Summary of the Invention

Problems to be Solved by the Invention

Embodiments for Carrying Out the Invention

[0009] Preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0010] With reference to FIG. 1, the configuration of an information processing system 100 including an information processing apparatus 1 according to the embodiment will be described. The information processing system 100 includes, for example, an information processing apparatus 1 that can be mounted on a vehicle and an information processing server 2. The information processing apparatus 1 and the information processing server 2 are connected via a network N.

[0011] In addition to the information processing apparatus 1, various sensors such as an accelerator sensor, a brake sensor, a gyro sensor, and an acceleration sensor, and a GPS (Global Positioning System) receiver can be appropriately mounted on the vehicle.

[0012] As a functional configuration, the information processing server 2 includes, for example, a control unit 21 and a storage unit 22. Note that the components of the information processing server 2 are not limited to this, and any components can be appropriately added as needed.

[0013] The control unit 21 has a function of executing various processes in the information processing server 2. For example, the control unit 21 executes a process of receiving data related to the driving status transmitted from each vehicle and storing it in the storage unit 22. The data related to the driving status can include, for example, the measurement time and the position information of the vehicle at that measurement time.

[0014] In addition to the data related to the driving status, the storage unit 22 stores various data.

[0015] As a functional configuration, the information processing device 1 includes, for example, a control unit 11 and a storage unit 12. Note that the components of the information processing device 1 are not limited to this, and any components can be appropriately added as needed.

[0016] The information processing device 1 includes, for example, a function as a car navigation device. The control unit 11 has a function of executing various processes in the information processing device 1 in addition to navigation processing. Some of the processes executed by the control unit 11 are exemplified below.

[0017] The control unit 11 receives an input of a search instruction instructing to search for a moving route along which the vehicle moves from the user. In this case, the control unit 11 functions as a reception unit. The input operation of the search instruction can adopt, for example, the same operation as the operation when inputting a search instruction to a car navigation device.

[0018] Based on the search instruction, the control unit 11 searches for the travel route of the vehicle. In this case, the control unit 11 will function as a search unit. The search for the travel route can be realized by a process similar to the travel route search process executed by, for example, a car navigation device. For example, when receiving a search instruction specifying the departure location, departure date and time, and destination, one or more travel routes between the departure location and the destination are searched.

[0019] The control unit 11 calculates the estimated arrival time when traveling on the searched travel route. In this case, the control unit 11 will function as a calculation unit. The estimated arrival time is calculated, for example, as follows.

[0020] Based on the data on the driving status of a plurality of vehicles stored in the storage unit 22 of the information processing server 2, the control unit 11 calculates statistical data on the travel time (travel time) of the vehicle, and based on the statistical data, calculates the time required for the vehicle to travel the travel route as the statistical travel time.

[0021] The statistical data and the statistical travel time can be calculated, for example, for each predetermined road link. A road link is a road section specified by connecting road nodes representing characteristic points of the road (for example, intersections, corners, dead ends, etc.).

[0022] Based on the statistical travel time on the travel route and the departure date and time, the control unit 11 calculates the estimated arrival time when the vehicle arrives at the destination. The calculated estimated arrival time is guided to the user by character display or voice output when guiding the travel route.

[0023] The control unit 11 acquires the statistical travel time (hereinafter also referred to as "statistical travel time") calculated based on the statistical data corresponding to the travel route and the travel time of the vehicle traveling on the travel route (hereinafter also referred to as "travel time of the vehicle"). In this case, the control unit 11 will function as an acquisition unit. The statistical travel time and the travel time of the vehicle may be acquired, for example, in units of road links.

[0024] The control unit 11 compares the acquired travel time of the vehicle with the acquired statistical travel time, and determines the deviation between the travel time of the vehicle and the statistical travel time. In this case, the control unit 11 functions as a determination unit.

[0025] When the control unit 11 determines that the travel time of the vehicle is longer than the statistical travel time, the estimated arrival time at the destination is corrected to be longer (take more time) than the time calculated based on the statistical travel time, and the corrected estimated arrival time is guided to the user by character display or voice output. In this case, the control unit 11 functions as an arrival time correction unit.

[0026] Here, when the control unit 11 determines the deviation between the travel time of the vehicle and the statistical travel time, the travel times corresponding to one or more identical road links may be compared with each other.

[0027] Also, when the control unit 11 determines that the travel time of the vehicle is not longer than the statistical travel time, the estimated arrival time does not need to be corrected.

[0028] Furthermore, the control unit 11 may machine-learn the comparison result between the travel time of the vehicle and the statistical travel time, and be able to determine whether the user driving the vehicle is a user who drives slower than the statistical data based on the learned learning model. In this case, the control unit 11 functions as a learning unit. The learning model can be stored in the storage unit 12, for example.

[0029] When the control unit 11 determines, using the learning model, that the user driving the vehicle is a user who drives slower than the statistical data, the estimated arrival time is corrected so that the estimated arrival time is longer than the time calculated based on the statistical travel time. In this case, it may be corrected to the estimated arrival time when traveling on the travel route at the speed limit, or corrected so that the estimated arrival time is the time extended by a predetermined ratio with respect to the statistical travel time.

[0030] By correcting the scheduled arrival time as described above, it becomes possible to guide the user with a scheduled arrival time that matches the user's perception for a user who travels later than the statistical data.

[0031] Next, referring to FIG. 2, an example of the operation of the information processing apparatus 1 according to the embodiment will be described.

[0032] First, the control unit 11 of the information processing apparatus 1 searches for the moving route of the vehicle based on the search instruction received from the user (step S101).

[0033] Subsequently, the control unit 11 of the information processing apparatus 1 calculates the scheduled arrival time when traveling on the searched moving route (step S102).

[0034] Subsequently, the control unit 11 of the information processing apparatus 1 acquires the moving time of the vehicle and the statistical moving time, and determines whether the moving time of the vehicle is longer than the statistical moving time (step S103). If this determination is NO (step S103; NO), the control unit 11 transfers the process to step S105 described later.

[0035] In step S103 above, when it is determined that the moving time of the vehicle is longer than the statistical moving time (step S103; YES), the control unit 11 of the information processing apparatus 1 corrects the scheduled arrival time at the destination so as to be longer than the time calculated based on the statistical moving time (step S104).

[0036] Subsequently, the control unit 11 of the information processing apparatus 1 causes the scheduled arrival time corrected in step S104 to be displayed on, for example, the display of the information processing apparatus 1 (step S105). Then, the control unit 11 transfers the process to step S103 described above.

[0037] As described above, according to the information processing apparatus 1 in the embodiment, the statistical travel time calculated based on the statistical data corresponding to the travel route of the vehicle and the travel time of the vehicle traveling on the travel route are acquired. When the travel time of the vehicle traveling on the travel route is longer than the statistical travel time corresponding to the section traveled by the vehicle, the scheduled arrival time at the destination can be corrected so that it takes more time than the time calculated based on the statistical travel time.

[0038] Thereby, it becomes possible to guide the scheduled arrival time according to the user to the user who travels later than the statistical data.

[0039] Note that the present invention is not limited to the above-described embodiment, and can be implemented in various other forms without departing from the gist of the present invention. Therefore, the above embodiment is merely an example in every respect and is not to be construed in a limiting sense.

[0040] In the above-described embodiment, when the control unit 11 of the information processing apparatus 1 determines that the travel time of the vehicle is longer than the statistical travel time, the scheduled arrival time is corrected. However, the condition for correcting the scheduled arrival time is not limited to this. For example, when it is determined that the travel time of the vehicle is longer than the statistical travel time by a predetermined time or more, the scheduled arrival time may be corrected.

[0041] Further, in the above-described embodiment, a part of the elements that function by the control unit 11 of the information processing apparatus 1 may be caused to function by the control unit 21 of the information processing server 2.
