Description

  The present invention relates to a navigation system, a navigation method, and a navigation program.

  Conventionally, a navigation system that guides a travel route of a vehicle has been used. In recent years, demand for fuel-saving driving has increased from the viewpoint of fuel cost saving and environmental conservation, and a navigation system that provides guidance for the purpose of reducing fuel consumption during vehicle driving has also been proposed.

  For example, in order to allow the user to specifically understand the section to be driven with caution to improve fuel efficiency, it is possible to identify a link in which the vehicle has consumed fuel that exceeds the reference fuel consumption in the traveling locus of the vehicle. Thus, a navigation device that highlights the link on a map has been proposed. In this navigation device, the reference fuel consumption is calculated based on the fuel consumption in the past travel, and the link where the vehicle consumed the fuel exceeding the reference fuel consumption in the current travel is highlighted on the map (for example, , See Patent Document 1).

JP 2011-33447 A

  In the conventional apparatus as described above, the comparison result between the fuel consumption in the past driving and the fuel consumption in the current driving is displayed on the map. How suitable is the driving operation by the driver for reducing the fuel consumption? It is also conceivable that the user himself / herself can compare the evaluation results by displaying the evaluation results on the screen for each of the past travel and the current travel. As described above, when the evaluation result of the driving operation in the past traveling and the evaluation result of the driving operation in the current traveling are displayed on the screen so that they can be compared, the same traveling route as the current traveling route is displayed in the past. It is necessary to determine whether or not the vehicle has traveled. For example, when the destination on the current travel route of the vehicle is the same as the destination on the past travel route, and the departure point on the current travel route is within a predetermined range including the departure point on the past travel route In addition, the current travel route and the past travel route may be the same. In this case, there is a case where the departure place is different within a predetermined range between the current travel route and the past travel route.

(Constitution)
First, the configuration of the navigation system will be described. FIG. 1 is a block diagram illustrating a navigation system according to this embodiment. The navigation system 1 is mounted on a vehicle, for example, and is connected to an ECU 2 (Electronic Control Unit), a current position detection processing unit 3, an operation unit 4, a display 5, and a speaker 6 as shown in FIG.

The ECU 2 monitors the state of each part of the vehicle via various sensors, and controls each part of the vehicle such as a power system such as an engine and a motor generator of the vehicle, a transmission, a drive system, and a braking system (all not shown). For example, the transmission is controlled by acquiring a vehicle speed pulse signal proportional to the rotational speed of the axle from the vehicle speed sensor, or the fuel injection device (not shown) is controlled based on the oxygen concentration in the exhaust gas acquired from the O 2 sensor. . Various information such as a vehicle speed pulse signal and a fuel injection amount is input to the navigation system 1 from the ECU 2.

Specifically, the current position detection processing unit 3 includes at least one of a GPS, a geomagnetic sensor, a distance sensor, and a gyro sensor (all of which are not shown), and determines the current vehicle position (coordinates), direction, and the like. Detection is performed by a known method.

(Configuration-operation unit)
The operation unit 4 is an operation unit that receives an operation input by a user. The specific configuration of the operation unit 4 is arbitrary. For example, a remote operation unit such as a touch panel, a push button, and a remote controller provided on the front surface of the display 5 or a voice recognition unit such as a microphone for receiving voice input is used. Thus, the operation unit 4 can be configured.

(Configuration-Display)

(Configuration-Navigation system)
The navigation system 1 includes a control unit 10 and a data recording unit 20.

(Configuration-Navigation system-Control unit)
The control unit 10 is a control unit that controls the navigation system 1, and specifically, a CPU, various programs that are interpreted and executed on the CPU (a basic control program such as an OS, and a specific function that is activated on the OS And an internal memory such as a RAM for storing the program and various data. In particular, the navigation program according to the present embodiment is substantially installed in the navigation system 1 via an arbitrary recording medium or network, thereby substantially configuring each unit of the control unit 10.

  The control unit 10 includes an evaluation information acquisition unit 11, an evaluation unit 12, a travel route determination unit 13, and an evaluation standard setting unit 14 in terms of functional concept. The evaluation information acquisition unit 11 is an evaluation information acquisition unit that acquires evaluation information that serves as an index for evaluating a driving operation performed by a vehicle driver. For example, when an eco lamp indicating whether or not the driving operation by the driver is suitable for improving fuel efficiency is displayed in a meter panel (not shown) of the vehicle, the evaluation information acquisition unit 11 receives the eco lamp from the ECU 2 or the like. The information for specifying the lighting / light-off state is acquired as evaluation information and recorded in storage means (not shown) such as a RAM. The evaluation unit 12 is an evaluation unit that evaluates the driving operation by the driver. For example, the evaluation unit 12 is based on the evaluation information acquired by the evaluation information acquisition unit 11 for each evaluation section for evaluating the driving operation by the driver, and the total distance traveled by the vehicle in the state where the eco lamp is lit in each evaluation section. Is calculated. Then, a value obtained by dividing the calculated distance by the distance of each evaluation section (that is, the ratio of the travel distance of the vehicle when the driving operation by the driver is suitable for improving fuel efficiency in the evaluation section) is a predetermined evaluation criterion. In the above case, it is evaluated that the driving operation by the driver in the evaluation section is suitable for improving the fuel efficiency, and when the driving operation is less than a predetermined evaluation standard, the driving operation by the driver in the evaluation section is not suitable for improving the fuel efficiency. And evaluate. The travel route determination unit 13 is a travel route determination unit that determines whether the current travel route of the vehicle and the past travel route are the same. The evaluation criterion setting unit 14 is an evaluation criterion setting unit that sets an evaluation criterion serving as a criterion when the evaluation unit 12 evaluates the driving operation performed by the driver of the vehicle. Details of processing executed by each unit of these control units 10 will be described later.

(Configuration-Navigation system-Data recording part)
The data recording unit 20 is a recording unit that records programs and various data necessary for the operation of the navigation system 1, and is configured using a magnetic recording medium such as a hard disk (not shown) as an external storage device. ing. However, any other recording medium including a semiconductor storage medium such as a flash memory or an optical recording medium such as a DVD or a Blu-ray disk can be used instead of or together with the hard disk.

  The data recording unit 20 includes a map information database 21 (hereinafter, the database is abbreviated as DB) and an evaluation criterion table 22.

  The map information DB 21 is map information storage means for storing map information. “Map information” includes, for example, link data (link number, connection node number, road coordinates, road type, number of lanes, travel restrictions, etc.), node data (node number, coordinates), feature data (signals, road signs, guardrails) , Buildings, etc.), facility data (position of each facility, type of each facility, etc.), topographic data, map display data for displaying a map on the display 5, and the like.

  The evaluation criterion table 22 correlates the departure candidate information that uniquely identifies each departure candidate with the evaluation criterion information that specifies the evaluation criterion corresponding to each section from each departure candidate to the first evaluation point. And storing evaluation criteria information. The specific contents of each information stored in the evaluation criterion table 22, the timing at which each information is stored in the evaluation criterion table 22, and the like will be described later.

(Processing-Navigation processing)
Next, navigation processing executed by the navigation system 1 configured as described above will be described. FIG. 2 is a flowchart of the navigation process (steps are abbreviated as “S” in the description of each process below). This navigation process is started, for example, when the navigation system 1 is powered on.

  When the navigation process is started, the travel route determination unit 13 waits until the travel destination of the vehicle is set by an operation input via the operation unit 4 (SA1, No). Here, “destination setting” means that a final destination is set by an operation input via the operation unit 4, and a plurality of already set destinations are input via the operation unit 4. Including the case where different destinations are set as final destinations, or the case where final destinations that have already been set are deleted and other destinations are set as final destinations.

  When the destination is set (SA1, Yes), the travel route determination unit 13 travels from the current departure point (for example, the current position detected by the current position detection processing unit 3) to the destination set in SA1. It is determined whether the vehicle has traveled in the past on the same travel route as the route (SA2). Specifically, the travel route determination unit 13 has the same destination in the current travel route and the destination in the past travel route, and the departure point in the current travel route is the departure in the past travel route. When the vehicle is within a predetermined range including the ground (for example, within a circle having a radius of 300 m centering on the departure point in the past travel route), the current travel route of the vehicle is determined to be the same as the past travel route. To do.

  As a result, when the vehicle has not traveled in the past on the same travel route from the current departure point to the destination set in SA1 (SA2, No), that is, the current departure point is set in SA1. When the vehicle travels for the first time on the travel route to the destination, the evaluation criterion setting unit 14 executes an evaluation criterion table creation process (SA3).

(Processing-Evaluation criteria table creation processing)
Here, the evaluation criteria table creation process will be described. FIG. 3 is a flowchart of the evaluation criteria table creation process. As shown in FIG. 3, when the evaluation criterion table creation process is started, the evaluation criterion setting unit 14 sets an initial evaluation point (SB1). Here, the “initial evaluation point” is an end point of a section to be evaluated first for a driving operation by the driver of the vehicle after the vehicle departs from the departure place on the travel route. For example, the evaluation criterion setting unit 14 is a point where the outer periphery of a predetermined range including the departure point on the current travel route (for example, a circle with a radius of 300 m centering on the departure point on the current travel route) and the travel route of the vehicle intersect. Is set as the first evaluation point. Or you may make it set the point which drive | worked the predetermined distance (for example, 300m) from the departure place along a driving | running | working path | route as an initial evaluation point.

  Next, the evaluation criterion setting unit 14 performs other departures of the travel route within a predetermined range including the departure point on the current travel route (for example, within a circle having a radius of 300 m centering on the departure point on the current travel route). A departure point candidate that can be a ground is specified (SB2). For example, the evaluation criterion setting unit 14 specifies a predetermined facility (for example, a parking lot or a commercial facility) existing within a predetermined range including the departure place on the current travel route as a departure place candidate. In this case, only the facility whose attribute is related to the departure place on the current travel route (for example, the facility related to the company P when the departure place on the current travel route is a parking lot of the company P) is specified as the departure place candidate. You may make it do. In addition, each node existing within a predetermined range including the departure place on the current travel route may be specified as a departure place candidate.

  Subsequently, the evaluation criterion setting unit 14 determines each route from each departure point candidate specified in SB2 to the first evaluation point set in SB1 and each route from the departure point to the first evaluation point in the current travel route. A characteristic value indicating a characteristic that affects the evaluation result by the evaluation unit 12 is specified (SB3). Here, the “characteristic value indicating the characteristic that affects the evaluation result by the evaluation unit 12” means that when the evaluation unit 12 evaluates whether or not the driving operation by the driver is suitable for improving the fuel consumption, It is a value indicating the characteristics of the path that affects the evaluation result. For example, as the travel distance of the route becomes longer, the proportion of the section in which the vehicle can travel at a constant speed increases (that is, the proportion of the section in which the accelerator opening increases to accelerate the vehicle decreases). Therefore, it becomes easy to evaluate that the driving operation by the driver is suitable for improving the fuel consumption. Therefore, the travel distance of each route can be used as a characteristic value indicating a characteristic that affects the evaluation result by the evaluation unit 12. In addition, as the route cost in the route (for example, a value calculated according to the number of signalized intersections in the route, the climbing slope in the route, etc.) is lower (for example, the number of signalized intersections is smaller or the number of climbing roads is smaller), The proportion of the section in which the vehicle can travel at a constant speed increases (that is, the ratio of the section in which the accelerator opening is increased in order to accelerate the vehicle decreases). It becomes easy to be evaluated as being suitable for improving fuel consumption. Therefore, the route cost of each route may be used as a characteristic value indicating a characteristic that affects the evaluation result by the evaluation unit 12.

  FIG. 4 is a plan view conceptually showing the starting point in the driving route and the characteristic values in each route from each starting point candidate to the first evaluation point. FIG. 4A uses the driving distance of the route as the characteristic value. FIG. 4B is a diagram showing a case where the route cost of the route is used as the characteristic value. In the example of FIG. 4, departure point candidates B, C, D, and E exist in a circle with a radius of 300 m including the departure point A in the current travel route. Further, a point F where the outer periphery of a circle with a radius of 300 m centering on the departure point A and the travel route of the vehicle intersect is set as the first evaluation point. In FIG. 4A, the travel distance as a characteristic value in the route from the departure point A to the first evaluation point F is 300 m, the travel distance as the characteristic value in the route from the departure point candidate B to the first evaluation point F is 400 m, The travel distance as a characteristic value in the route from the departure point candidate C to the first evaluation point F is 500 m, the travel distance as a characteristic value in the route from the departure point candidate D to the first evaluation point F is 200 m, and the first departure point from the departure point candidate E The travel distance as a characteristic value on the route to the evaluation point F is specified as 100 m. In FIG. 4B, the route cost as the characteristic value in the route from the departure point A to the first evaluation point F is 2, and the route cost as the characteristic value in the route from the departure point candidate B to the first evaluation point F is 3. The route cost as the characteristic value in the route from the departure point candidate C to the initial evaluation point F is 5, the route cost as the characteristic value in the route from the departure point candidate D to the initial evaluation point F is 4, and from the departure point candidate E The route cost as the characteristic value in the route to the first evaluation point F is specified as 1.

  Returning to FIG. 3, after the process of SB3, the evaluation criterion setting unit 14 determines the characteristic value of each route from each departure point candidate specified in SB3 to the first evaluation point, and the first evaluation point from the departure point in the current travel route. An average value with the characteristic value of the route up to is calculated (SB4). In the example of FIG. 4A, the average value of characteristic values (travel distance) of each route = {(travel distance 300 m from A to F) + (travel distance 400 m from B to F) + (from C to F) Mileage 500m) + (travel distance 200m from D to F) + (travel distance 100m from E to F)} / 5 = 300m. In the example of FIG. 4B, the average value of the characteristic values (route costs) of each route = {(route cost 2 from A to F) + (route cost 3 from B to F) + (from C Route cost 5 from F) + (Route cost 4 from D to F) + (Route cost 1 from E to F)} / 5 = 3.

  Returning to FIG. 3, after the processing of SB4, the evaluation criterion setting unit 14 determines the evaluation criterion corresponding to each section from each departure point candidate to the first evaluation point, and from the departure point to the first evaluation point on the current travel route. An evaluation criterion corresponding to the section is set (SB5), and the identification information for uniquely identifying each section and the evaluation criterion information for specifying the evaluation criterion set corresponding to each section are associated with each other, and the evaluation criterion Store in the table 22 (SB6). For example, information for specifying a combination of a departure point and a destination on the current travel route is added to the evaluation reference table 22 as information for identifying the travel route. Furthermore, the average value of the characteristic value of each route from the starting point to the first evaluation point in the current driving route and the characteristic value of the route from the starting point to the first evaluation point in the current driving route Information to be identified is also added to the evaluation criterion table 22.

  In SB5, the evaluation criterion setting unit 14 calculates the average value of the characteristic values of each route from the departure point to the first evaluation point in the current travel route and each departure point candidate calculated in SB4 and the current travel point. Based on the difference between the characteristic value of each route from the starting point to the first evaluation point on the route, the evaluation criteria corresponding to each candidate from the starting point and each section from the starting point to the first evaluation point on the current driving route are set. . Here, the “evaluation standard” is a standard when the evaluation unit 12 evaluates for each evaluation section whether or not the driving operation by the driver is suitable for improving the fuel consumption. For example, the evaluation unit 12 determines whether or not the ratio of the mileage of the vehicle when the driving operation by the driver in the evaluation section is suitable for improving the fuel consumption (that is, the state where the eco lamp is lit) is equal to or higher than a predetermined evaluation criterion. It is evaluated whether or not the driving operation in the evaluation section is suitable for improving fuel consumption.

  FIG. 5 is a table illustrating information stored in the evaluation criterion table 22, FIG. 5 (a) is a table showing a case where travel distance is used as a characteristic value, and FIG. 5 (b) is a route cost as characteristic value. It is a table | surface which shows the case where is used. As shown in FIG. 5, the evaluation criterion table 22 stores information corresponding to the items “departure location”, “characteristic value”, “difference”, and “evaluation criterion” in association with each other. The information stored corresponding to the item “Departure point” is identification information that uniquely identifies each section from each departure point candidate to the first evaluation point, and a section from the departure point to the first evaluation point in the current travel route. For example, each departure point candidate or the name of the departure point in the current travel route is stored (“A” in FIG. 5). The information stored corresponding to the item “characteristic value” is information for specifying the characteristic value (“200” in FIG. 5). The information stored corresponding to the item “difference” is for specifying a difference obtained by subtracting the average value of the characteristic values of each route from the characteristic value of each route (hereinafter referred to as “characteristic value difference” if necessary). (In FIG. 5, “−100” etc.). The information stored in association with the item “evaluation criteria” is evaluation criteria information for specifying the evaluation criteria set corresponding to each section (“85%” in FIG. 5).

  For example, when the travel distance is used as the characteristic value, the evaluation criterion setting unit 14 increases the evaluation criterion as the difference between the characteristic values increases (that is, as the travel distance from the departure point or departure point candidate to the first evaluation point increases). (That is, it is difficult to evaluate that the driving operation by the driver is suitable for improving fuel efficiency). For example, when the difference between the characteristic values is −50 m or more and less than 50 m, the evaluation criterion setting unit 14 sets a predetermined standard evaluation criterion (for example, 90%) as the evaluation criterion. When the difference between the characteristic values is 50 m or more and less than 150 m, a value (for example, 95%) obtained by increasing a predetermined standard evaluation criterion by 5% is set as the evaluation criterion. When the difference between the characteristic values is 150 m or more, a value (for example, 100%) obtained by increasing a predetermined standard evaluation criterion by 10% is set as the evaluation criterion. When the difference between the characteristic values is −150 m or more and less than −50 m, a value (for example, 85%) obtained by reducing the predetermined standard evaluation standard by 5% is set as the evaluation standard. When the difference between the characteristic values is less than −150 m, a value (for example, 80%) obtained by reducing the predetermined standard evaluation standard by 10% is set as the evaluation standard.

  In the example of FIG. 4A, the average value of characteristic values (travel distance) of each route is calculated as 300 m in SB4. On the other hand, since the travel distance as the characteristic value in the route from the departure point A to the first evaluation point F is 300 m, the difference between the characteristic values is calculated as 0 m. Therefore, as shown in FIG. 5A, the evaluation criterion corresponding to the section from the departure point A to the first evaluation point F on the current travel route is set to 90%, which is a predetermined standard evaluation criterion. Further, since the travel distance as the characteristic value in the route from the departure point candidate B to the first evaluation point F is 400 m, the difference between the characteristic values is calculated as +100 m. Accordingly, as shown in FIG. 5A, the evaluation criterion corresponding to the section from the departure point candidate B to the first evaluation point F is set to 95%. Further, since the travel distance as the characteristic value in the route from the departure point candidate C to the first evaluation point F is 500 m, the difference between the characteristic values is calculated as +200 m. Therefore, as shown in FIG. 5A, the evaluation criterion corresponding to the section from the departure point candidate C to the first evaluation point F is set to 100%. Further, since the travel distance as the characteristic value in the route from the departure point candidate D to the first evaluation point F is 200 m, the difference between the characteristic values is calculated as −100 m. Therefore, as shown in FIG. 5A, the evaluation criterion corresponding to the section from the departure point candidate D to the initial evaluation point F is set to 85%. Further, since the travel distance as the characteristic value in the route from the departure point candidate E to the first evaluation point F is 100 m, the difference between the characteristic values is calculated as -200 m. Therefore, as shown in FIG. 5A, the evaluation criterion corresponding to the section from the departure point candidate E to the first evaluation point F is set to 80%.

  When the route cost is used as the characteristic value, the evaluation criterion setting unit 14 increases the evaluation criterion as the difference between the characteristic values decreases (that is, as the route cost from the departure point or departure point candidate to the first evaluation point decreases). (That is, it is difficult to evaluate that the driving operation by the driver is suitable for improving fuel efficiency). For example, the evaluation standard setting unit 14 sets a predetermined standard evaluation standard (for example, 90%) as the evaluation standard when the difference between the characteristic values is −0.5 or more and less than 0.5. When the difference between the characteristic values is 0.5 or more and less than 1.5, a value (for example, 85%) obtained by reducing the predetermined standard evaluation standard by 5% is set as the evaluation standard. When the difference between the characteristic values is 1.5 or more, a value (for example, 80%) obtained by reducing a predetermined standard evaluation criterion by 10% is set as the evaluation criterion. When the difference between the characteristic values is −1.5 or more and less than −0.5, a value (for example, 95%) obtained by increasing a predetermined standard evaluation criterion by 5% is set as the evaluation criterion. When the difference between the characteristic values is less than −1.5, a value (for example, 100%) obtained by increasing the predetermined standard evaluation standard by 10% is set as the evaluation standard.

  In the example of FIG. 4B, the average value of characteristic values (travel distance) of each route is calculated as 3 in SB4. On the other hand, since the route cost as the characteristic value in the route from the departure point A to the first evaluation point F is 2, the difference between the characteristic values is calculated as -1. Therefore, as shown in FIG. 5B, the evaluation criterion corresponding to the section from the departure point A to the first evaluation point F on the current travel route is set to 95%. Further, since the route cost as the characteristic value in the route from the departure point candidate B to the first evaluation point F is 3, the difference between the characteristic values is calculated as 0. Therefore, as shown in FIG. 5B, the evaluation criterion corresponding to the section from the departure point candidate B to the initial evaluation point F is set to 90%, which is a predetermined standard evaluation criterion. Further, since the route cost as the characteristic value in the route from the departure point candidate C to the first evaluation point F is 5, the difference between the characteristic values is calculated as +2. Accordingly, as shown in FIG. 5B, the evaluation criterion corresponding to the section from the departure point candidate C to the initial evaluation point F is set to 80%. Further, since the route cost as the characteristic value in the route from the departure point candidate D to the first evaluation point F is 4, the difference between the characteristic values is calculated as +1. Therefore, as shown in FIG. 5B, the evaluation criterion corresponding to the section from the departure point candidate D to the initial evaluation point F is set to 85%. Further, since the route cost as the characteristic value in the route from the departure point candidate E to the first evaluation point F is 1, the difference between the characteristic values is calculated as −2. Accordingly, as shown in FIG. 5B, the evaluation criterion corresponding to the section from the departure point candidate E to the initial evaluation point F is set to 100%.

  Returning to FIG. 3, after the process of SB6, the control unit 10 ends the evaluation reference table creation process and returns to the main routine.

  Returning to FIG. 2, in the process of SA2, when the vehicle has traveled in the past on the same travel route from the current departure point to the destination set in SA1 (SA2, Yes), the evaluation criterion setting unit 14 Performs the evaluation standard setting process (SA4).

(Processing-Evaluation standard setting processing)
Here, the evaluation standard setting process will be described. FIG. 6 is a flowchart of the evaluation criterion setting process. As shown in FIG. 6, when the evaluation standard setting process is started, the evaluation standard setting unit 14 determines that the initial evaluation point on the current travel route is the same as the current travel route in SA2 of FIG. It is set at the same position as the initial evaluation point on the travel route, and the characteristic value for the route from the departure point on the current travel route to the initial evaluation point is specified (SC1). For example, the evaluation standard setting unit 14 is information added to the evaluation standard table 22 corresponding to the past travel route determined to be the same as the travel route from the current departure place to the destination set in SA1 in FIG. Based on the above, the first evaluation point on the past driving route is identified, the first evaluation point is set as the first evaluation point on the current driving route, and the route from the departure point on the current driving route to the first evaluation point is determined. Identify characteristic values.

  Next, the evaluation criterion setting unit 14 sets an evaluation criterion corresponding to the section from the departure point to the first evaluation point on the current travel route (SC2). Specifically, the evaluation criterion setting unit 14 averages the characteristic values specified for each route from each departure point candidate to the first evaluation point on the travel route determined to be the same as the current travel route in SA2 of FIG. Based on the difference between the value and the characteristic value of the route from the departure point to the first evaluation point on the current travel route, an evaluation criterion corresponding to the section from the departure point to the first evaluation point on the current travel route is set.

  For example, the evaluation standard setting unit 14 refers to the evaluation standard table 22 corresponding to the travel route determined to be the same as the travel route from the current departure point to the destination set in SA1 in FIG. An evaluation criterion corresponding to the characteristic value for the route from the departure point to the first evaluation point on the current travel route is identified, and the evaluation criterion corresponding to the section from the departure point to the first evaluation point on the current travel route Set as.

  For example, the evaluation reference table 22 illustrated in FIG. 5A is used as the evaluation reference table 22 corresponding to the travel route determined to be the same as the travel route from the current departure point to the destination set in SA1 in FIG. In the case of reference, when the travel distance as the characteristic value in the route from the current departure point to the first evaluation point is 400 m (that is, when the difference from the average characteristic value of 300 m is +100 m), FIG. According to a), the evaluation criterion is set to 95%.

  Further, the evaluation criterion table 22 illustrated in FIG. 5B is used as the evaluation criterion table 22 corresponding to the traveling route determined to be the same as the traveling route from the current departure point to the destination set in SA1 in FIG. In the case of reference, when the route cost as the characteristic value in the route from the current departure point to the first evaluation point is 5 (that is, when the difference from the average value 3 of the characteristic value is +2), FIG. According to b), the evaluation criterion is set to 80%.

  Further, the evaluation criterion setting unit 14 refers to the evaluation criterion table 22 corresponding to the traveling route determined to be the same as the traveling route from the current departure point to the destination set in SA1 in FIG. The evaluation criterion corresponding to the departure place on the current travel route may be specified.

  For example, the evaluation reference table 22 illustrated in FIG. 5A is used as the evaluation reference table 22 corresponding to the travel route determined to be the same as the travel route from the current departure point to the destination set in SA1 in FIG. In the case of reference, if the current departure point is B, the evaluation criterion is set to 95% according to FIG.

  Further, the evaluation criterion table 22 illustrated in FIG. 5B is used as the evaluation criterion table 22 corresponding to the traveling route determined to be the same as the traveling route from the current departure point to the destination set in SA1 in FIG. In the case of reference, when the current departure point is C, the evaluation criterion is set to 80% according to FIG. 5B.

  It should be noted that an evaluation criterion corresponding to the same characteristic value as the characteristic value for the route from the starting point to the first evaluation point in the current travel route specified in SC1 is not stored in the evaluation criterion table 22, or specified in SC1. If the evaluation criteria corresponding to the same departure location as the departure location on the current travel route is not stored in the evaluation criteria table 22, the characteristic value for the route from the departure location to the first evaluation location on the current travel route An evaluation criterion corresponding to the characteristic value closest to may be acquired from the evaluation criterion table 22.

  Returning to FIG. 6, after the process of SC2, the control unit 10 ends the evaluation criterion setting process and returns to the main routine.

  Returning to FIG. 2, after the processing of SA3 or SA4, the control unit 10 starts route guidance from the current departure point to the destination set in SA1 (SA5). Detailed description of the route search from the departure point to the destination and the specific content of the route guidance based on the search result is omitted because a known route search method and route guidance method can be used. . After the route guidance is started in SA5, the evaluation information acquisition unit 11 sequentially acquires information for specifying the lighting / extinguishing state of the eco lamp as evaluation information from the ECU 2 or the like, and records it in a storage unit such as a RAM.

  Subsequently, the evaluation unit 12 waits until the vehicle reaches the first evaluation point on the current travel route based on the current position detected by the current position detection processing unit 3 (SA6, No).

  When the vehicle reaches the first evaluation point on the current travel route (SA6, Yes), the evaluation unit 12 receives the evaluation information acquired in the section from the departure place to the first evaluation point by the evaluation information acquisition unit 11, and FIG. Based on the evaluation criteria corresponding to the section from the starting point to the first evaluation point on the current driving route set in SC2 in FIG. 6 or SC2 in FIG. 6, the driver in the section from the starting point on the current driving route to the first evaluation point The driving operation by is evaluated (SA7). Specifically, the evaluation unit 12 is based on the evaluation information acquired by the evaluation information acquisition unit 11 for the section from the departure point to the first evaluation point on the current travel route, and the vehicle is in a state where the eco lamp is lit in the section. Calculate the total distance traveled. Then, the value obtained by dividing the calculated distance by the distance of the section (that is, the ratio of the travel distance of the vehicle when the driving operation by the driver is suitable for improving the fuel consumption in the section) is SB5 in FIG. Alternatively, if the evaluation standard corresponding to the section from the starting point to the first evaluation point in the current travel route set in SC2 in FIG. 6 is equal to or higher than the evaluation standard, it is evaluated that the driving operation by the driver in the section is suitable for improving the fuel consumption. If it is less than the evaluation criterion, it is evaluated that the driving operation by the driver in the section is not suitable for improving the fuel consumption. For example, in the section from the starting point on the current travel route to the first evaluation point, the proportion of the travel distance of the vehicle when the driving operation by the driver is suitable for improving fuel efficiency is 92%, and SB5 in FIG. When the evaluation standard corresponding to the section from the starting point to the first evaluation point on the current travel route set in SC2 of No. 6 is 95%, the evaluation unit 12 determines that the driving operation by the driver in the section is suitable for improving fuel efficiency. Evaluate not. In addition, the evaluation unit 12 displays the evaluation result by the evaluation unit 12 on the map displayed on the display 5 at a position corresponding to a section from the departure point to the first evaluation point on the current travel route (for example, the first evaluation point). (Overlapping position).

  Subsequently, the evaluation unit 12 waits until the vehicle travels a predetermined distance (for example, 100 m) after last evaluating the driving operation by the driver based on the current position detected by the current position detection processing unit 3 (SA8). , No).

  When the vehicle has traveled a predetermined distance after the last evaluation of the driving operation by the driver (SA8, Yes), the evaluation unit 12 evaluates the evaluation section at a predetermined distance from the point where the driving operation by the driver was last evaluated. Based on the evaluation information acquired by the information acquisition unit 11 and a standard evaluation criterion (for example, 90%), the driving operation by the driver in the evaluation section is evaluated (SA9). Specifically, the evaluation unit 12 turns on the eco lamp in the evaluation section based on the evaluation information acquired by the evaluation information acquisition unit 11 for the evaluation section of a predetermined distance from the point where the driving operation by the driver was last evaluated. The total distance traveled by the vehicle in the state is calculated. Then, the value obtained by dividing the calculated distance by the distance of the evaluation section (that is, the ratio of the travel distance of the vehicle when the driving operation by the driver is suitable for improving the fuel consumption in the evaluation section) is a standard evaluation. If the vehicle is above the standard, it is evaluated that the driving operation by the driver in the evaluation section is suitable for improving the fuel efficiency, and if it is less than the standard evaluation standard, the driving operation by the driver in the evaluation section is not suitable for improving the fuel efficiency. And evaluate. For example, when the driving mileage of the vehicle when the driving operation by the driver is suitable for improving the fuel efficiency in the evaluation section is 92% and the standard evaluation criterion is 90%, the evaluation unit 12 It is evaluated that the driving operation by the driver in is suitable for improving fuel efficiency. Further, the evaluation unit 12 superimposes and displays the evaluation result by the evaluation unit 12 at a position (for example, the position of the end point of the evaluation section) corresponding to the evaluation section on the map displayed on the display 5.

  Next, the evaluation unit 12 determines whether or not the vehicle has arrived at the destination set in SA1 based on the current position detected by the current position detection processing unit 3 (SA10).

  As a result, when the vehicle has not arrived at the destination (SA10, No), the process returns to SA8. Thereafter, the processing from SA8 to SA10 is repeated until the vehicle arrives at the destination.

  On the other hand, when the vehicle arrives at the destination set in SA1 (SA10, Yes), the control unit 10 ends the navigation process.

(effect)
As described above, according to the present embodiment, when the travel route determination unit 13 determines that the current travel route of the vehicle and the past travel route are the same, the evaluation criterion setting unit 14 performs the first time on the current travel route. The evaluation point is set at the same position as the initial evaluation point on the past driving route, the route from the starting point to the first evaluation point on the past driving route, and the route from the starting point to the first evaluation point on the current driving route For each of these, a characteristic value indicating a characteristic that affects the evaluation result by the evaluation unit 12 is specified, and an evaluation corresponding to a section from the starting point to the first evaluation point in the current travel route is performed based on the specified characteristic value. Since the standard is set, considering the characteristic value that indicates the characteristic that affects the evaluation result, the current driving route and the past driving route are common from the starting point. It is possible to evaluate the driving operation in the interval of up to initial evaluation point, and the results past evaluation result and the current evaluation can be fair comparison.

  In addition, the evaluation criterion setting unit 14 sets a point at which the outer periphery of a predetermined range including the departure point on the past travel route of the vehicle and the travel route of the vehicle intersect as the initial evaluation point, so the current travel route and the past It is possible to set an appropriate point as a common initial evaluation point with the travel route.

  In addition, when the travel route determination unit 13 determines that the current travel route of the vehicle and the past travel route are the same, the evaluation criterion setting unit 14 travels within the predetermined range including the departure place on the past travel route. Characteristic values are specified for each route from each starting point candidate that can be the starting point of the route to the first evaluation point, and each route from the starting point to the first evaluation point in the current travel route, and each of the specified characteristics is specified. Since the evaluation criteria corresponding to the section from the starting point to the first evaluation point in the current travel route is set based on the value, the characteristic value in each route from each starting point candidate and the current starting point to the common first evaluation point Can be used to evaluate the driving operation in the section from the starting point to the first evaluation point on the current travel route. It can be more fair comparison.

  In addition, when the travel route determination unit 13 determines that the current travel route of the vehicle and the past travel route are the same, the evaluation criterion setting unit 14 identifies each route from each departure point candidate to the first evaluation point. Based on the difference between the average value of each characteristic value and the characteristic value specified for the route from the departure point to the first evaluation point on the current travel route, it corresponds to the section from the departure point to the first evaluation point on the current travel route Since the evaluation criteria are set, the interval from the departure point to the first evaluation point in the current travel route is based on the average value of the characteristic values in each route from each departure point candidate and the current departure point to the common first evaluation point. The driving operation can be evaluated, and the past evaluation result and the current evaluation result can be compared more fairly.

Information for specifying the situation or the like is directly acquired from the ECU 2, and based on the acquired information, the evaluation information acquisition unit 11 sequentially determines whether or not the driving operation by the driver is suitable for improving fuel efficiency. You may do it.

(About navigation processing)
In the above-described embodiment, in the navigation process shown in FIG. 2, the evaluation criterion setting unit 14 determines the average value of the characteristic values specified for each route from each departure point candidate to the first evaluation point, and the current travel route. Based on the difference from the characteristic value specified for the route from the departure point to the first evaluation point in, we explained that the evaluation criteria corresponding to the section from the departure point to the first evaluation point in the current travel route will be set. You may set the evaluation reference | standard corresponding to the area from the departure place to the first evaluation point in this driving | running route by a different method.

  For example, the process of SA3 in the navigation process shown in FIG. 2 is omitted, and the vehicle has not traveled in the past on the same travel route as the travel route from the current departure point to the destination set in SA1 (SA2 No), that is, when the vehicle travels for the first time on the travel route from the current departure point to the destination set in SA1, the standard evaluation criterion is the interval from the departure point to the first evaluation point on the current travel route. Set as the evaluation standard corresponding to.

  On the other hand, when the vehicle has traveled in the past on the same travel route as the travel route from the current departure point to the destination set in SA1 (SA2, Yes), SC2 in the evaluation criterion setting process shown in FIG. , The evaluation criterion setting unit 14 specifies the characteristic value specified for the route from the departure point to the first evaluation point in the past driving route, and the characteristic value specified for the route from the departure point to the first evaluation point in the current driving route. Based on the difference, an evaluation standard corresponding to the section from the starting point to the first evaluation point on the current travel route is set. For example, when the travel distance is used as the characteristic value, the evaluation reference setting unit 14 specifies the characteristic value specified for the route from the departure point to the first evaluation point on the past travel route, and the departure point to the first evaluation point on the current travel route. When the difference from the characteristic value specified for the route is -50 m or more and less than 50 m, a predetermined standard evaluation criterion (for example, 90%) is set as the evaluation criterion. When the difference between the characteristic values is 50 m or more and less than 150 m, a value (for example, 95%) obtained by increasing a predetermined standard evaluation criterion by 5% is set as the evaluation criterion. When the difference between the characteristic values is 150 m or more, a value (for example, 100%) obtained by increasing a predetermined standard evaluation criterion by 10% is set as the evaluation criterion. When the difference between the characteristic values is −150 m or more and less than −50 m, a value (for example, 85%) obtained by reducing the predetermined standard evaluation standard by 5% is set as the evaluation standard. When the difference between the characteristic values is less than −150 m, a value (for example, 80%) obtained by reducing the predetermined standard evaluation standard by 10% is set as the evaluation standard.

As described above, when the travel route determination unit 13 determines that the current travel route of the vehicle and the past travel route are the same, the evaluation criterion setting unit 14 determines the distance from the departure point to the first evaluation point on the past travel route. Based on the difference between the characteristic value specified for the route and the characteristic value specified for the route from the starting point to the first evaluation point on the current driving route, it corresponds to the section from the starting point to the first evaluation point on the current driving route Since the evaluation criteria are set, after considering the characteristic values of each route from the previous departure point and the current departure point to the common first evaluation point, in the section from the departure point to the first evaluation point on the current travel route The driving operation can be evaluated, and the past evaluation result and the current evaluation result can be compared more fairly.
