Description

  The present invention relates to an evaluation display system, method and program for displaying an evaluation of fuel consumption of a vehicle.

  Conventionally, various techniques for performing display for improving the fuel efficiency of a vehicle have been developed. For example, in Patent Document 1, the evaluation of fuel consumption in past driving is divided into a plurality of stages (good, intermediate, bad, etc.) and displayed on a map for each point or route, and the current fuel consumption at the current position of the vehicle is displayed. A technique for displaying the evaluation together is disclosed.

JP 2002-350152 A

In the prior art described above, there is a possibility that highly important information may not be reliably transmitted to the driver. That is, a map of a navigation system or the like usually displays various information such as facilities around the road, destinations, and traffic lights in addition to the road. When displaying, the information shown on the map is diverse, and it is difficult for the driver who cannot directly view the map during driving to grasp the contents immediately. In particular, when a driver improves fuel efficiency, it is rare for the driver to require evaluation at all stages, and usually he focuses only on a specific evaluation, such as trying to improve a point with poor evaluation. To drive. Therefore, when all of the evaluations in multiple stages are displayed on the map, it takes time to extract the information required by the driver from the map, and information that is highly important for the driver It is inhibited from being transmitted to the person.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of easily transmitting highly important information to a driver.

  In order to achieve the above object, in the present invention, for each unit section on the map on which the current position of the vehicle is displayed, a current evaluation indicating an evaluation of fuel consumption in the current travel of the vehicle, and a current travel The past evaluation showing the evaluation of the fuel consumption of the vehicle in the past is also displayed. That is, the current evaluation and the past evaluation are displayed on the map so that they can be viewed simultaneously. However, for past evaluations, the evaluation level to be displayed differs depending on whether the vehicle is traveling or not. When the vehicle is traveling, a past evaluation having an evaluation level worse than the predetermined evaluation level is displayed on the map. When the vehicle is not running, past evaluations of all evaluation levels are displayed on the map.

  As a result, during driving, the driver can drive while grasping a past evaluation at an evaluation level worse than a predetermined evaluation in the evaluation of past fuel consumption. When the vehicle is not running, the driver can grasp past evaluations of all evaluation levels. In other words, when the driver improves the fuel efficiency evaluation by improving the driving operation, it is difficult to be aware of the improvement of the driving operation in all the unit sections, and the driving operation is improved in the unit sections where there is no improvement effect. In many cases, attention is distracted and the effects are adversely affected. In order to effectively improve the fuel efficiency evaluation, it is necessary to improve the driving operation in the unit section where the fuel efficiency evaluation is bad. During driving, the driver in the unit section where the fuel efficiency evaluation is bad It is important to be aware that people improve their driving skills. Therefore, if the vehicle is running, a past evaluation with an evaluation level worse than the predetermined evaluation level is displayed on the map (a past evaluation with an evaluation level higher than the predetermined evaluation level is not displayed). This makes it possible to easily transmit highly important information to the driver.

  Here, the map display control means displays a map around the current position along with the current position of the vehicle on the display unit, and also displays the current evaluation and past evaluation for each unit section on the map. When the vehicle is traveling, a past evaluation with an evaluation level worse than the predetermined evaluation level is displayed on the map, and when the vehicle is not traveling, past evaluations of all evaluation levels can be displayed on the map. I can do it. That is, the display unit displays a map showing roads and facilities around the current position of the vehicle, information indicating the current position of the vehicle, current evaluation and past evaluation, and evaluation of past evaluations to be displayed. It is only necessary that the level can be switched depending on the running state of the vehicle. In addition, in this invention, it is comprised so that this evaluation and past evaluation may be displayed for every unit area on a map. The unit section may be a section for deriving the conclusion of the evaluation regarding fuel efficiency, and a section of a certain distance may be used as the unit section, or a section determined by a predetermined rule may be used as the unit section. As the latter, for example, it is possible to adopt a configuration in which one link whose end point is the nearest node indicated by the map information is one unit section. Furthermore, the unit section that is the target for displaying the current evaluation and the unit section that is the target for displaying the past evaluation may be the same or different. That is, it is only necessary that the unit section is determined by a common rule, and the unit section to be displayed may be appropriately selected.

  Further, the map display control means only needs to be able to switch the display object depending on whether the vehicle is traveling or not depending on whether the vehicle is traveling, and a predetermined evaluation that serves as an index for switching the display object. The level only needs to be determined in advance according to the importance that contributes to the improvement of the driver's fuel efficiency evaluation. That is, it is only necessary to set a predetermined evaluation level so that an evaluation level that is assumed to improve the current evaluation by the driver improving the driving operation in the road section is displayed. For example, when the evaluation level has two stages of good evaluation and bad evaluation, the good evaluation is set to a predetermined evaluation level, and bad evaluation worse than the predetermined evaluation level is displayed.

  In addition, about evaluation this time, evaluation of an evaluation level worse than a predetermined evaluation level may be displayed, evaluation of all evaluation levels may be displayed, and it is displayed depending on whether it is running or not. You may switch the evaluation level. For example, if the current evaluation of all evaluation levels is displayed on a map when the vehicle is traveling and when the vehicle is not traveling, the driver can determine whether or not the current traveling performance is good. It is possible to grasp whether or not it is running.

  The current evaluation acquisition means only needs to be able to acquire the current evaluation indicating the evaluation of the fuel consumption in the current travel of the vehicle for each unit section. In other words, it is only necessary to acquire, for each unit section, the current evaluation for at least the section displayed on the map among the current travel section having the current position as the end point. Here, the current travel section is a section where the current position is the end point, and the total distance of the section increases as the vehicle advances. In addition, the starting point of the current travel section is not particularly limited, and when the vehicle continuously travels to the current position, the start point of the continuous travel may be set as the start point of the current travel section, or the travel date may be different. The point where the vehicle existed before reaching the current position in the case of continuous running may be used as the starting point of the section. That is, it is only necessary to define the current travel section so that the current travel and the past travel can be distinguished from each other and compared with each other.

  The past evaluation acquisition unit only needs to be able to acquire a past evaluation that shows the evaluation of the fuel consumption of the vehicle in the past for each unit section rather than the current travel. That is, it is only necessary that the past evaluation can be acquired for the display target section of the past evaluation on the map. Specifically, among the driving sections displayed in the map that are past the current time, the section that should be compared with the current evaluation is set as the display target section of the past evaluation, and the evaluation of the fuel consumption for the display target section is performed for each unit section. You only have to get it. Here, the display target section of the past evaluation may be all or a part of the section in which the information of the past evaluation exists. That is, the past fuel consumption evaluation is regularly specified and recorded on the recording medium, and is a unit section on the road included in the map, and all the past fuel consumption evaluations recorded on the recording medium are recorded. The unit section may be configured to display a past evaluation, or a past evaluation may be displayed by selecting a display target section from a unit section in which a past fuel consumption evaluation is recorded on a recording medium.

  As an example of the configuration in which the display target section is selected from the unit sections whose past fuel consumption evaluations are recorded on the recording medium, the vehicle fuel consumption evaluation when traveling in the section including the current position in the past rather than the current traveling is performed. It is good also as a structure which acquires the past evaluation shown for every unit area. That is, the past evaluation is acquired with the section including the current position as the display target section of the past evaluation. According to this configuration, in a state where the current evaluation before the current position is displayed on the map, the section including the current position becomes the display target of the past evaluation, and the evaluation level to be displayed is switched depending on the traveling state of the vehicle. While displayed on the map. Since the section including the current position includes a road that runs immediately after the current position, the driver recognizes a past evaluation with an evaluation level worse than a predetermined evaluation level existing after the current position. It is possible to operate while comparing the evaluation this time.

  Note that the fuel economy evaluation indicated by the current evaluation and the past evaluation as described above may be information that serves as a guideline for changing the fuel efficiency, and information indicating the fuel economy value (for example, an average value in a unit section). Information), information indicating the result of comparing the standard fuel efficiency with the current or past fuel efficiency (for example, information indicating a relative relationship with the standard fuel efficiency), or improving the fuel efficiency. Information (e.g., information indicating the frequency of driving operations contributing to fuel efficiency improvement) may be used. Of course, for the past evaluation, similarly, the evaluation of the fuel consumption may be information that serves as a guideline for changing the fuel consumption.

  In addition, when the vehicle is traveling from the departure location to the destination, the current evaluation of the section from the departure location to the current position is obtained, and the vehicle is the same point as the departure location in the past than the current travel. It is good also as a structure which acquires the past evaluation in the case of departing from and driving to the same point as the destination. That is, the present evaluation and the past evaluation are displayed when the starting point and the destination are common in the current traveling and the past traveling. According to this configuration, it is possible to provide a guideline for suppressing the total fuel consumption when traveling this time from a certain starting point to another destination as compared to past traveling.

  When the departure point and the destination are the same, the route from the departure point to the destination often has the same or a partial overlap. In this case, since all road sections are the same or partly the same in the current run and the past run, the past evaluation and the current evaluation are displayed on the map, and the vehicle travels from the departure place to the destination. It is possible to easily improve the fuel efficiency at the time. In addition, the departure point and the destination may be points explicitly designated by the driver, or depart from points determined to have departed or arrived based on the operation state of the vehicle. You may employ | adopt the structure made into a ground and a destination. Further, the current destination may be estimated based on, for example, the current travel route, past travel history, and the like.

  Further, the evaluation level of the display target may be specified in consideration of factors other than the running state of the vehicle. For example, when the vehicle is traveling, a unit section in which a past evaluation having an evaluation level worse than a predetermined evaluation level continues for a predetermined number of sections or more is specified, and the past evaluation for the specified unit section is displayed on a map. It is good also as a structure. That is, during traveling, the past evaluation is displayed only when the past evaluation having an evaluation level worse than the predetermined evaluation level continues for a predetermined number of sections or more. If past evaluations with an evaluation level worse than the predetermined evaluation level continue, there is a high possibility that the fuel efficiency has deteriorated due to a common factor, and the fuel efficiency is greatly improved by the driver being aware of the improvement in fuel efficiency. Probability is high. Therefore, if the past evaluation is displayed on the map for unit sections in which past evaluations with an evaluation level worse than the predetermined evaluation level continue for a predetermined number of sections or more, highly important information that contributes to fuel efficiency improvement Can be provided to the driver.

  Furthermore, when the vehicle is running and the scale of the map is a scale for displaying a map of an area having a predetermined area or more on the display unit, a past evaluation having an evaluation level worse than the predetermined evaluation level is displayed on the map. It is good also as a structure displayed on. That is, when the scale of the map is variable, the amount of information to be displayed tends to increase as the map display area becomes wider due to the change in the scale. Therefore, when the past scale is displayed for all the evaluation levels, the scale of the map scale may cause trouble in recognition of the evaluation level when the scale of the map is a scale for displaying a map of an area having a predetermined area or more on the display unit. Is determined in advance. When the map is scaled and the scale of the map is the determined scale, if a past evaluation having an evaluation level worse than a predetermined evaluation level is displayed on the map, a large number of past evaluations are displayed and evaluated. It is possible to prevent the recognition of the level from being hindered.

  Further, when the vehicle is traveling as in the present invention, a past evaluation with an evaluation level worse than a predetermined evaluation level is displayed on the map, and when the vehicle is not traveling, all past evaluations of the evaluation level are displayed. The method of displaying on a map can also be applied as a program or method. In addition, the system, program, and method as described above may be realized as a single device, or may be realized by using components shared with each unit provided in the vehicle when realized by a plurality of devices. It can be assumed and includes various aspects. For example, it is possible to provide a navigation system, method, and program including the above-described devices. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention can be realized as a recording medium for a program for controlling the system. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.

It is a flowchart which shows an evaluation information display process. (4A) (4B) (4C) is a figure which shows the example of the map displayed.

Here, embodiments of the present invention will be described in the following order.
(1) Configuration of navigation terminal:
(2) Evaluation information acquisition process:
(3) Evaluation information display processing:
(4) Other embodiments:

(1) Configuration of navigation terminal:
FIG. 1 is a block diagram showing a configuration of an evaluation display system mounted on a vehicle. In the present embodiment, the evaluation display system is realized by the navigation terminal 10. The navigation terminal 10 includes a control unit 20 that includes a CPU, a RAM, a ROM, and the like, and the control unit 20 can execute a program stored in the ROM. In this embodiment, a navigation program can be executed as one of the programs. The navigation program is a program for causing the control unit 20 to realize a function of displaying a map including the current position of the vehicle on the display unit of the navigation terminal and guiding the driver to the destination. An evaluation display program 21 that displays the evaluation together and switches the evaluation level of the past evaluation to be displayed depending on whether or not the vehicle is running is included.

  The vehicle according to the present embodiment includes a fuel efficiency evaluation lamp ECU 40, a GPS receiver 41, a vehicle speed sensor 42, a gyro sensor 43, and a user I / F unit 44. The GPS receiver 41 receives a radio wave from a GPS satellite and outputs a signal indicating a signal for calculating the current position of the vehicle via an interface (not shown). The control unit 20 acquires this signal and acquires the current position of the vehicle. The vehicle speed sensor 42 outputs a signal corresponding to the rotational speed of the wheels provided in the vehicle. The control unit 20 acquires this signal via an interface (not shown) and acquires the vehicle speed. The gyro sensor 43 detects angular acceleration about turning in the horizontal plane of the vehicle, and outputs a signal corresponding to the direction of the vehicle. The control unit 20 acquires this signal and acquires the traveling direction of the vehicle. The vehicle speed sensor 42, the gyro sensor 43, and the like are used for correcting the current position of the vehicle specified from the output signal of the GPS receiver 41. Further, the current position of the vehicle is appropriately corrected based on the travel locus of the vehicle.

  The fuel efficiency evaluation lamp ECU 40 includes a control circuit for evaluating the fuel efficiency of a running vehicle based on the operation of the vehicle, and is connected to a lamp 40a provided on the instrument panel of the vehicle. In this embodiment, the fuel efficiency evaluation lamp ECU 40 is configured to display information indicating fuel consumption (for example, information specified from a signal for operating the injector, information indicated by the fuel consumption sensor, etc.), output information of the vehicle speed sensor 42, and transmission state. It is determined whether or not the combination with the information indicating the condition matches the condition for suppressing fuel consumption. Various conditions can be defined as the conditions for suppressing the consumed fuel. In this embodiment, the consumed fuel is equal to or less than a predetermined amount, the vehicle speed is equal to or greater than a predetermined threshold, and the transmission Is in a normal state (a state such as a drive mode that is not a state for acceleration with high efficiency such as a sports mode), it is assumed that the condition for suppressing fuel consumption is met.

  The fuel consumption evaluation lamp ECU 40 turns on the lamp 40a when the combination of the information matches the condition for suppressing the fuel consumption. As a result, the driver performs an operation in which the consumed fuel is suppressed when the lamp 40a is lit, and the driver performs an operation in which the consumed fuel is excessively consumed when the lamp 40a is turned off. Judgment can be made. In addition, the fuel efficiency evaluation lamp ECU 40 outputs information indicating that the lamp 40a is lit to the control unit 20 when the lamp 40a is lit. Therefore, the control unit 20 can specify that the lamp 40a is turned on and off based on the information. Further, the fuel efficiency evaluation lamp ECU 40 outputs information indicating the above-described fuel consumption to the control unit 20. The control unit 20 can specify the fuel consumption (km / l) of the vehicle for each position based on the information indicating the consumed fuel.

  The user I / F unit 44 is an interface unit for inputting a driver's instruction and providing various information to the driver. The user I / F unit 44 includes an input unit such as a display unit and a switch (not shown), a switch, a speaker, and the like. Audio output unit. The user I / F unit 44 receives a control signal from the control unit 20 and displays an image for performing various guidance on the touch panel display.

  Map information 30 a is recorded on the recording medium 30. The map information 30a includes node data indicating the position of the node corresponding to the end point of the road on which the vehicle travels, shape interpolation point data indicating the position of the shape interpolation point for specifying the shape of the road between the nodes, the nodes The link data indicating the connection of the link is included. Moreover, in this embodiment, the evaluation information 30b which shows evaluation of the fuel consumption of a vehicle is recorded whenever a vehicle drive | works. The evaluation information 30b is information indicating the rate at which the lamp 40a is lit in the fuel efficiency evaluation target section in the unit section, and the evaluation information 30b is recorded while the destination is set and the vehicle is traveling. Information indicating the destination and the departure place is recorded in association with the evaluation information 30b.

  The control unit 20 displays the map including the current evaluation and the past evaluation on the display unit of the user I / F unit 44 by executing the evaluation display program 21 included in the navigation program. In order to execute this process, the evaluation display program 21 includes a map display control unit 21a, a current evaluation acquisition unit 21b, and a past evaluation acquisition unit 21c.

  The map display control unit 21a displays a map around the current position along with the current position of the vehicle on the display unit of the user I / F unit 44, and combines the current evaluation and past evaluation for each unit section on the map. The program module causes the control unit 20 to realize a function of switching the evaluation level of the past evaluation to be displayed depending on whether or not the vehicle is running. That is, the control unit 20 specifies the current position of the vehicle based on the output signals of the GPS receiving unit 41, the vehicle speed sensor 42, and the gyro sensor 43, specifies the display range of the map around the current position of the vehicle, and displays the display range. Information on roads, facilities, etc. is extracted from the map information 30a. Then, the control unit 20 outputs a control signal for drawing a map indicating the current position of the vehicle and roads and facilities around the current position to the display unit of the user I / F unit 44. As a result, the display unit of the user I / F unit 44 displays a map showing roads and facilities around the current position of the vehicle, and the current position of the vehicle.

  The current evaluation acquisition unit 21b realizes the control unit 20 with a function of acquiring the current evaluation that indicates the evaluation of the fuel consumption in the current travel of the vehicle for each unit section (in the present embodiment, a section of a constant distance (for example, 100 m)). This is a program module to be executed. In addition, the control part 20 performs the evaluation information acquisition process mentioned later by this time evaluation acquisition part 21b in the process in which a vehicle drive | works, acquires the lighting rate for every unit area of the lamp 40a, and calculates the lighting rate for the said unit area. Recorded as evaluation information 30b. A current evaluation and a past evaluation are generated from the evaluation information 30b.

  In the present embodiment, the driver operates the user I / F unit 44 by the function of the navigation program to set the destination, and the current position of the vehicle at the time of setting the destination is set as the starting point. Search and guide the route from the starting point to the destination. If the vehicle is currently traveling from the departure point to the destination, the traveling from the departure point to the destination is regarded as the current traveling. That is, the section traveled this time is a section where the starting point is the starting point and the current position is the end point, and the total distance of the section that traveled this time is increased until the vehicle reaches the destination as the vehicle travels. Note that when the destination is set and the vehicle reaches the destination, the control unit 20 records the evaluation information 30b for each unit section from the departure point to the destination. The evaluation information is recorded in association with the departure place and the destination.

  And the control part 20 acquires the evaluation regarding this driving | running | working from this evaluation information 30b as this evaluation by the process of this evaluation acquisition part 21b. For this purpose, the control unit 20 acquires evaluation information 30b for each unit section in the section in which the vehicle has traveled this time before reaching the destination after the start of traveling of the vehicle at the departure place. Then, the control unit 20 compares the lighting ratio of the lamp 40a for each unit section indicated by the evaluation information 30b (the ratio of the distance traveled in the state where the lamp 40a is lit) with a predetermined threshold, and is equal to or higher than the predetermined threshold. In some cases, the fuel economy is evaluated as “good”, and when the lighting ratio is smaller than a predetermined threshold, the fuel efficiency is evaluated as “bad”. That is, in this embodiment, the higher the lighting ratio of the lamp 40a, the higher the fuel consumption. Therefore, the lighting ratio of the lamp 40a corresponds to the frequency of driving operations that contribute to the improvement of the fuel consumption. The presence or absence of a driving operation for improvement can be evaluated. Note that the predetermined threshold only needs to be determined when the fuel efficiency is evaluated, and in the present embodiment, the predetermined threshold is set according to the diagnostic difficulty set in advance by the driver. That is, the predetermined threshold is set to be larger as the diagnosis difficulty level is higher.

  Further, in the present embodiment, the control unit 20 acquires the current average fuel consumption indicating the average fuel consumption of the vehicle in the current travel by the processing of the current evaluation acquisition unit 21b. That is, when traveling with the destination set is performed, the control unit 20 determines the fuel consumption of the vehicle for each position based on the information indicating the fuel consumption from the departure point to the current position when recording the evaluation information 30b. The fuel consumption averaged with respect to the combination of the starting point and the destination is recorded in association with each other.

  The past evaluation acquisition unit 21c is a program module that causes the control unit 20 to realize a function of acquiring a past evaluation indicating, for each unit section, the evaluation of the fuel consumption of the vehicle in the past travel than the current travel. In the present embodiment, the control unit 20 becomes a display target of past evaluation when a vehicle departs from the same point as the departure point in the past and travels to the same point as the destination. Considered past driving. And the control part 20 acquires the evaluation for every unit area of the area which the vehicle drive | worked by the past driving | running | working as a past evaluation.

  For this purpose, the control unit 20 acquires information indicating the lighting ratio of the lamp 40a associated with the same starting point and destination as the above-described current traveling from the evaluation information 30b. In addition, when a plurality of pieces of information in which the same starting point and destination are associated with each other are recorded, for example, the average fuel consumption associated with the starting point and the destination is the best. What is necessary is just to set it as the structure which acquires (that is, the thing with the highest average fuel consumption in the past) as a past evaluation. Then, the control unit 20 compares the lighting ratio of the lamp 40a with a predetermined threshold value. When the lighting ratio is equal to or higher than the predetermined threshold value, the fuel consumption evaluation level is “good”, and when the lighting ratio is smaller than the predetermined threshold value, The evaluation level is “evil”. In addition, in order to determine whether the starting point and the destination are the same for the current driving and the past driving, a predetermined margin is provided for the distance from the point. For example, two points within a distance of 300 m A configuration that is regarded as the same can be adopted.

  When the current evaluation and the past evaluation are acquired as described above, the control unit 20 generates a control signal for rendering the current evaluation and the past evaluation on the map by the process of the map display control unit 21a. / F unit 44 outputs to the display unit. In order to display the current evaluation and the past evaluation, the control unit 20 travels from the map currently displayed on the display unit of the user I / F unit 44 by the section traveled by the current travel and the past travel. Are extracted. And the control part 20 specifies this time evaluation and past evaluation for every unit area in each area.

  When the vehicle is traveling, the control unit 20 displays a past evaluation with an evaluation level worse than a predetermined evaluation level on the map, and when the vehicle is not traveling, all the evaluation levels of past evaluation are displayed. A control signal is output to the user I / F unit 44 so as to be displayed on the map. That is, the control unit 20 determines whether or not the vehicle is currently traveling based on the output signal of the vehicle speed sensor 42 (whether or not the current speed is greater than or equal to a predetermined threshold (for example, 4 km / h)). . When it is determined that the vehicle is traveling, the control unit 20 sets “bad” evaluation as a display target and does not set “good” evaluation as a display target. When it is not determined that the vehicle is traveling, the control unit 20 sets both “bad” evaluation and “good” evaluation as display targets. Then, a control signal for drawing the past evaluation of the display target on the map is output to the display unit of the user I / F unit 44.

  On the other hand, the control unit 20 controls the user I / F unit 44 so that the current evaluations of all evaluation levels are displayed on the map both when the vehicle is traveling and when the vehicle is not traveling. Output a signal. As a result, the display unit of the user I / F unit 44 displays the current evaluation of all evaluation levels for each unit section, and the past evaluation of “bad” evaluation during traveling, and “bad” when not traveling. The past evaluation of both the evaluation and the “good” evaluation is displayed.

  FIG. 4A shows an example of a map displayed on the display unit when traveling, and FIG. 4B shows an example of a map displayed on the display unit when not traveling. In these examples, an icon C indicating the current position of the vehicle is displayed on the road R indicated by the solid curve. In the example shown in FIGS. 4A and 4B, the fuel efficiency evaluation is displayed by an icon imitating a leaf on the road, and the current evaluation of “good” by a solid line icon Etg, and an icon with a solid line hatch. The current evaluation of “bad” is indicated by Etb, the past evaluation of “good” is indicated by the broken line icon Epg, and the past evaluation of “evil” is indicated by the icon Epb with a broken line hatch. 4A is a map displayed when the vehicle is traveling, the icon Epg is not displayed and the icon Epb is displayed. FIG. 4B is a map displayed when the vehicle is not traveling, and the icon Epg, Both Epb are displayed. In addition, the thick line described on the road R has shown the driving | running | working driving | running route | path for reaching from the departure place to the destination in this driving | running | working.

  As described above, according to the present embodiment, the current evaluation and the past evaluation are displayed on the map displayed on the display unit of the user I / F unit 44 so as to be visible at the same time. Furthermore, when the vehicle is traveling, the display target of the past evaluation is limited to “bad” evaluation, and when the vehicle is not traveling, the display target of the past evaluation is both “bad” evaluation and “good” evaluation. . As a result, the driver can drive while traveling while comparing the evaluation of the fuel consumption in the current travel section with the evaluation of the fuel consumption that has been set to the “bad” level in the past. Further, when the vehicle is not running, the driver can grasp past evaluations of all evaluation levels.

  When the driver improves the fuel efficiency evaluation by improving the driving operation, it is difficult to be aware of the improvement of the driving operation in all road sections, and the driver is conscious of improving the driving operation in the road sections where there is no improvement effect. This often distracts and is counterproductive. For example, in FIG. 4B, it is difficult to be aware of improvement in driving operation for all the unit sections corresponding to the “good” evaluation indicated by the icon Epg and the “bad” evaluation indicated by the icon Epb. In addition, there is a case where there is no room for improvement even if an attempt is made to improve the driving operation in the unit section corresponding to the “good” evaluation indicated by the icon Epg.

  On the other hand, there is room for improvement in fuel consumption by improving the driving operation in the unit section corresponding to the “bad” evaluation indicated by the icon Epb. Therefore, in order to improve the evaluation of fuel consumption in this driving, it is necessary to improve the driving operation in the unit section where the past evaluation was “bad”, and the past evaluation is “bad” during driving. It is important that the driver is conscious of improving his / her driving operation in the unit section that was evaluated. In the present embodiment, a map as shown in FIG. 4A is displayed during traveling, the “good” evaluation indicated by the icon Epg is not displayed, and the “bad” evaluation indicated by the icon Epb is displayed. Therefore, it is possible to easily transmit to the driver the unit section in which the past evaluation, which is highly important information for improving the fuel efficiency, is “bad” evaluation.

  Note that when the vehicle is not running, a past evaluation that is a “good” evaluation is also displayed, so the driver can determine whether the “good” or “bad” evaluation is displayed continuously. It is possible to grasp the route traveled in the past travel and the route having the past evaluation. Furthermore, in the present embodiment, as in the example shown in FIGS. 4A and 4B, the current evaluation and the past evaluation are displayed on the map in different aspects (solid line and broken line), so that the driver can evaluate the current evaluation and the past evaluation. Can be clearly distinguished without confusion. Of course, in the section where the current evaluation is displayed (the section behind the current position of the vehicle), the display of the past evaluation is erased, and the current evaluation and the past evaluation are clearly distinguished. May be.

  When the starting point and the destination are the same for the current traveling and the past traveling, the same route is usually searched by the navigation program. When the current travel and the past travel are the same route, as shown in FIG. 4A, the current evaluation Etg and Etb regarding the current travel are displayed for the route from the departure place to the current position. Therefore, if the past evaluation for the unit section behind the current position of the vehicle is deleted on the same route, the past evaluation is displayed ahead of the current position, and the past evaluation is displayed behind the current position. It is possible to make a distinction between the two. In addition, while traveling, it is easy to know what evaluation this time was after traveling in a unit section that had been evaluated as “bad” in the past, and whether fuel efficiency has improved easily. It is possible to judge.

(2) Evaluation information acquisition process:
Next, the evaluation information acquisition process will be described in detail. FIG. 2 is a flowchart of the evaluation information acquisition process. In the present embodiment, the control unit 20 executes the evaluation information acquisition process by the current evaluation acquisition unit 21b after the start of travel with the destination set. Before the evaluation information acquisition process is executed, the control unit 20 evaluates the total distance for determining whether or not the vehicle has traveled a certain distance defined as the length of the unit section, and the evaluation of fuel consumption within the unit section. The variables indicating the evaluation distance for specifying the distance that can be performed and the lighting distance for specifying the distance traveled while the lamp 40a is lit are initialized.

  The control unit 20 adds the travel distance to the cumulative distance (step S100). In the present embodiment, steps S100 to S130 are a loop process, and when the loop process is repeated, the process of step S100 is performed every certain period (for example, 100 ms). Therefore, based on the output signals from the GPS receiver 41, the vehicle speed sensor 42, and the gyro sensor 43, the control unit 20 travels from the previous step S100 to the current step S100. The travel distance ΔL is specified and added to the cumulative distance. That is, the control unit 20 performs an addition process so that a value indicating the total distance traveled by the vehicle while the steps S100 to S130 are repeated becomes the cumulative distance.

  Next, the control unit 20 determines whether or not the vehicle speed is equal to or higher than a predetermined value (step S110). If it is not determined that the vehicle speed is equal to or higher than the predetermined value, steps S115 to S125 are skipped. On the other hand, when it is determined in step S110 that the vehicle speed is equal to or higher than the predetermined value, the control unit 20 adds the travel distance to the evaluation distance (step S115). That is, the above-mentioned traveling distance ΔL added to the cumulative distance in step S100 is added to the evaluation distance.

  Here, the predetermined value as the determination condition in the determination in step S110 is defined in advance as a vehicle speed value (for example, 4 km / h) that makes it impossible to evaluate the fuel efficiency significantly when the vehicle speed is lower than the predetermined value. Just do it. In other words, when the vehicle speed is excessively low, it is difficult to distinguish between driving with reduced fuel consumption and driving with excessive fuel consumption. Does not evaluate fuel economy. For this reason, in this embodiment, when the vehicle speed is lower than the predetermined value, it is regarded that the significant fuel consumption cannot be evaluated, and step S115 is not executed. However, if the vehicle speed is equal to or higher than the predetermined value, the significant fuel consumption evaluation is performed. In step S115, the evaluation distance is increased by ΔL. The predetermined value may be the same as the predetermined threshold set for the vehicle speed as one of the conditions when the fuel efficiency evaluation lamp ECU 40 lights the lamp 40a.

  Further, the control unit 20 determines whether or not the lamp 40a is lit (step S120), and skips step S125 if it is not determined that the lamp 40a is lit. On the other hand, when it is determined in step S120 that the lamp 40a is lit, the control unit 20 adds the travel distance to the lighting distance (step S125). That is, when it is possible to perform a significant fuel efficiency evaluation and the lamp 40a is lit, the control unit 20 uses the travel distance ΔL added to the cumulative distance in step S100. Add to the evaluation distance.

  Next, the control unit 20 determines whether or not the cumulative distance is equal to or greater than a certain distance (step S130), and performs the processing after step S100 until it is determined in step S130 that the cumulative distance is equal to or greater than the certain distance. repeat. That is, the control unit 20 determines that the vehicle has traveled the unit section when the cumulative distance is equal to or greater than a predetermined distance defined as the distance of the unit section, and exits the loop process of steps S100 to S130. Become.

  When it is determined in step S130 that the cumulative distance is equal to or greater than the predetermined distance, the control unit 20 determines whether or not the evaluation distance is greater than 0 (step S135). That is, it is determined whether or not there is a section in which significant evaluation can be performed in the process in which the vehicle travels in the unit section. When it is determined in step S135 that the evaluation distance is greater than 0, the control unit 20 sets the lighting ratio of the lamp 40a to the lighting distance / evaluation distance (step S140). On the other hand, when it is not determined in step S135 that the evaluation distance is greater than 0, the control unit 20 sets the lighting ratio of the lamp 40a to 0 (step S145). That is, when the denominator for evaluating the lighting ratio is not 0, the lighting ratio is calculated based on the lighting distance and the evaluation distance, and when the denominator for evaluating the lighting ratio is 0, the lighting ratio is defined. Since the lighting ratio cannot be calculated from Of course, it is also possible to make the evaluation impossible.

  Next, the control unit 20 records the lighting ratio of the lamp 40a set in step S140 or S145 in the recording medium 30 as the evaluation information 30b in association with the unit section for which the cumulative distance is to be measured (step S150). . According to the above processing, the evaluation information 30b for each unit section can be recorded on the recording medium 30. When the evaluation information acquisition process is executed with the vehicle destination set, in step S150, the control unit 20 records information indicating the destination and the departure point in association with the evaluation information 30b. .

(3) Evaluation information display processing:
Next, the evaluation information display process will be described in detail. FIG. 3 is a flowchart of the evaluation information display process. In the present embodiment, the destination is set by the driver, and the past starting point and the destination that are the same as the starting point and the destination of the current travel are past. The evaluation information display process is executed when the evaluation information 30b regarding travel exists. Moreover, the control part 20 is updating the map display for every predetermined period in the display part of the user I / F part 44, and the said evaluation information display process is performed for every said update. Furthermore, before the evaluation information display process is executed, the above-described diagnosis difficulty level is specified in advance by a driver's instruction, a default value, or a travel difficulty level in each unit section.

  Steps S200 to S230 are loop processing for displaying past evaluations on a map, and the control unit 20 first determines whether or not past evaluations should be displayed by the processing of the map display control unit 21a and the past evaluation acquisition unit 21c. A processing target unit section is selected from the determination target sections to be determined (step S200). That is, the control unit 20 specifies the range of the map displayed on the display unit of the user I / F unit 44 by the process of the map display control unit 21a. Further, the control unit 20 performs the process of the past evaluation acquisition unit 21c to change the starting point and the destination from the evaluation information 30b in which the same starting point and destination as the starting point and destination in the current travel are associated. The associated averaged fuel consumption is extracted. Further, the control unit 20 is included in the range of the map displayed on the display unit of the user I / F unit 44 from the unit section associated with the extracted evaluation information 30b by the processing of the map display control unit 21a. A unit section is extracted and specified as a determination target section that is a target for determining whether or not to display a past evaluation. Then, from among the determination target sections, a unit section that is not subjected to the process of determining whether or not the past evaluation should be displayed in steps S205 to S225 described later is selected as the processing target unit section.

  Next, the control unit 20 acquires the past evaluation information of the unit section to be processed by the process of the past evaluation acquisition unit 21c (step S205). That is, the lighting ratio of the lamp 40a in the past travel of the unit section to be processed is acquired. Next, the control unit 20 determines whether or not the lighting ratio of the lamp 40a in the past travel of the unit section to be processed is equal to or greater than a predetermined threshold by the process of the past evaluation acquisition unit 21c (step S210). When it is determined in step S210 that the lighting ratio of the lamp 40a is equal to or higher than the predetermined threshold, the control unit 20 sets the evaluation level of the past evaluation of the unit section to be processed to “good” by the processing of the past evaluation acquisition unit 21c. Set to evaluation (step S215).

  On the other hand, if it is not determined in step S210 that the lighting ratio of the lamp 40a is equal to or greater than the predetermined threshold, the control unit 20 sets the evaluation level of the past evaluation of the unit section to be processed to “bad” by the processing of the past evaluation acquisition unit 21c. Is set to evaluation (step S220). In addition, the predetermined threshold value compared with the lighting ratio of the lamp 40a is set according to the above-mentioned diagnosis difficulty level, and becomes a larger value as the diagnosis difficulty level is higher. Therefore, the higher the diagnosis difficulty level, the more difficult the past evaluation is to be “good”.

  When the evaluation level of the past evaluation is set to “good” evaluation in step S215, the control unit 20 determines whether or not the vehicle is traveling by the process of the map display control unit 21a (step S223). . That is, the control unit 20 determines that the vehicle is running when the current speed of the vehicle is equal to or less than a predetermined threshold (for example, 4 km / h) based on the output signal of the vehicle speed sensor 42. When the evaluation level of the past evaluation is set to “bad” evaluation in step S220, step S223 is skipped and step S225 is executed.

  In addition, step S223 is performed through step S215, and step S225 is also executed when it is not determined in step S223 that the vehicle is traveling. In step S225, the control unit 20 displays the past evaluation of the unit section to be processed by the process of the map display control unit 21a (step S225). That is, the control unit 20 outputs a signal for drawing an icon corresponding to the past evaluation of the unit interval to be processed to the display unit of the user I / F unit 44. The display unit of the user I / F unit 44 displays an icon corresponding to the past evaluation of the unit section to be processed. As a result, when the past evaluation of the processing target unit section is “bad” evaluation, the past evaluation is displayed in the processing target unit section regardless of the running state of the vehicle. Further, when the past evaluation of the processing target unit section is “good” evaluation and the vehicle is not traveling, the past evaluation is displayed in the processing target unit section.

  On the other hand, when it is determined in step S223 that the vehicle is traveling, the control unit 20 skips step S225. Therefore, when the past evaluation of the unit section is “good” evaluation and the vehicle is traveling, the past evaluation of the unit section to be processed is not displayed.

  Next, the control unit 20 determines whether or not the past evaluation is to be displayed for all of the determination target sections by the processing of the map display control unit 21a (step S230). If it is not determined in step S230 that it has been determined whether the past evaluation should be displayed for all of the determination target sections, the control unit 20 repeats the processes in and after step S200. On the other hand, when it is determined in step S230 that it has been determined whether or not past evaluation should be displayed for all of the determination target sections, processing for displaying the current evaluation is performed in step S235 and subsequent steps. As described above, it is determined whether or not the past evaluation should be displayed. When it is determined that the past evaluation is to be displayed, the solid line shown in FIG. The icons Etg and Etb (icons indicating the current evaluation) are not displayed, and the icons Epg and Epb (icons indicating the past evaluation) indicated by broken lines are displayed. In addition, when the route is the same for the current travel and the past travel, the past evaluation is also displayed in the unit section behind the current position of the vehicle. However, the processing after step S235 is performed on the same unit section. When the current evaluation is displayed, the current evaluation is preferentially displayed.

  Steps S235 to S265 are loop processing for displaying the current evaluation on a map. The control unit 20 first performs processing from the display target of the current evaluation to the processing target by the processing of the map display control unit 21a and the current evaluation acquisition unit 21b. Is selected (step S235). That is, the control unit 20 specifies the range of the map displayed on the display unit of the user I / F unit 44 by the process of the map display control unit 21a. Further, the control unit 20 displays on the display unit of the user I / F unit 44 from the unit section associated with the evaluation information 30b recorded on the recording medium in the course of the current run by the process of the current evaluation acquisition unit 21b. A unit section included in the range of the map being specified is specified as a display target. Then, a unit section for which the process for displaying the current evaluation is not performed is selected from the unit sections to be displayed as the unit section to be processed.

  Next, the control unit 20 acquires the current evaluation information of the unit section to be processed by the process of the current evaluation acquisition unit 21b (step S240). That is, the lighting ratio of the lamp 40a in the current travel of the unit section to be processed is acquired. Next, the control unit 20 determines whether or not the lighting ratio of the lamp 40a in the current travel of the unit section to be processed is greater than or equal to a predetermined threshold by the processing of the current evaluation acquisition unit 21b (step S245). When it is determined in step S245 that the lighting ratio of the lamp 40a is equal to or greater than the predetermined threshold, the control unit 20 sets the current evaluation of the unit section to be processed to “good” by the processing of the current evaluation acquisition unit 21b. (Step S250). If it is not determined in step S245 that the lighting ratio of the lamp 40a is equal to or greater than the predetermined threshold value, the control unit 20 sets the current evaluation of the processing target unit section to “bad” by the processing of the current evaluation acquisition unit 21b. (Step S255). The predetermined threshold compared with the lighting ratio of the lamp 40a is the same as the predetermined threshold in step S210.

  Next, the control unit 20 displays the current evaluation of the unit section to be processed by the process of the map display control unit 21a (step S260). That is, the control unit 20 outputs a signal for drawing an icon corresponding to the current evaluation of the unit interval to be processed to the unit interval to the display unit of the user I / F unit 44. As a result, the display unit of the user I / F unit 44 displays an icon corresponding to the current evaluation of the unit section to be processed.

  Next, the control unit 20 determines whether or not the current evaluation of the unit section to be displayed has been displayed by the process of the map display control unit 21a (step S265). That is, the control unit 20 determines whether or not the current evaluation has been displayed for all of the display target unit sections identified in step S235. If it is not determined in step S265 that the current evaluation of the unit section to be displayed has been displayed, the processes in and after step S235 are repeated. On the other hand, when it is determined in step S265 that the current evaluation of the unit section to be displayed has been displayed, the control unit 20 ends the evaluation information display process. In the present embodiment, when the current evaluation is displayed on the same unit section, the current evaluation is preferentially displayed. Therefore, when the current evaluation of the unit section to be displayed is displayed, it is shown in FIG. 4A. As in the example, the evaluation icons Etg and Etb are displayed with solid lines in the section where the vehicle traveled before the current position of the vehicle. In the processing of steps S235 to S265, since the current evaluation is not displayed in a section ahead of the current position of the vehicle, a broken line indicates that the vehicle is traveling in a section ahead of the current position of the vehicle. Past evaluation icons Epb are displayed, and past evaluation icons Epg and Epb are displayed by broken lines when the vehicle is not running.

(4) Other embodiments:
The above embodiment is an example for carrying out the present invention. When the vehicle is traveling, a past evaluation having an evaluation level worse than a predetermined evaluation level is displayed on the map, and the vehicle is not traveling. As long as past evaluations of all evaluation levels are displayed on the map, various other embodiments can be adopted. For example, the current evaluation and the past evaluation may be acquired from an apparatus not mounted on the vehicle, for example, an information management center. Of course, the navigation terminal 10 may be fixedly mounted on the vehicle, or the portable navigation terminal 10 may be brought into the vehicle and used.

  Furthermore, although the above-mentioned vehicle is a vehicle driven by an internal combustion engine, the application target vehicle is not limited to such a vehicle, and the present evaluation and past evaluation are displayed on a map in a hybrid vehicle or an electric vehicle. It may be.

  Further, the evaluation of the fuel consumption may be evaluated based on a condition for a combination of a plurality of elements, or may be evaluated based on a condition for a single element (for example, a fuel consumption value). Further, in a hybrid vehicle driven using liquid fuel and a battery, it may be determined that fuel efficiency is good when the vehicle travels only with a power source having a low unit price for traveling the same distance. For example, when driving a vehicle with a battery can travel the same distance cheaper than with liquid fuel, it is possible to adopt a configuration in which it is judged that the fuel consumption of the state driven using the battery without using liquid fuel is good is there. Of course, in addition to the evaluation of the fuel consumption, an evaluation of the fuel consumption during hybrid driving may be performed. Further, the fuel consumption may be evaluated in two stages as in the above-described embodiment, or may be evaluated in three or more stages.

  Furthermore, the evaluation of the fuel consumption may be information that serves as a guideline for changing the fuel consumption, may be information indicating the value of the fuel consumption (for example, information indicating the average value in the unit section), Information indicating the result of comparing the fuel efficiency with the current fuel efficiency (for example, information indicating a relative relationship with the reference fuel efficiency) may be used.

  In addition to the configuration in which the departure point and the destination are determined when the driver explicitly indicates the destination as described above, various configurations can be adopted. For example, you may employ | adopt the structure which uses the point determined that the vehicle departed based on the operation state of the vehicle, or the point determined to arrive as a starting point or a destination. Further, the current destination may be estimated based on, for example, the current travel route, past travel history, and the like.

  Furthermore, in the above-described embodiment, when the vehicle travels in the past from the same starting point to the same destination as the starting point and destination in the current traveling, the traveling section is the display target of the past evaluation. A display target section for past evaluation may be determined according to a rule. That is, of the past travel sections displayed on the map, the section to be compared with the current evaluation is set as the display target section for the past evaluation, and the evaluation of fuel consumption for each unit section for the display target section is performed in the past evaluation. And it is sufficient. The past evaluation display target section may be all or a part of sections in which past evaluation information exists. For example, it is good also as a structure which displays the past evaluation in all or some sections of the unit section with the information which can specify past evaluation around the present position. Of course, the displayed evaluation level of the past evaluation is switched depending on the traveling state of the vehicle. In this configuration, if the total fuel consumption is high during the current trip to the current position and the driver wants to suppress the fuel consumption in future trips, he / she will drive in the unit section where the past evaluation is displayed during the run. If you are aware of improved operation, you can effectively improve fuel efficiency.

  Further, the unit section may be a section for deriving the conclusion of the evaluation regarding fuel consumption, and a section determined by a predetermined rule may be used as the unit section in addition to the structure having the section of a constant distance as the unit section. For example, it is possible to adopt a configuration in which one link whose end point is the closest node indicated by the map information is one unit section. Furthermore, the unit section that is the target for displaying the current evaluation and the unit section that is the target for displaying the past evaluation may be the same or different. That is, it is only necessary that the unit section is determined by a common rule, and the unit section to be displayed may be appropriately selected.

  Furthermore, for the current evaluation, evaluations with an evaluation level worse than a predetermined evaluation level may be displayed, evaluations for all evaluation levels may be displayed, and display targets may be displayed depending on whether the vehicle is running or not. You may switch the evaluation level.

  Further, the evaluation level of the display target may be specified in consideration of factors other than the running state of the vehicle. For example, when the vehicle is traveling, a unit section in which a past evaluation having an evaluation level worse than a predetermined evaluation level continues for a predetermined number of sections or more is specified, and the past evaluation for the specified unit section is displayed on a map. It is good also as a structure. That is, during traveling, the past evaluation is displayed only when the past evaluation having an evaluation level worse than the predetermined evaluation level continues for a predetermined number of sections or more. For example, in the case where the past travel is “bad” evaluation in the unit section indicated by the broken line icon Epb in FIG. 4B, the past evaluation is displayed only when the “bad” evaluation continues for three or more sections. If so, only the past evaluation of the unit section shown in the section Zb among the past evaluations shown in FIG. 4B is displayed during traveling.

  As described above, when past evaluations of “bad” evaluation are continued in the section Zb, it is highly possible that the fuel efficiency is deteriorated due to a common factor in the section Zb, and the driver improves the fuel efficiency. There is a high possibility that fuel efficiency will be greatly improved. Therefore, in FIG. 4B, only the past evaluation of the section Zb is set as a display target during traveling, for example, past evaluations for unit sections in which past evaluations of evaluation levels worse than a predetermined evaluation level continue for a predetermined number of sections or more are mapped. If it is set as the structure displayed on the top, the highly important information which contributes to the improvement of a fuel consumption can be provided to a driver | operator.

  Furthermore, when the vehicle is running and the scale of the map is a scale for displaying a map of an area having a predetermined area or more on the display unit, a past evaluation having an evaluation level worse than the predetermined evaluation level is displayed on the map. It is good also as a structure displayed on. That is, when the scale of the map is variable, the amount of information to be displayed tends to increase as the map display area becomes wider due to the change in the scale. FIG. 4C shows a map whose scale has been changed so that the displayed area is narrower than that in FIG. 4B. When FIG. 4B is compared with FIG. 4C, FIG. 4B displays a larger area. Along with this, there are a large number of icons Etb, Etg, Epb, and Epg indicating past evaluation and current evaluation.

  Therefore, when the past scale is displayed for all the evaluation levels, the scale of the map scale may cause trouble in recognition of the evaluation level when the scale of the map is a scale for displaying a map of an area having a predetermined area or more on the display unit. Is determined in advance. When the map is scaled and the scale of the map is the determined scale, if a past evaluation having an evaluation level worse than a predetermined evaluation level is displayed on the map, a large number of past evaluations are displayed and evaluated. It is possible to prevent the recognition of the level from being hindered. For example, when the scale shown in FIG. 4C is configured to display the past evaluation of “good” evaluation even while traveling, and when the scale is switched to the scale shown in FIG. The map shown in FIG. 4A is displayed, and the past evaluation of “good” evaluation is not displayed during traveling. As a result, in the map shown in FIG. 4A, it is possible to prevent a large number of past evaluations from being displayed and hinder recognition of the evaluation level.
