Description

Technical Field

[0001] This application relates to the automotive field, and more particularly to a vehicle lock control method, system, computer storage medium, and automobile. Background Technology

[0002] In the automotive industry, whether it's a traditional gasoline car or a new energy vehicle, the battery is a core component for vehicle operation and functionality, playing an irreplaceable and crucial role in the overall performance and daily use of the vehicle. For example, the low-voltage power supply for most gasoline or new energy vehicles is provided by low-voltage batteries, maintaining the normal operation of some vehicle functions during parking or driving, such as door opening and closing, trunk opening, and instrument panel power supply. Electric vehicles, especially new energy vehicles, also include high-voltage batteries, which not only power the vehicle but also replenish the low-voltage batteries when they are depleted. In some cases, when the low-voltage and / or high-voltage batteries are depleted, the vehicle experiences a power shortage. In other cases, when the vehicle battery is in extreme or abnormal conditions, such as a severe collision during driving causing the battery cables to disconnect, a power shortage can also occur. When a vehicle is powerless, due to insufficient power, normal vehicle operation cannot be guaranteed; for example, when a vehicle is powerless, it may not be able to unlock itself using electronic starting.

[0003] Existing technology proposes an emergency jump-start unlocking solution. Addressing situations where a vehicle is out of power or its battery is malfunctioning and there is no mechanical key available, this solution sets the vehicle to a state where it can receive external emergency power. Upon detecting an external emergency power signal, the vehicle can be unlocked using an electronic key. However, this technical solution emphasizes the macroscopic functional framework of the emergency unlocking function, without addressing the implementation issues or providing further details about the technical solution. Summary of the Invention

[0004] In view of this, embodiments of this application aim to provide a vehicle lock control method, system, computer storage medium, and automobile.

[0005] In a first aspect, a vehicle lock control method is provided, wherein the vehicle includes a lock control system, the method comprising: determining whether the vehicle is in an emergency power supply mode; receiving a vehicle control command sent by an electronic car key, wherein the vehicle control command includes an unlock command and a lock command, the unlock command and the lock command being sent by the electronic car key using the same button; when the vehicle is in an emergency power supply mode, the lock control system recognizes the vehicle control command as an unlock command and unlocks the vehicle.

[0006] According to the first aspect, when the vehicle is in emergency power supply mode, the lock control system recognizes the vehicle control command as an unlock command and unlocks the vehicle, including: when the vehicle is in emergency power supply mode, the lock control system recognizes the vehicle control command as an unlock command and unlocks the left front door lock of the vehicle.

[0007] According to the first aspect, or any implementation of the first aspect above, before receiving the vehicle control command sent by the car electronic key, the process includes: performing legal authentication on the car electronic key; if the legal authentication of the car electronic key is successful, establishing a connection with the car electronic key and receiving the vehicle control command sent by the car electronic key; or if the legal authentication of the car electronic key fails, failing to establish a connection with the car electronic key.

[0008] According to the first aspect, or any implementation of the first aspect above, the electronic car key is legally authenticated, including: when it is determined that the vehicle is in emergency power supply mode, actively searching for the electronic car key via Bluetooth, and legally authenticating the electronic car key after it is found.

[0009] Determining whether a vehicle is in emergency power supply mode according to the first aspect, or any implementation of the first aspect above, includes: determining whether a vehicle is in emergency power supply mode according to a first condition, wherein the first condition includes the vehicle's power supply voltage being lower than a first threshold, and when the power supply voltage is lower than the first threshold, the vehicle is powered by an emergency power supply, and the first threshold is a value greater than or equal to 12V.

[0010] According to the first aspect, or any implementation of the first aspect above, when the vehicle is in emergency power supply mode, the lock control system recognizes the vehicle control command as an unlocking command and unlocks the vehicle, including: when the vehicle is in emergency power supply mode, the lock control system recognizes the vehicle control command as an unlocking command and unlocks the door lock and releases the door handle power.

[0011] According to the first aspect, or any implementation of the first aspect above, when the vehicle is in emergency power supply mode, the lock control system recognizes the vehicle control command as an unlock command and unlocks the vehicle, including: when the vehicle is in emergency power supply mode, the lock control system only recognizes the locking command as an unlock command and unlocks the vehicle.

[0012] Secondly, this application provides a vehicle lock control system, which includes: a judgment module for judging whether the vehicle is in emergency power supply mode; a receiving module for receiving vehicle control commands sent by the car electronic key, wherein the vehicle control commands include unlock commands and lock commands, and the unlock commands and lock commands are sent by the car electronic key using the same button; and a control module for recognizing the vehicle control commands as unlock commands when the vehicle is in emergency power supply mode, and unlocking the vehicle.

[0013] Thirdly, this application provides an automobile that includes a vehicle lock control system provided in the second aspect.

[0014] Fourthly, this application provides a computer-readable storage medium for computer-executable program code, the program code including a vehicle lock control method for performing the first aspect and any of the possible implementations of the first aspect.

[0015] Fifthly, embodiments of this application provide a computer program that includes commands for executing the vehicle lock control method in the first aspect and any possible implementation thereof.

[0016] In the case of unlocking the car door in emergency power supply mode, if the unlocking and locking functions of the car electronic key are located on the same button, the command sent by that button can be recognized as an unlocking command to unlock the vehicle and unlock other functions of the vehicle. This avoids the problem that the car electronic key cannot send an unlocking command to unlock the vehicle in the case of unlocking the car door in emergency power supply mode.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0026] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0027] The terms "first" and "second," etc., used in the specification and claims of this application are used to distinguish different objects, not to describe a specific order of objects. For example, "first target object" and "second target object," etc., are used to distinguish different target objects, not to describe a specific order of target objects.

[0028] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0029] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0030] In the automotive industry, whether it's a traditional gasoline car or a new energy vehicle, the battery is a core component for vehicle operation and functionality, playing an irreplaceable and crucial role in the overall performance and daily use of the vehicle. For example, the low-voltage electricity used in the vast majority of gasoline cars or new energy vehicles is provided by low-voltage batteries (which provide power to the small electrical systems and auxiliary equipment of electric vehicles, and can be simply referred to as "small batteries"). Low-voltage batteries play a very important role in the normal operation of the vehicle. For instance, in gasoline cars, low-voltage batteries can be used to start the vehicle's engine, or, when the engine is not running, they can supply power to other modules that require electricity, such as door switches, trunk opening, and instrument panel power. Electric vehicles in the new energy vehicle sector can not only be driven by the vehicle's own high-voltage battery (which provides power to the electric motor, also known as "large battery" or "power battery"), but they can also break away from the strong dependence of traditional gasoline cars on small batteries by replenishing the low-voltage batteries in a timely manner to ensure that the low-voltage voltage can support the normal operation of the electric vehicle.

[0031] Whether it's a traditional gasoline car or a new energy vehicle that has made significant progress in recent years, unlocking a vehicle can be done using either a traditional mechanical key or an electronic key for electronic starting. This electronic unlocking process requires a low-voltage battery to provide power to the relevant systems. For example, a vehicle can include an electronic key start system, which can be connected to the electronic key to remotely unlock and start the vehicle. When unlocking a vehicle with a mechanical key, the mechanical key opens the vehicle through its mechanical structure; when unlocking with an electronic key, the electronic key start system can communicate with the electronic key and receive relevant operation commands, such as unlocking the doors or opening the trunk. Electronic keys can be wristband keys, Bluetooth keys, cloud service keys, near-field communication (NFC) card keys, etc., and can also be simply called electronic keys.

[0032] While a vehicle is parked, some devices remain in standby mode, continuing to consume power from the low-voltage battery. If the vehicle is parked for an extended period, the low-voltage battery, which powers the electronic key start system, will be completely depleted. If the vehicle is a gasoline car, the battery power is insufficient to start the engine, preventing the engine from recharging the low-voltage battery. If the vehicle is an electric car, the high-voltage battery's capacity is also limited, preventing it from recharging the low-voltage battery. Therefore, when the low-voltage battery is depleted, the vehicle is in a state of low charge, unable to function properly. For example, in a low-charged state, the low-voltage battery cannot provide the minimum power required for electronic starting, so the vehicle cannot be unlocked using the electronic key and must be unlocked using the mechanical key. However, with technological advancements, the automotive industry is trending towards replacing traditional mechanical keys with electronic keys and gradually phasing out the use of mechanical keys. However, when the vehicle is out of power, it cannot be opened without a mechanical key. The only way to open the vehicle is through forced operation, such as prying open the door lock. However, such operation will bring great risks and inconvenience to the user.

[0033] In the existing technology, an emergency jump-start unlocking solution has been proposed. Figure 1 The vehicle shown is in a state of low battery. Figure 1 The emergency jump-start unlocking scheme shown may include steps S110 to S130.

[0034] Step S110: When the vehicle is in a state of low battery, the vehicle can be set to a state that allows it to receive power from an external emergency power source.

[0035] Step S120: After the vehicle receives an external emergency power supply signal, it can communicate with the electronic key to receive the electronic key's control signal.

[0036] In step S130, when the vehicle receives the unlock signal from the electronic key, the door lock can be unlocked.

[0037] In some cases, when the vehicle battery malfunctions and cannot function properly, such as when the battery cable is disconnected due to a collision, the vehicle can be set to allow receiving external emergency power.

[0038] based on Figure 1The emergency jump-start unlocking solution shown is understood to be a way to enable a vehicle to receive external emergency power when it is out of power or the battery is malfunctioning, without a mechanical key. Upon detecting an external emergency power signal, the vehicle can be unlocked using the car's electronic key. However, this technical solution emphasizes the macroscopic functional framework of the emergency unlocking function, without addressing the implementation issues or providing further details.

[0039] For example, when unlocking a car door using emergency power mode, if the car's electronic key's locking and unlocking functions are located on the same button, it's impossible to send an unlock command via the electronic key to unlock other car functions. For instance, for aesthetic reasons, some gasoline cars and most electric vehicles use hidden door handles. If the vehicle's doors are already unlocked using emergency power mode, and you want to unlock the vehicle using the electronic key to simultaneously trigger the door handle's electric release, the electronic key might be unable to send the unlock command correctly, preventing the vehicle from unlocking and thus preventing the electric release to open the door handle. Having the electronic key's locking and unlocking functions on the same button can be understood as the electronic key using a single physical button for both locking and unlocking. This could be achieved by pressing the button once to send an unlock command, pressing it a second time to send a lock command, and so on, cycling through the same physical button. Alternatively, the electronic key could be a car key with a screen, where the locking and unlocking functions are controlled by different icons located in the same position. Taking a mobile phone as a car electronic key as an example, an app from the vehicle manufacturer can be installed on the phone to enable command control of the vehicle. To maintain a minimalist design, the app interface uses only one icon to switch between different icons (unlock and lock) to control the locking and unlocking functions.

[0040] like Figure 2 As shown, taking a mobile phone as an electronic key as an example, in the mobile phone app interface for controlling the vehicle, the icons for the car lock switch can be switched in the same position, such as... Figure 2 The car lock icon in the upper middle image is the locked icon. Figure 2 The car lock icon in the lower middle image is the unlock icon. (Combined with...) Figure 3The flowchart shows that when the car lock icon is displayed as a locked icon, clicking it sends an unlock command, and the icon then switches to an unlock icon. Conversely, when the icon is displayed as an unlock icon, clicking it sends a locked command, and the icon then switches back to a locked icon. When the vehicle is out of power and the doors are unlocked, if a mobile phone is connected to the vehicle, the phone screen will display an unlock icon because the vehicle is already unlocked. In this case, the user can only send a locked command to the vehicle by clicking this icon, and cannot send an unlock command normally. The user can only send a locked command to the vehicle before they can send an unlock command. In some cases, such as when the vehicle uses a hidden door handle, even if the vehicle is unlocked, the door handle may not be able to release electricity due to the vehicle's low power, requiring a second unlocking to open the door. However, in some cases, the external emergency power supply connected to the vehicle has limited power and cannot support multiple communications and control commands between the vehicle and the electronic key, thus preventing the vehicle from unlocking normally. Related technologies do not offer corresponding solutions for similar detailed issues.

[0041] Based on the above problems, this application proposes a vehicle lock control method, which is described below in conjunction with... Figure 4 This method will be explained.

[0042] Figure 4 This is a schematic flowchart of a vehicle lock control method provided in an embodiment of this application. Figure 4 The method shown can be performed by a gasoline-powered vehicle or a new energy vehicle, which may include an electric vehicle. The vehicle may include a lock control system.

[0043] Figure 4 This includes steps S410 to S430.

[0044] Step S410: Determine whether the vehicle is in emergency power supply mode.

[0045] In some embodiments, when the vehicle is powered by an emergency power source, the vehicle may be considered to be in emergency power supply mode.

[0046] In some embodiments, when the vehicle's battery power is normal, it can support normal vehicle operation. However, when the vehicle's battery power is depleted, or the vehicle battery cannot supply power normally, the vehicle can be considered to be in a state of low power, and in this case, an emergency power supply can be connected to power the vehicle.

[0047] In some embodiments, it can be determined whether the vehicle is in emergency power supply mode based on a first condition, or it can be understood that it can be determined whether the vehicle needs to be connected to an emergency power source based on a first condition.

[0048] In some embodiments, the first condition may include the vehicle's supply voltage being lower than a first threshold. Optionally, when the supply voltage is lower than the first threshold, the vehicle is powered by an emergency power supply, and the vehicle is in emergency power supply mode. Optionally, when the supply voltage is greater than or equal to the first threshold, the vehicle can use the vehicle battery normally, and the vehicle is in normal mode. In some embodiments, the first threshold may be a value greater than or equal to 12V. Optionally, the supply voltage may be a 12V low-voltage battery.

[0049] In some embodiments, the emergency power supply may be a power module built into the vehicle or a power module external to the vehicle.

[0050] Optionally, the emergency power supply can be the wireless power receiving module mentioned in the related technologies above. The vehicle in this application embodiment may include the wireless power receiving module, so that when the vehicle is out of power, the wireless power receiving module can be reverse charged by an external control device, thereby supporting the vehicle to receive commands from the car electronic key and unlock the vehicle normally in emergency power supply mode.

[0051] Alternatively, the emergency power supply can also be the external emergency power supply mentioned in the related technologies above. This external emergency power supply can be a low-voltage power source outside the vehicle, such as a jump starter, a low-voltage battery, or other power carriers.

[0052] Alternatively, the emergency power supply can also be a backup low-voltage power supply built into the vehicle; the specific form is not limited in this application embodiment.

[0053] Step S420: Receive vehicle control command sent by the car electronic key.

[0054] In some embodiments, the vehicle can receive vehicle control commands sent by the electronic car key. For example, the vehicle can establish a connection with the electronic car key and communicate with it, and can receive vehicle control commands sent by the electronic car key. Optionally, the vehicle control commands may include unlocking and locking commands, thereby enabling unlocking and locking commands to be controlled by the electronic car key.

[0055] In some embodiments, the car electronic key may include the aforementioned wristband key, Bluetooth key, cloud service key, NFC card key, or mobile phone, etc. Optionally, when the car electronic key includes a Bluetooth module, the car electronic key and the vehicle can connect via Bluetooth; optionally, when the car electronic key is an NFC card key, the car electronic key and the vehicle can connect via NFC; optionally, with the widespread use of mobile phones, the car electronic key can be a mobile phone, which can connect to the vehicle via Bluetooth or ultra-wideband (UWB) communication.

[0056] In some embodiments, the unlocking and locking functions of a car electronic key can be located on the same button. This means that the car electronic key can use the same button to send unlock and lock commands to the vehicle. For example, the car electronic key can be one mentioned above that uses the same physical button to send unlock and lock commands. The car electronic key can also be one mentioned above that has a screen, where the unlocking and locking functions can be controlled by different icons located in the same icon position. Examples include mobile phones, watches, and wristbands with screens.

[0057] In step S430, the vehicle's lock control system can recognize the vehicle control command as an unlock command and unlock the vehicle.

[0058] In some embodiments, the vehicle's lock control system can receive a vehicle control command. When the vehicle is in emergency power supply mode, the vehicle control system can identify the vehicle control command as an unlocking command and unlock the vehicle.

[0059] Understandably, when a vehicle enters emergency power mode, the vehicle's locking control system can recognize any vehicle control command sent by the electronic key as an unlocking command and unlock the vehicle accordingly. For example, when the electronic key's lock and unlock functions are located on the same button, when the vehicle enters emergency power mode, whether the electronic key sends an unlocking command or a locking command through that button, the vehicle's locking control system can recognize it as an unlocking command. This avoids the problem of the electronic key being unable to send unlocking commands properly when unlocking in emergency power mode, thus preventing the vehicle from being unable to unlock.

[0060] In some embodiments, the vehicle may include two doors or four doors, and some models also include power doors. When the emergency power supply has limited power, it may not be sufficient to unlock all the vehicle doors, resulting in unlocking failure. Therefore, to improve the success rate of unlocking the vehicle with limited power, in some embodiments, only the left front door lock can be unlocked. Optionally, only the left front door lock motor can be unlocked. Compared to unlocking all the vehicle doors, unlocking only the left front door lock significantly improves the success rate of unlocking the vehicle when the emergency power supply has limited power.

[0061] In some embodiments, only one door lock of the vehicle may be unlocked. For example, the front right door of the vehicle.

[0062] In some instances, the vehicle's lock control system may also execute steps S410 and S420, and this application embodiment does not impose specific limitations on this.

[0063] pass Figure 4The vehicle lock control method shown allows for unlocking of the vehicle in emergency power mode. If the unlocking and locking functions of the car's electronic key are located on the same button, the command sent by that button can be recognized as an unlocking command to unlock the vehicle and unlock other vehicle functions. This avoids the problem that the car's electronic key cannot send unlocking commands to unlock the car normally in emergency power mode, allowing users to solve the problem of unlocking the vehicle in emergency power mode more conveniently and seamlessly.

[0064] With the continuous development of communication technology, communication security is becoming increasingly important in the field of communication. Therefore, the communication security of the connection between car electronic keys and vehicles is also crucial for protecting vehicles from unauthorized access and ensuring data security.

[0065] In some embodiments, when a vehicle receives a vehicle control command sent by an electronic car key, the vehicle needs to authenticate the electronic car key before establishing a connection with it. This is to prevent security issues caused by any electronic car key being able to send control commands to the vehicle. Alternatively, it can be considered that the electronic car key can only send vehicle control commands to the vehicle if it is a legitimate key belonging to the vehicle.

[0066] Optionally, when a user wants to send vehicle control commands to the vehicle using the electronic car key, the electronic car key can first send a legitimate authentication request to the vehicle. For example, the request can contain a pre-agreed key. After receiving the request, the vehicle determines whether the electronic car key is legitimate based on the request information and sends a successful authentication message to the electronic car key, establishing a connection between the vehicle and the electronic car key, thereby enabling the vehicle to receive vehicle control commands sent by the electronic car key.

[0067] Optionally, the vehicle can proactively initiate a legal authentication request for the car electronic key. Based on this request, the car electronic key can send its own relevant information to the vehicle. The vehicle can then verify the legitimacy of the car electronic key based on this information and send a successful authentication message to the car electronic key, establishing a connection between the vehicle and the car electronic key. This allows the vehicle to receive vehicle control commands sent by the car electronic key. In some embodiments, the car electronic key may include a Bluetooth module. When the vehicle is in emergency power mode, it can proactively search for the car electronic key via Bluetooth and initiate a legal authentication request to the found car electronic key with a Bluetooth module, thereby determining whether the car electronic key is a legitimate car electronic key for the vehicle. This design allows the vehicle to proactively search for the car electronic key and complete the legal authentication process when entering emergency power mode, reducing user operation time and making it more convenient to send commands to the vehicle and unlock it. Optionally, when the emergency power supply is limited, the car electronic key can be legally authenticated immediately upon connecting to the emergency power supply, improving the success rate of unlocking the vehicle in emergency power mode.

[0068] Optionally, the car key and the vehicle can also perform two-way authentication. In some embodiments, when a user wants to send vehicle control commands to the vehicle using the car key, the car key can first send a legitimate authentication request to the vehicle. After receiving the request, the vehicle determines whether the car key is legitimate based on the request information and sends a successful authentication message to the car key. Upon receiving the successful authentication message from the vehicle, the car key can determine whether the vehicle is legitimate. Only when the car key determines that the vehicle is legitimate will a connection be established between the vehicle and the car key, enabling the vehicle to receive vehicle control commands sent by the car key. In some embodiments, when the vehicle is in emergency power mode, it can proactively initiate a legitimate authentication request to the car key. The car key can determine whether the vehicle is legitimate based on the authentication request. After determining that the vehicle is legitimate, the car key sends its own relevant information to the vehicle. The vehicle can confirm the legitimacy of the car key based on this relevant information. When the vehicle determines that the car key is legitimate, it can send a successful authentication message to the car key, establishing a connection between the vehicle and the car key, thereby enabling the vehicle to receive vehicle control commands sent by the car key.

[0069] In some embodiments, if the vehicle fails to establish a valid connection with the electronic car key, the vehicle cannot establish a connection with the electronic car key. In other words, the vehicle cannot receive vehicle control commands sent by the electronic car key, thereby ensuring the communication security of the vehicle.

[0070] Traditional gasoline cars mostly use mechanical door handles, which rely on physical operation to open and close the doors. However, a small number of gasoline cars and most electric cars currently use concealed door handles for aesthetic reasons. Existing concealed door handles can be opened in several ways. For example, they can be triggered by sensing a signal from the car's electronic key, causing the door handle to pop out. Alternatively, the vehicle can receive an unlocking command from the electronic key, also triggering the door handle's electro-discharge and popping it out.

[0071] In some embodiments, vehicles with concealed door handles may be unable to open the door handles electrically even when the vehicle is unlocked due to insufficient battery power. Optionally, upon receiving an unlock command, the vehicle can simultaneously unlock the door locks and electrically release the door handles, allowing the user to open the door while simultaneously unlocking the vehicle using an unlock command, thus enabling the door to be opened electrically.

[0072] Optionally, to ensure that the user can open the car door in time after sending a vehicle control command via the car's electronic key, the time for electrically releasing the door handle can be longer than 5 seconds.

[0073] In some embodiments, a portion of the car's electronic key may include other functional buttons besides the lock / unlock button, such as the trunk opening and vehicle location functions. However, when the battery power is limited in emergency power mode, to ensure that the user can successfully unlock the vehicle using the car's electronic key, the vehicle will only be recognized as having an unlock command when it receives a lock command, and thus the vehicle will be unlocked. This can also be understood as the vehicle only unlocking when it receives an unlock or lock command in emergency power mode. For example, if the vehicle receives a vehicle location command or a trunk opening command in emergency power mode, the vehicle control system may not respond and will not perform any related operations.

[0074] The following is based on Figure 5 Taking an example, the embodiments of this application will be described in detail.

[0075] Figure 5 This is a schematic flowchart of a vehicle lock control method provided in an embodiment of this application. Figure 5The method shown can be performed by a gasoline vehicle or a new energy vehicle, which may include electric vehicles. Figure 5 The emergency power supply can be a low-voltage power source outside the vehicle, a wireless power receiving module built into the vehicle, or an emergency power supply built into the vehicle. Figure 5 The car electronic key can be either the electronic key mentioned above, or a mobile phone with the corresponding key application software installed by the vehicle manufacturer. Figure 5 The vehicles mentioned may include vehicle lock control systems.

[0076] Figure 5 This includes steps S510 to S530.

[0077] Step S510: Determine whether the vehicle is currently out of power or whether the vehicle's battery is malfunctioning.

[0078] If the vehicle battery is functioning normally, the method ends; if the vehicle is low on power or the battery is malfunctioning, the vehicle can receive emergency power and enters emergency power supply mode.

[0079] In step S520, when the vehicle is in emergency power supply mode, before the vehicle connects to the car electronic key, the vehicle can perform legitimate authentication of the car electronic key. If the authentication fails, the method ends; if the authentication is successful, the vehicle can receive vehicle control commands sent by the car electronic key.

[0080] Step S530: When the vehicle's electronic key is in emergency power supply mode, if the electronic key sends a non-locking command to the vehicle, such as a command to open the trunk, the vehicle's lock control system will not respond after recognizing the command; if the electronic key sends an unlocking command to the vehicle, the vehicle's control system can recognize the unlocking command as an unlocking command upon receiving it, and unlock the left front door lock and electrically release the left front door handle, thus ending the method.

[0081] In some embodiments, when the mobile phone is used as a car electronic key, the mobile application interface can use a single icon location to switch between different icons to control the locking and unlocking functions, such as... Figure 2 As shown in the image above, you can unlock the vehicle using the electric locomotive lock icon. After unlocking, the mobile app will display the following... Figure 2As shown in the image below, the icon has switched to the unlocked state. When the user needs to continue unlocking the vehicle using the car's electronic key, they can continue to click the lock icon. Since the vehicle is now in a low-battery state, when the vehicle key recognition module receives the vehicle control command sent by the car's electronic key, it can recognize the command as an unlock command and send the unlock command to the vehicle's left front door module to unlock the vehicle.

[0082] Figure 6 This is a schematic flowchart illustrating another vehicle lock control method according to an embodiment of this application. Figure 6 The method shown can be performed by a gasoline vehicle or a new energy vehicle as described above, and the new energy vehicle can include an electric vehicle. Figure 6 In this system, when the vehicle's battery is low, a 12V emergency unlocking power supply is used as an emergency power source. Figure 6 The vehicle in the text may include a vehicle lock control system, which can be... Figure 6 The vehicle key recognition module is located in the center of the vehicle. The left front door module can be used to receive unlock commands from the vehicle key recognition module and unlock the door lock.

[0083] When the vehicle's battery is low, a 12V emergency unlocking power supply can be connected to power the vehicle key recognition module and the vehicle's left front door module.

[0084] Once the vehicle key recognition module establishes a connection with the mobile phone, it receives vehicle control commands sent by the mobile phone.

[0085] When the vehicle key recognition module determines that it is powered by an emergency power supply, it can recognize the vehicle control command sent by the mobile phone as an unlock command and send it to the vehicle's left front door module via the LIN line.

[0086] In response to the unlock command, the vehicle's left front door module unlocks the door lock, thereby unlocking the vehicle.

[0087] In some embodiments, the vehicle key recognition module can be used to authenticate the car's electronic key. Optionally, when an emergency power supply is connected to the vehicle, the vehicle key recognition module can actively search for the key via Bluetooth. Figure 6 The system detects the phone key and verifies its legitimacy. If the vehicle key recognition module determines the phone key is invalid, the method ends. If the vehicle key recognition module detects the phone key is valid, the phone can send vehicle control commands to the vehicle.

[0088] In some embodiments, after the vehicle key recognition module determines that the electronic car key is legitimate and that it is powered by an emergency power supply, it can recognize the unlock command received from the electronic car key as an unlock command and send this command to the vehicle's left front door module via the LIN line. The vehicle's left front door module, in response to the unlock command, can unlock the vehicle. Optionally, when the vehicle's left front door module unlocks the vehicle, it may include unlocking the drive left front door lock and electrically releasing the door handle.

[0089] The vehicle lock control method proposed in this application embodiment can unlock the vehicle by recognizing the unlocking and locking functions of the car electronic key as the same button when unlocking the car door in emergency power supply mode. This unlocks other functions of the vehicle and avoids the problem that the car electronic key cannot send the unlocking command to unlock the car normally when unlocking the car door in emergency power supply mode. This allows users to solve the problem of unlocking the vehicle in emergency power supply mode more conveniently and seamlessly.

[0090] The method embodiments of this application have been described in detail above. Based on the above, this application also proposes a vehicle lock control system, which will be discussed below in conjunction with... Figure 7 The system embodiments of this application are described in detail below. It should be understood that the descriptions of the method embodiments above correspond to the descriptions of the system embodiments; therefore, any parts not described in detail can be referred to the foregoing method embodiments.

[0091] Figure 7 This application provides a vehicle lock control system 700, which may include: a judgment module 710, a receiving module 720, and a control module 730.

[0092] The judgment module 710 is used to determine whether the vehicle is in emergency power supply mode;

[0093] The receiving module 720 is used to receive vehicle control commands sent by the car electronic key;

[0094] The control module 730 is used to recognize the vehicle control command as an unlock command and unlock the vehicle when the vehicle is in emergency power supply mode.

[0095] When the vehicle is powered by an emergency power source, it is in emergency power supply mode. Vehicle control commands include unlock and lock commands, and the car's electronic key sends unlock and lock commands using the same button.

[0096] Optionally, when the vehicle is in emergency power supply mode, the control module 730 can also be used to unlock the left front door lock.

[0097] Optionally, the receiving module 720 can also be used to authenticate the electronic car key before receiving vehicle control commands sent by the electronic car key. If the authentication of the electronic car key is successful, a connection is established with the electronic car key, and the vehicle control commands sent by the electronic car key are received; otherwise, if the authentication of the electronic car key fails, a connection cannot be established with the electronic car key.

[0098] Optionally, when the vehicle is in emergency power supply mode, the receiver module 720 can also be used to actively search for the car's electronic key via Bluetooth and authenticate the car's electronic key.

[0099] Optionally, the judgment module 710 can also be used to determine whether the vehicle is in emergency power supply mode based on a first condition, wherein the first condition includes the vehicle's power supply voltage being lower than a first threshold. When the power supply voltage is lower than the first threshold, the vehicle is powered by an emergency power supply. The first threshold is a value greater than or equal to 12V.

[0100] Optionally, the control module 730 can also be used to recognize the vehicle control command as an unlocking command when the vehicle is in emergency power supply mode, and to unlock the door locks and release the door handles.

[0101] Optionally, the control module 730 can also be used to recognize the locking command as an unlocking command and unlock the vehicle when the vehicle is in emergency power supply mode.

[0102] like Figure 8 As shown in the embodiments, this application also proposes a car that may include the vehicle lock control system mentioned in the above embodiments.

[0103] In addition, this application also proposes a computer-readable storage medium storing a computer program.
