Abstract

PROBLEM TO BE SOLVED: To provide a route guidance screen display apparatus for navigation capable of preventing a viewer of an AV apparatus from being annoyed by sudden switching of a display screen to a route guidance screen at a position requiring guide route guidance when a passenger on a front passenger seat or the like is displaying and viewing images of one of various AV apparatuses such as DVD on a monitor for navigation.SOLUTION: When an output image of an AV apparatus is displayed on a monitor capable of displaying guide route guidance images and output images of the AV apparatus, a guide route screen is restrictively displayed in such a manner that only images of the AV apparatus are usually displayed; and when outputting specific guidance such as a right/left turn at an intersection, only voice guidance is outputted, or a right/left turn direction or the like at the intersection is displayed in a simple small window on the screen, or an intersection guidance map is displayed in a small part of the screen given that the screen is divided into large and small parts, or the output image of the AV apparatus is subjected to translucent processing so that it overlaps when displayed on the guide route screen. Provided that a present position is near to a destination and separated from the guide route by a predetermined distance and more, or traveling time is sharply delayed from scheduled traveling time, AV output display is stopped.

Description

  The present invention is a navigation device mounted on a vehicle, and when a passenger such as a passenger seat is viewing a DVD playback or television image on a monitor, the navigation screen is suddenly switched to The present invention relates to a route guidance screen display device for navigation that can prevent temporary interference.

  In recent years, navigation devices are widely used in vehicles, and safe and easy-to-understand guidance is provided from the current location to the destination. In addition, various types of information for guidance can be displayed on a monitor that displays a map or the like for navigation. In particular, at a point where specific guidance is provided, such as a right or left turn intersection on a guidance route, a normal map screen is displayed. Apart from that, the enlarged view of the intersection, the lane to be traveled, the distance to the intersection, etc. are displayed in an easy-to-understand manner on the divided screens. At that time, voice guidance such as “Turn right at the intersection 200 m ahead” is also performed at the same time.

  The monitor of the navigation device as described above can display not only the navigation image but also the output image from, for example, a television receiver. When the vehicle is equipped with a DVD player, the output image is displayed. Is also possible. Furthermore, in recent years, portable AV (Audio Visual) devices equipped with a small hard disk, a large-capacity memory card, and the like have come to be widely used. It is also connected to a head unit having such a navigation function to display an image on a monitor and to listen to sound with an audio device in the vehicle.

  In many cases, the monitor of the navigation device mounted on the vehicle is arranged in front of the driver seat and the passenger seat, and the driver displays the current position of the vehicle on the monitor while driving. The map screen is understood at a glance. However, the driver is obliged to watch forward during normal driving for safe driving, and the Road Traffic Law stipulates that the driver must not "gaze" the screen of the device that displays the image in the car.

  For this reason, vehicle manufacturers set the monitor so that it cannot display images of various AV devices other than the navigation screen on the monitor while the vehicle is running, and performs self-regulation. Yes.

  However, as described above, it is normally only necessary for the driver to “gaze” the monitor screen while driving. Images of various AV devices are output and displayed on the monitor even while the vehicle is moving. That is not illegal. In particular, even a monitor for displaying navigation images that is originally mounted on a vehicle can display images on DVDs and TVs, so the interior of the vehicle is often boring for passengers other than the driver. Depending on the situation, you may want to watch your favorite DVD, or you may want to watch TV such as live coverage of baseball.

  Especially when you have a child in the passenger seat and you are bored and want to show your child's favorite DVD, or when you want to show live baseball on TV, such a DVD. Or turn on the TV. In such a case, the driver can drive safely without paying attention to such a screen.

  Therefore, in general vehicle related parts stores, devices for allowing various AV devices to be seen even while the vehicle is running are widely sold, and they are purchased and attached to the vehicle. Yes. Various devices such as these devices are sold by various companies, and some of them have specific functions, but basically, only a navigation device can be output while the vehicle is running. The function is canceled in the image display function part so that the image of the AV device instructed by the user can be displayed even while traveling.

  In many cases, such an apparatus displays the image of the AV apparatus instructed by the user in preference to the navigation screen even during the operation of the navigation. Since guidance is not output, problems such as going straight at intersections that must originally turn left and right often occur. Therefore, as a countermeasure, when driving on a guidance route with the navigation function, navigation is performed from the display screen of the AV device in a specific guidance output state that requires guidance to the driver, such as a right-left turn intersection as described above. Many devices are trying to switch to the route guidance screen.

  Japanese Patent Application Laid-Open No. 2004-151867 discloses a navigation device that automatically resumes route guidance when it is estimated that the vehicle is lost after the route guidance is completed.

JP 2006-58025 A

  As described above, images of various AV (Audio Visual) devices mounted on the vehicle or brought into the vehicle even when the vehicle is running are displayed in place of the navigation screen running along the guidance route. When it is judged that important information should be provided to the driver by approaching a right or left turn intersection by the navigation function, switching from the output screen of the AV device to the navigation route guidance screen is performed. In such cases, the following problems may occur.

  That is, for example, when a child sits in the passenger seat, gets bored in the car for a long time, and gradually gets sick, play it back on the child's favorite Mobile Suit DVD. However, instead of the navigation route guidance screen display, for example, when a DVD image as shown in FIG. 8A is shown, a specific guidance such as a right-left turn intersection important for the navigation function as described above is given. When the point to be performed is reached, as shown in FIG. 5C, the navigation system is switched to the right / left turn intersection guidance for normal navigation and the screen for displaying the surrounding map. At that time, when the child who was quietly watching his favorite DVD was most excited, the DVD screen suddenly disappeared and became a map screen, which could make a fuss.

  Similarly, for example, as shown in FIG. 8B, when a high school baseball broadcast on TV is shown for a child in the passenger seat, a specific guidance such as a right / left turn intersection important for the navigation function as described above is given. When the point to be performed is reached, as shown in FIG. 5C, the navigation system is switched to the right / left turn intersection guidance for normal navigation and the screen for displaying the surrounding map. Even at this time, even when the current ball is a big turning point of the game, and when the screen is switched to the map screen, children and the like may make a fuss.

  Therefore, the present invention provides a navigation system such as a right-left turn intersection when a passenger such as a passenger seat switches and displays images of various AV devices on a monitor displaying a map screen or the like for navigation. By switching to the navigation map screen at a specific point where it is preferable to provide guidance for navigation, navigation that allows simple guidance while preventing troubles for viewers of AV equipment as much as possible The main purpose is to provide a route guidance screen display device.

  In addition, when it is estimated that navigation by a driver is particularly necessary in an apparatus equipped with such a device, guidance for a guidance route is performed on a normal full screen without providing guidance for a simple guidance route. The purpose is also to be able to.

  In order to solve the above problems, a navigation route guidance screen display device according to the present invention displays a guidance route calculation means for calculating a guidance route to a destination, and a guidance image of the guidance route calculated by the guidance route calculation means. And a monitor for displaying an output image of the AV device, and an AV output priority instruction means for restricting the output of the guidance image of the guidance route when the output image of the AV device is displayed on the monitor, The AV output priority instructing means stops outputting the guidance image of the guidance route at times other than the specific guidance output of the guidance route, and adds a predetermined restriction to the guidance output of the guidance route at the specific guidance output of the guidance route. It is characterized by giving an instruction to guide.

  In another navigation route guidance screen display device according to the present invention, in the navigation route guidance screen display device, the specific restriction performed by the AV output priority instruction means is to output a guidance image to a guidance route monitor. Is stopped, and only voice guidance is performed.

  In another navigation route guidance screen display device according to the present invention, the predetermined restriction performed by the AV output priority instructing means in the navigation route guidance screen display device is that of the monitor displaying the AV output image. The navigation route guidance screen display device according to claim 1, wherein a simple small screen is formed in the screen, and guidance display is performed in the simple small screen.

  In another navigation route guidance screen display device according to the present invention, in the navigation route guidance screen display device, the predetermined restriction performed by the AV output priority instructing means divides the monitor screen by distinguishing the size. The guidance route guidance screen is output on a small divided screen, and the output image of the AV device is displayed on the large divided screen.

  Further, in another navigation route guidance screen display device according to the present invention, in the navigation route guidance screen display device, the predetermined restriction performed by the AV output priority instructing means is to make the AV image translucent, It is characterized by being displayed over the screen.

  In another navigation route guidance screen display device according to the present invention, in the navigation route guidance screen display device, whether the AV output is stopped and a specific condition for displaying a guidance route on a full screen is met. AV output stop determining means for determining whether the AV output is stopped by the AV output stop determining means, and a guide route screen is displayed on the entire screen of the monitor.

  In another navigation route guidance screen display device according to the present invention, in the navigation route guidance screen display device, the specific condition is that the guidance route deviates a predetermined distance or more. To do.

 In another navigation route guidance screen display device according to the present invention, in the navigation route guidance screen display device, the specific condition is a time required for traveling on a guidance route obtained from map data. On the other hand, it is characterized in that the time from the actual start of traveling is a delay time delayed by a predetermined time or more.

  Further, in another navigation route guidance screen display device according to the present invention, in the navigation route guidance screen display device, the specific condition includes being within a predetermined distance from a destination. .

  Since the present invention is configured as described above, when a passenger such as a passenger seat is switching and displaying images of various AV devices on a monitor that displays a map screen or the like for navigation, it turns right and left. By switching to the navigation map screen at a point where specific guidance for navigation such as intersection guidance is performed, simple guidance of the guidance route is provided while preventing inconvenience to viewers of AV equipment as much as possible. Will be able to.

It is. It is a figure which shows an example of AV output priority mode setting screen. It is a figure which shows the example of a confirmation screen display when displaying guidance route guidance on a full screen during AV output image display. It is a figure which shows the state which came to display guidance route guidance on a full screen in the specific guidance output point during the conventional AV output screen display.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an example in which the present invention can be implemented in various modes. Therefore, the present invention can be implemented in various modes by selecting any one of these functional blocks. In addition, the function part which performs each function in the figure can also be said to be a means which performs each function.

  FIG. 1 shows various functional units of a conventional navigation apparatus, functional units that operate in the present invention, and AV output device related functional units that output to a monitor 20. In the example of FIG. 1, in order to function as a navigation device and to perform operations related to image output and audio output operations of AV equipment in connection with the navigation function, a ROM storing a program and those programs are stored. Each functional unit is connected to a system control unit 10 including a CPU that performs arithmetic processing and the like for execution, and a RAM that stores temporary data during various arithmetic processing and the like, so that predetermined operations can be performed.

  In the illustrated navigation apparatus, a vehicle position detection unit 13 is connected to the system control unit 10 and the position data of the GPS receiver 11 is input. By inputting the movement data of the vehicle from the azimuth detecting unit 12, the current position of the vehicle is accurately detected. Further, the VICS information input unit 14 can receive FM radio waves, beacons, etc., capture traffic information, and particularly input traffic jam information.

  In the instruction signal input unit 17, various instruction signals can be input by the remote controller 15 or by recognizing a voice as a user instruction signal, and further by a touch panel operation of the monitor 20. The data fetching unit 19 fetches necessary map data, facility information, etc. from a map / information data recording medium 18 such as a DVD-ROM or a hard disk or a memory card, and the data recording medium is like a hard disk or a memory card. When data can be written easily, data can be recorded on the data recording medium so that data taken from outside or data processed by other functional units can be read and used. .

  The image output unit 21 outputs various images that the navigation device guides to the user to the monitor 20. In addition, when the device performing the navigation function is a head unit, for example, the head unit itself or It is connected to a DVD player or a television receiver mounted on the vehicle, and these images can be switched to a navigation route guidance screen for display. The audio output unit 23 outputs various types of guidance such as guidance route guidance and the audio of the AV device as described above from the speaker 22.

  In the guidance route calculation unit 24, the current position of the vehicle detected by the vehicle position detection unit 13 is captured, and the map is scrolled by operating the cursor displayed on the screen or the touch panel, or by inputting an address. Takes in the waypoints and final destinations set by various methods such as entering a telephone number, and calculates and presents the optimum guidance route under various conditions such as the shortest required time, shortest distance, and general road priority . The guide route storage unit 25 stores the guide route selected and instructed by the user for the guide route calculated and presented by the guide route calculation unit 24.

  The guidance route guidance processing unit 26 performs guidance corresponding to the current position detected by the vehicle position detection unit 13 for the guidance route stored in the guidance route storage unit 25, and the specific guidance route guidance position approach detection unit 33 Detecting that the vehicle has approached a predetermined right or left turn intersection or the like within a predetermined distance. Further, when the guide route guidance information forming unit 34 detects that the specific guide route guide position approach detecting unit 33 has approached the guide position within a predetermined distance as described above, the situation specific to the point is taken into consideration, Form information to be guided. These are the same as the navigation function unit conventionally used.

  In the AV output priority mode setting unit 27, when performing AV output of various devices such as the AV output device 51 in FIG. Set various modes when outputting with priority over guidance output by image. At that time, for example, the setting can be performed as shown in FIG.

  In the example of the AV output priority mode setting screen shown in FIG. 6, “playback priority” is selected from various settings on the initial setting screen of the navigation function, as shown in FIG. This function can be used by selecting “Yes” with. In the example of FIG. 6, when “Yes” is selected in “Playback priority”, a screen for performing the detailed setting as shown in FIG. 6B is displayed, in which “Voice guidance only” “Simple small screen” In this example, the items “display”, “intersection guidance display only”, and “AV image translucent processing” are selectable. In the example shown in the figure, “simple small screen display” is selected, and “Yes” is selected for this.

  An example of the setting as described above is also shown in FIG. 1, and when “guide only with guidance route voice” 28 in the AV output priority mode setting unit 27 is selected, an image of the AV device is output to the monitor 20 and displayed. When a specific guidance such as a right or left turn intersection is made, the guidance route is guided only by voice. This state wave diagram is shown in FIG. On the other hand, when “intersection guidance display on simple small screen” 29 is selected, for example, as shown in FIG. To display the direction of turning left and right, the distance to the intersection, and the like.

  Further, when the “intersection guidance display in divided screen” 30 is selected, for example, as shown in FIG. 5A, the screen is divided into two parts with a size distinction, and the smaller divided screen on the driver side is the minimum. The size is large enough to guide the intersection, and an enlarged guidance display of the intersection is displayed as shown in FIG. In the example shown in the figure, an example is shown in which the entire large screen is displayed by reducing the DVD screen accordingly. However, when the intersection guide display may be sufficiently small, the same figure may be displayed so as to overlap a part of a normal DVD image.

  Further, when “AV image translucent processing” 31 is selected, for example, a DVD image as shown in FIG. 4A is translucent and superimposed on the navigation intersection guidance screen as shown in FIG. 8C. To display. In addition, the navigation guidance screen may be translucently processed and displayed on the AV output screen. Furthermore, the transparency may be arbitrarily set, and the setting may be possible in various modes, such as displaying the side that is considered important for display darkly.

  As will be described later, the confirmation display output unit 32 needs to stop the AV output even when the AV output stop determination unit 42 performs a function of displaying the image of the AV device in preference to the navigation guidance screen. When it is determined that there is an error, various confirmation displays such as a confirmation display as to whether or not the AV output can be actually stopped can be performed.

  In the AV output priority guidance instruction unit 35, as will be described later, any one of the AV output devices 51 is selected and operated, an image is displayed on the monitor, and sound is output from the speaker. In the illustrated example, the AV output control unit 54 captures the signal of the AV output control unit 54. Further, the AV output priority mode selection fetching unit 37 captures which mode is selected by the AV output priority mode setting unit 27. This instructs the guidance route guidance screen display processing unit 38 how to display the navigation guidance route guidance screen.

  The guidance route guidance screen display processing unit 38 forms a navigation guidance screen according to the instruction of the AV output priority instruction unit 35 as described above, and also guides according to the determination of the AV output stop determination unit 42 described later. Processing is performed using the guidance information formed by the route guidance information forming unit 35. Among them, the full-screen guidance route guide map display 39 displays a navigation guide map similar to the state in which there is no output from the AV device. In particular, the AV output stop determination unit 42 provides guidance with priority on AV output. The driver may be at a loss when he / she is driving, for example, when he / she is close to his / her destination but greatly deviates from the guidance route or when he / she is far behind the initial scheduled time. Therefore, it is determined that the AV output priority guidance is not in a state, and thereafter, the guidance route guidance is always displayed on the entire screen.

  In the in-division screen intersection guide display 40, an enlarged guide map of the intersection is displayed on the divided screen as shown in FIG. In the simple small screen display 41, as shown in FIG. 4B, a simple left / right turn guide map of an intersection of the small screen is displayed at a position that is easy for the driver to see.

  As described above, in the AV output stop determination unit 42, even when guidance is given with priority on AV output, when it is largely deviated from the guidance route despite being close to the destination, it is delayed significantly from the initial scheduled time. In such a case, it is assumed that the driver is likely to be at a loss, and an operation for determining that the AV output priority guidance is not in effect is performed.

  In the destination within predetermined distance detection unit 43, the position of the vehicle detected by the vehicle position detection unit 13 is within a predetermined distance such as 5 km to the destination stored in the guidance route storage unit 25, Alternatively, it is detected that the distance is within a predetermined distance L1, such as a distance within 10% of the entire stroke. The guide route departure distance calculation unit 44 calculates the distance at which the current position deviates from the guide route. In the departure distance availability determination unit 45, it is determined whether or not the departure distance calculated by the guidance route departure distance calculation unit 44 deviates by a predetermined distance L2 or more, for example, 1.5 km or more, or 30% or more of the predetermined distance L1. Determine. Accordingly, it is determined that the driver is currently driving greatly deviating from the original road and is likely to be lost.

  The travel delay time calculating unit 46 travels the guide route from the destination to the current vehicle position calculated for the guide route stored in the guide route storage unit 25 based on data such as the road link travel cost. The travel prediction time T1 required for the travel is calculated, and a delay time T3 (= T2-T1) is calculated as to how much the travel time T2 after the start of travel is delayed from the travel prediction time T1.

  In the delay time availability determination unit 47, the delay time calculated by the travel delay time calculation unit 46 as described above is, for example, 1 hour or more, or the travel time predicted to be necessary when traveling from the departure place to the current position on the guidance route. It is determined whether or not the reference delay time is 30% or more. Due to the above processing, the current time is far behind the expected time at departure, so it is determined that it is necessary to drive reliably according to the guidance of the navigation from now on, or it is currently scheduled due to getting lost Since it is far behind the time, it is determined that it is preferable to travel reliably in accordance with navigation guidance.

  As described above, the AV stop determination unit 42 in FIG. 1 operates considerably when the vehicle is approaching the destination within a predetermined distance, when it is determined that the vehicle has deviated more than the predetermined distance from the guidance route, When it is determined that there is a delay, only voice guidance is provided with the AV output priority guidance as described above, or guidance in the direction of left or right turn is provided on a simple small screen, and further, an enlarged guidance display of the intersection is displayed on a divided screen. In addition, even when processing for displaying the AV screen with transparency processing is performed, in any case as described above, the AV output is stopped and guidance display is performed on the entire screen. Can be.

  In addition to the above, when it is determined that the vehicle has deviated from the guidance route by a predetermined distance or more as described above and when it is determined that the vehicle is considerably behind the scheduled time, the guidance route guidance output is performed. In addition to the above, after detecting that the state is in any one of the above cases, the AV output is always performed in addition to the specific guidance output in order to ensure that the vehicle travels along the guidance route. Can also be set to stop completely.

  Furthermore, in the above example, the example in which the AV output stop processing as described above is performed when approaching the destination by a predetermined distance or more is shown. When it is determined that the destination is not yet within the predetermined distance. However, when the deviation distance is further larger, or when the delay time is further longer, the AV output can be stopped in the same manner as described above.

  The guidance route guidance output unit 48 outputs the image and sound processed by the guidance route guidance processing unit 26 as described above, and the image output unit 49 performs normal processing when the image of the AV device is not output. In the state of performing specific guidance route guidance when the image output of the AV device is being performed, if AV output priority is set, the guidance route image is output according to the selected mode. I do. The voice output unit 50 always performs guidance output of the guidance route in principle.

  In the example of FIG. 1, as an example of outputting images of various AV devices 51 to a monitor 20 that normally displays a navigation guidance screen, a DVD player 52, a memory card 53 that compresses and records AV data, a television receiver An example of the vessel 54 is shown. However, it is also possible to connect devices such as multi-function mobile phones and portable information terminals that record AV data or can output AV data taken in from an AV data download site.

  The AV output control unit 55 takes in the image and audio signals from the various AV output devices 51 as described above, and performs various AV output controls in connection with the operation of the various function units of the guidance route guidance processing unit 26. Do. At that time, the output ON / OFF control unit 56 stops the output of the AV image according to the determination result of the AV output stop determination unit 42 particularly for the output image. The screen size adjustment unit 57 adjusts the size so that the AV image fits in the remaining divided screen when the intersection guidance of the guidance route guidance is displayed on the divided screen as shown in FIG. 5A, for example. .

  In the translucent adjustment unit 58, when the AV output priority mode setting unit 27 is selected and set to perform the AV image translucency processing 31 as described above, the AV output priority instruction unit 35 is instructed to perform the AV output. Translucent processing is performed on the image. When the image is output from the AV image output unit 61 of the AV output unit 60 to the monitor 20, it is displayed so that both images can be seen together with the image of the guidance route guidance output unit 49. The process of superimposing both screens at this time is performed by the image output unit 21.

  In the sound volume adjustment unit 59, as for the audio output of the AV equipment, for example, in a state where specific guidance of the guidance route is performed, in principle, the guidance sound is always output, and it is important for the driver to receive guidance without looking at the monitor. Therefore, for example, adjustments such as lowering the volume are performed so as not to be erased by the sound of the DVD or television.

  In the AV output unit 60, the image adjusted by the AV output control unit 55 as described above is output from the image output unit 61 and displayed on the monitor 20. Similarly, the sound adjusted appropriately is output from the audio output unit 62. And output from the speaker 22 into the vehicle. As for AV output sound, for example, when an earphone output unit exists in a head unit or the like, when an earphone or headphone is connected to the earphone jack, only AV sound may be set to be switched to the earphone or the like. good.

  In this invention which consists of the above functional blocks, it can implement by operating in order according to the operation | movement flow of FIG. 2, for example. FIG. 2 shows an example of guidance route guidance processing. First, it is determined whether or not the vehicle is traveling with a guidance route set (step S1). When it is determined that the guide route is not set, the process proceeds to step S8 to determine whether or not the destination has been reached. When it is determined that the destination has not yet been reached, the process returns to step S1 again. After that, it is confirmed whether the guide route has been set, and when the vehicle arrives at the destination in such a state, the operation flow is terminated (step S9).

  When it is determined in step S1 that the guidance route is set and the vehicle is traveling, it is determined whether an image of the AV device is output to the monitor (step S2). When it is determined that the image output of the AV device is not performed, the process proceeds to step S7, where guidance on the guidance route is displayed on the entire screen and voice guidance is output. Thereafter, the process proceeds to step S8, where it is determined whether or not the destination has been reached in the same manner as described above. When it is determined that the destination has not yet been reached, the procedure returns to step S1 to cancel or change the set guide route. To check.

  When it is determined in step S2 that an image of the AV device is being output to the monitor, an AV output stop determination process around the destination as shown in FIG. 3 is performed (step S3). That is, in the example of the AV output stop determination process in the vicinity of the destination shown in FIG. 3, the current position is determined as the process after determining that the image of the AV device is being output to the monitor in step S2 in FIG. It is determined whether or not the vehicle is around the destination (step S11). This processing is performed by the destination predetermined distance detection unit 43 in the AV output stop determination unit 42 of FIG. 1 as described above.

  When it is determined in step S11 that the current position is around the destination, it is determined whether or not the AV output priority mode is set (step S12). Here, as described above, it is determined that the setting is not made to perform the AV output priority mode so that the AV image being output is suddenly switched to the navigation guidance screen and the AV image is not seen. To proceed, the process proceeds to step S21, and it is determined whether or not a specific guidance output state such as a right / left turn intersection has been reached.

  When it is determined in step S21 that the specific guidance output state has not yet been reached, the process returns to step S12, and thereafter it is checked whether the AV priority mode has been set, and the above operation is repeated. When it is determined in step S21 that the specific guidance output state has been reached, the process proceeds to step S19, where guidance on the guidance route is displayed on the entire screen and voice guidance is output in step S7 of FIG.

  When it is determined in step S12 in FIG. 3 that the AV output priority mode is set, the deviation distance from the guide route is calculated in the example in FIG. 3 (step S13). Next, it is determined whether or not the departure distance is greater than a predetermined distance (step S14). If it is determined that the departure distance is not greater than the predetermined distance, a delay time with respect to the expected arrival time is calculated (step S15).

  Thereafter, it is determined whether or not the delay time is greater than a predetermined time (step S16). When it is determined that the delay time is greater than the predetermined time, a confirmation message as to whether or not to interrupt the AV output is displayed in step S17. In this case, for example, the example shown in FIG. 7 shows an example in which a message “Do you want to switch to the detailed map” and a selection screen of “Yes” and “No” are displayed during the output display of the AV image. Yes. In this display, the confirmation screen may be translucently processed.

  Next, it is determined whether or not AV output interruption has been selected (step S18). When "Yes" is selected on the message display screen as described above, the process proceeds to step S7 in FIG. Displays guidance and provides voice guidance. As a result, even when the AV output priority mode is set, the driver can determine that he is currently lost or is far behind the schedule, and can concentrate on driving while paying attention to the navigation guidance. To do. These processes are performed as described above in each functional unit of the AV output stop determination unit 42 of FIG.

  On the other hand, when it is determined in step S11 that the current position is not around the destination, and in step S16 that is performed as a process after determining that the departure distance is not greater than the predetermined distance in step S14, the delay time is When it is determined that the time is not longer than the predetermined time, the process proceeds to step S4 in FIG. 2 in step S20.

  In the example shown in FIG. 3, when it is determined in step S12 that the AV output priority mode is set, the departure distance is always greater than or equal to a predetermined distance regardless of whether or not the specific guidance output state is set. If there is a delay time greater than the specified time, an example is shown in which the guidance screen of the guidance route is always displayed on the full screen after displaying the confirmation message maintenance, but only when the navigation guidance is in a specific guidance output state The process may proceed to step S7 in FIG. 2 to display guidance route guidance on the entire screen.

  When step S20 in FIG. 3 proceeds to step S4 in FIG. 2, it is determined whether or not a specific guidance output state has been reached as shown in FIG. When it is determined, it is determined whether or not the AV output priority mode is set (step S5). When it is determined that the AV output priority mode is set, the AV output priority mode set in advance at step S6 is activated.
