Description

  The present invention relates to a navigation apparatus that is mounted on a vehicle and guides the vehicle to a destination.

  Many of the navigation devices mounted on the vehicle are overlapped on the displayed map screen and other screens (for example, AV operation screen) when the vehicle approaches a right-left turn intersection while driving with a guidance route set. The intersection guide map for guiding the right / left turn direction of the vehicle is displayed.

  Conventionally, when road traffic information transmitted from the VICS (registered trademark) center is received while the vehicle is running, the information is not displayed indefinitely, but is displayed according to the type of road being traveled. A navigation device that can set a display duration and the like is known (for example, see Patent Document 1).

JP 2006-105697 A

  By the way, when the intersection guide map is displayed when approaching the right or left turn intersection as in the above-described navigation device, for example, when the AV screen is being displayed, the intersection guide map is displayed over the AV screen. The visibility of the displayed content deteriorates. In particular, when the vehicle is parked waiting for a signal at a right or left turn intersection, it is considered that no problem will occur even if the display is turned off. However, if the display of the intersection guide map is to be erased before passing through the intersection, there is a problem that a special operation for that purpose is required and the operation becomes complicated.

  On the other hand, when the method used in the navigation device disclosed in Patent Document 1 described above is used, information once started to be displayed can be erased without performing a special operation after a predetermined time has elapsed. By applying an intersection guide map as this information, the intersection guide map displayed before entering the intersection can be erased without any special operation after a predetermined time has elapsed. The display of the intersection guide map can also be turned off. However, the time it takes for the vehicle to reach the intersection after starting the display of the intersection guide map and the time until it actually passes through the intersection vary depending on the speed of the vehicle, the degree of congestion and traffic jams, etc. If the display time of the guide map is set, the driver cannot fully recognize the contents of the intersection guide map, and it is not appropriate to apply the method of Patent Document 1 to the display of the intersection guide map. . For example, if the road is congested at the time of starting the display of the intersection guide map, if this display is turned off after a predetermined time has passed, whether or not the vehicle will turn right or left at this intersection when it actually approaches the intersection Or, when making a right or left turn, it may be difficult to know which direction to turn left or right.

  The present invention was created in view of the above points, and an object of the present invention is to provide a navigation device that can turn off the display of intersection guidance information without performing a special operation.

  In order to solve the above-described problem, the navigation device according to the present invention detects a guide information display timing corresponding to an intersection existing in front of the host vehicle while traveling along a predetermined travel route. An intersection guidance information display means for displaying guidance information about the intersection on the display device at a timing detected by the detection means and the guidance information display timing detection means; and before the host vehicle reaches the intersection, Display interruption means for interrupting display of the guidance information by the intersection guidance information display means when the state satisfies a predetermined display interruption condition;

  When the approaching intersection is met, when the display interruption condition is met, the display of the guidance information that has been performed until then is interrupted, so the guidance information can be erased without performing any special operation. It can prevent becoming complicated.

  Moreover, it is preferable that the intersection that is the detection target of the display timing by the above-described guidance information display timing detection means is a right-left turn intersection where the host vehicle turns right or left along a preset travel route. As a result, even when guidance information necessary for guidance for turning left and right is displayed, the display can be surely turned off without performing a special operation.

  The display interruption condition described above is preferably when the host vehicle stops or when the traveling speed of the vehicle becomes a predetermined value or less. Alternatively, the display interruption condition described above is desirably when the state where the host vehicle is stopped continues for a predetermined time, or when the state where the traveling speed of the vehicle is equal to or less than a predetermined value continues for a predetermined time. In these cases, even if the display of the guidance information is turned off, it is considered that there is almost no influence on the vehicle travel guidance. Therefore, the display device can display other images by turning off the display of such unnecessary guidance information. It becomes possible to use for.

  Further, it is desirable that the display interruption means described above resumes the display of the guidance information by the intersection guidance information display means when the traveling state of the host vehicle no longer satisfies the display interruption condition. By displaying the guidance information again, for example, when the traveling of the vehicle stopped before reaching the intersection is resumed, the traveling guidance of the vehicle at the intersection reaching thereafter can be reliably performed.

  In addition, a plurality of the display timings described above exist for one intersection, and when the intersection guidance information display means has stopped displaying the guidance information by the display interruption means before reaching the second and subsequent display timings, It is desirable to display the guidance information again at the second and subsequent display timings. By preparing multiple display timings of guidance information before reaching the intersection, the guidance information once disappeared can be displayed again, and the vehicle traveling guidance at the intersection that arrives after that can be reliably performed Can do.

  Further, the display of the guidance information described above is performed on the map image or other image displayed on the display device so as to be superimposed or arranged, and the display interruption of the guidance information by the display interruption means is superimposed on the other image or It is desirable to be performed in a state where guidance information is displayed side by side. Specifically, the other image described above is desirably an AV screen image related to reproduction of at least one of audio and video. Accordingly, even when an image other than a map image (for example, an image on an AV screen) is displayed and guidance information is displayed superimposed or arranged on this image, the display can be appropriately deleted. It is possible to increase the chance of viewing images other than.

Note that music data is taken into the hard disk device 70 by a method of reading (ripping) from a CD or DVD using a disk reading device (not shown), or receiving from a music distribution server (for example, a USB interface). A portable terminal device connected to a unit (not shown), a method of transferring music data recorded in a USB memory, and the like may be considered. However, other methods may be used.

  The TV tuner processing unit 16 receives a broadcast signal such as terrestrial digital broadcast and performs processing for reproducing video and audio. The radio tuner processing unit 18 receives a broadcast signal of AM radio broadcast or FM radio broadcast and performs a process of reproducing sound.

  The operation unit 20 is for receiving instructions and operations by the user for the in-vehicle device 1 and includes various operation keys, operation switches, operation knobs, and the like arranged around the display device 32. . Further, when various operation screens and input screens are displayed on the display device 32, the user directly points a part of these operation screens and input screens with a finger or the like, so that display items of the operation screens and input screens are displayed. A touch panel that detects the position of the finger pointed to is a part of the operation unit 20 in order to enable operations using such operation screens and input screens. As provided. Instead of using the touch panel, a part of the operation screen or the input screen may be selected according to a user instruction using a remote control unit or the like. The input control unit 22 monitors the operation unit 20 and determines the operation content.

  The display processing unit 30 outputs video signals for displaying various operation screens, input screens, etc. and displays these screens on the display device 32, and video reproduced by the AV processing unit 14, the TV tuner processing unit 16, and the like. A video signal for displaying a screen, an operation screen, or the like is output and displayed on the display device 32. The display device 32 is installed in front of the center of the driver seat and the passenger seat, and is configured using, for example, a liquid crystal display device (LCD).

  The digital-analog converter 40 converts audio data generated by each of the navigation processing unit 10, the AV processing unit 14, the TV tuner processing unit 16, and the radio tuner processing unit 18 into an analog audio signal and converts the audio data into a speaker 42. Output from. In practice, an amplifier for amplifying a signal is connected between the digital-analog converter 40 and the speaker 42, but this amplifier is omitted in FIG. Further, the combination of the digital-analog converter 40 and the speaker 42 is provided for the number of reproduction channels, but only one set is shown in FIG.

  The control part 50 is for controlling the whole vehicle-mounted apparatus 1, and is implement | achieved by running the predetermined program stored in ROM, RAM, etc. by CPU.

A tuner control unit 54 is included.

  Next, the configuration of the navigation processing unit 10 will be described. FIG. 2 is a diagram illustrating a configuration of the navigation processing unit 10. As shown in FIG. 2, the navigation processing unit 10 includes a map buffer 100, a map readout control unit 102, a map drawing unit 104, a vehicle position calculation unit 110, a route search processing unit 120, a route guidance processing unit 122, and a destination setting unit. 124, a guidance timing detection unit 130, and a display interruption determination unit 132.

  The map buffer 100 temporarily stores map data read from the hard disk device 70. The map reading control unit 102 outputs a request for reading a predetermined range of map data to the hard disk device 70 in accordance with the vehicle position calculated by the vehicle position calculating unit 110 and an instruction from the input control unit 22. Based on the map data stored in the map buffer 100, the map drawing unit 104 performs drawing processing necessary to display a map image and creates map image drawing data.

  The vehicle position calculation unit 110 calculates the vehicle position based on the detection data output from the GPS device 12, and corrects the vehicle position when the calculated vehicle position is not on the road of the map data. Perform map matching processing.

  The route search processing unit 120 obtains a travel route (guidance route) connecting the departure point and the destination (or waypoint) according to a predetermined search condition by route search processing. The route guidance processing unit 122 guides route guidance data for displaying the guidance route obtained by the route search processing by the route search processing unit 120 on the map, and guidance information for guiding the right / left turn direction at the right / left turn intersection. The intersection guidance drawing data for displaying the enlarged view of the intersection (intersection guide map) is created, and the guidance voice signal necessary for guiding the vehicle traveling by voice along the guidance route is generated and output. . The destination setting unit 124 sets a destination or waypoint for the route search process. For example, the destination setting unit 124 searches for a facility that satisfies the search condition specified by the user and sets it as the destination.

  The guidance timing detection unit 130 detects the display timing of an intersection guide map corresponding to an intersection existing ahead (a right-left turn intersection) while the host vehicle is traveling along the guidance route. For example, in the present embodiment, a time point that passes a point that is 200 m away from a right / left turn intersection is detected as the first guidance timing, and a time point that passes a point that is 50 m ahead is detected as the second guidance timing. .

  The display interruption determination unit 132 determines whether or not the traveling state of the host vehicle satisfies a predetermined display interruption condition before the host vehicle reaches the right / left turn intersection, and determines that the vehicle has been satisfied. The route guidance processing unit 122 is instructed to interrupt the display of the intersection guide map. The display interruption condition may be when the host vehicle stops or when the vehicle travels at a low speed of a predetermined value (for example, 10 km) or less. In addition, you may make it determine with satisfy | filling display interruption conditions, when these states (stop or low-speed driving | running | working below predetermined) continue for the predetermined time.

  In addition, the display interruption determination unit 132 determines whether or not the traveling state of the host vehicle does not satisfy the display interruption condition described above, and determines that the vehicle does not satisfy the above-described display interruption condition. An instruction to resume the display of the guide map is given.

  The above-described guidance timing detection unit corresponds to the guidance information display timing detection unit, the route guidance processing unit 122 corresponds to the intersection guidance information display unit, and the display interruption determination unit 132 corresponds to the display interruption unit.

  The in-vehicle device according to the present embodiment has such a configuration. Next, an operation for displaying an intersection guide map when a right / left turn intersection is reached during route guidance will be described. During route guidance, in addition to the display of the intersection guide map, the guidance route is displayed superimposed on the map, or the vehicle is guided along the guidance route by voice. Let us focus on the display operation of the intersection guide map.

  FIG. 3 is a flowchart showing an operation procedure for displaying an intersection guide map before reaching an intersection that turns right or left during route guidance.

  The guidance timing detection unit 130 determines whether or not the route guidance processing unit 122 is performing route guidance (step 100). If the route is not being guided, a negative determination is made and this determination is repeated. If the route is being guided, an affirmative determination is made in step 100. Next, the guidance timing detection unit 130 determines whether or not the first guidance timing (first guidance timing 200 m before the right / left turn intersection) has arrived (step 102). If it has not arrived, a negative determination is made, and the process returns to step 100 to repeat the determination of whether the route is being guided.

  Further, when the traveling position of the vehicle moves forward and reaches a location corresponding to the first guidance timing, an affirmative determination is made in the determination of step 102. Next, the route guidance processing unit 122 starts displaying the intersection guide map (step 104). For example, as shown in FIG. 4 (A), the area around the right half of the display screen as shown in FIG. 4 (B) from the state in which the map around the host vehicle is displayed using the entire display screen of the display device 32. It shifts to the state where the intersection guide map is displayed. When this intersection guide map is displayed, the surrounding map is displayed using the remaining left half area, but the intersection map is displayed in the right half area without changing the display state of the surrounding map. You may make it overlap.

  Next, the display interruption determination unit 132 determines whether or not the traveling state of the vehicle satisfies a predetermined display interruption condition (stopping or low-speed traveling) before the host vehicle reaches the right / left turn intersection (step 106). ). If the display interruption condition is not satisfied, a negative determination is made. Next, the route guidance processing unit 122 determines whether or not the vehicle has passed a right / left turn intersection (step 108). If it has not passed, a negative determination is made, and the process returns to step 104 to continue the display of the intersection guide map. If a right / left turn intersection is added, an affirmative determination is made in step 108. In this case, the route guidance processing unit 122 ends the display of the intersection guide map (step 110). Thereafter, the process returns to step 100 and the determination of whether or not the route is being guided is repeated.

  If the display interruption condition is satisfied, an affirmative determination is made in step 106. Next, the display interruption determination unit 132 instructs the route guidance processing unit 122 to interrupt the display of the intersection guide map (step 112). In response to this instruction, the route guidance processing unit 122 interrupts the display operation of the intersection guide map. Thereby, for example, the display shown in FIG. 4B is returned to the display shown in FIG.

  Thereafter, the display interruption determination unit 132 determines whether or not the traveling state of the host vehicle does not satisfy the display interruption condition described above (step 114). A negative determination is made when the running state that satisfies the display interruption condition continues. Next, the guidance timing detection unit 130 determines whether or not the next guidance timing (second guidance timing 50 m before the right / left turn intersection) has arrived (step 116). If it has not arrived, a negative determination is made, and the process returns to step 112 to continue the display of the intersection guide map.

  Further, when the display interruption condition is not satisfied (affirmative determination in the determination of step 114), or when the traveling position of the vehicle moves forward and reaches a position corresponding to the second guidance timing (affirmative determination in the determination of step 116). ), The route guidance processing unit 122 resumes displaying the interrupted intersection guide map (step 118). The display interruption determination unit 132 determines that the display interruption condition is not satisfied, and notifies the route guidance processing unit 122 to that effect. On the other hand, the guidance timing detection unit 130 determines that the vehicle has arrived at a location corresponding to the second guidance timing, and notifies the route guidance processing unit 122 to that effect. After the display of the intersection guide map is resumed, the process returns to step 104 and the display of the intersection guide map is continued.

  As described above, in the navigation processing unit 10 of the in-vehicle apparatus 1 of the present embodiment, when the display intersection condition is satisfied when the passing intersection is reached, the display of the intersection guide map that has been performed is interrupted. Therefore, the intersection guide map can be erased without performing a special operation, and the operation can be prevented from becoming complicated.

  In particular, when the intersection guide map is displayed and the display is interrupted for the right-left turn intersection where the vehicle turns right or left along the preset driving route, and the intersection guide map necessary for right-left turn guidance is displayed. Even if it exists, the display can be surely turned off without performing a special operation.

  The display interruption condition described above is preferably when the host vehicle stops or when the traveling speed of the vehicle becomes a predetermined value or less. Alternatively, the display interruption condition described above is desirably when the state where the host vehicle is stopped continues for a predetermined time, or when the state where the traveling speed of the vehicle is equal to or less than a predetermined value continues for a predetermined time. In these cases, even if the display of the guidance information is turned off, it is considered that there is almost no influence on the vehicle travel guidance. Therefore, the display device can display other images by turning off the display of such unnecessary guidance information. It becomes possible to use for.

  Further, it is desirable that the display interruption means described above resumes the display of the guidance information by the intersection guidance information display means when the traveling state of the host vehicle no longer satisfies the display interruption condition. By displaying the guidance information again, for example, when the traveling of the vehicle stopped before reaching the intersection is resumed, the traveling guidance of the vehicle at the intersection reaching thereafter can be reliably performed.

  In addition, a plurality of the display timings described above exist for one intersection, and when the intersection guidance information display means has stopped displaying the guidance information by the display interruption means before reaching the second and subsequent display timings, It is desirable to display the guidance information again at the second and subsequent display timings. By preparing multiple display timings of guidance information before reaching the intersection, the guidance information once disappeared can be displayed again, and the driving guidance of the vehicle at the subsequently reached intersection can be surely performed. Can do.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation implementation is possible within the range of the summary of this invention. For example, in the above-described embodiment, as shown in FIG. 4, the case where an interrupt guide for guiding a right / left turn intersection is displayed and the intersection guide map is displayed while the surrounding map of the vehicle position is displayed is described. An image other than a map image (an image on an AV screen related to reproduction of at least one of audio and video corresponding to any one of the AV processing unit 14, the TV tuner processing unit 16, and the radio tuner processing unit 18) is displayed on the display device 32. ), The intersection guide map display may be interrupted only when the intersection guide map is displayed over the AV screen image. For example, as shown in FIG. 5 (A), the area around the right half of the display screen as shown in FIG. 5 (B) from the state in which the map around the host vehicle is displayed using the entire display screen of the display device 32. It is assumed that the state of the AV screen image is displayed using In this state, when an interruption for guiding a right / left turn intersection occurs, as shown in FIG. 5C, the state shifts to a state where an intersection guide map is displayed overlaid on the image of the AV screen being displayed.

  FIG. 6 is a flowchart showing an operation procedure of a modified example in which an intersection guide map is displayed before reaching an intersection that turns right or left during route guidance. The operation procedure shown in FIG. 6 is different from the operation procedure shown in FIG. 3 in that step 105 is added between step 104 and step 106. Hereinafter, description will be made by paying attention to the added step 105.

  After the display of the intersection guide map is started (step 104), the display interruption determination unit 132 may display the same area (even if it overlaps completely or partially) before the intersection guide map is displayed. In addition, it may be determined whether or not the AV screen image is displayed on the AV screen image in the table (which may include a case where the intersection guide map is displayed) (step 105). If not, an affirmative determination is made, and the process proceeds to determination of whether or not the display interruption condition in step 106 is satisfied.

  On the other hand, if the AV screen image is not displayed, a negative determination is made in the determination of step 105. In this case, the process proceeds to step 108 to determine whether or not the vehicle has passed the right / left turn intersection. That is, in this case, the process for interrupting the display of the intersection guide map is not performed.

  In this way, when an intersection guide map is displayed while an image other than a map image (for example, an image on an AV screen) is displayed, the display of the intersection guide map can be appropriately deleted. It becomes possible to increase the opportunity to see.

  As described above, according to the present invention, when the display intersection condition is satisfied when the approaching intersection is reached, the display of the guidance information that has been performed until then is interrupted, so that a special operation is performed. Therefore, the guidance information can be erased and the operation can be prevented from becoming complicated.
