Description

Technical Field

[0001] This invention relates to the field of vehicle control, and more specifically, to a device control method and system for vehicle protection. Background Technology

[0002] In practical applications, as the number of vehicles increases, the importance attached to vehicle safety also increases.

[0003] If aggressive behavior can be prevented before a vehicle is scratched, the vehicle can be protected and social harmony can be maintained. Currently, there are two main ways to protect vehicles while they are parked: one is to install vehicle covers, but installing vehicle covers increases costs and the process of using them is also cumbersome.

[0004] Another approach uses a vehicle sentry mode to alert the vehicle to approaching objects. However, this mode only handles collisions and doesn't address scratches, making it ineffective in protecting the vehicle when scratched and resulting in a poor user experience. Preventing aggressive behavior before scratches occur would protect vehicles and maintain social harmony. Therefore, it's necessary to develop a device control method for vehicle protection. Summary of the Invention

[0005] In view of this, the present invention provides a device control method and system for vehicle protection, in order to solve the problem of the urgent need to protect vehicles before they are scratched.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A device control method for vehicle protection includes:

[0008] If a specified attack behavior is determined to exist in the area surrounding the target vehicle, an alarm interaction strategy is obtained. The alarm interaction strategy includes at least one sub-strategy with a priority identifier, and the sub-strategy is matched with the characteristic information of the attacker corresponding to the specified attack behavior. The sub-strategy includes at least one target device identifier and the target interaction operation to be performed by the target device corresponding to the target device identifier. The target interaction operation is used to prompt the attacker so that the attacker stops the specified attack behavior.

[0009] The sub-policies are executed sequentially according to their corresponding priority identifiers to control the target device to perform the target interaction operation until the attacker stops the specified attack behavior or the target device completes the target interaction operation.

[0010] Optionally, before determining that a specified attack behavior exists in the target area surrounding the vehicle, the method further includes:

[0011] Obtain vehicle status information, and if the vehicle status information meets the preset attack protection trigger conditions, execute the alarm interaction strategy when it is determined that a specified attack behavior exists in the target area around the vehicle.

[0012] Optionally, it is determined that a specified attack behavior exists in the area surrounding the target vehicle, including:

[0013] Collect image data of the area surrounding the target vehicle;

[0014] An image recognition operation is performed on the image data to obtain the image recognition result; the image recognition result includes the attacker type, the distance between the attacker and the vehicle, and the attacker's behavioral intent;

[0015] If the attacker type is a specified type, the distance is less than a preset distance threshold, and the behavioral intent is a preset attack intent, then a specified attack behavior is determined to exist in the target area around the vehicle.

[0016] Optionally, the sub-policies are executed sequentially according to their corresponding priority identifiers to control the target device to perform target interactive operations, including:

[0017] Obtain at least one sub-strategy with a priority identifier that corresponds to the image recognition result in the alarm interaction strategy;

[0018] Based on the sub-policy with priority marked as first priority, the voice interaction device is controlled to perform intelligent voice interaction operations with the attacker.

[0019] Optionally, executing the sub-policies sequentially according to their corresponding priority identifiers to control the target device to perform target interactive operations further includes:

[0020] If the specified attack behavior does not stop after executing the first priority sub-policy, then if the area around the target is within the specified range of the vehicle, based on the sub-policy corresponding to the specified range and marked as the second priority, the target device corresponding to the specified range is controlled to perform the target interaction operation; wherein the second priority corresponding to the specified range is lower than the first priority.

[0021] Optionally, executing the sub-policies sequentially according to their corresponding priority identifiers to control the target device to perform target interactive operations further includes:

[0022] If the specified attack behavior does not stop after executing the sub-policy corresponding to the second priority of the specified range, then based on the sub-policy with the priority identifier as the third priority, the communication connection device is controlled to establish a communication connection with the target user terminal of the vehicle, so as to realize the voice call between the target user terminal and the attacker; the third priority is lower than the second priority.

[0023] Optionally, if it is determined that a specified attack behavior exists in the target area surrounding the vehicle, the method further includes:

[0024] Collect and store audio and video data of the area surrounding the target.

[0025] Optionally, before determining that a specified attack behavior exists in the target area surrounding the vehicle, the method further includes:

[0026] Determine whether the function switch can be turned on; wherein, if the vehicle state meets the preset state, the function switch is allowed to be turned on by the user.

[0027] If enabled, the alarm interaction strategy will be executed if a specified attack behavior is determined to exist in the target area around the vehicle.

[0028] A device control system for vehicle protection includes a controller for performing the above-described device control method for vehicle protection.

[0029] Optionally, it also includes a target device, which is used to perform a target interactive operation according to the control instructions of the controller.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] This invention provides a device control method and system for vehicle protection. When a specified attack behavior exists in the area surrounding the vehicle, i.e., when an attacker, such as a child, attacks the vehicle, the sub-policies in the alarm interaction strategy are executed sequentially according to the corresponding priority identifier. This controls the target device to perform target interactive operations, attracting the attacker's attention and prompting and persuading the attacker to stop attacking the vehicle. This invention can, to a certain extent, prevent attackers from scratching the vehicle, improving the user experience. Furthermore, it eliminates the need for additional components such as vehicle covers, thus not increasing costs and avoiding the cumbersome nature of using such components. Moreover, the sub-policies in this invention match the attacker's characteristic information corresponding to the specified attack behavior, resulting in a higher degree of matching between the alarm interaction strategy and the vehicle attack scenario, making it more acceptable to attackers and more effectively protecting the vehicle.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0039] This invention provides a method for responding to attacks on vehicles, specifically when an attacker (e.g., a child) is present in the vicinity of a target area. The method executes sub-strategies within an alarm interaction strategy according to priority indicators, controlling the target device to perform interactive operations to attract the attacker's attention and prompting them to cease their attacks. This approach effectively prevents attackers from scratching vehicles, improves user experience, and eliminates the need for additional components such as vehicle covers, thus avoiding increased costs and the inconvenience of such necessities. Furthermore, the sub-strategies in this invention are matched with the attacker's characteristic information corresponding to the specified attack behavior, resulting in a higher degree of relevance between the alarm interaction strategy and the vehicle attack scenario. This makes the strategy more acceptable to attackers and more effectively protects the vehicle.

[0040] It should be noted that the attacker in this embodiment includes, but is not limited to, children, adults, and animals. Any creature with aggressive behavior can be referred to as the attacker in this embodiment.

[0041] The device control method for vehicle protection provided by this invention can be implemented by a newly added controller on the vehicle, such as a warning controller, specifically through a warning control module within the warning controller. Alternatively, an existing controller on the vehicle, such as an intelligent driving controller, can also be used to execute the device control method described in this embodiment.

[0042] Based on the above, refer to Figure 1 A device control method for vehicle protection according to the present invention may include the following steps:

[0043] S11. If a specified attack behavior is determined to exist in the area surrounding the target vehicle, obtain the alarm interaction strategy.

[0044] In practical applications, step S11 will only be executed when the preset attack protection trigger conditions are met. The preset attack protection trigger conditions can be pre-set, and these conditions include certain vehicle status judgment rules. Only when these judgment rules are met is it considered that the alarm interaction strategy can be executed.

[0045] Before step S11, it is necessary to first obtain vehicle status information to determine whether the vehicle status information meets the preset attack protection trigger conditions.

[0046] Vehicle status information refers to the operational data of the vehicle's current state, which may include, but is not limited to, the vehicle's internal power mode, vehicle mode, gear position, battery charge level, and door lock status signals. Vehicle status information can be obtained from the corresponding controller through the vehicle information acquisition module; for example, battery charge level is obtained from the BMS (Battery Management System).

[0047] Among the preset attack protection trigger conditions, when the vehicle power mode is OFF, the vehicle mode is Normal, the power battery charge is greater than or equal to 20%, the door lock status is Locked, and the function switch (the aforementioned soft switch or hard switch) has been turned on, it indicates that the function in this embodiment is in an active state, and step S11 can be executed.

[0048] In this embodiment, the judgment rules set in the preset attack protection trigger bar are to ensure that if an attack occurs when the vehicle is parked, the user gets out of the car and the car is locked, the alarm interaction strategy is allowed to be executed.

[0049] In addition, the present invention limits the power battery charge to greater than or equal to 20% in order to ensure that there is enough power to execute the alarm interaction strategy.

[0050] Before executing step S11, a target area around the vehicle can be preset. This area is a set area around the vehicle, such as an area in front of, behind, to the left or right of the vehicle.

[0051] Generally, when a vehicle is attacked, an attacker will be present around the vehicle and will engage in actions that could damage it. Therefore, it is necessary to detect whether specific attack behaviors exist in the target area around the vehicle. When the attacker is a child or an adult, the specific attack behaviors could include actions that could damage vehicle parts, such as scratching the vehicle with tools, throwing stones at the vehicle, hitting the vehicle with hands, or kicking the vehicle.

[0052] When a specified attack behavior is detected, an alarm interaction policy can be retrieved. The alarm interaction policy can be pre-stored in the controller's memory.

[0053] Different alarm interaction strategies can be set based on the attacker's characteristics. For example, alarm interaction strategies can be set based on the attacker's age, gender, species, or other characteristics.

[0054] For example, if the attacker is a child, use gentle language that the child can understand, and use soft lighting when turning on lights to avoid harming their eyes. If the attacker is an adult, use stern language, and if necessary, use a threatening tone. If the attacker is an animal, use sounds that the animal fears to scare it away.

[0055] In addition, the alarm interaction policy may also include at least one sub-policy with a priority identifier, and the sub-policy is matched with the attacker's characteristic information corresponding to the specified attack behavior. For details on matching the sub-policy with the attacker's characteristic information corresponding to the specified attack behavior, please refer to the corresponding explanation above.

[0056] In this embodiment, the sub-strategies have priority identifiers, which can be first priority, second priority, third priority, etc. The priority levels of first priority, second priority, and third priority decrease sequentially. The content of the sub-strategies executed for different priorities is different, and the sub-strategies arranged in priority order belong to a progressive strategy. That is, when executing the alarm interaction strategy, fewer vehicle actions are executed first. If the specified attack behavior cannot be prevented, more vehicle actions can be executed. If the specified attack behavior still cannot be prevented, the vehicle owner can be notified so that the owner can prevent the specified attack behavior by communicating with the vehicle and outputting voice. If the specified attack behavior still cannot be prevented, the operation to prevent the specified attack behavior is stopped, and the collected audio and video data of the surrounding area of ​​the target is stored in a timely manner to provide corresponding evidence in case of subsequent disputes.

[0057] It should be noted that if executing a certain sub-policy prevents the specified attack behavior, then subsequent sub-policies will not be executed.

[0058] In this embodiment, the sub-policy includes at least one target device identifier and the target interaction operation that the target device corresponding to the target device identifier needs to perform. The target interaction operation is used to prompt the attacker and influence the attacker's specified attack behavior, so as to make the attacker stop the specified attack behavior.

[0059] Let's illustrate the specific content of the sub-strategy using a child as an example of an attacker. Generally, due to children's strong curiosity, actions such as using voice commands, lights, turning on the washers, windshield wipers, side mirrors, or welcome lights can be used to attract the child's attention and stop them from attacking the vehicle. The target device identifiers that can be included in the sub-strategy can be smart voice device identifiers, hazard light identifiers, windshield wiper identifiers, washers identifiers, welcome light identifiers, side mirror identifiers, communication connection device identifiers, etc.

[0060] The target interactive operation to be performed by the target device corresponding to the target device identifier can be intelligent voice interaction between the voice interaction device and the attacker, the washer and the wiper working together to clean the glass, turning on the hazard lights, adjusting the unfolding angle of the exterior rearview mirror, turning on the welcome lights, or suggesting communication connection with the vehicle owner's terminal, etc.

[0061] In practical applications, the target device identifiers and target interaction operations described above can be categorized to obtain at least one sub-policy. For example, three sub-policies can be obtained. The priority of the three sub-policies decreases sequentially.

[0062] For example, a first-priority sub-strategy could be: controlling the voice interaction device to perform intelligent voice interaction with the attacker. A second-priority sub-strategy could be: the voice interaction device performing intelligent voice interaction with the attacker, the washer and wipers working together to clean the windshield, or activating at least one of the following: the hazard lights being turned on. A third-priority sub-strategy could be: controlling the communication connection device to establish a communication connection with the target user terminal in the vehicle.

[0063] It should be noted that the embodiments of the present invention can also set different sub-strategies based on the different positions of vehicles in the surrounding area of ​​the target.

[0064] For example, when a child is in front of or behind the vehicle, the washer fluid, windshield wipers, and hazard lights can be used to attract the child's attention. When a child is on the left or right side of the vehicle, the side mirrors and welcome lights can be used to attract the child's attention. Furthermore, the sub-strategies for the second priority can be further subdivided. For instance, a specified range can be divided into sub-strategies within a specified front-to-back range and sub-strategies within a specified left-to-right range.

[0065] The second priority sub-policy for specifying the preceding and following ranges can be at least one of the following: performing intelligent voice interaction between the voice interaction device and the attacker, the washer and the wiper working together to clean the glass, or turning on the hazard lights.

[0066] The sub-policy specifying the second priority range for the left and right sides can be at least one of the following: performing intelligent voice interaction between the voice interaction device and the attacker, adjusting the unfolding angle of the exterior rearview mirror, or turning on the welcome lights.

[0067] In this embodiment, the voice interaction device can be a device capable of intelligent voice interaction, including an interaction controller, an external microphone, and an external microphone. The interaction controller can be an existing controller on the vehicle, such as an intelligent driving controller, used to determine the content of the conversation with the attacker. The external microphone is used to output this content, and the external microphone is used to collect external sounds, specifically the attacker's voice response. In this embodiment, the voice interaction device can also be a component with communication capabilities, such as an infotainment module, which can communicate wirelessly or via telephone.

[0068] Washers, wipers, hazard lights, exterior rearview mirrors, and welcome lights can be controlled by the vehicle body control module. The vehicle body control module receives control commands from the controller in this embodiment to control the exterior rearview mirrors to fully unfold, fully fold, or fold and unfold at an angle, control the vehicle's hazard lights to turn on or off, control the welcome lights to turn on or off, and control the operation of the front and rear wipers and washers.

[0069] When the washer is in operation, the front and rear washer motors receive control commands from the vehicle body control module to spray washer fluid.

[0070] When controlling the windshield wipers, the front / rear wiper motors receive control commands from the vehicle body control module to perform operations such as turning the wipers on and off and adjusting the wiper speed.

[0071] When controlling the operation of the exterior rearview mirror, the exterior rearview mirror control motor receives commands from the vehicle body control module and folds or unfolds the exterior rearview mirror at a specified angle.

[0072] When controlling the hazard lights, the lighting unit receives commands from the vehicle control module to operate and control the hazard lights. In addition, the lighting unit can also control the headlights.

[0073] When controlling the welcome lights, which are mounted on the exterior rearview mirrors, the welcome lights are turned on or off by receiving commands from the vehicle control module. The welcome lights can be set with various light signals that children like.

[0074] The controller controls the exterior rearview mirror, lights, welcome lights, washers, wipers, and microphone according to the default alarm interaction strategy or the alarm interaction strategy programmed by the user, so as to coax or dissuade attackers, such as children.

[0075] It should be noted that the specific content of the sub-strategies in this embodiment can be set according to the actual scenario. For example, operations such as adding horn sounds can also be added. In addition, the color of the welcome lights and the lighting time of the welcome lights can also be adjusted. Specifically, it can be based on user configuration or system default operations.

[0076] S12. Execute sub-policies sequentially according to their corresponding priority identifiers to control the target device to perform the target interactive operation until the attacker stops the specified attack behavior or the target device completes the target interactive operation.

[0077] Specifically, sub-policies are executed sequentially according to their priority. When executing a sub-policy, the execution time can be limited, such as one minute or two minutes. If the specified attack behavior cannot be prevented when the execution time is up, i.e., the attacker's behavior of damaging the vehicle cannot be prevented, the next priority sub-policy will be executed until all sub-policies have been executed.

[0078] If the attacker's actions to damage the vehicle can be prevented before the execution time expires, the execution of this sub-policy will be stopped, and the existence of the specified attack behavior in the target area around the vehicle will be determined in real time. If it exists, the alarm interaction policy will be re-executed.

[0079] When a specified attack behavior exists in the area surrounding the vehicle, i.e. when an attacker, such as a child, attacks the vehicle, the sub-policies in the alarm interaction strategy are executed sequentially according to the corresponding priority identifier. This controls the target device to perform target interaction operations, attracting the attacker's attention and prompting and persuading the attacker to stop attacking the vehicle.

[0080] In addition, in this embodiment, corresponding sub-policies can be configured for different types of attackers, such as children and adults, making the sub-policies more reliable and easier to persuade attackers to stop attacking vehicles.

[0081] In another implementation of the present invention, to avoid subsequent disputes, audio and video data of the area surrounding the target can be collected and stored as soon as a specified attack behavior is determined to exist within the target area of ​​the vehicle. For example, video data can be collected using the aforementioned camera, and audio data can be collected using an external microphone. After data fusion, audio and video data are obtained to save the attacker's attack behavior data on the vehicle in real time.

[0082] In another embodiment of the present invention, reference is made to Figure 2 Step S20 can be performed before performing step S11 above, as follows:

[0083] S20. Determine whether the function switch can be turned on. If yes, proceed to step S11; otherwise, repeatedly determine whether the function switch can be turned on.

[0084] In this embodiment, the function switch is allowed to be activated by the user when the vehicle status meets a preset condition. In practical applications, before any attempt to instigate a vehicle attack, the function switch corresponding to the device control method in this embodiment must be in the 'on' state. This function switch can be a soft switch or a hard switch, primarily enabling and disabling the function. In this embodiment, when the function is enabled, the controller performs logical judgment based on the alarm interaction logic strategy and outputs control commands to control the vehicle body control module and the external microphone according to the user-set alarm interaction strategy or the system's default alarm interaction strategy, thereby protecting the vehicle and preventing scratches.

[0085] If the function switch is a hard switch, it can be integrated into the body controller. Users can enable or disable the function by adjusting the switch's on / off position (such as on and off). The body controller is connected to the persuasion controller or intelligent driving controller in this embodiment, so that when the user toggles the hard switch, the function enable or disable command is promptly transmitted to the persuasion controller or intelligent driving controller in this embodiment.

[0086] If it is a soft switch, the soft switch can be set on the infotainment module, such as the central control screen. Users can turn the switch on and off via touch screen. The central control screen will transmit the user's on or off command to the control controller or intelligent driving controller in this embodiment.

[0087] Specifically, when the vehicle status meets preset conditions, such as the vehicle power mode being "On," the vehicle mode being "Normal," and the power battery charge being ≥20%, the function switch can be activated by the user, enabling vehicle protection. After the user activates this function via a software or hardware switch, the user can customize the alarm interaction strategy; otherwise, the controller will use the default alarm interaction strategy.

[0088] When users personalize alarm interaction strategies, a strategy configuration interface can be displayed on the infotainment module, such as the central control screen. Users can select the target devices to be controlled on this interface, such as one or more devices including washer fluid, wipers, hazard lights, welcome lights, and exterior mirrors. Furthermore, users can configure the target interactive operations for these devices, such as the unfolding angle of the exterior mirrors, the color of the welcome lights, and the washing time of the washer fluid. After configuring, users can click the save button to complete the personalized configuration.

[0089] It should be noted that, Figure 2 For the specific implementation process of steps S21 and S22, please refer to the corresponding descriptions in the above embodiments.

[0090] In this embodiment, users can turn the function switch on or off according to their own needs to protect the vehicle as required. Furthermore, when protecting the vehicle, users can personalize the alarm interaction strategy to meet their individual needs.

[0091] Based on the above embodiments, determining whether a specified attack behavior exists can be done by the controller or by other devices, such as the vehicle controller, and the determination result is transmitted to the controller in this invention. However, regardless of the method, the determination process is the same. The detailed implementation process will now be described using the controller's determination of the existence of a specified attack behavior as an example.

[0092] Specifically, refer to Figure 3 Determining that a specific attack is occurring within the target area surrounding the vehicle can include:

[0093] S31. Collect image data of the area surrounding the target vehicle.

[0094] Specifically, cameras can be used to collect image data of the area surrounding the vehicle. In practical applications, at least four cameras need to be installed on the vehicle's exterior (front, rear, left, and right). These cameras can be added later or used with intelligent driving functions. The number of cameras is not limited and can be determined based on the actual configuration, as long as the monitored images cover the entire perimeter of the vehicle. The type of camera is also not restricted, as long as it can collect image data, such as a surround-view camera.

[0095] When the above functions are activated, the camera can be turned on and image data can be collected to ensure that effective persuasion can be carried out in a timely manner if an attacker attacks the vehicle.

[0096] S32. Perform image recognition operation on the image data to obtain the image recognition result of the image data.

[0097] The image recognition results include the attacker type, the distance between the attacker and the vehicle, and the attacker's behavioral intent.

[0098] This step can be implemented through the data processing module in the controller. During image recognition, neural network algorithms and / or target recognition algorithms can be used. For example, two neural network models can be constructed. One model identifies whether a specific type of attacker is present (specifically, whether a living being is present, such as a child, adult, or animal), and, if so, the distance between the attacker and the vehicle. The other neural network model identifies the attacker's behavioral intent, which could be an intention to damage the vehicle, such as scratching, kicking, or striking.

[0099] Furthermore, target recognition algorithms can be used to identify whether a specific type of attacker exists in the image data, and if so, the distance between the attacker and the vehicle. Then, a neural network model is used to identify the attacker's behavioral intent.

[0100] In addition, a single neural network model can be built to directly identify whether a specified type of attacker exists, and when such an attacker exists, the distance between the attacker and the vehicle, as well as the attacker's behavioral intent.

[0101] The various neural network models mentioned above use different labeled training samples, resulting in different recognized content.

[0102] S33. When the attacker type is a specified type, the distance is less than a preset distance threshold, and the behavioral intent is a preset attack intent, it is determined that a specified attack behavior exists in the target area around the vehicle.

[0103] Specifically, when aggressive behavior occurs, the attacker type will be set to a specified type, such as a child, adult, or animal. Setting the attacker type to a specified type can prevent non-living things such as balloons or debris from getting close to vehicles, which cannot be persuaded.

[0104] When an attack occurs, the attacker is usually close to the vehicle. Therefore, in this embodiment, the distance between the attacker and the vehicle is limited to less than a preset distance threshold. The preset distance threshold can be set in advance, such as 1 meter or 2 meters.

[0105] In addition, the behavioral intent must be set as a preset aggressive intent. The preset aggressive intent can be the intent to damage the vehicle, such as a child scratching the vehicle with a tool or kicking the vehicle.

[0106] When the attacker type is specified, the distance is less than a preset distance threshold, and the behavioral intent is a preset attack intent, it is determined that there is a specified attack behavior in the target area around the vehicle, that is, an attacker wants to damage the vehicle. At this time, vehicle control is required to persuade the attacker to stop damaging the vehicle.

[0107] It should be noted that if an attacker of a specified type is detected within a preset distance threshold, but the attacker does not yet have the intention to attack the vehicle, the behavior intent detection will continue. Once a preset attack intent is detected, vehicle control can be initiated.

[0108] In this embodiment, the existence of a specified attack behavior is determined by combining the attacker type, the distance between the attacker and the vehicle, and the attacker's behavioral intent. This allows for a multi-faceted assessment of whether an attacker is damaging the vehicle, resulting in a more accurate assessment and preventing misoperation.

[0109] In another implementation of the present invention, the specific implementation process of step S12 based on the recognition result of S23 is given. First, at least one sub-strategy with priority identifier corresponding to the image recognition result in the alarm interaction strategy is obtained.

[0110] Taking a child attacker as an example, three priority sub-policies are set, and the specific explanations of the sub-policies are as follows. If the attacker is of other types, corresponding sub-policies can be set.

[0111] Based on the sub-policy with priority marked as first priority, control the voice interaction device to perform intelligent voice interaction operations with the attacker.

[0112] If the specified attack behavior does not stop after executing the first priority sub-policy, then if the area around the target is within the specified range of the vehicle, based on the sub-policy corresponding to the specified range and marked as the second priority, the target device corresponding to the specified range is controlled to perform the target interaction operation; wherein the second priority corresponding to the specified range is lower than the first priority.

[0113] If the specified attack behavior does not stop after executing the sub-policy corresponding to the second priority of the specified range, then based on the sub-policy with the priority identifier as the third priority, the communication connection device is controlled to establish a communication connection with the target user terminal of the vehicle, so as to realize the voice call between the target user terminal and the attacker; the third priority is lower than the second priority.

[0114] The second priority is further divided into two cases depending on the specified range:

[0115] If the specified attack behavior does not stop after executing the first priority sub-policy, then if the area around the target is within the specified front and rear range of the vehicle, based on the sub-policy corresponding to the specified front and rear range and marked as the second priority, the target device corresponding to the specified front and rear range will be controlled to perform the target interaction operation; wherein, the second priority corresponding to the specified front and rear range is lower than the first priority; the target interaction operation performed by the target device corresponding to the specified front and rear range includes at least one of the following: intelligent voice interaction operation between the voice interaction device and the attacker, the washer and the wiper working together to clean the glass, and turning on the hazard lights.

[0116] Alternatively, if the specified attack behavior does not stop after executing the first priority sub-policy, then if the area around the target is within the specified left and right range of the vehicle, execute the sub-policy corresponding to the specified left and right range and marked with the second priority, to control the target device corresponding to the specified left and right range to perform the target interactive operation; wherein, the second priority corresponding to the specified left and right range is lower than the first priority; the target interactive operation performed by the target device corresponding to the specified left and right range includes at least one of the following: the voice interaction device performing intelligent voice interaction operation with the attacker, adjusting the unfolding angle of the exterior rearview mirror, and turning on the welcome lights.

[0117] To enable those skilled in the art to better understand the present invention, examples are provided below.

[0118] When the controller detects a child in front of or behind the vehicle and attempting to damage it, it will proactively activate the voice interaction device to engage in dialogue with the child, attracting their attention and coaxing them. If voice persuasion is ineffective, it will activate the windshield washer fluid and wipers, and simultaneously turn on the hazard lights. The voice interaction device will also respond to the vehicle's actions with a scenario dialogue, such as, "You can't touch me, I'll cry if you touch me," simulating a crying sound. It will then begin to explain to the child that "damaging other people's property is wrong." If the child responds to the voice prompt, the voice interaction device will engage in intelligent dialogue based on the child's response, shifting the context to a persuasive scenario. For example, if the child replies, "Then what else can you do?", the voice interaction device should reply, "I can take pictures. If you bully me again, I'll send the pictures to my owner, and my owner will find you!" If the child continues to damage the vehicle, the vehicle will proactively call the owner to persuade the child to calm down.

[0119] The above embodiments describe the situation where the child is in front of or behind the vehicle. If the child is on the left or right side of the vehicle, the second priority sub-policy is different. If the specified attack behavior does not stop after executing the second priority sub-policy corresponding to the specified left or right range, the sub-policy marked as the third priority is executed.

[0120] For example, if the controller detects a child on the left or right side of the vehicle and intends to damage it, it will proactively activate the voice interaction device to engage in dialogue with the child, attracting their attention and coaxing them. If voice persuasion is ineffective, the vehicle will unfold the exterior rearview mirrors and turn on the welcome lights. Simultaneously, the intelligent voice will coordinate with the vehicle's control actions to engage in a scenario-based dialogue, such as, "Don't hit me anymore. How about I perform a magic trick for you? Can you find the picture I drew on the ground?" The image projected onto the ground by the welcome lights will attract the child's attention. During the interaction, the unfolding angle of the exterior rearview mirrors will be continuously adjusted to keep the image on the ground moving, constantly attracting the child's attention and discouraging them from damaging the vehicle. If the child still intends to damage the vehicle, the vehicle will proactively call the vehicle owner to coax the child.

[0121] In this embodiment, if the user does not personalize the alarm interaction strategy, the system will use the default strategy. For example, the controller receives the behavior data of the child outside the vehicle provided by the data processing module, controls the external microphone and microphone to conduct intelligent language interaction with the child, and controls the external rearview mirror, lights, welcome lights, washers, and wipers through the vehicle control module to cooperate with the voice to coax or attract the child's attention. When coaxing is ineffective, the infotainment module can call the vehicle owner's phone to establish a real-time telephone communication between the vehicle owner and the child outside the vehicle, allowing the vehicle owner to coax the child. During this process, the audio and video information outside the vehicle needs to be stored locally.

[0122] The solution proposed in this invention enables effective and proactive persuasion of children when they attempt to damage vehicles, using voice and vehicle gestures. This not only avoids property damage caused by vehicle damage and psychological trauma to children, but also provides a loving way to comfort children, avoiding the frightening behavior caused by ordinary alarm methods.

[0123] It should be noted that if the attacker is an adult, since adults are mentally mature, their behavior can be stopped directly with a critical tone. Alternatively, the external microphone or mouthpiece can be controlled to conduct intelligent language interaction with the adult. If this fails to dissuade them, the vehicle owner can be directly dialed to establish real-time telephone communication between the vehicle owner and the adult outside the vehicle, allowing the vehicle owner to dissuade the adult.

[0124] Based on the above, another embodiment of the present invention provides a device control system for vehicle protection, including a controller for performing the above-described device control method for vehicle protection.

[0125] Furthermore, it also includes a target device, which is used to perform target interactive operations according to the control instructions of the controller.

[0126] The target devices can be the aforementioned exterior rearview mirrors (operated by controlling the exterior rearview mirror motors), lighting systems (including hazard lights and headlights), welcome lights, washer systems (operated by controlling the front / rear washer motors), windshield wipers (operated by controlling the front / rear wiper motors), and voice interaction devices (including exterior microphones and microphones), etc. For specific connection structures, please refer to... Figure 4 For specific working procedures, please refer to the corresponding descriptions in the above embodiments.

[0127] The entire workflow of the controller can be referenced. Figure 5 Steps S41-S47. Specifically, the controller collects internal vehicle information data, such as the aforementioned internal power mode, vehicle mode, gear position, battery charge, and door lock status signals. It can configure function switch states or program personalized alarm interactions according to user settings, then determine if the function switch is activated. If activated, it can collect external image data, identify external attack behaviors, determine and execute control strategies. Refer to the corresponding sections above for details.

[0128] In this embodiment, when a specified attack behavior exists within the target area surrounding the vehicle, i.e., when an attacker attacks the vehicle, the sub-policies in the alarm interaction strategy are executed sequentially according to the corresponding priority identifier. These sub-policies control the target device to perform target interactive operations, attracting the attacker's attention and prompting and persuading the attacker to cease attacking the vehicle. This invention can, to a certain extent, prevent attackers from scratching the vehicle, improving the user experience. Furthermore, since the sub-policies in this invention match the attacker's characteristic information corresponding to the specified attack behavior, the alarm interaction strategy has a higher degree of matching with the vehicle attack scenario, making it more acceptable to attackers and more effectively protecting the vehicle.

[0129] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
