[0002] With the rapid development of automobile electrification, the proportion of new energy vehicles continues to increase. For new energy vehicles, there is no engine noise masking in some or all operating conditions, and the noise of electrical components is more prominent. The air conditioning heater water pump is an important source of noise in the heating condition of new energy vehicles. When the whole vehicle is heated, the water heated by the PTC (Positive Temperature Coefficient) needs to be transferred to the inside of the air conditioning box through the heater water pump for heat exchange. The working noise of the vehicle's heater water pump is related to the noise of the heater water pump itself, as well as the layout position of the heater water pump and the sound insulation and vibration isolation characteristics of the vehicle. Generally speaking, the use of low-noise heater water pumps and improving the sound insulation and vibration isolation performance of the vehicle often leads to an increase in costs, and the layout position of the heater water pump is constrained by the layout space of the vehicle.

[0024] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The following describes in detail the noise control method, device, heater water pump, and vehicle of an air conditioner heater water pump according to embodiments of the present invention with reference to the accompanying drawings.

[0026] In some embodiments, automobile manufacturers usually start from the selection of water pumps and the optimization of sound insulation and vibration isolation to achieve noise control of heater water pumps, but they are often constrained by cost, layout space and cycle. The formulation of heater water pump control strategy is mainly considered from the perspective of maximum heating, and is not constrained from the NVH (Noise Vibration Harshness) performance of the whole vehicle. The heater water pump of new energy vehicles is an electric water pump, which generally uses PWM (Pulse Width Modulation) duty cycle to control its operating speed. The higher the duty cycle, the higher the speed, and generally speaking, the greater the noise. When the vehicle air conditioning is heating and the blower gear is low, the working noise of the blower is small. At this time, if the water pump works at a high duty cycle, the working noise of the water pump is easily perceived, affecting user comfort. In addition, when the blower gear is low, the heat that can be brought out through the air outlet is limited, and the high duty cycle of the water pump does not improve the heating effect much.

[0027] Based on this, this application obtains the working noise of the heater water pump at each duty cycle of the heater water pump in the whole vehicle state and the working noise of the blower at each gear. During the operation of the heater water pump, according to the current blower gear and noise requirements, the heater water pump is controlled to operate at different duty cycles, and the masking effect of the working noise of the blower on the working noise of the heater water pump is fully utilized, which can maximize the comfort in the vehicle without increasing hardware costs and cycles.

[0028] In some embodiments, a vehicle is placed in a semi-anechoic chamber, a noise sensor is installed in the vehicle, specifically at the right ear of the driver (the right ear of the driver is the noise measurement point), and the sensor is connected to a data acquisition system, which is connected to a test computer, a debugging device and a computer to test the working noise of the blower at each gear when the blower is running alone. In the embodiment of the present invention, the blower includes 7 gears, gear 1 is the lowest working gear, and gear 7 is the highest working gear. This is not intended to limit the present invention.

[0029] Exemplarily, the vehicle is powered on, doors and windows are closed, the blower is turned on alone, a noise sensor is used to test the working noise of the blower at various gears, and a two-dimensional mapping table of the blower gear and the working noise is recorded. The two-dimensional mapping table is shown in Table 1, including multiple blower gears and the working noise corresponding to each blower gear.

[0030] Table 1

[0031] Gear 1st gear 2nd gear 3rd gear 4 gears 5 gears 6 gears 7 gears Noise dB(A) 35 39.4 44.1 48.5 53 57.6 62

[0032] Furthermore, the warm air water pump is connected externally through a voltage-stabilized power supply and a signal generator, the output voltage of the voltage-stabilized power supply and the output signal of the signal generator are debugged, the warm air water pump is controlled to operate within the full duty cycle range, and the above-mentioned noise sensor is used to test the working noise of the warm air water pump when it operates alone at various duty cycles.

[0033] For example, the vehicle is powered on, doors and windows are closed, and a control signal from a signal generator is used to control the heater pump to operate independently at a corresponding duty cycle. The noise sensor is used to test the operating noise of the heater pump at each duty cycle when the heater pump operates independently, and a mapping curve between the heater pump operating duty cycle and the operating noise is drawn. The curve is as follows: Figure 1 It should be noted that the operation of the heater water pump can also be controlled by issuing instructions from the vehicle VCU (Vehicle Control Unit), and the specific control method is not specifically limited here.

[0034] Figure 2 Flow chart of a noise control method for an air conditioner heater water pump according to some embodiments of the present invention. Figure 2 The noise control method of the air conditioner heater water pump of the embodiment of the present application may include the following steps:

[0035] S110, when the air conditioner is in heating operation, obtaining an operating gear and noise requirement of the blower.

[0036] Specifically, during vehicle operation, the user can control the vehicle air conditioner to operate in heating mode by rotating the blower gear knob to the desired gear and determine the operating gear of the blower. For example, rotating the blower gear knob clockwise to gear N can control the vehicle air conditioner to operate in heating mode and determine the operating gear of the blower to gear N.

[0037] The noise requirement refers to the condition that the working noise of the blower can mask the working noise of the heater water pump. For example, if the noise requirement is met, it can be determined that the working noise of the blower can mask the working noise of the heater water pump; if the noise requirement is not met, it can be determined that the working noise of the blower cannot mask the working noise of the heater water pump.

[0038] S120: determining a target operating duty cycle of the heater water pump according to the operating gear and noise requirement of the blower.

[0039] Specifically, after obtaining the operating gear of the blower, the operating noise of the blower can be determined according to the operating gear of the blower. For example, the operating noise of the blower can be determined by querying a two-dimensional mapping table of the blower gear and the operating noise according to the operating gear of the blower (for example, Table 1). After determining the operating noise of the blower, the operating noise limit of the warm air water pump can be determined according to the noise requirement. In other words, if the operating noise of the warm air water pump is less than or equal to its noise limit, then the operating noise of the blower can mask the operating noise of the warm air water pump. After determining the operating noise limit of the warm air water pump, the target operating duty cycle of the warm air water pump can be determined according to the operating noise limit of the warm air water pump. For example, the mapping curve of the operating duty cycle of the warm air water pump and the operating noise can be queried according to the operating noise limit of the warm air water pump (for example, Figure 1 )Determine the target operating duty cycle of the heater water pump.

[0040] S130, controlling the heater water pump according to the target operation duty cycle.

[0041] Specifically, the heater water pump is controlled to operate at a target duty cycle, and the operating noise of the blower can mask the operating noise of the heater water pump. It should be noted that the target duty cycle is the maximum duty cycle of the heater water pump allowed to mask the operating noise of the heater water pump under the current blower gear. That is to say, if the duty cycle of the heater water pump is less than or equal to the target duty cycle, the operating noise of the heater water pump can be masked by the operating noise of the blower.

[0042] The control method of the present invention determines the target operating duty cycle of the heater water pump according to the operating gear and noise requirement of the blower, and can use the operating noise of the blower in the air conditioning heating mode to mask the operating noise of the air conditioning heater water pump. There is no need to optimize related hardware such as sound insulation and vibration isolation, thereby reducing the perception of the passengers in the car to the operating noise of the air conditioning heater water pump and improving comfort without increasing costs or changing the hardware structure.

[0043] In some embodiments, a target operating duty cycle of the heater water pump is determined based on the operating gear and noise requirement of the blower, including: when the operating gear of the blower does not exceed a preset gear, determining the corresponding working noise based on the operating gear of the blower; determining the working noise limit of the heater water pump based on the working noise corresponding to the operating gear of the blower and the noise requirement; and determining the target operating duty cycle of the heater water pump based on the working noise limit of the heater water pump.

[0044] Specifically, when the vehicle air conditioner is running in heating mode, while considering using the working noise of the blower to mask the working noise of the heater water pump, the maximum heating demand of the vehicle air conditioner must also be considered. Therefore, it is also necessary to determine whether the operating gear of the blower exceeds the preset gear. For example, if the operating gear of the blower does not exceed the preset gear, the target operating duty cycle of the heater water pump must be determined according to the operating gear of the blower and the noise requirement, so that the working noise of the blower can mask the working noise of the heater water pump; if the operating gear of the blower exceeds the preset gear, the maximum heating demand of the vehicle air conditioner must be met, and there is no need to consider the masking problem of the working noise of the heater water pump. Among them, the preset gear can be determined according to the actual situation. In the embodiment of the present invention, the preset gear is gear 6 as an example for explanation, but it is not used as a limit value for the present invention.

[0045] For example, assuming that the operating gear of the blower is gear 1, and gear 1 does not exceed gear 6, it can be determined by querying Table 1 that the working noise corresponding to gear 1 is 35dB(A). In order to make the working noise of the blower mask the working noise of the heater water pump, it can be determined that the working noise limit of the heater water pump is 25dB(A). That is to say, if the working noise of the heater water pump is less than or equal to 25dB(A), the working noise of the blower can mask the working noise of the heater water pump. Then, according to the working noise limit of the heater water pump 25dB(A), by querying Figure 1 The target operation duty cycle of the heater water pump may be determined to be 45%, that is, if the operation duty cycle of the heater water pump is less than or equal to 45%, the operation noise of the blower can mask the operation noise of the heater water pump.

[0046] In some embodiments, the above method also includes: obtaining the target minimum operating duty cycle of the warm air water pump corresponding to when the air conditioner meets the preset maximum heating demand; when the operating gear of the blower exceeds the preset gear, the target operating duty cycle of the warm air water pump is greater than or equal to the target minimum operating duty cycle.

[0047] Specifically, if the blower's operating gear exceeds the preset gear, for example, the blower's operating gear is gear 7, indicating that the maximum heating demand of the vehicle air conditioner needs to be met at this time, then it is necessary to ensure that the target operating duty cycle of the warm air water pump is greater than or equal to the target minimum operating duty cycle of the warm air water pump corresponding to the preset maximum heating demand of the air conditioner. Among them, the target minimum operating duty cycle of the warm air water pump can be obtained based on the vehicle's maximum heating experiment. For example, the target minimum operating duty cycle of the warm air water pump can be 80%, and no specific limit is given here.

[0048] In this way, while meeting the heating needs, the passengers' perception of the working noise of the heater pump can be reduced, thereby improving riding comfort.

[0049] In some embodiments, the working noise limit of the warm air water pump is determined according to the working noise corresponding to the running gear of the blower and the noise requirement, including: determining the noise reduction threshold according to the noise requirement; determining the working noise limit of the warm air water pump according to the difference between the working noise corresponding to the running gear of the blower and the noise reduction threshold. The noise reduction threshold can be determined according to actual conditions, for example, the noise reduction threshold can be 10dB(A), and no specific limit is given here.

[0050] Specifically, the noise requirement refers to the difference between the operating noise of the heater pump and the operating noise of the blower. That is to say, if the operating noise of the heater pump is lower than the operating noise of the blower by more than the noise reduction threshold, it means that the noise requirement is met, and it can be determined that the operating noise of the blower can mask the operating noise of the heater pump. Therefore, after determining the operating noise of the blower, the operating noise limit of the heater pump can be determined by calculating the difference between the operating noise of the blower and the noise reduction threshold.

[0051] For example, assuming that the operating noise of the blower is 35dB(A) and the noise reduction threshold is 10dB(A), then the operating noise limit of the heater water pump is 25dB(A).

[0052] In some embodiments, the target operating duty cycle corresponding to each working gear of the blower can be determined by the above method, and a two-dimensional mapping table of the blower gear and the target operating duty cycle can be formed. The target operating duty cycle can be determined by querying the two-dimensional mapping table.

[0053] Exemplarily, a two-dimensional mapping table of blower gear and target operating duty cycle is shown in Table 2, including multiple blower gears and the target operating duty cycle of the heater water pump corresponding to each blower gear. The heater water pump can be controlled to operate according to the target operating duty cycle in Table 2 according to the current blower gear.

[0054] Table 2

[0055]

[0056] It should be noted that, referring to Table 2, if the target minimum operating duty cycle of the heater water pump is determined to be 80% based on the maximum heating test of the whole vehicle, the maximum heating performance requirement can be met. However, when the gear of the blower is at gear 5 and above, even at the highest speed of the heater water pump (≥90% duty cycle), the operating noise of the heater water pump still meets the noise requirement, that is, the operating noise of the heater water pump can still be masked by the operating noise of the blower. Therefore, when the gear of the blower is gear 5 and above, there is no restriction on the duty cycle of the heater water pump.

[0057] In some embodiments, the above method also includes: when receiving a heating start command of the air conditioner, first controlling the blower to run for a first preset time, and then controlling the heater water pump to run, wherein the first preset time is determined according to the speed increase of the blower.

[0058] In some embodiments, the above method also includes: when receiving a heating stop command from the air conditioner, first controlling the warm air water pump to stop running for a second preset time, and then controlling the blower to stop running, wherein the second preset time is determined according to the deceleration speed of the warm air water pump.

[0059] Specifically, in order to further mask the working noise of the heater pump, when receiving the heating start command of the air conditioner, it is necessary to first control the blower to run for a first preset time, such as 1.5 seconds, and then control the heater pump to run. Similarly, when receiving the heating stop command of the air conditioner, it is necessary to first control the heater pump to stop running for a second preset time, such as 1 second, and then control the blower to stop running.

[0060] In this way, by controlling the opening or closing timing of the blower and the heater water pump, the working noise of the blower can be further used to mask the working noise of the heater water pump, thereby improving user comfort.

[0061] To sum up, the present invention takes the heater water pump noise perceived by the occupants of the vehicle as the control target, takes into account the heating needs of the air conditioner, controls the duty cycle of the heater water pump allowed by each gear of the blower, and at the same time, in the heating on or off stage, controls the on or off timing of the blower and the heater water pump, and makes full use of the masking effect of the working noise of the blower on the working noise of the heater water pump, which can maximize the comfort in the vehicle without increasing the hardware cost and cycle, and does not increase the cost or change the hardware.
