本发明实施例中，车载终端具体可以访问智能洗车云服务器提供的洗车服务套餐查询接口，以查询洗车服务套餐。该洗车服务套餐查询接口的参数如下：
请求参数：随机密码authCode、车牌号；
响应参数：状态码、套餐ID、套餐名称、服务所需时间、原始价格、实际价格。
通过该洗车服务套餐查询接口，车载终端可以向服务器发送authCode作为鉴权校验的凭证，同时，服务器可以通过车载终端发送的车牌号获取车辆对应的用户账号。智能洗车云服务器可以通过状态码指示是否接收到车载终端洗调用洗车服务套餐查询接口发送的洗车套餐查询请求，响应于洗车套餐查询请求，智能洗车云服务器可以反馈至少一个洗车服务套餐，具体的洗车服务套餐信息可以包括套餐ID、套餐名称、服务所需时间、原始价格、实际价格。
作为一种可选的实施方式，车载终端在检测到用户确定出的目标服务套餐并且检测出硬件设备均处于洗车准备状态时可以调用智能洗车云服务器的
洗车启动接口，从而可以触发洗车机启动洗车服务：该洗车启动接口的参数如下：
请求参数：随机密码authCode、车牌号、车辆型号、套餐ID；
响应参数：状态码、预计服务所需时间。
其中，车载终端发送的套餐ID为目标服务套餐的ID，由于不同洗车服务套餐所需的洗车时间不同，不同车辆型号的尺寸也会影响洗车机的移动距离，因此服务器可以根据车载终端发送的车辆型号以及目标服务套餐的套 餐ID动态计算出目标服务套餐对应的洗车服务的预计服务所需时间。进一步的地，智能洗车云服务器可以根据车载终端通过该洗车启动接口发送的请求参数生成洗车请求消息，并由智能洗车服务器调用洗车机服务器的操作请求访问接口发送洗车请求消息。
5.在洗车服务进行的过程中同步显示洗车进度信息。
本发明实施例中，车载终端可以在获取到智能洗车云服务器反馈的预计服务所需时间之后，以倒计时的形式显示洗车进度。
6.在接收到服务器102转发的服务结束消息时，输出用于提示用户驾驶车辆离场的离场提示消息。
7.接收并输出服务器102发送的至少一个洗车点；以及，检测用户从至少一个洗车点中确定出的目标洗车点，并根据目标洗车点的地理位置以及车辆的地理位置进行导航，以使车辆根据导航信息行驶至目标洗车点。
可见，在本发明实施例中，通过调用智能洗车云服务器以及洗车机服务器提供的不同接口，洗车系统可以完成用户账号的鉴权验证、洗车套餐查询、车辆停车到位检测、洗车进度同步、洗车结果上报、车辆离场上报、支付结果推送、洗车启动等操作。在整个洗车过程中，用户只需选择洗车套餐并确定，从而可以解放用户的注意力，降低用户的操作复杂度和操作风险。
实施例三
请参阅图4，图4是本发明实施例公开的一种洗车方法的流程示意图。如图4所示，该洗车方法可以包括以下步骤：
401、洗车机在检测到车辆进入洗车机预设的车牌识别区域时，拍摄车辆的车牌照片，并将车牌照片发送至服务器。
在本发明实施例中，在车辆进入洗车机之前，可以通过以下方式查询洗车机的地理位置：
服务器在接收到车载终端发送的洗车点搜寻消息时，查询与车辆的地理位置之间的距离小于预设距离阈值的周边洗车点；以及，将周边洗车点发送至车载终端；此外，服务器还可以调用推荐系统查询洗车点，获取推荐系统返回的推荐的洗车点，并查询推荐的洗车点与周边洗车点中重复的洗车点，向车载终端发送上述重复的洗车点。
车载终端接收并输出服务器发送的至少一个洗车点；以及，检测用户从至少一个洗车点中确定出的目标洗车点，并根据目标洗车点的地理位置以及车辆的地理位置进行导航，以使车辆根据导航信息行驶至目标洗车点。
402、服务器通过识别车牌照片中的车牌获取与车辆对应的用户账号，向与用户账号对应的车载终端发送服务授权消息。
403、车载终端根据服务授权消息输出显示洗车页面，以供用户在洗车页面中进行洗车服务授权。
404、洗车机检测车辆是否已停入洗车机预设的洗车区域；如果是，向服务器发送车辆停入成功消息；如果否，向服务器发送车辆未停入消息。
405、服务器在检测到洗车服务已授权并且接收到洗车机发送的停入成功消息时，向车载终端发送洗车准备消 息；在接收到车辆未停入消息时，向车载终端转发车辆未停入消息。
406、车载终端在接收到洗车准备消息时，检测车辆的硬件是否均处于洗车准备状态；如果是，向服务器发送安全检测成功消息；如果否，输出状态提示消息。
作为一种可选的实施方式，车载终端在接收到洗车准备消息时，还可以输出用于提示用户控制车辆进入停车状态的停车提示消息。
407、车载终端在接收到车辆未停入消息时，输出用于引导用户控制车辆行驶至洗车区域的驾驶辅助消息。
408、服务器在接收到安全检测成功消息时，向洗车机发送洗车请求消息。此外，作为一种可选的实施方式，在车载终端接收到洗车准备消息之后，还可以执行以下步骤：
车载终端向服务器发送洗车套餐查询请求；
服务器在接收到车载终端发送的洗车套餐查询请求时，查询与洗车机对应的至少一个洗车服务套餐，并将至少一个洗车服务套餐发送至车载终端；
车载终端输出显示服务器发送的至少一个洗车服务套餐，并检测用户从至少一个洗车服务套餐中确定出的目标服务套餐，并将目标服务套餐发送至服务器；
服务器创建与目标服务套餐对应的洗车服务的洗车订单，以及，根据洗车订单对用户账号绑定的扣费账户进行扣费；
相应地，上述的步骤408的具体实施方式可以为：
服务器在接收到安全检测成功消息并且对扣费账户进行扣费成功时，向洗车机发送洗车请求消息。
409、洗车机在接收到洗车请求消息时，启动对车辆的洗车服务。
410、洗车机在洗车服务进行的过程中，将洗车服务的洗车进度信息实时上报至服务器，由服务器将洗车进度信息同步至车载终端中进行显示。
411、洗车机在洗车服务结束时，向服务器发送服务结束消息，由服务器将服务结束消息转发至车载终端，以使车载终端输出用于提示用户驾驶车辆离场的离场提示消息。
412、洗车机检测车辆是否驶离洗车区域；如果是，向服务器发送车辆离场消息；如果否，继续执行步骤412。
413、服务器在接收到车辆离场消息时，更新洗车服务对应的洗车订单的订单状态。
在图4所描述的方法中，通过洗车机、服务器以及车载终端三者之间的通信交互，可以在车辆驶入洗车机到车辆驶离洗车机的整个洗车过程中通过各种硬件状态的自动检测以及良好的交互流程，为用户提供便捷、安全及高效的洗车服务。
此外，本发明实施例公开一种计算机可读存储介质，其存储计算机程序，其中，该计算机程序使得计算机执行图4所示的洗车方法。
