Detailed ways

The technical solution in this application will be described below with reference to the accompanying drawings.

A typical application scenario where the unlocking method and device provided in the embodiments of the present application can be applied is a car unlocking scene, for example, a scene where a user returns to the vicinity of the vehicle with a terminal device such as a car key or a mobile phone, and is about to unlock the car lock to open a car door or a trunk. . It should be noted that the methods and devices provided in the embodiments of the present application can also be applied to various other application scenarios that require unlocking, such as unlocking of residential house doors/office doors and other doors, unlocking of electrical equipment and other equipment, electric bicycles/electric Various scenarios such as unlocking of vehicles such as scooters. In order to facilitate the understanding of the unlocking method and device provided by the embodiment of the present application, the car unlocking scene is used as an example below to describe the solution provided by the embodiment of the present application, so that implementation solutions in other scenarios can be adaptively obtained.

In order to facilitate the understanding of the improvements made by the solutions provided by the embodiments of the present application, the solutions in the existing related technologies are briefly described first. Taking the car unlocking scene as an example, a non-inductive unlocking solution proposed in the existing related technology, when it is detected that the car key or mobile phone is within a short distance from the vehicle, the vehicle electronic lock will automatically open without the user taking out the car. The key or mobile phone can be used to unlock the door, and the door can be opened directly. The basic principle of this kind of non-inductive unlocking scheme is that the effective communication distance range of the weak antenna (ultra-short-range antenna) is generally relatively small, and it can only sense signals within a small distance range around it, for example, it can sense whether the vehicle is within a range of about 1.5 meters , if yes, the key sends an unlock message, and the user can open the door.

The inventor found in the research process that although the non-inductive unlocking solution reduces user operations, it has the following disadvantages:

On the one hand, the relay attack is a common attack method in the field of communication technology, and the above-mentioned non-sensing unlocking scheme in the related art cannot resist the relay attack. As shown in Figure 1, when the signal amplifier is placed near the vehicle C0 and the terminal equipment UE0 at the same time, the weak signal sent by the vehicle or mobile phone is amplified, so that the car key or mobile phone, as well as the vehicle, will mistakenly think that the other party is within a short distance and open it. Car lock, but the actual signal interaction is to extend the communication distance through the signal amplifier. Therefore, the existing scheme of automatically unlocking the lock without the user's awareness cannot resist relay (signal amplifier) attacks, increases the risk of car theft, and has security problems.

As shown in Figure 2, an auxiliary technical means currently used to resist the problem of relay attacks is to combine the Global Positioning System (Global Positioning System, GPS) or Beidou satellite navigation when locking the car through the terminal equipment UE0 (such as a mobile phone) System (BeiDou Navigation Satellite System, BDS) and other satellite positioning system positioning information for auxiliary judgment. Vehicle location information or mobile phone location information issued by GPS or BDS is obtained by vehicle C1 or terminal equipment UE0 directly communicating with positioning satellite S1, and will not be affected by nearby signal amplifiers, so it can solve the problem of relay attacks. However, in practical applications, the accuracy of GPS or BDS civil positioning services is about ±10 meters, and the range of 10 meters from the vehicle to the mobile phone is still not safe, and there is still the possibility of relay attacks and the risk of theft. In addition, another disadvantage that cannot be ignored is that the above-mentioned non-inductive unlocking scheme in the prior art has no obvious timing to trigger the unlocking. Mobile phones and vehicles need to continuously turn on GPS to obtain positioning, and GPS positioning consumes a lot of power. High power consumption, difficult to practical application. The existing above-mentioned non-inductive unlocking schemes currently lack effective methods to solve the existing relay attack problem.

On the other hand, mobile phones and other terminal devices used for unlocking need to transmit signals (such as Wi-Fi or Bluetooth signals) through the weak antenna of the mobile phone when judging whether the vehicle is nearby. Only the signal transmitted by the weak antenna is received by the vehicle. Only then can it be judged that the vehicle is within a relatively short distance. The weak antenna is not the basic hardware configuration of the mobile phone. The pre-implementation of the mobile phone with the unlocking function requires an additional weak antenna to be installed during the manufacturing process of the mobile phone, which increases the hardware complexity and production cost.

In view of this, the embodiment of the present application proposes a solution, which can reduce user operations and improve the convenience of unlocking compared to the button unlocking solution; and can solve the relay attack problem faced by the above-mentioned existing non-inductive unlocking solution, and the installation Weak antennas add to the problem of cost. The solution provided by the embodiment of the present application can be implemented based on the interaction between the terminal device side and the target device side.

In some embodiments, the technical means of at least detecting the motion state within the signal range is adopted, and in another part of the embodiments, the technical means of at least active inquiry within the signal range are adopted to solve the above problems.

The following is a preliminary introduction to the solution provided by the embodiment of this application in combination with two examples of application scenarios:

Exemplary application scenario one:

Referring to Figure 3, taking the car unlocking scene as an example, the user U1 holds the terminal device UE1 and arrives near the vehicle. The terminal device UE1 detects the wireless signal sent by the vehicle-mounted target device C1, and a secure connection is established between the terminal device UE1 and the target device C1. . Afterwards, as shown in the exemplary situation shown in Figure 3, the terminal device UE1 is placed in the user bag and is in a locked screen state. In this case, the terminal device UE1 at least detects whether its own device is in a motion state, and determines that it is in a motion state , then send an unlock message to the target device C1, and the target device C1 controls the electronic door lock to open, and the vehicle can emit a corresponding prompt sound, such as a beep or a voice prompt "Hello, the lock is unlocked", if it does not happen After the attack, the user is on the scene. After learning that the lock has been opened, the user can hold the door handle or press the door open button on the door handle to open the door, and unlock the door without feeling. At the same time, in order to further improve safety, The target device C1 returns a successful unlock message to the terminal device UE1. After receiving the successful unlock message, the terminal device UE1 will immediately prompt the user that the car lock has been unlocked. If there is no relay attack, the user can ignore the prompt at this time. , without any operation; if a relay attack occurs, the user can immediately know that the vehicle may be at risk of being stolen, and then immediately send a lock message through the terminal device UE1 to lock the door again to prevent the vehicle from being stolen.

Among them, the terminal device carried by the user is in a state of motion, which will greatly increase the difficulty of relay attacks. When the terminal device moves, its signal strength changes at any time. In this case, it is difficult to implement relay attacks; In practical applications, when the user needs to unlock the vehicle, he will approach the vehicle with a high probability of being in a motion state. Therefore, whether the user is currently in motion can be used as a direct and effective necessary reference factor to distinguish whether the user needs to unlock. To a certain extent, it can Avoid relay attacks.

Referring to Fig. 4, in another part of the embodiment, when the user U1 holds the terminal device UE1 and arrives near the vehicle, after the terminal device UE1 establishes a secure connection with the vehicle target device C1, as shown in the exemplary situation in Fig. 4, this At this time, if the terminal device UE1 is in the unlocked state, that is, the user is using the terminal device UE1, in this case, based on UI (User Interface)/UX (User Experience) interaction, the user can actively ask the user whether to unlock the car lock. For example, when the terminal device UE1 detects that it has entered the signal range of the vehicle-mounted target device C1, it will automatically pop up a dialog box asking whether to unlock the car lock, and display the button for sending the unlock message and the button for sending the lock message, without the need for the user to find the operation interface by himself. , directly click the corresponding unlock or lock button on the pop-up dialog box to realize the switch control of the car lock. In the prior art, the button unlocking method of unlocking through a mobile phone requires the user to find and open the corresponding application (application, APP) after arriving near the vehicle, or find the unlocking program from the running program, enter the control interface, and click to unlock. Press the button to realize unlocking. The active inquiry method provided by the embodiment of the present application takes the user entering the short-distance range of the vehicle as a triggering opportunity to actively ask the user whether to unlock, reducing user operations.

It should be noted that this active inquiry method is not completely insensitive to the user, but the operation convenience is significantly improved compared with the button unlocking in the prior art, and this active inquiry method, If the user does not send an unlock message, the car lock will not be unlocked, which can completely avoid the problem of relay attacks, and the security is higher.

In the embodiment of the present application, the terminal device may be various mobile terminal products that support short-distance wireless communication carried by the user, for example, it may be a mobile phone, a tablet computer, a personal computer (personal computer, PC), a personal digital assistant (personal digital assistant), etc. assistant, PDA), smart watches, netbooks, wearable electronic devices, augmented reality (augmented reality, AR) devices, virtual reality (virtual reality, VR) devices, robots (portable), smart toys, etc., can also be car keys .

The target device is the device used for wireless communication with the terminal device in the vehicle pre-opened by the user. The target device can be an independent vehicle-mounted device, or one or more components integrated into the vehicle-mounted device. The vehicle can at least support proximity Any in-vehicle device, module or component that communicates wirelessly and can directly or indirectly control the lock can be used as a target device. For example, the target device may be one or more of the following vehicle-mounted devices or modules, or one or more components integrated in the following vehicle-mounted devices or modules: vehicle gateway (gateway, GW) module, telematics control unit (Telematics Control Unit, TCU), car box (telematics BOX, T-BOX), mobile data center (mobile data center, MDC), human-machine interaction (human–machine interaction, HMI) module, electronic control unit (electronic control unit, ECU) ), cockpit domain controller (CDC), or vehicle domain controller (vehicle domain controller, VDC).

Among them, the vehicle gateway GW module is the core component in the electronic and electrical architecture of the vehicle. As the data exchange hub of the vehicle network, it can control the area network (controller area network, CAN), the local interconnect Multimedia data transmission (media oriented system transport, MOST), FlexRay and other network data are routed in different networks. The mobile data center MDC is used as the intelligent on-board computing platform of the car; the human-computer interaction HMI module can be used as the infotainment system of the car; the telematics control unit TCU can be used to communicate with the car's exterior, background system and smart phone, application network equipment, etc. Communication; the car box T-BOX can be used to communicate with the outside of the car, the background system, smart phones, APP network devices, etc.; the electronic control unit ECU is a microcomputer controller dedicated to the car; the cockpit domain controller CDC is used to control the relevant content of the cockpit domain; The vehicle domain controller VDC is used to control the content related to the vehicle domain.

The target electronic lock is the car lock of the vehicle that the user pre-opens. The car lock is not limited to the door lock, but also includes window control components, trunk lock control components, and control units for electrical equipment such as speakers in the car and air conditioners. The target electronic lock may include a physical mechanical lock and/or an electrical switch controlled by a control signal.

The target device and the target electronic lock can be two independent devices or components, or they can be deployed in different devices or modules. The target device and the target electronic lock can also be integrated into the same device. For example, the target device can be used as a car lock accessories for use only for communication tasks related to the lock.

The process of the unlocking method provided in the embodiment of the present application is described in detail below:

In some embodiments, when the user enters the signal range of the vehicle and is in motion, the unlocking is triggered and an unlocking notification is sent to the user. The subject of execution of the method may be a terminal device, including the following process: when it is determined that the target device has entered the signal range of the target signal, it is detected whether the terminal device is in a predetermined motion state, and if it is determined to be in a motion state, then an unlocking signal is issued to the target device. message, and trigger a first event, which is an interaction event used to prompt the user that the target electronic lock corresponding to the target device has been unlocked.

Among them, determining the signal range of the target signal sent by the target device includes two layers of meaning: one layer of meaning is that the terminal device is currently within the signal range of the target device; the other layer of meaning is the change from the lost signal state to the searchable signal state , instead of changing from the searched signal state to the lost signal state, that is, "entering" the signal range, not away from it. The premise of being able to determine the signal range of the target signal sent by the target device is that the signal sent by the target device can be searched at present, and the signal of the target device has not been found before. As a possible implementation, take 3 seconds (s) as a query cycle, record whether the terminal device has searched for the signal state of the target device every 3s, when it is determined that the signal of the target device has been found (that is, the signal state is found), Query whether it is in the state of losing signal in the previous one or two adjacent time periods, and wait for the next cycle, and check whether the record of the next cycle is in the state of finding the signal, if yes, then determine the signal range of the target signal sent by the target device . This implementation manner can avoid repeated triggering of unlocking when the user is continuously within the signal range of the vehicle.

It should be noted that the short-range wireless communication technology is used for communication between the terminal device and the target device, such as Bluetooth (bluetooth), wireless fidelity (Wireless Fidelity, Wi-Fi), near field communication (Near Field Communication, NFC). ), Zigbee protocol (Zigbee), ultra-wideband (Ultra Wide Band, UWB), radio frequency identification technology (Radio Frequency Identification, RFID), etc. at least one. Among them, in addition to NFC, several other communication methods can control the signal transmission distance by adjusting the power.

In a possible implementation manner, Bluetooth is used as the communication mode between the terminal device and the target device. When the terminal device determines to receive the beacon frame broadcast by the target device, it determines that it is currently within the signal range of the target device.

In a possible implementation manner, after the signal of the target device is found, the signal strength is further detected. For some short-range wireless communication technologies, the communication distance can reach ten meters or even dozens of meters. When the terminal device enters the signal range of the target device, the actual distance between the terminal device and the vehicle may be more than ten meters. Therefore, it is necessary to further obtain signal strength information, that is, to obtain the value of Received Signal Strength Indication (RSSI), and the unit is decibel relative to one milliwatt (dBm). When the signal strength exceeds the specified threshold, the subsequent steps are performed. For example, after the target signal is found, the signal strength is detected immediately to determine whether the signal strength reaches the specified threshold, and then detects whether it is in a motion state, or, after detecting that the terminal device is in a motion state, then determine the current signal strength, and the signal strength exceeds the specified threshold. threshold, the unlock message will be sent, otherwise the unlock message will not be triggered until the signal strength exceeds the specified threshold. There is no clear sequence limitation on the time sequence of motion state detection and signal strength determination.

It should be noted that when the effective communication distance of the communication mode between the terminal device and the vehicle is within several meters, the step of signal strength detection may not be performed, for example, when the effective communication distance is less than 10 meters or less than 5 meters. When the target device in the vehicle is installed with a weak antenna (ultra-short-range antenna) or the effective signal range is only a few meters near the vehicle by adjusting the antenna transmission power of the target device on the side of the vehicle, then there is no need to perform signal strength determination A step of. When the effective communication distance of the communication method between the terminal device and the vehicle exceeds 10 meters, and due to considerations of cost, solution compatibility and implementation difficulty, it is impossible to reduce the power of the antenna on the target device or mobile phone, then After entering the signal range, the signal strength should be further determined to ensure that the distance between the terminal device held by the user and the vehicle is within the distance threshold. The distance threshold can be 5 meters, 6 meters, 10 meters, etc.

The specified threshold of signal strength is related to the distance threshold. When the distance threshold is determined, the signal strength around the vehicle at the distance threshold can be sampled. The average value of multiple signal strength samples can be used as the specified threshold of signal strength.

The reason why a weak antenna needs to be installed in the prior art is that the effective communication distance between the control vehicle and the mobile phone is relatively short, for example, within a range of about 1.5 meters. In the solution provided by the embodiment of the present application, based on the above-mentioned trigger mechanism, signal strength is further used as the trigger unlocking condition, which can solve the technical problem of needing to install a weak antenna. By setting different signal strength thresholds, when the signal strength exceeds the threshold, trigger again. Unlocking can effectively control the distance range for triggering unlocking without installing weak antennas, which saves various costs for installing weak antennas.

It should be noted that the detection of whether the person is in a motion state can be identified by collecting motion data through a sensor. That is, the predetermined motion state is determined according to the data collected by the motion sensor of the terminal device. The motion sensor includes one or more of a gyroscope, a gravity sensor, an acceleration sensor, a magnetic sensor, a vibration sensor, a linear velocity sensor, and an angular velocity sensor. The data collected by the sensor can be motion parameters such as motion direction, tilt angle, space attitude, and travel speed. Collecting motion data is a function supported by various terminal devices, such as mobile terminal devices such as smart phones and smart watches. In the embodiment of the present application, the existing detection function can be used to identify the motion state by using the detected motion data.

For example, as a possible implementation, the terminal device can have a built-in gyroscope, a gravity sensor, and an acceleration sensor, and the gyroscope can sense the direction of the user's movement; the gravity sensor can measure the acceleration caused by gravity to calculate the relative The inclination angle of the horizontal plane; the acceleration information of the terminal device is collected through the acceleration sensor. It can be combined with the movement direction, tilt angle and acceleration information to comprehensively judge whether the user is in a movement state.

In a possible implementation, the predetermined exercise state may include one or more of walking, fast walking, slow walking, running, jogging, fast running, and jumping. When the user drives the terminal device to be in any of the above states , the terminal device is considered to be in a predetermined motion state. Specifically, according to the data sensed by the above-mentioned sensors, the number of steps or the frequency of the user's movement can be determined, and then it can be determined whether the user is in any of states such as fast walking, slow walking, fast running, and jogging. States such as walking, fast walking, slow walking, running, jogging, fast running, jumping, etc. can be obtained through statistics of multiple sample data.

Specifically, detecting whether it is in motion can be achieved in the following ways:

Method 1: The collected exercise data is compared with a predetermined parameter threshold or a predetermined condition, and if the threshold is exceeded or the predetermined condition is met, the terminal device carried by the user is considered to be in a state of exercise. For example, the number of steps of the user is determined through the parameters collected by the above sensors, and when the number of steps of the user continues to increase within a predetermined period of time, it is determined that the user and the terminal device they carry are in a state of exercise. For example, take 5s as a detection period, and detect whether the user's step count increases every 5s. If the user's step count increases during multiple consecutive detection periods, the user is considered to be in a state of exercise.

Method 2: Based on big data, obtain the state parameters of the user before opening the car door, obtain multiple samples, and perform statistical analysis on them, such as using a cluster analysis algorithm to obtain reference features corresponding to the general state characteristics of the user before opening the car door Vector, when judging whether the current target user is in a state of motion, the collected motion parameters can be converted into a target feature vector, the target feature vector is compared with a pre-acquired reference feature vector, and based on the comparison result, it is determined whether the current target user is in motion. Wherein, the process of obtaining the reference feature vector is implemented on the server on the network side, and the reference feature vector can be pre-stored in the terminal device as a program parameter.

Way 3: Another possible way to detect whether they are in motion is to obtain the state parameters of multiple users before opening the car door as training data, use whether they are in motion as a label, train the neural network model, and then, in the actual In the application stage, the feature vector corresponding to the collected motion parameters of the target user is used as input, and the recognition result of whether it is in a motion state is output through the pre-trained neural network model. The implementation of the third method usually requires the interaction between the terminal device and the server on the network side. In most cases, the trained neural network model is deployed on the server on the network side.

In a possible implementation, after the first event is used to remind the user that the car lock has been unlocked, the second event is also used to ask the user whether the car lock has been unlocked by mistake, and to receive a lock lock instruction from the user. In practical applications, when a relay attack is received, the unlocking behavior is obviously not what the user expected, and the car lock needs to be closed as soon as possible; After the user's car lock is unlocked, an interactive entry for the user to quickly lock the car door should be provided.

In order to further understand the unlocking method provided by the embodiment of the present application, several embodiments are listed below.

Firstly, an example is given that applies to the scene where the terminal device is in the locked screen state before unlocking. This embodiment triggers non-inductive unlocking according to whether the mobile phone/car key and other terminal devices are in the locked screen state and whether they are moving. After unlocking, add the mobile phone/key, etc. The prompt on the side of the terminal device allows the user to know in a short time that the car lock has been opened by mistake or due to an attack, and then immediately issue a lock command or go to the scene to manually lock the door to eliminate the risk. Specifically, referring to Fig. 5, this embodiment may include the following processes:

Step 501, the terminal device discovers the first target signal sent by the target device;

For example, the terminal device searches for the beacon frame sent by the target device (that is, the vehicle-mounted target device shown in Figure 5), and the signal is lost in the previous adjacent query cycle, and the next query cycle is also a discovery signal state, it is determined that the target device is found, and the target device enters the target signal range of the target device.

It should be noted that the terminal device can regard the signal sent by the target device as the target signal, and the target device can also regard the signal sent by the terminal device as the target signal. For the convenience of description, the signal sent by the terminal device is defined as the first target signal , defining the signal sent by the target device as the second target signal.

Step 503, the terminal device detects that it is in a screen-locked state;

Step 505, the terminal device detects that it is in motion;

Step 507, establishing a secure connection between the terminal device and the target device;

A secure connection is established, that is, securely authenticated for communication. Different communication technologies correspond to different security authentication methods. For example, in a possible implementation, when the terminal device communicates with the target device through Bluetooth, it can be based on secure simple pairing SSP (Secure Simple Pairing), Secure Connections , LE Secure Connections and other encryption authentication mechanisms for security authentication; another example, when performing Wi-Fi communication between a terminal device and a target device, Wi-Fi Protected Access-PreShared Key (Wi-Fi Protected Access-PreShared Key) can be used Key, WPA-PSK)/WPA2-PSK authentication mechanism.

Step 509, the terminal device sends an unlock message to the target device;

Step 511, the target device sends an unlock success message to the terminal device after unlocking;

Step 513, after the terminal device receives the unlocking success message, it prompts the user that the car lock has been unlocked;

In a possible implementation manner, after the terminal device receives the unlocking success message sent by the target device, the terminal device will trigger the first event to remind the user that the target electronic lock corresponding to the target device has been unlocked. The prompt method can be At least one of sound, vibration, push text message, and light up the screen, wherein the sound includes voice, ringtone, buzzer, and other various types of prompt sounds. The first event can specifically be voice broadcast, ringing, sending Beep, vibration, push message, light up the screen, or a combination of two or more. If the terminal device is in the lock screen state, you can choose vibration or sound prompts, such as voice broadcast "Your vehicle is unlocked" after it has been unlocked, or combine different prompt methods, such as voice broadcast while vibrating, or Ring the bell while vibrating to remind the user that the car lock is unlocked, or display a push message on the lock screen interface. If the terminal device is in the screen-off state, it may display a pushed push message, or other ways of pushing a text message to prompt the user. In this embodiment, it is a small probability event that the terminal device changes from the locked screen state in step 502 to the unlocked screen state, so when step 513 is executed, a prompt manner corresponding to the locked screen state may be used.

Step 515, the terminal device detects that the user unlocks the device.

In this embodiment, after the user hears the sound prompt of the mobile phone or feels the vibration prompt, if the user does not unlock the lock at his own will, he will actively open the mobile phone to check. If the user chooses to ignore the prompt instead of unlocking the phone, it is most likely because the door is unlocked at the user's own will and has not been attacked by a relay.

Step 517, ask the user whether to open the car lock by mistake, and whether to close the car lock.

This step 517 can be realized by triggering a second event, and the second event is used to inquire whether the user opened it by mistake, and to receive a lock-off instruction from the user. As an implementable mode, after the user unlocks the mobile phone, a dialog box or an option prompt box asking the user whether to open the car lock by mistake will pop up, and at least a lock button for confirming that it is accidentally opened is set in the dialog box or the option prompt box , to receive the lock command from the user.

For example, referring to FIG. 6, in the locked screen state, in step 513, the user is reminded that the car lock has been unlocked by means of vibration combined with lighting the screen, and an example interface of the terminal device when the first event is triggered is shown in interface I1 in the figure. At this time, the screen is turned on when the screen is locked, and a notification message "Your car lock has been unlocked, click to view details" pops up. screen, at this time the terminal device has detected the user’s screen unlock command, and after unlocking the screen, an option prompt box as shown in interface I2 will pop up “Your car lock has been unlocked, did you open it by mistake?” and set the option for closing the lock "Open by mistake, close the lock" and "Ignore" options, the user can send a lock command by clicking the "open by mistake, close the lock" option to control the lock to close again. When the user selects "Ignore" or does not perform any operation, the option prompt box will disappear automatically.

Optionally, step 506 may be added between step 505 and step 507, the terminal device detects the signal strength of the received target signal, and when it is determined that the signal strength exceeds a specified threshold, then step 507 is executed; or, between step 501 and step Step 503 increases the step of detecting signal strength; or, increases the step of detecting signal strength between step 503 and step 505, so that multiple other embodiments can be obtained based on the embodiment shown in FIG. 5 .

Optionally, step 515 may not be included in the embodiment shown in FIG. 5 , that is, after the terminal device prompts the user that the car lock has been unlocked, the user does not need to unlock the terminal device, and can directly confirm on the lock screen interface of the terminal device. Whether it was opened by mistake. That is to say, the interface I2 in Figure 6 can also be an interface where the terminal device is in the lock screen state, and the user can send a lock command by clicking on the option "open by mistake, close the lock" to control the lock to close again; the user selects " Ignore" or do not perform any operation, the option prompt box will disappear automatically.

Another example is applicable to the scenario where the terminal device is in the unlocked state before unlocking. Referring to FIG. 7, this embodiment may include the following process:

Step 701, the terminal device discovers the first target signal sent by the target device;

Step 702, the terminal device detects that it is in a screen-unlocking state;

Step 703, the terminal device detects that it is in motion;

Step 704, the terminal device detects the signal strength of the received first target signal;

Step 705, establishing a secure connection between the terminal device and the target device;

Step 706, the terminal device sends an unlock message to the target device;

Step 707, the target device sends an unlock success message to the terminal device after unlocking;

Step 708: After receiving the successful unlocking message, the terminal device pushes a push message indicating that the car lock has been unlocked, and provides a shortcut to unlock the car. This step 708 can be implemented by triggering a third event. The third event can be used to provide a shortcut to receive a lock lock command issued by the user. In this embodiment, the third event is used to push a push message that the car lock has been unlocked, and provide a shortcut to lock the lock.

This embodiment realizes the non-inductive unlocking of the terminal device when the screen is unlocked, and is applicable to the scene where the user walks to the vehicle while operating the terminal device such as a mobile phone, for example, the user is making a voice or video call while walking to the vehicle, or is editing text messages and more. It should be noted that, unlike the embodiment corresponding to FIG. 5 , in the applicable scenario of the embodiment shown in FIG. 7 , the user still keeps the screen of the mobile phone unlocked during the process of walking towards the vehicle. The transaction of interest is being processed. Therefore, in this embodiment, the focus is on reducing the interference to the user. Therefore, in step 708, after the unlock is successful, a third event can be triggered to remind you in the form of a text message such as a push message The user has opened the lock, and does not use ringing or vibration reminders that may interfere with the user, and to ensure safety, provide a shortcut for the user to close the car lock. For example, the shortcut can provide a floating window , set a lock button in the floating window, the user can click the lock button without affecting the running of the current main interface program. Optionally, in the embodiment shown in FIG. 7 , the terminal device may also ring or vibrate, so as to remind the user that the car lock is unlocked in a way that is less likely to be ignored by the user.

For example, referring to Fig. 8(a) and Fig. 8(b), Fig. 8(a) exemplarily shows that when the terminal device is in the screen-off state, when the current interface is waiting to answer the video chat interface, the push message that the car lock is successfully unlocked is pushed "**** Prompt: The car lock is successfully unlocked!", Figure 8(b) exemplarily shows the push message "*** that the car lock is successfully opened when the current interface is a chat interface when the terminal device is in the unlocked state" *Prompt: The car lock has been unlocked successfully!", where **** can be the name of the APP installed on the terminal device to implement the unlocking method provided by the embodiment of this application. Optionally, the user can view the push message by sliding down the notification bar. FIG. 8( a ) and FIG. 8( b ) are only examples, and the triggering of the third event may also be performed in multiple other interface states, which are not listed in this embodiment of the present application. And in the third event, the successful unlocking message is not limited to being pushed in the form of a push message, for example, the user may also be notified in the form of a floating box or the like.

The third event is also used to provide a shortcut for closing the lock, which can be a corresponding link button in the push message, for example, the "click to quickly close the lock" shown in Figure 8 (a) and Figure 8 (b) ".

The above-mentioned Figure 5 and Figure 7 show the steps of non-inductive unlocking, as shown in Figure 9, after performing the non-inductive unlocking in step 900, the following steps may also be included:

Step 901, the user confirms that it was opened by mistake;

When the terminal device receives an instruction to confirm the wrong opening or a lock lock message from the user, it is deemed that the user confirms the wrong opening.

Step 902, the terminal device sends a lock message to the target device (i.e. the vehicle-mounted target device shown in Figure 9);

Step 903, the terminal device discovers the first target signal again;

Step 904, the terminal device starts timing, and no longer unlocks the lock involuntarily within the first timing period;

Step 905, the terminal device loses the first target signal;

If the terminal device cannot search for the signal sent by the target device, it will be deemed as having lost the first target signal. For example, the beacon frame broadcast by the target device cannot be received.

Step 906, the terminal device rediscovers the first target signal;

Step 907, the terminal device performs non-sensing unlocking again.

Specifically, in a possible implementation manner, referring to FIG. 10 , the function of non-inductive unlocking is no longer performed in the first timing period after the non-inductive unlocking, which can be realized through the process shown in FIG. 10 :

Step 1001, the user confirms that it was opened by mistake;

Step 1002, judging whether the first target signal is lost? If yes, the user is outside the signal range of the vehicle at this time, return to step 1000 to continue to wait for the user to carry the terminal device and return to the vicinity of the vehicle again (that is, the terminal device can find the first target signal) to perform non-inductive unlocking; if not, enter Step 1003;

Step 1003, start the timer for timing. The timing duration is the first timing period.

Step 1004, judging whether the first timing period has been reached? Yes, the timing is over, and return to step 1000; no, it is still in the first timing cycle at this time, and enter step 1005;

Step 1005, interrupt the non-inductive unlocking process. In the first timing period, even if the first target signal is found again, the non-inductive unlocking is not performed. For example, a feasible control manner may be to send an interrupt signal to a corresponding process for implementing the non-inductive unlocking to interrupt the process when it is determined that the timing is not over.

The embodiment shown in FIG. 10 can solve the problem that the terminal device repeatedly reminds whether to unlock and interfere with the user in the following scenarios. Specifically, the scenario is that the user moves around the car, causing the terminal device to repeatedly leave the signal range of the vehicle target device and repeatedly enter the signal range of the vehicle target device. At this time, if the embodiment shown in FIG. 9 is implemented, each time the vehicle-mounted target device rediscovers the first target signal, the terminal device will unlock again without any sense, causing the car lock to be turned on and off repeatedly, and the terminal device to repeatedly ask the user whether to unlock it. User interference. Now if implement the embodiment shown in Figure 10, then can solve above-mentioned problem, start timer by step 1003, before timing ends, all can execute step 1005 to interrupt the non-inductive unlocking that rediscovers that the first target signal causes, thereby can reduce Interference to users in this scenario.

Figure 9 or Figure 10 shows a feasible implementation after non-inductive unlocking. It should be noted that step 900 shown in Figure 9 or step 1000 shown in Figure 10 may include detecting the first target signal from the terminal device until The process of unlocking the vehicle lock in any embodiment, for example, step 900 or 1000 may specifically include steps 501 to 517 shown in FIG. 5 , or include steps 701 to 708 shown in FIG. 7 . Therefore, the flow shown in FIG. 9 or FIG. 10 can be combined with the flow shown in FIG. 5 or FIG. 7 to obtain other multiple embodiments, for example, steps 501 to 517 shown in FIG. One embodiment can be obtained by combining steps 1001 to 1005 shown in FIG. 7 , and another embodiment can be obtained by combining steps 701 to 708 shown in FIG. 7 with steps 1001 to 1005 shown in FIG. 10 .

The above embodiments adopt the technical means of at least performing motion detection after entering the range of the first target signal. In another part of the embodiments, after detecting that the user enters the signal range of the vehicle, the user is actively asked whether to unlock the car lock. Examples based on active inquiry are listed below.

To cite an embodiment applicable to the scene where the terminal device is in the unlocked state before unlocking, as shown in FIG. 11 , this embodiment may include the following process:

Step 1101, the terminal device discovers the first target signal sent by the target device;

Step 1103, the terminal device detects that it is in motion;

Step 1105, the terminal device asks the user whether to unlock?

Wherein, inquiring whether the user unlocks is realized by triggering a fourth event, and the fourth event is used to inquire whether the user unlocks the target electronic lock corresponding to the target device, and waits to receive an unlock instruction issued by the user.

Step 1107, the terminal device receives an unlocking instruction sent by the user to confirm the unlocking;

Step 1109, the terminal device establishes a secure connection with the target device;

Step 1111, the terminal device generates an unlock message based on the user's unlock command, and sends it to the target device;

Step 1113, the terminal device receives the unlock success message sent by the target device;

Step 1115, the terminal device prompts the user that the unlocking is successful. This step 1115 can be realized by triggering a fifth event.

Optionally, between step 1103 and step 1105, step 1104 may also be added. Step 1104 may be: when the terminal device detects that it is in the screen unlocking state, then execute step 1105; or step 1104 may be: the terminal device receives When the signal strength of the first target signal exceeds the specified threshold, execute step 1105; or, step 1104 may be: when the terminal device detects that the screen is in an off-screen state and the received signal strength of the first target signal exceeds the specified threshold, Then execute step 1105; or, step 1104 may be: when the terminal device detects that it is in a screen-off state or the signal strength of the received first target signal exceeds a specified threshold, then execute step 1105. In this way, based on the flow shown in FIG. 11 , multiple embodiments can be obtained.

For example, referring to FIG. 12 , for example, the user is watching a video, and the interface status of the terminal device is interface I3 as shown in FIG. When it is moving, the fourth event is triggered, and the option prompt box shown in interface I4 in Figure 12 pops up "*** has detected that your vehicle is nearby, do you want to unlock the car?" and at least set the "unlock" button. After the user clicks the "unlock" button, the terminal device sends an unlock message to the target device, making it control the target electronic lock from locked state to unlocked state. After receiving the notification of successful unlocking returned by the target device, push a push message on the current interface or pop up a floating box to display "The car lock is successfully unlocked". For an example of the corresponding interface, refer to interface I5 in Figure 13.

It should be noted that the embodiment shown in FIG. 11 is not limited to the scenario where the terminal device is in the unlocked state. When the terminal device is in the locked screen state, the current state of the terminal device can also be detected, such as the signal state, When the motion state meets the unlocking conditions, a dialog box or an option prompt box will pop up actively, allowing the user to choose whether to unlock. Among them, different from the implementation mode in the unlocked state, in the solution implemented in the locked screen state, the way of triggering the fourth event, that is, actively asking the user whether to unlock the lock, should be more prominent, so that the user can notice, for example, It is a reminder method combining vibration, ringing and lighting the screen. In this way, with reference to the process shown in FIG. 11 and related text descriptions, multiple other embodiments in the locked screen state can be obtained, which will not be introduced one by one here.

It should be noted that the feasible way shown in FIG. 9 or 10 after the non-sensing unlocking process can also be combined with the non-sensing unlocking process in FIG. 11 or 12 to obtain multiple other embodiments.

In another practicable way, after sending the unlock message to the target device, the following operations can also be performed: obtain the switch state information of the switch device corresponding to the target electronic lock, and determine the switch state information within the second timing period based on the switch state information. When the device is not opened, a lock message is sent to the target device. The lock message is used to notify the target device to control the target electronic lock from an unlocked state to a locked state. This implementation method is mainly used in application scenarios where the user does not actually open the car door or the house door after the target electronic lock such as the car lock or door lock is opened. Wherein, the switch device may be a car door, a house door, a trunk lid of a car, etc., and the target electronic lock may be a house door, a car door, an electronic lock on a trunk, etc. In practical application scenarios, it is possible that after the electronic lock such as the car lock or door lock is opened, the user does not pull the handle of the car door or the door, and the door or the door is still closed. In this case, if the car door or house door is not opened, it means that the user did not actually need to open the car door at this time, it may be opened by mistake, or the user may have other things temporarily and left after approaching the vehicle. If the unlocking or door lock etc. continue to be kept open, there will be a safety risk. Therefore, when it is detected that the switch device corresponding to the target electronic lock is not opened within a certain time period (second timing period), it will be automatically locked. For example, the second timing period may be 3-5 minutes. This implementation manner can be combined with the unlocking process in any embodiment to obtain multiple other embodiments.

The above-mentioned embodiments are all described from the perspective of the terminal device as the execution subject. In practical applications, the above-mentioned unlocking method may also be implemented based on a target device (eg, a vehicle-mounted target device). In yet another part of the embodiments, the process of the unlocking method implemented based on the target device includes: after determining that the terminal device enters the signal range of the first target signal sent by the target device, acquiring the motion state information of the terminal device; determining the terminal device based on the motion state information When the device is in a moving state, control the target electronic lock corresponding to the target device from the locked state to the unlocked state; send the first instruction to the terminal device so that the terminal device triggers the first event, where the first event is used to remind the user of the target Electronic lock is on.

Or, in yet another part of the embodiments, the process of the unlocking method implemented based on the target device may include: after determining that the terminal device has entered the signal range of the first target signal sent by the target device and the terminal device is in a predetermined motion state, sending a message to the terminal device Sending a fourth instruction, so that the terminal device triggers a fourth event, the fourth event is used to ask the user whether to open the target electronic lock corresponding to the target device, and wait for the receiving user to issue an unlocking instruction; after determining that the unlocking message sent by the terminal device is received, Control the target electronic lock corresponding to the target device from the locked state to the unlocked state; the unlock message is generated after the terminal device determines to receive the unlock command.

Several embodiments of the unlocking method based on the target device are listed below.

Referring to Figure 14, taking the car unlocking scene as an example, the unlocking method performs automatic unlocking when the terminal device enters the signal range and is in motion. The specific process is as follows:

Step 1401, the target device detects that the terminal device is within the signal range;

Step 1402, the target device establishes a secure connection with the terminal device;

Step 1403, the target device performs at least one of detecting the signal strength of the second target signal, obtaining the screen state information of the terminal device, and obtaining the motion state information of the terminal device; at least one item includes any one or any two or more of them. combination. Among them, the screen state information indicates whether the screen is locked or unlocked, the motion state information indicates whether the terminal device is in a predetermined motion state, and the signal strength of the second target signal, that is, the signal strength that the target device can receive from the terminal device. signal strength.

Step 1404, the target device determines that the terminal device meets the unlocking conditions;

It should be noted that the target device can determine whether the terminal device meets the unlocking conditions according to at least one of the signal strength, screen status information, and motion status information obtained in step 1403 above. The unlocking conditions include at least: being within the signal range of the target device , in a predetermined state of motion. In other embodiments, the unlocking condition may further include the following conditions: at least one of a lock screen state and a signal strength exceeding a specified threshold.

Step 1405, sending an unlock control signal to the target electronic lock;

Step 1406, after detecting that the target electronic lock has been unlocked, send a first instruction to the terminal device. The first instruction is used to trigger a first event to notify the user that the car lock has been unlocked.

Referring to FIG. 15 , in another embodiment of the unlocking method based on the target setting, after detecting that the terminal device enters the signal range, the user is actively asked whether the user needs to unlock, which may specifically include the following process:

Step 1501, the target device detects that the terminal device is within the signal range;

Step 1502, the target device establishes a secure connection with the terminal device;

Step 1503, the target device performs at least one of detecting the signal strength of the second target signal, obtaining the screen state information of the terminal device, and obtaining the motion state information of the terminal device;

Step 1504, the target device determines that the terminal device meets the unlocking conditions. In this embodiment, the unlocking conditions at least include: the terminal device is located within the signal range of the target device; in other embodiments, the unlocking conditions may also include the following conditions: being in a predetermined motion state, signal strength exceeding a specified threshold, screen unlocking state at least one of the

Step 1505, send a fourth instruction to the target electronic lock; the fourth instruction is used to notify the terminal device to trigger a fourth event.

Step 1506, receiving an unlock message. The unlocking message is generated by the terminal device after it determines to receive the unlocking instruction from the user.

Step 1507, sending an unlock control signal to the target electronic lock.

Step 1508, after detecting that the target electronic lock has been unlocked, send a fifth instruction to the terminal device to trigger the terminal device to execute a fifth event to notify the user of successful unlocking.

After executing the unlock process based on the target device, the following operations can be performed based on the target device in several ways:

Method 1: After confirming that the lock message sent by the terminal device is received, control the target electronic lock corresponding to the target device from the unlocked state to the locked state. After that, if it is detected that the terminal device is within the signal range, trigger the first timing cycle. Timing, within the first timing period, the unlocking message is shielded, and the electronic lock of the control target is always kept in the locked state.

Method 2: After receiving the lock message sent by the terminal device, after detecting that the terminal device is out of the signal range, and then detecting that the terminal device enters the signal range and the terminal device is in motion, control the target device corresponding to the target device. The electronic lock changes from the locked state to the unlocked state.

Mode 3: Detect the switch state information of the switch device corresponding to the target electronic lock, and control the target electronic lock from the unlocked state to the locked state when it is determined that the switch device is not opened within the second timing period based on the switch state information.

The above three manners can be combined, and can be combined with any unlocking process based on the execution of the target device in the above embodiments to obtain multiple embodiments.
