Description

Technical Field

[0001] This application relates to the field of anti-theft, and more particularly to an active anti-theft method for vehicles, an active anti-theft device for vehicles, and a vehicle lock. Background Technology

[0002] A typical car anti-theft system is designed to prevent the theft of the vehicle itself or items inside. It primarily includes preventing unauthorized personnel from entering the vehicle, preventing unauthorized personnel from starting the vehicle, and locating and tracing the vehicle after it has been stolen. Existing car anti-theft systems mainly employ a series of passive anti-theft technologies such as door locks, steering locks, and chip-based anti-theft locks. These systems prevent theft by preventing entry into the vehicle's interior, and the anti-theft function of these locks requires human operation.

[0003] Besides manual locking, most vehicles use remote or timed locking, but this introduces new risks. For example, criminals can use signal jamming to prevent successful locking; car owners may be unable to operate the key fob due to carrying items, or forget to do so; or the owner may temporarily leave the vehicle without taking the keys. These gaps in vehicle management create opportunities for theft, providing criminals with avenues for theft and time to exploit them. During this period, the risk of theft cannot be controlled.

[0004] Therefore, a proactive anti-theft solution is needed to address the issues of left-behind theft lanes in vehicles and the uncontrolled duration of these lanes. Summary of the Invention

[0005] The purpose of this invention is to provide a vehicle active anti-theft method, a vehicle active anti-theft device, and a vehicle lock, thereby solving at least one of the aforementioned technical problems.

[0006] This invention provides the following solution:

[0007] According to one aspect of the present invention, a vehicle active anti-theft method is provided, the vehicle active anti-theft method comprising:

[0008] Step 1: Check if there are any people inside the car and check if any car keys have been left inside the car.

[0009] Step 2: If no one is detected inside the vehicle, control the doors to lock automatically.

[0010] Step 3: If the car key is detected as being left inside the vehicle during automatic locking, the lock will be opened based on the occupant information.

[0011] Step 4: If the automatic locking system detects that the car key was not left inside the car, then the lock will be opened based on the car key information.

[0012] Furthermore, the automatic door locking control also includes: detecting whether the automatic door locking is successful;

[0013] If the locking is successfully detected, proceed to step 3 or step 4;

[0014] If locking fails, a vehicle anti-theft warning message will be sent.

[0015] Furthermore, it also includes:

[0016] Obtain the identification features of the occupants of the vehicle and the identification features of the car key;

[0017] Register the identities of the people in the vehicle and their corresponding seat information based on their personal identification features;

[0018] Register vehicle key unlocking permissions based on vehicle key recognition features;

[0019] Perform the unlocking process in step 4 based on the instructions from the car key with unlocking authority.

[0020] Furthermore, the unlocking based on personnel information includes:

[0021] Access the car owner user database;

[0022] The vehicle owner user database includes preset vehicle owner users;

[0023] Register the current vehicle's first-level user and second-level user based on the identity of the occupants and their corresponding seat information;

[0024] If the person currently in the driver's seat is the vehicle owner, then the person registered in the driver's seat is the first-level user of the current vehicle.

[0025] Based on being in the same vehicle as the current vehicle's first-level user, the person not in the driver's seat is registered as a second-level user of the current vehicle, who is subordinate to the current vehicle's first-level user.

[0026] Based on whether the person requesting unlocking is the current vehicle's first-level or second-level user, proceed with step 3 to unlock the vehicle.

[0027] Furthermore, the process of registering the current vehicle's first-level and second-level users based on the identities of the occupants and their corresponding seat information includes:

[0028] If the person in the driver's seat changes to another vehicle owner user, then the current vehicle's first-level user is refreshed, and based on whether they are in the same vehicle as the current first-level user, the person not in the driver's seat is refreshed as the current vehicle's second-level user under the current vehicle's first-level user.

[0029] If the person in the non-driver's seat changes, the person in the non-driver's seat will be updated to the second-level user of the current vehicle, based on the person in the same vehicle as the first-level user of the current vehicle.

[0030] If the person in the driver's seat changes to someone other than the vehicle owner, then the registration record of the current second-level user of the vehicle will be deleted.

[0031] Furthermore, the process of registering the current vehicle's first-level and second-level users based on the identities of the occupants and their corresponding seat information also includes:

[0032] Obtain vehicle driving status information;

[0033] The registration, refresh, and deletion of records for the current vehicle's second-level user, or the current vehicle's first-level user and the current vehicle's second-level user, are performed while the vehicle is in motion.

[0034] Furthermore, the process of registering the current vehicle's first-level and second-level users based on the identities of the occupants and their corresponding seat information also includes:

[0035] If step 4 is performed, then the registration records of the current vehicle's second-level user, or the current vehicle's first-level user and the current vehicle's second-level user, will be deleted.

[0036] Furthermore, the automatic locking of the vehicle doors also includes: synchronously activating monitoring of the vehicle status;

[0037] Register initial vehicle status information;

[0038] The initial vehicle status information includes information on vehicle location and engine operating status;

[0039] If the deviation between the current vehicle status and the initial vehicle status exceeds a preset threshold, preset anti-theft measures will be taken.

[0040] The preset anti-theft measures include controlling the vehicle to enter an abnormal driving state and sending a vehicle theft warning message.

[0041] According to a second aspect of the present invention, an active vehicle anti-theft device is provided, the active vehicle anti-theft device comprising:

[0042] The detection module is used to detect whether there are people inside the vehicle and whether the car keys have been left inside the vehicle.

[0043] The automatic door locking module is used to automatically lock the doors if no one is detected inside the vehicle.

[0044] The first unlocking module is used to unlock the car based on the occupant information if the car key is detected as being left inside the car during automatic locking.

[0045] The second unlocking module is used to unlock the car if the car key is not left inside the car when the automatic locking occurs, based on the car key information.

[0046] According to three aspects of the present invention, a vehicle lock is provided, the vehicle lock including an active anti-theft device for the vehicle;

[0047] The steps of the vehicle lock to perform the vehicle active anti-theft method.

[0048] The above solution achieves the following beneficial technical effects:

[0049] This application automatically locks the doors and trunk when the vehicle is unoccupied and in a management vacuum, and automatically closes windows and sunroofs, thus cutting off theft routes in a timely manner and minimizing the time that theft can occur.

[0050] This application detects the failure of measures to cut off burglary passages by checking the status of locked doors and closed windows, and issues a timely warning, thus giving people a chance to remedy the situation.

[0051] This application addresses the scenario where the car key is left inside the vehicle during automatic locking. It strictly distinguishes the unlocking permissions of individuals, ensuring that the "proactive anti-theft" measures are precisely targeted at reasonable individuals, rather than the car owner or their close friends.

[0052] This application extends the active anti-theft measures from preventing intrusion into the vehicle's interior to preventing the vehicle from being illegally started or moved abnormally, thereby expanding the protective effect of active anti-theft to remote monitoring of the vehicle and recovery of stolen vehicles.

[0057] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] Figure 1 This is a flowchart of a vehicle active anti-theft method provided by one or more embodiments of the present invention.

[0059] like Figure 1 The active vehicle anti-theft methods shown include:

[0060] Step 1: Check if there are any people inside the car and check if any car keys have been left inside the car.

[0061] Step 2: If no one is detected inside the vehicle, control the doors to lock automatically.

[0062] Step 3: If the car key is detected as being left inside the vehicle during automatic locking, the lock will be opened based on the occupant information.

[0063] Step 4: If the automatic locking system detects that the car key was not left inside the car, then the lock will be opened based on the car key information.

[0064] The above solution achieves the following beneficial technical effects:

[0065] This application automatically locks the doors and trunk when the vehicle is unoccupied and in a management vacuum, and automatically closes windows and sunroofs, thus cutting off theft routes in a timely manner and minimizing the time that theft can occur.

[0066] This application detects the failure of measures to cut off burglary passages by checking the status of locked doors and closed windows, and issues a timely warning, thus giving people a chance to remedy the situation.

[0067] This application addresses the scenario where the car key is left inside the vehicle during automatic locking. It strictly distinguishes the unlocking permissions of individuals, ensuring that the "proactive anti-theft" measures are precisely targeted at reasonable individuals, rather than the car owner or their close friends.

[0068] This application extends the active anti-theft measures from preventing intrusion into the vehicle's interior to preventing the vehicle from being illegally started or moved abnormally, thereby expanding the protective effect of active anti-theft to remote monitoring of the vehicle and recovery of stolen vehicles.

[0069] Specifically, cameras can be installed inside the vehicle to sense the presence of people and car keys. These cameras can also be used to recognize facial features, identifying registered individuals and their seats. External cameras can be used for facial recognition. Remote-controlled car keys can typically also sense their location via radio frequency antennas and decode their ID codes and keys. If the key's characteristics are recorded in the vehicle's pre-stored database, it can be determined whether the received remote unlocking information comes from an authorized key.

[0070] A motor or magnetic switch can be installed on the car door to control the door lock. The power supply is controlled by the vehicle's infotainment system or vehicle control switch contacts to lock or unlock the door.

[0071] The car door can be equipped with a latch position contact switch, which determines whether the door has been successfully locked based on the position of the latch. If the locking command is executed but the latch is not detected to have reached the preset position to flip the contact potential, the vehicle's infotainment system or control system can determine that the locking has failed.

[0072] Locking the car doors is the primary method of preventing vehicles from entering or exiting. However, vehicle access points include not only the doors but also the trunk, windows, and sunroof. The drive motors for the trunk, windows, and sunroof can be controlled to completely seal them. Position sensors or contacts can also be installed on the trunk, windows, and sunroof to detect whether they are fully closed. The closing of the trunk, windows, and sunroof can be triggered simultaneously with the automatic locking of the doors, or the detection of whether the trunk, sunroof, and windows are fully closed can be performed together with the detection of successful door locking. The trunk also has a lock similar to that on the doors; therefore, the trunk and doors can be considered as devices in the same control circuit, and all access control units on all vehicles can be treated as a unified "lock."

[0073] Generally, when there are people inside the car, whether they are the owner or passengers, it means that the vehicle is still under someone's management, making theft unlikely.

[0074] If no one is inside the vehicle, it can be understood as a vacuum in vehicle management. If the driver or relevant passengers have moved away from the vehicle and have not promptly locked the doors or other access points, the vehicle's normal entry and exit points may become a theft route. Thieves can enter the vehicle and steal valuables or drive it away. During the period when this theft route exists, the door locks and other locks are unable to prevent the thieves from entering.

[0075] Normally, car doors are locked by a person using a car key, commonly via remote key control. However, interference signals can cause the locking process to fail, leaving a way for thieves to steal the car. Thieves sometimes specifically use this method of interfering with the car key's locking mechanism, making the owner believe they have locked the car when they haven't.

[0076] Car owners may also be distracted by carrying many items and forget to lock their doors, leaving an opening for theft.

[0077] In order to prevent the vehicle doors from not being reliably locked when people leave the vehicle, this application uses the absence of people inside the vehicle as the activation condition for active anti-theft, thereby minimizing the time that theft channels remain.

[0078] In real-world scenarios, sometimes car owners take their car keys with them, intending to leave the vehicle for an extended period, while others only leave temporarily and forget their keys inside. In both cases, the car is unoccupied, and leaving the keys inside makes it easier for thieves to steal the vehicle. Therefore, when using proactive anti-theft locks, the possibility of leaving the keys inside should not preclude effectively cutting off theft routes.

[0079] However, the automatic locking mechanism of the anti-theft system also brings the problem of unlocking. Since the car key is left inside the vehicle when the anti-theft system is activated, different unlocking strategies must be adopted depending on whether the car key is currently inside the vehicle.

[0080] When a vehicle is to be unlocked by a person, the exterior camera can be kept active beforehand, allowing for facial recognition to identify the person when they attempt to unlock it. Alternatively, to ensure smooth unlocking, the interior camera can also be kept active to prevent damage to the exterior camera and maintain the vehicle's anti-theft functionality. If the exterior camera malfunctions, the interior camera can compensate by using facial recognition through the window.

[0081] In this embodiment, controlling the automatic locking of the vehicle door further includes: detecting whether the automatic locking of the vehicle door is successful;

[0082] If the locking is successfully detected, proceed to step 3 or step 4;

[0083] If locking fails, a vehicle anti-theft warning message will be sent.

[0084] Specifically, automatic door locking is usually an electrical function, but it also requires mechanical positioning. In other words, the door lock can only be properly locked if the door is closed tightly. Otherwise, the latch will simply pop out, which may not only fail to lock the door successfully, but may also prevent the door from closing.

[0085] A position sensor or signal contact can usually be installed between the latch and the door frame. If the door is fully locked, the potential signal can be reversed, which can then determine whether the door has been successfully locked.

[0086] If the locking mechanism fails to detect successful locking, the vehicle owner should be notified immediately. Since the owner has just left the vehicle and has not gone far, the alarm system can serve as a warning, allowing the owner to take timely remedial action and preventing theft.

[0087] While checking if the car doors are locked, also check if the trunk, windows, sunroof, and other remaining access passages are locked. You can check the door locks and the closure of other passages at the same time.

[0088] In addition to the built-in locks on the windows and sunroof, their drive motors can also maintain the locked state by outputting torque. Therefore, the detection of the closed state of the windows and sunroof is not only performed once during the automatic locking phase. For example, if someone pulls down the window glass with tape, the vehicle will detect that the window is about to be opened again, and the window motor can output torque to counteract the external thief, thus buying time.

[0089] In this embodiment, it also includes:

[0090] Obtain the identification features of the occupants of the vehicle and the identification features of the car key;

[0091] Register the identities of the people in the vehicle and their corresponding seat information based on their personal identification features;

[0092] Register vehicle key unlocking permissions based on vehicle key recognition features;

[0093] Perform the unlocking process in step 4 based on the instructions from the car key with unlocking authority.

[0094] Specifically, to enable facial recognition to distinguish between the "car owner," "passenger," and stranger, it's necessary to pre-register the characteristic information of individuals such as the "car owner" and "passenger." This allows for comparison of facial features during the facial recognition process, identifying whether the person currently using facial recognition is someone who forgot to remove their car keys or their companion. Similarly, the characteristic information of the car key needs to be pre-registered so that when the car key is being unlocked, its signal characteristics can be compared to identify whether the key attempting to unlock the car matches the current vehicle's permissions.

[0095] In this embodiment, unlocking based on personnel information includes:

[0096] Access the car owner user database;

[0097] The vehicle owner user database includes preset vehicle owner users;

[0098] Register the current vehicle's first-level user and second-level user based on the identity of the occupants and their corresponding seat information;

[0099] If the person currently in the driver's seat is the vehicle owner, then the person in the driver's seat is registered as the first-level user of the current vehicle.

[0100] Based on the fact that they are in the same vehicle as the current first-level user, the person who is not in the driver's seat will be registered as a second-level user of the current vehicle under the current first-level user;

[0101] Based on whether the person requesting unlocking is the current vehicle's first-level or second-level user, proceed with step 3 to unlock the vehicle.

[0102] Specifically, the vehicle owner's identification information can be pre-stored on the vehicle's infotainment system or cloud storage. For example, facial recognition or other methods can be used to identify the person currently in the driver's seat and determine if the owner is driving. The current driver can be registered as a Level 1 user. If the owner is driving, other passengers can be considered guests or friends allowed to ride in the vehicle by the owner, and can be defined as "people who will not steal the vehicle." Therefore, these passengers can be temporarily registered as Level 2 users under the Level 1 user.

[0103] At this point, the driver and passengers, as first-level users and second-level users under the current first-level user respectively, can be granted access to the vehicle via facial recognition if they forget to take the car keys and leave the vehicle. However, the person who "forgot to remove the car keys and their companion" happens to be one of these first-level users and second-level users under the current first-level user, resulting in the awkward situation of being locked out. Therefore, proactive theft prevention should target people other than these first-level users and second-level users under the current first-level user.

[0104] In this embodiment, registering the current vehicle's first-level user and second-level user based on the identity of the occupants and their corresponding seat information includes:

[0105] If the person in the driver's seat changes to another vehicle owner, the current vehicle's first-level user is refreshed, and based on whether they are in the same vehicle as the current first-level user, the person not in the driver's seat is refreshed as the current vehicle's second-level user under the current first-level user.

[0106] If the person in the non-driver's seat changes, the person in the non-driver's seat will be updated to the second-level user of the current vehicle, based on the person in the same vehicle as the first-level user of the current vehicle.

[0107] If the person in the driver's seat is changed to a non-owner user, then the registration record of the current second-level user of the vehicle will be deleted.

[0108] Specifically, vehicles typically have more than one owner, such as a married couple jointly owning a car. If the in-car camera detects a change in the driver's seat, with another owner taking over, then the primary user and all secondary users under that primary user need to be re-registered. For example, on the first day, the male homeowner drives with a male colleague, and on the second day, the female homeowner drives with a male friend. Although both the male and female homeowners are car owners and have the highest level of vehicle access, the overlapping and intersecting permissions of their respective secondary users effectively expands the secondary users' access to those outside their primary user group. This means the male homeowner's "male colleague" can access the female homeowner's car, and the "male friend" can access the male homeowner's car. Therefore, the secondary users must be registered under the primary user group within the same car.

[0109] It is unreasonable to lump the male homeowner's "male colleague" and the female homeowner's "male best friend" together as a shared second-level user. Even if neither is involved in theft, it still raises privacy concerns. Therefore, the first-level user should be updated according to who is currently the driver, and the second-level user should be updated accordingly.

[0110] For example, if a vehicle is sold in the used car market, and the records of the first-level user and its subordinate second-level users are still retained, and the new owner does not refresh the second-level user after viewing the vehicle, it is equivalent to opening a theft channel to the original owner's "friends" after the vehicle transaction is completed. Therefore, in order to adapt to the scenario of changing car owners, the second-level user must be registered under the first-level user of the same vehicle.

[0111] For example, if a car owner drives a vehicle and a hotel dispatches a temporary service staff member to ride in the vehicle with the car owner, the temporary service staff member may be a second-level user traveling with the car owner. If the temporary service staff member helps the car owner back to their residence and forgets to remove the key, the temporary service staff member may take the opportunity to return to the vehicle, revealing a vulnerability in access control.

[0112] Therefore, it is necessary to make adaptive changes to the identity and permissions of personnel based on the specific scenario.

[0113] In this embodiment, registering the current vehicle's first-level user and second-level user based on the identity of the occupants and their corresponding seat information also includes:

[0114] Obtain vehicle driving status information;

[0115] Registering, refreshing, or deleting records for the current vehicle's second-level users, or records for both the current vehicle's first-level and second-level users, can be performed while the vehicle is in motion.

[0116] Specifically, while the vehicle is in motion, the status of the occupants and the car key remains stable, resulting in consistent occupant registration information. An empty vehicle typically only occurs after the vehicle has stopped. When the vehicle is stopped, complex situations arise where people enter and exit, such as friends retrieving items for the owner, potentially corrupting the occupant registration information during these processes. For example, if someone enters or exits the driver's seat and is not the owner, the driver's seat registration information becomes chaotic, leading to confusion for all occupants and potentially resulting in the owner being locked out of the vehicle. Therefore, it is crucial to prevent arbitrary updates to the registered primary and secondary users of the vehicle while it is stationary.

[0117] In this embodiment, registering the current vehicle's first-level user and second-level user based on the identity of the occupants and their corresponding seat information also includes:

[0118] If step 4 is performed, then the registration records of the current vehicle's second-level user, or the current vehicle's first-level user and the current vehicle's second-level user, will be deleted.

[0119] Specifically, when both the car key and the person have left the vehicle, and there is no prerequisite that the vehicle can only be unlocked by "facial recognition," it is unnecessary to retain the registration of the vehicle's second-level user.

[0120] The car owner has the highest level of access, and reserving a facial recognition unlocking option for them does not pose a risk of theft. Maintaining this primary user status also allows for handling more unexpected scenarios. First, the car owner is unlikely to steal from themselves. Second, if someone tries to steal their belongings or car keys, the owner can quickly throw the keys and items into the car and close the door automatically. At this point, only the owner can unlock the door with facial recognition; there are no other methods. The owner can then immediately move away from the danger zone. In this state, the vehicle essentially functions as a facial recognition-enabled safe, thus expanding the owner's ability to proactively respond to theft.

[0121] In this embodiment, controlling the automatic locking of the vehicle doors also includes: synchronously starting the monitoring of the vehicle status;

[0122] Register initial vehicle status information;

[0123] Initial vehicle status information includes vehicle location and engine operating status;

[0124] If the deviation between the current vehicle status and the initial vehicle status exceeds a preset threshold, preset anti-theft measures will be taken.

[0125] Pre-set anti-theft measures include controlling the vehicle to enter an abnormal driving state and sending a vehicle theft warning message.

[0126] Specifically, with advancements in theft techniques, even though vehicles are secured with locks to prevent thieves from entering, they are still at risk of being stolen. For example, thieves can forcibly pry open doors, windows, sunroofs, etc., and start the vehicle using a key left inside. Alternatively, thieves can tow the vehicle away. Therefore, along with active anti-theft systems that lock the doors, they also activate functions that monitor the vehicle's location and engine status. If the engine is detected to be running or the vehicle has been moved, corresponding anti-theft measures can be taken.

[0127] Anti-theft measures are implemented based on the specific scenario. For example, if the engine is detected to be running, the vehicle is controlled into an abnormal driving state. This could be achieved by remotely controlling or automatically timing the draining of fuel from the tank, disconnecting the spark plugs, or periodically applying the brakes until they lock, thus limiting the vehicle's movement. Anomalies in GPS location information can also indicate that the vehicle has been loaded onto another truck. By sending alerts and transmitting the vehicle's current GPS location information, this data is uploaded to the cloud and distributed to the police system, providing officers with immediate leads for recovering stolen goods. This significantly increases the cost of theft and thus deters the possibility of vehicle theft.

[0128] Figure 2 This is a structural diagram of a vehicle active anti-theft device provided in one or more embodiments of the present invention.

[0129] like Figure 2 As shown, the vehicle active anti-theft device includes: a detection module, an automatic locking module, a first unlocking module, and a second unlocking module;

[0130] The detection module is used to detect whether there are people inside the vehicle and whether the car keys have been left inside the vehicle.

[0131] The automatic door locking module is used to automatically lock the doors if no one is detected inside the vehicle.

[0132] The first unlocking module is used to unlock the car based on the occupant information if the car key is detected as being left inside the car during automatic locking.

[0133] The second unlocking module is used to unlock the car if the car key is not left inside the car when the automatic locking occurs, based on the car key information.

[0134] It is worth noting that although this system only discloses the detection module, automatic locking module, first unlocking module, and second unlocking module, it does not mean that this device is limited to the above-mentioned basic functional modules. On the contrary, what this invention intends to express is that, based on the above-mentioned basic functional modules, those skilled in the art can add one or more functional modules in combination with existing technology to form an infinite number of embodiments or technical solutions. That is to say, this system is open rather than closed. It should not be assumed that the scope of protection of the claims of this invention is limited to the above-disclosed basic functional modules just because this embodiment only discloses a few basic functional modules.

[0135] This application also discloses a vehicle lock, which includes an active anti-theft device for the vehicle.

[0136] The steps for a car lock to implement active anti-theft methods for vehicles.

[0137] Specifically, passengers can request unlocking information via facial recognition or voice commands. Car key unlocking requests can be processed by comparing the radio frequency signals transmitted by the car key.

[0138] Figure 3 This is a schematic diagram of a vehicle active anti-theft process according to a specific embodiment of the present invention.

[0139] like Figure 3 As shown, when the car owner closes the driver's door, the system checks the engine status. If the engine is locked, the in-vehicle camera is activated to check for any other occupants. If no one is present, the system performs the following actions: checks the door lock status; if the doors are unlocked, the onboard computing system issues a door locking command to automatically lock the vehicle; if there is a physical obstacle preventing locking, an alarm is triggered, alerting the owner to check and lock the vehicle; and the system checks the windows; if any window is not closed, the onboard computing system instructs the vehicle control module to close it. These measures ensure the vehicle is securely locked after use.

[0140] If the car keys are left in the car when no one is inside, the exterior camera will remain on, waiting for facial recognition to unlock the vehicle. If the car keys are left in the car when no one is inside, the exterior camera will turn off.

[0141] If a user unlocks the vehicle and closes the driver's side door, the in-vehicle camera will activate to identify the person in the driver's seat. Strangers can request authorization from the vehicle owner, and once authorized, they can use the vehicle normally. In the event of authentication failure, anti-theft and anti-robbery measures will be activated, including recording and taking photos, compressing them, and uploading them to the cloud to prevent deletion.

[0142] For unauthorized individuals entering the vehicle, such as those who pry open the door, video and photos are recorded when the door is opened. For the driver, image recognition is used; for strangers, the owner's authorization is requested, and after authorization, the vehicle can be used normally. In cases of unauthorized entry, anti-theft and anti-robbery measures are activated, including recording and taking photos, compressing them, and uploading them to the cloud to prevent deletion. In cases of forced starting of the vehicle, the starting location is uploaded to the cloud to create a vehicle trajectory, which can be viewed by the user through the app. The fuel unloading function is also activated to force unauthorized individuals to abandon the vehicle.

[0143] In the event of a vehicle robbery, since the vehicle is still running, image-based identity authentication is initiated when the doors are closed. If authentication fails, or if the user actively initiates a robbery alarm via a mobile app, anti-theft measures are activated, including notifying the police and insurance company, recording video and taking photos, compressing the footage, and uploading it to the cloud to prevent deletion. The vehicle's location is also uploaded to the cloud to create a vehicle trajectory, which the user can view using the app. Additionally, an oil unloading function is activated to force the perpetrators to abandon the vehicle.
