Description

  The present invention relates to a moving body information output device that outputs information provided to a user of a moving body such as a vehicle.

  2. Description of the Related Art Conventionally, there is known a mobile information output device that provides a user such as a vehicle driver with various types of information such as warnings and cautions about driving and conditions of the vehicle, route guidance, and recommended information through a display device. Yes. In such a device, in response to input of information to be provided (hereinafter, provided information), the provided information is sequentially output, but a plurality of provided information is input at substantially the same timing. Not a few. In view of this, a technique has been proposed in which a plurality of pieces of provision information input at substantially the same timing are compared to give priority, and an example of such a technique is described in Patent Document 1.

  The information processing apparatus described in Patent Document 1 automatically collects and refers to information on a network to automatically process the determination of the importance of information to be provided to a user. It is an apparatus that assists the determination processing by. That is, the information processing apparatus automatically collects, analyzes, and compares information that can be collected on a computer network, thereby determining the importance of each information provided on the information providing site. . Through this determination, important information is clearly shown to the user, and this is preferentially provided to the user. Further, the information processing apparatus assists the determination work of the importance and priority of the information provided by the editor of the information providing site or performs all the determination processing automatically.

JP 2001-209655 A

According to the information processing apparatus described in Patent Literature 1, information on a network and the like can be provided to a user according to importance.
By the way, for example, information provided to the user of the vehicle includes information that is set with a high priority in view of its importance, such as information related to the running and state of the vehicle, particularly information related to safety. When output of a plurality of provision information is requested at the same time, the provision information having a higher priority is usually given priority over the information having a lower priority. However, in recent years, in order to improve the convenience for the user, the provided information output by the vehicle tends to be diversified. In other words, the provided information does not necessarily have a high priority, but it often includes information that is valuable to be notified at the "time" and "on the spot" when moving. . However, provided information that is valuable to be notified at that time and “on the spot”, when the output timing competes with high priority information, the output is postponed, and as a result, the value of the information It may be reduced or lost, or the output opportunity itself may be lost.

  In addition, even if there is no priority for the output of a plurality of provided information with overlapping output timings, the same problem as described above is unavoidable when the output timing is adjusted. Moreover, such a problem arises similarly about mobile bodies other than a vehicle.

  The present invention has been made in view of such circumstances, and its purpose is to adjust the output mode so that a plurality of pieces of information with overlapping output timings can be output as much as possible. An object of the present invention is to provide a mobile information output device.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
In order to achieve the above object, a mobile information output device is a mobile information output device that outputs information input in real time to be provided to a user of a mobile device, and for each information to be provided. The attribute assigning unit for assigning, as attributes, a possible waiting time that is the length of time that the output can be waited and a minimum output time that is the minimum required output time, respectively, Of the two pieces of information that should have the same output timing, when the waiting time given to one information is longer than the minimum output time given to the other information, the other information is assigned to the other information. The information is output in such a manner that the information is output for a length equal to or longer than the minimum output time of the information and then the one information is switched to the other information within the waiting time of the one information. Comprising an output arbitration section for arbitrating, wherein the attribute assigning unit may further output duration as the allowable waiting time and the minimum output time over the length of time the sum of the attributes for each information to be provided the And the output arbitration unit sets the output time of the other information to the other information when the output duration given to the other information is shorter than the waiting time of the one information. The gist is to set the information output duration or longer .

  According to such a configuration, when there are a plurality of pieces of information to be provided (provided information), the waiting time and the minimum output time of the two provided information whose output timings overlap each other are compared, and the two information are output together. As described above, the output mode of each information is arbitrated. As a result, more output opportunities are given to each piece of information, and a plurality of pieces of information with overlapping output timings are adjusted to output as much information as possible.

In addition, according to such a configuration, by setting the output continuation time in which the output time for outputting information is longer than the minimum output time, the recognition of the information to be output can be enhanced. Therefore, it becomes easy to make a user recognize the notified information.

  As a preferred configuration, when the output time of the information to be provided is the minimum output time of the information to be provided, the output arbitration unit corresponds to the information to be provided instead of the information to be provided. The simplified expression information prepared in advance as the simplified information is output.

  According to such a configuration, when the output time is the minimum output time, the information to be output is simplified expression information so as to enhance the cognition of the information to be provided even if the output time is short. Can be. That is, even if the output time is short, the content of information to be provided can be recognized more reliably.

As a preferred configuration, the output arbiter unit, when the output time of the providing information to be shorter than the output duration of the information to be provided said, instead of the information to be provided said, corresponds to the information to be provided the Thus, simplified expression information prepared in advance as information obtained by simplifying the expression is output.

  According to such a configuration, when the output time is shorter than the output continuation time, by providing the simplified expression information, it is possible to maintain the recognition of the information to be provided even if the output time is somewhat shortened. become able to.

  As a preferred configuration, the attribute assignment unit further assigns, as an attribute, a priority indicating the priority order of provision for each piece of information to be provided, and the output arbitration unit includes the information with the high priority assigned. The switching timing is adjusted in such a manner that a long time is output.

According to such a configuration, since the output time of information with high priority is secured for a longer time, the recognition of information with high priority is further enhanced.
As a preferred configuration, the output arbitration unit adjusts the switching timing in a manner that ensures that the information to be provided is output for a long time in a first-come-first-served basis.
In order to achieve the above object, a mobile information output device is a mobile information output device that outputs information input in real time to be provided to a user of a mobile device, and for each information to be provided. The attribute assigning unit for assigning, as attributes, a possible waiting time that is the length of time that the output can be waited and a minimum output time that is the minimum required output time, respectively, For two pieces of information whose output timing overlaps among the power information, when the waiting time given to one information is longer than the minimum output time given to the other information, the other information is set to the other information. The information is output in such a manner that the information is output for a length equal to or longer than the minimum output time of the information and then the one information is switched to the other information within the waiting time of the one information. And an output arbitration section for arbitrating, the output arbitrator, said should provide information in order of arrival, to adjust the timing of switching the in a manner that the time to be outputted is ensured long.

According to such a configuration, it is possible to reduce the risk that the previously issued information will not be recognized by ensuring a long output time of the previously issued information to be provided.
As a preferred configuration, the minimum output time is an attribute given as a minimum length of time required for a user to recognize the information to be provided.

  According to such a configuration, it is possible to maintain the minimum recognition of the information to be output by securing the minimum output time as the information output time. And it becomes possible to output more information while maintaining the cognition.

  The navigation system 150 provides route guidance to the vehicle 10 based on the current position of the vehicle 10 acquired from the position detection unit 101, the set destination, and the stored road map data. When the destination is set, the navigation system 150 searches for a travel route from the current position of the vehicle 10 to the destination, and displays the retrieved travel route on the display screen in a manner that overlaps the map display. Thereby, route guidance is provided to the driver as an image. In addition, the navigation system 150 selects information to be provided to the user when it detects approaching a point having information that is significant to the driver or information that the driver prefers, and the information that is significant to the selected driver or that the driver prefers. Information is output to the information processing unit 200 as provided information Ie. Information that is meaningful to the driver includes route guidance and information on dealer stores and gas stations that are desired according to the state of the vehicle. Moreover, as information which a driver likes, the information of the restaurant or shop according to a driver's preference is mentioned. The provided information Ie is mainly output as general information.

  The information processing unit 200 inputs the provision information Ia to Ie as information to be provided to the user in real time. The information processing unit 200 can specify the contents of the provided information Ia to Ie acquired by CAN communication based on the message ID of the CAN. Even if the provision information Ia to Ie is input by a communication method other than the CAN communication, the information included in the communication message including the provision information Ia to Ie or the information included in the provision information Ia to Ie The contents of the provided information Ia to Ie can be specified based on the information.

  The information processing unit 200 is a so-called ECU (electronic control unit), and includes a small computer having a calculation unit and a storage unit. And the information processing part 200 can perform various control, when a calculating part calculates and processes the program and parameter which were memorize | stored in the memory | storage part. That is, the information processing unit 200 outputs the output request reception unit 210 that receives the provision information Ia to Ie, the attribute assignment unit 211 that assigns an attribute corresponding to each provision information, and the output order based on the priority corresponding to the attribute. And an information category arbitration unit 220 that determines the presence / absence of arbitration. In addition, the information processing unit 200 includes an output arbitration unit 230 that determines a priority order for outputting the provision information when there is two provision information, an output form selection unit 240 that defines an output form of the provision information, and an output state of the provision information. And an output state management unit 250 for managing the above. Furthermore, the information processing unit 200 includes a storage unit 260 that can store various parameters, programs, data, and the like.

  The storage unit 260 includes a known storage device, and the storage unit 260 includes a waiting queue 261 that waits for information that is waiting for output, and provided information that corresponds to the message ID of the CAN. An attribute list 262 that holds attributes corresponding to is held. The waiting queue 261 can input and output provision information, and the input provision information is additionally stored on a first-come-first-served basis after provision information already stored. In addition, the standby queue 261 outputs the provision information at the head, and deletes the provision information that has been output, and sequentially advances the order of the provision information that has already been stored. The attribute list 262 holds information categories (information priority), standby time, minimum output time, output continuation time, and the like as attributes corresponding to provided information. It should be noted that at least the required attribute has only to be set as the attribute corresponding to the provided information. In the present embodiment, at least the standby time and the minimum output time may be held.

  Here, the attribute corresponding to the provided information will be described. First, the information category (information priority) is information for classifying the content of the provided information into an appropriate category, and a priority according to the classified category is given. In the present embodiment, the category is divided into warning information, caution information, and general information. The warning information and caution information have a high priority, and the general information has a lower priority than the warning information and caution information. Priority is given.

  As shown in FIG. 4A, the waiting time, the minimum output time, and the output continuation time are associated with “Information 1” as the standby time St1, the minimum output time Nt1, and the output continuation time Ot1. As shown in FIG. 4B, “information 2” is associated with a waiting time St2, a minimum output time Nt2, and an output continuation time Ot2.

  Each waiting time St1, St2 is the length of time that can be waited until the provision information is output, and is the length of time from the current time to the time when the information must be notified. The waiting time is, for example, a time during which the output of the lane restriction information can be waited when the position where the lane restriction information is obtained is away from the distance at which the lane change can be appropriately performed. In the case of a mobile object, the waiting time is calculated from the speed and the distance, and such time can be replaced by the distance or the speed.

  Each minimum output time Nt1, Nt2 is a length of time required at least for the output provided information to be recognized by a user such as a driver. This minimum output time is set to a time longer than the time when there is a high possibility that the user cannot recognize, and at least the minimum output times Nt1 and Nt2 are output so that the provision information is highly likely to be recognized and maintained. It is. For example, when the provided information is text information or voice information, the length of time that the content of the text information or voice information is considered to be recognizable is set as the minimum output time. When text information or voice information is "There was new mail", when it is possible to recognize "new mail", when displaying text sequentially in a narrow display area, when outputting in voice If so, the time required to utter until “new mail” is set as the minimum output time.

  Each output continuation time Ot1, Ot2 is the length of time from the current time to the time when the provision information is desired to be output, and the waiting time St1, St2 and the minimum output time Nt1 associated with the provision information. , Nt2 is set to a time longer than the sum. For example, each output duration Ot1, Ot2 sets the time required for a user such as a driver to recognize the provided provided information with a margin, or the contents of the provided information are completely output. It is possible to set the time required for the information to be provided or to set the time until the timing at which the provision value of the provided information is lost. Note that the provided information may be switched to the next information when there is information to be output next, even if the output continuation times Ot1 and Ot2 are set. When there is no output, the output may be continued even after the output duration has elapsed.

Next, operations of the output order setting process and the information output process performed by the information processing unit 200 will be described in order with reference to FIGS.
First, as illustrated in FIG. 2, the information processing unit 200 starts the output order setting process when the provision information Ia to Ie is input. When the output order setting process is started, the output request receiving unit 210 sequentially receives the input provided information Ia to Ie as the target of the output order setting process (step S10). The output request accepting unit 210 selectively accepts the provision information Ia to Ie that is the target of the output order setting process by filtering the message ID of the CAN.

  When the target provision information Ia to Ie is received, the attribute assigning unit 211 specifies and assigns information attributes to the received provision information Ia to Ie (step S11). The attribute assigning unit 211 acquires the message ID of the CAN corresponding to the provided information Ia to Ie, specifies the information attribute corresponding to the acquired message ID from the attribute list 262, and sets the specified information attribute to the provided information Ia Correspond to ~ Ie. Thereby, the information category (information priority), the standby time, the minimum output time, and the output duration time are associated with the provided information Ia to Ie.

  When the information attributes are associated with the provided information Ia to Ie, the information category mediation unit 220 performs information category mediation (step S12). Information category arbitration refers to an information category (information priority), and sets the priority of information that is warning information or caution information to be high, and sets the priority of information that is general information to be low. And the information category mediation part 220 judges whether the priority based on the information category of provision information Ia-Ie is high (step S13). When it is determined that the priority of the provision information Ia to Ie is high (YES in step S13), the information category mediation unit 220 performs output state management in the output state management unit 250 so as to output the provision information Ia to Ie quickly. Is performed (step S16). In the present embodiment, general information with low priority is targeted for output mediation, while warning information and caution information with high priority are excluded from output mediation. Thereby, the warning information and the caution information are promptly notified. Details of output state management will be described later.

  On the other hand, when it is determined that the priority of the provision information Ia to Ie is not high (NO in step S13), the output arbitration unit 230 adjusts the output order of the provision information Ia to Ie (step S14). The output arbitration unit 230 outputs the provision information Ia to Ie without adjusting the output order when only one provision information Ia to Ie is input before the next output becomes possible. 240 (proceed to step S15). On the other hand, when two provision information Ia to Ie is input before the next output becomes possible, the output arbitration unit 230 adjusts the output order thereof. These two provided information Ia to Ie are information received until the next output becomes possible, and are often continuous information. For example, it consists of provision information Ia to Ie input to the information processing unit 200 at substantially the same timing.

  Here, with reference to FIGS. 5A to 5D, the output order arbitration of the two provision information Ia to Ie performed by the output arbitration unit 230 will be described. Here, for convenience of explanation, one of the two provision information Ia to Ie will be described as “information 1” and the other as “information 2”. The output arbitration unit 230 arbitrates the output order of “information 1” and “information 2” based on the relationship between the waiting time of “information 1” and “information 2” and the minimum output time. Here, the attribute of “information 1” is indicated as standby time St1 and minimum output time Nt1, and the attribute of “information 2” is indicated as standby time St2 and minimum output time Nt2. As illustrated in FIGS. 5A to 5D, the relationship between the attributes of “information 1” and “information 2” includes “minimum output time Nt1 <standby time St2” and “minimum output time Nt2>. The waiting time is St1 ”. That is, as shown in FIG. 5B, while it is possible to output “Information 1” while waiting for the output of “Information 2”, while waiting for the output of “Information 1”. “Information 2” cannot be output. Therefore, the output order of “information 1” and “information 2” is “◯” (possible) in the order of “information 1” → “information 2”, and the order of “information 2” → “information 1” is “ X ”(impossible). Therefore, when the output order is changed from “information 1” to “information 2”, as shown in FIG. 5D, “information 1” can be output only for the minimum output time Nt1 (output pattern 1), or As shown in FIG. 5E, “information 1” can be output until the standby time St2 of “information 2” (output pattern 2). In “output pattern 1”, the minimum recognizability of “information 1” is ensured, while “information 2” is secured for a long output time to enhance the recognizability. In the “output pattern 2”, the “information 1” is secured with a long output time to enhance the cognition, while the “information 2” has the minimum necessary cognition.

  The output arbitration unit 230 sets the output order of “information 1” and “information 2” in the order “information 1” → “information 2”, and selects “output pattern 1” or “output pattern 2”. The output arbitration unit 230 may increase the output time of information received first by the output request reception unit 210 (in order of arrival). For example, when “information 1” is received first, “output pattern 2” may be selected, and when “information 2” is received first, “output pattern 1” may be selected. Further, the output arbitration unit 230 may be configured to lengthen the output time of information with high importance of information instead of the order of reception. For example, when “information 1” has a high importance level, “output pattern 2” can be selected, and when “information 2” has a high importance level, “output pattern 1” can be selected. The importance level can be given by further classifying the general information, or the priority level can be given by classifying in more detail, or given based on the size of the CAN message ID. You can also

  When the output pattern including the output order is selected, the output form selection unit 240 selects the output form of “information 1” (step S15). When the time for outputting “information 1” is the minimum output time Nt1, the output form selection unit 240 changes the output form of information output as “information 1” to the form of simplified expression information. Simplified expression information is information that is simplified so that the contents of the provided information can be conveyed in a short time, and the contents are accurate even if the time is shorter than the normal output expression prepared as provided information. It is information that can be made to be recognized. By using the simplified expression information, it is possible to enhance the cognition of the provided information even if the output time is short. That is, even if the output time is short, the contents of the provided information can be recognized more reliably.

  The simplified expression information is prepared in advance so as to be associated with the normal output expression of the provided information. For example, a correspondence table (not shown) prepared in advance is set in the storage unit 260. As an example, when the normal output expression is “There was a new mail”, “Email” is prepared in advance as simplified expression information corresponding to this. That is, when the provided information is text information, simplified expression information that is simply expressed in a manner that reduces the user's uncomfortable feeling can be used. In addition, by using appropriately omitted character information, it becomes possible to make the user accurately recognize the contents of the provided information in a short time. Further, for example, when the display range of the provided information is limited, simplified expression information that is simplified to an aspect that can reduce the time required for display can be used.

  Further, when the output time of “information 2” is the minimum output time Nt2, the output form selection unit 240 changes the output form of information output as “information 2” to the form of simplified expression information. You may do it.

  The output state management unit 250 manages the output state of the information so that “information 1” and “information 2” are output in accordance with the output order and the output mode specified so far (step S16). Upon receiving “information 1” and “information 2”, the output state management unit 250 stores “information 2” whose output order is determined later in the standby queue 261 together with the output mode determined thereto. On the other hand, the output state management unit 250 sets “information 1” with the output order first as the output target information, and ends the output order setting process.

  Subsequently, as shown in FIG. 3, “information 1” and “information 2” are output by the information output process. When “information 1” is set as the information to be output, the output state management unit 250 performs an information output process for outputting “information 1” in a predetermined output time and output mode. That is, the output state management unit 250 sets “information 1” as output target information in the output state management, and accepts the set “information 1” as an output processing target (step S20). Then, the output state management unit 250 sets the period defined in “information 1” as the output period, sets the identified output mode as the output mode, and outputs information according to these settings (step of FIG. 3). S21). At this time, for example, the minimum output time Nt1 or the standby possible time St2 is set as the output period. In addition, the output state management unit 250 outputs a signal for outputting “information 1” to at least one of the display device 160 and the audio output device 170 according to the set output mode. Then, the signal output from the output state management unit 250 is transmitted to the display device 160 and the sound output device 170, and “information 1” is output from the display device 160 and the sound output device 170 in a manner that can be recognized by the user. .

  Then, when the output period of “information 1” elapses, the output state management unit 250 ends the information output (step S22). Thereby, the output of “information 1” from the display device 160 and the audio output device 170 is terminated. Then, the output state management unit 250 determines whether or not other provision information is waiting for output (step S23). The output state management unit 250 refers to the standby queue 261 to check whether there is other provision information waiting for output. For example, if it is determined that there is output waiting because “information 2” is stored in the standby queue 261 (NO in step S23), the output state management unit 250 displays the head information (here) Then, “information 2”) is acquired. Then, the output state management unit 250 returns the process to step S20, and performs the process of receiving the acquired “information 2” as information to be output (step S20).

If it is determined that there is no output waiting in the standby queue 261 (YES in step S23), the output state management unit 250 ends the information output process.
According to such a moving body information output device, it is possible to adjust the output mode so that a plurality of pieces of information whose output timing overlaps can be output as much as possible.

As described above, according to the mobile information output device according to the present embodiment, the effects listed below can be obtained.
(1) When there are a plurality of pieces of provision information Ia to Ie, that is, “information 1” and “information 2”, standby times St1 and St2 of “information 1” and “information 2” whose output timings overlap each other and the lowest output The time Nt1 and Nt2 are compared, and the output mode of each information is adjusted so that these two pieces of information are output together. As a result, more output opportunities are given to each piece of information, and a plurality of pieces of information with overlapping output timings are adjusted to output as much information as possible.

  (2) When the output time is the minimum output time Nt1, Nt2, the information to be output is simplified expression information, so that information to be provided even if the output time is short, such as “information 1” and “ It is possible to enhance the cognition of “information 2”. That is, even if the output time is short, the content of information to be provided can be recognized more reliably.

(3) By ensuring a longer output time of high priority information, the recognition of high priority information is further enhanced.
(4) By securing a long output time for information to be provided that has been issued earlier, the risk of the previously issued information not being recognized can be reduced.

  (5) By ensuring the minimum output time as the minimum time required for the user to recognize, the minimum recognition of the information to be output can be maintained. . And it becomes possible to output more information while maintaining the cognition.

(Second Embodiment)
A second embodiment of the mobile information output device will be described with reference to FIGS. In this embodiment, the output mediation unit 230 mediates “information 1” and “information 2” to which attributes different from the attributes exemplified in the first embodiment are assigned. Therefore, hereinafter, the configuration and processing different from those of the first embodiment will be described, and for the convenience of description, detailed description of the same configuration and processing will be omitted.

  6A to 6D show examples of output arbitration when the relationship between the attributes of “information 1” and “information 2” is “output duration time Ot1 <standby time St2”. At this time, as shown in FIG. 6B, while it is possible to output “Information 1” while waiting for the output of “Information 2”, it is waiting for the output of “Information 1”. “Information 2” cannot be output in the meantime. Therefore, the output order of “Information 1” and “Information 2” is “O” (possible) in the order of “Information 1” → “Information 2”, and the order of “Information 2” → “Information 1” is “ X ”(impossible). Therefore, when the output order is changed from “information 1” to “information 2”, as shown in FIG. 6D, “information 1” can be output only for the output duration time Ot1. As a result, “information 1” is secured for a long output time to enhance the cognition, and “information 2” is secured for the minimum necessary cognition. Although not shown, it is also possible to select to output “information 1” for the standby time St2 of “information 2” or to output only the minimum output time Nt1. As a result, output arbitration is performed so that “information 1” and “information 2” with overlapping output timings are output together based on comparing only the time attribute consisting of the minimum output time and the output continuation time. .

  FIGS. 7A to 7E show examples of output arbitration when the relationship between the attributes of “information 1” and “information 2” is “output continuation time Ot1> standby time St2> minimum output time Nt1”. Show. At this time, as shown in FIG. 7B, it is possible to output “information 1” while waiting for the output of “information 2”, and “standby time St1 ≧ minimum output time Nt2”. It is also possible to output “information 2” while waiting to output “information 1” under the conditions of On the other hand, under the condition “standby time St1 <minimum output time Nt2”, “information 2” cannot be output while “information 1” is being output. Therefore, the output order of “Information 1” and “Information 2” is “O” (possible) in the order of “Information 1” → “Information 2”, and the order of “Information 2” → “Information 1” is Under the condition of “St1 ≧ Nt2,” “◯” (possible), and under the condition of “St1 <Nt2,” “x” (impossible). Therefore, when the output order is changed from “information 1” to “information 2”, as shown in FIG. 7D, “information 1” can be output only for the minimum output time Nt1 (output pattern 1). As a result, the minimum recognizability is ensured for “information 1”. When the output order is changed from “information 2” to “information 1”, as shown in FIG. 7E, “information 2” can be output only for the minimum output time Nt2 (output pattern 2). As a result, the minimum necessary cognition is ensured for “information 2”. Which output order is selected can be determined by the importance of information, the first-come-first-served basis, or the like. For example, if the relationship of importance between “information 1” and “information 2” is ““ H ”(information 1)>“ L ”(information 2)”, “information 1” is more reliably recognized. An output pattern is selected. Thus, output arbitration is performed so that “information 1” and “information 2” with overlapping output timings are output together based on comparing only their time attributes.

  FIGS. 8A to 8E show examples of output arbitration when the relationship between the attributes of “information 1” and “information 2” is “output continuation time Ot2> standby time St1”. At this time, as shown in FIG. 8B, while it is possible to output “Information 2” while waiting for the output of “Information 1”, it is waiting for the output of “Information 2”. “Information 1” cannot be output in the meantime. Therefore, the output order of “information 1” and “information 2” is “o” (possible) in the order of “information 2” → “information 1”, and the order of “information 1” → “information 2” is “ X ”(impossible). Therefore, when the output order is changed from “information 2” to “information 1”, as shown in FIGS. 8D and 8E, “information 2” is output as the minimum output time Nt2 (output pattern 1) or output. Only the duration Ot2 (output pattern 2) can be output. Thus, output arbitration is performed so that “information 1” and “information 2” with overlapping output timings are output together based on comparing only their time attributes.

  9A to 9E show examples of output arbitration when the relationship between the attributes of “information 1” and “information 2” is “output continuation time Ot2> standby time St1> minimum output time Nt2”. Show. At this time, as shown in FIG. 9B, it is possible to output “information 2” while waiting for the output of “information 1”, and “standby possible time St1 ≧ minimum output time Nt2”. Under the conditions, “information 1” can be output while waiting for the output of “information 2”. On the other hand, under the condition “standby time St1 <minimum output time Nt2”, “information 1” cannot be output while “information 2” is being output. Therefore, the output order of “information 1” and “information 2” is “information 2” → the order of “information 1” is “O” (possible), and the order of “information 1” → “information 2” is Under the condition of “St1 ≧ Nt2,” “◯” (possible), and under the condition of “St1 <Nt2,” “x” (impossible). Therefore, when the output order is changed from “information 2” to “information 1”, as shown in FIG. 9D, “information 2” can be output only for the minimum output time Nt2 (output pattern 1). As a result, the minimum necessary cognition is ensured for “information 2”. When the output order is changed from “information 1” to “information 2”, as shown in FIG. 9E, “information 1” can be output only for the minimum output time Nt1 (output pattern 2). As a result, the minimum recognizability is ensured for “information 1”. Which output order is selected can be determined by the importance of information, the first-come-first-served basis, or the like. Thus, output arbitration is performed so that “information 1” and “information 2” with overlapping output timings are output together based on comparing only their time attributes.

  For reference, FIG. 10 illustrates a case where mediation cannot be performed so that both “information 1” and “information 2” are output depending on the comparison of time attributes. In this case, the output information is selected based on predetermined conditions such as the importance of information and the order of arrival.

  10A to 10D show examples of output arbitration when the relationship between the attributes of “information 1” and “information 2” is “output continuation time Ot1> minimum output time Nt1> standby time St2”. Show. At this time, as shown in FIG. 10B, “information 2” cannot be output while waiting for the output of “information 1”, and while waiting for the output of “information 2”. “Information 1” cannot be output. Therefore, the output order of “information 1” and “information 2” is “x” (impossible) in both the order of “information 2” → “information 1” and the order of “information 1” → “information 2”. Become. Therefore, as shown in FIG. 10 (d), here, the importance relationship between “information 1” and “information 2” is “H” (information 1)> “L” (information 2) ”. For example, “information 1” is provided information with a high priority, and only “information 1” is output, and “information 2” is not output. As described above, even when the time attributes are compared, as a result, only information with high priority may be output according to the priority of “information 1” and “information 2”. .

  According to such a mobile information output device, for a plurality of information with overlapping output timings, the output mode is adjusted so that the information can be output as much as possible based on the comparison of the time attributes of the provided information. Can do.

  As described above, according to the mobile information output device according to the present embodiment, in addition to the effects (1) to (5) described in the first embodiment, the following effects can be obtained. Be able to.

  (6) By setting the output continuation times Ot1 and Ot2 that are longer than the minimum output times Nt1 and Nt2 to output information, the recognizability of the output information can be improved. Therefore, it becomes easy to make a user recognize the notified information.

(Third embodiment)
A third embodiment of the mobile information output device will be described with reference to FIG. The present embodiment is different from the aspect described in the first and second embodiments in that the information category arbitration unit 220 and the output arbitration unit 230 perform processing in consideration of subdivided priorities. Therefore, hereinafter, configurations and processes that are different from those of the first and second embodiments will be described, and for convenience of description, detailed descriptions of the same configurations and processes will be omitted.

  As shown in FIG. 11, the information category (information priority) included in the attribute given to the provided information includes “emergency”, “alarm, warning”, “warning”, “FB ( Feedback) information ”,“ general information ”, and“ post facto information ”. “Emergency” is a category of information that informs a serious danger. “Alarm, warning” is a category of information that informs danger. “Awareness” is a category such as information that informs the increased risk. “FB (feedback) information” is a category such as information that informs a response such as an operation result of the vehicle 10 to an operation. “General information” is a category such as information that allows the user to select whether or not to accept the provided information. “Post-event information” is a category such as information that does not require real-time performance, such as driving evaluation results.

  Each of the above information categories is assigned a corresponding priority. For example, a priority “5” is assigned to “emergency”, a priority “4” is assigned to “alarm and warning”, “Revocation” has priority “3”, “FB Information” has priority “2”, “General Information” has priority “1”, and “Post-Information” has priority “0” Each is given.

  The information category arbitration unit 220 determines that the priorities “5” to “3” are high priorities and the priorities “2” and “1” are low priorities. Therefore, the information category mediation unit 220 determines that the provided information whose information category (information priority) is “emergency”, “alarm, warning”, and “warning” is not subject to output mediation. On the other hand, the information category mediation unit 220 determines that the provided information whose information category (information priority) is “FB information” and “general information” is a target of output mediation. Then, the information category mediation unit 220 performs output mediation on “general information”. In addition, since the real-time property is not required for the output of “post-event information”, when the output timing overlaps with other information, the output is preferentially waited and is not subject to output arbitration.

  Further, the output arbitration unit 230 considers the priority of the information category when outputting the arbitrated information. For example, when both “information 1” and “information 2” can be output, and both can be output first, the information to be output first is selected according to the priority level. In addition, for example, when both “information 1” and “information 2” can be output and there is a difference in output time, an output opportunity for increasing the output time according to the high priority is given. To do. Further, for example, when only one of “information 1” and “information 2” can be output, the provision information to be output is selected based on the high priority.

  Thus, output arbitration is performed so that “information 1” and “information 2” having the same output timing can be output together as much as possible based on the comparison of their time attributes and the comparison of their priorities.

  As described above, according to the mobile information output device according to the present embodiment, in addition to the effects (1) to (6) described in the first and second embodiments, the following is described. An effect comes to be acquired.

(7) By ensuring a longer output time for high-priority information, recognition of high-priority information can be further enhanced.
