[0013] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0014] As shown in FIG. 1, an information presentation system 100 according to an embodiment is a system capable of presenting information relating to the idling time of a vehicle 1. The information presentation system 100 includes a digital tachograph 10, a digital tachograph server 20, and an administrator PC (personal computer) 40. The digital tachograph 10 is an example of an on-board device mounted on the vehicle 1. The digital tachograph server 20 is an example of an information presentation device capable of communicating with the digital tachograph 10. The administrator PC 40 is an example of a communication terminal capable of communicating with the digital tachograph server 20.

[0015] The digital tachograph 10 is mounted on a vehicle 1 such as a truck, collects operation information (so-called digital tachograph data) including the driving state of the vehicle 1, and is used to create a daily report based on, for example, a day's worth of operation information. Specifically, the digital tachograph 10 is a driving recorder that records the driving speed, driving time, driving distance, etc. of the vehicle 1. The digital tachograph 10 can be wirelessly connected to a network N such as the Internet via a base station B, for example, by wireless communication. The digital tachograph 10 is sometimes simply called a "digital tachograph 10."

[0016] The digital tachograph server 20 is a computer device capable of communicating with the digital tachograph 10 via the network N, and exchanging operation information of the vehicle 1 with the digital tachograph 10. The digital tachograph server 20 is installed, for example, at a service provider that provides an analysis service of digital tachograph data, but may also be installed at a business (for example, a transport company) that operates the vehicle 1.

[0017] The administrator PC 40 is a communication terminal used by a vehicle manager of the business that operates the vehicle 1, and is capable of communicating with at least one of the digital tachograph 10 and the digital tachograph server 20, and in this embodiment, both, via the network N. The communication terminal is not limited to a fixed type such as the administrator PC 40, but may be a portable device such as a tablet, smartphone, or mobile phone.

[0018] In recent years, with the growing interest in environmental issues, businesses that handle vehicles have started to acquire information to determine whether or not a vehicle is idling, and to use this information to improve the driver's work, in order to reduce the unnecessary idling time of the vehicle. In this embodiment, a digital tachograph 10 mounted on a vehicle 1 collects information on whether or not the vehicle is idling, and transmits it to a digital tachograph server 20. This allows the digital tachograph server 20 to acquire and present specific information on idling time. By presenting specific information on idling time, it becomes possible to provide appropriate guidance based on evidence, even to drivers who, for example, have a low awareness of safe driving and have a lot of room for work improvement.

[0019] 2 is a block diagram showing an example of the configuration of a digital tachograph 10 according to an embodiment. The digital tachograph 10 includes a control unit 11, a time information acquisition unit 12, a position information acquisition unit 13, a speed information acquisition unit 14, an engine information acquisition unit 15, and a communication unit 16.

[0020] The control unit 11 is an arithmetic processing device (computer) that is responsible for the main control of the digital tachograph 10. The control unit 11 reads out a program for an in-vehicle device stored in a memory (not shown) and causes each part of the digital tachograph 10 to execute a predetermined process.

[0021] The time information acquisition unit 12 acquires current time information from a clock built into the digital tachograph 10 and / or from another server, a GPS satellite S, or the like via the network N. The position information acquisition unit 13 acquires position information (including latitude and longitude) of the vehicle 1 from the GPS satellite S. The speed information acquisition unit 14 acquires the traveling speed of the vehicle 1 from a speedometer or the like of the vehicle 1. The engine information acquisition unit 15 acquires engine information including engine on / off information corresponding to an ignition signal indicating whether the engine of the vehicle 1 is ignited or not. The ignition signal is a signal indicating whether the ignition of the vehicle 1 is on or off, and is, for example, a voltage signal of a detection circuit that detects the voltage of an ignition coil that ignites the engine. The time information acquisition unit 12, the position information acquisition unit 13, the speed information acquisition unit 14, and the engine information acquisition unit 15 acquire current time information, position information, speed information, and engine information (hereinafter also referred to as various data) at any time interval. The time interval for acquiring various data is preferably the lower limit of operation of the digital tachograph 10 to less than one minute while the engine of the vehicle 1 is running, and is arbitrary while the engine of the vehicle 1 is not running. A specific example of the time interval is, for example, 10 seconds.

[0022] The communication unit 16 functions as a transmitting unit that transmits operation information of the vehicle 1, including location information, traveling speed, engine information, etc. linked to time information, to the digital tachograph server 20 via the network N at any timing. The communication unit 16 also functions as a receiving unit that receives information from the digital tachograph server 20, the administrator PC 40, etc.

[0023] 3 is a block diagram showing an example of the configuration of a digital tachograph server 20 according to an embodiment. The digital tachograph server 20 includes a control unit 21, a communication unit 22, a time series data acquisition unit 23, an idling determination unit 24, an idling time calculation unit 25, and a presentation unit 26. The time series data acquisition unit 23 is an example of an acquisition unit, the idling determination unit 24 is an example of a determination unit, and the idling time calculation unit 25 is an example of a calculation unit.

[0024] The control unit 21 is an arithmetic processing device (computer) that is responsible for the main control of the digital tachograph server 20. The control unit 21 reads out a program for the digital tachograph server stored in a memory (not shown), and causes each unit of the digital tachograph server 20 to execute a predetermined process.

[0025] The communication unit 22 functions as a receiving unit that receives operation information of the vehicle 1 from the digital tachograph 10 via the network N. The communication unit 22 also functions as a transmitting unit that transmits information to the digital tachograph 10, the manager's PC 40, etc. The communication unit 22 receives operation information of the vehicle 1 transmitted from the digital tachograph 10 at any timing.

[0026] The time series data acquisition unit 23 acquires time series data in which the position information, speed information, and engine information included in the operation information of the vehicle 1, which are collected at predetermined time intervals by the communication unit 22, are linked to time information. However, the time series data may be generated by the digital tachograph 10. In this case, the time series data acquisition unit 23 acquires the time series data via the communication unit 22.

[0027] The idling determination unit 24 determines whether or not the vehicle is idling for each piece of time information, based on the speed information and the engine information. Note that the term "idling" in this disclosure means that the engine of the vehicle 1 is running, but the vehicle 1 is not running.

[0028] The idling time calculation unit 25 calculates the idling time at the point where idling occurred based on the position information and the judgment result of the idling judgment unit. The idling time is the time that the vehicle 1 continues to be in an idling state. If the engine information is off, or if the speed information is not zero even if the engine information is on, the idling time is zero.

[0029] The presentation unit 26 presents a map showing the point where idling occurred in a format according to the length of idling time. The presentation unit 26 is configured by a car navigation device, a display of another device, or the like.

[0030] 4 is a flowchart showing the processing steps of the information presentation method implemented by the digital tachograph server 20. The communication unit 22 receives operation information of the vehicle 1 via the network N (step S1). The time-series data acquisition unit 23 acquires time-series data in which the position information, speed information, and engine information included in the operation information of the vehicle 1, which are collected at predetermined time intervals by the digital tachograph 10, are linked to time information (step S2).

[0031] Next, the idling determination unit 24 determines whether or not the vehicle is idling for each time based on the speed information and engine information (step S3). When the speed information indicates zero speed and the engine information indicates on, the idling determination unit 24 determines that the vehicle is idling, i.e., that idling is occurring. When the vehicle is not idling, i.e., that idling is not occurring (No in step S3), the digital tachograph server 20 ends the process.

[0032] If idling is occurring (Yes in step S3), the digital tachograph server 20 proceeds to the process of step S4. In step S4, the idling time calculation unit 25 calculates the idling time, which is the time that the vehicle 1 continued to be in an idling state at the point where idling occurred, based on the position information and the judgment result of the idling judgment unit. The point where idling occurred is the position indicated by the vehicle's position information linked to the time information of the time when it was judged to be in an idling state.

[0033] 5 is a diagram showing an example of time series data. The time series data includes at least position information, speed information, and engine information linked to the acquisition time, which is time information. At the acquisition times 12:00:00 and 12:00:10, the speed is not zero and the engine information is on, so the vehicle 1 is running and idling is not occurring. At the acquisition times 12:30:00 and 12:30:10, the speed is zero and the engine information is off, so the vehicle 1 and its engine are stopped and idling is not occurring.

[0034] On the other hand, at the acquisition times 12:45:00, 12:45:10, and 12:45:20, the speed is zero and the engine information is on, so the vehicle 1 is stopped but the engine is running. Therefore, at the acquisition times 12:45:00, 12:45:10, and 12:45:20, the idling determination unit 24 determines that idling has occurred. The idling time calculation unit 25 calculates the idling time. The idling time calculation unit 25 calculates the accumulated idling time from the difference between the acquisition times as the idling time. Assuming that idling has occurred at the acquisition time 12:45:00, the idling time at the acquisition time 12:45:10 is 10 seconds, and the idling time at the acquisition time 12:45:20 is 20 seconds.

[0035] Finally, the presentation unit 26 presents a map showing the point where idling occurred in a form according to the length of the idling time, based on the position information and the calculated idling time (step S5).

[0036] In the digital tachograph server 20 according to the embodiment, the display unit 26 displays an image in which the points where idling occurred are superimposed on a map in a manner according to the length of the idling time, so that the user can grasp the length of the idling time at each point on the map. Therefore, the idling time can be easily grasped for each place where the vehicle 1 is stopped, so that the occurrence of idling can be grasped in detail. Therefore, it becomes possible to provide appropriate guidance for improving the driver's work, and to reduce the wasteful idling time of the vehicle 1.

[0037] The state of the point where idling occurred that the presentation unit 26 superimposes on the map is a state according to the length of the idling time. This state is not particularly limited, but the presentation unit 26 presents, for example, an image in which the point is superimposed in a state in which at least one of the size, color, and shape is changed according to the length of the idling time. This allows the user to easily visually grasp the length of the idling time for each point. For example, when multiple points with similar idling times are close to each other, these multiple points can be surrounded by curved lines, and the inside can be colored according to the length of the idling time, and superimposed on the map.

[0038] In addition, the location can be displayed by at least one of the size, color, and shape of the mark according to the length of the idling time. The mark may be, for example, a circle, and the longer the idling time, the larger the size (diameter, area) of the circle displayed. This allows the user to easily visually grasp the length of the idling time at each location.

[0039] Furthermore, the presentation unit 26 may display the idling time at each point, including whether or not the vehicle is idling, in a mesh format. The mesh format is a format in which the map is divided into fine meshes, and each mesh is displayed with a shade of color according to the length of the idling time. This type of format also allows the user to easily visually grasp the length of the idling time at each point.

[0040] The map may be, for example, a satellite photo acquired by a GPS satellite S. This makes it possible to easily acquire an accurate map.

[0041] Furthermore, the display unit 26 may display the location of loading and unloading of luggage on the map in addition to the location where idling occurred. This makes it possible to display useful information such as the location of loading and unloading of luggage in addition to the length of idling time.

[0042] FIG. 6 is a diagram showing an example of an image presented by the presentation unit 26. FIG. 6 is an example of an image in which an idling occurrence point is superimposed on a map. The map shown in FIG. 6 is a schematic representation of a satellite photograph, and by using a satellite photograph as a map, it becomes easier to grasp the detailed situation of the idling occurrence point. In FIG. 6, the idling occurrence point is represented by a circular mark, and the point with a longer idling time is represented by a larger circle. The image at the top of FIG. 6 shows that point X in particular is displayed as a large circle on the map displayed by the presentation unit 26 in the default state, and the idling time is long. In FIG. 6, circles showing multiple points close to each other are displayed as connected shapes.

[0043] By performing a specified operation on the image shown at the top of Figure 6, the user can enlarge the area at point X. The enlarged image is shown at the bottom of Figure 6. In the image at the bottom of Figure 6, point Y on the road near the center is displayed as a large circle, indicating that idling time is long. This allows operators to analyze the causes of long idling time at point X, and especially point Y, and develop measures to reduce unnecessary idling time of vehicles.

[0044] The administrator PC 40 may receive the calculation results by the idling time calculation unit 25 from the digital tachograph server 20 via the network N and function as an information presentation device. That is, the administrator PC 40 may present an image on a map in which the point where idling occurred is superimposed in a manner according to the length of the idling time, similar to the presentation unit 26. Also, a server other than the digital tachograph server 20 may receive the calculation results by the idling time calculation unit 25 from the digital tachograph server 20, function as the presentation unit 26 to create a map, and send it to the administrator PC 40.

[0045] The information presentation system 100 includes a digital tachograph server 20 and a digital tachograph 10 that is mounted on a vehicle 1 and transmits driving information. This allows the digital tachograph server 20 to obtain the necessary time series data from the digital tachograph 10, and makes it possible to grasp the length of idling time based on the information of the vehicle 1 being used.
