In the present embodiment, the vehicle-mounted device 200 is configured integrally with a general car navigation device, and includes a car navigation function and a function of reproducing distribution information, content data, and the like that are push-distributed from the roadside apparatus 100. In other embodiments, an in-vehicle device that does not have a car navigation function may be employed.

  The vehicle-mounted device 200 measures its own position and receives distribution information transmitted from the roadside apparatus 100. For example, the vehicle-mounted device 200 reproduces the distribution information when its own position measured and the geographical position (reproduction position) for reproduction included in the received distribution information match.

  As shown in FIG. 4, the vehicle-mounted device 200 includes a communication unit 201, an audio processing unit 202, an output unit 203, an operation unit 204, an I / O (Input / Output) device 205, a storage device 206, a control unit 207, a ROM 208, A RAM 209 and a system bus 210 are provided.

  The communication unit 201 includes a GPS (Global Positioning System) module 201a and a DSRC (Dedicated Short Range Communication) module 201b.

  The GPS module 201 a receives GPS radio waves from a plurality of GPS satellites and supplies them to the control unit 207. The control unit 207 can acquire the current position of the vehicle-mounted device 200 by controlling the GPS module 201a.

  The DSRC module 201b communicates with the roadside apparatus 100 using the DSRC method.

  The audio processing unit 202 converts the digital audio signal input from the control unit 207 into an analog audio signal using a D / A converter (not shown), and outputs the analog audio signal to the speaker 222. Also, the voice processing unit 202 converts the voice input from the microphone 223 into a digital audio signal by an A / D converter (not shown), and inputs the digital audio signal to the control unit 207. Thereby, the user can hear the voice of navigation and distribution information, or can input the voice.

  The output unit 203 includes a monitor and displays distribution information acquired by the communication unit 201, a navigation image, a television image, a map image stored in advance in the storage device 206, and the like.

  The operation unit 204 includes a touch panel type input device and the like, generates an instruction input signal based on an instruction input by a user, and supplies the instruction input signal to the control unit 207.

  The I / O device 205 includes a DVD-ROM (Digital Versatile Disk-Read Only Memory) drive, reads data from a DVD-ROM or CD-ROM storing predetermined map information (map data), and the like, and controls the control unit 207. To enter. Further, the I / O device 205 acquires a detection signal of a sensor group 225 such as a speed sensor, a travel distance sensor, a direction sensor, and a brake sensor, and supplies the detection signal to the control unit 207.

  The storage device 206 includes a hard disk drive (HDD) and stores distribution information from the route wireless device 100, predetermined map information, various setting information, and the like. The storage device 206 may include another memory such as a memory card. The control unit 207 may read the map information from time to time from a storage medium such as a DVD-ROM that stores the map information, or may read the map information from a recording medium and write it in the storage device 206 in advance.

  The control unit 207 includes a CPU and the like, and controls the operation of the on-vehicle device 200 as a whole. For example, the control unit 207 measures the current position of the vehicle-mounted device 200 (own vehicle) based on the GPS signal received via the GPS module 201a. Further, the control unit 207 takes in the output of the direction sensor included in the sensor group 225 via the I / O device 205 and acquires the current traveling direction of the own vehicle. In addition, the control unit 207 obtains the travel distance of the host vehicle from the output of the travel distance sensor.

  In addition, the control unit 207 receives a message from the roadside apparatus 100 via the DSRC module 201b.

  Since this message is repeatedly transmitted, the control unit 207 determines a change in distribution information by checking an update bit included in the header information of the message.

  In addition, the control unit 207 extracts distribution information from the received electronic message, and determines the type of distribution information included in the electronic message based on an identifier included in the header of the electronic message. Further, the control unit 207 determines whether or not the distribution information includes image information, character information, and audio information based on the presence / absence flag included in the distribution information.

  In addition, when the received distribution information is not an immediate type, the control unit 207 determines the distribution information (more specifically, information (character information, image information included in the distribution information) based on the interrupt setting state. , Audio information)). Details of the interrupt setting will be described later. Note that the control unit 207 may include a coprocessor or the like.

  The ROM 208 stores an operating system (OS), programs, various data, and the like necessary for operation control of the on-vehicle device 200 as a whole.

  The RAM 209 temporarily stores data and programs, and stores distribution information acquired by the communication unit 201, data read from a DVD-ROM, and the like. The control unit 207 uses the RAM 209 as a work memory.

  The system bus 210 is a transmission path for interconnecting the above-described units and transferring commands and data.

  The vehicle-mounted device 200 (information providing apparatus) configured as described above has a great feature in that the distribution information can be reproduced based on an interrupt setting state set in advance by the user. Hereinafter, this feature will be described in detail.

  When receiving a message from the roadside apparatus 100, the control unit 207 extracts distribution information from the received message, and determines the type of distribution information included in the message based on the identifier included in the header of the message. .

  The control unit 207 also acquires the priority of distribution information. The control unit 207 determines the priority of the distribution information based on the information included in the header of the message, the type of distribution information, the information included in the distribution information, and the like. In this embodiment, the priority of distribution information is classified into three categories: “highest priority”, “priority”, and “normal”. “Highest priority” distribution information is immediate information that must be provided to the driver quickly and accurately from the viewpoint of safe driving. For example, safe driving support information and utterance-type safe driving support information fall under this category. To do. The “priority” distribution information is information that is less urgent but highly required to be recognized by the driver from the viewpoint of safe driving. “Normal” distribution information is not urgent information but service-like information (for example, parking lot information) that supports comfortable driving.

  When the priority of the received distribution information is “highest priority”, the control unit 207 immediately reproduces information (character information, image information, or audio information) included in the distribution information (that is, the audio processing unit 202). Alternatively, the data is output from the output unit 203.) As a result, for example, as shown in FIG. 6, urgent information is interrupted and displayed on the monitor even during route guidance. However, when other information belonging to “highest priority” is being reproduced, it is reproduced after the end.

  When the priority of the received distribution information is other than “highest priority”, the control unit 207 determines whether or not a reproduction condition is set for the distribution information. The reproduction condition is a condition regarding the timing at which the distribution information is to be reproduced. For example, geographical position information for reproduction corresponds to this condition. When the reproduction condition is set, the control unit 207 does not perform immediate reproduction, and stores the distribution information in the storage device 206 until the reproduction condition is satisfied. When the reproduction condition is not set or when the reproduction condition is satisfied, the control unit 207 reproduces the distribution information based on the interrupt setting state set in advance by the user.

  Here, the interrupt setting by the user will be described. A user (for example, a driver) of the vehicle-mounted device 200 performs settings for interrupt reproduction of the received distribution information via an interrupt setting screen (see FIG. 5) displayed on the monitor of the output unit 203. The interrupt setting screen is displayed by changing one or a plurality of screens from the navigation screen by a user's touch operation or the like. When there is a request to display the interrupt setting screen, the control unit 207 reads the interrupt setting table recorded in the storage device 206 and generates the interrupt setting screen shown in FIG. 5 based on the contents. , Let the monitor output.

  In the interrupt setting table, whether or not interrupt reproduction is set (ON (performed) or OFF (not performed)) set by the user is stored for each type of information (character information, image information, audio information). In addition, an interrupt display time (interrupt display time) is stored (in this embodiment, any one of 10 seconds, 15 seconds, 20 seconds, or unlimited).

  The user confirms the current setting state by looking at the interrupt setting screen displayed on the monitor, and changes the setting to a desired setting by an operation (such as a touch operation) via the operation unit 204 when the user wants to change the setting. be able to. After the change, when the “return” button is pressed, the screen before the transition is displayed, and the control unit 207 updates the contents of the interrupt setting table to the changes input by the user and stores them in the storage device 206. .

  The control unit 207 determines the reproduction procedure for the distribution information whose priority is not “highest priority” based on the contents of the interrupt setting table and the priority (that is, “priority” or “normal”) of the distribution information. decide. Hereinafter, the determination of the reproduction procedure will be described in detail.

  In the interrupt setting table, there exists an information type (character information, image information, audio information) for which interrupt permission is set to “ON”, and information corresponding to the information type is included in the distribution information. If so, the control unit 207 immediately reproduces the information regardless of the priority (if the reproduction condition is set, the establishment is assumed). However, if information having a priority equal to or higher than the priority of the information to be reproduced is being reproduced, the process waits until the reproduction is completed. Further, the reproduction time when the character information or the image information is reproduced by interruption follows the interruption display time set in the interruption setting table.

  On the other hand, interrupt reproduction cannot be performed for information corresponding to an information type for which the interrupt permission is set to “OFF”. That is, playback is performed in a state where the car navigation function is operating (for example, route guidance, etc.) or in a state where other distribution information is being reproduced (hereinafter, this state is referred to as an “output processing state”). I can't. In this case, the control unit 207 reproduces the information with the priority “priority” after the end of the current output processing state (however, if the reproduction condition is set, the establishment thereof is maintained). Is a prerequisite). On the other hand, information with priority “normal” is not reproduced.

  Subsequently, the procedure of the interrupt reproduction process performed by the vehicle-mounted device 200 of the present embodiment will be described along the flowchart of FIG.

  In this interrupt reproduction process, a reproduction process for distribution information whose priority is other than “highest priority” is executed. The interrupt reproduction process is activated every predetermined time and executes the following series of processes.

  First, the control unit 207 retrieves distribution information stored from the storage device 206 (step S101), and the control unit 207 determines whether a reproduction condition for the distribution information is satisfied (step S102). When the reproduction condition is not set in the distribution information (that is, when the reproduction timing is not specified), it is determined that the reproduction condition is satisfied.

  If the reproduction condition is not satisfied (NO in step S102), the process is exited. On the other hand, when the reproduction condition is satisfied (YES in step S102), the control unit 207 reads the interrupt setting table from the storage device 206, and assigns the information for each information type (character information, image information, audio information). Check the permission status.

  When the interrupt permission is set to “ON” for the type of information included in the distribution information (YES in step S103), the control unit 207 immediately reproduces the information (step S104). In this case, if the information is audio information, audio is output via the speaker 222. If the information is character information or image information, the character or image is output (displayed) on the monitor of the output unit 203. However, when information having a priority equal to or higher than the priority of the information is being reproduced, the information is reproduced after the reproduction is completed. In the case of interrupt reproduction of character information or image information, the reproduction (display) time is the interrupt display time set in the interrupt setting table.

  On the other hand, when the interrupt permission is set to “OFF” for the type of information included in the distribution information (NO in step S103), the control unit 207 checks the priority of the distribution information (step S105). ). When the priority of the distribution information is “priority” (YES in step S105), the control unit 207 reproduces the information after the current output processing state ends (step S106). Note that if the output processing state is not set, the control unit 207 immediately outputs the information. On the other hand, when the priority of the distribution information is not “priority” (that is, “normal”) (NO in step S105), the information is not reproduced.

  As described above, according to the vehicle-mounted device 200 of the present embodiment, the user sets whether to permit the interrupt reproduction of the distribution information for each type of information (character information, image information, audio information). Can do. Then, when the car navigation function is in operation or when information related to other distribution information is being played back, interrupt playback control is performed based on the setting status of the user. Thereby, it is possible to avoid the inconvenience that information with a low priority (for example, parking lot information or the like) is interrupted and reproduced while information necessary for the driver such as route guidance is provided.

  In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

  For example, in the above-described embodiment, the user can set interrupt permission for each piece of character information, image information, and audio information, but the type of information to be set is not limited to this. For example, the types of information such as moving image information, still image information, etc. may be further subdivided so that the presence or absence of interrupt permission can be set for each.

  Also, when the information related to the distribution information of “highest priority” is interrupted and reproduced, the interrupt display time set in the interrupt setting table may be used.

  Also, when audio information is being output (that is, during output processing), if the information to be reproduced is character information or image information, or conversely, output processing is being performed for character information or image information. In the case where the information to be reproduced is audio information, the specification may be such that it can be reproduced immediately regardless of the interrupt setting state.

  In addition, a computer program for operating the vehicle-mounted device 200 as all or part of the device is stored and distributed in a computer-readable recording medium such as a memory card, CD-ROM, DVD, or MO (Magneto Optical Disk). This may be installed in another computer and operated as the vehicle-mounted device 200, or a process performed by the vehicle-mounted device 200 may be executed. Furthermore, the program may be stored in a disk device or the like included in a server device on the Internet, and may be downloaded onto a computer by being superimposed on a carrier wave, for example.
