现有的车辆故障诊断需要的诊断软件要么是诊断设备制造商在诊断设备出厂前配置完成，要么是用户拿到设备后获取使用，但是现阶段诊断设备配置的诊断软件包通常比较庞大，包含了各个主流车型的诊断软件。但是实际诊断过程中只需要某个或者其中几个诊断软件中的诊断功能模块就能实现车辆的诊断。由此导致了用户配置车辆诊断软件不够灵活，并造成资源浪费。基于上述技术问题，本实施例提供一种车辆诊断方法，能够根据用户的实际需求灵活配置诊断设备完成车辆的诊断，减少了资源的浪费。请参考图1，图1为本申请实施例提供的一种车辆诊断方法的***结构示意图。
本申请的车辆诊断***包括：服务器101、诊断设备102、车辆103。
服务器101可包括处理器、存储器等，其可以通过通讯接口与诊断设备102利用通讯网络进行通信连接，实现数据交互。
诊断设备102可以通过自身安装的客户端在用户交互界面上为用户提供获取指令的输入接口和获取指令的触发单元。在用户交互界面还可以包括多种显示和提醒信息。需要说明的是，本申请的上述通讯网络可以根据实际应用过程中的网络状况和应用需求来确定，既可以是无线通讯网络，如移动通讯网络或WIFI网络等，也可以是有线通讯网络，既可以是广域网，在情况允许时也可以采用局域网，此处不做具体限制。
车辆103为需要进行诊断的车辆即待诊断车辆，可以是家用轿车，也可以是商用车。车辆103上具有各种电子控制单元ECU，一方面ECU监控车辆运行的各种数据，另一方面ECU与外界交互车辆数据，从而保证车辆的正常运行。
具体的，服务器101、诊断设备102、车辆103之间的交互过程包括：诊断设备102建立与待诊断车辆103的连接并获取车辆信息，根据用户指令生成诊断软件的获取请求，获取请求包括用户信息和车辆信息，发送诊断软件的获取请求至服务器101，服务器101在接收到获取请求之后，根据车辆信息确定对应的诊断软件功能模块列表，将诊断软件功能模块列表发送至诊断设备102，诊断设备102将诊断软件功能模块列表呈现给用户，以使用户确定目标诊断功能模块，诊断设备102根据用户的指令发送目标诊断功能模块信息至服务器101，服务器101接收目标诊断功能模块信息，并根据用户信息判断用户是否具有目标诊断功能模块的授权资格，得到判断结果，根据判断结果执行对应的目标诊断功能模块获取操作，并发送给诊断设备102，诊断设备102接收服务器101反馈的操作结果，并根据获取到的目标诊断功能模块对待诊断车辆103进行诊断。
请参考图2，图2为本申请实施例提供的一种车辆诊断方法的流程图，该方法主要应用于服务器，该方法具体包括：
S201、获取诊断设备基于待诊断车辆发送的诊断软件的获取请求，获取请求包括用户信息和待诊断车辆的车辆信息。
获取请求用于诊断设备向服务器请求诊断软件，获取请求包括用户信息和待诊断车辆的车辆信息，该用户信息包括但是不限定于用户账号、用户手机号、用户姓名等信息。车辆信息包括但是不限定于车辆VIN码、车牌、唯一标记车辆的二维码。诊断设备在获取用户信息和车辆信息后，根据用户信息和车辆信息生成诊断软件的获取请求，并发送给服务器。
S202、根据车辆信息确定对应的诊断软件功能模块列表。
具体的，确定诊断软件功能模块列表的方式为：根据车辆信息确定待诊断车辆的车型信息，根据车型信息确定对应的目标诊断软件，根据目标诊断软件确定对应的诊断软件功能模块列表。在一个具体的实施例中，根 据车辆信息确定待诊断车辆的车型信息，进而通过车型信息确定对应的目标诊断软件，再根据目标诊断软件得到对应的诊断软件功能模块列表。例如，以车辆信息为VIN码来说明，待诊断车辆的VIN码是LSGKE5411LW058831，则通过该VIN码可以确定车型是别克英朗2019款，进一步确定对应的目标诊断软件为别克英朗2019款诊断软件，其中，别克英朗2019款诊断软件对应的诊断软件功能模块包括诊断快速检测、***扫描、***选择、ADAS校准，因此可以基于这些诊断功能模块生成别克英朗2019款诊断软件诊断功能模块列表。
S203、将诊断软件功能模块列表发送至诊断设备，以使诊断设备将诊断软件功能模块列表呈现给用户，以使用户确定目标诊断功能模块。
服务器将诊断软件功能模块列表发送至诊断设备，用户通过显示屏幕上的诊断软件功能模块列表进行选择，确定目标诊断功能模块。
在一个具体的实施例中，目标诊断功能模块列表可以是分级列表，例如，目标诊断功能模块列表为多级列表，其中一级列表包括但是不限定于：快速检测、***扫描、***选择、ADAS校准。当用户确定一级列表“***选择”后，得到“***选择”对应的二级列表，该二级列表包括但是不限定于ECM、ABS、BCM、BMS、SAS、TCM、SRS、IMM、TPMS，当用户选择二级列表ECM后，得到ECM对应的三级列表，该三级列表包括但是不限定于读故障码、清除故障记忆、读取数据流、动作测试、特殊功能、编程。
当用户确定一级列表ADAS校准后，得到二级列表，该二级列表包括但是不限定于前置相机模块、ACC模块以及全景模块。可以理解的是，用户可以对各级列表中的模块进行多项选择。不同的目标诊断软件对应的诊断软件功能模块列表可以相同，也可以不同。
本实施例不再对本步骤进行限定，用户可自定义设置，只要是能够实现本实施例的目的即可。
S204、接收由诊断设备发送的经用户确认的目标诊断功能模块信息。
当用户确认目标诊断功能模块后，诊断设备会发送确认的目标诊断功能模块信息至服务器。
S205、根据用户信息判断用户是否具有目标诊断功能模块的授权资格， 得到判断结果。
服务器根据用户信息判断该用户是否具有目标诊断功能模块的授权资格，得到判断结果。若判断结果为用户具有授权资格，则发送目标诊断功能模块至诊断设备，以使诊断设备配置目标诊断功能模块；若判断结果为用户不具有授权资格，则发送授权提示信息至诊断设备，以使用户确认是否需要取得授权，并在用户获得授权后发送目标诊断功能模块至诊断设备。此时用户可以基于诊断设备中的诊断软件进行车辆诊断。
具体的，根据上述用户信息确定对应的诊断软件授权信息，判断上述目标诊断功能模块与诊断软件授权信息是否匹配，若匹配，则判断上述用户是否具有目标诊断功能模块的授权资格，得到判断结果。
在一个具体的实施例中，服务器预存有基于用户信息的诊断软件授权信息数据库。该诊断软件授权信息数据库包括了大量的用户信息和诊断软件授权信息，并预先建立了用户信息和诊断软件授权信息的映射关系。用户信息对应一个诊断软件授权信息，也可以对应多个诊断软件授权信息。服务器在接收到目标诊断功能模块的获取请求后，根据该获取请求中的用户信息可以去查询信息数据库中是否存在该用户信息，如果存在则进一步根据映射关系确定对应的诊断软件授权信息。以用户信息为用户账号来进一步说明，当服务器接收诊断软件的获取请求后，获取用户的用户账号，分析确定用户账号为A时，则首先到信息数据库中查询是否存在该用户账号A，若存在，则进一步根据映射关系来确定对应的诊断软件授权信息。若不存在该用户账号A，则认为用户不具有诊断软件的授权资格。
在一个具体的实施例中，获取请求还包括请求使用期限，诊断软件授权信息包括授权诊断软件信息、授权诊断功能模块集合、授权期限，判断目标诊断功能模块与诊断软件授权信息是否匹配，具体包括：判断目标诊断软件与授权诊断软件信息是否匹配，若匹配则进一步判断目标诊断功能模块是否包含在授权诊断功能模块集合中，若授权诊断功能模块集合包含目标诊断功能模块，则判断请求使用期限是否在授权期限内，若是，则确定用户具有目标诊断功能模块的授权资格。具体的，首先判断目标诊断软件信息和授权诊断软件信息是否匹配，若是，则进一步判断目标诊断功能模块是否包含在授权诊断功能模块集合，若是，再进一步判断请求使用期 限是否包含在授权期限内，若是，则确定用户具有目标诊断功能模块的授权资格。以包含用户账号A及车辆VIN码的诊断软件获取请求为例，该获取请求包括车辆VIN码LSGKE5411LW05883，***选择功能模块，以及请求使用期限2020年5月25日14:00-18:00。首先通过该车辆VIN码确定目标诊断软件为别克英朗2019款诊断软件，通过服务器查询确定该用户账号A对应的诊断软件授权信息如下：授权诊断软件信息为别克英朗2019款诊断软件，授权诊断功能模块集合为快速检测、***扫描、***选择、ADAS校准，授权期限2020年5月24日19:00-2020年5月25日19:00，然后进一步分析，发现目标诊断软件和授权诊断软件均为别克英朗2019款诊断软件，从而判断目标诊断软件和授权诊断软件匹配，再进一步分析，授权诊断功能模块集合包含了***选择功能模块，请求使用期限包括在了授权期限期间。因此，可以判断该用户具有目标诊断功能模块的授权资格。假如服务器通过该用户账号A查询到的诊断软件授权信息中的授权诊断软件为别克君威2019款诊断软件，授权诊断功能模块集合为快速检测、***扫描、***选择、ADAS校准，授权期限2020年5月25日8:00-2020年5月26日8:00，则分析判断目标诊断软件和授权诊断软件信息不匹配，因此判断该用户不具有目标诊断功能模块的授权资格。又或者，服务器通过该用户账号A查询到的诊断软件授权信息中的授权诊断软件为别克英朗2019款诊断软件，授权诊断功能模块集合为快速检测、***扫描、ADAS校准，授权期限2020年5月25日8:00-2020年5月26日8:00，分析判断目标诊断软件和授权诊断软件信息匹配，但是目标诊断功能模块不在授权诊断功能模块集合里，因此判断该用户不具有目标诊断软件功能模块的授权资格。又或者，服务器通过该用户账号A查询到的诊断软件授权信息中的授权诊断软件信息为别克英朗2019款诊断软件，授权诊断功能模块集合为快速检测、***扫描、***选择、ADAS校准，授权期限2020年5月23日10:00-2020年5月24日10:00，分析判断目标诊断软件和授权诊断软件信息匹配，目标诊断功能模块在授权诊断功能模块集合里，但是，请求使用期限不包括在授权期限期间，因此判断该用户不具有目标诊断功能模块的授权资格。
进一步的，在用户具有目标诊断功能模块的授权资格后，诊断设备可 以获取目标诊断功能模块并进行使用。如果在使用过程中使用时长超过了授权期限，则服务器发送提示信息给诊断设备，以提醒用户重新获得授权。基于上述实施例，以用户账号A及车辆VIN码LSGKE5411LW05883为例，当确定该用户账号A对应的车辆具有***选择功能模块的授权资格后，用户就可以通过诊断设备获取***选择功能模块进行使用。当用户使用该目标诊断软件的使用期限从2020年5月25日14:00一直使用到了5月25日当天20:00，那么在用户使用到当天19:01时，已经超过了授权期限2020年5月24日19:00-2020年5月25日19:00,则服务器判断目标诊断功能模块的使用期限已经超过了授权期限，然后发送提示信息给诊断设备，以提醒用户重新获得授权。用户重新获得授权的方式包括但不限于购买、分时租赁，转让等。如果用户重新获得授权，则允许诊断设备继续使用该***选择功能模块，若用户没有继续获得授权，则终止诊断设备使用***选择功能模块。
S206、根据判断结果执行对应的目标诊断功能模块获取操作，并反馈给诊断设备，以使诊断设备根据获取到的目标诊断功能模块对待诊断车辆进行诊断。
具体的，若判断结果为用户具有授权资格，则发送目标诊断功能模块至诊断设备，以使诊断设备配置目标诊断功能模块；
若判断结果为用户不具有授权资格，则发送授权提示信息至诊断设备，以使用户确认是否需要取得授权，并在用户获得授权后发送述目标诊断功能模块至诊断设备。
基于上述实施例，当获取请求包括用户账号A及车辆VIN码LSGKE5411LW05883，服务器判断具有目标诊断功能模块为别克英朗2019款***选择功能模块的授权资格时，则将***选择功能模块的软件包发送至诊断设备，以使诊断设备配置并安装该目标诊断功能模块。若服务器判断该车辆不具有别克英朗2019款***选择功能模块的授权资格时，则发送提示信息如“您不具有别克英朗2019款***选择功能模块的授权资格，请获取授权”至诊断设备，以提醒用户获得授权。在用户确认需要获得授权时，提供获得授权的方式方便用户办理授权。获取该授权资格的方式包括但不限于购买、分时租赁，租借、从他人转让等。在用户选择其中的一种 获取方式并完成授权后，服务器根据授权结果生成一条新的目标诊断功能模块授权信息并存储在诊断软件授权信息数据库。同时，服务器根据用户获得的授权将对应的目标诊断功能模块发送至诊断设备以使诊断设备配置该目标诊断功能模块并使用。
基于上述技术方案，本实施例中服务器基于获取请求判断用户是否具有目标诊断功能模块的授权资格，得到判断结果，只有具有授权资格才能够进行目标诊断功能模块的下载，实现诊断设备的单个功能模块的灵活配置，能够根据用户的实际需求灵活配置诊断设备完成车辆的诊断，提升了诊断功能模块的使用率，实现了车辆的诊断。

S305、判断用户是否具有目标诊断功能模块的授权资格。
具体的，当目标诊断软件与授权诊断软件信息匹配，目标诊断功能模块包含在授权诊断功能模块集合，用户请求使用期限包括在授权期限，则认为用户具有目标诊断功能模块的授权资格。
若具有授权资格，则进入S306，若不匹配，则进入步骤S311。
S306、确定用户具有目标诊断功能模块的授权资格。
S307、获取目标诊断软件的最新版本信息。
具体的，服务器可以从诊断软件库里获取目标诊断软件的最新版本信 息。
S308、判断授权版本信息与目标诊断软件的最新版本信息是否匹配。
若匹配，则进入步骤S309，若不匹配，则进入步骤S310。
具体的，诊断软件授权信息还包括了授权版本信息。可以通过对比授权版本信息与获取到的目标诊断软件的最新版本信息是否一致来确定两者是否匹配。基于上述实施例，根据车辆VIN码LSGKE5411LW058831确定了目标诊断软件为别克英朗2019款诊断软件，根据用户账号A确定了授权诊断软件也为别克英朗2019款诊断软件且授权版本是V2.0。当在服务器中的诊断软件库获取到目标软件的最新版本信息为别克英朗2019款诊断软件V2.0，由于最新版本信息与授权版本信息一致，则判断授权版本信息与目标诊断软件的最新版本信息匹配。当在服务器中的诊断软件库获取到目标软件的最新版本信息为别克英朗2019款诊断软件V3.0，由于最新版本信息与授权版本信息不一致，则判断授权版本信息与目标诊断软件的最新版本信息不匹配。
S309、发送目标诊断软件至诊断设备，以使诊断设备配置该目标诊断软件。
当判断最新版本信息与授权版本信息匹配时，服务器发送目标诊断功能模块至诊断设备，以使诊断设备安装目标诊断功能模块并使用。可以理解的是，目标诊断软件包含各目标诊断功能模块。
S310、发送提示信息至诊断设备，以使用户确认是否需要对授权诊断软件进行升级。
当判断最新版本信息与授权版本信息不匹配时，如服务器的获取的目标诊断软件的最新版本信息为别克英朗2019款诊断软件V3.0，而授权诊断软件为别克英朗2019款诊断软件V2.0，则服务器发送提示信息如“您的授权诊断软件版本较低，是否升级为最新版本”至诊断设备，以使用户确认是否需要对授权诊断软件进行升级。
进一步的，当用户确认进行升级时，诊断设备根据用户的指令发送升级请求至服务器。服务器在收到升级请求时，判断诊断软件授权信息是否包含升级权限，若包含升级权限，则发送最新版本的目标诊断软件至诊断设备，以使该诊断设备配置目标诊断软件，并更新该授权诊断软件的授权 版本信息；若不包含升级权限，则发送升级提示信息至诊断设备，以提醒用户获取升级权限。
具体的，如果用户确认进行升级，服务器在接收到诊断发送的升级请求后，首先判断用户是否具有升级权限，若有，则发送最新版本的目标诊断功能模块如别克英朗2019款***选择功能模块V3.0至该诊断设备，以使该诊断设备安装并配置该功能模块，同时服务器将诊断软件授权信息更新为别克英朗2019款诊断软件V3.0。若判断用户没有升级权限，则发送升级提示信息如“您不具有升级权限，请先获取升级权限后再升级软件”至诊断设备，以提醒用户获取升级权限。在用户获取升级权限后，将最新版本的目标诊断软件的目标诊断功能模块发送至诊断设备并更新诊断软件授权信息中的授权版本信息。若用户不同意获取升级权限，则将授权诊断软件的目标诊断功能模块发送至诊断设备，同时不更新授权诊断软件的版本信息。
S311、发送授权提示信息至诊断设备，以使用户确认是否需要取得授权。
该步骤可以参考S206中不具有授权资格时的操作，此处不再赘述。
在该实施例中，服务器在基于用户信息和车辆信息判断用户具有目标诊断功能模块的授权资格后，还可以通过比较目标诊断软件的最新版本和授权版本是否一致，并在不一致时提醒用户升级来使用户获得最新版本的目标诊断软件，从而进一步提升了用户体验。
图4为本申请实施例提供的另一种车辆诊断方法的流程图，该方法应用于诊断设备，该诊断设备可以是手持设备，移动终端、个人数字助理等具有加载诊断软件并进行车辆诊断功能的终端，该方法具体包括：
S401、建立与待诊断车辆的连接并获取车辆信息。
S402、根据用户指令生成诊断软件的获取请求，获取请求包括车辆信息和用户信息。
其中，获取请求用于诊断设备向服务器请求诊断软件，获取请求包括用户信息和待诊断车辆的车辆信息，该用户信息包括但是不限定于用户账号、用户手机号、用户姓名等信息。待诊断车辆信息的获取是诊断设备建 立与待诊断车辆的连接后，得到的车辆信息。车辆信息包括但是不限定于车辆VIN码、车牌、唯一标记车辆的二维码。
S403、发送诊断软件的获取请求至服务器，以使服务器根据车辆信息确定对应的诊断软件功能模块列表。
S404、接收诊断软件功能模块列表并呈现给用户，以使用户确定目标诊断功能模块。
S405、发送目标诊断功能模块的信息至服务器，以使服务器根据用户信息判断用户是否具有目标诊断功能模块的授权资格，并根据判断结果执行对应的目标诊断功能模块的获取操作。
S406、接收服务器反馈的操作结果，并根据获取到的目标诊断功能模块对待诊断车辆进行诊断。
进一步的，在判断结果为具有授权资格之后，方法还包括：
接收服务器的授权诊断软件升级提示信息并呈现给用户，以使用户确认是否需要升级；
若用户确认需要升级，则发送升级请求至服务器，以使服务器判断是否具有升级权限，在服务器判断具有升级权限时接收由服务器发送的最新版本的目标诊断功能模块并配置；在服务器判断不具有升级权限时接收由服务器发送的升级权限提醒并呈现给用户，以提醒用户获取升级权限；
若用户确认不需要升级，则接收服务器发送的目标诊断功能模块并配置目标诊断功能模块。
在一个具体的实例中，诊断软件的获取请求包括用户信息、车辆信息。该获取请求被诊断设备发送服务器后，服务器基于用户信息获取授权诊断软件信息，基于车辆信息确定诊断软件功能模块列表，将诊断软件功能模块列表发送至诊断设备，以使用户确定目标诊断功能模块，然后判断目标诊断软件功能模块与授权诊断软件信息是否匹配，若匹配则确定用户具有目标诊断软件功能模块的授权资格。在另一个具体的实例中，诊断软件的获取请求包括用户信息、车辆信息、请求使用期限。该获取请求被诊断设备发送至服务器后，服务器基于用户信息获取授权诊断软件信息、授权期限，基于车辆信息确定诊断软件功能模块列表，将诊断软件功能模块列表发送至诊断设备，以使用户确定目标诊断功能模块，然后判断目标诊断软 件功能模块与授权诊断软件信息是否匹配，若匹配，进一步判断请求使用期限是否包含在授权期限内，若是，则确定用户具有目标诊断软件功能模块的授权资格。此时服务器向诊断设备发送目标诊断功能模块，若否，则确定用户不具有目标诊断软件功能模块的授权资格，此时服务器向诊断设备发送授权提示信息提示用户获取授权。服务器的目标诊断功能模块获取过程以及判断是否匹配的过程可以参照上文中有关服务器实施例的描述，此处不再赘述。
进一步的，当该判断结果为具有授权资格时，诊断设备接收服务器发送的目标诊断功能模块并配置该目标诊断功能模块后使用。当判断结果为不具有授权资格时，诊断设备接收服务器发送的授权提示信息并呈现给用户，以使用户确认是否需要获得授权。
以诊断设备获取的用户账号A和车辆VIN码LSGKE5411LW058831为例，当诊断设备基于用户账号和车辆VIN码生成诊断软件的获取请求并发送给服务器后，服务器根据车辆VIN码确定诊断软件功能模块列表并发送给诊断设备，诊断设备接收若服务器发送的诊断软件功能模块列表快速检测、***扫描、***选择、ADAS校准并呈现给用户，待用户确定***选择诊断功能模块后，诊断设备将***选择诊断功能模块信息发送至服务器。服务器判断具有授权资格，则诊断设备会接收到服务器发送的***选择诊断功能模块。若服务器不具有授权资格，此时诊断设备会收到服务器发送的“您不具有别克英朗2019款***选择诊断功能模块的授权资格，请获取授权”提示信息。当用户确认需要授权时，在诊断设备界面显示多种授权获取方式如购买、分时租赁、租借、从他人转让等。在用户选择其中的一种获取方式并完成授权后，服务器将该授权对应的目标诊断功能模块发送至诊断设备以使诊断设备配置该目标诊断功能模块并使用。
进一步的，诊断设备在获取目标诊断功能模块后，如果在使用过程中使用时长超过了授权期限，诊断设备将收到服务器发送的授权过期提醒，例如“您的诊断软件授权已过期，请重新获取授权”。该提醒可以是在使用时间刚超过授权期限终止时间提醒，也可以是在授权期限终止时间前预设时间阈值提醒，例如在授权期限终止时间前30min提醒等。本处不做具体限定。若用户通过诊断设备确认重新获取授权，则在用户完成重新授权后， 诊断设备继续使用该目标诊断功能模块；若用户没有继续获得授权，则终止诊断设备使用目标诊断功能模块。
进一步的，当判断结果为具有授权资格后，诊断设备接收服务器的授权诊断软件升级提示信息并呈现给用户，以使该用户确认是否需要升级，若用户确认需要升级，则发送升级请求至服务器，以使服务器判断是否具有升级权限，在服务器判断具有升级权限时接收由服务器发送的最新版本的目标诊断功能模块并配置，在服务器判断不具有升级权限时接收由服务器发送的升级权限提醒并呈现给用户，以提醒用户获取升级权限。若用户确认不需要升级，则接收服务器发送的目标诊断功能模块并配置目标诊断功能模块。
具体的，当判断结果为具有授权资格时，服务器进一步比较授权版本信息与获取到的目标软件的最新版本信息是否一致来确定两者是否匹配。当最新版本信息与授权版本信息匹配时，诊断设备会收到服务器发送的目标诊断功能模块并配置使用。当最新版本信息与授权版本信息不匹配时，诊断设备会收到服务器发送的升级提醒如“您的授权诊断软件版本较低，是否升级为最新版本”并呈现给用户。若用户确认需要升级，诊断设备根据用户的指令发送升级请求至服务器，以使服务器判断诊断软件授权信息中是否包含升级权限。在包含的情况下诊断设备将会收到服务器发送的最新版本的目标诊断功能模块并配置使用，若不包含，则诊断设备会收到服务器发送的升级权限获取提示信息如“您不具有升级权限，请先获取升级权限后再升级软件”并呈现给用户。在用户确认需要获取升级权限并完成升级权限的获取后，诊断设备将会收到服务器发送的最新版本的目标诊断功能模块并配置使用。如果用户确认不需要获取升级权限，则诊断设备获取授权诊断软件的诊断功能模块并配置使用。
在本实施例中，诊断设备通过用户信息和车辆信息对诊断软件进行配置和使用，灵活调整诊断设备的配置，诊断软件使用率更高，更好完成汽车诊断，用户体验更好。
