[0038] As described above, the current door control method, that is, the driver or passenger directly pushes the door to open it, does not take into account the dynamic changes of the environment, especially in the absence of sufficient observation or judgment, it is easy to collide with other road users. This may not only cause physical harm to road users, but also lead to traffic congestion and legal liability disputes, becoming a difficult point in urban traffic safety management.

[0039] After research, the inventor has proposed a door control method, device and vehicle. The door control method can obtain the vehicle's external environment information when the vehicle is in a parking state and determine whether there is an obstacle within the vehicle's detection range based on the external environment information. If there is an obstacle, the first prompt information is triggered, thereby effectively reminding the user in the vehicle to pay attention to changes in the surrounding environment and take a more cautious attitude to control the door opening. In addition, if the time difference from the triggering time of the first prompt information to the current time is less than or equal to the first duration, the door is kept locked, thereby effectively avoiding the danger to other road users caused by suddenly opening the door.

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] See also Figure 1 , which is a flow chart of a door control method provided by an embodiment of the present application. The method comprises:

[0042] S101: When the vehicle is in a parking state, obtain the vehicle's external environment information.

[0043] The parking state refers to the state where the vehicle is stationary, the engine is not running or is idling, and the driver or the automatic system is preparing to park or has already parked.

[0044] The external environment information refers to the spatial information around the vehicle, including but not limited to the existence, distance, type and location of obstacles. Specifically, when the vehicle is parked, the external environment information of the vehicle can be obtained through sensors and cameras installed around the vehicle (such as the front bumper, rear bumper, side, etc.).

[0045] Among them, the sensors include ultrasonic sensors, which are installed around the vehicle and need to ensure all-round coverage. Ultrasonic sensors are suitable for close-range detection (such as a few centimeters to a few meters), and are particularly effective for detecting parking space boundaries and low obstacles (such as curbs and children's toys). Its working principle is that the ultrasonic sensor emits ultrasonic pulses, and the sound waves are reflected back after encountering an obstacle. The distance between the obstacle and the vehicle is determined by calculating the time difference between transmission and reception.

[0046] The sensors also include radar sensors, which are also installed around the vehicle and need to ensure all-round coverage. Radar sensors can penetrate adverse weather conditions such as rain, snow, and fog, and have a long detection distance (up to tens of meters or even hundreds of meters), making them suitable for medium and long-distance obstacle detection. Its working principle is that the radar sensor emits electromagnetic waves (usually radio waves), which are reflected back after encountering obstacles, and the distance between the obstacle and the vehicle is calculated by measuring the time difference and wave speed.

[0047] Cameras are also installed around the vehicle to ensure full coverage. The cameras can capture image data around the vehicle, which can then be processed by image processing algorithms (such as edge detection, shape recognition, etc.) to identify obstacle types (such as pedestrians, vehicles, trees, etc.) and locations.

[0048] S102: When it is determined based on the external environment information that there is an obstacle within the detection range of the vehicle, a first prompt message is triggered, wherein the first prompt message is used to remind the user that there is a safety risk in opening the door.

[0049] The detection range refers to the area that can be detected by sensors and cameras installed outside the vehicle. It can also be a preset safety area based on factors such as vehicle size and parking environment, such as a rectangular or polygonal area around the vehicle. Setting a reasonable detection range can ensure that when an obstacle enters the range, the vehicle can detect it in time and trigger a prompt message.

[0050] Obstacles include moving obstacles (such as pedestrians, bicycles, pets, etc.) and fixed obstacles (such as walls, trees, other vehicles, etc.).

[0051] If an obstacle enters the detection range, it is considered that there is a potential safety risk and the first prompt information needs to be triggered to remind the user that there is a safety risk in opening the door.

[0052] In a specific implementation, the first prompt information may be a visual prompt, such as displaying a warning icon or text message through a vehicle display module (such as a central control screen), an instrument panel module, and a rearview mirror module, to intuitively remind the user to pay attention to obstacles outside the door. In another specific implementation, the first prompt information may also be an auditory prompt, such as playing an alarm sound or voice prompt (such as "Please note that there is an obstacle outside the door") through a speaker in the car to inform the user of a safety risk. In another specific implementation, the first prompt information may also be a tactile prompt, such as providing additional physical feedback through seat vibration or steering wheel vibration, so that the user can feel the potential safety risk. It should be noted that this application does not limit the specific first prompt information, and the most appropriate prompt method can be selected according to the actual situation or a combination of multiple prompt methods can be used.

[0053] S103: When it is detected that the user unlocks the vehicle door, and the time difference between the triggering time of the first prompt information and the current time is less than or equal to the first time duration, the vehicle door is controlled to be in a locked state.

[0054] The first time duration (T_max) is a time threshold set according to the vehicle's safety strategy and actual application requirements, and is used to determine whether the user attempts to unlock the door within a short period of time after receiving the first prompt message, for example, it can be 3 seconds, 5 seconds, etc.

[0055] Specifically, when an obstacle is detected and the first prompt message is triggered, the current timestamp (T1) is recorded. This timestamp indicates that the user has been informed that there is an obstacle outside the door. When it is detected that the user attempts to unlock the door, the current timestamp (T2) is recorded again. This timestamp indicates that the user has taken the action of opening the door. Subsequently, the time difference between the two timestamps is calculated (ΔT=T2-T1). This time difference reflects the time interval between the user receiving the prompt message and attempting to unlock the door. Next, the calculated time difference (ΔT) is compared with the first duration (T_max). If ΔT≤T_max, it is considered that the user attempts to unlock the door in a short time, which may mean that the user does not fully pay attention to the first prompt message. At this time, the vehicle will take measures to keep the door locked to prevent collision or injury caused by not noticing the obstacle. If ΔT>T_max, it is considered that the user attempts to unlock the door after a sufficiently long time, which may mean that the user has noticed the first prompt message and made a corresponding judgment. At this time, the vehicle will not prevent the door from being unlocked, and the user can open the door normally.

[0056] In summary, the embodiment of the present application provides a door control method, which can obtain the vehicle's external environment information when the vehicle is in a parking state and determine whether there is an obstacle within the vehicle's detection range based on the external environment information. If there is an obstacle, the first prompt information is triggered, thereby effectively reminding the user in the vehicle to pay attention to changes in the surrounding environment and take a more cautious attitude to control the door opening. In addition, if the time difference from the triggering time of the first prompt information to the current time is less than or equal to the first duration, the door is kept locked, thereby effectively avoiding the danger to other road users caused by suddenly opening the door.

[0057] See also Figure 2 , which is a flow chart of another door control method provided by an embodiment of the present application. The method comprises:

[0058] S201: When the duration of the vehicle being in the parking state is less than a second duration, the blind spot monitoring system module obtains the external environment information of the vehicle.

[0059] The blind spot monitoring system is used to monitor the blind spots around the vehicle (i.e. areas that are difficult for the driver or passengers to directly observe) when the vehicle is driving or parked, so as to reduce the risk of collision caused by blind spots.

[0060] Specifically, the vehicle's wheel speed sensor can be used to monitor the vehicle's speed in real time. When the vehicle speed drops to zero, the blind spot monitoring system determines that the vehicle is in a parked state and starts timing (T0), marking it as the time point when the vehicle completely stops. Starting from the time point when the vehicle completely stops (T0), within the next second period of time (for example, within 10 minutes), the blind spot monitoring system module is activated and continues to obtain external environmental information through devices such as cameras, radars or laser radars (LiDAR) to monitor the blind spots around the vehicle.

[0061] It should be noted that when the timer reaches the preset second time length (for example, 10 minutes), if the vehicle is still not started, the blind spot monitoring system automatically stops data collection and processing and enters a low power mode or sleep state until the vehicle is started again or other reactivation conditions are met.

[0062] S202: The blind spot monitoring system module determines whether there is an obstacle within the detection range of the vehicle based on the external environment information. If yes, execute step S203; if not, control the door to be in the open state.

[0063] In a specific implementation, the detection range includes a first detection range and a second detection range, corresponding to the left and right sides of the vehicle, respectively. The first detection range is the range surrounded by the first left side boundary, the first right side boundary, the first front side boundary and the first rear side boundary. Among them, the first left side boundary is parallel to the body of the vehicle and the distance from the body is less than the first distance (e.g., 50 cm), the first right side boundary is parallel to the body and the distance from the body is less than the second distance (e.g., 30 cm), the first front side boundary is perpendicular to the body and the distance from the door of the vehicle is less than the third distance (e.g., 1 meter), the first rear side boundary is perpendicular to the body and the distance from the rear of the vehicle is less than the fourth distance (e.g., 2 meters), the first distance is greater than the second distance, and the third distance is less than the fourth distance. Similarly, the second detection range is the range surrounded by the second left side boundary, the second right side boundary, the third front side boundary and the fourth rear side boundary. Among them, the first left side boundary is a boundary parallel to the vehicle body and the distance from the vehicle body is less than the second distance, the second left side boundary is a boundary parallel to the vehicle body and the distance from the vehicle body is less than the first distance, the first front side boundary is a boundary perpendicular to the vehicle body and the distance from the vehicle door is less than the third distance, the first rear side boundary is a straight line perpendicular to the vehicle body and the distance from the rear of the vehicle is less than the fourth distance, the first distance is greater than the second distance, and the third distance is less than the fourth distance.

[0064] For ease of understanding, combined Figure 3 For explanation: See Figure 3 , which is a schematic diagram of a vehicle detection range provided by an embodiment of the present application. Figure 3It can be seen that the detection range is defined by a series of virtual lines (A, B, C, D, E, F, G, H, J, K, L, M, N, O).

[0065] For the detection range on the left side of the vehicle (i.e., the first detection range mentioned above), when there is an object completely behind the C line (i.e., the first front boundary) and to the left of the F line (i.e., the first right boundary), and any part of the object is located in front of the B line (i.e., the first rear boundary) and to the right of the G line (i.e., the first left boundary), it is determined that there is an obstacle in the detection range of the vehicle. For the detection range on the right side of the vehicle (i.e., the second detection range), when there is an object completely behind the C line (i.e., the second front boundary) and to the right of the K line (i.e., the second left boundary), and any part of the object is located in front of the B line (i.e., the second rear boundary) and to the left of the L line (i.e., the second right boundary), it is determined that there is an obstacle in the detection range of the vehicle.

[0066] If there is an obstacle in the detection range on the left or right side, then step S203 is executed. If there is no obstacle in the detection range on the left or right side, then the door is controlled to be in an open state, allowing the driver or passenger to enter and exit the vehicle.

[0067] S203: The blind spot monitoring system module sends a first prompt message to the vehicle display screen module, the instrument panel module and the rearview mirror module through the bus, wherein the first prompt message is used to remind the user that there is a safety risk in opening the door.

[0068] Once a safety risk is determined, the blind spot monitoring system module will generate the first prompt information. This information is then sent to the vehicle display module, instrument panel module and rearview mirror module through the controller area network (CAN) bus. Among them, the CAN bus is a communication protocol widely used in automotive electronic systems with high reliability and real-time performance. CAN bus communication ensures the real-time and reliability of the transmission of the first prompt information, ensuring that each module can receive the prompt information synchronously.

[0069] It should be noted that when the blind spot monitoring system module sends the first prompt information to the vehicle display module, the instrument panel module and the rearview mirror module through the bus, the blind spot monitoring system module also needs to record the timestamp (T_alert) of the triggering time of the first prompt information.

[0070] S204: The vehicle display screen module, the instrument panel module and the rearview mirror module display the obstacle information in response to the first prompt information.

[0071] The vehicle display module, instrument panel module and rearview mirror module receive the first prompt information sent by the blind spot monitoring system module through the CAN bus. After receiving the first prompt information, the vehicle display module, instrument panel module and rearview mirror module will display the information of the obstacle to the user in different ways according to the specific content of the first prompt information. This may include: text prompts (for example, "Please note that there is an obstacle outside the door, please do not open the door"), icon prompts (using specific warning icons, such as red exclamation marks or warning lights) and dynamic images (animations or schematic diagrams showing the location and movement direction of obstacles). In this way, the driver or passenger can be reminded before the owner is ready to open the door, so that the driver or passenger can promptly notice the potential dangers around the vehicle and take appropriate preventive measures to avoid collision accidents.

[0072] S205: When the vehicle body controller module detects that the user unlocks the vehicle door in the first manner, a first unlocking instruction is sent to the blind spot monitoring system.

[0073] When the vehicle is parked, if the user attempts to unlock the door in the first way (for example, pulling the inner door handle twice), the body controller module will generate a first unlock instruction after detecting the user's unlock operation. The first unlock instruction includes the user's unlock request and the timestamp (T_unlock) of the unlock operation. The timestamp (T_unlock) of the unlock operation is used to record the exact time when the user performs the unlock operation, so as to calculate the time difference later. Subsequently, the body controller module transmits the first unlock instruction to the blind spot monitoring system through an internal communication mechanism (such as a CAN bus).

[0074] S206: When the blind spot monitoring system determines according to the first unlocking instruction that the time difference between the triggering time of the first prompt information and the current time is less than or equal to the first duration, a second prompt information is sent to the body controller, and the second prompt information is used to prompt the body controller to control the door to be in a locked state.

[0075] After receiving the first unlocking instruction, the blind spot monitoring system will extract the timestamps (T_unlock) of the unlocking request and the unlocking operation by parsing the first unlocking instruction. Then, according to the timestamp (T_alert) of the triggering time of the first alert information and the timestamp (T_unlock) of the unlocking operation recorded previously, the time difference (ΔT = T_unlock-T_alert) is calculated. This time difference represents the time interval between the blind spot monitoring system sending the first alert information and the user trying to unlock the door.

[0076] Subsequently, the blind spot monitoring system compares the calculated time difference ΔT with the first duration T_max. The first duration T_max is a threshold used to determine whether the user attempts to unlock the door in a short period of time. If ΔT≤T_max, it is considered that the user attempts to unlock the door in a short period of time, and there may be a safety risk at this time (for example, the obstacle may still be near the door). Therefore, the blind spot monitoring system will send a second prompt message to the body controller, prompting the body controller to control the door to be in a locked state to prevent the door from being unlocked. If ΔT>T_max, it is considered that the user attempts to unlock the door after a sufficiently long time, and it can be considered that the previous safety risk has been eliminated (for example, the obstacle may have left the vicinity of the door). Therefore, the blind spot monitoring system will not prevent the door from being unlocked.

[0077] In some specific implementations, the first duration T_max is determined as follows:

[0078] First, the blind spot monitoring system determines whether there is an obstacle within the detection range of the vehicle based on the external environment information, and determines the position and moving speed of the obstacle. Secondly, based on the position and moving speed of the obstacle, the moving time of the obstacle to the door of the vehicle is calculated. Finally, the first time length T_max is determined based on the moving time. It should be noted that in order to ensure safety, the first time length T_max is usually set to be shorter than the moving time, so as to leave enough time to assess the safety risk before the user tries to unlock the door.

[0079] S207: The body controller controls the mechanical door lock to prevent the door from opening in response to the second prompt information.

[0080] After receiving the second prompt message sent by the blind spot monitoring system module, the body controller needs to control the mechanical door lock to ensure that the door remains locked to ensure that the door will not be accidentally opened when there is a potential safety risk, thereby avoiding a collision accident.

[0081] S208: When the vehicle body controller module detects that the user unlocks the vehicle door by the second method, the vehicle door is controlled to be in an open state.

[0082] In some emergency situations, the user may need to open the door immediately for evacuation or other emergency operations. In order to ensure that the door can be unlocked quickly and safely in this situation, the user can execute the second method (for example, normally the door can be opened by gently pulling the inner opening handle twice, but in this special situation, it needs to be pulled continuously 3-4 times to open the door), so that when the body controller detects that the user unlocks the door through the second method, the door is controlled to be in the open state, thereby meeting the needs in emergency situations.

[0083] It should be noted that after the body controller module controls the door to be in the open state, it can also inform the user that the door has been unlocked and remind the user to pay attention to safety through the vehicle display screen, voice prompt or vibration feedback. For example, the vehicle display screen displays a prompt message such as "The door is unlocked, please open the door carefully".

[0084] In summary, the embodiment of the present application provides a door control method, which can obtain the vehicle's external environment information when the vehicle is in a parking state and determine whether there is an obstacle within the vehicle's detection range based on the external environment information. If there is an obstacle, the first prompt information is triggered, thereby effectively reminding the user in the vehicle to pay attention to changes in the surrounding environment and take a more cautious attitude to control the door opening. In addition, if the time difference from the triggering time of the first prompt information to the current time is less than or equal to the first duration, the door is kept locked, thereby effectively avoiding the danger to other road users caused by suddenly opening the door.

[0085] See also Figure 4 , which is a schematic diagram of a vehicle door control device provided by an embodiment of the present application. The vehicle door control device 400 comprises: an information acquisition module 401 , an information prompt module 402 and a vehicle door control module 403 .

[0086] The information acquisition module 401 is used to acquire the vehicle's external environment information when the vehicle is in a parking state;

[0087] The information prompt module 402 is used to trigger a first prompt message when it is determined that there is an obstacle within the detection range of the vehicle according to the external environment information, wherein the first prompt message is used to prompt the user that there is a safety risk in opening the door;

[0088] The door control module 403 is used to control the door to be in a locked state when it is detected that the user unlocks the door and the time difference between the triggering time of the first prompt information and the current time is less than or equal to the first time length.

[0089] In some specific implementations, the detection range includes a first detection range, which is a range surrounded by a first left side boundary, a first right side boundary, a first front side boundary and a first rear side boundary, wherein the first left side boundary is a boundary parallel to the body of the vehicle and a distance from the body is less than a first distance, the first right side boundary is a boundary parallel to the body and a distance from the body is less than a second distance, the first front side boundary is a boundary perpendicular to the body and a distance from a door of the vehicle is less than a third distance, the first rear side boundary is a straight line perpendicular to the body and a distance from the rear of the vehicle is less than a fourth distance, the first distance is greater than the second distance, and the third distance is less than the fourth distance.

[0090] In some specific implementations, the first duration determination unit is specifically as follows:

[0091] A first determination unit, configured to determine the position and moving speed of an obstacle when it is determined that there is an obstacle within the detection range of the vehicle according to the external environment information;

[0092] A second determining unit is used to determine the moving time of the obstacle to the door of the vehicle according to the position and moving speed of the obstacle;

[0093] The third determining unit is used to determine a first duration according to the moving time, wherein the first duration is shorter than the moving time.

[0094] In some specific implementations, the information prompt module 402 is specifically used to: when it is determined that there is an obstacle within the detection range of the vehicle based on the external environment information, control the vehicle's onboard display screen module, instrument panel module and rearview mirror module to display the first prompt information.

[0095] In some specific implementations, the door control module 403 is specifically used to: when it is detected that the user unlocks the door in a first manner, and the time difference between the triggering time of the first prompt information and the current time is less than or equal to the first time length, control the door to be in a locked state;

[0096] The door control module 403 is also used to control the door to be in an open state when it is detected that the user unlocks the door in a second manner.

[0097] In summary, the embodiment of the present application provides a door control device, which can obtain the vehicle's external environment information when the vehicle is in a parking state and determine whether there is an obstacle within the vehicle's detection range based on the external environment information. If there is an obstacle, the first prompt information is triggered, thereby effectively reminding the user in the vehicle to pay attention to changes in the surrounding environment and take a more cautious attitude to control the door opening.
