Description

  The present invention relates to a driving evaluation device and a driving evaluation method, and can be used, for example, to improve driving skills of a driver. The present invention detects the behavior of the vehicle related to the garage entry and / or the garage exit by the back by the operation information indicating the operation of the vehicle, and by evaluating the driver's driving from the detected behavior of the vehicle, The evaluation should not be different due to external factors so that the operation can be correctly evaluated as compared with the conventional case.

  2. Description of the Related Art Conventionally, a method for evaluating driving has been proposed in, for example, Japanese Patent Application Laid-Open No. 2002-154346 for the purpose of improving driving skills with respect to vehicles. In such an evaluation method, for example, a smooth driving without rapid acceleration / deceleration is evaluated as a good driving by detecting fuel consumption, acceleration, and the like.

  However, in such determination based on the evaluation of driving, there is a drawback that the determination result changes due to various external factors. That is, for example, even when traveling on the same road, the fuel consumption and acceleration / deceleration change due to the number of vehicles traveling depending on the traveling time zone, and the evaluation changes accordingly. Further, for example, on a road that repeatedly goes up and down, the fuel efficiency is naturally deteriorated, and acceleration / deceleration is repeated. Thus, a bad evaluation result is obtained as compared with the case of traveling on a flat road.

However, if it is possible to evaluate the driving more correctly than in the past without making the evaluation different due to such external factors, it is considered that this type of driving evaluation can be used more effectively. .
JP 2002-154346 A

  The present invention has been made in view of the above points, and proposes an operation evaluation apparatus and an operation evaluation method capable of correctly evaluating an operation as compared with the conventional one without making the evaluation different due to external factors. It is what.

In order to solve the above-described problem, according to an aspect of the present invention, there is provided a driving evaluation device that evaluates driving of a vehicle by a driver, which is registered in advance based on a current position detection result by a current position detecting unit. and at certain locations, from the information of the operation indicating an operation of the vehicle, detects the behavior of the vehicle according to the garage out by the garage and or back by back, the operation of the driver from the behavior of the vehicle that the detected A driving evaluation device for evaluating the above is provided.

In order to solve the above problem, according to another aspect of the present invention, there is provided a driving evaluation method for evaluating driving of a vehicle by a driver , based on a current position detection result by a current position detecting means in advance. said vehicle in registered specific location from the information of the operation indicating an operation of the vehicle, comprising the steps of behavior detection for detecting the behavior of the vehicle according to the garage out by the garage and or back by back, which is the detected And a step of evaluating the driver's driving from the behavior of the driver.

According to the configuration of the driving evaluation device, the behavior of the vehicle related to entering or leaving the garage due to the back is detected from operation information indicating the operation of the vehicle, and the driver is determined based on the detected behavior of the vehicle. If the driving is evaluated, it is possible to easily detect the behavior of the vehicle related to the garage entry by the back and / or the garage exit by the back, based on the unique behavior of the vehicle different from that at the time of traveling. In addition, when entering the garage with the back and / or leaving the garage with the back, unlike during driving, the influence of external factors such as traffic of other vehicles is small, and the evaluation differs depending on these external factors. Thus, the operation can be correctly evaluated as compared with the conventional case.

With the configuration of the driving evaluation method described above, it is possible to provide a driving evaluation method capable of correctly evaluating driving as compared with the prior art without making the evaluation different due to external factors.

  According to the present invention, it is possible to correctly evaluate the operation as compared with the prior art without making the evaluation different due to external factors.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

(1) Configuration of Example FIG. 2 is a block diagram showing a driving evaluation apparatus according to an example of the present invention. The driving evaluation device 1 is mounted on a vehicle and evaluates the driving of a user related to the vehicle.

  Here, in the driving evaluation apparatus 1, the controller 2 is a controller provided in a vehicle on which the driving evaluation apparatus 1 is mounted, and constitutes a so-called keyless entry system together with an electronic key detection mechanism and the like (not shown). The vehicle is controlled to operate by operating the key.

  The controller 2 detects a unique identification code provided in the electronic key in the process related to the electronic key, and thereby identifies the user related to the electronic key. The controller 2 notifies the driving evaluation apparatus 1 of user identification information DU based on the detected identification code. Further, the controller 2 is set to be operable in this way, and notifies the operation evaluation apparatus 1 of operation information D1 indicating various operations by the user. For this reason, the controller 2 detects the operation of the parking brake 3 and the switching operation of the gear 5 by the user, and notifies the driving evaluation device 1 as operation information D1. Further, acceleration / deceleration is detected by the acceleration sensor 4A to detect a brake operation by the user, and further, a change in the steering wheel is detected by the steering angle sensor 4B to detect a user's steering operation, and these are used as operation information D1. Notify the driving evaluation device 1. Further, the travel distance of the vehicle is detected at regular time intervals by the vehicle speed pulse SP, and notified to the driving evaluation apparatus 1 as operation information D1.

  The driving evaluation apparatus 1 selectively accumulates and holds the operation information D1 obtained from the vehicle in this way, and compares the accumulated and held operation information D1 with the operation information D1 obtained sequentially. Thus, the user's driving is evaluated and the evaluation result is notified to the user.

  Here, in the driving evaluation device 1, the interface (IF) 6 is an input / output circuit for various data from the controller 2, and the hard disk device (HDD) 7 records a processing program related to the processing of the driving evaluation device 1. Hold. The hard disk device 7 selectively records operation information D1 notified from the controller 2 via the interface 6 for each user identified by the user identification information DU under the control of the central processing unit (CPU) 8. Hold. The display device 10 is formed of, for example, a liquid crystal display device, and displays an evaluation of operation under the control of the central processing unit 8. The memory 9 constitutes a work area of the central processing unit 8.

  The central processing unit 8 selectively records the operation information D1 obtained sequentially by executing the processing program recorded on the hard disk device 7, and sequentially inputs the operation information D1 to the recorded operation information D1. The operation information D1 and the operation information D1 recorded in the hard disk device 7 are determined to evaluate the driving. In this embodiment, the processing program is provided by being installed in the hard disk device 7 in advance. However, it is provided by downloading via a network such as the Internet in place of such provisional installation. Alternatively, it may be provided by installation via a recording medium. In such a recording medium, various recording media such as an optical disk, a magnetic disk, and a memory card can be widely applied.

  Here, the central processing unit 8 secures a temporary recording area by a fixed recording area in the hard disk device 7, and sequentially records the operation information D1 obtained sequentially in the temporary recording area while performing this operation. 3 and 4 are executed by monitoring the information D1 in the above manner, so that the operation information D1 at the time of entering the garage by the back and at the time of taking out the garage by the back is selectively recorded on the hard disk device 7, thereby the user. Is selectively recorded in the hard disk device 7 when the garage is put into the garage and removed from the garage. Here, the garage entry and the garage exit by the back mean that the vehicle travels backward by the back gear, enters the garage, and removes the garage from the rear.

  Here, when the parking brake 3 is operated by the user and the vehicle is parked, the central processing unit 8 executes the processing procedure of FIG. That is, when the processing procedure shown in FIG. 3 is started, the central processing unit 8 moves from step SP1 to step SP2, where the operation of the parking brake 3 by the user is detected and recorded in the hard disk device 7 in the subsequent step SP3. Based on the operation information D1, it is determined whether or not the user has selected the back gear for a certain period of time before operating the parking brake 3 and the vehicle has traveled backward. If a negative result is obtained here, the central processing unit 8 moves from step SP3 to step SP4, deletes the operation information D1 that has been cyclically recorded in the hard disk device 7 until then, and then moves to step SP5. The processing procedure ends. In step SP3, even if the central processing unit 8 is operated when the back gear is operated, the central processing unit 8 clearly determines the change in the travel distance and the steering angle by the back gear detected by the operation information D1. When it is not possible to determine that the vehicle is in the garage, the process proceeds from step SP3 to step SP4, and this processing procedure is terminated, as in the case where the back gear is not operated. In this case, for example, the case where the back gear is simply selected, the case where the vehicle passes through the target point, the vehicle is parked in parallel, or the like corresponds to this case.

  On the other hand, if an affirmative result is obtained in step SP3, the central processing unit 8 moves from step SP3 to step SP6. In this case, it is determined that the user enters the garage in the back, and the user operates the parking brake. After recording the operation information D1 in a certain period until the user identification information DU for each user, the process proceeds to step SP5 and the processing procedure is terminated. In this fixed period, a fixed period including the time point when the vehicle is temporarily stopped is assigned to start garage entry by back.

  Thereby, as shown in FIG. 5, the central processing unit 8 detects the garage entry by the back on the basis of the operation of the parking brake and the operation of the back gear, and after starting the garage entry by the back at the time point t1, The behavior of the vehicle until the insertion is completed is recorded for each user.

  By the way, depending on the user, the garage may be put in from the head and the vehicle may be turned back when the garage is taken out. As a result, when the parking brake 3 is released by the user, the central processing unit 8 executes the processing procedure of FIG. 4 to detect garage removal due to the back and record the behavior of the vehicle.

  That is, in this case, the central processing unit 8 moves from step SP11 to step SP12, detects the release of the parking brake 3 by the user, and in the subsequent step SP13, the back gear is selected by the user. It is determined whether the vehicle has traveled backward. If a negative result is obtained here, the central processing unit 8 moves from step SP13 to step SP14, deletes the operation information D1 that has been cyclically recorded in the hard disk device 7 until then, and then moves to step SP15. The processing procedure ends.

  Even in this case, even if the back gear is operated, the central processing unit 8 clearly determines the change in the travel distance and the steering angle due to the back gear detected by the operation information D1, thereby clearing the garage. If it cannot be determined, the process proceeds from step SP13 to step SP14 and the processing procedure is terminated, as in the case where the back gear is not operated. Here, in this case, for example, the case where the back gear is simply selected, the case where the vehicle parked at the dead end is driven back to the street, and the like are applicable.

  On the other hand, if an affirmative result is obtained in step SP13, the central processing unit 8 moves from step SP13 to step SP16, determines that the user has left the garage in the back, and after the user operates the parking brake, After the operation information D1 in the period is recorded for each user by the user identification information DU, the process proceeds to step SP15 and the processing procedure is terminated. Therefore, in this fixed period, a period including an operation for temporarily stopping the vehicle is allocated in order to start traveling.

  As a result, the central processing unit 8 detects the garage exit due to the back as shown in FIG. 6 based on the operation of the parking brake and the operation of the back gear, and starts the garage exit at the back at the time t1. After that, the behavior of the vehicle until the garage removal is completed is recorded for each user.

  In this way, for each user, the behavior of the vehicle at the time of entering and leaving the garage is recorded for each user, and when the number of records for each user reaches a certain number or more, the central processing unit 8 determines from the record relating to the corresponding user. The oldest record is deleted, so that a certain number of the latest records are held in the hard disk device 7 for each user.

  Further, when recording the behavior of the vehicle at the time of entering and leaving the garage in this way, the central processing unit 8 records the corresponding past behavior recorded on the hard disk device 7 by executing the processing procedure shown in FIG. By comparing with the above, the user's driving for entering and leaving the garage is evaluated.

  In other words, the central processing unit 8 starts this processing procedure by starting the engine by the user and moves from step SP21 to step SP22. From the processing result by the processing procedure described above with reference to FIGS. If a negative result is obtained here, step SP22 is repeated, and this processing procedure is terminated when the user stops the engine.

  On the other hand, if a positive result is obtained in step SP22, the central processing unit 8 moves from step SP22 to step SP23, and from the behavior of the vehicle recorded in the hard disk device 7, the detected garage or garage according to the back. Measure the time required for delivery. Further, in the subsequent step SP24, the number of turnovers at the time of entering or leaving the garage by the detected back is measured from the behavior of the vehicle recorded in the same hard disk device 7. Further, in the subsequent step SP25, the magnitude of shock at the time of stop is measured from the detection result of acceleration by the acceleration sensor 4A for the brake operation at the time of entering and leaving the garage.

  In this way, the central processing unit 8 measures the behavior of the vehicle by the user's operation for garage entry and garage exit, and digitizes these measurement results in the subsequent step SP26. Specifically, the central processing unit 8 sets the measurement result so as to give a higher evaluation as the time required for entering or leaving the garage becomes shorter as the time required for entering or leaving the garage is shorter. Turn into. In addition, the smaller the number of turnovers, the more smoothly the garage can be put in and the garage can be removed, and the measurement result is digitized so as to give a higher evaluation accordingly. Thus, for example, as shown in FIG. 7A, the highest evaluation value is given when the car can be put into the garage without being turned over. Further, as shown in FIGS. 7B and 7C, when the number of times of turnover increases, the evaluation value is set lower as the number of times of turnover increases. In addition, when sudden acceleration is detected at the time of entering or leaving the garage, when the vehicle body collides with an obstacle, the vehicle body is likely to collide with the obstacle, and the brake is operated in a hurry. In this case, the evaluation value is reduced as sudden deceleration is detected.

  In this way, the central processing unit 8 calculates the evaluation values by digitizing the measurement results obtained in step SP23, step SP24, and step SP25, and calculates the total evaluation value by weighting and adding these evaluation values.

  In the subsequent step SP27, the central processing unit 8 records and holds the evaluation value calculated in this way in the hard disk device 7 together with the corresponding operation information D1.

  Further, in the subsequent step SP28, the central processing unit 8 sequentially loads the past vehicle operation information D1 related to the current user from the vehicle operation information D1 for each user recorded in the hard disk device 7, and loads this information. The behavior of the vehicle based on the past operation information D1 is compared with the behavior of the vehicle based on the current operation information D1, and the behavior of the past vehicle that can be determined to be garage entry and garage exit under substantially the same conditions is detected. Specifically, in the case of garage entry, for example, the change in the direction of the vehicle from the state temporarily stopped for garage entry to the state where the parking brake is operated is detected, and garage entry under almost the same conditions is detected. To do. In the case of leaving the garage, the change in the direction of the vehicle from the state in which the parking brake is released to the time when the back is ended and the vehicle starts to move forward is compared to detect garage removal under almost the same conditions. .

  Further, the central processing unit 8 compares the past comprehensive evaluation value recorded for garage entry and garage removal under the same conditions detected in this way with the overall evaluation value calculated in step SP26, and continues. In step SP29, the comparison result is displayed on the display device 10, and then the process proceeds to step SP30 to end the processing procedure. Therefore, the central processing unit 8 displays that the operation has been successful, for example, when the current evaluation value is larger than the maximum value of the evaluation values related to the past record, by comparing the evaluation values. In this case, the determination may be made on the basis of an average value of past evaluation values. On the other hand, when the current evaluation value is smaller than the maximum value of the past evaluation values or the average value of the past evaluation values, the user is notified that the driving has become unsatisfactory. In these cases, when the current evaluation value is significantly different from the past evaluation value, the notification to the user is emphasized.

(2) Operation of the embodiment In the above configuration, in the driving evaluation apparatus 1 (FIG. 2), the operation information D1 indicating the driver's operation is notified from the controller 2 of the vehicle, and the driving is performed based on the operation information D1. An operation of the parking brake 3 by hand is detected. Further, when the operation of the parking brake 3 is detected, the operation of the back gear is detected, thereby detecting the garage entry due to the back and the garage exit due to the back (FIGS. 3 and 4).

  However, in the case of entering and leaving the garage by such a back, for example, the amount of traffic of the vehicle on the general road varies depending on the time zone by, for example, taking the vehicle into and out of the garage at home. Even in this case, it is a vehicle operation in a situation where the traffic volume does not change so much, and it can be said that it is a driving operation under almost the same conditions each time, with little change due to external factors.

  Thereby, in this driving evaluation device 1, the user's driving is evaluated from the behavior of the vehicle in the garage entering by the back and the garage taking out by the back detected in this way. As a result, in this embodiment, the evaluation can be correctly evaluated as compared with the prior art so that the evaluation does not differ due to external factors.

  That is, in the driving evaluation device 1, the operation information D1 in the garage entry and the garage removal by the back detected in this way is recorded in the hard disk device 7 for each user by the user identification information DU related to the keyless entry system. . In addition, the time required to enter the garage by the back, the time required to exit the garage by the back, the number of turnovers, and the shock at the time of stopping are measured (Fig. 1), and the total evaluation value is measured by these, and compared with the evaluation values related to past records The driving quality is evaluated.

  In this way, driving evaluation is performed by putting the garage in the back and taking out the garage in the back. In the driving evaluation apparatus 1, the garage is put in the garage by the back and the back is operated based on the operation of the parking brake and the operation of the back gear by the user. Thus, it is possible to easily and reliably detect garage entry by back and garage exit by back to evaluate driving.

  Further, at this time, if the vehicle is simply driven backward by the steering distance sensor 4B, the distance traveled by the back gear, for example, the vehicle is excluded from the evaluation target by the garage entry by the back and the garage exit by the back. Thus, the accuracy of evaluation related to driving is improved.

  In addition, the user identification information DU related to the keyless entry system is used effectively, and driving is evaluated for each user, so that even when a single vehicle is shared by multiple users, it is appropriate for each user. You can evaluate driving.

(3) Effects of the embodiment According to the above configuration, the behavior of the vehicle related to the garage insertion by the back and the garage removal by the back is detected from the operation information indicating the operation of the vehicle, and the driving is performed based on the detected behavior of the vehicle. By evaluating the hand driving, it is possible to correctly evaluate the driving as compared with the related art without making the evaluation different due to external factors.

  In addition, by detecting the behavior of the vehicle related to the garage entry and the garage exit due to the back based on the operation of the back gear and the parking brake, the garage entry by the back and the garage exit by the back can be easily and reliably performed. Detect and evaluate driving.

The driving evaluation device 21 detects position information of the current position by the GPS receiving unit 22 constituting the car navigation device, and puts the garage in the back and puts out the garage in the back at a specific location registered by the user in advance based on the position information. Is detected. Further, based on the position detection result, driving is evaluated by comparison with the operation information D1 at the time of entering the garage and taking out the garage related to the same place in the past. The driving evaluation device 21 according to the present embodiment is a central processing unit that detects a garage entry by a back and a garage exit by a back at a specific location with reference to the current position detected by the GPS receiver 22 in this way. Except for the point that the processing of 28 is different, it is configured the same as the driving evaluation apparatus 1 of the first embodiment.

  In this embodiment, on the basis of the current position detected by the current position detection means, the evaluation of driving is performed by detecting the garage insertion by the back and the garage removal by the back and evaluating the driving only for a specific location. The driving environment can be set constant, and driving can be evaluated with higher accuracy.

  In the above-described embodiment, the case where the driving is evaluated based on the number of turnovers, the required time, etc. has been described, but the present invention is not limited to this, for example, the posture before entering the garage, the posture after entering the garage, Various evaluation methods can be widely applied, for example, when an optimal predicted route is calculated from the distance between and the like, and driving is evaluated based on this predicted route.

  Further, in the above-described embodiment, the case where the evaluation of driving is notified by comparing the garage entry by the back and the garage removal by the back with the past records is described, but the present invention is not limited to this, and a certain evaluation criterion is used. It can be widely applied to the case of setting and notifying the evaluation of driving by comparison with this evaluation standard.

  Further, in the above-described embodiment, the case where the driving is evaluated for both the garage entry by the back and the garage removal by the back has been described.
