[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] Refer to Figure 1 , Figure 1 FIG. is a schematic structural diagram of an NVH control strategy generation device for a hardware operating environment related to the embodiment solution of the present invention.

Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0051] Those skilled in the art can understand that Figure 1 the structure shown in FIG. does not constitute a limitation on the NVH control strategy generation device, and may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements.

[0052] As Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a network communication module, a user interface module, and an NVH control strategy generation program.

[0053] In Figure 1In the NVH control strategy generation device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the NVH control strategy generation device of the present invention can be arranged in the NVH control strategy generation device. The NVH control strategy generation device calls the NVH control strategy generation program stored in the memory 1005 through the processor 1001 and executes the NVH control strategy generation method provided by the embodiments of the present invention.

[0054] An embodiment of the present invention provides an NVH control strategy generation method. Refer to Figure 2 , Figure 2 which is a schematic flowchart of the first embodiment of an NVH control strategy generation method of the present invention.

[0055] In this embodiment, the NVH control strategy generation method includes the following steps:

[0056] Step S10: Determine the target acquisition points on the vehicle to be tested and the operation strategy of the vehicle to be tested according to the vehicle information corresponding to the vehicle to be tested.

[0057] It should be understood that the execution subject of the method in this embodiment can be an NVH control strategy generation device with functions of data processing, network communication, and program operation, such as a workshop controller, or other devices or equipment that can implement the same or similar functions. Here, the above NVH control strategy generation device (hereinafter referred to as the strategy generation device) is taken as an example for description.

[0058] It should be noted that the vehicle to be tested can be a vehicle that needs to undergo NVH control testing. The above vehicle information can be the vehicle model information or identification information corresponding to the vehicle to be tested. The strategy generation device can determine the vehicle model or identification code of the vehicle to be tested according to the vehicle information of the vehicle to be tested, and can determine the structural information and part information of the vehicle to be tested according to the vehicle model and identification code of the vehicle to be tested. The above structural information can be the geometric structure composition information of the vehicle to be tested, and the above part information can be the relevant information of the parts installed on the vehicle to be tested. For example, the part information can include the information of the electric fan and the engine of the vehicle to be tested, etc.

[0059] The above target acquisition points can be the points on the vehicle to be tested for collecting NVH information. The target acquisition points can include noise acquisition points and vibration acquisition points. For example, the noise acquisition points can be at positions such as the near field of the engine room electric fan, the right ear of the driver, and the middle of the back row, and the vibration acquisition points can be at positions such as the center of the electric fan, the installation point of the electric fan, the seat rail, and the steering wheel. The above operation strategy can be the strategy for the strategy generation device to control the operation of the vehicle to be tested. For example, the operation strategy can include the engine operation strategy and the electric fan operation strategy, etc.

[0060] For example, the policy generation device sets noise acquisition points at the front, rear, left, right, and above of the vehicle body according to the vehicle information of the vehicle to be tested, and sets a noise acquisition point at the center of the fan blade and the edge of the fan frame of the electric fan respectively.

[0061] It should be understood that in order to accurately simulate the operation of the vehicle to be tested and obtain more accurate NVH information, the policy generation device in this embodiment determines the identification code and vehicle model of the vehicle to be tested according to the vehicle information corresponding to the vehicle to be tested, determines the structural information and part information of the vehicle to be tested, sets the target acquisition points of the vehicle to be tested according to the structural information, and determines the operation strategy of the vehicle to be tested according to the part information, realizing the simulated operation of the vehicle to be tested, and thus accurately collecting the NVH information when the vehicle to be tested is running.

[0062] In a specific implementation, the policy generation device determines the identification code and vehicle model of the vehicle to be tested according to the vehicle information corresponding to the vehicle to be tested, determines the structural information and part information of the vehicle to be tested, sets the target noise acquisition points and target vibration acquisition points of the vehicle to be tested according to the structural information, determines the engine information and electric fan information of the vehicle to be tested according to the part information, and determines the operation strategy of the vehicle according to the engine information and electric fan information.

[0063] Step S20: Control the operation of the vehicle to be tested according to the operation strategy, and collect the current NVH information of the target acquisition points during the operation process.

[0064] It should be noted that the current NVH information may be the real-time NVH information during the operation of the vehicle to be tested. The policy generation device can determine the current NVH information of the vehicle to be tested by obtaining the noise information and vibration information of the target acquisition points in real time, where the current NVH information may include current noise information, current vibration information, etc.

[0065] It should be understood that in order to effectively avoid inaccurate NVH information collected and improve the accuracy of the test, the policy generation device in this embodiment controls the operation of the engine and electric fan of the vehicle to be tested according to the operation strategy, and collects the current noise information and current vibration information of the target acquisition points on the vehicle to be tested in real time.

[0066] Step S30: Obtain the target NVH information that meets the preset conditions in the current NVH information, and determine the target vehicle operation information corresponding to the target NVH information.

[0067] It should be noted that the preset conditions may be vibration requirements and noise requirement conditions set in advance. For example, the preset conditions may be that the noise is lower than 60 decibels, etc. The above-mentioned target vehicle operation information may be the vehicle operation information when the NVH information of the vehicle to be tested is the target NVH information.

[0068] For example, the policy generation device obtains the current NVH information of the vehicle to be tested as information A, information B, information C, and information D, where the vehicle operation information corresponding to information A, information B, information C, and information D is operation information W, operation information X, operation information Y, and operation information Z, respectively; obtains the target NVH information that meets the preset conditions in the current NVH information as information B and information C, and determines the target vehicle operation information corresponding to the above target NVH information as operation information X and operation information Y.

[0069] Step S40: Generate the NVH control policy for the vehicle to be tested according to the target vehicle operation information.

[0070] It should be noted that the NVH control policy can be a policy for controlling the vehicle to be tested to meet the preset conditions. For example, the NVH control policy may include an electric fan control policy and an engine control policy.

[0071] It should be understood that, in order to improve the NVH performance of the vehicle to be tested and reduce the noise and vibration effects during the actual operation of the vehicle to be tested, the policy generation device in this embodiment generates the NVH control policy for the vehicle to be tested according to the target engine operation information and the electric fan operation information in the target vehicle operation information. Thus, during the operation of the vehicle to be tested, the engine and the electric fan of the vehicle to be tested are controlled according to the NVH control policy, effectively reducing the noise and vibration effects, and thus improving the NVH performance of the vehicle to be tested.

[0072] For example, when the policy generation device determines that the engine speed of the vehicle to be tested is 1500 rpm and the electric fan speed is 1000 rpm according to the target vehicle operation information, the NVH performance of the vehicle to be tested is relatively high. The NVH control policy for the vehicle to be tested is generated according to the target vehicle operation information, so as to control the electric fan speed to be 1000 rpm when the engine speed of the vehicle to be tested is 1500 rpm according to the NVH control policy, thereby improving the NVH performance of the vehicle to be tested.

[0073] In this embodiment, the target acquisition points on the vehicle to be tested and the operation strategy of the vehicle to be tested are determined according to the vehicle information corresponding to the vehicle to be tested. The vehicle to be tested is controlled to run according to the operation strategy, and the current NVH information of the target acquisition points during the running process is collected. The target NVH information that meets the preset conditions is obtained from the current NVH information, and the target vehicle operation information corresponding to the target NVH information is determined. An NVH control strategy for the vehicle to be tested is generated according to the target vehicle operation information. Since the present invention controls the vehicle to be tested to run according to the vehicle information and collects the current NVH information of the target acquisition points during the running process, the accuracy of NVH information collection is ensured. Then, the current NVH information is screened to obtain the target NVH information that meets the preset conditions in the current NVH information and the target vehicle operation information corresponding to the target NVH information. Then, an NVH control strategy is generated according to the target vehicle operation information, thereby realizing the accurate control of vehicle operation and improving the NVH performance of the vehicle.

[0074] Reference Figure 3 , Figure 3 is a schematic flowchart of the second embodiment of a method for generating an NVH control strategy according to the present invention.

[0075] Based on the above first embodiment, in this embodiment, step S30 includes:

[0076] Step S301: Obtain the current vehicle operation information corresponding to the current NVH information.

[0077] It should be noted that the current vehicle operation information may be the vehicle operation information when the NVH information of the vehicle to be tested is the current NVH information. For example, when the current NVH information of the vehicle to be tested is 50 dB noise, the engine speed is 850 rpm and the electric fan speed is 500 rpm; when the current NVH information is 70 dB noise, the engine speed is 1800 rpm and the electric fan speed is 2000 rpm.

[0078] Step S302: Generate a MAP graph according to the current vehicle operation information and the current NVH information.

[0079] It should be noted that the MAP graph may be a contour graph composed of the current vehicle operation information and the current NVH information. The strategy generation device can generate a MAP graph to intuitively display the change of the current NVH information and the current vehicle operation information corresponding to the current NVH information, so as to effectively determine the vehicle operation information when the NVH performance is better.

[0080] Step S303: Determine the target NVH information that meets the preset conditions in the current NVH information, and determine the target vehicle operation information corresponding to the target NVH information.

[0081] It should be noted that the preset conditions can be pre-set vibration requirements and noise requirement conditions. For example, the preset conditions can be that the noise needs to be lower than 70 decibels, the vibration needs to be lower than 100 mm, etc. The above-mentioned target vehicle operation information can be the vehicle operation information when the NVH information of the vehicle to be tested is the target NVH information.

[0082] It should be understood that in order to accurately determine the NVH information that meets the preset conditions in the currently collected NVH information, the strategy generation device in this embodiment determines the points that meet the preset conditions in the MAP diagram as the target NVH information that meets the preset conditions, and determines the target vehicle operation information corresponding to the target NVH information, so as to accurately and quickly determine the target vehicle operation information and improve the efficiency of generating the NVH control strategy.

[0083] Furthermore, since there may be various operating conditions during the actual operation of the vehicle to be tested, in order to give priority to ensuring the driving experience and riding experience of vehicle passengers, the above-mentioned step S303 may include:

[0084] Step S3031: Determine the candidate NVH information that meets the preset conditions in the currently collected NVH information according to the MAP diagram;

[0085] Step S3032: Obtain the acquisition weight corresponding to the target acquisition point;

[0086] Step S3033: Determine the target NVH information in the candidate NVH information according to the acquisition weight corresponding to the target acquisition point, and determine the target vehicle operation information corresponding to the target NVH information.

[0087] It should be noted that the candidate NVH information can be the NVH information that meets the preset conditions, and the candidate NVH information can be one or more. Since there may be multiple candidate NVH information that meet the preset conditions in the actual acquisition process, it is necessary to screen the candidate NVH information that meets the preset conditions.

[0088] The above-mentioned acquisition weight can be the weight of the influence of each target acquisition point on the vehicle to be tested on the driver or passenger. The influence of each target acquisition point on the vehicle to be tested on the driver or passenger is different. For example, the vibration at the steering wheel position has a greater impact on the driver, and the vibration at the door position has a smaller impact on the driver. Therefore, the strategy generation device determines the acquisition weight of each target acquisition point to screen the candidate NVH information.

[0089] In a specific implementation, for example, the policy generation device determines that the candidate NVH information in the current NVH information that meets the preset conditions is Information A, Information B, Information C, and Information D according to the MAP diagram, and the target acquisition points are Point X and Point Y, where the acquisition weight of Point X is 0.7 and the acquisition weight of Point Y is 0.3; in Information A, the influence on Point X is small and the influence on Y is large, in Information B, the influence on Point X is large and the influence on Y is small, in Information C, the influence on Point X is large and the influence on Y is large, and in Information D, the influence on Point X is large and the influence on Y is large. Therefore, Information A is determined as the target NVH information.

[0090] Further, in order to more accurately screen the candidate NVH information to improve the NVH performance of the vehicle to be tested, step S3033 above may include:

[0091] Obtain the fuel consumption information corresponding to the candidate NVH information;

[0092] Generate a screening condition according to the fuel consumption information and the acquisition weight corresponding to the target acquisition point;

[0093] Screen the candidate NVH information to obtain the target NVH information that meets the screening condition in the candidate NVH information, and determine the target vehicle operation information corresponding to the target NVH information.

[0094] It should be noted that the fuel consumption information may be the fuel consumption of the vehicle to be tested when the NVH information of the vehicle to be tested is the candidate NVH information, and the above screening condition may be the condition for screening the candidate NVH information.

[0095] It should be understood that, in order to more accurately screen the candidate NVH information to improve the NVH performance of the vehicle to be tested, the policy generation device in this embodiment obtains the fuel consumption information corresponding to the candidate NVH information, generates a screening condition according to the fuel consumption information and the acquisition weight corresponding to the target acquisition point, screens the candidate NVH information, obtains the target NVH information that meets the screening condition in the candidate NVH information, and determines the target vehicle operation information corresponding to the target NVH information, thereby realizing the effective screening of the candidate NVH information, obtaining a better target NVH information, and effectively improving the accuracy of the NVH control strategy.

[0096] In this embodiment, the current vehicle operation information corresponding to the current NVH information is obtained, a MAP graph is generated based on the current vehicle operation information and the current NVH information, target NVH information that meets a preset condition in the current NVH information is determined according to the MAP graph, and target vehicle operation information corresponding to the target NVH information is determined; since the present invention obtains the current vehicle operation information corresponding to the current NVH information, and then generates a MAP graph based on the obtained current vehicle operation information and current NVH information, thereby effectively reflecting the operation conditions and NVH change conditions of the vehicle to be tested during operation, determining the target NVH information that meets the preset condition in the current NVH information according to the MAP graph, and determining the target vehicle operation information corresponding to the target NVH information, thereby accurately determining the target NVH information that meets the preset condition and the target vehicle operation information corresponding to the target NVH information, thus ensuring the accuracy of the NVH control strategy.

[0097] Reference Figure 4 , Figure 4 is a schematic flowchart of the third embodiment of a method for generating an NVH control strategy according to the present invention.

[0098] Based on the above first embodiment, in this embodiment, the vehicle information includes performance information and structural information, and the step S10 includes:

[0099] Step S101: Determine each candidate acquisition point on the vehicle to be tested according to the structural information corresponding to the vehicle to be tested, and the acquisition weight corresponding to each candidate acquisition point.

[0100] It should be noted that the structural information may be the body geometric structure information of the vehicle to be tested, and the above-mentioned candidate acquisition points may be acquisition points on the vehicle to be tested where NVH information can be collected. In order to improve the accuracy of acquisition, the strategy generation device determines the acquisition weight corresponding to each candidate acquisition point to screen each candidate acquisition point.

[0101] It should be understood that, in order to accurately determine the acquisition points on the vehicle to be tested where NVH information needs to be collected, the strategy review device in this embodiment determines each candidate acquisition point on the vehicle to be tested according to the structural information corresponding to the vehicle to be tested, and the acquisition weight corresponding to each candidate acquisition point, thereby effectively determining the NVH influence degree of each candidate acquisition point.

[0102] Further, in order to accurately determine the acquisition weight to improve the accuracy of acquisition point selection, the above step S101 may include:

[0103] Step S1011: Determine each candidate acquisition point on the vehicle to be tested, as well as the cockpit position information and component position information of the vehicle to be tested according to the structure information corresponding to the vehicle to be tested, where the component position information includes the radiator fan position information and the steering wheel position information;

[0104] Step S1012: Determine the acquisition weight corresponding to each candidate acquisition point according to the cockpit position information and the component position information.

[0105] It should be noted that the cockpit position information may be the seat position information, seat distribution information, and cockpit space distribution information inside the cockpit of the vehicle to be tested. The above component position information may be the position distribution information of each component inside the vehicle to be tested.

[0106] Step S102: Determine the target acquisition points that meet the preset acquisition conditions among each candidate acquisition point according to the acquisition weight corresponding to each candidate acquisition point, where the target acquisition points include noise target acquisition points and vibration target acquisition points.

[0107] It should be noted that the preset acquisition conditions may be the screening conditions for screening candidate acquisition points. For example, the preset acquisition conditions may be that the acquisition weight needs to exceed 0.15, etc.

[0108] For example, the strategy generation device determines that the candidate acquisition points on the vehicle to be tested are A, B, and C according to the structure information, and the acquisition weights corresponding to each candidate acquisition point are 0.1, 0.3, and 0.6 respectively. The candidate acquisition points are screened according to the preset acquisition conditions, where the preset acquisition conditions are that the acquisition weight needs to exceed 0.25. Therefore, it is determined that the target acquisition points are B and C.

[0109] Step S103: Determine the operation strategy of the vehicle to be tested according to the performance information corresponding to the vehicle to be tested.

[0110] It should be noted that the performance information may be the engine performance information or the radiator fan performance information of the vehicle to be tested. The above engine performance information may be the engine speed range, and the above radiator fan performance information may be the radiator fan speed range.

[0111] Further, in order to accurately control the operation of the vehicle to be tested to simulate the working conditions of the actual operation process of the vehicle to be tested, the above step S103 may include:

[0112] Step S1031: Determine the engine performance information and the radiator fan performance information according to the performance information corresponding to the vehicle to be tested;

[0113] Step S1032: Determine the engine control strategy according to the engine performance information;

[0114] Step S1033: Determine the electronic fan control strategy according to the performance information of the electronic fan;

[0115] Step S1034: Determine the operation strategy of the vehicle to be tested according to the engine control strategy and the electronic fan control strategy.

[0116] It should be noted that the engine performance information may include the rotational speed performance information, power performance information, duty cycle performance information, etc. of the engine.
