As shown in fig. 2, the arrow direction is the flow direction of the cooling liquid in the cooling circuit of the cabin evaporator 30, and the first control valve 20 is controlled to be opened to conduct the cooling circuit of the cabin evaporator 30 when the actual temperature of the cabin evaporator 30 is greater than the third preset temperature, and the cooling liquid in the cooling circuit of the cabin evaporator 30 circulates in the evaporator 30, the compressor 10, the condenser 60 and the first control valve 20. As shown in fig. 3, the arrow direction is the flow direction of the cooling liquid in the cooling circuit of the power battery 70, when the temperature of the power battery 70 is greater than the second preset temperature, the second control valve 50 is controlled to be opened to conduct the cooling circuit of the power battery 70, the cooling liquid in the cooling circuit of the power battery 70 circulates in the power battery 70, the heat exchanger 40, the compressor 10, the condenser 60 and the second control valve 50, and the heat of the cooling liquid is taken away by the heat exchanger 40, so as to achieve the effect of cooling the power battery 70. As shown in fig. 4, the arrow direction is the flow direction of the cooling liquid in the cooling circuit of the power battery 70 and the cooling liquid in the cooling circuit of the cabin evaporator 30, and the first control valve 20 and the second control valve 50 are controlled to be opened to simultaneously conduct the cooling circuit of the power battery 70 and the cooling circuit of the cabin evaporator 30 when the temperature of the power battery 70 is greater than the second preset temperature and the actual temperature of the cabin evaporator 30 is greater than the third preset temperature. Here, the second preset temperature and the third preset temperature may be set according to a specific design of the vehicle, and in one embodiment the second preset temperature may be 32 ℃.
According to the invention, when the vehicle has a cooling request of the cabin evaporator 30 and/or a cooling request of the power battery 70, the first control valve 20 and/or the second control valve 50 are/is selectively controlled to be opened so as to cool through the compressor 10, and finally, the temperatures of the evaporator 30 and the power battery 70 meet the requirements, and subjective feeling of passengers is met, so that the power battery 70 works in a proper temperature range, the comfort of the whole vehicle is improved, the service life of the power battery 70 is prolonged, and the safety of the whole vehicle is improved.
Further, before controlling the first control valve 20 to open, it is further required to determine whether the first control valve 20 satisfies the enabling condition, and if so, the first control valve 20 is controlled to open, wherein the enabling condition of the first control valve 20 is that the following conditions are simultaneously satisfied:
1. the air conditioner controller has no fault;
2. the fan 80 normally operates;
3. the engine is in an operating state;
4. the mass air flow through the condenser 60 is greater than 0.1;
5. the temperature of the air after the evaporator 30 is greater than-1;
6. the refrigerant pressure (high pressure side) is not excessively high.
Specifically, if it is determined through diagnosis that the air conditioner controller has requested the first control valve 20 to be enabled and the compressor 10 is operating, but does not cool, it is considered to be a malfunction; if the fault phenomenon lasts for more than 60 seconds, determining that a fault exists; forcing the switch 1 time every 1s within the first 6s after the fault is determined; determining 60s after the fault, and forcibly judging whether the fault is once again; if a cycle determines a fault 5 times, the fault is reported.
Further, before controlling the second control valve 50 to open, it is further required to determine whether the second control valve 50 meets the enabling condition, and if yes, the second control valve 50 is controlled to open, where the enabling condition of the second control valve 50 is that the following conditions are simultaneously met:
1. the power battery 70 controller has no fault;
2. the fan 80 normally operates;
3. the temperature of the power battery 70 is higher than 32 ℃;
4. the refrigerant pressure (high pressure side) is not excessively high;
5. the flow rate of the cooling liquid in the cooling circuit of the power battery 70 is not lower than 0.1;
6. the temperature of the cooling liquid in the cooling loop of the power battery 70 is not lower than 15 ℃;
7. the second control valve 50 is not forcibly closed. Because opening the second control valve 50 causes the delta of the actual temperature of the air after the evaporator 30 and the desired temperature to be greater than a certain limit, the beller valve is forced to close until the delta is again less than the limit (preventing the actual temperature of the air after the evaporator 30 from rising too much due to cooling the power cell 70.)
Further, before calculating the target rotation speed and the target power of the compressor 10, it is further required to determine whether the compressor 10 can be operated, and if so, the target rotation speed and the target power of the compressor 10 are calculated, and the compressor 10 is operated to simultaneously satisfy the following requirements:

Here, the first preset temperature may be set to 23 ℃. In addition, when the environment temperature of the vehicle is higher than 30 ℃, the highest rotation speed of the compressor is controlled under the consideration of NVH. Further, when the temperature of the coolant in the power battery cooling circuit is lower than 15 ℃, the target rotation speed of the compressor is controlled to be zero. The correspondence between the ambient temperature and the rotational speed of the compressor is shown in table 1:
TABLE 1
| Ambient temperature | -5 | 0 | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 |
| Rotational speed of compressor | 2000 | 2000 | 2000 | 2000 | 2000 | 2000 | 2000 | 2500 | 2500 | 2500 |

The method specifically comprises the following steps:
s320, when only the cooling loop of the cabin evaporator is conducted, searching from a preset storage module to obtain the internal circulation rotating speed and the external circulation rotating speed of the compressor corresponding to the target temperature, the ambient temperature and the air conditioner air quantity, calculating the PI rotating speed according to the difference value between the temperature of the cabin evaporator and the target temperature, the ambient temperature and the air conditioner air quantity through a PI algorithm, and storing the corresponding relation between the target temperature, the ambient temperature and the air conditioner air quantity and the internal circulation rotating speed and the external circulation rotating speed in the preset storage module; in one embodiment, the environment temperature can be divided into 6 environment temperature ranges, and 6 Map tables corresponding to the air conditioner air quantity, the internal circulation rotating speed and the external circulation rotating speed of the compressor in the 6 environment temperature ranges are correspondingly arranged. The 6 ambient temperature ranges may be less than 10 ℃,10 ℃ to 20 ℃,20 ℃ to 30 ℃,30 ℃ to 40 ℃,40 ℃ to 50 ℃ and greater than 50 ℃.
S321, calculating the feedforward control rotating speed of the compressor by utilizing the inner circulation rotating speed and the outer circulation rotating speed through linear interpolation;
s322, the feedforward control rotating speed and the PI rotating speed are added to calculate the target rotating speed of the compressor.
Third kind: when the power battery cooling loop and the cockpit evaporator cooling loop are both conducted, calculating the expected rotating speed of the compressor according to the temperature of the cockpit evaporator, the target temperature of the cockpit evaporator, the environment temperature of the vehicle and the air conditioner air quantity, wherein the operating parameters further comprise the target temperature of the cockpit evaporator, the environment temperature and the air conditioner air quantity. The method specifically comprises the following steps:
s330, when the power battery cooling loop and the cockpit evaporator cooling loop are both conducted, searching from a preset storage module to obtain the internal circulation rotating speed and the external circulation rotating speed of the compressor corresponding to the target temperature, the ambient temperature and the air quantity of the air conditioner, calculating the PI rotating speed through a PI algorithm according to the difference value between the temperature of the cockpit evaporator and the target temperature, the ambient temperature and the air quantity of the air conditioner, and storing the corresponding relation between the target temperature, the ambient temperature and the air quantity of the air conditioner and the internal circulation rotating speed and the external circulation rotating speed in the preset storage module; in one embodiment, the environment temperature can be divided into 6 environment temperature ranges, and 6 Map tables corresponding to the air conditioner air quantity, the internal circulation rotating speed and the external circulation rotating speed of the compressor in the 6 environment temperature ranges are correspondingly arranged. The 6 ambient temperature ranges may be less than 10 ℃,10 ℃ to 20 ℃,20 ℃ to 30 ℃,30 ℃ to 40 ℃,40 ℃ to 50 ℃ and greater than 50 ℃.
S331, calculating the feedforward control rotating speed of the compressor by utilizing the inner circulation rotating speed and the outer circulation rotating speed through linear interpolation;
s332, the feedforward control rotation speed and the PI rotation speed are added to calculate the predicted rotation speed of the compressor.
The following steps are also included:
s333, searching a low-speed value, a medium-speed value and a high-speed value of the compressor corresponding to the expected rotating speed and the ambient temperature from a preset storage module, and searching a weight coefficient corresponding to the temperature of the cooling liquid in the power battery cooling circuit, wherein the operation parameters further comprise the temperature of the cooling liquid in the power battery cooling circuit, and the preset storage module stores the corresponding relation between the expected rotating speed and the ambient temperature and the low-speed value, the medium-speed value and the high-speed value of the compressor and the corresponding relation between the temperature of the cooling liquid in the power battery cooling circuit and the weight coefficient;
s334, calculating the target rotating speed of the compressor by linear interpolation by using the low speed value, the medium speed value, the high speed value and the weight coefficient of the compressor.
Further, after the step of calculating the target rotation speed of the compressor, the following steps are included:
step one: searching and obtaining target power of the compressor corresponding to the target rotating speed of the compressor and the air-conditioning pressure of the vehicle from a preset storage module, wherein the operation parameters further comprise the air-conditioning pressure of the vehicle, and the preset storage module stores the corresponding relation between the target rotating speed of the compressor, the air-conditioning pressure and the target power of the compressor;
step two: the compressor is controlled to operate at a target speed and a target power.
In one embodiment, the target power of the compressor is added to the preset power whenever the power battery cooling circuit is turned on to obtain the final power of the compressor, and then the compressor is controlled to operate at the target rotational speed and the final power. Here, the preset power is any value ranging from 1.2KW to 1.5 KW. That is, only when the cooling circuit of the cabin evaporator is conducted, the preset power is not required to be added on the basis of the target power of the compressor, and the operation of the cooling circuit is directly controlled according to the target power of the compressor. When the power battery cooling circuit is conducted alone or together with the cabin evaporator cooling circuit, the final power is obtained by adding the preset power to the target power of the compressor, and the operation of the compressor is controlled according to the final power.
In one embodiment, the step of calculating the target rotational speed of the compressor further comprises the following steps:
searching a preset storage module to obtain the maximum limiting rotation speed of the compressor corresponding to the environment temperature of the vehicle and the speed of the vehicle, wherein the operation parameters further comprise the speed of the vehicle;
and step four, if the target rotating speed of the compressor is larger than the maximum limiting rotating speed, controlling the compressor to operate according to the maximum limiting rotating speed.
Here, since the NVH requires limiting the maximum rotation speed of the compressor, the compressor rotation speed has less influence on the NVH at a high vehicle speed, and the low vehicle speed evaluates noise caused by the high rotation speed of the compressor by the NVH, thereby setting the maximum limiting rotation speed of the compressor. The maximum limit speed of the compressor can be divided into 3 cases, the first is only the cabin evaporator cooling requirement, the second is only the power battery cooling requirement, and the third is both the cabin evaporator and the power battery cooling requirement. The maximum limit rotation speeds for the above 3 cases are also different. The invention fully considers the maximum limiting rotation speed of the compressor and can ensure the safety of the whole vehicle.
Specifically, the correspondence relationship with the ambient temperature in which the vehicle is located, the speed of the vehicle, and the maximum limit rotation speed of the compressor is as shown in table 2:
TABLE 2
| Ambient temperature | 18 | 20 | 25 | 30 | 40 | 45 |
| Maximum limit speed of evaporator cooling | 4000 | 4000 | 6000 | 7000 | 8500 | 8500 |
| Maximum limit rotation speed for cooling power battery | 5500 | 5500 | 7500 | 8500 | 8500 | 8500 |
| Evaporator&Maximum limit rotation speed for cooling power battery | 5500 | 5500 | 7500 | 8500 | 8500 | 8500 |
Further, it is also necessary to set the maximum limit rotation speed of the compressor in the following cases:
(1) Limiting the maximum limiting rotation speed of the compressor when the compressor is operated for the first time, wherein the initial operation time of the compressor is less than 200s, and the maximum limiting rotation speed is 800rpm;
(2) The speed of the motor is less than 10km/h, broadband noise is reduced after the air conditioner is started, the maximum limit rotating speed of the compressor is set according to the time for starting the air conditioner, and the limit is released after the starting time exceeds 50 s;
(3) Since the power battery is in a low-power state, the maximum rotation speed of the compressor is limited after the required power of the compressor is reduced. After the electric quantity of the power battery is reduced, the allowable power of the compressor is reduced, so that the difference between the required rotating speed and the actual rotating speed is overlarge, and the function is to limit the required rotating speed limit value by using the actual rotating speed and limit the required rotating speed according to the distributed power.
(4) The maximum limit rotation speed of the compressor is defined by the local temperature or pressure of the vehicle system, specifically:
A. evaporator temperature limit: the temperature of the evaporator is lower than 2 ℃, and the maximum limit rotation speed of the compressor is 0;
B. engine water temperature limit: the transient water temperature exceeds 125 ℃, and the maximum limit rotation speed of the compressor is 0;
C. engine oil temperature limit: the steady-state oil temperature of the engine exceeds 130 ℃, and the maximum limit rotating speed of the compressor is 0;
D. refrigerant pressure limitation: and according to the fact that the input pressure of the whole vehicle exceeds 30Bar, the maximum limit rotating speed of the compressor is 0.
Further, it is also necessary to set a minimum limit rotation speed of the compressor, which is set to prevent the risk of overtemperature of the entire cooling system, so that the minimum limit rotation speed is limited after the maximum limit rotation speed. Generally, there are 3 cases, the first: only the cooling requirement of the cabin evaporator, and obtaining the minimum limiting rotation speed of the compressor according to the table look-up of the ambient temperature; second kind: only the cooling requirement of the power battery, and obtaining the minimum limiting rotating speed of the compressor according to the table look-up of the ambient temperature; third kind: the cockpit evaporator and the power battery have cooling requirements at the same time, and the minimum limiting rotation speed of the compressor is obtained according to an ambient temperature lookup table. Each of these 3 cases has a map table.
