The posture sensor 371 is used for collecting posture data of the bicycle 300, which includes data content reflecting direction information of the bicycle 300, i.e., the direction of the bicycle 300 at a corresponding time can be obtained according to the posture data of the bicycle 300 at any time, e.g., the parking direction of the bicycle can be obtained according to the posture data of the bicycle, etc.

In this embodiment, the attitude sensor 371 is connected to the controller 310 so as to be able to transmit the acquired attitude data to the controller 310. The controller 310 can control the parking direction of the bicycle 300 according to the posture data; the controller 310 can also report the posture data to the server 100, and the server 100 controls the parking direction of the bicycle 300.

In one embodiment, the controller 310 may also be configured to: when the bicycle is detected to be parked in the designated parking area, acquiring gesture data acquired by a gesture sensor, and comparing the parking direction reflected by the gesture data with a standard parking direction corresponding to the parking position of the bicycle; and when the two are not consistent, prompting the user to adjust the parking direction of the vehicle to be consistent with the standard parking direction.

In this embodiment, the bicycle may detect whether the bicycle is parked in a designated parking area or the like by establishing a connection with a bluetooth device or a radio frequency identification device provided in the parking area, which is not limited herein.

In one embodiment, the controller 310 may also upload the acquired pose data to a server and perform the above comparison by the server.

For example, the controller 310 of the bicycle 300 regularly reports the posture data of the bicycle 300 to the server 1000 at set time intervals. In this embodiment, after receiving the locking request, the server 100 may determine the parking direction of the vehicle according to the attitude data reported by the vehicle last time.

In this example, the time interval may be set to have a shorter time length to improve the accuracy of determining the parking direction of the vehicle according to the latest reported posture data of the bicycle 300, for example, the time interval is 1 min.

Regarding the operation of reporting the direction information of the bicycle at regular time, the controller 310 may be configured to start the operation after successful unlocking in any use and end the operation after successful locking in the use; the controller 310 may also be configured to initiate the operation upon detection of the bicycle being parked in a designated parking area (also referred to as a parking fence, parking spot, etc.) after successful unlocking for any one of the uses, and to terminate the operation upon successful locking for the current use. For example, the bicycle may detect whether the bicycle has entered a designated parking area by establishing a connection with a bluetooth device or a radio frequency identification device provided in the parking area, and the like, which is not limited herein.

For another example, the server 100 may request the bicycle 300 to provide direction information after receiving the lock-off request, the bicycle 300 provides the latest posture data according to the request, and the server 100 determines the parking direction of the vehicle according to the posture data.

Based on this kind of control structure, through the direction of parking with the bicycle with the standard direction of parking corresponding to the parking position of bicycle is compared to when the two inconsistent suggestion user adjustment vehicle's the direction of parking, just can control the direction of parking of vehicle, so that the direction of parking of vehicle satisfies the requirement of parking of the parking position at this vehicle place, and then improve the regularity that the vehicle parked, this not only is favorable to improving city appearance, also is favorable to the user to get the car smoothly when using the car.

Based on such a control system structure of the bicycle 300, the following control method can be implemented, as shown in fig. 5, which may for example comprise the following steps:

in step S5210, the user terminal 200 issues an unlock request for the bicycle 300.

Step S5110, the server 100 responds to the unlocking request sent by the user terminal 200, performs relevant authentication, and sends an unlocking instruction to the bicycle 300 after the authentication is passed; and after the authentication fails, returning a message of the unlocking failure to the user terminal 200.

The related authentication includes user authentication, that is, whether a user account corresponding to the unlocking request meets a set condition is detected.

The set condition may be a condition indicating whether the user account is qualified to use the bicycle 300. The set conditions may include, for example: at least one of the deposit paid by the user, the arrearage not paid by the user and the balance of the account number of the user being more than or equal to the set minimum amount.

The related authentication may also include vehicle authentication, etc., and is not limited herein.

Step S5310, after receiving the unlocking instruction, the controller 310 of the bicycle 300 responds to the unlocking instruction to detect whether the bicycle meets a set unlocking condition, if so, controls the bicycle lock of the bicycle 300 to be unlocked, and reports an unlocking response indicating that the unlocking is successful to the server 100 after the unlocking is successful; if not, or after the unlocking failure, an unlocking response indicating the unlocking failure is reported to the server 100.

In step S5120, the server 100 performs a corresponding operation after receiving the unlocking response reported by the bicycle 300.

This step S5120 may include: when the unlocking response indicates that the unlocking is successful, the server 100 sets the bicycle 300 to be in the unlocking state, which indicates that a riding order is started; and when the unlocking response indicates that the unlocking fails, the unlocking operation is finished.

In step S5130, the server 100 transmits the unlock response to the user terminal 200.

In step S5220, the user terminal 200 performs a corresponding operation based on the unlock response.

The step S5220 may include: entering a riding interface when the unlocking response indicates successful unlocking; and when the unlocking response indicates that the unlocking is failed, the unlocking interface is exited.

In step S5230, the user terminal 200 issues a lock-off request for the bicycle 300.

Step S5140, the server 100 performs a related authentication in response to the locking request sent by the user terminal 200, and sends a locking instruction to the bicycle 300 after the related authentication is passed; and returning a message that the locking request fails to the user terminal 200 after the related authentication fails.

The related authentication may include detecting whether the riding order corresponding to the locking request meets a set condition, and the like.

The set condition may be a condition indicating validity of the lock-off request, and may include, for example: and the vehicle corresponding to the locking request is positioned in the appointed parking area, and the parking direction is consistent with the standard parking direction of the parking area where the vehicle is positioned.

In step S5140, the server 100 may first detect whether the bicycle 300 is parked in the designated parking area in response to the locking request, if not, the authentication fails, if so, continue to detect whether the parking direction of the bicycle is consistent with the standard parking direction of the parking area where the bicycle is located, otherwise, the authentication fails, and if so, confirm that the authentication is passed.

Step S5320, after receiving the lock-off command, the controller 310 of the bicycle 300 responds to the lock-off command to detect whether the bicycle meets a set lock-off condition, if so, controls the lock to lock off, and reports a lock-off response indicating that the lock is successfully locked off to the server 100 after the lock is successfully locked off; if not, whether the bicycle meets the locking condition is continuously detected.

The locking condition may include that a parameter value representing the current running speed of the bicycle 300 is less than or equal to a set safety threshold, or the like.

In step S5150, the server 100 finishes the current riding order to perform order settlement according to the lock closing response indicating that the lock closing is successful, and sends the result of the order settlement to the user terminal 200.

In step S5240, after receiving the result of order settlement, the user terminal 200 enters an order settlement interface for the user to perform order settlement.
