Detailed Description
So that the manner in which the features and elements of the present embodiments can be understood in detail, a more particular description of the embodiments, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
The technical scheme of the embodiment of the application can be applied to various terminals, such as mobile phones, tablet computers, wearable devices, notebooks and the like. The terminal of the embodiment of the application can unlock the vehicle, wherein the type of the vehicle is not limited, and the vehicle can be a bicycle, a scooter, a balance car, an automobile and the like. As shown in fig. 1, the communication between the vehicle and the terminal may be via bluetooth. Wherein, in order to realize bluetooth communication, need to set up first bluetooth module on the terminal, need set up second bluetooth module on the vehicle. The terminal can realize the communication with the second Bluetooth module on the vehicle through the first Bluetooth module. Fig. 1 illustrates one-to-one communication (i.e., one terminal communicates with one vehicle) as an example, but is not limited thereto, and one terminal may communicate with a plurality of vehicles at the same time.
Fig. 2 is a first schematic flow chart of a vehicle unlocking method provided in an embodiment of the present application, where the vehicle unlocking method is applied to a terminal, the terminal has a first bluetooth module, and the terminal can establish a communication connection with a second bluetooth module of a vehicle through the first bluetooth module, as shown in fig. 2, the vehicle unlocking method according to the embodiment of the present application includes:
step 201: and after the unlocking operation is obtained, the RSSI value of the second Bluetooth module is detected by utilizing the first Bluetooth module.
In the embodiment of the application, after the terminal obtains the unlocking operation, the RSSI value of the second Bluetooth module of the vehicle is detected by using the first Bluetooth module. In practical application, a starting switch can be arranged on the vehicle, and when a user wants to unlock the vehicle, the unlocking operation information can be sent to the terminal by touching the starting switch. It should be noted that the terminal may be a mobile phone, a tablet computer, or a wearable device. The terminal is provided with a first Bluetooth module and can establish communication connection with a second Bluetooth module of the vehicle through the first Bluetooth module so as to realize vehicle unlocking through a Bluetooth technology.
In the embodiment of the application, after the terminal establishes communication connection with the second bluetooth module of the vehicle through the first bluetooth module, the RSSI value of the second bluetooth module can be detected. Here, the second bluetooth module of the vehicle may transmit a bluetooth signal in a unicast manner or a broadcast manner, and the first bluetooth module of the terminal detects a signal strength value of the bluetooth signal, wherein the signal strength value of the bluetooth signal may be characterized by an RSSI value. It should be noted that, in the embodiment of the present application, the signal strength value of the bluetooth signal sent by the second bluetooth module, which is detected by the first bluetooth module, is referred to as the RSSI value of the second bluetooth module.
Step 202: comparing the RSSI value with an unlocking threshold value, and if the RSSI value is greater than or equal to the unlocking threshold value, sending an unlocking instruction to the second Bluetooth module; the unlocking instruction is used for unlocking the vehicle, and the unlocking threshold value is determined according to the number of RSSI data.
In general, the closer the distance between the bluetooth module and the terminal is, the larger the RSSI value is, so that the positional relationship between the terminal and the vehicle can be determined from the RSSI value. However, since the RSSI value of the bluetooth module is greatly affected by the distance and the obstacle, even if the same terminal and vehicle are located at the same position for bluetooth connection, the RSSI value is affected by the position of the terminal (for example, the user holds the terminal in his hand, puts the terminal in a bag, or in a pocket). Therefore, the same terminal and the same vehicle are in equidistant positions, and when the bluetooth connection is performed for multiple times, the RSSI value fluctuates within a certain range due to different positions where the terminals are placed, so that a fixed unlocking threshold value may be difficult to adapt to different unlocking scenes.
In the embodiment of the application, the terminal acquires the number of local RSSI data stored locally and judges whether the number of the local RSSI data is greater than or equal to a number threshold value or not; if the number of the local RSSI data is larger than or equal to the number threshold, setting an experience threshold as the unlocking threshold; and if the number of the local RSSI data is smaller than the number threshold, setting a default threshold as the unlocking threshold. The empirical threshold may be calculated according to the local RSSI data, or determined according to a data value distribution of the local RSSI data; or the terminal receives the experience threshold value which is sent by the cloud and updated based on the data value distribution condition of the historical RSSI data. The default threshold is the default threshold after the terminal receives the data value distribution condition which is sent by the cloud and is updated based on the historical RSSI data. It should be noted that the default threshold may be obtained based on test data of the worker, for example, the default threshold may be a threshold preset at the terminal and the cloud based on a large number of manual tests performed by the worker in the early stage. The default threshold may also be a threshold calculated based on previous manual test data of a worker and historical RSSI data of the cloud when the amount of historical RSSI data of the cloud is not enough to calculate the empirical threshold. The experience threshold is divided into a local calculated experience threshold and a cloud calculated experience threshold, the local calculated experience threshold may be calculated by the terminal according to local RSSI data, and the cloud calculated experience threshold may be obtained by the cloud according to actual use data of other users, for example, the cloud calculated experience threshold may be calculated by historical RSSI data of other users during actual use. The local RSSI data are local historical unlocking RSSI data of the terminal used by the user, and the historical RSSI data of the cloud are historical unlocking RSSI data of all terminals and vehicles which are stored on the cloud and have the same model as the terminal and vehicle used by the user.
In the embodiment of the application, the unlocking threshold is determined according to the number of the RSSI data, when the number of the local RSSI data stored locally reaches the number threshold, the terminal determines an experience threshold according to the data value distribution condition of the local RSSI data, and the experience threshold is used as the unlocking threshold; when the number of the local RSSI data stored locally does not reach the number threshold, the terminal requests the cloud to obtain the updated experience threshold, that is, when the number of the local RSSI data is insufficient, the experience threshold determined based on the data value distribution condition of the historical RSSI data of the cloud is used as the unlocking threshold. Furthermore, when the number of the historical RSSI data in the cloud does not reach the number threshold, the terminal enables a default threshold as an unlocking threshold. It should be noted that the local RSSI data stored locally are historical unlocking data of the terminal itself, that is, the local RSSI data stored locally is the data most related to the unlocking state and rule of the terminal, the experience threshold determined based on the data value distribution condition of the local RSSI data stored locally is the most capable of representing the unlocking state and rule of the terminal, and the unlocking operation is performed based on the experience threshold determined based on the data value distribution condition of the local RSSI data, so that the unlocking accuracy can be ensured to a great extent, and the unlocking success rate can be greatly improved. For example, if the number threshold is 100, and the number of the local RSSI data is greater than or equal to 100, the terminal may determine an empirical threshold according to a data value distribution of the local RSSI data, and if the distribution of the 100 local RSSI data is: 80% of the RSSI data are distributed below the unlocking threshold, and only 20% of the RSSI data are distributed above the unlocking threshold, so that the unlocking success rate of the terminal is very low (the reason for this may be that the RSSI data of the terminal is lower than the RSSI data of the same type of terminal, or the RSSI data of the terminal is lower due to the hardware aging of the terminal, or the RSSI data of the terminal is lower due to the use habit of the user), and the terminal adjusts the unlocking threshold based on the distribution condition of the 100 pieces of local RSSI data, and lowers the unlocking threshold (it should be noted that the adjustment may also be to recalculate the unlocking threshold in a preset calculation manner), so that the unlocking threshold is more adapted to the RSSI data of the terminal, thereby improving the unlocking success rate and improving the user experience. The experience threshold value updated by the cloud end is determined according to the data value distribution condition of the RSSI data which is the same as the terminal type in the historical RSSI data of the cloud end and is the same as the unlocking vehicle type, although the historical RSSI data of the cloud end which is the same as the terminal type and is the unlocking vehicle type is selected, compared with the historical unlocking data of the terminal, the historical unlocking data of the cloud end is only the data which is secondarily related to the terminal, compared with the default threshold value which is preset in the terminal and the cloud end by workers through a large number of manual tests in the early period and is based on the data of the manual tests, the experience threshold value determined according to the data value distribution condition of the historical RSSI data of the cloud end is wider in data and more in covered scenes, therefore, the unlocking operation is performed according to the experience threshold value determined according to the data value distribution condition of the historical RSSI data of the cloud end, and the unlocking accuracy rate can be ensured to a great extent, and greatly improves the unlocking success rate. It should be noted that the determination process of the experience threshold at the cloud end is similar to the determination process of the local experience threshold, and is not described herein again. Different unlocking thresholds are dynamically selected in the embodiment of the application, and the unlocking thresholds are continuously updated and optimized based on historical unlocking data, so that the unlocking success rate is continuously improved.
It should be noted that the historical RSSI data in the cloud may be a collection of RSSI data uploaded by each terminal.
In the embodiment of the application, the terminal compares the RSSI value with an unlocking threshold value, and if the RSSI value is greater than or equal to the unlocking threshold value, an unlocking instruction is sent to the second Bluetooth module; the unlocking instruction is used for unlocking the vehicle. Different unlocking thresholds are dynamically selected in the embodiment of the application, and the unlocking thresholds are continuously updated and optimized based on historical unlocking data, so that the unlocking success rate is continuously improved.
Fig. 3 is a second flowchart of a vehicle unlocking method provided in an embodiment of the present application, where the vehicle unlocking method is applied to a terminal, the terminal has a first bluetooth module, and the terminal can establish a communication connection with a second bluetooth module of a vehicle through the first bluetooth module, as shown in fig. 3, the vehicle unlocking method according to the embodiment of the present application includes:
step 301: and after the unlocking operation is obtained, the RSSI value of the second Bluetooth module is detected by utilizing the first Bluetooth module.
In the embodiment of the application, after the terminal obtains the unlocking operation, the RSSI value of the second Bluetooth module of the vehicle is detected by using the first Bluetooth module. In practical application, a starting switch can be arranged on the vehicle, and when a user wants to unlock the vehicle, the unlocking operation information can be sent to the terminal by touching the starting switch. It should be noted that the terminal may be a mobile phone, a tablet computer, or a wearable device. The terminal is provided with a first Bluetooth module and can establish communication connection with a second Bluetooth module of the vehicle through the first Bluetooth module so as to realize vehicle unlocking through a Bluetooth technology.
Step 302: judging whether the quantity of the local RSSI data is greater than or equal to a quantity threshold value or not; if the number of the local RSSI data is larger than or equal to the number threshold, setting an experience threshold as the unlocking threshold; and if the number of the local RSSI data is smaller than the number threshold, setting a default threshold as the unlocking threshold.
In general, the closer the distance between the bluetooth module and the terminal is, the larger the RSSI value is, so that the positional relationship between the terminal and the vehicle can be determined from the RSSI value. However, since the RSSI value of the bluetooth module is greatly affected by the distance and the obstacle, even if the same terminal and vehicle are located at the same position for bluetooth connection, the RSSI value is affected by the position of the terminal (for example, the user holds the terminal in his hand, puts the terminal in a bag, or in a pocket). Therefore, the same terminal and the same vehicle are in equidistant positions, and when the bluetooth connection is performed for multiple times, the RSSI value fluctuates within a certain range due to different positions of the terminal, so that a fixed unlocking threshold value may be difficult to adapt to different unlocking scenes.
In the embodiment of the application, the terminal acquires the number of local RSSI data stored locally and judges whether the number of the local RSSI data is greater than or equal to a number threshold value or not; if the number of the local RSSI data is larger than or equal to the number threshold, setting an experience threshold as the unlocking threshold; and if the number of the local RSSI data is smaller than the number threshold, setting a default threshold as the unlocking threshold. The empirical threshold may be calculated according to the local RSSI data, or determined according to a data value distribution of the local RSSI data; or the terminal receives the experience threshold value which is sent by the cloud and updated based on the data value distribution condition of the historical RSSI data. The default threshold is the default threshold after the terminal receives the data value distribution condition which is sent by the cloud and is updated based on the historical RSSI data. It should be noted that the default threshold may be a threshold preset at the terminal and the cloud based on a large number of manual tests performed by the staff at the early stage. The default threshold may also be a threshold calculated based on previous manual test data of a worker and historical RSSI data of the cloud when the amount of historical RSSI data of the cloud is not enough to calculate the empirical threshold. The experience threshold value is divided into a locally calculated experience threshold value and a cloud-calculated experience threshold value, the locally calculated experience threshold value can be calculated by the terminal according to local RSSI data, and the cloud-calculated experience threshold value can be calculated by the cloud according to historical RSSI data. The local RSSI data are local historical unlocking RSSI data of the terminal used by the user, and the historical RSSI data of the cloud are historical unlocking RSSI data of all terminals and vehicles which are stored on the cloud and have the same model as the terminal and vehicle used by the user.
In the embodiment of the application, the unlocking threshold is determined according to the number of the RSSI data, when the number of the local RSSI data stored locally reaches the number threshold, the terminal determines an experience threshold according to the data value distribution condition of the local RSSI data, and the experience threshold is used as the unlocking threshold; when the number of the local RSSI data stored locally does not reach the number threshold, the terminal requests the cloud to obtain the updated experience threshold, that is, when the number of the local RSSI data is insufficient, the experience threshold determined based on the data value distribution condition of the historical RSSI data of the cloud is used as the unlocking threshold. Furthermore, when the number of the historical RSSI data in the cloud does not reach the number threshold, the terminal enables a default threshold as an unlocking threshold. It should be noted that the local RSSI data stored locally is historical unlocking data of the terminal itself, that is, the local RSSI data stored locally is data most related to the unlocking state and rule of the terminal, the experience threshold determined based on the data value distribution condition of the local RSSI data stored locally is the most representative of the unlocking state and rule of the terminal, and the unlocking operation is performed based on the experience threshold determined based on the data value distribution condition of the local RSSI data, so that the unlocking accuracy can be greatly ensured, and the unlocking success rate can be greatly improved. For example, if the number threshold is 100, and the number of the local RSSI data is greater than or equal to 100, the terminal may determine an empirical threshold according to a data value distribution of the local RSSI data, and if the distribution of the 100 local RSSI data is: 80% of the RSSI data are distributed below the unlocking threshold, and only 20% of the RSSI data are distributed above the unlocking threshold, so that the unlocking success rate of the terminal is low (the reason for this may be that the RSSI data of the terminal is lower than the RSSI data of terminals of the same type, or the RSSI data of the terminal is lower due to the hardware aging of the terminal, or the RSSI data of the terminal is lower due to the use habit of the user), the terminal adjusts the unlocking threshold based on the distribution condition of the 100 pieces of local RSSI data, and lowers the unlocking threshold (it should be noted that the adjustment may also be to recalculate the unlocking threshold in a preset calculation manner), so that the unlocking threshold is more adaptive to the RSSI data of the terminal, thereby improving the unlocking success rate and improving the user experience. The experience threshold value updated by the cloud end is determined according to the data value distribution condition of the RSSI data which is the same as the terminal type in the historical RSSI data of the cloud end and is the same as the unlocking vehicle type, although the historical RSSI data of the cloud end which is the same as the terminal type and is the unlocking vehicle type is selected, compared with the historical unlocking data of the terminal, the historical unlocking data of the cloud end is only the data which is secondarily related to the terminal, compared with the default threshold value which is preset in the terminal and the cloud end by workers through a large number of manual tests in the early period and is based on the data of the manual tests, the experience threshold value determined according to the data value distribution condition of the historical RSSI data of the cloud end is wider in data and more in covered scenes, therefore, the unlocking operation is performed according to the experience threshold value determined according to the data value distribution condition of the historical RSSI data of the cloud end, and the unlocking accuracy rate can be ensured to a great extent, and greatly improves the unlocking success rate. It should be noted that the determination process of the experience threshold at the cloud end is similar to the determination process of the local experience threshold, and is not described herein again. Different unlocking thresholds are dynamically selected in the embodiment of the application, and the unlocking thresholds are continuously updated and optimized based on historical unlocking data, so that the unlocking success rate is continuously improved.
In one example, the experience threshold calculated locally is calculated by the terminal according to local RSSI data, a preset number of local RSSI data are obtained from the local RSSI data from near to far based on the timestamp of the RSSI data in a local RSSI database, RSSI values are obtained from the local RSSI data, the RSSI values are sorted, and filtering is performed by a median average filtering algorithm to obtain an interval of the RSSI values, wherein the experience threshold is a coefficient of the interval minimum value-interval width × interval width. Wherein the interval minimum value is the minimum value in the interval of the RSSI values; the interval width is the data quantity in the interval of the RSSI value; the interval width coefficient is a value preset by a worker, and the value range of the interval width coefficient can be 0.1-0.8.
In one example, the experience threshold calculated by the cloud is calculated by the cloud according to historical RSSI data of the cloud. Specifically, 1) the cloud may perform statistical analysis on historical RSSI data of the cloud to obtain an empirical threshold: in a cloud RSSI database, acquiring historical RSSI data of terminals and vehicles of the same type according to the type of the terminal and the type of the vehicle used by a user, acquiring a preset number of cloud RSSI data from the cloud RSSI data from near to far based on a timestamp of the historical RSSI data, acquiring RSSI values from the cloud historical RSSI data, sequencing the RSSI values, filtering by a median average filtering algorithm to obtain an RSSI value interval, wherein an empirical threshold value is an interval minimum value-interval width multiplied by an interval width coefficient. Wherein the interval minimum value is the minimum value in the interval of the RSSI values; the interval width is the data quantity in the interval of the RSSI value; the interval width coefficient is a value preset by a worker, and the value range of the interval width coefficient can be 0.1-0.8. Or, 2) the cloud may obtain the experience threshold through a deep learning algorithm: historical RSSI data of the cloud belongs to big data, and the big data is utilized to continuously evolve the unlocking strategy model, so that the accuracy of the experience threshold can be continuously improved, and the unlocking success rate is improved. In addition, the cloud end can update the default threshold value according to historical RSSI data of the cloud end, and the updating mode can also adopt a statistical analysis mode or a deep learning mode.
In the embodiment of the present application, the unlocking threshold may be an empirical threshold or a default threshold, wherein the empirical threshold has a higher priority than the default threshold. Further, the experience threshold is divided into a locally calculated experience threshold and a cloud-calculated experience threshold, wherein the locally calculated experience threshold has a higher priority than the cloud-calculated experience threshold. It should be noted that the experience threshold and/or the default threshold calculated by the cloud may be updated to the local terminal, so that the terminal may directly obtain the experience threshold and/or the default threshold calculated by the cloud from the local terminal.
The method for updating the experience threshold and/or the default threshold by the terminal specifically comprises the following steps: whether a timestamp of a local experience threshold is beyond a validity period or not is checked, if the timestamp of the local experience threshold is beyond the validity period, a first request message is sent to a cloud end, and the first request message is used for requesting the cloud end to update the experience threshold; receiving an experience threshold value which is sent by the cloud and updated based on historical RSSI data, and storing the experience threshold value to the local; checking whether the local experience threshold is an initial threshold, if so, checking whether a timestamp of a local default threshold is beyond a valid period, and if so, sending a second request message to a cloud terminal, wherein the second request message is used for requesting the cloud terminal to update the default threshold; and receiving a default threshold value which is sent by the cloud and updated based on historical RSSI data, and storing the default threshold value to the local. After the terminal finishes updating the unlocking threshold value, if the terminal obtains the unlocking operation, the RSSI value of a second Bluetooth module of the vehicle is detected by using the first Bluetooth module. The term of validity may be set to 24 hours when actually applied.
It should be noted that, if the terminal does not update or fail to update the unlocking threshold when obtaining the unlocking operation, the terminal stops updating the unlocking threshold, and uses the last updated unlocking threshold as the latest threshold.
In the embodiment of the application, when the initial historical data of the user is insufficient, the latest reasonable threshold value is calculated for the user by using the big data according to the mobile phone type and the vehicle type used by the user.
And uploading historical unlocking data of the user to the cloud periodically to serve as a data source of the big data. The uploaded data is also used as a backup of the data of the user, and when the user downloads the data again after deleting the app, the local historical data does not need to be accumulated again and is directly obtained through the cloud. The idea is to calculate a reasonable threshold value based on historical unlocking data of a user, and improve the unlocking success rate.
In an embodiment of the present application, the RSSI data includes the RSSI value and at least one of the following information: terminal information, vehicle information, a timestamp.
Step 303: comparing the RSSI value with an unlocking threshold value, and if the RSSI value is greater than or equal to the unlocking threshold value, sending an unlocking instruction to the second Bluetooth module; the unlocking instruction is used for unlocking the vehicle, and the unlocking threshold value is determined according to the number of RSSI data.
In the embodiment of the application, after determining an unlocking threshold, the terminal compares the RSSI value with the unlocking threshold, and if the RSSI value is greater than or equal to the unlocking threshold, an unlocking instruction is sent to the second Bluetooth module; if the RSSI value is smaller than the unlocking threshold value, an unlocking instruction is not sent to the second Bluetooth module, or an unlocking failure instruction is sent to the second Bluetooth module. The vehicle can be set to send unlocking operation information and then send a prompt tone to prompt a user that the unlocking is failed if an unlocking instruction is not received within a preset time; the vehicle can also be set to send out a prompt tone to prompt a user that the unlocking fails after receiving an unlocking failure instruction sent by the terminal. The unlocking instruction is used for unlocking the vehicle.
In another embodiment of the present application, after determining an unlocking threshold, the terminal compares the RSSI value with the unlocking threshold, and if the RSSI value is greater than or equal to the unlocking threshold, the terminal sends an unlocking instruction to the second bluetooth module; and if the RSSI value is smaller than the unlocking threshold value, the terminal sends out a prompt tone or prompt information to prompt the user that the unlocking is failed.
Step 304: locally storing a piece of RSSI data, said RSSI data comprising said RSSI values and at least one of the following information: terminal information, vehicle information, a timestamp.
In this embodiment of the application, after the terminal detects the RSSI value of the second bluetooth module by using the first bluetooth module, the terminal locally stores a piece of RSSI data, where the RSSI data includes the RSSI value and at least one of the following information: terminal information, vehicle information, a timestamp. In practical application, the terminal information may include: terminal manufacturer, terminal model, terminal version, etc., and the vehicle information may include: vehicle type, vehicle serial number, etc.
Step 305: judging whether the time between the current time and the last time of uploading the RSSI data exceeds a time threshold value or not; and if the time between the current time and the last RSSI data uploading time exceeds the time threshold, uploading local RSSI data to the cloud, and locally recording the time of uploading the RSSI data.
In the embodiment of the application, after the RSSI data is stored locally, the terminal judges whether the time between the current time and the last time for uploading the RSSI data exceeds a time threshold value; if the time between the current time and the last RSSI data uploading time exceeds the time threshold, uploading local RSSI data to the cloud, and locally recording the time of uploading the RSSI data; if the time between the current time and the last time for uploading the RSSI data does not exceed the time threshold, the unlocking operation is finished; the RSSI data uploaded by the terminal is the variable quantity of the RSSI data stored locally. It should be noted that the variation of the locally stored RSSI data may be understood as the RSSI data newly stored when the terminal is unlocked this time. In practical applications, the time threshold may be set to 24 hours.
It should be noted that the historical RSSI data in the cloud is the RSSI data stored in the cloud based on the uploading operation of the terminal, that is, the historical RSSI data in the cloud is the collection of the local RSSI data uploaded by each terminal.
It should be noted that the RSSI data uploaded to the cloud by the terminal includes the RSSI value, terminal information, vehicle information, and a timestamp. Therefore, when the experience threshold is calculated by the cloud, historical RSSI data of terminals and vehicles of the same type can be selected for calculation according to the type of the terminal and the type of the vehicle used by the current user. In practical application, the terminal information may include: terminal manufacturer, terminal model, terminal version, etc., and the vehicle information may include: vehicle type, vehicle serial number, etc.
