Description

  The present invention relates to a vehicle safe driving promotion system for promoting safe driving and economical driving of a vehicle.

  In-vehicle safe driving evaluation devices have been known to promote improvements in driver driving skills and improve safe driving and economic driving. The emphasis was on collecting and evaluating safe driving evaluation tables at the operation manager's office after operation.

  Also, in recent years, while driving a vehicle, there are things that convey safe driving evaluation (overspeed, sudden acceleration / deceleration, etc.) to the driver in real time by voice or screen display, mainly giving a warning to the driver when the threshold is exceeded, This gives a negative impression to the driver.

  According to a research result published by the research team of the National Institute for Physiological Sciences (Okazaki City, Aichi Prefecture) in the US scientific journal “Newton” dated April 4, 2008, “When someone else praises, "The same part is activated when cash is received," he said, "Praise is scientifically supporting the long-standing hypothesis of giving people spiritual encouragement."

  Further, Patent Literature 1 proposes a driving psychology determination device and a driving psychology determination method, and a driving support device and a driving support method that analyze driver psychology from changes in the inter-vehicle distance and perform appropriate advice.

In this conventional example, for example, an average inter-vehicle distance for each speed range based on a driver-specific inter-vehicle history and an average inter-vehicle distance for each vehicle speed calculated at the time of the current driving are compared in each speed range, and the psychological state of the driver is determined. When it is determined that there is a disturbance such as irritation due to changes in the inter-vehicle distance, it is output to the driver side from the navigation device display or voice guidance speaker as an example. Recognize it, or have an air conditioner and an audio device, and when a psychological disorder is detected, activate the air conditioner to blow cool air to the driver, or activate the audio device to play music The judgment result is made to be recognized by the driver.
JP 2003-51097 A

  However, the prior art disclosed in Patent Document 1 also only allows the driver to recognize the determination result when the disturbance of the psychological state is determined, and does not give the driver spiritual encouragement by praise.

  The vehicle safe driving promotion system disclosed in the present disclosure is intended to provide a technique capable of improving the driver's awareness of safe driving by giving the driver mental encouragement.

  According to one aspect, the vehicle safe driving promotion system is communicable with a server of the management center, and includes an in-vehicle device provided with a storage unit, a notification unit mounted on the vehicle, a vehicle mounted on the vehicle, Driving state acquisition means for acquiring a state, the storage means stores a safe driving threshold value and a determination threshold value of the vehicle, and the in-vehicle device has the driving state information acquired by the driving state acquisition means as the safety information. It is determined whether or not it is within the driving threshold and the determination result is transmitted to the server, and the server accumulates the transmitted determination result, and creates safe driving evaluation history information of the driver from the accumulated determination result. Input to the storage means of the in-vehicle device, the in-vehicle device determines the driving situation of the driver from the safe driving threshold, the driving state information, and the safe driving evaluation history information, When the turning situation is within the determination threshold stored in the storage means, a message is given to the driver via the notification means, and when the driving situation of the driver is outside the determination threshold, the notification means is provided. It is characterized by giving advice to the driver.

  According to the safe driving promotion system disclosed in the present disclosure, it is possible to give spiritual encouragement to the driver through praise (message). As a result, the driver's voluntary safe driving improves safety driving awareness, and traffic accidents Reduction is expected.

  In addition, for example, by accumulating data that was given up and evaluating the driver's performance, and reflecting this in salary etc., the driver's motivation can be maintained and improved, and fuel-saving driving effects from safe driving are also expected. Have advantages.

  Further, by giving advice for promoting safe driving together with a message, guidance for safe driving is achieved.

  Since the driver's performance evaluation can be performed in detail based on the safe driving evaluation history information, the driver's motivation can be further improved.

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

  FIG. 1 shows a block diagram of an embodiment of a vehicle safe driving promotion system, in which 1 is a vehicle (own vehicle), and an in-vehicle device 3 is mounted on the vehicle 1.

  The in-vehicle device 3 includes, in the telematics ECU 7, a GPS receiving unit that receives a GPS signal from a GPS (Global Positioning System) satellite (not shown) by the GPS antenna 5 and measures the position information and time information of the vehicle 1. Measures the position information of latitude and longitude associated with the movement of the vehicle 1 based on the GPS signal, and measures the time information based on the GPS signal.

  The in-vehicle device 3 is connected to a display unit 9 composed of a display or the like mounted in the passenger compartment, and a speaker 11 to be described later. On the map displayed on the display unit 9, the position information of latitude and longitude is displayed. Based on this, the position of the vehicle 1 is displayed.

  The in-vehicle device 3 includes a communication interface unit 13, and a memory card (storage medium) 15 is detachably set in a card slot (not shown) of the in-vehicle device 3.

  Furthermore, an input terminal 17 for inputting a work state (work contents) at each work point is connected to the in-vehicle device 3 as an example. The input terminal 17 is connected to a work state in a vehicle stop state, that is, Four input keys 19, 21, 23, 25 for setting and canceling “loading”, “unloading”, “break”, and “waiting” are provided.

  Then, with the memory card 15 set in the in-vehicle device 3, the driver patrols a plurality of work points according to a route designated in advance, stops the vehicle 1 at each work point, and performs loading and unloading. When the work state is set by pressing any of the input keys 19, 21, 23, 25, the telematics ECU 7 determines the position information and time information of the vehicle 1 at that time and the set work state. (For example, “loading”) is recorded in the memory card 15 as vehicle information (operation data).

  Furthermore, the vehicle 1 is equipped with a vehicle speed sensor 27 that detects the vehicle speed and a acceleration sensor 29 that detects the acceleration / deceleration state of the vehicle 1 as a traveling state acquisition unit, and these are also connected to the telematics ECU 7.

  In addition, the vehicle 1 and the server 31 of the management center are connected by wireless packet communication as an example, and the telematics ECU 7 obtains the position information and time information of the vehicle 1 from the GPS satellite when the vehicle 1 starts running. The information is transmitted to the server 31 side via the communication interface unit 13 and recorded in the memory card 15, and thereafter, the position information and time information of the traveling vehicle 1 are periodically (for example, every 10 minutes), the server 31 side. Are recorded on the memory card 15.

  Further, as described above, every time the driver presses one of the input keys 19, 21, 23, 25 to set the working state, the telematics ECU 7 sends the position information of the vehicle 1 at that time to the server 31 side. And the time information, the set work state, etc. are transmitted as vehicle information. On the server 31 side, vehicle information data transmitted from the vehicle 1 is accumulated.

  In addition, the server 31 and a personal computer (terminal; hereinafter referred to as “PC”) 33 in the office of the operation manager of the vehicle 1 are connected via the Internet 35. The transmitted vehicle information can be grasped in real time via the personal computer 33.

  The safe driving promotion system according to the present embodiment has the following characteristics in addition to the above-described configuration in order to promote safe driving and economic driving.

  First, the threshold setting examples shown in FIGS. 2 to 4 are set and stored in the memory (storage means) of the in-vehicle device 3.

  These threshold setting examples are created by the personal computer 33 and input to the memory of the in-vehicle device 3 via the server 31.

  The “speed speed threshold setting example” shown in FIG. 2 evaluates the safe driving of the vehicle speed on a general road, and waits for a signal in one travel section from the start to the stop of the vehicle 1, for example, at an intersection. After the vehicle 1 has started, the vehicle speed is ranked until the next stop (travel speed = 0 km / h) at an intersection or the like.

  Rank 1 is the highest safe driving evaluation when the vehicle 1 complies with the speed limit of 60 km / h for general roads, and rank 2 is the safety when the driver runs at a speed exceeding 60 km / h and less than 66 km / h. In the driving evaluation, the safe driving evaluation is lowered every time the rank is increased to rank 5. In addition, the excess determination time in ranks 2 to 5 is 5 seconds as an example.

  Therefore, for example, when the maximum speed of 70 km / h is detected by the vehicle speed sensor 27 for 5 seconds continuously in one traveling section, the safe driving evaluation becomes rank 3.

  “Threshold setting example of sudden start and sudden acceleration” shown in FIG. 3 is for performing safe driving evaluation of start and acceleration of the vehicle. For example, the driver suddenly accelerates while driving and the acceleration of 0.230 G is an acceleration sensor. If detected at 29, the safe driving evaluation is rank 2.

  The “sudden deceleration threshold setting example” shown in FIG. 4 is used to perform a safe driving evaluation of deceleration of the vehicle. For example, when the acceleration sensor 29 detects a sudden deceleration of 0.380 G by sudden braking during driving, Driving evaluation is rank 4.

  The vehicle speed value and acceleration / deceleration value of rank 1 of each “threshold value setting example” are input and set in the memory of the in-vehicle device 3 as the safe driving threshold value and the economic driving threshold value. And the detected value of the acceleration sensor 29 and each “threshold value setting example”, the case where the detected value is the vehicle speed value and the acceleration / deceleration value within the rank 1 is determined to be within the threshold value, and the detected value is the vehicle speed within the ranks 2 to 5 A value and an acceleration / deceleration value are determined to be outside the threshold value.

  Further, “real-time message / advice timing example” and “stop message / advice timing example” shown in FIGS. 5 and 6 and “comment example” shown in FIG. Has been.

  These “message / advice timing example” and “comment example” are also created by the personal computer 33 and input and set in the memory of the in-vehicle device 3 via the server 31. This specification and claims In this description, the “message” is a comment notified to give up a driver who has performed safe driving, and is a comment of rank 1 in FIG. The “advice” is a comment notified to encourage the driver to drive safely, and is a comment of ranks 2 to 5 in FIG.

  “Real-time message / advice timing example” in FIG. 5 gives a message to the driver on the items of sudden acceleration and sudden deceleration in real time while driving, and gives advice on the items of sudden acceleration, sudden deceleration and speed compliance. During traveling, the in-vehicle device 3 compares the detection values of the vehicle speed sensor 27 and the acceleration sensor 29 with the threshold value setting examples of FIGS. 2 to 4, and the detection value of the acceleration sensor 29 is within the threshold value, that is, When the acceleration / deceleration value is within the rank 1, it is assumed that acceleration / deceleration is good, and the message of rank 1 shown in FIG. 7 (comment to give up "Your smooth driving is excellent") from the speaker 11 to the driver in real time. It has come to inform.

  On the other hand, if any of the detected values of acceleration / deceleration and vehicle speed is out of the threshold during running, that is, if a vehicle speed value or deceleration value within ranks 2 to 5 is detected, ranks 2 to 2 shown in FIG. Advice (comment to encourage safe driving) corresponding to 5 is notified to the driver.

  On the other hand, the “message at stop / advice timing example” in FIG. 6 indicates that a message is sent to the driver in terms of speed compliance when stopping for each traveling section described above. The in-vehicle device 3 compares the detected value of the vehicle speed sensor 27 with the threshold value setting example in FIG. 2 while traveling, and determines whether the detected value is within the threshold value or outside the threshold value. When the determination is made, when the vehicle 1 is stopped, a message of rank 1 shown in FIG. 7 (a comment to give up “I am hard at driving safely”) is notified to the driver from the speaker 11.

  The telematics ECU 7 of the in-vehicle device 3 sends the message / advice result (rank) via the communication interface unit 13 together with the current position information and time information of the vehicle 1 each time the message and advice are notified. The data is transmitted to the server 31 side and recorded on the memory card 15. On the server 31 side, the result of the message / advice transmitted from the vehicle 1 is accumulated, and the operation manager can analyze and evaluate such data via the personal computer 33 to evaluate the driver's performance. It can be done.

  Accordingly, the telematics ECU 7 first transmits vehicle position information and time information from a GPS satellite to the server 31 via the communication interface unit 13 and records them in the memory card 15 when the vehicle 1 starts to travel.

  Each time the driver presses one of the input keys 19, 21, 23, 25 during operation to set the working state, the telematics ECU 7 sends the position information and time information of the vehicle 1 at that time to the server 31. The set work state is transmitted as vehicle information, and the vehicle information is recorded in the memory card 15. The operation manager can quickly grasp the vehicle information transmitted to the server 31 via the personal computer 33.

  Further, as described above, on the personal computer 33 in the operation manager's office, the threshold setting examples in FIGS. 2 to 4 and the “real-time message / advice timing example” and “stop message / advice timing” in FIG. 5 and FIG. An “example” and an “comment example” in FIG. 7 are created and transmitted to the vehicle 1 via the server 31 before the vehicle 1 starts to travel, and are input and set in the memory of the in-vehicle device 3.

  At the same time, the vehicle speed value and acceleration / deceleration value of rank 1 in the threshold setting example are transmitted from the personal computer 33 to the vehicle 1 via the server 31 as safe driving and economic driving threshold values (step S1 in FIG. 8). It is input and set in the memory of the in-vehicle device 3 (step S2).

  Next, in step S3, the telematics ECU 7 of the in-vehicle device 3 grasps the driving state of the driver from the detection values of the vehicle speed sensor 27 and the acceleration sensor 29 during the driving (step S3), and the detection value of the acceleration sensor 29 is a threshold value. Whether the acceleration / deceleration value is within rank 1, or not (step S4). When it is determined in step S4 that the detected value of the acceleration sensor 29 is within the threshold value, the telematics ECU 7 determines that the driver's acceleration / deceleration driving is good, and the message of rank 1 shown in FIG. Announce the comment to give up) to the driver. Further, when the detection value of the vehicle speed sensor 27 in one traveling section is within the threshold value, the message of rank 1 shown in FIG. 7 (comment to give up) is similarly given from the speaker 11 to the driver when the vehicle 1 stops. Notification is made (step S5).

  On the other hand, if any of the detected values of acceleration / deceleration and vehicle speed is out of the threshold during running, that is, if a vehicle speed value or deceleration value within ranks 2 to 5 is detected, ranks 2 to 2 shown in FIG. Advice (comment urging safe driving) corresponding to 5 is notified to the driver (step S6).

  Each time the telematics ECU 7 notifies the message and advice, together with the position information and time information of the vehicle 1 at that time, the message / advice result (rank) is sent to the server 31 side via the communication interface unit 13. The data is transmitted and recorded in the memory card 15 (step S7). Then, the server 31 side accumulates data of the result of the message / advice transmitted from the vehicle 1 (step S8), and thereafter repeats the above-described routine until the operation of the vehicle 1 is completed. The person analyzes and evaluates such data via the personal computer 33 to evaluate the driver's performance (steps S9 and S10).

  In this way, the safe driving threshold and the economic driving threshold are input and set in the memory of the telematics ECU 7 (on-vehicle device 3) via the memory card 15 or the server, and when the driving state of the driver is within the threshold, the driver gives up. Since the message is sent, the driver can be given spiritual encouragement by praise. As a result, the driver's voluntary safe driving improves the safety driving awareness and the traffic accident is expected to be reduced.

  In addition, for example, by accumulating data that was given up and evaluating the driver's performance, and reflecting this in salary etc., the driver's motivation can be maintained and improved. Furthermore, safe driving and economic driving are Since there is a common point in that “does not drive suddenly”, there is an advantage that a fuel-saving driving effect by safe driving is also expected.

  Instead of the method of inputting and setting the safe driving threshold and the economic driving threshold to the in-vehicle device 3 from the personal computer 33 of the operation manager's office via the server 31, the storage device such as a memory card is not used via the server. The safe driving, economic driving threshold, “threshold setting example”, “message / advice timing example”, and “comment example” may be directly input and set from the personal computer of the operation manager to the memory of the in-vehicle device. Each time the telematics ECU 7 notifies the message and advice, the telematics ECU 7 records the message / advice result together with the position information and time information of the vehicle 1 at that time on the memory card. The memory card taken out from the apparatus may be mounted on a personal computer in the office to accumulate data, and the data may be analyzed and evaluated.

  FIG. 9 is a “stop message / advice timing example” different from the “stop message / advice timing example” of FIG.

  As described above, the server 31 accumulates data of the result of the message / advice transmitted from the vehicle 1 (in-vehicle device 3), but the server 31 is based on the result of the message / advice transmitted from the in-vehicle device 3. Then, safe driving evaluation history information and economic driving evaluation history information (hereinafter referred to as “personal data”) for each driver are created and updated.

  When the operation manager starts traveling of the vehicle 1, the personal data is transmitted from the personal computer 33 in the office via the server 31 to each vehicle 1 (for each driver) so that the individual personal data is stored in the in-vehicle device 3. It is input and set for each (memory of the telematics ECU 7).

  Thus, the personal data is an average value of the past 10 rank results transmitted in each item of rapid acceleration, rapid deceleration, and speed compliance, for example, the past 10 times in the rapid acceleration and rapid deceleration items. If the rank result of “Rank 1” is 4 times, “Rank 2” is 4 times, and “Rank 3” is 2 times, the personal data of the driver in the items of rapid acceleration and rapid deceleration is “Rank 1” .8 ".

  Similarly, in the item of speed compliance, if the rank results of the last 10 transmitted “Rank 3” were 6 times and “Rank 4” was 4 times, the driver in the speed compliance item The personal data is “rank 3.4”.

  As described above, the telematics ECU 7 evaluates the driving state of the driver and notifies the driver of the message and advice through the speaker 11, and further uses the personal data as one of the evaluation criteria for the driver.

  That is, as described above, in accordance with the “real-time message / advice timing example” in FIG. 5 while traveling, the telematics ECU 7 uses the “threshold setting example” in FIG. 2 to FIG. 4 and the “comment example” in FIG. A message is sent to the driver in real time if it is within the above-mentioned safe driving threshold and economic driving threshold, and if it is outside the threshold, advice is given to the driver in real time.

  On the other hand, during traveling, the telematics ECU 7 calculates a difference between the ranking of the driver according to the “threshold setting example” and personal data.

  As an example, as shown in FIG. 9, in the items of rapid acceleration and rapid deceleration, a message is notified that the difference of “+1” or more is within the determination threshold, and the difference of “−1” or less is outside the determination threshold. As a result, the driver is notified of advice.

  In the speed compliance item, the difference of “−2” or less is outside the determination threshold, and the personal computer 33 is set to notify the driver only when the difference is outside the determination threshold.

  FIG. 10 is an example of an actual “evaluation example at the time of stopping” at the time of stopping. As shown in the drawing, the difference between the personal data and the current ranking is “+1” in the items of sudden acceleration and sudden deceleration, respectively. In the speed compliance item, the difference between the personal data and the current time is “−2”, indicating that the driver is advised that it is out of the determination threshold. .

  11 is an example of “message / advice method” at the time of stoppage. As shown in FIG. 10, for example, when the evaluation in the item of rapid deceleration is “+2”, the message is “very good deceleration operation”. It has come to be notified. When the difference is “0”, the message / advice is not given because it is neither within the determination threshold nor outside the determination threshold.

  When there are items of message and advice, both the message and advice are notified.

  Since the present embodiment is configured as described above, the threshold setting examples in FIGS. 2 to 4 and the “real-time message / advice timing example”, “stop message / advice timing example” in FIG. 5 and FIG. “Comment example” of FIG. 11 and “Message / advice method” of FIG. 11 are created, and these are transmitted to the vehicle 1 via the server 31 before the vehicle 1 starts running, and input and set in the memory of the in-vehicle device 3 (Steps S1 and S2 in FIG. 12).

  Next, in step S3 in FIG. 12, the telematics ECU 7 grasps the driving state of the driver from the detected values of the vehicle speed sensor 27 and the acceleration sensor 29 during the traveling, and the detected value of the acceleration sensor 29 is within the threshold value, that is, the rank. Whether the acceleration / deceleration value is within 1 is monitored (step S4). When it is determined in step S4 that the detected value of the acceleration sensor 29 is within the threshold value, the telematics ECU 7 determines that the driver's acceleration / deceleration driving is good, and the message of rank 1 shown in FIG. Announce the comment to give up) to the driver.

  On the other hand, if any of the detected values of acceleration / deceleration and vehicle speed is out of the threshold during running, that is, if a vehicle speed value or deceleration value within ranks 2 to 5 is detected, ranks 2 to 2 shown in FIG. Advice (comment urging safe driving) corresponding to 5 is notified to the driver (step S6).

  At the same time, during traveling, the telematics ECU 7 calculates the difference between the driver ranking and the personal data according to the “threshold setting example”.

  When the vehicle 1 is stopped in one travel section, if the difference is within the determination threshold in the items of rapid acceleration, rapid deceleration, and speed compliance, a message is sent to the driver (step S5), and the speed compliance is confirmed. Only when there is a difference of “−2” or less in the item, the driver is notified of advice (step S6).

  Each time the telematics ECU 7 notifies the message and advice, the message / advice result (rank) is sent to the server 31 via the communication interface unit 13 together with the position information and time information of the vehicle 1 at that time. The data is transmitted and recorded in the memory card 15 (step S7). Then, the server 31 side accumulates data on the result of the message / advice transmitted from the vehicle 1 and updates the personal data based on the result (step S8). Thereafter, the operation is continued until the operation of the vehicle 1 is completed. After the operation is repeated, the operation manager analyzes and evaluates such data via the personal computer 33 to evaluate the driver's results (steps S9 and S10).

  As described above, in the present embodiment, the safe driving threshold value, the economic driving threshold value and the personal data are input and set to the memory of the telematics ECU 7 (the in-vehicle device 3) from the personal computer 33 of the operation manager's office via the server 31 to the driver. When the driving state of the vehicle is within this threshold, or when it is within the determination threshold based on personal data, a message to praise the driver is sent, so that the driver can be given spiritual encouragement by praise. As a result, the driver's voluntary safe driving improves safe driving awareness and is expected to reduce traffic accidents.

  In addition, the driver's performance evaluation can be performed in detail based on personal data. By reflecting this in salary etc., the driver's motivation can be further improved, and the fuel-saving driving effect by safe driving is also improved. Has an expected advantage.

  Furthermore, as other application examples, for example, safe driving and economic driving thresholds may be set on the in-vehicle device side, road conditions are selected on the in-vehicle device, and messages / advice according to the weather and traffic conditions are performed. May be.

  Furthermore, based on the personal data, it is possible to improve the driver's motivation further by constructing so as to actively give up when a low-evaluated item becomes good even a little.

  In the embodiment, a personal computer is used as a terminal on the operation manager side. However, the terminal is not limited to a personal computer, and may be a terminal such as a mobile phone, and the communication method to the terminal is not limited to the Internet. Other communication methods may be used.

  Moreover, although the said embodiment used the acceleration sensor, it is not restricted to this, For example, you may obtain | require a speed change from a speed sensor, and may calculate an acceleration.

  Furthermore, the present invention can be applied not only to passenger cars and commercial vehicles (trucks and the like) but also to construction machines, for example.
