[0020] Reference numerals: Door control system 400, monitoring module 401, control module 402. Detailed Implementation

[0021] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While some embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this application. It should be understood that the drawings and embodiments of this application are for illustrative purposes only and are not intended to limit the scope of protection of this application.

[0022] It should be understood that the steps described in the method embodiments of this application may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this application is not limited in this respect.

[0023] As described in the background section, the closing process of vehicle doors causes changes in cabin air pressure. These pressure fluctuations can easily cause discomfort such as ear pain, tinnitus, and dizziness in infants, the elderly, and passengers with ear diseases. In severe cases, it can even cause hearing damage. Currently, there are mainly methods such as electric suction doors, electric doors, and window linkage control to improve vehicle door closing. Electric suction doors mainly use motors to complete the closing action, while electric doors complete the closing action by outputting a constant closing force. However, electric suction doors and electric doors have high overall configuration costs and are mostly only equipped in high-end models. Neither of them is specifically optimized for cabin air pressure fluctuations. The constant low-speed closing mode can also affect daily use efficiency. Window control methods alleviate cabin pressure by finely adjusting the window opening, but these methods have control delays and are easily affected by external environmental interference, and cannot fundamentally solve the discomfort caused by air pressure changes.

[0024] To address the shortcomings of the aforementioned door closing control methods, this invention proposes a door control method that can solve the problems of cabin air pressure fluctuations caused by door closing, which can easily lead to health problems such as tinnitus and ear pain in infants, the elderly, and other passengers with ear discomfort. It also addresses issues such as high cost, weak protective measures, control delays, and the inability to intelligently adapt to different scenarios. This new method can differentiate and switch door closing modes based on the scenario without changing user habits, ensuring door closing efficiency under normal conditions while mitigating air pressure fluctuations. This reduces physical discomfort for sensitive passengers and improves the safety of door use.

[0025] The following is for reference. Figures 1-3 This application describes a door control method provided by an embodiment.

[0026] like Figure 1 The diagram shown is a flowchart illustrating a door control method according to an embodiment of this application.

[0027] Step S101: Monitor the opening status of the car door. When the car door is in the open state, determine whether there is a target object based on the weight change information on the seat inside the car.

[0028] Specifically, when the system detects that the car door is open, it immediately retrieves the data collected by the weight sensors under each seat in the vehicle, compares the weight values ​​of the seats before and after the door is opened to calculate the weight change, and then combines it with a preset weight threshold range to determine whether there is a target object in the vehicle.

[0029] Step S102: Detect whether a door closing operation exists. When a door closing operation is detected, in response to determining that the target object exists, control the door to close in a first mode. In response to determining that the target object does not exist, control the door to close in a second mode. In the first mode, the closing speed of the door is lower than the closing speed in the second mode.

[0030] Specifically, when the system detects a door closing operation, if it determines that a target object is inside the vehicle, it controls the door to enter the first closing mode, increasing resistance and reducing the closing speed by adjusting the adjustable damper at the door hinge. If it determines that no target object is inside the vehicle, it activates the second closing mode, allowing the door to close at the normal speed.

[0031] like Figure 2 The diagram shown is a general logic schematic of a door control method according to an embodiment of this application. After the door action is initiated, the system first determines the action type. If it is a closing action, the system collects the door movement speed in real time through a Hall sensor. The Hall sensor can capture the dynamic changes of the door, calculate the target damping force, and output a PWM current to the magnetorheological hinge. By changing the current signal, the damping magnitude of the magnetorheological hinge is adjusted, thereby controlling the closing resistance. When there are sensitive passengers such as infants or the elderly, the closing speed is slowed down by increasing the damping, allowing the cabin air pressure to rise gradually and avoiding ear discomfort. Even when there is no need for protection, the system can maintain normal closing efficiency and reduce the impact of the door on the surrounding environment. Mechanical impact on the door lock; if it is an opening action, the system simultaneously activates millimeter-wave radar to scan the door opening path and detect whether there is an obstacle. If an obstacle is detected, the electromagnetic lock is immediately activated, which can quickly lock the door's movement state, prevent the door from continuing to open, and trigger an audible and visual alarm to remind the user. If no obstacle is detected, the normal opening process is executed. When the door enters the closing critical stage, the system will use laser array scanning and pressure sensing to confirm whether there is a foreign object. If a foreign object is found, the reverse drive is immediately executed, controlling the door to slightly retract in the opening direction to avoid pinching people or damaging items, and an alarm is issued. If there is no foreign object, the door is directly locked.

[0032] As an optional embodiment, determining whether a target object exists based on weight change information on the seats inside the vehicle includes: obtaining the weight change value on the seats inside the vehicle before and after the door is opened; comparing the weight change value with a preset threshold range; and determining that a target object exists in response to the weight change value falling within the preset threshold range.

[0033] Specifically, the vehicle controller reads data from the weight sensors under each seat before and after the door opens, calculating the weight change of the seats inside the vehicle. This change only reflects the load increase or decrease caused by getting in and out of the vehicle, effectively avoiding interference from dynamic factors such as vehicle body swaying and road bumps during door opening and closing, ensuring the accuracy and validity of the data. The system compares this weight change value with a preset threshold range. This threshold range is not a fixed value but is pre-defined based on the typical weight ranges of sensitive groups requiring special protection, such as infants and young children. For example, based on the weight distribution data of children of different age groups, a reasonable range is set to fit the lowest weight of infants to the average weight of young children. At the same time, a certain amount of redundancy is reserved at the upper limit of the threshold to adapt to the weight change scenario of the target person carrying small personal items, and can filter the interference of non-target heavy objects such as suitcases, backpacks, and shopping bags. When the weight change value exceeds the preset threshold range, the system will judge... If the load is determined to be a non-target heavy object, the comfort closing mode will not be triggered. When the weight change value falls within the preset threshold range, the system can accurately identify the new load as a target object that needs protection, determine that there is a target object inside the vehicle, and provide an accurate judgment basis for controlling the door to close in the first mode at a low speed. This method does not require additional vision or radar sensors, and can achieve target object recognition only through the weight sensor built into the seat, which reduces the system hardware cost, avoids the recognition error of vision sensors in backlight, occlusion, and low light scenarios, and improves the reliability and adaptability of target object detection.

[0034] As an optional embodiment, the method further includes: obtaining the weight range of the target object; and determining a preset threshold range based on the weight range.

[0035] Specifically, the target audience is primarily infants and young children, who are sensitive to air pressure fluctuations when car doors close, with a weight range of approximately 10-20 kg. By combining the detection accuracy of the seat weight sensors, vehicle operating conditions, and weight fluctuations caused by small personal items during entry and exit, a corresponding preset threshold range is set. This covers the weight change data for the vast majority of sensitive occupants requiring special protection. The system can effectively identify load changes on the seats, distinguishing between passenger entry / exit and item handling scenarios. It filters out weight fluctuation interference from non-target heavy objects such as suitcases, backpacks, handbags, and large shopping items, preventing the low-speed door closing mode from being mistakenly triggered by heavy loads.

[0036] As an optional embodiment, controlling the door to close in a first mode includes: controlling an increase in the damping force of the door to reduce the closing speed of the door to a preset safe speed.

[0037] As an optional embodiment, the method further includes adjusting the damping force by means of an adjustable damper disposed at the door hinge.

[0038] Specifically, such as Figure 3 The diagram illustrates the door closing operation of a door control method according to an embodiment of this application. The body controller sends a control signal to the adjustable damper at the door hinge. Upon receiving the command, the damper actively increases its working damping force, using the damping resistance to intervene in the door's movement state and gradually reduce the actual closing speed of the door to a pre-calibrated safe speed range. When the door closes at a low speed, the air in the sealed space inside the passenger compartment can slowly circulate outwards through the door gap, significantly reducing the violent air pressure fluctuations caused by the rapid closing of the door. This effectively avoids sudden changes in air pressure that could irritate sensitive passengers such as infants and children, preventing discomfort such as ear fullness and eardrum pain. The adjustable damper is preferably a magnetorheological fluid damper, which has the advantages of rapid response, high resistance adjustment accuracy, and stepless continuous adjustment. It can change the internal medium state in real time according to the electrical signal output by the body controller, flexibly adapting to the resistance adjustment requirements under different operating conditions. Under the buffering effect of damping force, the impact force when the door and door lock mechanism come into contact is significantly reduced, effectively weakening the mechanical impact at the moment of contact, slowing down the wear rate of structural components such as door locks and door hinges, extending the service life of related parts, and also significantly reducing the impact noise and vibration noise generated during the closing process, further improving the overall vehicle safety and driving experience. The entire control process works together to ensure the safety and comfort of passengers while also effectively protecting the mechanical structure of the door.

[0039] As an optional embodiment, the method further includes: detecting whether there is a foreign object in the closing path of the door during the closing process; and performing an anti-pinch response operation in response to the detection of a foreign object.

[0040] As an optional embodiment, the anti-pinch response operation includes: controlling the door to stop closing, controlling the door to move back a preset distance in the opening direction, or stopping the door closing action, and outputting an alarm signal.

[0041] Specifically, the laser array on the inside of the car door scans at a high frequency of 100Hz, and a single complete scan takes only 10ms. Combined with the pressure sensor's dual threshold judgment of contact force changes, it jointly monitors whether there are hands, feet or other foreign objects on the closing path. When the contact force change reaches the first threshold (the first threshold can be set as the pressure change rate ΔP≥15N / cm² / ms, which can be adjusted according to the actual situation), it indicates that the door closing area has come into contact with an obstacle and there is a risk of being pinched. The system will immediately issue a command to control the door to stop the current closing action, and at the same time, it will provide a prompt to remind the driver and passengers to pay attention to potential safety hazards around the door. If the foreign object is not removed in time, the door will continue to move, causing the contact force to increase continuously. When the change in contact force reaches the secondary threshold (the secondary threshold can be set as a pressure change rate ΔP ≥ 30 N / cm² / ms, which can be adjusted according to actual conditions), the presence of a foreign object in the path is confirmed. The system controls the drive mechanism to move the door in the opening direction by a preset retraction stroke, relying on the reverse driving force to slightly retract the door, releasing the pressure state on the foreign object. Alternatively, depending on the working conditions, the door can be directly locked, and the audible and visual alarm device will be triggered, continuously issuing warning signals through conspicuous light prompts and warning sounds. The entire protection mechanism will remain in working condition, and the alarm and door lock status will not be automatically released until the driver and passengers manually intervene and remove the foreign object from the path. Only then will the system release the protection logic and allow the door to close again. The entire detection and protection process is rapid and hierarchical, progressing from risk warning to emergency protection, comprehensively preventing situations where people are pinched or objects are crushed by the door, thus improving the safety performance of the door during use.

[0042] In summary, the vehicle door control system provided in this application includes: a monitoring module configured to monitor the opening state of the vehicle door, and when the door is open, to determine whether a target object exists based on weight change information on the seats inside the vehicle; and a control module configured to detect whether a door closing operation is detected, and when a door closing operation is detected, to control the door to close in a first mode in response to the determination that a target object exists, and to control the door to close in a second mode in response to the determination that no target object exists; wherein, the closing speed of the door in the first mode is lower than the closing speed in the second mode. Therefore, this application can solve the problems of cabin air pressure fluctuations caused by door closing that can easily lead to health problems such as tinnitus and ear pain in infants, the elderly, and passengers with ear discomfort, as well as the problems of high cost, weak protective targeting, control delays, and inability to intelligently adapt to scenarios associated with related solutions. It can differentiate and switch closing modes according to scenarios without changing user habits, ensuring closing efficiency in normal conditions and reducing air pressure fluctuations, reducing physical discomfort for sensitive passengers, and improving the safety of vehicle door use.
