Technical Field

[0001] This invention relates to the field of vehicles, and in particular to a method for preventing the freezing of a concealed door handle, a freezing control device, and a vehicle. Background Technology

[0002] With the development of automotive technology, more and more newly developed high-end models are adopting hidden door handles. Hidden door handles have a strong sense of technology and aesthetics, while also reducing wind resistance and noise. The hidden door handle pops out when the door is opened and retracts when the car is in motion, making the car body surface smoother, the overall lines more fluid, and the drag coefficient lower.

[0003] In cold, rainy, or snowy weather, if the ambient temperature drops below freezing, the gap between the concealed door handles and the door of a car parked outdoors may freeze due to residual moisture, causing the concealed door handles to freeze and the door to be frozen and unable to be opened in a timely and smooth manner. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an antifreeze method, an antifreeze control device, and a vehicle, which solves the problem that the hidden door handles of automobiles are easily frozen in rainy or snowy weather.

[0005] In a first aspect, this application provides a method for preventing the freezing of a concealed door handle, used in a vehicle, comprising:

[0006] The weather type at the vehicle is determined based on the environmental image information at the vehicle.

[0007] When the weather type is a preset target weather type, the environmental feature information of the vehicle is obtained;

[0008] When the environmental feature information triggers a preset environmental rule, the hidden door handle is controlled to pop out.

[0009] In one embodiment, the environmental feature information includes precipitation data and ambient temperature near the vehicle, risk information sent from the cloud, and obstacle information near the hidden door handle. The step of controlling the hidden door handle to pop out when the environmental feature information triggers a preset environmental rule specifically includes:

[0010] When the precipitation data exceeds the preset precipitation threshold, determine whether the ambient temperature exceeds the preset first temperature threshold, and send a weather query command to the cloud.

[0011] When the ambient temperature is lower than the first temperature threshold, or when risk information received from the cloud in response to the weather query command includes the risk of a sharp drop in temperature, it is determined whether there is a target obstacle within the preset safe range of the hidden door handle;

[0012] When the target obstacle is not present, the hidden door handle is popped out.

[0013] In one embodiment, after determining whether there is a target obstacle within the preset safe range of the concealed door handle when the ambient temperature is lower than the first temperature threshold, the method further includes:

[0014] When the target obstacle is not present, determine the duration of the target weather type;

[0015] When the duration exceeds the preset duration, the temperature change data within the preset duration is determined, and the temperature change trend and the minimum temperature value within the preset duration are determined based on the temperature change data.

[0016] When the temperature change trend is downward, or when the minimum temperature value is lower than the second temperature threshold, the hidden door handle is controlled to pop out.

[0017] In one embodiment, before determining the weather type of the vehicle based on the environmental image information at the vehicle end, the method further includes:

[0018] In response to an opening command sent from the user terminal to pop out the hidden door handle, it is determined whether there is a target obstacle within the preset safety range of the hidden door handle; when there is no target obstacle, the hidden door handle is controlled to pop out.

[0019] In one embodiment, after responding to an opening command sent by the user terminal via the cloud for popping out the concealed door handle, the method further includes:

[0020] The weather type, environmental characteristics, and the pop-up status of the hidden door handle are sent to the user terminal.

[0021] In one embodiment, it further includes:

[0022] When the target obstacle is present within the preset safety range of the concealed door handle, a warning message to alert the user to the target obstacle will be sent.

[0023] Secondly, this application provides a method for preventing the freezing of a concealed door handle, for use on the user end, including:

[0024] In response to the user's operation of popping out the hidden door handle, an opening command for popping out the hidden door handle is sent from the cloud to the vehicle.

[0025] The system receives the vehicle's response to the opening command, controlling the pop-up state of the hidden door handle, as well as the vehicle's weather type and environmental characteristics information.

[0026] Thirdly, this application provides a method for preventing the freezing of a concealed door handle, used in the cloud, comprising:

[0027] Receives an opening command from the user terminal to pop out the hidden door handle, and sends the opening command to the vehicle terminal;

[0028] The system receives the vehicle's response to the opening command, controls the pop-up state of the hidden door handle, and sends the vehicle's weather type and environmental characteristic information to the user terminal.

[0029] Fourthly, this application provides an anti-freeze control device for a concealed door handle, executed from the vehicle end, comprising:

[0030] A weather determination module is used to determine the weather type on the vehicle based on the environmental image information on the vehicle.

[0031] The environment acquisition module is used to acquire the environmental feature information of the vehicle when the weather type is a preset target weather type;

[0032] The pop-up module is used to control the hidden door handle to pop out when the environmental feature information triggers a preset environmental rule.

[0033] Fifthly, this application provides a vehicle, characterized in that it includes a processor and a memory; wherein the memory stores a computer program for being loaded by the processor and executing the antifreeze method for a concealed door handle as described in any one of the first, second, or third aspects.

[0034] In the antifreeze method, antifreeze control device, and vehicle of the concealed door handle in this embodiment, by preventing freezing before freezing, compared to the risk of failure when breaking ice and heating after freezing, the concealed door handle can be popped out before freezing, completely avoiding the failure scenario where the concealed handle is frozen inside and cannot pop out when the user needs to use the vehicle.

[0038] Figure 3 This is a schematic diagram of the antifreeze control device for the concealed door handle in this embodiment. Detailed Implementation

[0039] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. Based on the description of the present invention, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0044] Figure 1 This is a diagram of the communication network system architecture for implementing the anti-freezing method for concealed door handles in this embodiment, including the vehicle end, cloud end, and user end. The vehicle end is equipped with a Central Domain Controller (CDM), which is connected via a LIN bus to a Sunlight and Rainfall Sensor (RLSM), a Temperature Sensor (TSM), a Front-View Camera (FLC), and a B-Pillar Camera (BLC). Specifically: the Sunlight and Rainfall Sensor (RLSM) is mounted on a bracket where the rearview mirror fits against the windshield; it measures rainfall near the vehicle by sensing imbalances in reflected light from the windshield near the RLSM. The Temperature Sensor (TSM) is typically mounted on a bracket on the front bumper and measures the ambient temperature near the vehicle using a thermistor. The Front-View Camera (FLC) is typically mounted below or on the front license plate holder and monitors the environment in front of the vehicle. The B-Pillar Camera (BLC) is typically mounted on the B-pillar and is used to identify obstacles near the concealed door handle. The Central Domain Controller (CDM) is also connected via a CAN bus to the driver's side door module (DDM), passenger side door module (PDM), left rear door module (RLDM), and right rear door module (RRDM). These modules are connected via a LIN bus to the left front door hidden handle (FL HANDLE), right front door hidden handle (FR HANDLE), left rear door hidden handle (RL HANDLE), and right rear door hidden handle (RR HANDLE), respectively. Each door module can control the opening of its corresponding hidden door handle. Furthermore, the CDM is also connected via a CAN bus to the Vehicle-to-Everything (TCAM) smart antenna module. The TCAM can wirelessly connect to the cloud and transmit data between the cloud and the user terminal. The user terminal can be a mobile device such as a smartphone or smartwatch with an app installed, or an electronic car key used to unlock the doors.

[0045] like Figure 2 As shown, this embodiment provides a method for preventing the freezing of a concealed door handle, used in a vehicle, including:

[0046] Step S100: Determine the weather type of the vehicle based on the environmental image information at the vehicle end;

[0047] Step S200: When the weather type is a preset target weather type, obtain the environmental feature information of the vehicle.

[0048] Step S300: When the environmental feature information triggers a preset environmental rule, control the hidden door handle to pop out.

[0049] In step S100, the Central Domain Controller (CDM) is equipped with a machine learning model capable of recognizing weather. By training the machine learning model, it can identify weather types such as sunny, rainy, foggy, and snowy weather. The CDM receives environmental image information sent from the forward-looking camera (FLC) and extracts feature points with significant weather characteristics from the environmental image information, such as white scene feature points in snowy weather and blurred scene feature points in foggy weather. By combining multiple feature points, the weather type in the environmental image information can be determined.

[0050] In step S200, the target weather type includes colder severe weather types such as rain, snow, freezing rain, hail or sleet. In these weather scenarios, the gap between the concealed door handle and the car door may condense into ice due to residual moisture, causing the concealed door handle to freeze.

[0051] The environmental feature information includes precipitation data and ambient temperature near the vehicle, risk information sent from the cloud, and obstacle information near the hidden door handle. In existing technology, the solar rain sensor (RLSM) typically works in conjunction with the lighting and wiper systems to automatically switch between high beams, low beams, fog lights, etc., and to control the activation and wiping speed of the wipers; the temperature sensor (TSM) is used for displaying the vehicle's overall temperature; and the B-pillar camera (BLC) is used for facial recognition to control the opening of the car's electronic door locks.

[0052] In step S300, to further determine whether the weather type at the vehicle end matches the detected target weather type, it is necessary to further obtain corresponding environmental feature information through the solar precipitation sensor RLSM, temperature sensor TSM, and B-pillar camera BLC. The solar precipitation sensor RLSM is used to obtain precipitation data near the vehicle end, the temperature sensor TSM is used to obtain the ambient temperature near the vehicle end, and the B-pillar camera BLC is used to determine whether there are target obstacles within the preset safety range of the hidden door handle.

[0053] When the environmental feature information triggers a preset environmental rule, controlling the hidden door handle to pop out specifically includes:

[0054] When the precipitation data exceeds the preset precipitation threshold, determine whether the ambient temperature exceeds the preset first temperature threshold, and send a weather query command to the cloud.

[0055] When the ambient temperature is lower than the first temperature threshold, or when risk information received from the cloud in response to the weather query command includes the risk of a sharp drop in temperature, it is determined whether there is a target obstacle within the preset safe range of the hidden door handle;

[0056] When the target obstacle is not present, the hidden door handle is popped out.

[0057] The precipitation data includes rainfall, snowfall, and hail. The precipitation threshold is 0.5 mm, which can be adaptively adjusted according to temperature changes. For example, when the temperature is -3 to 0℃, the precipitation threshold is 0.5 mm, while when the temperature is -5 to -3℃, the precipitation threshold is 0.3 mm.

[0058] When the precipitation data exceeds the preset precipitation threshold, it indicates that there is a risk of excessive water accumulation in the gap between the hidden door handle and the car door. At this time, it is necessary to further determine whether the hidden door handle is prone to freezing in a short period of time. Therefore, it is necessary to further determine the temperature near the vehicle and determine the risk information through the network to the cloud. When the temperature is too low or the weather forecast indicates a risk of a sharp drop in temperature in the near future, it has been determined that the hidden door handle is prone to freezing. Therefore, the next step of popping out the hidden door handle is required.

[0059] In this embodiment, the first temperature threshold is 5°C. When the temperature is greater than 5°C or there is no risk of a sharp drop in temperature within the next hour (or other time points), it indicates that although it is raining or snowing, the high temperature makes it difficult for the falling rain and snow to freeze, and the hidden door handle is unlikely to freeze. In this case, there is no need to pop out the hidden door handle. When the temperature is less than or equal to 5°C or there is a risk of a sharp drop in temperature within the next hour, the falling rain or snow is likely to freeze in the gap between the hidden door handle and the car door, causing the hidden door handle to freeze. In this case, the hidden door handle needs to be popped out in advance. The risk of a sharp drop in temperature refers to the risk information when the temperature drops by more than 10°C or more in a short period of time, and the lowest temperature drop reaches 5°C. It is understood that the precipitation threshold, the first temperature threshold, and the forecast time points in this embodiment can be adjusted according to geographical location and user needs.

[0060] Before popping out the concealed door handle, to avoid the risk of it colliding with obstacles such as other nearby vehicles, walls, or trees, the concealed door handle should only be popped out when there are no target obstacles nearby.

[0061] Due to the unpredictable nature of the weather, temperatures may still rise after rain or snow, meaning that concealed door handles may not be fully frozen for a short period. As the weather improves, the ice hidden inside the handles may melt. Since there is a significant risk of collision with other objects if a concealed door handle pops out, it's best to avoid popping it out whenever possible. Therefore, rainfall and temperature data need to be reconfirmed to ensure the necessary activation of the concealed door handle before doing so.

[0062] After determining whether there is a target obstacle within the preset safety range of the concealed door handle when the ambient temperature is lower than the first temperature threshold, the method further includes:

[0063] When the target obstacle is not present, determine the duration of the target weather type;

[0064] When the duration exceeds the preset duration, the temperature change data within the preset duration is determined, and the temperature change trend and the minimum temperature value within the preset duration are determined based on the temperature change data.

[0065] When the temperature change trend is downward, or when the minimum temperature value is lower than the second temperature threshold, the hidden door handle is controlled to pop out.

[0066] The duration refers to the total duration of monitoring the target weather type, such as rain or snow, and is not limited to a single type. In this embodiment, the duration is 5 minutes, and the second temperature threshold is 0°C. When the total duration of rain or snow monitored by the front-view camera FLC is more than 5 minutes, the temperature change data within 5 minutes needs to be monitored. The ambient temperature is periodically acquired by the temperature sensor TSM (e.g., measured every 30 seconds) to determine whether the temperature change within 5 minutes is an upward trend, a downward trend, or remains stable. When the temperature shows a downward trend, or the minimum temperature value is below 0°C, the driver's side door module DDM, passenger side door module PDM, left rear door module RLDM, and right rear door module RRDM control the driver's side door module DDM, passenger side door module PDM, left rear door module RLDM, and right rear door module RRDM to respectively drive the left front door hidden handle FL HANDLE, right front door hidden handle FR HANDLE, left rear door hidden handle RL HANDLE, and right rear door hidden handle RR HANDLE to pop out. When the ambient temperature is rising, it is necessary to determine whether the temperature at the end of the 5-minute period is higher than the first temperature threshold of 5°C. When the temperature is lower than 5°C, it indicates that the danger has not yet been eliminated, and the forward-looking camera FLC still needs to monitor whether the weather type has changed until the weather type is no longer the target weather type. When the temperature is higher than 5°C, it indicates that the danger has been eliminated, and it is no longer necessary to continue monitoring the weather type and environmental characteristics.

[0067] In some scenarios, users can obtain weather changes in advance based on the vehicle's location via weather forecasts or alert text messages, allowing them to open the hidden door handles in advance. When the user is in a different location than the vehicle, or if the user does not wish to manually open the hidden door handles, they can do so via a mobile device with the user-side app installed.

[0068] Before determining the weather type of the vehicle based on the environmental image information of the vehicle, the method further includes: in response to an opening command sent from the user terminal for popping out the hidden door handle, determining whether there is a target obstacle within a preset safe range of the hidden door handle; when there is no target obstacle, controlling the hidden door handle to pop out.

[0069] The user-side app features a virtual (or physical) button for opening the concealed door handles. Users can click the virtual button to send an opening command via the cloud to the vehicle, causing the vehicle's Central Domain Controller (CDM) to pop out the four concealed door handles. Additionally, the user-side app can be linked to a weather forecast system, storing the vehicle's location information within the forecast. When the forecast for the vehicle's location matches the target weather type, the user-side app automatically initiates communication with the cloud, sending an opening command to the vehicle via the cloud server.

[0070] After responding to the user's command sent via the cloud to pop out the hidden door handle, the method further includes: sending the weather type, the environmental feature information, and the pop-out status of the hidden door handle to the user.

[0071] When the hidden door handles are opened, the vehicle will send the user's mobile app via SMS the current weather type, ambient temperature, duration of snowfall, and the status information of each hidden door handle. For example, in a snowy day with a temperature of -3°C, after opening the door handles, the user's mobile app will receive a notification message stating, "The current ambient temperature is -3°C, snowfall has been ongoing for 6 minutes. To avoid the risk of freezing, the hidden handles of the left front door, left rear door, right front door, and right rear door have been opened for you."

[0072] In one embodiment, the method further includes: when the target obstacle exists within the preset safety range of the concealed door handle, sending a warning message to the user terminal to alert the user to the target obstacle.

[0073] The safe range of concealed door handles is typically set based on their pop-out length. When an obstacle exists within this safe range, the B-pillar camera (BLC) determines the obstacle's distance, structure, shape, and other attributes, and uses this information to assess whether it might obstruct the door handle's pop-out. By sending a warning to the user, the system can remind them to adjust the vehicle's parking position so that the Central Domain Controller (CDM) can automatically control the pop-out of all four concealed door handles. For example, if another vehicle is nearby on the right side of the vehicle, creating an obstacle, only the left front door handle (FL HANDLE) and left rear door handle (RL HANDLE) can be activated. The user's mobile app will receive a message stating, "Due to an obstacle on the right side of the vehicle, the right front and right rear door handles are temporarily unable to pop out. Please remove the obstacle and try again."

[0074] The retractable door handle in this embodiment remains in the pop-up state until the owner unlocks the vehicle again, drives, or locks it again, at which point the retractable door handle will retract normally. It is understood that the retractable door handle in this embodiment can also automatically retract when the weather type at the vehicle end is not the target weather type such as rain or snow, or when the temperature is high.

[0075] In summary, the anti-freezing method for the concealed door handle in this embodiment has several advantages. First, by preventing freezing before it occurs, compared to the risk of failure from de-icing and heating after freezing, the concealed door handle can be popped out before freezing, completely avoiding the scenario where the concealed handle is frozen inside and cannot pop out when the user needs to use the vehicle. Second, the sunlight and rain sensor RLSM, temperature sensor TSM, B-pillar camera BLC, and the control modules for the four concealed door handles are all essential hardware in existing vehicles, eliminating the need for new hardware structures and effectively controlling costs. Third, the vehicle can automatically determine whether the concealed handle needs to pop out and initialize it when the user unlocks the vehicle again, eliminating the need for the user to perform additional opening or closing operations, reducing the user's learning curve and preventing user errors. Fourth, this invention can also interconnect the vehicle status with the cloud and the user's mobile app, allowing the handle to pop out remotely via the app when the user needs it, and also sending a reminder to the user's mobile app when the concealed door handle pops out even without user operation but environmental conditions triggering the function, avoiding user confusion. Fifthly, by calling up various sensors and repeatedly confirming them, we avoid accidental triggering caused by misjudging the environment, and also avoid vehicle damage and property loss caused by rashly popping out the hidden door handle without confirming the environment.

[0079] The pop-up module M30 is used to control the hidden door handle to pop out when the environmental feature information triggers a preset environmental rule.

[0080] This invention provides yet another method for preventing the freezing of concealed door handles, for use on the user end, including:
