Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present application, it is further noted that, unless expressly stated or limited otherwise, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

It should be noted that in the embodiments of the present application, the term "comprising" is used to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.

The sharing electric motor car still car mode divide into has the stake to return the car and does not have the stake to return the car. The pile-equipped vehicle returning needs to be provided with the parking pile loading in advance at the parking position, so that a large amount of space is occupied, and the matching cost is increased. Therefore, most of the current shared electric vehicles adopt the mode of GPS positioning to assist returning.

When the shared electric vehicle is returned, the position of the shared electric vehicle to be returned is usually located by a GPS, and whether the position is located in the parking area is determined. The positioning accuracy of the GPS is usually 5 to 30 meters, and in addition, the positioning accuracy of the GPS is also affected by the surrounding environment or weather, which increases the positioning error, and eventually causes the shared electric vehicle to be unable to accurately park at a designated position.

When the GPS positioning system assists in returning the vehicle, although a parking area is set up in advance, the positioning accuracy of the GPS positioning system is not high, so that the shared electric vehicle can be identified as being in the parking area even if being parked outside the parking area, the problems of disordered parking, road occupation, traffic obstruction, public space occupation and the like are easy to occur, and the disordered parking mode seriously influences the traffic safety and the city appearance environment.

Secondly, the shared electric vehicle may be parked in the parking area but positioned outside the parking area, which may cause the user not to return the shared electric vehicle normally, and reduce the user experience.

In order to solve the technical problem, the inventor provides a shared electric vehicle returning assembly and a shared electric vehicle returning system after research. The shared electric vehicle returning assembly and the shared electric vehicle returning system are described in detail below with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic view of a shared electric vehicle returning assembly 10 according to an embodiment of the present application. In the present embodiment, the shared electric vehicle returning assembly 10 includes an ECU (Electronic Control Unit) 11, an RFID tag 12 and an RFID card reading module 13.

The RFID tag 12 is arranged on the ground of a parking area, and the RFID card reading module 13 is arranged on the shared electric vehicle 14; the RFID card reading module 13 is configured to read the RFID tag 12, and send information of the RFID tag 12 to the ECU11 after reading the RFID tag 12.

The ECU11 is configured to generate a lock command for locking the shared electric vehicle after receiving the information of the RFID tag 12 sent by the RFID card reading module 13, and complete the returning operation.

In the above embodiment, since the identification range of the RFID identification technology is small, and the ECU11 generates the car locking instruction only after receiving the information of the RFID tag 12, compared with the car returning technology assisted by GPS positioning, the positioning accuracy is higher, and the shared electric vehicle 14 can be prevented from being parked in a place far from a preset parking area, and the parking position is standardized.

For example, an RFID card reading module 13 is first installed on each shared electric vehicle 14, and a corresponding RFID tag 12 is installed on the ground in a preset parking area. After the user uses the shared electric vehicle 14, a vehicle returning request can be initiated through a corresponding application program, after the vehicle returning request is initiated, the RFID card reading module 13 starts to read the RFID tag 12, after the RFID card reading module 13 reads the corresponding RFID tag 12 information, the read RFID tag 12 information is sent to the ECU11, and after the ECU11 receives the RFID tag 12 information, a vehicle locking instruction is generated, the shared electric vehicle 14 is locked, and the vehicle locking operation is completed.

That is, when the RFID card reading module 13 does not read the RFID tag 12 information, the ECU11 cannot receive the corresponding RFID tag 12 information, and therefore, the car locking instruction is not generated, and finally the car returning operation cannot be completed. Because the identification range of the RFID tag 12 is small, generally within 30cm, the shared electric vehicle 14 is returned to the vehicle by the RFID identification technology, so that the shared electric vehicle 14 can be returned to the vehicle only in a fixed parking area, and the phenomenon of random parking and disorderly occurrence is reduced. In addition, the RFID card reading module 13 and the RFID tag 12 required by the RFID identification technology have lower cost compared with a high-precision GPS positioning system, and the cost can be reduced while the high-precision positioning is ensured by using the RFID identification technology to realize the returning operation of the shared electric vehicle 14.

Optionally, in this embodiment, the RFID tag 12 may be a passive tag, which has a strong anti-interference capability and does not need to be provided with a battery.

Optionally, referring to fig. 2, fig. 2 is a schematic view of the RFID card reading module 13 according to an embodiment of the present application. In this embodiment, the RFID card reading module 13 includes an RFID card reader 131 and an antenna 132, and the RFID card reader 131 is connected to the power supply of the shared electric vehicle 14 and is powered by the power supply of the shared electric vehicle 14.

In the RFID identification technology, the RFID card reader 131 needs a power supply, and the RFID card reader 131 in this embodiment is disposed on the shared electric vehicle 14 and connected to the power supply of the shared electric vehicle 14, so that the power supply of the shared electric vehicle 14 can supply power to the RFID card reader 131 without separately disposing a cable and a power supply, thereby further reducing the manufacturing cost.

Optionally, referring to fig. 3, fig. 3 is a schematic view of an installation position of the RFID card reading module 13 according to an embodiment of the present application. In one possible implementation, the RFID tag 12 comprises a low frequency tag, and in order to read the low frequency RFID tag 12, the RFID reader 131 therefore comprises a low frequency reader 1311.

When the RFID reader 131 employs the low frequency reader 1311, the antenna 132 is disposed on the kickstand 141 of the shared electric vehicle 14.

It is worth noting that in fig. 3, the low frequency card reader 1311 is disposed on the foot rest 140, but in other embodiments, the low frequency card reader 1311 may also be disposed on the footrest bracket 141 when the low frequency card reader 1311 is employed as the RFID card reader 131.

In this embodiment, the low frequency card reader 1311 may employ a 32-bit AMD processor, a communication carrier frequency of 134.2KHz, and the low frequency tag may be an EM4305 tag employing ISO11784/11785 protocol.

Optionally, referring to fig. 4, fig. 4 is a second schematic view of an installation position of the RFID card reading module 13 according to the embodiment of the present application. In one possible implementation, the RFID tag 12 comprises a high frequency tag, and in order to read the high frequency RFID tag 12, the RFID reader 131 therefore comprises a high frequency reader 1312.

When the RFID reader 131 employs the high frequency reader 1312, the antenna 132 is provided on the foot board 142 of the shared electric vehicle 14, and the high frequency reader 1312 is provided on the foot board.

In the above embodiment, the high frequency reader 1312 may employ a 32 bit AMD processor, a communication carrier frequency of 13.56MHz, and the high frequency tag may be an I-code2 tag employing the ISO15693 protocol.

In the implementation mode that adopts high frequency label and high frequency card reader 1312, the identification range of RFID identification technology is great, as long as high frequency card reader 1312 is located tens centimetres (for example 30cm) department above the position of high frequency label, can carry out reading of label information, go back the car, this kind of mode is still car comparatively convenient, and user's success rate of returning the car is higher, and user experience is better.

In the implementation mode of adopting the low-frequency tag and the low-frequency card reader 1311, the identification range of the RFID identification technology is small, and the tag information can be read only when the low-frequency card reader 1311 approaches the low-frequency tag by 1-2 cm, so that the position of a user returning to a car is more accurate, the phenomenon of random parking and random placement is further reduced, and the cost of the low-frequency scheme is lower than that of the high-frequency scheme.

With reference to fig. 5, fig. 5 is a schematic diagram illustrating a returning result of the shared electric vehicle 14 according to the embodiment of the present application. Alternatively, in the present embodiment, the RFID tags 12 are arranged on the same straight line within the parking area (as shown by the dotted line in fig. 5).

Because the RFID card reading module is arranged on the foot support or the foot pedal 142 of the shared electric vehicle 14, and the identification range of the RFID identification technology is small, if the user wants to successfully return to the vehicle, the user needs to park the foot support of the shared electric vehicle 14 close to the RFID tag 12 or park the bicycle of the shared electric vehicle 14 above the RFID tag 12; if the user only parks the shared electric vehicle 14 in the parking area at will, the RFID card reading module may not read the information of the RFID tag 12, resulting in a failure of returning the vehicle. Through this kind of mode for each shared electric motor car 14 can standardize and neatly park in the parking area, solve present shared electric motor car 14 and park the problem of irregularity.

Optionally, in this embodiment, the RFID tag 12 is embedded in a plastic material, so as to be able to withstand the temperature difference between winter and summer, and not be affected by the weather environment such as rain, dew, frost or rain, and thus has a long service life.

Further, when the RFID tag 12 is fixed on the ground of the parking area, a layer of waterproof material can be coated outside the RFID tag 12, so that the waterproof performance of the RFID tag is further improved, and the service life of the RFID tag is prolonged.

The RFID card reading module adopts an IPX 7-level waterproof processing mode to carry out waterproof processing, and the normal work of the RFID card reading module cannot be influenced even in rainy days.

Optionally, in this embodiment, a waterproof housing is disposed outside the RFID card reading module 13. The waterproof shell can be made of aluminum or plastic, and can be manufactured in an integrated forming mode, so that rainwater is prevented from permeating into gaps.

Optionally, in this embodiment, a cavity is disposed on the pedal 142 of the shared electric vehicle 14 or the foot support 141 of the shared electric vehicle 14, the cavity is configured to receive the RFID card reading module 13, and the cavity is sealed by a waterproof adhesive.

In the implementation process of the above embodiment, after the waterproof housing is disposed outside the RFID card reading module 13, the RFID card reading module 13 may be placed in the cavity on the pedal 142 or the RFID card reading module 13 may be disposed in the cavity on the foot support 141, and then the cavity is closed by the cover, and waterproof glue is applied to the gap formed between the cavity and the cover to completely close the RFID card reading module 13.

Through the installation of the RFID card reading module 13 in the above manner, even if rain or water is accumulated on the road surface, the normal work of the RFID card reading module 13 is not influenced, and the normal operation of the returning process of the shared electric vehicle 14 is ensured.

Optionally, in this embodiment, the internal data of the RFID tag 12 may also be encrypted, so as to avoid malicious counterfeiting of the RFID tag 12.

Referring to fig. 6, fig. 6 is a schematic view of a shared electric vehicle returning system 1 according to an embodiment of the present application. In the present embodiment, the shared electric vehicle returning system 1 includes the client terminal 20, the server 30 and the shared electric vehicle returning assembly 10 provided in the foregoing embodiments. The client terminal 20 and the server 30 communicate via a network to enable data communication or interaction between the client terminal 20 and the server 30.

In some embodiments, the server 30 may be, but is not limited to, a web server, an ftp (file transfer protocol) server, and the like. The device type corresponding to the client terminal 20 may be a mobile device, such as a smart home device, a wearable device, a smart mobile device, or the like, or may be a tablet computer, a laptop computer, or the like. The network may be, but is not limited to, a wired network or a wireless network. The operating system of the client terminal 20 may be, but is not limited to, an Android system, an ios (internet operating system) system, a Windows phone system, a Windows system, and the like. The client terminal 20 may download applications required for installation, such as a browser (IE browser, UC browser, 360 browser, QQ browser, etc.) or other various applications, from the server 30 through the network. The application installed on the client terminal 20 can directly communicate and interact with the server 30.

In this embodiment, the client terminal 20 is configured to initiate a car return request to the server 30 for each car to be returned; the server 30 is configured to receive the returning request and initiate a locking request to the shared electric vehicle returning assembly 10.

The shared electric vehicle returning assembly 10 is configured to receive the vehicle locking request, judge whether the RFID card reading module 13 reads the information of the RFID tag 12 through the ECU11 after receiving the vehicle locking request, generate a vehicle locking instruction for locking the shared electric vehicle after reading the information of the RFID tag 12, and complete the vehicle returning operation.

In this embodiment, when the user needs to return the car, a car return request may be initiated on an application program or a small program of the client terminal 20, where the car return request includes car information and location information of a car to be returned, and after receiving the car return request initiated by the client terminal 20, the server 30 may first determine whether the car to be returned is located in a car return area, and if not, feed back information that is not in the car return area to the client terminal 20 to guide the user to move the car to be returned to the car return area; if the vehicle to be returned is in the vehicle returning area, the server 30 initiates a vehicle locking request to the shared electric vehicle returning assembly 10.

After receiving the locking request, the shared electric vehicle returning assembly 10 reads the information of the surrounding RFID tags 12 through the RFID card reading module 13, and sends the read tag information to the ECU11, and the ECU11 generates a vehicle locking instruction for locking the shared electric vehicle after receiving the tag information, thereby completing the returning.

If the RFID card reading module 13 does not read the RFID tag 12 information, it indicates that the vehicle to be returned is not placed according to the requirement, and at this time, the tag information cannot be sent to the ECU11, and if the ECU11 does not receive the RFID tag 12 information within the preset time period, the tag information is fed back to the client terminal 20 to guide the user to place the vehicle to be returned again.

In another implementation manner of this embodiment, when the ECU11 detects that the vehicle speed of the shared electric vehicle 14 is lower than a preset threshold, the ECU11 sends an instruction to the RFID card reading module 13 to start the operation of the RFID card reading module 13 to read the RFID tag 12, when the user returns the vehicle through the client terminal 20, the ECU11 obtains the tag information of the RFID tag 12 read by the RFID card reading module 13, and in a case that the ECU11 can obtain the tag information, generates a vehicle locking instruction for locking the shared electric vehicle, and completes the vehicle returning; if the ECU11 cannot acquire the tag information, the car lock instruction cannot be generated, that is, the car cannot be returned.

Optionally, in this embodiment, the RFID card reading module 13 further includes a buzzer, and when the RFID card reading module 13 reads the RFID tag 12, the buzzer sends an alert sound to prompt the user that tag information has been currently read.

Optionally, referring to fig. 6, in the present embodiment, the shared electric vehicle returning system 1 further includes a prompting unit 40. The prompting unit 40 is disposed on the shared electric vehicle 14, and is in communication connection with the ECU11 of the shared electric vehicle returning assembly 10, and is used for giving a corresponding prompt to the user when the information of the RFID tag 12 is read.

The prompting unit 40 is further configured to prompt the user when the vehicle to be returned is located outside the vehicle returning area.

In the above embodiment, a prompting unit 40 is further disposed on the shared electric vehicle 14, and the prompting unit 40 may be one or more of a voice prompting component, a buzzer, or an indicator light. The prompting unit 40 is communicatively connected with the ECU11 and is used for prompting the user according to instructions sent by the ECU 11.

For example, when the user returns the car, if the ECU11 can receive the RFID tag 12 information sent by the RFID card reading module 13 or the car returning is successful, the ECU11 generates a control command for controlling the prompting unit 40 to prompt the user to read the RFID tag 12 or the car returning is successful.

Optionally, the client terminal 20 is further configured to receive a car return result prompt sent by the server 30, where the car return result prompt includes a car return success or a car return failure.

For example, when the user is returning, if the ECU11 does not receive the RFID tag 12 information within a preset time period (for example, within 30 s), it indicates that the RFID module does not read the RFID tag 12 information, that is, the shared electric vehicle 14 to be returned is not placed according to the requirement, at this time, the ECU11 feeds back the information of failure to return to the vehicle to the client terminal 20 through the server 30, and after receiving the information of failure to return to the vehicle sent by the server 30, the client terminal 20 displays the information of failure to return to the vehicle on the display interface of the client terminal 20, so as to guide the user to correctly place the shared electric vehicle 14 to be returned according to the requirement.

In another embodiment, when the user returns the vehicle, the server 30 may determine whether the vehicle to be returned is located in the parking area according to the position information of the vehicle to be returned sent by the ECU11, if the vehicle to be returned is not located in the parking area, the server 30 feeds back information that the vehicle to be returned is not located in the parking area to the client 20, and the client 20 reminds the user through the display interface of the client 20 after receiving the feedback information: the pending vehicle is not currently located within the pending area to guide the user to park the pending shared electric vehicle 14 within the parking area.

In summary, the present application provides a shared electric vehicle returning assembly 10 and system, the shared electric vehicle returning assembly 10 includes an ECU11, an RFID tag 12 and an RFID card reading module 13. The RFID tag 12 is disposed on the ground of the parking area, and the RFID card reading module 13 is disposed on the shared electric vehicle 14. The RFID card reading module 13 is configured to read the RFID tag 12, send information of the RFID tag 12 to the ECU11 after reading the RFID tag 12, and the ECU11 is configured to generate a car locking instruction for locking the shared electric car after receiving the information of the RFID tag 12, so as to complete a car returning operation. Because the identification range of the RFID identification technology is small, and the ECU11 generates a car locking instruction only after receiving the information of the RFID tag 12, compared with the GPS positioning assisted car returning technology, the positioning accuracy is higher, and the shared electric car 14 can be prevented from being parked at a place far from a preset parking area to standardize the parking position.
