[0001] The embodiments of the present application relate to the field of smart cars, and more specifically, to a calibration method, device, and system. Background Art

[0002] As smart cars become more widely used in daily life, users expect smart cars and related devices to provide a more comfortable and intelligent experience. Against this backdrop, digital key technology has emerged.

[0003] The main function of digital key technology is to allow users to establish a connection with their vehicle using a mobile phone or other terminal device, unlocking the vehicle doors when the phone approaches the vehicle from a distance, or locking the doors when the phone moves away from the vehicle. However, before implementing this technology, the vehicle must be calibrated based on received signal strength indication (RSSI). Different mobile phone wireless modules and antenna designs vary significantly, resulting in significant differences in received signal strength across vehicles. This leads to low calibration accuracy, seriously affecting the user's seamless unlocking and locking experience.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a calibration method, device, and system that can make the calibration of a vehicle more accurate, thereby improving the user experience of using digital key technology for contactless unlocking and locking.

[0006] In a first aspect, a calibration method is provided, which is applied to a mobile terminal, and the method includes: the mobile terminal receives a first message sent by a vehicle, the first message including location information of at least one first calibration point; the mobile terminal prompts a user to move to the at least one first calibration point based on the first message, and a first signal sent by the mobile terminal corresponding to the at least one first calibration point is used for calibration of the mobile terminal.

[0007] Among them, the mobile terminal can be a terminal device with Bluetooth connection capability, such as a tablet computer, mobile phone, smart watch, wearable device, etc.

[0008] Exemplarily, the first signal sent by the mobile terminal corresponding to at least one first calibration point can be understood as: the first signal sent by the mobile terminal when it is located at the position of at least one first calibration point or at a position near at least one first calibration point.

[0009] Exemplarily, the first signal is used for calibration of the mobile terminal, which can be understood as: the vehicle can complete the calibration of the mobile terminal at at least one first calibration point according to the first signal.

[0010] In an embodiment of the present application, a mobile terminal can receive the location information of at least one calibration point from a vehicle and, based on the location information of the at least one calibration point, prompt the user to move to the at least one calibration point, thereby completing the calibration. This approach can make vehicle calibration more accurate, thereby improving the user experience of seamless unlocking and locking using digital key technology.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the first message also includes a calibrated route, and the calibrated route includes: the at least one first calibration point, and a recommended route between the second calibration point and the third calibration point, the second calibration point and the third calibration point are calibration points included in the at least one first calibration point, and the method also includes: the mobile terminal displays the calibrated route.

[0012] Among them, the second calibration point and the third calibration point can both be the first calibration point, and the recommended route between the second calibration point and the third calibration point can be a straight line, a broken line, a curve, etc., which is not limited in this embodiment of the present application.

[0013] Optionally, the recommended route between the second and third marking points may be an optimal recommended route, ie, the distance the user moves from the second marking point to the third marking point is the shortest.

[0014] Optionally, although the marked route includes a recommended route including the second marked point and the third marked point, the user may not move from the second marked point to the third marked point according to the recommended route.

[0015] In an embodiment of the present application, a calibration route may be included in the first message, and the mobile terminal may display the calibration route. In this way, the user may move from the second calibration point to the third calibration point according to the prompt of the calibration route, thereby completing the calibration of at least one first calibration point.

[0018] In an embodiment of the present application, a mobile terminal can receive first position information from a vehicle and determine a path to at least one first calibration point based on the first position information. In this manner, the mobile terminal does not need to perform its own positioning and can determine the path to at least one first calibration point simply based on the first position information sent by the vehicle.

[0020] In an embodiment of the present application, the mobile terminal can obtain its own positioning information and determine the path information to reach at least one calibration point based on the positioning information. In this way, the vehicle does not need to measure the distance and angle of the mobile terminal relative to the vehicle, which can reduce the information interaction between the mobile terminal and the vehicle.

[0021] In combination with the first aspect, in certain implementations of the first aspect, before the mobile terminal receives the first message sent by the vehicle, the method further includes: the mobile terminal sends a first indication message to the vehicle, and the first indication message is used to request the vehicle to start calibration.

[0022] In an embodiment of the present application, after the mobile terminal instructs the vehicle to start calibration, the mobile terminal can receive the location information of at least one first calibration point sent by the vehicle. In this way, the vehicle can be prevented from pushing the location information of the calibration point for no reason, making it easier for the user to control the entire calibration process.

[0023] In combination with the first aspect, in certain implementations of the first aspect, the method also includes: the mobile terminal receives second indication information sent by the carrier, the second indication information is used to indicate that the mobile terminal moves from a fourth calibration point to a fifth calibration point, or indicates that the fourth calibration point has been successfully calibrated, and the fourth calibration point and the fifth calibration point are calibration points included in the at least one first calibration point.

[0024] The fourth calibration point and the fifth calibration point may both be the first calibration point.

In this way, the mobile terminal can be informed of the vehicle's calibration status for the current calibration point, thereby prompting the user to move to the next calibration point in a timely manner.

[0026] In combination with the first aspect, in some implementations of the first aspect, the method further includes: the mobile terminal prompting the user that the fourth calibration point is successfully calibrated, or prompting a recommended route from the fourth calibration point to the fifth calibration point.

[0027] In an embodiment of the present application, after the fourth calibration point is successfully calibrated, the mobile terminal can prompt the user that the fourth calibration point is successfully calibrated, or prompt a recommended route from the fourth calibration point to the fifth calibration point. In this way, the user can promptly know the calibration status of the current calibration point and move to the next calibration point.

[0030] For example, the vehicle may perform a calibration operation at at least one first calibration point by comparing the strength and / or quality of the first signal with the strength and / or quality of a preset signal in the vehicle. If the strength and / or quality of the first signal and / or quality are the same or similar, the calibration of the at least one first calibration point is successful. After the calibration is successful, when the mobile terminal moves near the at least one first calibration point again, the mobile terminal may automatically unlock or lock the vehicle doors.

[0031] In an embodiment of the present application, a vehicle can transmit the location information of at least one calibration point to a mobile terminal and perform a calibration operation based on the strength and / or quality of a first signal transmitted by the mobile terminal.

[0075] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0076] Figure 1 is a functional schematic diagram of a vehicle 100 provided in an embodiment of the present application. It should be understood that Figure 1 and the related description are merely examples and do not limit the vehicle in the embodiment of the present application.

[0077] Vehicle 100 may include various subsystems, such as a sensing system 120, a computing platform 130, and a digital key system 140. Alternatively, vehicle 100 may include more or fewer subsystems, and each subsystem may include one or more components. Furthermore, each subsystem and component of vehicle 100 may be interconnected via wired or wireless means.

[0078] The perception system 120 may include several sensors for sensing information about the environment surrounding the vehicle 100. For example, the perception system 120 may include a positioning system, which may be a global positioning system (GPS), a Beidou system, or other positioning systems. The perception system 120 may include one or more of an inertial measurement unit (IMU), a laser radar, a millimeter-wave radar, an ultrasonic radar, and a camera.

[0079] Some or all functions of the vehicle 100 can be controlled by a computing platform 130. The computing platform 130 may include processors 131 to 13n (n is a positive integer). A processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of a hardware circuit. The logical relationship of the hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration file to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, the processor may also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. In addition, the computing platform 130 may also include a memory for storing instructions, and some or all of the processors 131 to 13n may call the instructions in the memory to implement corresponding functions.

[0080] The computing platform 130 can control functions of the vehicle 100 based on input received from various subsystems, such as the perception system 120. For example, the computing platform 130 can control the opening or closing of a vehicle door based on input received from the perception system 120. In some embodiments, the computing platform 130 can be used to provide control over many aspects of the vehicle 100 and its subsystems.

[0081] The digital key system 140 can perform functions such as digital key authentication, calibration, and management of digital key usage.

[0082] Optionally, the above components are only an example. In actual applications, the components in the above modules may be added or deleted according to actual needs. Figure 1 should not be understood as a limitation to the embodiments of the present application.

[0083] The vehicle 100 in this application may include: road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, the vehicle 100 can be a vehicle, which is a vehicle in the broad sense, and can be a transportation vehicle (such as a commercial vehicle, a passenger car, a motorcycle, a flying car, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), agricultural equipment (such as a lawn mower, a harvester, etc.), amusement equipment, a toy vehicle, etc. The embodiments of this application do not specifically limit the type of vehicle. For another example, the vehicle 100 can be a vehicle such as an airplane or a ship.

[0084] The following takes the vehicle 100 as an example to illustrate the technical problems to be solved by this application and the technical solutions adopted.

[0085] As smart cars become more commonplace in daily life, users expect them and their associated devices to deliver a more comfortable, intelligent experience. Against this backdrop, digital key technology has emerged. Its primary function is to allow users to establish a connection with their vehicle using a mobile phone or other device, unlocking the doors when the phone approaches the vehicle from a distance, or locking the doors when the phone moves away from the vehicle. However, before implementing this technology, the vehicle must be calibrated based on received signal strength (RSSI). However, differences in wireless module and antenna design between different mobile phone models can lead to significant variations in received signal strength across vehicles, resulting in low calibration accuracy and severely impacting the user's seamless unlocking and locking experience.

[0086] For example, Figure 2 provides a calibration method. As shown in (a) of Figure 2, a car manufacturer can perform calibration using a dedicated calibration instrument. The calibration instrument can be equipped with a mobile terminal such as a mobile phone. The mobile phone first needs to connect to the vehicle via Bluetooth low energy (BLE). The calibration instrument is then moved to the vicinity of the BLE ranging nodes shown in (b) of Figure 2. The mobile phone obtains the current distance to the vehicle based on GPS positioning information near each BLE ranging node and notifies the vehicle of this distance. The vehicle then completes the calibration based on the received signal strength. This calibration method is very complex, and due to the differences in wireless modules and antenna designs of different mobile phones, the received signal strength of the vehicle varies greatly, resulting in low vehicle calibration accuracy.

[0087] For another example, FIG3 provides another calibration method, and method 300 may include the following steps.

[0088] S301, pairing the mobile phone and the vehicle.

[0089] Specifically, users can park their vehicle in an open area, keep the network between their mobile phone and vehicle open, and thus establish a connection between their mobile phone and vehicle.

[0090] S302: The mobile phone is 1 to 2.5 meters away from the vehicle's main driver's door.

[0091] Specifically, the user can hold the mobile phone, within a range of 1 to 2.5 meters from the main driver's door of the vehicle, and click the calibration operation on the mobile phone to complete the calibration of the mobile phone near the main driver's door.

[0092] S303: The mobile phone is 1 to 2.5 meters away from the passenger door of the vehicle.

[0093] Specifically, the user can hold the mobile phone, within a range of 1 to 2.5 meters from the passenger door of the vehicle, and click the calibration operation on the mobile phone to complete the calibration of the mobile phone near the passenger door.

[0094] S304: The mobile phone is 2 to 4.5 meters away from the vehicle trunk.

[0095] Specifically, the user can hold the mobile phone, within a range of 2 to 4.5 meters from the vehicle trunk, and click the calibration operation on the mobile phone to complete the calibration of the mobile phone near the vehicle trunk.

[0096] S305: The mobile phone key is calibrated successfully.

[0097] Specifically, after the mobile phone is calibrated around the vehicle, the user can use the mobile phone as a key to open or close the car door.

[0098] While this calibration method simplifies the calibration process, its rough approach makes it difficult to guarantee accuracy. For example, if a user calibrates within a range of 1 to 2.5 meters from the driver's door, the vehicle may not be able to unlock or lock automatically if the user moves outside this range.

[0099] The embodiments of the present application provide a calibration method, device, and system that can make vehicle calibration more accurate, thereby improving the user experience of using digital key technology for contactless unlocking and locking.

[0100] Before introducing the calibration method provided in the embodiment of the present application, the system architecture to which the calibration method is applicable is first introduced.

[0101] FIG4 is a system architecture applicable to the calibration method provided in an embodiment of the present application.

[0102] As shown in Figure 4, the system architecture may include a mobile phone and a vehicle; the mobile phone may include: a calibration application (APP) and Bluetooth hardware, wherein the calibration APP may have a user interface (UI) display and interaction capabilities, and the Bluetooth hardware has Bluetooth positioning capabilities. The vehicle may include: a calibration service module, a Bluetooth controller, an ultrasonic sensor (USS) controller, USS hardware and Bluetooth hardware. Among them, the Bluetooth controller and Bluetooth hardware can be collectively referred to as a Bluetooth positioning system, which is responsible for pairing with the mobile phone and establishing a connection, and the USS controller and USS hardware can be collectively referred to as an ultrasonic positioning system, which is used to receive signals sent by the mobile phone and perform ranging. The calibration service module is responsible for calculating and managing calibration strategies, as well as coordinating and managing the Bluetooth and ultrasonic positioning systems to work together to complete calibration. The calibration module may be located in the digital key system 140 in the vehicle 100.

[0103] After installing the calibration APP, users can use their own mobile phones (can be various models) to establish a connection with the vehicle and complete high-precision calibration according to the prompts on the mobile phone interface.

[0104] It should be understood that in the embodiment of the present application, the mobile phone can also be replaced with other mobile terminals for calibration. The mobile terminal can be a tablet computer, a watch, a wearable device or other terminal device with Bluetooth connection capability.

[0105] FIG5 is a schematic flowchart of a calibration method provided in an embodiment of the present application. Method 500 can be applied to the system architecture of FIG4 . Method 500 can include the following steps.

[0106] S501: A mobile terminal receives a first message sent by a vehicle.

[0107] The first message includes location information of at least one first calibration point.

[0108] Exemplarily, the mobile terminal may be a terminal device with Bluetooth connection capability, such as a tablet computer, a mobile phone, a smart watch, or a wearable device.

[0109] In one embodiment, before step S501, the method further includes: the mobile terminal sending a first instruction message to the vehicle, the first instruction message being used to request the vehicle to initiate calibration. This can prevent the vehicle from unnecessarily pushing the location information of the calibration point, making it easier for the user to control the entire calibration process.

[0110] S502: The mobile terminal is prompted to move to at least one first calibration point according to the first message.

[0111] Optionally, the mobile terminal may prompt the user to move to at least one first calibration point through a display screen or voice.

[0112] In one embodiment, the first message may include a calibrated route, comprising at least one first calibration point and a recommended route between a second calibration point and a third calibration point, where the second calibration point and the third calibration point are calibration points included in the at least one first calibration point. After receiving the calibrated route, the mobile terminal may display the calibrated route. In this way, the user can move from the second calibration point to the third calibration point according to the instructions on the calibrated route, thereby completing the calibration of the at least one first calibration point.

[0113] Among them, the second calibration point and the third calibration point can both be the first calibration point, and the recommended route between the second calibration point and the third calibration point can be a straight line, a broken line, a curve, etc., which is not limited in this embodiment of the present application.

[0134] S602: The mobile terminal starts calibration.

[0135] Specifically, the user can operate on the calibration APP of the mobile terminal to decide whether to start calibration.

[0136] S603: The vehicle pushes the calibration strategy to the mobile terminal.

[0137] Specifically, the vehicle may push the calibration strategy to the mobile terminal via the Bluetooth channel through the Bluetooth master node. The calibration strategy may be the first message in method 500 .

[0138] Optionally, the calibration strategy may include location information of one or more calibration points.

[0139] S604: The vehicle performs USS ranging.

[0145] Then, steps S604 to S606 are repeated to complete the calibration of the remaining points, that is, the user can move to the next calibration point according to the UI prompt on the mobile terminal until the calibration is completed.

[0146] In this embodiment of the present application, after starting calibration, the vehicle can perform distance measurement and push the distance measurement results and the location information of the calibration points to the mobile terminal, which then prompts the user to move to the corresponding calibration points to complete the calibration.

This interface prompts the user to park the vehicle in an open area and ensure smooth network connectivity between the vehicle and the phone. When the phone detects a user clicking control 701, the phone can pair with the vehicle. After pairing is complete, the phone displays the GUI shown in Figure 7 (b), which can display the location information of different calibration points and the phone's location information. The phone's location information can be sent to the phone after the vehicle takes measurements, or it can be obtained by the phone itself using GPS positioning information. The location information of different calibration points can be pre-set by the vehicle and sent to the phone. When the phone detects a user clicking control 702, the phone displays the GUI shown in Figure 7 (c), which prompts the user to move to any calibration point. Optionally, this interface can also display the distance and angle between the phone's current location and the different calibration points. The user can move to any calibration point according to the prompts on this interface. As shown in Figure 7 (d), when the user moves to the first calibration point, the phone can prompt the user to move to the first calibration point. At this point, the vehicle can record the signal reception strength of the mobile phone at the first calibration point based on the first signal sent by the mobile phone, and complete the calibration of the first calibration point. When the first calibration point is calibrated, the mobile phone can display a GUI as shown in (e) of Figure 7, which is used to prompt the user that the first calibration point has been calibrated and ask the user to move to the next calibration point. At the same time, after the first calibration point is calibrated, the first calibration point can be marked with a specific color (for example, green, black, etc.) on the UI interface of the mobile phone. When the user moves to the next calibration point (for example, the second calibration point), the mobile phone can display a GUI as shown in (f) of Figure 7, which is used to prompt the user that the second calibration point has been moved to and not to move. At this point, the vehicle can record the signal reception strength of the mobile phone at the second calibration point based on the first signal sent by the mobile phone, and complete the calibration of the second calibration point. When the second calibration point is calibrated, the mobile phone can display a GUI as shown in (g) of Figure 7, which is used to prompt the user that the second calibration point has been calibrated and ask the user to move to the next calibration point, thus completing the calibration of the other calibration points.

When the phone detects a user clicking control 801, the phone may display the GUI shown in (b) of Figure 8. This GUI displays the location information of different calibration points, the phone's location information, and the calibration route. This interface prompts the user to move to the nearest calibration point, number 1. The phone's location information may be sent to the phone after the vehicle performs a measurement, or it may be obtained by the phone itself using GPS positioning information. The location information of different calibration points and the calibration route may be pre-set or planned by the vehicle and sent to the phone. When the phone detects a user clicking control 802, the phone may display the GUI shown in (c) of Figure 8. This GUI prompts the user to move to the location of calibration point 1 and advise them not to move. The vehicle can record the signal reception strength and / or quality of the phone at calibration point 1 based on the first signal sent by the phone and complete the calibration of calibration point 1. When calibration point No. 1 is calibrated, the mobile phone may display a GUI as shown in (d) in FIG8 , which prompts the user that calibration point No. 1 has been calibrated and asks the user to move to calibration point No. 2 or No. 14 according to the moving route. At the same time, calibration point No. 1 can be marked with a specific color (e.g., green, black, etc.) on the UI interface of the mobile phone. When the user moves to calibration point No. 2 along the calibration route, the mobile phone may display a GUI as shown in (e) in FIG8 , which prompts the user that the user has moved to the location of calibration point No. 2 and asks the user not to move. At the same time, the vehicle can record the signal reception strength and / or quality of the mobile phone at calibration point No. 2 based on the first signal sent by the mobile phone and complete the calibration of calibration point No. 2. When calibration point No. 2 is calibrated, the mobile phone can display the GUI shown in (f) in Figure 8. The GUI is used to prompt the user that calibration point No. 2 has been calibrated, and the user is asked to continue to complete the calibration of the remaining calibration points according to the calibration route. When all calibration points are calibrated, the mobile phone can display the GUI shown in (g) in Figure 8. The GUI informs the user that all calibration points have been calibrated. At this time, the user can click control 803 to exit the calibration interface.
