[0021] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0022] It should be noted that the terms used herein are for describing specific embodiments only and are not intended to be limiting of exemplary embodiments according to the present invention.

[0023] In the absence of conflict, the embodiments of the present invention and the features of the embodiments may be combined with each other.

[0024] like Figure 1 As shown, the present application discloses a method for unlocking a shared rental vehicle, wherein the shared rental vehicle includes a smart lock module, and the smart lock module establishes a communication connection with a background server, and the method includes:

[0025] After receiving the unlocking information sent by the user's unlocking device, the smart lock module determines whether the unlocking information is an unlocking instruction, and if so, sends the received unlocking information to the backend server;

[0026] The backend server verifies the unlocking information sent, and if the verification is successful, sends an unlocking instruction to the smart lock module to unlock the shared rental vehicle; wherein the backend server stores the barcode and unlocking key of the unlocking device.

[0027] In some embodiments, the unlocking device and the smart lock module are both provided with a Bluetooth module, and the Bluetooth module is communicatively connected with the background server; the method further includes:

[0028] According to the distance between the Bluetooth module in the unlocking device and the location of the backend server, as well as the distance between the Bluetooth module in the smart lock module and the location of the backend server, it is determined whether the shared rental vehicle is in a safe unlocking environment. If the shared rental vehicle is in a safe unlocking environment and the unlocking information verification is successful, an unlocking instruction is sent to the smart lock module to unlock the shared rental vehicle.

[0029] In some embodiments, the distance between the Bluetooth module in the unlocking device and the location of the backend server, and the distance between the Bluetooth module in the smart lock module and the location of the backend server are obtained according to the signal indication strength of the Bluetooth module received by the backend server, specifically:

[0030] Get the absolute value of the average value of the Bluetooth module signal strength indicator;

[0031] According to the absolute value, the three-point positioning principle is used to respectively determine the distance between the Bluetooth module in the unlocking device and the location of the background server, and the distance between the Bluetooth module in the smart lock module and the location of the background server.

[0032] In some embodiments, whether the shared rental vehicle is in a safe unlocking environment is determined based on the distance between the Bluetooth module in the unlocking device and the location of the backend server, and the distance between the Bluetooth module in the smart lock module and the location of the backend server, specifically:

[0033] When the absolute value of the difference between the distance between the Bluetooth module in the unlocking device and the location of the backend server and the distance between the Bluetooth module in the smart lock module and the location of the backend server is less than the first set distance, the shared rental vehicle is in a safe unlocking environment.

[0034] In some embodiments, when there are multiple distances between the Bluetooth modules in the smart lock modules and the backend server location, and the absolute value of the difference between the distances between the Bluetooth module in the unlocking device and the backend server location is less than a first set value, the shared rental vehicle corresponding to the unlocking device with the smallest absolute value of the difference will be unlocked, and the voice unlocking broadcast will be enabled for the unlocked shared rental vehicle.

[0035] In some embodiments, an information transmission channel is established between the built-in Bluetooth module of the smart lock module and the external Bluetooth module arranged on the background server; the smart lock module receives the unlocking instruction sent by the terminal background server through the information transmission channel.

[0036] In some embodiments, the background server verifies the unlocking information sent, specifically: the background server determines whether the unlocking key, barcode and user ID contained in the unlocking information are consistent with the stored information.

[0037] In some embodiments, when the smart lock module detects a disconnection from the unlocking device, it sends a disconnection message to the background server. The background server receives the disconnection message and sends a locking instruction to the smart lock module to control the locking of the shared rental vehicle.

[0038] The present application discloses a method for unlocking a shared rental vehicle, wherein the shared rental vehicle includes a smart lock module, and the smart lock module establishes a communication connection with a background server. The method includes:

[0039] After receiving the unlocking information sent by the user's unlocking device, the smart lock module determines whether the unlocking information is an unlocking instruction, and if so, sends the received unlocking information to the backend server;

[0040] The backend server verifies the unlocking information sent, and if the verification is successful, sends an unlocking instruction to the smart lock module to unlock the shared rental vehicle; wherein the backend server stores the barcode and unlocking key of the unlocking device.

[0041] Among them, Figure 2 As shown, the smart lock module includes a second MCU, an unlocking module and a GPS; the unlocking device includes a first MCU and a lithium battery pack, and the lithium battery pack supplies power to the first MCU.

[0042] The Flash ROM inside the first MCU stores an unlocking key and a barcode of the smart lock module. The unlocking key corresponds to each user's ID and is stored in the background server together with the barcode. The unlocking key is unique and encrypted and burned into the Flash ROM of the first MCU at one time.

[0043] The first MCU communicates with the smart lock module of the shared rental car through a serial bus communication interface and sends an unlocking key and a barcode to the smart lock module. The serial bus communication interface uses a separately encrypted serial bus communication protocol, including a hardware identification ID and communication instructions.

[0044] After the smart lock module receives the barcode and unlock key, it uploads the barcode and unlock key to the background server; the smart lock module first determines whether the hardware identification ID matches, and then identifies the communication instruction. If it is an unlock instruction, the barcode and unlock key are sent to the background server.

[0045] The backend server verifies the barcode and the unlocking key. If the verification is successful, the user's ID is identified through the barcode and the unlocking key, and an unlocking instruction is sent to control the smart lock module to unlock. When the smart lock module is unlocked, the backend server starts timing and charging. When the smart lock module detects that the first MCU is disconnected from the smart lock, it sends an instruction to the backend server, and the backend server stops charging.

[0046] In this application, the distance between the Bluetooth module in the unlocking device and the location of the background server, and the distance between the Bluetooth module in the smart lock module and the location of the background server are obtained according to the signal indication strength of the Bluetooth module received by the background server, specifically:

[0047] Get the absolute value of the average value of the Bluetooth module signal strength indicator;

[0048] According to the absolute value, the three-point positioning principle is used to respectively determine the distance between the Bluetooth module in the unlocking device and the location of the background server, and the distance between the Bluetooth module in the smart lock module and the location of the background server.

[0049] Specifically, D=10^[(|RSSI|-A) / (10n)].

[0050] Where D is the distance between the background server and the Bluetooth module, |RSSI| is the absolute value of the average signal strength indicator value, A is the signal strength indicator value when the background server and the Bluetooth module are 1 meter apart, and n is the attenuation factor of the Bluetooth module.

[0051] In this application, whether the shared rental vehicle is in a safe unlocking environment is determined based on the distance between the Bluetooth module in the unlocking device and the location of the backend server, as well as the distance between the Bluetooth module in the smart lock module and the location of the backend server, specifically:

[0052] When the absolute value of the difference between the distance between the Bluetooth module in the unlocking device and the location of the backend server and the distance between the Bluetooth module in the smart lock module and the location of the backend server is less than the first set distance, the shared rental vehicle is in a safe unlocking environment.

[0053] When there are multiple distances between the Bluetooth modules in the smart lock modules and the location of the backend server, and the absolute value of the difference between the distances between the Bluetooth module in the unlocking device and the location of the backend server is less than a first set value, the shared rental vehicle corresponding to the unlocking device with the smallest absolute value of the difference will be unlocked, and the voice unlocking announcement will be started for the unlocked shared rental vehicle.

[0054] This application determines whether the shared rental vehicle is in a safe unlocking environment to avoid misunderstanding of locking the shared rental vehicle when the user's unlocking device is a certain distance away from the shared rental vehicle and the user has no intention of unlocking.

[0055] In this application, when the absolute value of the difference between the distance between the Bluetooth module in multiple smart lock modules and the location of the backend server and the distance between the Bluetooth module in the unlocking device and the location of the backend server is less than a first set value, the shared rental vehicle corresponding to the unlocking device with the smallest absolute value of the difference is unlocked and voice broadcast is performed to prevent one unlocking device from opening shared rental vehicles corresponding to multiple smart lock modules. In addition, through voice broadcast, when the distance between the user and multiple shared rental vehicles is not much different, the user can quickly determine the shared rental vehicle to be unlocked.

[0056] The purpose of this application is to provide an unlocking device for a shared rental vehicle, wherein the shared rental vehicle includes a smart lock module, and the smart lock module establishes a communication connection with a background server, including:

[0057] The smart lock module is used to determine whether the unlocking information sent by the user's unlocking device is an unlocking instruction after receiving the unlocking information, and if so, send the received unlocking information to the backend server;

[0058] The backend server is used to verify the unlocking information sent, and if the verification is successful, send an unlocking instruction to the smart lock module to unlock the shared rental vehicle; wherein the backend server stores the barcode and unlocking key of the unlocking device.

[0059] The present application provides a shared rental vehicle, which adopts the above-mentioned unlocking method of a shared rental vehicle.

[0063] The memory can be used to store software programs and modules, and the processor executes various functional applications and data processing by running the software programs and modules stored in the memory. The memory may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area may store data created according to the use of a shared rental vehicle (such as audio data, a phone book, etc.), etc. In addition, the memory may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices. Accordingly, the memory may also include a memory controller to provide the processor and the input unit with access to the memory.

[0064] The input unit can be used to receive input digital or character information, and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, the input unit may include a touch-sensitive surface and other input devices. The touch-sensitive surface, also known as a touch display or touchpad, can collect the user's touch operations on or near it (such as the user's operation on or near the touch-sensitive surface using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch direction, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into the touch point coordinates, and then sends it to the processor, and can receive and execute the command sent by the processor. In addition, the touch-sensitive surface can be implemented using multiple types such as resistive, capacitive, infrared and surface acoustic wave. In addition to the touch-sensitive surface, the input unit may also include other input devices. Specifically, other input devices may include, but are not limited to, one or more of a physical keyboard, function keys (such as a volume control key, a switch key, etc.), a trackball, a mouse, a joystick, and the like.

[0065] The display unit can be used to display information input by the user or information provided to the user and various graphical user interfaces of the shared rental vehicle, which can be composed of graphics, text, icons, videos and any combination thereof. The display unit may include a display panel. Optionally, the display panel may be configured in the form of LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), etc. Further, the touch-sensitive surface may cover the display panel. When the touch-sensitive surface detects a touch operation on or near it, it is transmitted to the processor to determine the type of touch event, and then the processor provides corresponding visual output on the display panel according to the type of touch event. The touch-sensitive surface and the display panel are implemented as two independent components to implement input and output functions, but in some embodiments, the touch-sensitive surface can be integrated with the display panel to implement input and output functions.

[0066] Shared rental vehicles may also include at least one sensor, such as light sensors, motion sensors and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel according to the brightness of the ambient light, and the proximity sensor may turn off the display panel and / or backlight when the shared rental vehicle is moved to the ear. As a type of motion sensor, the gravity acceleration sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometers, tapping), etc.; as for other sensors that can be configured for shared rental vehicles, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0067] The audio circuit, speaker, and microphone can provide an audio interface between the user and the shared rental vehicle. The audio circuit can transmit the electrical signal converted from the received audio data to the speaker, which is converted into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit and converted into audio data. The audio data is then processed by the output processor and sent to, for example, another shared rental vehicle through the RF circuit, or the audio data is output to a memory for further processing. The audio circuit may also include an earphone jack to provide communication between an external headset and the shared rental vehicle.

[0068] WiFi is a short-range wireless transmission technology. The shared rental vehicle can help users send and receive emails, browse web pages, and access streaming media through the WiFi module, which provides users with wireless broadband Internet access. Although the WiFi module is shown, it is understandable that it is not a necessary component of the shared rental vehicle and can be omitted as needed without changing the essence of the invention.

[0069] The processor is the control center of the shared rental vehicle. It uses various interfaces and lines to connect various parts of the entire mobile phone. By running or executing software programs and / or modules stored in the memory and calling data stored in the memory, it executes various functions of the shared rental vehicle and processes data, thereby monitoring the mobile phone as a whole. Optionally, the processor may include one or more processing cores; preferably, the processor may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, etc., and the modem processor mainly processes wireless communications.
