identifier 121a, a stop identifier 121b, a scheduled departure time 121c, and a passage flag 121d. The vehicle identifier 121a is identification information that identifies a bus. The vehicle-mounted device 10 that the bus has can be specified by the vehicle identifier 122a.

  The stop identifier 121b is identification information that identifies a stop that exists on the route on which the bus is scheduled to travel. The scheduled departure time 121c is information indicating the scheduled departure time of the stop specified by the stop identifier 121b.

  The passage flag 121d is information indicating whether or not the vehicle has passed the stop specified by the stop identifier 121b. The “passing” in this case includes a state where the vehicle leaves after stopping at the stop and a state where the vehicle passes without stopping at the stop. The passage flag 121d is information indicating that “0” has not yet passed, for example, and is information indicating that “1” has passed.

  The operation information 121 includes information indicating the order of arrival at the bus stop. For example, the stop identifier 121b is given a younger number as the arrival order is earlier, and stops having consecutive numbers are scheduled to stop continuously. The operation information 121 shown in FIG. 2 is scheduled to stop in turn at the stop specified by the stop identifier 121b of “001”, “002”, “003”, “004”, and “005”.

  In this figure, “1” of the passage flag 121d is associated with “001”, “002”, “003” of the stop identifier 121b. This is because the stops specified by the stop identifier 121b “001”, “002”, “003” have already passed, and the stops specified by the stop identifier 121b “004”, “005” still pass. Indicates that it is not.

  In the following, a stop that has passed at the newest time among the already passed stops will be described as the next stop, the stop that is next to the previous stop and the previous stop on the route, and that is scheduled to pass next. More specifically, in the operation information 121, among the records that are information indicating that the passage flag 121d has passed, the stop related to the stop identifier 121b of the record with the latest arrival order (arriving later) is the previous stop. Are treated as Further, in the operation information 121, among the records indicating that the passage flag 121d has not yet passed, the stop associated with the stop identifier 121b of the record with the youngest arrival order (arriving first) is the next stop. Are treated as The arrival order of the previous stop and the next stop is continuous in the operation information 121.

  FIG. 3 is a diagram illustrating an example of the data structure of the log information 122. The log information 122 includes a vehicle identifier 122a, a date 122b, a time 122c, and a type 122d. The vehicle identifier 122a is identification information that identifies a bus.

  The date 122b is information indicating the generation date of the record of the log information 122. The time 122c is information indicating the generation time of the record of the log information 122. The type 122d is information for specifying the type of event.

  FIG. 4 is a diagram illustrating a hardware configuration example of the in-vehicle device 10. The in-vehicle device 10 includes an arithmetic processing unit 11.

  The arithmetic processing unit 11 is a central unit in the in-vehicle device 10, and includes a CPU (Central Processing Unit) 12, a RAM (Random Access Memory) 13, a nonvolatile memory 14, and a network I / F (Interface) 15. Each component is connected by a bus.

  The CPU 12 executes processing according to a program stored in the RAM 13 or the nonvolatile memory 14. The RAM 13 is a storage device and functions as a storage area from which programs and data are temporarily read. The non-volatile memory 14 is a non-volatile memory such as a flash memory, and is used as a storage destination for programs and various data. The network I / F 15 is an interface for connecting the in-vehicle device 10 to the network n or an external device.

  In the in-vehicle device 10, processing is performed by the CPU 12 that operates according to a program read out on the RAM 13 or the nonvolatile memory 14. Each processing unit constituting the control unit 110 realizes each function by the CPU 12 executing a program. The function of the storage unit 120 is realized by the RAM 13 or the nonvolatile memory 14. Note that the function of the storage unit 120 may be realized by a storage device on the network n.

  The in-vehicle device 10 is communicably connected to an input device 31, an output device 32, a vehicle speed sensor 33, and a door sensor 34. The input device 31 is a device that receives an input operation from a user, and is a touch panel, a hardware button, or the like, and includes the above-described pass button. The output device 32 is a device that outputs information to the user, including a video output device such as an LCD (Liquid Crystal Display) and an audio output device such as a speaker.

  The vehicle speed sensor 33 is a sensor that detects the vehicle speed of the bus. The vehicle speed sensor 33 detects a vehicle speed pulse signal generated according to, for example, the number of rotations of the tire. For example, the vehicle speed sensor 33 notifies the travel detection unit 112 when it detects a vehicle speed pulse signal. The traveling detection unit 112 measures the number of pulses and treats it as having detected the start of traveling when the number of pulses becomes equal to or greater than a predetermined threshold (for example, 1). Similarly, the travel detection unit 112 detects travel stop and travel distance using the notification from the vehicle speed sensor 33. That is, the travel detection unit 112 realizes its function using the vehicle speed sensor 33.

  Note that the method by which the travel detection unit 112 detects travel conditions such as travel start, travel stop, and travel distance is not limited to a method that uses a vehicle speed pulse signal. For example, the traveling detection unit 112 may detect a traveling state using an image captured using a camera (not shown) connected to the in-vehicle device 10. Hereinafter, the traveling detection unit 112 will be described as detecting a traveling state using a vehicle speed pulse signal.

  The door sensor 34 is a sensor that is installed on one or a plurality of passenger doors of a bus and detects the opening / closing of the door based on the presence / absence of an electrical contact corresponding to the opening / closing of the passenger door. The method in which the door sensor 34 detects opening / closing of the door is not limited to this. For example, an open / closed door may be detected using an infrared sensor or a captured image.

  Note that the door is opened and closed, for example, when an unillustrated electronic control unit (ECU) of the bus detects an input operation to the door opening / closing switch. The opening / closing detection unit 111 may detect the opening / closing of the door by receiving a signal indicating the opening / closing state of the door from the ECU. That is, the opening / closing detection unit 111 realizes its function using the output from the door sensor 34 or the ECU.

  Note that the input device 31, the output device 32, the vehicle speed sensor 33, and the door sensor 34 may be installed in the in-vehicle device 10.

  In addition, the process of each component of the vehicle-mounted apparatus 10 may be performed with one hardware, and may be performed with several hardware. Moreover, the process of each component of the vehicle-mounted apparatus 10 may be implement | achieved by one program, and may be implement | achieved by the some program.

  The server device 20 is realized by a computer having an arithmetic processing unit including a CPU, a RAM, a nonvolatile memory, and a network I / F. The server device 20 is connected to an output device for outputting a map screen.

  FIG. 5 is a flowchart (part 1) illustrating an example of the departure determination process of the in-vehicle device 10. This process is executed by the in-vehicle device 10 while the bus is traveling, for example.

  First, the departure determination unit 113 determines whether or not a pass button has been input (step S11). When the bus passes without stopping at the next stop, it is assumed that a pass button is input. For example, the driver presses the pass button when the passenger does not enter a get-off button for urging to stop at the next stop and there is no customer who gets on from the next stop. When the pass button is pressed, the input unit 130 notifies the departure determination unit 113 of an input to the pass button.

  When the departure determination unit 113 determines that a pass button has been input (in the case of “YES” in step S11), the departure determination unit 113 updates the operation information 121 (step S12). Specifically, the departure determination unit 113 refers to the operation information 121 and associates information indicating that the vehicle has passed with the passage flag 121d of the next stop. In other words, the next stop will be treated as the previous stop.

  Next, the log generation unit 114 generates log information 122 (step S13). Specifically, the log generation unit 114 generates a record of the log information 122 by associating an identifier for identifying the bus with the vehicle identifier 122a, the current date with the date 122b, and the current time with the time 122c. . The log generation unit 114 associates a type indicating the event for which the pass button is input with the type 122d of the generated record. The log generation unit 114 transmits the generated log information 122 to the server device 20.

  Then, the control part 110 returns a process to step S11.

  When the departure determination unit 113 determines that the passing button is not input (in the case of “NO” in step S11), the traveling detection unit 112 determines whether or not the vehicle speed pulse signal is OFF (step S14). ). Specifically, the travel detection unit 112 refers to the vehicle speed pulse signal from the vehicle speed sensor 33 and determines whether or not the bus has stopped traveling. When it is determined that the bus has stopped traveling, the traveling detection unit 112 shifts the process to step S15.

  When traveling detection unit 112 determines that the vehicle speed pulse signal is not OFF (in the case of “NO” in step S14), control unit 110 returns the process to step S11.

  When the traveling detection unit 112 determines that the vehicle speed pulse signal is OFF (“YES” in step S14), the log generation unit 114 generates log information 122 (step S15). Specifically, the log generation unit 114 associates an identifier for identifying the bus with the vehicle identifier 122a, the current date with the date 122b, and the current time with the time 122c. A record of log information 122 that associates the type indicating the canceled event is generated. The log generation unit 114 transmits the generated log information 122 to the server device 20.

  Next, the open / close detection unit 111 determines whether or not the door is opened (step S16). If the bus stops traveling and the door is opened, it is considered that the bus has stopped. In that case, the open / close detection unit 111 moves the process to step S19.

  When the opening / closing detection unit 111 determines that the door is not opened (in the case of “NO” in step S16), the traveling detection unit 112 determines whether or not the vehicle speed pulse signal is ON (step S17). Specifically, the travel detection unit 112 refers to the vehicle speed pulse signal from the vehicle speed sensor 33 and determines whether the bus has started traveling. When the opening / closing detection unit 111 determines that the vehicle speed pulse signal is not ON (“NO” in step S17), the control unit 110 returns the process to step S16.

  When the traveling detection unit 112 determines that the vehicle speed pulse signal is ON (“YES” in step S17), the log generation unit 114 generates log information 122 (step S18). Specifically, the log generation unit 114 associates an identifier for identifying the bus with the vehicle identifier 122a, the current date with the date 122b, and the current time with the time 122c. A record of log information 122 that associates the type indicating the started event is generated. The log generation unit 114 transmits the generated log information 122 to the server device 20. Then, the control part 110 returns a process to step S11.

  In step S14, after the travel detection unit 112 detects the vehicle speed pulse signal OFF, if the opening of the door is not detected in step S16 and the start of travel is detected in step S17, the bus is temporarily stopped by a signal or the like. It is probable that he started running again. In that case, the departure determination unit 113 does not determine that the bus has left the stop.

  When the open / close detection unit 111 determines that the door is opened (“YES” in step S16), the log generation unit 114 generates log information 122 (step S19). Specifically, the log generation unit 114 associates an identifier for identifying the bus with the vehicle identifier 122a, the current date with the date 122b, the current time with the time 122c, and a door with the record type 122d. A record of log information 122 that associates the type indicating the released event is generated. The log generation unit 114 transmits the generated log information 122 to the server device 20.

  Next, the open / close detection unit 111 determines whether or not the door is closed (step S20). When it is determined that the door is not closed (“NO” in step S20), the opening / closing detection unit 111 repeats the process of step S20.

  When the open / close detection unit 111 determines that the door is closed (“YES” in step S20), the log generation unit 114 generates log information 122 (step S21). The log generation unit 114 associates an identifier for identifying the bus with the vehicle identifier 122a, the current date with the date 122b, the current time with the time 122c, and an event with the door closed in the record type 122d. A record of log information 122 that associates the type indicated is generated. The log generation unit 114 transmits the generated log information 122 to the server device 20.

  Next, the display information generation part 115 determines whether it is an early departure (step S22). Specifically, the display information generation unit 115 specifies the next stop with reference to the operation information 121, and specifies the scheduled departure time 121c of the next stop. The display information generation unit 115 compares the specified scheduled departure time 121c with the current time, and determines that the departure is early when the current time is earlier. When the scheduled departure time 121c is the same as the current time or when the scheduled departure time 121c is earlier, the display information generation unit 115 determines that the departure is not early.

  When the display information generation unit 115 determines that it is an early departure (in the case of “YES” in step S22), the display information generation unit 115 performs an early departure display (step S23). The display information generation unit 115 generates screen information of a guidance screen indicating early departure and causes the output device 32 to output the information.

  When the display information generation unit 115 determines that the departure is not early (in the case of “NO” in step S22), the display information generation unit 115 performs normal departure display (step S24). The display information generation unit 115 generates screen information of a guidance screen indicating that the vehicle is normally departing, and causes the output device 32 to output the screen information.

  FIG. 8 is a diagram illustrating an example of the guidance screen 310. FIG. 8A is an example of the guidance screen 310 at the time of early departure, and FIG. 8B is an example of the guidance screen 310 at the time of normal departure. The guidance screen 310 includes a stop display area 311, a next stop instruction display area 312, and a current time display area 313. The guidance screen 310 is displayed to the bus driver and displays information that serves as a guide when the driver drives the bus. The display information generation unit 115 generates display information of the guidance screen 310 using the operation information 121.

  The stop display area 311 displays the next stop, one or a plurality of stops scheduled to stop at the next stop on the route, and the scheduled departure time of each stop. The next stop instruction display area 312 is an area for performing a display instructing the next stop among the stops displayed in the stop display area 311. The current time display area 313 is an area for displaying the current time.

  The display information generation unit 115 displays the early departure guidance screen 310 and the normal departure guidance screen 310 differently in order to call the driver's attention. The guidance screen 310 shown in FIGS. 8A and 8B differs depending on whether the next stop instruction display area 312 displays early departure or normal departure. The display mode is not limited to this. For example, the background color or pattern of the stop display area 311 may be different.

  In the present embodiment, in the case of early departure (the current time is earlier than the scheduled departure time), the driver can respond such as waiting without leaving for a while. Therefore, it is desirable that the early departure guidance screen 310 has a display mode that attracts the driver's eyes more than the normal departure guidance screen 310.

  Returning to FIG. When the early departure display is made in step S23, or when the normal departure display is made in step S24, the traveling detection unit 112 determines whether or not the vehicle speed pulse signal is ON (step S25). The process performed in step S25 is the same as the process performed in step S17. When traveling detection unit 112 determines that the vehicle speed pulse signal is not ON (in the case of “NO” in step S25), it returns the process to step S22. In step S25, when traveling detection unit 112 determines that the vehicle speed pulse signal is ON (in the case of “YES” in step S25), control unit 110 shifts the process to step S26 shown in FIG.

  In other words, when the process in step S25 is executed, the closing of the door is detected in step S20 ("YES" in step S20). That is, the traveling detection unit 112 shifts the process to step S26 when the door is closed and the vehicle speed pulse signal is ON. In other words, the travel detection unit 112 causes the process to proceed to step S26 when the opening of the door is detected without detecting the opening of the door after the door is detected to be closed.

  In addition, when the opening / closing detection unit 111 detects the opening of the door after detecting the closing of the door in step S20, the control unit 110 performs processing after the log generation unit 114 generates the log information 122 indicating the door opening. To step S20. That is, the open / close detection unit 111 determines whether or not the opened door is closed. Even if the bus departs with the door open, the processing after step S21 is not performed and it is not determined that the bus departs.

  FIG. 6 is a flowchart (part 2) illustrating an example of the departure determination process of the in-vehicle device 10. Since the process performed in step S26 is the same as the process performed in step S18, description is abbreviate | omitted.

  The processing performed from step S27 to step S29 is the same as the processing performed from step S22 to step S24, and thus the description thereof is omitted.

  Next, the traveling detection unit 112 determines whether or not the vehicle has traveled a predetermined distance (step S30). Specifically, the travel detection unit 112 refers to the vehicle speed pulse signal acquired by the vehicle speed sensor 33, and acquires the travel distance from the start of travel in step S25 to the present. The travel detection unit 112 refers to a predetermined distance stored in an area (not shown) of the storage unit 120 and determines whether or not the vehicle has traveled a distance greater than or equal to a predetermined distance.

  When traveling detection unit 112 determines that the vehicle has not traveled the predetermined distance (when “NO” in step S30), traveling detection unit 112 returns the process to step S27. That is, in step S20, when the door is detected to be closed, and in step S25, the start of the bus is detected, as long as the bus does not travel a predetermined distance or more, the bus leaves the stop. Is not determined.

  When a bus departs from a bus stop and a customer who wants to get on the bus travels a little and displays an intention to board the bus, for example, the bus may stop again and get on the customer. Thus, even if the bus stops at the same stop a plurality of times, if it is determined that the bus has departed from the next stop, bus operation management is not performed appropriately. Therefore, the in-vehicle device 10 stores the predetermined distance, and determines that the next stop is departed when the vehicle starts traveling after a predetermined distance after the start of the bus is detected after the door is closed.

  In step S30, when the travel detection unit 112 determines that the vehicle has not traveled the predetermined distance, the vehicle speed pulse signal is subsequently turned off, the opening / closing of the door is detected, and then the vehicle speed pulse signal is turned on. , Log information 122 corresponding to each event is generated and transmitted to the server device 20. Thereafter, when it is determined that the bus has traveled a predetermined distance, the travel detection unit 112 shifts the processing to step S31.

  In other words, if it is not assumed that the bus stops at the same stop a plurality of times, the process of step S30 can be omitted.

  When the travel detection unit 112 determines that the vehicle has traveled the predetermined distance (when “YES” in step S30), the departure determination unit 113 determines that the bus has left the stop (step S31). That is, as in step S12, the departure determination unit 113 refers to the operation information 121 and associates information indicating that the vehicle has passed with the passing flag 121d of the next stop. In other words, the next stop is treated as the previous stop.

  Next, the log generation unit 114 generates log information 122 (step S32). The log generation unit 114 associates an identifier for identifying the bus with the vehicle identifier 122a, the current date with the date 122b, the current time with the time 122c, and the event type indicating auto-start with the record type 122d. Is generated as a record of log information 122 associated with. The log generation unit 114 transmits the generated log information 122 to the server device 20.

  Next, the display information generation unit 115 deletes the guidance screen (step S33). Specifically, the display information generation unit 115 stops displaying the guidance information displayed in step S28 or step S29. Then, the control part 110 returns a process to step 11 of FIG.

  In this embodiment, the guidance screen is displayed after the door is closed, and the guidance screen is stopped after the departure determination. However, the display period of the guidance screen is not limited to this. For example, the display information generation unit 115 may periodically perform the processing from step S22 to step S24 to display a constant guidance screen.

  As described above, the guidance screen 310 is screen information displayed to the driver. However, a display screen for notifying the customer of the next stop may be displayed in relation to the display of the guidance screen 310. . In this case, for example, the display information generation unit 115 generates display information of a notification screen indicating the next stop, and outputs a notification screen to a video output device visible to the customer via the output unit 140. The output unit 140 may generate audio information for notifying the customer of the next stop and output the audio information to an audio output device such as a speaker.

  In other words, when it is desired to provide a time difference between the input of the passing button or the determination that the bus has departed from the bus stop and the display of the guidance screen or the notification screen, a threshold for the travel distance may be provided. Specifically, the display information generation unit 115 acquires the travel distance of the bus after the pass button is input or the departure of the bus is determined via the travel detection unit 112, and the travel distance exceeds a threshold value. In addition, a guidance screen or a notification screen may be displayed.

  In the present embodiment, it is determined whether or not the bus has departed using the vehicle speed pulse signal and information indicating opening / closing of the door. Thereby, the timing at which the bus leaves the bus stop can be appropriately managed. In addition, more accurate operation management is possible as compared with the embodiment in which closing of the door is regarded as the departure timing of the stop.

  FIG. 7 is a flowchart illustrating an example of the map screen display process of the server device 20. This process is periodically executed in the server device 20, for example. When the log receiving unit 211 receives the log information 122 from the in-vehicle device 10, the log receiving unit 211 stores the log information 223 in the storage unit 220. In the following, description will be made using an example in which “A” is the previous stop, “B” is the next stop, and “C” is the “next stop” scheduled to stop at the next stop.

  First, the log receiving unit 211 determines whether or not a pass button log has been received (step S41). Specifically, the log reception unit 211 refers to the type of the log information 223 received from the in-vehicle device 10 and determines that the pass button log has been received when the information indicates the input of the pass button.

  When the log reception unit 211 determines that the passing button log has not been received (in the case of “NO” in step S41), the log reception unit 211 determines whether or not a vehicle speed pulse OFF log has been received (step S41). S42). Specifically, the log receiving unit 211 refers to the type of the log information 223 received from the in-vehicle device 10 and determines that the vehicle speed pulse OFF log has been received when the information is information indicating that the traveling has been stopped.

  When the log reception unit 211 determines that the vehicle speed pulse OFF log has not been received (in the case of “NO” in step S42), the log reception unit 211 returns the process to step S41.

  When it is determined that the log reception unit 211 has received the vehicle speed pulse OFF log ("YES" in step S42), the log reception unit 211 determines whether the door opening log or the vehicle speed pulse ON log has been received. (Step S43). Specifically, the log reception unit 211 refers to the type of the log information 223 received from the in-vehicle device 10 and determines whether the information is information indicating the opening of the door or the information indicating the start of traveling. If neither type of log information 223 has been received, the log reception unit 211 repeats the process of step S43 until either type of log information 223 is received.

  When the log reception unit 211 determines that the vehicle speed pulse ON log has been received (in the case of “vehicle speed pulse ON log” in step S43), the log reception unit 211 returns the process to step S41.

  When the log receiving unit 211 determines that the door opening log has been received (in the case of “door opening log” in step S43), the display position specifying unit 212 specifies the next stop as the bus position (step S44). When the opening of the door is detected, the server device 20 treats the bus as having arrived at the next stop. Specifically, the display position specifying unit 212 specifies the bus using the vehicle identifier included in the log information 223, extracts the record of the operation information 222 related to the specified bus, and sets the passing flag of the extracted record. Identify the next stop by referring to it.

  The display position specifying unit 212 specifies a position in the vicinity of the next stop (a predetermined distance from the next stop) in the map information 221 as a display position of a bus image that is an image showing a bus. The display position specifying unit 212 may specify the display position so that the image of the next stop and the bus image are superimposed.

  Next, the map screen information generation unit 213 arranges and displays the bus image at the bus position (step S45). Specifically, the map screen information generation unit 213 uses the map information 221 to generate screen information of a map screen in which a bus image is arranged at the bus position specified in step S44. The map screen information generation unit 213 causes the output unit 240 to output a map screen using the generated screen information.

  FIG. 9 is a diagram illustrating an example of the map screen 320. The map screen 320 includes a stop image 321 and a bus image 322. FIG. 9 shows a stop image 321A indicating “A” as the previous stop, a stop image 321B indicating “B” as the next stop, and “C” as the next stop as the stop image 321. A stop image 321C is displayed.

  In this example, since the next stop is “B”, the display position specifying unit 212 specifies the bus position in the vicinity of the stop image 321B. The map screen information generation unit 213 displays a map screen 320 in which the bus image 322 is arranged in the vicinity of the stop image 321B.

  Returning to FIG. Next, the log receiving unit 211 determines whether or not the auto start log information 223 has been received (step S46). Specifically, the log reception unit 211 refers to the type of the log information 223 received from the in-vehicle device 10 and determines that the auto start log is received when the information indicates the auto start. When it is determined that the log reception unit 211 has not received the auto start log (in the case of “NO” in step S46), the log reception unit 211 repeats the process of this step until the auto start log is received. .

  In this step, the log receiving unit 211 determines whether or not it has received the door closing log information 223 and the vehicle speed pulse ON log information 223 instead of determining whether or not the auto start log information 223 has been received. May be determined. That is, the log reception unit 211 refers to the type of the log information 223 received from the in-vehicle device 10 and receives the log information 223 including information indicating the start of travel after receiving the log information 223 indicating information indicating door closing. In such a case, the process may be advanced to step 47.

  When it is determined that the log reception unit 211 has received the auto-start log (“YES” in step S46), the log reception unit 211 updates the operation information 222 (step S47). After receiving the door closing log, when the travel start log is received, the departure determination unit 113 of the in-vehicle device 10 determines that the bus has left the stop, but the bus has also started at the server device 20. Treated with things. Specifically, the log reception unit 211 refers to the operation information 222 and associates information indicating that the vehicle has passed with the passing flag of the next stop. That is, the next stop is treated as the previous stop.

  As a result, the previous stop becomes “B” and the next stop becomes “C”.

  Next, the display position specifying unit 212 specifies the bus position between the previous stop and the next stop (step S48). Specifically, the display position specifying unit 212 is configured to select an arbitrary route on the route between the departure stop (previous stop) and the stop (next stop) scheduled to stop at the previous stop in the operation information 222. The position is specified as the bus position.

  In the map screen 320 in FIG. 9, the stop image 321 of the previous stop becomes the stop image 321B, and the stop image 321 of the next stop becomes the next stop image 321C. Therefore, the display position specifying unit 212 specifies an arbitrary position on the route between the stop image 321B and the stop image 321C as the bus position. Note that the bus position may be set to a position where it can be recognized that the bus has left the previous stop. For example, the bus position is an intermediate place on the route between the previous stop image and the next stop image.

  Returning to FIG. Since the process performed in step S49 is the same as the process performed in step S45, description thereof is omitted. Then, the control part 210 returns a process to step S41.

  In step S41, when the log reception unit 211 determines that the pass button log has been received (in the case of “YES” in step S41), the log reception unit 211 updates the operation information 222 (step S51). Specifically, the log reception unit 211 refers to the operation information 222 and associates information indicating that the vehicle has passed with the passing flag of the next stop.

  Since the processing performed from step S52 to step S53 is the same as the processing performed from step S48 to step S49, description thereof is omitted. Then, the control part 210 returns a process to step S41.

  According to the present embodiment, the position of the bus can be displayed efficiently. In particular, when it is detected that the bus has started running after the bus door is closed, the bus is handled as having left the stop, and a display indicating that the bus has departed is displayed. Therefore, more accurate display can be performed without taking measures such as opening the door immediately before departure.

  Note that the display may be different depending on whether the bus departs from the bus stop and is traveling or is stopped at the bus stop. For example, since the door opening log is received at step 43 in FIG. 7 and the vehicle speed pulse ON log is received at step S47, the vehicle is stopped at the stop. It may be displayed differently from the case.
