[0050] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts should fall within the scope of protection of the present invention.

[0051] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0052] Figure 1 FIG. 1 is a flow chart of a first control method for reducing vehicle noise according to an embodiment of the present invention. Figure 1 As shown, the control method includes:

[0053] S10: Obtain vehicle load status, transmission gear position, torque change rate, and throttle change rate.

[0054] The vehicle's current load status can be obtained in real time after the vehicle is powered on. The vehicle's load status can be a factor affecting vehicle noise. The engine control unit can identify the vehicle's load and determine whether it is unloaded, fully loaded, or somewhere in between.

[0055] The gear position of the transmission may be the gear position of the current vehicle during driving, and different gear positions of the transmission may affect different parameters of noise regulation.

[0056] The throttle change rate can represent the speed of the throttle opening change, and the torque change rate can represent the speed of the torque change.

[0057] S11. Determine a torque change threshold and a throttle change threshold according to the vehicle load state and the gear position of the transmission.

[0058] Since different load conditions have different effects on noise, different transmission gears can affect noise regulation parameters such as speed and torque. Therefore, the torque change threshold and throttle change threshold are determined according to the vehicle load condition and transmission gear.

[0059] The torque change threshold represents the critical torque change threshold for noise suppression, and the throttle change threshold represents the critical throttle opening change for noise suppression. The torque change threshold and throttle change threshold vary depending on the vehicle load and transmission gear.

[0060] S12: When the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, a maximum speed control signal, a torque limit signal, a throttle filter signal and a smoke limit signal are output.

[0061] When the torque change rate is greater than the torque change threshold, it indicates a rapidly changing torque condition; when the throttle change rate is greater than the throttle change threshold, it indicates the driver is rapidly pressing the accelerator. Under these conditions, noise can easily increase rapidly. Therefore, a maximum speed control signal is output to control the maximum speed for the current transmission gear, a torque limit signal is output to limit torque, a throttle filter signal is output to adjust the throttle filter, thereby stabilizing the throttle signal to the engine control unit, and a smoke limit signal is output to adjust the fuel injection quantity, thereby controlling engine combustion and reducing noise.

[0062] For example, the engine control unit obtains the vehicle load status, gearbox gear, torque change rate and throttle change rate in real time. At this time, the vehicle is in an unloaded state and the gearbox gear is , determine the torque change threshold according to the vehicle load status and gearbox gear and throttle change threshold . Real-time judgment of whether the torque change rate is greater than , whether the throttle change threshold is greater than When the torque change rate is greater than the torque change threshold , when the throttle change rate is greater than the throttle change threshold , output the maximum speed control signal to the maximum speed Control and output torque limit signal to limit torque Control and output throttle filter signal to filter the throttle Control and output smoke limit signal to limit smoke density Take control.

[0063] It can be understood that the technical solution of the embodiment of the present invention only suppresses noise when the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, that is, when the torque is in a rapid change state and the throttle is in a rapid change state, it is considered that there is a risk of rapid noise increase at this time, so control is performed in terms of speed, torque, throttle filtering and smoke limitation to reduce the noise of the entire vehicle, and when the torque rapid change and throttle rapid change states are not met, noise control is not performed. Therefore, the technical solution of the embodiment of the present invention can not only ensure the power of the vehicle in the state of non-rapid torque change and rapid throttle change, but also suppress noise in the state of rapid torque change and rapid throttle change, thereby improving the comfort of the entire vehicle.

[0064] The technical solution of the embodiment of the present invention outputs a maximum speed control signal, a torque limit signal, a throttle filter signal and a smoke limit signal when the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, and controls noise in terms of maximum speed, throttle filtering, torque limit and smoke limit, thereby ensuring the vehicle's dynamic performance in the state of non-rapid torque change and rapid throttle change, and suppressing noise in the state of rapid torque change and rapid throttle change, thereby improving the comfort of the entire vehicle.

[0065] Based on the above embodiments, Figure 2 FIG. 1 is a flow chart of a second control method for reducing vehicle noise according to an embodiment of the present invention. Figure 2 As shown, the control method includes:

[0066] S20: Obtain vehicle load status, transmission gear position, torque change rate, and throttle change rate.

[0067] S21. Determine a torque change threshold and a throttle change threshold according to the vehicle load state and the gear position of the transmission.

[0068] S22: When the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, a maximum speed control signal, a torque limit signal, a throttle filter signal and a smoke limit signal are output.

[0069] S23 , obtaining the duration of outputting the maximum speed control signal, the torque limit signal, the throttle filter signal, and the smoke limit signal.

[0070] Among them, the output of the maximum speed control signal, torque limit signal, throttle filter signal and smoke limit signal is synchronized with the acquisition of duration, the purpose of which is to count the duration of outputting the maximum speed control signal, torque limit signal, throttle filter signal and smoke limit signal.

[0071] S24. When the duration reaches the preset time, stop outputting the maximum speed control signal, the torque limit signal, the throttle filter signal, and the smoke limit signal.

[0072] The preset time can be the system's set output signal duration. To suppress noise without unduly impacting power, a preset time can be set based on the vehicle's specific conditions. When the preset time is reached, the system stops outputting the maximum speed control signal, torque limit signal, throttle filter signal, and smoke limit signal, effectively halting vehicle noise control.

[0073] The technical solution of the embodiment of the present invention achieves the purpose of noise reduction by controlling vehicle noise within a preset time, while not affecting the vehicle's dynamics, meeting the driver's driving needs, and improving the comfort of the entire vehicle.

[0074] Based on the above embodiments, Figure 3 FIG. 1 is a flow chart of a third control method for reducing vehicle noise according to an embodiment of the present invention. Figure 3 As shown, the control method includes:

[0075] S30: Obtain vehicle load status, transmission gear position, torque change rate, and throttle change rate.

[0076] S31. Determine a torque change threshold and a throttle change threshold according to the vehicle load state and the gear position of the transmission.

[0077] S32: When the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, output a maximum speed control signal, a torque limit signal, a throttle filter signal, and a smoke limit signal.

[0078] S33: Obtain the duration of outputting the maximum speed control signal, the torque limit signal, the throttle filter signal, and the smoke limit signal.

[0079] S34. When the duration reaches the preset time, stop outputting the maximum speed control signal, the torque limit signal, the throttle filter signal, and the smoke limit signal.

[0080] S35: Obtain throttle opening parameters.

[0081] After the noise control is stopped, the throttle opening parameters are continued to be collected.

[0082] S36: When the throttle opening parameter is less than the preset opening parameter, continue to obtain the vehicle load status, transmission gear position, torque change rate, and throttle change rate.

[0083] S37. Determine a torque change threshold and a throttle change threshold according to the vehicle load state and the gear position of the transmission.

[0084] S38. When the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, a maximum speed control signal, a torque limit signal, a throttle filter signal and a smoke limit signal are output.

[0085] Among them, when the throttle opening parameter is less than the preset opening parameter, it means that the throttle opening has returned to a smaller opening state. At this time, the driver can continue to operate the throttle change rate and the torque change rate according to driving needs, so the vehicle load status, gearbox gear, torque change rate and throttle change rate continue to be obtained, and when the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, the noise control continues.

[0086] It is understandable that when the throttle opening parameter is less than the preset opening parameter, it indicates that the throttle opening has returned to a smaller state, and the noise control mode can be continued according to the driver's operation. However, when the throttle opening parameter is less than the preset opening parameter, even if the driver increases the torque change rate and the throttle change rate, the torque change rate will not be greater than the torque change threshold, and the throttle change rate will not be greater than the throttle change threshold. Therefore, it is not necessary to continue to obtain the vehicle load status, transmission gear, torque change rate, and throttle change rate. The technical solution of the embodiment of the present invention only performs noise suppression under the conditions of excessive throttle opening changes and excessive torque changes. Therefore, if the throttle opening changes significantly, it is necessary to ensure that the initial throttle opening is small, thereby increasing the real-time judgment of the throttle opening parameters.

[0087] The technical solution of the embodiment of the present invention ensures noise reduction during vehicle driving and improves vehicle comfort by collecting throttle opening parameters in real time after stopping noise control and continuing cyclic control when the throttle opening parameters are less than preset opening parameters.

[0088] Based on the above embodiments, Figure 4 FIG. 1 is a flow chart of a fourth control method for reducing vehicle noise according to an embodiment of the present invention. Figure 4 As shown, the control method includes:

[0089] S40: Obtain vehicle load status, transmission gear position, torque change rate, and throttle change rate.

[0090] S41. Determine a torque change threshold and a throttle change threshold according to the vehicle load state and the gear position of the transmission.

[0091] S42. When the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, obtain the real-time speed, real-time torque parameter and throttle opening parameter, gear-maximum speed relationship, gear-speed-torque limit relationship, gear-throttle opening-throttle filtering relationship, and gear-speed-smoke limit relationship.

[0092] in, Figure 5 The gear position-maximum speed relationship diagram provided by the embodiment of the present invention is a gear position-maximum speed relationship diagram. The gear position-maximum speed relationship can be a curve diagram of the gear position as the maximum speed changes. n Changes shown as Figure 5 ; Figure 6 The gear position-speed-torque limit relationship diagram provided by the embodiment of the present invention is a gear position-speed-torque limit relationship diagram. The gear position-speed-torque limit relationship can be a torque limit curve diagram that changes with the gear position and speed. n and real-time speed X n Changes shown as Figure 6 ; Figure 7The gear position-throttle opening-throttle filter relationship diagram provided by the embodiment of the present invention can be a throttle filter curve diagram that changes with the gear position and throttle opening. n and throttle opening parameter a n Changes shown as Figure 7 ; Figure 8 The gear position-speed-smoke density limit relationship diagram provided by the embodiment of the present invention is a gear position-speed-smoke density limit relationship diagram. The gear position-speed-smoke density limit relationship diagram can be a smoke density limit curve diagram that changes with gear position and speed. n and real-time speed X n The relationship between gear position and maximum speed, gear position and speed, torque limit, gear position and throttle opening and throttle filter, and gear position and speed can be obtained through pre-calibration.

[0093] S43. Output a maximum speed control signal based on the transmission gear position and the gear-maximum speed relationship; output a torque limit signal based on the transmission gear position, the real-time speed, and the gear-speed-torque limit relationship; output a throttle filter signal based on the transmission gear position, the throttle opening parameter, and the gear-throttle opening-throttle filter relationship; and output a smoke density limit signal based on the transmission gear position, the real-time speed, and the gear-speed-smoke density limit relationship.

[0094] Among them, a maximum speed control signal can be output based on the current transmission gear position combined with the gear position-maximum speed relationship to control the maximum speed in the current gear. A torque limit signal can be output based on the current transmission gear position, real-time speed, and the gear position-speed-torque limit relationship to limit the real-time torque parameter in the current gear. A throttle filter signal can be output based on the current transmission gear position, throttle opening parameter, and the gear position-throttle opening-throttle filter relationship to control the throttle filter in the current gear. A smoke limit signal can be output based on the current transmission gear position, real-time speed, and the gear position-speed-smoke limit relationship to control the throttle filter in the current gear.

[0095] Figure 9 is a noise control comparison diagram provided according to an embodiment of the present invention, such as Figure 9 As shown in the figure, after controlling the maximum speed, torque limit, throttle filtering and smoke control, the noise of the whole vehicle is reduced by 20%, achieving the purpose of noise suppression and improving the comfort of the whole vehicle.

[0096] Based on the above embodiments, Figure 10 FIG. 1 is a flow chart of a fifth control method for reducing vehicle noise according to an embodiment of the present invention. Figure 10 As shown, the control method includes:

[0097] S50: Obtain vehicle load status, transmission gear position, real-time torque parameters, and throttle change rate.

[0098] S51. Determine the torque change rate according to the real-time torque parameter.

[0099] S52: Determine a torque change threshold and a throttle change threshold according to the vehicle load state and the gear position of the transmission.

[0100] S53: When the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, output a maximum speed control signal, a torque limit signal, a throttle filter signal, and a smoke limit signal.

[0101] The torque change rate can be determined by obtaining the torque parameters in real time to measure the magnitude of the torque change per unit time.

[0102] Based on the above embodiments, Figure 11 FIG. 1 is a flow chart of a sixth method for reducing vehicle noise according to an embodiment of the present invention. Figure 11 As shown, the control method includes:

[0103] S60: Obtain vehicle load status, transmission gear position, real-time torque parameters, and throttle opening parameters.

[0104] S61. Determine a throttle change rate according to a throttle opening parameter.

[0105] The throttle change rate can be determined by obtaining the throttle opening parameter in real time to measure the change range of the throttle opening per unit time.

[0106] S62: Determine a torque change threshold and a throttle change threshold according to the vehicle load state and the gear position of the transmission.

[0107] S63: When the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, output a maximum speed control signal, a torque limit signal, a throttle filter signal, and a smoke limit signal.

[0108] The technical solution of the embodiment of the present invention ensures real-time acquisition of the throttle change rate and the torque change rate by determining the throttle change rate according to the throttle opening parameter and determining the torque change rate according to the real-time torque parameter.

[0109] Based on the above embodiments, Figure 12 FIG. 1 is a flow chart of a seventh method for reducing vehicle noise according to an embodiment of the present invention. Figure 12 As shown, the control method includes:

[0110] S70: When a vehicle power-on signal is received, the vehicle load status, transmission gear position, torque change rate, and throttle change rate are obtained.

[0111] Among them, the vehicle power-on signal can be the vehicle start-up signal. When the vehicle power-on signal is received, it means that the vehicle throttle opening is in the initial state. At this time, the vehicle load status, gearbox gear, torque change rate and throttle change rate are obtained in real time.

[0112] S71. Determine a torque change threshold and a throttle change threshold according to the vehicle load state and the transmission gear position.

[0113] S72: When the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold, output a maximum speed control signal, a torque limit signal, a throttle filter signal, and a smoke limit signal.

[0114] It is understandable that when the vehicle power-on signal is received, the default throttle opening is 0, so there is no need to obtain the throttle opening parameters. The torque change rate and throttle change rate are directly monitored to reduce the vehicle noise and improve the vehicle comfort.

[0115] Based on the same inventive concept, an embodiment of the present invention further provides a control device for reducing vehicle noise, which is used to execute a control method for reducing vehicle noise. The control device for reducing vehicle noise includes:

[0116] The parameter acquisition module 100 is used to obtain the vehicle load status, gearbox gear, torque change rate and throttle change rate;

[0117] The working condition judgment module 200 is used to determine the torque change threshold and the throttle change threshold according to the vehicle load state and the gear position of the transmission;

[0118] The noise control module 300 is configured to output a maximum speed control signal, a torque limit signal, a throttle filter signal, and a smoke limit signal when the torque change rate is greater than a torque change threshold and the throttle change rate is greater than a throttle change threshold.

[0119] Specifically, the parameter acquisition module 100 is first used to obtain the vehicle load status, transmission gear, torque change rate and throttle change rate; then the working condition judgment module 200 is used to determine the torque change threshold and throttle change threshold according to the vehicle load status and transmission gear; then the noise control module 300 is used to output the maximum speed control signal, torque limit signal, throttle filter signal and smoke limit signal when the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold.

[0120] The technical solution of the embodiment of the present invention utilizes a parameter acquisition module, an operating condition judgment module, and a noise control module to perform noise suppression, thereby ensuring the vehicle's dynamic performance when the torque is not changing rapidly and the throttle is changing rapidly, and can also suppress noise when the torque is changing rapidly and the throttle is changing rapidly, thereby improving the comfort of the entire vehicle.

[0121] Based on the same inventive concept, an embodiment of the present invention further provides a computer device, Figure 14 FIG. 1 is a schematic diagram of the structure of an electronic device for a control method for reducing vehicle noise according to an embodiment of the present invention.
