Hereinafter, the present invention will be clarified by describing embodiments of the present invention in detail with reference to the drawings.
(Outline of configuration of fuel efficiency information provision system)
FIG. 1 is a functional block diagram showing a fuel efficiency information providing system as one embodiment of the present invention.
This fuel consumption information providing system 100 includes a reference travel time information holding unit 110, a reference fuel consumption information / best fuel consumption information holding unit 120, a travel time information acquisition unit 130, a fuel consumption information acquisition unit 140, and a fuel consumption information provision unit 150. It is connected to the controller 160. Further, the driving mode identification unit 170, the travel time reduction / delay information generation unit 180, and the fuel consumption fluctuation information generation unit 190 are connected to the system controller 160, respectively.

In this embodiment, the driving mode identifying unit 170 includes a rush driving mode identifying unit 171 and a fuel-saving driving mode identifying unit 172.
The system controller 160 has, for example, a circuit configuration mainly including a microprocessor, and the system controller 160 comprehensively manages the above-described units and appropriately controls the operation timing of the entire system.
In order to control these timings and execute calculations related to fuel consumption, a circuit unit that functions as a clock signal generation unit and a timer is included as usual.

Each unit described above fulfills its original function through a cooperative operation with the system controller 160.
Of the above-described units, the reference fuel consumption information / best fuel consumption information holding unit 120 includes a functional unit as a reference fuel consumption information holding unit 121 and a functional unit as a best fuel consumption information holding unit 122, which will be described later.
The travel time reduction / delay information generation unit 180 includes a travel time reduction information generation unit 181 and a functional unit as the travel time delay information generation unit 182.
In such a system, the reference travel time information holding unit 110 is a reference travel time information that represents an assumed reference travel time required for travel in an arbitrary travel section that can be selected by the user from outside the system. Is a functional unit that holds

The reference movement time information holding unit 110 holds reference movement time information. For this holding, a configuration including an appropriate storage element such as an EEPROM is employed.
In addition, the reference fuel consumption information holding unit 121 of the reference fuel consumption information / best fuel consumption information holding unit 120 holds reference fuel consumption information representing the assumed reference fuel consumption in the travel of the travel section described above.
This reference fuel consumption information holding unit 121 holds reference fuel consumption information. For this holding, a configuration including an appropriate storage element such as an EEPROM is employed.

Furthermore, the travel time information acquisition unit 130 acquires travel time information representing the actual time required for the travel of the travel section described above. This travel time information is acquired as a time difference between the time when the point that becomes the start point of the travel section described above is issued and the time when the point that reaches the end point of the travel section is reached.
Moreover, the fuel consumption information acquisition unit 140 acquires fuel consumption information representing the actual fuel consumption in the movement of the travel section described above. This fuel consumption information includes the fuel consumption data from the detection function unit provided in the vehicle to detect the fuel consumption, and the movement from the detection function unit provided in the vehicle to detect the movement distance corresponding to the fuel consumption. Obtained by calculation based on distance data.

On the other hand, the fuel consumption information providing unit 150 includes the reference travel time information by the reference travel time information holding unit 110, the reference fuel consumption information by the reference fuel consumption information holding unit 120, the travel time information by the travel time information acquisition unit 130, and the fuel consumption information acquisition unit. The fuel consumption information according to 140 is provided to the user.
In this provision, the travel time information may be provided as information representing an event having a certain correlation with the data instead of or along with the data of the travel time itself.

For example, the fuel consumption information is provided on the display unit provided in the vehicle in a state in which each information is displayed in a state that allows comparison between the information related to the reference and the information related to the acquisition.
In this case, for example, the display unit adopts a mode in which the fuel consumption information is displayed when the movement in the travel section described above is completed and when the operation of the fuel consumption information providing system 100 is finished.

As described above, when the fuel consumption information is displayed when the movement in the travel section is completed or when the operation of the fuel efficiency information providing system 100 is finished, the fuel consumption information is collectively displayed after traveling to some extent. It fits well with user needs such as wanting to check.
In addition, when the operation of the fuel efficiency information providing system 100 is ended, the case where the ignition key is turned off corresponds to this example.

On the other hand, as will be described later, for example, information relating to each information and information relating to acquisition are displayed on a display unit of an information terminal (for example, a personal computer or a portable terminal device) via a communication network including a wireless section. The display is performed in a state that allows comparison between the two.
On the other hand, the rush driving mode identifying unit 171 of the driving mode identifying unit 170 identifies whether or not it corresponds to the “fast driving” mode of rushing compared to the normal driving mode.

In one embodiment of the present invention, the rush driving mode identification unit 171 does not directly depend on a phenomenon from the psychological aspect of the driver, and whether or not the vehicle speed fluctuation is within a predetermined vehicle speed fluctuation range. Based on the above, a simple configuration for identifying whether or not it corresponds to “fast driving” is adopted.
However, the “early driving degree diagnosis” conducted by the Japan Automobile Accident Countermeasures Organization and the driver's psychology as studied by the Japan General Insurance Association, to the degree of “earning first” In response, “fast driving” may be identified.

In addition, the vehicle speed fluctuation | variation range in the above-mentioned is taken as the range of the value prescribed | regulated by the difference with the base vehicle speed (one of the base data which the navigation apparatus demonstrated later with reference to FIG. 2) assumes beforehand, for example.
On the other hand, in another embodiment of the present invention, the urgent driving mode identifying unit 171 of the driving mode identifying unit 170 identifies whether or not it corresponds to “rapid driving” based on the standard deviation of the frequency of the vehicle speed fluctuation. The structure which does is taken.
In yet another embodiment of the present invention, the urgent driving mode identifying unit 171 identifies whether the accelerating / decelerating value corresponds to “early rushing driving” based on whether the magnitude of acceleration / deceleration is greater than a predetermined value. The structure which does is taken.

Of the travel time reduction / delay information generation unit 180 described above, the travel time reduction information generation unit 181 is based on the reference travel time information by the reference travel time information holding unit 110 and the travel time information by the travel time information acquisition unit 130. The travel time shortening information indicating the degree of shortening of the travel time with respect to the reference travel time is acquired.
The acquisition of the travel time shortening information is performed when the rush driving mode identification unit 171 identifies that it corresponds to the “rush driving”, but may be performed at other times.

In the embodiment of the present invention, as described above, it is not left to only the “fast driving” driver's feeling but can be recognized objectively based on a certain standard.
Therefore, it becomes possible to improve the objectivity regarding the awareness of “early driving” and to provide the driver with information having sufficient reliability to contribute to driving for reducing fuel consumption.
Further, the fuel consumption fluctuation information generation unit 190 described above changes the fuel consumption relative to the reference fuel consumption based on the reference fuel consumption information held by the reference fuel consumption information holding unit 120 and the fuel consumption information acquired by the fuel consumption information acquisition unit 140. The fuel consumption fluctuation information representing the degree of the fuel consumption is acquired.

The fuel consumption fluctuation information is quantitative information and is suitable for driving for fuel consumption reduction.
The acquisition of the fuel consumption fluctuation information is performed when the rapid driving mode identifying unit 171 identifies that it corresponds to the “rapid driving”, but may be performed at other times.
In the above description, it has been described that the urgent driving mode identifying unit 171 identifies that it corresponds to “first urgent driving”. However, as described above, in the embodiment of the present invention, the driving mode identifying unit 170 is omitted. A fuel efficiency driving mode identification unit 172 is included.
This fuel-saving driving mode identifying unit 172 identifies whether or not the fuel-saving driving mode is a “fuel-saving driving” mode that prioritizes fuel consumption compared to the normal driving mode.

For example, the identification of whether or not it corresponds to the “fuel-saving driving” is performed based on whether or not the vehicle speed fluctuation is within a predetermined vehicle speed fluctuation range.
The vehicle speed fluctuation range in this case is also set to a value defined by a difference from a base vehicle speed assumed in advance, for example.
The fuel-saving driving mode identifying unit 172 employs a configuration that identifies whether or not the fuel-saving driving mode corresponds to “fuel-saving driving” based on the standard deviation of the frequency of vehicle speed fluctuations.

Further, the fuel-saving driving mode identifying unit 172 adopts a configuration for identifying whether or not the fuel-saving driving mode is applicable based on whether the magnitude of acceleration / deceleration is larger than a predetermined value.
Of the travel time reduction / delay information generation unit 180 described above, the travel time delay information generation unit 182 acquires travel time delay information indicating the degree of delay of the travel time with respect to the reference travel time. This acquisition is performed based on the reference movement time information held in the reference movement time information holding unit 110 and the movement time information acquired by the movement time information acquisition unit 130.

The acquisition of the travel time delay information is performed when the fuel-saving driving mode identifying unit 172 identifies that it corresponds to “fuel-saving driving”, but may be performed at other times.
The fuel consumption fluctuation information generation unit 190 described above is based on the reference fuel consumption information held by the reference fuel consumption information holding unit 120 and the fuel consumption information acquired by the fuel consumption information acquisition unit 140 even in the case of “fuel saving driving”. The fuel consumption fluctuation information indicating the degree of fluctuation of the fuel consumption with respect to the reference fuel consumption is acquired.

The fuel consumption fluctuation information acquired in this way is also provided to the user through the fuel consumption information providing unit 150.
In addition to evaluating “fuel-saving driving” based on a certain standard, it is possible to provide the driver with quantitative data with high objectivity and to impress the results of fuel-saving efforts accordingly.
On the other hand, the best fuel consumption information holding unit 122 of the reference fuel consumption information / best fuel consumption information holding unit 120 holds the best fuel consumption information including data related to the best fuel consumption corresponding to the above-described traveling section.

The best fuel consumption information may include not only data on the best fuel consumption but also information on driving conditions and other various conditions related to the realization of the best fuel consumption.
Such best fuel consumption information is also provided to the user through the fuel consumption information providing unit 150 described above.
It can be expected that the driver will be provided with the best fuel efficiency information to be aware of the degree of achievement of fuel-saving driving at the present time, and become a motivation to perform more appropriate fuel-saving driving.

(Operation of the fuel efficiency information providing system as an embodiment of the present invention)
FIG. 3 is a flowchart showing the operation of the fuel efficiency information providing system (its control device 10) as an embodiment of the present invention described above.
Next, the operation of the fuel efficiency information providing system as the embodiment of the present invention will be described with reference to the flowchart of FIG.
In step S301, it is determined whether or not the vehicle has arrived at the calculation start point that is the start of the travel section for which fuel consumption is to be measured, and the vehicle waits for this point (step S301: No).

  In step S302, in response to the determination that the vehicle has reached the above-described calculation start point in step S301 (step S301: Yes), the fuel consumption amount detection unit 211 performs based on the estimated vehicle speed using the vehicle speed sensor 260. Integration of the detected fuel consumption in the engine 220 is started by the control device 10. In parallel with the execution of the integration, the time measurement operation in the travel time information acquisition unit 130 in FIG. 1 in the control device 10 in FIG. 2 is advanced to acquire the travel time for each section. The fuel consumption information acquisition unit 140 in the control unit 10 continues the calculation of fuel consumption based on the travel time for each section acquired in this way and the integrated value of the above-described fuel consumption corresponding thereto. While continuing this calculation, it is monitored whether or not the end of the scheduled travel section set in the navigation device 270 has been reached, that is, whether or not the movement of the specified section has been completed (step S303). As long as it is not completed (step S303: No), the calculation is further continued.

In step S304, in response to the determination that the movement of the specified section has been completed (step S303: Yes), the fuel consumption data (fuel consumption information) as the final calculation result is used as the reference movement in the control device 10 (FIG. 2). Comparison is made with the reference travel time and reference fuel consumption information held in the time information holding unit 110 and the reference fuel consumption information holding unit 121 (FIG. 1).
In this embodiment, along with such a comparison, whether or not the driving mode of the vehicle in the above-mentioned traveling section corresponds to the “fast driving” in which the driving mode is faster than the normal driving mode. Identify.

In step S305, it is determined whether or not there is a display request for each information of the reference travel time and the reference fuel consumption, the comparison result, and the identification result of the driving mode.
In step S306, in response to the determination that there is a display request (step S305: Yes), the comparison result and the identification result of the driving mode are displayed. For this display, for example, a superimpose display is displayed on the display of the route guide on the display of the navigation device 270 (FIG. 2).

On the other hand, when it is determined that there is no display request (step S305 :: No), this flow is finished as it is.
As described above, in one embodiment of the present invention, the urgent driving mode identification unit 171 does not directly depend on the phenomenon from the psychological aspect of the driver, and the vehicle speed fluctuation is within a predetermined vehicle speed fluctuation range. A simple configuration is adopted for identifying whether or not it corresponds to “fast driving” based on whether or not the vehicle is in the state.

However, the “early driving degree diagnosis” conducted by the Japan Automobile Accident Countermeasures Organization and the driver's psychology as studied by the Japan General Insurance Association, to the degree of “earning first” In response, “fast driving” may be identified.
Further, it is possible to adopt a configuration for identifying whether or not the vehicle falls under “rapid driving” based on the standard deviation of the frequency of vehicle speed fluctuations.

In addition to identifying whether or not it corresponds to “early driving”, it is configured to identify whether or not it corresponds to “fuel-saving driving” in a mode that prioritizes fuel consumption compared to the normal driving mode. It can also be taken.
The above-described identification is performed by a cooperative operation between the driving mode identification unit 170 (its fuel-saving driving mode identification unit 172) and the system controller 160 (FIG. 1) in the control device 10.

(One method for identifying driving modes)
Next, with reference to the drawings, one of these identification methods will be described.
FIG. 4 is a diagram for explaining one identification method of the driving mode in the driving mode identification unit which is a component of the fuel efficiency information providing system as the embodiment of the present invention.
Is the driving mode identification method in FIG. 4 applicable to “first driving” based on the difference in actual vehicle speed detected by the vehicle speed sensor 260 (FIG. 2) with respect to the base vehicle speed that is the assumed traveling speed? And whether it corresponds to “fuel-saving driving”.
In FIG. 4, the horizontal axis represents the above-described base vehicle speed, and the vertical axis represents the difference between the actual vehicle speed and the above-described base vehicle speed. The straight line S41 in the region where the difference value is positive is the determination threshold value for “early driving”, and the straight line S42 in the region where the difference value is negative is the determination threshold value for “fuel-saving operation”.

The driving mode identification unit 170 and the system controller 160 (FIG. 1) in the control device 10 are used to compare the data relating to the identification criteria of FIG. 4 that is held in advance with the actual driving state data acquired from the vehicle speed sensor 260. Based on this, the determination of “fast driving” or “fuel-saving driving” is executed.
When the driving mode is identified as described above, the driving tendency can be objectively evaluated on a uniform basis according to the degree of deviation of the actual vehicle speed from the base vehicle speed. It is possible to provide an accurate indicator for

(Other methods for identifying driving modes)
FIG. 5 is a diagram for explaining another method of identifying the driving mode in the driving mode identifying unit.
Whether the driving mode identification method of FIG. 5 corresponds to “fast driving” based on the standard deviation magnitude of the actual vehicle speed fluctuation frequency detected by the vehicle speed sensor 260 (FIG. 2), and It is a method of identifying whether or not it corresponds to “fuel-saving driving”.
In FIG. 5, the horizontal axis represents the above-described base vehicle speed, and the vertical axis represents the standard deviation of the actual vehicle speed fluctuation frequency. For this standard deviation, the straight line S51 in the region above the horizontal axis is the determination threshold for “early driving”, and the straight line S52 in the region below the horizontal axis is the determination threshold for “fuel-saving operation”.

As can be seen from FIG. 5, in a region where the base vehicle speed is low, a determination threshold is set so as to make the determination sensitivity dull so as not to make a mistake in identification.
The driving mode identification unit 170 and the system controller 160 (FIG. 1) in the control device 10 are used to compare the data relating to the identification criteria of FIG. 5 that is held in advance with the actual driving state data acquired from the vehicle speed sensor 260. Based on this, the determination of “fast driving” or “fuel-saving driving” is executed.

When the driving mode is identified as described above, the driving tendency can be objectively evaluated on the basis of the standard deviation based on the standard deviation of the fluctuation frequency of the actual vehicle speed. It is possible to provide an accurate indicator for
Further, since the tendency of the determination result to be influenced by the temporarily protruding vehicle speed data can be reduced as compared with the method of FIG. 4, the validity of the evaluation can be enhanced.

(Example of fuel consumption information display)
FIG. 6 shows a display example when information such as driving mode and fuel consumption is provided to the user in such a form that the standard (ideal) driving value and the actual driving value are compared and displayed. FIG.
The display in step S306 in the flowchart of FIG. 3 can also take the form illustrated in FIG.
In the display items illustrated in FIG. 6, “actually measured values” are data corresponding to actual driving results collected and calculated in the control unit 10 as described above.
The “ideal value” is data in a virtual running state with reference to the base data.

Furthermore, the “best data” is the best data determined in consideration of the performance of other vehicles related to the same travel section.
In the “actual measurement value” column, not only the above-described data but also a determination result of “early driving” or “fuel-saving driving” as described above is displayed.
The display in the form of FIG. 6 takes a form of superimposing the route guide on the display of the navigation device 270 (FIG. 2), for example.
In addition, the personal computer 22 and the cellular phone 23 described with reference to FIG.
