Information on the operation of the vehicle, including the stop at the bus stop or the departure from the bus stop, is acquired in the vehicle and used for the management of the operation information. When acquiring information on operation in a vehicle, it is desirable that the device appropriately recognizes whether or not the vehicle has departed from the bus stop. For example, there is a technology to manage operation information as if the vehicle departed from the bus stop when the door of the vehicle was closed, but there may be a time lag between the timing of closing the door and the timing of departure, and the operation status. Is not exactly reflected.

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

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

The present application includes a plurality of means for solving at least a part of the above problems, and examples thereof are as follows.

In order to solve the above problems, the in-vehicle device according to one aspect of the present invention includes a storage unit that stores operation information that is information about a stop via a vehicle, and an open / close detection unit that detects the opening / closing of a door of the vehicle. When the travel detection unit detects the start or stop of travel of the vehicle and the open / close detection unit detects the closing of the door, the travel detection unit detects the start of travel of the vehicle, and the vehicle stops. The departure determination unit includes a departure determination unit that determines that the vehicle has departed from the vehicle, and the departure determination unit does not detect the opening of the door after the travel detection unit detects that the vehicle has stopped traveling. When the travel detection unit detects the start of travel of the vehicle, it is characterized in that it does not determine that the vehicle has departed from the stop .

According to the present invention, it is possible to provide a technique for supporting the management of appropriate operation information.

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

It is a flowchart which shows an example of the map screen display processing of a server device. 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 fixed-route bus that stops sequentially at multiple stops on a predetermined route, it is important to properly grasp the operation status. In particular, by recording the timing of departure from each bus stop, it is possible to grasp whether proper operation is being performed. Further, if the timing of departure from the bus stop is recognized, the driver and passengers can be guided to the next bus stop at a suitable timing.

Conventionally, when a bus driver departs from a bus stop, the driver of the route bus inputs a passing button to manage the timing of departure from the bus stop. However, the driver will input the pass button after the bus departs, that is, while the bus is running. 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 the pass button by the driver, the timing at which the door of the bus is closed may be managed as the departure timing of the bus stop. This method is preferable in that the driver does not need to perform an input operation for recording the departure timing at each stop. However, for example, if the bus closes the door, waits for a while until the scheduled departure time, and then departs from the bus stop, if the timing when the door is closed is recognized as the departure timing of the bus stop, 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, it is determined that the vehicle has departed from the bus stop when the door opening / closing, running start, and running stop of the vehicle are detected, and when the running start is detected after the door closure is detected. This makes it possible to manage the operation according to the actual operation situation.

Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an example of a functional block 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 the network n. One or a plurality of vehicle-mounted 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 the bus will be described.

A bus is a so-called fixed-route bus, which travels on a predetermined route and sequentially stops at a plurality of stops installed on the route. Buses may pass through without stopping at stops where there are no customers getting off or getting on.

The server device 20 is, for example, a server computer, a PC (Personal Computer), or the like, and manages operation information of a bus having each in-vehicle device 10 based on information transmitted from one or more 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 unit 110 comprehensively controls the entire vehicle-mounted device 10. 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 via 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 a plurality of doors of the bus by the door sensor described later. In the present embodiment, when the bus has a plurality of doors, the open / close detection unit 111 treats it as detecting the opening of at least one door when it detects the opening of the door, and detects the closing of all the doors. Treat as a door closure detected.

The travel detection unit 112 detects the start or stop of travel of the bus by using the vehicle speed sensor described later. Further, the travel detection unit 112 specifies the travel distance of the bus. For example, the travel detection unit 112 specifies the travel distance from the start of travel of the bus to the time of measurement.

The departure determination unit 113 determines whether or not the bus has departed from the bus 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 travel of the bus after the open / close detection unit 111 detects that the door is closed. The departure determination unit 113 does not determine that the bus has departed from the bus stop if the start of travel is detected without detecting the opening of the door, even when the stop of travel is detected.

More specifically, when the departure determination unit 113 detects that the door is closed and then the travel detection unit 112 detects the start of travel of the bus without detecting the opening of the door, the bus stops. It is determined that the train departed from. Therefore, even after the door is closed, if the door is opened and the start of traveling is detected without closing again, the departure determination unit 113 does not determine that the bus has departed from the bus stop.

When an event occurs, the log generation unit 114 generates log information including the type of the event. The event is, for example, opening the door, closing the door, starting the running of the vehicle, stopping the running of the vehicle, accepting the input of the passing button, and auto-start indicating that the vehicle has been determined to depart. 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, which is the next stop on the route. The display information generation unit 115 identifies the next stop and displays it on the guidance screen.

In addition, the display information generation unit 115 compares the scheduled departure time of the next stop with the current time, and when the current time is earlier than the scheduled departure time, the departure is early, and when the current time is after the scheduled departure time, it is normal. Judged as departure. The display information generation unit 115 displays the guidance screen differently between the case of early departure and the case of normal departure.

The storage unit 120 stores the operation information 121 and the log information 122. The operation information 121 is information about a plurality of stops via a bus, and includes an arrival order of the stops and a scheduled departure time of the stops. The log information 122 is information when an event occurs, and can be said to be information regarding 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 the map screen described later via the 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 vehicle-mounted devices 10.

The control unit 210 includes a log reception unit 211, a display position specifying unit 212, and a map screen information generation unit 213. The log receiving unit 211 receives the log information 122 transmitted from the vehicle-mounted 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 image showing the bus is displayed. When it is determined that the bus departs from the stop, the display position specifying unit 212 determines an arbitrary position on the route between the departed stop and the next stop scheduled to continuously stop at the stop on the route. , Specify the display position of the image showing the bus. Further, the display position specifying unit 212 specifies the display position so as to display an image showing the bus 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 a 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 a route of one or a plurality of buses having an 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 vehicle-mounted device 10, and has the same data structure as the log information 122.

FIG. 2 is a diagram showing 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 passing flag 121d. The vehicle identifier 121a is identification information for identifying the bus. The vehicle-mounted device 10 of the bus can be identified by the vehicle identifier 122a.

The stop identifier 121b is identification information that identifies a stop existing 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 bus stop specified by the bus stop identifier 121b.

The passage flag 121d is information indicating whether or not the bus has passed the stop specified by the stop identifier 121b. The "passing" in this case includes a state in which the vehicle departs after stopping at the bus stop and a state in which the vehicle passes through without stopping at the bus stop. The passage flag 121d is, for example, information indicating that "0" has not yet passed, 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 assigned a lower number as the arrival order is earlier, and the stops having consecutive numbers are scheduled to stop consecutively. The operation information 121 shown in FIG. 2 is scheduled to stop in order at a bus stop whose stop identifier 121b is specified by each of "001", "002", "003", "004", and "005".

In this figure, the passage flag 121d "1" is associated with the stop identifier 121b "001", "002", and "003". This is because the stop specified by "001", "002", "003" of the stop identifier 121b has already passed, and the stop specified by "004", "005" of the stop identifier 121b has still passed. It shows that it is not.

Hereinafter, the bus that has passed at the latest time among the stops that have already passed will be described as the previous stop, the previous stop on the route, and the stop that is scheduled to pass next will be described as the next stop. More specifically, in the operation information 121, among the records indicating that the passing flag 121d has passed, the stop related to the stop identifier 121b of the record having the latest arrival order (arriving last) is the previous stop. Treated as. Further, in the operation information 121, among the records indicating that the passage flag 121d has not yet passed, the stop related to the stop identifier 121b of the record having the youngest arrival order (arriving first) is the next stop. 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 showing 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 for identifying the 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 the event.

FIG. 4 is a diagram showing 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 non-volatile memory 14, and a network I / F (Interface) 15. Each component is connected by a bus.

The CPU 12 executes the process according to the program stored in the RAM 13 or the non-volatile memory 14. The RAM 13 is a storage device and functions as a storage area where programs and data are temporarily read out. 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 / F15 is an interface for connecting the vehicle-mounted 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 the program read out on the RAM 13 or the non-volatile memory 14. Each processing unit constituting the control unit 110 realizes each function by executing a program by the CPU 12. Further, the function of the storage unit 120 is realized by the RAM 13 or the non-volatile memory 14. 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 the input device 31, the output device 32, the vehicle speed sensor 33, and the door sensor 34. The input device 31 is a device that receives an input operation from the user, is a touch panel, a hardware button, or the like, and includes the above-mentioned 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, for example, a vehicle speed pulse signal generated according to the rotation speed of the tire. For example, when the vehicle speed sensor 33 detects a vehicle speed pulse signal, it notifies the travel detection unit 112. The travel detection unit 112 measures the number of pulses, and treats it as detecting the start of travel when the number of pulses reaches a predetermined threshold value (for example, 1) or more. Similarly, the travel detection unit 112 detects the travel stop and the travel distance by using the notification from the vehicle speed sensor 33. That is, the travel detection unit 112 realizes its function by using the vehicle speed sensor 33.

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

The door sensor 34 is a sensor that is installed in one or more doors of a bus and detects the opening / closing of the door depending on the presence / absence of an electric contact corresponding to the opening / closing of the door. The method by which the door sensor 34 detects the opening / closing of the door is not limited to this. For example, an infrared sensor or a photographed image may be used to detect the opening and closing of the door.

The opening and closing of the door is executed, for example, by detecting an input operation to the door opening / closing switch by an electronic control unit (ECU) of the bus (not shown). The open / close detection unit 111 may detect the open / closed of the door by receiving a signal indicating the open / closed state of the door from the ECU. That is, the open / close detection unit 111 realizes its function by using the output from the door sensor 34 or the ECU.

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.

The processing of each component of the vehicle-mounted device 10 may be executed by one hardware or may be executed by a plurality of hardware. Further, the processing of each component of the in-vehicle device 10 may be realized by one program or may be realized by a plurality of programs.

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

FIG. 5 is a flowchart (No. 1) showing 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 running, for example.

First, the departure determination unit 113 determines whether or not the passage button has been input (step S11). It is assumed that the pass button will be entered when the bus passes without stopping at the next stop. For example, when the passenger does not input the disembarkation button prompting to stop at the next stop and there is no customer to board from the next stop, the driver presses the pass button. When the pass button is pressed, the input unit 130 notifies the departure determination unit 113 of the input to the pass button.

When the departure determination unit 113 determines that the passing button has been input (when "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 the passage flag 121d of the next stop with information indicating that the vehicle has passed. That is, 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 log information 122 by associating the vehicle identifier 122a with the identifier that identifies the bus, the date 122b with the current date, and the time 122c with the current time. .. The log generation unit 114 associates the generated record type 122d with the type indicating the event in which the pass button is input. The log generation unit 114 transmits the generated log information 122 to the server device 20.

After that, the control unit 110 returns the process to step S11.

When the departure determination unit 113 determines that the pass button has not been input (when "NO" in step S11), the travel 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 the travel detection unit 112 determines that the bus has stopped traveling, the travel detection unit 112 shifts the process to step S15.

When the travel detection unit 112 determines that the vehicle speed pulse signal is not OFF (when "NO" in step S14), the control unit 110 returns the process to step S11.

When the travel detection unit 112 determines that the vehicle speed pulse signal is OFF (when "YES" in step S14), the log generation unit 114 generates log information 122 (step S15). Specifically, the log generation unit 114 associates the vehicle identifier 122a with the identifier that identifies the bus, the date 122b with the current date, and the time 122c with the current time, and sets the record type 122d to travel. Generates a record of log information 122 associated with the type indicating the canceled event. 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 has been opened (step S16). If the bus stops running and the door is opened, it is considered that the bus has stopped at the bus stop. In that case, the open / close detection unit 111 shifts the process to step S19.

When the open / close detection unit 111 determines that the door is not opened (“NO” in step S16), the travel 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 or not the bus has started traveling. When the open / close detection unit 111 determines that the vehicle speed pulse signal is not ON (when "NO" in step S17), the control unit 110 returns the process to step S16.

When the travel detection unit 112 determines that the vehicle speed pulse signal is ON (when "YES" in step S17), the log generation unit 114 generates log information 122 (step S18). Specifically, the log generation unit 114 associates the vehicle identifier 122a with the identifier that identifies the bus, the date 122b with the current date, and the time 122c with the current time, and sets the record type 122d to travel. Generates a record of log information 122 associated with the type indicating the started event. The log generation unit 114 transmits the generated log information 122 to the server device 20. After that, the control unit 110 returns the process to step S11.

If the travel detection unit 112 detects that the vehicle speed pulse signal is OFF in step S14, then the door opening is not detected in step S16 and the travel start is detected in step S17, the bus temporarily stops due to a signal or the like. It is probable that the car started running again. In that case, the departure determination unit 113 does not determine that the bus has departed from the bus stop.

When the open / close detection unit 111 determines that the door has been opened (when “YES” in step S16), the log generation unit 114 generates log information 122 (step S19). Specifically, the log generation unit 114 associates the vehicle identifier 122a with the identifier that identifies the bus, the date 122b with the current date, the time 122c with the current time, and the record type 122d with a door. Generates a record of log information 122 associated with the type indicating the released event. 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 the open / close detection unit 111 determines that the door is not closed (when "NO" in step S20), the open / close detection unit 111 repeats the process of step S20.

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

Next, the display information generation unit 115 determines whether or not the vehicle departs early (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. If the scheduled departure time 121c and the current time are the same, or 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 the vehicle departs early (when "YES" in step S22), the display information generation unit 115 displays the early departure (step S23). The display information generation unit 115 generates screen information on the guidance screen indicating that the vehicle departs early, and outputs the screen information to the output device 32.

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

FIG. 8 is a diagram showing an example of the guide 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 has 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 driver of the bus, and information that serves as a guide for the driver to drive the bus is displayed. The display information generation unit 115 generates the display information of the guidance screen 310 using the operation information 121.

In the stop display area 311, the next stop, one or more stops scheduled to be continuously stopped at the next stop on the route, and the scheduled departure time of each stop are displayed. The next stop instruction display area 312 is an area among the stops displayed in the stop display area 311 that displays an instruction to indicate the next stop. 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 draw the driver's attention. In the guidance screen 310 shown in FIGS. 8A and 8B, the display of the next stop instruction display area 312 is different between the case of early departure and the case of 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, the driver can take measures such as waiting without departing for a while in the case of early departure (the current time is earlier than the scheduled departure time). Therefore, it is desirable that the early departure guidance screen 310 has a display mode that is more eye-catching to the driver than the normal departure guidance screen 310.

The explanation is returned to FIG. When the early departure display is made in step S23, or when the normal departure display is made in step S24, the travel 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 the travel detection unit 112 determines that the vehicle speed pulse signal is not ON (when "NO" in step S25), the process returns to step S22. In step S25, when the travel detection unit 112 determines that the vehicle speed pulse signal is ON (when “YES” in step S25), the control unit 110 shifts the process to step S26 shown in FIG.

In addition, when the process in step S25 is executed, the closing of the door is detected in step S20 (“YES” in step S20). That is, when the door is closed and the vehicle speed pulse signal is ON, the travel detection unit 112 shifts the process to step S26. In other words, the travel detection unit 112 shifts the process to step S26 when the travel detection unit 112 detects the start of travel of the bus without detecting the opening of the door after the closure of the door is detected.

If the open / close detection unit 111 detects that the door is closed in step S20 and then detects that the door is open again, the log generation unit 114 generates log information 122 indicating that the door is open, and then the control unit 110 processes it. 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 has departed.

FIG. 6 is a flowchart (No. 2) showing 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, the description thereof will be omitted.

Since the processing performed in steps S27 to S29 is the same as the processing performed in steps S22 to S24, the description thereof will be omitted.

Next, the travel 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 detection of the start of travel to the present in step S25. 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 the predetermined distance.

When the travel detection unit 112 determines that the vehicle has not traveled a predetermined distance (when “NO” in step S30), the travel detection unit 112 returns the process to step S27. That is, even if the closing of the door is detected in step S20 and the start of the bus is detected in step S25, the bus departs from the bus stop unless the bus travels a predetermined distance or more. Is not determined.

When a customer who wants to get on a bus departs from a bus stop and runs a little, the bus may stop again and get the customer on board. In this way, even if the bus stops at the same stop multiple times, if it is determined that the bus has departed from the next stop, the bus operation management will not be performed properly. Therefore, the in-vehicle device 10 stores a predetermined distance, and when the bus travels for a predetermined distance after the start of travel of the bus is detected after the door is closed, it is determined that the bus has departed from the next stop.

In step S30, when it is determined that the travel detection unit 112 has not traveled a predetermined distance, the vehicle speed pulse signal is subsequently turned off, the opening and 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. After that, when it is determined that the bus has traveled a predetermined distance, the travel detection unit 112 shifts the process to step S31.

In addition, if it is not expected that the bus will stop at the same stop multiple times, the process of step S30 can be omitted.

When the travel detection unit 112 determines that the bus has traveled a predetermined distance (when "YES" in step S30), the departure determination unit 113 determines that the bus has departed from the bus stop (step S31). That is, as in step S12, the departure determination unit 113 refers to the operation information 121 and associates the passage flag 121d of the next stop with the information indicating that the vehicle has passed. 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 the vehicle identifier 122a with the identifier that identifies the bus, the date 122b with the current date, the time 122c with the current time, and the record type 122d with the event type indicating autostart. Generates 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 erases the guidance screen (step S33). Specifically, the display information generation unit 115 stops displaying the guidance information displayed in step S28 or step S29. After that, the control unit 110 returns the process to step 11 in FIG.

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

Further, as described above, the guidance screen 310 is screen information displayed to the driver, but a display screen notifying the customer of the next stop may be displayed in connection with the display of the guidance screen 310. .. In this case, for example, the display information generation unit 115 generates the display information of the notification screen indicating the next stop, and causes the video output device visible to the customer to output the notification screen via the output unit 140. Further, the output unit 140 may generate voice information for notifying the customer of the next stop and output it to a voice output device such as a speaker.

In addition, if 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 stop and the display of the guidance screen or the notification screen, a threshold value for the mileage may be set. Specifically, when the display information generation unit 115 acquires the mileage of the bus after the passage button is input or the departure determination of the bus is made via the travel detection unit 112, and the mileage exceeds the 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 from the bus stop by using the vehicle speed pulse signal and the information indicating the opening / closing of the door. This makes it possible to appropriately manage the timing at which the bus departs from the bus stop. In addition, more accurate operation management becomes possible as compared with the embodiment in which the closing of the door is regarded as the departure timing of the bus stop.

FIG. 7 is a flowchart showing an example of the map screen display process of the server device 20. This process is executed, for example, periodically in the server device 20. When the log receiving unit 211 receives the log information 122 from the in-vehicle device 10, it is stored in the storage unit 220 as the log information 223. Hereinafter, an example will be described in which the previous stop is "A", the next stop is "B", and the "next next stop" scheduled to stop continuously at the next stop is "C".

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

When the log receiving unit 211 determines that the passing button log has not been received (when "NO" in step S41), the log receiving unit 211 determines whether or not the vehicle speed pulse OFF log has been received (step). S42). Specifically, the log receiving unit 211 refers to the type of 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 indicates that the vehicle has stopped traveling.

When the log receiving unit 211 determines that the vehicle speed pulse OFF log has not been received (when "NO" in step S42), the log receiving unit 211 returns the process to step S41.

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

When the log receiving 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 receiving 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 the "door opening log" in step S43), the display position specifying unit 212 specifies the next stop at 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 identifies 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 reference.

The display position specifying unit 212 specifies the position in the vicinity of the next stop (predetermined distance from the next stop) in the map information 221 as the display position of the bus image which is an image showing the 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 on the map screen in which the 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 the map screen using the generated screen information.

FIG. 9 is a diagram showing an example of the map screen 320. The map screen 320 includes a stop image 321 and a bus image 322. FIG. 9 shows the stop image 321A showing the previous stop “A”, the stop image 321B showing the next stop “B”, and the next stop “C” as the stop image 321. The bus stop image 321C and 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 the map screen 320 in which the bus image 322 is arranged in the vicinity of the stop image 321B.

The explanation is returned 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 receiving 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 has been received when the information indicates the auto start. When the log receiving unit 211 determines that the auto start log has not been received (when "NO" in step S46), the log receiving unit 211 repeats the process of this step until the auto start log is received. ..

In this step, the log receiving unit 211 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 receiving unit 211 refers to the type of log information 223 received from the in-vehicle device 10, receives the log information 223 which is information indicating the door closure, and then receives the log information 223 including the type indicating the start of traveling. If so, the process may proceed to step 47.

When the log reception unit 211 determines that the auto start log has been received (when "YES" in step S46), the log reception unit 211 updates the operation information 222 (step S47). When the log of the start of traveling is received after the log of the door closure is received, the departure determination unit 113 of the in-vehicle device 10 determines that the bus has departed from the bus stop, but the server device 20 also departs the bus from the bus stop. Treated as a thing. Specifically, the log reception unit 211 refers to the operation information 222 and associates information indicating that the bus has passed with the passage 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 an arbitrary bus stop on the route between the bus stop (previous bus stop) where the bus departed and the bus stop (next bus stop) scheduled to continuously stop at the previous bus stop in the operation information 222. Specify the position to the bus position.

In the map screen 320 in FIG. 9, the stop image 321 of the previous stop became the stop image 321B, and the stop image 321 of the next stop became 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 a bus position. The bus position may be set to a position where it can be recognized that the bus has departed from the previous stop. For example, the bus position is an intermediate point on the route between the previous stop image and the next stop image.

The explanation is returned to FIG. Since the process performed in step S49 is the same as the process performed in step S45, the description thereof will be omitted. After that, the control unit 210 returns the process to step S41.

When it is determined in step S41 that the log receiving unit 211 has received the pass button log (when "YES" in step S41), the log receiving 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 bus has passed with the passage flag of the next stop.

Since the processing performed in steps S52 to S53 is the same as the processing performed in steps S48 to S49, the description thereof will be omitted. After that, the control unit 210 returns the process to step S41.

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

The display may be different depending on whether the bus departs from the bus stop and is running, or is stopped at the bus stop. For example, since the vehicle is stopped at the stop until the door opening log is received in step 43 of FIG. 7 and the vehicle speed pulse ON log is received in step S47, the colors of the bus image 322 and the like are different during this period. It may be displayed differently from the case.
