Based on the above structure of the control system of the electric bicycle 300, the following control method may be implemented, as shown in fig. 5, and may include, for example, the steps of:
in step S5210, the user terminal 200 issues an unlock request for the electric 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 electric 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 the user account corresponding to the unlocking request meets the second unlocking condition is detected.
The second unlocking condition may be a condition indicating whether the user account is qualified to use the electric bicycle 300. The second unlocking condition 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, that is, detecting whether the electric bicycle satisfies at least a part of the first unlocking condition, and the like. In another control method, the vehicle authentication may be omitted in step S5110.
The first unlocking condition may be a condition indicating whether the electric bicycle 300 has a normal traveling capability. For example, the first unlocking condition may include: the remaining capacity of the electric bicycle is greater than or equal to at least one of the set capacity threshold, the assist motor 382 is in a normal state without a failure, and the output voltage of the twist grip is in a normal range.
Step S5310, after receiving the unlocking instruction, the first controller 311 of the electric bicycle 300 sends the unlocking instruction to the second controller 312, and the second controller 312 detects whether the electric bicycle meets the first unlocking condition in response to the unlocking instruction, if so, controls the unlocking of the lock of the electric bicycle 300, and after the unlocking is successful, notifies the first controller 311 to report an unlocking response indicating that the unlocking is successful to the server 100; if not, or after the unlocking failure, the first controller 311 is notified to report an unlocking response indicating the unlocking failure to the server 100.
In step S5320, the second controller 312 of the electric bicycle 300 detects a parameter value of the current running speed of the electric bicycle 300 after the unlocking is successful, and controls the assist motor 382 to provide the assist force if the parameter value is greater than or equal to the start threshold.
The parameter value may be, for example, a speed value, a stator voltage value of the assist motor 382, or a tread frequency value, etc., and is not limited herein.
In step S5120, the server 100 performs a corresponding operation after receiving the unlocking response reported by the electric bicycle 300.
This step S5120 may include: when the unlocking response indicates that the unlocking is successful, the server 100 sets the electric 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 electric 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 electric 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 second locking condition, and the like.
The second lock-off condition may be a condition indicating validity of the lock-off request. The second lock-off condition may include, for example: the riding order corresponding to the locking request is valid, the user corresponding to the locking request stops riding the electric bicycle, the electric bicycle corresponding to the locking request is located in the parking fence, and the electric bicycle corresponding to the locking request is located in at least one of the designated parking positions.
Step S5330, after receiving the lock-off instruction, the first controller 311 of the electric bicycle 300 sends the lock-off instruction to the second controller 312, and the second controller 312 detects whether the electric bicycle meets the first lock-off condition in response to the lock-off instruction, and if so, controls the lock-off of the bicycle, and notifies the first controller 311 to report a lock-off response indicating that the lock-off is successful to the server 100 after the lock-off is successful; if not, whether the electric bicycle meets the first locking condition or not is continuously detected.
The first locking condition may include that a parameter value representing the current running speed of the electric bicycle 300 is less than or equal to a set safety threshold.
In step S5150, the server 1000 ends 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.
In the control system of the electric bicycle of the embodiment, two controllers are provided, the electric bicycle 300 performs information interaction with the server 100 through the first controller 311 to perform overall control of the electric bicycle 300 through the first controller 311, and performs control of the assist motor 382 and the lock motor 381 through the second controller 312, thereby separating at least partial power control from overall control, so that when a problem occurs in one of the controllers 311 or 312, the other controller 312 or 311 can still perform related processing for handling the fault, which is beneficial to improving the use safety of the electric bicycle.
In one embodiment, the interface module 330, the output module 350, and the input module 340 of fig. 1 may be connected with the first controller 311 to enable the first controller 311 to perform overall control of the electric bicycle 300, etc. through the modules.

Fig. 3 is a block schematic diagram of a control system of an electric bicycle according to another embodiment. As shown in fig. 3, the control system of the present embodiment further includes a battery lock motor 383 on the basis of the structure shown in fig. 2.
In this embodiment, the electric bicycle 300 is provided with a battery lock for the battery module 3120 as shown in fig. 4. When the battery lock is in the off-lock state, the battery module 3120 can be locked on the body of the electric bicycle 300, and the battery module 3120 is prevented from being stolen. When the battery lock is in the unlocked state, the operator can take down the battery module 3120 to replace the battery module 3120.
The battery lock includes a battery lock motor 383 and a battery lock mechanism. The battery lock motor 383 is used for driving the battery lock mechanism to act.
In this embodiment, the battery lock motor 383 is connected to the first controller 311 to drive the battery lock mechanism to operate according to the control of the first controller 311, so as to unlock and lock the battery lock.
In this embodiment, the battery lock is controlled to perform the unlocking and locking actions mainly in a situation where an operator replaces a battery module, and at this time, the electric bicycle 300 does not need to be in a state of being available for use, so that the battery lock motor 383 is controlled to act through the first controller 311, and the second controller 312 does not need to be waken up when the battery module 3120 is replaced, thereby saving energy consumption.
In further embodiments, the battery lock motor 383 can also be coupled to the second controller 312 such that the second controller 312 becomes a motor controller dedicated to controlling the various motors.
