(First embodiment)
FIG. 1 is a diagram illustrating a use environment of the information processing apparatus 100 according to the first embodiment. The information processing apparatus 100 is mounted on the vehicle 10. The information processing apparatus 100 wirelessly transmits driving information of a vehicle 10 on which the information processing apparatus 100 is mounted (hereinafter referred to as the host vehicle 10a) to the outside. In addition, the information processing apparatus 100 receives driving information of another vehicle 10 (hereinafter referred to as another vehicle 10b) transmitted by the other information processing apparatus 100 wirelessly, and the vehicle 10 on which the information processing apparatus 100 is mounted. It is displayed with the driving information.

  That is, the information processing apparatus 100 according to the present embodiment displays the driving information of the host vehicle 10 a together with the driving information of the other vehicle 10 b that is traveling before and after the vehicle 10. That is, the driver of the own vehicle 10a can compare his / her driving information with driving information of the driver of the other vehicle 10b under the same conditions as the driver. Accordingly, the driver can easily be aware of eco-driving.

  Here, the driving information includes, for example, fuel consumption. Further, the driving information includes at least one of a ratio of the time when the acceleration is equal to or higher than the entire driving time, a rate of change of acceleration during acceleration, and a ratio of idling time to the total driving time.

  The information processing apparatus 100 receives the driving information of the other vehicle 10b that faces in the same direction as the host vehicle 10a. In addition to this driving information, the other vehicle 10b that heads in the opposite direction to the host vehicle 10a. The driving information may also be received.

  FIG. 2 is a block diagram illustrating a functional configuration of the information processing apparatus 100. The information processing apparatus 100 includes a transmission unit 120, a reception unit 130, and a display unit 140. The transmission unit 120 wirelessly transmits driving information of the host vehicle 10a to the outside. In addition, the transmission part 120 acquires driving information from the other apparatus mounted in the own vehicle 10a.

  The receiving unit 130 wirelessly receives driving information of the other vehicle 10b from the information processing apparatus 100 mounted on the other vehicle 10b. The display unit 140 displays the driving information of the other vehicle 10b received by the receiving unit 130 and the driving information of the host vehicle 10a so as to correspond to each other.

  Note that each component of the information processing apparatus 100 illustrated in FIG. 2 is not a hardware unit configuration but a functional unit block. Each component of the information processing apparatus 100 is centered on an arbitrary computer CPU, memory, a program that realizes the components shown in the figure loaded in the memory, a storage unit such as a hard disk for storing the program, and a network connection interface. It is realized by any combination of hardware and software. There are various modifications of the implementation method and apparatus.

  FIG. 3 shows an example of data displayed by the display unit 140 of the information processing apparatus 100. In the example shown in the figure, the display unit 140 displays the driving information of the host vehicle 10a and the driving information of the other vehicle 10b in correspondence with each item of the driving information. For this reason, the driver of the vehicle 10 can compare his / her driving information with driving information of other drivers who are in the same conditions as the driver.

  In FIG. 3, “the ratio of the time during which the acceleration was equal to or greater than the entire driving time” is displayed as “driving with less acceleration / deceleration”, and “the rate of change in acceleration during acceleration” is “ “Soft Accelerator” is displayed, and “Ratio of idling time to total operating time” is displayed as “Operation with little idling”.

In FIG. 3, the driving information includes an item “early accelerator off”. “Early accelerator off” means L / L ₀ × 100 (%), where L _{0 is} the distance that can be traveled only by inertial energy after the accelerator is off, and L is the distance that is decelerated in actual driving. Defined.

Here, the evaluation unit 150 calculates L ₀ as follows. First, the kinetic energy consumption until the stop after the accelerator is turned off is determined by the following equation (1). Formula (1) is defined by energy consumption due to air resistance, energy consumption due to rolling resistance, and energy consumption due to gradient resistance. In equation (1), the left side represents the kinetic energy of the vehicle 10 when the accelerator is off, the first term on the right side represents energy consumption due to air resistance, the second term represents energy consumption due to rolling resistance, and the third term represents energy consumption due to gradient resistance. ing.

When this is organized for L _0, and becomes the following equation (2).

By using this formula, the evaluation unit 150 can calculate the _{L 0.}

  As described above, according to the present embodiment, the driver of the vehicle 10 can compare his / her driving information with driving information of other drivers who are in the same conditions as the driver. Accordingly, the driver can easily be aware of eco-driving.

  In the present embodiment, the driving information includes at least one of the ratio of the time when the acceleration is equal to or higher than the total driving time, the rate of change of acceleration during acceleration, and the ratio of the idling time to the total driving time. Contains. These pieces of information are unlikely to depend on the vehicle type, unlike fuel consumption. Therefore, it can be directly compared with the driver of the surrounding car whether or not the driver is performing the eco-driving. In this case, the driver is more conscious of eco-driving. In addition, since there is no need to install a center server, the initial construction cost and operation cost can be reduced.

(Second Embodiment)
FIG. 4 is a block diagram illustrating a functional configuration of the information processing apparatus 100 according to the second embodiment. The information processing apparatus 100 has the same configuration as the information processing apparatus 100 according to the first embodiment except that the evaluation unit 150 is provided.

  The evaluation unit 150 performs a process of converting each item of the driving information into an index value. The transmission unit 120 transmits an index value as driving information of the host vehicle 10a. The receiving unit 130 transmits the converted index value as the driving information of the other vehicle 10b. The display unit 140 displays the index value as the driving information of the host vehicle 10a and the driving information of the other vehicle 10b.

  First, the evaluation unit 150 calculates the ratio of the constant speed traveling time to the entire driving time as an index value of “the ratio of the time when the acceleration is equal to or greater than a certain amount with respect to the entire driving time”. For example, the evaluation unit 150 performs the following processing.

  First, the evaluation unit 150 acquires speed data for every predetermined time (for example, every second) for a predetermined time (for example, for 10 seconds). Then, the evaluation unit 150 calculates an average speed within this time (for example, 10 seconds). Next, the evaluation unit 150 calculates a difference between the minimum speed and the average speed and a difference between the maximum speed and the average speed within the time (for example, 10 seconds). When these two differences are within a predetermined reference value, it is determined that the time (for example, 10 seconds) is constant speed traveling.

In addition, when the rate of change of acceleration during acceleration is large, the fuel efficiency generally deteriorates. Therefore, the evaluation unit 150 calculates an index value of “the rate of change in acceleration during acceleration” as follows.
As shown in FIG. 5, the evaluation unit 150 holds in advance data indicating an ideal value of the relationship between time and speed after starting acceleration. Then, a difference (that is, area B) between the moving distance within the evaluation time when ideal acceleration is performed (that is, area A in FIG. 5) and the moving distance during the actual evaluation time is calculated. Next, the evaluation unit 150 calculates the ratio of the area B to the area A as an index value of “the rate of change in acceleration during acceleration”.

  In this way, even when the average acceleration is the same, for example, when acceleration is performed as shown in FIGS. 6B and 6C, compared to when acceleration is performed as shown in FIG. 6A. Therefore, the index value of “the rate of change in acceleration during acceleration” is low.

  In addition, the evaluation unit 150 calculates an index value of “ratio of idling time to total driving time” as follows.

  First, the evaluation unit 150 holds in advance a speed threshold value (for example, 1 km / hour) for determining idling. And the time which was below a threshold value among the total driving time is calculated, and the ratio of the calculated time with respect to the total driving time is calculated as an index value.

  And the evaluation part 150 arranges these each index value in several steps, and calculates an evaluation value by evaluating by AE, for example.

  The evaluation unit 150 also calculates the average value and standard deviation of the index values of the respective evaluation items using the past index values, and further calculates the deviation value of the latest index value, and the display unit 140 displays It is good also as an evaluation value to do.

  Further, the evaluation unit 150 calculates the average value and standard deviation of the index values of the respective evaluation items using the index value of the other vehicle 10b, and then calculates the deviation value of the index value of the own vehicle 10a. The evaluation value displayed by 140 can also be used.

  FIG. 7 shows an example of data displayed by the display unit 140 of the information processing apparatus 100. In the example shown in this figure, the display unit 140 displays the evaluation value calculated by the evaluation unit 150 for each item in addition to the display shown in FIG.

  Also according to this embodiment, the same effect as that of the first embodiment can be obtained.

(Third embodiment)
FIG. 8 is a block diagram illustrating a functional configuration of the information processing apparatus 100 according to the third embodiment. The information processing apparatus 100 has the same configuration as that of the information processing apparatus 100 described in the second embodiment except that the information processing apparatus 100 includes the storage unit 110.

  FIG. 9 is a diagram illustrating the data stored in the storage unit 110 in a table format. The storage unit 110 stores driving information of the plurality of other vehicles 10b received by the receiving unit 130. In the example shown in the figure, the storage unit 110 stores driving information of the other vehicle 10b in association with the time when the driving information is received.

  FIG. 10 shows an example of display performed by the display unit 140. In the example shown in the figure, the display unit 140 displays a plurality of driving information stored in the storage unit 110 together with driving information of the host vehicle 10a. More specifically, the display unit 140 ranks the plurality of driving information stored in the storage unit 110 and the driving information of the host vehicle 10a in addition to the example shown in FIG. (Rank) and the best score of driving information are also displayed for each item. The display unit 140 performs this ranking by comparing the numerical values indicated by the driving information.

  According to the present embodiment, the storage unit 110 stores driving information of a plurality of other vehicles 10b. The display unit 140 performs display using information stored in the storage unit 110. For this reason, since the driver of the own vehicle 10a can compare the driving information of the own vehicle 10a with the driving information of many vehicles 10, it becomes easier to be aware of whether or not he / she is performing an eco-driving.

  The display unit 140 may display only the driving information received before a predetermined time (for example, 10 minutes before) from the current time among the driving information stored in the storage unit 110. Thereby, according to this embodiment, the driving information regarding the other vehicle 10b which has the driving environment similar to the driving environment of the own vehicle 10a can be selected with high precision.

  As mentioned above, although embodiment of this invention was described with reference to drawings, these are the illustrations of this invention, Various structures other than the above are also employable.
