下面结合附图和具体实施例对本发明做进一步详细的说明。
如图1所示为本发明一种车辆发动机盖的解锁方法的工作流程图，包括：
步骤S101，包括：获取动作传感器发送的动作信号，执行步骤S102；
步骤S102，包括：如果接收到的动作信号匹配预设的解锁动作信号，则执行步骤S103，否则不执行步骤S103；
其中，所述预设的解锁动作信号是用户预先设置的动作信号，当动作传感器发送的动作信号与所述预设的解锁动作信号匹配，则可以认为用户执行了预先设置的动作。
步骤S103，包括：向机盖锁发送解锁信号，所述解锁信号控制机盖锁对车辆发动机盖执行解锁操作。
动作传感器用于检测用户对车辆的动作，步骤S101获取动作传感器发送的动作信号，步骤S102将动作信号与预设的解锁动作信号进行匹配检测。
在步骤S103中向机盖锁发送解锁信号，使得机盖锁执行解锁操作。
发动机盖也称为车前盖，机盖锁可以包括有控制解锁的执行机构，解锁信号可以是一个发送到执行机构的高电平或者低电平，执行机构接收到解锁信号后执行解锁操作。其中，当步骤S102接收到的动作信号与预设的解锁动作信号不匹配，则不执行步骤S103，可以继续执行步骤S101，持续获取动作信号，也可以结束步骤。优选地，当步骤S102接收到的动作信号与预设的解锁动作信号不匹配，则执行步骤S101。
由于采用了动作传感器检测用户对车辆的动作，因此相比现有技术中用户必须进 入乘客舱才能对发动机盖进行解锁的情况，本发明用户只需要在发动机盖前进行动作就能对发动机盖进行解锁，无需进入乘客舱解锁，操作既便利而又富有科技感。
在其中一个实施例中，所述动作传感器为检测用户手势的手势动作传感器，所述动作信号为手势动作信号。
手势动作传感器对用户手势进行检测，将用户手势转换为动作信号。当所产生的动作信号与预先设定的解锁动作信号匹配时，则会触发步骤S103对发动机盖进行解锁。用户可以预先通过手势动作传感器录制解锁手势，并由手势动作传感器将其转换为对应的解锁动作信号后保存。
解锁动作信号可以是对一次挥手或多次挥手的手势动作进行转换后的信号。当用户进行一次挥手或多次挥手时，对应的手势动作传感器捕捉到手势并转换为动作信号后，与解锁动作信号进行比较，当两者匹配时，触发步骤S103对发动机盖进行解锁。
在其中一个实施例中，所述手势动作传感器为摄像装置或红外检测装置。
摄像装置通过摄录用户的手势，并进行手势分析，确定手势特征，从而转换为相应的手势动作信号。例如采用手势标识作为手势动作信号，不同的手势采用唯一的数字进行标识。用户预先设定例如握拳、一个手指摆动、两个手指摆动等解锁手势，将解锁手势的手势标识保存作为解锁动作信号。当用户在摄像装置前作出手势时，摄像装置捕捉到视频，从视频中分离出手部图片，并对图片进行图像分析，则可以获取到用户手势，并获取对应的手势标识。将获取到的用户手势所对应的手势标识与作为解锁动作信号的手势标识进行比较，如果一致则触发步骤S103对发动机盖进行解锁。
红外检测装置通过红外光检测用户手势并转换为相应的手势动作信号。例如采用挥手次数大于预设次数阈值且挥手时间间隙小于预设时间间隙阈值作为手势动作信号。如用户可以将挥手两次以上且挥手时间间隙小于1秒作为解锁动作信号。当用户在红外检测装置前进行挥手，红外检测装置判断到红外光被遮挡，根据遮挡时间和次数等参数，判断出挥手次数及挥手时间间隙。将获取到的用户手势所对应的挥手次数及挥手时间间隙与作为解锁动作信号的挥手次数及挥手时间间隙进行比较，如果一致则触发步骤S103对发动机盖进行解锁。
在其中一个实施例中，所述摄像装置设置在所述车辆的车顶上方前端区域81、内后视镜区域82、前挡风玻璃边缘区域83、仪表盘84、外后视镜85或者A柱86上，且所述摄像装置的摄像方向为朝向所述车辆的车头方向。
如图8和图9所示，摄像装置可以安装在汽车的前风挡玻璃周边区域。优选为车顶上方前端区域81、内后视镜区域82、前挡风玻璃边缘区域83、仪表盘84、外后视 镜85或者左右A柱86上。其中，车顶上方前端区域81优选为从挡风玻璃的边缘向车顶方向扩展600毫米的车辆外部区域，内后视镜区域82优选为内后视镜及周边300毫米所围成的区域，前挡风玻璃边缘区域83优选为前挡风玻璃离玻璃边缘400毫米所围成的区域。A柱即左前方和右前方连接车顶和前舱的连接柱。摄像装置还可以是行车记录仪，由行车记录仪捕捉用户手势。
在其中一个实施例中，所述红外检测装置的有效检测区域为从所述车辆车头的车辆外轮廓向内扩展预设距离的区域。
红外检测装置可以设置在车辆前端，如图10所示，红外检测装置的有效检测区域为从所述车辆车头部分的车辆外轮廓1001向内(如图10的箭头方向)扩展预设距离的区域1002。优选地，红外检测装置的有效检测区域为从所述车辆车头部分的车辆外轮廓1001向内600毫米，且红外检测装置的有效检测区域延伸至延伸到前风挡玻璃1003上方。最优选位置为发动机盖的机盖锁上方。
本实施例通过对红外检测装置的有效检测区域进行限制，对红外检测装置的设置方式，可以提升客户便利性，在该区域客户感知体验好。红外检测装置可以根据有效检测区域及红外检测装置的感应距离进行设置，例如传感器感应距离为300毫米时，最远可以布置在离车外轮廓900毫米的位置。
在其中一个实施例中，所述动作传感器为检测用户对发动机盖动作的接触式动作传感器，所述动作信号为接触式动作信号。
接触式动作传感器用于检测用户对发动机盖的接触动作，当用户对发动机盖进行例如按压等动作时，接触式动作传感器将所检测到的动作转换为相应的动作信号，当所产生的动作信号与预先设定的解锁动作信号匹配时，则会触发步骤S103对发动机盖进行解锁。
在其中一个实施例中，所述接触式动作传感器为按压传感器或角度传感器。
当用户对发动机盖进行动作时，通过按压传感器和角度传感器检测到发动机盖所发生的按压或者角度变化，从而执行步骤S102进行判断，并在所产生的动作信号与预先设定的解锁动作信号匹配时，触发步骤S103对发动机盖进行解锁。
在其中一个实施例中，所述按压传感器设置在所述车辆的前保险杠、前大灯和前横梁所围成的范围内、设置在所述前保险杠上、设置在所述前大灯上、或设置在所述前横梁上。
其中，如图11所示，按压传感器可以设置在车头的前保险杠1101、前大灯1102和车身横梁1103上，或者前保险杠1101、前大灯1102和车身横梁1103所围成的区域 1104内。角度传感器可以设置在锁体的转动机构上。
如图12和图13所示，作为其中一个实施例，按压传感器1201设置在前保险杠1202用于承载发动机盖的承载面1203上。按压传感器1201可以是如图12所示的纵向布置，也可以是如图13所示的横向布置或其他任意方向。如图14所示，当发动机盖1204关闭时，其未对按压传感器1201施加压力，此时不触发步骤S103，机盖锁1205锁紧发动机盖。如图15所示，当用户按压发动机盖1204时，发动机盖1204受力向下对按压传感器1201施加压力，从而触发步骤S103对发动机盖进行解锁。
在其中一个实施例中，如图2和图3所示，所述机盖锁1包括锁体19、释放机构11和转动机构12，所述锁体19与所述车辆发动机盖连接，所述转动机构12能绕固定在所述锁体19上的转轴124旋转以与所述释放机构11配合形成锁止状态或解锁状态。所述转动机构12在锁止状态下向锁止发生方向旋转则触发所述接触式动作传感器14发送所述动作信号。其中在步骤S103中，当机盖锁1对车辆发动机盖执行解锁操作时，所述转动机构12向解锁发生方向旋转以使转动机构12从锁止状态切换为解锁状态；当机盖锁1对车辆发动机盖执行上锁操作时，所述转动机构12向锁止发生方向旋转以使转动机构12从解锁状态切换为锁止状态。
本实施例通过接触式动作传感器14检测车辆发动机盖在转动机构12处于锁止状态下是否仍然受到按压，具体来说，车辆发动机盖如果执行上锁操作，则转动机构向锁止发生方向旋转，车辆发动机盖如果执行解锁操作，则转动机构向解锁发生方向旋转。在本实施例中，锁止发生方向为逆时针方向，且相应的解锁发生方向为顺时针方向。此外，锁止发生方向还可以是顺时针，则相应的解锁发生方向为逆时针，结构也随之相应调整。当车辆发动机盖执行上锁操作时转动机构切换为锁止状态，此时如果转动机构继续向锁止发生方向旋转，则表明车辆发动机盖受到外力按压，因此，当检测到转动机构12在锁止状态下向锁止发生方向旋转时，则可以判断发动机盖受到外力按压，此时接触式动作传感器14发出动作信号触发步骤S101。其中转动机构处于锁止状态，即转动机构被释放机构锁定从而阻止转动机构向解锁发生方向旋转，转动机构处于解锁状态，即释放机构解除阻止转动机构向解锁发生方向旋转。
接触式动作传感器14对转动机构12的转动进行监测，在一个实施例中，接触式动作传感器14可以为设置在转动机构转轴旁的角度传感器，角度传感器对转动机构12的转动角度进行检测，当转动机构12在锁止状态下旋转超过预设触发角度时，则角度传感器发送动作信号。此外，还可以是如下的方式实现。
在其中一个实施例中，如图3所示为本发明最佳实施例的转动机构处于锁止状态 下的放大图，如图4所示为本发明最佳实施例的转动机构受到用户按压的放大图，所述转动机构12包括锁舌121，所述释放机构11包括与所述锁舌121配合的缺口111，所述锁舌在所述转动机构转动时与所述缺口配合形成锁止状态或解锁状态，所述锁舌下方设有第一凸块123，所述接触式动作传感器14为第一按压传感器，当所述转动机构12在锁止状态下向锁止发生方向旋转，使得所述第一凸块按压所述第一按压传感器时，触发所述第一按压传感器输出所述动作信号。
优选地，第一凸块123设置在锁舌121的下方，且所述第一按压传感器设置在所述第一凸块123下方。
如图3所示，当转动机构处于锁止状态下时，第一凸块123并不会按压接触式动作传感器14，如图4所示，当转动机构受到用户按压时，第一凸块123按压接触式动作传感器14，从而触发第一按压传感器输出所述动作信号。
相对于容易因为湿度等外部环境因素造成故障的电子检测方式，本实施例采用机械按压方式实现检测所述转动机构12在锁止状态下向锁止发生方向旋转更为可靠。其中，锁舌与缺口形成锁止状态即：锁舌被缺口卡紧，从而阻止转动机构向解锁发生方向旋转；锁舌与缺口形成解锁状态即：锁舌从缺口分离，从而使得转动机构可以向解锁发生方向旋转。
在其中一个实施例中，所述步骤S101，具体包括：
响应于接收到的整车解锁信号，读取档位信息和对车辆发动机盖的开关状态进行监测的锁状态传感器的输出信号，如果档位信息为挂泊车档位且所述锁状态传感器的输出信号为标识所述车辆发动机盖的开关状态为关闭状态的关闭信号，则获取接触式动作传感器发送的动作信号，执行步骤S102，如果档位信息为非挂泊车档位或所述锁状态传感器的输出信号是标识所述车辆发动机盖为开启状态的开启信号，则不执行步骤S102。
本实施例在整车解锁之前，任何对于发动机盖的按压，都不会有任何动作，整车解锁之后，车载电脑(Electronic Control Unit，ECU)会输出整车解锁信号，从而唤醒本***，读取档位信息(从而确定是否泊车)以及发动机盖的开关状态信息，当两者都符合条件时，再读取接触式动作传感器的动作信号，此时如果有用户去按压发动机盖，则会产生动作信号，从而被***读取并进行后续判断和操作。本实施例仅在整车解锁的状态下，才进行自动解锁，因此能够确保用户的财产安全。而先读取车辆是否处于泊车档位，则能确保用户行车安全，避免误触发操作。而且，***较为简单，更为节电。同时，由于客户正常情况下是在整车解锁之后才需要对发动机盖进行解锁， 因此本实施例的解锁方式也符合客户的正常使用情况。
优选地，当整车上锁时，车载电脑(Electronic Control Unit，ECU)会输出整车上锁信号，此时停止读取接触式动作传感器的动作信号，或者当档位信息发生变化使得档位信息不再是挂泊车档位，或者当锁状态传感器的输出信号是标识所述车辆发动机盖为开启状态的开启信号时，停止读取接触式动作传感器的动作信号。
在其中一个实施例中，如图2和图3所示，所述机盖锁1包括锁体19、释放机构11和转动机构12，所述锁体19与所述车辆发动机盖连接，所述转动机构12能绕固定在所述锁体19上的转轴124旋转以与所述释放机构11配合形成锁止状态或解锁状态，其中，当执行步骤S103时，机盖锁1对车辆发动机盖执行解锁操作使得所述转动机构12向解锁发生方向旋转从锁止状态切换为解锁状态，机盖锁1对车辆发动机盖执行上锁操作使得所述转动机构12向锁止发生方向旋转从解锁状态切换为锁止状态，当所述转动机构12为锁止状态时，触发所述锁状态传感器13输出标识车辆发动机盖为关闭状态的关闭信号，当所述转动机构12为解锁状态时，触发所述锁状态传感器13输出标识车辆发动机盖为开启状态的开启信号。
本实施例通过锁状态传感器13检测转动机构12是处于锁止状态还是处于解锁状态，转动机构12的锁止状态或解锁状态与车辆发动机盖的开关状态相对应，因此，通过检测转动机构12处于锁止状态或者解锁状态以判断车辆发动机盖的开关状态。其中，关闭信号与开启信号为锁状态传感器输出信号的具体信号。其中转动机构处于锁止状态即转动机构被释放机构锁定从而阻止转动机构向解锁发生方向旋转，转动机构处于解锁状态即释放机构解除阻止转动机构向解锁发生方向旋转。
锁状态传感器13对转动机构12的转动进行监测，在本申请的一个实施例中，锁状态传感器13可以为设置在转动机构转轴旁的锁状态角度传感器，锁状态角度传感器对转动机构12的转动角度进行检测，当转动机构12向锁止发生方向旋转超过预设的锁止角度时，则触发锁状态角度传感器输出标识车辆发动机盖的开关状态为关闭状态的关闭信号，当转动机构12向解锁发生方向旋转超过预设的解锁角度时，则触发锁状态角度传感器输出标识车辆发动机盖的开关状态为开启状态的开启信号。此外，还可以是如下的方式实现。
在其中一个实施例中，如图3所示为本发明最佳实施例的转动机构处于锁止状态下的放大图，如图5所示为本发明最佳实施例的转动机构处于解锁状态下的放大图，所述转动机构12包括锁舌121，所述释放机构11包括与所述锁舌121配合的缺口111，所述锁舌121在所述转动机构12转动时与所述缺口111配合形成锁止状态或解锁状态， 所述锁舌121设有第二凸块122，所述锁状态传感器13为第二按压传感器，在所述转动机构12处于锁止状态下所述第二凸块122持续按压所述第二按压传感器使得所述第二按压传感器输出标识车辆发动机盖的开关状态为关闭状态的关闭信号，在所述转动机构12处于解锁状态下所述第二凸块122与所述第二按压传感器分离使得所述第二按压传感器输出标识车辆发动机盖的开关状态为开启状态的开启信号。
优选地，第二凸块122设置在锁舌121的下方，且所述第二按压传感器设置在所述第二凸块122下方。
其中，锁舌与缺口形成锁止状态即锁舌被缺口卡紧从而阻止转动机构向解锁发生方向旋转，锁舌与缺口形成解锁状态即锁舌从缺口分离，从而使得转动机构可以向解锁发生方向旋转。
如图3所示，当转动机构12处于锁止状态下，第二凸块122持续按压所述第二按压传感器使得所述第二按压传感器输出标识车辆发动机盖的开关状态为关闭状态的关闭信号，而如图5所示，当转动机构12处于解锁状态下，第二凸块122与所述第二按压传感器分离使得所述第二按压传感器输出标识车辆发动机盖的开关状态为开启状态的开启信号。关闭信号可以是高电平，相应地开启信号为低电平，关闭信号也可以是低电平，相应地开启信号为高电平。
在其中一个实施例中，所述解锁动作信号为一个信号或连续多个信号的组合。
解锁动作信号可以是用户预先设置的一个信号，当接收到的动作信号与预设的解锁动作信号相同时执行步骤S103。例如，如果动作传感器是手势动作传感器，则当手势动作传感器所发出的动作信号所表示的手势(例如向左或者向右挥动)与预存的手势信号相同时，执行步骤S103。
解锁动作信号也可以是用户预先设置的连续多个信号的组合，当接收到的连续多个动作信号与预设的解锁动作信号相同时，执行步骤S103。例如，预设的解锁动作信号为在预设时间内连续读取到两个动作信号，即当接收到动作信号后，检测到与之前的动作信号之间的时间在预设时间内，则执行步骤S103。当接触式动作传感器是按压传感器时，动作信号为按压信号，则解锁动作信号可以进一步为在预设时间内连续读取到两个按压信号。
采用连续多个信号的组合，能够避免单一信号时容易误触发的情况，例如用户需要连续按压两次才会触发解锁，则能避免用户意外按压的情况。
作为本发明最佳实施例，机械结构由以下部分组成:机盖锁1、执行机构2、处理器3。
机盖锁1为处理器3提供锁定/解锁及相关信号的读取等功能，所述机盖锁1包括释放机构11、转动机构12、锁状态传感器13、接触式动作传感器14、释放机构弹簧15、转动机构弹簧16、释放机构铆钉17、转动机构铆钉18、锁体19。转动机构12用于对车辆发动机盖进行锁止或解锁，当转动机构12转动锁舌121的U型口到图3所示状态时，车辆发动机盖被锁止，当锁舌121的U型口顺时针转动到一定角度时，车辆发动机盖被解锁。释放机构11用于控制转动机构12的解锁动作，锁状态传感器13用于读取转动机构12的锁止状态或解锁状态，从而获取机盖锁1的锁止和解锁状态即车辆发动机盖的锁止和解锁状态，接触式动作传感器14读取客户的动作信息，来判断客户的开启意图，释放机构弹簧15和转动机构弹簧16都是用于对释放机构11/转动机构12的回位，释放机构铆钉17是用于将释放机构11及释放机构弹簧15安装在锁体19上，同理转动机构铆钉18用于将转动机构12和转动机构弹簧16安装在锁体19上，锁体19为锁的各部分提供安装本体。
执行机构2接收处理器3的信息对机盖锁1提供相关的操作，所述执行机构2包括拉索21、执行器22。拉索21直接和机盖锁1的释放机构11相连接，可以采用各种连接方式，如球头连接或者柱体连接等。执行器22控制拉索21的动作，两者之间的连接可以采用各种连接方式，如球头连接或者柱体连接等。
优选的，本***同时具有机械的开启方式，设计有机械拉手23，用于备用，机械拉手23可根据项目需求进行取舍。
优选的，机械拉手23和释放机构11通过拉索21上的分支24进行连接，也可以根据实际情况设计为独立拉索的形式。
处理器3读取锁状态传感器13和接触式动作传感器14或摄像装置或红外检测装置的各种信号，通过本发明的解锁方法处理分析用户的解锁意图，并将操作指令发送到执行器22。
如图5所示，当转动机构12处于解锁状态时，转动机构上的第二凸块122压到锁状态传感器13上的簧片131，产生解锁信号。如图3所示，当转动机构12处于锁止状态时，锁状态传感器13处于自由状态。从而***可以根据锁状态传感器13的状态判定车辆发动机盖***的开关状态。
如图4所示，当转动机构12处于锁止状态，用户对车辆发动机盖进行按压时，转动机构12在按压作用下往下转动，第一凸块123对接触式动作传感器14上的簧片141进行按压，产生一个按压动作信号，当按压完成，转动机构12在转动机构弹簧16的作用下归位到锁止状态，用户的每一次按压，对应产生一个按压动作信号。
如图6所示为本发明最佳实施例的工作流程图，包括：
步骤S601，如果整车解锁，则执行步骤S602，否则结束；
步骤S602，判断是否挂泊车档位，如果是执行步骤S603，否则结束；
步骤S603，判断车辆发动机盖的开关状态，如果是关闭状态，则执行步骤S604，否则结束；
步骤S604，获取接触式动作传感器的动作信号，当有用户按压车辆发动机盖时，动作信号为按压信号；
步骤S605，判断动作信号是否为预设的解锁动作信号，如果是，执行步骤S606，否则结束；
步骤S606，对车辆发动机盖解锁。
具体来说，在处理器3中预先设定用户解锁动作信号，并进行存储，用于用户动作识别。本实施例采取对按压动作采用时间判断，即在0.2秒到2秒内若连续读取到两次按压动作信号，则视为属于解锁动作信号，只读取到一次按压动作信号，或者读取到的两次按压动作信号间隔时间过短，或者读取到的两次按压动作信号时间间隔过长，都视为非解锁动作信号。一方面让用户有足够的便利性，同时又避免各种误触发操作。
其中，解锁动作信号可以由用户自行设置，例如设置要多少次按压等。
需要指出的是，上述参数仅为说明使用，并不能因此而理解为对本发明专利范围的限制。
同时，本实施例对整车的解锁信号和泊车的状态进行读取，只有在用户对整车解锁，并且车辆处于泊车状态才能实现本解锁方法，以确保用户的使用安全。
在整车解锁后，并且车辆处于泊车状态时，用户对车辆发动机盖***进行按压，此时车辆发动机盖由于是关闭状态，且检测到整车已经解锁，车辆也处于泊车状态，因此锁状态传感器13输出信号为关闭信号，由于用户按压车辆发动机盖时，转动机构12在用户按压作用下发生转动，第二凸块122对接触式动作传感器14上的簧片141进行按压从而产生动作信号，当用户连续进行两次按压动作时，接触式动作传感器14产生两个按压动作信号，处理器3读取到动作信号后，对两次动作信号进行时间分析，若符合0.2秒到2秒的规则，则***判定此次按压动作组合为用户解锁动作信号，处理器3则发出解锁指令到执行机构22，执行机构22收到解锁指令后，则拉动拉索21，从而将释放机构11拉动到释放状态，进而使转动机构12在弹簧16的作用下，进行解锁。
当车辆处于非解锁状态或者未处于泊车状态时，***不读取接触式动作传感器14的信号，因而避免各种安全问题。
当车辆发动机盖处于解锁状态时，由于已经处于解锁状态，不存在需要再解锁的需求，***也不读取接触式动作传感器14的信号。

动作触发模块701，用于：获取动作传感器发送的动作信号，执行动作信号判断模块702；
动作信号判断模块702，用于：如果接收到的动作信号匹配预设的解锁动作信号，则执行解锁模块703，否则不执行解锁模块703；
