[0048] 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.

[0049] 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.

[0050] The main solution of the embodiment of the present application is: determining the target vehicle state based on the vehicle-related data set; when the target vehicle state is a hybrid state, determining the target hybrid mode based on the hybrid-related data set; determining the target tuning valve opening based on the target hybrid mode; and controlling the tuning valve based on the target tuning valve opening.

[0051] The tuning valve control method in hybrid vehicles is mainly applied to the vehicle's exhaust system, aiming to improve the driving experience and the vehicle's sound quality by controlling the characteristics of the exhaust sound. In hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs), the sound of the traditional internal combustion engine may become less noticeable due to the addition of the electric motor, which affects the driver's perception of vehicle dynamics, especially at low speeds and in pure electric mode. Therefore, the control of the tuning valve has become a means to enhance the vehicle's sound characteristics, improve driving pleasure and brand recognition, but the existing tuning valve control method only solves the noise problem of pure gasoline vehicles, does not target the noise of hybrid vehicles at idle and high load conditions, and cannot cover the various driving modes of hybrid vehicles. Therefore, how to accurately control and reduce the noise of hybrid vehicles in various driving states has become an urgent problem to be solved.

[0052] This application determines a target vehicle state based on a vehicle-related data set; when the target vehicle state is a hybrid state, determines a target hybrid mode based on the hybrid-related data set; determines a target tuning valve opening based on the target hybrid mode; and controls the tuning valve based on the target tuning valve opening. The vehicle's driving state is determined using collected vehicle driving data. When the vehicle is in a hybrid state, the type of hybrid mode is determined based on the vehicle driving data associated with the hybrid mode, and the corresponding tuning valve opening is determined. Finally, the tuning valve opening is adjusted, thereby achieving precise control to reduce noise in various driving states of the hybrid vehicle and reducing the failure rate of the catalyst.

[0053] It should be noted that the execution entity of this embodiment may be a computing service device with data processing, network communication, and program execution capabilities, such as a tablet computer, personal computer, or mobile phone, or a tuning valve control device capable of performing the aforementioned functions. This embodiment and the following embodiments will be described below using the tuning valve control device as the execution entity.

[0054] Based on this, the embodiment of the present application provides a tuning valve control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the tuning valve control method of the present application.

[0055] In this embodiment, the tuning valve control method includes steps S10 to S40:

[0056] Step S10, determining the target vehicle state according to the vehicle association data set;

[0057] It should be noted that if Figure 2 As shown, this embodiment moves the control of the tuning valve to the PDCM power domain controller. Compared with the EMS, this controller can interact with the IPB, BMS, EMS and other vehicle controllers, and obtain important vehicle information such as vehicle speed, battery SOC, engine speed, driving mode, pedal opening, etc., and send instructions to the tuning valve through the PDCM controller based on the established strategy to adjust the valve opening of the tuning valve. Under the premise of not affecting the back pressure and reducing the engine power, the exhaust noise is reduced, thereby improving the comfort of the whole vehicle. After the PDCM determines that the vehicle has entered the floating state, it can completely close the tuning valve to reduce the amount of sewage entering the exhaust system and causing the catalyst to be blocked. At the same time, the PDCM has the function of uploading historical fault information, which can record the status of the tuning valve in real time. When a fault occurs, it will be reported to the PDCM and fed back to the instrument to remind the customer. At the same time, historical fault information is used to facilitate fault troubleshooting.

[0058] It can be understood that the vehicle-related data set refers to a data set composed of vehicle driving-related data, including important vehicle information such as vehicle speed, battery SOC, engine speed, driving mode, pedal opening, etc. The target vehicle status includes high-voltage state, pure electric state, hybrid state and floating state.

[0059] In practice, the system collects key vehicle information, including speed, battery SOC, engine speed, driving mode, and pedal stroke, and then determines the vehicle's current driving state based on this collected driving data. For example, a high-voltage state refers to the vehicle's high-voltage electrical system being in operation, typically involving the battery pack and electric motor in hybrid and electric vehicles. When the battery SOC is high and the vehicle is in driving mode, the control system may prioritize the use of electrical energy, placing the vehicle in a high-voltage state.

[0060] In a feasible implementation manner, step S10 may include steps A11 to A13:

[0061] Step A11, when the target vehicle state is a high-voltage state or a pure electric state, determining a first preset opening as a target tuning valve opening;

[0062] It can be understood that the first preset opening refers to the tuning valve opening corresponding to the preset high-pressure state or pure electric state, and the target tuning valve opening is used to control the opening size of the vehicle tuning valve.

[0063] In specific implementation, based on the collection of important vehicle information such as vehicle speed, battery SOC, engine speed, driving mode, pedal opening, etc., it is determined that the vehicle is in a high-voltage state or a pure electric state, and the tuning valve opening corresponding to the pre-set high-voltage state or pure electric state is used as the target tuning valve opening. Among them, the pre-set tuning valve opening corresponding to the high-voltage state or pure electric state can be determined through vehicle calibration to determine the optimal tuning valve opening corresponding to the high-voltage state or pure electric state.

[0064] It should be noted that when the vehicle is in the low-pressure state: the engine is not working, the tuning valve is 100% open, to avoid water and other foreign matter inside the exhaust pipe, which may cause the valve body and the exhaust pipe to rust and get stuck; when the vehicle is in the pure electric state: the engine is not working, the tuning valve is 100% open, to avoid water and other foreign matter inside the exhaust pipe, which may cause the valve body and the exhaust pipe to rust and get stuck.

[0065] Step A12: when the target vehicle state is a floating state, determining a second preset opening as a target tuning valve opening, wherein the second preset opening is smaller than the first preset opening;

[0066] It can be understood that the floating state refers to a special state of a vehicle when it is traveling in water, and the second preset opening refers to the preset opening of the tuning valve corresponding to the floating state.

[0067] In the specific implementation, based on the collection of important vehicle information such as vehicle speed, battery SOC, engine speed, driving mode, pedal opening, etc., when it is determined that the vehicle is in a floating state, the tuning valve opening corresponding to the pre-set floating state is used as the target tuning valve opening.

[0068] It should be noted that when the vehicle is in a floating state: the tuning valve opening is 0%, which is completely closed to prevent sewage from entering the exhaust system and clogging the catalyst.

[0069] Step A13: Control the tuning valve according to the target tuning valve opening.

[0070] It is understandable that the tuning valve of the vehicle is adjusted according to the size of the tuning valve opening value corresponding to the vehicle operating state to achieve precise control of the tuning valve opening, thereby achieving the purpose of accurately controlling and reducing the noise of the hybrid vehicle in various driving states.

[0071] Step S20, when the target vehicle state is a hybrid state, determining a target hybrid mode according to a hybrid associated data set;

[0072] It can be understood that the hybrid-related data set refers to a data set used to determine the type of hybrid mode. The hybrid-related data set includes battery SOC, power load, engine speed, etc. The target hybrid mode includes idle charging mode, extended range mode and direct drive mode.

[0073] In practice, when the vehicle is in idle charging mode (a state where the vehicle is stationary and free from tire or wind noise), the charging power is set to low, medium, or high, corresponding to different engine speeds, to improve NVH performance. The tuning valve opening should be minimized to attenuate exhaust noise and enhance vehicle comfort. During idle low-power charging, the engine speed is low, set between 900 and 1000 rpm, and the tuning valve operates at preset value A. During idle medium-power charging, the engine speed is medium, set between 1100 and 1200 rpm, and the tuning valve operates at preset value B. During idle high-power charging, the engine speed is high, set between 1300 and 1400 rpm, and the tuning valve operates at preset value C.

[0074] When the vehicle is in extended-range mode, the engine only participates in power generation. This is typically set based on vehicle speed, typically between 80 km / h and 140 km / h. The range-extended mode selection is based on engine thermal efficiency. In low-speed extended-range mode, the engine speed is typically below 1800 rpm, with a narrow speed range. The tuning valve opening is set to preset value D. In high-speed extended-range mode, the engine speed is typically between 3000 and 4000 rpm, with a wide speed range. Below 3500 rpm, the tuning valve opening is set to preset value E to reduce noise. Above 3500 rpm, the tuning valve opening is set to 100% to reduce backpressure and maintain engine performance.

[0075] When the vehicle is in direct drive mode: the engine and wheels are directly connected. In order to better respond to the engine speed and ensure the linearity of noise and back pressure changes, the opening of the tuning valve changes linearly with the engine speed between the preset values ​​DE.

[0076] Step S30, determining a target tuning valve opening according to the target hybrid mode;

[0077] It can be understood that the corresponding tuning valve opening is determined by calibrating the correspondence between the vehicle's hybrid mode and the tuning valve opening. For example, when the vehicle is in extended-range mode, the engine is only engaged in power generation. This is generally set based on vehicle speed, typically between 80 km / h and 140 km / h. In extended-range mode, the opening is selected based on engine thermal efficiency. In low-speed extended-range mode, the engine speed is generally below 1800 rpm, with a narrow engine speed range, and the tuning valve opening is set to preset value D. In high-speed extended-range mode, the engine speed is generally between 3000 and 4000 rpm, with a wide engine speed range. Below 3500 rpm, the tuning valve opening is set to preset value E to reduce noise. Above this, a 100% opening is used to reduce backpressure and maintain engine performance.

[0078] In a feasible implementation, step S30 may include steps A31 to A32:

[0079] Step A31, when the target hybrid mode is the extended-range mode, determining a vehicle speed comparison result based on the current vehicle speed, a first vehicle speed threshold, and a second vehicle speed threshold, wherein the first vehicle speed threshold is less than the second vehicle speed threshold;

[0080] It can be understood that the current vehicle speed refers to the current vehicle driving speed, the first vehicle speed threshold and the second vehicle speed threshold are both speed critical values ​​used to determine the current vehicle driving speed, and the vehicle speed comparison result is used to determine the high-speed extended-range mode and the low-speed extended-range mode.

[0081] It should be noted that when the vehicle is in extended-range mode: the engine only participates in power generation, which is generally set according to the vehicle speed, generally below 80km / h and above 140km / h. In extended-range mode, the point is selected according to the engine thermal efficiency.

[0082] In a specific implementation, when the vehicle is in the extended-range mode, the current vehicle speed is compared with the first speed threshold and the second speed threshold, thereby obtaining a comparison result between the current vehicle speed and the first speed threshold and the second speed threshold, that is, a speed comparison result.

[0083] Step A32: determining a corresponding target tuning valve opening according to the vehicle speed comparison result.

[0084] In a specific implementation, the type of hybrid mode of the vehicle is determined based on the result of the vehicle speed comparison, and then the corresponding tuning valve opening is determined. For example, when the current vehicle speed is less than the first vehicle speed threshold, it is determined that the vehicle is in the low-speed extended-range mode, and then the tuning valve opening corresponding to the low-speed extended-range mode is determined as the target tuning valve opening.

[0085] In a feasible implementation, step A32 may include steps B321 to B322:

[0086] Step B321: When the vehicle speed comparison result shows that the current vehicle speed is less than the first vehicle speed threshold, determining the fourth tuning valve opening as the target tuning valve opening, wherein the fourth tuning valve opening is greater than the third tuning valve opening;

[0087] It can be understood that the fourth tuning valve opening refers to a preset tuning valve opening corresponding to the low-speed extended-range mode.

[0088] In a specific implementation, when the current vehicle speed is less than the first vehicle speed threshold, the vehicle is determined to be in the low-speed extended-range mode, and then the tuning valve opening corresponding to the preset low-speed extended-range mode is determined as the target tuning valve opening.

[0089] Step B322: When the vehicle speed comparison result shows that the current vehicle speed is greater than the second vehicle speed threshold, a corresponding target tuning valve opening is determined according to the current engine speed and a preset speed range.

[0090] It can be understood that the preset speed range refers to the engine speed range corresponding to the preset high-speed range extension mode.

[0091] In a specific implementation, when the current vehicle speed is greater than the second vehicle speed threshold, it is determined that the vehicle is in the high-speed range extension mode, and then the current engine speed is collected, and then the target tuning valve opening is determined through the pre-set engine speed range corresponding to the high-speed range extension mode.

[0092] It should be noted that when in high-speed range extension mode: the engine is generally between 3000 and 4000 rpm, and the engine speed range is large. Below 3500 rpm, the tuning valve opening executes the preset value E to reduce noise. Above 3500 rpm, the opening is 100% to reduce back pressure and ensure engine performance.

[0093] In a feasible implementation, step S30 may include steps C31 to C32:

[0094] Step C31, when the target hybrid mode is the direct drive mode, determining a tuning valve opening range according to a fourth tuning valve opening and a fifth tuning valve opening, wherein the fifth tuning valve opening is greater than the fourth tuning valve opening;

[0095] It can be understood that the tuning valve opening range refers to the tuning valve opening range corresponding to the direct drive mode. For example, the fourth tuning valve opening is D, and the fifth tuning valve opening is E, so the tuning valve opening range is DE, that is, the tuning valve opening corresponding to the direct drive mode is between DE.

[0096] Step C32: determining a target tuning valve opening according to the current engine speed and the tuning valve opening range.

[0097] It can be understood that when the vehicle is in direct drive mode: the engine and wheels are directly connected. In order to better respond to the engine speed and ensure the linearity of noise and back pressure changes, the tuning valve opening changes linearly with the engine speed between the preset values ​​DE. Through the linear change relationship between the tuning valve opening and the engine speed, the tuning valve opening corresponding to the current engine speed is calculated, that is, the target tuning valve opening is obtained.

[0098] It's important to note that to achieve a linear relationship between tuning valve opening and engine speed, the target range (D to E) for tuning valve opening must be defined. The effective operating range of engine speed must then be determined, from idle to maximum speed or the upper limit of the commonly used speed. Reference points are set at either end of the speed range. For example, when the engine speed is at its lowest effective speed, the tuning valve opening is D, and when the engine speed is at its highest effective speed, the tuning valve opening is E. Based on these two reference points, a linear equation can be used to describe the relationship between tuning valve opening and engine speed. The linear equation typically takes the form y = mx + b, where y is the tuning valve opening, x is the engine speed, m is the slope, and b is the tuning valve opening increment. After determining the linear equation, testing is performed on an actual vehicle to ensure that the relationship between tuning valve opening and engine speed meets the desired sound and performance requirements. If necessary, the linear equation can be fine-tuned based on the test results.

[0099] Step S40: Controlling the tuning valve according to the target tuning valve opening.

[0100] It is understandable that if Figure 3 As shown, this embodiment shifts the control requirements for the exhaust tuning valve to the PDCM. In hybrid vehicles, the EMS, acting as a downstream actuator of the PDCM, is also controlled by the PDCM, enabling better identification of vehicle information such as speed, pedal position, driving mode, charge / discharge status, and engine speed. This allows for more precise control of the tuning valve opening and overall vehicle noise. During idle charging, the engine operates at different speeds to accommodate varying charging power levels. By adjusting the tuning valve opening to suit the vehicle's state, noise and backpressure are balanced. The PDCM closes the tuning valve when the vehicle is in float mode, minimizing wastewater from entering the exhaust system and potentially clogging the catalyst. The PDCM also features the ability to upload historical fault information, recording tuning valve failures for easier troubleshooting and repair.

[0101] This embodiment determines a target vehicle state based on a vehicle-related data set; when the target vehicle state is a hybrid state, determines a target hybrid mode based on the hybrid-related data set; determines a target tuning valve opening based on the target hybrid mode; and controls the tuning valve based on the target tuning valve opening. The vehicle's driving state is determined based on collected vehicle driving data. When the vehicle is in a hybrid state, the hybrid mode type is determined based on the hybrid-mode-related vehicle driving data, and the corresponding tuning valve opening is determined. Finally, the tuning valve opening is adjusted, achieving precise control to reduce noise in various driving states of the hybrid vehicle and lowering the failure rate of the catalyst.

[0102] 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 In the tuning valve control method, step S30 further includes steps S31 to S32:

[0103] Step S31, when the target hybrid mode is the idle charging mode, determining the target charging power according to the remaining power of the vehicle and the vehicle power load;

[0104] It can be understood that the vehicle's remaining power refers to the vehicle's current remaining power value, and the target charging power refers to the vehicle's current charging power size.

[0105] It should be noted that when the vehicle is in idle charging mode, the vehicle is stationary and free from tire and wind noise. To improve NVH performance, the charging power is set to low, medium, or high, corresponding to different engine speeds, based on the battery SOC and power load. The tuning valve opening should be minimized to attenuate exhaust noise and enhance vehicle comfort.

[0106] Step S32: determining a corresponding target tuning valve opening according to the target charging power.

[0107] It can be understood that when in idle low-power charging: the engine speed is low, set between 900 and 1000 rpm, the tuning valve executes the preset value A; when in idle medium-power charging: the engine speed is medium, set between 1100 and 1200 rpm, the tuning valve executes the preset value B; when in idle high-power charging: the engine speed is high, set between 1300 and 1400 rpm, the tuning valve executes the preset value C.

[0108] In a feasible implementation, step S32 may include steps A321 to A323:

[0109] Step A321: When the target charging power is the first charging power, determine the first tuning valve opening as the target tuning valve opening;

[0110] It can be understood that the first charging power refers to the low power of idling charging, and the first tuning valve opening refers to the preset tuning valve opening corresponding to the idling low power charging.

[0111] In a specific implementation, when the vehicle charging power is in idle low-power charging, the engine speed is low, between 900 and 1000 rpm, so the tuning valve implements the preset value A (the first tuning valve opening).

[0112] Step A322: When the target charging power is a second charging power, determining the second tuning valve opening to be the target tuning valve opening, the second charging power is greater than the first charging power, and the second tuning valve opening is greater than the first tuning valve opening;

[0113] It can be understood that the first charging power refers to the idle charging power, and the second tuning valve opening refers to the preset tuning valve opening corresponding to the idle charging power.

[0114] In a specific implementation, when the vehicle charging power is in the idle medium power charging state, the engine speed is between 1100 and 1200 rpm, and the tuning valve implements the preset value B (the second tuning valve opening).

[0115] Step A323: When the target charging power is a third charging power, determine the third tuning valve opening as the target tuning valve opening, the third charging power is greater than the second charging power, and the third tuning valve opening is greater than the second tuning valve opening.

[0116] It can be understood that the third charging power refers to the idle high-power charging, and the third charging power refers to the preset tuning valve opening corresponding to the idle high-power charging.

[0117] In a specific implementation, when the vehicle charging power is in idle high-power charging, the engine speed is between 1300 and 1400 rpm, and the tuning valve implements the preset value B (the second tuning valve opening).

[0118] This embodiment determines a target charging power based on the vehicle's remaining battery charge and electrical load when the target hybrid mode is idle charging mode; and determines a corresponding target tuning valve opening based on the target charging power. When the vehicle is in idle charging mode, the charging power is determined, and the corresponding tuning valve opening is derived. This allows the engine to be set to different speeds to accommodate different charging powers during idle charging, and the tuning valve opening is adjusted to suit the vehicle's overall state, achieving a balance between noise and backpressure.

[0119] For example, in order to help understand the implementation process of the tuning valve control method obtained by combining this embodiment with the above embodiment 1, please refer to Figure 5 , Figure 5 A simplified flow chart of the tuning valve control method is provided. Specifically, when the vehicle is in the low-pressure state, the engine is not running, and the tuning valve is 100% open to prevent water and other foreign matter from entering the exhaust pipe, which could lead to corrosion and sticking of the valve body and exhaust pipe. When the vehicle is in pure electric mode, the engine is not running, and the tuning valve is 100% open to prevent water and other foreign matter from entering the exhaust pipe, which could lead to corrosion and sticking of the valve body and exhaust pipe. When the vehicle is in hybrid mode, the vehicle is stationary and free of tire and wind noise. To improve NVH performance, the charging power is set to low, medium, or high, corresponding to different engine speeds, based on the battery SOC and power load. The tuning valve opening should be minimized to attenuate exhaust noise and enhance vehicle comfort. During idle low-power charging, the engine speed is low, set between 900 and 1000 rpm, and the tuning valve operates at preset value A. During idle medium-power charging, the engine speed is medium, set between 1100 and 1200 rpm, and the tuning valve operates at preset value B. During idle high-power charging, the engine speed is high, set between 1300 and 1400 rpm, and the tuning valve operates at preset value C. In extended-range mode, the engine is solely engaged in power generation. This setting is generally based on vehicle speed, typically below 80 km / h and above 140 km / h. In extended-range mode, the point is selected based on engine thermal efficiency. In low-speed extended-range mode, the engine speed is generally below 1800 rpm, with a narrow engine speed range. The tuning valve opening is preset value D. In high-speed extended-range mode, the engine speed is generally between 3000 and 4000 rpm, with a wide engine speed range. Below 3500 rpm, the tuning valve opening is preset value E to reduce noise. Above this point, the tuning valve opens 100% to reduce backpressure and maintain engine performance. When the vehicle is in direct drive mode, the engine and wheels are directly connected. To ensure linear noise and backpressure response, the tuning valve opening varies linearly with engine speed within a preset DE value. When the vehicle is submerged, the tuning valve opening is set to 0%, completely closed, to prevent wastewater from entering the exhaust system and clogging the catalyst. The PDCM continuously records and uploads the tuning valve feedback signal.
