[0022] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0023] A vehicle door unlocking method and device according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0024] Figure 1 A vehicle door unlocking method provided by an embodiment of the present application is as follows: Figure 1 As shown, the method includes:

[0025] S101, obtaining the current state of the vehicle through the domain controller;

[0026] S102, if the current state of the vehicle indicates that the vehicle is abnormal, obtaining the physiological state of the passenger in the vehicle cabin;

[0027] S103: If the physiological state of the occupant in the vehicle cabin matches the preset unlocking physiological state, and it is determined that the domain controller fails to unlock the door electronic lock, an unlocking instruction is sent to the door electronic lock to unlock the door electronic lock.

[0028] It can be understood that the door unlocking method provided in this example is applied to a passive safety controller (PSC), which is arranged on a vehicle, and a door electronic lock and a domain controller are also arranged in the vehicle, and the passive safety controller is connected to the door electronic lock and the domain controller of the vehicle respectively, and the above-mentioned vehicles include vehicles with automatic driving or intelligent driving (including vehicles with passenger functions (such as cars, buses, buses, minibuses, etc.), vehicles with cargo functions (such as ordinary trucks, vans, trailers, closed trucks, tank trucks, flatbed trucks, container trucks, dump trucks, trucks with special structures), special vehicles Vehicles (such as logistics distribution vehicles, automatic guided vehicles AGV, patrol cars, cranes, hoists, excavators, bulldozers, forklifts, rollers, loaders, off-road engineering vehicles, armored engineering vehicles, sewage treatment vehicles, sanitation vehicles, vacuum trucks, floor washing vehicles, sprinkler trucks, sweeping robots, food delivery robots, shopping guide robots, lawn mowers, golf carts, etc.), vehicles with entertainment functions (such as entertainment vehicles, amusement park automatic driving devices, balance cars, etc.), rescue vehicles (such as fire trucks, ambulances, power repair vehicles, engineering rescue vehicles, etc.), etc.

[0029] In some examples, the passive safety controller obtains the current state of the vehicle through the domain controller. If the current state of the vehicle is normal, the subsequent process is stopped; if the current state of the vehicle indicates that there is an abnormality in the vehicle, the physiological state of the occupants in the vehicle's cabin is obtained.

[0030] It is understandable that when there is an abnormality in the vehicle, it may affect the safety of the occupants in the vehicle's cabin. In order to avoid the problem that the occupants and people outside the vehicle are unable to open the door when rescue is needed due to the electronic door lock being locked, resulting in delayed rescue, this example obtains the physiological state of the occupants in the vehicle's cabin when the current state of the vehicle indicates that the vehicle has an abnormality.

[0031] Furthermore, this example will preset an unlocking physiological state, which is a pre-set state of the driver and passenger; illustratively, the above-mentioned preset unlocking physiological state includes but is not limited to: a coma state, an injured state, etc.

[0032] After obtaining the physiological state of the occupant in the vehicle's cabin, this example will compare the physiological state of the occupant with the above-mentioned preset unlocking physiological state. If the physiological state of the occupant in the vehicle's cabin matches the preset unlocking physiological state, it indicates that the occupant is currently in physiological discomfort and the electronic door lock needs to be unlocked so that relevant personnel can rescue the occupant.

[0033] Based on the above principles, at this time, when the physiological state of the driver and passenger matches the above-mentioned preset unlocking physiological state, this example will determine whether the domain controller fails to unlock the door electronic lock. If the domain controller successfully unlocks the door electronic lock, the door electronic lock is in an unlocked state, and the passive safety controller does not need to send an unlock command to the door electronic lock; if the domain controller fails to unlock the door electronic lock and the door electronic lock is in a locked state, the passive safety controller sends an unlock command to the door electronic lock to unlock the door electronic lock.

[0034] According to the technical solution provided by the embodiment of the present application, the current state of the vehicle is obtained through the domain controller; if the current state of the vehicle indicates that the vehicle is abnormal, the physiological state of the driver and passenger in the cockpit of the vehicle is obtained; if the physiological state of the driver and passenger in the cockpit of the vehicle matches the preset unlocking physiological state, and it is determined that the domain controller fails to unlock the door electronic lock, an unlocking instruction is sent to the door electronic lock to unlock the door electronic lock, wherein the current state of the vehicle is obtained through the domain controller, and if an abnormality is detected in the vehicle, the physiological state of the driver and passenger in the vehicle is obtained in a targeted manner. The physiological state of the driver and passenger is obtained after the abnormality of the vehicle is detected, which avoids unnecessary physiological state monitoring, reduces the waste of system resources, and improves the accuracy of monitoring. In addition, by matching the physiological state of the driver and passenger with the preset unlocking physiological state, it is possible to accurately identify whether the driver and passenger is in the unlocking physiological state. When the physiological state of the driver and passenger matches the preset unlocking physiological state, and the domain controller fails to try to unlock the door electronic lock, it indicates that the driver and passenger is in the unlocking physiological state, and the system will further send an unlocking instruction through the passive safety controller. This double insurance mechanism ensures that in the event of an emergency with an abnormal vehicle, the electronic door lock can be unlocked in time, allowing the driver and passengers to leave the vehicle in time, and external rescue personnel can intervene quickly to maximize the safety of the driver and passengers. Ultimately, this solution effectively improves the safety and emergency response capabilities of the vehicle through intelligent monitoring and multiple unlocking mechanisms, reduces the risks caused by misoperation or equipment failure, ensures that the driver and passengers can receive timely protection in an emergency, and avoids the problem in related technologies that when the vehicle is abnormal, the domain controller fails to unlock the electronic door lock, posing a safety hazard.

[0035] In some embodiments, Figure 2 As shown, the current status of the vehicle is obtained through the domain controller, including:

[0036] S201, receiving the current state of the vehicle transmitted by the domain controller, and if the current state of the vehicle transmitted by the domain controller includes a collision signal and / or an airbag signal, determining that the vehicle is abnormal;

[0037] S202. Receive the current state of the vehicle transmitted by the domain controller according to a preset period. If the current state of the vehicle transmitted by the domain controller is not received within the preset period, determine that the vehicle is abnormal.

[0038] In the solution provided in this example, the passive safety controller is communicatively connected with the domain controller, wherein when the vehicle collides or flips over, the domain controller generates a collision signal and a flip signal, and when the vehicle airbag is triggered, the domain controller generates an airbag signal.

[0039] The domain controller will periodically transmit the current state of the vehicle to the passive safety controller. When the current state transmitted by the domain controller contains a collision signal, it indicates that the vehicle has a collision anomaly. When the current state transmitted by the domain controller contains an airbag signal, it indicates that the vehicle has an airbag deployment anomaly. When the current state transmitted by the domain controller contains a rollover signal, it indicates that the vehicle has a rollover anomaly. Based on the above principle, this example will receive the current state of the vehicle transmitted by the domain controller. If the current state of the vehicle transmitted by the domain controller contains a collision signal and / or an airbag signal, it is determined that the vehicle has an anomaly.

[0040] It is understandable that relevant technicians can also set other abnormal signals (other abnormal signals besides collision signals, airbag signals, and rollover signals). If the current state of the vehicle transmitted by the domain controller includes an abnormal signal, it is determined that there is an abnormality with the vehicle; if the current state of the vehicle transmitted by the controller does not include an abnormal signal, it is determined that there is no abnormality with the vehicle.

[0041] Among them, the domain controller will periodically transmit the current status of the vehicle to the passive safety controller, that is, the passive safety controller will receive the current status of the vehicle transmitted by the domain controller according to the preset period. If the passive safety controller does not receive the current status of the vehicle transmitted by the domain controller within the preset period, it indicates that there is an abnormality in the domain controller itself or an abnormality in the connection between the domain controller and the passive safety controller. At this time, in order to ensure the safety of the driver and passengers, it will be assumed that there is an abnormality in the vehicle (that is, it is determined that there is an abnormality in the vehicle).

[0042] In some examples, if the passive safety controller does not receive the current state of the vehicle transmitted by the domain controller within a preset period, and the current state of the vehicle transmitted by the domain controller indicates that there is no abnormality with the vehicle, it is determined that there is no abnormality with the vehicle.

[0043] According to the technical solution provided in the embodiment of the present application, the current state of the vehicle transmitted by the domain controller is received. If the current state of the vehicle transmitted by the domain controller includes a collision signal and / or an airbag signal, it is determined that the vehicle is abnormal; wherein, the solution ensures that when the vehicle is in a collision or the airbag is deployed, the current state of the vehicle is defined as abnormal, and then the step of obtaining the physiological state of the driver and passenger is performed, which effectively improves the safety and emergency response capabilities of the vehicle, reduces the risks caused by misoperation or equipment failure, and ensures that the driver and passengers can obtain timely protection in an emergency;

[0044] Another scheme of the present scheme receives the current status of the vehicle transmitted by the domain controller according to a preset period. If the current status of the vehicle transmitted by the domain controller is not received within the preset period, it is determined that there is an abnormality with the vehicle. Among them, if the passive safety controller does not receive the current status of the vehicle transmitted by the domain controller within the preset period, it will be assumed that there is an abnormality with the vehicle, which effectively improves the safety and emergency response capabilities of the vehicle, reduces the risks caused by misoperation or equipment failure, and ensures that the driver and passengers can receive timely protection in an emergency.

[0045] In some embodiments, Figure 3 As shown, obtaining the physiological state of the occupant in the vehicle cabin includes:

[0046] S301, issuing a status acquisition request through an interactive system in the vehicle;

[0047] S302: If no response information is received from the driver or passenger in response to the status acquisition request within a preset waiting time, a camera of the vehicle is called to acquire the physiological status of the driver or passenger.

[0048] Specifically, when the vehicle obtains the physiological state of the driver and passenger, in order to avoid the privacy leakage of the driver and passenger caused by directly obtaining the physiological state, this example sends a status acquisition request through the interactive system in the vehicle; the interactive system includes but is not limited to: an interactive screen in the cockpit and an audio device in the cockpit. Exemplarily, the passive safety controller sends a status acquisition request through the interactive screen and / or the audio device.

[0049] It is understandable that if the driver and passenger are currently experiencing physical discomfort, such as coma or other loss of consciousness, it is impossible to promptly obtain response information from the request for status acquisition; based on this principle, if the passive safety controller does not receive response information from the driver and passenger in response to the status acquisition request within the preset waiting time, in order to avoid safety issues caused by the driver and passenger's current physical discomfort, such as coma or other loss of consciousness, and the inability to respond in time, this example will promptly call the vehicle's camera to obtain the driver and passenger's physiological state.

[0050] The above-mentioned shooting device includes but is not limited to: one of the driver monitoring system (DMS) and the interior monitoring system (IMS) set in the cockpit; illustratively, the passive safety controller recognizes the facial state and body posture of the driver and passenger through the DMS and / or IMS; it can be understood that the passive safety controller recognizes the physiological state through facial recognition and body posture, specifically, through the facial state, it can be judged whether the driver and passenger in the car is in a coma / awake state, and the degree of pain of the driver and passenger in the car, so as to accurately obtain the physiological state; the passive safety controller determines whether the driver and passenger in the car has self-awareness through body posture recognition. It can be understood that the facial state and body posture can be improved through simulation testing, database establishment, and simulation testing during the research and development process to improve the recognition accuracy, improve the rescue accuracy, and thus accurately obtain the physiological state.

[0051] It can be understood that if the passive safety controller receives a response message from the occupant to the status acquisition request within the preset waiting time, and the received response message indicates that the occupant is currently feeling physiological discomfort (for example, the occupant expresses through the microphone that he or she is feeling physiological discomfort), the passive safety controller will also obtain the physiological state of the occupant in the vehicle's cabin; if the passive safety controller receives a response message from the occupant to the status acquisition request within the preset waiting time, and the received response message indicates that the occupant is in a good state (for example, the occupant expresses through the microphone that he or she is in a good state), the passive safety controller will not obtain the physiological state of the occupant in the vehicle's cabin.

[0052] According to the technical solution provided in the embodiment of the present application, a status acquisition request is issued through the interactive system in the vehicle; if no response information is received from the driver and passenger in response to the status acquisition request within the preset waiting time, the vehicle's camera is called to acquire the driver and passenger's physiological state, thereby achieving active and timely intervention to acquire the driver and passenger's physiological state in the vehicle's cabin when the driver and passenger is currently physically unwell, comatose or otherwise loses consciousness and is unable to respond in time, thereby improving the driver and passenger's safety.

[0053] In some embodiments, Figure 4 As shown, obtaining the physiological state of the occupant in the vehicle cabin includes:

[0054] S401, obtaining the current driving state of the vehicle;

[0055] S402: If the current driving state of the vehicle is a stationary state, obtain the physiological state of the occupant in the vehicle cabin.

[0056] Specifically, if the electronic lock of the vehicle door is unlocked while the vehicle is driving, it may cause the driver and passengers to fall from the moving vehicle and cause injury to the driver and passengers. In order to avoid the above problem, this example obtains the current driving state of the vehicle. If the current driving state of the vehicle is stationary, the physiological state of the driver and passengers in the vehicle's cabin is obtained; if the current driving state of the vehicle is in motion, the physiological state of the driver and passengers in the vehicle's cabin will not be obtained, thereby avoiding the problem of waste of resources caused by ineffective acquisition of the physiological state of the driver and passengers in the vehicle's cabin.

[0057] It can be understood that the passive safety controller determines whether the current driving state of the vehicle is a stationary state by obtaining the vehicle's driving speed; specifically, if the vehicle's driving speed is 0, it is determined that the current driving state of the vehicle is a stationary state; when the vehicle's driving speed is not 0, it is determined that the current driving state of the vehicle is a moving state.

[0058] According to the technical solution provided in the embodiment of the present application, the current driving state of the vehicle is obtained; if the current driving state of the vehicle is a stationary state, the physiological state of the occupant in the vehicle's cabin is obtained, thereby ensuring that the physiological state of the occupant in the vehicle's cabin is obtained only when the vehicle is stationary, thereby avoiding the problem of waste of resources caused by ineffective acquisition of the physiological state of the occupant in the vehicle's cabin when the vehicle is moving.

[0059] In some embodiments, Figure 5 As shown, before obtaining the physiological state of the occupant in the vehicle cabin, the method further includes:

[0060] S501, determining whether the vehicle door electronic lock is in a locked state;

[0061] S502: If the vehicle door electronic lock is in a locked state, it is determined that the domain controller fails to unlock the vehicle door electronic lock.

[0062] Specifically, if there is no abnormality in the domain controller itself, or there is no abnormality in the connection between the domain controller and the vehicle door electronic lock, the domain controller can successfully unlock the vehicle door electronic lock.

[0063] Based on the above principle, this example will determine whether the door electronic lock is in a locked state. If the door electronic lock is in a locked state, it is determined that the domain controller has failed to unlock the door electronic lock; if the door electronic lock is in an unlocked state, it is determined that the domain controller has successfully unlocked the door electronic lock.

[0064] It can be understood that if it is determined that the domain controller successfully unlocks the door electronic lock, the passive safety controller does not need to send an unlock command to the door electronic lock; if the physiological state of the occupant in the vehicle's cabin matches the preset unlocking physiological state, and it is determined that the domain controller fails to unlock the door electronic lock, the passive controller will send an unlock command to the door electronic lock to unlock the door electronic lock and ensure the safety of the occupant.

[0065] In order to better understand the present solution, this embodiment provides a more specific example for illustration. In this implementation, the passive safety controller is connected to the door electronic lock via a hard line (ensuring the stability of the communication connection between the door electronic lock and the passive safety controller, so that the communication connection between the door electronic lock and the passive safety controller is not affected by the environment), and the passive safety controller is also connected to the domain controller, such as Figure 6 As shown, the domain controller will report the current status of the vehicle according to the preset period. If the current status of the vehicle reported by the domain controller indicates that there is no abnormality with the vehicle (no sudden situations such as collision, rollover or airbag deployment), the passive safety control maintains the existing mode, and does not execute a request to the cockpit domain controller, DMS, IMS (collectively referred to as camera devices) to obtain the physiological status of the driver and passengers in the vehicle's cabin, and does not send an unlocking command to the door electronic lock.

[0066] It can be understood that if the domain controller reports the current status of the vehicle within the preset period, so that the interrupt period (TBD) for the domain controller to obtain the current status is less than the preset period (receiving period) of the passive safety controller, the domain controller maintains the existing mode, does not execute the request to send to the cockpit domain controller, DMS, I MS to obtain the physiological status of the driver and passengers in the vehicle's cabin, and does not send an unlocking command to the door electronic lock. If the interrupt period (TBD) of the domain controller is greater than or equal to the preset period (receiving period) of the passive safety controller, it executes the request to send to the cockpit domain controller, DMS, I MS to obtain the physiological status of the driver and passengers in the vehicle's cabin.

[0067] It can be understood that in order to improve the safety of the driver and passengers, this example will also obtain the current driving state of the vehicle. If the current driving state of the vehicle is not in a stationary state, the existing mode will be maintained, and no request will be sent to the cockpit domain controller, DMS, or IMS to obtain the physiological state of the driver and passengers in the vehicle's cabin, and no unlocking command will be sent to the door electronic lock; if the current driving state of the vehicle is stationary, a request will be sent to the cockpit domain controller, DMS, or IMS to obtain the physiological state of the driver and passengers in the vehicle's cabin.

[0068] It can be understood that if the vehicle's door electronic lock is already in an unlocked state, the passive safety controller maintains the existing mode, does not execute a request to the cockpit domain controller, DMS, or I MS to obtain the physiological state of the driver and occupants in the vehicle's cabin, and does not send an unlocking command to the door electronic lock; if the vehicle's door electronic lock is in a locked state, a request to the cockpit domain controller, DMS, or I MS to obtain the physiological state of the driver and occupants in the vehicle's cabin is executed.

[0069] It can be understood that the solution provided in this example will also send a status acquisition request through the interactive system in the vehicle; if no response information sent by the driver and passenger in response to the status acquisition request is received within the preset waiting time, the vehicle's camera device is called to obtain the driver and passenger's physiological state, and when the physiological state meets the preset unlocking physiological state, an unlocking instruction is sent to the door electronic lock to unlock the door electronic lock; if the driver and passenger sends a response information, and the response information indicates that the driver and passenger's physiological state is good, the unlocking instruction will not be sent to the door electronic lock;

[0070] It can be understood that sending a request to the cockpit domain controller, DMS, and IMS to obtain the physiological state of the driver and passengers in the cockpit of the vehicle includes: identifying the facial state and body posture of the driver and passengers, judging the physiological state of the driver and passengers in the car based on the facial state and body posture, and determining whether to execute subsequent steps based on the physiological state of the driver and passengers in the car. Among them, the current physical sign information of the physiological state of the driver and passengers in the car is specifically judged by facial recognition and body posture. Through facial state recognition, it can be judged whether the driver and passengers in the car are in a coma / awake state, and the degree of pain of the driver and passengers in the car; through body posture recognition, it can be judged whether the driver and passengers in the car have self-awareness. Facial state and body posture can be improved through simulation testing, database establishment, and simulation testing during the research and development process to improve recognition accuracy and rescue accuracy.

[0071] In some examples, such as Figure 7 As shown, ① the domain controller periodically obtains the current state, speed state, and four-door electronic lock state of the vehicle and reports them to the PSC; ② when the PSC fails to obtain the current state uploaded by the domain controller within the specified period, it determines whether the vehicle is in a stationary state; ③ if the vehicle is in a stationary state (when the speed is reset to zero, the vehicle is determined to be in a stationary state), it determines whether the door electronic lock state is unlocked; ④ if the vehicle door electronic lock state is locked, a request for judging the physiological state of the occupant in the vehicle is sent to the cockpit domain controller CDC; ⑤ if the request for judging the physiological state of the occupant in the vehicle is not responded to, the in-vehicle facial recognition DMS / in-vehicle camera I MS is called to judge the physiological state of the occupant in the vehicle; ⑥ if the physiological state of the occupant in the vehicle is judged to meet the preset unlocking physiological state conditions, the PSC issues a command to unlock the four-door electronic locks.

[0072] According to the technical solution provided in the embodiment of the present application, it is determined whether the vehicle door electronic lock is in a locked state; if the vehicle door electronic lock is in a locked state, it is determined that the domain controller has failed to unlock the vehicle door electronic lock. The above method is used to accurately determine whether there is an abnormality in the domain controller.

[0073] In some embodiments, Figure 8 As shown, the method also includes:

[0074] S801, receiving a low-battery warning of a power supply battery, where the power supply battery is used to power a passive safety controller;

[0075] S802: Send a charging request to the domain controller, so that the domain controller charges the power supply battery through the battery management system.

[0076] In the solution provided in this example, the passive safety controller is independently provided with a power supply battery. When the power supply battery is low on power, the power supply battery will send a low power warning to the passive safety controller. After receiving the low power warning transmitted by the power supply battery, the passive safety controller will send a charging request to the domain controller, so that the domain controller charges the power supply battery through the battery management system (BMS) until the power supply battery is charged to a preset value (or is fully charged). Fig. 9 shown.

[0077] It can be understood that when a power supply battery fails, causing the current and voltage supplied to the passive safety controller to be lower than the specified current and voltage, the passive safety controller will issue a fault prompt to alert the passengers in the car, and the domain controller will inhibit the function of the passive safety controller (the passive safety controller will stop working). When the power supply battery fault is cleared and the current and voltage of the passive safety controller meet the specified current and voltage, the domain controller contact inhibition will cause the passive controller to resume working.

[0078] According to the technical solution provided in the embodiment of the present application, a low-battery warning of a power supply battery is received, and the power supply battery is used to power the passive safety controller; a charging request is sent to the domain controller, so that the domain controller charges the power supply battery through the battery management system, thereby ensuring that the power supply battery has sufficient power, thereby ensuring the normal operation of the passive safety controller, and the passive safety controller is powered by the power supply battery and will not be affected by the BMS status. In specific scenarios, when the BMS fails or becomes disabled, the functions of the passive safety controller can also work normally.

[0079] In some embodiments, Fig.10 As shown, after sending an unlock command to the vehicle door electronic lock to unlock the vehicle door electronic lock, the method further includes:

[0080] S1001, generating an online help signal, obtaining a preset emergency contact method, and sending the online help signal to the emergency contact method;

[0081] S1002: Generate an offline help signal, and send the offline help signal through the vehicle's audio and video equipment.

[0082] Specifically, when the passive safety controller unlocks the electronic door lock, it indicates that the occupants in the vehicle are currently feeling unwell and need rescue. In order to ensure that rescue personnel can rescue the occupants in a timely and accurate manner, the passive safety controller provided in this example will simultaneously generate an online help signal and an offline help signal.

[0083] Among them, after the passive safety controller generates an online help signal, it will obtain the pre-set emergency contact information and send the online help signal to the emergency contact information, so that the contact person corresponding to the emergency contact information can be informed that the driver and passengers need rescue and launch rescue operations for the drivers and passengers in time.

[0084] Among them, after the passive safety controller generates an offline help signal, it will send an offline help signal through the vehicle's audio and video equipment, so that rescue personnel near the vehicle can rescue the driver and passengers in time to avoid delaying the rescue opportunity.

[0086] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0087] The following is an embodiment of the device of the present application, which can be used to execute the embodiment of the method of the present application. For details not disclosed in the embodiment of the device of the present application, please refer to the embodiment of the method of the present application.

[0088] This embodiment also provides a door unlocking device, such as Fig.11 As shown, the device comprises:

[0089] The vehicle module 1101 is used to obtain the current state of the vehicle through the domain controller;

[0090] The driving module 1102 is used to obtain the physiological state of the driving object in the cabin of the vehicle when the current state of the vehicle indicates that the vehicle is abnormal;

[0091] The unlocking module 1103 is used to send an unlocking instruction to the door electronic lock to unlock the door electronic lock when the physiological state of the occupant in the vehicle cabin matches the preset unlocking physiological state and determines that the domain controller fails to unlock the door electronic lock.

[0092] In some examples, the driving module 1102 is also used to receive the current state of the vehicle transmitted by the domain controller. If the current state of the vehicle transmitted by the domain controller includes a collision signal and / or an airbag signal, it is determined that there is an abnormality with the vehicle. The driving module 1102 is also used to receive the current state of the vehicle transmitted by the domain controller according to a preset period. If the current state of the vehicle transmitted by the domain controller is not received within the preset period, it is determined that there is an abnormality with the vehicle.

[0093] In some examples, the driving module 1102 is also used to issue a status acquisition request through an interactive system in the vehicle; if no response information is received from the driving object in response to the status acquisition request within a preset waiting time, the vehicle's camera is called to obtain the physiological state of the driving object.

[0094] In some examples, the driving module 1102 is also used to obtain the current driving state of the vehicle; if the current driving state of the vehicle is a stationary state, the physiological state of the driving object in the cabin of the vehicle is obtained.

[0095] In some examples, the driving module 1102 is further used to determine whether the vehicle door electronic lock is in a locked state; if the vehicle door electronic lock is in a locked state, it is determined that the domain controller has failed to unlock the vehicle door electronic lock.

[0096] In some examples, the driving module 1102 is also used to receive a low-battery warning of a power supply battery, which is used to power the passive safety controller; and send a charging request to the domain controller so that the domain controller charges the power supply battery through a battery management system.

[0097] In some examples, the unlocking module 1103 is also used to generate an online help signal, obtain a pre-set emergency contact method, and send the online help signal to the emergency contact method; generate an offline help signal, and send the offline help signal through the vehicle's audio and video equipment.

[0098] According to the technical solution provided by the embodiment of the present application, the door unlocking device provided by the present embodiment obtains the current state of the vehicle through the domain controller; if the current state of the vehicle indicates that the vehicle is abnormal, the physiological state of the driver and passenger in the vehicle's cabin is obtained; if the physiological state of the driver and passenger in the vehicle's cabin matches the preset unlocking physiological state, and it is determined that the domain controller fails to unlock the door electronic lock, an unlocking instruction is sent to the door electronic lock to unlock the door electronic lock, wherein the current state of the vehicle is obtained through the domain controller, and if an abnormality is detected in the vehicle, the physiological state of the driver and passenger in the vehicle is obtained in a targeted manner. Obtaining the physiological state of the driver and passenger after detecting that the vehicle is abnormal avoids unnecessary physiological state monitoring, reduces the waste of system resources, and improves the accuracy of monitoring. In addition, by matching the physiological state of the driver and passenger with the preset unlocking physiological state, it is possible to accurately identify whether the driver and passenger is in the unlocking physiological state. When the physiological state of the driver and passenger matches the preset unlocking physiological state, and the domain controller fails to try to unlock the door electronic lock, the system will further send an unlocking instruction through the passive safety controller. This double insurance mechanism ensures that in the event of an emergency with an abnormal vehicle, the electronic door lock can be unlocked in time, allowing the driver and passengers to leave the vehicle in time, and external rescue personnel can intervene quickly to maximize the safety of the driver and passengers. Ultimately, this solution effectively improves the safety and emergency response capabilities of the vehicle through intelligent monitoring and multiple unlocking mechanisms, reduces the risks caused by misoperation or equipment failure, ensures that the driver and passengers can receive timely protection in an emergency, and avoids the problem in related technologies that when the vehicle is abnormal, the domain controller fails to unlock the electronic door lock, posing a safety hazard.
