  Displaying content including a moving image on the display screen while the vehicle is stopped is preferable in terms of increasing pleasure during driving and obtaining various information. However, the stop time is always fluctuating. For example, the stop time at one traffic light is relatively short, for example, 20 seconds, while the stop time at the next traffic light is relatively long, for example, 60 seconds. There is. For this reason, when content that is in the stop time is displayed on the display screen, if the stop time is too short relative to the length of the content, content playback will not be completed. The reproduction of the content ends despite being in the middle, which is not preferable in terms of displaying the content using the stop time effectively.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle information display device capable of displaying content having an appropriate length according to the stop time.

In order to achieve the above object, the following solution is adopted in the present invention. That is, as described in claim 1 in the claims,
Stop determination means for determining that the vehicle is in a stopped state;
Content storage means for storing content including video,
A display unit that is provided at a position that is visible to the driver, and that displays content stored in the content storage unit when the stop determination unit determines that the vehicle is in a stopped state;
A traffic signal information acquisition means for acquiring information relating to a display state of a traffic signal installed on the course of the vehicle;
Reconstructing means for predicting the next stop time based on the information acquired by the traffic signal information acquiring means, and reconfiguring the content to be displayed on the display screen in accordance with the predicted stop time;
It is supposed to be equipped with. According to the above solution, the next stop time at the traffic light is predicted in advance, the content is reconfigured in accordance with the predicted stop time, and then the content reconstructed during the next stop time Is displayed on the display screen, content of an appropriate length is provided in accordance with the stop time, and content that effectively uses the stop time can be provided. In addition, the fact that content with a length corresponding to the stop time is displayed means that the entire content can be provided to the driver without any excess or deficiency. For this reason, various information such as traffic information is provided to the driver. It will be preferable to provide reliably.

A preferred mode based on the above solution is as described in claim 2 and the following claims. That is,
Prediction of the stop time, the route to the destination set by the navigation device mounted on the vehicle, the cycle information of the display switching of the traffic light acquired by the traffic signal information acquisition means, the presence or absence of the preceding vehicle, This is performed based on the vehicle speed of the host vehicle (corresponding to claim 2). In this case, it is preferable to accurately predict the next stop time.

  Further, a notice means for notifying in advance of the contents to be displayed during the next stop time is further provided (corresponding to claim 3). In this case, since the content of the next displayed content is notified in advance, it is preferable for the driver to immediately understand the content when the content is actually displayed.

  In FIG. 1, a vehicle V has a display screen (monitor) for a navigation device 1 and a GPS antenna 2 for navigation in addition to a controller U described later (a navigation device body is not shown). The display screen 4 is provided at a position that is easily visible from the driver, such as the center position of the instrument panel. In the embodiment, the display screen 4 is a display screen for navigation. However, a windshield monitor that projects an image in front of the front windscreen, an air conditioning and an operation unit for audio operation provided on an instrument panel, etc. It may be a monitor for displaying. The controller U is configured using a microcomputer and appropriately changes and controls the display contents on the display screen 1 as will be described later.

  The vehicle V has wireless communication means 3 and 4. Via this wireless communication means 3, it is possible to wirelessly communicate with the traffic control base station K1. The base station K1 distributes information related to the switching time of the display state of each traffic light (so-called DSSS function), so that the display state of the vehicle V is switched at which time the traffic light in the traveling direction changes. It is possible to obtain information on whether or not For example, it is possible to obtain the time at which the traffic light immediately before the vehicle stops is switched from the stop display state (red light state) to the passable display state (green light state) where the vehicle can start. Note that transmission / reception means on the base station K1 side can be installed in each traffic signal so that transmission / reception with the wireless communication means 3 of the vehicle V can be performed at a short distance.

  In the embodiment, the wireless communication unit 4 communicates using the Internet. The wireless communication unit 4 can wirelessly communicate with the content base station K2 serving as a distribution destination of content including moving images via the wireless communication unit 4. It is said that. The base station K2 distributes various contents including moving images in response to requests from the vehicle V. The contents include entertainment, such as movies, sports, and dramas, news, traffic information, and safe driving. Various information such as information, weather information, detailed map information, and various facility information in the vicinity can be distributed. The controller U temporarily stores the delivered content in the storage unit 20 shown in FIG. 2 and displays the content on the display screen 1 on the condition that the vehicle is stopped. The content is not limited to the content distributed from the base station K2, but may be content stored in various storage media such as a DVD brought in by the driver.

  FIG. 2 shows an example of a control system according to the present invention. In FIG. 2, the controller U receives the signal from the GPS antenna 2 and the information via the wireless communication means 3 and 4, as well as the vehicle speed signal from the vehicle speed sensor 11 via the wireless LAN 10, A brake operation signal from the brake sensor 12 is input. The traffic signal information from the wireless communication unit 3 is acquired by the signal cycle information receiving unit 21, and this acquired data is input to the traffic condition data creation processing unit 22. The stop determination unit 21 determines that the vehicle is stopped when the vehicle speed is 0 and the brake pedal is depressed, and outputs the determination result to the traffic condition data creation processing unit 22. Further, when the vehicle speed is not zero or the brake pedal is not depressed, the start determination unit 23 outputs the determination result to the traffic condition data creation processing unit 22 assuming that the vehicle is starting (running).

  A signal from the GPS antenna 2 is input to the own vehicle position determination processing unit 26, and the own vehicle position is accurately determined by the own vehicle position determination processing unit 26, and this determination result is sent to the transmission data creation processing unit 27. Is output. The transmission data creation processing unit 27 also receives the output from the traffic situation data creation processing unit 22 described above. The transmission data creation processing unit 27 transmits traffic signal cycle information and the like to the base station K2 via the wireless communication unit 4. In response to this, the base station K2, as will be described later, predicts the stop time at which the vehicle V will stop next, reconfigures the content to have a length corresponding to the predicted stop time, and re- The configured content is transmitted to the vehicle V (its controller U) via the wireless communication means 4. The reconstructed content transmitted from the base station K2 is temporarily stored in the storage means 20, and the content stored in the storage means 20 is displayed on the display screen 1 when the vehicle stops at the next traffic light. In the embodiment, the notice content for notifying the content is also created and distributed by the base station K2, and the notice content is displayed on the display screen 1 so as to be superimposed on the content displayed while the vehicle is stopped. It has become. The display control processing unit 25 for switching and controlling the display content of the display screen 1 displays the content on the display screen 1 while the vehicle is stopped, and performs normal display (map display for navigation in the embodiment) while driving. Is called.

  The content selection and reconfiguration at the base station K2 will be described. First, as shown in FIG. 2, the base station K2 (or its server device) stores a large number of contents as a database 31 in a large-capacity storage medium such as a hard disk. An example (part) of the database 31 is shown in FIG. 3, for example. Each content is stored in association with its reproduction time, urgency and importance.

  The base station K2 has a traffic situation collecting unit 32. The traffic situation collecting unit 32 can also receive traffic situations from the vehicle V via the wireless communication means 4 and traffic situations from many other vehicles as well. Is acquired. The acquired traffic situation is predicted by the traffic condition analysis unit 33 when the vehicle V requesting content distribution is next stopped at a traffic light in the traveling direction. Based on the predicted stop time, the content reconstruction / distribution unit 35 reconstructs the content selection and the selected content into a length corresponding to the predicted stop time, and distributes the selected content to the vehicle V. The content can be selected as appropriate, such as selecting a content that is longer than the predicted stop time and close to the predicted stop time, or selecting in order of increasing urgency or order of importance. Moreover, you may make it preferentially select the content of the genre according to the request | requirement from the vehicle V (driver). The content restructuring / distributing unit 35 also creates a short notice content (may be a still image) for notifying the content to be provided next together with the content reconfiguration and distributes it to the vehicle V. To do.

  Content reconstruction can be performed by combining, for example, one or more of the following various methods. That is, as a reconstruction method, there are adjustment of the reproduction time (both when reproducing slowly and when reproducing quickly), extraction of highlight scenes, changing the order of stories, omission of some scenes, and the like.

  In the embodiment, the prediction of the next stoppage time at the traffic light of the vehicle V includes the route to the destination set in the navigation device set by the vehicle V, and the traffic signal information regarding the traffic signal display switching time from the base station K1. This is performed based on the presence or absence of a preceding vehicle traveling in front of the vehicle V and the vehicle speed of the vehicle V. The prediction of the stop time will be described with reference to FIG. 4. In FIG. 4, the horizontal axis represents time, and the vertical axis represents the distance for each traffic signal interval along the destination route (the distance to the stop line position corresponding to the traffic signal). ). In FIG. 4, the vehicle V is currently stopped on the stop line T1, but the preceding vehicles VX1, VX2, and VX3 are positioned in front of the vehicle V (such a situation is caused by the position information from other vehicles). Obtained by taking).

  Each vehicle V, VA1 to VX3 departs, and the movement trajectory to the stop line position T2 at the next traffic light on the destination route is indicated by VZ and VZ1 to Z3. The forefront vehicle VX1 that is the foremost in front at the stop line position T1 can start at the earliest timing, travel smoothly without being obstructed by the preceding vehicle, and is not stopped by the traffic light at the next stop line position. It is predicted that it will pass as it is. The second vehicle VX2 from the beginning at the stop line position T1 is stopped by the traffic light at the stop line position T2, but the third vehicle VX3 and the vehicle V from the beginning at the stop line position T1 are the most leading positions. Following the same movement trajectory as the second vehicle VX2, the vehicle V is predicted to stop at the third position from the beginning at the stop line position T2. Since the time when the vehicle V reaches the stop line position T2 is predicted and the display switching timing of the traffic light at the stop line position T2 is obtained from the base station K2, the vehicle V stops at the stop line position T2. Downtime is predicted. Then, the content is reconfigured based on the predicted stop time for the predicted vehicle V.

  5-8 shows the example of a change of the display content on the display screen 1 when the vehicle V repeats driving | running | working and a stop. First, FIG. 5 is traveling, the map information of the navigation device is displayed, and the position on the map corresponding to the vehicle V is shown as VP. The vehicle V is shown traveling in the right direction in FIG. When the vehicle V stops according to the display of the traffic light, the content corresponding to the reproduction time, the urgency level, or the importance level corresponding to the predicted stop time (for example, as shown in FIG. 6, the urgency level is high in FIG. , A moving image showing traffic conditions / congestion information at a predetermined point by a road camera set at a predetermined point on the destination route set by navigation with importance = medium is displayed on the display screen 1. At this time, the content displayed when the vehicle is next stopped is displayed in advance in the upper right of the screen, for example.

  From the state shown in FIG. 6, during the next run after starting, as shown in FIG. 7, the map display by the navigation device is switched, but the position VP of the vehicle V is as shown in FIG. It will move to the right rather than the case of. When the vehicle is next stopped according to the display of the traffic light from the state of FIG. 7, as shown in FIG. 8, the news with the urgency level of FIG. Is displayed. Thereafter, the same thing is repeated. Since the content displayed on the display screen 1 during the stop is reconfigured to a length corresponding to the length of the stop time, all the stop time is used effectively, and the content is accurately provided to the driver. Can be provided. Note that in order to prompt the driver to confirm the forward situation at the time of starting, all the content playback ends slightly before the predicted starting time (for example, 3 to 5 seconds corresponding to the remaining stop time). In this way, the content length may be reconstructed.

  FIG. 9 is a flowchart illustrating an example of control in the base station K2. This flowchart will be described. In the following description, S indicates a step. First, in S1, it is determined whether or not the vehicle V is stopped (the presence or absence of the stop is acquired from the vehicle V side via the wireless communication means 4). When the determination at S1 is NO, the determination at S1 is repeated. When the determination in S1 is YES, in S2, the stop position of the vehicle V (position based on the stop line position corresponding to the traffic light) is acquired. This position information is also acquired from the vehicle V side via the wireless communication means 4.

  After S2, in S3, the position where the next traffic light stops and the stop time Ts are predicted. Thereafter, in S4, content information that can be provided next time is acquired, and then in S5, the content to be provided next time is selected and distributed (the content selected and distributed is the predicted stop time Ts. The content is reconstructed to a length corresponding to the After S5, a preview content of the content to be provided next time is created and distributed to the vehicle V in S6.

  10 and 11 show a case in which long-length contents such as movies, dramas, and animations are divided into four “start / end / change / end” and are sequentially displayed on the display screen 1 for each stop time. 10 corresponding to FIG. 6 shows an example in which the “start” portion is displayed on the display screen 1, and FIG. 11 corresponding to FIG. 8 shows an example in which the “approval” portion is displayed on the display screen 1. . Although illustration is omitted, the “rolling” and “conclusion” portions are similarly displayed on the display screen 1 for each subsequent stop time. Reorganize each part of “start”, “approval”, “turn” and “conclusion” into shorter parts according to the stop time. For example, the “start” part is stopped three times. You can also end the display with.

  FIG. 12 shows that when the destination is set in the navigation device, the base station K2 predicts all stop times to the destination and provides one feature content with the total stop time. An example in the case of That is, in S11, a route from the vehicle V to the destination is acquired, and in S12, all traffic signal information (display switching time) on the destination route is acquired. In addition, acquisition of all the traffic signal information on the destination route can be acquired from the base station K1.

  After S12, in S13, the traveling state of the other vehicle on the destination route, in particular, the traveling state of the other vehicle traveling toward the destination ahead of the vehicle V is acquired. After that, in S14, the position of the traffic light that is stopped until the vehicle V reaches the destination and the stop time thereof are predicted from the stop situation at the traffic light of the other vehicle, and the predicted values of the respective stop times are summed up. Thus, the total stop time for stopping before reaching the destination is calculated. Thereafter, in S15, a long-length content corresponding to the total stop time is selected, and the selected long-length content is reconfigured into a number of divided contents corresponding to the stop time at each traffic light. At the time of this reconstruction, the length of the divided content can be set to a length corresponding to each predicted stop time. Thereafter, in S16, the divided content reconfigured in S15 is provided to the vehicle V in accordance with the next stop.

  Regarding the content reconfiguration example in S15, for example, the individual stop time is 10 minutes such as 1 minute, 2 minutes, 2 minutes, 3 minutes, 2 minutes, 2 minutes, 3 minutes, 1 minute, 2 minutes, 2 minutes, etc. A case will be described in which the total prediction time is predicted to be 20 minutes. In this case, it is assumed that a longer 30-minute content is selected according to the total pause time of 20 minutes. At this time, the 30-minute long content is reconfigured so as to be 20 minutes corresponding to the total pause time (for example, omission of a less important scene). This reconstructed content can be displayed on the display screen 1 for each stop time. In this case, content playback may not be good at the end of the stop time (starting time), but the driver understands that the continuation will be provided at the next stop Therefore, there is no problem in watching the content reconfigured in 20 minutes every stop time. Further, as another method, the content may be divided into ten while the above-mentioned 30-minute content becomes good at the end of each stop time. In this case, the total reproduction time of the ten divided contents is set to 20 minutes, and there is a case where an omitted scene exists in one divided content, but an omitted scene does not exist in another divided content. One piece of content is first reconstructed according to the total stop time (for example, omitted), and then restructured again at each stop time so that each divided content is well-separated at the end of the stop time You may make it do.

  Although the embodiment has been described above, the present invention is not limited to the embodiment, and can be appropriately changed within the scope described in the scope of claims. For example, the invention includes the following cases. . All functions of the base station K2 may be provided on the vehicle V side, or only raw content is acquired from the base station K2, and other stop time prediction, content reconstruction, etc. are performed on the vehicle V side. You may make it perform. Of course, the object of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or expressed as an advantage.

  The present invention is suitable as an information display device using a display screen mounted on a vehicle.
