DETAILED DESCRIPTION OF THE INVENTION
An embodiment in which the information reception availability notification device of the present invention is applied to a mobile communication system that performs road-to-vehicle communication between a base station and an in-vehicle information terminal will be described.
[0009]
<< First Embodiment of the Invention >>
FIG. 1 shows a configuration of a mobile communication system according to the first embodiment. This mobile communication system includes an information center system 150 as a base station that distributes various types of information and an in-vehicle information terminal device 100 that receives various types of information. Although FIG. 1 shows only one information center system and one in-vehicle information terminal, there may be a plurality of information center systems, and of course, the in-vehicle information terminal is mounted on many vehicles.
[0010]
The in-vehicle information terminal device 100 includes a mobile phone 101, an input device 102, a GPS receiver 103, a vehicle speed sensor 104, a microcomputer 105, a road map database 106, a communicable area map database 107, a display device 108, a storage device 109, and the like. ing. In this embodiment, an example in which communication with the center system 150 is performed via the mobile phone 101 is shown. However, a communication device that performs wireless communication with the center system 150 is not limited to the mobile phone 101, and may be, for example, an in-vehicle phone. May be.
[0011]
The input device 102 includes an operation member for a driver to input various data such as a destination and an operation member for operating a display screen of the display device 108. The GPS receiver 103 receives a signal radio wave from a GPS satellite and detects the current location of the vehicle. The vehicle speed sensor 104 detects the traveling speed V [km / h] of the vehicle. A road map of the whole country is stored in the road map database 106.
[0012]
The communication availability area map database 107 stores a communication state for each point on the road. The communication state for each point on the road will be described later.
[0013]
The display device 108 includes an LCD 108a and a switch unit 108b, and displays a road map and various types of information. The switch unit 108b is a touch panel switch installed on the surface of the LCD 108a. The storage device 109 stores various information including a travel route and a display-related operation history.
[0014]
The microcomputer 105 includes a CPU 105a, a ROM 105b, a RAM 105c, an A / D converter 105d, and the like. In addition to receiving content from the center system 150, navigation processing such as search for an optimum route to the destination and route guidance, road Display the map and various information.
[0015]
In this embodiment, the in-vehicle information terminal device 100 integrated with the in-vehicle navigation device will be described as an example. However, the in-vehicle information terminal device 100 obtains various contents from the information center system 150 and acquires the driver. The information terminal may be a dedicated information terminal for providing the information to the user, or may be a device that is used in combination with the vehicle-mounted AV device or the like or a combination thereof, in addition to the vehicle-mounted navigation device.
[0016]
The information center system 150 includes a wireless communication device 151, a control device 152, a management server 153, a content server 154, and the like. The management server 153 performs user management, billing management, content management, and the like. Various contents are stored in the content server 154, and it is possible to answer a content availability inquiry from the management server 153.
[0017]
Here, the communication availability area map will be described. In this embodiment, the communication state is evaluated in three stages: good, normal, and difficult. Based on the success and failure of communication with the center system 150 on the road on which the host vehicle and other vehicles have traveled, the reception sensitivity is high and the communication can be performed without any problems, and the communication sensitivity is temporarily set. However, if communication is possible, the normal communication state is assumed, and if communication is temporarily disabled, the communication state is difficult.
[0018]
The communication state for each predetermined section of these traveling roads is stored in the communication availability area map database 107. The communication state of the road on which the other vehicle has traveled is obtained through the center system 150. If any communication state is already stored in the communicability area map database 107 for the travel road that has newly acquired the communication state, the stored contents are updated with the latest communication state.
[0019]
FIG. 2 shows a communication state along a certain road stored in the communicability area map database 107. In the figure, the communication status is good from 0m to 100m, normal from 100m to 200m, difficult from 200m to 300m, good from 300m to 400m, normal from 400m to 500m It is. Therefore, it is determined that the content can be received from the center system 150 except for the area from the 200m point to the 300m point.
[0020]
In addition, although the example shown in FIG. 2 shows the communication state for every 100 m section on the road, it is not necessary to detect and store the communication state for each predetermined distance section, and the communication state is good, normal, or difficult. What is necessary is just to detect and memorize | store the point which switches to the state, and the communication state after the point.
[0021]
Next, a method for determining whether or not reception is possible for each content will be described. In an environment where communication is performed while moving, it is assumed that the communication state is good when it is predicted that the communication state does not deteriorate from the request for the content until the reception is completed. In this case, the requested content can be received. Further, if it takes time to finish receiving the requested content, for example, partially through a place where the communication state is poor, it is assumed that the communication state is normal. Also in this case, the requested content can be received. On the other hand, when it is expected that the communication will be disconnected in the middle, it is assumed that the communication state is difficult. In this case, the requested content cannot be received.
[0022]
The distance x [m] that the vehicle travels from the content request to the reception completion is the content size (data amount) S [bit], the vehicle speed Vsp [m / s] at the time of the content request, and the average communication speed m [b / s] is obtained by the following equation.
[Expression 1]
x = Vsp · S / m
[0023]
Here, the distance when three types of contents A (S = 5 kB), B (S = 10 kB), and C (S = 15 kB) of different sizes are received while traveling is expressed as an average communication speed m = 9600 [b / s] and vehicle speed Vsp = 10 [m / s] As shown in FIG. 3, the content A is 41.7 m, the content B is 83.3 m, and the content C is 125 m. Among these three types of contents, since A and B can complete reception from the 0 m point to the 100 m point where the communication state is good, the communication state of these A and B contents is good. On the other hand, since the content C cannot be received by the 100 m point where the communication state is good and the reception is completed between the normal 100 m point and the 200 m point where the communication state is normal, the communication state of the content C is normal.
[0024]
FIG. 4 is a flowchart illustrating the content reception availability notification program according to the first embodiment. The operation of the first embodiment will be described with reference to this flowchart. When the main switch (not shown) of the information terminal device 100 is turned on, the control unit 101 of the in-vehicle information terminal device 100 executes this content reception availability notification program.
[0025]
In step 1, a content list is acquired from the management server 153 of the center system 150. In the subsequent step 2, the average vehicle speed Vsp is calculated. As the average vehicle speed, it is conceivable to use the average vehicle speed for a certain past time or the average vehicle speed from a point where the road type has changed. For example, when entering a national road from a branch line, the average vehicle speed is calculated starting from the point where the national road was entered. Moreover, you may calculate the average vehicle speed of the past fixed time after entering a national highway. When traffic information indicating that there is traffic jam or traffic regulation in the traveling direction is provided by VICS or the like, it is desirable to calculate the average vehicle speed in consideration of such traffic information.
[0026]
In step 3, communication state data in the vicinity of the vehicle position on the traveling road is read from the communicability area map database 107. The traveling road is identified by comparing the current position detected by the GPS receiver 103 with the road map data stored in the road map database 106. It is also possible to detect the travel distance and traveling direction of the vehicle, collate the travel locus so far with road map data, perform map matching, and specify the road on which the vehicle is traveling.
[0027]
In subsequent step 4, for each content in the content list obtained from the center system 150, the content size S [bit], the average communication speed m [b / s], the average vehicle speed Vsp [km / h], and the travel road Whether or not reception is possible is determined for each content based on the communication state. That is, the content size S, the average communication speed m, and the average vehicle speed Vsp are substituted into the above formula 1 to calculate the distance x [m] that the vehicle travels until the content reception is completed, and the reception distance x and the travel as shown in FIG. Based on the communication state of the road, it is determined whether the content can be received before reaching the section where communication is difficult.
[0028]
In step 5, the reception permission / inhibition determination result is notified for each content. Here, various notification forms of whether or not content can be received will be described. FIG. 5 shows a first notification form of whether or not content can be received. In the first notification form, the content selection display unit 201 is displayed on the right side of the LCD 108a of the display device 108, and the navigation screen 202 is displayed on the left side of the LCD 108a. In the navigation screen 202, a vehicle position mark 203 is displayed on a road map around the vehicle position.
[0029]
The content selection display unit 201 displays four contents included in the content list obtained from the center system 150. In this content display example, four contents are displayed with icons “content1”, “content2”, “content3”, and “content4”, but the names or contents of the contents are represented instead of these icons. Short sentences may be displayed.
[0030]
The content is selected by the jog dial switch 301 shown in FIG. The jog dial switch 301 is included in the input device 102. When the jog dial switch 301 is rotated, the focused icons are sequentially switched among the contents 1 to 4 displayed on the content selection display unit 201 of the LCD 108a. In this example, “content2” is in focus. The content can be selected by turning the jog dial switch 301 to focus the content desired to be received and pressing the jog dial switch 301.
[0031]
Since the communication state changes from moment to moment while traveling, whether or not content can be received also changes accordingly. Therefore, before the driver makes a content reception request, it is necessary to make the content in a state incapable of reception recognized. Therefore, based on the above-described determination result for each content, for the content in a state where reception is not possible, the number of rotations (operation amount) of the jog dial switch 301 when selecting the content is increased and the content is added. It may be difficult to focus. Alternatively, the jog dial switch 301 may be provided with a force feedback switch that generates a reaction force against the rotation operation, and a reaction force may be applied when selecting a content that cannot be received, thereby making it difficult to select the content. Thus, before requesting reception of content that cannot be received, the driver can be informed that the content is in a state that cannot be received.
[0032]
Next, a second notification form will be described with reference to FIG. A content display unit 402 is provided in a part of the LCD 108 a of the display device 108 to display icons of the contents 1 to 4, and a content selection switch 401 of the input device 102 is displayed below the content display unit 402 corresponding to each content icon. Deploy. Each content selection switch 401 is provided with a force feedback switch, and a reaction force against the pressing operation can be generated as necessary. When the content selection switch 401 is pressed, in the case of receivable content, the switch operates with a small pressing force, and reception can be requested. On the other hand, in the case of content that cannot be received, the switch does not operate unless a large pressing force is applied, thereby notifying the driver that the content cannot be received.
[0033]
A third notification form will be described with reference to FIG. FIG. 8 shows an example in which a touch panel type operation display device 501 is formed by the LCD 108a of the display unit 108 and the touch panel switch 108b. In this example, the area of the content selection unit is changed according to the reception availability state for each content. The area of the selection section of the content that can be received in a good communication state is widened so that the driver can easily see it. In the example of FIG. 8, since the communication state of the “news information” content of the minimum size is good and can be received, the area of the news information selection unit 502 is widened. On the other hand, the area of the selection section for contents that are difficult to communicate and cannot be received is made narrower and difficult for the driver to recognize. In the example of FIG. 8, the “video information” content of the maximum size is difficult to communicate and cannot be received, so the area of the video information selection unit 504 is reduced.
[0034]
In addition, the area of the content selection section that can be received when the communication state is normal is narrower than the area of the content selection section that has a good communication state, and wider than the area of the content selection section that is difficult to communicate to ensure a certain degree of visibility. To do. In the example of FIG. 8, the “weather information” content can be received when the communication state is normal, and the area of the weather information selection unit 503 is smaller than the news information selection unit 502 with good communication state, and from the video information selection unit 504 with difficult communication. Is also big. As a result, the communication state for each content and whether or not it can be received can be instantly recognized, and the driving operation can be prevented from being hindered.
[0035]
In the notification form shown in FIG. 8, a “news” content selection unit 502 having a good communication state and receivable is arranged on the right side of the display device 501. That is, content that can be received with a good communication state is displayed closer to the driver than content that can be received with a normal communication state or content that is difficult to receive and cannot be received. Thus, the “news” content selection unit 502 is arranged closest to the driver of the right-hand drive vehicle, and the reception request operation is facilitated.
[0036]
In addition, in the notification form shown in FIG. 8, the selection unit 504 is provided although it is narrow for “video information” content that is difficult to communicate and cannot be received. May be provided. In this case, since all displayed contents can be received, there is no need to consider whether or not reception is possible, and the visibility is further improved.
[0037]
The fourth notification form will be described with reference to FIG. A content display unit 602 is provided in a part of the LCD 108 a of the display device 108 to display icons representing the name and communication status of the content, and a content selection switch of the input device 102 corresponding to each content below the content display unit 602. 601 is arranged. The icon representing the communication state for each content is a radio wave state display icon widely used in communication devices such as mobile phones. Since content 1 is difficult to receive and cannot be received, an icon whose radio wave status is out of range is displayed. Since the content 4 is in a good communication state and can be received, an icon representing the best radio wave state is displayed. Since the contents 2 and 3 are in a normal communication state and can be received, an icon representing a normal radio wave state is displayed. By using an icon representing a radio wave state that is widely used in communication devices such as mobile phones, it is possible to easily and reliably visually recognize the communication state for each content and whether or not it can be received.
[0038]
In addition, it is desirable that the operation reaction force and the area of the information selection unit in the notification mode described above can be set according to the driver's preference. Therefore, an appropriate type of operation reaction force and a sample value of the area of the information selection unit are stored in the storage device 109 in advance, and the operation reaction force selected by the driver and the area of the information selection unit are determined by the driver. You may make it memorize | store in the memory | storage device 109 for every.
[0039]
In this way, the content list is obtained from the base station, and the content until reaching the point where communication is difficult is determined based on the data amount for each content, the vehicle speed, the communication speed with the base station, and the communication state of the road on the road. Since it is determined whether or not to be received and the determination result is notified, it is possible to easily recognize whether or not each content can be received even during driving, and it is possible to make a content reception request without interfering with the driving operation.
[0040]
<< Second Embodiment of the Invention >>
A second embodiment will be described in which it is determined whether or not each content can be received in consideration of the work time when the content is requested. The configuration of the second embodiment is the same as the configuration shown in FIG.
[0041]
The standard work time at the time of content request is determined from the content selection screen as described above when the communication status and reception availability for each content are displayed, and the content requested to be received is determined, and the input device 102 or the switch unit 108b is operated. This is the time from when a content reception request is input until reception of the content is started. The standard work time varies depending on characteristics such as a driver's body shape, age, and operation proficiency, an operation environment of the in-vehicle information terminal device 100 such as a vehicle type, a driving load during operation, and the like.
[0042]
Here, the difference in the standard work time depending on personal information such as the operator's body shape, age, and operation proficiency will be considered. Personal parameters such as body shape and age are registered at the time of driving or previously registered in the in-vehicle information terminal device 100. The standard work time based on the body type and age is stored in the storage device 109 of the in-vehicle information terminal device 100 as a database, and data that matches the registered parameters is read out. A driver close to the standard body type has a smaller amount of operation load at the time of operation than a driver who does not, and the standard work time tends to be shorter. In addition, since the elderly require a longer time for operation determination than the young, the standard work time tends to be longer.
[0043]
In addition, the method for detecting the operation proficiency level of each driver can be determined by, for example, the time required for a series of operations such as music playback, and how much of the prepared functions are used. When the total operation time of the in-vehicle information terminal device 100 is short, it can be determined that the user is familiar with the operation of the in-vehicle information terminal device 100, and generally the time required to complete the content request operation is short.
[0044]
In calculating the standard work time, the following modifications can be considered. The installation location of the in-vehicle information terminal device differs depending on the vehicle type, and the operation is difficult depending on the arrangement of the in-vehicle information terminal. In general, large vehicles have a large passenger compartment, and the distance from the driver's seat to the in-vehicle information terminal tends to be long, and small vehicles tend to be close. Therefore, a small vehicle with a short distance to the in-vehicle information terminal is easier to operate than a large vehicle with a long distance, and the standard work time for the small vehicle is shorter than that of the large vehicle.
[0045]
In addition, the arrangement of the operating devices of the in-vehicle information terminal differs depending on the vehicle type, and the standard work time varies accordingly. For example, as shown in FIG. 10, in a vehicle in which a steering wheel is mounted with a steering wheel switch 701 for operating an in-vehicle information terminal device, the standard work time is shorter than that in a non-mounted vehicle. In a vehicle in which a steering wheel switch 701 for operating an in-vehicle information terminal device is mounted on the steering wheel, the steering wheel switch 701, an operation switch 702 of the input device 102 installed on the front surface of the in-vehicle information terminal device 100, and two systems of operating devices are provided. Prepare. For vehicles equipped with such a plurality of systems of operating devices, it is detected which operating system the driver is mainly using, and when the handle switch 701 close to the driver's hand is used, the operating switch The standard working time is shortened compared to the case where 702 is used.
[0046]
On the other hand, the standard work time may be calculated in consideration of the driving load during traveling. The magnitude of the driving load can be determined from, for example, the type of road that is running and the running speed. When driving at a constant speed on a highway or a main road that is followed by a straight road, the driving load is low. Compared to this, while traveling on intersections and narrow streets, it takes longer to watch the surroundings and the driving load is high. When the brake operation is frequently performed or when the shift operation is frequently performed, it is considered that the driving load is high. The standard working time is lengthened as the operating load increases.
[0047]
Further, in a low light environment, the time required for visual judgment increases and the standard work time becomes longer. Illuminance outside the vehicle in the driving environment can be detected using an illuminance sensor. Temporary decline in illuminance, such as when passing through a tunnel, has a significant effect on visual judgment.
[0048]
Two types of contents A (S = 5 kB), B (S = 10 kB), and C (S = 15 kB) having different sizes S [bit], which are exemplified in FIGS. 2 and 3 of the first embodiment described above. FIG. 11 shows an example in which the distance when the vehicle is received while traveling is calculated as an average communication speed m = 9600 [b / s], a vehicle speed Vsp = 10 [m / s], and a standard work time of 3 seconds. When the vehicle speed Vsp is 10 [m / s], the vehicle travels 30 m in 3 seconds. When the content reception request is determined and the operation is started at the 0m point, communication with the center system 150 is started from the 30m point after 3 seconds of the standard work time, and reception of the contents A, B, and C is started. .
[0049]
The reception of the content A of S = 5 kB is completed at the 71.7 m point that has run 41.7 m from the 30 m point. Similarly, reception of the content B of S = 10 kB is completed at the 113.3 m point that has run 83.3 m from the 30 m point. Also, the reception of the content C of S = 15 kB is completed at the 155 m point that has run 125 m from the 30 m point. If the communication state on this road is the same as the state shown in FIG. 3, the content A is completely received up to the 100 m point where the communication state is good. is there. Further, although the content B is not completely received by the 100 m point where the communication state is good, the reception is completed by the 200 m point where the communication state is normal, so that the communication state of the content B is normal and can be received. Further, similarly, since the reception of the content C is completed up to the 200 m point where the communication state is normal, the communication state of the content C can be received normally.
[0050]
FIG. 12 is a flowchart illustrating a content reception availability notification program according to the second embodiment. The operation of the second embodiment will be described with reference to this flowchart. When the main switch (not shown) of the information terminal device 100 is turned on, the control unit 101 of the in-vehicle information terminal device 100 executes this content reception availability notification program.
[0051]
In step 11, a content list is acquired from the management server 153 of the center system 150. In the following step 12, the average vehicle speed Vsp is calculated. The calculation method of the average vehicle speed is the same as the calculation method described above in the first embodiment. In step 13, the standard work time is calculated as described above. In step 14, communication state data in the vicinity of the vehicle position on the traveling road is read from the communicability area map database 107.
[0052]
In step 15, for each content in the content list obtained from the center system 150, the content size S [bit], average communication speed m [b / s], average vehicle speed Vsp [km / h], travel road communication Based on the status and the standard work time described above, it is determined whether the content can be received before reaching the difficult communication section. Then, the reception determination result is notified for each content by the above-described notification form.
[0053]
As described above, when determining whether or not each content can be received, the standard operation time of the driver until the driver selects the reception request content by the operation member and the reception of the content is started is considered. Therefore, in addition to the above-described effects of the first embodiment, it is possible to accurately determine whether or not each content can be received.
[0054]
The correspondence between the constituent elements of the claims and the constituent elements of the embodiment is as follows. That is, the mobile phone 101 is communication means, the vehicle speed sensor 104 is vehicle speed detection means, the microcomputer 105 is road identification means, reception availability determination means, operation feeling control means and driving load detection means, and the communication availability area map database 107 is. The storage device, the input device 102 and the display device 108 constitute the notification means, the LCD 108a constitutes the display means, the input device 102 and the switch unit 108b constitute the operation member, and the force feedback switch (not shown) constitutes the operation reaction force variable means. To do. In addition, as long as the characteristic function of this invention is not impaired, each component is not limited to the said structure.
