Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
With the popularization of smart automobiles, bluetooth is widely applied to the field of automobiles as a novel smart non-inductive key. The user sends out bluetooth control signal through the car key, obtains one or more bluetooth signal intensity through the cell-phone, then judges the current state of locking or unblock according to the algorithm. Because bluetooth radio frequency equipment all installs on metal device, in addition the bluetooth signal receives the interference of factors such as the position at car casing, user place, interference signal around the car, bluetooth signal characteristics, signal of telecommunication easily, when passing through bluetooth signal control door, produces the maloperation easily, for example, owing to receive external disturbance, the bluetooth signal jumps repeatedly easily, leads to the door to unblank repeatedly and close.
For another example, inside the vehicle body, due to the influence of the vehicle shell, the separation degree of external signals is relatively low, general errors can go to more than plus or minus 3 meters, and in addition, the mobile phone of the user may interfere with the bluetooth signal differently at different parts of the user, so that the bluetooth signals in the locked area and the unlocked area are seriously overlapped, the situation of frequent unlocking may be caused, and even actions such as a rearview mirror and a door handle are triggered, so that the user experience is extremely poor.
In some interference situations, please refer to fig. 1, the horizontal axis represents time, the vertical axis represents signal strength, the curve L1 is a waveform curve of the bluetooth signal acquired by the vehicle when the bluetooth key of the user is 4 meters away from the vehicle, and the curve L2 is a waveform curve of the bluetooth signal acquired by the vehicle when the bluetooth key of the user is 10 meters away from the vehicle. At a distance of 4 meters from the automobile, due to various interference factors, between 61 seconds and 94 seconds, the curve L2 is already superimposed with the curve L1, namely, the curve L1 overlaps with the signal in the curve L2, and for the convenience of viewing, a dashed box is shown in the figure, namely, the curve L1 also contains a signal of-82 dbm.
In view of the above technical problems, the inventors have found and proposed a door lock control method, device, automobile and storage medium through long-term research, and obtain a door lock control signal corresponding to a current time as a first door lock control signal, and obtain a plurality of door lock control signals at a preset time interval before the current time as a second door lock control signal, when the first door lock control signal is the same as the second door lock control signal, the door lock is controlled by the first door lock control signal, and after the door lock control signal for controlling the door lock is stable at the current time after the preset time interval, the door lock is controlled by the door lock control signal, so that accurate control of a door state is ensured, and misoperation is prevented.
Fig. 2 is a schematic flow chart of a door lock control method according to an embodiment of the present application, where after a door lock control signal is stable, the door lock is controlled by the door lock control signal to ensure accurate control of the door lock and prevent misoperation. In the specific embodiment, the door lock control method is applied to the door lock control device 100 shown in fig. 7 and the automobile 200 (fig. 8) equipped with the door lock control device 100. The present embodiment will explain a specific flow of the present embodiment by taking an example in which the door lock control method is applied to an automobile. As will be described in detail with respect to the flow shown in fig. 2, the door lock control method may specifically include the following steps:
step S110, acquiring a door lock control signal corresponding to the current time as a first door lock control signal, and acquiring a plurality of door lock control signals within a preset time interval before the current time as a second door lock control signal.
The automobile acquires a door lock control signal generated by the unlocking device at the current moment, and the door lock control signal is used as a first door lock control signal which is used for indicating and controlling the door lock to be in an unlocking state or a locking state.
Optionally, when the door lock control method is applied to an automobile, the first door lock control signal may be a bluetooth signal, and the door lock device may be a car key matched with the automobile of the user, or may be a mobile terminal connected to the automobile, such as a mobile phone, a tablet computer, a wearable device, and the like of the user. When the first door lock control signal is a bluetooth signal, the acquired bluetooth signal may be generated by a plurality of devices, and a bluetooth signal corresponding to the unlocking device is determined from the plurality of bluetooth signals as a target bluetooth signal according to an identifier of the unlocking device, for example, a medium access control address (mac), that is, the target bluetooth signal is used as the first door lock control signal.
Optionally, when the door lock control method is applied to an access control system, the first door lock control signal may also be a radio frequency signal.
And the automobile acquires a plurality of corresponding door lock control signals in a preset time interval from the historical time to the current time as second door lock control signals. Alternatively, the preset time interval may be 3 seconds, 4 seconds, etc., and is not limited herein. For example, when the preset time interval is 3 seconds, the current time is 9 points, zero 3 minutes and zero 5 seconds, the historical time is a time corresponding to 3 seconds before the current time, that is, the historical time is 9 points, zero 3 minutes and zero 2 seconds, and a plurality of door lock control signals between 9 points, zero 3 minutes and zero 2 seconds and 9 points, zero 3 minutes and zero 5 seconds are acquired.
Optionally, when a plurality of door lock control signals between the historical time and the current time are collected, the door lock control signals may be collected according to a preset sampling frequency. For example, the preset sampling frequency may be acquired 1 time per second or 2 times per second, and the preset sampling frequency may be adjusted according to the control sensitivity, which is not limited herein, and optionally, the higher the sensitivity is, the higher the corresponding preset sampling frequency is, the lower the sensitivity is, and the lower the corresponding preset sampling frequency is.
The door lock control signal comprises an unlocking control signal and a locking control signal, wherein the unlocking control signal is used for indicating the unlocking of the door lock, and the locking control signal is used for indicating the locking of the door lock. When the door lock control signal is an unlocking control signal, acquiring the unlocking control signal corresponding to the current moment as a first unlocking control signal, and acquiring a plurality of unlocking control signals within a first preset time interval before the current moment; and when the door lock control signal is a locking control signal, acquiring the locking control signal corresponding to the current moment as a first locking control signal, and acquiring a plurality of locking control signals in a second preset time interval before the current moment.
In some embodiments, the corresponding sensitivities may be different when unlocking and locking the door lock. For example, the corresponding sensitivity during unlocking is higher than the corresponding sensitivity during locking, that is, the first preset time interval is smaller than the second preset time interval, so that the user can be ensured to quickly unlock the vehicle before using the vehicle, and the user can be ensured to lock the vehicle door after using the vehicle. Or the sensitivity corresponding to unlocking is lower than the sensitivity corresponding to locking, namely the first preset time interval is greater than the second preset time interval.
In other embodiments, the sensitivity of the unlocking and locking of the door lock is the same, i.e. the first predetermined time interval is equal to the second predetermined time interval, ensuring accurate unlocking and locking.
In order to determine whether the door lock control signal is stable, it is determined whether the first door lock control signal is the same as the second door lock control signal. When the first door lock signal is different from the second door lock signal, it is indicated that the door lock signal may be unstable due to an interference factor in a preset time interval from a historical time to a current time, and therefore, the first door lock control signal does not need to be responded, that is, the door lock is kept in a current unlocking or locking state.
And step S120, when the first door lock control signal is the same as the second door lock control signal, controlling the door lock through the first door lock control signal.
When the first door lock control signal is the same as the second door lock control signal, the door control lock signal is stable, and the door lock can be controlled through the first door lock control signal. Because the door lock control signal is relatively stable, the door lock control signal changes less in a preset time interval from the historical moment to the current moment, and any door lock control signal in the preset time interval, namely the second door lock control signal, can be used for controlling the door lock.
In one embodiment, the door lock state may be controlled by unlocking or locking as indicated by the first door lock control signal.
In other embodiments, the unlocking or locking of the door lock may be controlled according to the signal strength of the first door lock control signal. Specifically, when the signal intensity of the first door lock control signal is within the unlocking interval, the first door lock control signal controls the door lock to unlock, namely, the lock ring of the door lock is unlocked; or, when the signal intensity of the first door lock control signal is within the locking interval, the first door lock control signal controls the door lock to lock, namely, the lock ring of the door lock is closed.
In the door lock control method provided in this embodiment, a door lock control signal corresponding to the current time is obtained as a first door lock control signal, and a plurality of door lock control signals at a preset time interval (i.e., between the historical time and the current time) before the current time are obtained as second door lock control signals.
Optionally, the present embodiment provides a door lock control method based on the above embodiment, for controlling unlocking of the door lock, fig. 3 shows a schematic flow chart of the door lock control method provided in another embodiment of the present application, please refer to fig. 3, where the door lock control method specifically includes the following steps:
step S210, acquiring a door lock control signal corresponding to the current time as a first door lock control signal, and acquiring a plurality of door lock control signals within a preset time interval before the current time as second door lock control signals.
For details of step S210, please refer to step S110, which is not repeated herein.
Step S220, a plurality of door lock states corresponding to a preset time period are obtained, wherein the door lock states comprise an unlocking state and a locking state.
The preset time period includes the current time, and the plurality of door lock states corresponding to the preset time period are acquired, optionally, the preset time period may be 1 second, for example, the preset time period is a time period between 9 o 'clock and 1 minute 1 second and 9 o' clock and 1 minute 2 seconds.
In some embodiments, a plurality of signal intensities corresponding to a preset time period are obtained, and a plurality of door lock states corresponding to the plurality of signal intensities are obtained through a preset algorithm. Alternatively, the plurality of door lock states corresponding to the plurality of signal strengths may be recognized and recognized by a recognition model trained in advance.

The signal strength of the plurality of signal strengths that is not in the unlock interval or the lock interval corresponds to an irrelevant state, and it is understood that the irrelevant state may be an interference signal.
For example, the plurality of signal strengths includes-73 dbm, -70dbm, -68dbm, -95dbm, and-130 dbm. The unlocking interval is between-75 dbm and-65 dbm, and the locking interval is between-100 dbm and-85 dbm. 73dbm, -70dbm and-68 dbm are all in an unlocking interval [ -75dbm, -65dbm ], and 3 correspond to an unlocking state; -95dbm is in a latching range [ -100dbm, -85dbm ], in a latched state; 130dbm is not in the unlocking interval (-75 dbm, -65 dbm) and the locking interval (-100 dbm, -85 dbm), is in the irrelevant state.
And step S230, calculating the probability of the unlocking state in the plurality of door lock states to obtain the unlocking probability.
The unlocking probability is calculated by dividing the unlocking state by the plurality of door lock states, and continuing with the above example, if the unlocking states are 3 and the total number of states is 5, the calculated unlocking probability is 3/5 × 100% =60%.
Or, the probability of the locked state in the plurality of door lock states is calculated to obtain the locked probability, and with continuing the above example, if the number of locked states is 1 and the total number of locked states is 5, the calculated locked probability is 1/5 × 100% =20%.
And step S240, when the unlocking probability is greater than a preset probability, determining that the door lock state indicated by the first door lock control signal corresponding to the current moment is the unlocking state.
Optionally, when the calculated unlocking probability is the preset unlocking probability, the preset probability may be the preset unlocking probability, and the preset unlocking probability may be set according to actual conditions, for example, the preset unlocking probability may be 59%, 60%, 80%, and the like. Taking the preset unlocking probability as 59% as an example, when the unlocking probability is 60%, the unlocking probability is 60% greater than the preset unlocking probability 59%, and the door lock state indicated by the first door lock control signal corresponding to the current moment is determined to be the unlocking state.
Alternatively, when the lockout probability is calculated, the preset probability may be a preset lockout probability, and the preset lockout probability may be set according to actual conditions, for example, the preset lockout probability may be 59%, 60%, 80%, or the like. Taking the preset locking probability as an example, and when the locking probability is 20%, and the locking probability is 20% and is less than the preset locking probability 59%, it is determined that the door lock state indicated by the first door lock control signal corresponding to the current time is not the locked state, but is the unlocked state.
And S250, when the first door lock control signal is the same as the second door lock control signal, controlling the door lock to be unlocked through the unlocking state indicated by the first door lock control signal.
In this embodiment, a plurality of door lock states corresponding to the preset time period are obtained, and among the plurality of door lock states, a state with a large proportion can represent a state at the current time, so that the accuracy of the state obtained at the current time is ensured, and the accuracy of door lock control is improved.
Optionally, the present embodiment provides a door lock control method based on the above embodiment, for controlling locking of the door lock, fig. 4 shows a schematic flow chart of a door lock control method according to another embodiment of the present application, please refer to fig. 4, where the door lock control method may specifically include the following steps:

In some embodiments, a plurality of signal intensities corresponding to the preset time period are obtained, and a plurality of door lock states corresponding to the plurality of signal intensities are obtained through a preset algorithm. Alternatively, the plurality of door lock states corresponding to the plurality of signal strengths may be recognized and recognized by a recognition model trained in advance.
In other embodiments, the unlocking interval and the locking interval are preset, a plurality of signal strengths corresponding to the preset time period are obtained, the signal strength in the unlocking interval in the plurality of signal strengths corresponds to the unlocking state, and the signal strength in the locking interval in the plurality of signal strengths corresponds to the locking state. The signal strength of the plurality of signal strengths that is not in the unlock interval or the lock interval corresponds to an irrelevant state, and it is understood that the irrelevant state may be an interference signal.
For example, the plurality of signal strengths includes-73 dbm, -90dbm, -88dbm, -95dbm, and-100 dbm. The unlocking interval is between-75 dbm and-65 dbm, and the locking interval is between-100 dbm and-85 dbm. -90dbm, -88dbm, -95dbm and-100 dbm are all in a latching interval [ -100dbm, -85dbm ], 4 are corresponding to latching states; -73dbm is in the locking interval [ -100dbm, -85dbm ], in the unlocked state.
And step S330, calculating the probability of the unlocking state in the plurality of door lock states to obtain the unlocking probability.
The unlocking probability is calculated by dividing the unlocking state by the plurality of door lock states, and with continuing the above example, if there are 1 unlocking state and 5 unlocking states in total, the calculated unlocking probability is 1/5 × 100% =20%.
Or, the probability of the locked state in the plurality of door lock states is calculated to obtain the locked probability, and if the number of locked states is 4 and the total number of locked states is 5 with continuing the above example, the calculated locked probability is 4/5 × 100% =80%.
And step S340, when the unlocking probability is smaller than the preset probability, determining that the door lock state indicated by the first door lock control signal corresponding to the current moment is a locking state.
Optionally, when the calculated unlocking probability is a preset unlocking probability, the preset probability may be a preset unlocking probability, and the preset unlocking probability may be set according to an actual situation, for example, the preset unlocking probability may be 60%, 80%, or the like. Taking the preset unlocking probability as 60%, when the unlocking probability is 20%, the unlocking probability is 20% and is less than 60%, and it is determined that the door lock state indicated by the first door lock control signal corresponding to the current time is not the unlocking state but the locking state.
Optionally, when the locking probability is calculated, the preset probability may be a preset locking probability, and the preset locking probability may be set according to an actual situation, for example, the preset locking probability may be 60%, 80%, or the like. Taking the preset locking probability as 60% as an example, and when the locking probability is 80%, if the locking probability is 80% and is greater than the preset locking probability 60%, determining the door lock state locking state indicated by the first door lock control signal corresponding to the current moment.
And S350, when the first door lock control signal is the same as the second door lock control signal, controlling the door lock to be locked through the locking state indicated by the first door lock control signal.
In this embodiment, a plurality of door lock states corresponding to the preset time period are obtained, and among the plurality of door lock states, a state with a large proportion can represent a state at the current time, so that the accuracy of the state obtained at the current time is ensured, and the accuracy of door lock control is improved.
Optionally, when the door lock is controlled, after the automobile is successfully connected with the unlocking device, the automobile receives a door lock control signal for the first time as a primary door lock control signal, and when the primary door lock control signal is a primary unlocking control signal, the automobile controls the door lock to be unlocked through the primary unlocking control signal; when the primary lock control signal is a primary lock signal, the received signals are all lock control signals within a third preset time interval after the primary lock signal is received, and the vehicle door is controlled to be locked, wherein the third preset time interval can be 3 seconds, for example.
Fig. 5 shows a schematic flow diagram of a door lock control method according to still another embodiment of the present application, please refer to fig. 5, where the door lock control method specifically includes the following steps:

And acquiring the current door lock state, wherein the current door lock state is a locking state or an unlocking state. And acquiring a target door lock state indicated by the first door lock control signal, wherein the target door lock state is a locking state or an unlocking state. And judging whether the current door lock state is the same as the target door lock state, and when the current door lock state is different from the target door lock state, namely the current door lock state is a locked state and the target door lock state is an unlocked state, or the current door lock state is an unlocked state and the target door lock state is a locked state, indicating that the door lock control signal is unstable, and controlling the door lock to keep the current door lock state.

In this embodiment, when the current door lock state is different from the target door lock state, the door lock state is switched from the current door lock state to the target door lock state, so as to ensure timely adjustment of the door lock state.
On the basis of the above embodiments, the present embodiment provides a door lock control method, which controls door lock information in combination with signal strength on the basis of a door lock control signal. Fig. 6 is a schematic flow chart of a door lock control method according to yet another embodiment of the present application, and referring to fig. 6, the door lock control method may specifically include the following steps:

And S520, when the first door lock control signal is the same as the second door lock control signal, controlling the door lock through the first door lock control signal.
For the detailed description of steps S510 to S520, refer to steps S110 to S120, which are not described herein again.
Step S530, when the first door lock control signal is different from the second door lock control signal, acquiring the signal intensity of the first door lock control signal as a first signal intensity.
When the first door lock control signal is different from the second door lock control signal, the signals are unstable, and the door lock cannot be controlled by the door lock control signal within the preset time interval. The signal strength of the first door lock control signal is acquired as the first signal strength, which may be-100 dbm, for example.
And step S540, acquiring a time of the previous switching of the door lock state at the current time as a history time, and acquiring a signal intensity of the door lock control signal corresponding to the history time as a second signal intensity.
The time corresponding to the last state switching is taken as the historical time, and it can be understood that, in the present embodiment, the signal strength of the door lock control signal corresponding to the historical time is taken as the second signal strength instead of the initial adjustment of the door lock state, and the second signal strength may be-90 dbm, for example.

Combining the above examples, the signal strength difference is (-90 dbm) - (-100 dbm) =10dbm.
And step S560, when the signal intensity difference is greater than a preset intensity difference, controlling the door lock through the first door lock control signal.
For example, if the preset intensity difference is 5dbm and the preset intensity difference 10dbm is greater than the preset intensity difference 5dbm, the door lock is controlled by the first door lock control signal.
