The road type information shown is collected, and the fuel efficiency information of the vehicle 2 is collected from the engine ECU 12.

  The second information collection unit 34B collects operation information regarding the driving operation of the vehicle 2 that affects the fuel consumption of the vehicle 2 from the accelerator pedal sensor 14, the brake pedal sensor 16, the shift position sensor 18, and the vehicle speed sensor 20.

The storage unit 34C stores the collected travel information, the collected fuel consumption information, and the collected operation information in the information providing database 26 in association with each other.
Specifically, the travel information (road type information), fuel consumption information, operation information, and travel information (route information, section information) collected by the first information collection unit 34A read from the information collection data table 26A are used. The latest data table 26B and the past data table 26C are created and updated based on the information generated by the statistical processing.

The specifying unit 34D specifies from the past data table 26C fuel efficiency information corresponding to past travel information that is the same as or similar to the latest travel information collected by the first information collecting unit 34A and stored in the latest data table 26B. It is.

The evaluation means 34E evaluates the latest fuel consumption information (fuel consumption) based on the comparison result between the identified past fuel consumption information and the collected latest fuel consumption information.
The evaluation unit 34E evaluates the latest operation information (driving operation) based on the comparison result between the identified past operation information and the collected latest operation information.

  The notification unit 34F notifies the driver of the latest fuel efficiency information evaluation result and the latest operation information evaluation result using the display unit 30 or the voice unit 32.

Next, the operation of the vehicle information providing apparatus 10 will be described with reference to the flowchart of FIG.
When the vehicle 2 travels in a state where the vehicle information providing apparatus 10 is activated, the process of FIG. 5 is started.
First, the information providing ECU 34 collects travel information (time information, position information, road type information) and operation information (accelerator opening information, brake operation amount information, shift position information, vehicle speed information) as shown in FIG. Then, the information is accumulated (updated) in the information collection table 26A (step S10: first information collection means 34A, second information collection means 34B, accumulation means 34C).
Next, the information providing ECU 34 statistically processes the travel information, operation information, and fuel consumption information accumulated in the information collection table 26A, so that the latest data table 26B is obtained as shown in FIGS. Create (steps S12 and S14).

Next, the information providing ECU 34 determines whether there is a past data table 26C corresponding to the latest data table 26B (step S16: specifying unit 34D).
In the present embodiment, the correspondence between the latest data table 26B and the past data table 26C means that the time zones in the latest data table 26B and the past data table 26C match and the paths (sections) match. .

If the determination result in step S16 is negative, the latest data table 26B is created as the past data table 26C (step S18: storage means 34C), and the process ends.
If the determination result in step S16 is affirmative, it is determined whether the latest fuel efficiency E1 in the latest data table 26B is worse than the average fuel efficiency E0 in the past data table 26C by a predetermined value ΔEa (step S20: evaluation means 34E). Here, that the latest fuel efficiency E1 is worse than the average fuel efficiency E0 by a predetermined value ΔEa corresponds to the fact that E1 ≦ E0−ΔEa is satisfied.
In the present embodiment, determination of fuel consumption includes comparison determination of fuel consumption in a route and comparison determination of fuel consumption in each section.
If the determination result in step S20 is affirmative, the latest fuel consumption has deteriorated by a predetermined value ΔEa or more compared to the past fuel consumption, so the driver needs to be aware of energy-saving driving.
Therefore, in the present embodiment, the information providing ECU 34 notifies the driver of the evaluation result of the fuel consumption and the evaluation result of the driving operation by the display unit 30 and the voice unit 32 (step S22: notification unit 34F).
This notification may be performed on the travel of the entire route or may be performed for each section.
For example, as a result of evaluation of fuel consumption, “the route from point A to point D (in the section of the city road from point A to point B), the latest fuel consumption is X km / L. It is 5 km / L worse than the past average fuel consumption. As described above, the latest fuel efficiency information E1 and the difference between the past average fuel efficiency can be notified.
In addition, as a result of the evaluation of the driving operation, “in the route from point A to point D (in the section of the city road from point A to point B), the latest number of brake operations is Y times (the number of accelerator operations). The number of times of brake operation is greater than (the number of times of accelerator operation) is two times ", and the difference between the latest operation information and the past operation information can be notified.
Then, the process ends without performing the process of accumulating and updating the contents of the latest data table 26B in the contents of the past data table 26C.

In addition, the notification form of the evaluation result of the fuel consumption and the evaluation result of the driving operation is not limited to the exemplified form, and various forms are conceivable.
For example, the latest fuel efficiency information E1 and the past average fuel efficiency may be listed and notified as the fuel efficiency evaluation result.
Or, as a result of driving operation evaluation, in addition to the number of times of brake operation and the number of accelerator operations, it is notified that the amount of brake operation per hour, the amount of accelerator operation, the number of shift changes, and the amount of change in vehicle speed exceeded a predetermined value. May be.
In short, what is necessary is just to be able to notify the driver of driving information and operation information that affect fuel consumption, and any form of notification may be used.

If the determination result in step S20 is negative, it is determined whether or not the latest fuel efficiency E1 in the latest data table 26B is better than the average fuel efficiency E0 in the past data table 26C by a predetermined value ΔEb (step S24: evaluation means 34E). Here, the fact that the latest fuel efficiency E1 is better than the average fuel efficiency E0 by a predetermined value ΔEb corresponds to the establishment of E1 ≧ E0 + ΔEb. However, ΔEb may be the same as or different from ΔEa.
If the determination result in step S24 is affirmative, the latest fuel consumption is improved by a predetermined value ΔEb or more compared to the past fuel consumption.
Therefore, in the present embodiment, the information providing ECU 34 notifies the driver of the evaluation result of the fuel consumption and the evaluation result of the driving operation to the driver through the display unit 30 and the voice unit 32 in order to improve the awareness of energy saving driving (step S26). : Notification means 34F).
This notification may be performed for the travel of the entire route, as in step S22, or may be performed for each section.
For example, as a result of evaluation of fuel consumption, the latest fuel consumption is X km / L in the route from point A to point D (in the section of the city road from point A to point B. It is 5 km / L better than the past average fuel consumption. As described above, the latest fuel efficiency information E1 and the difference between the past average fuel efficiency can be notified.
In addition, as a result of the evaluation of the driving operation, “in the route from point A to point D (in the section of the city road from point A to point B), the latest number of brake operations is Y times (the number of accelerator operations). The number of times of brake operation is less than (the number of times of accelerator operation) is two times smaller than the number of times of operation of the accelerator. ”And the difference between the latest operation information and the past operation information can be notified.
The notification form of the evaluation result of the fuel consumption and the evaluation result of the driving operation is not limited to the exemplified form, and various forms are conceivable as in the case of step S22.

Next, a process of accumulating and updating the contents of the latest data table 26B in the contents of the past data table 26C is performed (step S28: accumulating unit 34C), and the process is terminated.
If the determination result in step S24 is negative, step S26 is skipped, step S28 is performed, and the process ends.

In FIG. 5, whether or not the past data table 26 </ b> C is updated is summarized as follows.
1) When the latest fuel consumption is worse than the past fuel consumption by a predetermined value Ea or more, the process of accumulating and updating the contents of the latest data table 26B in the contents of the past data table 26C is not performed.
That is, when the evaluation result of the latest fuel consumption E1 is remarkably bad, the process of accumulating and updating the contents of the latest data table 26B in the contents of the past data table 26C is not performed, so that the average of the past data table 26C is obtained. The fuel efficiency E0 is prevented from decreasing unnecessarily, and the evaluation standard of fuel efficiency is not lowered too much.
2) In the following cases, the contents of the latest data table 26B are accumulated and updated in the contents of the past data table 26C.
2-1) When the latest fuel consumption is improved compared to the past fuel consumption 2-2) When the latest fuel consumption is improved within a range less than the predetermined value Eb compared to the past fuel consumption 2-3 ) When the latest fuel consumption has deteriorated in a range less than the predetermined value Ea as compared with the past fuel consumption. That is, when the evaluation result of the latest fuel consumption E1 is not significantly worse, the contents of the latest data table 26B are stored as past data. By executing the process of accumulating and updating the contents of the table 26C, the average fuel efficiency E0 of the past data table 26C is updated within an appropriate range, and the fuel efficiency evaluation standard is maintained within the appropriate range. .

  In the present embodiment, the fuel efficiency is evaluated using the average fuel efficiency, but it goes without saying that either the best fuel efficiency or both the average fuel efficiency and the best fuel efficiency may be used.

In the present embodiment, the fact that the latest data table 26B and the past data table 26C correspond in step S16 means that the time zones in the latest data table 26B and the past data table 26C match, and the route (section). Was described as a match.
That is, fuel consumption information corresponding to past travel information identical to the latest travel information stored in the latest data table 26B is specified from the past data table 26C.
However, even if the routes (sections) do not match, the latest data table 26B and the past data table 26C may correspond to each other when the time zones match and the road type information matches.
For example, when considering urban roads A and B in different areas, the traveling speed and the degree of congestion are considered to be the same for the urban roads A and B. Therefore, if the past data table 26C obtained on the city road A exists, the fuel efficiency information and the operation information can be evaluated based on the latest data table 26B obtained on the city road B and the past data table 26C. It is.
In this way, past fuel efficiency information and operation information corresponding to similar travel information that does not coincide with the latest collected travel information can be identified from the information providing database. This is advantageous in improving the usability of the vehicle information providing apparatus 10.

As described above, according to the present embodiment, the travel information including the position information of the road on which the vehicle 2 travels and the road type information indicating the type of the road and the fuel consumption information of the vehicle 2 are collected and stored in the database. The past fuel consumption corresponding to the travel information that is the same or similar to the latest travel information collected is identified from the information providing database 26, and the latest fuel consumption is determined based on the comparison result between the past fuel consumption and the latest fuel consumption. The fuel efficiency was evaluated and the evaluation result was notified to the driver.
Therefore, for example, providing an evaluation result that appropriately evaluates the energy consumption rate according to the type of road such as an urban road, a highway, and a mountain road is advantageous in making the energy saving driving more accurate.

  In the present embodiment, the travel information includes time information indicating the time at which the vehicle 2 travels. Therefore, it is possible to evaluate and notify the energy consumption rate in consideration of a traffic jam situation that occurs depending on the time zone. For this reason, it is even more advantageous in raising awareness of energy saving operation more accurately.

  In this embodiment, since the latest operation information is evaluated based on the comparison result between the identified past operation information and the collected latest operation information, and the evaluation result is notified, the energy saving operation is performed. This is advantageous for raising the awareness of the necessary operations.

As described above, when the present invention is applied to an electric vehicle using a motor as a drive source, the energy consumption rate is a power consumption rate (wh / km).
In this case, the information providing ECU 34 may receive power consumption rate information from the ECU that controls the motor and the battery.
