And after the server preliminarily determines that the vehicle to be returned does not meet the angle parking condition, the server sends a first message to the mobile terminal so that the mobile terminal can display the operation control, and responds to a first operation instruction of the user to the operation control, and outputs a first prompt message so as to guide the user to execute code scanning operation, so that the vehicle returning experience of the user is improved. Further, after the server judges that the vehicle to be returned does not meet the angle parking condition according to the first parking angle, the server sends a second message to the mobile terminal, so that the mobile terminal outputs second prompt information to remind a user of changing the parking angle of the vehicle to be returned, and the vehicle to be returned is guaranteed to be parked in a standard mode.

The following method of fig. 9 may be included between S701 and S702.

Fig. 9 is a flowchart of a method for transmitting a second parking angle according to an embodiment of the disclosure. As shown in fig. 9, the method includes:

s901, the mobile terminal sends terminal position information to a server.

S902, the vehicle to be returned sends vehicle position information to the server.

And S903, judging whether the vehicle to be returned is in the parking spot by the server according to the terminal position information and/or the vehicle position information.

If so, then S904 is performed, otherwise, S905 is performed.

And S904, the server receives a second parking angle sent by the vehicle to be returned.

In some embodiments, prior to S904, the pending vehicle sends a second parking angle to the server.

S905, the server sends a fourth message to the mobile terminal.

The fourth message instructs the mobile terminal to output a fourth prompt.

The fourth prompting message is used for indicating the user to go to the parking spot.

And S906, the mobile terminal outputs fourth prompt information.

In some embodiments, the fourth prompting message includes, for example: the text "vehicle no longer stop! Please confirm whether the dispatch fee is paid to finish returning to the car? "," yes "control, and" no "control.

In some embodiments, if the mobile terminal receives a selection operation on the "yes" control (indicating that the user needs the dispatcher to park the to-be-returned vehicle to the parking spot), the server controls the to-be-returned vehicle to perform a locking operation, and if the mobile terminal receives a selection operation on the "no" control (indicating that the user needs to park the to-be-returned vehicle to the parking spot in a self-service manner), the mobile terminal sends a vehicle returning request to the server again.

Further, on the basis of any of the above embodiments, after or before the server determines that the vehicle to be returned meets the angular parking condition, or the server determines that the vehicle to be returned is within the parking spot, the vehicle returning method provided by the present disclosure further includes the method shown in fig. 10.

Fig. 10 is a flowchart of a method for determining whether a pending vehicle is stationary according to an embodiment of the present disclosure. As shown in fig. 10, the method includes:

s101, the mobile terminal obtains the motion information of the mobile terminal and the Bluetooth signal intensity between the mobile terminal and a vehicle to be returned.

In some embodiments, the motion information of the mobile terminal is obtained by performing information acquisition on the mobile terminal through a motion sensor (e.g., a speed sensor, an acceleration sensor, etc.) provided in the mobile terminal.

In some embodiments, the motion information of the mobile terminal includes a velocity and/or an acceleration of the mobile terminal.

In some embodiments, the bluetooth signal strength is obtained by scanning a bluetooth signal broadcasted by the vehicle to be returned through a bluetooth device arranged in the mobile terminal.

S102, the mobile terminal judges whether the motion information of the mobile terminal meets a first condition and whether the Bluetooth signal intensity is larger than a preset value.

S103, when the mobile terminal determines that the motion information of the mobile terminal meets the first condition and the Bluetooth signal intensity is larger than a preset value, the mobile terminal sends a third message to the server.

And the third message is used for instructing the server to control the vehicle to be returned to execute locking operation.

The first condition, the preset value, may be data information pre-stored in the mobile terminal.

The motion information of the mobile terminal meets a first condition, and the mobile terminal is in a static state.

The Bluetooth signal intensity is larger than the preset value, which indicates that the user is together with the vehicle to be returned.

It should be noted that, when the bluetooth signal intensity is greater than the preset value and the motion information of the mobile terminal meets the first condition, it may indicate that the vehicle to be returned is in a stationary state.

In some embodiments, when the motion information of the mobile terminal includes a velocity and an acceleration of the mobile terminal, the first condition may include, for example: -1.2 m/s (velocity) -0.2 m/s2 (acceleration).

In some embodiments, the mobile terminal may send the motion information and bluetooth signal strength to the server.

And S104, when the server determines that the vehicle to be returned meets the angle parking condition and receives a third message sent by the mobile terminal, the server controls the vehicle to be returned to execute locking operation.

The third message is sent when the mobile terminal acquires the motion information of the mobile terminal and the Bluetooth signal intensity between the mobile terminal and the vehicle to be returned and determines that the motion information of the mobile terminal meets the first condition and the Bluetooth signal intensity is larger than a preset value.

Please refer to fig. 2 and fig. 7, which are not repeated herein, for a method for determining that a vehicle to be returned meets the angular parking condition.

When the mobile terminal sends the motion information and the Bluetooth signal intensity of the mobile terminal to the server, the server controls the vehicle to be returned to execute locking operation when the server determines that the motion information of the mobile terminal meets the first condition and the Bluetooth signal intensity is larger than a preset value. The first condition and the preset value may be data information pre-stored in the server.

In some embodiments, after receiving the bluetooth signal strength, the server may determine whether the vehicle to be returned is in a stationary state according to the bluetooth signal strength and second movement information (of the vehicle to be returned) sent by the vehicle to be returned, and if so, control the vehicle to be returned to perform a locking operation.

Specifically, when the intensity of the bluetooth signal is greater than the preset value and the second motion information meets the first condition, it is determined that the vehicle to be returned is in a stationary state.

In some embodiments, after receiving the bluetooth signal intensity and the motion information of the mobile terminal, the server may determine whether the vehicle to be returned is in a stationary state according to the bluetooth signal intensity and second motion information (of the vehicle to be returned) sent by the vehicle to be returned, and if so, control the vehicle to be returned to perform a locking operation.

Specifically, when the intensity of the bluetooth signal is greater than the preset value and the second motion information and the motion information of the mobile terminal simultaneously satisfy the first condition, it is determined that the vehicle to be returned is in a stationary state.

The second motion information includes a speed and/or an acceleration of the vehicle to be returned.

Specifically, please refer to S206 for a method for the server to control the vehicle to be returned to perform the locking operation, which is not described herein again.

In some embodiments, before S101, further comprising: the method comprises the steps that a vehicle to be returned sends first motion information (g-sensor information) of the vehicle to be returned to a server; the server primarily judges whether the vehicle to be returned is in a static state or not according to the first motion information of the vehicle to be returned; if yes, controlling the vehicle to be returned to execute locking operation; and if not, sending a fifth message to the mobile terminal, wherein the fifth message is used for enabling the mobile terminal to output fifth prompt information. Further, the mobile terminal outputs fifth prompt information, and the fifth prompt information is used for reminding the user that the vehicle and the person are moving.

In some embodiments, the mobile terminal performs S101 after receiving the fifth message.

In the car returning method provided in fig. 10, the motion information of the mobile terminal meets the first condition, and the bluetooth signal intensity is greater than the preset value, which indicates that the car to be returned is in a static state, so that the mobile terminal sends the third message to the server, and when it is determined that the car to be returned meets the angle parking condition and the third message sent by the mobile terminal is received, the server can control the car to be returned to execute the locking operation, thereby preventing the user from forgetting to return the car, avoiding the car to be returned from being ridden by other people, and improving the car returning experience of the user.
