Note that data exchange between the in-vehicle wireless device 2 and the external connection device 3 is performed via the wireless device side external I / F 25 and the connection device side external I / F 31. Give an explanation.

  First, the wireless device side control unit 26 of the in-vehicle wireless device 2 performs polling (when the in-vehicle wireless device operates as a master device). Further, polling from the in-vehicle wireless device 2 is periodically repeated until a response to the polling is made from the external device 3. Note that the processing in the in-vehicle wireless device 2 is started, for example, when power is supplied to the in-vehicle wireless device 2 and the in-vehicle wireless device 2 is activated.

  Subsequently, the connected device side control unit 33 of the external device 3 responds to polling from the in-vehicle wireless device 2 including a connection request. In response to this response, the wireless device side control unit 26 issues a setting confirmation request for confirming the setting of the external device 3. Note that the setting here refers to the function restriction mode and the normal mode described above.

  Further, in response to a setting confirmation request from the in-vehicle wireless device 2, the connected device side control unit 33 displays mode setting information indicating whether the currently set mode is the function restriction mode or the normal mode. Make a response that contains. In response to this response, the wireless device side control unit 26 notifies the external device 3 that the connection has been completed. In addition, the wireless device side control unit 26 stores the mode setting information in, for example, the RAM of the wireless device side control unit 26 after notifying that the connection is completed. Note that the mode setting information is stored by overwriting the old mode setting information when the old mode setting information is already stored.

  In the present embodiment, the configuration has been described in which the wireless device-side control unit 26 stores the mode setting information after notifying that the connection has been completed, but the configuration is not necessarily limited thereto. For example, the mode setting information may be stored before notifying that the connection is completed. The mode setting information is not limited to be stored in the RAM of the wireless device-side control unit 26, and may be stored in another memory such as the memory 22.

  Subsequently, when the operation policy related information including the information type identifier distributed from the roadside device 1 is received by the wireless unit 21 of the in-vehicle wireless device 2, the wireless device side control unit 26 stores the mode stored in the RAM. The setting information is read, and it is determined whether or not the mode setting information is information indicating the normal mode. The delivery of the operation policy related information from the roadside machine 1 may be performed every predetermined time, or may be performed when the roadside machine 1 detects a vehicle.

  When it is determined that the mode setting information is information indicating the normal mode, the operation policy related information as the notification content is transmitted to the external device 3 and the notification according to the operation policy related information is externally transmitted. An instruction (hereinafter referred to as a notification instruction) to be performed by the connected device 3 is given to the externally connected device 3. The operation policy related information transmitted to the external connection device 3 may be operation policy related information processed for display on a display or audio output with a speaker.

  Subsequently, the connected device side control unit 33 receiving the operation policy related information and receiving the notification instruction notifies the connected device side HMI 32 of the display screen display and LED lighting. Or by audio output from the speaker of the connected device side HMI 32. Furthermore, the connected device side control unit 33 that receives the operation policy related information and receives the notification instruction displays a guidance screen or a warning screen according to the operation policy related information on the display of the connected device side HMI 32 or the operation policy related information. Information notification is performed such that a guidance voice or a warning voice according to the information is output from the speaker of the connected device side HMI 32.

  In addition, when it is not determined that the mode setting information is information indicating the normal mode (that is, when the mode setting information is information indicating the function restriction mode), the information included in the operation policy related information The radio device-side control unit 26 determines whether notification is necessary according to the type identifier. Therefore, the wireless device side control unit 26 functions as a notification necessity determination unit in the claims. Specifically, the wireless device-side control unit 26 refers to the correspondence table stored in the memory 22 based on the information type identifier, and obtains information on necessity of notification corresponding to the information type identifier. The correspondence table stores a correspondence table in which AID and information on necessity of notification are associated with each other and data ID and information on necessity of notification are associated with each other. To do.

  Specific examples include information necessary for safe driving of vehicles such as obstacle information, road surface information such as snow and freezing, accident location information, road regulation information, traffic jam information, and signal information (hereinafter referred to as important information). ) Is associated with information indicating the necessity of notification among the information on necessity of notification, and information (hereinafter referred to as “comfort information”) such as facility information other than important information and event information of nearby stores, etc. , Referred to as auxiliary information) is associated with information indicating that notification is not necessary, among the information on necessity of notification. Therefore, when the information type identifier is an AID indicating a communication service application that transmits important information or a data ID indicating important information, information indicating the necessity of notification is obtained by the above-mentioned reference, The radio side controller 26 determines that notification is necessary. In addition, when the information type identifier is an AID indicating a communication service application that transmits auxiliary information or a data ID indicating auxiliary information, information indicating that notification is not necessary is obtained by the above-described reference, and the notification is performed. Is determined by the radio device-side control unit 26.

  When the information type identifier is important information, the radio device side control unit 26 determines that notification is necessary, and transmits the operation policy related information as the notification content to the external connection device 3. The external connection device 3 is instructed to cause the external connection device 3 to perform notification according to the operation policy related information (hereinafter referred to as a notification instruction). Therefore, the wireless device side control unit 26 and the wireless device side external I / F 25 function as an information transmission unit in the claims.

  Moreover, the connected device side control part 33 which received the notification instruction while receiving the operation policy related information temporarily cancels the function restriction mode when the function restriction mode is set, and receives the operation policy related information. The notification indicating this is performed by displaying a screen on the display of the connected device side HMI 32 or turning on an LED, or by outputting sound from the speaker of the connected device side HMI 32. Therefore, the connected device side control unit 33 and the connected device side external I / F 31 function as an information receiving unit in the claims. Furthermore, the connected device side control unit 33 that receives the operation policy related information and receives the notification instruction displays a guidance screen or a warning screen according to the operation policy related information on the display of the connected device side HMI 32 or the operation policy related information. Information notification is performed such that a guidance voice or a warning voice according to the information is output from the speaker of the connected device side HMI 32. Therefore, the connected device side HMI 32 functions as a notification unit, a display unit, and an audio output unit. The release of the function restriction mode may be temporarily performed only during notification according to the operation policy related information.

  When the information type identifier is not important information (that is, auxiliary information), the wireless device side control unit 26 determines that the notification is not necessary, and the notification by the connected device side HMI 32 is performed. Do not do.

  Each time the operation unit related information distributed from the roadside device 1 is received by the wireless unit 21 of the in-vehicle wireless device 2, the wireless device side control unit 26 requests the externally connected device 3 to confirm the setting, and the connected device. It is good also as a structure which receives the response containing the information of mode setting from the side control part 33. FIG. In this case, the mode setting latest information obtained from the connected device side control unit 33 may be overwritten in the RAM of the wireless device side control unit 26 to update the mode setting information.

  In the present embodiment, the configuration in which the correspondence table is stored in the memory 22 in advance is shown, but the present invention is not necessarily limited thereto. For example, the correspondence relationship table may be stored in advance in the ROM or RAM of the wireless device side control unit 26.

  According to the above configuration, when the in-vehicle wireless device 2 receives the operation policy related information distributed from the roadside device 1 outside the vehicle, the notification according to the operation policy related information is performed according to the type of the operation policy related information. Since it is possible to perform or not, it is possible to selectively perform only the notification according to the operation policy related information that is highly necessary for the driver among the operation policy related information distributed from the roadside machine 1 become. As a result, by not performing notification according to the operation policy related information that is less necessary for the driver, it is possible to make it difficult for the driver to feel annoying and to further improve the driver's comfort.

  In addition, the situation where the notification function is restricted such that the externally connected device 3 is set to the manner mode, for example, is a situation where the driver is restricting notification or operation because of driving, There may be situations where you want to drive in a quiet environment. However, even in such a situation, it is necessary to forcibly notify the information necessary for safe driving of the vehicle and important information that is highly necessary for the driver as a minimum necessary notification. Conceivable. On the other hand, the situation where the notification function is not restricted, for example, the external device 3 is not set to the manner mode or the drive mode is, for example, a request that the driver is stopped or the driver wants to drive in a quiet environment. The situation may be low. Therefore, in such a situation, it is considered that there is little risk of impairing the driver's comfort even if notification of auxiliary information that is less necessary for the driver is performed.

  According to the above configuration, even in the manner mode setting or the drive mode setting in which the notification function of the external connection device 3 is restricted by the connection device side control unit 33, the notification is performed by the radio device side control unit 26. When it is determined that it is necessary to perform the operation, the manner mode setting and the drive mode setting are canceled and the connected device-side HMI 32 display and speaker are notified, so the manner mode setting and the drive mode setting are performed. Even if the notification function is limited by the above, it is possible to perform the minimum necessary notification. In addition, according to the above configuration, it is possible to prevent notification according to the operation policy related information that is less necessary for the driver, and thus it is possible to make it difficult for the driver to feel troublesome. . Furthermore, according to the above configuration, in the case of the normal mode setting in which the notification function is not limited by the connected device side control unit 33, the radio side control unit 26 does not determine whether notification is necessary, and the roadside device When the notification according to the operation policy related information distributed from 1 is performed on the display or speaker of the connected device-side HMI 32, there is little risk of impairing the driver's comfort even if information that is less necessary for the driver is notified. Only in this case, it is possible to report information that is less necessary for the driver.

  In the present embodiment, the in-vehicle wireless device 2 determines whether or not notification is required according to the type of the operation policy related information distributed from the roadside device 1, and determines that it is necessary to perform notification. In this case, the notification itself has been shown to be performed in the external connection device 3 connected to the in-vehicle wireless device 2, but this is not necessarily limited thereto. For example, transmission of the operation policy related information distributed from the roadside device 1 to the externally connected device 3 is performed in the in-vehicle wireless device 2, determination of necessity of notification according to the type of the operation policy related information, and notification are performed. It is good also as a structure which performs the alerting | reporting at the time of determining that it is necessary in the external connection apparatus 3. FIG.

  Hereinafter, the flow of data among the roadside device 1, the in-vehicle wireless device 2, and the external connection device 3 in the other embodiment will be described with reference to FIG. FIG. 3 shows an example in which the system includes an external connection device that can communicate with the in-vehicle wireless device. FIG. 3 is an example of a sequence diagram showing a data flow among the roadside device 1, the in-vehicle wireless device 2, and the external connection device 3. Here, the following description will be made assuming that the roadside device 1 and the in-vehicle wireless device 2 are in a positional relationship in which communication is possible. Also here, the following description will be made assuming that the externally connected device 3 exists in the host vehicle and the in-vehicle wireless device 2 and the externally connected device 3 are in a connectable state. Note that data exchange between the in-vehicle wireless device 2 and the external connection device 3 is performed via the wireless device side external I / F 25 and the connection device side external I / F 31. Give an explanation. In this embodiment, it is assumed that the above-described correspondence table is stored in a memory (not shown) of the external connection device 3 instead of the memory 22 of the in-vehicle wireless device 2. Note that the memory of the externally connected device 3 mentioned here may be the same EEPROM or FLASH ROM as described above, or the ROM or RAM of the connected device side control unit 33.

  First, the wireless device side control unit 26 of the in-vehicle wireless device 2 performs polling (when the in-vehicle wireless device operates as a master device). Further, polling from the in-vehicle wireless device 2 is periodically repeated until a response to the polling is made from the external device 3. Note that the processing in the in-vehicle wireless device 2 is started, for example, when power is supplied to the in-vehicle wireless device 2 and the in-vehicle wireless device 2 is activated.

  Subsequently, the connected device side control unit 33 of the external device 3 responds to polling from the in-vehicle wireless device 2 including a connection request. In response to this response, the wireless device side control unit 26 notifies the external device 3 that the connection has been completed.

  Thereafter, the operation policy related information including the information type identifier distributed from the roadside device 1 is transmitted to the external connection device 3 by the radio device side control unit 26 as the notification content. The delivery of the operation policy related information from the roadside machine 1 may be performed every predetermined time, or may be performed when the roadside machine 1 detects a vehicle.

  Subsequently, when the operation policy related information including the information type identifier transmitted from the in-vehicle wireless device 2 is received by the external connection device 3, the connected device side control unit 33 determines that the currently set mode is the normal mode. It is determined whether or not there is. When it is determined that the currently set mode is the normal mode, the connected device-side control unit 33 displays a notification indicating that the operation policy related information has been received, a screen display on the display of the connected device-side HMI 32, and an LED. Or by sound output from the speaker of the connected device side HMI 32. Further, the connected device side control unit 33 displays a guidance screen or warning screen according to the operation policy related information on the display of the connected device side HMI 32, or displays a guidance voice or warning sound according to the operation policy related information on the connected device side. The content notification to be output from the speaker of the HMI 32 is performed.

  Further, when it is not determined that the currently set mode is the normal mode (that is, when the currently set mode is the function restriction mode), the information type identifier included in the operation policy related information Accordingly, the connected device side control unit 33 determines whether notification is necessary. Therefore, the connected device side control unit 33 functions as a notification necessity determination unit in the claims. Specifically, the connected device side control unit 33 refers to the correspondence table stored in the memory of the externally connected device 3 based on the information type identifier, and obtains information on necessity of notification corresponding to the information type identifier. To determine whether notification is necessary.

  When the information type identifier is important information, the connected device side control unit 33 determines that notification is necessary. When the connected device side control unit 33 determines that notification is necessary, the connected device side control unit 33 temporarily cancels the function restriction mode when the function restriction mode is set. Thus, the notification indicating that the operation policy related information has been received is made by displaying the screen of the connected device-side HMI 32 on the screen or turning on the LED, or by outputting sound from the speaker of the connected device-side HMI 32. Further, the connected device side control unit 33 displays a guidance screen or warning screen according to the operation policy related information on the display of the connected device side HMI 32, or displays a guidance voice or warning sound according to the operation policy related information on the connected device side. The content notification to be output from the speaker of the HMI 32 is performed. The release of the function restriction mode may be temporarily performed only during notification according to the operation policy related information.

  If the information type identifier is not important information (that is, if it is auxiliary information), the connected device side control unit 33 determines that the notification is not required, and notifies the connected device side HMI 32 of the information type identifier. Do not do.

  Even with the above configuration, it is possible to perform notification according to the operation policy related information according to the type of the operation policy related information or not, so the operation policy related information distributed from the roadside machine 1 It is possible to selectively perform only the notification according to the operation policy related information that is highly necessary for the driver.
