Because the parameters of each air conditioner air outlet are different evaluation parameters, such as the temperature in the vehicle, the sunlight intensity and the like, and the unified item analysis cannot be carried out, the energy demand gear value is defined, and the parameters of each air conditioner air outlet are quantized into the unified energy demand value through the weight coefficient so as to be analyzed conveniently. The state corresponding to the minimum energy demand gear value in the energy demand value range is that the air conditioner is extremely cold, namely the opening degree of the mixing air door is a fully cold end, the heat source is closed, and the cold source is opened to the lowest temperature. The state corresponding to the maximum energy demand gear value in the energy demand value range is that the air conditioner is extremely hot, namely the opening degree of the air mixing door is a full hot end, the cold source is closed, and the heat source is opened to the maximum temperature.

The cold source and the heat source are power sources for providing cold air and heat for the air conditioner, respectively, for example, the target temperature of the heat source is a target water temperature, and the target temperature of the cold source is a target temperature of the evaporator.
According to the invention, the air conditioner air outlet parameters of different evaluation dimensions are quantized by setting the gear value of the energy demand, and different working conditions of the air conditioner can be analyzed by using a unified standard, so that the parameters of the air conditioner can be accurately controlled in the following process.

According to the in-vehicle temperature Tinc and the corresponding weight coefficient K1Obtaining a required value (Tset-Tinc) of the temperature in the vehicle1According to the ambient temperature Tout and the corresponding weight coefficient K2Obtaining the ambient temperature demand value Tout K2Based on the set temperature Tset and the corresponding weight coefficient K3Obtaining a set temperature demand value (Tset-T) K3T is a set comfortable temperature of human body, generally 24 degrees, according to the sunlight intensity SUN and the corresponding weight coefficient K4Obtaining the sunlight intensity requirement value SUN K4According to the vehicle speed Veh and the corresponding weight coefficient K5Obtaining the vehicle speed demand value Veh K5。
An energy demand value base is obtained from the energy demand value range, which is the middle value of the energy demand value range, V, which is set to 124, for example, when the energy demand value range is 0-248.

According to the invention, the energy demand gear value is set, and then the air conditioner air outlet parameters with different evaluation dimensions are converted into the energy demand gear value through a formula for quantification, so that different working conditions of the air conditioner can be analyzed by using a uniform standard.
Optionally, as shown in fig. 3, in another embodiment of the present invention, after the step of "S200 obtaining an energy demand stage value according to the air-conditioner air outlet parameter, the weighting factor and the energy demand value range", the method includes the following steps:

And finally, acquiring and adjusting corresponding target air conditioner execution parameters according to the first mapping relation and the energy demand gear value.
Optionally, in another embodiment of the present invention, the step of "S300 adjusting the opening of the mixing damper, the target temperature of the heat source, and the target temperature of the heat sink according to the energy demand gear value" includes the steps of:
s310, when the environment temperature is higher than or equal to a first preset temperature, adjusting the opening of the mixing air door to be in a cold air mode, and adjusting the cold source target temperature according to the energy demand gear value;
and S320, when the environment temperature is lower than a first preset temperature, adjusting a mixing air door to be in an air mixing mode, and adjusting the opening degree of the mixing air door, the target temperature of the heat source and the target temperature of the cold source according to the gear value of the energy demand.
Specifically, in this embodiment, when the ambient temperature is greater than or equal to the first preset temperature, the current environment is defined as the summer mode, and no cold air needs to be provided, so that the opening of the mixing damper is adjusted to the cold air mode, and the cold source target temperature is adjusted according to the gear value of the energy demand.
When the environment temperature is lower than the first preset temperature, the current environment is defined to be in a non-summer mode, the driver's requirement can be warm air or cold air, and defrosting can be needed, so that the air mixing door is adjusted to be in an air mixing mode, and the opening degree of the air mixing door, the target temperature of the heat source and the target temperature of the cold source are adjusted according to the gear value of the energy requirement.
And for the non-summer mode, when the ambient temperature is greater than or equal to the second preset temperature and less than the first preset temperature, defining that the current mode is in a spring and autumn mode. And if the air conditioner is detected to be in the automatic adjusting mode, namely the user does not set a specific mode independently, adjusting the air mixing door to be in the air mixing mode, and adjusting the opening of the air mixing door, the target temperature of the heat source and the target temperature of the cold source according to the gear value required by energy.
And when the ambient temperature is lower than a second preset temperature, defining that the winter mode is currently in. The driver demand is generally hot air, but if defrosting is required, an air conditioner is required to provide cold air. Therefore, when the opening of the defrosting mode of the air conditioner is detected, the air mixing door is adjusted to be in the air mixing mode, and the opening degree of the air mixing door, the target temperature of the heat source and the target temperature of the cold source are adjusted according to the gear value of the energy demand. And if the defrosting mode of the air conditioner is not started, adjusting the mixing air door to be in a hot air mode, and adjusting the target temperature of the heat source and the target temperature of the cold source according to the gear value required by energy.
Optionally, in another embodiment of the present invention, the step of "S321, when the ambient temperature is greater than or equal to a second preset temperature and less than a first preset temperature and an air conditioner is detected to be in an automatic adjustment mode, adjusting a mixing damper to be in an air mixing mode, and adjusting the opening of the mixing damper, the target temperature of the heat source, and the target temperature of the cold source according to the gear value of the energy demand" includes the following steps:
s322, when the environment temperature is greater than or equal to a second preset temperature and less than a first preset temperature and the air conditioner is detected to be in an automatic adjusting mode, adjusting the air mixing door to be in an air mixing mode;
s323, when the gear value of the energy demand is larger than or equal to a preset gear value, adjusting the opening of the mixing air door to a full hot end preset range;

and S325, adjusting the target temperature of the heat source and the target temperature of the cold source according to the gear value of the energy demand.
Specifically, in this embodiment, when the ambient temperature is greater than or equal to the second preset temperature and less than the first preset temperature, it is defined that the current mode is in the spring and autumn mode. And if the air conditioner is detected to be in the automatic adjusting mode, namely the user does not set a specific mode independently, adjusting the mixing air door to be in the air mixing mode. Under different mixed air door openness, the energy loss of the cold and hot mixed air is different, in order to reduce the energy loss of the cold and hot mixed air as much as possible, the current deviation is more to refrigeration or heating according to the energy demand gear value identification, when the energy demand gear value is more than or equal to the preset gear value, the deviation to heating is analyzed, and therefore the mixed air door openness is adjusted to the full-hot end preset range. When the gear value of the energy demand is smaller than the preset gear value, the deviation of the energy demand gear value to heating is analyzed, and therefore the opening degree of the mixing air door is adjusted to be in the full cold end preset range. For example, in spring and autumn (ambient temperature 8-22 ℃), in the automatic mode, when the valvg value is greater than or equal to 60, the blend door is at approximately the full hot end (the blend door is at 0% -10%); when the Valavg value is less than 60, the blend door is in full cold side operation (blend door is at 90% -100%). And simultaneously, adjusting the target temperature of the heat source and the target temperature of the cold source according to the gear value of the energy demand.
According to the invention, the opening of the mixing air door is controlled through environmental temperature constraint, and the target temperature of the heat source and the target temperature of the cold source are controlled simultaneously, so that the energy loss of cold and hot mixed air is reduced.
