Description

Technical Field

[0001] This invention relates to the field of automotive safety technology, and more particularly to a vehicle door opening warning method, device, storage medium, and vehicle. Background Technology

[0002] With the development of technology, more and more vehicles are equipped with door opening warning functions. Currently, most common door opening warning systems on the market remind drivers and passengers to pay attention to door opening safety through methods such as prompts on the vehicle's central control display screen, visual prompts on the instrument panel, audible prompts, and changes in the color of the door ambient lighting.

[0003] However, in situations where users are distracted by conversation (such as when the driver and passenger are settling the fare) or the vehicle is in a harsh environment (such as during thunderstorms or near a construction site), the visual and / or auditory warning signals relied upon by existing vehicle door opening warning systems are easily ignored by the driver or passenger, and the danger of opening the door still exists. Summary of the Invention

[0004] This invention provides a vehicle door opening warning method, device, storage medium, and vehicle to at least solve the problem that the warning signals issued by existing vehicle door opening warning systems are easily ignored by users, making it difficult to ensure user door opening safety. It improves the intuitiveness, safety, effectiveness, and environmental adaptability of vehicle door opening warnings, thereby helping to ensure user door opening safety and improve the user's driving experience.

[0005] In a first aspect, embodiments of the present invention provide a vehicle door opening warning method, the method comprising at least the following steps:

[0006] S1. In response to a user's attempt to get out of the vehicle after it has stopped, detect whether there is a risk of the door opening.

[0007] S2. If the aforementioned door opening hazard exists, execute the door opening warning action;

[0008] S3. In response to the user's door-pushing operation, determine whether the user's door-pushing operation meets the door-opening restriction conditions;

[0009] S4. If the user's door-pushing operation meets the door-opening restriction conditions, then at least after the door-opening restriction action is performed, the process will re-enter step S3 until the user's door-pushing operation no longer meets the door-opening restriction conditions and there is no danger of opening the door, and then proceed to step S5.

[0010] S5. Remove the door opening restriction to allow the doors to open normally.

[0011] Optionally, step S3 includes at least the following steps:

[0012] S31. In response to the user's door-opening operation, determine whether the user's door-opening operation is the first door-opening operation;

[0013] S32. If the user's door-pushing operation is the first door-opening operation, then it is determined that the door-opening restriction condition is met;

[0014] S33. If the user's door-pushing operation is not the first door-opening operation, then determine whether the interval between the user's door-pushing operation and the user's last door-pushing operation meets the first preset time condition.

[0015] S34. If the interval between the user's door-pushing operation and the user's last door-pushing operation does not meet the first preset time condition, then it is determined that the door-opening restriction condition is met.

[0016] Optionally, before step S31, the method further includes:

[0017] S35. In response to the user's door-pushing operation, determine whether the total duration of the user's door-pushing operation meets the second preset time condition.

[0018] S36. If the total duration of the user pushing the door meets the second preset time condition, proceed to step S5; otherwise, proceed to step S31.

[0019] Optionally, the user's door-pushing operation not conforming to the door-opening restriction conditions includes at least:

[0020] The user's door-opening operation is not the first door-opening operation, and the interval between the user's door-opening operation and the user's last door-opening operation meets the first preset time condition.

[0021] Optionally, after step S3, the method further includes:

[0022] S6. If the door opening restriction conditions are met, then at least after the door opening restriction action is performed, in response to the user's door closing operation, the process re-enters step S1.

[0023] Optionally, the door opening warning action includes at least one of the following: increased door resistance on the dangerous side of the door opening, image display on the dangerous side of the door opening, and alarm sound prompt;

[0024] The door opening restriction action includes at least one of the following: increased door resistance on the dangerous side of the door opening and limited door opening distance on the dangerous side of the door opening.

[0025] Secondly, embodiments of the present invention also provide a vehicle door opening warning device, comprising:

[0026] The door opening hazard detection module is used to detect whether there is a door opening hazard in response to a user's intention to get out of the vehicle after the vehicle has stopped.

[0027] The door opening warning execution module is used to execute a door opening warning action when the door opening danger detection module detects the door opening danger;

[0028] The door opening restriction determination module is used to respond to the user's door pushing operation and determine whether the user's door pushing operation meets the door opening restriction conditions;

[0029] The door opening restriction execution module is used to re-enter the door opening restriction judgment module at least after executing the door opening restriction action when the user's door pushing operation meets the door opening restriction conditions, until the user's door pushing operation no longer meets the door opening restriction conditions and there is no danger of opening the door, and then enter the door opening restriction cancellation module.

[0030] The door opening restriction cancellation module is used to cancel the door opening restriction so that the door can be opened normally.

[0031] Thirdly, embodiments of the present invention also provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements a vehicle door opening warning method as described in any of the first aspects.

[0032] Fourthly, embodiments of the present invention also provide a vehicle, comprising:

[0033] An electronic device for implementing the steps of the vehicle door opening warning method according to any one of the first aspects;

[0034] A processor that runs a program that, when the program is running, performs the steps of the vehicle door opening warning method described in any of the first aspects from data output by the electronic device.

[0035] A storage medium for storing a program that, when running, performs the steps of the vehicle door opening warning method described in any of the first aspects in response to data output from an electronic device.

[0036] This invention provides a vehicle door opening warning method, system, storage medium, and vehicle. First, in response to a user's attempt to exit the vehicle after it has stopped, the system detects whether there is a door opening hazard. Second, if a door opening hazard exists, a door opening warning action is executed. Then, in response to a user's door-pushing operation, it is determined whether the user's door-pushing operation meets the door opening restriction conditions. If the user's door-pushing operation meets the door opening restriction conditions, the system re-responds and determines whether subsequent user door-pushing operations meet the door opening restriction conditions at least after executing the door opening restriction action, until a user door-pushing operation no longer meets the door opening restriction conditions and there is no door opening hazard. Finally, after determining that the user's door-pushing operation no longer meets the door opening restriction conditions and there is no door opening hazard, the door opening restriction is lifted, allowing the vehicle door to open normally.

[0037] In view of this, in the process from detecting a door opening hazard to finally canceling the door opening restriction, this embodiment of the invention needs to execute at least one door opening warning action and determine whether at least one user door pushing operation meets the door opening restriction conditions. The door can only be opened normally if and only if the user door pushing operation no longer meets the door opening restriction conditions and there is no door opening hazard. Under other conditions, user door opening will be restricted. Obviously, through the door opening warning and door opening restriction process involved in the above process, this embodiment of the invention can provide users with multiple door opening warnings and protection measures after detecting a door opening hazard. It can solve the problem that the warning signals issued by existing vehicle door opening warning systems are easily ignored by users, making it difficult to ensure user door opening safety. It improves the intuitiveness, safety, effectiveness, and environmental adaptability of vehicle door opening warnings, which is conducive to ensuring user door opening safety and improving the user's driving experience.

[0050] It should be noted that any symbols and / or numbers present in the specification that are not marked in the accompanying drawings are not reference numerals.

[0051] This invention provides a vehicle door opening warning method. Figure 1This is a flowchart of a vehicle door opening warning method provided in an embodiment of the present invention. This embodiment is applicable to door opening hazard warning scenarios for various types of vehicles, such as gasoline-powered vehicles, pure electric vehicles, hybrid electric vehicles, plug-in hybrid electric vehicles, range-extended electric vehicles, and autonomous vehicles. The vehicle door opening warning method can be, but is not limited to, executed by the vehicle door opening warning device in this embodiment of the present invention, which can be implemented using software and / or hardware. Figure 1 As shown, the vehicle door opening warning method includes at least the following steps:

[0052] S1. In response to a user's attempt to get out of the vehicle after it has stopped, detect whether there is a risk of opening the door.

[0053] In this context, "users" can refer to vehicle drivers, passengers, etc. It is understood that, based on different real-world application scenarios, when the vehicle only carries the driver, only one door needs to be detected for potential opening hazards. If the vehicle carries other passengers besides the driver, multiple doors need to be detected for potential opening hazards. Detecting potential opening hazards can involve using any existing millisecond-wave radar, vehicle-mounted camera, or other sensors or devices to collect multiple frames of images of objects outside the vehicle to obtain their trajectory information. This trajectory information is then analyzed using a pre-trained trajectory prediction model. If the predicted trajectory of the object moves to the vicinity of the door and affects its normal opening, then a potential opening hazard is considered to exist.

[0054] In one specific implementation, when determining which door(s) pose a risk of opening, the mass or gravity data of all seats in the vehicle can be obtained first. Then, the position of the passenger or driver in the vehicle can be determined based on the mass or gravity data corresponding to each seat. Finally, based on the position of the passenger and driver, the corresponding door can be determined to be the nearest one that poses a risk of opening.

[0055] In another specific implementation, when determining which door(s) pose a danger of opening, the detection range for the door opening hazard can be appropriately adjusted by acquiring information about the surrounding environment or road conditions when the vehicle is parked. This allows for a judgment on whether opening the door poses a danger based on the surrounding environmental or road condition information. For example, when temporarily parking on urban roads, if there are vehicles or pedestrians traveling at high speeds, the detection range for the door opening hazard can be appropriately increased to prevent vehicles or pedestrians suddenly rushing out due to obstructed vision from threatening the user's safety. Similarly, when parking in parking lots or residential areas where vehicle speed limits are in place or where there are few pedestrians, the detection range for the door opening hazard can be appropriately reduced to improve the accuracy of the detection.

[0056] It is understood that this embodiment can adaptively set the detection range before detecting whether there is a door opening hazard. Different detection ranges can be selected according to the user's specific needs, thereby improving the detection accuracy of door opening hazards in different application scenarios, further ensuring user door opening safety, and helping to improve the environmental adaptability and user experience of vehicle door opening warning.

[0057] S2. If there is a risk of the door being opened, execute the door opening warning action.

[0058] When a door opening hazard is detected, the door opening warning action may optionally include at least one of the following: increased resistance of the door on the dangerous side, image display on the dangerous side, and alarm sound.

[0059] In addition, the specific ways to increase the resistance of the car door on the dangerous side of opening the door can be to control the speed and force of the door opening through a hydraulic or pneumatic system, thereby increasing the resistance when the door is opened; the specific way to display the image on the dangerous side of opening the door can be through the car's central control screen or any device with image display function; the specific way to provide the alarm sound can be through any device with voice function, such as an in-vehicle voice assistant or in-vehicle audio system.

[0060] S3. In response to the user's door pushing operation, determine whether the user's door pushing operation meets the door opening restriction conditions;

[0061] The user's door-pushing operation can refer to the action of pulling the door handle and pushing the door open. Adaptively, determining whether the user's door-pushing operation meets the door-opening restriction conditions can refer to judging the user's action of pulling the door handle and pushing the door open to determine whether the action needs to be restricted.

[0062] S4. If the user's door-pushing operation meets the door-opening restriction conditions, then at least after executing the door-opening restriction action, re-enter step S3 until the user's door-pushing operation no longer meets the door-opening restriction conditions and there is no danger of opening the door, then proceed to step S5.

[0063] The door opening restriction action can refer to taking restrictive measures on the vehicle door to prevent it from opening normally. In one specific implementation, the door opening restriction action may optionally include at least one of increased door resistance on the dangerous side of the door opening and limited door opening distance on the dangerous side of the door opening. Adaptively, at least re-entering step S3 after executing the door opening restriction action can mean that (when there is a danger of door opening and the user's door pushing operation meets the door opening restriction conditions) during the user's first pull of the door handle and push to open the door, if the user finds that there is resistance to opening the door and the door can only be partially opened and cannot be opened normally, and the user pulls the door handle and pushes the door again, then the user's action of pulling the door handle and pushing the door again is judged to determine whether it is still necessary to restrict the user's action of pulling the door handle and pushing the door again. This continues until a certain door pushing operation by the user no longer meets the door opening restriction conditions and there is no danger of door opening, then proceeding to the next step, i.e., step S5.

[0064] S5. Remove the door opening restriction to allow the doors to open normally.

[0065] In this context, removing door opening restrictions can refer to removing any restrictions that exist when the door is opened, so that the door can be opened normally.

[0066] In another specific embodiment, the driver takes the rear passengers to a movie theater. After arriving at the theater, the rear passengers need to open the right rear door to get out of the vehicle. The onboard camera detects a pedestrian continuously passing by the side and rear of the door. The onboard camera then captures multiple frames of images of the pedestrian outside the vehicle to obtain the pedestrian's trajectory information and inputs it into a pre-trained trajectory prediction model. The trajectory prediction model analyzes the pedestrian's trajectory information and finds that the pedestrian's trajectory one second later is less than 30cm from the vertical distance of the side door, indicating a danger when the door is opened. Subsequently, the onboard voice assistant provides a voice prompt: "The right rear door is dangerous when it is open," and the car's central control screen displays real-time image information of the right rear door. At this point, the passenger pulls the door handle to push the door and finds that the door opening is restricted and cannot be opened normally. The passenger then pulls the door handle again and finds that the door opening is still restricted. The passenger pulls the door handle again and pushes the door, and continues to judge whether the opening action meets the door restriction conditions. If the passenger's action of pulling the door handle again does not meet the door restriction conditions, then when the passenger pulls the door handle again and pushes the door, step S5 is entered, that is, the door opening restriction is lifted and the door opens normally.

[0067] In summary, this embodiment requires at least one door opening warning action during the process from detecting a door opening hazard to finally revoking the door opening restriction. It also determines whether at least one user door-pushing operation meets the door opening restriction conditions. The door can only be opened normally if and only if the user's door-pushing operation no longer meets the door opening restriction conditions and there is no door opening hazard. Under other conditions, user door opening will be restricted. Clearly, through the door opening warning and restriction process described above, this embodiment can provide users with multiple door opening warnings and protection measures after detecting a door opening hazard. This solves the problem that warning signals issued by existing vehicle door opening warning systems are easily ignored by users, making it difficult to guarantee user door opening safety. It improves the intuitiveness, safety, effectiveness, and environmental adaptability of vehicle door opening warnings, thus helping to ensure user door opening safety and improve the user's driving experience.

[0068] Based on the above embodiments or implementation methods, this embodiment adds and refines the vehicle door opening warning method of the aforementioned embodiments, but does not limit the present invention. In a specific implementation, optionally, step S3 includes at least the following steps:

[0069] S31. In response to the user's door-opening operation, determine whether the user's door-opening operation is the first time the door is opened;

[0070] S32. If the user's push-door operation is the first time the door is opened, then the door opening restriction condition is deemed to be met.

[0071] S33. If the user's door-pushing operation is not the first door-opening operation, then determine whether the interval between the user's door-pushing operation and the user's last door-pushing operation meets the first preset time condition.

[0072] S34. If the interval between the user's door-pushing operation and the user's last door-pushing operation does not meet the first preset time condition, then the door-opening restriction condition is deemed to be met.

[0073] In another specific implementation, optionally, before step S31, the method further includes:

[0074] S35. In response to the user's door-pushing operation, determine whether the total duration of the user's door-pushing operation meets the second preset time condition.

[0075] S36. If the total duration of the user pushing the door meets the second preset time condition, proceed to step S5; otherwise, proceed to step S31.

[0076] In another specific implementation, optionally, the user's door-pushing operation does not meet the door-opening restriction conditions, including at least:

[0077] The user's door-opening operation is not the first time the door has been opened, and the time interval between the user's door-opening operation and the user's last door-opening operation meets the first preset time condition.

[0078] In yet another specific implementation, optionally, after step S3, the method further includes:

[0079] S6. If the door opening restriction condition is met, then at least after the door opening restriction action is performed, in response to the user's door closing operation, re-enter step S1.

[0080] Based on the specific solutions of the above implementation methods Figure 2 This is a flowchart of another vehicle door opening warning method provided in an embodiment of the present invention, such as... Figure 2 As shown, the vehicle door opening warning method specifically includes the following steps:

[0081] S1. In response to a user's attempt to get out of the vehicle after it has stopped, detect whether there is a risk of opening the door.

[0082] S2. If there is a risk of the door being opened, execute the door opening warning action.

[0083] S35. In response to the user's door-pushing operation, determine whether the total duration of the user's door-pushing operation meets the second preset time condition.

[0084] S36. If the total duration of the user pushing the door meets the second preset time condition, proceed to step S5; otherwise, proceed to step S31.

[0085] The total duration of the user's door opening can be the time interval between the first time the user pulls the door handle and pushes the door open, and the most recent time the user pulls the door handle and pushes the door open. Adaptively, the second preset time condition can be adjusted according to the user's actual driving needs. It can be set by the user through touch screen input, voice recognition input, gesture recognition input, etc., or it can be a time condition preset in the vehicle system.

[0086] In addition, the specific method for timing the total time of the user pushing the door can be to start the total timer when the user pulls the door handle and pushes the door for the first time, and then record the time once each time the user pulls the door handle and pushes the door. The specific method for calculating the total time of the user pushing the door can be to obtain the total time of the user pushing the door by taking the difference between the time of the user's most recent time pulling the door handle and pushing the door and the time of the user's first time pulling the door handle and pushing the door.

[0087] S31. In response to the user's door-opening operation, determine whether the user's door-opening operation is the first time the door is opened.

[0088] S32. If the user's push-door operation is the first time the door is opened, then the door opening restriction condition is deemed to be met.

[0089] The first door opening operation can refer to the user's first action of pulling the door handle and pushing the door open after determining that there is a danger in opening the door.

[0090] S33. If the user's door-pushing operation is not the first door-opening operation, then determine whether the interval between the user's door-pushing operation and the user's last door-pushing operation meets the first preset time condition.

[0091] S34. If the interval between the user's door-pushing operation and the user's last door-pushing operation does not meet the first preset time condition, then the door-opening restriction condition is deemed to be met.

[0092] The specific setting method for the first preset time condition can be the same as that for the second preset time. This can be input by the driver via touchscreen clicks, voice recognition, or gesture recognition, or it can be a pre-set time condition within the vehicle's infotainment system. Adaptively, the interval between the user's door-opening operation and the user's last door-opening operation can refer to the time interval between the moment the user pulls the door handle and pushes the door and the moment the user last pulled the door handle and pushed the door. This interval can be obtained through a timer, and can be calculated by subtracting the current door-opening time from the previous door-opening time.

[0093] S6. If the door opening restriction condition is met, then at least after the door opening restriction action is performed, in response to the user's door closing operation, re-enter step S1.

[0094] Among them, the door opening restriction action can refer to restricting the door opening distance; if the door opening restriction condition is met, then at least after the door opening restriction action is executed, in response to the user's door closing operation, re-entering step S1 can refer to when the user finds that there is a distance restriction on the door opening when opening the door, the user pulls the door handle to restore the door to the closed state.

[0095] In addition, a specific implementation method for limiting door opening can be to limit the opening angle and thus the opening distance. For example, if the preset door opening limit distance is 20cm, the length of a typical sedan's front door is between 90 and 120cm, and the length of the rear door is between 80 and 110cm. Here, α1 is the door opening angle to be limited when the front door is 120cm, α2 is the door opening angle to be limited when the front door is 90cm, β1 is the door opening angle to be limited when the rear door is 110cm, and β2 is the door opening angle to be limited when the rear door is 80cm. Using trigonometric functions, we get α1 = 9.59°, α2 = 12.88°, β2 = 10.47°, and β2 = 14.48°. Therefore, it is only necessary to keep the front door opening angle between 9.59 and 12.88°; similarly, the rear door opening angle only needs to be kept between 10.47 and 14.48° to achieve a door opening angle within 20cm. The specific implementation method is as follows... Figure 5 As shown.

[0096] S4. If the user's door-pushing operation meets the door-opening restriction conditions, then at least after the door-opening restriction action is performed, the process will re-enter step S3 until the user's door-pushing operation is not the first door-opening operation, and the interval between the user's door-pushing operation and the user's last door-pushing operation meets the first preset time condition and there is no danger of opening the door, then proceed to step S5.

[0097] S5. Remove the door opening restriction to allow the doors to open normally.

[0098] In another specific embodiment, the driver takes a rear passenger to a subway station. After the vehicle arrives at the station, the passenger needs to open the right rear door to get out. The onboard camera detects a pedestrian continuously passing by on the side and rear. The onboard camera then captures multiple frames of images of the pedestrian outside the vehicle to obtain the pedestrian's trajectory information and inputs it into a pre-trained trajectory prediction model. After the trajectory prediction model analyzes the trajectory information of the pedestrian on the side and rear, the relative distance between the predicted trajectory information of the pedestrian and the door on that side is no more than 30cm (at this point, it is considered that there is a danger of opening the door). The onboard voice assistant prompts: "There is a danger of opening the right rear door." The car's central control screen displays real-time video images of that side door. At this moment, the passenger pulls the door handle and pushes the right rear door, and finds that there is obvious resistance when the right rear door is opened and the maximum opening distance of the door is 20cm (at this time, it is considered that the passenger is opening the door for the first time). According to the car's main clock, the passenger pushed the door at 16:24:03. Before this, the driver set the first preset time to 1 second and the second preset time to 2 seconds. In the following second, the passenger pulled the door handle and pushed the door multiple times and found that the door opening was always restricted and the door could not be opened normally (at this time, it is considered that the interval between the user's push operation and the user's last push operation does not meet the first preset time condition). At this time, the passenger noticed that there were still pedestrians passing by the right rear door. The passenger, through the real-time video footage of the door on that side displayed on the car's central control screen, discovered that the slow opening of the door was not actually dangerous. After confirming that it was safe, the passenger pulled the door handle again and pushed the right rear door. According to the car's main clock, the passenger pushed the door at 16:24:05. At this time, the passenger found that the door status had returned to normal and there was no limitation on the opening distance (at this point, it was assumed that the total duration of the user pushing the door met the second preset time condition), and the door could be opened normally.

[0099] In summary, this embodiment addresses the issue that existing vehicle door opening warning systems rely on visual and / or auditory warning signals that are easily ignored by drivers or passengers, even in situations where users are distracted by conversation (e.g., when a driver and passenger are paying fares) or in harsh environments (e.g., during thunderstorms or near construction sites), thus maintaining the risk of door opening. By adding a tactile dimension, the intuitiveness, safety, effectiveness, and environmental adaptability of the vehicle door opening warning system are improved, thus enhancing user safety when opening doors. Furthermore, this embodiment avoids unnecessary and continuous door restriction in situations where pedestrians are slowly passing by the door, thus preventing the door from remaining permanently locked and improving the user experience. Moreover, when door opening is dangerous, this embodiment can continuously restrict door opening for a preset time, preventing frequent opening and closing operations due to user impatience or negligence, thereby ensuring user safety when opening doors.

[0100] This invention also provides a vehicle door opening warning device. Figure 3 This is a schematic diagram of a vehicle door opening warning device provided in an embodiment of the present invention. This embodiment is applicable to dangerous scenarios involving vehicle door opening in various types of vehicles, such as gasoline-powered vehicles, pure electric vehicles, hybrid electric vehicles, plug-in hybrid electric vehicles, range-extended electric vehicles, and autonomous vehicles. The device can be implemented using software and / or hardware, and can be integrated into the vehicle's interior by incorporating it into the vehicle's infotainment system. Figure 3 As shown, the vehicle door opening warning device includes:

[0101] The door opening hazard detection module 110 is used to detect whether there is a door opening hazard in response to a user's intention to get out of the vehicle after the vehicle has stopped.

[0102] The door opening warning execution module 120 is used to execute a door opening warning action when the door opening danger detection module 110 detects a door opening danger.

[0103] The door opening restriction judgment module 130 is used to respond to the user's door pushing operation and determine whether the user's door pushing operation meets the door opening restriction conditions.

[0104] The door opening restriction execution module 140 is used to re-enter the door opening restriction judgment module 130 at least after executing the door opening restriction action when the user's door pushing operation meets the door opening restriction conditions, until the user's door pushing operation no longer meets the door opening restriction conditions and there is no danger of opening the door, and then enter the door opening restriction cancellation module 150.

[0105] The door opening restriction cancellation module 150 is used to cancel the door opening restriction so that the door can be opened normally.

[0106] Optionally, the door opening restriction judgment module 130 specifically functions to, in response to a user's door-pushing operation, determine whether the user's door-pushing operation is the first door-opening operation; if the user's door-pushing operation is the first door-opening operation, then it is determined that the door opening restriction condition is met; if the user's door-pushing operation is not the first door-opening operation, then it is determined whether the interval between the user's door-pushing operation and the user's last door-pushing operation meets a first preset time condition; if the interval between the user's door-pushing operation and the user's last door-pushing operation does not meet the first preset time condition, then it is determined that the door opening restriction condition is met.

[0107] Optionally, it also includes:

[0108] The judgment module 160 is used to respond to the user's door pushing operation and determine whether the total duration of the user pushing the door meets the second preset time condition; if the total duration of the user pushing the door meets the second preset time condition, the door opening restriction cancellation module 150 is entered; otherwise, the door opening restriction judgment module 130 is entered.

[0109] Optionally, the user's door-pushing operation does not meet the door-opening restriction conditions, including at least:

[0110] The user's door-opening operation is not the first time the door has been opened, and the time interval between the user's door-opening operation and the user's last door-opening operation meets the first preset time condition.

[0111] Optionally, the door opening restriction execution module 140 is further configured to, if the door opening restriction conditions are met, at least after executing the door opening restriction action, re-enter the door opening hazard detection module 110 in response to the user's door closing operation.

[0112] Optionally, the door opening warning action includes at least one of the following: increased door resistance on the dangerous side of the door, image display on the dangerous side of the door, and alarm sound prompt; the door opening restriction action includes at least one of the following: increased door resistance on the dangerous side of the door, and limited door opening distance on the dangerous side of the door.

[0113] The aforementioned vehicle door opening warning device can execute a vehicle door opening warning method provided in any embodiment or implementation of the present invention, and has the corresponding functional modules and beneficial effects of the method.

[0114] This embodiment provides a vehicle door opening warning device. First, a door opening hazard detection module detects whether a door opening hazard exists. Then, if the door opening hazard detection module detects a door opening hazard, a door opening warning execution module executes a door opening warning action. Finally, a door opening restriction judgment module determines whether the user's door pushing operation meets the door opening restriction conditions. If it does not meet the door opening restriction conditions, the door opens normally. If it meets the door opening restriction conditions, the door opening restriction execution module executes a door opening restriction action at least once, and then the door opening restriction judgment module determines whether subsequent user door pushing operations meet the door opening restriction conditions, until a user door pushing operation no longer meets the door opening restriction conditions and there is no door opening hazard. At this point, the door opening restriction cancellation module cancels the door opening restriction, and the door opens normally.

[0115] Therefore, in this embodiment, during the process from detecting the door opening hazard detection module to finally canceling the door opening restriction module, at least one door opening warning action needs to be executed, and at least one user door pushing operation needs to be determined whether it meets the door opening restriction conditions. The door can only be opened normally if and only if the user door pushing operation no longer meets the door opening restriction conditions and there is no door opening hazard. Under other conditions, user door opening will be restricted. Obviously, through the door opening warning and door opening restriction process involved in the above process, this embodiment can provide users with multiple door opening warnings and protection measures after detecting door opening hazard. It can solve the problem that the warning signals issued by existing vehicle door opening warning devices are easily ignored by users, making it difficult to ensure user door opening safety. It improves the intuitiveness, safety, effectiveness, and environmental adaptability of vehicle door opening warnings, which is conducive to ensuring user door opening safety and improving the user's driving experience.

[0116] Figure 4 This is a schematic diagram of the vehicle infotainment system provided in an embodiment of the present invention. Figure 4 A block diagram of an exemplary vehicle infotainment system 21 suitable for implementing embodiments of the present invention is shown. Figure 4 The vehicle infotainment system 21 shown is merely an example and should not impose any limitations on the functionality and scope of use of the embodiments of the present invention.

[0117] like Figure 4 As shown, the vehicle infotainment system 21 is presented in the form of a general-purpose computing device. The components of the vehicle infotainment system 21 may include, but are not limited to: radar 31, one or more processors or processing units 16, system memory 28, and bus 18 connecting different system components (including system memory 28 and processing unit 16).

[0118] Bus 18 represents one or more of several bus architectures, including a memory bus or memory controller, a peripheral bus, a graphics acceleration port, a processor, or a local bus using any of the various bus architectures. For example, these architectures include, but are not limited to, the Industry Standard Architecture (ISA) bus, the Micro Channel Architecture (MAC) bus, the Enhanced ISA bus, the Video Electronics Standards Association (VESA) local bus, and the Peripheral Component Interconnect (PCI) bus.

[0119] The vehicle infotainment system 21 typically includes a variety of computer system readable media. These media can be any available media that can be accessed by the vehicle infotainment system 21, including volatile and non-volatile media, and removable and non-removable media.

[0120] System memory 28 may include computer system readable media in the form of volatile memory, such as random access memory (RAM) 30 and / or cache memory 32. The vehicle infotainment system 21 may further include other removable / non-removable, volatile / non-volatile computer system storage media. By way of example only, storage system 34 may be used to read and write non-removable, non-volatile magnetic media (…). Figure 4 Not shown; usually referred to as a "hard drive"). Although Figure 4 Not shown, a disk drive for reading and writing to a removable non-volatile disk (e.g., a "floppy disk") and an optical disk drive for reading and writing to a removable non-volatile optical disk (e.g., a CD-ROM, DVD-ROM, or other optical media) may be provided. In these cases, each drive may be connected to bus 18 via one or more data media interfaces. Memory 28 may include at least one program product having a set (e.g., at least one) of program modules configured to perform the functions of the embodiments of the present invention.

[0121] A program / utility 40 having a set (at least one) of program modules 42 may be stored, for example, in memory 28. Such program modules 42 include—but are not limited to—an operating system, one or more application programs, other program modules, and program data. Each or some combination of these examples may include an implementation of a network environment. Program modules 42 typically perform the functions and / or methods described in the embodiments of the present invention.

[0122] The vehicle infotainment system 21 can also communicate with one or more external devices 14 (e.g., keyboard, pointing device, display 24, etc.), and with one or more devices that enable users to interact with the vehicle infotainment system 21, and / or with any device that enables the vehicle infotainment system 21 to communicate with one or more other computing devices (e.g., network card, modem, etc.). This communication can be performed through the input / output (I / O) interface 22. Furthermore, in this embodiment, the display 24 of the vehicle infotainment system 21 is not an independent entity, but is embedded in a mirror, so that when the display surface of the display 24 is not displaying anything, the display surface of the display 24 and the mirror surface visually blend together. Moreover, the vehicle infotainment system 21 can also communicate with one or more networks (e.g., local area network (LAN), wide area network (WAN), and / or public networks, such as the Internet) through the network adapter 20. Figure 4 As shown, network adapter 20 communicates with other modules of the vehicle infotainment system 21 via bus 18. It should be understood that, although... Figure 4 As not shown, other hardware and / or software modules can be used in conjunction with the vehicle infotainment system 21, including but not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data backup storage systems.

[0123] The processing unit 16 executes various functional applications and data processing by running programs stored in the system memory 28, such as implementing the vehicle door opening warning method provided in this embodiment of the invention: in response to a user's intention to get out of the vehicle after it stops, it detects whether there is a door opening hazard; if there is a door opening hazard, it executes a door opening warning action; in response to a user's door pushing operation, it determines whether the user's door pushing operation meets the door opening restriction conditions; if the user's door pushing operation meets the door opening restriction conditions, it responds again and determines whether subsequent user door pushing operations meet the door opening restriction conditions at least after executing the door opening restriction action, until a user door pushing operation no longer meets the door opening restriction conditions and there is no door opening hazard; after determining that the user's door pushing operation no longer meets the door opening restriction conditions and there is no door opening hazard, it cancels the door opening restriction to allow the vehicle door to open normally.

[0124] This invention also provides a computer-readable storage medium storing a computer program executable by an electronic device, which, when run on the electronic device, causes the electronic device to perform the steps of a vehicle door opening warning method.

[0125] This invention also provides a vehicle, the vehicle comprising: at least one electronic device, at least one processor; and a storage medium communicatively connected to the at least one processor; wherein the storage medium stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one electronic device to perform the method steps described in the above embodiments.

[0126] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
