[0050] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] It should be noted that the terms "first", "second", etc. in the description, claims and above-mentioned drawings of the present invention are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, 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 "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0052] Figure 1 is a flowchart of the first method for controlling vehicle noise reduction according to an embodiment of the present invention. As Figure 1 shown, the control method includes:

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

[0054] Among them, after the vehicle is powered on, the current vehicle load status can be obtained in real time. The vehicle load status can be one of the factors affecting vehicle noise. The engine control unit can judge whether the vehicle is in an unloaded, fully loaded or partially loaded state by identifying the vehicle load.

[0055] Among them, the transmission gear can be the gear during the current vehicle driving, and different transmission gears affect different parameters for noise adjustment.

[0056] Among them, the throttle change rate can characterize the speed of change of the throttle opening, and the torque change rate can characterize the speed of change of the torque.

[0057] S11. Determine the torque change threshold and the throttle change threshold according to the vehicle load status and the transmission gear.

[0058] Since different vehicle load statuses have different effects on noise, and different transmission gears can affect parameters for noise adjustment, such as parameters like speed and torque, the torque change threshold and the throttle change threshold are determined according to the vehicle load status and the transmission gear.

[0059] Among them, the torque change threshold can characterize the critical value of torque change for noise suppression, and the throttle change threshold can characterize the critical value of throttle opening change for noise suppression. Under different vehicle load statuses and transmission gears, the torque change threshold and the throttle change threshold are different.

[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, output the maximum speed control signal, torque limit signal, throttle filter signal, and smoke limit signal.

[0061] Among them, when the torque change rate is greater than the torque change threshold, it indicates that the torque is in a rapid change working condition at this time; when the throttle change rate is greater than the throttle change threshold, it indicates that the driver is in a rapid throttle stepping working condition at this time. In the above working conditions, the noise is likely to increase rapidly. Therefore, at this time, output the maximum speed control signal to control the maximum speed under the current gearbox gear, output the torque limit signal for torque limitation, output the throttle filter signal to adjust the throttle filter, so that the throttle signal of the engine control unit is more stable, and output the smoke limit signal to adjust the fuel injection amount, thereby controlling the engine combustion and reducing the noise.

[0062] Exemplarily, 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 the throttle change threshold . Judge in real time whether the torque change rate is greater than , and whether the throttle change threshold is greater than . 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 the maximum speed control signal to control the maximum speed , output the torque limit signal to control the torque limitation , output the throttle filter signal to control the throttle filter , and output the smoke limit signal to control the smoke limit .

[0063] It can be understood that the technical solution of the embodiment of the present invention only suppresses the 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. Therefore, control is carried out in terms of speed, torque, throttle filter, and smoke limit to reduce the noise of the whole vehicle. When the torque does not change rapidly and the throttle does not change rapidly, no noise control is carried out. Therefore, the technical solution of the embodiment of the present invention can not only ensure the power performance of the vehicle when the torque and throttle do not change rapidly, but also suppress the noise when the torque and throttle change rapidly, improving the comfort of the whole vehicle.

[0064] In the technical solution of the embodiment of the present invention, 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 maximum speed control signal, the torque limit signal, the throttle filter signal, and the smoke limit signal are output, and the noise is controlled in terms of the maximum speed, throttle filtering, torque limit, and smoke limit, ensuring the power performance of the vehicle when the torque and throttle do not change rapidly, and suppressing the noise when the torque and throttle change rapidly, thus improving the overall vehicle comfort.

[0065] Based on the above embodiment, Figure 2 is a flowchart of the second control method for reducing the overall vehicle noise provided by the embodiment of the present invention. As Figure 2 shown, the control method includes:

[0066] S20. Obtain the vehicle load state, transmission gear, torque change rate, and throttle change rate.

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

[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, output the maximum speed control signal, the torque limit signal, the throttle filter signal, and the smoke limit signal.

[0069] S23. Obtain 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, the torque limit signal, the throttle filter signal, and the smoke limit signal and the acquisition of the duration are synchronized, and the purpose is to count the duration of outputting the maximum speed control signal, the torque limit signal, the throttle filter signal, and the 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] Among them, the preset time can be the output signal time set by the system. In order to suppress the noise without overly affecting the power performance, the preset time can be set according to the specific situation of the vehicle. 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, that is, stop controlling the vehicle noise.

[0073] In the technical solution of the embodiment of the present invention, by controlling the vehicle noise within the preset time, the purpose of noise reduction is achieved, and at the same time, the power performance of the vehicle is not affected, meeting the driving needs of the driver and improving the overall vehicle comfort.

[0074] Based on the above embodiments, Figure 3 is a flowchart of a third method for controlling vehicle noise provided according to an embodiment of the present invention. As Figure 3 shown, the control method includes:

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

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

[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 the maximum speed control signal, torque limit signal, throttle filter signal, and smoke limit signal.

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

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

[0080] S35. Obtain the throttle opening parameter.

[0081] Wherein, after stopping the noise control, continue to collect the throttle opening parameter.

[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 the torque change threshold and throttle change threshold according to the vehicle load status and transmission gear position.

[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, output the maximum speed control signal, torque limit signal, throttle filter signal, and smoke limit signal.

[0085] Wherein, when the throttle opening parameter is less than the preset opening parameter, it indicates 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 torque change rate to rise according to the driving requirements. Therefore, continue to obtain the vehicle load status, transmission gear position, torque change rate, and throttle change rate, 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, continue to control the noise.

[0086] It can be understood 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. At this time, according to the driver's operation, the vehicle can continue to enter the noise control working condition. 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, there will be no situation where the torque change rate is greater than the torque change threshold and the throttle change rate is greater than the throttle change threshold. Therefore, there is no need to continue to obtain the vehicle load state, 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 change and excessive torque change. Therefore, a large throttle opening change requires ensuring a small initial throttle opening, and accordingly, real-time judgment of the throttle opening parameter is increased.

[0087] The technical solution of the embodiment of the present invention, after stopping noise control, collects the throttle opening parameter in real time, and when the throttle opening parameter is less than the preset opening parameter, continues cyclic control to ensure noise reduction during the vehicle driving process and improve the vehicle comfort.

[0088] Based on the above embodiments, Figure 4 is a flowchart of the fourth vehicle noise reduction control method provided by the embodiment of the present invention, as Figure 4 shown, the control method includes:

[0089] S40. Obtain the vehicle load state, transmission gear, torque change rate, and throttle change rate.

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

[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, throttle opening parameter, gear - maximum speed relationship, gear - speed - torque limit relationship, gear - throttle opening - throttle filter relationship, and gear - speed - smoke limit relationship.

[0092] Among them, Figure 5 is a gear - maximum speed relationship diagram provided by the embodiment of the present invention. The gear - maximum speed relationship can be a curve graph of the maximum change with the gear. As the gear D n changes, it is shown as Figure 5 ; Figure 6 is a gear - speed - torque limit relationship diagram provided by the embodiment of the present invention. The gear - speed - torque limit relationship can be a torque limit curve graph that changes with the gear and speed. As the transmission gear D n and the real-time speed X n change, it is shown as Figure 6 ; Figure 7A gear-throttle opening-throttle filter relationship diagram provided according to an embodiment of the present invention. The gear-throttle opening-throttle filter relationship can be a throttle filter curve that changes with the gear and throttle opening. Along with the transmission gear D n and the throttle opening parameter a n The change is shown as Figure 7 ; Figure 8 A gear-rotational speed-smoke limit relationship diagram provided according to an embodiment of the present invention. The gear-rotational speed-smoke limit relationship can be a smoke limit curve that changes with the gear and rotational speed. Along with the transmission gear D n and the real-time rotational speed X n The change is shown in the figure. The gear-maximum rotational speed relationship, the gear-rotational speed-torque limit relationship, the gear-throttle opening-throttle filter relationship, and the gear-rotational speed-smoke limit relationship can be obtained through pre-calibration.

[0093] S43. Output a maximum rotational speed control signal according to the transmission gear and the gear-maximum rotational speed relationship, output a torque limit signal according to the transmission gear, the real-time rotational speed, and the gear-rotational speed-torque limit relationship, output a throttle filter signal according to the transmission gear, the throttle opening parameter, and the gear-throttle opening-throttle filter relationship, and output a smoke limit signal according to the transmission gear, the real-time rotational speed, and the gear-rotational speed-smoke limit relationship.

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

[0095] Figure 9 A noise control comparison diagram provided according to an embodiment of the present invention. As Figure 9 shown, through the control of the maximum rotational speed, torque limit, throttle filter, and smoke control, the vehicle noise reduction is 20%, achieving the purpose of noise suppression and improving the vehicle comfort.

[0096] Based on the above embodiments, Figure 10 A flowchart of the fifth control method for reducing vehicle noise provided according to an embodiment of the present invention. As Figure 10 shown, the control method includes:

[0097] S50. Obtain the vehicle load state, transmission gear, real-time torque parameter, and throttle change rate.

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

[0099] S52. Determine the torque change threshold and the throttle change threshold according to the vehicle load status and the transmission gear position.

[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 the maximum speed control signal, the torque limit signal, the throttle filter signal, and the smoke limit signal.

[0101] Among them, the torque change rate can be determined by obtaining the torque parameter in real time to measure the change amplitude of the torque per unit time.

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

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

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

[0105] Among them, the throttle change rate can be determined by obtaining the throttle opening parameter in real time to measure the change amplitude of the throttle opening per unit time.

[0106] S62. Determine the torque change threshold and the throttle change threshold according to the vehicle load status and the transmission gear position.

[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 the maximum speed control signal, the torque limit signal, the throttle filter signal, and the smoke limit signal.

[0108] The technical solution of the embodiment of the present invention ensures the 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 is a flowchart of the seventh control method for reducing the vehicle noise according to the embodiment of the present invention. As Figure 12 shown, the control method includes:

[0110] S70. When receiving the vehicle power-on signal, obtain the vehicle load status, the transmission gear position, the torque change rate, and the throttle change rate.

[0111] Among them, the on-vehicle power-on signal can be the vehicle startup signal. When the on-vehicle power-on signal is received, it indicates that the vehicle throttle opening is in the starting state at this time. At this time, the on-vehicle load status, transmission gear position, torque change rate, and throttle change rate are obtained in real time.

[0112] S71. Determine the torque change threshold and throttle change threshold according to the on-vehicle load status and 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 the maximum speed control signal, torque limit signal, throttle filter signal, and smoke limit signal.

[0114] It can be understood that when the on-vehicle power-on signal is received, the throttle opening is defaulted to 0 at this time. Therefore, there is no need to obtain the throttle opening parameter. Instead, directly monitor the torque change rate and throttle change rate to reduce the vehicle noise and improve the vehicle comfort.

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

[0116] A parameter acquisition module 100, which is used to acquire the on-vehicle load status, transmission gear position, torque change rate, and throttle change rate;

[0117] A working condition judgment module 200, which is used to determine the torque change threshold and throttle change threshold according to the on-vehicle load status and transmission gear position;

[0118] A noise control module 300, which 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.

[0119] Specifically, first use the parameter acquisition module 100 to acquire the on-vehicle load status, transmission gear position, torque change rate, and throttle change rate; then use the working condition judgment module 200 to determine the torque change threshold and throttle change threshold according to the on-vehicle load status and transmission gear position; then use the noise control module 300 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 uses the parameter acquisition module, working condition judgment module, and noise control module to suppress noise, ensuring the power performance of the vehicle in the state of non-rapid torque change and rapid throttle change, and can also suppress noise in the state of rapid torque change and rapid throttle change, improving the vehicle comfort.
