Description

Technical Field

[0001] This invention relates to the field of vehicle network control technology, specifically to a remote control method, device, equipment, and medium for preventing vehicle icing. Background Technology

[0002] With the rapid development of vehicle networking and intelligent connected vehicle technologies, the ability to remotely control vehicles in all scenarios and actively protect against extreme weather has become an important direction for improving the user experience and driving safety.

[0003] Existing vehicle de-icing solutions mostly involve local passive defrosting or glass heating after the vehicle is started, which is a reactive approach. For example, a temperature sensor detects the ambient temperature and activates the windshield wiper heating system, or the air conditioning is controlled to defrost and the wipers are intermittently activated after receiving a defrosting command. All of these solutions require manual activation by the driver or passive activation by the system after the vehicle is started, and cannot anticipate the risk of icing and implement proactive protection while the vehicle is parked.

[0048] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0049] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0050] New energy vehicle anti-icing control technology is mainly applied to vehicle parking and preparation scenarios in winter environments such as low temperatures, rain, snow, and frost, focusing on the problem of frost and ice formation on the windshield and wiper area. The relevant system typically consists of onboard sensors, defrosting and heating devices, wiper control mechanisms, and a remote terminal or cloud platform that communicates with the vehicle to sense environmental conditions and perform anti-icing or de-icing operations.

[0051] Current vehicle anti-icing mechanisms in low-temperature environments primarily rely on local detection of outside temperature, local humidity, or glass surface conditions. Once a preset threshold is reached, windshield heating, wiper defrosting, or anti-icing control are activated. Some solutions trigger processing through a single sensor signal, while others combine local images or frosting conditions for judgment. Overall, their operation is still mainly based on reactive processing after icing occurs.

[0052] These technical approaches are less adaptable to complex weather conditions. The actual icing situation on a vehicle is influenced by a combination of factors, including temperature changes, humidity, precipitation trends, duration of sustained low temperatures, and the local environment around the vehicle. Relying solely on local thresholds or local condition detection can easily lead to delayed warnings and inaccurate risk assessments. Activating the de-icing device after ice has already formed results in longer processing times, higher energy consumption, and the wipers operating in a frozen state may cause problems such as jamming, abnormal noises, or increased load.

[0053] These shortcomings directly impact the winter driving experience and control reliability. Users often only discover that the wiper area is frozen when they are about to use the vehicle, and then have to perform de-icing on the spot. This is not conducive to preparing the vehicle in advance, and it is also difficult to strike a balance between efficiency, energy consumption, and component protection.

[0054] Based on the aforementioned technical problems, this embodiment expands the assessment of vehicle icing risk from a single threshold detection to a joint analysis of weather forecast data and environmental parameters. It first obtains weather change information for the vehicle's location area, then combines this with the vehicle's environmental conditions to identify potential icing trends, thus enabling earlier anti-icing control. After determining the icing risk level, corresponding anti-icing control commands are output according to different risk levels, and corresponding antifreeze strategies are executed on the vehicle side, ensuring that the control process adjusts around changes in risk.

[0055] In this embodiment, a collaborative link is formed between the cloud platform, the vehicle-mounted sensing and acquisition module, the vehicle control module, and the user terminal. Meteorological information acquisition, risk assessment, command output, and strategy execution are interconnected, which improves the problems of delayed icing judgment and passive control response in low-temperature environments, and enhances the reliability and timeliness of vehicle anti-icing control.

[0056] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0057] Figure 1 This is a flowchart illustrating the vehicle anti-icing remote control method provided in an embodiment of this application. Figure 1 As shown, the method provided in this embodiment can be executed by a vehicle network cloud platform, a remote control platform, a vehicle controller, or a control system composed of a vehicle network cloud platform and a vehicle controller. Specifically, the method in this embodiment may include:

[0058] S101: Obtain meteorological forecast data and environmental parameters for the vehicle's location area.

[0059] Among them, meteorological forecast data is used to provide information on future weather changes in the vehicle's location area, serving as an important basis for judging the risk of icing; environmental parameters are used to reflect the real-time status of the vehicle's current environment, supplementing meteorological forecast data for risk assessment.

[0060] In practice, the vehicle first determines its current location via its onboard positioning module and uploads the location identifier to the vehicle-to-everything (V2X) cloud platform. Based on this, the V2X cloud platform initiates a data query request to the meteorological service platform to obtain weather forecast data for the located area within a preset time period. Simultaneously, the vehicle's environmental perception and acquisition module collects environmental parameters such as outside temperature and humidity, and vehicle body temperature in real time, sending them to the vehicle controller. These parameters are then uploaded to the V2X cloud platform via a remote communication module, or directly used in subsequent calculations on the vehicle. To ensure consistency in subsequent risk assessments, the acquired weather forecast data and environmental parameters are aligned using a unified timestamp, and outliers are filtered or removed.

[0061] In one possible implementation, weather forecast data can be acquired using a combination of periodic fetching and event-triggered updates; environmental parameters can be acquired through real-time sampling or periodic sampling. Based on the aforementioned data acquisition chain, vehicles can obtain combined data of future weather trends and current local conditions before icing forms, providing timely input for subsequent icing risk analysis.

[0062] S102: Determine the icing risk level of vehicles based on meteorological forecast data and environmental parameters.

[0063] Among them, the icing risk level is used to characterize the likelihood of vehicles icing and serves as the basis for subsequent output of anti-icing control commands and selection of antifreeze strategies. Specifically, it is implemented by integrating and analyzing meteorological forecast data and environmental parameters, and classifying the risk into different levels by comparing the results with preset judgment conditions.

[0064] In this embodiment, the vehicle controller or the vehicle network cloud platform processes the data acquired by S101 and, combined with future weather trends and the vehicle's current environmental status, determines the vehicle's icing risk level. For example, the risk level can be divided into four levels: no risk, low risk, medium risk, and high risk. In some other implementations, the risk level can also be divided according to actual needs; this embodiment does not specifically limit the method of risk level division.

[0065] To adapt risk assessment to different vehicle models and antifreeze capabilities, relevant assessment parameters can be written into a control parameter table based on test data during the vehicle calibration phase. The control parameter table can be stored in the vehicle network cloud platform or the vehicle's non-volatile memory and can be selected according to the vehicle model configuration.

[0066] In the specific processing, a multi-dimensional threshold joint judgment can be made based on the predicted ambient temperature, predicted dew point temperature, predicted snowfall probability, predicted duration of continuous low temperature and windshield surface temperature. The icing risk index is obtained by linear weighting, piecewise mapping or table lookup calculation. The icing risk index is then compared with the preset risk threshold to determine the icing risk level.

[0067] For example, based on meteorological forecast data, the predicted ambient temperature, predicted dew point temperature, predicted snowfall probability, and predicted duration of sustained low temperatures can be obtained; based on environmental parameters, the windshield surface temperature can be determined; based on the predicted ambient temperature, predicted dew point temperature, predicted snowfall probability, predicted duration of sustained low temperatures, and windshield surface temperature, the vehicle icing risk index can be determined; and based on the comparison result between the icing risk index and the preset risk threshold, the icing risk level can be determined.

[0068] In practical implementation, the remote control platform or vehicle-to-everything (V2X) cloud platform receives weather forecast data from the meteorological service platform and analyzes the temperature, dew point, snowfall probability, and duration of low temperatures for the corresponding time period in the vehicle's location area to generate predicted ambient temperature, predicted dew point temperature, predicted snowfall probability, and predicted duration of low temperatures. The vehicle-side environmental perception and acquisition module collects external temperature and humidity, vehicle body temperature, and environmental parameters related to the windshield's thermal coupling, and determines the windshield surface temperature based on the collected values ​​or a preset mapping relationship. Subsequently, the vehicle controller performs weighted fusion of these parameters.

[0069] The lower the predicted ambient temperature, the closer the predicted dew point temperature is to the ambient temperature, the higher the predicted probability of snowfall, the longer the predicted duration of sustained low temperatures, and the lower the windshield surface temperature, the greater the corresponding icing risk index. The vehicle controller then compares the icing risk index with a preset risk threshold and outputs an icing risk level of no risk, low risk, medium risk, or high risk.

[0070] In addition, a time window smoothing mechanism can be added, which upgrades the risk level when multiple consecutive calculation cycles point to a high risk, and lowers the risk level when multiple consecutive cycles point to a decrease, thereby reducing misjudgments caused by single data fluctuations.

[0071] Based on the above analysis, by incorporating future weather changes and the local real-time status of vehicles into the judgment, the single threshold trigger can be changed to trend risk identification, thus advancing the icing warning time and establishing a correspondence between the risk level and subsequent control strategies.

[0072] S103: Output the corresponding anti-icing control command according to the icing risk level.

[0073] In this step, the anti-icing control command is used to send a control signal to the vehicle to perform anti-icing operations after detecting an icing risk. Specifically, it is triggered by the risk level and matched with the vehicle's executable functions. After determining the icing risk level, the vehicle-to-everything (V2X) cloud platform or vehicle controller can generate the corresponding control content based on a preset level command mapping relationship.

[0074] In practice, if the icing risk level is low or medium, a warning message containing the icing risk level, warning content, and vehicle identification information is generated and sent to the user terminal via the vehicle-to-everything (V2X) communication link. The user terminal then displays a pop-up window, push notification, or status bar notification, informing the user that the vehicle may experience icing in the near future. If the icing risk level is high, an anti-icing control command can be directly generated and sent to the onboard execution unit to trigger windshield heating, wiper defrosting, or other anti-freezing strategies. Simultaneously, a status feedback message is generated and sent to the user terminal, containing a status field indicating that "anti-icing operation is enabled."

[0075] For example, anti-icing control commands and status feedback can be transmitted via the vehicle communication module through a mobile network or vehicle network channel. After the status feedback reaches the user terminal, the application displays the current vehicle status as performing anti-icing operation.

[0076] Therefore, the icing risk level is converted into a structured control command, which can support remote control and achieve automatic response in the corresponding scenario. Different risk levels correspond to different output content, realizing remote linkage control under risk classification.

[0077] S104: In response to the anti-icing control command, execute the corresponding anti-freezing strategy.

[0078] In this step, the antifreeze strategy is used to execute actual anti-icing actions after receiving the anti-icing control command, which is completed by the vehicle control system in conjunction with relevant actuators. In this embodiment, after receiving the anti-icing control command, the vehicle controller parses the command type and parameters, and sends an action command to the corresponding execution unit to execute the antifreeze strategy corresponding to the anti-icing control command.

[0079] Specifically, the anti-freezing strategy includes at least one of the following: vertical wiper mounting and heating / de-icing. Vertical wiper mounting refers to controlling the wiper drive mechanism to raise the wipers from their normal parking position to a vertically locked position, detaching the wiper blades from the windshield surface to prevent them from freezing and sticking to the glass under low-temperature conditions. Heating / de-icing involves activating the windshield heating module and the wiper heating module to heat the windshield surface and the wiper blade area, respectively, to melt existing frost or prevent frost from condensing. The vehicle controller can select and execute one or more combinations of these strategies based on different anti-icing control commands received.

[0080] During the execution of the antifreeze strategy, the environmental perception and acquisition module continuously collects environmental parameters. The control system monitors the execution process of the antifreeze strategy based on environmental changes and terminates the corresponding antifreeze strategy when preset termination conditions are met. To ensure execution reliability, the vehicle can check the relevant execution status before taking any action. When an abnormality is detected, the vehicle controller stops the corresponding action and sends feedback.

[0081] Based on the above analysis, it can be seen that the execution phase is not a fixed operation after a single trigger, but rather a closed-loop control process formed by combining real-time monitoring, from judging the icing risk level, issuing anti-icing control commands to executing antifreeze strategies and automatically exiting, so that the vehicle can implement forward-looking anti-icing control based on risk changes in low temperature, rain, snow or frost environments.

[0082] The vehicle anti-icing remote control method provided in this embodiment acquires weather forecast data and environmental parameters of the vehicle's location area, determines the vehicle's icing risk level based on the weather forecast data and environmental parameters, outputs corresponding anti-icing control commands according to the icing risk level, and executes corresponding antifreeze strategies in response to the anti-icing control commands. Thus, the icing risk input is first formed by the weather trend information of the vehicle's location area and the real-time local environmental information of the vehicle. Then, differentiated control criteria are formed through risk level classification. Subsequently, corresponding commands are sent to the vehicle to drive the execution of corresponding antifreeze strategies. Simultaneously, environmental parameters are continuously monitored during execution, and the antifreeze strategy is automatically adjusted or terminated based on changes in risk. Therefore, icing judgment is transformed from a reactive triggering after icing to a predictive control before icing, shifting the control timing forward and matching the control action with the icing risk level, enabling targeted antifreeze in actual vehicle parking and preparation scenarios.

[0083] It should be understood that the above examples are merely illustrative and not limiting. In one possible embodiment, the meteorological data source, risk analysis method, command mapping method, and specific configuration of the anti-freezing actuator can be adjusted according to the vehicle platform and vehicle networking architecture. As long as remote anti-icing control based on the icing risk level can be achieved, it falls within the scope of this application.

[0084] In one possible implementation, in S103 above, when outputting the corresponding anti-icing control command according to the icing risk level, specifically, when the icing risk level is low or medium risk, an icing warning message can be pushed to the user terminal; when the icing risk level is high risk, an anti-icing control command can be output, and feedback can be sent to the user terminal that the anti-icing operation has been enabled.

[0085] After determining the icing risk level, the control module can read the current icing risk level and process it accordingly. When the icing risk level is low or medium, the control module generates a warning message containing the icing risk level, prompt content, and vehicle identification information, which is sent to the user terminal via the communication link. The user terminal then displays a pop-up window, push notification, or status bar notification. This warning message can be displayed in conjunction with the vehicle's current location, expected icing trend, and icing risk level, informing the user that the vehicle may experience icing in the near future.

[0086] When the icing risk level is high, the control module generates an anti-icing control command and sends it to the vehicle-mounted execution unit to trigger windshield heating, wiper defrosting, or other anti-freezing strategies. Simultaneously, it generates a status feedback message and sends it to the user terminal. For example, the message may include a status field indicating "Anti-icing operation is enabled." The user can also set the execution component, execution duration, and timed start / end times for the anti-icing command through the user terminal, and remotely send commands to the vehicle-mounted unit to execute the corresponding functions.

[0087] Anti-icing control commands and status feedback can be transmitted via the vehicle communication module through the mobile network or vehicle network channel. After the status feedback reaches the user terminal, the application will display the current vehicle status as performing anti-icing operation.

[0088] The technical solution in this embodiment achieves remote linkage control under risk classification by assigning different output content to different icing risk levels. For low or medium risk situations, the focus is on early warning prompts, while for high risk situations, anti-icing control is directly initiated and the execution status is simultaneously fed back. With this solution, user terminals can obtain timely risk warnings and execution status updates, vehicles can initiate anti-icing procedures earlier in high-risk phases, control responses are more consistent, and status information transmission is clearer.

[0089] In one possible implementation, before S104, and before executing the corresponding antifreeze strategy in response to the anti-icing control command, the method provided in this embodiment may first allow the user to confirm the actual icing state. Specifically, as shown... Figure 2 As shown, based on the above embodiments, the method provided in this embodiment may include:

[0090] S201. In response to a remote viewing command triggered by a user terminal, the vehicle-mounted image acquisition module is activated to acquire real-time images of the windshield area; the real-time images include at least the images of the windshield wipers.

[0091] S202. The real-time image is transmitted back to the user terminal for visualization display, so that the user can confirm the actual icing status.

[0092] Specifically, upon responding to a remote viewing command, the vehicle-side controller wakes up the onboard image acquisition module, switching it from a low-power standby state to an operating state, and acquires images of the windshield area at a preset sampling frequency. The acquired images are then processed by the image processing unit to generate real-time images, which are transmitted back to the user terminal via the vehicle-to-everything (V2X) communication link. Upon receiving the image data, the user terminal decodes it and displays it on the screen, allowing the user to check the ice accumulation around the wipers, the frost condition on the glass surface, and the local transparency before implementing anti-freeze strategies.

[0093] The technical solution of this embodiment can provide the user with on-site visual information of the windshield area before the vehicle executes the anti-icing control command, so that the activation of the anti-freezing strategy matches the actual icing state, and the user can directly judge whether the wiper area has frozen on the user terminal side, thereby providing a basis for subsequent control and improving the timeliness and reliability of anti-icing control.

[0094] In one possible implementation, the anti-icing control command includes at least one of the following: a one-click antifreeze command for simultaneously executing wiper vertical adjustment and heating de-icing; a wiper vertical adjustment command for executing wiper vertical adjustment; and a heating de-icing command for executing heating de-icing.

[0095] In its specific implementation, the wiper drive mechanism includes a motor, a transmission link and a swing arm assembly. The motor output shaft drives the swing arm assembly to move through a reduction mechanism. The end of the swing arm assembly is hinged to the wiper arm. After receiving the wiper vertical position command, the vehicle controller outputs a vertical position control signal to drive the motor to rotate to a preset angle, and the limit structure locks the wiper arm in a vertical state.

[0096] The heating and de-icing process includes a heating film attached to the inner surface of the windshield and localized heating elements located in the wiper rest area. The heating film can be made of conductive heating material, and the localized heating elements can be made of resistance wire or flexible heating sheet. After receiving a heating and de-icing command, the vehicle controller energizes both components for a preset time to heat and de-ic the glass surface and wiper area. The windshield heating module and wiper heating module act on the windshield surface and wiper area respectively, forming a zoned heating structure to improve heating efficiency and reduce energy consumption.

[0097] The control logic corresponding to the one-button antifreeze command is to simultaneously issue a vertical control signal and a heating drive signal, enabling the two execution units to work in parallel. Other models of the aforementioned motor, heating film, and heating element can also be selected in practical applications; this application does not limit this selection.

[0098] This anti-icing control command system unifies individual attitude control, individual heating control, and linkage control into a single command interface, enabling the vehicle to execute corresponding controls based on the icing risk level, user selection, or remote triggering status. The vehicle controller can directly complete the corresponding actions and output status feedback.

[0099] In practical applications, when the anti-icing control command is a one-button antifreeze command, in response to this command, the wiper drive mechanism is controlled to vertically position the wipers, raising them from their normal parking position to the vertically locked position. The windshield heating module and wiper heating module are also activated to heat and defrost the windshield and wipers. When the anti-icing control command is a wiper vertical position command, in response, the wiper drive mechanism is controlled to vertically position the wipers, raising them from their original parking position to the vertically locked position. When the anti-icing control command is a heating and de-icing command, in response, the windshield heating module and wiper heating module are activated to heat and defrost the windshield and wipers. The vertically locked position includes locking limit logic to prevent the wipers from automatically retracting under low-temperature conditions.

[0100] In actual control, after receiving the one-button antifreeze command, the vehicle controller first outputs a wiper verticalization control signal to the wiper drive mechanism, causing the wipers to move from the normal parking position to the vertical locking position. This detaches the wiper blades from the windshield surface, preventing them from freezing and sticking to the glass under low-temperature conditions. Simultaneously, it sends power-on commands to the windshield heating module and the wiper heating module to continuously heat and defrost the windshield surface and wiper blade area. When receiving the wiper verticalization command, the vehicle controller only drives the wipers into the vertical locking position to raise the wipers without activating heating. When receiving the heating and defrosting command, the vehicle controller activates only the two types of heating modules to heat and defrost the windshield and wipers. The locking limit logic can trigger the limit holding state after the wiper reaches the target angle. The wiper arm is fixed in the vertical locking position by mechanical buckle or electromagnetic locking. Combined with low temperature judgment to prevent the wiper from falling back, the wiper is kept in a vertical position and the wiper is prevented from falling back to the normal parking position due to gravity or external force under low temperature conditions.

[0101] In other words, upon receiving different anti-icing control commands, the system can independently control the wiper vertical positioning, synchronous heating, or individual heating, ensuring the wipers remain stably raised under low-temperature conditions and providing targeted heating to areas prone to icing. This allows for coordinated antifreeze treatment of both the wiper area and the windshield area without altering the overall vehicle anti-icing control chain.

[0102] In this embodiment, the windshield wipers can maintain a vertically locked position in low-temperature environments. The windshield and wipers can be heated and de-iced synchronously or independently according to the anti-icing control command, reducing the probability of wipers freezing and sticking and falling back out of control, and shortening the thawing preparation time before using the vehicle in winter.

[0103] Based on the foregoing embodiments, the method provided in this embodiment may further include: real-time acquisition of environmental parameters; when the icing risk level is detected to be reduced to no risk, or when the user-set timeout ends, turning off the windshield heating module and wiper heating module, and controlling the wiper drive mechanism to perform wiper fall-down processing on the wipers so that the wipers fall back to the normal parking position; and feeding back to the user terminal that the anti-icing operation has ended.

[0104] During actual control, the vehicle controller continuously collects environmental parameters and monitors the current icing risk level. When it determines that the icing risk level has decreased to no risk, or when the preset time has elapsed, it outputs a shutdown command to shut down both heating modules and simultaneously sends a fallback control signal to the wiper drive mechanism, causing the wipers to complete the fallback process. After the wiper fallback process is completed, the vehicle controller sends an end status information to the user terminal, which updates the interface display accordingly, allowing the user to confirm that the anti-icing operation has ended. Through the above process, the vehicle can promptly stop heating and restore the wipers to the normal parking position when the risk disappears or the preset time has elapsed, thereby completing the closed-loop control of the entire anti-icing operation process. At the same time, it reduces unnecessary continuous working time and component occupancy, reduces energy consumption, and extends the service life of the heating modules.
