Description

  The present invention relates to an in-vehicle device and an information notification method for notifying a driver of information received from a center.

  In recent years, with the advent of the ubiquitous network society, information terminals are ubiquitous in every place of the living environment, and the user can use various services without being aware of it. In particular, telematics services, which are information services for automobiles, are rapidly spreading in in-vehicle terminals.

  Examples of telematics services include weather forecasts, traffic jam information, email browsing, etc., and useful information for the driver is distributed in large quantities in real time from the center to the in-vehicle device.

  On the other hand, a driver who is driving maximizes visual information collection and is in an environment where it is easy to feel stress both mentally and physically. In this way, when the driving of the car itself is in a state of excessive information, if the driver is further notified of the large volume of information delivered from the center, the driver will fall into an extreme amount of information, and in the worst case There is a risk that it may interfere with driving and lead to a serious accident.

  In the existing vehicle-mounted device, various types of information distributed from the center are notified to the driver through a limited narrow vehicle-mounted screen. For example, the passenger is identified and, depending on the identified passenger, from the center. A technique for restricting notification (output restriction) of distributed information is also disclosed (see, for example, Patent Document 1).

  To give a specific example, when there is a passenger, the driver can be controlled not to notify the e-mail delivered from the center to the display of the vehicle-mounted device or to automatically read out. We provide suitable information in consideration of passengers to protect the privacy of the passengers.

Information may be distributed unilaterally from the distribution server, or may be distributed by a request signal from the in-vehicle device to the distribution server. Furthermore, when a user is registered in the in-vehicle device, it is automatically registered in the distribution server of the center, and the distribution server may select information to be distributed according to the user registration information. However, the information related to user registration is not limited to the above information, and the information distributed by the center is not limited to the above information.

  Such an in-vehicle device has a history DB that is a history storage unit that stores a history viewed by a driver for information received from outside in the past. Specifically, the history DB includes “weather information, 5”, “information about the current position” as “items indicating information distributed from the center in the past,“ viewing count ”indicating the number of times the driver has browsed”. , 20 ”,“ when there is a passenger 2 ”,“ hobby (music), 30 ”,“ news, 13 ”,“ travel route information, 25 ”,“ mail, 11 ”, and the like. Note that the “when there is a passenger” stored here indicates the number of times the information distributed from the center is browsed when there is a passenger.

  The in-vehicle device having such a configuration receives information distributed from the outside (for example, the center), and gives priority to notifying the driver of the received information based on the history stored in the history DB. A degree is given (see (1) in FIG. 1). For example, when the in-vehicle device receives “mail, weather, traffic jam information, latest hit music, sports news”, etc. from the center, the in-vehicle device is stored in the history DB in descending order (hobby, travel route information, current position information). Give priority to received information based on news, email, weather information, passengers, etc.). In this example, the in-vehicle device has priority as “mail (priority level 5), latest hit music (priority level 4), traffic jam information (priority level 3), sports news (priority level 2), weather (priority level 1)”. Give a degree.

  Then, the in-vehicle device detects the traveling state of the vehicle (see (2) in FIG. 1), and in the form suitable for the detected traveling state, from the information with high priority among the information given priority. Refer to the driver in order ((3) in FIG. 1).

  For example, when the vehicle speed information obtained from the vehicle speed sensor is 0 km / h, the in-vehicle device detects the traveling state of the vehicle as being stopped, and in order from “mail (priority 5)” having higher priority, Notify the driver that the e-mail has been received (or read out the contents of the e-mail) via voice through the speaker, and the message that the e-mail has been received (or the contents of the e-mail) on the display of the car navigation device. Display and notify the driver.

  In addition, for example, when the vehicle speed information obtained from the vehicle speed sensor is a value greater than 0 km / h, the in-vehicle device detects that the vehicle is in the running state and has a high priority “mail (priority 5 ) "In order, the driver is notified of the fact that" mail has been received (or reading out the contents of the mail) "only by voice through the speaker.

  As described above, the in-vehicle apparatus according to the first embodiment gives priority to information received based on information distributed from the center in the past, and gives priority in a format suitable for the driving state. Among the information, the driver is notified in order from the information with the highest priority. As a result, it is possible to notify only useful information to the driver while ensuring the driver's safe driving.

[Configuration of in-vehicle device]

For example, a steering sensor or the like may be connected to another sensor installed in a general vehicle. Good.

  The seat sensor 11 is a device that is installed in each seat in the vehicle and detects whether or not a person is sitting. Specifically, the seat sensor 11 is installed in each of the driver seat, the passenger seat, and the rear seat, and detects whether or not a person is seated based on the weight. For example, when the seat sensor 11 detects a certain weight (for example, 30 kg or more) continuously for a certain time (for example, 2 minutes), the seat sensor 11 detects that a person is sitting and notifies the vehicle-mounted device 20. .

  The car navigation device 12 includes a display, a touch panel, GPS (Global Positioning System), VICS (Vehicle Information and Communication System), and the like, and displays and outputs high-precision map information. Specifically, the car navigation device 12 displays the road to the destination selected by the user, the current position, road information on which the vehicle is traveling (for example, a right turn lane, an uphill, etc.), GPS, VICS, etc. The high-accuracy map information is acquired and displayed on a display or a touch panel, and the vehicle-mounted device 20 is notified.

  The vehicle speed sensor 13 is a device that detects the speed of the vehicle. Specifically, the vehicle speed sensor 13 is connected to a travel control device that controls the travel of the vehicle, detects the travel speed of the vehicle and the travel distance of the vehicle, and notifies the in-vehicle device 20 of the detected various information.

  The turn signal sensor 14 is a device that detects a driver's turn signal operation. Specifically, the winker sensor 14 is connected to the steering winker, detects that the driver has operated the right winker or the left winker, and notifies the in-vehicle device 20.

  The shift lever sensor 15 is a device that detects a driver's shift lever operation. Specifically, the shift lever sensor 15 is connected to a shift lever in a vehicle and detects a current shift lever (for example, a drive, a back, etc.) to be mounted on the vehicle. The device 20 is notified. The parking brake sensor 16 is a device that detects a driver's parking brake operation. Specifically, the parking brake sensor 16 detects whether the parking brake is ON or OFF, and notifies the vehicle-mounted device 20 of the detection.

  The speaker 17 is a device that outputs an audio signal into the vehicle. Specifically, the speaker 17 is installed in a car door, a rear seat, or the like, and outputs an audio signal output from the in-vehicle device 20 described later to the inside of the vehicle, and navigation information output from the car navigation device 12 or the like. Is also output as an audio signal in the car.

  The display 18 has a touch panel and the like, and is a device that displays and outputs various images. Specifically, the display 18 outputs an image signal output from an in-vehicle device 20 described later into the vehicle. Further, the display 18 may be a display of the car navigation device 12 or may be a display different from the car navigation device 12 (for example, a head-up display).

  The in-vehicle device 20 is a device that notifies the driver of various information distributed from the center, and in particular, a history DB 21, an information receiving unit 22, a passenger detection unit 23, a traveling state detection unit 24, and a priority level. It has the grant part 25 and the notification part 26.

  History DB21 memorizes the history which the driver browsed about the information received from the outside in the past. Specifically, as illustrated in FIG. 3, the history DB includes “items indicating information distributed from the center in the past and“ viewing count ”indicating the number of times the driver browses” as “weather information, 5 ”,“ Information about the current position, 20 ”,“ When there is a passenger 2 ”,“ Hobby (music), 30 ”,“ News, 13 ”,“ Traveling route information, 25 ”,“ Mail, 50 ”, etc. Remember. Note that “when there is a passenger” stored here indicates the number of times the information distributed from the center is browsed when the passenger is present. FIG. 3 is a diagram illustrating an example of information stored in the history DB.

  The information receiving unit 22 receives information distributed from the center. Specifically, the information receiving unit 22 receives “mail, weather information, sports news, latest hit chart, traffic jam information”, etc., as shown in FIG. Then, the received distribution information is notified to the priority assigning unit 25 described later. FIG. 4 is a diagram illustrating an example of information received from the center.

  The passenger detection unit 23 detects whether or not the passenger is a passenger. Specifically, the passenger detection unit 23 is connected to the seat sensor 11, and passenger information indicating whether or not there is a passenger is determined according to the presence or absence of the passenger detected by the seat sensor 11. The degree giving unit 25 is notified.

  The traveling state detection unit 24 detects the traveling state of the vehicle when information is received by the information receiving unit 22. Specifically, when the information receiving unit 22 receives information, the traveling state detection unit 24 is configured to detect vehicle speed information obtained from the vehicle speed sensor 13, turn signal information obtained from the turn signal sensor 14, and shift lever sensor. From the shift lever information obtained from 15 or the like, it is detected whether the vehicle is in a stopped state, is turning right, is backed, or is stopped, and notifies the notification unit 26 described later.

  For example, the traveling state detection unit 24 is traveling when the vehicle speed information obtained from the vehicle speed sensor 13 is greater than 0 km / h, and is stopped when the speed information is 0 km / h. Detect that it is inside. In addition, when the right or left turn signal operation signal is obtained from the turn signal sensor 14, the traveling state detection unit 24 is in a case where the vehicle is turning right or left, and no turn signal operation signal is obtained from the turn signal sensor 14. Detects that the vehicle is going straight. Further, the traveling state detection unit 24 indicates that the vehicle is traveling when a driving lever signal such as a drive is obtained from the shift lever sensor 15, and the parking state or neutral signal is obtained from the shift lever sensor 15. When the vehicle is stopped and a back lever signal is obtained from the shift lever sensor 15, it is detected that the vehicle is backing.

  Further, the running state detection unit 24 detects whether the parking brake information obtained from the parking brake sensor 16 is ON or OFF, and notifies the notification unit 26 described later of the detected parking brake information.

  The priority provision part 25 provides the priority notified to a driver with respect to the information received by the information reception part 22 based on the log | history memorize | stored in log | history DB21. Specifically, in the priority assigning unit 25, the information received by the information receiving unit 22 is “mail, weather information, sports news, latest hit chart, traffic jam information”, and the information stored in the history DB 21 is “ Weather information, 5 ”,“ Information about current position, 20 ”,“ When there is a passenger 2 ”,“ Hobby (music), 30 ”,“ News, 13 ”,“ Traveling route information, 25 ”,“ Mail ” , 50 ”. In this case, since the priority assigning unit 25 stores “2 when there is a passenger” in the history DB 21, privacy information among the received information is “priority 2”. That is, the order of priority to be given varies depending on whether the passenger detection unit 23 detects that there is a passenger and when it is detected that there is no passenger.

  For example, when the passenger detection unit 23 detects that there is a passenger, the priority assigning unit 25 assigns a priority to privacy-related information as usual, and, as shown in FIG. 5), latest hit chart (priority level 4), traffic jam information (priority level 3), sports news (priority level 2), weather information (priority level 1) "and priorities are given and notified to the notification unit 26. FIG. 5 is a diagram illustrating an example in which priority is given when there is a passenger.

  In addition, when the passenger detection unit 23 detects that there is no passenger, the priority assigning unit 25 is given a priority of 2 for the privacy-related information. “Sports news, latest hit chart, traffic jam information”, “mail” is given a priority of 2. For example, as shown in FIG. 6, the priority assigning unit 25 selects “latest hit chart (priority 5), traffic jam information (priority 4), sports news (priority 3), mail (priority 2), weather Information (priority 1) "and priority are given to the notification unit 26. FIG. 6 is a diagram illustrating an example in which priority is given when there is no passenger.

  The notification unit 26 notifies the driver in order from the information with the highest priority among the information given priority by the priority giving unit 25 in a format suitable for the driving state detected by the driving state detection unit 24. . Specifically, when the traveling state detecting unit 24 detects that the traveling state of the vehicle is stopped, the notifying unit 26 indicates “mail (priority) having a high priority given by the priority providing unit 25. In order from “degree 5)”, the driver is notified by voice through the speaker 17 that “e-mail has been received (or reading out the contents of the email)” and the display 18 or the like is notified that “e-mail has been received (or E-mail content) ”is displayed and the driver is notified.

  In addition, when the traveling state detecting unit 24 detects that the traveling state of the vehicle is stopped, the notification unit 26 has a high priority given by the priority providing unit 25 “mail (priority 5)”. In order, the driver is notified of the fact that the mail has been received (or the reading of the mail content) only by voice through the speaker 17.

  In addition, the notification unit 26, in the case where it is detected that the vehicle traveling state detected by the traveling state detection unit 24 is stopped and the parking brake is OFF, the text in order from the information with the highest priority. When it is detected that the running state of the vehicle displayed on the display 18 by the data and detected by the running state detection unit 24 is stopped and the parking brake is ON, the information with the highest priority is ordered. The text data and image data can be displayed on the display 18 to notify the driver.

[Processing by in-vehicle device]
Next, processing by the in-vehicle device will be described with reference to FIGS. Here, the overall processing flow of the in-vehicle device according to the first embodiment will be described with reference to FIG. 7, and the flow of information notification processing in the in-vehicle device according to the first embodiment will be described with reference to FIG.

(Overall processing flow)
First, the overall processing flow of the in-vehicle apparatus according to the first embodiment will be described with reference to FIG. FIG. 7 is a flowchart illustrating the flow of processing in the in-vehicle device according to the first embodiment.

  As shown in FIG. 7, when the vehicle-mounted device 20 downloads (DL) information from the center (Yes at Step S101), the in-vehicle device 20 confirms the number of times the downloaded information is browsed with reference to the history DB 21 (Step S102), and receives the received information. Is given priority (step S103).

  Then, the in-vehicle device 20 determines to notify the received information unless the user has set a setting such as not to notify the received information (Yes in step S104), and executes an information notification process (step S105). ).

(Flow of information notification processing)
Next, the flow of the information notification process shown in FIG. 7 will be described with reference to FIG. FIG. 8 is a flowchart illustrating a flow of information notification processing in the in-vehicle device according to the first embodiment. As shown in FIG. 8, when the information notification process is started (Yes at Step S201), the in-vehicle device 20 acquires a winker operation signal from the winker sensor 14 (Step S202).

  And if the vehicle-mounted apparatus 20 determines with the blinker not lighting (step S203 negative), it will detect a driver | operator's shift lever operation from the shift lever sensor 15 (step S204).

  Subsequently, when the in-vehicle device 20 determines that the signal received from the shift lever sensor 15 is not a reverse signal, that is, when it is determined that the vehicle is not back (No in step S205), the navigation data is received from the car navigation device 12. Obtain (step S206).

  And when the vehicle-mounted apparatus 20 determines with the acquired navigation data that it is in the state which does not interfere with a driver | operator's driving | operation (step S207 affirmation), driving speed (SPD) and parking brake sensor 16 from the vehicle speed sensor 13 are determined. Parking brake signal (PKB) is acquired from (step S208).

  To give a specific example, the in-vehicle device 20 indicates that the acquired navigation data is “when an intersection, junction, before a railroad crossing, before a toll gate when an ETC (Electronic Toll Collection System) card is not inserted, when an accident occurs frequently, when a lane is decreasing. ", The SPD and the PKB are acquired when it is determined that the state is a state other than the state that needs to concentrate on driving.

  Thereafter, the in-vehicle device 20 determines that the vehicle is traveling, such as when the acquired SPD is greater than 0 km / h and the PKB is OFF (Yes in step S209), and the speakers 17 are sequentially turned on from the information with the highest priority. The driver is notified with the voice via (step S210).

  On the other hand, the in-vehicle device 20 determines that the vehicle is not traveling (stopped), such as when the acquired SPD is 0 km / h and PKB is ON (No in step S209), and information with high priority. The driver is notified in sequence of sound through the speaker 17 and image data (for example, text data) through the display 18 (step S211).

  The in-vehicle device 20 determines that the turn signal is turned on in step S203 (Yes in step S203), and determines that the vehicle is back in step S205 (Yes in step S205), the driver in step S207. When it is determined that the vehicle is in a state that hinders the driving of the vehicle (No at Step S207), the process returns to Step S202 and the subsequent processing is executed.

[Effects of Example 1]
As described above, according to the first embodiment, the in-vehicle device 20 includes the history DB 21 that stores the history viewed by the driver for the information received from the center in the past, receives the information distributed from the center, and stores the information. Priority given to the driver is given to the received information based on the recorded history. And the vehicle-mounted apparatus 20 detects a driving | running state of a vehicle, and notifies a driver | operator in order from the information with a high priority among the information provided with the priority in the format suitable for the detected driving | running state. As a result, it is possible to notify only useful information to the driver while ensuring the driver's safe driving. In addition, the driver and passengers can save the trouble of selecting unnecessary information.

  Further, according to the first embodiment, the in-vehicle device 20 can notify the driver in order from the information with the highest priority when it is determined that the driving is not hindered based on the detected traveling state. As a result, the in-vehicle device 20 can perform safe driving without disturbing the driving of the driver.

  Further, according to the first embodiment, when the detected traveling state is stopped, the in-vehicle device 20 notifies the driver by text data and voice data in order from the information with the highest priority, and is detected. When the running state is running, the driver can be notified by voice data in order from the information with the highest priority. As a result, the in-vehicle device 20 can notify only the driver of useful information without interfering with the driver's driving, and the driver acquires information in a format that can be confirmed while driving. Therefore, it is possible to avoid gaze on the screen and to confirm information while performing safe driving. In addition, since the notification method can be automatically changed at the time of traveling / stopping, the driver and passengers can save the trouble of switching the notification method.

  Further, according to the first embodiment, when the detected traveling state is stopped and the parking brake is OFF, the in-vehicle device 20 informs the driver by text data in order from the information with the highest priority. If the detected running state is stopped and the parking brake is ON, the driver can be notified by text data and image data in descending order of priority. As a result, the in-vehicle device 20 can more accurately determine when the vehicle is stopped and notify the information.

  By the way, in Example 1, although the case where the priority of the information received from the center was given and notified in order was explained, the present invention is not limited to this, and when emergency information is received from the center It is also possible to notify immediately without giving priority.

  Thus, in the second embodiment, an example in which immediate notification is made when emergency information is received from the center will be described with reference to FIG. FIG. 9 is a flowchart illustrating the flow of processing in the in-vehicle device according to the second embodiment.

  As shown in FIG. 9, when the in-vehicle device 20 downloads (DL) information from the center (Yes in step S301), the in-vehicle device 20 determines whether the received information includes emergency information (step S302). Here, as determination of whether or not it is emergency information, for example, it can be determined by analyzing whether or not words such as “emergency information”, “earthquake information”, “typhoon information” are included, It is also possible to analyze and determine whether or not words that are handled as emergency information are included.

  When the received information includes emergency information (Yes at Step S302), the in-vehicle device 20 notifies only the emergency information to the driver by voice or image data (Step S303). Similar to 1, the information notification process is executed by assigning priorities with reference to the history DB 21 (steps S304 to S308).

  When the in-vehicle device 20 notifies the emergency information, if the vehicle is running, the notification is made only by voice, and if the vehicle is stopped, the notification is made by both voice and image data. Good.

  On the other hand, when the urgent information is not included in the received information (No at Step S302), the in-vehicle device 20 refers to the history DB 21 and assigns a priority order to execute the information notification process (No in Step S302) ( Step S306 to Step S308).

  Thus, according to the second embodiment, the in-vehicle device 20 determines whether or not the received information is emergency information having an emergency, and the driver determines the information determined to be emergency information. Immediate notification can be made. As a result, the emergency information can be notified to the driver without delay while ensuring the driver's safe driving.

  Although the embodiments of the present invention have been described so far, the present invention may be implemented in various different forms other than the embodiments described above. Therefore, as shown below, (1) traveling route information, (2) notification method, (3) system configuration, etc., (4) different embodiments will be described by being divided into programs.

(1) Travel route information For example, in the first embodiment, the priority is given to the received information, and then the example in which the priority is given is described in order. However, the present invention is limited to this. Instead, when the information to which the priority is given is information related to the travel route, it can be notified after determining that the driving is not hindered based on the travel state.

  Specifically, the in-vehicle device 20 mounted on the traveling vehicle receives three types of information “weather information, music, and traffic jam information” as information from the center, gives priority, and “music, Suppose that it is decided to notify in the order of “congestion information, weather information”. In this case, the in-vehicle device 20 first notifies “music” by voice because the vehicle is running. Next, the in-vehicle device will notify about “traffic congestion information”, but since the information to be notified is information related to the travel route, it acquires navigation data from the car navigation device 12 and reads “intersection, junction, If it is necessary to concentrate on driving, such as before a railroad crossing, before a toll gate when an ETC (Electronic Toll Collection System) card is not inserted, when there are many accidents, or when the lane is decreasing, it will be in a standby state and will be particularly focused on driving. When it becomes a state other than the state that should be done, “congestion information” is notified by voice. Thereafter, the in-vehicle device 20 notifies “weather information” in the same manner as “music”.

  By doing so, it is possible to notify the driving route (for example, traffic jam information, construction information, accident information, etc.) that the driver will pay the most attention at the timing when it is determined that there is no trouble in driving. It is possible to notify the driver of useful information without disturbing the driving of the driver.

(2) Notification method Further, when the traveling state is stopped, the in-vehicle device 20 disclosed in the present application notifies the driver of all of the information in descending order of priority, and the traveling state is traveling. In such a case, a part of the information can be notified to the driver in order from the information with the highest priority. For example, when the in-vehicle device 20 is stopped, the in-vehicle device 20 notifies all the contents of the mail and information received from the center by voice and displays all the contents of the mail and information on the display 18. When the state is running, it is possible to notify the subject of the mail received from the center and a part of the information by voice.

  By doing so, it is possible to save time for notifying each piece of information, and it is possible to quickly notify the received information. In addition, the driver can ensure privacy such as e-mail.

  The in-vehicle device 20 can also change the notification method depending on whether the parking brake is ON or OFF even when the vehicle is stopped. For example, the in-vehicle device 20 notifies the driver with text data and image data when the vehicle is stopped and the parking brake is ON, and operates only with text data when the vehicle is stopped and the parking brake is OFF. Can also be notified.

  The in-vehicle device 20 can also display a list of received information on the display 18 when the traveling state is stopped. Specifically, as shown in (1) of FIG. 10, the in-vehicle device 20 is configured so that when the vehicle is in a stopped state, regardless of notified information / unnotified information, A list of all received information is displayed on the display 18. And as shown to (2) of FIG. 10, when the driver | operator and a passenger | crew click on the vehicle-mounted apparatus 20, it notifies the said text with a pop-up. FIG. 10 is a diagram illustrating a display example of information.

  The information to be displayed in a list may be only unreported information, and can be arbitrarily set by the user. As for the notification method, not only pop-up but also a ticker can be used.
