<First Embodiment>
1. Configuration of Information Processing System 1 The configuration of the information processing system 1 will be described with reference to FIG. The information processing system 1 includes an information processing device 3 and an information center 5. The information processing device 3 is an in-vehicle device mounted on a vehicle (an example of a moving body) 7. The information processing apparatus 3 is a computer that includes a CPU, a RAM, a ROM, and the like. The information processing device 3 executes processing to be described later with a program stored in the ROM.

  Functionally, the information processing apparatus 3 includes a measurement value acquisition unit 9, a storage unit 11, a measurement environment determination unit 13, a measurement value transmission unit 15, a position information acquisition unit 17, a measurement environment acquisition unit 18, and a measurement environment storage unit 19. Is provided. The function of each unit will be described later.

  The vehicle 7 includes a measurement sensor 21, a GPS 23, and a communication device 25 in addition to the information processing device 3. The measurement sensor 21 measures the intake pressure of the engine provided in the vehicle 7. The engine intake pressure is an example of the state of the vehicle. The GPS 23 specifies the position of the vehicle 7. The communication device 25 communicates with the information center 5.

  The information center 5 is outside the vehicle 7. The information center 5 includes a control unit 27 and a communication device 29. The control unit 27 is a computer including a CPU, RAM, ROM, and the like. The control unit 27 executes processing to be described later using a program stored in the ROM. The control unit 27 functionally includes a reception unit 31 and a moving body state determination unit 33. The function of each unit will be described later. The communication device 29 communicates with the information processing device 3.

2. Measurement Value Transmission Process Performed by Information Processing Device 3 A measurement value transmission process repeatedly executed by the information processing device 3 every predetermined time will be described with reference to FIG. In step 1 of FIG. 2, the position information acquisition unit 17 acquires the position information of the vehicle 7 using the GPS 23. This position information is hereinafter referred to as first position information.

In step 2, the measurement value acquisition unit 9 acquires a measurement value from the measurement sensor 21 and stores it in the storage unit 11.
In step 3, the position information acquisition unit 17 acquires the position information of the vehicle 7 using the GPS 23. This position information is hereinafter referred to as second position information.

  In step 4, the measurement environment acquisition unit 18 acquires a road condition in a section (hereinafter referred to as a measurement section) from the position specified by the first position information to the position specified by the second position information. . Specifically, this is performed as follows. The measurement environment storage unit 19 stores map information in advance. This map information stores road conditions at each position for each position. The road situation includes road elevation, road shape (straight or curved), road inclination, road irregularities, and the like. The measurement environment acquisition unit 18 acquires the road situation in the measurement section from the map information.

  In step 5, the measurement environment determination unit 13 determines whether or not the road condition acquired in step 4 is within a preset reference range. Here, the reference range is a range in which the influence of the road condition on the measurement value of the measurement sensor 21 is relatively small and the measurement value can be trusted. For example, when the road condition is the altitude of the road, a range in which the altitude is equal to or lower than a predetermined threshold is the reference range. In addition, when the road condition is a road shape, a range in which the road curvature is equal to or less than a predetermined threshold is a reference range. When the road condition is a road slope, a range in which the magnitude of the slope is equal to or less than a predetermined threshold is a reference range. Further, when the road condition is road unevenness, a range in which the size of the unevenness is a predetermined threshold value or less is a reference range.

If the road condition is within the reference range, the process proceeds to step 6. If the road condition is outside the reference range, the present process is terminated.
In step 6, the measurement value transmission unit 15 transmits the measurement value acquired in step 2 and stored in the storage unit 11 to the information center 5 using the communication device 25.

3. Mobile body state determination process executed by the information center 5 The mobile body state determination process executed by the information center 5 will be described. The receiving unit 31 of the information center 5 receives the measurement value transmitted by the information processing device 3 using the communication device 29. Next, the moving body state determination unit 33 determines whether or not the received measurement value is within a preset normal range. The normal range may be a fixed range or may be a statistically set range based on measurement values transmitted from the plurality of vehicles 7.

4). Effects produced by the information processing system 1 and the information processing device 3 (1A) The information processing device 3 transmits a measurement value on condition that the measurement environment (road condition) is within the reference range. Therefore, the measurement value when the measurement environment is out of the reference range does not have to be transmitted, so that the time for using the communication device 25 for transmitting the measurement value can be suppressed.

  In addition, there is a high possibility that the measurement value when the measurement environment is outside the reference range does not accurately reflect the state of the moving body (vehicle 7) due to the influence of the measurement environment. Since the information processing apparatus 3 does not transmit the measurement value when the measurement environment is outside the reference range, it can suppress the transmission of the measurement value that does not accurately reflect the state of the moving body.

  (1B) The information processing apparatus 3 acquires the measurement environment corresponding to the position information acquired by the position information acquisition unit 17 from the measurement environment storage unit 19. As a result, the measurement environment can be easily acquired.

  (1C) The information processing device 3 acquires the measurement environment in the measurement section (the section including the position where the measurement value is acquired). As a result, it is possible to more accurately determine whether or not the measurement environment when the measurement value is acquired is within the reference range.

<Second Embodiment>
Since the basic configuration of the second embodiment is the same as that of the first embodiment, the description of the common configuration will be omitted, and differences will be mainly described.

The planned position is a position in front of the traveling direction of the vehicle 7 and a measurement value is scheduled to be acquired in step 14 described later. The planned position can be, for example, a position Xm ahead of the vehicle 7. Further, the planned position can be a position where the vehicle 7 reaches Y seconds after that point. In this case, the planned position can be specified from the speed of the vehicle 7 and Y seconds.

  For example, as shown in FIG. 4A, when the vehicle 7 is traveling on a road 36 without a branch, the planned position 35 can be one place in front of the vehicle 7. Further, as shown in FIG. 4B, when the vehicle is traveling on a road 36 that branches forward (for example, there is an intersection), a planned position 35 can be set at each branch destination.

  The measurement environment acquisition unit 18 uses the map information stored in the measurement environment storage unit 19 to acquire the road situation at the planned position. The configuration of the measurement environment storage unit 19 is the same as that of the first embodiment.

  In step 13, the measurement environment determination unit 13 determines whether or not the road condition acquired in step 12 is within a preset reference range. As in the example illustrated in FIG. 4B, when there are a plurality of planned positions 35, it is determined that any one of them is out of the reference range if the road condition is out of the reference range. When the road condition is within the reference range, the process proceeds to step 14, and when it is out of the reference range, the present process is terminated.

In step 14, the measurement value acquisition unit 9 acquires a measurement value from the measurement sensor 21.

For this reason, it is possible to determine whether or not the measurement environment is within the reference range before acquiring the measurement value. If the measurement environment is outside the reference range, the measurement value can be prevented from being acquired. As a result, the processing burden on the information processing apparatus 3 can be reduced.

  In step 23, the measurement environment determination unit 13 determines whether or not the road condition acquired in step 22 is within a preset reference range. If the road condition is within the reference range, the process proceeds to step 24. If the road condition is outside the reference range, the process ends.

In step 24, the measurement value acquisition unit 9 acquires a measurement value from the measurement sensor 21.
