It is sufficient that vehicles having the same are classified into the same classification.

Based on the comparison result by the comparison unit 53, the extraction unit 54 extracts a vehicle having relatively large power consumption (for example, total power consumption by the operating electric load 23).
For example, the extraction unit 54 uses a predetermined determination threshold for power consumption set according to a predetermined area and each vehicle type, and extracts a vehicle having a power consumption larger than the determination threshold.
For example, as shown in FIG. 2, for a cloudy area A after raining, a vehicle ak having a power consumption larger than the determination threshold value α among a plurality of vehicles (a1,..., Ak,...). Extracted.
Further, for a clear sky area B, a vehicle bk having a power consumption larger than the determination threshold β is extracted from a plurality of vehicles (b1,..., Bk,...).
Note that the predetermined determination threshold for power consumption may be a fixed value set in advance for each predetermined area and each vehicle type, for example, the power consumption of a plurality of vehicles for each same vehicle type in the predetermined area. It may be a value that changes according to the fluctuation of the input value when calculated by a predetermined calculation method, such as an average value.

The notification control unit 55 transmits, by the communication device 51, a notification instruction signal that instructs the vehicle extracted by the extraction unit 54 to perform predetermined notification.
The predetermined notification is, for example, output of a message notifying that the total power consumption of various electric loads 23 is larger than that of the surrounding vehicles, for example, the electric load 23 having a low operation rate in the surrounding vehicles is operating. Such as outputting a message to notify the user.

  The vehicle electrical load monitoring system 10 according to the present embodiment has the above-described configuration. Next, the operation of the vehicle electrical load monitoring system 10 will be described with reference to the accompanying drawings.

First, for example, in the operation of the in-vehicle terminal device 11 illustrated in FIG. 3, terminal-side information including information related to various states of the electric load 23 is transmitted to the outside by the communication device 31 of the navigation system 24 in step S01.
In step S02, it is determined whether a notification instruction signal transmitted from the vehicle electrical load monitoring server 12 has been received.
If this determination is “NO”, the flow proceeds to the end.
On the other hand, if the determination is “YES”, the flow proceeds to step S03.

In step S03, the function ranks of the various electric loads 23 in operation are acquired.
For example, as shown in FIG. 4, this function rank indicates a classification set in advance for various electric loads 23, and the electric load 23 is, for example, various devices related to traveling of a vehicle (for example, electronic Throttle devices, brake devices, steering devices, etc.), various devices related to vehicle safety (eg, lighting devices, seat belt devices, etc.), and various devices related to passenger comfort (eg, dew condensation removing devices, defrosting devices) And freeze-free devices, air conditioners, various heaters, etc.) and various devices related to convenience (for example, cigarette lighters, rear seat monitors, sound devices, etc.).

In step S04, for example, by determining whether or not the operating electrical load 23 is other than various devices related to traveling of the vehicle or other devices related to safety, the operating electrical load is controlled. It is determined whether or not.
If this determination is “NO”, the flow proceeds to step S 05, and in this step S 05, failure diagnosis processing for diagnosing whether or not an abnormality has occurred in the operating electric load 23 is executed. Proceed to
On the other hand, if this determination is “YES”, the flow proceeds to step S 06.

In step S06, notification according to the notification instruction signal is executed.
In step S07, the occupant's intention for whether or not to execute the predetermined control operation is confirmed based on a signal output from the input device 34 by the occupant's input operation according to the notification.
In step S08, it is determined whether or not the execution of the predetermined control operation is permitted by the occupant.
If this determination is “NO”, the flow proceeds to step S 09, and in this step S 09, execution of the predetermined control operation is prohibited and the flow proceeds to the end.
On the other hand, if this determination is “YES”, the flow proceeds to step S 10, in which the predetermined control operation is executed and the flow proceeds to the end.

Further, for example, in the operation of the vehicle electrical load monitoring server 12 shown in FIG. 5, in step S21, the terminal-side information transmitted for each vehicle is received, and the state of the electrical load 23 of each vehicle is acquired.
In step S22, weather information (for example, temperature, precipitation, weather, etc.) is acquired.
In step S23, an area having the same weather information within a predetermined distance range from the position of each vehicle is set as the predetermined area.

  In step S24, a predetermined map is searched based on information on the state of various electric loads 23 included in the terminal-side information of each vehicle and vehicle type information, and the vehicle is consumed by the electric load 23 for each vehicle. Power consumption (for example, total power consumption by the operating electrical load 23 and individual power consumption for each operating electrical load 23) is acquired. And a some vehicle is classified for every same vehicle type in a predetermined area, and power consumption is compared between several vehicles for every classification.

In step S25, a vehicle with relatively large power consumption (for example, total power consumed by the operating electric load 23) is extracted as a notification target for each classification.

As described above, according to the fuel consumption reduction support system 10 and the vehicle electrical load monitoring server 12 according to the embodiment of the present invention, by notifying a vehicle in which the power consumption of the various electrical loads 23 is relatively large, Regardless of the amount of stored energy that can be consumed by the vehicle, it is possible to suppress excessive operation of the electrical load 23 and improve fuel efficiency. Furthermore, the state of a power storage device such as a battery mounted on the vehicle can be maintained.
In addition, for example, when the driver of the vehicle forgets to stop the operation of the predetermined electric load 23, the driver's attention can be alerted, and the fuel efficiency can be improved.

In addition, since the comparison of power consumption among a plurality of vehicles is performed for each vehicle type, appropriate relative comparison and notification can be performed even when the power source capacity and the electrical load 23 differ depending on the vehicle type.
In addition, since the power consumption is compared between a plurality of vehicles in which the weather information within a predetermined distance range from the vehicle location is within the same area, the state of the electrical load 23 changes according to the weather information. Even so, appropriate relative comparison and notification can be performed.

  Furthermore, according to the fuel consumption reduction support system 10 and the vehicle-mounted terminal device 11 according to the embodiment of the present invention, when a predetermined control operation is permitted to be executed by a passenger in a vehicle in which the power consumption of the electric load 23 is relatively large. Since the power consumption is reduced or the power supply is cut off automatically for the predetermined electrical load 23, the convenience can be improved. In addition, it is possible to prevent the predetermined control operation from being executed in a state that is not predicted by the occupant, and to prevent the occupant from feeling uncomfortable with the change in the state of the electric load 23.

In the above-described embodiment, the information related to the state of the various electric loads 23 included in the terminal-side information includes the state of the switch indicating on / off of the operation and the state of the operation dial indicating the degree of the operation state. Although it is information, it is not limited to this, for example, consumption of each electric load 23 in operation based on detection signals output from various current sensors mounted on the vehicle and detection signals output from the battery sensor 22a Information on power and current consumption may be used.
Furthermore, in the above-described embodiment, the comparison unit 53 of the vehicle electrical load monitoring server 12 compares power consumption among a plurality of vehicles for each identical vehicle type in a predetermined area. Regardless of the classification for each vehicle type, the power consumption may be simply compared among a plurality of vehicles in a predetermined area. In this case, for example, the comparison unit 53 stores in advance a predetermined conversion map for converting the power consumption for each vehicle type so that the comparison of the power consumption between different vehicle types is appropriate, and is obtained based on the terminal-side information. A value obtained by converting the consumed power using a predetermined conversion map is compared among a plurality of vehicles.
Thereby, the comparison of the power consumption between different vehicle types can be performed appropriately, the number of vehicles to be compared can be increased, and the reliability of the comparison result can be improved.

  In the embodiment described above, the comparison unit 53 may compare the individual power consumption for each electric load 23 when comparing the power consumption among a plurality of vehicles. In this case, the predetermined notification instructed by the notification instruction signal of the notification control unit 55 is, for example, output of a message notifying that the power consumption is larger than that of the surrounding vehicle for each electric load 23.
