To enable those skilled in the art to use the present disclosure, the following embodiments are presented in conjunction with a specific application scenario "shared bicycle usage scenario". It will be apparent to those skilled in the art that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application.

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.
In order to enable a user to use a shared bicycle more conveniently, the shared bicycle can be kept in an unlocked state after legal use, when the next user needs to ride the shared bicycle, the user can be allowed to ride the shared bicycle by verifying the identity information legally without frequently switching on and off a locking process, but the process also brings certain disadvantages, namely, some illegal riding conditions can occur, namely, a bicycle-using request is not sent or the identity authentication is not passed, in such a case, the bicycle can be locked after the shared bicycle is detected to be illegally moved, but the situation can be caused by normal operation and maintenance or sudden change of environment of the shared bicycle, and the sudden forced locking can bring dangerous accidents to a rider, on the basis, the following technical scheme is provided in the embodiment of the application, and the vehicle resources and the vehicle-using safety of the user can be protected:
as shown in fig. 1, a vehicle lock control device 100 provided for an embodiment of the present application includes:
the main control circuit 101 is used for determining the moving speed of the vehicle when the vehicle is detected to be illegally moved in an unlocking state; when the moving speed is determined to be larger than zero and smaller than a set threshold value, the switch lock execution component is electrified, and the switch lock execution component is controlled to be switched off;
and the locking and unlocking execution unit 102 is used for executing locking and unlocking operations under the control of the main control circuit after being powered on.
Here, the main control circuit may refer to a circuit including a processor or a microcontroller, a power supply, and other elements and having a processing and control unit, and the main control circuit in this embodiment of the present application may be capable of communicating with a user terminal and controlling the unlocking and locking execution unit.
After receiving a returning instruction sent to the vehicle by the user side and determining that the moving speed of the vehicle is greater than zero and smaller than a set threshold value, the main control circuit energizes the unlocking and locking execution component of the vehicle, namely awakens the unlocking and locking execution component, so that the unlocking and locking execution component enters a working state from a dormant state.
The switch lock execution component provided by the embodiment of the application can comprise a brake lock circuit, and when the master control circuit powers on the brake lock circuit, the master control circuit enters a working state and can perform unlocking or locking operation.
In some embodiments of the present application, the master control circuit 101 may determine vehicle movement by the positioning device, as well as determine the speed of movement of the vehicle. The Positioning device may acquire the position information of the vehicle based on one or more Positioning technologies such as a Global Positioning System (GPS), a Global Navigation Satellite System (GLONASS), a COMPASS Navigation System (COMPASS), a galileo Positioning System, a Quasi-Zenith Satellite System (QZSS), Wireless Fidelity (WiFi), and Bluetooth (Bluetooth) Positioning. In some embodiments, the positioning device may be installed in the vehicle lock control device 100. In other embodiments, the locating device may be mounted elsewhere on the vehicle. The positioning device and the main control circuit can carry out signal transmission. The main control circuit can determine whether the vehicle moves according to the vehicle position information acquired by the positioning device. For example, the master control circuit may determine whether the vehicle has moved in position based on whether the vehicle location information has changed between two or more times. The master control circuit may also determine the speed of movement of the vehicle via the positioning device. For example, the master control circuit may determine the speed of movement of the vehicle based on the distance the vehicle position has moved between two or more times, or over a period of time.
In some alternative embodiments, the master control circuit 101 may also determine the movement and/or speed of movement of the vehicle using other means. For example, a wheel speed detection device (e.g., a hall sensor for detecting the rotation of a wheel) may be provided on the vehicle, and the wheel speed detection device may be connected to the main control circuit 101 and transmit a detected wheel speed signal to the main control circuit 101. The main control circuit may determine the moving speed of the vehicle from the wheel speed signal detected by the wheel speed detecting means.
After the main control circuit determines the moving speed of the vehicle, it may further determine whether the moving speed of the vehicle belongs to the above-mentioned interval, that is, whether the moving speed is greater than zero and less than a set threshold. The set threshold value may be a safety speed value determined in advance through a plurality of tests, and the wheel-moving rotating speed within the safety speed value does not cause injury to the rider even if the lock is suddenly closed, for example, the safety speed value may only be a speed value for pushing the vehicle to run, and if the determined moving speed is smaller than the safety speed value and larger than zero, it may be determined that the vehicle is illegally ridden, that is, the lock-opening executing component may be controlled to lock.
In the process of determining that the vehicle is illegally ridden, the specific flow chart is shown in fig. 2, when the main control circuit detects that the vehicle is illegally moved when the lock is in the unlocked state, the main control circuit can determine the moving speed of the vehicle through the positioning device. However, since the lock is in the unlocked state, the lock is generally not required to be changed in the on-off state, and the lock opening/closing execution part may be in the power-off state in order to save electric power consumption. Therefore, when the main control circuit determines that the moving speed of the vehicle is greater than zero and less than the set threshold, the switch lock execution unit is generally powered on, so that the switch lock execution unit enters a working state, and then the main control circuit controls the switch lock execution unit to switch lock. The locking and unlocking execution component executes locking and unlocking under the control of the main control circuit, and the vehicle cannot ride at the moment.
In the above process, the main control circuit detecting whether the vehicle is illegally moved may include: if the main control circuit detects that the vehicle is moved and does not receive the vehicle using request within the first set time period, the vehicle can be determined to be illegally moved.
In order to avoid the vehicle moving caused by the accidental vehicle dumping or normal operation and maintenance of the operation and maintenance personnel, whether the moving speed lasts for the second set time period or not (namely, the moving speed is greater than zero in the second set time period) can be detected, and if the moving speed is greater than zero, the vehicle is considered to be illegally ridden. For example, if the second set time period is 30 seconds, that is, if the moving speed of the vehicle lasting for 30 seconds is detected, it is determined that the vehicle is illegally ridden.
After the moving speed is determined to be greater than zero and less than the set threshold value, that is, the vehicle is illegally ridden, the main control circuit 101 is further configured to power off the switch lock execution unit 102 if information indicating that the vehicle lock is closed, which is sent by the switch lock execution unit, is received after the switch lock execution unit is controlled to be locked;
the unlocking and locking executing component 102 is further configured to send information indicating that the vehicle lock is closed to the main control circuit 101 when the vehicle is detected to be in a vehicle lock closing state after the unlocking and locking operation is performed.
The main control circuit determines that the vehicle is illegally ridden, the switch lock execution component can be controlled to lock by sending a lock closing instruction to the switch lock execution component, the switch lock execution component executes a lock closing operation after receiving the lock closing instruction sent by the main control circuit, detects whether the vehicle is closed or not after the lock closing operation is executed, and sends information indicating that the vehicle lock is closed to the main control circuit if the vehicle is detected to be in a vehicle lock closing state, wherein the information indicating that the vehicle lock is closed can be preset digital information, for example, "1" indicates that the vehicle lock is closed, and "0" indicates that the vehicle lock is not closed, and here, information "1" indicating that the vehicle lock is closed can be sent to the main control circuit.
When the main control circuit receives the information '1' indicating that the lock is closed, the lock opening and closing execution component is determined to close the lock, namely the illegal riding state of the vehicle is ended, the lock opening and closing execution component does not need to work again, and the power of the lock opening and closing execution component can be cut off in order to save power consumption.
The main control circuit 101 is further configured to, after receiving the information indicating that the lock is closed sent by the lock/unlock execution unit, report power failure information if the lock/unlock execution unit cannot be powered off within a third set time period.
Here, after the main control circuit controls the switch lock execution unit to switch on and off, if the switch lock execution unit cannot be powered off within a third set time, it is also determined that a power failure fault may occur, at this time, power failure fault information may be sent to a background server of the shared bicycle, and the power failure fault information here may carry an identification code and geographical location information of the vehicle, so that the background server is convenient for notifying related personnel to perform maintenance.
The main control circuit 101 is further configured to, after controlling the unlocking of the unlocking/locking execution unit 102, report an unlocking failure message if receiving a message indicating that the lock cannot be closed, which is sent by the unlocking/locking execution unit 102;
the unlocking and locking executing component 102 is further configured to send information indicating that the vehicle lock cannot be closed to the main control circuit 101 when detecting that the vehicle is still in an unlocked state after the unlocking operation is performed.
The method includes that a main control circuit controls a switch lock execution unit to be locked when a vehicle is determined to be in an illegal riding state, if information indicating that a vehicle lock cannot be closed is received, the switch lock execution unit is judged to possibly have a lock closing fault, the lock closing fault information can be sent to a background server, and the lock closing fault information can also include an identification code and position information of the vehicle.
Possible causes of the lock-off failure here include: the lock opening and closing execution part is damaged, and the lock cannot be closed; when the lock is damaged, the lock opening and closing execution part cannot close the lock; or the lock opening and closing executing component and the vehicle lock are damaged.
After the main control circuit detects that the vehicle is illegally moved, if the moving speed of the vehicle is determined to be greater than or equal to the set threshold value or zero, the unlocking and locking execution part is not operated.
Here, the main control circuit determines the moving speed of the vehicle by the positioning device after detecting that the vehicle is illegally moved. Considering that a positioning device (such as a GPS positioning device) has a certain accuracy error and may not accurately determine the moving speed of the vehicle in a short time, the main control circuit may determine whether there is a moving speed lasting for a second set time period, for example, 30 seconds, and if the moving speed lasting for the second set time period is not detected within 30 seconds, or the moving speed is not detected or the detected moving speed is zero, the moving speed is considered to be zero; or the moving speed lasting for the second set time length is detected, and the moving speed is greater than or equal to the set threshold value, the unlocking and locking execution component is not operated.
Specifically, when the main control circuit detects that the vehicle is illegally moved and the determined current moving speed of the vehicle is equal to 0, the following possible situations are:
legal movement caused by normal operation and maintenance or short-term displacement caused by environmental change, such as short-term displacement caused by a strong wind blowing down a vehicle, cannot be detected by the positioning device within 30 seconds, or the detected movement speed is zero. In the above case, the vehicle is not illegally ridden and does not need to be locked.
The method is characterized in that the current moving speed is determined to reach the safe speed value when the determined moving speed of the vehicle is larger than or equal to the set threshold value, and the vehicle is judged to be illegally ridden, so that the safety of a rider is protected to the maximum extent and the rider is not locked.
The overall flowchart of the above process, that is, the operation executed by the unlocking/locking execution component after the main control circuit determines that the vehicle has been illegally moved is shown in fig. 3, and the following description will be made with reference to fig. 3 by taking the shared bicycle 10010 as an example, and the above process is described as follows:
the main control circuit detects that the shared bicycle 10010 moves in an unlocked state through the positioning device, and when a bicycle using request is not received, it is determined that the shared bicycle 10010 is illegally moved, at this time, the main control circuit determines the moving speed of the shared bicycle 10010 within a second set time length through the positioning device, and if it is detected that the moving speed lasting the second set time length is greater than or equal to a set threshold (in an illegal riding state, but the riding speed exceeds a safe speed), or is equal to zero, the main control circuit does not operate the unlocking and locking execution component; if the locking and unlocking execution component is powered on and detects that the shared bicycle 10010 has a continuous moving speed lasting for a second set duration, and the moving speed is greater than zero and less than a set threshold value, it is determined that the shared bicycle 10010 is in an illegal riding state, and the riding speed value does not reach a safe speed value, at this time, the main control circuit is powered on for the locking and unlocking execution component and controls the locking and unlocking execution component to lock and unlock, then the locking and unlocking execution component performs locking and detects a bicycle lock state, when the locking and unlocking execution component detects that the bicycle lock is in a closed state, the locking and unlocking speed value is fed back to the main control circuit, at this time, the main control circuit powers off the locking and unlocking execution component to save power consumption, and if the main control circuit cannot power off the locking and unlocking execution component within a third set duration, power-off fault information can be; when the lock opening and closing execution component detects that the vehicle lock is in an unlocking state, the lock opening and closing execution component feeds back the lock opening and closing state to the main control circuit, and at the moment, the main control circuit determines that the lock opening and closing execution component has a lock closing fault and can also send lock closing fault information to the background server.
The above is a control process of the lock after it is determined that the lock is illegally moved, when it is detected that the vehicle is illegally moved, the moving speed of the vehicle needs to be detected again, it is determined that the vehicle is illegally ridden only when the moving speed of the vehicle is detected to be greater than 0 within the second set time duration, and it is determined that the moving speed is smaller than the set threshold value, that is, the moving speed does not reach the safety speed value, the lock is closed, if the current moving speed is 0 or reaches the safety speed value, the lock is not closed, so that in case that the vehicle is illegally ridden, it is possible to avoid that the lock is suddenly closed to hurt a rider, and in case that the vehicle is not illegally ridden, the lock is not closed to avoid the lock opening and closing of the lock execution component frequently, the service lives of the lock opening and closing execution component and the lock are prolonged, and it is also convenient for the next user.
Fig. 3 is a control flow chart of the vehicle lock after detecting that the vehicle is illegally moved, and the control flow of the vehicle lock will be described after receiving a vehicle using request sent by a user terminal.
The main control circuit 101 is further configured to energize the unlocking and locking execution unit 102 and issue an unlocking instruction when receiving a car use request sent by a user; after receiving the information indicating that the lock is currently in the unlocked state sent by the unlocking and locking execution component 102, verifying the user identity information carried in the vehicle using request, keeping the vehicle in the unlocked state after the verification is passed, and recording that the vehicle is in the legal riding state;
the lock opening and closing execution part 102 is further configured to detect an opening and closing state of the vehicle lock after receiving the unlocking instruction, and send information indicating that the vehicle lock is currently in the unlocking state to the main control circuit 101 if the vehicle lock is determined to be in the unlocking state; if the lock is determined to be in the locked state, after the lock is controlled to be unlocked, information indicating that the lock is in the unlocked state is sent to the main control circuit 101.
In the embodiment of the application, the master control circuit can directly receive the vehicle using request sent by the user side, the user side is not required to send the vehicle using request to the background server, the user side does not need to communicate with the background server in the vehicle using stage, the condition that the communication network fails and the identity authentication cannot be carried out is avoided, the user identity information is directly authenticated through the master control circuit, and the vehicle using authentication time is greatly shortened.
The main control circuit 101 is further configured to report unlocking fault information when receiving information indicating that the vehicle lock cannot be unlocked, which is sent by the unlocking and locking execution component 102, after the unlocking and locking execution component 102 is powered on and issues an unlocking instruction;
the lock opening and closing execution unit 102 is further configured to, if it is determined that the lock is in the lock closing state, detect that the lock is in the lock closing state after the unlocking operation is performed, and send information indicating that the lock cannot be opened to the main control circuit.
The main control circuit 101 is further configured to power off the switch lock execution unit after it is determined that the vehicle enters the legal riding state, and report power-off fault information if the switch lock execution unit 102 cannot be powered off within a third set time period.
As for the lock control process after receiving the car use request, as shown in fig. 4, the process is still described by taking the shared bicycle 10010 as an example:
after the master control circuit receives a vehicle using request, that is, when it is determined that a user wants to use the shared bicycle 10010, the lock opening and closing execution component is powered on and issues an unlocking instruction, after the lock opening and closing execution component receives the unlocking instruction, the on and off state of the lock is detected, if it is detected that the lock is in the unlocking state, information indicating that the lock is currently in the unlocking state is sent to the master control circuit, if it is determined that the lock is in the locking state, the lock is controlled to be opened, and after it is determined that the lock is opened, the information indicating that the lock is in the unlocking state is sent to the master control circuit, if it is determined that the lock is in the locking state, and after it is detected that the lock is still in the locking state, the information indicating that the lock cannot be opened is sent to the master control circuit, at this time, the master control circuit can send unlocking fault information of the shared bicycle 10010 to the background, the unlocking failure information may carry the identification code 10010 of the shared bicycle and the location information of the shared bicycle.
If the main control circuit receives information indicating that the lock is currently in the unlocked state sent by the unlocking and locking execution component, it is determined that the shared bicycle 10010 is in the riding state, and after it is determined that the shared bicycle 10010 is in the riding state, the user identity information carried in the bicycle using request is verified, for example, the user identity information may include whether the user is a registered user of the shared bicycle of the type and an account balance of the registered user, and if the user identity information is a registered user of the shared bicycle and the account balance corresponding to the registered user is greater than a set value, it is recorded that the bicycle is in the legal riding state, that is, the user can legally ride the shared bicycle 10010.
After the shared bicycle 10010 is in the legal riding state, that is, the user is in the normal riding process, the unlocking/locking execution component does not need to perform unlocking/locking operation, in order to save power consumption, the unlocking/locking execution component may be powered off, and if the unlocking/locking execution component cannot be powered off within a third set time period, for example, 15 seconds, the power-off fault may be reported to the background server.
The above process is a control process of the lock control device to the lock after receiving the vehicle using request of the user, and as will be described below, when the vehicle is in a legal riding state, after receiving a vehicle returning instruction sent by the user side to the vehicle, an executed process is as follows:
the main control circuit 101 is further configured to determine the moving speed of the vehicle through the positioning device when receiving a vehicle returning instruction sent by the user side to the vehicle, and record that the vehicle returning of the user is successful if the moving speed of the vehicle is zero. After the recording user returns the car successfully, in order to make the next user ride, keep the car in the state of unblanking.
The main control circuit 101 is further configured to record that the vehicle is in a riding state and keep the vehicle in an unlocking state if the moving speed of the vehicle determined by the positioning device is not zero (i.e., has a moving speed) after receiving a vehicle returning instruction sent to the vehicle by the user side.
In this case, although the main control circuit receives the returning instruction, the positioning device determines that the vehicle still has the moving speed, and it is determined that the situation may be that the user is still in the riding state, and only the returning key on the user side is triggered by mistake, and at this time, the vehicle is recorded as the riding state, and the success of returning the vehicle by the user is not recorded.
After the main control circuit receives the returning instruction, it can be divided into two different processing procedures by determining whether the vehicle has a moving speed, and a flowchart thereof is shown in fig. 5, taking the vehicle as a sharing bicycle as an example, the process will be explained by the following specific embodiments:
after receiving the returning command sent by the user a, the main control circuit of the lock control device on the shared bicycle numbered 10010 determines the moving speed of the shared bicycle 10010 through the positioning device on the shared bicycle 10010, and if it is determined that the shared bicycle 10010 has no moving speed, the main control circuit records that the returning of the shared bicycle is successful, and the shared bicycle 10010 is kept in the unlocking state; if it is determined that the shared bicycle 10010 has a moving speed, the main control circuit records that the shared bicycle 10010 is in the riding state, and similarly keeps the shared bicycle in the unlocking state.
According to the embodiment of the application, after the main control circuit receives the car returning instruction, whether the car has the moving speed or not is determined through the positioning device, after the fact that the moving speed does not exist is determined, the car returning success is recorded, the accuracy of determining whether the user returns the car or not is improved, and the situation that dangerous events occur to the user caused by sudden car locking after the user is mistakenly judged to return the car is avoided.
