本发明涉及车辆内可能支援的服务的显示系统及方法，尤其是在联动运用车辆头部单元与便携式机器时通过Wi-Fi搜索的车辆内可能支援的服务显示系统及方法。The present invention relates to a display system and method of services that may be supported in a vehicle, especially a system and method for displaying services that may be supported in a vehicle through Wi-Fi search when the vehicle head unit and a portable device are used in conjunction.
背景技术Background technique
随着诸如智能手机等使用者的便携式机器的性能急剧提高，且在便携式机器运用的各种应用程序被开发，大大扩大了便携式机器的使用区域。As the performance of users' portable devices such as smartphones has been rapidly improved, and various applications for use in the portable devices have been developed, the use area of the portable devices has been greatly expanded.
另外，现在在大部分的车辆具备了由头部单元(HeadUnit)控制的车辆用音频/视频/导航(AVN)等，并且设置用于显示在AVN输出的影像的车辆用显示器。另外，车辆用显示器提供比便携式机器大的画面。In addition, most vehicles are currently equipped with a vehicle audio/video/navigation (AVN) controlled by a head unit (HeadUnit), and are provided with a vehicle display for displaying images output from the AVN. In addition, a display for a vehicle provides a larger screen than that of a portable device.
据此，现在车辆的头部单元提供与便携式机器的有线或无线连接服务，以使车辆乘坐者能够在车辆内便利地使用在便携式机器提供的各种应用程序。在其中，尤其是利用Wi-Fi(WirelessFidelity，无线)的连接，因其诸如无线的便利性及与多个装置连接的便利性及大容量数据传输的优点，正在扩大其适用范围。Accordingly, a head unit of a vehicle now provides a wired or wireless connection service with a portable device, so that a vehicle occupant can conveniently use various applications provided in the portable device in the vehicle. Among them, in particular, connection using Wi-Fi (Wireless Fidelity, wireless) is expanding its scope of application due to its advantages such as wireless convenience, convenience of connecting with multiple devices, and large-capacity data transmission.
Wi-Fi为，一般以AP(AccessPoint，无线接入点)为基准Wi-Fi机器执行通信，在车辆执行Wi-Fi通信的情况下，通常头部单元执行AP的功能。但是，在最近作为Wi-Fi为基础的新通信技术Wi-FiDirect正在被频繁使用。Wi-FiDirect无需单独的AP而是Wi-Fi机器分别执行AP的功能进行相互直接通信。尤其是，在限定的空间内执行通信的车辆内机器之间的通信中能够更加有效地利用Wi-FiDirect。另外，以Wi-FiDirect技术为基础强化多媒体传送技术的Miracast也是受到瞩目的新技术。Wi-Fi generally uses AP (Access Point, wireless access point) as a reference for Wi-Fi equipment to perform communication. When the vehicle performs Wi-Fi communication, the head unit usually performs the function of AP. However, recently, Wi-Fi Direct, which is a new communication technology based on Wi-Fi, is being frequently used. Wi-Fi Direct does not require a separate AP, but Wi-Fi machines perform the functions of APs to communicate directly with each other. In particular, Wi-Fi Direct can be more effectively utilized in communication between in-vehicle devices that perform communication within a limited space. In addition, Miracast, which strengthens multimedia transmission technology based on Wi-FiDirect technology, is also a new technology that has attracted attention.
随着扩大以Wi-Fi为基础的车辆内机器的通信连接，车辆内机器尤其是在使用者的便携式机器与车辆头部单元之间通过Wi-Fi或Wi-Fidirect连接提供的服务或应用程序的种类也变得多样起来。以Wi-Fi为基础连接头部单元与便携式机器使用的代表性的服务有诸如DLNA(DigitalLivingNetworkAlliance，数字生活网络联盟)、CarPlay、AndroidAuto、车联网(MirrorLink)的镜像技术。With the expansion of Wi-Fi-based in-vehicle equipment communication connections, in-vehicle equipment, especially services or applications provided by Wi-Fi or Wi-Fidirect connections between the user's portable equipment and the vehicle head unit types have also become diverse. Typical services used to connect the head unit and portable devices based on Wi-Fi include mirroring technologies such as DLNA (Digital Living Network Alliance), CarPlay, Android Auto, and MirrorLink.
图1是示出现有技术的基于Wi-Fi连接车辆头部单元与便携式机器时显示的画面的一示例。FIG. 1 shows an example of a screen displayed when a vehicle head unit and a portable device are connected by Wi-Fi in the related art.
如图1所示，就算在现有技术中利用头部单元与便携式机器之间的Wi-Fi或Wi-Fidirect连接的服务或应用程序的种类变得多样，但是在现有技术中只有能够连接的机器的名字与保安类型及信号强度显示于头部单元的显示器或便携式机器的显示部。因此，存在很难识别使用者能够使用的服务的问题。不仅如此，就算使用者能够识别可能使用的服务，也必须将用于使用该功能的设定全部输入于头部单元与便携式机器双方，因此存在使用不便的问题。As shown in FIG. 1 , even though the types of services or applications that utilize Wi-Fi or Wi-Fidirect connection between the head unit and the portable device become diverse in the prior art, only The name of the machine, security type and signal strength are displayed on the display of the head unit or the display part of the portable machine. Therefore, there is a problem that it is difficult to identify services that can be used by the user. Moreover, even if the user can recognize the service that can be used, all the settings for using the function must be input to both the head unit and the portable device, so there is a problem of inconvenience in use.
韩国公开专利第10-2012-0039894号“车辆头部单元与智能手机联动系统及方法”记载了作为便携式机器的智能手机与车辆头部单元之间连动应用程序的技术，但是其技术是车辆头部单元连接于在智能手机提供的web服务器，通过车辆头部单元显示与智能手机相同的画面的镜像技术，并且无法使使用者容易地识别便携式机器与头部单元能够提供的服务。Korean Laid-Open Patent No. 10-2012-0039894 "System and Method for Linking Vehicle Head Unit and Smartphone" describes a technology for linking applications between a smartphone and a vehicle head unit as a portable device, but its technology is not The head unit is connected to the web server provided in the smartphone, and the vehicle head unit displays the same screen as the mirroring technology of the smartphone, and the user cannot easily identify the services that the portable device and the head unit can provide.

At least one user terminal 200 replies respectively to the header unit 200 in the provider item of the probe response packet including the provider information and the service name possibly implemented in the probe request packet, and the header unit 200 receives from the at least one user terminal The 200 respectively receives the probe response packet (S40).
图4是示出探测请求数据包的构成。FIG. 4 shows the configuration of a probe request packet.
如上所述图4示出的探测响应数据包的构成被指定为Wi-Fi规格(IEEE802.11)，并且包括1byte(比特，字节)的VendorSpecific(特定供应商)项目与1byte的Length(长度)项目、3byte的Vendor(供应商)项目及1byte的Type(类型)项目。本发明为使至少一个使用者终端100分别在上述3byte的供应商项目包括在探测请求数据包施加的供应商数据和可能施行的服务名称来分别传送到头部单元200，进而可使头部单元200识别可能施行的服务。As mentioned above, the configuration of the probe response packet shown in FIG. 4 is specified as the Wi-Fi specification (IEEE802.11), and includes a 1byte (bit, byte) VendorSpecific (vendor specific) item and a 1byte Length (length ) item, 3byte Vendor (supplier) item and 1byte Type (type) item. The present invention is to make at least one user terminal 100 respectively transmit the provider data and the service name that may be implemented in the above-mentioned 3byte provider item included in the probe request data packet to the head unit 200, and then the head unit can 200 identifies possible services to perform.
在这里，至少一个使用者终端100不包括将被使用者设定为非激活的服务于探测响应数据包。即，被使用者设定为未在至少一个的使用者终端100使用的应用程序的服务不被传送到头部单元200。Here, at least one user terminal 100 does not include a service probe response packet to be set inactive by the user. That is, the service of the application program set by the user not to be used on at least one user terminal 100 is not transmitted to the head unit 200 .
在本发明中至少一个使用者终端100将包括供应商信息和可能施行的服务名称的探测响应数据包传送到头部单元200，这是因为不仅能够按照各个使用者终端100制造商分别支援相互不同的服务，还不同地设定了施行各个服务的方法及菜单名称等。即，按照各个制造商分别不同地设定Wi-Fi服务的施行规格，并且使用者已经适应自身的使用者机器，因此若显示与使用者终端100中的形式不同的形态，则存在使用者很难使用该服务的问题。In the present invention, at least one user terminal 100 transmits a probe response data packet including provider information and possibly implemented service names to the head unit 200, because not only can each user terminal 100 manufacturer support different For each service, the method of executing each service, menu name, etc. are also set differently. That is, the implementation specifications of Wi-Fi services are set differently for each manufacturer, and the user has already adapted to his own user device, so if a form different from that in the user terminal 100 is displayed, there is a possibility that the user may have difficulty. Difficulty using the service.
据此，在本发明中至少一个使用者终端100分别在探测响应数据包直接包括自身提供的服务名称，并分别将探测响应数据包传送到头部单元200，进而可使使用者容易地选择所需的服务。Accordingly, in the present invention, at least one user terminal 100 directly includes the service name provided by itself in the probe response data packet, and transmits the probe response data packet to the head unit 200 respectively, so that the user can easily select the required services.
若从至少一个使用者终端100分别接收探测响应数据包，则头部单元200分析接收到的探测响应数据包来获取包括于供应商项目的至少一个服务名称。然后，利用已获取的服务名称与使用者终端的信息来构成服务目录(S60)，其中使用者终端的信息包括于对应于各个服务的VendorSpecific(特定供应商)项目。If the probe response data packets are respectively received from at least one user terminal 100 , the head unit 200 analyzes the received probe response data packets to obtain at least one service name included in the provider item. Then, construct a service catalog (S60) by using the acquired service name and user terminal information, wherein the user terminal information includes VendorSpecific (vendor specific) items corresponding to each service.
这时，头部单元200对于由Wi-Fi设定而非激活的服务并不包括在服务目录。即，就算是作为可能在至少一个使用者终端100使用的服务而传输的服务，只要在Wi-Fi设定中设定为未使用的服务则不包括于服务目录，进而增大了使用者的使用便利性。At this time, the head unit 200 is not included in the service list for services that are not activated by Wi-Fi settings. That is, even if it is a service transmitted as a service that may be used by at least one user terminal 100, as long as it is set as an unused service in the Wi-Fi setting, it will not be included in the service list, thereby increasing the user's security. Ease of use.
在上述中说明了头部单元200在探测请求数据包的供应商项目(Vendor)包括可能施行Wi-Fi的服务信息请求来传送探测请求数据包，但是在本发明中头部单元也可在供应商项目(Vendor)一起包括AP状态请求并进行传送。在这里，AP状态请求信号意味着能够与头部单元200连接的至少一个使用者终端100或头部单元200待执行通信的AP各个的状态信息。It has been explained above that the head unit 200 transmits the probe request data packet when the vendor item (Vendor) of the probe request data packet includes a Wi-Fi service information request, but in the present invention, the head unit can also The AP status request is included together with the vendor item (Vendor) and transmitted. Here, the AP status request signal means at least one user terminal 100 connectable to the head unit 200 or status information of each of the APs with which the head unit 200 is to perform communication.
如果头部单元200在传送探测请求数据包的供应商项目时一起传送AP状态请求，则至少一个使用者终端100或AP不仅是可施行的服务还将AP状态信息包括于探测响应数据包的供应商项目。在这里，在AP状态信息可包括现在至少一个的使用者终端100各个的数据处理量、连接于现在的至少一个使用者终端100或AP使用数据的终端的个数、相同频道上的AP个数、周边频道的AP个数及AP的信号强度等，来传送AP状态信息。If the header unit 200 transmits the AP status request together with the provider item of the probe request packet, at least one user terminal 100 or AP is not only serviceable but also includes the AP status information in the supply of the probe response packet. business project. Here, the AP status information may include the current data processing capacity of at least one user terminal 100, the number of terminals connected to the current at least one user terminal 100 or AP using data, and the number of APs on the same channel. , the number of APs in the surrounding channels and the signal strength of the AP, etc., to transmit the AP status information.
在这里，相同频道上的AP个数、周边频道的AP个数是因为可能在Wi-Fi通信中产生无线干涉而确认的，而AP的信号强度是因为信号强度越好则能够降低数据包的错误率而确认的。Here, the number of APs on the same channel and the number of APs on neighboring channels are confirmed because wireless interference may occur in Wi-Fi communication, and the signal strength of APs is because the better the signal strength, the lower the packet loss. Confirmed by the error rate.
据此，若在探测响应数据包包括AP状态信息并传送该探测响应数据包，则头部单元200分析已传送的AP状态(S70)。头部单元200在分析AP状态时在AP信息中根据影响数据使用的程度给各个信息分配优选顺序并可用分数来数值化。Accordingly, if the probe response packet includes AP status information and the probe response packet is transmitted, the head unit 200 analyzes the transmitted AP status (S70). When analyzing the AP state, the head unit 200 assigns a priority order to each piece of information in the AP information according to the degree of impact on data usage, and can be quantified with a score.
只是，与构成服务目录的情况相同，若在分析AP状态时由使用者设定而存在不使用的AP，则头部单元200可将该AP在分析对象中除外。However, as in the case of configuring the service list, if there is an unused AP set by the user when analyzing the AP status, the head unit 200 can exclude the AP from the analysis object.
之后，头部单元200将已构成的服务目录与AP状态显示于界面部210(S80)。即，头部单元200与现有技术不同不仅显示信号的强度，还可将使用者能够利用的服务与该机器的AP状态显示给使用者。另外，若使用者选择已显示的服务目录中的一个或选择AP状态，则向对应的使用者终端100传送服务施行请求或连接请求来执行已选择的服务，或与该使用者终端连接。Afterwards, the head unit 200 displays the configured service list and AP status on the interface unit 210 ( S80 ). That is, unlike the prior art, the head unit 200 not only displays the strength of the signal, but also displays the services available to the user and the AP status of the device to the user. In addition, when the user selects one of the displayed service lists or selects the AP status, a service execution request or a connection request is sent to the corresponding user terminal 100 to execute the selected service or connect to the user terminal.
在上述中说明了头部单元200将可能施行Wi-Fi的服务信息请求与AP状态请求一同包括于探测请求数据包的项目并传送该探测请求数据包，并接收包括服务名称与AP状态信息的探测响应数据包，但是在这一情况，在探测请求数据包或探测响应数据包的规格也可无需包括所有信息。据此，头部单元200区分可能施行Wi-Fi的服务信息请求与AP状态请求并进行个别传送，并且也可区分地接收分别对应的服务名称与AP状态信息。It has been described above that the header unit 200 includes the service information request that may implement Wi-Fi together with the AP status request in the probe request packet, transmits the probe request packet, and receives the service name and AP status information. Probe Response packet, but in this case, it is also unnecessary to include all information in the specification of the Probe Request packet or the Probe Response packet. Accordingly, the head unit 200 distinguishes the service information request that may implement Wi-Fi and the AP status request and transmits them separately, and can also separately receive the corresponding service name and AP status information.
图5是示出根据本发明的基于Wi-Fi连接头部单元与便携式机器时显示的画面的一示例。图6是示出在选择服务时在头部单元显示的画面的一示例。FIG. 5 shows an example of a screen displayed when a head unit and a portable device are connected by Wi-Fi according to the present invention. FIG. 6 shows an example of a screen displayed on the head unit when a service is selected.
图5为简单的一示例，示出了头部单元200与现有技术的信号强度一同显示可能给使用者提供的Wi-Fi服务名称的构成。与图1比较时，使用者能够视觉确认各个使用者终端100能够提供的服务，因此易于选择特定使用者终端。不仅如此，如图6所示使用者选择特定服务，进而无需另外的设定使该服务即显示于头部单元200，因此可将使用的服务使用便利性极大化。FIG. 5 is a simple example showing the structure of the head unit 200 displaying the name of the Wi-Fi service that may be provided to the user together with the signal strength of the prior art. Compared with FIG. 1 , the user can visually confirm the services that can be provided by each user terminal 100 , so it is easy to select a specific user terminal. Not only that, as shown in FIG. 6 , the user selects a specific service, and the service is displayed on the head unit 200 without additional settings, so the convenience of using the service can be maximized.
根据本发明的方法可实现为在能够由电脑读取的记录媒体能够由电脑读取的代码。电脑能够读取的记录媒体包括保存能够被电脑系统读取的数据的所有种类的记录装置。例如，记录媒体有ROM、RAM、CD-ROM、磁带、软盘、光学数据存储设备等，并且也包括实现载波(例如，通过网络传送)的形态。并且，电脑能够读取的记录媒体被分散于由网络连接的电脑系统，并且能够以分散方式保存并施行电脑能够读取的代码。The method according to the present invention can be implemented as computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all kinds of recording devices that store data that can be read by a computer system. For example, the recording medium includes ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage device, etc., and also includes a form that realizes carrier waves (for example, transmission through a network).
