Description
本申请涉及车联网技术领域，特别涉及一种车辆解锁方法及车辆解锁系统。
随着经济的快速发展及人民生活水平的不断提高，汽车已逐步成为大多数人出行的代步工具。现有汽车的车门锁一般采用机械钥匙开关锁、遥控钥匙开关锁两种方式。这两种车门锁都需要用户随身携带车钥匙才能对汽车解锁。
但在现实生活中，用户可能都会遇到忘记携带车钥匙或车钥匙丢失而导致无法对汽车进行解锁的情况。此时，用户就不得不额外花费时间去寻找车钥匙，这不仅会浪费用户的时间，还可能影响用户的日程安排，给用户带来极大的不便。
发明内容
本申请部分实施例的目的在于提供一种车辆解锁方法及车辆解锁系统，使得用户无需车钥匙就可对车辆解锁，从而克服用户因忘记携带车钥匙或车钥匙丢失而无法对车辆解锁的缺陷，方便用户的用车。
本申请的一个实施例提供了一种车辆解锁方法，包括：在车辆处于锁定状态时通过距离探测装置检测是否存在物体位于预设解锁范围内；在判定存在物体位于预设解锁范围内时，在车辆外表面上显示人机交互界面；接收通过人
机交互界面输入的解锁信息，并将解锁信息与预设的解锁信息匹配；在匹配成功时，解锁车辆。
本申请实施例还提供了一种车辆解锁系统，包括，控制装置、距离探测装置及人机交互装置；控制装置用于在车辆处于锁定状态时，启动距离探测装置；距离探测装置用于检测是否存在物体位于预设解锁范围内；人机交互装置用于在判定存在物体位于预设解锁范围内时，在车辆外表面上显示人机交互界面；控制装置还用于在接收到通过人机交互界面输入的解锁信息时，将解锁信息与预设的解锁信息匹配，并在匹配成功时，解锁车辆。
本申请实施例相对于现有技术而言，在车辆处于锁定状态时，自行启动设置在车辆上的距离探测装置，并在检测到预设解锁范围内有物体时，在车辆外表面显示供输入解锁信息的人机交互界面，使得用户无需车钥匙便可对车辆解锁，克服了用户因忘记带车钥匙或车钥匙丢失而无法使用车辆的缺陷，极大地方便了用户的用车。
另外，通过距离探测装置检测是否存在物体位于预设解锁范围内包括：控制距离探测装置向车辆以外区域发射探测信号；在接收到从物体反射回来的探测信号时，计算距离探测装置与物体之间的距离；在所述距离在预设解锁范围内时，判定物体位于预设解锁范围内。提供了一种判断预设解锁范围内是否存在物体的方法。
另外，车辆解锁方法还包括：在解锁信息与预设的解锁信息匹配不成功时，锁定人机交互界面；在锁定时长达到预设时长时，解锁人机交互界面。在解锁失败后，需要一定的延时才充许继续输入，有助于提高车辆的安全性。
另外，车辆解锁方法还包括：在判定车辆处于锁定状态之后且在检测是
否存在物体位于预设解锁范围内之前，判断车辆是否处于熄火状态；在判定车辆处于熄火状态时，再执行控制距离探测装置向车辆以外区域发射探测信号。有利于防止车辆在行驶过程中，因检测到车辆处于锁定状态而启动距离传感器造成误判、引起无谓的电浪费。
另外，车辆解锁方法还包括：在判定存在物体位于预设解锁范围内之后，判断物体是否为车辆的用户。确定当前的物体是否是用户，有利于降低误判率。
另外，车辆解锁方法还包括：在判定存在物体位于预设解锁范围内之后，判断距离探测装置在预设的时间段内，是否持续接收到与距离探测装置之间的距离在预设的解锁范围内的物体反射回来的探测信号；在判定距离探测装置在预设的时间段内，持续接收到与距离探测装置之间的距离在预设的解锁范围内的物体反射回来的探测信号时，再执行在车辆外表面上显示人机交互界面。有助于降低物体短暂经过距离探测装置的探测范围而引起误判的情况。
另外，车辆解锁方法还包括：在解锁人机交互界面后，更新人机交互界面上显示的解锁模式；其中，更新的解锁模式的安全等级高于更新前的解锁模式的安全等级。更换解锁模式，有助于提高车辆的安全性。
另外，更新的解锁模式为更新前的解锁模式与至少一种更新前未出现过的解锁模式的组合。在原有的解锁模式上增加新的解锁模式，有利于增大解锁的难度，增加车辆的安全性。
另外，显示装置内嵌于车外壳中，并将人机交互界面显示在车外壳上。提供一种显示装置的安装位置。

为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请部分实施例进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
本申请第一实施例涉及一种车辆解锁方法。具体流程如图1所示。
步骤101：判断车辆是否处于锁定状态。若是，则进入步骤102；若否，则结束流程。
本实施例可通过检测车辆开锁落锁信号，来判断当前车辆是否处于锁定状态。具体而言，车辆在解锁状态及锁定状态时，开锁落锁信号的电平是不同的。一般来说，解锁状态时，开锁落锁信号为持续高电平，锁定状态开锁落锁信号为持续低电平。因此，可通过检测当前开锁落锁信号的电平高低，来判断车辆是否处于锁定状态。
在实际应用中，也可通过判断是否接收到车辆上锁信号来判断车辆是否处于锁定状态。或者，通过检测车辆的锁定装置是否启动来判断车辆是否处于锁定状态。特殊地，对于设置了可隐藏式车门把手的车辆而言，当车辆锁定时，车门把手收回；当车辆解锁时，车门把手弹出。因此，对于设置了可隐藏式车门把手的车辆，也可通过检测当前车门把手的位置，来判断当前车辆是否处于锁定状态。
接下来的步骤102至105，将具体说明如何通过距离探测装置判断是否存在物体位于预设解锁范围内，具体如下：
步骤102：控制设置在车辆上的距离探测装置向车辆以外区域发射探测信号。
该距离探测装置可以是车载雷达(发射的探测信号是超声波)，也可以是光学式距离探测设备，如红外距离传感器(发射的探测信号是红外线)。考虑到用户最大可能站立的位置是车门附近，因此，在判定车辆处于锁定状态后，可优先启动预先安装于车门处的距离探测装置。然并不以此为限，在实际应用中，在启动安装于车门处的距离探测装置的同时，也可启动安装于车身其它位置处的距离探测装置。
步骤103：判断是否接收到从物体反射回来的探测信号。若是，则进入步骤104；若否，则返回步骤103。
距离探测装置一般包括探测信号发射管及探测信号接收管，探测信号接收管可用于接收被物体反射回来的探测信号。本步骤中可通过检测探测信号接收管是否接收到探测信号，来判断探测信号发射的范围内是否有物体(包括人)。
步骤104：计算距离探测装置与物体之间的距离。
距离探测装置在接收到被物体反射回来的探测信号时，可根据探测信号从发射到被物体反射回来的时间以及探测信号的传输速度，来计算距离探测装置与物体之间的距离。
步骤105：判断该距离是否在预设的解锁范围内。若是，则进入步骤106；若不是，则结束流程。
为了减少因行人路过车辆或其他物体(如旁边停的车辆、建筑物)位于车辆附近而造成误判，本实施例可将解锁范围设置在10cm至20cm之间。在实际应用中，也可根据车辆的实际情况，灵活设置这一解锁范围，本实施例对此不做限制。
步骤106：在车辆外表面上显示人机交互界面。
该外表面可以是车挡风玻璃(包括侧挡风玻璃、前挡风玻璃及后挡风玻璃)外表面(即挡风玻璃外侧)，也可以是车门外表面、车盖(包括车前盖、车后盖)外表面等。
该人机交互界面上可显示预设的解锁模式。该预设的解锁模式可以为密码、指纹识别、人脸识别、虹膜识别等。
在设置人机交互界面显示解锁模式时，可以设置人机交互界面单一地显示一种解锁方式，如只显示要求用户输入密码的密码解锁模式，或只显示要求用户输入指纹的指纹识别解锁模式；也可设置人机交互界面以组合地形式显示多种解锁方式，如显示既要求用户输入密码、又要求用户输入指纹的密码与指纹识别复用的解锁模式。
步骤107：接收通过人机交互界面输入的解锁信息，判断该解锁信息与预设的解锁信息是否匹配。若是，则进入步骤108；若否，则返回步骤107。
在预先设置人机交互界面显示解锁模式时，就可要求用户设定与该显示的解锁模式匹配的解锁信息。例如，设置人机交互界面显示的解锁模式为密码解锁模式，就可要求用户预设置解锁密码，并将用户预设置的解锁密码存储至相应的数据库中。若设置人机交互界面显示的解锁模式包括指纹识别、虹膜识别或人脸识别等解锁方式，则可预先采集用户相应的生物特征，并存储至相应的数据库中。
在接收到通过人机交互界面输入的解锁信息时，则可将该输入的解锁信息与数据库中存储的解锁信息进行匹配。
步骤108：解锁车辆。
在匹配成功时，可向车辆的锁定装置或门锁驱动器发送解锁指令，触发
锁定装置或门锁驱动器打开车门锁。特殊地，如上文所述，对于设置了可隐藏式车门把手的车辆而言，可通过向车辆的锁定装置或门锁驱动器发送解锁指令，触发锁定装置或门锁驱动器向外弹出车门把手。
在实际应用中，为提升车辆的安全性，还可将车辆的控制装置(可以是处理器)与用户的手机号预先绑定。在接收到的解锁信息与预设的解锁信息匹配成功时，可先向预先绑定的手机号发送确认信息，确认信息中可包括解锁时间、解锁地点等信息。待接收到该预先绑定的手机号反馈的确定信息时，再打开车门的车门锁。
也可以设置在接收到的解锁信息与预设的解锁信息匹配成功时，一边向预先绑定的手机号发送确认信息，一边向车辆的锁定装置或门锁驱动器发送解锁指令，触发锁定装置或门锁驱动器仅打开驾驶座对应的车门的车门锁。待接收到该预先绑定的手机号反馈的确定信息后，再打开其它车门的车门锁。这样既可避免用户因忘记带手机而无法对车辆解锁的问题，又可以时时了解自己车辆的状态。
本实施例相对于现有技术而言，在车辆处于锁定状态时，自行启动设置在车辆上的距离探测装置，并在检测到预设的解锁范围内有物体时，在车辆外表面显示供输入解锁信息的人机交互界面，使得用户无需车钥匙便可对车辆解锁，克服了用户因忘记带车钥匙或车钥匙丢失而无法使用车辆的缺陷，极大地方便了用户的用车。
本申请第二实施例涉及一种车辆解锁方法。本实施例在第一实施例的基础上，对接收到的解锁信息与预设的解锁信息匹配不成功的情况，做进一步改
进。本实施例的具体流程如图2所示。
其中，步骤201至208与第一实施例的步骤101至108大致相同，在此不再赘述。本实施例在第一实施例的基础上，增加了步骤209、210及211。
步骤209：锁定人机交互界面。
在接收到的解锁信息匹配不成功时，可向提供人机交互界面的人机交互装置发送锁定指令，触发人机交互装置锁定当前的人机交互界面，阻止相关人员继续输入或修改解锁信息。
步骤210：判断锁定时长是否达到预设时长。若是，则进入步骤211，若否，则返回步骤210。
在锁定人机交互界面的同时，可通过启动计时器记录锁定的时长，再实时将记录的时长与预设的时长进行比较，以判断锁定时长是否达到预设时长。或者，在锁定人机交互界面的同时，即用该预设时长作为计时起点、将0作为计时终点进行倒计时，通过判断是否到达计时终点，来判断锁定时长是否达到预设时长。
步骤211：解锁人机交互界面。
在锁定时长达到预设时长时，向人机交互装置发送解除锁定的指令，触发人机交互装置解除当前人机交互界面的锁定状态，恢复人机交互界面的输入功能。此时，相关人员可重新通过人机交互面界面输入解锁信息。
另外，值得一提的是，为提升车辆的安全性，本实施例还可预先设定解锁次数，如只充许有3次解锁的机会。此后，在步骤207中，当判定接收到的解锁信息与预设的解锁信息不匹配时，可先判断当前的解锁次数是否达到预设的次数。若已达到预设的次数，则可直接关闭人机交互界面并启动报警装置；
若还未达到预设的次数，则再执行步骤209。
本实施例相对于第一实施例而言，在接收到的解锁信息与预设的解锁信息匹配不成功时，经过一定的延时后，才充许用户再次输入解锁信息，有助于进一步提升车辆的安全性。
本申请第三实施例涉及一种车辆解锁方法。本实施例在第一实施例或第二实施例的基础上，对启动距离探测装置的条件，做进一步改进。主要改进之处在于，在控制设置在车辆上的距离探测装置向车辆以外区域发射探测信号之前，还判断车辆是否处于熄火状态。
本实施例的具体流程如图3所示，值得一提的是，图3是以第二实施例为基础的示意图，在实际应用中，本实施例也可以作为在第一实施例基础上的改进，可以达到相同的技术效果。
其中，步骤301、303至312与第二实施例的步骤201至211大致相同，在此不再赘述。本实施例在第二实施例的基础上，增加了步骤302。
步骤302：判断车辆是否处于熄火状态。若是，则进入步骤303；若否，则结束流程。
一般来说，车辆在行驶过程中，也会处于锁定状态。因此，为了防止车辆在行驶过程中，因检测到车辆处于锁定状态而启动距离传感器造成误判、引起无谓的电浪费，本实施例可在启动距离传感器之前，进一步判断当前车辆是否处于熄火状态。
本实施例可通过判断发动机是否关闭来判断车辆是否处于熄火状态，若关闭可判定车辆处于熄火状态，若未关闭，则判定车辆未处于熄火状态。也可
通过车辆ACC信号线的电平来判断车辆是否处于熄火状态。具体而言，在车辆点火后，车辆ACC信号线为持续高电平；在车辆熄灭后，车辆ACC信号线为持续低电平，因此，车辆的控制装置可通过车辆ACC信号线的电平来来判断车辆是否处于熄火状态。
值得一提的是，本实施例中，先判断车辆是否处于锁定状态，在判定车辆处于锁定状态后，再判断车辆是否处于熄火状态，但在实际应用中，也可以先判断车辆是否处于熄火状态，在判定车辆处于熄火状态后，再判定车辆是否处于锁定状态。
本实施例相对于第一实施例或第二实施例而言，除了判断车辆是否处于锁定状态，还会判断车辆是否处于熄火状态，并在两个条件都满足(车辆处于锁定及熄火的状态)时，才启动距离探测装置，有助于进一步降低误判率。
本申请第四实施例涉及一种车辆解锁方法。本实施例在第二或第三实施例的基础上，对解锁人机交互界面后，人机交互界面上显示的解锁模式，做了进一步改进。主要改进之处在于：本实施例中，在解锁人机交互界面后，会更新人机交互界面上显示的解锁模式。
本实施例的具体流程如图4所示。值得一提的是，图4是以第三实施例为基础的示意图，在实际应用中，本实施例也可以作为在第二实施例基础上的改进，可以达到相同的技术效果。
其中，步骤401至412与第三实施例的步骤301至312相同，在此不再赘述。本实施例在第三实施例的基础上，增加了步骤413。
步骤413：更新人机交互界面上显示的解锁模式。
为提升车辆的安全性，可设置人机交互界面每次显示不同的解锁模式。例如，第一次显示的指纹识别解锁模式，若用户输入的指纹与预先存储的指纹不匹配，则第二次就可显示除指纹识别解锁模式之外的其它解锁模式，如密码解锁模式或者密码与指纹识别复用的解锁模式等。
在实际应用中，还可逐渐增大显示的解锁模式的安全等级，以进一步增强车辆的安全性。具体而言，可对存储的解锁信息(该存储的解锁信息由用户提前输入)进行分析，获取对应的安全等级，然后按照安全等级由低到高的顺序显示对应的解锁模式，即保证更新的解锁模式的安全等级高于更新前的解锁模式的安全等级。例如，存储的解锁信息为密码、指纹及人脸特征。通过分析得出，该密码设置的最为复杂，安全级别最高；人脸特征次之，指纹的安全级别最低。则至少可设置三个安全等级的解锁模式，从高到低依次为：密码解锁模式、人脸识别解锁模式、指纹识别解锁模式。考虑到两两解锁模式的组合及三个解锁锁模式的组合，安全等级更佳，因此，还可在前述设置的三个安全等级的基础上进一步增加组合式的解锁模式。
可选地，为保证更新的解锁模式的安全等级高于更新前的解锁模式的安全等级，还可设定更新的解锁模式为更新前的解锁模式与至少一种更新前未出现过的解锁模式的组合。即通过在前次显示的解锁模式的基础上增加新的解锁模式，来提高车辆的安全性。例如，当前显示的解锁模式是密码解锁模式，若用户输入的指纹与预先存储的指纹不匹配，则第二次就可在是密码解锁模式的基础上增加新的解锁模式，如第二次可显示密码与指纹识别复用的解锁模式。
需要说明的是，若要限定用户的解锁次数(如只给用户三次解锁的机会)，则设定的解锁次数要小于或等于设置的安全等级的级数。例如，通过对存储的
解锁信息进行分析后得出，可设置三个等级的解锁模式，则预设的解锁次数要小于或等于三。
本实施例相对于第二或第三实施方式而言，在解锁人机交互界面后，更新人机交互界面上显示的解锁模式，增大了随机性，有利于提高车辆的安全性。
本申请第五实施例涉及一种车辆解锁方法。本实施例在第一、第二、第三或第四实施例的基础上，对显示人机交互界面的条件，做了进一步改进。主要改进之处在于：本实施例中，在判定物体与距离探测装置之间的距离在预设的解锁范围内之后，还会判断该物体是否为用户。
本实施例的具体流程如图5所示。值得一提的是，图5是以第四实施例为基础的示意图，在实际应用中，本实施例也可以作为在第一、第二或第三实施例基础上的改进，可以达到相同的技术效果。
其中，步骤501至506、508至514与第四实施例的步骤401至413相同，在此不再赘述。本实施例在第四实施例的基础上，增加了步骤507。
步骤507：判断该物体是否为车辆的用户。若是，则进入步骤508；若否，则结束流程。
具体而言，本实施例可预先存储用户的头像，这里所说的用户可以是授权使用该车辆的所有的人。在判定物体的距离与距离探测装置之间的距离在预设的解锁范围内时，可启动摄像装置，获取物体的图像，并将获取的图像与预存的用户的图像进行匹配，并在匹配成功时，判定该物体为用户。
可选地，也可以提前约定某种手势或某段语音指令为判定其为车辆的用户的标准。具体而言，可预先选定一种手势或一段语音，作为判断用户的根据，
并存储至相应的数据库中。在判定物体的距离与距离探测装置之间的距离在预设的解锁范围内时，可启动摄像装置或语音录入装置。若摄像装置拍摄到对应的手势或者语音录入装置录入对应的语音，则判定该物体为用户。
本实施例相对于第一、第二、第三或第四实施例而言，对显示人机交互界面的条件做了进一步加强，有助于进一步降低误判率，增加车辆的安全性。
本申请第六实施例涉及一种车辆解锁方法。本实施例在第一、第二、第三或第四实施例的基础上，对显示人机交互界面的条件，做了进一步改进。主要改进之处在于：本实施例中，在判定物体与距离探测装置之间的距离在预设的解锁范围内之后，还会判断距离探测装置在预设的时间段内，是否持续接收到与距离探测装置之间的距离在预设的解锁范围内的物体反射回来的探测信号。
本实施例的具体流程如图6所示。值得一提的是，图6是以第四实施例为基础的示意图，在实际应用中，本实施例也可以作为在第一、第二或第三实施例基础上的改进，可以达到相同的技术效果。
其中，步骤601至606、608至614与第四实施例的步骤401至413相同，在此不再赘述。本实施例在第四实施例的基础上，增加了步骤607。
步骤607：判断距离探测装置在预设的时间段内，是否持续接收到与距离探测装置之间的距离在预设的解锁范围内的物体反射回来的探测信号。若是，则进入步骤608；若否，则结束流程。
考虑到行人或其它物体经过车辆而可能造成误判的情况，本实施例可预设一时间段，在判定物体与距离探测装置之间的距离在预设的解锁范围内时，
开始计时。在计时时长达到该预设时间段期间，判断距离探测装置是否持续接收到与距离探测装置之间的距离在预设的解锁范围内的物体反射回来的探测信号，若距离探测装置持续接收到与距离探测装置之间的距离在预设的解锁范围内的物体反射回来的探测信号，则判定当前的物体为用户。
本实施例相对于第一、第二、第三或第四实施例而言，对显示人机交互界面的条件做了进一步加强，有助于进一步降低误判率。
本申请第七实施例涉及一种车辆解锁系统。如图7所示，该车辆解锁系统可包括控制装置71、距离探测装置72及人机交互装置73。距离探测装置72及人机交互装置73均与控制装置71通信连接。
控制装置71用于在车辆处于锁定状态时，启动距离探测装置72。
一般来说，解锁状态时，开锁落锁信号为持续高电平，锁定状态开锁落锁信号为持续低电平，因此，控制装置71可通过检测车辆开锁落锁信号，来判断当前车辆是否处于锁定状态。在判定车辆处于锁定状态时，控制装置71即可向距离探测装置71发送启动指令。
距离探测装置72在接收到启动指令时，即可启动，向车辆以外区域发射探测信号，并在接收到从物体反射回来的探测信号时，计算距离探测装置与物体之间的距离。
该距离探测装置可以是车载雷达(发射的探测信号是超声波)，也可以是光学式距离探测设备，如红外距离传感器(发射的探测信号是红外线)。在接收到被物体反射回来的探测信号时，距离探测装置可根据探测信号从发射到被物体反射回来的时间以及自身的速度，来计算距离探测装置与物体之间的距
离。
人机交互装置73用于在距离探测装置与物体之间的距离在预设的解锁范围内时，在车辆外表面上显示人机交互界面。
具体而言，控制装置71可在距离探测装置72计算出其与物体之间的距离后，从距离探测装置72读取该距离，并将该读取的距离与预设的解锁范围比较，以判断该距离是否在预设的解锁范围内。若控制装置71判定该距离在预设的解锁范围内，则向人机交互装置73发送显示人机交互界面的指令，触发人机交互装置73在车辆外表面上显示人机交互界面。
该人机交互界面上可显示预设的解锁模式。该预设的解锁模式可以为以下任意一种或以下任意组合：密码、指纹识别、人脸识别、虹膜识别。用户可根据当前人机交互界面上显示的解锁模式，输入对应的解锁信息。
控制装置71还用于在接收到通过人机交互界面输入的解锁信息时，将该解锁信息与预设的解锁信息匹配，并在匹配成功时，解锁车辆。
在匹配成功时，控制装置71可向车辆的锁定装置或门锁驱动器发送解锁指令，触发锁定装置或门锁驱动器打开车门锁。
在匹配不成功时，人机交互界面上可显示提示框，提醒用户当前输入的解锁信息错误，请用户重新输入解锁信息。在限制解锁次数的情况下，还可提醒用户当前是第几次输入解锁信息，还剩下几次解锁机会等信息。
值得一提的是，为了提升车辆的安全性，还可设置控制装置在匹配不成功时，向人机交互装置发送锁定指令，触发人机交互装置锁定人机交互界面，阻止用户继续输入或修改解锁信息；并在锁定时长达到预设时长时，向人机交互装置发送解锁指令，触发人机交互装置解锁人机交互界面。
下面将以安装了隐藏式车门把手的车辆为例具体说明本实施例：
具体而言，安装了隐藏式车门把手的车辆，在车辆锁定时，车门把手收回；在车辆解锁时，车门把手弹出。因此，控制装置可通过检测当前车门把手的位置，来判断当前车辆是否处于锁定状态。
当控制装置判定当前车辆处于锁定状态时，即可向距离探测装置发送启动指令，触发距离探测装置向外发射探测信号，如图8所示。值得一提的是，图8示出的距离探测装置安装在车门上，但在实际应用中并不以此为限，可根据车辆的实际情况灵活设置距离探测装置的位置。
在距离探测装置接收到从物体反射回来的探测信号，并计算出距离探测装置与物体之间的距离后，控制装置可读取该距离，并判断该距离是否在预设的解锁范围内。在判定该距离在预设的解锁范围内时，控制装置即可触发人机交互装置在车辆外表面显示人机交互界面，如图9、10所示。图9、10中人机交互界面显示在侧挡风玻璃上，显示的解锁模式是密码解锁模式及指纹识别解锁模式。这种情况下可要求用户在两种解锁模式下选择一种解锁模式，输入相应的解锁信息进行解锁；也可以既要求用户输入对应的密码，又要求用户输入指纹，以提高车辆的安全性。值得一提的是，本实施例可将指纹采集装置安装在车辆显示人机交互界面的位置处，例如，本例中，人机交互界面显示在侧挡风玻璃上，那么指纹采集装置就可内置于侧挡风玻璃内。该指纹采集装置可以采用光学、电容或超声波式的指纹采集传感器。
在接收到通过人机交互界面输入的解锁信息后，控制装置将该解锁信息与预存的解锁信息匹配，并在匹配成功时，向车辆的锁定装置或门锁驱动器发送解锁指令，触发锁定装置或门锁驱动器向外弹出车门把手，如图11所示。
本实施例相对与现有技术而言，在车辆处于锁定状态时，自行启动设置在车辆上的距离探测装置，并在检测到预设的解锁范围内有物体时，在车辆外表面显示供输入解锁信息的人机交互界面，使得用户无需车钥匙便可对车辆解锁，克服了用户因忘记带车钥匙或车钥匙丢失而无法使用车辆的缺陷，极大地方便了用户的用车。
本实施例为与以上提供的车辆解锁方法实施例相对应的系统实施例，本实施例可与以上提供的车辆解锁方法实施例互相配合实施。以上提供的车辆解锁方法实施例中提到的相关技术细节在本实施例中依然有效，为了减少重复，这里不再赘述。相应地，本实施例中提到的相关技术细节也可应用在以上提供的车辆解锁方法实施例中。
本申请第八实施例涉及一种车辆解锁系统。本实施例在第七实施例的基础上，对人机交互装置进行扩展。
如图12所示，人机交互装置包括显示装置121及触控装置122。显示装置121用于显示人机交互界面，其可以是LCD显示屏或LED显示屏。触控装置122用于供用户输入解锁信息，其可以是电容或电阻式触摸板。
本实施例中，显示装置121可内嵌于车外壳中，在接收到来自控制装置的显示人机交互界面的指令时，即可在其安装位置对应的车辆外表面上显示人机交互界面。本实施例所说的车外壳包括车挡风玻璃(包括侧挡风玻璃、车前挡风玻璃及车后挡风玻璃)、车门、车前盖及车后盖。当显示装置121内嵌于车辆的侧挡风玻璃中时，即可将人机交互界面显示在侧挡风玻璃上。
触控装置可外贴于显示该人机交互界面的车辆外表面处，以供用户操作
人机交互界面。触控装置也可内置于车辆显示该人机交互界面的位置对应的车外壳内。
本实施例相对于第七实施例而言，对显示装置及触控装置的安装位置做了进一步扩展。
本申请第九实施例涉及一种车辆解锁系统。本实施例在第七实施例的基础上，对人机交互装置进行扩展。本实施例与第八实施例大致相同，主要区别之外在于，第八实施例中，显示装置121内嵌于车外壳中；而本实施例中，显示装置121可置于车辆内部。
具体而言，本实施例中，显示装置121可置于车外壳包围的空间内，在接收到来自控制装置的显示人机交互界面的指令时，可显示人机交互界面，并将显示的人交互界面以投影的方式显示在车辆的侧挡风玻璃上。
本实施例相对于第八实施例而言，提供了另一种安装显示装置的位置。
本领域的普通技术人员可以理解，上述各实施例是实现本申请的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本申请的精神和范围。
