Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted control technology, and in particular to a vehicle sealing strip control method, device and equipment. Background Art

[0002] A car's sealing system is crucial for keeping out rain, dust, and noise, and maintaining a stable cabin temperature. It includes components such as the hood seal, door frame seals, door seals, auxiliary door seals, glass run channels, internal and external watertight seals, sunroof seals, and auxiliary front and rear windshield seals. Door and frame seals play a key role in ensuring sealing, waterproofness, and airtightness during door opening and closing. However, traditional sealing strip designs can typically only optimize a specific aspect of performance by adjusting the sealing reaction force. For example, improving sealing performance requires increasing the sealing force, while reducing the door closing force requires decreasing the sealing force. This single-minded design makes it difficult to simultaneously meet diverse usage needs. With increasing consumer demand for automotive quality and the increasing incidence of extreme weather events, existing sealing solutions are no longer adequately addressing these challenges.

[0003] Existing solutions primarily utilize pneumatic processes to control expansion and contraction, employing engineered rubber elastomer formulations and modern manufacturing techniques to meet the requirements of numerous applications. These intelligent control methods provide a superior seal, improved closing sound quality, and enhanced passenger comfort.

[0004] Existing sealing strip control methods only consider a single scenario and fail to consider situations where the vehicle is wading through water deeper than 600mm. They also fail to address how to use inflatable sealing strips to further improve NVH (noise, vibration, and harshness) performance and reduce ear pressure. Furthermore, under high-speed driving conditions, there is no detailed explanation of how to use inflatable sealing strips to reduce the pressure difference between the inside and outside of the vehicle, thereby reducing the noise level inside the vehicle to ensure a comfortable driver experience. In low-temperature conditions, especially when parking outdoors in winter, the sealing strips may be compressed and frozen due to the cold, making it difficult to open the door. There is no coverage of how to use the inflation function to heat the sealing strips to facilitate unlocking the door. Therefore, there is an urgent need for a more accurate and diverse vehicle sealing strip control method to improve vehicle safety. Summary of the Invention

[0005] The main purpose of this application is to provide a vehicle sealing strip control method, device and equipment, aiming to solve the technical problem of how to adopt a correct sealing strip control strategy to adapt to different working conditions.

[0042] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0043] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The main solution of the embodiment of the present application is: obtaining vehicle operation information, obtaining target operating conditions based on the vehicle operation information, and executing the sealing strip control strategy to control the sealing strip according to the target operating conditions.

[0045] Based on this, the embodiment of the present application provides a vehicle sealing strip control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle sealing strip control method of the present application.

[0046] In this embodiment, the vehicle sealing strip control method includes steps S10 to S30:

[0047] Step S10: Acquire vehicle operation information.

[0048] It's important to note that acquiring vehicle operating information is a key step in achieving intelligent control of the inflatable seal. Using a variety of sensors installed on the vehicle, such as speed sensors, acceleration sensors, temperature sensors, and water pressure sensors, the system monitors and collects dynamic vehicle data in real time. Vehicle status sensors monitor information such as door closure status, vehicle speed, internal and external temperature differences, and internal pressure to determine the vehicle's current operating conditions. These sensors then send commands to the gas tank connected to the seal, enabling precise control of the inflatable seal.

[0049] Step S20: obtaining a target operating condition based on vehicle operating information, where the vehicle operating information includes at least one of a door closing state, a vehicle speed, an interior temperature, an exterior temperature, and an interior pressure.

[0050] It should be noted that by monitoring key parameters such as the door closing status, vehicle speed, interior temperature, exterior temperature and interior pressure, the vehicle's multiple operating conditions can be accurately identified, thereby precisely controlling the vehicle's various systems.

[0051] Specifically, when a door begins to close, the system detects the door closing motion through the door lock sensor and determines it as closed driving. The vehicle's speed sensor monitors the current driving speed. When the speed exceeds 110 km / h or a user-defined speed value, it is identified as high-speed driving. Temperature sensors are installed inside and outside the vehicle to monitor ambient temperature changes. If the interior temperature drops below -10°C or the exterior temperature reaches a set low-temperature threshold, it is identified as low-temperature driving. Water pressure sensors installed on the doors can measure the external water level. If the vehicle is in a flooded area (the sensor height is set between 400 and 800 mm above the ground) and the water pressure reaches a predetermined level, it indicates a risk of flooding and is identified as flooded driving. When the vehicle receives a Bluetooth key unlock signal or other information indicating that the vehicle is about to be used, it is identified as vehicle readiness.

[0052] Step S30 , executing a sealing strip control strategy to control the sealing strip according to the target operating condition, where the sealing strip control strategy is used to adjust the pressure or temperature inside the vehicle.

[0053] It should be noted that according to the vehicle's multiple operating conditions, the system will execute corresponding inflatable sealing strip control strategies to optimize the vehicle's safety, comfort and waterproof performance.

[0054] Furthermore, step S30 also includes sending a first control instruction to the gas tank when the target operating condition is closed driving, so that the gas tank performs an exhaust operation on the door sealing strip until the pressure in the car reaches a preset safety threshold. Specifically, when the door begins to close, the vehicle's BCM (body control module) will monitor the door closing action and send an instruction to the gas tank designed at the sealing strip interface to start the exhaust process and quickly reduce the reaction force of the sealing strip to less than 80N for a single door. At the same time, the BCM adjusts the door lock suction force to about 100N, so that the door can be sucked into a semi-locked state. Even if fingers or other parts of the body are pinched, no serious injury will be caused. Once the full lock signal is transmitted to the BCM, the system will inflate the sealing strip through the air supply of the air conditioner to restore and enhance its sealing function to ensure good sound insulation and waterproof effects.

[0055] Furthermore, step S30 also includes, when the target operating condition is flooded driving, sending a second control command to the gas tank to inflate the bubble tube of the sealing strip and activating the ventilation device to increase air circulation inside the vehicle. Specifically, in extreme weather conditions, such as flooding caused by heavy rain, the water pressure sensor on the vehicle door (set at a height of 400-800mm) will detect the external water pressure value. When the preset threshold is reached, it indicates that the vehicle is at risk of flooding. At this time, the BCM sends a command to the gas tank to supply air to expand the sealing strip and activate the ventilation device to increase air circulation inside the vehicle, increase the contact area with the door sheet metal, improve sealing performance, and prevent moisture from entering the vehicle. In addition, the BCM can also activate the interior ambient light as a warning to alert the driver to the current environmental conditions. When the operating condition switches from flooded driving to normal driving, a first control command is sent to the gas tank to depressurize the sealing strip until the internal pressure reaches a preset safety threshold. This operation is intended to gradually reduce the reaction force of the sealing strip, allowing the pressure inside and outside the vehicle to gradually reach a balanced state. During the air extraction process, the vehicle's BCM (body control module) will continuously monitor the data from the pressure sensor inside the vehicle to ensure that the pressure inside the vehicle drops steadily and eventually reaches the preset safety threshold.

[0056] Furthermore, step S30 also includes sending a second control command to the gas tank to inflate the bubble tube of the sealing strip and activate the air outlet device to increase air circulation within the vehicle when the target operating condition is high-speed driving. Specifically, when the vehicle speed sensor detects a speed exceeding 110 km / h or a user-set speed threshold, the BCM identifies high-speed driving as occurring. In this case, the system also inflates the sealing strip from the gas tank to strengthen its seal, reduce wind noise caused by the internal and external pressure differential, and improve driving comfort.

[0057] Furthermore, step S30 also includes sending a third control instruction to the gas tank when the target operating condition is low-temperature driving, so that the gas tank uses the flow of the engine's antifreeze coolant to heat the high-temperature water tank through the high-temperature solution, and then uses the blower to blow the low-temperature air through the high-temperature water tank to obtain warm air, and then sends warm air to the bubble tube of the sealing strip to increase the temperature inside the car. Specifically, when the temperature sensor detects that the temperature inside or outside the car is lower than -10°C, or receives a Bluetooth key unlocking signal, it indicates that the sealing strip may need to be heated in advance to avoid freezing. The system can remotely start the air conditioning heater through the mobile phone APP, and send heat to the sealing strip through the gas tank to accelerate the melting of ice and ensure smooth unlocking even in cold weather. If the temperature inside the car drops to -5°C, the system will also automatically start this heating process to ensure smooth door opening.

[0058] Furthermore, step S30 also includes, when the target operating condition is the vehicle ready state, sending a first control command to the gas tank to deflat the gas tank until the vehicle interior pressure reaches a preset safety threshold. Specifically, when the BCM receives the unlock command, the gas tank will deflate, reducing the reaction force of the sealing strip, making door opening easier and reducing the popping sound, thereby improving the sound quality of the door opening and closing. When the operating condition changes from the vehicle ready state to normal driving, the gas tank deflating or filling operation is automatically adjusted based on the vehicle state to adapt to different operating conditions. When the vehicle switches from the ready state to normal driving, the system automatically adjusts the gas tank deflating or filling operation based on the vehicle state to adapt to different operating conditions. In the ready state, if the door has just been closed or the vehicle is stationary, the sealing strip may already be inflated to ensure a good seal and prevent external dust and moisture from entering the vehicle interior. Once the vehicle is detected to be started and entering normal driving mode, the vehicle's BCM (body control module) determines whether the sealing strip status needs to be adjusted based on the speed sensor, temperature sensor, and possibly other environmental parameters. For example, when the vehicle begins moving and gradually increases in speed, the system may appropriately evacuate the sealing strips to reduce their reaction force, thereby reducing wind noise and improving the pressure balance inside and outside the vehicle, enhancing passenger comfort. Conversely, when starting the vehicle in a low-temperature environment, if the system detects that the sealing strips have hardened due to the cold, it will first preheat the sealing strips through the air conditioning heating function and then appropriately inflate them to ensure that the door can be opened smoothly and maintain good sealing performance. Throughout this process, the system's intelligent control logic ensures that the sealing strips can be flexibly adjusted according to different driving conditions, not only improving the safety and waterproof performance of the vehicle, but also enhancing the overall driver and passenger experience. This adaptive adjustment mechanism enables the vehicle to maintain optimal sealing in a variety of complex environments, thereby better coping with the challenges of different road conditions.

[0059] This embodiment provides a vehicle sealing strip control method. By acquiring vehicle operating information, a target operating condition is determined based on the vehicle operating information, and a sealing strip control strategy is implemented to control the sealing strip according to the target operating condition. The state of the inflatable sealing strip is adjusted based on the vehicle operating information to achieve anti-pinch and waterproofing, as well as improve vehicle interior temperature and comfort.

[0060] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 2 The vehicle sealing strip control method step S20 further includes steps S201 to S205:

[0061] Step S201: When the door is closed, it is determined that the target operating condition is closed driving.

[0062] It should be noted that when the door is closed, the system determines the operating condition as closed driving. In this state, the vehicle's BCM (body control module) will implement the appropriate sealing strip control strategy based on the specific door closing conditions. First, the BCM monitors the door closing process through the door lock sensor and the air tank at the sealing strip interface. As the door begins to close, the BCM sends a signal to the air tank to initiate the air pumping process, rapidly reducing the sealing strip's reaction force. This ensures that even if fingers or other body parts are trapped during the door closing process, serious injury will not occur. At this time, the door lock's closing force is also reduced accordingly, typically to approximately 100N, further reducing the risk of pinching. Once the door is fully closed and locked, the BCM sends a new command to the air tank, supplying air through the air conditioning system to inflate the sealing strip, thereby improving the seal's fit to the door sheet metal.

[0063] Step S202: When the pressure inside the vehicle exceeds a preset pressure threshold, it is determined that the target operating condition is flooded driving.

[0064] It's important to understand that when the vehicle's internal pressure exceeds a preset threshold, the system identifies the vehicle as being in flooded conditions. In this case, the vehicle may be traversing a flooded road or experiencing severe flooding caused by heavy rain. To address this situation, the vehicle's BCM immediately takes steps to enhance the vehicle's water resistance. First, the BCM receives data from a water pressure sensor, typically mounted at the bottom of the door at a height of 400 to 800 mm above the ground. These sensors monitor external water levels. Once the water pressure reaches the preset threshold, indicating a flood risk, the BCM sends a command to the air tank located at the sealing strip interface, initiating the inflation process. The air conditioning system then supplies air to the air tank, inflating the sealing strip, increasing the contact area and sealing force between the sealing strip and the door sheet metal.

[0065] Step S203: When the vehicle speed exceeds a preset speed threshold, it is determined that the target operating condition is high-speed driving.

[0066] It should be noted that when the vehicle speed exceeds a preset threshold (e.g., 110 km / h), the system determines that the vehicle is operating at high speed. In this case, the vehicle's BCM automatically adjusts the state of the inflatable seal to accommodate high-speed driving based on data from the vehicle's speed sensor. Specifically, the BCM sends a command to the air tank located at the seal's interface to initiate the inflation process. The air conditioning system supplies air to the tank, inflating the seal, thereby increasing the contact area and sealing force between the seal and the door sheet metal. This enhanced sealing performance effectively reduces wind noise at high speeds, improving cabin quietness and providing a quieter and more comfortable ride for drivers and passengers. Furthermore, this improved sealing improves interior airtightness and reduces the discomfort caused by external air flow, significantly enhancing vehicle stability and passenger comfort, especially when traveling through tunnels or encountering crosswinds. Furthermore, the system continuously monitors vehicle speed to ensure that the seal's state is always optimized for current driving conditions. If the vehicle speed drops below a preset threshold, the system will automatically switch back to normal and reduce the reaction force of the sealing strip through vacuum operation to maintain proper sealing effect while avoiding ear pressure discomfort or other problems that may be caused by excessive sealing.

[0067] In step S204 , when the temperature inside the vehicle is less than a first preset temperature threshold and the temperature outside the vehicle is less than a second preset temperature threshold, it is determined that the target operating condition is low-temperature driving, wherein the first preset temperature threshold is greater than the second preset temperature threshold.

[0068] It should be noted that when the interior temperature falls below a first preset threshold (e.g., -5°C) and the exterior temperature falls below a second preset threshold (e.g., -10°C), the system determines that the operating condition is low-temperature driving. In this case, the vehicle's body control module (BCM) initiates a series of actions to mitigate the effects of the low temperature on the vehicle. First, the BCM uses temperature sensors to monitor changes in interior and exterior temperatures. Once these temperatures fall below the set thresholds, the system takes immediate action. To prevent the sealing strip from compressing and freezing in cold conditions, making the door difficult to open, the system sends a command to the air tank located at the sealing strip interface to initiate heating and inflating. The air conditioning system supplies warm air to the air tank, heating and inflating the sealing strip. This not only accelerates the heating of the sealing strip, restoring its elasticity, but also strengthens the fit between the sealing strip and the door sheet metal, ensuring a good seal.

[0069] Furthermore, if the vehicle receives a Bluetooth key signal or the user remotely activates the heating function via a mobile app, the system also pre-activates the heating process to ensure the sealing strip is in optimal working condition before the user enters the vehicle. This pre-heating not only improves the convenience of door opening but also reduces the risk of sealing strip hardening caused by low temperatures, thereby extending the service life of the sealing strip.

[0070] Step S205 : When the vehicle unlocking instruction is received, it is determined that the target operating condition at this time is the vehicle ready state.

[0071] It's important to note that when the system receives the vehicle unlock command, it determines the current operating condition as vehicle readiness. In this case, the vehicle's BCM (body control module) initiates a series of pre-set actions to ensure the vehicle is in optimal condition before use. First, the BCM sends a command to the air tank located at the seal interface to initiate a degassing process, reducing the seal's reaction force. This reduces resistance when the door opens, making it easier to open, and reduces the door's popping sound, improving the sound quality of the door opening and closing.

[0072] This embodiment determines the operating condition as closed driving when the door is closed; determines the operating condition as flooded driving when the vehicle interior pressure exceeds a preset pressure threshold; determines the operating condition as high-speed driving when the vehicle speed exceeds a preset speed threshold; determines the operating condition as low-temperature driving when the interior temperature is less than a first preset temperature threshold and the exterior temperature is less than a second preset temperature threshold, where the first preset temperature threshold is greater than the second preset temperature threshold; and determines the operating condition as vehicle readiness when a vehicle unlock command is received. By determining the operating condition type, the sealing strip is intelligently controlled based on the operating condition type, the door status, the interior pressure, the vehicle speed, the temperature, and the unlock command.

[0073] This application also provides a vehicle sealing strip control device, please refer to Figure 3 , the device comprises:
