DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] It is important to understand that with the changes in the automobile market, the proportion of hybrid models in the market is increasing. Compared with traditional fuel vehicles, customers have higher and higher requirements for the range of hybrid models. The current technical solutions are large oil and small electricity or small oil and large electricity. Regardless of the solution, it affects the layout space of the exhaust system, resulting in the exhaust system's silencer volume gradually becoming smaller, resulting in the deterioration of the NVH of the entire vehicle, affecting the customer's driving experience.

[0019] To compensate for the insufficient noise reduction capacity of the exhaust system, active noise reduction valve technology has been applied to the exhaust system. This technology improves the noise reduction effect to a certain extent through the regulation of the active noise reduction valve.

[0020] However, when customers drive their vehicles in low-temperature environments, the active muffler valve body is located at the end of the tail pipe. The hot air discharged from the tail pipe forms convection with the low-temperature environment, and the high-temperature gas liquefies into water and freezes. Or, after the vehicle stops, the condensed water at the tail pipe is not discharged from the tail pipe in time, which will cause the active muffler valve body to freeze. When the active muffler valve body freezes, the EMS controller sends the required command, but the active muffler valve actuator cannot work as required, affecting the normal use of the vehicle.

[0021] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0022] In a first aspect, an embodiment of the present application provides a method for handling icing of an active muffler valve in an exhaust system.

[0023] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for treating ice formation in the active muffler valve of the exhaust system of this application. Figure 1 As shown, the method for dealing with ice formation on the active muffler valve of the exhaust system includes: S100: Real-time monitoring of vehicle status and active muffler valve icing status; S200: If the monitored engine speed is greater than or equal to the idle threshold and the active muffler valve is detected to be in an iced state, multiple groups of interval ice-breaking operations are cyclically executed, with each group performing multiple active muffler valve opening and closing actions.

[0024] In this embodiment, the idle speed threshold is used as the ice breaking starting condition. Compared with the high speed threshold, ice breaking can be intervened earlier to avoid the continuous condensation and thickening of the ice layer in a low temperature environment. For example, ice breaking can be performed synchronously during the idle warm-up stage after the vehicle is started, so as to prevent the ice blockage problem from worsening over time; through a cyclic mechanism of multiple groups and multiple opening and closing actions, continuous mechanical impact is formed on the iced parts, and the thermal melting effect of the exhaust temperature in the idle stage is combined to achieve the synergistic effect of "mechanical crushing + thermal melting" to avoid residual ice blockage caused by the failure of a single operation; the cyclic ice breaking strategy avoids the continuous high-load operation of the silencer valve actuator through batch and intermittent actions, thereby reducing after-sales maintenance costs; at the same time, the natural masking effect of the engine noise in the idle stage on the abnormal sound of ice breaking is utilized, so that the abnormal sound is dispersed in the idle noise background, and the subjective perception of the human ear is reduced; this method can enable the vehicle to quickly complete ice breaking after starting, ensure the normal operation of the silencer valve, and improve the availability and driving convenience of vehicles in cold areas.

[0025] Furthermore, in one embodiment, the method for treating ice formation on an active muffler valve of an exhaust system further includes S300, which includes the following steps: S301: Using the Internet of Vehicles module to obtain weather forecast data and parking duration data of the vehicle's current location in real time; S302: Importing weather forecast data and parking duration data obtained at the vehicle's current location into a trained neural network model, and inputting an icing probability of the active muffler valve based on the trained neural network model; S303: If the probability of the active muffler valve freezing exceeds a preset threshold and a remote start instruction is received from the user via a mobile terminal, multiple groups of interval ice-breaking operations are cyclically executed, with each group performing multiple active muffler valve opening and closing actions.

[0026] In this embodiment, the Internet of Vehicles module is used to obtain weather forecast data and parking duration data for the vehicle's current location in real time, and a trained neural network model is imported. This can accurately predict the probability of active muffler valve freezing based on a comprehensive analysis of low temperature weather conditions and parking duration. When the probability of active muffler valve freezing exceeds a preset threshold and a user remote start command is received, a cyclic multiple-group interval ice-breaking operation is performed. Compared with the passive response method that relies solely on real-time monitoring, this method can actively intervene before the vehicle is started, eliminate potential ice hazards in advance, and avoid muffler valve failure due to ice after the vehicle is started. By incorporating weather forecast data and parking duration into the prediction model, environmental data is effectively used to plan ice-breaking strategies in advance, reducing unnecessary ice-breaking operations and reducing actuator wear. Remote start combined with a pre-judgment ice-breaking mechanism can complete the thawing of the muffler valve before the user actually uses the vehicle, ensuring that the muffler system operates normally immediately after the vehicle is started, significantly improving the vehicle's convenience and user experience in cold areas, while reducing after-sales maintenance costs caused by muffler valve freezing failures.

[0027] Furthermore, in one embodiment, S300 ( S301 , S302 and S303 ) and S200 are performed in no particular order.

[0028] Furthermore, in one embodiment, in S200, the following steps are included: S200-1: During the execution of multiple sets of interval ice-breaking operations, if the engine speed is lower than the idle threshold, the active muffler valve ice-breaking operation is immediately terminated and the current execution progress is saved. When the ice-breaking conditions are met again, the unfinished ice-breaking groups are continued based on the saved current execution progress.

[0029] In this embodiment, during the execution of multiple groups of interval ice-breaking operations, the active muffler valve ice-breaking operation is immediately terminated and the current execution progress is saved when the engine speed is set to be lower than the idle threshold. This can effectively avoid the poor ice-breaking effect due to insufficient exhaust volume and low temperature under low engine speed conditions, and even the aggravation of the actuator load due to forced operation; when the ice-breaking conditions are met again, the unfinished ice-breaking groups are continued to be executed based on the saved execution progress, which can continue the previous ice-breaking effect and avoid repeated operations causing waste of resources and excessive wear of the actuator; this mechanism enables the ice-breaking operation to closely fit the engine operating conditions, and flexibly adjust when the engine operating state changes, to ensure the effectiveness and continuity of the ice-breaking operation, to prevent the negative impact of blindly executing operations under inappropriate operating conditions, and to ensure that the active muffler valve icing problem is finally solved, thereby improving the operating adaptability and reliability of the exhaust system active muffler valve icing treatment method, and reducing the risk of equipment damage and maintenance costs caused by abnormal operating conditions.

[0030] Furthermore, in one embodiment, the method for treating ice formation on an active muffler valve of an exhaust system further includes the following steps: S400: If the engine is detected to be flameout or the vehicle is powered off, the active muffler valve is controlled to open to a preset intermediate transition opening.

[0031] In this embodiment, when the engine is detected to be stalled or the entire vehicle is powered off, the active muffler valve is controlled to open to a preset intermediate transition opening (such as 45%, 50% or 55% opening). This can prevent the condensed water remaining in the tail pipe from freezing and sticking to the valve body due to the low ambient temperature when the active muffler valve is closed, effectively preventing the valve body from freezing and causing failure to open and close normally during subsequent startup; the preset intermediate transition opening can provide a smoother discharge channel for gas and condensed water in the tail pipe when the vehicle stops running, reduce condensed water accumulation, and reduce the risk of freezing from the source; this setting does not require additional heating or complicated operations, and can prevent the hidden danger of freezing through simple opening control. Compared with other preventive measures, it is cheaper and more reliable. At the same time, when the vehicle is started next time, the active muffler valve can return to normal working state more quickly, ensuring the continuous and stable operation of the muffler system, improving the stability of the vehicle during use and the user's satisfaction with the vehicle performance.

[0032] Furthermore, in one embodiment, S400 , S300 , and S200 are performed in any order.

[0033] Furthermore, in one embodiment, in S100, the following steps are included: S101: Using a torque sensor built into the active muffler valve to monitor the opening and closing resistance of the active muffler valve in real time; S102: If the opening and closing resistance of the active muffler valve exceeds a preset resistance threshold, it is determined that the active muffler valve is blocked by ice.

[0034] In this embodiment, the torque sensor built into the active muffler valve is used to monitor the opening and closing resistance in real time. This can accurately convert the restricted valve movement caused by ice formation into quantifiable resistance data. When the opening and closing resistance of the active muffler valve exceeds a preset resistance threshold, ice blockage is determined to be present. Compared with the traditional method of determining the icing status based on indirect parameters such as temperature and humidity, this determination method is more direct and sensitive, and can quickly and accurately identify whether the active muffler valve is frozen, avoiding the deterioration of the icing problem due to delayed determination. Using the real-time resistance data collected by the torque sensor as the basis for judgment, anomalies can be detected promptly at the early stage of ice blockage, allowing more time for subsequent ice-breaking operations, effectively improving the timeliness and effectiveness of ice treatment. At the same time, this monitoring method is based on the structure of the muffler valve itself, eliminating the need for additional complex monitoring equipment, reducing the cost and complexity of the monitoring system, and is highly reliable. It can stably and continuously provide data support for determining the icing status of the active muffler valve, ensuring the reliable operation of the ice treatment process of the active muffler valve in the exhaust system.

[0035] Furthermore, in one embodiment, in S200, the following steps are included: S200-2: If the opening and closing resistance of the active muffler valve exceeds a first preset resistance threshold, cyclically executing M groups of interval ice-breaking operations, each group performing multiple opening and closing actions of the active muffler valve; S200-3: If the opening and closing resistance of the active muffler valve exceeds the second preset resistance threshold, N groups of interval ice-breaking operations are executed cyclically, and each group performs multiple opening and closing actions of the active muffler valve; wherein the second preset resistance threshold is greater than the first preset resistance threshold, and N is greater than M.

[0036] In this embodiment, the number of cyclic ice-breaking operations is differentiated based on the comparison of the active muffler valve's opening and closing resistance with different preset resistance thresholds, achieving precise matching of the ice-breaking strategy. When the opening and closing resistance exceeds the first preset resistance threshold, M groups of intermittent ice-breaking operations are performed, specifically addressing mild ice blockages. This effectively clears the ice while avoiding unnecessary actuator wear caused by excessive operation. When the resistance exceeds the second, larger preset resistance threshold, N groups of intermittent ice-breaking operations are increased, providing more comprehensive and sustained mechanical impact and thermal treatment for severe ice blockages, ensuring complete ice removal. This graded treatment mechanism matches the intensity of ice-breaking operations to the actual severity of ice blockages, ensuring effective treatment of all ice blockages and improving the success rate of ice treatment. By properly controlling the operation intensity, it also extends the service life of the active muffler valve actuator and reduces maintenance costs. Furthermore, it avoids the energy waste and additional noise caused by excessive treatment of mild ice blockages, optimizing the vehicle's overall performance during ice-breaking.

[0037] For example, based on the comparison results of the opening and closing resistance of the active silencer valve and different preset resistance thresholds, the number of groups of cyclic icebreaking operations is set differently, thereby achieving precise matching of the icebreaking strategy. When the opening and closing resistance exceeds the first preset resistance threshold of 5N·m, three sets of intermittent ice-breaking operations are executed, with each set performing five active muffler valve opening and closing operations. This setting can specifically address mild ice blockages, effectively clearing the ice while avoiding unnecessary wear and tear on the actuator caused by excessive operation. When the resistance exceeds the second, larger preset resistance threshold of 8N·m, the number of intermittent ice-breaking operations is increased to five sets, with each set performing five active muffler valve opening and closing operations. This can provide more sufficient and continuous mechanical impact and thermal effects on severe ice blockages, ensuring complete removal of the ice. This graded treatment mechanism matches the intensity of ice-breaking operations to the actual severity of the ice blockage, ensuring that all degrees of ice blockage are effectively handled and improving the success rate of ice treatment. It also extends the service life of the active muffler valve actuator and reduces maintenance costs by properly controlling the operation intensity. It also avoids the energy waste and additional noise caused by excessive treatment of mild ice blockages, optimizing the vehicle's overall performance during ice-breaking.

[0038] Furthermore, in one embodiment, in S200, the following steps are included: S200-4: If the monitored engine speed is greater than or equal to the idle threshold and the active muffler valve is detected to be in an iced state, multiple groups of interval ice-breaking operations are executed cyclically, with each group performing multiple active muffler valve opening and closing actions, and the electric heating film built into the exhaust manifold is activated to accelerate the melting of ice on the active muffler valve.

[0039] In this embodiment, when the engine speed is detected to be greater than or equal to the idle threshold and the active muffler valve is frozen, the exhaust manifold's built-in electric heating film is activated, in addition to executing multiple sets of intermittent ice-breaking operations and multiple opening and closing cycles of the active muffler valve. This dual-action mechanism significantly improves ice-breaking efficiency through a combination of mechanical ice-breaking and thermal ablation. The opening and closing of the active muffler valve mechanically impacts the ice layer, breaking up the surface ice, while the heat generated by the electric heating film directly affects the exhaust system, raising exhaust temperature and accelerating ice melting. These two coordinated mechanisms can more quickly and thoroughly eliminate ice on the active muffler valve compared to a single ice-breaking method. Furthermore, the built-in electric heating film in the exhaust manifold allows for precise control of the heating area and temperature, avoiding adverse effects on other exhaust system components. This ensures effective ice-breaking while reducing energy consumption. This method also reduces the risk of secondary ice formation caused by residual ice, ensuring that the active muffler valve quickly returns to normal operation. This further improves vehicle reliability and driving experience in low-temperature environments, effectively resolving the issue of active muffler valve ice affecting vehicle performance in low-temperature environments.
