Description

Technical Field

[0001] This invention belongs to the field of automotive technology, and in particular relates to a vehicle door closing optimization control method and system. Background Technology

[0002] When a car door closes, it forces outside air into the vehicle. If other doors, the trunk, and windows are also closed, the only way for the air inside the car to escape is through pressure relief valves located on both sides of the rear bumper and other gaps in the body. However, with advancements in automotive technology, vehicle sealing has improved, reducing exhaust paths other than pressure relief valves. Since the pressure relief valves have limited capacity, the increased air pressure inside the car leads to greater force required to close the door and a noticeable increase in ear pressure for passengers. When the air conditioning is on and in external circulation mode, in addition to the air brought in through the door, the air conditioning system also continuously draws air into the car when the door is closed. This further increases ear pressure at the same speed, requiring even more force to close the door, which further impacts the passenger experience.

[0003] If issues with door closing ear pressure and force occur late in the vehicle development process, modifying the pressure relief valve or interior exhaust path at this stage requires altering the existing design, resulting in significant waste of mold and development costs. Furthermore, since other surrounding environmental factors are often fixed, changes are frequently impossible. Reducing overall vehicle sealing performance can lead to NVH (noise, vibration, and harshness) and water / dust ingress problems. Therefore, it is necessary to address the issues of excessive door closing force and increased passenger ear pressure caused by air compression during door closure, which negatively impact the passenger experience, without altering the vehicle's original structure. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a vehicle door closing optimization control method and system to solve the problem of large closing force and increased ear pressure on passengers caused by air compression when the door is closed.

Furthermore, "first" and "second" are used to distinguish different objects and are not intended to describe a specific order.

[0025] Please see Figure 1 A flowchart illustrating a vehicle door closing optimization control method provided in this embodiment of the invention includes:

[0026] S101. Obtain the vehicle start / stop status and the opening / closing status of the doors, windows, sunroof, and trunk;

[0027] The opening and closing of vehicle doors, windows, sunroof, and trunk will affect the airtightness of the vehicle's interior space. When any of these parts are open, the air squeezed into the vehicle when the door is closed may be expelled. In this case, there is no need to intervene in controlling the air conditioning and windows.

[0028] Based on the vehicle's own sensing devices, the central control system can collect information on the vehicle's start-stop status, as well as the opening and closing status of doors, windows, sunroof, and trunk. The central control system can obtain the vehicle's current start-stop status and the opening and closing information of doors and windows based on the CAN bus.

[0029] S102. If the vehicle is running and all doors, windows, sunroof, and trunk are closed, when any door of the vehicle is detected to be open, the air conditioning intake mode is adjusted according to the air conditioning circulation status and air intake volume.

[0030] The air conditioning circulation state includes internal circulation and external circulation, and the air intake volume is the air intake volume of the air conditioner, which can generally be measured by the setting.

[0031] When the vehicle is in the starting state (transmitter starts or vehicle is powered on), it reads the opening and closing signals of the doors, sunroof, trunk, and window glass raising and lowering signals. After detecting that the door is open, it controls and adjusts the air conditioning or windows.

[0032] When the vehicle doors, windows, sunroof, and trunk are all closed, if any door is detected to be open, the system will obtain information on whether the air conditioning is on, the air conditioning circulation mode, and the air conditioning air intake, and then adjust the air conditioning air intake mode accordingly.

[0033] Specifically, if the current air conditioning circulation mode is internal circulation and the air conditioning is not turned on, switch the air conditioning intake mode to external circulation and open the foot vent.

[0034] If the current air conditioning circulation mode is internal circulation and the air conditioner is on with the air intake volume lower than the preset level, then switch the air intake mode of the air conditioner to external circulation.

[0035] If the current air conditioning circulation mode is internal circulation and the air conditioning is on and the air intake volume is higher than the preset level, the air conditioning air intake mode will remain unchanged.

[0036] If the current air conditioning circulation mode is external circulation and the air conditioning is not turned on, the air conditioning intake mode will remain unchanged.

[0037] If the current air conditioning circulation mode is external circulation and the air conditioner is on with the air intake volume lower than the preset level, the air intake mode of the air conditioner will remain unchanged.

[0038] If the current air conditioning circulation mode is external circulation and the air conditioner is turned on with an air intake volume higher than the preset level, then the air intake mode will be switched to internal circulation.

[0039] The preset gear can be 2 gears, and its specific setting needs to be determined based on the vehicle's calibration results.

[0040] Preferably, when it is detected that all four doors of the vehicle are closed, the air conditioning circulation state is restored to the state before adjustment.

[0041] Because the air conditioning adjustment is a brief change in the circulation state in order to expel the air inside the car through the air conditioning vents, the air conditioning circulation state on the central control display remains unchanged from the time any one door of the vehicle is opened until all four doors are closed.

[0042] S103. If the vehicle is running and the doors, sunroof, and trunk are all closed, the windows are open and the total window height has not reached the predetermined value, the total window height will be adjusted if the vehicle door closing speed exceeds the predetermined value or the air intake volume is higher than the predetermined level when the air conditioning is in external circulation mode.

[0043] When the doors, sunroof, and trunk are all closed, and the total window height has not reached the predetermined value, if the door is detected to be open, and the closing speed of the door exceeds the predetermined value or the air intake of the air conditioner is higher than the predetermined level when the air conditioner is in external circulation mode, then the total window height needs to be adjusted.

[0044] The total lowering height of the vehicle windows refers to the sum of the lowering heights of the four vehicle windows. The lowering height of each window can be obtained through the window control module.

[0045] For example, if the total lowering amount h of the four doors is less than 40mm (this lowering value needs to be determined according to the different vehicles), the vehicle door closing speed exceeds 1.3m / s, and the air conditioning intake volume is higher than level 4 when the external circulation is on, then the window height needs to be adjusted.

[0046] The predetermined gear is a calibrated value. Different air intake gears of the air conditioner correspond to different air intake volumes. When the air intake volume is higher than a certain gear (such as gear 4) when the air conditioner is in external circulation mode, it is necessary to control the windows to lower to expel the internal air.

[0047] In some embodiments, the total lowering height of the vehicle window can be determined according to the formula: h = ((40 + (V - 1.3) * 10) - h 当前 (mm, v) represents the door closing speed. The constants in this formula need to be calibrated according to different vehicles.

[0048] This involves adjusting the height of the doors and windows that are closing or lowering all four doors to the same height; once all four doors are closed, the windows are restored to their original height or closed completely.

[0049] The window height adjustment is designed to prevent the force of the door closing into the vehicle when there is a strong closing force or a large air intake from the air conditioner. Once all four windows are completely closed, the windows should be returned to their original position or completely closed.

[0050] It should be understood that when the car window is already open to a certain extent, that is, when the total lowering height of the car window has reached the predetermined value, the air squeezed in by the closed door can be completely discharged through the car window, and there is no need to adjust the air conditioning or the car window glass.

[0051] In this embodiment, by adjusting the air conditioning circulation or the windows when the car door is closed, the problem of excessive closing force and ear pressure caused by air compression when closing the door can be avoided, effectively reducing the closing force and ear pressure. For situations with high door closing speed and high air conditioning intake, the car window glass can be adjusted in a timely manner.

[0052] In some embodiments, if the vehicle is in the started state and the doors, windows, sunroof, and trunk are all closed, when it is detected that the vehicle door closing speed exceeds a predetermined value or the air intake volume is higher than a predetermined level when the air conditioning is in external circulation mode, the total lowering height of the windows is adjusted.

[0053] When the car windows are completely closed, if the closing speed exceeds the preset value or the air intake volume is higher than the preset level when the air conditioner is in external circulation mode, the height of the car windows can also be adjusted directly.

[0054] In one embodiment, such as Figure 2 As shown, after obtaining the vehicle start-stop status in step S201, if the vehicle is in a turned-off state, and a door closing signal is detected in step S202, the air conditioning recirculation damper is controlled to switch to external circulation state, and the foot air vent is opened.

[0055] When the vehicle is turned off from the starting state or the power is switched off, the air conditioning automatically turns off. At the same time, the air conditioning recirculation damper needs to automatically switch to the external circulation state, and the foot vent opens. At this time, the interior space of the vehicle is connected to the outside through the air conditioning vents, air ducts, dampers, air conditioning unit, and external circulation damper. When the car door is closed, the air inside the vehicle can be exhausted to the outside through this channel, thereby reducing the closing force when closing the door and the ear pressure of the passengers inside the vehicle.

[0056] In one embodiment, if no passengers are detected in the rear seats of the vehicle, the air conditioning adjustment and window height adjustment are not activated.

[0057] Generally, the ear pressure in the rear seats is highest when the front doors are closed, which is most likely to cause dissatisfaction, while the ear pressure in the front seats is less likely to cause complaints when the rear doors are closed. When a vehicle is equipped with an in-vehicle life detection system, it determines whether there are vital signs of passengers inside the vehicle. Because the ear pressure of rear passengers is significantly higher when the front doors are closed than in other situations, the air conditioning and window adjustments can be left undone when no rear passengers are detected. When rear passengers are detected, the air conditioning or door / window adjustments can be made according to S102 and S103 mentioned above.

[0058] In some embodiments, when the life detection system detects a child inside the vehicle, it can also force the window to be lowered when one of the four doors is opened, in order to prevent damage to the child's eardrums caused by a large closing speed such as slamming the door.

[0059] In one embodiment, when the current weather is obtained through the vehicle's infotainment system, if it is currently raining, the height of the window glass of the opened vehicle door is adjusted.

[0060] To prevent rainwater from entering the vehicle through the four windows during rain, the windows should only be lowered through the open doors under the vehicle's door closing control system to minimize the impact on other passengers.

[0061] The vehicle's infotainment system can connect to the internet to check the current weather conditions to determine if it is raining, or it can use a rain sensor to detect whether it is raining. If it is raining, it can be set to adjust the windows only on the opened doors.

[0062] In some embodiments, the vehicle door closing optimization control function can be enabled or disabled, such as by adding a button or setting a virtual function button in the vehicle system. When this function is enabled, it can solve problems such as changes in ear pressure and increased closing force caused by closing the vehicle door. Since this function consumes some power and occupies some processor and memory resources, this function can also be disabled.

[0063] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0064] Figure 3 A schematic diagram of a vehicle door closing optimization control system provided in an embodiment of the present invention includes:

[0065] The status acquisition module 310 acquires the vehicle's start / stop status and the opening / closing status of the doors, windows, sunroof, and trunk.

[0066] The air conditioning adjustment module 320 is used to adjust the air conditioning intake mode according to the air conditioning circulation status and air intake volume when the vehicle is running and the doors, windows, sunroof and trunk are closed, and the system detects that any door of the vehicle is opened.

[0067] Specifically, adjusting the air conditioning intake mode based on the air conditioning circulation status and air intake volume includes:

[0068] If the current air conditioning circulation mode is internal circulation and the air conditioning is not turned on, switch the air conditioning intake mode to external circulation and open the foot vent.

[0069] If the current air conditioning circulation mode is internal circulation and the air conditioner is on with the air intake volume lower than the preset level, then switch the air intake mode of the air conditioner to external circulation.

[0070] If the current air conditioning circulation mode is internal circulation and the air conditioning is on and the air intake volume is higher than the preset level, the air conditioning air intake mode will remain unchanged.

[0071] If the current air conditioning circulation mode is external circulation and the air conditioning is not turned on, the air conditioning intake mode will remain unchanged.

[0072] If the current air conditioning circulation mode is external circulation and the air conditioner is on with the air intake volume lower than the preset level, the air intake mode of the air conditioner will remain unchanged.

[0073] If the current air conditioning circulation mode is external circulation and the air conditioner is turned on with an air intake volume higher than the preset level, then the air intake mode will be switched to internal circulation.

[0074] The adjustment of the air conditioning intake mode based on the air conditioning circulation status and air intake volume includes:

[0075] Once it is detected that all four doors of the vehicle are closed, the air conditioning recirculation mode is restored to the state before adjustment.

[0076] Because the air conditioning adjustment is a brief change in the circulation state in order to expel the air inside the car through the air conditioning vents, the air conditioning circulation state on the central control display remains unchanged from the time any one door of the vehicle is opened until all four doors are closed, and the air conditioning circulation needs to be restored to the state before the adjustment.

[0077] The window adjustment module 330 is used to adjust the total lowering height of the window glass if the vehicle is running and the doors, sunroof, and trunk are all closed, the windows are open and the total lowering height of the windows has not reached the predetermined value, and if it is detected that the closing speed of the vehicle doors exceeds the predetermined value or the air intake volume of the air conditioner is higher than the predetermined level when the external air circulation is activated.

[0078] For example, if the total lowering amount h of the four doors is less than 40mm (this lowering value needs to be determined according to the different vehicles), the vehicle door closing speed exceeds 1.3m / s, and the air intake volume is higher than level 4 when the air conditioner is in external circulation mode, then the window height needs to be adjusted.

[0079] The predetermined gear is a calibrated value. Different air intake gears of the air conditioner correspond to different air intake volumes. When the air intake volume is higher than a certain gear (such as gear 4) when the air conditioner is in external circulation mode, it is necessary to control the windows to lower to expel the internal air.

[0080] In some embodiments, the total lowering height of the vehicle window can be determined according to the formula: h = ((40 + (V - 1.3) * 10) - h 当前 (mm, v) represents the door closing speed. The constants in this formula need to be calibrated according to different vehicles.

[0081] When the status acquisition module 310 acquires the vehicle start / stop status and the opening / closing status of the doors, windows, sunroof, and trunk, it will select to adjust the air conditioning or windows when the door is detected to be open while the vehicle is running, based on the acquired air conditioning circulation status, air volume (indicated by gear), door closing speed, and current total window lowering height.

[0082] In one embodiment, if the vehicle is off, when a door closing signal is detected, the air conditioning recirculation damper is switched to external circulation mode and the foot air vent is opened.

[0083] The adjustment of the total lowering height of the vehicle window glass includes:

[0084] Adjust the height of the doors and windows that are closing, or lower all four doors to the same height.

[0085] After all four doors are closed, restore the vehicle windows to their original height or close them completely.

[0086] In one embodiment, the window adjustment module 230 includes

[0087] If no passengers are detected in the rear seats, the air conditioning and window height adjustments will not be activated.

[0088] In one embodiment, the window adjustment module 230 includes:

[0089] When the current weather is obtained through the vehicle's infotainment system, if it is raining, the height of the window glass of the opened door will be adjusted.

[0090] When it rains, rainwater may enter the vehicle through all four windows, so it's necessary to reduce the number of windows open. In this embodiment, when the vehicle doors are closed, only the windows of the opened doors are lowered, minimizing the impact on other passengers. The vehicle's infotainment system can connect to the internet to check the current weather conditions to determine if it's raining, or it can use a rain sensor to detect whether it's raining. If it is raining, it can be set to adjust the windows only for the opened doors.

[0091] It should be understood that the system can read vehicle status data based on the vehicle's CAN bus, such as vehicle start / stop, door closing, air conditioning circulation mode, air intake volume, door closing speed, and window lowering height, and generate corresponding command control signals to control the air conditioning circulation status or window raising and lowering without the need for additional hardware.

[0092] Those skilled in the art will understand that all or part of the steps in the methods of the above embodiments can be implemented by a program instructing related hardware. The program can be stored in a computer-readable storage medium. When the program is executed, it implements part or all of the processes in steps S101 to S104. The storage medium includes, for example, ROM / RAM.
