  Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a schematic diagram showing an embodiment of a driving evaluation apparatus according to the present invention.

  As shown in FIG. 1, the driving evaluation apparatus 1 according to the first embodiment includes a car navigation ECU 2 (Electronic Control Unit) provided in a vehicle. A GPS (Global Positioning System) antenna 5, a yaw rate sensor 6, a receiver 7, a database 8, a display 9, and a speaker 10 are connected to the car navigation ECU 2.

  Further, the car navigation ECU 2 includes an engine ECU 11, a brake ECU 12, an EPS ECU 13 (Electronic Power Steering) and other vehicle control ECUs, and an ECU for vehicle electrical control such as CAN (Controller Area Network). Connected by

  The car navigation ECU 2 includes, for example, a CPU, a ROM, a RAM, a data bus that connects them to each other, and an input / output interface. The car navigation ECU 2 performs the following control in accordance with a program stored in the ROM, thereby performing search means 2a. , Display means 2b, update means 2c, determination means 2d, setting means 2d, acquisition means 2e, evaluation means 2f, and notification means 2g.

  The GPS antenna 5 receives radio waves from three satellites among a plurality of satellites launched above the earth. Based on parameters such as the phase difference and arrival time difference of these radio waves, the search means 2a of the car navigation ECU 2 measures the current position where the vehicle is located, that is, the longitude and latitude, for example, based on the principle of triangulation. When measuring altitude as well as longitude and latitude, four satellites are used.

  Here, the yaw rate sensor 6 detects the yaw rate of the vehicle. The database 8 is constituted by a storage medium such as a CD-ROM or a DVD-ROM, and displays the map information for display, the map information for search, and the model driving of the driver of the evaluation means 2f in the traveling within a predetermined period before the previous time. As a result of the evaluation of the degree of enforcement, the starting point and destination of the route R set in the past, the number of passages of the starting point and the destination, the passing points including the starting point and the ending point of the intermediate route RC described later, and the passing of the passing points Various information such as the number of times is stored and stored based on a command from the car navigation ECU 2.

  The display 9 also functions as an input device for inputting a search condition such as a touch panel, that is, a driver inputting a destination, or selecting either the shortest distance or the shortest time without using a highway. . The search means 2a of the car navigation ECU 2 searches based on the map information for search in the database 8 based on the destination and search conditions input by the driver via the display 9 as a touch panel. Information on intersections and signals on R is displayed together with map information for display based on commands from the display means 2b of the car navigation ECU 2.

  Furthermore, the speaker 10 is provided in the vicinity of the display 9 and, based on the control of the display means 2b of the car navigation ECU 2, for example, before the intersection where the vehicle on the route R is scheduled to turn right or left, turn right or left. In addition to outputting the guidance voice of the instruction, based on the control of the notification means 2g of the car navigation ECU 2, the evaluation result of the driver's exemplary driving by the evaluation means 2f of the car navigation ECU 2 and advice based on the evaluation result are included. The sound related to the notification is output.

  The brake ECU 12 includes, for example, a CPU, a ROM, a RAM, a data bus that interconnects them, and an input / output interface. According to a program stored in the ROM, the brake ECU 12 determines the amount of depression caused by a depression operation by a driver of a brake pedal (not shown). Based on this, the brake device (not shown) is controlled to brake the vehicle to give the vehicle deceleration, and the vehicle speed is calculated based on the wheel speed acquired from the wheel speed sensor (not shown). A data frame including vehicle braking information including vehicle speed, stepping amount, and deceleration is transmitted by CAN.

  The EPS ECU 13 includes, for example, a CPU, a ROM, a RAM, a data bus for connecting them to each other, and an input / output interface. The EPS ECU 13 performs each control described below in accordance with a program stored in the ROM, and drives a steering wheel (not shown). Based on the steering force input by the person, the assist force of the steering device that steers the wheel is controlled, and the steering angle for use in assist force control is acquired from a steering sensor (not shown) inside the steering device. The data frame including the steering angle is transmitted to the car navigation ECU 2 by CAN.

  Furthermore, the receiver 7 is compliant with light or radio wave beacons, and receives road information including traffic jam information and signal information from VICS (Vehicle Information & Communication System).

  Thus, the search means 2a of the car navigation ECU 2 calculates the moving distance and direction of the vehicle based on the vehicle speed acquired from the brake ECU 12, the yaw rate detected by the yaw rate sensor 6, and the steering angle transmitted from the EPS ECU 13. The current position of the vehicle is calculated by INS (Inertial Navigation System). The search means 2a of the car navigation ECU 2 is such that the vehicle is located between high-rise buildings, in tunnels, mountains, etc., and it is difficult for the GPS antenna 5 to sufficiently receive radio waves from the satellite. When the current position of the vehicle cannot be measured, the current position of the vehicle calculated by INS is used complementarily.

  The display means 2b of the car navigation ECU 2 includes map information for display in the database 8, the current position of the vehicle obtained by the above-described method, the destination input by the touch panel, that is, the display 9, and search means. The route R searched by 2a and the information related to the route R are displayed together on the display 9.

  At the same time, the car navigation ECU 2 stores the position information in the database 8 after actually traveling through the starting point and the destination of the route R. Whether or not the vehicle has actually passed through the destination is detected by detecting on the CAN whether or not the ignition key ACC (indicating the accessory position of the ignition key. It can be substituted even when turned off) is turned on.

  Here, the engine ECU 11 is composed of, for example, a CPU, a ROM, a RAM, and a data bus and an input / output interface for interconnecting them. According to a program stored in the ROM, an engine fuel injection amount, throttle opening, While controlling engine speed etc., the data frame containing these vehicle control information is transmitted to car navigation ECU2 by CAN.

  Further, the determination means 2c of the car navigation ECU 2 reads out the first predetermined distance D1 and the second predetermined distance D2 stored in advance in the database 8 of the car navigation ECU 2, and inputs the input destination and search conditions, And the current position of the vehicle at the time when the search condition is input by the driver, that is, the departure point, and the range from the route R searched by the search means 2a to a point on the route R separated by the first predetermined distance D1 from the departure point. And calculating the end route RE located within the range from the destination to a point on the route R separated by the second predetermined distance D2 from the destination, and obtaining the start route RS and the end route RE from the route R. The remaining section is set as the intermediate route RC. Here, both the first predetermined distance D1 and the second predetermined distance D2 are 300 m.

  For example, when the home and the company exist in a positional relationship as shown in FIG. 2, the area A indicates a range from the home to a point on the route R that is a first predetermined distance D1 away from the home. The end point ◯ 1 that is the intersection of the outer edge and the searched route R is set as the start or end of the intermediate route RC. Area B indicates the range from the company to the point on the route R that is a second predetermined distance D2 away from the company, and the end point ○ 2 that is the intersection of the outer edge of the area B and the searched route R is the start point of the intermediate route RC Or the rear end.

  For example, when there are a plurality of end points ○ 1 due to the existence of a plurality of searched routes R, the end points ○ that are 300 m from the home stored in the database 8 in the past run. 3 is the table A shown in FIG. 3, and the place where the ignition key position stored in the past driving is ACC, that is, the destination pass number of the candidates for the destination is the table B shown in the upper side of FIG. In the case where the number of passes in the past travel of the end point ○ 2, which is a point that has passed 300 m from the coordinate (X4, Y4) which is the first rank in the upper side of FIG. 4, is the table C shown on the lower side of FIG. Performs the following controls:

  That is, the determination means 2c of the car navigation ECU 2 selects the coordinate (X1, Y1) with the highest number of passes as the end point ○ 1 in the table A shown in FIG. 3, and has the highest number of passes in the table B shown on the upper side of FIG. The coordinates (X4, Y4) are selected as the destination, the coordinates (X7, Y7) with the largest number of passages are selected as the end points ○ 2 from the table C shown in the lower part of FIG. 4, and then the table D shown in FIG. Among the routes connecting the end points ○ 1 and ○ 2, the route including the link 1 → link 2 → link 3 having the highest number of passages is selected as the intermediate route RC.

In this way, the determination unit 2c determines whether or not the vehicle has traveled a predetermined frequency or more on the intermediate route RC that is a partial route including the route R connecting the departure point and the destination. Here, the predetermined frequency or more indicates that the number of times of passage through the intermediate route RC within the predetermined period, that is, the number of travels is equal to or more than the predetermined number ( 108 times in the table D shown in FIG. 5).

  That is, the determination unit 2c determines the intermediate route RC to be equal to or more than a predetermined frequency based on the comparison with the tables shown in FIG. 3 to FIG. 5, which is the number of travels of the intermediate route RC stored in the database 8 in the past travel period. It is determined whether or not the vehicle has traveled. When the determination unit 2c determines affirmative, the setting unit 2d of the car navigation ECU 2 sets the intermediate route RC that has been determined to be affirmative as the evaluation section.

  The tables shown in FIGS. 3 to 5 are all cleared when the home registration in the car navigation ECU 2 is re-registered or updated, and the past data for a predetermined period or more from the present is also discarded at any time. And Further, the route shown in FIG. 2 is not treated as the same route, but is treated as a different route, and the priority of the end point ○ 1 shown in FIG. 3 or the priority order of the end point ○ 2 shown in FIG. 4 is changed. Clear tables C and D. Further, in the case where the home and the company are switched in the positional relationship shown in FIG. 2, the data on the upper side of FIG.

  The acquisition unit 2e of the car navigation ECU 2 acquires vehicle travel information during a period in which the vehicle is traveling in the evaluation section. The travel information is acquired from the vehicle ECU information such as the fuel injection amount, throttle opening, and engine speed acquired from the engine ECU 11, the vehicle brake information such as the brake pedal depression amount and deceleration acquired from the brake ECU 12, and the EPS ECU 13. Steering angle, direction indication information acquired on CAN, link information included in map information for search read out from database 8, position of temporary stop line included in link information, position of intersection, position of intersection from receiver 7 Contains signal information.

  The evaluation means 2f of the car navigation ECU 2 evaluates the degree of enforcement of the exemplary driving of the vehicle based on the travel information acquired by the acquisition means 2e. Model driving means, for example, forcing a stop before the stop line, observing a signal, observing an appropriate acceleration, observing an appropriate deceleration, observing an appropriate steering operation, and decelerating before an appropriate turn. It refers to general driving operations that lead to improved fuel economy and safety.

  Further, the non-exemplary operation refers to an operation mode in which the above-described exemplary operation is not performed. For example, the evaluation means 2f is referred to as a temporary stoppage failure when the vehicle has entered the intersection without temporarily stopping on the stop line after the searched vehicle position is before the intersection including the stop line. It is evaluated that non-exemplary driving occurs and the degree of enforcement of exemplary driving is low. Similarly, when the signal at the intersection in front of the vehicle is red, when the vehicle enters the intersection without stopping, an out-of-execution operation such as a signal compliance failure occurs, which is also a low degree of implementation of the exemplary operation. And evaluate.

  Similarly, when the driver depresses the accelerator pedal excessively and the throttle opening becomes excessively large, the evaluation means 2f generates an extra driving example of excessive acceleration driving, and encourages the driving of the driving example. Assess that the degree is low. In addition, if the driver does not fully depress the brake pedal in front of the curve, the evaluation means is performing an off-execution operation such as a deceleration operation failure before turning. Assess that the degree is low.

  More specifically, the evaluation means 2f adds three points if the exemplary driving is being carried out near the intersection, the pedestrian crossing, or in front of the curve, which is the target of the exemplary driving in the intermediate route RC. When non-exemplary driving is performed, one point deducted by two points is added, the total score in the intermediate route RC is calculated, the total score indicating the degree of driving of the exemplary driving, the type of non-exemplary driving, Together with the point where the non-exemplary operation is performed, the database 8 stores the result as an evaluation result in association with the intermediate circuit RC.

  Further, the notification unit 2g of the car navigation ECU 2 performs notification based on the evaluation result of the evaluation unit 2f by text or graphics on the display 8, symbol display, or heart-full voice of the speaker 10.

  Note that the content of the notification includes a total score and a content that informs that the non-exemplary driving has been performed and encourages the exemplary driving. For example, when a temporary stoppage is performed at a point as a non-executive operation, a notice “Please observe the suspension at the point ●” is given and appropriate acceleration is not enforced. In the case of a notice, “please refrain from suddenly depressing the accelerator pedal.” If the appropriate deceleration is not complied with, “please refrain from sudden braking.” If appropriate steering operation is not carried out, a message “Please refrain from sudden steering operation” is notified.

  In addition, about the timing which the notification means 2g performs a notification, the notification means 2g will notify after a vehicle arrives at the terminal of an evaluation area. A specific method for performing notification at any point from the end of the evaluation section to the destination can be, for example, as follows.

  As shown in FIG. 6, when the destination is the home P1 in the area A shown in FIG. 2 and there are a plurality of road links around the home, the evaluation result, evaluation content, and advice are displayed from the start of the notification. The notification start timing is set so that the timing at which the notification is completed after the time necessary for the notification to be included is the timing at which the vehicle passes just before the home.

  In this case, the determination means 2c of the car navigation ECU 2 stores the link information outside the evaluation section around the home P1, that is, in the area A, and the location information of the convenience store P3 and the bookstore P2 that can serve as a trigger before returning home in the database 8. Read from the map information.

  Further, the determination means 2c uses a route candidate table that can be connected to the points P1 to P5 in the area A as shown in FIG. When a vehicle that has entered the area A through the end P5 of the evaluation section passes the link A in FIG. 6 and then enters the link B, the route candidate of the end route RE reaching the P3 or P4 is excluded. When entering the link C, the route candidate of the end route RE leading to P2 is also excluded, and after the vehicle reaches and passes through the end of the evaluation section, the vehicle moves to the convenience store P3 or the outer edge of the area A. It is determined that it is determined that the user has reached the home P1 without stopping at the point P4 and the bookstore P2.

  When the determination unit 2c determines that the vehicle has reached home, the notification unit 2g of the car navigation ECU 2 starts notification.

  Further, in the driving evaluation device 1, the start route RS within the first predetermined distance D1 range from the departure point and the end within the second predetermined distance D2 range from the destination among the routes R connecting the departure point and the destination with the partial route. The determination unit 2c sets the intermediate route RC so as to be the intermediate route RC excluding the route RE, and this has the following significance.

  That is, the start route RS within the first predetermined distance D1 range from the departure point and the end route RE within the second predetermined distance range D2 from the destination tend to be changed every driving day even for the same driver. The intermediate route RC has a property that it is less prone to change when there is no special circumstances such as the opening of a new road. Therefore, using this property, the start route RS and the end route RE are different from each other. An intermediate route RC common to the route R is extracted and utilized as effectively as possible. In the first embodiment, the first predetermined distance D1 and the second predetermined distance D2 are fixed values of 300 meters.

  In other words, in the first embodiment, when the departure place is a home and the destination is a company, a vehicle stops irregularly and irregularly before coming to a store such as a convenience store around the company. Or, by selecting and using a plurality of parking lots in the company site for each operation day for business reasons, the intermediate route RC can be used for each operation day even if the end route RE is different for each operation day. In view of the fact that there is often no difference between the two routes R, an intermediate route RC common to a plurality of routes R having different start routes RS and end routes RE is set and used as an evaluation section.

Similarly, when returning home, where the departure point is a company and the destination is home, vehicles stop regularly and irregularly before returning home to convenience stores, supermarkets, video rental stores , bookstores, etc. Even if, for example, the home route is a company house or the like, and a plurality of parking lots in the site in the company house are selected and used for each driving day, the end route RE may be different for each driving day, The intermediate route RC is set and used as an evaluation section in consideration of the fact that the intermediate route RC does not often vary from driving day to driving day.

  Furthermore, at the time of leaving the office, the intermediate route RC may differ from driving day to driving day, even if road construction points and traffic congestion points differ depending on the driving day, for example, on roads from residential areas including homes or urban areas to the main roads leading to the company. Considering that there are many cases where the intermediate route RC is not used, the intermediate route RC is set as an evaluation section and used. On the road from the industrial estate including the company or the main road to the home when leaving the office, for example, even if the road construction location and the location where the traffic jam occurs vary depending on the driving day, the intermediate route RC should not differ from driving day to driving day. Considering that there are many, the intermediate route RC is set as an evaluation section and used.

  The control content of the driving | running evaluation apparatus 1 of the present Example 1 described above is demonstrated using a flowchart. FIG. 8 is a flowchart showing the control contents of the driving evaluation apparatus 1 according to the present invention.

  As shown in FIG. 8, after the driver inputs a search condition including the destination on the display 9 in step S1, the search means 2a of the car navigation ECU 2 measures the current position of the vehicle, that is, the departure place in step S2. In step S3, a plurality of route R candidates from the departure point to the destination are searched.

  Subsequently, in step S4, the determination unit 2c of the car navigation ECU 2 reads the first predetermined distance D1 and the second predetermined distance D2, calculates the start route RS and the end route RE for each of a plurality of route R candidates, In S5, a plurality of intermediate route RC candidates are set by excluding the corresponding start route RS and end route RE from the plurality of route R candidates.

  Furthermore, in step S6, the determination unit 2c of the car navigation ECU 2 determines whether there is an intermediate route RC that has traveled more than a predetermined frequency in the past travel among candidates for the intermediate route RC. Proceed to step S7, and if negative, proceed to step S14.

  In step S7, the setting unit 2d of the car navigation ECU 2 sets the intermediate route RC that has been affirmed in step S7 and has traveled more than a predetermined frequency as an evaluation section. In step S8, the determination means 2c of the car navigation ECU 2 determines whether or not the current position of the vehicle measured by the search means 2a of the car navigation ECU 2 has reached the set intermediate route RC, that is, the start of the evaluation section. If YES, proceed to step S9. If NO, proceed to RETURN.

  In step S9, the acquisition means 2e of the car navigation ECU 2 acquires vehicle travel information in the evaluation section, and in step S10, the evaluation means 2f of the car navigation ECU 2 evaluates the driving degree of the exemplary driving of the vehicle in the evaluation section. .

  In step S11, the determination means 2c of the car navigation ECU 2 determines whether or not the current position of the vehicle measured by the search means 2a of the car navigation ECU 2 has reached the set intermediate route RC, that is, the end of the evaluation section. If YES, the process proceeds to step S12. If NO, the process returns to the position before step S9.

  In step S12, the notification means 2g of the car navigation ECU 2 notifies the driver of the contents based on the result of the evaluation. In step S13, the evaluation means 2f of the car navigation ECU 2 detects the intermediate route RC and the starting end set in the evaluation section, The number of times of passage at the end, that is, the number of times of travel and the number of times of passage of the destination based on the ACC operation after reaching the destination are counted and stored in the database 8 in association with the intermediate route RC.

In step S14, the determination means 2c of the car navigation ECU 2 determines whether or not the current position of the vehicle measured by the search means 2a of the car navigation ECU 2 has reached the starting end of the set intermediate route RC. If yes, proceed to step S15. If not, proceed to RETURN.

In step S15, the determination means 2c of the car navigation ECU 2 determines whether or not the current position of the vehicle measured by the search means 2a of the car navigation ECU 2 has reached the end of the set intermediate route RC. If there is, proceed to Step S16, and if not, proceed to RETURN.

  In step S16, the evaluation means 2f of the car navigation ECU 2 determines the intermediate route RC that has not been set in the evaluation section and the number of times of passage at the start and end, that is, the number of times of travel, and the number of times of passage of the destination based on the ACC operation after reaching the destination. Count and associate with the intermediate route RC and store in the database 8.

  The flowchart of FIG. 8 described above is repeatedly executed every calculation cycle of the car navigation ECU 2, the determination step in the driving evaluation method of the present invention is executed in step S6, the setting step is executed in step S7, and the obtaining step is executed in step S9. Is executed, an evaluation step is executed in step S10, and a notification step is executed in step S12.

  According to the driving evaluation apparatus 1 of the first embodiment that is executed by the above control, the following operational effects can be obtained.

  That is, in the driving evaluation apparatus 1 of the first embodiment, the intermediate route RC that is a partial route that is a part of the route R that the vehicle is traveling over a predetermined frequency and can be regarded as traveling on a daily basis is evaluated. As a section, the acquisition unit 2e acquires travel information for each evaluation section, and the evaluation unit 2f can evaluate the driving degree of exemplary driving of the vehicle based on the acquired travel information.

  That is, when the travel frequency is low, the intermediate route RC is not set as the evaluation section, so that the notification of the evaluation result to the vehicle driver is not performed on the intermediate route RC with the low travel frequency. It can be. As a result, notifications that are unnecessary or not desired by the driver are performed, so that the driver of the vehicle feels bothered and uncomfortable, and the driver avoids or avoids using the driving evaluation device 1, It can be prevented that the usage frequency of the driving evaluation device 1 is reduced and it is difficult for the driver to effectively perform the exemplary driving as a result.

  When the determination unit 2c determines whether the vehicle has traveled the intermediate route RC that is a partial route including the route R connecting the departure point and the destination, the predetermined number of times is set as a predetermined constant. Alternatively, the maximum number of times of traveling for each candidate of the intermediate route RC may be updated to a predetermined number as needed. Moreover, although the frequency | count of driving | running | working is limited to the frequency | count of driving | running | working in the predetermined period from now, this predetermined period can also be changed suitably.

  In addition, when the location of the driver's company is changed due to relocation, change of job, etc., when the home location is changed due to moving, etc., even when the route R and the intermediate route RC are changed. When the intermediate route RC is traveled a predetermined number of times within a predetermined period, the changed intermediate route RC is automatically set as the evaluation section, so that the setting of a separate evaluation section by the driver is abolished. Thus, the convenience of the driver can be improved and the usage frequency of the driving evaluation device 1 can be increased. This can further increase the degree of enforcement of the exemplary driving.

  In addition, since the driving evaluation apparatus 1 of the first embodiment includes the notification unit 2g that performs notification based on the evaluation result of the evaluation unit 2f, the driver feels bothered by the evaluation unit 2f. Notification can be given after avoiding getting uncomfortable, and the driving degree of the model driving can be perceived, the driving of the model driving can be recommended, and the driving evaluation device 1 is continuously used by the driver. This can encourage the driver to effectively perform exemplary driving.

  In particular, since the notification means 2g performs notification on the end route RE, the notification can be terminated before reaching the destination, so that the driver can be notified and the time required for the notification can be obtained. Accordingly, it is possible to prevent the driver from feeling annoyed and increase the usage frequency of the driving evaluation device 1. As a result, it is possible to more effectively encourage exemplary driving.

  Further, in the driving evaluation device 1 of the first embodiment, the notification means 2g notifies the driver after the vehicle reaches the end of the evaluation section, so that the driving degree of the exemplary driving is determined to the driver of the vehicle. When notifying the result, the driver needs to be extra restrained by the time required for the driver to hear or view the content of the notification, compared to the notification after the vehicle has arrived at the destination. It is possible to prevent the driver from being bothered and uncomfortable. This also increases the frequency of use of the driving evaluation device 1 and can more effectively encourage exemplary driving.

  Further, as shown in FIG. 6, when the destination is the home P1 in the area A shown in FIG. 2 and there are a plurality of road links around the home, the evaluation result, evaluation from the start of notification By setting the notification start timing so that the timing at which the notification, including the content and advice, elapses after the time necessary for the notification has passed, is the timing at which the notification passes immediately before the home, Immediately before the end of driving, which is unlikely to be an obstacle to ensuring safety for the driver, it is possible to prevent the driver from being bothered and uncomfortable, and the driving evaluation device 1 The frequency of use can be increased to encourage more effective driving.

  Furthermore, in the driving evaluation apparatus 1 of the first embodiment, the start route RS within the range of the first predetermined distance D1 from the departure point and the second predetermined distance from the destination among the routes connecting the departure point and the destination in the partial route. Since the intermediate route RC excluding the end route RE within the D2 range is used, the common intermediate route RC between the routes R having different start routes RS or different end routes RE is extracted, and the extracted intermediate route RC is used as the evaluation section. It can be set and used effectively.

  In other words, as described above, the intermediate route RC is determined in consideration of the fact that the intermediate route RC is often common even when the departure point, the start route RS, the destination, and the end route RE are different for each operation day. Since the setting means 2d sets as the evaluation section, the acquisition means 2e acquires the vehicle travel information on the intermediate route RC, and the evaluation means 2f evaluates the driver's exemplary driving performance based on the travel information. As information is acquired only in the intermediate section RC useful in the evaluation of the evaluation means 2f, the processing load on the car navigation ECU 2 constituting the acquisition means 2e is reduced, and the evaluation results in different driving days are used more effectively. Can do.

  In addition, in the driving | running evaluation apparatus 1 of the present Example 1, although the 1st predetermined distance D1 and the 2nd predetermined distance D2 are taken as the fixed value of about 300 meters or several hundred meters, it is set and updated at any time based on map information. It may be a value. In the first embodiment, the search means 2a preferentially searches the route R so as to include the evaluation section so that the driver can trace the evaluation section once set as much as possible in the subsequent driving. However, it may be configured to determine whether or not the evaluation section is already set and to preferentially search for the route R including the evaluation section when the evaluation section is already set. The second embodiment will be described below.

  FIG. 9 is a schematic diagram showing an embodiment of the driving evaluation apparatus according to the present invention.

  As shown in FIG. 9, the driving evaluation device 1 of the second embodiment is configured by a car navigation ECU 2 provided in a vehicle. A GPS antenna 5, a yaw rate sensor 6, a receiver 7, a database 8, a display 9, and a speaker 10 are connected to the car navigation ECU 2.

  Furthermore, an engine ECU 11, a brake ECU 12, and an EPS ECU 13 are connected to the car navigation ECU 2 according to a communication standard such as CAN. Note that the components connected to the car navigation ECU 2 of the second embodiment described above are the same as those shown in the first embodiment, and thus descriptions of the overlapping individual configurations and functions are omitted.

  The car navigation ECU 2 includes, for example, a CPU, a ROM, a RAM, a data bus that connects them to each other, and an input / output interface, and performs search similar to that described in the first embodiment in accordance with a program stored in the ROM. It functions as means 2a, display means 2b, determination means 2c, setting means 2d, acquisition means 2e, evaluation means 2f, notification means 2g, and also functions as update means 2h for executing the control described below.

The updating means 2h of the car navigation ECU 2 in the driving evaluation device 1 of the second embodiment updates the second predetermined distance D2 based on the map information included in the destination and the database 8 around the destination, and the first predetermined distance D1. Is updated based on the map information of the departure point and the vicinity of the departure point.

  More specifically, when the departure place is a home and the home belongs to a residential area where houses are densely populated, the route R from the road in the residential area and the road connecting the residential area and the main road to the destination R Since the transition point that shifts to the upper trunk road can be determined from the link information included in the map information, the updating unit 2h performs update processing to set the distance between the transition point and the home as the first predetermined distance D1 as needed.

  Similarly, since the destination is a company and the transition point from the main road on the route R leading to the company to the road in the vicinity of the company can also be determined from the link information included in the map information, the updating means 2h Update processing is performed as needed to set the distance between the transition point and the company to the second predetermined distance D2. The update process is similarly performed when the departure place is a company and the destination is at home.

  Further, the driving evaluation device 1 of the second embodiment includes the search means 2a for searching for the route R, and after the setting means 2d sets the evaluation section, the search means 2a preferentially selects the route including the evaluation section. I am going to explore.

  In step S17, the determination means 2c of the car navigation ECU 2 determines whether or not the evaluation section has already been set in step S7 in the previous time, and if negative, proceeds to step S3 to search for a route, and if positive. In step S18, the route R including the preset evaluation section is preferentially searched.

  In step S19, the updating means 2h of the car navigation ECU 2 updates the values of the first predetermined distance D1 and the second predetermined distance D2 in the database 8 based on the current starting point and destination positions and map information. . In step S19, an update step of the driving evaluation method of the present invention is executed.

  According to the operation evaluation apparatus 1 of the second embodiment described above, the following functions and effects can be obtained in addition to the functions and effects shown in the first embodiment.

  That is, including the updating means 2h, the values of the first predetermined distance D1 and the second predetermined distance D2 are updated at any time based on the current starting point, the destination, and the map information. In addition, it can be updated as needed along with the change of the destination, so that it is possible to set a more appropriate section in executing the acquisition of the travel information and the evaluation of the driving performance of the exemplary driving.

  Further, the area A or B is determined by the first predetermined distance D1 or the second predetermined distance D2, which is a fixed value, starting from the home or office, etc., the start route RS and the end route RE are calculated, and the intermediate route RC is calculated. In contrast, even if the home or company is different between different drivers, if the home belongs to area A and the company belongs to area B, Since it is easy to make common, it is possible to make the evaluation section as common as possible by making the start and end of the intermediate route RC coincide as much as possible even in different drivers.

  Furthermore, once the evaluation section has been set, it is recommended that the route R including the evaluation section be continuously presented to the driver, and it is recommended to continuously travel in the evaluation section before the previous time. It is possible to increase the number of evaluations of the driving execution degree and to make the evaluation of the improvement degree of the driving degree easier.
