<< First Embodiment >>
As shown in FIG. 1, the driving content evaluation apparatus 1 according to the first embodiment of the present invention stores operation data and the like recorded by a drive recorder 30 mounted on a vehicle (not shown) on a memory card 50 (SDHC ( (Secure Digital High-Capacity) card, etc.), and is a device that evaluates the driving content of the driver based on the read operation data.

[Configuration Example of Drive Recorder 30]
First, a configuration example of the drive recorder 30 will be described. In the following description, the host vehicle is a vehicle on which the drive recorder 30 that explains the configuration and functions is mounted.

  FIG. 2 shows a configuration example of the drive recorder 30. As shown in FIG. 2, the drive recorder 30 includes a reader / writer 31, a clock circuit 32, an acceleration sensor 33, a GPS receiver 34, a communication circuit 35, a control unit 36, an image processing circuit 37, and a RAM (Random Access Memory). 38 and a non-volatile memory 39. The drive recorder 30 is connected with a camera 42, a microphone 43, a recording switch 44, an operation unit 45, and the like.

  The recording switch 44 is a switch that receives a recording instruction to the memory card 50. By pressing the recording switch 44, the user can record the moving image data on the memory card 50 at a desired timing, such as when the user feels a danger although no accident such as a collision has occurred.

  The operation unit 45 includes a plurality of buttons, and receives input such as various settings from the user. User operation contents received by the recording switch 44 and the operation unit 45 are input to the control unit 36 as signals.

  The camera 42 includes a lens and an image sensor, and can acquire image information electronically. In the present embodiment, the camera 42 can acquire image information about a region in front of the vehicle near the top of the windshield in a state where its optical axis is directed to the front of the vehicle (for example, between the room mirror and the windshield). ). As shown in the figure, data from the recording switch 44 and the operation unit 45 are input to the control unit 36, and an image signal from the camera 42 is input to the image processing circuit 37.

  The timer circuit 32 generates a signal corresponding to the current time and outputs the signal to the control unit 36. The clock circuit 32 has an internal battery, for example, so that it operates and clocks accurate time without receiving power supply from the outside.

The acceleration sensor 33 detects the acceleration indicating the magnitude of the impact applied to the host vehicle with the gravitational acceleration G as a unit. The detected acceleration is an instantaneous value of acceleration at the current time, and has a magnitude in a direction corresponding to, for example, three axes orthogonal to each other or two axes. The acceleration sensor 33 outputs a signal corresponding to such acceleration to the control unit 36.

  The GPS receiver 34 is a unit that detects the position of the host vehicle at the current time based on a signal from a GPS satellite and outputs the detected position data to the control unit 36. The detected position data is, for example, position information expressed by latitude and longitude on the earth. The communication circuit 35 is a circuit for performing communication between the drive recorder 30 and another device (navigation device or the like). Since the GPS receiver 34 can detect an accurate time based on a signal from a GPS satellite, it can be used with the clock circuit 32 or used to correct the time of the clock circuit 32. .

  The microphone 43 is a device that converts sound generated around the host vehicle into an electric signal. The output of the microphone 43 is input (stored) in the RAM 38 via a signal processing circuit (not shown).

  The control unit 36 is a unit (unit centering on the CPU) that executes various processes according to a program stored in the nonvolatile memory 39. The nonvolatile memory 39 is composed of, for example, a hard disk or a flash memory, and stores programs as firmware, setting parameters, and the like. The function of controlling each unit of the drive recorder 30 is realized by the control unit 36 executing arithmetic processing according to a program stored in advance in the nonvolatile memory 39. As shown in the figure, data from the vehicle speed sensor and data from the IG sensor for detecting the state of the ignition key (ON / OFF) are input to the control unit 36.

The image processing circuit 37 performs A / D (analog-to-digital) conversion, luminance correction, contrast correction, and the like on the image signal input from the camera 42 to thereby obtain a predetermined format (for example,
JPEG format) digital image data, and the generated image data is stored in the RAM 38. A signal processing circuit (not shown) provided between the microphone 43 and the RAM 38 is a circuit that converts a signal from the microphone 43 into digital data (hereinafter referred to as sound data) and stores it in the RAM 38.

  A part of the storage area of the RAM 38 (hereinafter referred to as a ring buffer area) is used as a ring buffer. Using this ring buffer area, image data for the past certain time processed in the image processing circuit 37 and sound data for the past certain time processed in the signal processing circuit are always stored. At this time, driving data acquired by the clock circuit 32, the acceleration sensor 33, the GPS receiver 34, the vehicle speed sensor, and the like are also always stored. The control unit 36 stores the operation data, the image data, and the sound data in the RAM 38 in association with each other. That is, the control unit 36 associates the image data processed in the image processing circuit 37 and the sound data processed in the signal processing circuit with the operation data at the time when each data was acquired by the camera 42 or the microphone 43, Store in the ring buffer area of the RAM 38.

  The driving data is data indicating the driving state of the vehicle including acceleration data acquired by the acceleration sensor 33, vehicle speed data acquired by the vehicle speed sensor, and the like.

  The size of the ring buffer area is determined so that, for example, image data and sound data for about 40 seconds can be stored.

The reader / writer 31 has a card slot for inserting a memory card 50. Under the control of the control unit 36, the reader / writer 31 reads data from the memory card 50 inserted in the card slot and reads data from the memory card 50. This unit performs writing. When a predetermined event such as an accident or dangerous behavior occurs, the control unit 36 generates moving image data from the image data and sound data stored in the ring buffer area of the RAM 38. In addition, the control unit 36 uses the operation data stored in the ring buffer area of the RAM 38 to generate operation content information indicating the type of event that has occurred. Then, the control unit 36 controls the reader / writer 31 so that the generated moving image data, the operation content information, and a part of the operation data on the ring buffer area are stored in the card card of the reader / writer 31. Record 50.

[Operation Example of Drive Recorder 30]
FIG. 3 shows an operation example in which the drive recorder 30 according to the present embodiment records operation content information and the like on the memory card 50. This operation example is executed based on a program recorded in the nonvolatile memory 39. Further, it is assumed that the memory card 50 is attached to the reader / writer 31 at the start of this operation example. Further, this operation example is executed under the control of the control unit 36 unless otherwise specified.

  The drive recorder 30 is activated, for example, by turning on an ignition switch of the vehicle. The drive recorder 30 executes a predetermined initial process when starting.

  Immediately after the initial processing is completed, the drive recorder 30 acquires image data indicating the surroundings of the vehicle by the camera 42, acquisition of sound data indicating sounds generated around the vehicle by the microphone 43, and time measurement. Acquisition of driving data by the circuit 32, the acceleration sensor 33, the GPS receiver 34, the vehicle speed sensor, and the like is started. The acquired image data, sound data, and driving data are stored in the ring buffer area of the RAM 38 (step 101). Thereafter, the image data, the sound data, and the operation data are continuously stored in the RAM 38 during the operation of the drive recorder 30. For example, the image data is continuously stored in the RAM 38 at a rate of 30 times per second. At this time, the image data is stored at a frame rate of 30 fps (30 frames per second). Note that the image data and sound data acquired at the same time and the operation data are associated with each other.

  In this way, while image data, sound data, and driving data are continuously stored, whether or not an event for stopping the operation of the drive recorder 30 has occurred, for example, by turning off the ignition switch of the vehicle. Are monitored (step 102). For example, when the ignition switch of the vehicle is turned off (YES in step 102), the drive recorder 30 stops its operation.

  On the other hand, if an event for stopping the operation of the drive recorder 30 has not occurred (NO in step 102), it is monitored whether or not a predetermined event has occurred (step 103).

  In step 103, it is monitored whether or not an event that satisfies the following conditions (A) to (C) is generated.

(A) The acceleration sensor 33 continuously detected acceleration of a predetermined value or more for a predetermined time or more. For example, the acceleration sensor 33 continuously detects an acceleration of 0.40 G or more for 100 milliseconds or more.
(B) While the vehicle is traveling at a predetermined speed or more, the vehicle speed sensor detects a predetermined deceleration or more within a predetermined period. For example, while the vehicle is traveling at a speed of 60 km / h or more, the speed difference per second detected by the vehicle speed sensor is 14 km / h or more.
(C) The recording switch 44 is pressed by the user.

  In addition, the predetermined value and threshold value in each condition may be set and changed by the user.

Condition (A) is a condition relating to a situation in which relatively strong acceleration occurs and the probability of occurrence of a vehicle collision accident is high. An event that satisfies the condition (A) is called “G detection”.
The condition (B) is a condition related to a situation in which a relatively rapid deceleration has occurred in the vehicle and there is a high probability that an accident has imminently occurred. An event that satisfies this condition (B) is called “rapid deceleration”.
The condition (C) is a condition related to a situation where a user (typically a vehicle driver) desires to record moving image data. An event that satisfies this condition (C) is called a “switch operation”.

  When a certain event occurs (YES in step 103), for example, when G detection, sudden deceleration, etc. occur, image data for a total of 20 seconds, 12 seconds before the event and 8 seconds after the event occurs Sound data and driving data are read from the ring buffer area of the RAM 38. For example, when a switch operation occurs, image data, sound data, and operation data for an arbitrary time are read out from the ring buffer area of the RAM 38 after the occurrence of the event. At this time, if necessary, image data and operation data may be read from an area other than the ring buffer area. The arbitrary time may be a time set in advance as a set value stored in the nonvolatile memory 39, or may be set through the memory card 50 by specifying the time in the information processing apparatus. Good.

  Then, moving image data is generated from the read image data and sound data. This moving image data shows the situation around the vehicle when the event occurs. The generated moving image data and operation data read from the ring buffer area of the RAM 38 are recorded in the memory card 50 (step 104). Also, information indicating the type of event that occurred (G detection, sudden deceleration, etc.), information indicating the date and time of the event, and vehicle position data at the time of the event (detected by the GPS receiver 34 when the event occurred) The operation content information including the position data is also recorded in the memory card 50 (step 104).

  Note that the event monitoring process for stopping the operation of the drive recorder 30 according to step 102 may not be executed. At this time, for example, when the user turns off the ignition switch, a process for forcibly stopping the operation of the drive recorder 30 is generated and executed, whereby the operation of the drive recorder 30 is stopped.

  FIG. 4 illustrates a state of the memory card 50 in which information is recorded by the operation of the drive recorder 30 as described above.

The vehicle number (“000002”) shown in FIG. 4 is identification information of the own vehicle (a vehicle in which the drive recorder 30 having information recorded on the memory card 50 is mounted), and the vehicle type information (“002”).
) Is information indicating the model of the host vehicle. These pieces of information are information written in the non-volatile memory 39 in the drive recorder 30 at the time of setting up the drive recorder 30. When the memory card 50 is set in the drive recorder 30, information recorded thereafter is the drive recorder. 30 is recorded in the memory card 50 as information indicating that the recorded information is recorded at 30.

  Further, “2011/01/25 09:11:23 rapid acceleration P1x, P1y” and the like in FIG. 4 are operation content information recorded in the memory card 50 by the drive recorder 30.

For example, the exclusion item information associated with the vehicle type information 001 excludes each of the violation driving items of overspeed, rapid acceleration, and sudden deceleration from the evaluation target ( It is not used for evaluation of driving details). The control part 12 can specify the violation driving item excluded from evaluation object (henceforth an exclusion violation driving item) to a vehicle classification by reading such an exclusion item information group from the memory | storage part 11. FIG.

  Note that the excluded item information regarding a certain vehicle type only needs to be information indicating a violation driving item that is not used for evaluation of driving contents of the vehicle of the vehicle type. Therefore, information including only the name (identification information) of each violating driving item that is not used in the evaluation of driving content can be adopted as the excluded item information regarding each vehicle type.

  The storage unit 11 (FIG. 5) is realized by, for example, a hard disk or a flash memory. The storage unit 11 may be realized by a removable recording medium such as a USB (Universal Serial Bus) memory or an SD card memory.

The control part 12 performs the calculation about various data and control of each structure by running the program stored in the memory | storage part 11, and implement | achieves the process of the driving | running content evaluation apparatus 1 in this embodiment.

As shown in FIG. 5, the control unit 12 displays the operation content information regarding each driver based on the operation data collected by the drive recorder 30 of the vehicle driven by each driver as the driving history D.
It functions as the database update unit 121 to be added to B110, and operates to change the type of driving content information to be added to the driving history DB 110 based on the vehicle type of each vehicle. Moreover, the control part 12 functions also as the evaluation part 122 which evaluates the content of driving | operation with respect to a vehicle of each driver | operator based on the information in driving history DB110.

  The input / output unit 14 is one or a plurality of interfaces for exchanging various data with a device existing outside the operation content evaluation device 1. The input / output unit 14 is, for example, an interface for connecting a LAN (Local Area Network) cable, an interface for connecting to a user interface, or an interface such as a USB.

  The input / output unit 14 is connected to the operation device 5 such as a touch panel, a numeric keypad, a keyboard, and a mouse. The input / output unit 14 is connected to the display 6. When the operation device 5 is a touch panel, the operation device 5 and the display 6 may be configured as an integrated device.

  The card slot 15 is configured so that the memory card 50 can be attached and detached, and reads data from the inserted memory card 50 and writes data to the memory card 50. The operation content evaluation apparatus 1 acquires operation data and the like from the memory card 50 through the card slot 15. In addition, the acquisition method of the operation data etc. by the driving | operation content evaluation apparatus 1 can also take the method of acquiring the operation data etc. which were recorded by the drive recorder 30 by communication, such as the internet, for example.

Further, the driving content evaluation device 1 may be a general-purpose computer such as a PC (Personal Computer) or an in-vehicle device such as a navigation device.

[Operation example of the operation content evaluation apparatus 1]
Hereinafter, an operation example of the control unit 12 included in the driving content evaluation apparatus 1 will be described.

  The control unit 12 that has started the operation in accordance with the program on the storage unit 11 monitors input of various instructions. The instructions for monitoring the input of the control unit 12 include an exclusion violation item confirmation / change instruction, a DB update instruction, a ranking screen display instruction, a violation item list screen display instruction, and the like.

  When detecting that an exclusion violation item confirmation / change instruction has been input, the control unit 12 first reads the exclusion item information (see FIG. 6) for each vehicle type from the storage unit 11.

  Next, the control unit 12 displays an exclusion violation item setting screen showing the setting status of the exclusion violation driving item (violating driving item not used for evaluation of driving content) for each vehicle type based on the read exclusion item information. 6 is displayed. The exclusion violation item setting screen is provided with various items (such as check boxes) for receiving an instruction to change the content of the exclusion item information for each vehicle type.

  The control unit 12 displaying the exclusion violation item setting screen on the display 6 allows the user (operator of the driving content evaluation apparatus 1) to perform exclusion item information on a certain vehicle type by operating the item on the exclusion violation item setting screen. When the change is instructed, the exclusion item information for the vehicle type in the storage unit 11 is changed to the information of the content instructed by the user.

  The control unit 12 deletes the exclusion violation item setting screen from the display 6 when the user inputs a deletion instruction of the exclusion violation item setting screen by operating the operation device 5. And the control part will be in the state which is monitoring the input of various instructions.

  When detecting that a DB update instruction is input, the control unit 12 executes a database update process for registering the data stored in the memory card 50 acquired by the drive recorder 30 in the operation history DB 110.

  FIG. 7 shows a processing procedure example of the database update processing. This database update process is executed when the control unit 12 detects a DB update instruction. First, the control unit 12 reads various information (vehicle type information, operation data, moving image data, etc.) from the memory card 50 set in the card slot 15 (step 201). Next, the control unit 12, based on the vehicle type information read from the memory card 50 and the excluded item information stored in the storage unit 11, excludes violation regarding the vehicle to be evaluated (the vehicle from which the vehicle number and the like are read from the memory card 50). An operation item is specified (step 202). More specifically, the control unit 12 reads out and reads out information related to the illegal driving item corresponding to the vehicle type information read out from the memory card 50 from the excluded item information (see FIG. 6) read out from the storage unit 11. Among the violating driving items, the violating driving items indicating information ("exclusion") indicating that they are not used for the evaluation of driving contents are specified as the excluded violating driving items regarding the evaluation target vehicle.

  Thereafter, the control unit 12 obtains information obtained by removing information (driving content information, moving image data, and operation data) related to each specified exclusion violation driving item from the information read from the memory card 50, and information related to the driving content of the evaluation target vehicle. Is registered in the operation history DB 110 (step 203). And the control part 12 will be in the state which complete | finishes this database update process and monitors the input of various instructions.

  Note that the controller 12 may be programmed so that this database update process starts automatically when the memory card 50 is inserted into the card slot 15 instead of when a DB update instruction is input. I can do it.

  The control unit 12 displays a ranking screen on the display 6 when a ranking screen display instruction is input.

  FIG. 8 shows an example of the ranking screen. Items in this ranking screen area 41 are search conditions for narrowing down the driver (crew) who evaluates the driving content by the department to which the driver belongs. By inputting the department name in the input field arranged in the area 41, only the data relating to the driver belonging to the input department is extracted. Each item in the region 42 is a search condition for designating a period during which the driving content is evaluated. Data extraction conditions can be specified by specifying (checking) one of the check boxes arranged in the area 42, and any date can be specified by entering the date in the date input field. be able to. Each item in the region 43 is an output condition for designating the number of data and the order in which it is output as the evaluation result of the operation content. By specifying (checking) a check box indicating a ranking condition arranged in the area 43, it is possible to specify an output form. Then, the data is narrowed down to the data included in the range of values input in the ranking condition and score condition input fields, and output in the ranking format.

  In the area 44, a check box that can specify an illegal driving item to be excluded from the evaluation target is arranged, and an evaluation condition of driving content can be specified. By designating (checking) one or more of these check boxes, the operation details are evaluated by excluding the designated violating operation items.

The “search” button on the ranking screen is a button for causing the control unit 12 to start the evaluation result output process. When the “search” button is pressed, the control unit 12 executes a search based on the search condition, the output condition, and the evaluation condition specified in the areas 41 to 44, and the area 45
The search result is output to.

  FIG. 9 shows a processing procedure example of the evaluation result output process. This evaluation result output process is executed when the control unit 12 detects the pressing of the “search” button. First, the control part 12 reads each driving | operation content information regarding each driver (crew, vehicle) which satisfy | fills the conditions specified with the item in the area | region 41 from driving history DB110 (step 301).

  More specifically, the control unit 12 narrows down the data related to the driver belonging to the department input in the input field arranged in the area 41, and the check box arranged in the area 44 is checked. Only the operation content information (not specified to be used for the evaluation by the flag information) for the non-violating operation is read from the operation history DB 110. The flag information is information set by the user using the violation item list screen (FIG. 10). Therefore, details of the flag information will be described later together with the operation of the control unit 12 related to the violation item list screen.

  And the control part 12 calculates | requires the evaluation score (overall evaluation), rank, order | rank, etc. of the read driving | operation content information for every crew member (step 302).

  Then, the control unit 12 outputs to the area 45 in the ranking format for each crew member based on the output condition specified in the area 43 and the obtained evaluation score (overall evaluation), rank, rank, etc. (step 303).

  Then, the control unit 12 terminates the evaluation result output process and monitors whether various conditions are reset, the “ranking print” button is pressed, a ranking screen deletion instruction is input, and the like. It will be in the state.

  When detecting the violation item list screen display instruction, the control unit 12 displays the violation item list screen on the display 6.

  FIG. 10 shows an example of the violation item list screen. If there is no designation from the user, the violation item list screen displayed on the display 6 immediately after the input of the violation item list screen display instruction by the control unit 12 is a screen in which nothing is shown in the area 46 or the area 47. It is.

  Thereafter, the control unit 12 monitors the operation of each item on the violation item list screen, changes the display form of the operated item (check box, radio button), and inputs information (or A state in which the information is displayed in the selected item (text box) is entered.

  When the control unit 12 detects that the “search” button has been pressed, the control unit 12 includes the crew member belonging to the department input in the department input field and the crew name input in the crew name input field. The crew data is narrowed down, and the driving content information corresponding to the data included in the range of the period input in the input column for the target date is searched from the driving history DB. Next, the control unit 12 displays a list with a check box of information indicating the content of the searched operation content information in the area 46 of the violation item list screen.

  In addition, when information related to a certain illegal driving is selected from the list displayed in the area 46 by the processing as described above, the control unit 12 displays a map centered on the place where the illegal driving is performed. 47.

Further, the control unit 12 checks the check box when the “Confirm change” button is pressed in a state where check boxes related to information on some of the offenses on the violation item list screen are checked. Flag information indicating that the information is not used for evaluation of driving content is added to the driving content information in the driving history DB 110 regarding each violating driving item.

  As already described, the evaluation result output process executed by the control unit 12 relates to a violation driving in which the check box in the region 44 is not checked for each driver that satisfies the specified condition in step 301. This is a process of reading only the operation content information (not specified to be used for evaluation by the flag information) from the operation history DB 110.

  Therefore, when flag information is added to certain driving content information related to a certain driver by an operation on the violation item list screen, the driving content information with the flag information added is displayed on the ranking screen (FIG. 8). An evaluation result (such as “overall evaluation”) regarding the excluded driver is displayed.

  As described above, the operation content evaluation apparatus 1 according to the first embodiment of the present invention selects the type of operation content information to be recorded in the operation history DB 110 for storing original data for operation content evaluation. It has a function of changing according to the vehicle type of the information recording target vehicle. And, since it was decided not to register in the driving history DB 110 for each vehicle type a violation driving item that is not subject to driving content evaluation (excluded from the driving content evaluation target) for a specific vehicle type, However, it is possible to evaluate the proper operation content with the same evaluation criteria. As a result, it is possible to make the driver objectively recognize his / her driving content and to further raise awareness and promote safe driving and economical driving (eco-driving).

<< Second Embodiment >>
The driving content evaluation device 1 according to the second embodiment of the present invention is a device that is different from the driving content evaluation device 1 described above only in the contents of the database update process and the evaluation result output process executed by the control unit 12. Therefore, in the following, the same reference numerals are used for the same configurations and the like as in the first embodiment, and the same description is omitted, and the database update mainly executed by the control unit 12 of the driving content evaluation device 1 according to the second embodiment. The contents of the process and the evaluation result output process will be described.

  The outline of the features of the operation content evaluation device 1 according to the second embodiment is not taken into the database except for the information on the exclusion violation operation item from the memory card 50, and the operation data including the information on the exclusion violation operation item. This is the point that the data on the exclusion violation operation item is excluded when the operation data is extracted from the database for evaluation or analysis, or when it is extracted and processed. This is the main difference from the operation content evaluation apparatus 1 according to one embodiment. Hereinafter, the configuration will be described.

  First, the control part 12 (database update part 121) of the drive content evaluation apparatus 1 which concerns on 2nd Embodiment carries out evaluation object vehicle about all the drive content information in the operation data read from the memory card 50 as a database update process. It is configured (programmed) so as to execute processing to be recorded in the driving history database 110 as information on the driver. For data already recorded in the operation history database 110, the same data is deleted so as not to be recorded twice.

  FIG. 11 is a flowchart illustrating an example of a processing procedure of an evaluation result output process executed by the control unit 12. This evaluation result output process is executed when it is detected that the “Search” button on the ranking screen (FIG. 8) has been pressed.

As shown in FIG. 11, the control unit 12 that has started the evaluation result output process firstly
Each driving content information regarding each driver (crew, vehicle) that satisfies the conditions specified by the items in the area 41 is read from the driving history DB 110 (step 401).

  Similarly to the process of step 301, the process of step 401 also includes data corresponding to the specified exclusion violation driving item (violating driving item in which the check box in the region 44 of the ranking screen (FIG. 10) is checked) This is a process in which data in a period outside the period designated for import is not read.

  Next, the control unit 12 reads out exclusion item information for each vehicle type from the storage unit 11 to identify an exclusion violation operation item for each vehicle type (step 402).

  Thereafter, the control unit 12 excludes, for each vehicle, data corresponding to the specified exclusion violation driving item from the data read in step 401, and the remaining data, that is, a non-exclusion violation that is not an exclusion violation driving item. Using only the driving content information related to the driving item, the evaluation point, rank, rank, etc. of the driver (crew) of the vehicle are obtained (step 403).

  Next, the control unit 12 displays the obtained evaluation score in a list in the area 45 in a form designated by various items in the area 42 together with other information on each driver (step 404). And the control part 12 complete | finishes this evaluation result output process.

  As is clear from the above description, the driving content evaluation apparatus 1 according to the second embodiment of the present invention records all types of driving content information in the driving history database 110, and at the time of evaluating the driving content of each driver, It becomes operation | movement which changes the item used for evaluation according to the vehicle model of a vehicle.

  Therefore, even with this driving content evaluation apparatus 1, the driving content information indicating that the driver of the mixer truck has violated the idling stop is taken into consideration and the driving content of the driver is not evaluated low. It is possible to evaluate each driver's driving contents in the form (that is, in a form that can obtain a more appropriate evaluation result). In addition, since all types of driving content information are recorded in the driving history database 110, it is possible to perform an evaluation in which the evaluation target item is changed according to the vehicle type, an evaluation in which the evaluation target item is weighted according to the vehicle type, or the like. .

<< Third Embodiment >>
Next, a third embodiment according to the present invention will be described.

  The feature (difference between the first and second embodiments) of the driving content evaluation apparatus 1 according to the third embodiment of the present invention is that only data used for evaluation (driving content information regarding non-excluded dangerous driving items) is used in the drive recorder. The point is to record in the memory card 50. The hardware configuration and the like are the same as those in the first and second embodiments. Mainly, the configuration of the drive recorder is different from the processing to be executed (stored execution program). Is omitted.

  First, the drive recorder according to the present embodiment records the excluded item information (information defining each illegal driving item that is not used for evaluation of driving content) in the nonvolatile memory 39 according to the vehicle type of the vehicle. The exclusion item information is set and registered when the drive recorder is mounted on a vehicle or the like.

  FIG. 12 is a process executed by the control unit 36 of the drive recorder, and is repeatedly executed during the drive recorder operation.

That is, the control unit 36 that has started this process first monitors the occurrence of various events based on the output of the acceleration sensor 33 and the vehicle speed sensor (step 501). And the control part 3
If the occurrence of the event is not detected (step 501; NO), the process is finished.

  In addition, when the occurrence of a certain event is detected (step 501; YES), the control unit 36 specifies that the detected event is not used for evaluation in the excluded item information on the nonvolatile memory 29. It is determined whether or not the event relates to a dangerous driving item that has been performed (hereinafter referred to as a non-recorded event) (step 502).

  Then, when the event whose occurrence is detected is a non-recorded event (step 502; YES), the control unit 36 ends the process.

  On the other hand, if the event whose occurrence has been detected is not a non-recorded event (step 502; NO), the control unit 36 operates data within a predetermined period including the time when the event occurred on the RAM 28, within the predetermined period. The moving image data file generated from the image data and sound data photographed / recorded is recorded in the memory card 50 (step 503). Moreover, the control part 36 performs the process (step 504) which records driving | running | working content information on the memory card 50, and complete | finishes this process.

  Since the image data and sound data that have been photographed / recorded have the aspect of accident recording, event conditions, recording conditions, and the like may be set separately to perform recording control independent of operation data recording.

  In addition, a function for editing exclusion item information to be recorded on the memory card 50, a function for setting a recording condition for the drive recorder to record operation content information on the memory card 50 for one or more violating operation items, By providing in the operation content evaluation apparatus, it is possible to change the operation items to be recorded, and it is possible to perform evaluation under conditions desired by the user. In this case, an operation unit for specifying exclusion item information and recording conditions, a display unit for displaying the recording contents of the memory card 50, etc. are provided in the drive recorder or the operation content evaluation apparatus, and the specified exclusion item information and recording are provided. This is realized by recording a program for recording the operation content information in a predetermined format on the memory card 50 in accordance with conditions and a program for display and operation in a drive recorder or a recording unit (program storage memory) of the operation content evaluation device.
