无论车主设备端还是好友设备端再次与车端进行匹配连接时，直接通过目标设备端的蓝牙模块和车端的蓝牙模块204，使目标设备端和车端进行快速匹配连接。并且，在目标设备端与车端进行连接之后，车端的解锁车门过程均是一致的。Whether the owner's device or the friend's device is connected to the car again, the target device and the car are quickly matched and connected directly through the Bluetooth module of the target device and the
目标设备端与车端再次匹配连接的过程是，通过车端的蓝牙模块204广播式发送匹配标志位。目标设备端的蓝牙模块一直处于扫描接收数据模式。在目标用户携带的目标设备端处于蓝牙模块设定范围内，目标设备端的蓝牙模块接收到车端发送的匹配标志位。其中，蓝牙模块设定范围为车端的蓝牙模块204和目标设备的蓝牙模块能相互通信的距离范围，如蓝牙模块设定范围为0-15米或0-30米，其具体范围数值可根据实际需求而设置。The process of matching and connecting the target device end and the car end again is to broadcast the matching flag bit through the
目标设备端接收到匹配标志位后，目标设备端判断匹配标志位是否为预设有效标志位，预设有效标志位为预存的车端密钥的有效标志位。若匹配标志位为预设有效标志位，则通过存储至目标设备端的车端密钥对匹配标志位进行验证，再发送连接请求至车端，与车端进行匹配连接。在接收到目标设备端根据匹配标志位发送的连接请求之后，根据连接请求，发送连接响应信号至目标设备端，与目标设备端进行匹配连接。如此，目标用户靠近整车后，车端与目标用户的目标设备端实现自动匹配连接。After the target device receives the matching flag, the target device judges whether the matching flag is a preset valid flag, and the preset valid flag is the valid flag of the pre-stored vehicle key. If the matching flag is a preset valid flag, the matching flag is verified by the car-end key stored in the target device, and then a connection request is sent to the car to perform a matching connection with the car. After receiving the connection request sent by the target device according to the matching flag bit, a connection response signal is sent to the target device according to the connection request to perform a matching connection with the target device. In this way, after the target user approaches the complete vehicle, the vehicle end and the target user's target device end will automatically match and connect.
若匹配标志位未为预设有效标志位，则目标设备端不会与车端进行匹配连接，目标设备端也不会向车端发送连接请求，继续处于扫描接收数据模式。If the matching flag is not a preset valid flag, the target device will not perform a matching connection with the car, and the target device will not send a connection request to the car, and will continue to be in the scanning and receiving data mode.
在本实施例中，由于目标设备端与车端在首次连接的过程中，二者相互交换各自的密钥，完成双方的身份识别和认证。目标设备端与车端再次连接的过程中，目标设备端直接通过预存的车端密钥验证接收到的匹配标志位，实现目标设备端与车端的自动匹配连接，为后续解锁车门操作提高效率。这样，还避免了车主或目标用户手动使用车钥匙或电子钥匙设备，主动连接车端，节约了时间成本，便于车主或目标用户操作。In this embodiment, since the target device end and the car end are connected for the first time, they exchange their respective keys to complete identity recognition and authentication of both parties. During the reconnection process between the target device and the car, the target device directly verifies the received matching flag through the pre-stored car key, realizing the automatic matching and connection between the target device and the car, and improving the efficiency for the subsequent unlocking of the car door. In this way, it also prevents the car owner or target user from manually using the car key or electronic key device to actively connect to the car end, which saves time and cost, and is convenient for the car owner or target user to operate.
在与目标设备端进行匹配连接之后，执行步骤S101，获取与目标设备端的当前距离，其中，目标设备端包括车主设备端和车主设备端的好友设备端。After matching and connecting with the target device, step S101 is executed to obtain the current distance to the target device, wherein the target device includes the vehicle owner's device and the friend device of the vehicle owner's device.
具体来讲，在目标设备端与车端进行匹配连接后，通过车端的UWB模块203和UWB技术对目标设备端进行精准定位，获取目标设备端距离车端的当前距离。Specifically, after the target device is matched and connected to the vehicle, the target device is precisely positioned through the
接着，执行步骤S102，在检测到当前距离位于预设距离范围时，唤醒车端的语音识别模块202。Next, step S102 is executed to wake up the
具体来讲，预设距离范围为目标设备端与车端之间的设定距离范围，用于实现唤醒车端的语音识别模块202的条件。预设距离范围可根据实际需求而设置，如预设距离范围设置为2-5米或1-3米。Specifically, the preset distance range is the set distance range between the target device end and the vehicle end, and is used to realize the condition for waking up the
举例来说，假设预设距离范围为2-3米，在检测到当前距离为3米时，车端唤醒语音识别模块202，以使语音识别模块202准备接收目标用户或车主的语音，并识别验证语音的身份。For example, assuming that the preset distance range is 2-3 meters, when the current distance is detected to be 3 meters, the vehicle end wakes up the
在本实施例中，在目标设备端与车端匹配连接后，获取并通过判断目标设备端距离车端的当前距离是否位于预设距离范围。若是，则唤醒语音识别模块202，以通过UWB技术能准确地判断目标用户的位置距离，使语音识别模块202准备识别工作。这样，实现了车主设备端与车端的快速匹配，多次完成目标用户身份验证，便捷快速地解锁车门，提高车门的解锁效率，便于车主操作和管理车辆，保证用车安全。并且，还避免额外增加唤醒语音识别模块202的器件，如额外设置的物理按键或触摸按键，节省时间和物力成本。In this embodiment, after the target device end is matched and connected with the car end, it is acquired and judged whether the current distance between the target device end and the car end is within a preset distance range. If so, wake up the
然后，执行步骤S103，接收解锁语音，通过语音识别模块202识别解锁语音，并根据识别后的解锁语音，解锁车端的车门。Then, step S103 is executed to receive the unlocking voice, recognize the unlocking voice through the
具体来讲，目标用户在靠近整车的车门后，此时目标设备端与车端已进行匹配连接，且车端的语音识别模块202已被唤醒，目标用户直接说出解锁语音，如说出“开门”的解锁语音。车端的语音识别模块202接收到解锁语音，通过语音识别模块202识别出解锁语音的解锁语音特征。若解锁语音特征与预设语音特征一致，表示此时说话的目标用户的身份与预设语音特征对应的用户的身份是相同的，此时说话的目标用户的身份验证已通过，则通过语音识别模块202识别解锁语音的解锁语义信息，并将解锁语义信息作为识别后的解锁语音。语音识别模块202将识别后的解锁语音通过整车的CAN总线发送到车身控制器201，车身控制器201控制车门正常解锁。车身控制器201通常锁车门时处于休眠状态，在语音控制器被唤醒的同时，车身控制器201也被唤醒，唤醒动作均通过整车CAN总线实现。Specifically, after the target user is close to the door of the vehicle, the target device end and the vehicle end have been matched and connected, and the
以目标用户发出“开门”的解锁语音为例，车端接收到该解锁语音，先通过语音识别模块202判断该解锁语音的解锁语音特征是否与预设语音特征一致。若一致，则通过语音识别模块202识别出该解锁语音的解锁语义信息为“开门”的语音信息，再根据“开门”的解锁信息，打开整车的车门，以使目标用户进入整车中。Taking the unlocking voice of "open the door" issued by the target user as an example, the car end receives the unlocking voice, and first judges whether the unlocking voice feature of the unlocking voice is consistent with the preset voice feature through the
若解锁语音特征与预设语音特征未一致，表示此时说话的目标用户的身份与预设语音特征对应的用户的身份是不同的，此时说话的目标用户的身份验证未通过，则输出车门解锁失败信息，控制车门处于闭锁状态。输出车门解锁失败信息的方式可以是整车的语音播报，也可以是车端发送车门解锁失败提示消息至车主设备端，或是其他根据实际需求而设置的方式。If the unlocking voice feature is not consistent with the preset voice feature, it means that the identity of the target user who is speaking at this time is different from the identity of the user corresponding to the preset voice feature. At this time, the identity verification of the target user who is speaking has not passed, then output the car door Unlock failure information, control the door is locked. The way to output the failure information of the door unlocking can be the voice broadcast of the whole vehicle, or the vehicle end can send the prompt message of the failure of door unlocking to the owner's device end, or other methods can be set according to actual needs.
在本实施例中，通过语音识别方式，识别语音特征，验证目标用户的身份，控制车门解锁，提高车门的解锁效率，便于车主操作和管理车辆，保证用车安全。语音识别方式相比人脸识别和指纹识别，语音识别方式无需手动操作且识别方式较简单，在目标用户不方便继续操作的情形中，如手上有携带物，气候状况不好的情况等情况，语音识别方式更具优势。In this embodiment, voice features are identified through voice recognition, the identity of the target user is verified, and the unlocking of the vehicle door is controlled to improve the unlocking efficiency of the vehicle door, facilitate the operation and management of the vehicle by the vehicle owner, and ensure the safety of the vehicle. Compared with face recognition and fingerprint recognition, the voice recognition method does not require manual operation and the recognition method is relatively simple. In the case where the target user is inconvenient to continue to operate, such as carrying objects on hand or in bad weather conditions, etc. , the voice recognition method is more advantageous.
另外，在车端未接收到目标设备端发送的连接请求的情形下，表示目标设备端没电或电流极低，不能实现目标设备端和车端的蓝牙匹配连接，通过车端的近场通信模块205检测到设定设备，直接解锁车端的车门。设定设备包括但不限于车主的车钥匙、车卡、手机或其他终端设备。唤醒语音识别模块202后，继续执行步骤S103。In addition, when the car end does not receive the connection request sent by the target device end, it means that the target device end has no power or the current is extremely low, and the Bluetooth matching connection between the target device end and the car end cannot be realized. When the setting device is detected, the door at the end of the car is unlocked directly. Setting devices include but are not limited to car keys, car cards, mobile phones or other terminal devices of car owners. After waking up the
目标用户在解锁车门之后，进入整车内，语音识别模块202进入车内工作模式，准备接收车内用户的指令实现相关控制功能，不继续处理车门处语音拾取麦克风的信号输入。其中，车内用户包括目标用户和车内的非目标用户。After the target user unlocks the car door and enters the vehicle, the
目标用户使用整车且下车之后，无需再对目标用户进行身份识别。目标用户离车关车门之后，发出锁车语音。语音识别模块202识别到锁车语音后向车身控制器201发送闭锁车门信息，车身控制器201控制车门上锁关闭。随后语音识别模块202和车身控制器201均转入休眠模式，等待下次被唤醒。After the target user uses the whole vehicle and gets off the vehicle, there is no need to identify the target user. After the target user leaves the car and closes the door, the car lock voice is issued. After the
关于车主设备端和好友设备端的，车主设备端是最高优先级的控制车端的设备，车主设备端可对好友设备端的相关信息进行配置。车主设备端拥有不受限制的所有访问车端配置权限，好友设备端的数量可为多个。Regarding the car owner's device and the friend's device, the car owner's device is the device that controls the car with the highest priority, and the car owner's device can configure the relevant information of the friend's device. The car owner's device has unlimited access to all configurations of the car, and the number of friend's devices can be multiple.
好友设备端在向车端进行注册之后，车端将好友设备端的注册信息发送至车主设备端。车主设备端将好友设备端的注册信息通过显示屏显示，供车主审阅。车主对好友设备端的注册信息进行配置，车主设备端获取到配置信息，并将配置信息发送至车端。其中，配置信息为好友设备端使用车端的权限设置信息，配置信息包括好友设备端的车端密钥的使用期限和使用时间段。After the friend's device registers with the car, the car sends the registration information of the friend's device to the owner's device. The car owner's device side displays the registration information of the friend's device side through the display screen for the car owner to review. The car owner configures the registration information of the friend's device, and the car owner's device obtains the configuration information and sends the configuration information to the car. Wherein, the configuration information is the permission setting information of the friend's device to use the vehicle, and the configuration information includes the usage period and the usage time period of the vehicle key of the friend's device.
车主设备端还能对多个好友设备端进行归类，如设置为“家人”类、“好友”类等。针对不同的类别，车主可以设置不同类别的权限信息，则属于同个类别的好友设备端的权限信息是一致的。The car owner's device can also classify multiple friends' devices, such as setting them as "family" and "friends". For different categories, the car owner can set different categories of permission information, and then the permission information on the devices of friends belonging to the same category is consistent.
好友设备端在使用整车的过程中，如果好友设备端的车端密钥的使用期限即将到期，则通过语音识别模块202发出授权即将过期的提示语音，以提醒好友设备端的用户归还整车或联系车主进行使用期限的续订。车端检测到好友设备端的车端密钥的使用期限过期时，车端的语音识别模块202将好友设备端的预设语音特征删除，表示好友设备端的预设语音特征失效，以使好友设备端不能解锁车门。车端的车身控制器201还将发送好友设备端的预设语音特征已删除的提示信息至车主设备端。并且，好友设备端每次与车端进行匹配连接时，车端的车身控制器201均会向车主设备端发送某个好友设备端正在使用整车的提示信息，以使车主实时掌握好友设备端的用车情况。In the process of using the whole vehicle at the friend's device end, if the service period of the vehicle end key at the friend's device end is about to expire, the
