All the above optional technical solutions can be combined arbitrarily to form an optional embodiment of the present application, and the present application embodiment is not described in detail again.
Fig. 4 is a flowchart of a control method for an automobile according to an embodiment of the present application, which is illustrated by applying the control method for an automobile to an automobile, and the control method for an automobile may include the following steps:
step 401: when the automobile detects the Bluetooth signal sent by the target terminal through the positioning main module, the positioning main module is used for positioning the target terminal to obtain the position range of the target terminal.
The target terminal can send the Bluetooth signal when the Bluetooth function is started, and when the distance between the target terminal and the automobile is short, the positioning main module of the automobile can detect the Bluetooth signal. In order to control the automobile, the automobile can position the target terminal through the positioning main module, and the position range of the target terminal is obtained.
Note that the position range is used to indicate whether the target terminal is located inside or outside the vehicle. The target terminal is a terminal capable of controlling the car, that is, the target terminal can serve as a key of the car to control the car.
As an example, the operation of the automobile locating the target terminal through the main locating module to obtain the location range of the target terminal includes: sending a first positioning signal to a target terminal through a positioning main module; when a first feedback signal returned by the target terminal is received, determining that the position range of the target terminal is in the vehicle; and when the first feedback signal returned by the target terminal is not received within the time length threshold value, determining that the position range of the target terminal is outside the vehicle. Or when the received first feedback signal of the target terminal is smaller than the intensity threshold value, determining that the position range of the target terminal is outside the vehicle; when the signal intensity of the first feedback signal is greater than or equal to the intensity threshold value, the position range where the intensity target terminal is located is in the vehicle.
It should be noted that, when the position range of the target terminal is determined in the above manner, the maximum positioning range of the positioning main module can cover the area in the vehicle, and in order to ensure the positioning accuracy, the bluetooth signal detection range is greater than the positioning range.
It should be noted that the duration threshold is set in advance according to the requirement, for example, the duration threshold is 3 seconds, 2 seconds, and the like. The signal strength threshold is also set in advance according to requirements, for example, the signal strength threshold is 10dbm (decibel-milliwatt), 5dbm, and the like.
When positioning is carried out, the positioning main module can send a first positioning signal to the target terminal, and the target terminal can return a first feedback signal to the positioning main module after receiving the first positioning signal; when the positioning main module can receive the first feedback signal, the target terminal is in the positioning range, and therefore the position range of the target terminal can be determined to be in the vehicle; when the positioning main module does not receive the first feedback signal within the time length threshold value, the target terminal is out of the positioning range, and therefore the position range of the target terminal can be determined to be outside the vehicle.
In some embodiments, the operation of the automobile for locating the target terminal through the locating main module not only includes the above manner, but also includes other manners, for example, the automobile can also send a second locating signal to the target terminal through the locating main module; determining a communication distance between the positioning main module and the target terminal and a relative angle between the positioning main module and the target terminal according to the second positioning signal; and determining the position range of the target terminal through the positioning main module according to the communication distance and the relative angle.
As an example, when the communication distance is greater than the first distance threshold, the position range of the target terminal can be determined to be outside the vehicle regardless of the relative angle; when the communication distance is smaller than or equal to the first distance threshold and larger than the second distance threshold, if the relative angle is located in the first angle range, the position range of the target terminal is determined to be inside the vehicle, and if the relative angle is located outside the first angle range, the position range of the target terminal is determined to be outside the vehicle; and when the communication distance is smaller than a second distance threshold value, if the relative angle is located within a second angle range, determining that the position range of the target terminal is outside the vehicle, and if the relative angle is located outside the second angle range, determining that the position range of the target terminal is inside the vehicle.
When the target terminal receives a second positioning signal sent by the positioning main module, the target terminal can return a second feedback signal to the positioning main module, so that the automobile can determine the communication distance between the automobile and the target terminal through the positioning main module according to the time difference between sending the second positioning signal and receiving the second feedback signal and the signal propagation speed; and when the positioning main module receives the second feedback signal, the angle for receiving the second feedback signal can be determined, and the angle is determined as the relative angle with the target terminal, so that the automobile can determine the position range of the target terminal through the positioning main module according to the communication distance and the relative angle between the positioning main module and the target terminal.
It should be noted that the first distance threshold, the second distance threshold, the first angle range, and the second angle range are set in advance according to requirements, for example, the first distance threshold is the farthest distance between the position where the main positioning module is located and the body of the automobile, and the second distance threshold is the farthest distance between the position where the main positioning module is located and the head of the automobile.
As an example, the positioning main module can be a module integrated with UWB (Ultra Wideband) and bluetooth functions, and thus the positioning main module can detect a bluetooth signal transmitted by a target terminal and can position the target terminal.
In some embodiments, the positioning master module of the car can detect the bluetooth signal transmitted by the target terminal through the low power consumption broadcast signal.
It should be noted that the target terminal may be a terminal having a bluetooth function, and an application for controlling an automobile, other communication modules, and the like may be installed in the target terminal. And the bluetooth function in the target terminal supports the common protocol bluetooth 5.1 and above.
In order to reduce the consumption of the quiescent current of the automobile, whenever the bluetooth signal of the target terminal is not detected in the vicinity of the automobile, the bluetooth function of the positioning main module is in a bluetooth low energy broadcast state, and the other functions of the positioning main module are in a sleep state.
In some embodiments, since the user may control the vehicle through the target terminal to perform more functions, the vehicle may further establish a bluetooth connection between the positioning main module and the target terminal before the positioning main module locates the target terminal, and start the positioning function of the positioning main module after establishing the bluetooth connection.
It should be noted that, when the vehicle establishes the bluetooth connection with the target terminal through the positioning main module, the authentication and identity authentication operations can be performed on the target terminal, and the authentication operations can refer to related technologies, which are not described in detail in this embodiment of the present application.
Step 402: and the automobile positions the target terminal through the plurality of positioning slave modules corresponding to the position range to obtain the position information of the target terminal.
The automobile can determine whether the target terminal is located in the automobile or outside the automobile through the positioning main module, detailed position information of the target terminal needs to be further confirmed, and the positioning slave modules used for determining the detailed position information are different due to different position ranges of the target terminal, so that the automobile needs to position the target terminal through the plurality of positioning slave modules corresponding to the position ranges of the target terminal, and the position information of the target terminal is obtained.
It should be noted that the target terminal may be located inside or outside the vehicle, and therefore, after the vehicle locates the target terminal through the plurality of positioning slave modules, the obtained position information of the target terminal may include in-vehicle position information or outside-vehicle position information.
As an example, the operation of locating the target terminal by the vehicle through the plurality of positioning slave modules corresponding to the position range where the target terminal is located to obtain the position information of the target terminal includes: when the position range of the target terminal indicates that the target terminal is outside the automobile, starting a plurality of automobile outside positioning slave modules installed outside the automobile; positioning the target terminal through a plurality of vehicle exterior positioning slave modules to obtain vehicle exterior position information of the target terminal; when the position range of the target terminal indicates that the target terminal is located in the automobile, starting a plurality of in-automobile positioning slave modules installed in the automobile; and positioning the target terminal through the plurality of in-vehicle positioning slave modules to obtain in-vehicle position information of the target terminal.
As can be seen from fig. 2, a plurality of positioning slave modules can be installed inside and outside the vehicle, and when the target terminal is located in different position ranges, the vehicle can select different positioning slave modules to perform secondary positioning on the target terminal for positioning accuracy. For ease of distinction, the plurality of off-board mounted positioning slave modules can be referred to as a plurality of off-board positioning slave modules, and the plurality of in-board mounted positioning slave modules can be referred to as a plurality of in-board positioning slave modules. And each in-vehicle positioning slave module and each out-vehicle positioning slave module can be modules integrated with UWB functions.
In some embodiments, the position information of the target terminal obtained by the vehicle from the module through a plurality of positioning may be a variable position or a fixed position. That is, the position information of the target terminal acquired by the automobile at least includes at least one of a position variation trend, a fixed position, and the like of the target terminal.
It should be noted that, the operation of locating the target terminal by the vehicle through the plurality of vehicle-exterior positioning slave modules and the operation of locating the target terminal by the vehicle through the plurality of vehicle-exterior positioning slave modules can refer to the related art, for example, the vehicle locates the target terminal through the TDOA mode, and this is not repeated one by one in the implementation of the present application.
Step 403: and the automobile controls the automobile to execute corresponding operation based on the position information of the target terminal.
Since the operation performed by the vehicle is different when the location information of the target terminal is different, the vehicle can control the vehicle to perform the corresponding operation according to the location information of the target terminal.
As an example, when the location information includes a location change trend of the target terminal, the automobile controls the automobile to perform corresponding operations based on the location information of the target terminal at least including: when the position range of the target terminal indicates that the target terminal is outside the automobile and the position change trend of the target terminal is a trend close to the automobile, if the target terminal enters a welcome area, the automobile is controlled to light the automobile, and if the target terminal enters an unlocking area, the automobile is controlled to unlock the automobile door; and when the position range of the target terminal indicates that the target terminal is outside the automobile and the position change trend of the target terminal is a trend far away from the automobile, controlling the automobile to carry out door locking operation.
When the target terminal is located outside the vehicle and the position change trend of the target terminal is a trend of approaching the vehicle, it indicates that the user approaches the vehicle, and then the user is likely to need to drive the vehicle, so that the vehicle can perform a door unlocking operation. When the target terminal is located outside the automobile and the position change trend of the target terminal is a trend away from the automobile, it indicates that the user is away from the automobile, and then the user is likely not to need to drive the automobile, so the automobile can perform the door locking operation.
It should be noted that the welcome area and the unlocking area of the automobile can be divided in advance according to requirements. After the automobile lights are turned on in the welcoming area, a user can observe the lighting condition of the automobile lights and the area of the surrounding environment of the automobile body, and the welcoming area can be overlapped with the unlocking area.
In some embodiments, the location information outside the vehicle may be obtained by the vehicle through a plurality of vehicle-outside positioning slave modules after the user moves from inside to outside of the vehicle, that is, since the location change of the user may be a change from inside to outside of the vehicle, the vehicle may detect that the location range of the target terminal changes from inside to outside of the vehicle through the main positioning module, and when the location range of the target terminal changes to outside of the vehicle, the vehicle may position the target terminal through the plurality of vehicle-outside positioning slave modules to obtain the vehicle-outside location information. In such a case, in order to avoid that the user forgets a child in the automobile, when it is detected that the position range of the target terminal is changed from the inside of the automobile to the outside of the automobile and the position information outside the automobile of the target terminal includes a tendency that the position change tendency of the target terminal is far away from the automobile, the automobile can perform living body detection on the environment inside the automobile through the plurality of in-automobile positioning slave modules; when other living bodies exist in the vehicle, sending second prompt information to the target terminal; and when detecting that no other living bodies exist in the automobile, controlling the automobile to perform door locking operation.
As an example, the location information can further include a fixed and invariable location of the target terminal, and thus, the controlling of the automobile to perform the corresponding operation according to the location information of the target terminal by the automobile at least includes: and when the position information outside the vehicle of the target terminal comprises that the target terminal is positioned at the tail of the vehicle outside the vehicle, and the stay time at the tail of the vehicle is longer than a first preset time, controlling the vehicle to open or close the trunk.
As an example, when the target terminal is located in a car, the target terminal is rarely moved, and therefore, the position information detected by the car may include a fixed and unchangeable position of the target terminal, and the control performed on the car is related to not only the position of the target terminal in the car but also the current operating state of the car. Therefore, the controlling the car to perform the corresponding operation based on the location information of the target terminal by the car can further include: when the target terminal is located in the automobile, the automobile can be controlled to execute corresponding operation according to the position information in the automobile of the target terminal and the current running state of the automobile.
In some embodiments, when the target terminal is located in the vehicle and the in-vehicle location information of the target terminal includes that the stay time of the target terminal in the position of the driver seat of the vehicle is longer than a second preset time and the vehicle is currently in a starting state, controlling the vehicle to start a navigation function and/or a multimedia function; when the target terminal is located in the automobile, the in-automobile location information of the target terminal comprises that the stay time of the target terminal in the position of the automobile driver seat is longer than a third preset time, and the automobile is currently in a starting state, controlling the automobile to open an air conditioner or a window or a skylight according to the current weather state; when the target terminal is located in the automobile and the door of a driver seat of the automobile is detected to be opened, the position of the target terminal is prompted through third prompt information according to the position information in the automobile of the target terminal, and the third prompt information can prompt a user to carry the prompt information of the target terminal.
It should be noted that the first preset time, the second preset time, and the third preset time can be set in advance according to requirements, for example, the first preset time is 3 seconds or 5 seconds, the second preset time is 3 seconds or 5 seconds, and the third preset time is 3 seconds or 5 seconds.
In some embodiments, since the user may drop the target terminal in the vehicle and forget the drop position, the vehicle can use a plurality of in-vehicle positioning slave modules to position the specific position of the target terminal in the vehicle, and therefore, the user can search for the target terminal through the search function of the vehicle. The automobile can also receive a search instruction aiming at the target terminal, and when the position range of the target terminal indicates that the target terminal is located in the automobile, the automobile can prompt the position of the target terminal in the automobile through the first prompt information according to the position information of the target terminal.
In some embodiments, since the user may also use the automatic parking function of the automobile, and the automobile sometimes requires the user to be located outside the automobile when performing the automatic parking function, and the user cannot be too close to or too far away from the automobile, the automobile can also determine whether the target terminal is in a parking safety region outside the automobile through a plurality of automobile outside positioning modules, and control the automobile to perform automatic parking when the target terminal is in the parking safety region. That is, the automobile can also detect the service condition of the automatic parking function of the automobile before controlling the automobile to execute corresponding operation based on the position information of the target terminal; when the position range of the target terminal indicates that the target terminal is outside the automobile and the target terminal target position is in a parking safety region based on the in-automobile position information of the target terminal, if the automatic parking function of the automobile is started and the automatic parking track is obtained, the automatic parking of the automobile is controlled through the automatic parking track.
The parking safety area can be divided in advance according to the requirement.
In some embodiments, before the automobile is controlled to perform the corresponding operation according to the position information of the target terminal, fourth prompt information for prompting the operation performed by the automobile may be further sent to the target terminal.
Because sometimes the user may not need to control the automobile, in order to accurately control the automobile, the automobile may further send fourth prompt information to the target terminal before controlling the automobile to execute corresponding operations according to the position information of the target terminal, and when the user needs to control the automobile, the user may not perform any operation on the target terminal or trigger a confirmation operation instruction through the target terminal. When the user does not need to control the automobile, a cancel operation instruction can be triggered through the target terminal, and the cancel operation instruction is used for indicating the automobile to cancel and controlling the automobile to execute corresponding operation according to the position information of the target terminal.
In the embodiment of the application, when the automobile detects a bluetooth signal sent by the target terminal, the automobile can establish connection with the target terminal through the positioning main module, position the target terminal through the positioning main module to obtain the position range of the target terminal, and then accurately position the target terminal through the corresponding positioning slave modules according to the position range of the target terminal, so that the accuracy of positioning the target terminal is improved. Meanwhile, the control of the automobile can be realized without the operation of the target terminal by the user, so that the operation of controlling the automobile is simplified, and in addition, the possibility that the user forgets the target terminal is very small, so that the automobile is controlled by the target terminal, the potential safety hazard of the automobile is reduced, and the control safety of the automobile is improved.
