The applicationprogramming interface server 128 is used for parsing the command packet to identify whether the packet content of the command packet conforms to the service request.

参阅图3所示，车载信息处理方法包含下列步骤。Referring to FIG. 3 , the in-vehicle information processing method includes the following steps.

首先，车载设备单元120的应用程序通信接口122经由配对程序与手持装置200配对，而建立应用程序通信频道AP，如步骤S110所述。此一步骤主要是通过应用程序通信接口122，让车载设备单元120与手持装置200建立点对点(P2P)的专属通信链接。First, theapplication communication interface 122 of the in-vehicle equipment unit 120 is paired with thehandheld device 200 via the pairing procedure to establish the application communication channel AP, as described in step S110. In this step, the in-vehicle equipment unit 120 and thehandheld device 200 are mainly established through the applicationprogram communication interface 122 to establish a dedicated peer-to-peer (P2P) communication link.

同时或接续步骤S110，车载设备单元120通过控制请求转送模块124与车辆部件控制单元110建立通信连接，如步骤S120所示。车辆部件控制单元110的具体实施态样如前所述，车辆部件控制单元110用以接收控制请求，以依据控制请求执行车辆平台的部件X、Y的控制作业。At the same time or following step S110, the in-vehicle equipment unit 120 establishes a communication connection with the vehiclecomponent control unit 110 through the control request transfer module 124, as shown in step S120. The specific implementation of the vehiclecomponent control unit 110 As described above, the vehiclecomponent control unit 110 is used for receiving a control request, so as to execute the control operation of the components X and Y of the vehicle platform according to the control request.

同时或接续步骤S120，车载设备单元120启动一或多个应用服务A、B、C、D，且每一应用服务A、B、C、D响应于对应的服务请求，如步骤S130所示。如图2所示，服务请求是由服务请求模块220、230、240、250依据用户对手持装置200的操作产生，每一个服务请求模块220、230、240、250对应于一个应用服务A、B、C、D，例如服务请求模块220对应于应用服务A，而服务请求模块230对应于应用服务B，服务请求模块240对应于应用服务C，而服务请求模块250对应于应用服务D。At the same time or following step S120, the in-vehicle equipment unit 120 starts one or more application services A, B, C, D, and each application service A, B, C, D responds to the corresponding service request, as shown in step S130. As shown in FIG. 2, the service request is generated by theservice request modules 220, 230, 240, 250 according to the user's operation on thehandheld device 200, and eachservice request module 220, 230, 240, 250 corresponds to an application service A, B , C, D, for example, service request module 220 corresponds to application service A,service request module 230 corresponds to application service B, service request module 240 corresponds to application service C, andservice request module 250 corresponds to application service D.

手持装置200依据所执行的应用程序模块，产生并发出指令封包，所述指令封包可包含服务请求或控制请求其中之一。车载设备单元120接收手持装置200发出的指令封包，并以应用程序执行模块126比对指令封包的封包内容是否符合服务请求，如步骤S140及步骤S150所示。Thehandheld device 200 generates and sends an instruction packet according to the executed application program module, and the instruction packet may include one of a service request or a control request. The in-vehicle equipment unit 120 receives the command packet sent by thehandheld device 200, and uses the application program execution module 126 to compare whether the packet content of the command packet conforms to the service request, as shown in step S140 and step S150.

指令封包可以用列表方式，呈现内容，例如以下表一的范例：The command packet can be presented in the form of a list, such as the following example in Table 1:

表一Table I

类别字段指定对应的应用服务A、B、C、D，作业字段则为应用服务A、B、C、D的功能，例如于显示信息时，显示信息所要用到的字段。接口形式关联于功能，例如开/关的切换或数值的输入，用于确认输入值形式是否正确。输入值关联于所要执行的作业，例如执行特定功能的开/关的切换时，输入值为TRUE/FALES，执行特定功能数值调整时，输入值为数字。横向字段可以通过脚本，例如JSON语言依序写入文字指令及输入值成为指令封包。当然指令封包也会包含装置标识符或联机授权码等用于建立P2P通信所需要的信息。The category field specifies the corresponding application services A, B, C, and D, and the job field is the functions of the application services A, B, C, and D, such as the fields used to display the information when displaying information. The interface form is associated with a function, such as on/off switching or the input of a value, and is used to confirm whether the input value form is correct. The input value is associated with the job to be performed, for example, when performing the on/off switch of a specific function, the input value is TRUE/FALES, and when performing the numerical adjustment of a specific function, the input value is a number. Horizontal fields can be written into text commands and input values sequentially through scripts, such as JSON language, into command packets. Of course, the command packet will also contain information required for establishing P2P communication, such as a device identifier or a connection authorization code.

应用程序执行模块126接收指令封包，解析封包内容的字段并逐一与如表一的列表比对。例如，指令封包的封包内容依序为应用服务A、来电显示、开启来电显示提醒、车款A、TRUE时，就可以确认指令封包此一指令封包包含来自手持装置200的服务请求。The application execution module 126 receives the instruction packet, parses the fields of the packet content and compares them with the list in Table 1 one by one. For example, when the packet contents of the command packet are application service A, caller ID, caller ID alert on, car model A, and TRUE in sequence, it can be confirmed that the command packet contains the service request from thehandheld device 200 .

若指令封包封包内容标头(类别)没有对应的应用服务A、B、C、D，或完整封包内容不在列表中，则判断此一指令封包不包含正确的服务请求。指令封包不包含正确的服务请求的情况包含封包格式错误(指令封包与服务请求无关)、对应的应用程序服务未启用、作业错误、不适用于当前车辆平台、输入值错误等。If the content header (category) of the command packet has no corresponding application service A, B, C, or D, or the complete packet content is not in the list, it is determined that the command packet does not contain a correct service request. The case where the command packet does not contain the correct service request includes the packet format error (the command packet has nothing to do with the service request), the corresponding application service is not enabled, the operation is wrong, does not apply to the current vehicle platform, the input value is wrong, etc.

如图3所示，当指令封包符合服务请求，例如符合表一第一列字段至第四列字段其中之一，应用程序执行模块126依据服务请求执行应用服务A、B、C、D，并以应用程序通信接口122通过应用程序通信频道AP提供应用服务A、B、C、D，如步骤S160所示。As shown in FIG. 3 , when the instruction packet conforms to the service request, for example, conforms to one of the fields in the first column to the fourth column of Table 1, the application program execution module 126 executes the application services A, B, C, and D according to the service request, and The application services A, B, C, and D are provided by theapplication communication interface 122 through the application communication channel AP, as shown in step S160.

以表一的第一列字段为例，当做为手持装置200的智能型手机接到来电，其来电显示程序(服务请求模块220)就会发出来电显示的服务请求，通过联机管理模块210发送至应用程序执行模块126。应用程序执行模块126则启用来电显示的应用服务A，接着驱动触控显示手段显示有来电。手持装置200会持续发出不同的服务请求，包含来电号码以及免持听筒联机请求等等，这些服务请求可能由其他的服务请求模块230产生，而要求其他的应用服务。此时，触控显示手段就会持续显示来电号码以及是否免持听筒接听的信息。前述的服务请求都与智能型手机的电话功能有关，例如应用服务A涉及了智能型手机的来电显示是否开启，应用服务B则涉及了智能型手机来电的免持听筒自动接听功能是否开启。Taking the fields in the first column of Table 1 as an example, when the smart phone as thehandheld device 200 receives an incoming call, its caller ID program (service request module 220) will send out a caller ID service request, which is sent to the caller ID through theonline management module 210. The application executes the module 126 . The application execution module 126 enables the application service A of the caller display, and then drives the touch display means to display the caller. Thehandheld device 200 will continue to send out different service requests, including the incoming call number and the speakerphone connection request, etc. These service requests may be generated by otherservice request modules 230 and require other application services. At this time, the touch display means will continuously display the caller number and information on whether the speaker is answering. The aforementioned service requests are all related to the phone function of the smartphone. For example, application service A involves whether the caller ID of the smartphone is turned on, and application service B involves whether the automatic answering function of the hands-free handset for incoming calls from the smartphone is turned on.

应用程序执行模块126也会通过应用程序通信频道AP发出手持装置控制请求，以取得手持装置200的联机控制权限，并通过应用程序通信频道AP接收一手持装置控制响应。例如于前述的例子中，若用户由手持装置200启用应用服务B而开启免持听筒的自动接听，应用程序执行模块126就会响应免持听筒自动接听的服务请求，取得手持装置200的联机控制权限，而将手持装置200的电话通信连接至应用程序执行模块126，再由应用程序执行模块126驱动必要的硬件执行免持听筒作业。The application execution module 126 also sends a handheld device control request through the application communication channel AP to obtain the connection control authority of thehandheld device 200, and receives a handheld device control response through the application communication channel AP. For example, in the aforementioned example, if the user activates the application service B from thehandheld device 200 to enable the automatic answering of the hands-free handset, the application execution module 126 will respond to the service request of the automatic answering of the hands-free handset, and obtain the online control of thehandheld device 200 permission, and the telephone communication of thehandheld device 200 is connected to the application program execution module 126, and then the application program execution module 126 drives necessary hardware to perform the speakerphone operation.

另一种情况是通过车载设备单元120显示手持装置200上的特定信息，例如手持装置200的电量图标以及电量数值。此时，用户先通过应用程序C发出如表一的第三列字段的服务请求封包之后(输入值为TRUE)，应用程序执行模块126提供应用服务C的方式就会包含通过应用程序通信频道AP发出一指定信息的信息请求指令至手持装置200，要求手持装置200回传指定信息(手持装置200的电量图标以及电量数值)，使得应用程序执行模块126由应用程序通信频道AP接受指定信息的响应以显示指定信息。同时，为了持续更新手持装置200的电量图标以及电量数值，提供应用服务C的方式还包含应用服务C定时重复发出信息请求指令，并接受指定信息(更新的手持装置200的电量图标以及电量数值)的响应，以更新所显示的指定信息。或者，手持装置200直接周期地发出服务请求，并使服务请求包含指定信息，使得应用程序执行模块126直接响应以显示指定信息，并持续地更新。应用程序执行模块126也可以是单纯的取得手持装置200的联机控制权限；用户由手持装置200启用应用服务D，应用程序执行模块126就会响应手机屏幕开关的服务请求，取得手持装置200的联机控制权限，并以触控显示手段显示开/关图标，让用户可以从车载信息装置120的触控显示手段对手机屏幕进行开关。Another situation is to display specific information on thehandheld device 200 through the in-vehicle equipment unit 120 , such as the battery icon and the battery value of thehandheld device 200 . At this time, after the user first sends the service request packet as shown in the third column of Table 1 through the application C (the input value is TRUE), the way in which the application execution module 126 provides the application service C includes the communication channel AP through the application program Sending an information request command of specifying information to thehandheld device 200, requesting thehandheld device 200 to return the specified information (the battery icon and the battery value of the handheld device 200), so that the application execution module 126 receives the response of the specified information through the application communication channel AP to display the specified information. At the same time, in order to continuously update the power icon and power value of thehandheld device 200, the method of providing the application service C further includes that the application service C periodically repeatedly sends out an information request command, and accepts the specified information (updated power icon and power value of the handheld device 200). response to update the specified information displayed. Alternatively, thehandheld device 200 directly issues the service request periodically, and makes the service request include the specified information, so that the application program execution module 126 directly responds to display the specified information, and continuously updates. The application execution module 126 can also simply obtain the online control authority of thehandheld device 200; the user activates the application service D from thehandheld device 200, and the application execution module 126 responds to the service request of the mobile phone screen switch and obtains the connection of thehandheld device 200. Control authority, and display the on/off icon by touch display means, so that the user can switch the mobile phone screen from the touch display means of the in-vehicle information device 120 .

如图3及图4所示，当指令封包不符合服务请求，应用程序执行模块126进一步识别指令封包是否符合控制请求，如步骤S170所示。若指令封包符合控制请求，例如符合表一中第五列至第七列字段，应用程序执行模块126通过控制请求转送模块124传送控制请求至车辆部件控制单元110，使车辆部件控制单元110以控制请求执行部件控制作业，如步骤S180所示。As shown in FIG. 3 and FIG. 4 , when the command packet does not meet the service request, the application execution module 126 further identifies whether the command packet meets the control request, as shown in step S170 . If the command packet matches the control request, for example, matches the fields in the fifth column to the seventh column in Table 1, the application execution module 126 transmits the control request to the vehiclecomponent control unit 110 through the control request forwarding module 124, so that the vehiclecomponent control unit 110 can control the The execution of the component control job is requested, as shown in step S180.

若指令封包也不符控制请求，则应用程序执行模块126响应错误提示，例如指令不在列表列表中，并由应用程序通信频道AP传送回手持装置200，如步骤S190所示。If the command packet also does not match the control request, the application execution module 126 responds to an error prompt, eg, the command is not in the list, and transmits it back to thehandheld device 200 through the application communication channel AP, as shown in step S190.

回到步骤S180，以控制请求执行部件控制作业之后，车辆部件控制单元110会响应一控制结果，通过控制请求转送模块124、应用程序编程接口服务器128、应用程序通信接口122以及应用程序通信频道AP输出控制结果至手持装置200，如步骤S200所示。Returning to step S180, after executing the component control operation based on the control request, the vehiclecomponent control unit 110 responds with a control result, and transmits the control request through the control request transfer module 124, the applicationprogramming interface server 128, theapplication programming interface 122 and the application programming communication channel AP. The control result is output to thehandheld device 200, as shown in step S200.

部件控制作业包含多种形式，其中一种如表一第五列字段所示，类别字段指定对应的部件X，部件X可为车用音响设备，作业字段则为控制请求所要执行的作业，例如音响音量设定。接口形式关联于功能，例如当前音响音量显示，用于确认输入值形式是否符合需求。输入值关联于所要执行的作业，例如执行音响音量设定时，输入值为增加音量(+)及降低音量(-)。控制请求同样可以通过脚本，例如JSON语言依序写入文字指令及输入值成为指令封包。当然指令封包也会包含装置标识符或联机授权码等用于建立P2P通信所需要的信息。做为车用音响设备的部件X会有其他功能设定，而相关的控制请求仍可由对应的控制请求模块260产生，例如要选择均衡器模式时，就可以发出表一的第六列字段的控制请求，以输入值+/-在不同的内建均衡器模式中切换。There are many forms of component control operations, one of which is shown in the fifth column of Table 1. The category field specifies the corresponding component X, which can be a car audio device, and the job field is the job to be executed by the control request, for example Audio volume setting. The interface form is related to the function, such as the current audio volume display, which is used to confirm whether the input value form meets the requirements. The input value is associated with the operation to be performed, for example, when performing audio volume setting, the input value is to increase the volume (+) and decrease the volume (-). Control requests can also be written into text commands and input values sequentially through scripts, such as JSON language, into command packets. Of course, the command packet will also contain information required for establishing P2P communication, such as a device identifier or a connection authorization code. As the component X of the car audio equipment, there will be other function settings, and the related control request can still be generated by the correspondingcontrol request module 260. Control request to switch between different built-in equalizer modes with input value +/-.

部件控制作业可以是单纯的部件运作状态取得，以提供给手持装置200。例如，手持装置200用户需要目前车速时，车辆部件控制单元110就会驱动相关的车速检测机制，检测车速做为部件运作状态，并将部件运作状态输出作为控制结果。例如以部件Y做为车速检测模块，可由控制请求模块270发出如表一第七列字段的指令封包，以输入值TRUE触发部件Y响应，而将车辆时速回传以输出至手持装置200。The component control operation may be simply the acquisition of component operation status, which is provided to thehandheld device 200 . For example, when the user of thehandheld device 200 needs the current vehicle speed, the vehiclecomponent control unit 110 will drive the relevant vehicle speed detection mechanism, detect the vehicle speed as the component operation state, and output the component operation state as the control result. For example, if component Y is used as the vehicle speed detection module, thecontrol request module 270 can send a command packet as shown in the seventh column of Table 1, and the input value TRUE triggers component Y to respond, and the vehicle speed is returned for output to thehandheld device 200 .

另一种控制结果则是部件X、Y或车辆部件控制单元110拒绝接受控制请求，拒绝的原因包含相关功能锁定、车辆平台上欠缺对应部件X、Y、车款与当前车辆不符等，此时控制结果就会是控制失败的信息，而响应至手持装置200。Another control result is that component X, Y or the vehiclecomponent control unit 110 refuses to accept the control request. The reasons for the refusal include related function locking, lack of corresponding components X, Y on the vehicle platform, vehicle model does not match the current vehicle, etc. At this time, The control result will be a control failure message and a response to thehandheld device 200 .

如图5所示，应用程序通信接口122具体的接收指令封包的方式，包含主动询问。应用程序通信接口122依据一定周期发出询问信号进行扫描，而持续与手持装置200交握以维持配对连接状态；若没有指令封包需要发出，手持装置200仅单纯响应标识符、授权码及交握口令；若有指令封包需要发出，则手持装置200响应标识符、授权码及指令封包。As shown in FIG. 5 , the specific manner in which the applicationprogram communication interface 122 receives the instruction packet includes an active inquiry. Theapplication communication interface 122 sends an inquiry signal to scan according to a certain period, and keeps handshake with thehandheld device 200 to maintain the pairing connection state; if no command packet needs to be sent, thehandheld device 200 simply responds with the identifier, the authorization code and the handshake password ; If there is a command packet to be sent, thehandheld device 200 responds with the identifier, the authorization code and the command packet.

在有多个手持装置200与应用程序通信接口122完成配对的情况下，例如车辆平台中有多个成员，并且每个人的手持装置200、300v400、500、600都曾经与应用程序通信接口122完成配对。此时，应用程序通信接口122经由多个配对程序建立多个应用程序通信频道AP，而与多个手持装置200、300、400、500、600配对连接。此时，应用程序通信接口122就会依据一定周期，依序对各应用程序通信频道AP发出询问信号以进行扫描，用以接收来自多个手持装置200、300、400、500、600的多个指令封包。应用程序通信接口122根据这些指令封包的接收次序，识别各指令封包是否符合服务请求及控制请求。原则上，这些指令封包是依据接收次序被辨识，而确认服务请求或控制请求的内容，并依序执行之。若为相同应用服务A、B、C、D或部件X、Y之控制，是以最新的请求覆写旧的请求。当然，不同的手持装置200、300、400、500、600也可以设定为不同的权限，使得每一个手持装置200、300、400、500、600能关联到的应用服务A、B、C、D及部件X、Y有所不同；例如手机免持听筒相关的服务应用程序，就仅限于驾驶的手持装置200可以使用；又如音响等部件X、Y的细节设定，为了行车安全，限制驾驶的手持装置200不能使用。In the case where there aremultiple handsets 200 paired with theAPI 122 , eg, there are multiple members of the vehicle platform, and each of thehandsets 200 , 300v 400 , 500 , 600 has been paired with theAPI 122 pair. At this time, theapplication communication interface 122 establishes a plurality of application communication channels AP through a plurality of pairing programs, and is paired and connected with the plurality ofhandheld devices 200 , 300 , 400 , 500 and 600 . At this time, theapplication communication interface 122 will sequentially send an inquiry signal to each application communication channel AP according to a certain period to scan, so as to receive a plurality of command packet. The applicationprogram communication interface 122 identifies whether each command packet complies with the service request and the control request according to the receiving order of the command packets. In principle, these command packets are identified according to the receiving order, and the content of the service request or control request is confirmed and executed in sequence. If the same application serves the control of A, B, C, D or components X, Y, the old request is overwritten with the newest request. Of course, differenthandheld devices 200, 300, 400, 500, 600 can also be set to different permissions, so that eachhandheld device 200, 300, 400, 500, 600 can be associated with application services A, B, C, D and components X, Y are different; for example, the service application related to the hands-free handset of the mobile phone can only be used by thehandheld device 200 for driving; for example, the detailed settings of components X and Y such as audio are restricted for driving safety. Thehandheld device 200 for driving cannot be used.

本发明通过应用程序编程接口服务器128以及控制请求转送模块124的链接，解决了手持装置200无法连结车辆平台部件X、Y的技术问题，使得手持装置200可以更广泛地与车辆平台进行沟通而增加其应用方式。The present invention solves the technical problem that thehandheld device 200 cannot be connected to the vehicle platform components X and Y through the link of the applicationprogramming interface server 128 and the control request transfer module 124, so that thehandheld device 200 can communicate with the vehicle platform more widely and increase its application.
