具体实施方式
为使本申请实施的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行更加详细的描述。在附图中，自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。所描述的实施例是本申请一部分实施例，而不是全部的实施例。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。下面结合附图对本申请的实施例进行详细说明。
图1是本申请一实施例的汽车尾门控制方法的流程示意图。
如图1所示的汽车尾门控制方法包括：
步骤1：车身控制单元获取唤醒信号；
步骤2：车身控制单元根据唤醒信号生成AR传感器第一工作信号并通过LIN线传递给AR脚踢传感器；
步骤3：AR脚踢传感器根据AR传感器第一工作信号生成第一投影图像 并在使用者与第一投影图像互动后生成第一反馈信号；
步骤4：AR脚踢传感器将第一反馈信号传递给车身控制单元；
步骤5：车身控制单元根据第一反馈信号生成尾门打开控制信号并传递给尾门控制单元；
步骤6：尾门控制单元用于根据尾门打开控制信号进行尾门控制。
本申请的汽车尾门控制方法中，AR脚踢传感器是车身控制单元(汽车BCM)上的单独一路LIN节点，在需要进行投影工作时，车身控制单元仅唤醒AR脚踢传感器的单独一路LIN，通过LIN线给AR脚踢传感器发送AR传感器第一工作信号以使投影开启，而不唤醒整车。只有当用户携带合法钥匙踩踏投影时，车身控制单元才会唤醒整车，给尾门控制单元发送尾门开启指令。通过此控制***，可以解决当用户携带钥匙靠近车辆，而频繁唤醒整车的问题，有效的延长汽车的使用寿命。
在本实施例中，获取钥匙信号包括：车身控制单元获取通过硬线连接的蓝牙接收模块所传递的唤醒信号。
在本实施例中，蓝牙接收模块所传递的唤醒信号通过硬线传递给车身控制单元，而其他信号通过CAN线通过网关传递，采用这种方式，在仅需要唤醒AR脚踢传感器时，不需要由于蓝牙接收模块所传递的信号使得整车被唤醒，仅仅是蓝牙接收模块通过硬线将唤醒信号传递给车身控制单元即可。
在本实施例中，AR传感器工作信号包括尾门开启信号以及尾门关闭信号；
车身控制单元根据唤醒信号生成AR传感器工作信号并通过LIN线传递给所述AR脚踢传感器包括：
获取当前车辆状态；
根据当前车辆状态生成AR传感器工作信号。
在本实施例中，当前车辆状态包括非睡眠状态以及睡眠状态；
根据所述当前车辆状态生成AR传感器工作信号包括：
当当前车辆状态为非睡眠且解锁状态，则获取当前车辆档位信息；
根据当前车辆档位信息判断是否生成AR传感器工作信号。
在本实施例中，根据当前车辆档位信息判断是否生成AR传感器工作信号具体为：当车速为0且档位为P时，生成AR传感器工作信号。
采用这种方式，当非睡眠且解锁时，满足车速为0，档位为P投影时， 能够解决如下问题：
解锁之后，钥匙一般在车周围，这个时候再周期性找钥匙，对钥匙损耗较大。且解锁之后，一般会有上下电、启动等动作，还周期性找钥匙的话也会有冲突。
在本实施例中，根据当前车辆状态判断是否生成AR传感器工作信号进一步包括：
当所述当前车辆状态为睡眠状态或者闭锁状态，则判断蓝牙钥匙是否在解锁区域，若是，则
生成AR传感器工作信号。
在本实施例中，本申请的获取钥匙信号还可以包括：获取智能钥匙所传递的唤醒信号。
具体而言，如果整车处于睡眠状态，蓝牙天线和室外天线周期性检测行李箱附近是否有钥匙，钥匙包括蓝牙钥匙和智能钥匙。检测到蓝牙钥匙后，蓝牙接收模块通过硬线唤醒车身控制单元，车身控制单元唤醒AR传感器的一路LIN；检测到智能钥匙后，车身控制单元也是只唤醒AR传感器的一路LIN，给AR传感器发送投影开启命令，投影图案S1为开启尾门的状态投影。
可以理解的是，若整车处于非睡眠且闭锁状态，也重复上述步骤，检测到钥匙后，车身控制单元给AR传感器发送投影开启命令。
可以理解的是，若整车处于解锁状态，则判断车辆如果处于静止状态，且档位为P档，此时车身控制单元给AR传感器发送投影开启命令。
在本实施例中，汽车尾门控制方法进一步包括：
当尾门控制单元根据尾门控制信号进行尾门控制后，尾门控制单元向所述车身控制单元发送尾门开启状态信号；
车身控制单元根据尾门开启状态信号生成AR传感器第二工作信号并传递给所述AR脚踢传感器；
AR脚踢传感器根据AR传感器第二工作信号生成第二投影图像并在使用者与所述第二投影图像互动后生成第二反馈信号；
AR脚踢传感器将第二反馈信号传递给车身控制单元；
车身控制单元根据第二反馈信号生成尾门关闭控制信号并传递给尾门控制单元；
尾门控制单元用于根据尾门关闭控制信号进行尾门控制。
在本实施例中，当AR脚踢传感器生成第一投影图像(即向地面投射第一投影图像后)，蓝牙接收模块主动寻找蓝牙钥匙。当AR脚踢传感器检测到用户踩踏第一投影图像，则通过LIN线输入第一反馈信号给车身控制单元，同时检测到智能钥匙或蓝牙钥匙在附近，则车身控制单元给尾门控制单元发送尾门打开控制信号，同时给AR脚踢传感器发送AR传感器第二工作信号，使AR脚踢传感器根据所述AR传感器第二工作信号生成第二投影图像。
当AR脚踢传感器检测到用户踩踏第二投影图像时，也通过LIN线输入第二反馈信号给车身控制单元，车身控制单元检测到周围有智能钥匙或收到蓝牙钥匙的定位信号，则给尾门控制单元发送尾门关闭控制信号。
在本实施例中，本申请的汽车尾门控制方法进一步包括：
在所述AR脚踢传感器根据所述AR传感器第一工作信号生成第一投影图像后，获取车辆情况；
获取投影关闭数据库，所述投影关闭数据库包括多个投影关闭条件；
根据车辆情况以及投影关闭数据库判断是否需要关闭第一投影图像，若是，则
车身控制单元生成投影关闭信号并传递给AR脚踢传感器。
具体而言，投影关闭条件至少包括如下条件中的一个：
若车辆由解锁状态变为闭锁状态，则车身控制单元给AR传感器发送关闭投影命令，投影关闭。
若车辆处于解锁状态，且满足整车睡眠、车速非0以及档位非P中的至少一个条件时，车身控制单元给AR传感器发送关闭投影命令，投影关闭。
本申请所提出的汽车尾门控制方法，为了避免检测到蓝牙钥匙后频繁唤醒整车，AR脚踢传感器作为车身控制单元的LIN节点，单独接在一路LIN上；蓝牙接收模块与车身控制模块之间连接一根硬线，用来本地唤醒车身控制模块，当满足尾门开启条件时，才唤醒整车，以解决频繁唤醒整车的问题。
本申请所提出的汽车尾门控制方法，在车辆处于解锁且整车未休眠的状态下，不再周期性找钥匙，控制AR投影传感器一直处于投影状态，直至满足投影关闭条件，可以解决钥匙电池损耗严重的问题。解锁状态下就投影还能提升用户体验感。
本申请所提出的汽车尾门控制方法，投影图案考虑了尾门开启和尾门关闭两种图案形式，便于用户区分踩踏投影后可实现的功能。
参见图3，本申请还提供了一种汽车尾门控制***，汽车尾门控制*** 包括车身控制单元101、AR脚踢传感器102以及尾门控制单元103，车身控制单元101通过LIN线与所述AR脚踢传感器102连接，车身控制单元101与尾门控制单元103通过CAN线连接；其中，
车身控制单元用于获取唤醒信号；
车身控制单元用于根据唤醒信号生成AR传感器第一工作信号并通过LIN线传递给所述AR脚踢传感器；
AR脚踢传感器用于根据AR传感器第一工作信号生成第一投影图像并在使用者与第一投影图像互动后生成第一反馈信号；
AR脚踢传感器用于将第一反馈信号传递给所述车身控制单元；
车身控制单元用于根据第一反馈信号生成尾门打开控制信号并传递给尾门控制单元；
尾门控制单元用于根据尾门打开控制信号进行尾门控制。
在本实施例中，所述汽车尾门控制***进一步包括蓝牙接收模块，所述车身控制单元分别通过硬线方式以及CAN线方式与蓝牙接收模块直接连接，其中，唤醒信号通过硬线方式传递给车身控制单元。
相对于现有技术中通过CAN总线发送唤醒信号的方式，通过硬线发送信号不需要唤醒整车，从而节省了资源。
本申请还提供了一种通过车身控制单元控制汽车尾门的方法，

根据所述唤醒信号生成AR传感器第一工作信号并通过LIN线传递给所述AR脚踢传感器；
获取AR脚踢传感器反馈的第一反馈信号；
根据所述第一反馈信号生成尾门打开控制信号并传递给尾门控制单元。
本申请的通过车身控制单元控制汽车尾门的方法中，AR脚踢传感器是车身控制单元上的单独一路LIN节点，在需要进行投影工作时，车身控制单元仅唤醒AR脚踢传感器的单独一路LIN，通过LIN线给AR脚踢传感器发送AR传感器第一工作信号以使投影开启，而不唤醒整车。只有当用户携带 合法钥匙踩踏投影时，车身控制单元才会唤醒整车，给尾门控制单元发送尾门开启指令。通过此控制***，可以解决当用户携带钥匙靠近车辆，而频繁唤醒整车的问题，有效的延长汽车的使用寿命。
本申请还提供了一种车辆，所述车辆包括如上所述的汽车尾门控制***。
