[Real-time driving diagnosis]
First, real-time driving diagnosis will be described with reference to FIGS.

As described above, in the real-time driving diagnosis, a plurality of diagnosis items are diagnosed, and each of the plurality of diagnosis items is classified into the classification type shown in FIG.
Specifically, it is classified into (1) traveling section comparison type, (2) quantitative determination possible type, and (3) stop event generation type according to the nature of the diagnosis target. Hereinafter, each classification type will be described.
(1) Travel Section Comparison Type The diagnostic items classified as the travel section comparison type are as follows. Specifically, it is a diagnostic item suitable for relatively evaluating pass / fail by comparing diagnosis results between predetermined travel sections (travel distances) rather than quantitatively evaluating pass / fail. That is, the item is more suitable for relative evaluation than absolute evaluation.

  The diagnostic items classified into this travel section comparison type will be described in detail later. For example, eco lamp lighting travel diagnosis, eco switch (hereinafter referred to as eco SW) use travel diagnosis, air conditioner use diagnosis, accelerator off There are travel diagnosis, eco-guided travel diagnosis, and so on. The eco lamp is a lamp that is turned on when the running state of the vehicle is an economical state (for example, a state in which fuel consumption is suppressed). The eco switch is a switch for switching the driving mode of the vehicle to the low fuel consumption mode. In the low fuel consumption mode, for example, the operating state of the air conditioner is suppressed from the normal time, or the rate of increase of the fuel injection amount with respect to the accelerator depression amount is suppressed from the normal time, thereby reducing the fuel consumption.

  In the eco lamp lighting travel diagnosis, the ratio of the distance traveled by the vehicle while the eco lamp is lit (that is, the ratio of the distance traveled by the vehicle in an economical travel state) is calculated within a predetermined travel section (travel distance). The

  In the travel diagnosis using eco-SW, the ratio of the distance traveled by the vehicle while the eco-SW is effective (that is, the ratio of distance traveled by the vehicle in the low fuel consumption mode) in a predetermined travel section (travel distance) is calculated. The

In the air conditioner use diagnosis, the ratio of the air conditioner usage time is calculated out of the time during which the vehicle can travel in a predetermined travel section.
In the accelerator-off travel diagnosis, a ratio of a distance traveled only by inertia in a state where the accelerator is off (specifically, the amount of depression of the accelerator is 0) in a predetermined travel section (travel distance) is calculated. The accelerator depression amount is calculated based on a signal from an accelerator sensor for detecting the accelerator depression amount.

In the eco-guided travel diagnosis, the ratio of the distance traveled using a route guidance service for avoiding a traffic jam route with respect to the distance from a predetermined point to the destination is calculated.
(2) Quantitative Judgment Type Diagnostic items classified as Quantitative Judgment Type are as follows. Specifically, it is a diagnostic item related to safety and is a diagnostic item capable of quantitatively evaluating quality (suitable for quantitatively evaluating quality). Also, diagnostic items for diagnosing events (phenomena) that occur relatively frequently are also classified into this type.

  Details of the diagnostic items classified into this quantitative determination type will be described later. For example, speed limit diagnosis, accelerator diagnosis, brake diagnosis, temporary stop diagnosis, inter-vehicle distance diagnosis, seat belt wear diagnosis, light in tunnel There are lighting diagnosis and early light lighting diagnosis.

  In the speed limit diagnosis, the ratio of the distance traveled exceeding the speed limit in a predetermined travel section (travel distance) is calculated. The calculation result is evaluated based on the reference value for this diagnosis. The speed limit information can be obtained by analyzing a road marking image taken from a camera (not shown) provided in the vehicle. In addition, the VICS information receiving device 13 can receive the information from a fixed station for VICS service. Moreover, if the information regarding traffic regulation is memorize | stored in the map database 11, it can also be made to acquire from the map database 11. The speed of the vehicle is calculated based on a signal from a vehicle speed sensor.

  In accelerator diagnosis, the acceleration scene is identified from the vehicle state, and the ratio of the number of occurrences of the scene where the acceleration and jerk (rate of change of acceleration) before and after the scene exceed the threshold with respect to the total number of occurrences of the acceleration scene is Calculated. The calculation result is evaluated based on the reference value for this diagnosis. In addition, you may make it evaluate by calculating the ratio of the distance which drive | worked in the state in which the accelerator (illustration omitted) was stepped on more than predetermined amount among predetermined traveling sections (travel distance).

  In the brake diagnosis, the number of so-called sudden braking is calculated. The calculation result is evaluated based on the reference value for this diagnosis. Whether the brake is sudden or not is determined based on signals from the brake sensor and the acceleration sensor. For example, the operation amount of the brake pedal calculated based on the signal from the brake sensor is determined based on whether or not the amount of change per predetermined time of the operation amount is equal to or greater than a predetermined amount. Alternatively, the determination is made based on whether or not the deceleration amount calculated based on the signal from the acceleration sensor is equal to or greater than a predetermined amount.

  In the pause diagnosis, it is diagnosed whether or not a pause has been made at a location to be paused. It should be noted that it is possible to determine whether or not the location is to be temporarily stopped based on traffic information received from the VICS service fixed station by the VICS information receiving device 13. Moreover, if the information regarding traffic regulation is memorize | stored in the map database 11, it can also judge based on the information.

  In the inter-vehicle distance diagnosis, in a predetermined travel section (travel distance), the vehicle travels in a state where the distance (that is, the inter-vehicle distance) with another vehicle traveling in front of the host vehicle is equal to or greater than the predetermined distance in the same travel lane as the host vehicle. The ratio of the distance is calculated. The calculation result is evaluated based on the reference value for this diagnosis.

  In the seat belt wearing diagnosis, it is diagnosed whether or not the seat belt is worn based on a signal from a sensor that is provided on the seat belt and detects attachment / detachment of the seat belt. More specifically, it is diagnosed whether the seat belt is worn when the vehicle shift range (not shown) is set to a state other than P, R, and N and the vehicle speed is equal to or higher than a predetermined speed.

  In the tunnel light lighting diagnosis, it is diagnosed whether or not the light is turned on in the tunnel. Whether or not the vehicle is traveling in the tunnel (whether or not the vehicle has entered the tunnel) is determined based on a signal from the illuminance sensor. The determination can also be made based on the current position of the vehicle calculated by the GPS receiver 12 and the road data stored in the map database 11.

In the early light lighting diagnosis, it is diagnosed whether the light has been turned on in a recommended time zone. The recommended time zone is determined based on the latitude / mildness of the current location and the sunset time calculated from the date and time.
(3) Event generation type at stop The diagnostic items classified as event generation type at stop are as follows. Specifically, the diagnostic item is diagnosed with respect to the environment when the vehicle is stopped or while the vehicle is stopped, and is a diagnostic item for diagnosing an event (phenomenon) having a relatively high occurrence frequency.

The diagnosis items classified into the event generation type at the time of stopping are described later in detail, and include, for example, an empty check diagnosis and an idle idle time diagnosis.
In the vacancy diagnosis, it is diagnosed whether or not vacancy has been made when the vehicle is stopped or while the vehicle is stopped.

In the idle idle time diagnosis, it is diagnosed whether the duration time of the idle state exceeds a predetermined time when the vehicle is stopped or during the stop.
Here, as shown in FIG. 3, priorities are defined in advance for the classification types (1) to (3). Specifically, the priority of the event generation type at the time of stopping is the highest, the priority of the type capable of quantitative determination next is the highest, and the priority of the travel section comparison type is the lowest. How the priority is used will be described later.

Next, FIG. 4 is a flowchart showing advice generation processing executed in the real-time advice generation unit 153 of the control circuit 115.
The advice generation process of FIG. 4 is executed at a predetermined timing after the driving diagnosis information providing apparatus 10 is activated. Although the predetermined timing will be described in detail later, the advice generation timing for the travel section comparison type diagnosis item, the advice generation timing for the quantitative judgment type diagnosis item, and the advice regarding the event generation type diagnosis item at the time of stoppage are provided. Generation timing. Each generation timing may or may not overlap. For this reason, all of S110 to S130 or any two of the processes may be executed in parallel, or only one of S110 to S130 may be executed.

In S110, based on the diagnosis result of the stop event occurrence type diagnosis item, advice on the diagnosis item is generated.
In S120, based on the diagnosis result for the quantitative judgment type diagnostic item, advice on the diagnostic item is generated.

In S130, based on the diagnosis result of the travel section comparison type diagnosis item, advice on the diagnosis item is generated.
After S110 to S130, the process proceeds to S140.

  In S140, it is determined whether or not a plurality of advices are generated at the same time. If a plurality of advices are generated at the same time, a maximum of two items are ordered in descending order of priority according to the priority described in FIG. Choose advice.

  After S140, the process proceeds to S150, and an advice ID corresponding to the selected advice is output. The advice ID is assigned according to the advice, and is stored as table information in the external memory 108, for example. In S150, an advice ID corresponding to the selected advice is output. The advice ID is recognized by the control circuit 115 and the advice corresponding to the advice ID is displayed on the display screen of the display device 109.

FIG. 5 is a time chart showing diagnosis timing and advice generation timing (execution timing of execution of advice generation processing) in real-time driving diagnosis.
In FIG. 5, the first level represents the on / off state of the accessory switch (ACC) of the vehicle.

  The second level represents an example of the running / stopped state of the vehicle, and each of the sections (1) to (8) represents a section in which the vehicle is traveling (section where the vehicle speed is greater than 0 km / h). The section represents a section where the vehicle is stopped (vehicle speed is 0 km / h). In addition, the numerical value of km display attached | subjected for every area represents travel distance.

The third level represents the diagnosis timing of the driving state.
In the present embodiment, the diagnosis is performed with a predetermined interval as one unit. Specifically, starting from a point where the cumulative travel distance of the vehicle is 0, the first stop time after the cumulative travel distance of the vehicle is 1.6 km or more is the end point, and the unit from the start point to the end point is 1 unit. Become. Hereinafter, this one-unit section is also referred to as an evaluation section. In addition, 1.6 km is an average travel distance (statistically known) when the vehicle is driven with a so-called “slightly riding” feeling (feeling that a little).

  In the example of FIG. 5, after the accessory switch is turned on, the point at which the vehicle first starts running (the start point of the section (1)) becomes the start point of the evaluation section. At the end point of section (1), the cumulative travel distance is 0.8 km and does not satisfy the condition that it is 1.6 km or more, so it is not the end point of the evaluation section. Similarly, the end point of section (2) is also Since it does not satisfy the condition that the cumulative travel distance is 1.5 km and is 1.6 km or more, it does not become the end point of the evaluation section. The end point of section (3) satisfies the condition that the cumulative travel distance is 2.2 km and is 1.6 km or more (in other words, the end point of section (3) is that the cumulative travel distance is 1.6 km or more) Since this is the first stop position after becoming), it becomes the end point of the evaluation section. That is, the start point of the section (1) to the end point of the section (3) is the first evaluation section (hereinafter referred to as the first evaluation section). Diagnosis is performed for the first evaluation interval. The diagnosis timing is the end point of the first evaluation interval (that is, the end point of the interval (3)).

  The next evaluation section (hereinafter referred to as a second evaluation section) is from the end point of section (3) to the end point of section (5). The diagnosis timing for the second evaluation interval is the end point of the second evaluation interval (that is, the end point of the interval (5)).

  Further, the next evaluation section (hereinafter referred to as a third evaluation section) is from the end point of the section (5) to the end point of the section (7). The diagnosis timing for the third evaluation interval is the end point of the third evaluation interval (that is, the end point of the interval (7)).

  The fourth level represents advice generation timing (execution timing of advice generation processing) for diagnostic items classified as a travel section comparison type. Here, the diagnosis result in the previous evaluation section and the diagnosis result in the current evaluation section are compared, the present diagnosis result is relatively evaluated, and advice based on the evaluation result is generated. For this reason, no advice is generated at the end point of the first evaluation section because there is no diagnosis result of the previous evaluation section (the previous evaluation section does not exist). On the other hand, at the end point of the second evaluation interval, the diagnosis result of the first evaluation interval and the diagnosis result of the second evaluation interval are compared, and the diagnosis result of the second evaluation interval is relatively evaluated to generate advice. Is done. The same applies to the third evaluation section. Specifically, the diagnosis result of the third evaluation section and the diagnosis result of the second evaluation section are compared, and the diagnosis result of the third evaluation section is relatively evaluated to generate advice.

  The fifth row represents advice generation timing (execution timing of advice generation processing) regarding a diagnosis item classified as a quantitative judgment possible type. Regarding the diagnostic items classified into the quantitative determination type, advice based on the diagnosis result of the evaluation section is generated at the end of the evaluation section as described above. In the example of FIG. 5, advice is generated at each of the end point of the section (3), the end point of the section (5), and the end point of the section (7), which are the end points of the evaluation section.

The sixth row represents an example of the occurrence timing of events that can occur when the vehicle is stopped.
The seventh row represents the diagnosis timing when the vehicle is stopped. When the vehicle stops, sampling is performed every 1 s interval to diagnose the occurrence of an event. Specifically, at the end point of the sections (1) to (8), that is, at the timing when the vehicle stops, diagnosis of an event generation type diagnosis item at the time of stop is performed, and thereafter, diagnosis is performed every 1 s.

  The eighth row represents the advice generation timing for the diagnostic item classified as a stop event generation type. Regarding diagnosis items classified as an event generation type at the time of stopping, when an event occurs while the vehicle is stopped (when it can be diagnosed that an event has occurred), advice generation processing (FIG. 4) Advice) is generated.

  In the travel section comparison type, for example, during the third evaluation section, advice on the second evaluation section is continuously generated until the cumulative travel distance of the third evaluation section becomes 1.6 km or more. (Generated when the vehicle is stopped). Similarly, in the quantitative determination type, for example, in the middle of the second and third evaluation sections, the previous evaluation section is continued until the cumulative travel distance of the second and third evaluation sections becomes 1.6 km or more. Advice about the first and second evaluation sections is generated (generated when the vehicle is stopped). Further, while the vehicle is stopped, advice on the event generation type at the time of stop is generated.

  However, the vehicle frequently stops when riding on a street or in a traffic jam, and the same advice is generated each time the vehicle stops. In this embodiment, measures are taken for this point. The countermeasure will be described with reference to FIG.

In FIG. 6, the first row represents an example of the running / stopped state of the vehicle. The time added in the first row represents the duration (time) of the traveling section / stopping section of the vehicle.
The second row represents advice generation timing.

  In the present embodiment, when advice is generated when the vehicle is stopped (a, b), advice is not generated even if the advice generation timing comes for 5 seconds after the advice is generated. As a result, the above-described problem (specifically, the same advice is generated every time the vehicle stops) is avoided.

Here, FIG. 7 is an example of a display screen that displays the result of the real-time driving diagnosis.
On the real-time driving diagnosis screen shown in FIG. 7, although details will be described later, at least status information, eco-level, fuel consumption information, accumulated points, and advice are displayed.

  The status information displays the driver's driving level and class of driving technology by color coding. The character display color itself is color-coded according to the level. For example, gold is the best, silver is the next best, and blue is the next best.

  The eco level indicates the degree of economic efficiency of driving. For example, the diagnostic results of diagnostic items such as fuel consumption, eco lamp lighting travel diagnosis, eco SW use travel diagnosis, air conditioner use diagnosis, accelerator off travel diagnosis, etc. are comprehensively evaluated and leveled. Also, the evaluation section (period) can be set to one minute, or a trip period (for example, a period from when the accessory switch is turned on to off), or can be arbitrarily set by the driver.

In the fuel consumption information, the fuel consumption at a predetermined time is displayed.
Accumulated points are the total points currently given to the driver. Here, the points will be described. In the present embodiment, a diagnosis result relating to the driving state is transmitted from the driving diagnosis information providing apparatus 10 to the server 4, and the server 4 calculates and records points to be given to the driver based on the diagnosis result. It has become. In the driving diagnosis information providing apparatus 10, point information can be downloaded from the server 4. The points given to the driver are managed by the server 4 and can be used for various payments in various scenes such as shopping, refueling, and highway tollgate. This is intended to give priority to a driver who performs economical driving and safe driving. Eventually, it promotes economical driving and safe driving, and tries to improve fuel efficiency (reducing emissions) and reduce traffic accidents.

Next, the advice in FIG. 7 is generated in the manner described above.
[Driving tendency diagnosis]
Next, driving tendency diagnosis will be described with reference to FIGS.

  In the driving tendency diagnosis, a diagnosis is made for a trend item that is an item representing a driving tendency, and a scoring item is scored based on the diagnosis result. Multiple trend items are set. Further, each trend item is composed of a plurality of individual diagnosis items. Then, each individual diagnosis item is scored, and the average score of the individual diagnosis items becomes the score result of the trend item.

The tendency item scoring results are displayed on the display screen of the display device 109 in a radar chart format as will be described later with reference to FIG.
FIG. 8 is a time chart showing scoring timing (that is, diagnosis timing) and advice generation timing in driving tendency diagnosis.

In FIG. 8, the first level represents the on / off state of the accessory switch (ACC) of the vehicle.
The second level represents an example of the running / stopped state of the vehicle, and sections (10) to (13) represent the traveling section of the vehicle (section where the vehicle speed is greater than 0 km / h), and the other sections represent the vehicle. Represents a stop section (vehicle speed is 0 km / h).

  The third level represents the scoring timing. In other words, it represents the update timing of the radar chart. As shown in the third row, in the driving tendency diagnosis, at each end of the traveling section, that is, at each of the end points of the traveling sections (10) to (13), the driving tendency from the past to that time is diagnosed and the trend item. Is graded (in other words, the radar chart is updated).

  The fourth row represents advice generation timing. The advice is synchronized with the scoring timing. That is, advice is generated at each of the end points of the travel sections (10) to (13).

  Here, the advice is generated for each of the plurality of individual diagnosis items. Therefore, in the present embodiment, advice to be provided to the driver is selected from a plurality of generated advices according to a predetermined rule. This point will be described with reference to FIGS.

First, in S410, whether or not there has been an instruction for screen selection based on a user input (an instruction for screen selection by the user). If it is determined that there is an instruction for screen selection (S410: YES), the process proceeds to S420.

In S420, the instructed screen is displayed. Then, the process proceeds to S440.
If it is determined in S410 that there is no instruction for screen selection (S410: NO), the process proceeds to S430, and the previously selected screen is displayed. The screen selected last time is, for example, a screen set (selected) in the driving diagnosis information providing device 10 when the driving diagnosis information providing device 10 was turned off last time.

  Next, the process proceeds to S440, where it is determined whether the ranking information has been updated. If it is determined that the ranking information has not been updated (S440: NO), the process proceeds to S490. In addition, when the diagnosis result of the driving state is uploaded from the driving diagnosis information providing apparatus 10 to the server 4, update information related to the ranking is downloaded.

If it is determined in S440 that the ranking information has been updated (S440: YES), the process proceeds to S450, and it is determined whether the status represented by the status information has improved.
If it is determined in S450 that the status has not improved (S450: NO), the process proceeds to S470.

On the other hand, if it is determined in S450 that the status has improved (S450: YES), the process proceeds to S460.
In S460, the diagnosis result in the section leading to the status improvement is displayed on the radar chart and provided to the user. That is, the screen changes to a driving tendency diagnosis screen. For example, when the status information is improved from silver to gold, a diagnosis result (result of driving tendency diagnosis) of a section in which the status information has changed from silver to gold is provided. In addition, advice indicating that the driver is given up is displayed along with the diagnosis result.

  Next, proceeding to S470, the diagnosis result of the target period related to ranking calculation is provided. That is, the screen transits to a real-time driving diagnosis screen. Further, when the ranking is increased, an advice for giving up together with the diagnosis result is displayed, and when the ranking is lowered, an advice for calling attention together with the diagnosis result is displayed.

  Next, the process proceeds to S480, and it is determined whether or not a diagnosis result (result of real-time driving diagnosis) for a target period related to ranking calculation is provided for a predetermined section or a predetermined number of times. Here, the predetermined section is a 1.6 km section, and the predetermined number of times is three (provided once for each stop). That is, in S480, it is determined whether the result of the real-time driving diagnosis is provided for 1.6 km or three times (however, it is counted once when the vehicle is stopped).

On the other hand, if it is determined in S480 that the predetermined section or the predetermined number of times has been provided (S480: YES), the process proceeds to S490, and it is determined which of the real-time driving diagnosis screen and the driving tendency diagnosis screen is selected.

  If it is determined in S490 that the real-time driving diagnosis screen is selected, the process proceeds to S500, the real-time driving diagnosis screen is displayed, and the real-time driving diagnosis result is displayed (provided to the user).

  Next, the process proceeds to S510, where it is determined whether or not the same result has been provided for a predetermined number of times (three times in this example), and if it is determined that the same result has not been provided for a predetermined number of times (S510: NO), it returns to S500 again. On the other hand, if it is determined that the same result has been provided for a predetermined number of times (S510: YES), the process proceeds to S520.

In S520, the screen transits to a driving tendency diagnosis screen, and the driving tendency diagnosis result is displayed (provided to the user).
Next, the process proceeds to S530, where it is determined whether or not there has been an instruction to change the screen based on the user's input (whether or not an instruction to change the screen has been input by the user), and if there is no instruction to change the screen (S530). : NO), it returns to S500 again.

  On the other hand, if it is determined in S530 that there is an instruction to change the screen (S530: YES), the process returns to S410 again. In S410, which proceeds from S530, the screen change instruction is regarded as a screen selection instruction (S410: YES), and then the process proceeds to S420 to display the instructed screen.

If it is determined in S490 that the driving tendency diagnosis screen is selected, the process proceeds to S540, and it is determined whether or not a predetermined time has elapsed since the accessory switch was turned on.
When it is determined in S540 that a predetermined time has elapsed since the accessory switch was turned on (S540: YES), the process proceeds to S550, the operation trend diagnosis screen is displayed, and the result of the driving tendency diagnosis is displayed (provided to the user).

  Next, the process proceeds to S560, where it is determined whether or not there has been an instruction to change the screen based on an input from the user (whether or not an instruction to change the screen has been input by the user), and it is determined that there has been no instruction to change the screen (S560). : NO), the process returns to S550.

On the other hand, if it is determined in S560 that there is an instruction to change the screen (S560: YES), the process returns to S410 again.
If it is determined in S540 that the predetermined time has not elapsed since the accessory switch was turned on (S540: NO), the process proceeds to S570.

In S570, the screen transits to a real-time driving diagnosis screen, and the result of the real-time driving diagnosis is displayed (provided to the user).
Next, the process proceeds to S580, where it is determined whether or not there has been an instruction to change the screen based on the user's input (whether or not an instruction to change the screen has been input by the user), and it is determined that there has been no instruction to change the screen (S580). : NO), the process returns to S540.

On the other hand, if it is determined in S580 that there is an instruction to change the screen (S580: YES), the process returns to S410 again.
As described above, according to the present embodiment, the user can select and display either the real-time driving diagnosis screen or the driving tendency diagnosis screen (S410: YES → S420). . That is, since a desired screen desired by the user is displayed, the usability for the user is improved.

  Moreover, in this embodiment, since advice is displayed in addition to the diagnosis result on the real-time driving diagnosis screen and the driving tendency diagnosis screen, respectively, it is possible to contribute to improvement of the driving skill of the driver. As a result, it can lead to improvement of fuel consumption (reduction of exhaust gas) and reduction of traffic accidents.

  In particular, on the driving tendency diagnosis screen, the user selects a trend item (see FIG. 11: “stable driving”, “acceleration / deceleration”, “in-vehicle environment”, “attention judgment”, “parking”), and the selected tendency. Item advice is generated and provided to the driver. In this case, advice to be provided is selected according to the score of the trend item, and according to this, more appropriate advice can be displayed according to the situation. Furthermore, since the priority of advice is determined and the advice is displayed in the priority order, the desired advice is promptly provided to the driver. According to such a configuration, the driver's driving skill can be further improved.
