Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to a method and device for controlling an unlocking mode of a vehicle in the field of vehicle technology, and a vehicle. Background Art

[0002] With the development of vehicle technology, more and more vehicles have digital key functions. When users configure mobile terminals such as mobile phones as digital keys, they can use mobile terminals to quickly unlock and start the vehicle. When designing digital keys, the working area of ​​the digital key is usually divided into an unlocking area and a starting area. When the digital key is in the unlocking area, the vehicle can be unlocked but cannot be started. Correspondingly, when the digital key is in the starting area, the vehicle can be started but cannot be unlocked.

[0003] In related technologies, vehicles usually support a key sharing authorization function, that is, by logging into a mobile phone application with the car owner's account to share the digital key with the mobile terminals of other family members and friends. In this way, the vehicle has at least two legal digital keys, and there may also be scenarios where more than two digital keys appear around the vehicle at the same time.

[0004] In this scenario, after the owner and his family get out of the car, the family may leave a digital key in the car. After the owner locks the car with the digital key and leaves the car, the car will automatically connect to the digital key left in the car. Then, when the car needs to be unlocked, since the car can only connect to one digital key and this digital key is located in the starting area of ​​the car, the car cannot be unlocked. If the owner does not carry the physical key, the car cannot be unlocked, resulting in a poor user experience. Summary of the invention

[0071] The following will be combined with the accompanying drawings to clearly and thoroughly describe the technical solutions in this application. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0072] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features reflected. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0073] In order to illustrate the technical solution provided by the embodiments of the present application, some terms involved in the embodiments of the present application are first introduced.

[0074] Digital key: A digital key is a vehicle access control system based on digital technology. It uses a smartphone to communicate with the vehicle through wireless technology to achieve functions such as remote unlocking of doors and starting the engine. The emergence of digital keys not only simplifies the way car owners interact with their vehicles, but also improves safety and convenience.

[0075] Bluetooth (Blue Tooth, BT): Bluetooth is a radio technology that supports short-range communication between devices (generally within 10m), and can exchange wireless information between many devices including mobile phones, PDAs, wireless headsets, laptops, and related peripherals.

[0076] Ultra Wide Band (UWB): It is a wireless carrier communication technology that does not use a sinusoidal carrier but instead uses nanosecond-level non-sinusoidal narrow pulses to transmit data, so it occupies a wide spectrum range.

[0077] In the related art, the vehicle has at least two unlocking modes of the digital key, one of which is the normal mode (the first unlocking mode in the present application), and the other is the convenient mode (the second unlocking mode in the present application). In the normal mode, the starting area inside the vehicle and the unlocking area outside the vehicle are clearly divided. When the digital key is in the starting area, the vehicle can be powered on and off and started but cannot be unlocked. When the digital key is in the unlocking area, the vehicle can be unlocked but cannot be powered on and off and started. Under normal circumstances, the vehicle is in normal mode. In the convenient mode, the starting area and the unlocking area are merged into an overall area. When the digital key is in the overall area, the vehicle can be powered on and off and started, and can also be unlocked.

[0078] Vehicles usually support a key sharing authorization function, which is to share the digital key with other family and friends' mobile terminals by logging into a mobile application with the car owner's account. In this way, the vehicle has at least two legal digital keys. There may also be scenarios where more than two digital keys appear around the vehicle at the same time. For the sake of ease of explanation, the owner's digital key is referred to as digital key A, and the digital key of the owner's family or friends is referred to as digital key B.

[0079] The vehicle is in normal mode, and the owner and his family go on a self-driving trip. Initially, digital key A is connected to the vehicle through Bluetooth, and can control the vehicle start and unlock functions. The Bluetooth signals of digital key A and digital key B are both turned on and are in the car. After driving to the destination, the owner and his family get off the car, but the family forgets digital key B in the car. The owner carries digital key A into the unlocking area, performs the car locking action and moves away from the vehicle to the outside of the Bluetooth connection area. At this time, the Bluetooth communication between digital key A and the vehicle is disconnected, but because there is a legal digital key B in the car and Bluetooth is turned on, the vehicle will connect to digital key B at this time. Later, when the owner returns to the vicinity of the vehicle with digital key A and tries to unlock the vehicle, he will find that the vehicle cannot be unlocked because the only Bluetooth channel of the vehicle is occupied by digital key B forgotten in the car, and digital key A cannot connect to the vehicle. The vehicle is in normal mode, and the vehicle start area where digital key B is located only allows the vehicle to start but not unlock the vehicle. At this time, the car owner can only unlock the car door with the physical key. Once he goes out without the physical key, he can only open the car door through a locksmith company or by violently breaking the window. The above problems will cause serious complaints from car owners and the user experience is poor.

[0080] After introducing some terms involved in the embodiments of the present application, the implementation environment of the embodiments of the present application is introduced below. Figure 1The implementation environment of the vehicle unlocking mode control method provided in the embodiment of the present application includes a vehicle terminal 101, a gateway 102 and a vehicle body controller 103.

[0081] The vehicle terminal 101 has data processing capabilities, and can obtain vehicle-related data and process the obtained data, thereby triggering control instructions or feeding back processing results. In the embodiment of the present application, the vehicle terminal 101 is integrated with a digital key controller, and the digital key controller can realize the related functions of the digital key.

[0082] The gateway 102 is connected to the vehicle terminal 101 and the vehicle body controller 103 via a bus. As a transfer station for data transmission, the gateway 102 can realize format conversion and packaging of data. In addition, the vehicle terminal 101 can establish a connection with the external network through the gateway 102 .

[0083] The body controller 103 is used to control the body of the vehicle. For example, in the embodiment of the present application, the body controller 103 can control the unlocking, powering on and off, and starting of the vehicle.

[0084] After introducing the implementation environment of the embodiment of the present application, the application scenario of the technical solution provided by the embodiment of the present application is introduced below. The technical solution provided by the embodiment of the present application can be applied in a scenario where a digital key function is configured and only supports connection with one digital key at the same time. When the vehicle is in normal mode (first unlocking mode), when the vehicle is locked by a digital key and there is another digital key in the vehicle, the unlocking mode of the vehicle is adjusted from normal mode to convenient mode (second unlocking mode), or the vehicle is controlled to add the digital key in the vehicle to the blacklist, so that the user can unlock the vehicle directly or unlock the vehicle with the digital key held, avoiding the situation where the vehicle cannot be unlocked, thereby improving the user experience.

[0085] After introducing the implementation environment and application scenarios of the embodiments of the present application, the technical solutions provided by the embodiments of the present application are introduced below. Figure 2 Taking the execution subject as a vehicle-mounted terminal as an example, the method includes the following steps.

[0086] 201. When the vehicle is in a first unlocking mode and locked by a first digital key, the vehicle terminal determines whether a second digital key exists in the vehicle.

[0087] Among them, in the first unlocking mode, when the digital key is outside the vehicle, the vehicle can be unlocked. When the digital key is inside the vehicle, the vehicle cannot be unlocked. The vehicle can establish a connection with one digital key at the same time, that is, the vehicle is a vehicle with a digital key function and only supports connection with one digital key at the same time. The first unlocking mode is a normal mode, that is, a mode that divides the start area and the unlocking area. When the digital key is in the unlocking area, the vehicle can be unlocked. When the digital key is in the start area, the vehicle cannot be unlocked. In the embodiment of the present application, the start area refers to the area inside the vehicle, and the unlocking area refers to the area outside the vehicle. The first digital key is the mobile terminal of the owner, such as the mobile phone of the owner. Completing the locking by the first digital key means that when the vehicle is controlled to be locked, the vehicle is connected to the first digital key and the first digital key is located in the unlocking area. The second digital key is another legal digital key of the vehicle, and the second digital key is a mobile terminal of the owner's family or friend. In some embodiments, the second digital key is a subsidiary digital key of the first digital key, that is, the second digital key is granted by the first digital key. Since the vehicle only supports connection with one digital key at a time, the connection between the vehicle and the first digital key has been disconnected before determining whether the second digital key exists in the vehicle.

[0088] 202. When the second digital key is present in the vehicle, the vehicle-mounted terminal adjusts the unlocking mode of the vehicle from the first unlocking mode to the second unlocking mode, or disconnects the second digital key and adds the second digital key to a blacklist.

[0089] Among them, in the case of the first unlocking mode, if there is a second digital key in the vehicle, the second digital key will be connected to the vehicle, so that the digital key will be recognized to be in the starting area, and the vehicle will not be able to be unlocked. Since the vehicle has been locked by the first digital key before, the vehicle can no longer be unlocked by the digital key at this time. If the user does not carry a mechanical key, there is no way to enter the vehicle. In the second unlocking mode, the vehicle can be unlocked when the digital key is inside or outside the vehicle. The unlocking mode is adjusted from the first unlocking mode to the second unlocking mode, so that the starting area and the unlocking area are integrated into an integral area. Then, when the vehicle is connected to the second digital key, the vehicle can also be unlocked by the unlocking button of the vehicle. Alternatively, the connection with the second digital key is disconnected and the second digital key is added to the blacklist, so that the vehicle can be connected with other digital keys. When the user returns to the vicinity of the vehicle with the first digital key, the first digital key can be used to unlock the vehicle.

[0090] Through the technical solution provided by the embodiment of the present application, when the vehicle is in the first unlocking mode and the first digital key is used to complete the locking, it is determined whether there is a second digital key in the vehicle. When the second digital key is in the vehicle, the unlocking mode is adjusted from the first unlocking mode to the second unlocking mode, or the connection with the second digital key is disconnected and the second digital key is added to the blacklist, so that the vehicle can be unlocked even when there is another digital key in the vehicle, which greatly improves the user experience.

[0091] It should be noted that the above steps 201-202 are a simple description of the control method of the unlocking mode of the vehicle provided in the embodiment of the present application. The control method of the unlocking mode of the vehicle provided in the embodiment of the present application will be described in more detail below with reference to some examples. Figure 3 Taking the execution subject as a vehicle-mounted terminal as an example, the method includes the following steps.

[0092] 301. When the vehicle is in a first unlocking mode and is locked by a first digital key, the vehicle terminal determines whether a second digital key exists in the vehicle.

[0093] Among them, in the first unlocking mode, when the digital key is outside the vehicle, the vehicle can be unlocked. When the digital key is inside the vehicle, the vehicle cannot be unlocked. The vehicle can establish a connection with one digital key at the same time, that is, the vehicle is a vehicle with a digital key function and only supports connection with one digital key at the same time. The first unlocking mode is a normal mode, that is, a mode that divides the start area and the unlocking area, and when the digital key is in the unlocking area, the vehicle can be unlocked. When the digital key is in the start area, the vehicle cannot be unlocked. In an embodiment of the present application, the start area refers to the area inside the vehicle, and the unlocking area refers to the area outside the vehicle. The first digital key is the owner's mobile terminal, such as the owner's mobile phone. The locking is completed by the first digital key, which means that when the vehicle is controlled to be locked, the vehicle is connected to the first digital key and the first digital key is located in the unlocking area. In addition, the locking is completed by the first digital key, which means that when the vehicle is connected to the first digital key and the first digital key is located in the unlocking area, the locking command is sent to the vehicle by the first digital key, and the vehicle is locked, or the unlocking button of the vehicle is pressed to trigger the locking command, and the vehicle is locked. The second digital key is another legal digital key of the vehicle, and the second digital key is a mobile terminal of the owner's family or friends. In some embodiments, the second digital key is an auxiliary digital key of the first digital key, that is, the second digital key is granted by the first digital key. Since the vehicle only supports connection with one digital key at the same time, the connection between the vehicle and the first digital key has been disconnected before determining whether the second digital key exists in the vehicle.

[0094] In a possible implementation, when the vehicle is in the first unlocking mode and the first digital key is used to complete the locking, the vehicle terminal searches for the digital key in the vehicle through a broadcast signal. If the digital key is found, the vehicle terminal determines that the second digital key is in the vehicle. If the digital key is not found, the vehicle terminal determines that the second digital key does not exist in the vehicle.

[0095] The type of broadcast signal is associated with the connection method between the digital key and the vehicle. When the digital key is connected to the vehicle via Bluetooth (BT), the broadcast signal is a signal for searching for Bluetooth devices; when the digital key is connected to the vehicle via Ultra Wideband (UWB), the broadcast signal is a signal for searching for Ultra Wideband devices. Searching for digital keys in the vehicle through broadcast signals means adjusting the signal strength of the broadcast signal so that the coverage of the advertising signal is as close to the vehicle as possible. When there is a second digital key in the vehicle, the vehicle terminal will establish a connection with the second digital key.

[0096] In this implementation, a digital key search is performed in the vehicle through a broadcast signal to determine whether the second digital key exists in the vehicle, and the efficiency of determining the second digital key is relatively high.

[0097] The following two examples illustrate the method of searching for a digital key in a vehicle through a broadcast signal in the above embodiment.

[0098] Example 1: When the vehicle is in the first unlocking mode and is locked by the first digital key, the vehicle terminal actively disconnects the connection with the first digital key after a first preset time and searches for the digital key with a broadcast signal of a first signal strength, where the first signal strength is the signal strength for searching for the digital key in the vehicle.

[0099] The first preset duration is set by a technician according to actual conditions, such as 5 seconds, etc., and the embodiment of the present application does not limit this. The first signal strength is less than the second signal strength during a normal Bluetooth key search, so that the broadcast signal is limited to the vehicle. The first signal strength is calibrated and set by a technician according to actual conditions, and the embodiment of the present application does not limit this.

[0100] For example, when the vehicle is in the first unlocking mode and connected to the first digital key, in response to receiving a locking success instruction sent by the body controller, the vehicle terminal determines that locking is completed by the first digital key. The locking success instruction is sent by the body controller after completing the locking operation and is used to indicate that locking is completed. When it is determined that locking is completed by the first digital key, the vehicle terminal starts timing. When the timing reaches the first preset time, the vehicle terminal performs a disconnection action to actively disconnect the connection with the first digital key. The vehicle terminal sends a broadcast signal with a first signal strength to search for digital keys.

[0101] Example 2: When the vehicle is in the first unlocking mode and is locked by the first digital key, the vehicle terminal waits for the connection with the first digital key to be disconnected and then searches for the digital key with the broadcast signal of the first signal strength.

[0102] Among them, the disconnection with the first digital key means that the first digital key is away from the vehicle.

[0103] For example, when the vehicle is in the first unlocking mode and connected to the first digital key, in response to receiving a locking success instruction sent by the vehicle body controller, the vehicle terminal determines that locking is completed by the first digital key. The vehicle terminal determines the connection status between the vehicle and the first digital key, and when the connection with the first digital key is disconnected, the vehicle terminal sends a broadcast signal with a first signal strength to search for the digital key.

[0104] Another implementation of the above step 301 is described below.

[0105] In a possible implementation, when the vehicle is in the first unlocking mode and the first digital key is used to complete the locking, the vehicle terminal searches for the digital key through a broadcast signal. When the searched digital key is located in the vehicle, the vehicle terminal determines that the second digital key is in the vehicle. When the searched digital key is located outside the vehicle, or the digital key is not found, the vehicle terminal determines that the second digital key does not exist in the vehicle.

[0106] Among them, searching for digital keys through broadcast signals refers to sending broadcast signals with normal signal strength, so that the technical solution provided in the embodiments of the present application can also be implemented when the signal strength of the broadcast signal cannot be adjusted.

[0107] In this implementation, a digital key search is performed through a broadcast signal, and whether a second digital key exists in the vehicle is determined based on the search results. The efficiency of determining the second digital key is relatively high.

[0108] In addition, based on the above-mentioned embodiment, the following steps can also be performed.

[0109] In some embodiments, when the digital key is searched and the number of the digital keys searched is 1, the vehicle terminal determines whether the digital key is the first digital key. When the digital key is the first digital key, the vehicle terminal determines that there is no second digital key in the vehicle. When the digital key is not the first digital key, the vehicle terminal determines that there is a second digital key in the vehicle. When the digital key is searched and the number of the digital keys searched is greater than 1, the vehicle terminal determines whether the searched digital key is inside or outside the vehicle. When there is a digital key located in the vehicle, the vehicle terminal determines that there is a second digital key in the vehicle. When there is no digital key located in the vehicle, the vehicle terminal determines that there is no second digital key in the vehicle.

[0110] The following two examples illustrate the manner of searching for a digital key through a broadcast signal in the above embodiment.

[0111] Example 1: When the vehicle is in the first unlocking mode and is locked by the first digital key, the vehicle terminal actively disconnects the connection with the first digital key after a first preset time and searches for the digital key with a broadcast signal of a second signal strength, where the second signal strength is the signal strength for searching for the digital key in the vehicle.

[0112] Among them, the second signal strength is the signal strength during normal Bluetooth key search, so that Bluetooth key search can be performed inside and outside the vehicle. The second signal strength is calibrated and set by technicians according to actual conditions, and the embodiment of the present application does not limit this.

[0113] For example, when the vehicle is in the first unlocking mode and connected to the first digital key, in response to receiving a locking success instruction sent by the body controller, the vehicle terminal determines that the locking is completed by the first digital key. The locking success instruction is sent by the body controller after the locking operation is completed, and is used to indicate that the locking is completed. When it is determined that the locking is completed by the first digital key, the vehicle terminal starts timing. When the timing reaches the first preset time, the vehicle terminal performs a disconnection action to actively disconnect the connection with the first digital key. The vehicle terminal sends a broadcast signal with a second signal strength to search for digital keys.

[0114] Example 2: When the vehicle is in the first unlocking mode and is locked by the first digital key, the vehicle terminal waits for the connection with the first digital key to be disconnected and then searches for the digital key with the broadcast signal of the second signal strength.

[0115] For example, when the vehicle is in the first unlocking mode and connected to the first digital key, in response to receiving a locking success instruction sent by the vehicle body controller, the vehicle terminal determines that locking is completed by the first digital key. The vehicle terminal determines the connection status between the vehicle and the first digital key, and when the connection with the first digital key is disconnected, the vehicle terminal sends a broadcast signal with a second signal strength to search for the digital key.

[0116] The following is a description of a method for determining whether the digital key is located inside or outside the vehicle in the above embodiment.

[0117] In a possible implementation, when the digital key is searched, the vehicle terminal determines the connection signal strength connected to the digital key. When the connection signal strength is greater than or equal to the connection signal strength threshold, the vehicle terminal determines that the digital key is located outside the vehicle; when the connection signal strength is less than the connection signal strength threshold, the vehicle terminal determines that the digital key is located inside the vehicle.

[0118] Among them, the connection signal strength threshold is calibrated and configured by technical personnel according to actual conditions, and the embodiments of the present application do not limit this.

[0119] 302. When the second digital key is stored in the vehicle, the vehicle-mounted terminal adjusts the unlocking mode of the vehicle from the first unlocking mode to the second unlocking mode.

[0120] Among them, in the case of the first unlocking mode, if there is a second digital key in the vehicle, the second digital key will be connected to the vehicle, so that it will be recognized that the digital key is in the starting area, and the vehicle will not be able to be unlocked. Since the vehicle has been locked by the first digital key before, the vehicle can no longer be unlocked by the digital key at this time. If the user does not carry a mechanical key, there is no way to enter the vehicle. In the second unlocking mode, the vehicle can be unlocked when the digital key is inside or outside the vehicle, and the unlocking mode is adjusted from the first unlocking mode to the second unlocking mode, so that the starting area and the unlocking area are integrated into an integral area. Then, when the vehicle is connected to the second digital key, the vehicle can also be unlocked by the vehicle's unlocking button.

[0121] In some embodiments, when there is a second digital key in the vehicle, in addition to adjusting the unlocking mode in step 302 , at least one of the following steps can also be performed.

[0122] In a possible implementation, the vehicle-mounted terminal controls the vehicle to honk the horn and flash the lights in a preset manner.

[0123] The preset mode is set by the technician according to the actual situation, such as double flash mode, etc., and the embodiments of the present application do not limit this. The purpose of controlling the vehicle to honk and flash the lights in a preset manner is to remind the driver and passengers that the second digital key is left in the vehicle. When the driver and passengers notice the honking and flashing lights, they can return to the vehicle to retrieve the second digital key.

[0124] In this embodiment, when there is a second digital key in the vehicle, the horn and lights are used to remind the user that the second digital key is left in the vehicle, so the user can be reminded in time when the user has not left the vehicle.

[0125] For example, the vehicle terminal sends a target control instruction to the vehicle body controller, and the target control instruction is used to instruct the vehicle to honk and flash lights in a preset manner. After receiving the target control instruction, the vehicle body controller controls the vehicle to honk and flash lights in a preset manner.

[0126] In a possible implementation, the vehicle-mounted terminal sends a prompt message to the first digital key, where the prompt message is used to prompt that the second digital key is left in the vehicle.

[0127] Among them, the first digital key is a mobile terminal, and sending a prompt message to the first digital key can promptly remind the user that the second digital key is left in the vehicle. The content and form of the prompt message are set by technical personnel according to actual conditions, and the embodiment of the present application does not limit this.

[0128] For example, the vehicle terminal sends the prompt information to the gateway, so that the gateway forwards the prompt information to the first digital key.

[0129] 303. In response to the unlocking button of the vehicle being pressed, the vehicle-mounted terminal unlocks the vehicle.

[0130] Among them, the unlock button is usually set on the door handle of the vehicle, or on the B-pillar and C-pillar of the vehicle, which is not limited in the embodiment of the present application.

[0131] In a possible implementation, in response to the unlocking button of the vehicle being pressed, the vehicle-mounted terminal sends an unlocking instruction to the vehicle body controller, so that the vehicle body controller unlocks the vehicle based on the unlocking instruction.

[0132] Under this implementation, since the vehicle's unlocking mode is switched to the second unlocking mode, when the vehicle is connected to the second digital key and the second digital key is located inside the vehicle (starting area), the vehicle can still be unlocked by pressing the unlock button. This enables the vehicle to be unlocked even when there is another digital key in the vehicle, greatly improving the user experience.

[0133] Through the technical solution provided by the embodiment of the present application, when the vehicle is in the first unlocking mode and the first digital key is used to complete the locking, it is determined whether there is a second digital key in the vehicle. When the second digital key is in the vehicle, the unlocking mode is adjusted from the first unlocking mode to the second unlocking mode, so that the vehicle can be unlocked even when there is another digital key in the vehicle, which greatly improves the user experience.

[0134] Another implementation method of the vehicle unlocking mode control method provided in the embodiment of the present application is described below. Figure 4 Taking the execution subject as a vehicle-mounted terminal as an example, the method includes the following steps.

[0135] 401. When the vehicle is in a first unlocking mode and is locked by a first digital key, the vehicle terminal determines whether a second digital key exists in the vehicle.

[0136] Among them, step 401 and step 301 belong to the same inventive concept, and the implementation process refers to the relevant description in the above step 301, which will not be repeated here.

[0137] 402. When the second digital key is stored in the vehicle, the vehicle-mounted terminal adjusts the unlocking mode of the vehicle from the first unlocking mode to the second unlocking mode.

[0138] Among them, step 402 and step 302 belong to the same inventive concept, and the implementation process refers to the relevant description in the above step 302, which will not be repeated here.

[0139] 403. After a second preset time period, the vehicle terminal disconnects the second digital key and adds the second digital key to a blacklist.

[0140] Among them, disconnecting the connection with the second digital key can free up the only connection channel between the vehicle and the digital key, so that the vehicle can establish a connection with other digital keys. Adding the second digital key to the blacklist means configuring the second digital key to be in an unconnectable state, thereby preventing the second digital key from establishing a connection with the vehicle again after the connection is disconnected. In the second unlocking mode, while the vehicle and the second digital key remain connected, the vehicle can be unlocked by pressing the unlocking button on the vehicle. After disconnecting the second digital key, people who do not carry other digital keys or physical keys cannot unlock the vehicle, thereby ensuring the safety of the vehicle. The second preset time length is set by the technician according to the actual situation, such as being set to 1 hour, etc., and the embodiments of the present application do not limit this.

[0141] In a possible implementation, after a second preset time period, the vehicle-mounted terminal disconnects the second digital key and adds the key identifier of the second digital key to a blacklist to prohibit the second digital key from establishing a connection with the vehicle again.

[0142] It should be noted that the blacklisting of the second digital key is temporary, and the permission to establish a connection between the second digital key and the vehicle can be restored when certain conditions are met.

[0143] In addition to the above step 403, after step 402, the following steps can also be performed.

[0144] In a possible implementation, the vehicle terminal determines whether there is a preset type of driver or passenger in the vehicle, where the preset type of driver or passenger is a driver or passenger older than an age threshold. If there is no preset type of driver or passenger in the vehicle, the vehicle terminal disconnects the second digital key and adds the second digital key to the blacklist.

[0145] The determination of whether there is a preset type of driver or passenger is to identify whether there is a child in the vehicle. The age threshold is set by a technician according to actual conditions, and the embodiment of the present application does not limit this.

[0146] Under this implementation mode, when the unlocking mode is adjusted to the second unlocking mode, it is determined whether there are drivers or passengers of a preset type in the vehicle. If there are no drivers or passengers of the preset type, the connection with the second digital key is disconnected and the second digital key is added to the blacklist to ensure the safety of the vehicle.

[0147] For example, the vehicle terminal obtains an image of the interior of the vehicle. The vehicle terminal performs target detection on the image of the interior of the vehicle to determine whether there is a driver or passenger in the image of the interior of the vehicle. If there is a driver or passenger in the image of the interior of the vehicle, the vehicle terminal determines the age of the driver or passenger. If the age of the driver or passenger is greater than the age threshold, or if there is no driver or passenger in the image of the interior of the vehicle, the vehicle terminal disconnects the second digital key and adds the second digital key to the blacklist.

[0148] For example, the vehicle terminal obtains the in-vehicle image through the in-vehicle image acquisition component. The vehicle terminal inputs the in-vehicle image into the target detection model, and performs target detection on the in-vehicle image through the target detection model to determine whether there are drivers and passengers in the in-vehicle image. In the case that there are drivers and passengers in the in-vehicle image, the vehicle terminal determines the age of the driver and passenger through the age recognition model. In the case that the age of the driver and passenger is greater than the age threshold, or there is no driver and passenger in the in-vehicle image, the vehicle terminal disconnects the second digital key and adds the second digital key to the blacklist.

[0149] The target detection model is a detection model for detecting people, and the age recognition model is a multi-classification model for classifying the detected drivers and passengers into corresponding ages. Both the target detection model and the age recognition model can adopt models in related technologies, which are not limited in the embodiments of the present application.

[0150] Based on the above implementation, optionally, when there are preset types of drivers and passengers in the vehicle, the vehicle-mounted terminal maintains a connection with the second digital key.

[0151] In the case where there is a preset type of occupant in the vehicle, the connection with the second digital key is maintained, so that the vehicle can be unlocked by pressing the unlock button, ensuring that the preset type of occupant is in a state where it can be rescued. For example, if the preset type of occupant is an infant, maintaining the connection between the vehicle and the second digital key enables the infant to receive timely assistance when he or she needs help (for example, when the vehicle is placed outdoors in hot weather, causing the temperature in the vehicle to rise rapidly).

[0152] 404. The vehicle terminal searches for a digital key outside the vehicle via a broadcast signal.

[0153] Among them, searching for a digital key outside the vehicle through a broadcast signal refers to adjusting the signal strength of the broadcast signal so that the coverage of the advertising signal is as large as possible.

[0154] In a possible implementation, the vehicle-mounted terminal performs a digital key search with a broadcast signal of a second signal strength, where the second signal strength is a signal strength for performing a digital key search outside the vehicle.

[0155] 405. In response to re-establishing the connection with the first digital key and completing the unlocking by the first digital key, the vehicle terminal removes the second digital key from the blacklist.

[0156] Among them, re-establishing the connection with the first digital key and completing the unlocking through the first digital key means that the driver and passenger carrying the first digital key have completed the unlocking of the vehicle and can take items from the vehicle or drive the vehicle as needed. Removing the second digital key from the blacklist is to restore the permission for the second digital key to establish a connection with the vehicle.

[0157] Through the technical solution provided by the embodiment of the present application, when the vehicle is in the first unlocking mode and the first digital key is used to complete the locking, it is determined whether there is a second digital key in the vehicle. When the second digital key is in the vehicle, the unlocking mode is adjusted from the first unlocking mode to the second unlocking mode, and the connection with the second digital key is disconnected after the second preset time and the second digital key is added to the blacklist, so that the vehicle can be unlocked even when there is another digital key in the vehicle, which greatly improves the user experience.

[0158] Another implementation method of the vehicle unlocking mode control method provided in the embodiment of the present application is described below. Figure 5 Taking the execution subject as a vehicle-mounted terminal as an example, the method includes the following steps.

[0159] 501. When the vehicle is in a first unlocking mode and is locked by a first digital key, the vehicle terminal determines whether a second digital key exists in the vehicle.

[0160] Among them, step 501 and step 301 belong to the same inventive concept, and the implementation process refers to the relevant description in the above step 301, which will not be repeated here.

[0161] 502. When the second digital key is stored in the vehicle, the vehicle-mounted terminal adjusts the unlocking mode of the vehicle from the first unlocking mode to the second unlocking mode.

[0162] Among them, step 502 and step 302 belong to the same inventive concept, and the implementation process refers to the relevant description in the above step 302, which will not be repeated here.

[0163] 503. In response to the unlocking button of the vehicle being pressed, the vehicle-mounted terminal actively disconnects from the second digital key and searches for the digital key outside the vehicle through a broadcast signal.

[0164] In a possible implementation, in response to the unlocking button of the vehicle being pressed, the vehicle-mounted terminal disconnects from the second digital key and searches for the digital key using a broadcast signal with a second signal strength.

[0165] Optionally, after step 503, the vehicle terminal executes the following step 504 or 505 according to actual conditions.

[0166] 504. When the first digital key is found, the vehicle-mounted terminal unlocks the vehicle.

[0167] Among them, when the first digital key is searched, it means that the driver and passenger of the vehicle have returned to the vehicle. At this time, the vehicle can be unlocked, which is more secure.

[0168] In a possible implementation, when the first digital key is searched, the vehicle terminal attempts to establish a connection with the first digital key. When the connection with the first digital key is established, the vehicle terminal sends an unlocking instruction to the vehicle body controller, so that the vehicle body controller unlocks the vehicle based on the unlocking instruction.

[0169] Through the above steps 501-504, the first digital key can be used to verify the identity of the unlocking person before unlocking the vehicle, so as to improve the safety of the vehicle.

[0170] 505. When the first digital key is not found, the vehicle terminal determines whether to unlock the vehicle based on the object image of the target object pressing the unlock button and the historical in-vehicle image.

[0171] Among them, the historical in-vehicle image is the in-vehicle image collected during the last driving of the vehicle, that is, the in-vehicle image collected before the vehicle was last shut down / powered off. The historical in-vehicle image can reflect the situation of the driver and passengers riding in the vehicle during the last trip.

[0172] In a possible implementation, if the first digital key is not searched, the vehicle terminal obtains an object image of the target object that presses the unlock button. Based on the object image and the historical in-vehicle image, the vehicle terminal determines whether the target object is the target driver or passenger of the vehicle, and the target driver or passenger is the driver or passenger who was in the vehicle during the last driving process. If the target object is the target driver or passenger, the vehicle terminal unlocks the vehicle. If the target object is not the target driver or passenger, the vehicle terminal keeps the vehicle in a locked state.

[0173] In this implementation, if the first digital key is not found, the collected object image and the historical in-vehicle image are used to determine whether the target object is the target driver or passenger. If the target object is the target driver or passenger, the vehicle unlocking is safer, so the vehicle is unlocked directly. If the target object is not the target driver or passenger, the vehicle unlocking is less safe, so the vehicle remains locked.

[0174] For example, when the first digital key is not searched, the vehicle terminal obtains the object image of the target object through the vehicle exterior image acquisition component on one side of the unlock button. The vehicle terminal performs facial segmentation on the object image to obtain the facial area of ​​the target object. The vehicle terminal uses the facial area to match the historical in-vehicle image to determine whether there is an image area matching the facial area in the historical in-vehicle image. In the case where there is an image area matching the facial area in the historical in-vehicle image, the vehicle terminal determines that the target object is the target driver and passenger of the vehicle. In the case where there is no image area matching the facial area in the historical in-vehicle image, the vehicle terminal determines that the target object is not the target driver and passenger of the vehicle. In the case where the target object is the target driver and passenger, the vehicle terminal sends an unlock instruction to the vehicle body controller so that the vehicle body controller unlocks the vehicle based on the unlock instruction. In the case where the target object is not the target driver and passenger, the vehicle terminal keeps the vehicle in a locked state.

[0175] Among them, the process of matching the facial area in the historical in-vehicle image is equivalent to a template matching process. Of course, in addition to the above-mentioned template matching method, other image recognition and processing technologies can also be used to determine whether the target object in the object image is the target driver or passenger in the historical in-vehicle image. The embodiments of the present application are not limited to this.

[0176] Another implementation method of the vehicle unlocking mode control method provided in the embodiment of the present application is described below. Figure 6 Taking the execution subject as a vehicle-mounted terminal as an example, the method includes the following steps.

[0177] 601. When the vehicle is in a first unlocking mode and is locked by a first digital key, the vehicle terminal determines whether a second digital key exists in the vehicle.

[0178] Among them, step 601 and step 301 belong to the same inventive concept, and the implementation process refers to the relevant description in the above step 301, which will not be repeated here.

[0179] 602. When the second digital key is present in the vehicle, the vehicle-mounted terminal adjusts the unlocking mode of the vehicle from the first unlocking mode to the second unlocking mode.

[0180] Among them, step 602 and step 302 belong to the same inventive concept, and the implementation process refers to the relevant description in the above step 302, which will not be repeated here.

[0181] 603. When the second digital key is a subsidiary digital key of the first digital key, in response to the second digital key becoming invalid, the vehicle-mounted terminal disconnects from the second digital key and searches for the digital key via a broadcast signal, and the first digital key is able to configure the second digital key to be invalid.

[0182] The second digital key is a subsidiary digital key of the first digital key, which means that the second digital key is issued by the first digital key, and the first digital key has control over the second digital key. The failure of the second digital key means that the second digital key can no longer be used to control the unlocking and starting of the vehicle, and the second digital key can no longer establish a connection with the vehicle. Disconnecting the connection with the second digital key can free up the only connection channel between the vehicle and the digital key, so that the vehicle can establish a connection with other digital keys.

[0183] In a possible implementation, when the second digital key is a subsidiary digital key of the first digital key, in response to the token transmitted by the second digital key being invalid, the vehicle terminal determines that the second digital key is invalid. The vehicle terminal disconnects from the second digital key and performs a digital key search using a broadcast signal with a second signal strength.

[0184] In some embodiments, a target application for controlling the vehicle is running on the first digital key, and in response to a permission removal operation on the second digital key in the target application, the second digital key is configured to be invalid.

[0185] Through the technical solution provided by the embodiment of the present application, when the vehicle is in the first unlocking mode and the locking is completed by the first digital key, it is determined whether there is a second digital key in the vehicle. When the second digital key is in the vehicle, the unlocking mode is adjusted from the first unlocking mode to the second unlocking mode. When the second digital key fails, the connection with the second digital key is disconnected, so that the first digital key can establish a connection with the vehicle, so that the vehicle can be unlocked even when there is another digital key in the vehicle, which greatly improves the user experience.

[0186] Another implementation method of the vehicle unlocking mode control method provided in the embodiment of the present application is described below. Figure 7 Taking the execution subject as a vehicle-mounted terminal as an example, the method includes the following steps.

[0187] 701. When the vehicle is in a first unlocking mode and is locked by a first digital key, the vehicle terminal determines whether a second digital key exists in the vehicle.

[0188] Among them, step 701 and step 301 belong to the same inventive concept, and the implementation process refers to the relevant description in the above step 301, which will not be repeated here.

[0189] 702. When the second digital key is present in the vehicle, the vehicle-mounted terminal disconnects the second digital key and adds the second digital key to the blacklist.

[0190] Among them, the connection with the second digital key is disconnected and the second digital key is added to the blacklist, so that the vehicle can be connected to other digital keys. In this way, even in the first unlocking mode, when the user returns to the vicinity of the vehicle holding the first digital key, the vehicle can establish a connection with the first digital key, so that the first digital key can be used to unlock the vehicle.

[0191] 703. In response to re-establishing a connection with the first digital key and completing unlocking through the first digital key, the vehicle terminal removes the second digital key from the blacklist.

[0192] Through the technical solution provided by the embodiment of the present application, when the vehicle is in the first unlocking mode and the first digital key is used to complete the locking, it is determined whether there is a second digital key in the vehicle. If there is a second digital key in the vehicle, the connection with the second digital key is disconnected and the second digital key is added to the blacklist, so that the vehicle can be unlocked even if there is another digital key in the vehicle, which greatly improves the user experience.

[0193] Figure 8is a schematic diagram of the structure of a control device for a vehicle unlocking mode provided in an embodiment of the present application, see Figure 8 The device includes: a digital key determination module 801 and a control module 802.

[0194] The digital key determination module 801 is used to determine whether there is a second digital key in the vehicle when the vehicle is in the first unlocking mode and is locked by the first digital key. In the first unlocking mode, when the digital key is outside the vehicle, the vehicle can be unlocked. When the digital key is inside the vehicle, the vehicle cannot be unlocked. The vehicle can establish a connection with one digital key at the same time.

[0195] The control module 802 is used to adjust the unlocking mode of the vehicle from the first unlocking mode to the second unlocking mode when a second digital key is present in the vehicle, or to disconnect the connection with the second digital key and add the second digital key to a blacklist. In the second unlocking mode, the vehicle can be unlocked whether the digital key is inside or outside the vehicle.

[0196] In a possible implementation, the digital key determination module 801 is used to search for a digital key in the vehicle through a broadcast signal when the vehicle is in a first unlocking mode and locking is completed by a first digital key. When the digital key is searched, it is determined that a second digital key is present in the vehicle. When the digital key is not searched, it is determined that the second digital key does not exist in the vehicle. Alternatively, when the vehicle is in a first unlocking mode and locking is completed by a first digital key, a digital key search is performed through a broadcast signal. When the searched digital key is located in the vehicle, it is determined that the second digital key is present in the vehicle. When the searched digital key is located outside the vehicle, or when the digital key is not searched, it is determined that the second digital key does not exist in the vehicle.

[0197] In a possible implementation, the digital key determination module 801 is used to actively disconnect the connection with the first digital key after a first preset time and perform a digital key search with a broadcast signal of a first signal strength when the vehicle is in the first unlocking mode and the vehicle is locked by the first digital key. The first signal strength is the signal strength for searching the digital key in the vehicle. Alternatively, when the vehicle is in the first unlocking mode and the vehicle is locked by the first digital key, wait for the connection with the first digital key to be disconnected before performing a digital key search with a broadcast signal of the first signal strength.

[0198] In a possible implementation manner, the control module 802 is further configured to disconnect the second digital key and add the second digital key to a blacklist after a second preset time period. The digital key search is performed outside the vehicle through a broadcast signal.

[0199] In a possible implementation, the control module 802 is further configured to remove the second digital key from the blacklist in response to re-establishing a connection with the first digital key and completing unlocking through the first digital key.

[0200] In a possible implementation, the device further includes:

[0201] The personnel recognition model is used to determine whether there is a preset type of driver or passenger in the vehicle, and the preset type of driver or passenger is a driver or passenger whose age is greater than an age threshold.

[0202] The control module 802 is also used to disconnect the second digital key and add the second digital key to a blacklist when there is no driver or passenger of a preset type in the vehicle.

[0203] In a possible implementation, the control module 802 is further configured to maintain the connection with the second digital key when there is a preset type of driver or passenger in the vehicle.

[0204] In a possible implementation manner, when there is a second digital key in the vehicle, the control module 802 is further configured to perform at least one of the following:

[0205] The vehicle is controlled to honk its horn and flash its lights in a preset manner.

[0206] A prompt message is sent to the first digital key, where the prompt message is used to prompt that the second digital key is left in the vehicle.

[0207] In a possible implementation, the control module 802 is further configured to, in response to the unlock button of the vehicle being pressed, unlock the vehicle. Alternatively, in response to the unlock button of the vehicle being pressed, actively disconnect the second digital key and perform a digital key search outside the vehicle via a broadcast signal. In the event that the first digital key is found, the vehicle is unlocked.

[0208] In a possible implementation, the device further includes:

[0209] The image acquisition module is used to acquire the object image of the target object pressing the unlock button when the first digital key is not found.

[0210] The object determination module is used to determine whether the target object is the target driver or passenger of the vehicle based on the object image and the historical in-vehicle image, wherein the historical in-vehicle image is the in-vehicle image captured during the last driving of the vehicle, and the target driver or passenger is the driver or passenger in the vehicle during the last driving.

[0211] The control module 802 is also used to unlock the vehicle when the target object is the target driver or passenger, and to keep the vehicle in a locked state when the target object is not the target driver or passenger.

[0212] In a possible implementation, the control module 802 is also used to, in a case where the second digital key is a subsidiary digital key of the first digital key, disconnect the second digital key and perform a digital key search via a broadcast signal in response to the second digital key becoming invalid, so that the first digital key can configure the second digital key to be invalid.

[0213] It should be noted that: the control device for the unlocking mode of the vehicle provided in the above embodiment only uses the division of the above functional modules as an example when controlling the unlocking mode of the vehicle. In actual application, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the vehicle is divided into different functional modules to complete all or part of the functions described above. In addition, the control device for the unlocking mode of the vehicle provided in the above embodiment and the control method embodiment of the unlocking mode of the vehicle belong to the same concept. The specific implementation process is detailed in the method embodiment and will not be repeated here.

[0214] Through the technical solution provided by the embodiment of the present application, when the vehicle is in the first unlocking mode and the first digital key is used to complete the locking, it is determined whether there is a second digital key in the vehicle. When the second digital key is in the vehicle, the unlocking mode is adjusted from the first unlocking mode to the second unlocking mode, or the connection with the second digital key is disconnected and the second digital key is added to the blacklist, so that the vehicle can be unlocked even when there is another digital key in the vehicle, which greatly improves the user experience.
