Given that the current mainstream vehicle types adopt Bluetooth and mobile phone communication, some medium and low distribution vehicle types all adopt a single-antenna Bluetooth scheme, when a user approaches a vehicle from a far place, a digital key APP (application) on the mobile phone can be connected with a vehicle-mounted Bluetooth controller, the mobile phone provides authentication information for the vehicle-mounted Bluetooth controller, and after the authentication is passed, Bluetooth connection is established. After the bluetooth connection is completed, the bluetooth controller on the vehicle detects the Received bluetooth Signal Strength RSSI (Received Signal Strength Indication) in real time, judges the distance between the vehicle and the user mobile phone through the RSSI, and sends an unlocking instruction to the vehicle when the distance between the user mobile phone and the vehicle is shortened to a certain distance (for example, 3 m) to complete the unlocking. In the process, no operation is carried out by a user, and the operation is very convenient. When the user finishes using the vehicle and finishes parking and leaving, the Bluetooth controller on the vehicle detects the received Bluetooth signal strength RSSI in real time, judges the distance between the vehicle and the mobile phone of the user according to the RSSI strength, and sends a vehicle locking command to the vehicle when the mobile phone of the user leaves the vehicle for a certain distance (such as 6 m) so as to realize automatic vehicle locking. The current scheme has the following problems:
1. when a user leaves a vehicle after using the vehicle, because the fluctuation of the RSSI of the bluetooth signal strength is large, when the mobile phone of the user is in an area between an unlocking threshold (such as 3 m) and a locking threshold (such as 6 m), the RSSI value is easily switched back and forth between the two thresholds, so that the situation that the user unlocks after locking is easily repeated occurs.
2. When a user approaches a vehicle and enters an unlocking threshold value (such as 3 m) range, after the vehicle is unlocked, when the user walks around the vehicle (within the unlocking threshold value range), due to the irregular shape of the vehicle, a bluetooth signal dead zone exists at the front left 45-degree angle position, the front right 45-degree angle position and the rear side of the vehicle, and in the dead zone range, the intensity RSSI (received signal strength) of a bluetooth signal received by a bluetooth controller is greatly reduced, so that the false locking is caused.
3. When a user mobile phone approaches a vehicle from a far place, the fluctuation of the RSSI of the Bluetooth signal intensity is large, the influence of the state of the mobile phone (the mobile phone is exposed outside or placed in a pocket of clothes) and the height of the mobile phone on the RSSI is large, so that the unlocking distance is inaccurate, the mobile phone can be unlocked at a far place outside an unlocking threshold value, and can also enter the unlocking threshold value range and still be unlocked, and meanwhile, the situation of repeated unlocking and locking can also be caused. Therefore, the distance is judged by only depending on the RSSI (received signal strength indicator) of the received Bluetooth signal intensity of the vehicle-mounted Bluetooth controller, and the accuracy is not high.
In an exemplary embodiment of the present application, a digital key based automatic unlocking and locking method (as shown in fig. 2, in which an arrow indicates a moving direction of a user terminal): when a user approaches the vehicle to be within the unlocking threshold (for example, 3 m), sending an unlocking instruction to a CEM (Central Electronic Module) controller by a near field communication controller (which may include but is not limited to a Bluetooth controller, an ultrasonic controller, a contact-free radio frequency identification RFID controller, and the like) to realize unlocking; when the user uses the vehicle and leaves the vehicle to a locking threshold (for example, 6 m), the near field communication controller sends a locking instruction to the CEM controller to realize locking, and the near field communication controller automatically judges and realizes corresponding functions without manual operation of the user in the whole process. According to the scheme of the embodiment of the application, the measurement of the mobile distance by the terminal is introduced on the basis of the scheme of automatic unlocking and locking, and the vehicle unlocking and locking are realized according to the measured mobile distance, so that the control of the terminal side is increased in vehicle control, the distance judgment by simply depending on the RSSI (received signal strength indicator) of the near field communication signal is avoided, the accuracy of unlocking and locking is greatly improved, and the repeated unlocking and locking in a critical area is avoided.
In the exemplary embodiment of the present application, the scheme of the embodiment of the present application may be implemented based on a preset digital key system. The association of the digital key system may be as shown in fig. 3, where the dotted line represents wireless communication and the solid line represents wired communication. The realization of the digital key automatic unlocking and locking related functions is mainly realized by a user terminal digital key platform [ can include but is not limited to: in the embodiment of the present application, the terminal digital key APP is mainly taken as an example to be described, and the near field communication controller, the CEM controller (i.e., the vehicle body controller) and the vehicle lock are implemented together.
In an exemplary embodiment of the present application, the user's terminal may include, but is not limited to: a cell phone, a portable computer, a tablet, a smart wearable device (e.g., which may include, but is not limited to, a smart watch, smart glasses, a smart helmet, a smart bracelet, a smart pocket watch, a smart ring, a smart necklace, a smart headset, etc.), and the like.
In an exemplary embodiment of the present application, the terminal digital key APP: the method comprises the steps that a vehicle-mounted near field communication controller is set to be actively connected, and identity authentication is carried out; realizing information interaction with the near field communication controller; recording and storing self positioning information, recording self track, and calculating the moving distance in real time;
a near field communication controller: may include but is not limited to a bluetooth controller, configured to connect with the terminal digital key APP and verify the validity of the terminal digital key; calculating the received terminal Bluetooth signal strength RSSI in real time, calculating the distance between a terminal digital key APP and a vehicle through the RSSI, and sending an unlocking signal to a CEM controller when a user approaches the vehicle and is within the range of an automatic unlocking threshold value; when the user leaves the vehicle outside the automatic lockout threshold range, a lockout signal is sent to the CEM controller. When the vehicle is flamed out, a vehicle flameout signal is sent to the terminal digital key APP; when the vehicle is switched from the running mode to flameout, a user leaving prompt signal is sent to the terminal digital key APP at the moment that the main driving door is opened or the main driving door is closed;
CEM controller: the device is set to receive an unlocking instruction of the near field communication controller to realize unlocking, or receive a locking instruction of the near field communication controller to realize locking, and provide a vehicle body state signal and the like for the near field communication controller.
Vehicle locking: to a specific actuator for actuating the unlocking or locking of the door.
In an exemplary embodiment of the present application, a method for automatically locking a vehicle is a method for measuring a moving distance and controlling the automatic locking of the vehicle by a terminal according to vehicle state information after the vehicle is used by a vehicle owner.
In an exemplary embodiment of the present application, the vehicle state information may include any one or more of: the system comprises vehicle flameout information, information that a main driving side door is opened, information that the main driving side door is closed within a preset time after being opened, and main driving seat unmanned information.
In an exemplary embodiment of the present application, for example, after the vehicle is turned off and the vehicle owner leaves the vehicle, the CEM controller sends the vehicle turning off information and the information that the vehicle door on the main driving side is closed within a preset time period after being opened to the terminal (specifically, the information may be sent to a near field communication controller on the terminal side, such as a bluetooth controller), and the terminal digital key APP in the terminal may determine that the vehicle is used up according to the vehicle state information, and may start to execute the automatic locking scheme according to the embodiment of the present application.
In an exemplary embodiment of the application, the bluetooth controller may periodically receive the vehicle state information of the CEM controller, and when the bluetooth controller detects that the vehicle is switched from the running state to the flameout state, or the main driving side door is opened after the flameout state, or the main driving side door is closed again after the flameout state, the terminal may determine that the vehicle is completely used, and at the time when the above vehicle state information is detected, the relative position between the terminal and the vehicle is fixed (for example, at the moment of flameout, the mobile phone is in the vehicle, and the time when the main driving side door is opened or closed after the flameout state, considering the moving speed of the person, the mobile phone is considered to be beside the main driving side door). The times can be used as the time for locking the relative position between the vehicle and the user terminal, and when the method is actually applied, any one of the times for detecting any one type of vehicle state information can be flexibly selected as the time for locking the position between the vehicle and the terminal. In the embodiment of the application, the moment when the vehicle is flamed out can be selected as the moment for triggering the current position of the locking terminal by default, and the moment when the main driving side door is opened or closed after flameout is not repeated.
In an exemplary embodiment of the present application, the method may further include:
after receiving the vehicle state information, sending a confirmation signal to the vehicle;
and after the vehicle receives the confirmation signal, receiving the authority transferred by the vehicle for unlocking and locking the vehicle.
In an exemplary embodiment of the application, at the time of vehicle flameout, the CEM controller may send a user leaving prompt signal (for example, vehicle state information) to the terminal digital key APP through the near field communication controller in the vehicle, after receiving the user leaving prompt signal, the terminal digital key APP sends an acknowledgement signal to the near field communication controller in the vehicle, and after receiving the acknowledgement signal, the near field communication controller in the vehicle no longer controls unlocking and locking of the vehicle door, and may control unlocking and locking of the vehicle door by the terminal digital key APP.
In an exemplary embodiment of the present application, the locating the current position of the terminal according to the vehicle state information and obtaining the origin position of the terminal may include:
positioning the terminal by adopting a preset positioning method, and acquiring a current positioning position;
and establishing a preset coordinate system, taking the positioning position as the origin of coordinates of the coordinate system, and acquiring the origin position of the terminal.
In an exemplary embodiment of the present application, the preset positioning method may include, but is not limited to:
and positioning the current position of the terminal through a position sensor and/or a software positioning system built in the terminal.
In the exemplary embodiments of the present application, a detailed embodiment scheme for locating the current position of the terminal through a position sensor built in the terminal itself is described below.
In an exemplary embodiment of the application, after the moment of locking the current position of the terminal is triggered, the terminal may record the current position of the terminal itself (with the position as an origin, which may be referred to as an origin position), and then the terminal may calculate a moving distance of the terminal itself (i.e., a distance between the position to which the terminal moves and the origin position) through a position sensor (e.g., an acceleration sensor and a gyroscope) built in the terminal itself, when the moving distance reaches a preset locking threshold (here, the first distance threshold may be 6m, for example), the terminal digital key APP sends a locking instruction to the onboard bluetooth controller, and after receiving the locking instruction, the onboard bluetooth controller sends a locking instruction to the CEM controller, so as to achieve automatic vehicle locking.
In the exemplary embodiment of the application, the automatic locking method is based on a terminal digital key APP to perform distance calculation, completely depends on a position sensor (an acceleration sensor and a gyroscope, and an intelligent terminal is calibrated) arranged in a terminal, does not depend on positioning information of a vehicle after an original position is locked, is suitable for an underground garage and the ground, and greatly improves the applicability and the convenience of the scheme.
In an exemplary embodiment of the present application, the interactive data format of the bluetooth controller and the terminal digital key APP may be as shown in table 1:
TABLE 1
In an exemplary embodiment of the application, the method triggers the terminal digital key APP to receive the time when the user leaves the vehicle through the change of the vehicle state (flameout) or the state of the main driving side door, positions the position of the terminal at the moment as the original position, and records the moving distance of the subsequent user, so that the situation that the distance from the user to the vehicle is judged only through the RSSI is avoided, and the judgment accuracy is greatly improved; and the self moving distance is calculated through a position sensor (an acceleration sensor and a gyroscope) arranged in the terminal, the limitation and the influence of an RSSI dead zone are avoided, the user experience is further greatly improved, and the problem of control operation failure caused by the RSSI dead zone is avoided.
In an exemplary embodiment of the present application, the recording of the home position of the terminal itself by the terminal digital key APP may include: when the terminal digital key APP receives a user leaving prompt signal sent by the near field communication controller, a coordinate system (which may include but is not limited to a rectangular coordinate system, a longitude and latitude coordinate system, etc.) is established immediately, and the position of the terminal itself is taken as the origin of the coordinate system. At this time, the position of the terminal itself represents the position of the vehicle (because the terminal is still in the vehicle together with the user or beside the vehicle door at this time), and at this time, the terminal digital key APP records the position of itself, and establishes a coordinate system based on a position sensor (e.g., an acceleration sensor and a gyroscope) built in the mobile phone instead of positioning information based on GPS (global positioning system) or beidou navigation, and places the current position of the terminal at the origin of the coordinate system.
In the exemplary embodiment of the application, in the process that the user leaves the vehicle to move, the terminal digital key APP calculates the moving distance of the terminal itself relative to the above-mentioned origin in real time, and specifically, the terminal digital key APP may also calculate the planar moving distance of the user in real time through a position sensor built in the mobile phone.
In an exemplary embodiment of the present application, when the moving distance (relative origin position) of the terminal digital key APP itself calculated by the terminal digital key APP is greater than a preset locking threshold (the above-mentioned first distance threshold), the terminal digital key APP sends a locking instruction to the near field communication controller, and the near field communication controller sends a locking instruction to the CEM controller, so as to complete a locking action. When the locking is finished, the near field communication controller in the vehicle still does not control the unlocking and locking of the vehicle door (does not depend on RSSI control), and continues to control the unlocking and locking of the vehicle door by the terminal digital key APP.
In the exemplary embodiment of the present application, with the above-described embodiment scheme, the relative position between the vehicle and the terminal digital key APP (i.e. the terminal is in the vehicle or beside the main driving door) is locked based on the triggering condition (e.g. key-off, opening the main driving door, closing the main driving door, etc.), the terminal digital key APP uses this as the origin, the distance from the origin is calculated by the position sensor built in the terminal, when the distance is greater than the locking threshold value, the terminal digital key APP sends a locking instruction to the vehicle, so that the control accuracy is greatly improved, and the problems that the distance is judged only through the near field communication signal strength RSSI received by the vehicle-mounted near field communication controller in the current related technical scheme, the RSSI stability is poor, the fluctuation is large, the accuracy of automatic locking is not high, and misoperation outside the range or timely action within the range frequently occurs are solved.
In the exemplary embodiment of the application, for a critical area between unlocking and locking in the current related technical scheme, repeated unlocking and locking are easy to occur, and the problem of influencing user experience is solved. According to the embodiment of the application, after the mode of automatic locking is optimized, the moving track of the terminal digital key APP is calculated, the automatic locking is also optimized, the problem that locking is repeatedly unlocked in a critical area is solved, and user experience is greatly improved.
In the exemplary embodiment of the present application, a detailed embodiment scheme for positioning the current position of the terminal through a software positioning system built in the terminal itself is described below. In an exemplary embodiment of the present application, locating the current position of the terminal according to the vehicle state information may further include:

and detecting whether the signal intensity of the software positioning system is greater than or equal to a preset second intensity threshold, starting a process of positioning the current position of the terminal according to the vehicle state information when the signal intensity of the software positioning system is greater than or equal to the second intensity threshold, and storing the original point position of the terminal obtained by positioning.
In the exemplary embodiment of the present application, in the case that the terminal positioning signal (which may be a positioning signal of a GPS or a beidou, etc.) is in a good state, the terminal may record the positioning information after parking (i.e., the origin position of the terminal) and store the information in the terminal, and the origin position may be still used as a criterion for calculating the distance to the vehicle when the user gets the vehicle again next time.
In an exemplary embodiment of the present application, after a first preset time period after locking the vehicle, the method may further include:
after establishing the near field communication with the vehicle again, positioning the terminal by adopting a preset positioning method, and acquiring a first position of the terminal;
acquiring an origin position of the terminal, and calculating a difference value between the origin position and the first position;
when the difference value is smaller than or equal to a preset second distance threshold value, an unlocking allowing signal is sent to the vehicle, so that the vehicle can be unlocked automatically according to the unlocking allowing signal; wherein the second distance threshold is less than the first distance threshold.
In an exemplary embodiment of the present application, the second distance threshold is less than the first distance threshold; the third distance threshold may be equal to the second distance threshold, and 3m may be selected.
In an exemplary embodiment of the present application, the first preset time period may be self-defined according to different vehicle types or different application scenarios or different requirements, and is not limited to a specific value, for example, but may include, but is not limited to, 15 minutes, half an hour, one hour, and the like, and is used for defining whether the current location of the terminal is that the user returns to the location of the terminal to unlock the vehicle when using the vehicle, or that the user continuously positions the terminal due to continuous loitering around the vehicle.
In the exemplary embodiment of the application, if the time length from the current time to the vehicle locking exceeds a first preset time length, the user can be determined to take the vehicle again, at this time, the positioning information of the current terminal (namely, the first position of the terminal) and the positioning information recorded before (namely, the origin position of the terminal) can be compared, and when the distance between the first position and the origin position of the terminal is smaller than an unlocking threshold value, the terminal digital key APP sends an unlocking instruction to the vehicle-mounted near field communication controller, so that unlocking is realized.
In the exemplary embodiment of the application, the unlocking scheme can be compatible with a method for unlocking by receiving the near field communication signal strength RSSI, and the problem of insufficient stability and accuracy when unlocking by only using the near field communication signal strength RSSI is solved.
In an exemplary embodiment of the present application, after the nfc controller detects that the vehicle is turned off, a vehicle turned-off signal (i.e., vehicle state information) may be sent to the terminal digital key APP, and after the terminal digital key APP receives the vehicle turned-off signal, the current positioning signal strength of the terminal may be immediately determined (e.g., none, low, medium, or high), and if the current positioning (GPS or beidou) signal strength is high (e.g., the signal strength of the software positioning system is greater than or equal to the second strength threshold), the terminal digital key APP may immediately record the current positioning information of the terminal (i.e., the origin position of the terminal), and store the current positioning information as the vehicle position for standby. If the current terminal positioning signal strength is zero or low (for example, the signal strength of the software positioning system is smaller than a second strength threshold), it is judged that the current positioning error is larger according to the terminal self software positioning system, the terminal software positioning system can be not adopted for positioning, the original method for judging the distance based on the RSSI is continuously used, and the terminal digital key APP can reply the result of whether the current positioning information (the origin position of the terminal) is recorded to the vehicle-mounted near field communication controller.
In the exemplary embodiment of the application, after the user leaves the vehicle, the vehicle is automatically locked, and after the user leaves a certain distance, the near field communication connection between the vehicle and the terminal is also disconnected.
In an exemplary embodiment of the present application, after locking the vehicle, the method may further include:
when the distance between the terminal and a vehicle is smaller than or equal to the second distance threshold, an unlocking allowing signal is sent to the vehicle, so that the vehicle judges whether the near field communication signal intensity between the vehicle and the terminal is larger than or equal to a preset first intensity threshold, and when the near field communication signal intensity is larger than or equal to the first intensity threshold, the vehicle unlocks by itself; wherein the second distance threshold is less than the first distance threshold.
In the exemplary embodiment of the application, after the vehicle-mounted near field communication controller sends a signal that a user starts parking and leaving to the terminal digital key APP, the relative position of the terminal digital key APP and the vehicle is determined, then the vehicle-mounted near field communication controller grants unlocking and locking authority to the terminal digital key APP, the terminal digital key APP judges the distance from the terminal to the vehicle through the motion track of the terminal, and a locking instruction is sent when the distance exceeds a locking threshold (namely, a first distance threshold). After locking, even if the intensity RSSI of the near field communication signal received by the vehicle-mounted near field communication controller is greater than an unlocking threshold (i.e. a first intensity threshold), the vehicle-mounted near field communication controller is still unlocked, when the distance between the terminal itself and the vehicle, which is calculated by the terminal digital key APP, is within the range of the unlocking threshold (e.g. a second distance threshold described later), the terminal digital key APP sends an unlocking-allowed signal to the vehicle-mounted near field communication controller, and then the vehicle-mounted near field communication controller judges whether the received RSSI is greater than the unlocking threshold (i.e. the first intensity threshold), and if the RSSI is greater than the unlocking threshold (i.e. the first intensity threshold), the vehicle-mounted near field communication controller realizes unlocking. The embodiment scheme effectively avoids repeated unlocking and locking in a critical area between the unlocking threshold value and the locking threshold value, and improves the unlocking and locking accuracy.
In an exemplary embodiment of the present application, for another application scenario: after the terminal digital key APP is locked, before the action range of the near field communication is not exceeded, the distance from the terminal to the original point can still be continuously calculated, and if the distance is detected to be smaller than a preset unlocking threshold value (namely a second distance threshold value), an unlocking instruction can be sent to the near field communication controller to complete unlocking. The scene is that the user returns to the vehicle again after leaving the vehicle for a certain distance, and when the user enters the unlocking threshold range again, the terminal digital key APP realizes unlocking.
In the exemplary embodiment of the application, after receiving a locking instruction or an unlocking instruction of a terminal, the near field communication controller sends a corresponding locking instruction or unlocking instruction to the CEM controller, and controls a vehicle to realize locking or unlocking, and the CEM controller may feed back an execution result to the terminal digital key APP for displaying. In the exemplary embodiment of this application, when the user comes back again and uses the vehicle, when the terminal was close to the vehicle to a certain distance, terminal digital key APP automatic connection is on-vehicle near field communication controller, and near field communication controller is after near field communication connection establishes, gives terminal digital key APP with unblock threshold value and shutting threshold value synchronization.
In the exemplary embodiment of the application, after the near field communication connection is established, the terminal digital key APP may determine whether to unlock in a manner of positioning through a software positioning system of the terminal itself according to the strength of a current positioning signal (e.g., a GPS signal or a beidou positioning signal). If the current positioning signal intensity of the software positioning system of the terminal is not high, unlocking by the positioning signal of the software positioning system of the terminal, and unlocking by the near field communication controller through RSSI; if the current positioning signal intensity of the software positioning system of the terminal is high, then the positioning signal of the software positioning system of the terminal self unlocks, the terminal reads the vehicle position stored before (the original point position of the terminal) through reading the current positioning information (the first position), calculates the distance between the original point position and the first position of the terminal, works as when the distance between the original point position and the first position of the terminal is less than the unlocking threshold value, the terminal digital key APP sends an unlocking instruction to the near field communication controller, and the unlocking is realized. In the process of unlocking through positioning, the unlocking mode is realized in a compatible mode through an RSSI mode, the near field communication controller reads the vehicle state information from the CEM controller, and when the vehicle is unlocked, the unlocking is not repeated.
In the exemplary embodiment of the application, aiming at a method that a digital key is realized by only depending on a Bluetooth signal strength RSSI numerical value in the current related technical scheme, the scheme of the embodiment of the application provides a method compatible with terminal positioning information (GPS or Beidou and the like), and only the positioning information of the terminal is needed, and the positioning information of a vehicle is not needed. In the prior art, the positioning accuracy of a terminal is continuously improved, and particularly, the positioning accuracy of the terminal with an RTK (Real-time kinematic) function is up to centimeter level. Through the relative position (the moment of putting out a fire triggers) of binding vehicle and terminal, when using the vehicle again, compare current locating position and the locating position of record before through terminal digital key APP, increased substantially automatic unblock precision, moreover, only can accomplish this function through the software positioning system in the terminal, need not to fix a position the vehicle, the effectual relative error that has reduced.
In the exemplary embodiment of the application, the related algorithm and calculation of unlocking and locking are concentrated in the vehicle-mounted Bluetooth controller in the current related technical scheme, and the calculation resources of the vehicle-mounted Bluetooth controller are occupied relatively.
