  Therefore, the problem to be solved by the invention is that the phone book data stored in the mobile phone can be automatically acquired at a high frequency, and the acquisition processing of the phone book data is performed according to the model of the mobile phone. It is an object of the present invention to provide an in-vehicle hands-free call device that can be executed while maintaining a hands-free connection as much as possible depending on whether the model is a multi-connectable model or a single-connected model.

  According to the present invention, the feature configuration of the in-vehicle hands-free call device having the function of acquiring the telephone directory data from the mobile phone is a hands-free call for performing a hands-free call due to the vehicle being turned on. A hands-free connection unit for performing a hands-free connection process for connecting to the mobile phone using a free communication protocol; and a telephone book data transfer protocol for transferring the phone book data after completion of the hands-free connection process. A telephone directory data connection acquisition processing unit for executing a telephone directory data connection acquisition process for acquiring the telephone directory data by connecting to the mobile phone, and transferring the telephone directory data during connection using the hands-free communication protocol. If the connection using the protocol fails, the connection using the hands-free communication protocol is disconnected and then the telephone A re-acquisition processing unit that executes the data connection acquisition process again, and after the re-acquisition processing unit performs the connection process using the phone book data transfer protocol in the phone book data connection acquisition process, the hands-free connection process And a hands-free connection return unit to be executed again.

According to the above characteristic configuration, after the vehicle power is turned on, the user can automatically store the phone book data of the mobile phone without operating the on-vehicle hands-free call device or the mobile phone. Can be transferred to. Therefore, the hands-free function can be used by using the latest phone book data stored in the mobile phone, and the convenience for the user is improved.
Also, if the hands-free connection process and the phone book data connection acquisition process are executed at the same time, a processing load is imposed by the simultaneous process and the processing method becomes complicated. Therefore, in the case of this simultaneous processing, it may be considered that the completion of the hands-free connection processing is delayed. On the other hand, according to the above-described feature configuration, after the vehicle is turned on, the hands-free connection process is first executed. It can be in a state where can be performed. For example, even if the vehicle starts running immediately after the vehicle is turned on, the hands-free function can be used immediately after the vehicle is turned on. Safe driving is possible. On the other hand, the transfer of the phone book data takes a processing time proportional to the amount of data, but since the hands-free connection processing has already been completed, the transfer processing can be performed without worrying about the processing time. .

Furthermore, even if the mobile phone is a single connection model that cannot be connected using the phone book data transfer protocol at the same time during connection using the hands-free communication protocol, the hands-free communication protocol is used. The phone book data is automatically acquired after the vehicle is turned on because the phone book data acquisition process is performed by disconnecting the connection that has been disconnected. Can do.
In addition, according to the above-described feature configuration, even if the mobile phone is a single connection model, the hands-free connection is automatically performed after disconnecting the hands-free connection and performing the connection process using the telephone directory data transfer protocol. Can be recovered.

  Here, after the completion of the phone book data connection acquisition process by the re-acquisition processing unit, the hands-free connection return unit disconnects the connection using the phone book data transfer protocol and executes the hands-free connection process again. It is preferable to adopt a configuration to do so.

  Here, the in-vehicle hands-free call device includes an acquisition history determination unit that determines whether or not the phone book data has been acquired in the past after the completion of the hands-free connection process, When connected to a mobile phone that has acquired phone book data, the user can select whether or not to execute the phone book data connection acquisition process for the mobile phone and prompt the user to make the selection. A query processing unit that executes query processing for performing notification, and the telephone book data connection acquisition processing unit selects execution or cancellation of the phone book data connection acquisition processing according to a selection result in the query processing This is preferable.

According to this configuration, when the phone book data is connected to a mobile phone that has not been acquired in the past, the phone book data can be automatically acquired. It can suppress that the state where data cannot be acquired arises. Therefore, even a new mobile phone can use the hands-free function using the phone book data, and the convenience for the user is improved.
In addition, when the phone book data is connected to a mobile phone that has been acquired in the past, the user is allowed to select execution or cancellation of the phone book data connection acquisition process. Execution of the data connection acquisition process can be suppressed. In addition, since the inquiry process is automatically executed after the vehicle is turned on, user convenience is also ensured.
Since the determination of the past acquisition history is performed after the hands-free connection process is completed, the hands-free connection process can be preferentially performed, and the mobile phone information obtained by the hands-free connection can be used effectively. An acquisition history can be determined.

  Here, the in-vehicle hands-free communication device is configured to disconnect the connection using the hands-free communication protocol by the re-acquisition processing unit and complete the hands-free connection processing again by the hands-free connection return unit. In the meantime, it is preferable to further include a disconnection notification unit that notifies the user that the connection for performing a hands-free call is being disconnected in order to acquire the phonebook data.

  According to this configuration, it is possible to notify the user that the hands-free connection is being temporarily disconnected for the phone book data acquisition process. Therefore, it is possible to notify the user that the hands-free function cannot be used while the phone book data acquisition process is being performed.

  Here, the phone book data includes one or both of phone number data and call history data, and the in-vehicle hands-free call device determines whether or not the phone number data can be acquired in the phone book data connection acquisition process and the call. The phonebook data connection acquisition processing unit further includes an acquisition setting unit that allows the user to select one or both of history data acquisition availability and stores the selection setting, and the telephone directory data connection acquisition processing unit stores the selection stored by the acquisition setting unit. It is preferable that the telephone directory data connection acquisition process is executed according to the setting.

  According to this configuration, since the setting in which the user has selected whether or not to acquire telephone number data or whether or not to acquire call history data is stored, the acquisition of telephone number data or call history data is performed according to the user's selection result. It can be carried out. As a result, it is possible to execute an appropriate phone book data acquisition process according to the usage status of the mobile phone by the user. For example, a user whose telephone number data update frequency is low can reduce the amount of data transfer by setting the telephone number data not to be acquired. Even in this configuration, after the vehicle is turned on, the acquisition process of the telephone number data or call history data selected to be acquired is automatically executed, so that the convenience for the user is improved.

  The technical features of the in-vehicle hands-free call device according to the present invention having the above-described configurations can also be applied to a telephone directory data acquisition program and a telephone directory data acquisition method. Therefore, the present invention includes such a program. And methods can also be subject to rights.

In the first embodiment described above, after the hands-free connection return process by the hands-free connection return unit 34 is completed after the accessory power switch 4 of the vehicle is turned on, the telephone directory data connection acquisition processing unit 32 does not provide any conditions. Phone book data connection acquisition processing was being executed. However, in this embodiment, the control device 10 further determines whether or not the power-off period until the accessory power switch 4 of the vehicle is turned on is equal to or shorter than a predetermined setting period. And the phone book data connection acquisition processing unit 32 is different from the execution of the phone book data connection acquisition processing after the hands-free connection processing is completed when the power-off period is equal to or shorter than the set period. The configuration of the in-vehicle hands-free communication device 1 is different from that of the first embodiment in that it further includes a power-off period determination unit in the control device 10, but the other components are the same as those in FIG. Below, the control apparatus 10 which concerns on this embodiment is demonstrated centering on difference with said 1st embodiment. Note that points not particularly described are the same as those in the first embodiment.

  The power-off period determination unit performs a process of determining whether or not a power-off period, which is a period in which the power is off until the accessory power switch 4 of the vehicle is turned on, is equal to or less than a predetermined setting period. It is a functional part. More specifically, the control device 10 has a timer function that operates with a backup power supply while the accessory power switch 4 of the vehicle is turned off, and the power-off period determination unit includes the accessory power switch of the vehicle. After 4 is turned on, the power-off period is calculated based on the time measured by the timer function. Then, the power-off period determination unit determines whether or not the calculated power-off period is equal to or less than a predetermined setting period. For example, the setting period can be a period set between 30 seconds and 10 minutes so as to correspond to a period in which the user turns off the accessory power switch 4 of the vehicle for idle stop. The setting period may be a fixed period, but may be configured so that the user can change it from a setting menu or the like.
