  Hereinafter, one embodiment of a driving evaluation device concerning the present invention is described based on a drawing. FIG. 1 is a block diagram showing an embodiment of a navigation device incorporating the driving evaluation device of the present invention.

  As shown in the figure, the navigation apparatus 1 includes a GPS 2 as a position information acquisition means, a vehicle information measurement device 3 as a first collection means, an evaluation means, a second collection means, a display means, and a score calculation means. CPU 4, vehicle information / position information / time information memory 5, evaluation reference storage memory 6, map database 7, driving evaluation result / trajectory data memory 8, touch panel display 9 as a display and operating means, It has.

  The GPS 2 receives a GPS signal from a GPS (Global Positioning System) satellite (not shown). The vehicle information measuring device 3 includes, for example, a speed sensor, an acceleration sensor, and the like, and measures a plurality of types of vehicle information such as a speed, an acceleration, and a deceleration that indicate a running state of the vehicle from these sensors.

  The CPU 4 controls the navigation device 1 as a whole, controls the GPS 2 to receive GPS signals at regular intervals, and measures the position information of the latitude and longitude of the vehicle based on the received GPS signals. Time information is measured based on the GPS signal, and the measured position information and time information are sequentially stored in a vehicle information / position information / time information memory 5 described later.

  The CPU 4 controls the vehicle information measuring device 3 to measure the speed, acceleration, and deceleration at regular time intervals, and the measured speed, acceleration, and deceleration are sequentially described in the vehicle information / position information / Store in the time information memory 5.

  Further, as shown in FIG. 3, the CPU 4 collects speed, acceleration, and deceleration by the vehicle information measuring device 3, a function for displaying a map and a mark M <b> 1 indicating the current position of the vehicle on the touch panel display 9. Each time, the collected speed, acceleration, and deceleration are compared with the preset speed reference value, acceleration reference value, and deceleration reference value (reference value) to evaluate whether the vehicle is safe driving or not. Function, a function for collecting vehicle position information at a point evaluated as not safe driving using GPS2, as shown in FIG. 4, a map, a driving trajectory M2 on the map, and a driving trajectory M2 is not safe driving The touch panel display 9 has a function of displaying the mark M3 indicating the evaluated point.

  The evaluation reference storage memory 6 is a memory in which the above-described speed reference value, acceleration reference value, and deceleration reference value are stored in advance. The map database 7 is a memory in which map information is stored in advance. The driving evaluation result / trajectory data storage memory 8 stores the above-described evaluation result as to whether or not the driving is safe, the trajectory data indicating the driving trajectory of the vehicle, and the position information indicating the point evaluated as not safe driving. It is.

  The touch panel display 9 displays various information, and when the screen is pressed, detects the pressed position and outputs it to the CPU 4.

  Next, the operation of the navigation device 1 configured as described above will be described with reference to FIG. FIG. 2 is a flowchart showing a processing procedure of the CPU 4 constituting the navigation device shown in FIG. When the CPU 4 operates a vehicle information selection button (not shown), the CPU 4 displays a vehicle information selection screen on the touch panel display 9. For example, a plurality of types of vehicle information measured by the vehicle information measuring device 3 are displayed side by side on the vehicle information selection screen, and the user selects vehicle information to be evaluated by touching the touch panel display 9. be able to.

  CPU4 will start a process, if operation of the operation start button which is not shown in figure is performed, First, it controls the vehicle information measuring device 3, and collects vehicle information (step S1). Thereafter, the CPU 4 stores the collected vehicle information in the vehicle information / position information / time information memory 5 (step S2).

  Next, the CPU 4 causes the GPS 2 to receive a GPS signal, measures position information and time information based on the received GPS signal (step S3), and uses the position information and time information as vehicle information / position information / time. The information is stored in the information memory 5 and the operation evaluation result is stored as the operation track in the track data storage memory 8 (step S4).

  Thereafter, the CPU 4 performs driving evaluation (step S5). Here, the CPU 4 performs driving evaluation of only the vehicle information selected on the vehicle information selection screen described above from among a plurality of types of vehicle information collected by the vehicle information measuring device 3. Here, in order to simplify the description, a case will be described in which speed, acceleration, and deceleration are selected from a plurality of types of vehicle information.

  Whether the CPU 4 is in safe driving by comparing the speed, acceleration, and deceleration collected in the immediately preceding step S1 with the speed reference value, acceleration reference value, and deceleration reference value stored in the evaluation reference storage memory 6. Determine whether or not. Specifically, if the acceleration is equal to or higher than the acceleration reference value, the CPU 4 determines that the vehicle is suddenly started and is not safe driving. Further, if the deceleration is equal to or greater than the deceleration reference value, the CPU 4 determines that the vehicle is suddenly decelerating and is not a safe driving. Further, if the speed is equal to or higher than the speed reference value, the CPU 4 determines that the speed is over and that the driving is not safe.

  Next, as a result of the driving evaluation in step S5, when the CPU 4 evaluates that the driving is not safe (N in step S6), the CPU 4 counts up the number of sudden starts, the number of sudden decelerations, or the number of overspeeds, and the driving evaluation result, locus The data is stored in the data storage memory 8 (step S7). Specifically, if the CPU 4 determines that the acceleration is not less than the acceleration reference value and is not safe driving, the CPU 4 counts up the number of sudden starts, and determines that the deceleration is not less than the deceleration reference value and is not safe driving. Then, the number of sudden decelerations is counted up, and if the speed is equal to or higher than the speed reference value, the number of times of overspeed is counted up and stored in the operation evaluation result / trajectory data storage memory 8. That is, here, the number of times of safety failure is counted up for each vehicle information. The sudden start number, sudden deceleration number, and overspeed number are reset to 0 each time an operation is performed and one operation is completed.

  Next, the CPU 4 counts up the continuous number n of failing safe driving (step S8). Thereafter, the CPU 4 deducts the driving evaluation score and stores it in the driving evaluation result / trajectory data storage memory 8 as a new driving evaluation score (step S9).

  The operation evaluation score described above is initially set to 100, for example. If the number of consecutive times n counted up in step S8 is less than the predetermined number N, the CPU 4 deducts one point (first predetermined number) from the driving evaluation score, and the number of consecutive times n counted up in step S8 is equal to or greater than the predetermined number N. If there is, the operation evaluation score is deducted by 5 points (second predetermined score). This operation evaluation score is reset to 100 again every time a service end operation is performed and one service ends.

  Next, the CPU 4 performs driving by associating the vehicle information evaluated as not safe driving, the point evaluated as not safe driving (position information measured in step S3 performed immediately before), and the deduction point of the driving evaluation score. After the evaluation result is stored in the trajectory data storage memory 8 (step S10), the process proceeds to step S11.

  On the other hand, if the CPU 4 is evaluated as safe driving as a result of the driving evaluation in step S5 (Y in step S6), the CPU 4 resets the number of consecutive times n of failing safe driving to 0 (step S15). Immediately proceed to step S11.

  In step S11, the CPU 4 displays, on the right screen of the touch panel display 9, as shown in FIG. 3, the driving evaluation result, the sudden start count stored in the trajectory data storage memory 8, the rapid deceleration count, and the speed Over count. And the driving evaluation score are displayed. Further, the CPU 4 reads the surrounding map of the position information measured in the previous step S3 from the map database 7, and the loaded surrounding map and the vehicle on the surrounding map are displayed on the left screen of the touch panel display 9 as shown in FIG. A mark M1 indicating the current position of the current position is displayed (step S12).

  Next, the CPU 4 determines whether or not the user has pressed the right screen of the touch panel display 9 (step S13). If the right screen is pressed (Y in step S13), the CPU 4 switches the screen of the touch panel display 9 as shown in FIG. 4 for a predetermined time (step S14), and then returns to step S1. That is, the CPU 4 determines the driving evaluation result, the trajectory data stored in the trajectory data storage memory 8, the vehicle information evaluated in the step S <b> 9 that is not associated with safe driving, the point that is evaluated as not safe driving, the driving Read the deduction points of the evaluation points.

  Then, the CPU 4 reads the surrounding map of the operation trajectory from the map database 7, and as shown in FIG. 4, the read surrounding map, the operation trajectory M2 on the surrounding map, and the operation are displayed on the entire screen of the touch panel display 9. A mark M3 indicating a point evaluated as not safe driving is displayed on the trajectory M2.

  At this time, the CPU 4 displays the mark M3 in different colors for each vehicle information that has neglected safety, such as red for a point where the speed is over, blue for a point where the vehicle is suddenly decelerated, and yellow for a point where the vehicle is suddenly accelerated. Let That is, the CPU 4 displays a different mark for each vehicle information, so that the vehicle information neglecting safety can be known at a glance.

  Further, the CPU 4 makes a mark different for each deduction point, such as a star shape for points that have been neglected for 5 consecutive points for a predetermined number of times N, and a round shape for points deducted by 5 points. You can see at a glance the number of points that have been continuously unsafe and the number of points deducted.

  According to the navigation device 1 described above, the CPU 4 collects the position information of the vehicle at the point evaluated not to be safe driving using the GPS 2, and as shown in FIG. 4, the map, the operation locus M2 on the map, and Since the mark M3 indicating the point evaluated as not safe driving on the operation track M2 is displayed on the touch panel display 9, it is possible to grasp at which point the safe driving is neglected.

  Moreover, according to the navigation apparatus 1 mentioned above, since CPU4 evaluates only the vehicle information selected by the touch panel display 9 among multiple types of vehicle information, it can evaluate a user's original safe driving.

  In addition, according to the navigation device 1 described above, a point that is overspeeded is red, a point that is suddenly decelerated is blue, and a point that is suddenly accelerated is yellow. Since the mark M3 is displayed, it is possible to grasp how and where the safe driving is neglected at which point.

  In addition, according to the navigation device 1 described above, the CPU 4 makes a point for every deduction point such as a star for points that have been neglected safety for a predetermined number of times N or more and rounded for points deducted by 5 points. Marks are different. That is, if the CPU 4 evaluates that it is not safe driving continuously for a predetermined number of times N or more, the mark M3 at that point is displayed differently from the other marks M3, so it is possible to grasp how much safe driving has been neglected. be able to.

  Further, according to the navigation device 1 described above, every time the CPU 4 determines that the driving is not safe, the driving evaluation score is deducted and the driving evaluation score is displayed on the touch panel display 9. It is possible to grasp the safe driving degree.

  Further, according to the navigation device 1 described above, if the CPU 4 evaluates that the vehicle is not safe driving a predetermined number of times N or more, the driving evaluation score is deducted by 5 points larger than the normal 1 point, so that the user However, the degree of safe driving can be grasped by the score.
