Description

  The present invention relates to a driving support device that evaluates driving and prevents danger.

As a conventional technique, a technique described in Patent Document 1 below is known. This technology maps vehicle operation reference values based on road map information stored in advance in a storage medium (corresponds to maps), and corrects this based on real-time information indicating the current road conditions ( (See paragraph “0011” of Patent Document 1).

(See paragraph “0012” etc.).
JP 2004-249821 A

  However, since the technique described in Patent Document 1 outputs the result from the display unit and the voice output unit after scoring, the driving results in a low scoring result, that is, overspeed, sudden braking, etc. The driver cannot know the fact until after dangerous driving occurs. Therefore, the driver understands the scoring results, and when passing the route next time, based on the previous scoring results, the driver recognizes the place where he / she tends to overspeed and the place where he / she tends to brake suddenly. There is a need to. This may be a burden on the driver who is always forced to make an appropriate determination based on various information.

  The present invention has been considered in view of such problems, and an object of the present invention is to provide a driving support device that reduces the burden of recognizing a dangerous place of the driver.

  A driving support apparatus that solves the above-described problems includes a notification unit, a storage unit, a current position information acquisition unit, a traveling state information acquisition unit, a dangerous driving determination unit, and a notification control unit. Among these, the notification means is a means capable of notifying the driver of information, the storage means is a means capable of storing information, and the current position information acquisition means acquires current position information which is information relating to the current position of the vehicle. The traveling state information acquisition unit is a unit that acquires traveling state information that is information relating to the traveling state of the vehicle. Note that the “information relating to the running state of the vehicle” includes, for example, the running speed, the degree of acceleration / deceleration, the traction state, the steering angle information, the running position on the roadway, and the like.

  The dangerous driving determination means determines whether a dangerous driving condition has occurred based on the driving condition information acquired by the driving condition information acquisition means, and determines that the dangerous driving condition has occurred. The current position information acquired by the current position information acquisition unit when the error occurs is stored in the storage unit as dangerous part information, and the dangerous information indicating the type of dangerous driving state is stored in the storage unit in association with the dangerous part information. It is a means to make. Further, the notification control means detects the approach of the vehicle to the dangerous place based on the current position information acquired by the current position information acquisition means and the dangerous place information stored in the storage means, and the fact of the approach. And means for causing the notification means to notify the danger information stored in the storage means.

  According to such a driving support device, when the vehicle approaches a dangerous place (a place where a dangerous driving state has occurred) stored in the storage unit, dangerous information (information indicating the type of the dangerous driving state) is notified. Therefore, the driver can know the existence of the dangerous place even if he forgets about the existence of the dangerous place. That is, it is possible to reduce the dangerous places that the driver must be aware of, and to reduce the burden on the driver. Further, if the driving support device of the present invention is used by a plurality of drivers, the danger information is also received when a vehicle driven by another driver approaches a location where another driver has generated a dangerous driving state. Informed. Therefore, safety is further increased.

  The driving support device may further include an ideal travel state information acquisition unit that acquires ideal travel state information that is information related to the travel state of an ideal vehicle. Then, when making the above-described determination, the dangerous driving determination unit compares the driving state information acquired by the driving state information acquisition unit with the ideal driving state information acquired by the ideal driving state information acquisition unit. It is good to be.

If it is in this way, it can be easily determined that the dangerous driving state has occurred by examining the degree of deviation between the driving state information and the ideal driving state information.
Another driving support apparatus that solves the above-described problem includes a notifying unit, a storing unit, a current position information acquiring unit, a driving operation information acquiring unit, a dangerous driving determination unit, and a notification control unit. Among them, the notification means, the storage means, and the current position information acquisition means are the same as those of the driving support device described above, but the driving operation information acquisition means is driving operation information that is information relating to the actual driving operation of the driver It is a means to acquire. The “driving operation” mentioned here means an operation necessary for driving such as a steering wheel operation, an accelerator operation, a brake operation, a shift operation, and a winker operation.

  The dangerous driving determination means determines whether or not a dangerous driving state has occurred based on the driving operation information acquired by the driving operation information acquisition means, and determines that the dangerous driving state has occurred. Means for storing the current position information acquired by the current position information acquisition means in the storage means as dangerous part information when the occurrence of the accident occurs, and storing the dangerous information indicating the type of the dangerous driving state in correspondence with the dangerous part information in the storage means It is. Further, the notification control means detects the approach of the vehicle to the dangerous place based on the current position information acquired by the current position information acquisition means and the dangerous place information stored in the storage means, and the fact of the approach. And means for causing the notification means to notify the danger information stored in the storage means.

  Also with such a driving support device, when the vehicle approaches a dangerous place (a place where a dangerous driving state has occurred) stored in the storage means, dangerous information (information indicating the type of the dangerous driving state) is notified. Therefore, the driver can know the existence of the dangerous place even if he forgets about the existence of the dangerous place. That is, it is possible to reduce the dangerous places that the driver must be aware of, and to reduce the burden on the driver. Further, if the driving support device of the present invention is used by a plurality of drivers, the danger information is also received when a vehicle driven by another driver approaches a location where another driver has generated a dangerous driving state. Informed. Therefore, safety is further increased.

  The driving support device may further include ideal driving operation information acquisition means for acquiring ideal driving operation information that is information related to ideal driving operation. Then, when making the above-described determination, the dangerous driving determination unit compares the driving operation information acquired by the driving operation information acquisition unit with the ideal driving operation information acquired by the ideal driving operation information acquisition unit. It is good to be.

If it is in this way, it can be easily determined that the dangerous driving state has occurred by examining the degree of deviation between the driving operation information and the ideal driving operation information.
By the way, when the dangerous driving determination means performs the above determination, it may be determined in consideration of other information, for example, environmental information that is information related to the external environment of the vehicle. Here, “information related to the external environment of the vehicle” means, for example, weather, traffic jam information, regulation information, date information, and the like.

  If such information is taken into account and the dangerous driving determination means makes the above-mentioned determination, for example, on a rainy day, it is possible to make a determination with stricter determination criteria when the speed is exceeded. A suitable decision can be made.

  In addition, when the dangerous driving determination means makes the above determination, the determination is performed in consideration of other information, for example, driver operation information that is information related to the driver's operation other than the driver's driving operation. Good. The information related to the driver's operation other than the driver's driving operation is, for example, an operation on the audio device, an operation on the navigation device, an operation on the cigarette lighter, an operation on the window open / close switch, It means snoozing.

  If the dangerous driving determination means makes the above-described determination in consideration of such information, for example, when the driver looks away, the point where the driver looks away is stored, and then the vehicle travels through the point. When doing so, the driver is informed of the point where he / she has looked away before (approximately the point where he / she tends to look away). In this way, matters that are determined as points where more dangerous driving conditions occur are widened, which helps to improve safety.

  By the way, the dangerous driving determination means may perform the above-described determination in real time (simultaneously with the driving operation of the driver), but information necessary for the determination is stored in the storage means, and a predetermined timing is set. Thus, the determination may be made using the information stored in the storage means. The term “predetermined timing” as used herein refers to, for example, when driving is completed, after traveling a predetermined section, after traveling a predetermined distance, after a predetermined time has elapsed, It means when you want.

  In order to perform the above-described determination in real time (during driving), it is necessary that the processing capability of the processor constituting the dangerous driving determination means is sufficient. However, if the information necessary for the determination is stored in the storage means and the determination is made at a predetermined timing, the processor has a lower processing capacity than the case where the processing must be performed in real time. There may be. Therefore, if it becomes like this, it will become easier to manufacture a driving assistance device, and it will contribute to cost reduction.

  In addition, the notification control unit may notify the notification unit of a plurality of dangerous spot information and the danger information stored in the storage unit at a predetermined timing. The term “predetermined timing” as used herein refers to, for example, when driving is completed, after traveling a predetermined section, after traveling a predetermined distance, after a predetermined time has elapsed, It means when you want.

  If it is in this way, the driver can know a plurality of dangerous spot information and dangerous information all at once, so that he can know his driving tendency and an area where dangerous spots are concentrated.

  By the way, the above-described function as the dangerous driving determination means and the function as the notification control means may be realized by a program. If such a program is executed by a computer built in the driver assistance device, the same effects as those of the driving assistance device described above can be obtained. Further, the program can be distributed using a network or the like, and the replacement of the program in the driving support device is easier than the replacement of the parts. Therefore, it is possible to easily improve the function of the driving support device.

A route calculation process for calculating the route, a route guidance process for guiding the route by displaying the calculated route on the display unit 26 or outputting it as a voice to the voice output unit 27, and the like are executed.

[Description of operation]
Next, various processes executed by the control unit 29 will be described. General processing as a navigation device, such as current position display processing for displaying the current position, route calculation processing for calculating the optimum route to the destination, route guidance processing for guiding the route to the destination, etc. Description of is omitted.

(1) Travel Information Recording Process First, the travel information recording process will be described with reference to the flowchart of FIG. The running information recording process is started when power supply to the navigation device 20 is started.

  When starting the execution of the travel information recording process, the control unit 29 first determines whether or not the current position of the vehicle is a recording start point (S110). The “recording start point” is a point set in advance by the driver, and coordinates indicating the point are stored in the SRAM of the control unit 29. Note that the current position when a specific switch of the operation switch group 22 is operated by the user may be treated as a recording start point.

  In S110, when it is determined that the current position of the vehicle is the recording start point (S110: Yes), the process proceeds to S120, and when it is determined that the current position of the vehicle is not the recording start point (S110: No). This step (S110) remains.

  In S120, driving information recording is started. This “travel information” refers to information related to the driving state of the vehicle (for example, travel speed, degree of acceleration / deceleration, traction information, steering angle information, travel position on the roadway), and information related to driving operation (handle operation, accelerator operation, Brake operation, shift operation, blinker operation, etc.), driver operation information other than driving operation (operation on the audio device, operation on the cigarette lighter, operation on the window open / close switch, looking away, snoozing, etc.), vehicle Information on the external environment (for example, weather, traffic jam information, regulation information, date and time information, etc.) and current position information. Among these pieces of information, information related to the driving operation and operation information of the driver other than the driving operation are acquired from various ECUs, sensors, and the like via the in-vehicle LAN communication unit 33. Information about the external environment of the vehicle is acquired from the information center via the external communication device 24. The travel information recording destination is the SRAM of the control unit 29 (an external storage device such as a hard disk may be connected to the navigation device 20 and used as a recording destination).

  In subsequent S130, it is determined whether or not the current position of the vehicle is the recording end point. The “recording end point” is a point set in advance by the driver, and coordinates indicating the point are stored in the SRAM of the control unit 29. Note that it may be determined that the current position of the vehicle has reached the recording end point by operating a specific switch of the operation switch group 22 by the driver.

  In S130, when it is determined that the current position of the vehicle is the recording end point (S130: Yes), the process proceeds to S140, and when it is determined that the current position of the vehicle is not the recording end point (S130: No). This step (S130) remains.

In S140, the recording of the travel information is ended, and the process returns to S110 described above.
(2) Driving Information Evaluation Process Next, the driving information evaluation process will be described using the flowchart of FIG. The running information evaluation process is started when a specific switch of the operation switch group 22 is operated by the driver. The execution of the travel information evaluation process may be started when the step S140 in the travel information recording process described above is performed.

When starting the execution of the travel information evaluation process, the control unit 29 first reads the travel information from the SRAM and develops it in the RAM (S210).
Subsequently, information necessary for driving evaluation is acquired from the map data storage medium via the map data input device 25 and developed in the RAM (S215). Here, “information necessary for driving evaluation” means information necessary for driving evaluation performed in the steps described later (excluding travel information read in S210). Specifically, ideal driving operation information (information on steering wheel operation, brake operation, accelerator operation, etc.), ideal driving state (traveling speed, degree of acceleration / deceleration, traction state, steering angle information, roadway information, etc. Traveling position, etc.).

  Subsequently, driving evaluation is performed (S220). This “driving evaluation” refers to traveling information developed in the RAM, ideal driving operation information and ideal traveling state information acquired via the map data input device 25, and information via the external communication device 24. Based on information obtained from the center, etc., evaluation is performed from the viewpoint of safety and comfort for passengers. Specifically, the information on the driving state of the vehicle (one of the information constituting the driving information) is compared with the ideal driving state information to determine the degree of deviation, and the information on the driving operation. This is performed by comparing (one of the information constituting the travel information) with ideal driving operation information and obtaining the degree of deviation. In addition, based on the degree of deviation and other information (information on the driver's operation other than driving operation, information on the external environment of the vehicle), for example, the point where sudden braking occurred, the point where skidding occurred, the vehicle Extract the points that are staggered, the points where traffic regulations were not observed, the points where the driver looked away, etc.

In subsequent S230, information related to the location where the dangerous driving state has occurred (position specifying information and the type of dangerous driving) is stored in the SRAM of the control unit 29 by the driving evaluation in S220.
In subsequent S240, the driver is inquired whether or not to notify the evaluation result. Specifically, it is realized by displaying a message such as “Do you want to notify the driving evaluation result?” On the display unit 26 and monitoring that the specific button of the operation switch group 22 is pressed. As a result, when it is determined that the driver wants to notify the evaluation result (S240: Yes), the process proceeds to S250, and when the driver determines that the notification of the evaluation result is not desired (S240). : No), this process (travel information evaluation process) is terminated.

  In S250, the evaluation result is notified, and this processing (running information evaluation processing) ends. In addition, as a notification method, it performs by making the display part 26 display the place which a driver | operator should be careful with a process table.

Here, a specific example of the evaluation result displayed on the display unit 26 will be described with reference to the screen example of FIG.
As shown in FIG. 4, the control unit 29 displays the vehicle speed transition in a line graph on the first level from the top on the display unit 26, and displays a route point (for example, a departure point, a facility name, Intersection name, traffic obstruction point, right / left turn point, etc.) are displayed. Then, the route time, average speed, sudden braking presence / absence, skidding presence / absence of other dangers, and the like are displayed in tabular form.

When such an evaluation result is displayed on the display unit 26, the present process (running information evaluation process) ends.
(3) Warning Process Next, the warning process will be described with reference to the flowchart of FIG. The warning process is executed when power supply to the navigation device 20 is started.

  When starting the execution of the warning process, the control unit 29 reads information on the location where the dangerous driving state has occurred from the SRAM, and determines whether or not the vehicle has approached the location where the dangerous driving state has occurred (S310). The term “approached” here means that a point before a predetermined distance (for example, 100 m) has reached a point where a dangerous driving state has occurred, or a predetermined time (for example, 10 seconds) to a point where a dangerous driving state has occurred. It means that the point has been reached.

  In S310, when it is determined that the vehicle has approached the place where the dangerous driving state has occurred (S310: Yes), the process proceeds to S320, and it is determined that the vehicle has not approached the place where the dangerous driving state has occurred. If it does (S310: No), stay in this step (S310).

  In S320, the driver is informed of the fact that the vehicle is close to the location where the dangerous driving state has occurred and the contents of the dangerous driving state. A specific notification method causes the display unit 26 to display a message indicating the contents of danger and operations necessary to avoid the danger. The message is output from the voice output unit 27. When these notifications are finished, the process returns to S310 described above.

  Here, a specific example of the message displayed on the display unit 26 will be described with reference to the explanatory diagram of FIG. As shown in FIG. 6, the control unit 29 causes the display unit 26 to display a map near the current position, an icon 51 indicating the position of the vehicle, and a balloon 52. Note that the balloon 52 has a message “notice sudden braking!” And the balloon point of the balloon 52 is a point corresponding to the message.

[Effect of the embodiment]
According to such a navigation device 20, when the vehicle approaches a dangerous place (a place where a dangerous driving state has occurred), since dangerous information (indicating the type of dangerous driving state) is notified, Even if you forget about the dangerous part, you can know the existence of the dangerous part. That is, it is possible to reduce the dangerous places that the driver must be aware of, and to reduce the burden on the driver. If the navigation device 20 is used by a plurality of drivers, the danger information is also notified when a vehicle driven by another driver approaches a location where another driver has generated a dangerous driving state. . Therefore, safety is further increased.

  Further, the control unit 29 performs the driving evaluation by comparing the information on the actual driving state of the vehicle with the ideal driving state information, or comparing the information on the actual driving operation with the ideal driving operation information. Therefore, objective evaluation can be performed.

  In addition, the control unit 29 performs driving evaluation using information on the external environment of the vehicle acquired through the external communication device 24 (for example, accident information, traffic jam information, weather information, regulation information, etc.). Therefore, it is possible to make a determination that is more realistic.

  In addition, the control unit 29 obtains the operation information of the driver other than the driving operation acquired through the in-vehicle LAN communication unit 33 (operation on the audio device, operation on the cigarette lighter, operation on the window opening / closing switch, looking away, Since the driving evaluation is also performed using a snooze or the like), it is possible to make a more realistic determination.

  In addition, the control unit 29 displays the result of the driving evaluation on the display unit 26. That is, the locations where the dangerous driving state has occurred are displayed together. For this reason, the driver can know his / her driving tendency and an area where dangerous places are concentrated.

[Other Embodiments]
(1) In the above embodiment, the running information evaluation process is started when a specific switch of the operation switch group 22 is operated by the driver, and the driving evaluation and the dangerous driving state occur in the process. Are registered (S220, S230), these may be executed in the travel information recording process. That is, driving evaluation or the like may be performed simultaneously with acquisition of travel information (in real time).

If it becomes like this, the time for performing driving | operation evaluation etc. separately becomes unnecessary, and it can provide a driver | operator evaluation result immediately to a driver | operator after completion | finish of driving | operation.
(2) During the driving evaluation in the driving information evaluation process (S220), the driving evaluation is performed using the driving information stored in the past at the same point and the result of the past driving evaluation. Also good. If it becomes like this, more appropriate evaluation can be performed.

  (3) When registering information on a place where a dangerous driving state has occurred in the travel information evaluation process (S230), information such as a time zone and a departure time is also registered, and the information is also taken into consideration in S310 in the warning process. It is good to make a judgment of. That is, it is good to register the information of the location where the dangerous driving state has occurred with a condition and perform the warning process in consideration of the condition.

If this is the case, a warning can be given more appropriately.
