[0002] The noise inside the car directly affects the riding comfort and health of the passengers. With the development of the automobile industry, new energy vehicles are increasingly prominent in the market. Compared with traditional vehicles, the noise source in the front cabin of new energy vehicles has changed from the fuel engine to the compressor of the car air conditioner. In addition to cooling / heating the passenger compartment, the car air conditioner also needs to cool / heat the battery. In this way, the speed of the compressor will be very high, so the body vibration will also increase, the excitation frequency will also increase, and the overlap range with the body mode will increase. When the compressor is working stably, its speed is close to a certain mode of the body, which will cause vehicle resonance and reduce customer experience.

[0003] In the prior art, in order to avoid the resonance problem, the specific resonant speed is generally avoided in the controller software of the compressor itself, that is, when the vehicle controller requests the specific resonant speed, the compressor does not run at this speed, but runs at the speed avoided in advance, which is passive control. However, there are differences in the modes of vehicles, and therefore there are differences in the resonant speed ranges that match the whole vehicle. In the mass production of the whole vehicle, frequency avoidance according to the above scheme cannot take into account consistency, and there will still be problems of causing vehicle resonance after some models are avoided. Summary of the invention

[0006] The frequency avoidance method further includes: in response to a vehicle noise peak value being less than or equal to a preset target value, controlling the vehicle's compressor to maintain running at a current speed.

[0007] The vehicle is provided with a sound sensor, and the step of obtaining the noise peak inside the vehicle includes: collecting the noise inside the vehicle by using the sound sensor; and performing spectrum analysis on the noise to obtain the noise peak.

[0008] The step of obtaining the noise target setting value includes: obtaining a user instruction; and parsing the user instruction to obtain the noise target setting value.

[0009] Among them, before the step of obtaining the noise peak value inside the vehicle, the frequency avoidance method also includes: determining whether the vehicle's onboard air conditioner is in a working state; in response to the onboard air conditioner being in a working state, executing the step of obtaining the noise target setting value and obtaining the noise peak value inside the vehicle.

[0010] The step of adjusting the speed of the compressor of the vehicle to avoid frequency includes: obtaining a preset speed step; and adjusting the speed of the compressor based on the preset speed step to avoid the current speed of the compressor.

[0012] The preset speed step is greater than or equal to the minimum value of the compressor operating speed.

[0013] In order to solve the above technical problems, another technical solution adopted in the present application is: to provide a vehicle, the vehicle includes a processor and a memory connected to the processor, wherein program data is stored in the memory, and the processor executes the program data stored in the memory to execute the frequency avoidance method of the compressor to implement any of the above items.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The noise inside the car directly affects the riding comfort and health of the passengers. With the development of the automobile industry, new energy vehicles are increasingly prominent in the market. Compared with traditional vehicles, the noise source in the front cabin of new energy vehicles has changed from the fuel engine to the compressor of the car air conditioner. In addition to cooling / heating the passenger compartment, the car air conditioner also needs to cool / heat the battery. In this way, the speed of the compressor will be very high, so the body vibration will also increase, the excitation frequency will also increase, and the overlap range with the body mode will increase. When the compressor is working stably, its speed is close to a certain mode of the body, which will cause vehicle resonance and reduce customer experience.

[0027] In the prior art, in order to avoid the resonance problem, the specific resonant speed is generally avoided in the controller software of the compressor itself, that is, when the vehicle controller requests the specific resonant speed, the compressor does not run at this speed, but runs at the speed avoided in advance, which is passive control. However, there are differences in the modes of vehicles, and therefore there are differences in the resonant speed ranges that match the whole vehicle. In the mass production of the whole vehicle, frequency avoidance according to the above scheme cannot take into account consistency, and there will still be problems of causing vehicle resonance after some models are avoided.

[0028] For example, when the compressor runs at 2400rpm, there is a resonant roar inside the vehicle. At this time, the prior art uses the compressor itself to avoid it. That is, when the vehicle's processor requests the compressor of the car air conditioner to run at 2400rpm, the compressor runs at 2300rpm or 2500rpm. Although this solution of the prior art can also avoid the resonant speed, it is necessary to first identify the resonant bandwidth and lock the avoidance speed range. The speed range varies with the compressor. Therefore, as mentioned above, the prior art cannot take into account consistency when performing frequency avoidance.

[0029] For example, taking the air-conditioning compressor of a pure electric vehicle as an example, the air-conditioning compressor is installed on the sub-frame using a plastic secondary vibration isolation bracket. The modal frequencies of the compressor mode and the compressor bracket mode are shown in the following table:

[0030]

[0031]

[0032] Therefore, in the actual operation of the vehicle, the following problems will occur: 1. When the compressor runs at a speed of about 2000rpm, its compressor mode is excited, causing resonance in the car, ear pressure and steering wheel numbness; 2. When the compressor runs at a speed of about 6000rpm, the compressor bracket modal resonance causes roaring and shaking in the car. In order to solve the above problems, the existing technology sets multiple avoidance speeds in different speed ranges, and sets corresponding actual speeds for the avoidance speeds, as shown in the following table:

[0033]

[0034] However, due to the characteristics of rubber, the bushing stiffness has a bandwidth, which leads to differences in the mode of the compressor bracket when it is matched with the whole vehicle. As a result, there are differences in the resonant speed range of the matching vehicle. In the mass production of the whole vehicle, frequency avoidance according to the above scheme cannot take into account consistency, and some vehicles will still have resonance problems after avoidance.

[0035] In order to solve the above problems, the present application first proposes a frequency avoidance method for a compressor. Figure 1 , Figure 1 : is a flow chart of the first embodiment of the frequency avoidance method for the compressor of the present application. Figure 1 As shown, the frequency avoidance method of the compressor in this embodiment specifically includes steps S101 to S103:

[0036] Step S101: Obtain a noise target setting value and obtain a noise peak value inside the vehicle.

[0037] In this embodiment, an active avoidance method is adopted. First, the vehicle processor needs to obtain the noise target setting value, and obtain the noise peak value inside the vehicle through the sensor inside the vehicle. Among them, the noise target setting value is set by the driver, and different drivers can set different noise target setting values ​​based on their own conditions. For example, the noise target setting value can set a single frequency peak value, and different drivers can set it based on their own acceptability.

[0038] After the noise target setting value is set, the noise peak value inside the vehicle can be collected and obtained in real time, and the collected noise peak value can be sent to the vehicle's processor.

[0039] Step S102: Determine whether the noise peak value is greater than the noise target setting value.

[0040] After receiving the noise peak value, the vehicle's processor can compare the noise peak value with the noise target setting value to determine whether the noise peak value is greater than the noise target setting value.

[0041] If the noise peak value is greater than the noise target setting value, go to step S103; if the noise peak value is less than or equal to the noise target setting value, go to step S104.

[0042] Step S103: adjusting the rotation speed of the vehicle's compressor to avoid frequency fluctuations.

[0043] When the vehicle processor determines that the noise peak is greater than the noise target setting value, it is determined that the rotation speed of the vehicle compressor causes the vehicle resonance to exceed the driver's acceptance. Therefore, the vehicle processor needs to adjust the rotation speed of the vehicle compressor to avoid frequency. After adjusting the rotation speed of the vehicle compressor, steps S101 and S102 can be performed again. If the vehicle processor determines that the noise peak is still greater than the noise target setting value, the rotation speed of the vehicle compressor continues to be adjusted. Among them, when adjusting the rotation speed of the vehicle compressor, the rotation speed can be increased or decreased, and the adjustment method can be set based on actual conditions.

[0044] Step S104: Control the compressor of the vehicle to maintain the current speed.

[0045] If the noise peak is less than or equal to the noise target setting value, it is determined that the resonance of the vehicle caused by the current speed of the vehicle's compressor does not exceed the driver's acceptability. At this time, the vehicle's processor can control the vehicle's compressor to maintain the current speed.

[0046] Different from the prior art, the compressor frequency avoidance method of the present application includes: obtaining a noise target setting value and obtaining a noise peak value inside the vehicle; determining whether the noise peak value is greater than the noise target setting value; in response to the noise peak value being greater than the preset target value, adjusting the speed of the vehicle's compressor to avoid frequency. In the above manner, the compressor frequency avoidance method of the present application can actively avoid frequency based on a manually set noise target setting value, and can set the noise target setting value according to the vehicle and the person, which is more subjective, operable and applicable.

[0047] Optionally, the method for obtaining the noise peak value inside the vehicle is as follows: Figure 2 See Figure 2 , Figure 2 yes Figure 1 Schematic diagram of the flow chart of the first embodiment of step S101 in FIG. In this embodiment, the vehicle is provided with a sound sensor, and this embodiment can be performed as follows Figure 2 The steps shown implement the step of obtaining the noise peak inside the vehicle in step S101, specifically including steps S201 to S202:

[0048] Step S201: Collect the noise inside the vehicle using a sound sensor.

[0049] In this embodiment, a sound sensor is provided inside the vehicle, so the sound sensor inside the vehicle can be used to collect the noise generated by the resonance inside the vehicle due to the excitation of the compressor. The sound sensor in this embodiment can be set as a microphone, and in other embodiments, the sound sensor can also be set as other devices, which is not limited here.

[0050] Step S202: performing spectrum analysis on the noise to obtain a noise peak.

[0051] After collecting the noise inside the vehicle, the sound sensor or the vehicle's processor can perform spectrum analysis on the noise to obtain the noise peak inside the vehicle. Among them, noise spectrum analysis is a method of measuring and analyzing the spectral characteristics of noise signals. It decomposes the frequency of the noise signal into different frequency bands in order to analyze and understand the source and characteristics of the noise.

[0052] Optionally, the method for obtaining the noise target setting value is as follows: Figure 3 See Figure 3 , Figure 3 yes Figure 1 101 in the second embodiment. Figure 2 The steps shown implement the step of obtaining the noise target setting value in step S101, specifically including steps S301 to S302:

[0053] Step S301: Obtain user instructions.

[0054] In this embodiment, the driver may set the noise target setting value by sending a user instruction to the processor of the vehicle, that is, the processor of the vehicle may receive the user instruction sent by the user.

[0055] Step S302: Analyze the user instruction to obtain the noise target setting value.

[0056] After receiving the user's instruction, the vehicle's processor can parse the user's instruction to obtain the noise target setting value set by the driver based on his or her own acceptance.

[0057] Optionally, the method of adjusting the speed of the compressor of the vehicle to avoid frequency is as follows: Figure 4 See Figure 4 , Figure 4 yes Figure 1 Schematic diagram of the process of step S103 in an embodiment. This embodiment can be performed as follows Figure 4 The steps shown implement step S103, which specifically includes steps S401 to S402:

[0058] Step S401: Obtain a preset speed step.

[0059] When the noise peak is greater than the noise target setting value, the vehicle's processor needs to obtain a preset speed step when adjusting the speed of the vehicle's compressor to avoid frequency. The preset speed step is set to be greater than or equal to the minimum value of the compressor's operating speed. In this embodiment, the preset speed step of this embodiment can be set to 50-100rpm, and in other embodiments, the preset speed step can be set to other values, wherein the minimum value can be set to the minimum value of the compressor's operating speed, and the preset speed step can also be freely set by the driver, such as 100rpm, 200rpm, etc.

[0060] Step S402: adjusting the speed of the compressor based on a preset speed step to avoid the current speed of the compressor.

[0061] When the noise peak is greater than the noise target setting value, the vehicle's processor can increase or decrease the speed of the compressor based on the preset speed step after obtaining the preset speed step to avoid the current speed of the compressor.

[0062] Different from the prior art, increasing or decreasing the speed of the compressor based on a preset speed step can make the vehicle's control of the compressor speed more precise, and can reduce power consumption while avoiding frequency.

[0063] Optionally, in other embodiments, the method for adjusting the speed of the compressor based on the preset speed step is as follows: Figure 5 See Figure 5 , Figure 5 yes Figure 4 Schematic diagram of the process of step S402 in an embodiment. This embodiment can be performed as follows Figure 5 The steps shown are actually in step S402, which specifically include steps S501 to S504:

[0064] Step S501: Obtain the temperature difference between the interior of the vehicle and the external environment.

[0065] In this embodiment, when the vehicle processor adjusts the speed of the compressor based on the preset speed step, it can also perform corresponding control based on the temperature difference between the interior of the vehicle and the external environment. Specifically, the vehicle processor can first use the vehicle's temperature sensor to obtain the temperature difference between the interior of the vehicle and the external environment.

[0066] Step S502: Determine whether the temperature difference is greater than a preset temperature threshold.

[0067] After obtaining the temperature difference between the vehicle interior and the external environment, the vehicle processor can compare the temperature difference between the vehicle interior and the external environment with a preset temperature threshold. In this embodiment, the preset temperature threshold can be set based on actual conditions and is not limited here.

[0068] If the temperature difference is greater than the preset temperature threshold, go to step S503; if the temperature difference is less than or equal to the preset temperature threshold, go to step S504.

[0069] Step S503: increasing the speed of the compressor by an integer multiple of a preset speed step.

[0070] When the temperature difference is greater than the preset temperature threshold, the vehicle processor may increase the speed of the compressor by an integer multiple of the preset speed step when adjusting the speed of the compressor. That is, the vehicle processor may increase the current speed of the compressor by one preset speed step, or may increase the current speed of the compressor by multiple preset speed steps.

[0071] Step S504: reducing the speed of the compressor by an integer multiple of a preset speed step.

[0072] When the temperature difference is less than or equal to the preset temperature threshold, the vehicle processor may reduce the speed of the compressor by an integer multiple of the preset speed step when adjusting the speed of the compressor. That is, the vehicle processor may reduce the current speed of the compressor by one preset speed step, or may reduce the current speed of the compressor by multiple preset speed steps.

[0073] Different from the prior art, this embodiment adjusts the speed of the compressor by the temperature difference between the interior of the vehicle and the external environment, so as to achieve frequency avoidance without affecting the user's experience of using the car air conditioner, thereby further improving the user's comfort.

[0074] Optionally, based on the above embodiment, the present application further proposes a frequency avoidance method for a compressor, please refer to Figure 6 , Figure 6 1 is a flow chart of the second embodiment of the frequency avoidance method for the compressor of the present application. Figure 6 As shown, the frequency avoidance method of the compressor in this embodiment specifically includes steps S601 to S605:

[0075] Step S601: Determine whether the vehicle air conditioner is in working state.

[0076] In this embodiment, the vehicle's processor needs to determine whether the vehicle's air conditioner is in operation.

[0077] If the vehicle air conditioner is in working state, the process goes to step S602. That is, in this embodiment, the noise peak value inside the vehicle only needs to be collected and obtained when the vehicle air conditioner is working.

[0078] Step S602: Obtain a noise target setting value and obtain a noise peak value inside the vehicle.

[0079] Step S602 is consistent with step S101 and will not be described again.

[0080] Step S603: Determine whether the noise peak value is greater than the noise target setting value.

[0081] Step S603 is the same as step S102 and will not be described again.

[0082] If the noise peak value is greater than the noise target setting value, go to step S604; if the noise peak value is less than or equal to the noise target setting value, go to step S605.

[0083] Step S604: adjusting the speed of the vehicle's compressor to avoid frequency fluctuations.

[0084] Step S604 is consistent with step S103 and will not be described again.

[0085] Step S605: Control the vehicle's compressor to maintain the current speed.

[0086] Step S605 is consistent with step S104 and will not be described again.
