[0061] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0062] Digital keys used in the automotive field are often also called virtual keys. This new vehicle control technology is increasingly becoming a standard configuration for vehicles. In practical applications, digital keys mainly use wireless communication technologies such as BLE (Bluetooth Low Energy), UWB (Ultra Wide Band) and NFC (Near-Field Communication), so that users can use smartphones, tablets or wearable devices such as smart watches and smart bracelets equipped with BLE, UWB or NFC functional modules to perform related control operations such as unlocking, locking and starting the vehicle doors. Furthermore, the digital key function can also be integrated into the physical key of the vehicle, so that the physical key of the car can realize the same vehicle control function as the aforementioned smartphone or wearable device. In the present invention, the physical key that can participate in the control of the vehicle access control system and various forms of devices such as smartphones and wearable devices are collectively referred to as car key terminals, and this definition is used in subsequent embodiments.

[0063] It is understandable that in actual use, a matching relationship should be established between the vehicle and the car key terminal (specifically, it can be set by the manufacturer or seller before the vehicle is delivered to the user, or by the user in accordance with the user manual, which will not be detailed here) to ensure that the vehicle can only be controlled by the car key terminal that matches it. Specifically, the vehicle is equipped with a vehicle-side digital key controller, and the vehicle-side digital key controller establishes the aforementioned matching relationship with the car key terminal. The vehicle-side digital key controller and the car key terminal cooperate with each other to realize the relevant functions of the vehicle access control system.

[0064] Furthermore, on the basis of the vehicle-side digital key controller, the vehicle is also equipped with a vehicle control unit (VCU), also known as a vehicle controller. The vehicle control unit is the core control component of the entire vehicle. By collecting accelerator pedal signals, brake pedal signals and other component signals and making corresponding judgments, it controls the actions of the lower-level component controllers to drive the car normally. At the same time, as the command and management center of the car, the main functions of the vehicle control unit also include: driving torque control, optimal control of braking energy, energy management of the whole vehicle, maintenance and management of the communication network, diagnosis and processing of faults, vehicle status monitoring, etc. In short, the vehicle control unit plays a role in controlling the operation of the vehicle. In order to reduce vehicle power consumption, the vehicle control unit will enter sleep mode when the vehicle is turned off and the doors are locked.

[0065] Combined with the actual application requirements, it can be seen that the relative position relationship between the vehicle and the car key terminal plays a vital role in the realization of the digital key function. For example, when the user is away from the vehicle, the car-side digital key controller needs to lock the vehicle. Correspondingly, when the user is close to the vehicle and the distance between the vehicle and the vehicle is within a certain distance range, the car-side digital key controller unlocks the vehicle. In the prior art, the positioning of the car key terminal by the car-side digital key controller is usually based on wireless signals. Taking the digital key implemented based on BLE technology as an example, the car key terminal broadcasts a Bluetooth signal outward. Since the RSSI (Received Signal Strength Indicator) of the Bluetooth signal will gradually weaken as the propagation distance increases, the car-side digital key controller can determine the distance between the car key terminal and the vehicle based on the RSSI of the obtained Bluetooth signal. Of course, in actual applications, vehicles usually have multiple receiving antennas to analyze the RSSI of the Bluetooth signal of the car key terminal from multiple angles to further improve the positioning accuracy of the car key terminal. As for the digital keys implemented based on other wireless communication technologies, they will not be expanded here one by one.

[0066] Based on the above, see Figure 1 , Figure 1This is a schematic diagram of an application scenario of a digital car key in the prior art. In combination with the actual application needs of users, different control areas can be divided around the vehicle, and corresponding access control functions can be implemented when the user is in different control areas. Figure 1 In the scenario shown, the control area is divided into the starting area S1, the unlocking area S2 and the locking area S3. Based on this range division, when the user approaches the vehicle from a remote end with the car key terminal, when the user enters the unlocking area S2, the vehicle-side digital key controller automatically unlocks the door. Further, when the user enters the starting area S1, that is, enters the vehicle cockpit, the user can start the vehicle. Correspondingly, when the user moves away from the vehicle, once the user exceeds the locking area S3, the vehicle-side digital key controller automatically locks the door to lock the car. Of course, in actual applications, more abundant access control functions can also be provided to users, such as further dividing the welcome area. When the user enters the welcome area, the vehicle's welcome lights are turned on, the seat heating is automatically turned on, etc., which will not be elaborated here.

[0067] It should be noted that Figure 1 In the application scenario shown, S4 shows the communication connection range between the vehicle-side digital key controller and the car key terminal. The car key terminal can only establish an effective communication connection relationship with the vehicle-side digital key controller when it is within the communication connection range S4. Of course, this also means that once the car key terminal is outside the communication connection range, an effective connection cannot be established between the vehicle and the car key terminal. As mentioned above, the car key terminal includes a variety of specific implementation methods such as car physical keys and smart phones. Based on this, the communication connection range between the vehicle-side digital key controller and the car key terminal can also be customized according to the specific form of the car key terminal. For example, the vehicle-side digital key controller and the car physical key are configured with a first communication connection range, and correspondingly, the second communication connection range is configured with the smart phone. As for the size relationship between the first communication connection range and the second communication connection range coverage area, it can be set in combination with actual application requirements and will not be repeated here. Furthermore, the communication connection ranges corresponding to digital keys implemented based on different technologies and different car models are often different. The present invention does not limit the specific setting of the communication connection range.

[0068] The inventors have found that in actual applications, if the car key terminal is within the above-mentioned communication connection range for a long time, for example, the user stays near the vehicle for a long time while holding the car key terminal, or the vehicle is close to the location where the user places the car key terminal, the car key terminal is connected to the vehicle for a long time, and the vehicle-side digital key controller will continue to locate the car key terminal, which will inevitably cause excessive power consumption of the vehicle and the car key terminal, and poor endurance performance, affecting the user's experience.

[0069] In order to solve this technical problem, the present invention provides a car digital key system, which specifically includes a car key terminal and a vehicle, wherein the car key terminal includes at least one first terminal and / or at least one second terminal, and the vehicle is provided with a vehicle-side digital key controller and a vehicle controller. Of course, the first terminal and the second terminal are matched with the vehicle-side digital key controller, and the first terminal and the second terminal can both realize relevant control of the vehicle. Furthermore, the vehicle-side digital key controller is configured with a first communication connection range corresponding to the first terminal, and when the first terminal is within the first communication connection range, a communication connection can be established with the vehicle-side digital key controller. Correspondingly, the vehicle-side digital key controller is configured with a second communication connection range corresponding to the second terminal, and when the second terminal is within the second communication connection range, a communication connection can be established with the vehicle-side digital key controller. In practical applications, the coverage area of ​​the first communication connection range and the second communication connection range may be the same or different, and the present invention does not limit this.

[0070] Furthermore, the first terminal may be a physical car key, and the second terminal may be a user terminal, wherein the user terminal includes a smart phone, a tablet computer, or a wearable device, such as a smart watch, a smart bracelet, etc. Figure 2 In the embodiment shown, the car key terminal 100 includes a user terminal 101 and a car physical key 102, and the vehicle 200 is provided with a vehicle-side digital key controller, through which the vehicle-side digital key controller can realize corresponding control of the car key terminal 100 and the vehicle 200 access control system. It can be understood that in Figure 2 In the illustrated scenario, the user terminal 101 is presented as a smartphone, and the user can issue corresponding control instructions to the vehicle 200 by operating the smartphone, such as unlocking the door, etc. The vehicle control functions that can be implemented by the first terminal and the second terminal are different. In actual applications, the vehicle control functions of the physical car key are usually less than those of the user terminal. For example, the physical car key does not have functions such as remote starting and stopping of the vehicle and remote lifting of windows. This is related to the implementation methods of different car key terminals and will not be described in detail here. It should be noted that in the subsequent embodiments, the positioning method provided by the present invention is introduced by taking the first terminal as the physical car key and the second terminal as the user terminal as an example.

[0071] The automobile digital key system provided by the present invention, when the vehicle controller of the vehicle enters the sleep mode and the automobile key terminal is within the communication connection range, the vehicle monitors the first wake-up event that causes the vehicle controller to exit the sleep mode, and enters the stay mode if the first wake-up event is not detected within a preset time period. Since the power consumption corresponding to the stay mode is lower than the power consumption corresponding to the continuous positioning of the automobile key terminal by the vehicle-side digital key controller, the power consumption of the vehicle can be reduced, the endurance performance can be improved, and the user experience can be improved.

[0072] Correspondingly, for the car key terminal, the power consumption can be reduced according to the first indication information of the vehicle-side digital key controller. Therefore, this method can also reduce the operating power consumption of the car key terminal when it is within the communication connection range, and can also improve the endurance performance.

[0073] Furthermore, the present invention provides a method for locating a car key terminal, which is applied to the car digital key system provided in the above embodiment, and is specifically applied to a vehicle-side digital key controller of a vehicle. Figure 3 As shown, the process of the automobile key terminal positioning method provided in this embodiment may include:

[0074] S100: When a vehicle controller of a target vehicle enters a sleep mode and the vehicle key terminal is within a communication connection range, monitor a first wake-up event that causes the vehicle controller to exit the sleep mode.

[0075] In this embodiment and subsequent embodiments, the target vehicle refers to a vehicle that matches the car key terminal. Of course, as mentioned above, a communication connection range is configured between the car key terminal and the vehicle-side digital key controller of the target vehicle. When the car key terminal enters the communication connection range, an effective communication connection is established with the vehicle-side digital key controller set for the target vehicle.

[0076] Combination Figure 1 As shown, after turning off the vehicle, the user carries the car key terminal and moves away from the target vehicle. During this process, although the target vehicle has been turned off, the vehicle-side digital key controller set by the target vehicle itself is still in operation and continues to locate the car key terminal. When the car key terminal is identified as being within the locking area, the target vehicle locks the door and the vehicle controller enters sleep mode. It should be noted that after the vehicle controller enters sleep mode, since the car key terminal is still within the communication connection range, the vehicle-side digital key controller still establishes an effective communication connection with the car key terminal, and the vehicle-side digital key controller continues to locate the car key terminal.

[0077] Furthermore, the first wake-up event mainly refers to an event that can wake up the vehicle controller and make the vehicle controller exit the sleep mode. In a possible implementation, the first wake-up event includes at least one of receiving a key search request, receiving a control instruction that can wake up the target vehicle, the vehicle key terminal entering a preset range for waking up the target vehicle, and other vehicle key terminals other than the vehicle key terminal entering a communication connection range.

[0078] Among them, after the vehicle controller of the target vehicle enters the sleep mode, if any user touches the vehicle door handle, such as pulling up the vehicle door handle to try to open the door, or triggering the unlock button set on the door handle, etc., it can trigger a key search request. The target vehicle responds to the key search request and exits the sleep mode.

[0079] There may be many control instructions that can wake up the target vehicle in actual applications, such as unlocking the door, starting the vehicle, starting the seat ventilation or heating function, turning on the air conditioner, etc. For different vehicle configurations, the control instructions that can wake up the vehicle will be different. For example, the control instructions can also include NFC unlocking instructions, etc. In this application, any control instructions that can wake up the target vehicle are optional and also fall within the scope of protection of the present invention.

[0080] Combination Figure 1 As shown, in a possible application scenario, after locking the vehicle, the user moves away from the vehicle, and returns to the target vehicle, that is, moves closer to the target vehicle, without exceeding the communication connection range between the aforementioned vehicle-side digital key controller and the car key terminal. In this case, the user may enter the welcome area, unlocking area, etc., which can wake up the target vehicle. Based on the above content, it can be seen that when the user is within such a preset range, the target vehicle can be woken up, the target vehicle exits the sleep mode, and further executes the response function corresponding to the user's location. It can be understood that the preset range for waking up the target vehicle described in this embodiment is smaller than the preconfigured communication connection range.

[0081] In another possible embodiment, there are multiple car key terminals matching the target vehicle. After the target vehicle enters sleep mode, if other matching car key terminals enter the communication connection range, they can also establish a communication connection with the vehicle-side digital key controller to wake up the target vehicle.

[0082] Based on the above content, when the vehicle controller of the target vehicle enters the sleep mode and the car key terminal is still within the communication connection range, the vehicle-side digital key controller monitors the first wake-up event that can cause the vehicle controller to exit the sleep mode.

[0083] In a possible implementation, monitoring the first wake-up event is defined as a retention transition mode, and the vehicle controller of the target vehicle enters a sleep mode and the car key terminal is within the aforementioned communication connection range as a trigger condition for the vehicle-side digital key controller to enter the retention transition mode, that is, when the vehicle controller of the target vehicle enters a sleep mode and the car key terminal is within the aforementioned communication connection range, the vehicle-side digital key controller enters the retention transition mode and monitors the first wake-up event. It should be noted that after the vehicle-side digital key controller enters the retention transition mode, the vehicle-side digital key controller still continues to locate the car key terminal.

[0084] S101, determining whether a first wake-up event is not detected within a preset time period, and if so, executing S102.

[0085] In combination with the foregoing, the first wake-up event mainly refers to an event that can cause the vehicle controller of the target vehicle to exit sleep mode, such as any key search request triggered by the user touching the vehicle door handle, or a control command issued by the user through the user terminal to unlock the door, start the vehicle, start the seat ventilation or heating function, turn on the air conditioner, etc.

[0086] In some embodiments, the first wake-up event is closely related to the user's intention to use the car. When the car key terminal is in the communication connection range, if the first wake-up event does not occur for a long time, it can be said that the possibility of the user using the target vehicle again is extremely low, that is, the user has no intention to use the car. On the contrary, if the first wake-up event is detected within the preset time, it can be considered that the user has the intention to use the car. Therefore, whether to enter the stay mode can be determined based on whether the first wake-up event is detected within the preset time.

[0087] Furthermore, as mentioned above, the car key terminal includes at least one of a user terminal and a physical car key. Therefore, in actual applications, there may be three situations in which a user carries a car key terminal: first, the user only carries the user terminal; second, the user only carries the physical car key; third, the user carries both the user terminal and the physical car key.

[0088] In a possible implementation, if the car key terminal is a physical car key or a user terminal, it can be determined whether to enter the stay mode according to whether the first wake-up event is detected within a preset time period.

[0089] In another possible implementation, if the car key terminal includes both a physical car key and a user terminal, it is necessary to determine whether to enter the stay mode based on whether the first wake-up event is detected within a preset time period and the connection status between the physical car key and the target vehicle.

[0090] When the user carries different car key terminals, the differences in the specific implementation methods for determining whether to enter the stay mode will be introduced in the subsequent content in combination with the specific situation, and will not be described in detail here. However, it should be emphasized that no matter which of the above situations the car key terminal is, the monitoring result of the first wake-up event is used as the key basis for determining whether to enter the stay mode.

[0091] Based on the above content, if the first wake-up event is not detected within the preset time, the subsequent S102 is executed. On the contrary, if the first wake-up event is detected within the preset time, the current control process can be exited, the positioning of the car key terminal is maintained, and the user's control instructions are responded to according to the existing control logic.

[0092] S102, entering the retention mode.

[0093] First of all, it should be noted that in the car key terminal positioning method provided by the present invention, the power consumption corresponding to the retention mode is lower than the power consumption corresponding to the continuous positioning of the car key terminal by the vehicle-side digital key controller. Therefore, after the vehicle-side digital key controller enters the retention mode, the overall operating power consumption of the vehicle can be effectively reduced.

[0094] In one possible implementation, the vehicle-side digital key controller disconnects the communication connection with the vehicle key terminal. In another possible implementation, the vehicle-side digital key controller stops locating the vehicle key terminal. As for how to select the implementation method of the above-mentioned retention mode in actual application, it needs to be determined in combination with the specific form of the vehicle key terminal, which will be specifically expanded in the subsequent content and will not be described in detail here.

[0095] Furthermore, when the vehicle-side digital key controller enters the stay mode, it can also send a first indication message to the car key terminal, and the first indication message can instruct the car key terminal to reduce power consumption. For the car key terminal, when the vehicle controller enters the sleep mode and the car key terminal is within the communication connection range, after obtaining the first indication message, the power consumption is reduced according to the first indication message, which can effectively improve the endurance of the terminal itself. When facing different car key terminals, the specific form of the first indication message will be different, which will be explained in the subsequent content in conjunction with the specific embodiment, and will not be described in detail here.

[0096] To sum up, through the car key terminal positioning method provided by this embodiment, when the vehicle controller enters the sleep mode and the car key terminal is within the communication connection range between the vehicle-side digital key controller and the car key terminal, the first wake-up event that causes the vehicle controller of the target vehicle to exit the sleep mode is monitored, and when the first wake-up event is not detected within the preset time, the stay mode is entered. Since the power consumption corresponding to the stay mode is lower than the power consumption corresponding to the continuous positioning of the car key terminal by the vehicle-side digital key controller, the power consumption of the vehicle can be reduced, the endurance performance can be improved, and the user experience can be improved.

[0097] For the car key terminal, the power consumption can be reduced according to the first indication information of the vehicle-side digital key controller. Therefore, this method can also reduce the operating power consumption of the car key terminal when it is within the communication connection range, and can also improve the endurance performance.

[0098] Furthermore, after the target vehicle enters the stay mode, the vehicle-side digital key controller can also respond to the received second wake-up event to exit the stay mode and restart positioning the vehicle key terminal.

[0099] Among them, the second wake-up event described in this embodiment includes at least one of receiving a key search request, receiving a control instruction to wake up the target vehicle, and other car key terminals other than the car key terminal entering the communication connection range.

[0100] It should be noted that, compared with the aforementioned first wake-up event, the second wake-up event does not include: the car key terminal enters the preset range of the target vehicle for waking up. The reason is that the target vehicle has stopped locating the car key terminal, so the target vehicle does not know the specific location of the car key terminal at this time. Therefore, even if the user brings the car key terminal close to the target vehicle again and enters the preset range, the target vehicle will not be awakened, and the welcome function, automatic unlocking function, etc. of the target vehicle will be invalid in this case.

[0101] It should also be noted that although the car key terminal will not wake up the target vehicle when it enters the preset range for waking up the target vehicle, the car key terminal is still within the communication connection range, and the vehicle-side digital key controller of the target vehicle still establishes a communication connection with the car key terminal. Based on this, the user can still send control instructions to the target vehicle through the car key terminal to wake up the target vehicle. Therefore, this method does not affect the user's normal use of the target vehicle, and naturally does not affect the user's experience of use.

[0102] The following describes the vehicle key terminal positioning method provided by the present invention in conjunction with the specific structure of the vehicle key terminal.

[0103] In a possible implementation, the car key terminal includes a physical car key and a user terminal, that is, the user carries both the physical car key and the user terminal. In this case, see Figure 4 , Figure 4 The process of the vehicle key terminal positioning method provided in the illustrated embodiment may include:

[0104] S200: When the vehicle controller enters the sleep mode and the car key terminal is within the communication connection range, the vehicle-side digital key controller monitors the first wake-up event that causes the vehicle controller to exit the sleep mode.

[0105] As mentioned above, in one possible implementation, the vehicle-side digital key controller and the vehicle physical key are configured with a first communication connection range, and at the same time, the vehicle-side digital key controller and the user terminal are configured with a second communication connection range. In this case, the vehicle key terminal mentioned in this embodiment is within the communication connection range, which specifically means that the vehicle physical key is within the first communication connection range, and correspondingly, the user terminal is within the second communication connection range. In this case, the vehicle physical key and the user terminal can be respectively communicated and connected with the vehicle-side digital key controller.

[0106] For other contents related to this step, please refer to Figure 3 The implementation of S100 in the illustrated embodiment will not be repeated here.

[0107] S201: When the duration of monitoring the first wake-up event reaches a first duration, the vehicle-side digital key controller sends a disconnection request to the vehicle physical key.

[0108] In a possible implementation, after the vehicle controller of the target vehicle enters the sleep mode, the vehicle-side digital key controller in the target vehicle is still in operation, and the vehicle-side digital key controller statistically monitors the duration of the first wake-up event, and sends a disconnection request to the physical key of the vehicle when the duration reaches the first duration. For example, when the digital key is implemented based on Bluetooth technology, the disconnection request can specifically be a Bluetooth disconnection request.

[0109] It can be understood that, as mentioned above, if the first wake-up event is detected within the first time range, the vehicle-side digital key controller can exit the current control process, maintain the positioning of the vehicle physical key and the user terminal, and respond to the user's control instructions according to the existing control logic. Once the first wake-up event is detected, the timing will be stopped immediately. Therefore, the duration mentioned in the present invention refers to the duration during which the first wake-up event is not detected. If the first wake-up event is detected before the duration reaches the first duration, the timing will be stopped and the statistical result of the duration will be cleared to zero.

[0110] It should be noted that the specific value of the first duration needs to be determined comprehensively in combination with actual control requirements and user usage habits, and the present invention does not limit the specific value of the first duration.

[0111] In a possible implementation, the first duration can be set by the user according to factors such as the user's actual situation and usage habits.

[0112] S202: When the physical key of the automobile is within the communication connection range, a disconnection request is obtained.

[0113] When in the communication connection range, the physical car key and the target vehicle still have an effective connection relationship, and the physical car key obtains a disconnection request from the target vehicle.

[0114] S203: The vehicle physical key responds to the disconnection request and determines the current state.

[0115] The physical car key first determines its current state based on the received disconnection request. Based on the actual usage scenarios of the physical car key, the state of the physical car key mainly includes a static state and a running state. It is understandable that if the user moves with the physical car key, the physical car key is in motion, and correspondingly, if the user places the physical car key somewhere, the physical car key is in a static state.

[0116] In a possible implementation, the physical car key is equipped with an inertial measurement unit (IMU). Based on the basic principle of IMU, it can be known that IMU can output multiple acceleration signals and multiple heading angle signals during operation. The controller in the physical car key can determine the current state of the physical car key based on the various signals fed back by the IMU. As for the specific determination process of the current state of the physical car key, it can be implemented with reference to relevant technologies and will not be expanded here.

[0117] S204: Currently in a stationary state, the physical car key stops sending broadcast signals and disconnects the communication connection with the target vehicle.

[0118] If it is determined that the vehicle is currently in a stationary state, the physical key of the vehicle stops sending a broadcast signal for establishing a communication connection with the target vehicle, and disconnects the communication connection with the target vehicle (ie, the vehicle-side digital key controller). At this point, the target vehicle disconnects the communication connection with the physical key of the vehicle.

[0119] In one possible implementation, the digital key is implemented based on BLE technology. In this case, since the broadcast state saves more power than the scanning state, and the physical car key is powered by a small battery with limited endurance, the physical car key usually sends the broadcast signal, and the target vehicle scans the broadcast signal. If the user carries the physical car key around, that is, the physical car key is in motion, the user is likely to have the intention to use the car. Therefore, the physical car key combines its own signal to determine whether to disconnect from the target vehicle, which is more in line with the actual application scenario.

[0120] It should be noted that if the physical car key is determined to be in motion, it will not disconnect from the target vehicle. In this case, the physical car key continues to monitor its own motion state until it is in a stationary state, and then disconnects from the target vehicle. Of course, in a possible application scenario, the physical car key is always in motion. In this case, it is impossible to disconnect from the target vehicle, and it is naturally difficult to reduce the power consumption of the target vehicle and the car key terminal. Of course, if the physical car key enters the motion state again after being in a stationary state, the physical car key will send a broadcast signal again.

[0121] S205: When the duration of the monitoring first wake-up event reaches the second duration and the physical car key is not in communication connection with the target vehicle, the vehicle-side digital key controller stops locating the user terminal.

[0122] When processing the connection relationship with the physical key of the car, the first wake-up event is still monitored, and the corresponding duration is still being counted, that is, the duration of the first wake-up event not being monitored is still increasing. Based on this, if the physical key of the car disconnects the communication connection with the target vehicle after the above steps, and the duration is greater than or equal to the second duration, the vehicle-side digital key controller stops locating the user terminal.

[0123] It should be noted that the aforementioned first duration is shorter than the second duration in this step. The reason for this setting is that compared with the battery life of user terminals such as smartphones, the battery life of physical car keys is shorter and more sensitive to power consumption. Therefore, setting the first duration shorter is conducive to disconnecting the physical car key from the target vehicle as soon as possible and reducing power consumption.

[0124] On the contrary, if the first wake-up event is detected within the second time period or the physical car key is still in communication with the target vehicle, the vehicle-side digital key controller continues to locate the user terminal. It is understandable that if the first wake-up event is detected within the second time period, the target vehicle exits the sleep mode and also exits the current control process of this method until the next control cycle starts when the vehicle controller enters the sleep mode next time. Correspondingly, if the physical car key is still in communication with the vehicle-side digital key controller, it means that the physical car key is still in motion. For the vehicle-side digital key controller, it is necessary to wait for the physical car key to actively disconnect the communication connection with the vehicle-side digital key controller according to the aforementioned steps S201 to S204.

[0125] It should be noted that, when the car key terminal includes both the car physical key and the user terminal, the connection status between the car physical key and the vehicle-side digital key controller is used as a judgment condition for whether the positioning of the user terminal can be stopped. The reason is: as mentioned above, after the vehicle controller enters the sleep mode, the vehicle-side digital key controller is still in operation and will still respond to the broadcast signal of the car physical key. Therefore, when the car physical key is in motion, that is, the broadcast signal is not actively stopped, even if the vehicle-side digital key controller actively disconnects the connection with the car physical key, the vehicle-side digital key controller may still respond to the broadcast signal of the car physical key and establish a connection with the car physical key again, and then locate other devices around the vehicle again, which cannot achieve the purpose of reducing the power consumption of the target vehicle.

[0126] Based on the above content, the vehicle-side digital key controller stops locating the user terminal, thereby reducing the power consumption caused by continuous positioning of the user terminal, which helps to increase the endurance of the target vehicle.

[0127] S206. The vehicle-side digital key controller sends a first notification message to the user terminal.

[0128] In this embodiment, the aforementioned first indication information includes first notification information, and the first notification information is mainly used to notify the user terminal that the target vehicle has stopped continuously positioning the user terminal, and the user terminal can operate in a preset low power consumption mode.

[0129] It should be noted that in the present application, when the vehicle-side digital key controller stops locating the user terminal, it is still in communication connection with the user terminal. Therefore, stopping locating the user terminal will not affect the sending of the first notification information.

[0130] S207: The user terminal operates in a preset low power consumption mode in response to the first notification information.

[0131] After the user terminal obtains the first notification information, it can respond to the first notification information and operate in a preset low-power mode. Taking the digital key based on BLE technology as an example, the user terminal can increase the connection interval of the Bluetooth connection with the target vehicle, and can also reduce the broadcast frequency of the Bluetooth broadcast signal. Of course, for digital keys based on other technologies, the corresponding low-power mode can be set based on its own technical specific settings. It will not be described in detail here. Under the premise of not exceeding the core idea of ​​the present invention, it also belongs to the scope of protection of the present invention.

[0132] It should be noted that, in this embodiment, after the target vehicle is disconnected from the physical car key and stops locating the user terminal, it can still respond to the aforementioned second wake-up event, exit the sleep mode and restart locating the car key terminal.

[0133] To sum up, the car key terminal positioning method provided in the embodiment of the present invention can reduce the power consumption of the target vehicle, the car physical key and the user terminal, improve the cruising performance of the target vehicle, the car physical key and the user terminal, and help improve the user experience when the car key terminal includes both the car physical key and the user terminal.

[0134] Furthermore, after the target vehicle terminal stops locating the car key terminal, it does not affect the user's normal use of the target vehicle, and the user can still wake up the target vehicle by triggering the aforementioned second wake-up event.

[0135] Furthermore, for the user terminal, the user terminal enters a preset low-power mode, which is essentially that the application used to implement the car key terminal positioning method provided in the present application runs in a preset low-power mode. For example, after receiving the first notification information, the connection interval of the Bluetooth connection with the target vehicle is increased or the broadcast frequency of the Bluetooth broadcast signal is reduced. Based on this, the power consumption and hardware resource occupation of the application on the user terminal itself can be reduced, thereby reducing the possibility of the application being forcibly uninstalled because it is judged as a malicious program, thereby improving the survival rate of the application.

[0136] In another possible implementation, the car key terminal includes only the car physical key, that is, the car physical key is within the first communication connection range corresponding to the car physical key configured by the vehicle-side digital key controller. In this case, see Figure 5 , Figure 5 The process of the vehicle key terminal positioning method provided in the illustrated embodiment may include:

[0137] S300: When the vehicle controller enters the sleep mode and the physical key of the vehicle is within the first communication connection range, the vehicle-side digital key controller monitors the first wake-up event.

[0138] In a possible implementation, S300 may refer to Figure 3 The implementation of S100 in the illustrated embodiment will not be repeated here.

[0139] S301: If the duration of monitoring the first wake-up event reaches a first duration, the vehicle-side digital key controller sends a disconnection request to the vehicle physical key.

[0140] Since the car key terminal in this embodiment only includes the physical car key, the aforementioned first indication information is specifically a disconnection request, that is, when the duration of the first wake-up event is not detected to reach the first duration, a disconnection request is sent to the physical car key. On the contrary, if the first wake-up event is detected within the first duration, it is determined that the user has a need to use the vehicle, and at the same time, the duration is reset to zero, and the control process of the next control cycle is restarted. As for other relevant details of implementing this step, please refer to the aforementioned content and will not be repeated here.

[0141] As for the specific implementation process of the vehicle-side digital key controller sending a disconnection request to the vehicle physical key, please refer to Figure 4 S201 is implemented in the illustrated embodiment and will not be repeated here.

[0142] S302: When the vehicle is within the communication connection range, the vehicle physical key obtains a disconnection request.

[0143] In a possible implementation, S302 may refer to Figure 4 S202 is implemented in the illustrated embodiment and will not be repeated here.

[0144] S303: In response to the disconnection request, the vehicle physical key determines the current state.

[0145] In a possible implementation, S303 may refer to Figure 4 S203 is implemented in the illustrated embodiment and will not be repeated here.

[0146] S304: Currently in a stationary state, the physical car key stops sending broadcast signals and disconnects the communication connection with the target vehicle.

[0147] In a possible implementation, S304 may refer to Figure 4 S204 is implemented in the illustrated embodiment and will not be repeated here.

[0148] Furthermore, after the physical car key stops sending broadcast signals and disconnects the communication connection with the vehicle-side digital key controller, it continues to monitor the state of the physical car key. If the state of the physical car key changes from a stationary state to a moving state, the physical car key sends the broadcast signal again. In a possible implementation, the monitoring of the state of the physical car key is achieved based on the acceleration signal and the angular signal fed back by the IMU configured inside the key.

[0149] To sum up, when only the physical car key is within the first communication connection range, if the duration of the first wake-up event is not detected to reach the first duration, a disconnection request can be sent to the physical car key, and the physical car key actively disconnects the communication connection with the target vehicle, the target vehicle stops locating the physical car key, and the physical car key stops sending broadcast signals, thereby achieving the purpose of reducing the power consumption of the target vehicle and the physical car key.

[0150] In another possible implementation, the car key terminal includes only the user terminal, that is, only the user terminal is within the second communication connection range. In this case, see Figure 6 , Figure 6 The process of the vehicle key terminal positioning method provided in the illustrated embodiment may include:

[0151] S400: When the vehicle controller enters the sleep mode and the user terminal is within the second communication connection range, the vehicle-side digital key controller monitors a first wake-up event.

[0152] In a possible implementation, S400 may refer to Figure 3 The implementation of S100 in the illustrated embodiment will not be repeated here.

[0153] S401: If the duration of monitoring the first wake-up event reaches a second duration, the vehicle-side digital key controller stops locating the user terminal.

[0154] In the case where the car key terminal only includes the user terminal, it is determined whether to stop locating the user terminal based on the monitoring result of the first wake-up event. Specifically, if the duration of monitoring the first wake-up event reaches the second duration, the user terminal is stopped from being located. On the contrary, if the first wake-up event is detected within the second duration, the user terminal is maintained from being located. As for other implementation details of this step, they can all be implemented with reference to the relevant contents of any of the aforementioned embodiments, and will not be repeated here.

[0155] In a possible implementation, the specific implementation of the vehicle-side digital key controller stopping the positioning of the user terminal can be referred to Figure 4 S205 is implemented in the illustrated embodiment and will not be repeated here.

[0156] S402: The vehicle-side digital key controller sends a first notification message to the user terminal.

[0157] In a possible implementation, S402 may refer to Figure 4 S206 is implemented in the illustrated embodiment and will not be repeated here.

[0158] S403: The user terminal operates in a preset low power consumption mode in response to the first notification information.

[0159] In a possible implementation, S403 may refer to Figure 4 The implementation of S207 in the illustrated embodiment will not be repeated here.

[0160] S404: The user terminal displays the second notification information.

[0161] In one possible implementation, the user terminal may also display a second notification message while operating in a preset low-power mode, and prompt the user through the second notification message that the contactless unlocking / locking function of the user terminal becomes invalid before a communication connection is established with the target vehicle again, that is, in the current control process, the target vehicle, that is, the vehicle-side digital key controller stops locating the user terminal, and the target vehicle no longer obtains the actual location of the user terminal. In this case, if the user brings the user terminal close to the target vehicle again, the target vehicle cannot be controlled to open the door. Only after the user terminal moves out of the second communication connection range and completely disconnects the communication connection with the target vehicle, the user terminal can re-establish a communication connection with the target vehicle when it enters the second communication connection range. In this case, all control functions of the user terminal on the target vehicle are valid.

[0162] As mentioned above, the target vehicle stops locating the user terminal. When the user terminal is still in the second communication connection range, the two still establish an effective communication connection relationship. Therefore, the user can still issue control commands through the user terminal to wake up the target vehicle without affecting the normal use of the target vehicle. Based on this, the user terminal can also send control commands to the target vehicle in response to the user's control operations.

[0163] To sum up, when the user terminal is within the second communication connection range corresponding to the user terminal configured by the vehicle-side digital key controller, the positioning of the user terminal is stopped according to the monitoring result of the first wake-up event. Accordingly, the user terminal operates in the preset low power consumption mode, thereby achieving the purpose of reducing the power consumption of the target vehicle and the user terminal.

[0164] Furthermore, while reducing the power consumption of the user terminal, the user terminal can still respond to the user's control operation and send a control instruction for waking up the vehicle controller to the target vehicle, thereby controlling the target vehicle without affecting the user's use of the target vehicle.

[0165] It should be noted that for Figure 5 and Figure 6 In the illustrated embodiment, after the target vehicle stops locating the car key terminal, the target vehicle can still respond to the aforementioned second wake-up event and exit the sleep mode. For the specific implementation of this process, reference can be made to the aforementioned content and will not be repeated here.
