After receiving the vehicle returning request, the vehicle management system may send the vehicle returning request to the shared vehicle corresponding to the identification information of the shared vehicle, and after receiving the vehicle returning request sent by the vehicle management system, the shared vehicle may activate an NFC (Near Field Communication) reader-writer internally provided.

After the NFC reader is activated, the NFC reader can transmit radio frequency energy within a threshold time range to form an electromagnetic field, so that an NFC tag (NFC tag) is polled within the coverage range of the electromagnetic field, and returning positioning device information is acquired from the polled NFC tag. The threshold time range may be a preset time value, and the specific value may be determined according to an actual situation, for example: the preset time range may be set to 3 seconds.

And 204, under the condition of acquiring the information of the vehicle returning positioning device, performing vehicle returning processing according to the information of the vehicle returning positioning device.

and step 304, sending the first vehicle returning information to the vehicle management system, so that the vehicle management system determines the position information of the vehicle returning point where the shared vehicle is located according to the vehicle returning positioning device information, and returning the vehicle according to the position information.

In the embodiment of the present disclosure, after the returning vehicle positioning device information is acquired, first returning vehicle information including an identifier of the shared vehicle and the returning vehicle positioning device information may be generated according to the returning vehicle positioning device information, where the identifier of the shared vehicle may include, but is not limited to, information used for identifying the shared vehicle, such as a number of the shared vehicle. After generating the first vehicle returning information, the shared vehicle may send the first vehicle returning information to the vehicle management system. The vehicle management system can acquire the information of the vehicle returning positioning device from the first vehicle returning information after receiving the first vehicle returning information sent by the shared vehicle, determines the position information of the corresponding vehicle returning point through the information of the vehicle returning positioning device, further determines that the shared vehicle is located at the vehicle returning point, allows a user to return the vehicle, performs bill data interaction with the terminal, and completes the vehicle returning.

In one example, the shared vehicle may also actively acquire the vehicle returning positioning device information from the NFC tag in the vehicle returning positioning device through the NFC reader, and send the first vehicle returning information to the vehicle management system according to the vehicle returning positioning device information. The method comprises the steps that after a vehicle management system receives first vehicle returning information sent by a shared vehicle, vehicle returning positioning device information can be obtained from the first vehicle returning information, the corresponding position information of a vehicle returning point is determined through the vehicle returning positioning device information, the shared vehicle is further determined to be located at the vehicle returning point, prompt information can be sent to a mobile terminal, a user is prompted to be in the vehicle returning point at the moment through the prompt information, whether the vehicle is returned or not is judged, bill data interaction is carried out with the mobile terminal under the condition that the user triggers a vehicle returning request through the prompt information, and vehicle returning is completed.

According to the vehicle returning sharing method, the shared vehicle acquires the information of the vehicle returning positioning device from the NFC tag of the vehicle returning positioning device fixed on the ground of the vehicle returning point through the NFC reader, generates the first vehicle returning information according to the information of the vehicle returning positioning device under the condition of acquiring the information of the vehicle returning positioning device, and sends the first vehicle returning information to the vehicle management system, so that the vehicle management system returns the vehicle according to the information of the vehicle returning positioning device. Because NFC is near field communication, therefore only when the shared vehicle stops in the point of returning the bus accurately, the NFC label communication connection in the fixed locating device of returning the bus on the point of returning the bus can be obtained from the NFC label communication connection, and after obtaining the information of the locating device of returning the bus and generating the first information of returning the bus, the NFC label communication connection can indicate the vehicle management system to return the bus through the first information of returning the bus, so that the locating precision of the shared vehicle at the point of returning the bus can be improved, and accurate locating parking is realized.

In one embodiment, as shown in fig. 4, the acquiring, in step 202, returning location device information by the NFC reader may include:

step 402, receiving a positioning instruction sent by a mobile terminal;

and step 404, acquiring the returning positioning device information through the NFC reader-writer according to the positioning instruction.

In the embodiment of the disclosure, when the user uses the shared vehicle, the mobile terminal can automatically establish bluetooth connection with the shared vehicle, and when the user needs to return to the vehicle, the user can operate the mobile terminal to acquire the parking information of the shared vehicle through bluetooth polling. For example, the mobile terminal may transmit a location indication to the location management device of the shared vehicle via bluetooth in response to a return operation of the user. After the sharing bicycle receives the positioning instruction sent by the mobile terminal through the Bluetooth, the NFC reader-writer can be activated according to the positioning instruction, then the NFC label is polled in the threshold time range through the NFC reader-writer, the returning positioning device information is obtained, and then returning processing is carried out according to the returning positioning device information.

In one embodiment, in step 204, the returning process is performed according to the returning location device information, and includes:

and sending the returning positioning device information to the mobile terminal so that the mobile terminal sends second returning information to the vehicle management system according to the returning positioning device information, so that the vehicle management system determines the position information of a returning point where the shared vehicle is located according to the returning positioning device information, and returns the vehicle according to the position information.

In the embodiment of the disclosure, after obtaining the returning positioning device information, the shared vehicle can send the returning positioning device information to the mobile terminal. After receiving the returning positioning device information, the mobile terminal can send second returning information to the vehicle management system according to the returning positioning device information, the second returning information can include the returning positioning device information, and then the vehicle management system can determine the position information of a returning point where the shared vehicle is located according to the returning positioning device information and return the vehicle according to the position information.

In one embodiment, the shared vehicle returning method may further include:

and under the condition that the information of the vehicle returning positioning device is not acquired, sending first prompt information to the mobile terminal, wherein the first prompt information is used for representing that the shared vehicle is not in a vehicle returning area.

In the embodiment of the disclosure, under the condition that the shared vehicle does not acquire the information of the returning positioning device within the threshold time range, the first prompt information can be sent to the mobile terminal, and the terminal device can correspondingly display the first prompt information in the display interface, so that the user is prompted by the first prompt information that the shared vehicle is not in the returning area, and is in illegal parking at the moment.

For example, as shown in fig. 5 and 6, when the user uses the shared vehicle, the mobile terminal may automatically establish a bluetooth connection with the shared vehicle, and when the user needs to go back to the vehicle, the mobile terminal may acquire the location information of the shared vehicle by bluetooth polling. The shared vehicle receives a positioning instruction through bluetooth in a positioning management device (shown in fig. 7, the device is composed of an NFC coil, an NFC reader, a bluetooth SOC and a built-in power supply device), activates the NFC reader according to the positioning instruction, and polls and reads returning positioning device information of the returning positioning device on the ground through the NFC reader. After the shared vehicle completes the fixed-point parking according to the regulations, the NFC coil of the shared vehicle is just positioned on the vehicle returning positioning device, so that the NFC reader-writer can read the information of the vehicle returning positioning device from the NFC label through the NFC coil, the shared vehicle can be judged to be accurately parked at the moment, and the information of the vehicle returning positioning device can be sent to the mobile terminal through Bluetooth. Because the reading distance of the NFC reader is limited, if the shared vehicle is not parked at an appointed place, the NFC reader cannot read appointed label information, the shared vehicle is judged to be illegally parked at the moment, and first prompt information can be sent to the mobile terminal through the Bluetooth module.

And if the mobile terminal receives the returning positioning device information fed back by the shared vehicle through the Bluetooth module, second returning information is sent to the vehicle management system according to the returning positioning device information, and the vehicle management system sends a returning locking instruction to the shared vehicle according to the returning positioning device information to complete the whole returning operation. If the mobile terminal receives the first prompt information fed back by the shared vehicle through the Bluetooth module, the mobile terminal correspondingly displays the first prompt information in a display interface, or can also display information such as fixed-point parking requirement guide of a user and the like.

According to the shared vehicle returning method, the mobile terminal is in Bluetooth communication with the shared vehicle positioning management device, so that the parking information of the shared vehicle can be acquired, and accurate entering judgment can be further realized.

step 802, receiving positioning broadcast information sent by a returning positioning device;

and step 804, after the positioning broadcast information is received, polling the NFC tag through the NFC reader within a threshold time range to acquire the returning positioning device information of the returning positioning device from the NFC tag.

After receiving the positioning broadcast information sent by the vehicle returning positioning device, the sharing vehicle can activate the NFC reader-writer, and control the NFC reader-writer to poll the NFC tag within the threshold time range, so as to acquire the vehicle returning positioning device information of the vehicle returning positioning device from the NFC tag, and the specific process can be performed by referring to the foregoing related description, which is not described in detail in the embodiment of the present disclosure.

Based on the shared vehicle returning method provided by the embodiment of the disclosure, the NFC reader-writer of the shared vehicle can be activated to perform NFC tag polling through the positioning broadcast information sent by the returning positioning device, that is, the NFC reader-writer of the shared vehicle does not need to be always in an activated state, and the NFC reader-writer of the shared vehicle is activated to perform positioning only when the shared vehicle is determined to be near a returning point through the positioning broadcast information sent by the returning positioning device, so that the power consumption of the NFC reader-writer on the shared vehicle can be reduced, and the energy consumption is saved.

In one embodiment, as shown in fig. 9, in step 804, after receiving the positioning broadcast information, polling the NFC tag by the NFC reader within the threshold time range includes:

step 902, after receiving the positioning broadcast information, determining the signal strength of the positioning broadcast information;

and 904, polling the NFC tag through the NFC reader within a threshold time range when the signal strength of the positioning broadcast information is greater than or equal to the signal strength threshold.

In the embodiment of the present disclosure, after receiving the positioning broadcast information sent by the returning positioning device, the sharing vehicle may determine a Received Signal Strength Indicator (RSSI) of the positioning broadcast information. It should be noted that, in the embodiment of the present disclosure, a detection method of the signal strength is not specifically limited, and all the ways that the RSSI value detection can be implemented are applicable to the embodiment of the present disclosure.

After the signal strength of the positioning broadcast information is determined, it is determined whether the signal strength of the positioning broadcast information is greater than or equal to a signal strength threshold, and under the condition that the signal strength of the positioning broadcast information is greater than or equal to the signal strength threshold, it may be determined that the shared vehicle is already near the returning positioning device, and then the NFC reader-writer may be activated to acquire returning positioning device information (for a specific process, reference may be made to the foregoing embodiment, and details of the embodiment of the present disclosure are not repeated here). The signal intensity threshold may be a preset value, and may be a value according to a requirement.

Based on the shared vehicle returning method provided by the embodiment of the disclosure, the NFC reader-writer is not required to be always in an activated state, and only when the positioning broadcast information sent by the vehicle returning positioning device is received and the signal intensity of the positioning broadcast information is greater than or equal to the signal intensity threshold value (at the moment, the shared vehicle is close to the vehicle returning positioning device enough), the NFC reader-writer is activated to acquire the vehicle returning positioning device information, so that the power consumption of the NFC reader-writer on the shared vehicle can be reduced, and the energy consumption is saved.

In one embodiment, the shared vehicle returning method may further include:

and under the condition that the positioning broadcast information is not received or the signal intensity of the positioning broadcast information is smaller than the signal intensity threshold value, third returning information is sent to the vehicle management system, so that the vehicle management system sends second prompt information to the mobile terminal according to the third returning information, and the second prompt information is used for representing that the shared vehicle is not in the parking area.

In the embodiment of the disclosure, the sharing vehicle may activate the short-range communication module (for example, devices such as bluetooth and UWB) based on a vehicle returning request issued by the vehicle management system, so as to scan and receive the positioning broadcast information sent by the vehicle returning positioning device through the short-range communication module. If the positioning broadcast information is not received within the threshold time range or the signal intensity of the received positioning broadcast information is smaller than the signal intensity threshold, it can be determined that the shared vehicle is far away from the vehicle returning positioning device, namely far away from a vehicle returning point, and the shared vehicle cannot return the vehicle, and the shared vehicle can send third vehicle returning information to the vehicle management system. After receiving the third vehicle returning information sent by the shared vehicle, the vehicle management system can send second prompt information to the mobile terminal, wherein the second prompt information is used for representing that the shared vehicle is not in the vehicle returning area.

For example: the second prompt message may be "the vehicle is not currently at the vehicle returning spot, the vehicle cannot be returned, and please move to the vehicle returning spot". The user can move the shared vehicle to a larger extent according to the second prompt message so as to move to a vehicle returning point for vehicle returning.

According to the shared vehicle returning method provided by the embodiment of the disclosure, under the condition that the shared vehicle does not receive the positioning broadcast information sent by the returning positioning device or the signal intensity of the positioning broadcast information is smaller than the signal intensity threshold value, the vehicle management system can be triggered to send the first prompt information to the mobile terminal through the second returning information, so that the user is prompted to reasonably move the shared vehicle through the first prompt information, and the returning efficiency is improved.

In one embodiment, after step 804, the shared vehicle returning method may further include:

and under the condition that the returning positioning device information is not received within the threshold time range, fourth returning information is sent to the vehicle management system, so that the vehicle management system sends third prompt information to the mobile terminal according to the fourth returning information, wherein the third prompt information is used for representing that the shared vehicle is in the parking area but not in the returning positioning device area.

In the embodiment of the disclosure, after the shared vehicle activates the NFC reader to poll the NFC tag, if the NFC tag is not polled within the threshold time range, that is, under the condition that the returning location device information is not received, it may be determined that the shared vehicle is closer to the returning location device, but is not within the returning point range corresponding to the returning location device, and at this time, the returning cannot be performed, and the shared vehicle may send fourth returning information to the vehicle management system. After receiving the fourth returning information sent by the shared vehicle, the vehicle management system may send third prompt information to the mobile terminal, where the third prompt information is used to indicate that the shared vehicle is in the returning area but not in the returning positioning device area.

For example: the third prompt message may be that the current distance from the vehicle returning point is short, and the vehicle position is required to be adjusted to the vehicle returning point. The user can move the shared vehicle in a small range according to the second prompt message so as to move the shared vehicle to a vehicle returning point for vehicle returning.

According to the shared vehicle returning method provided by the embodiment of the disclosure, after the NFC reader is activated by a shared vehicle and the returning positioning device information is not received within the threshold time range, the fourth returning information can trigger the vehicle management system to send the third prompt information to the mobile terminal, so that the user is prompted to reasonably move the shared vehicle through the third prompt information, and the returning efficiency is improved.

In one embodiment, referring to fig. 10, the step 204 includes:

step 1002, determining whether the shared vehicles meet vehicle returning conditions according to the vehicle returning positioning device information;

and 1004, under the condition that the shared vehicle meets the vehicle returning condition, generating first vehicle returning information according to the vehicle returning positioning device information.

In the embodiment of the disclosure, the shared vehicle may determine whether the shared vehicle meets the vehicle returning condition according to the vehicle returning positioning device information after acquiring the vehicle returning positioning device information, and the vehicle returning condition may be a condition for determining whether the shared vehicle can be returned at a vehicle returning point corresponding to the vehicle returning positioning device.

Illustratively, different regions can be divided for different vehicle types for returning. The vehicle returning condition may include that the vehicle returning positioning device corresponds to the same vehicle type as the shared vehicle (the vehicle type may include but is not limited to a bicycle, an electric vehicle, a car, and the like), after the shared vehicle acquires the vehicle returning positioning device information, the vehicle type corresponding to the vehicle returning positioning device may be acquired from the vehicle returning positioning device information, and compared with the vehicle type of the shared vehicle, and in the case that it is determined that the vehicle types are consistent, it may be determined that the shared vehicle meets the vehicle returning condition, and it may be determined that the shared vehicle may be returned at a vehicle returning point where the vehicle returning positioning device is located, so that first vehicle returning information may be generated according to the identifier of the shared vehicle and the vehicle returning positioning device information, and the first vehicle returning information is sent to the vehicle management system, so that the vehicle management system performs bill interaction with the shared vehicle according to the first vehicle returning information, and completes vehicle returning of the shared vehicle.

Or, under the condition that it is determined that the shared vehicle does not meet the vehicle returning condition, that is, when it is determined that the shared vehicle is not allowed to be returned at the vehicle returning point where the vehicle returning positioning device is located, fifth vehicle returning information may be generated according to the identifier of the shared vehicle and the vehicle returning positioning device information, and the fifth vehicle returning information is sent to the vehicle management system, so that the vehicle management system sends fourth prompt information to the mobile terminal according to the fifth vehicle returning information, where the fourth prompt information may be used to prompt the user of the current position of the unshared vehicle returning position, so as to instruct the user to move the shared vehicle to the corresponding vehicle returning position for returning.

Based on the shared vehicle returning method provided by the embodiment of the disclosure, the shared vehicle can be returned according to the vehicle type specification, the management mode of the shared vehicle can be enriched, the user experience is improved, and the standardability of parking the shared vehicle is improved.

In order that those skilled in the art will better understand the embodiments of the present disclosure, the embodiments of the present disclosure are described below by way of specific examples.

Referring to fig. 11, when a user initiates a vehicle return request through an APP installed on a terminal device, after receiving the vehicle return request, a vehicle management system sends the vehicle return request to a shared vehicle bound to the terminal device. After the sharing vehicle receives the vehicle returning request, bluetooth (such as BLE (Bluetooth Low Energy)) can be turned on to scan positioning broadcast information sent by the Bluetooth in the vehicle returning positioning device.

The returning positioning device periodically sends positioning broadcast information. If the shared vehicle is near the returning point, the shared vehicle detects the RSSI signal intensity of the positioning broadcast information after receiving the positioning broadcast information sent by the returning positioning device. If the signal intensity is larger than or equal to the signal intensity threshold value, the NFC reader-writer can be opened to read spike information in the NFC label in the spike, if the spike information is read within the threshold time range, the shared vehicle is indicated to be accurately parked at a vehicle returning point, and therefore first vehicle returning information can be sent to the vehicle management system according to the vehicle returning positioning device information and the identification of the shared vehicle. The vehicle management system can interact bill information with the mobile terminal according to the first vehicle returning information, after the vehicle returning is completed, a lock closing instruction is issued to the shared vehicle, and the shared vehicle locks the vehicle after receiving the lock closing instruction.

If the returning positioning device information is not read within the threshold time range, the shared vehicle is not accurately stopped at the returning point, and therefore fourth returning information can be sent to the vehicle management system. And the vehicle management system can send third prompt information to the mobile terminal according to the fourth vehicle returning information, and prompts the user to execute the vehicle returning operation again after the position of the shared vehicle is adjusted by a small margin until the vehicle returning operation is successful.

Or, if the signal strength of the positioning broadcast information is smaller than the signal strength threshold, it indicates that the shared vehicle is not accurately parked at the returning point and is far away from the returning positioning device, and therefore, the third returning information may be sent to the vehicle management system. The vehicle management system can send second prompt information to the mobile terminal according to the third vehicle returning information, and after prompting the user to greatly adjust the position of the shared vehicle, the vehicle returning operation is executed again until the vehicle returning is successful.

Alternatively, if the shared vehicle is not near the returning point, the shared vehicle does not receive the positioning broadcast information sent by the returning positioning device within the threshold time range, so that the sixth returning information can be sent to the vehicle management system. The vehicle management system can send fifth prompt information to the mobile terminal according to the sixth vehicle returning information to prompt that the user is not a vehicle returning point currently and the vehicle returning fails.

It should be understood that although the various steps in the flow diagrams of fig. 1-11 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not limited to being performed in the exact order illustrated and, unless explicitly stated herein, may be performed in other orders.

In the shared vehicle returning system, after the NFC reader 1322 of the shared vehicle 132 is activated, the radio frequency energy may be transmitted within the threshold time range, and after the NFC tag 1342 of the returning location device 134 fixed on the ground of the returning location is activated by the radio frequency energy transmitted by the NFC reader 1322, the returning location device information of the returning location device 134 may be transmitted to the NFC reader 1322 of the shared vehicle 132, and after the returning location device information of the returning location device 134 is received by the NFC reader 1342, the returning location device information is acquired from the NFC reader 1342 by the communicator 1324, and then returning processing is performed according to the returning location device.
