Description

  The present invention relates to a vehicle driving evaluation apparatus that evaluates a driving operation by a driver and notifies an evaluation result to the driver.

  There have been many prior arts related to a lane departure prevention device that detects that a vehicle tends to deviate from a travel lane and controls the steering device so as to return to the center of the travel lane (see, for example, Patent Document 1). In the conventional lane departure prevention device according to the related art, it is possible to correct the vehicle position with respect to the driving lane regardless of the characteristics of each driver, and to reduce the physical and mental burden on the driver's vehicle operation. In addition, the safety of vehicle travel can be improved.

JP2011-255817A

  However, even when the lane departure prevention device as described above is used, the lateral displacement (hereinafter referred to as bias) on the traveling lane of the vehicle is not completely eliminated. In addition, by correcting the left-right bias generated in the vehicle with a lane departure prevention device or the like, the vehicle repeats meandering left and right on the travel lane. In order to remove such instability in running of the vehicle, it was necessary to eliminate the root cause of the vehicle being biased in the left-right direction.

By the way, it is conceivable that the factors in which the vehicle is biased in either the left or right direction in the travel lane are due to the vehicle and to the driver's driving habit. As a factor of the vehicle, in general, a vehicle having a short wheelbase is inferior in straight running stability, and it is necessary for the driver to frequently operate the steering wheel to maintain the traveling position of the vehicle. Therefore, in a vehicle having such characteristics, it is difficult to always maintain the center of the traveling lane in the left-right direction without using the lane departure prevention device as described above.
On the other hand, when the factor that the vehicle is biased to the left and right on the travel lane is due to the driver's habit, it goes without saying that there is room for improvement by making the driver recognize the habit of driving operation. However, when the above-described lane departure prevention device or the like is used, the driving position of the vehicle is automatically corrected regardless of the driver's steering operation. Therefore, the driver recognizes his / her habit about the driving position of the vehicle. That was difficult.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle driving evaluation apparatus in which a driver can recognize his own driving habit.

  In order to solve the above-mentioned problem, the invention of the vehicle driving evaluation apparatus (1) according to claim 1 is a vehicle position detection means (4, 4) for detecting a lateral position of the vehicle (13) with respect to the travel lane (DP). 6b), driving evaluation means (6d) for evaluating the driving operation by the driver of the vehicle to form driving evaluation information based on the left-right direction position of the vehicle with respect to the travel lane detected by the vehicle position detecting means, and driving evaluation Evaluation notifying means (11, 12) for notifying the driver of driving evaluation information formed by the means.

  According to this configuration, the driving evaluation unit that evaluates the driving operation by the driver of the vehicle and forms the driving evaluation information based on the lateral position of the vehicle with respect to the travel lane detected by the vehicle position detecting unit, and the driving evaluation unit By providing the evaluation notification means for notifying the driver of the driving evaluation information formed by the driver, the driver can recognize his / her own bag about the traveling position of the vehicle on the traveling lane. For this reason, when the driver consciously corrects his / her own wrinkles, the root cause of the vehicle being biased in the left-right direction on the travel lane can be eliminated, and the safety of vehicle travel can be improved.

<Embodiment 1>
Based on FIG. 1 thru | or FIG. 6, the driving | operation evaluation apparatus 1 for vehicles by Embodiment 1 of this invention is demonstrated. In the following description, it is assumed that the vehicle 13 is on the left side.
As shown in FIG. 1, the vehicle driving evaluation apparatus 1 according to the present embodiment includes a steering angle sensor 2. The steering angle sensor 2 is formed using, for example, a Hall element, and detects the steering angle of the steering wheel 9 of the vehicle 13.
In addition, the vehicle driving evaluation device 1 includes a vehicle speed sensor 3. The vehicle speed sensor 3 detects the speed of the vehicle 13 from the rotational speed of the output shaft of a transmission (not shown).

The vehicle driving evaluation apparatus 1 includes an in-vehicle camera 4 (corresponding to a vehicle position detection unit and a camera device). As shown in FIG. 2, the in-vehicle camera 4 is mounted in the passenger compartment 13 a and is directed to the front of the vehicle 13 so as to photograph the outside of the vehicle. The in-vehicle camera 4 captures a travel lane DP in which the vehicle 13 is traveling and detects the form of the travel lane DP. Further, the in-vehicle camera 4 captures an obstacle such as a utility pole, a pedestrian WP, a bicycle, etc. and an oncoming vehicle 14 that cross each other, and detects the presence of the obstacle and the oncoming vehicle 14. The in-vehicle camera 4 is formed by a CCD camera, but is not limited to this, and may be a CMOS camera, a MOS camera, an infrared camera, or the like. Moreover, the vehicle-mounted camera 4 is not restricted to what is permanently installed in the vehicle 13, and may be of a type brought in from outside the vehicle.
Returning to FIG. 1, the vehicle driving evaluation apparatus 1 includes an ignition switch 5. The ignition switch 5 is provided in the vehicle 13 and is a device for operating an engine ignition device (not shown).

  The steering angle sensor 2, the vehicle speed sensor 3, the in-vehicle camera 4, and the ignition switch 5 described above are connected to the travel position controller 6. The travel position controller 6 is a control device formed by an input / output device (not shown), a CPU, a RAM, and the like. The traveling position controller 6 may be used also as, for example, a steering controller. The travel position controller 6 will be described later.

A steering device 8 is connected to the travel position controller 6 via a steering driver 7. The steering device 8 is a device that steers (steers) the steered wheels 9 regardless of the driver's steering operation. The steering driver 7 controls the operation amount of the steering device 8.
The travel position controller 6 is connected to a display 11 (corresponding to evaluation notification means and display device) and a speaker device 12 (corresponding to evaluation notification means) via an audio ECU 10. The display 11 provided in the passenger compartment 13a is controlled by the audio ECU 10 to display a television image or the like. Further, as will be described later, an evaluation notification image SC (described later) is displayed on the display 11 by notification image data from the travel position controller 6. The display 11 may be formed on a meter (not shown) provided on the instrument panel of the vehicle 13. The display 11 may be a display device of a type that the driver brings from outside the vehicle, such as a display of a mobile phone.
On the other hand, the speaker device 12 is operated and controlled by the audio ECU 10 and generates sound in the passenger compartment 13a. The speaker device 12 generates an evaluation notification message based on the notification voice data from the travel position controller 6.

The travel position controller 6 includes an image processing unit 6a, a vehicle position detection unit 6b, a steering amount calculation unit 6c, a driving operation evaluation unit 6d, and an image audio formation unit 6e.
The image processing unit 6a performs image processing on the detection value obtained by the in-vehicle camera 4 to form running image data.
The vehicle position detection unit 6b (corresponding to the vehicle position detection means) detects the horizontal position of the vehicle 13 on the travel lane DP by a known method based on the travel image data formed by the image processing unit 6a. Form vehicle position data. Specifically, the position of the vehicle 13 can be detected by a method described in Japanese Patent Application Laid-Open No. 2011-255817, which is an open patent publication in which the above-described prior art is described. That is, the vehicle position detection unit 6b, based on the driving image data by the image processing unit 6a, changes the right and left white lines WR and the left white line WL (shown in FIG. The white lines WR and WL are comprehensively recognized (described in JP-A-11-147481). Next, a lane center line CL, which is the center line of the traveling lane DP, is formed by drawing a straight line or a curve at equal positions from both recognized white lines WR and WL. Since the in-vehicle camera 4 is attached to the vehicle 13, the center in the left-right direction of the vehicle 13 is recognized in advance in the travel image data. Therefore, by comparing the lane center line CL with the center of the vehicle 13 in the left-right direction, the position of the vehicle 13 in the left-right direction on the travel lane DP can be estimated. The vehicle position detection unit 6b determines the amount of positional deviation from the lane center line CL of the vehicle 13 (hereinafter, the positional deviation is referred to as deviation, and the positional deviation is referred to as deviation amount) depending on the detected position of the vehicle 13 in the left-right direction. calculate.

  As shown in FIG. 3, the vehicle position detector 6b divides the travel lane DP into five regions according to the position in the left-right direction. A central region NS is set at the center in the left-right direction on the travel lane DP including the lane center line CL. Further, a right end region R1 is set at the right end portion on the travel lane DP. A left end region L1 is set at the left end portion on the travel lane DP. Further, a right connection region R2 and a left connection region L2 are set between the central region NS and the right end region R1 and the left end region L1, respectively. Hereinafter, these are collectively referred to as regions NS, R1, R2, L1, and L2. Based on the estimated deviation amount of the vehicle 13 from the lane center line CL, the vehicle position detection unit 6b detects which region NS, R1, R2, L1, L2 the vehicle 13 is located on. . The vehicle position detection unit 6 b always detects the position of the vehicle 13 in order to operate the steering device 8.

  The steering amount calculation unit 6c (corresponding to the steering amount calculation means) determines the position of the vehicle 13 from the lane center line CL based on the left-right direction position on the travel lane DP of the vehicle 13 detected by the vehicle position detection unit 6b. When the deviation occurs, the operation amount of the steering device 8 is calculated. The steering driver 7 described above operates the steering device 8 based on the operation amount calculated by the steering amount calculation unit 6 c and the detected values by the steering angle sensor 2 and the vehicle speed sensor 3 to correct the traveling position of the vehicle 13. The steering amount calculation unit 6c calculates the operation amount of the steering device 8 based on the shift position, the steering operation angle, the accelerator opening, the yaw rate, the steering torque, and the like of the vehicle 13 in addition to the detection value described above. Also good.

The driving operation evaluation unit 6d (corresponding to the driving evaluation means) is based on the deviation amount from the center of the travel lane DP of the vehicle 13 and the number of deviations during a predetermined time detected by the vehicle position detection unit 6b. Driving evaluation information is formed by evaluating driving operations by thirteen drivers. The driving operation evaluation unit 6d evaluates the driving operation by the driver of the vehicle 13 every time a predetermined time elapses (sampling time is, for example, at a cycle of 20 seconds). Specifically, the driving operation evaluation unit 6d uses a deduction method based on how many times the region 13 of the regions NS, R1, R2, L1, and L2 is located on the travel lane DP. Driving evaluation information is formed by scoring.
As shown in FIG. 4, for example, during a predetermined time, the vehicle 13 is positioned four times in the right end region R1, four times in the left end region L1, four times in the right connection region R2, and four times in the left connection region L2. An example will be described. When the vehicle 13 is located in the right end region R1 or the left end region L1, the deduction coefficient is set to -2, and 2 points are deducted for each position. Further, when the vehicle 13 is located in the right connection region R2 or the left connection region L2, the deduction coefficient is set to -1, and one point is deducted for each position. Further, when the vehicle 13 is located in the central area NS, no deduction is performed. Therefore, in the above case, the total deduction points are 24 points.

The deduction based on the deviation of the vehicle 13 on the travel lane DP described above is increased or decreased according to the time when the deviation is detected. That is, the above deduction points are converted based on the case where all deviations are detected for 60 minutes as a reference and according to each time when the deviations are detected for 60 minutes. Therefore, if all deviations are detected in 20 minutes, they are multiplied by 3 to give a total deduction of 72 points. When all the deviations are detected in 120 minutes and 240 minutes, they are multiplied by (1/2) and (1/4), respectively, and the total deduction points are 12 points and 6 points, respectively. When the deviation is detected in 60 minutes, the total deduction points are 24 points as they are.
The final evaluation score PT calculated by the driving operation evaluation unit 6d is calculated by subtracting the total deduction points from 100 points in each case. Therefore, when the time when the above-described deviation is detected is 20 minutes, 60 minutes, 120 minutes, and 240 minutes, the evaluation scores PT are 28 points, 76 points, 88 points, and 94 points, respectively, in this order.
The driving evaluation information formed by the driving operation evaluation unit 6d includes not only the above-described evaluation score PT but also a driving trajectory TR, an average driving position SA, a driving tendency TE, etc., as will be described later. The driving operation evaluation unit 6d may form driving evaluation information based on the number of times the steering device 8 is operated in order to correct the deviation of the vehicle 13 from the lane center line CL.

The image sound forming unit 6e forms notification image data and notification sound data for the display 11 and the speaker device 12 to notify the driver of the driving evaluation information formed by the driving operation evaluation unit 6d.
The display 11 displays the evaluation notification image SC shown in FIG. 5 based on the notification image data formed by the image / sound forming unit 6e. The evaluation notification image SC is formed by color-coded animation images, and the left and right white lines WR and WL, the lane center line CL, and the areas NS, R1, R2, L1, and L2 are represented on the travel lane DP. .
In the evaluation notification image SC, the average travel position SA of the vehicle 13 on the travel lane DP is displayed by a symbol imitating the shape of the vehicle. In the evaluation notification image SC, the travel locus TR of the vehicle 13 on the travel lane DP is displayed as a straight line or a curve. The travel trajectory TR is displayed by an animation extending from the lower side to the upper side in FIG. 5 in about 30 seconds. The travel locus TR is formed in a shape that connects the positions of the vehicle 13 every 20 seconds.
In addition, the evaluation score PT and the driving tendency TE described above are displayed at the lower end of the evaluation notification image SC. In the present embodiment, the driving tendency TE is indicated by the average travel position SA of the vehicle 13, and is performed by five-step display of right side, slightly right side, center, left side, and slightly left side. In FIG. 5, it is represented as slightly leftward.
Instead of the average travel position SA and the driving tendency TE based on the average travel position SA, the vehicle 13 may be displayed based on the position where the vehicle 13 is traveling most on the travel lane DP. Further, in addition to the display contents of the evaluation notification image SC described above, the number of operations of the steering device 8 operated by the steering driver 7 may be displayed.

On the other hand, the speaker device 12 generates an evaluation notification message based on the notification sound data formed by the image / sound forming unit 6e. As the evaluation notification message, for example, a message such as “I was traveling to the left” as a message regarding the driving tendency TE can be considered. The evaluation notification message may be, for example, “Today's score is 76 points” as a message related to the evaluation score PT. Further, for example, when the vehicle 13 is traveling to the left or slightly to the left, a message “Let's be aware of driving to the right next time” is generated, or the vehicle 13 is traveling in the center of the traveling lane DP. , The message “Please drive in this condition” may be generated.
The evaluation notification image SC and the evaluation notification message are preferably formed using a display image and a warning sound that are different from those generated when the steering device 8 is operated in order to alert the driver.

Next, based on FIG. 6, the driving | running evaluation control method by the traveling position controller 6 of this embodiment is demonstrated. Note that the control for steering the steered wheels 9 of the vehicle 13 by the steering device 8 is executed in parallel with the driving evaluation control by a control flow different from the driving evaluation control flow shown in FIG. In the operation evaluation control flow shown in FIG. 6, the routine from step S101 to step S105 is performed at a cycle of 20 seconds, but is not limited to this cycle.
First, the vehicle position detection unit 6b acquires travel image data formed by the image processing unit 6a (step S101). The vehicle position detection unit 6b forms vehicle position data based on the traveling image data, and whether or not there is a deviation in the vehicle 13 on the traveling lane DP, that is, the vehicle 13 is out of the regions R1, R2, L1, and L2. It is determined whether or not it is located in any of the above (step S102). When the vehicle 13 is located in the area NS, the process proceeds to step S105.

  When the vehicle 13 is located in any one of the regions R1, R2, L1, and L2, the travel lane DP has a curved shape, or a power pole, a pedestrian WP, and a bicycle in front of the vehicle 13 It is determined whether or not there is a peripheral factor such as the presence of an obstructing object such as the presence of an oncoming vehicle 14 that passes in front of the vehicle 13 (step S103). If there is at least one of the peripheral factors as described above, it is natural that the vehicle 13 deviates, and it is not necessary to deduct the evaluation score of the driving operation by the driver, so the process proceeds to step S105. When there are no peripheral factors, the deduction of the evaluation score of the driving operation is counted by the method described above (step S104). The driving operation evaluation unit 6d stores the deduction points counted for each routine. As described above, the driving operation evaluation unit 6d evaluates the driving operation by the driver of the vehicle 13 in consideration of the form of the travel lane DP, the presence or absence of an obstacle located in front of the vehicle 13, and the presence or absence of the oncoming vehicle 14. ing. The driving operation evaluation unit 6d may evaluate the driving operation by the driver in consideration of the traveling speed of the vehicle 13.

In step S105, it is determined whether or not the ignition switch 5 of the vehicle 13 has been operated from the on state to the off state. When the ignition switch 5 is not operated to the off state, the process returns to step S101. When the ignition switch 5 is operated to the off state, driving evaluation information is formed by the driving operation evaluation unit 6d (step S106). In the formation of the driving evaluation information, as described above, based on the time when the deviation of the vehicle 13 occurs, calculation of the evaluation score is performed by summing up the previous points stored in the driving operation evaluation unit 6d. The Further, a travel locus TR, an average travel position SA, a driving tendency TE, and the like are formed.
Thereafter, the driver 11 is notified of driving evaluation information through the display 11 and the speaker device 12 (step S107). The formation of the driving evaluation information and the notification of the driving evaluation information are performed because the driving position controller 6, the audio ECU 10, the display 11, and the speaker device 12 are operated for a predetermined time by a timer after the ignition switch 5 is operated to be in an OFF state. , Executed within the predetermined time.

  According to the present embodiment, the driving operation evaluation unit 6d that evaluates the driving operation by the driver of the vehicle 13 and forms the driving evaluation information based on the left-right direction position of the vehicle 13 with respect to the traveling lane DP detected by the in-vehicle camera 4. And the display 11 and the speaker device 12 for notifying the driver of the driving evaluation information formed by the driving operation evaluation unit 6d, the driver is related to the driving position of the vehicle 13 on the driving lane DP. You can recognize your own habits. For this reason, when the driver consciously corrects his / her own heel, the root cause of the vehicle 13 being biased in the left-right direction on the travel lane DP can be eliminated, and the safety of vehicle travel can be improved. it can.

Further, the driving operation evaluation unit 6d evaluates the driving operation by the driver of the vehicle 13 based on the deviation amount of the traveling lane DP from the lane center line CL and the number of deviations during a predetermined time. It is possible to accurately evaluate the driving operation by the driver and to form appropriate driving evaluation information.
Further, the vehicle position detection unit 6b is provided in the vehicle 13 and includes the in-vehicle camera 4 that images the travel lane DP, so that the position of the vehicle 13 on the travel lane DP can be accurately detected.

The in-vehicle camera 4 detects the form of the traveling lane DP, and the driving operation evaluation unit 6d evaluates the driving operation by the driver of the vehicle 13 in consideration of the form of the traveling lane DP detected by the in-vehicle camera 4. . As a result, for example, when the travel lane DP has a curved shape, the vehicle 13 inevitably travels outside the curve, and in this case, the evaluation score for driving operation is reduced. Thus, it is possible to accurately evaluate the driving operation by the driver.
The in-vehicle camera 4 detects the presence or absence of an obstacle such as a utility pole or a pedestrian WP located in front of the vehicle 13 on the travel lane DP, and the driving operation evaluation unit 6d detects the obstacle detected by the in-vehicle camera 4. The driving operation by the driver of the vehicle 13 is evaluated in consideration of the presence or absence of an object. As a result, when there is an obstacle in front of the vehicle 13, it is inevitable that the vehicle 13 will deviate to the right of the travel lane DP by traveling avoiding the obstacle. The driver's driving operation can be accurately evaluated without degrading the evaluation score.
The in-vehicle camera 4 detects the presence or absence of an oncoming vehicle 14 that crosses the vehicle 13, and the driving operation evaluation unit 6 d considers the presence or absence of the oncoming vehicle 14 detected by the in-vehicle camera 4. Evaluate the driving operation. Thereby, when there is an oncoming vehicle 14 such as a large truck that crosses the vehicle 13, it is inevitable that the vehicle 13 deviates to the left of the traveling lane DP by running avoiding the oncoming vehicle 14, In this case, it is possible to accurately evaluate the driving operation by the driver without deducting the evaluation score of the driving operation.

Further, the driving evaluation notification device 1 includes a display 11 provided in the passenger compartment 13a, and the display 11 is displayed on the display 11 by displaying a travel locus TR of the vehicle 13 on the travel lane DP. The driver who has seen the evaluation notification image SC can accurately know the travel position on the travel lane DP of the vehicle 13 he / she is driving.
Further, the display 11 displays the average travel position SA of the vehicle 13 on the travel lane DP, so that the driver who sees the evaluation notification image SC displayed on the display 11 shows a tendency of hesitation of his / her driving operation. It can be recognized accurately.
Further, the display 11 displays the evaluation score PT calculated based on the position of the vehicle 13 in the left-right direction with respect to the travel lane DP, so that the driver who viewed the evaluation notification image SC displayed on the display 11 can perform his / her driving. You can know the objective evaluation of the operation.

<Embodiment 2>
Based on FIG. 7 and FIG. 8, differences from the first embodiment will be described with respect to the vehicle driving evaluation apparatus 1 according to the second embodiment. The configuration of the vehicle driving evaluation apparatus 1 according to the present embodiment has the same configuration as that shown in FIG. Further, in the operation evaluation control flow shown in FIG. 7, the routine from step S <b> 201 to step S <b> 206 is performed at a cycle of 20 seconds as in the first embodiment.
First, the driving evaluation control method according to the present embodiment will be described with reference to FIG. Also in this embodiment, the control for steering the steered wheels 9 of the vehicle 13 by the steering device 8 is executed in parallel with the driving evaluation control by a control flow different from the driving evaluation control flow shown in FIG. Yes.

First, in step S201, it is determined whether or not the steering device 8 is in an inoperative state. When the steering device 8 is in the non-operating state, traveling image data formed by the image processing unit 6a is acquired (step S202). The vehicle position detection unit 6b forms vehicle position data based on the traveling image data, and determines whether or not the vehicle 13 is located in any one of the regions R1, R2, L1, and L2 (step S203). ). When the vehicle 13 is located in the area NS, the process proceeds to step S206.
When the vehicle 13 is located in any one of the regions R1, R2, L1, and L2, it is determined whether or not there is a peripheral factor as described in the first embodiment (step S204). If there is at least one of the peripheral factors, the process proceeds to step S206. When there are no peripheral factors, the deduction of the evaluation score for driving operation is counted as in the first embodiment (step S205).

In step S206, it is determined whether or not the ignition switch 5 of the vehicle 13 has been operated from the on state to the off state. If the ignition switch 5 has not been operated to the off state, the process returns to step S201. When the ignition switch 5 is operated to the off state, driving evaluation information is formed by the driving operation evaluation unit 6d (step S207). Thereafter, the driver 11 is notified of driving evaluation information through the display 11 and the speaker device 12 (step S208).
On the other hand, if it is determined in step S201 that the steering device 8 is in the operating state, the data detected in the previous routine (20 seconds before) continues as it is for the vehicle position data formed by the vehicle position detector 6b. After (step S209), the process proceeds to step S206. Thus, in the present embodiment, the driving operation evaluation unit 6d does not consider the position in the left-right direction of the vehicle 13 with respect to the travel lane DP when the steering device 8 is operating as an object for evaluation of the driving operation.

As shown in FIG. 8, in the evaluation notification image SC according to the present embodiment, the average travel position SA of the vehicle 13 on the travel lane DP and the travel locus of the vehicle 13 on the travel lane DP are the same as in the first embodiment. TR and driving tendency TE are displayed. As described above, in the present embodiment, the lateral position of the vehicle 13 with respect to the travel lane DP when the steering device 8 is operating is not subject to the evaluation of the driving operation, and the vehicle position data is the previous routine. Since the data detected at is continued as it is, the travel locus TR of the vehicle 13 does not include the correction of the travel position by the steering device 8. In the present embodiment, since the evaluation score is not calculated when the steering device 8 is operated, the evaluation score PT is not displayed.
Other configurations and functions of the vehicle driving evaluation apparatus 1 according to the present embodiment are the same as those in the case of the first embodiment, and thus further description thereof is omitted.

  According to the present embodiment, the driving operation evaluation unit 6d determines that the position of the vehicle 13 in the left-right direction relative to the travel lane DP when the steering device 8 is operating is not subject to the evaluation of the driving operation. Since the travel trajectory TR does not include the correction of the travel position by the steering device 8, the driver who sees the evaluation notification image SC displayed on the display 11 recognizes the tendency of his travel position more accurately. be able to.
