When vehicle interior temperature is at 7 DEG C or less, compressor guarantees that pipeline is not damaged by frost with the rotary speed working of 1000rmp/min.
After the speed and evaporation utensil temperature for reaching setting, the order of 10s delayed execution is set before Program transformation, to avoid
When 20km/h hovers back and forth, the frequent change dramatically of compressor rotary speed causes to damage speed to compressor itself.
The present invention by adopting the above technical scheme, by changing VCU to the control strategy of air-conditioning system, is taking into account air conditioner refrigerating
While effect, significantly reduce in idling and vibration and noise due to caused by compressor body during running at a low speed,
The comfortable riding space of peace and quiet is provided for driver and passenger, improves the comfort and driving of driving；Air-conditioning duct is protected, is kept away
Exempt from the damage because caused by compressor crosses refrigeration；It efficiently reduces because redesigning exploitation compressor and re-starting arrangement
Caused by cost；Above-mentioned technical proposal can be promoted and applied when solving other new energy project similar problems.
Detailed description of the invention
Label in content and figure shown in attached drawing is briefly described as follows:
Fig. 1 is control strategy schematic diagram of the invention.
In the figure, it is marked as
1, cooling signals input, 2, speed, 3, air-conditioning evaporating dish surface temperature, 4, compressor rotary speed, 5, control signal it is defeated
Out.
Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Illustrate, to help those skilled in the art to have more complete, accurate and deep reason to inventive concept of the invention, technical solution
Solution.
The present invention relates to new energy vehicle air-conditioning refrigeration system temperature to adjust field, is embodied in new-energy automotive air-conditioning
During cooling system, takes into account air conditioner refrigerating and reduce the VCU of vibration of compressor and noise control plan under idling and speed operation
Slightly.Control strategy of the invention as shown in Figure 1 is a kind of new-energy automotive air-conditioning refrigeration system VCU control method.In order to overcome
The defect of the prior art realizes the goal of the invention for improving the comfort driven, the technical scheme adopted by the invention is as follows:
As shown in Figure 1, new-energy automotive air-conditioning refrigeration system VCU control method of the invention is: in vehicle travel process
In, freezed using the speed parameter and vehicle interior temperature parameter co- controlling air-conditioning system of vehicle.
In Fig. 1, cooling signals input 1 indicates that air-conditioning system is inputted to cooling signals；Speed 2 indicates that VCU determines vehicle
Travel speed；Air-conditioning evaporating dish surface temperature 3 is the surface temperature that VCU determines A/C evaporator ware, and compressor rotary speed 4 is specific
Under the conditions of speed, temperature, compressor rotary speed；And control signal output 5.
The present invention is VCU control strategy in the one of new energy vehicle interior temperature control system, the compressor of air conditioner control of Fig. 1
System strategy is the design framework thinking of VCU control strategy of the invention.The Integral Thought of the control strategy is: changing traditional vehicle
Using vehicle interior temperature as single signal, replace with the speed and vehicle interior temperature co- controlling air-conditioning system system in vehicle travel process
It is cold.
The VCU control strategy change tradition it is single using temperature as air-conditioning system input signal in a manner of, and then be replaced by
By speed as led signal, crew module's temperature for auxiliary signal in the way of, take into account vehicle interior temperature adjust while, be effectively reduced
The vibration of car caused by compressor of air conditioner and noise improve interior comfort；New energy vehicle car NVH performance is improved,
The comfortable interior space of peace and quiet is provided for customer, increases the satisfaction of passenger inside the vehicle.
VCU detects air-conditioning evaporating dish surface temperature 3, and then controls compressor rotary speed 4, reaches the mesh of damping noise reduction
's.
When passenger inside the vehicle opens crew module's refrigeration knob, which is transferred to VCU；VCU, which controls program, first believes speed 2
Number judged, judge that there are two types of operating conditions to speed 2: the first operating condition is speed >=20km/h；Second of operating condition is speed <
20km/h is until 0；Under two kinds of operating conditions, VCU detects air-conditioning evaporating dish surface temperature 3, and then controls compressor and turn
Speed 4, achievees the purpose that damping noise reduction.
Specifically:
1, under speed >=20km/h operating condition:
When temperature is greater than 13 DEG C, compressor guarantees the refrigeration effect of air-conditioning with the rotary speed working of 4500rmp/min；
When vehicle interior temperature is between 7 DEG C to 13 DEG C, compressor guarantees air-conditioning with the rotary speed working of 3000rmp/min
Refrigeration effect；
When vehicle interior temperature is at 7 DEG C or less, compressor guarantees that pipeline is not damaged by frost with the rotary speed working of 1000rmp/min.
2, in speed < 20km/h, until under the operating condition of speed=0:
When vehicle interior temperature is at 7 DEG C or more, compressor sacrifices part air conditioner refrigerating with the rotary speed working of 3000rmp/min
Performance (13 DEG C or more freeze) reduces interior vibration and noise, guarantees the comfort that crew module takes；
When vehicle interior temperature is at 7 DEG C or less, compressor guarantees that pipeline is not damaged by frost with the rotary speed working of 1000rmp/min.
After the speed 2 and air-conditioning evaporating dish surface temperature 3 for reaching setting, 10s delay is set before controlling Program transformation
Order is executed, to avoid speed 2 when 20km/h hovers back and forth, the frequent change dramatically of compressor rotary speed 4 is to compressor itself
It causes to damage.
Taking the beneficial effect of above-mentioned technical proposal is:
1, air-conditioning system cooling condition is significantly reduced to get off internal vibration and noise；
2, interior comfort and driving are improved, provides the comfortable riding space of peace and quiet for driver and passenger；Protection
Air-conditioning duct damage because caused by compressor crosses refrigeration；
3, the cost for redesigning exploitation compressor and re-starting arrangement work is effectively reduced；
4, this can be promoted and applied during solving other new energy project similar problems.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing
It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
