Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
The method for controlling the rotating speed of the automobile air conditioner compressor, as shown in figure 1, comprises the following steps:
step S101: acquiring the voltage of the blower under the current gear of the blower, and determining the noise of the blower generated when the blower is in the current gear under the vehicle according to the voltage of the blower;
step S102: calculating the maximum compressor noise in the vehicle, which is allowed to be generated by the compressor, according to the blower noise, and determining the maximum allowed rotating speed of the compressor under the current working condition according to the maximum compressor noise;
step S103: controlling the rotation speed of the compressor not to exceed the maximum allowable rotation speed of the compressor.
Specifically, the automobile air blower is used for controlling the air outlet volume of the air conditioner, in the automobile, the gears of the air blower are provided with seven gears or more, and the air outlet intensity of the air conditioner can be adjusted by adjusting the gears of the air blower by a driver and passengers. Blower shifting is actually the adjustment of the blower voltage, which during operation generates blower noise, and which increases as the blower voltage increases. Therefore, the rotating speed of the compressor can be controlled to be equivalent to the noise of the blower, and the noise of the compressor is not easy to be sensed by drivers and passengers under the condition of the noise of the blower being covered. In the present invention, the blower noise and the compressor noise are both the blower noise and the compressor noise sensed in the vehicle.
The method comprises the steps of firstly obtaining the blower voltage of a blower under the current gear according to different blower noises generated by the blower in different gears, then determining the blower noise under the current gear according to the blower voltage, then calculating the maximum compressor noise generated by an allowable compressor according to the blower noise, wherein the maximum compressor noise can not be easily sensed under the current blower noise, obtaining the calculation relation between the maximum compressor noise and the allowable compressor noise through a simulation test, and finally determining the maximum allowable rotating speed of the compressor under the working conditions of the current blower gear and the current air conditioning system according to the relation between the compressor noise and the rotating speed of the compressor.
The rotating speed control method of the automobile air conditioner compressor in the embodiment is combined with the gear of the current air blower to regulate and control the rotating speed of the compressor, so that the noise of the compressor is always kept equivalent to the noise level of the air blower, and drivers and passengers are not easy to perceive the noise of the compressor.
As an example, according to the above-mentioned operation steps, a direct relationship between the compressor rotation speed and the blower gear is calculated, and the compressor rotation speed is rapidly adjusted.
In one embodiment, the determining the blower noise generated when the blower is in the current gear according to the blower voltage includes:
determining the blower noise Nb generated when the blower is in the current gear as C ㏑ u + D, wherein u is the blower voltage and C, D is a coefficient.
Through above-mentioned technical scheme, acquire the direct relation between air-blower noise data and the gear.
Specifically, a calculation method for obtaining the noise of the blower is obtained by fitting a blower noise curve according to corresponding blower noise data under the blower voltages of different gears.
As an example, fig. 2 shows a blower noise curve obtained by fitting noise data of the blower corresponding to different gear voltages under the actual air-conditioning operation condition of the vehicle in a certain type of vehicle, and through data analysis, the relationship between the blower noise and the blower voltage is Nb ═ C ㏑ u + D, wherein the coefficient C, D is related to the impeller order and the structure type of the blower.
In one embodiment, the calculating a maximum compressor noise in the vehicle that is allowed to be generated by the compressor according to the blower noise and determining a maximum allowable rotation speed of the compressor under the current operating condition according to the maximum compressor noise includes:
determining the maximum noise difference value allowed by an air conditioning system when the compressor is operated and closed according to a noise target value (referring to an NVH performance target) of the air conditioning system of the real vehicle, wherein the sum of the fan noise and the maximum noise difference value is used as the maximum compressor noise;
and determining the maximum allowable rotating speed r of the current compressor as (Nc-B)/A, wherein Nc is the maximum compressor noise and A, B is a coefficient.
Through the technical scheme, the direct relation between the noise of the compressor and the rotating speed of the compressor is obtained, and therefore the maximum allowable rotating speed of the compressor is calculated according to the maximum noise of the compressor.
As an example, referring to an air conditioner NVH performance target, an actual vehicle air conditioning system noise target value is determined that keeps compressor noise less perceptible, Nc-Nb ≦ X, where Nc is the compressor noise, Nb is the blower noise, and X is the maximum noise difference. That is, when the difference between the compressor noise and the blower noise is not greater than XdB, it is difficult for the customer to perceive the compressor noise. With regard to the value of X, adaptation can be made for different vehicle models.
Regarding the direct relationship between the compressor noise and the compressor rotation speed, fig. 3 shows that for a certain type of automobile, a rotation speed noise curve of the compressor is obtained by fitting noise data corresponding to different rotation speeds of the compressor under the actual air-conditioning operation condition of the cold room, and through data analysis, the compressor noise and the compressor rotation speed are in a linear relationship, specifically, Nc is equal to Ar + B, wherein a coefficient A, B is related to the displacement machine and the structure type of the compressor, so that the maximum rotation speed r of the compressor is equal to (Nc-B)/a.
In one embodiment, the blower noise is combined with the blower voltage by: nb is C ㏑ u + D, and the relation between the compressor noise and the compressor speed is as follows: nc is Ar + B, and the relationship between compressor noise and blower noise: Nc-Nb is less than or equal to X; the relationship between the compressor speed and the blower voltage can be obtained:
r≤(C㏑u+D-B+X)/A
where u is the blower voltage and A, B, C, D is a coefficient.
In this embodiment, according to the above relational expression, the maximum allowable rotation speed of the compressor under the current working condition can be directly calculated according to the current blower gear, so that the steps of data processing are reduced, and the processing method is optimized.
In one embodiment, the method for controlling the rotating speed of the compressor of the automobile air conditioner further comprises the following steps:
determining the upper limit rotating speed of the compressor allowed under the current air conditioner setting condition;
and when the maximum allowable rotating speed of the compressor is greater than the upper limit rotating speed of the compressor, controlling the rotating speed of the compressor not to exceed the upper limit rotating speed of the compressor.
In the foregoing embodiments, the maximum allowable rotation speed of the compressor increases with the increase of the gear of the blower, however, during the operation of the compressor, the rotation speed of the compressor also depends on the air conditioning performance of the vehicle, and the like, and accordingly, the upper limit rotation speed of the compressor needs to be set in combination with the air conditioning performance and the like to ensure the normal operation of the compressor.
In the embodiment, when the maximum allowable rotating speed of the compressor calculated according to the gear position of the blower is greater than the upper limit rotating speed of the compressor, the compressor is controlled to rotate at the upper limit rotating speed of the compressor, and the rotating speed of the compressor is limited not to exceed the upper limit rotating speed of the compressor.
As an example, fig. 4 shows a schematic diagram of the maximum allowable compressor rotation speed for different blower speeds for a certain vehicle model. The blower is provided with seven gears, and in the gears 1-4, the maximum allowable rotating speed of the compressor is increased along with the increase of the gears, and in the gears 4-7, the maximum allowable rotating speed of the compressor is the upper limit rotating speed Nc max of the compressor.

acquiring the thermal load of the vehicle and the set temperature of the air conditioner, and calculating the mass flow output by the compressor;
and determining the upper limit rotating speed of the compressor according to the performance of the compressor and the mass flow output by the compressor.

The cold energy generated by the mass flow output by the compressor is enough to offset the current vehicle heat load, when the temperature in the vehicle is reduced to the set temperature of the air conditioner, the mass flow output by the compressor is the upper limit value of the mass flow, and the corresponding compressor rotating speed is the upper limit rotating speed of the compressor allowed under the set condition of the current air conditioner. The rotating speed of the compressor is controlled not to be larger than the upper limit rotating speed of the compressor so as to prevent the temperature in the vehicle from not conforming to the set temperature of the air conditioner.
