[0002] At present, shared vehicles (for example, shared bicycles) have become an increasingly popular means of travel. Usually, a hardware lock is installed on a shared vehicle. If a user (hereinafter, also referred to as a user) wants to use a shared vehicle, he needs to unlock the shared vehicle first. After the use of the shared vehicle is over, the user needs to park the shared vehicle in a designated area where shared vehicles can be parked. The shared vehicle can only be locked after it is parked in the designated area. In some cases, the user may park the shared vehicle in the designated area, but may still not be able to lock it. This will bring a poor car experience to the user. Therefore, it is worth paying attention to how to accurately determine whether the shared vehicle is parked in the designated area.

On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

Various embodiments are described throughout this article, and any type of embodiment may be included under any section / subsection. In addition, the embodiments described in any section / subsection may be combined in any manner with any other embodiments described in the same section / subsection and / or different sections / subsections.

[0024] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may be included below. The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below.

[0025] The embodiments of the present disclosure may involve user data, data acquisition and / or use, etc. These aspects are subject to the corresponding laws, regulations and relevant provisions. In the embodiments of the present disclosure, all data collection, acquisition, processing, processing, forwarding, use, etc. are carried out on the premise that the user knows and confirms. Accordingly, when implementing each embodiment of the present disclosure, the type, scope of use, usage scenario, etc. of the data or information that may be involved should be informed to the user and the user's authorization should be obtained in an appropriate manner in accordance with the relevant laws and regulations. The specific notification and / or authorization method can vary according to the actual situation and application scenario, and the scope of the present disclosure is not limited in this respect.

[0026] The solutions described in this specification and in the examples, if they involve the processing of personal information, will be processed on the premise of having a legal basis (such as obtaining the consent of the subject of personal information, or being necessary for the performance of a contract, etc.), and will only be processed within the scope of regulations or agreements. If a user refuses to process personal information other than the necessary information for basic functions, it will not affect the user's use of basic functions.

[0027] The term "vehicle" as used herein includes vehicles having two, three, four, and more wheels, such as bicycles, multi-passenger bicycles, electric vehicles, cars, etc. In some embodiments, the vehicle may include a shared vehicle.

[0028] As briefly mentioned above, it is worth noting how to accurately determine whether a shared vehicle is parked in a designated area. The current shared vehicle return process is: the shared bicycle operator needs to return the vehicle in the parking spot designed on the road in advance. Specifically, the user performs a predetermined return / lock operation in the corresponding shared vehicle application installed on an electronic device such as a mobile phone. The application uses the positioning module (e.g., GPS) of the electronic device to obtain the user's location information. The application sends the acquired user's location information to the server. The server determines whether the user and the vehicle are both within the preset area (hereinafter referred to as the parking spot) where the vehicle can be parked. If the server determines that the user and the vehicle are within the parking spot, the return is allowed to be confirmed. If it is determined that either the user or the vehicle is not within the parking spot or the user and the vehicle are not within the parking spot, the return is not allowed. How to determine whether the parking position of a shared bicycle is within the parking spot range, the current solution depends on the accuracy of the positioning of the electronic device (e.g., mobile phone) and the accuracy of the positioning of the vehicle. However, both the electronic device positioning and the vehicle positioning will be affected to varying degrees by environmental factors such as the network and signal, and the problem of inaccurate positioning often occurs. That is, the vehicle and the user are clearly within the parking spot, but due to inaccurate positioning, when returning the vehicle, it is often judged as not being at the parking spot and a dispatch fee needs to be paid.

[0029] According to some embodiments of the present disclosure, a vehicle positioning solution is provided. In this solution, there is no longer a strong reliance on the positioning function of the electronic device or the positioning function of the vehicle. In this solution, magnets are arranged in the parking spot, and an electromagnetic induction sensor (also referred to as a vehicle-mounted magnetic sensor) can be installed in the shared vehicle. The magnetic field strength sensed by the electromagnetic induction sensor in the shared vehicle is used to assist in determining whether the current parking position of the vehicle is within the range of the parking spot.

[0030] Specifically, according to some embodiments of the present disclosure, a vehicle positioning solution is provided, which can be executed at a vehicle. The solution includes: determining the magnetic field strength sensed at the current location of the vehicle, and obtaining a target parameter based on the magnetic field strength. The vehicle can send at least the target parameter to the server. In this way, the server can determine whether the current location of the vehicle is located in a preset area where the vehicle can be parked based on the target parameter. A plurality of magnets arranged in a predetermined polarity order are provided in the preset area, and a sub-area where the vehicle can be parked is formed between two adjacent magnets with different polarities.

[0031] In this way, the intensity of the magnetic field sensed by the electromagnetic induction sensor in the shared vehicle is used to determine whether the current parking position of the vehicle is within the parking spot range, without relying on the positioning function of the vehicle or electronic equipment. The solution provided by the embodiment of the present disclosure can improve the accuracy of vehicle positioning, reduce the troubles and inconveniences encountered by users in the process of parking their vehicles, and enhance the user's car experience.

[0032] Example scenario

[0033] Figure 1 A schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented is shown. In the environment 100, a vehicle 110 and a server 120 may be included.

[0034] In the embodiment of the present disclosure, the vehicle 110 may be an electric vehicle, a car, a bicycle, etc. In the environment 100 of the embodiment of the present disclosure, the vehicle 110 may be a shared vehicle. Some embodiments below are described by taking the vehicle as a shared vehicle as an example.

[0035] The server 120 may be configured to centrally manage and control the vehicles 110. In some embodiments, the server 120 may be implemented as an independent server or a server cluster consisting of multiple servers. Any vehicle 110 and the server 120 may communicate with each other. The communication may be performed through any appropriate communication network and using any appropriate communication technology.

[0036] In some embodiments of the present disclosure, the environment 100 may further include an electronic device 130. The electronic device 130 may include, but is not limited to, electronic devices such as personal computers, mobile phones, tablet computers, and navigators. A shared vehicle application 140 may be installed and run on the electronic device 130, and an interface 141 may be presented for operation by the user 150. For example, a user may scan a shared vehicle for use through the "Scan code to use the vehicle" function provided by the interface 141, search for nearby vehicles through the "Map to find a vehicle" function provided by the interface 141; search for parking spots that can be used to park a shared vehicle through the "Search parking spots" function; and report a faulty shared vehicle through the "Find a broken vehicle" function.

[0037] The electronic device 130 may have a communication module to achieve communication with the vehicle 110 and communication with the server 120. The communication module may include a short-range communication module, such as a Bluetooth module. The electronic device 130 and the vehicle 110 may communicate via the short-range communication module. The communication module may also include a long-range communication module, such as a subscriber identification module (SIM). The electronic device 130 and the server 120 may communicate via the long-range communication module. The electronic device 130 may also have a positioning module, such as a global positioning system (GPS) positioning module, to achieve a positioning function.

[0038] Some exemplary structures of vehicle 110 are described below.

[0039] In some embodiments of the present disclosure, a controller such as a central control unit may be provided inside the vehicle 110. The central control unit may be configured to manage and control the functions of the vehicle 110. In some embodiments, the central control unit may communicate with the server 120 and the electronic device 130 wirelessly, respectively. In some embodiments, the electronic device 130 may also communicate with the server 120 wirelessly. In some embodiments, the server 120 may manage and control the vehicle 110 at least by communicating with the central control unit on the vehicle 110.

[0040] In some embodiments of the present disclosure, the vehicle 110 may also be provided with a positioning module, such as a GPS positioning module, to implement a positioning function.

[0041] In some embodiments of the present disclosure, a communication module may also be provided inside the vehicle 110 to enable communication between the vehicle 110 and the electronic device 130 and between the vehicle 110 and the server 120. The communication module may include a short-range communication module, such as a Bluetooth module. The vehicle 110 and the electronic device 130 may communicate via the short-range communication module. The communication module may also include a long-range communication module, such as a SIM. The vehicle 110 and the server 120 may communicate via the long-range communication module.

[0042] In some embodiments of the present disclosure, an electromagnetic induction sensor 111 is further provided in the vehicle 110. The electromagnetic induction sensor 111 may be, for example, a fluxgate current sensor or a Hall current sensor, etc. The electromagnetic induction sensor 111 may be arranged at any appropriate position in the vehicle 110. For example, an electromagnetic induction sensor is arranged on the wheel hub of the front wheel of the vehicle. Of course, the arrangement of the electromagnetic induction sensor 111 does not affect the normal use of the vehicle 110. The electromagnetic induction sensor provided on the vehicle 110 can be connected to the central control unit of the vehicle 110. In this way, the electromagnetic induction sensor can communicate with the central control unit.

[0043] It should be understood that the structure and functionality of environment 100 are described for exemplary purposes only and does not imply any limitation on the scope of the present disclosure.

[0044] Figure 2 A schematic diagram of an example parking area for parking vehicles provided by an embodiment of the present disclosure is shown. Figure 2In the example, a plurality of magnets arranged in a predetermined polarity order may be provided in the parking area 200 in any appropriate manner. The predetermined polarity here may be, for example, an order such as NSSNNSSN or SNNSSNNS. The magnet may be, for example, a permanent magnet. Two adjacent magnets with different polarities form a sub-area where a vehicle can be parked. That is, a magnet pair consisting of two magnets with different polarities can indicate a sub-area. Two adjacent magnets in different magnet pairs have the same polarity, and these two magnets with the same polarity repel each other so that different sub-areas do not interfere with each other. Figure 1 In the example, a sub-area 210 where a vehicle can be parked is formed between two adjacent magnets, a magnet 211 with the polarity of "S" and a magnet 212 with the polarity of "N". As an example, each magnet may be a certain distance above the ground, for example, 10 cm. Correspondingly, the electromagnetic induction sensor 111 in the vehicle 110 may also be set at an appropriate position of the vehicle 110 so that the electromagnetic induction sensor 111 can sense the magnetic field of the magnet pair. Specifically, the distance between the position where the electromagnetic induction sensor is located and the plane where the vehicle is parked may be a preset height, for example, 5 cm-15 cm. The preset height may be determined according to actual conditions so that the electromagnetic induction sensor can sense the magnetic field strength in the parking area. In some embodiments of the present disclosure, for each sub-area in the parking area, an arrow may be shown in each sub-area to guide the user to correctly place the vehicle 110. Figure 1 In the example of FIG. 1 , an arrow 213 is marked in the sub-area 210 to guide the user to park the vehicle 110 in the direction indicated by the arrow 213 .

[0045] Figure 3 The process 300 of vehicle positioning provided by the embodiment of the present disclosure is shown. Figure 1 The environment 100 and Figure 2 Parking area 200 is shown to describe process 300 .

[0046] At block 310 , the vehicle 110 determines the strength of the magnetic field sensed at the current location of the vehicle 110 .

[0047] At block 320 , the vehicle 110 obtains a target parameter based on the magnetic field strength.

[0048] In the disclosed embodiment, the target parameter may be at least one of the following: the magnetic field strength sensed by the vehicle 110 , a voltage value obtained by the vehicle 110 based on the sensed magnetic field strength, or a current value obtained based on the sensed magnetic field strength.

[0049] As mentioned above, the vehicle 110 may be provided with an electromagnetic induction sensor. In the disclosed embodiment, in block 310, the vehicle 110 may sense the surrounding magnetic field based on the electromagnetic induction sensor. Further, the electromagnetic induction sensor may obtain electrical parameters such as the magnitude of the electromotive force voltage and the magnitude of the current based on the magnitude of the sensed magnetic field strength.

[0050] As mentioned above, in Figure 2 In the example, a plurality of magnets arranged in a predetermined polarity sequence are provided in the preset area where the vehicle can be parked, and two adjacent magnets with different polarities form a sub-area where the vehicle can be parked. If the current position of the vehicle 110 is located in the preset area where the vehicle can be parked, the vehicle 110 can detect the magnetic field strength in the preset area through the electromagnetic induction sensor.

[0051] At block 330 , the vehicle 110 sends at least the target parameters to the server 120 .

[0052] As mentioned above, the vehicle 110 includes a central control unit. The electromagnetic induction sensor can be connected to the central control unit. In this way, the central control unit can obtain the magnetic field strength, electromotive force voltage, current magnitude, etc. sensed by the electromagnetic induction sensor in real time.

[0053] In some embodiments, when the user needs to return the vehicle, he may perform predetermined operations such as returning the vehicle / locking the vehicle in the shared vehicle application 140 in the electronic device 130. When the application 140 detects the user's operation, it may send a lock request to the server 120. In this case, the server will further determine whether the vehicle 110 is located in an area where vehicles can be parked based on the target parameters obtained from the vehicle 110.

[0054] In some embodiments, when the user returns the vehicle, the user may perform a predetermined operation such as returning the vehicle / locking the physical lock or hardware lock of the vehicle 110. After receiving such a predetermined operation instructing locking, the vehicle 110 (e.g., the central control unit in the vehicle 110) may send a lock request and a target parameter to the server 120. It is understandable that the vehicle 110 may carry the target parameter in the lock request, or may send the lock request and the target parameter separately.

[0055] In block 340 , the server 120 determines whether the current location of the vehicle 110 is located in a preset area where the vehicle can be parked based on the target parameters.

[0056] In some embodiments, if the server 120 determines that the target parameter is greater than a preset threshold value corresponding to the target parameter, it can determine that the current location of the vehicle 110 is located in a preset area where the vehicle can be parked. For example, if the server 120 determines that the detected magnetic field strength is greater than a preset magnetic field strength threshold value, or determines that the electromotive force voltage or current is greater than a corresponding threshold value, it determines that the current location of the vehicle 110 is located in a preset area where the vehicle can be parked.

[0057] In some embodiments of the present disclosure, if the server 120 determines that the current location of the vehicle 110 is located in a preset area where vehicles can be parked, it can send a lock-permitting instruction to the vehicle 110. Accordingly, the vehicle 110 receives the lock-permitting instruction from the server 120. In response to the instruction, the physical lock or hardware lock of the vehicle 110 is closed, completing the vehicle return process.

[0058] In this way, the magnetic field strength sensed by the electromagnetic induction sensor in the vehicle is used to determine whether the current parking position of the vehicle is within the parking point range, without relying on the positioning function of the vehicle or electronic equipment. The solution provided by the embodiment of the present disclosure can improve the accuracy of vehicle positioning, reduce the troubles and inconveniences encountered by users in the process of parking their vehicles, and enhance the user's car experience.

[0061] At block 410 , the vehicle 110 determines the strength of the magnetic field sensed at the vehicle's current location.

[0062] At block 420 , the vehicle 110 obtains a target parameter based on the magnetic field strength.

[0063] In box 430, the vehicle 110 sends at least the target parameters to the server 120 so that the server 120 determines whether the current location of the vehicle 110 is located in a preset area where the vehicle can be parked based on the target parameters. A plurality of magnets arranged in a predetermined polarity order are provided in the preset area, and a sub-area where the vehicle can be parked is formed between two adjacent magnets with different polarities.

[0064] In some embodiments, the target parameter includes at least one of the following: magnetic field strength, a voltage value obtained based on the magnetic field strength, or a current value obtained based on the magnetic field strength.

[0068] At block 510 , the server 120 receives target parameters from the vehicle 110 , where the target parameters are obtained based on the strength of the magnetic field sensed by the vehicle 110 .

[0069] In box 520, the server 120 determines whether the current location of the vehicle 110 is located in a preset area where the vehicle can be parked based on the target parameters. A plurality of magnets arranged in a predetermined polarity order are arranged in the preset area, and a sub-area where the vehicle can be parked is formed between two adjacent magnets with different polarities.

[0070] In some embodiments, the target parameter includes at least one of the following: magnetic field strength, a voltage value obtained based on the magnetic field strength, or a current value obtained based on the magnetic field strength.

[0071] In some embodiments, determining whether the current location of the vehicle is located in a preset area where the vehicle can be parked based on the target parameter includes: the server 120 determines that the current location of the vehicle 110 is located in a preset area where the vehicle can be parked in response to determining that the target parameter is greater than a preset threshold corresponding to the target parameter.

[0072] In some embodiments, the process 500 further includes: in response to determining that the current location of the vehicle 110 is located in a preset area where vehicles can be parked, the server 120 sends a locking permission indication to the vehicle 110 .
