[0054] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application.

[0055] To make the purpose, technical solution and advantages of this application clearer, the embodiments of this application will be further described in detail below in conjunction with the drawings.

[0056] In a first aspect, an embodiment of this application provides a method for improving the perceived comfort of a cockpit.

[0057] In one embodiment, referring to Figure 1 , Figure 1 is a schematic flowchart of an embodiment of the method for improving the perceived comfort of the cockpit of this application. As Figure 1 shown, the method for improving the perceived comfort of the cockpit includes:

[0058] Step S10: Calculate the target hot air intake volume for the current cycle and the target cold air intake volume for the current cycle according to the target cockpit temperature, the actual cockpit temperature, the target hot air intake volume in the previous cycle, and the preset total periodic intake volume of hot and cold air.

[0059] In this embodiment, the target cockpit temperature can be input from a user terminal, the actual cockpit temperature is measured by a temperature sensor installed in the cockpit. For the hot and cold air intake volumes, a periodic cyclic adjustment control method is adopted. For example, 1 second or 2 seconds, etc. is used as a control adjustment cycle. The target hot air intake volume in the previous cycle can start from an initial value of 0, and the preset total periodic intake volume of hot and cold air is the sum of the target hot air intake volume and the target cold air intake volume in one cycle.

[0060] Step S20: Calculate the hot air intake volume difference value and the cold air intake volume difference value according to the target hot air intake volume for the current cycle, the target cold air intake volume for the current cycle, the actual hot air intake volume in the previous cycle, and the actual cold air intake volume in the previous cycle.

[0061] In this embodiment, according to the target hot air intake volume for the current cycle, the target cold air intake volume for the current cycle, the actual hot air intake volume in the previous cycle, and the actual cold air intake volume in the previous cycle, the hot air intake volume difference value and the cold air intake volume difference value can be calculated through the formula. The formula is: where ΔQ hot is the hot air intake volume difference value, ΔQclod is the difference value of cold air intake volume, Q hot is the target hot air intake volume for the current cycle, Q1(K - 1) hot is the executed hot air intake volume for the previous cycle, Q clod is the target cold air intake volume for the current cycle, Q1(K - 1) clod is the executed cold air intake volume for the previous cycle.

[0062] Step S30: Determine the number of cycles required for the synchronous execution of hot and cold air based on the difference value of hot air intake volume, the difference value of cold air intake volume, the maximum mechanical limit of the periodic intake volume of the hot air pipeline, and the maximum mechanical limit of the periodic intake volume of the cold air pipeline.

[0063] In this embodiment, the difference value of hot air intake volume and the difference value of cold air intake volume are usually different. The maximum mechanical limit of the periodic intake volume of the hot air pipeline and the maximum mechanical limit of the periodic intake volume of the cold air pipeline respectively represent the maximum intake volume determined by the mechanical design of the hot air pipeline and the cold air pipeline in one cycle, and the two may also be different. Therefore, the hot air pipeline may require 3 cycles to complete the intake target volume, while the cold air pipeline may require 6 cycles to complete the intake target volume. In order to enable the hot air pipeline and the cold air pipeline to synchronously complete their respective intake target volumes, determine the number of cycles required for the synchronous execution of hot and cold air, and by adjusting the speed of hot and cold air intake, enable the two to synchronously complete their respective intake target volumes.

[0064] Step S40: Simultaneously adjust the opening degrees of the hot air intake pipeline and the cold air intake pipeline for the current cycle according to the number of cycles required for the synchronous execution of hot and cold air, the difference value of hot air intake volume, and the difference value of cold air intake volume.

[0065] In this embodiment, the speed of hot and cold air intake is adjusted by adjusting the opening degrees of the hot air intake pipeline and the cold air intake pipeline. The opening degrees of the hot air intake pipeline and the cold air intake pipeline are adjusted simultaneously to enable the two to synchronously complete their respective intake target volumes. Since the intake volumes of the hot and cold air pipelines are adjusted simultaneously, it can make the mixing of hot and cold air more uniform, and through gradual adjustment in multiple cycles, avoid too rapid increase or decrease in temperature, and can improve the comfort of the driver and passengers' perception of hot and cold in the cockpit.

[0066] In this embodiment, the target temperature of the cockpit can be obtained from the input of the user terminal. The actual temperature of the cockpit is measured by a temperature sensor installed in the cockpit. For the hot and cold air intake amounts, a periodic cycle adjustment control method is adopted. For example, one second or two seconds, etc., is used as a control adjustment cycle. The difference value of the hot air intake amount and the difference value of the cold air intake amount can be calculated through a formula based on the target hot air intake amount of the current cycle, the target cold air intake amount of the current cycle, the executed hot air intake amount of the previous cycle, and the executed cold air intake amount of the previous cycle. In order to enable the hot air pipeline and the cold air pipeline to complete their respective intake target amounts synchronously, the number of cycles required for the hot and cold air to complete the execution synchronously is determined. By adjusting the speed of the hot and cold air intakes, the two can complete their respective intake target amounts synchronously. The speed of the hot and cold air intakes is adjusted by adjusting the opening degrees of the hot air intake pipeline and the cold air intake pipeline. The opening degrees of the hot air intake pipeline and the cold air intake pipeline are adjusted simultaneously, so that the two can complete their respective intake target amounts synchronously. Since the intake amounts of the hot and cold air pipelines are adjusted simultaneously, the hot and cold air can be mixed more evenly. And through gradual adjustment in multiple cycles, the temperature increase or decrease can be avoided too quickly, which can improve the comfort of the driver and passengers' perception of the hot and cold in the cockpit.

[0067] Further, in one embodiment, referring to Figure 2 , Figure 2 is the detailed process schematic diagram of step S10 in this application Figure 1 . As shown in Figure 2 , step S10 includes:

[0068] Step S101, if the target temperature of the cockpit is greater than the actual temperature of the cockpit, then use the target hot air intake amount of the previous cycle plus the preset cycle interval control amount to calculate the target hot air intake amount of the current cycle;

[0069] Step S102, if the target temperature of the cockpit is less than the actual temperature of the cockpit, then use the target hot air intake amount of the previous cycle minus the preset cycle interval control amount to calculate the target hot air intake amount of the current cycle;

[0070] Step S103, if the target temperature of the cockpit is equal to the actual temperature of the cockpit, then use the target hot air intake amount of the previous cycle as the target hot air intake amount of the current cycle;

[0071] Step S104, use the preset total hot and cold air cycle intake amount minus the target hot air intake amount of the current cycle to calculate the target cold air intake amount of the current cycle.

[0072] In this embodiment, based on the target temperature of the cockpit, the actual temperature of the cockpit, the target amount of hot air intake in the previous cycle, and the preset total intake of hot and cold air in a cycle, the target amount of hot air intake in the current cycle and the target amount of cold air intake in the current cycle can be calculated through a formula. The formula is as follows: Where, Q hot is the target amount of hot air intake in the current cycle, Qlast hot is the target amount of hot air intake in the previous cycle, which can start from the initial value of 0, Q clod is the target amount of cold air intake in the current cycle, ΔQ is the preset interval control amount between cycles, which can be set according to specific requirements, Q is the preset total intake of hot and cold air in a cycle, which is the sum of the target amount of hot air intake and the target amount of cold air intake in a cycle, and can be calibrated according to the size of the cockpit space, T targrt is the target temperature of the cockpit, T act is the actual temperature of the cockpit.

[0073] Furthermore, in one embodiment, referring to Figure 3 , Figure 3 is the detailed process schematic diagram of step S30 in this application. As shown in Figure 1 , step S30 includes: Figure 3 shown, step S30 includes:

[0074] Step S301, calculate the minimum number of cycles required to execute the hot air difference value and the minimum number of cycles required to execute the cold air difference value according to the hot air differential intake amount difference value, the cold air intake amount difference value, the maximum mechanical limit of the hot air pipeline cycle intake amount, and the maximum mechanical limit of the cold air pipeline cycle intake amount;

[0077] Step S304, take the larger value of the theoretical number of cycles required to execute the hot air difference value and the theoretical number of cycles required to execute the cold air difference value as the number of cycles required to complete the synchronization of hot and cold air.

[0078] In this embodiment, according to the difference value of the hot air intake volume, the difference value of the cold air intake volume, the maximum mechanical limit of the periodic intake volume of the hot air pipeline, and the maximum mechanical limit of the periodic intake volume of the cold air pipeline, the minimum number of required cycles for executing the hot air difference value and the minimum number of required cycles for executing the cold air difference value can be calculated through a formula. The formula is: Wherein, N hot is the minimum number of required cycles for executing the hot air difference value, N clod is the minimum number of required cycles for executing the cold air difference value, ΔQ hot is the difference value of the hot air intake volume, ΔQ hotlimit is the maximum mechanical limit of the periodic intake volume of the hot air pipeline, ΔQ clod is the difference value of the cold air intake volume, ΔQ clodlimit is the maximum mechanical limit of the periodic intake volume of the cold air pipeline. According to the minimum number of required cycles for executing the hot air difference value, the minimum number of required cycles for executing the cold air difference value, the hot air steady control coefficient, and the cold air steady control coefficient, the theoretical number of required cycles for executing the hot air difference value and the theoretical number of required cycles for executing the cold air difference value can be calculated through a formula. The formula is: Wherein, N1 hot is the theoretical number of required cycles for executing the hot air difference value, N1 clod is the theoretical number of required cycles for executing the cold air difference value, N hot is the minimum number of required cycles for executing the hot air difference value, N clod is the minimum number of required cycles for executing the cold air difference value, ρ hot is the hot air steady control coefficient, ρ clod is the cold air steady control coefficient. Finally, the larger value between the theoretical number of required cycles for executing the hot air difference value and the theoretical number of required cycles for executing the cold air difference value is used as the number of required cycles for synchronously completing the execution of the hot and cold air.

[0079] Furthermore, in one embodiment, referring to Figure 4 , Figure 4 is the detailed flowchart of step S40 in this application. As shown in Figure 1 , Figure 4 shown, step S40 includes:

[0080] Step S401, dividing the difference value of the hot air intake volume and the difference value of the cold air intake volume by the number of required cycles for synchronously completing the execution of the hot and cold air respectively to calculate the hot air execution change amount and the cold air execution change amount;

[0081] Step S402: Calculate the current cycle execution amount of hot air intake and the current cycle execution amount of cold air intake based on the change amount of hot air execution, the change amount of cold air execution, the execution amount of hot air intake in the previous cycle, and the execution amount of cold air intake in the previous cycle.

[0082] Step S403: Calculate the opening degree of the hot air intake pipeline and the opening degree of the cold air intake pipeline based on the current cycle execution amount of hot air intake, the current cycle execution amount of cold air intake, the hot air pipeline opening degree conversion coefficient, and the cold air pipeline opening degree conversion coefficient.

[0083] Step S404: Adjust the opening degrees of the hot air intake pipeline and the cold air intake pipeline in the current cycle simultaneously according to the opening degrees of the hot air intake pipeline and the cold air intake pipeline.

[0084] In this embodiment, based on the hot air intake volume difference value, the cold air intake volume difference value, and the number of cycles required for the synchronous completion of hot and cold air execution, the change amount of hot air execution and the change amount of cold air execution can be calculated through the formula. The formula is: where, ΔQ1 hot is the change amount of hot air execution, ΔQ1 clod is the change amount of cold air execution, ΔQ hot is the hot air intake volume difference value, ΔQ clod is the cold air intake volume difference value, N is the number of cycles required for the synchronous completion of hot and cold air execution. Based on the change amount of hot air execution, the change amount of cold air execution, the execution amount of hot air intake in the previous cycle, and the execution amount of cold air intake in the previous cycle, the current cycle execution amount of hot air intake and the current cycle execution amount of cold air intake can be calculated through the formula. The formula is: where, Q1(K) hot is the current cycle execution amount of hot air intake, Q1(K) clod is the current cycle execution amount of cold air intake, Q1(K - 1) hot is the execution amount of hot air intake in the previous cycle, Q1(K - 1) clod is the execution amount of cold air intake in the previous cycle, ΔQ1 hot is the change amount of hot air execution, ΔQ1 clod is the change amount of cold air execution. Based on the current cycle execution amount of hot air intake, the current cycle execution amount of cold air intake, the hot air pipeline opening degree conversion coefficient, and the cold air pipeline opening degree conversion coefficient, the opening degree of the hot air intake pipeline and the opening degree of the cold air intake pipeline can be calculated through the formula. The formula is: where, γ(K) hot is the opening degree of the hot air intake pipeline, γ(K) clod is the opening degree of the cold air intake pipeline, β hot is the hot air pipeline opening degree conversion coefficient, βcold is the opening conversion coefficient of the cold air pipeline, Q1(K) hot is the execution amount of the current cycle of the hot air intake, Q1(K) clod is the execution amount of the current cycle of the cold air intake.

[0085] Further, in one embodiment, step S302 includes:

[0086] According to the hot air differential intake volume difference value, the cold air intake volume difference value, and the preset total hot and cold air cycle intake volume, the hot air stable control coefficient and the cold air stable control coefficient are calculated through the formula. The formula is:

[0087]

[0088] where ρ hot is the hot air stable control coefficient, ρ clod is the cold air stable control coefficient, ΔQ hot is the hot air differential intake volume difference value, ΔQ clod is the cold air differential intake volume difference value, and Q is the preset total hot and cold air cycle intake volume.

[0089] In this embodiment, according to the foregoing formula: It can be seen that the hot air differential intake volume difference value is the difference between the hot air intake target amount of the current cycle and the hot air intake execution amount of the previous cycle, and the cold air differential intake volume difference value is the difference between the cold air intake target amount of the current cycle and the cold air intake execution amount of the previous cycle. And to complete their respective intake target amounts, the hot and cold intake pipelines are restricted by the preset total hot and cold air cycle intake volume. In order to smoothly achieve the intake target amounts of the hot and cold intake pipelines respectively, it is necessary to calculate the appropriate hot air stable control coefficient and cold air stable control coefficient according to the hot air differential intake volume difference value, the cold air intake volume difference value, and the preset total hot and cold air cycle intake volume.

[0090] It should be noted that according to the hot air execution change amount, the cold air execution change amount, the hot air differential intake volume difference value, and the cold air intake volume difference value, the time required for the hot air and the cold air to reach the intake target amount can be calculated through the formula. The formula is: where time hot is the time required for the hot air to reach the intake target amount, time clod is the time required for the cold air to reach the intake target amount, ΔQ hot is the hot air intake volume difference value, ΔQ clod is the cold air intake volume difference value, ΔQ1 hot is the hot air execution change amount, ΔQ1 clod is the cold air execution change amount. Substitute the foregoing formula into It can be obtained that: Through derivation, it can be known that: That is, time hot = time clod , that is, the time required for the hot air to reach the intake target amount is the same as the time required for the cold air to reach the intake target amount, that is, the hot and cold intake pipelines can complete their respective intake target amounts synchronously, and the change processes of the hot and cold air intake amounts are uniform and synchronous, which can avoid the problems of uneven mixing and asynchrony of the hot and cold air, and improve the comfort of the driver and passengers' perception of the hot and cold in the cockpit.

[0091] It should also be noted that according to the formula it can be known that: This is because after substituting the previous formula into the latter formula, the numerators on both the left and right sides of the formula are the same, while the denominator N on the left side ≥ the denominator N on the right side hot , and N ≥ N clod . Further substituting the formula into it can be obtained that: Through derivation, it can be known that: That is, the absolute value of the change amount executed by the hot air and the absolute value of the change amount executed by the cold air are respectively less than or equal to the maximum mechanical limit of the periodic intake amount of the hot air pipeline and the difference value of the cold air intake amount, so as to avoid excessive intake amounts of the hot and cold intake pipelines and avoid damage to the hot and cold intake pipelines.
