[0029] Embodiment One

[0030] Figure 1 is a flow chart of a vehicle air conditioning control method provided by the first embodiment of the present application, and the present embodiment can be applied to the case of controlling the operation of the air conditioner in the vehicle. The method can be executed by a vehicle air conditioning control device, which can be realized in the form of software and / or hardware, and can be configured in an electronic device carrying the vehicle air conditioning control function.

[0031] Referring to Figure 1 the vehicle air conditioning control method shown in the figure, which is applied to an air conditioning control system, comprising:

[0032] S110, acquire vehicle environment data of the current vehicle; wherein the vehicle environment data comprises a target control temperature, a vehicle internal temperature and an in-vehicle sunlight amount.

[0033] The current vehicle refers to a vehicle that needs to be controlled by the vehicle air conditioner at the current time. The type of the current vehicle is not limited in the embodiment of the application, and can be set by the technical personnel according to experience. The vehicle environment data refers to the environment-related data of the current vehicle.

[0034] The target control temperature refers to a temperature that needs to be reached by the air conditioner. For example, the target control temperature can be a temperature set by a person in the current vehicle according to demand. In the embodiment of the application, the target control temperature set by the user can be acquired through a man-machine interface on the current vehicle.

[0035] The vehicle internal temperature refers to the temperature inside the current vehicle. For example, the vehicle internal temperature can be acquired through an indoor temperature sensor.

[0036] The in-vehicle sunlight amount can be used to quantify the light intensity inside the current vehicle. For example, the in-vehicle sunlight amount can be acquired through a sunlight sensor.

[0037] The air conditioner control system refers to a system for controlling the operation of the air conditioner in the vehicle. For example, the air conditioner control system can comprise a data acquisition subsystem, an initial temperature determination subsystem, a compensation temperature determination subsystem, a target temperature determination subsystem and an operation control subsystem.

[0038] The data acquisition subsystem can be used to acquire the vehicle environment data of the current vehicle at the current time.

[0039] Specifically, the vehicle environment data of the current vehicle at the current time is acquired through the data acquisition subsystem.

[0040] S120, determine an initial air outlet temperature according to the vehicle environment data and a preset load coefficient.

[0041] The preset load coefficient refers to a preset calculation coefficient of the vehicle environment data. For example, the preset load coefficient can be used to eliminate the dimension and difference between the vehicle environment data to determine the initial air outlet temperature.

[0042] The initial air outlet temperature refers to the air outlet temperature of the air conditioner in the current vehicle determined without temperature compensation.

[0043] Specifically, the initial air outlet temperature is determined by the initial temperature determination subsystem according to the vehicle environment data and the preset load coefficient. The initial temperature determination subsystem can be used to determine the initial air outlet temperature.

[0044] S130, determining a temperature difference value according to the target control temperature and the vehicle interior temperature, and determining a target compensation temperature according to the temperature difference value and a preset temperature compensation parameter.

[0045] The temperature difference value refers to a difference between the target control temperature and the vehicle interior temperature.

[0046] For example, the temperature difference value can be determined by the following formula:

[0047] ΔT = T set -T r ;

[0048] The ΔT represents the temperature difference value; the T set represents the target control temperature; and the T r represents the vehicle interior temperature.

[0049] The temperature compensation parameter refers to a parameter used for temperature compensation. The target compensation temperature can be used to compensate the initial air outlet temperature.

[0050] For example, the temperature compensation parameter includes a temperature compensation P parameter, a temperature compensation I parameter, and a temperature compensation D parameter.

[0051] The temperature compensation P parameter can be understood as a temperature compensation proportional parameter, which refers to temperature compensation from the proportional dimension. The temperature compensation I parameter can be understood as a temperature compensation integral parameter, which refers to temperature compensation from the integral dimension. The temperature compensation D parameter can be understood as a temperature compensation differential parameter, which refers to temperature compensation from the differential dimension.

[0052] In an optional embodiment, determining the target compensation temperature according to the temperature difference value and the preset temperature compensation parameter includes: determining a P parameter control temperature compensation value according to the temperature compensation P parameter and the temperature difference value; determining an I parameter control temperature compensation value according to the temperature compensation I parameter and an integral value of the temperature difference value; determining a D parameter control temperature compensation value according to the temperature compensation D parameter and a derivative value of the temperature difference value; and determining the target compensation temperature according to the P parameter control temperature compensation value, the I parameter control temperature compensation value, and the D parameter control temperature compensation value.

[0053] The P parameter control temperature compensation value refers to a temperature compensation value determined from the proportional dimension. The I parameter control temperature compensation value refers to a temperature compensation value determined from the integral dimension. The D parameter control temperature compensation value refers to a temperature compensation value determined from the differential dimension.

[0054] Specifically, a sum value among the P parameter control temperature compensation value, the I parameter control temperature compensation value, and the D parameter control temperature compensation value is taken as the target compensation temperature.

[0055] Exemplarily, the target compensation temperature can be determined by the following formula:

[0056] T PID = T P + T I + T D ;

[0057] T P = K P * ΔT;

[0058]

[0059] wherein, T PID represents the target compensation temperature; T P represents the P parameter control temperature compensation value; T I represents the I parameter control temperature compensation value; T D represents the D parameter control temperature compensation value; K P represents the temperature compensation P parameter; K I represents the temperature compensation I parameter; represents the integral value of the temperature difference; K D represents the temperature compensation D parameter; represents the derivative value of the temperature difference.

[0060] It can be understood that by introducing the temperature compensation P parameter, the temperature compensation I parameter and the temperature compensation D parameter, the corresponding P parameter control temperature compensation value, the I parameter control temperature compensation value and the D parameter control temperature compensation value are determined, and then the target compensation temperature is determined, so as to realize the determination of the partial temperature compensation value from multiple dimensions, and improve the accuracy and reliability of the determined target compensation temperature.

[0061] Specifically, the compensation temperature determination subsystem determines the temperature difference according to the target control temperature and the vehicle interior temperature, and determines the target compensation temperature according to the temperature difference and the preset temperature compensation parameter. The compensation temperature determination subsystem can be used to determine the target compensation temperature.

[0062] S140, determining the target air outlet temperature according to the initial air outlet temperature and the target compensation temperature, and controlling the air conditioner in the current vehicle to operate according to the target air outlet temperature.

[0063] The target air outlet temperature refers to the temperature actually controlling the operation of the air conditioner in the current vehicle.

[0064] In an optional embodiment, the target control temperature is determined according to the initial air outlet temperature and the target compensation temperature, including: taking the sum value between the initial air outlet temperature and the target compensation temperature as the target air outlet temperature.

[0065] Exemplarily, the target air outlet temperature can be determined by the following formula:

[0066] T CO =T PID +T bf ;

[0067] Wherein, T CO represents the target air outlet temperature; T bf represents the initial air outlet temperature.

[0068] It can be understood that by taking the sum value between the initial air outlet temperature and the target compensation temperature as the target air outlet temperature, the temperature compensation of the initial air outlet temperature is realized, and the accuracy of the determined target air outlet temperature is improved.

[0069] Specifically, the target temperature determination subsystem determines the target air outlet temperature according to the initial air outlet temperature and the target compensation temperature; and the operation control subsystem controls the air conditioner in the current vehicle to operate according to the target air outlet temperature. The target temperature determination subsystem can be used to determine the target air outlet temperature. The operation control subsystem can be used to control the air conditioner to operate according to the target air outlet temperature.

[0070] The embodiment of the present application provides a vehicle air conditioner control scheme, which obtains vehicle environment data of a current vehicle; wherein the vehicle environment data includes a target control temperature, a vehicle internal temperature and an amount of sunlight in the vehicle; determines an initial air outlet temperature according to the vehicle environment data and a preset load coefficient; determines a temperature difference value according to the target control temperature and the vehicle internal temperature, and determines a target compensation temperature according to the temperature difference value and a preset temperature compensation parameter; determines a target air outlet temperature according to the initial air outlet temperature and the target compensation temperature, and controls the air conditioner in the current vehicle to operate according to the target air outlet temperature. The above scheme determines the target air outlet temperature according to the initial air outlet temperature and the target compensation temperature, and controls the air conditioner to operate according to the target air outlet temperature, so as to realize the compensation of the air outlet temperature, improve the accuracy of the determined target air outlet temperature, and further improve the accuracy of the automatic control of the air conditioner in the vehicle.

[0071] Embodiment two

[0072] Figure 2Ais a flow chart of a vehicle air conditioning control method provided by Embodiment Two of the present application. Based on the above-mentioned embodiments, the operation of "determining an initial air outlet temperature according to vehicle environment data and a preset load coefficient" is further refined into "determining a target temperature value according to a target refrigeration load coefficient and a target control temperature; determining an indoor temperature value according to an indoor heat load coefficient and an indoor temperature of the vehicle; determining an indoor illumination value according to an illumination heat load coefficient and an amount of sunlight in the vehicle; and determining an initial air outlet temperature according to the target temperature value, the indoor temperature value, and the indoor illumination value", so as to improve the determination mechanism of the initial air outlet temperature. It should be noted that the parts not described in detail in Embodiment Two of the present application can be referred to the descriptions of other embodiments.

[0073] Referring to Figure 2A The vehicle air conditioning control scheme shown in the figure comprises:

[0074] S210, obtaining vehicle environment data of a current vehicle; wherein the vehicle environment data comprises a target control temperature, an indoor temperature of the vehicle, and an amount of sunlight in the vehicle.

[0075] S220, determining a target temperature value according to a target refrigeration load coefficient and the target control temperature.

[0076] The target refrigeration load coefficient refers to a constant of a refrigeration load required by a person in the current vehicle. For example, the target refrigeration load coefficient can be determined by calibration. The target temperature value refers to a temperature value obtained by processing the target control temperature by the target refrigeration load coefficient. For example, the product of the target refrigeration load coefficient and the target control temperature is taken as the target temperature value.

[0077] S230, determining an indoor temperature value according to an indoor heat load coefficient and the indoor temperature of the vehicle.

[0078] The indoor heat load coefficient refers to a constant of an indoor heat load. For example, the indoor heat load coefficient can be determined by calibration. The indoor temperature value refers to a temperature value obtained by processing the indoor temperature of the vehicle by the indoor heat load coefficient. For example, the product of the indoor heat load coefficient and the indoor temperature of the vehicle is taken as the indoor temperature value.

[0079] S240, determining an indoor illumination value according to an illumination heat load coefficient and the amount of sunlight in the vehicle.

[0080] The illumination heat load coefficient refers to a constant of an illumination heat load. For example, the illumination heat load coefficient can be determined by calibration. The indoor illumination value refers to an illumination value obtained by processing the amount of sunlight in the vehicle by the illumination heat load coefficient. For example, the product of the illumination heat load coefficient and the amount of sunlight in the vehicle is taken as the indoor illumination value.

[0081] It should be noted that the target refrigeration load coefficient, the in-vehicle heat load coefficient and the light heat load coefficient in the embodiment of the present application can be used to unify or eliminate the dimensions of the corresponding target control temperature, the in-vehicle temperature and the in-vehicle sunlight amount, to obtain a target temperature value, an in-vehicle temperature value and an in-vehicle light value, thereby avoiding the differences between the target control temperature, the in-vehicle temperature and the in-vehicle sunlight amount.

[0082] In S250, an initial air outlet temperature is determined according to the target temperature value, the in-vehicle temperature value and the in-vehicle light value.

[0083] In one optional embodiment, the initial air outlet temperature is determined according to the target temperature value, the in-vehicle temperature value and the in-vehicle light value, including: determining a reference air outlet temperature value according to the target temperature value, the in-vehicle temperature value and the in-vehicle light value; and determining the initial air outlet temperature according to a preset air outlet temperature compensation value and the reference air outlet temperature value.

[0084] The reference air outlet temperature value refers to a temperature value obtained without compensating the target temperature value, the in-vehicle temperature value and the in-vehicle light value. The preset air outlet temperature compensation value can be used to compensate the error of the reference air outlet temperature value.

[0085] For example, the reference air outlet temperature value = target temperature value - in-vehicle temperature value - in-vehicle light value.

[0086] For example, the initial air outlet temperature can be determined by the following formula:

[0087] T bf = K set × T set - K r × T r - K s × T s + KC

[0088] Wherein, T bf represents the initial air outlet temperature; K set represents the target refrigeration load coefficient; T set represents the target control temperature; K r represents the in-vehicle heat load coefficient; T r represents the in-vehicle temperature; K s represents the light heat load coefficient; T s represents the in-vehicle sunlight amount; and KC represents the preset air outlet temperature compensation value.

[0089] It can be understood that errors may occur in the process of calculating the target temperature value, the in-vehicle temperature value and the in-vehicle light value, resulting in inaccurate reference air outlet temperature value. Therefore, the preset air outlet temperature compensation value is introduced to compensate the reference air outlet temperature value, to obtain the initial air outlet temperature.

[0090] S260, determining a temperature difference value according to the target control temperature and the vehicle interior temperature, and determining a target compensation temperature according to the temperature difference value and a preset temperature compensation parameter.

[0091] S270, determining a target air outlet temperature according to the initial air outlet temperature and the target compensation temperature, and controlling the air conditioner in the current vehicle to operate according to the target air outlet temperature.

[0092] The vehicle air conditioner control scheme provided by the embodiment of the present application refines the operation of determining the initial air outlet temperature according to the vehicle environment data and the preset load coefficient into the operation of determining a target temperature value according to a target refrigeration load coefficient and a target control temperature, determining a vehicle interior temperature value according to a vehicle interior heat load coefficient and a vehicle interior temperature, determining a vehicle interior illumination value according to an illumination heat load coefficient and a vehicle interior sunlight amount, and determining the initial air outlet temperature according to the target temperature value, the vehicle interior temperature value and the vehicle interior illumination value, thereby improving the determination mechanism of the initial air outlet temperature. The above scheme introduces the target refrigeration load coefficient, the vehicle interior heat load coefficient and the illumination heat load coefficient, eliminates the difference between the target control temperature, the vehicle interior temperature and the vehicle interior sunlight amount, so that the target temperature value, the vehicle interior temperature value and the vehicle interior illumination value can be operated to obtain the initial air outlet temperature, and the accuracy and reliability of the determined initial air outlet temperature are improved.

[0093] On the basis of the above technical scheme, the embodiment of the present application further provides a commercial vehicle automatic air conditioner control method based on target temperature calculation. In the prior art, a perfect air conditioner system controlled by a computer of an automobile can automatically adjust the temperature, air volume and air direction of air in the vehicle, provide a good vehicle environment for passengers, and ensure that the passengers are in a comfortable air environment under various external climates and conditions. The embodiment of the present application proposes an air conditioner target temperature control algorithm based on feedforward compensation PID, which can accurately control the temperature of the air conditioner system.

[0094] For example, the air conditioner control system in the embodiment of the present application takes the control subsystem as the core subsystem, needs to take the vehicle environment data at the current time given by the input subsystem (i.e. the data acquisition subsystem) as the system input, accurately control the target air outlet temperature according to the temperature accurate control algorithm, and control the output subsystem (i.e. the air conditioner control system). The output subsystem feeds back the vehicle environment data at the next time to the input subsystem and the control subsystem, to form the temperature closed-loop accurate control of the air conditioner system. The commercial vehicle automatic air conditioner control method based on target temperature calculation takes the air conditioner target temperature control algorithm based on feedforward compensation PID (proportional, integral, derivative) as the target temperature core control algorithm.

[0095] The control subsystem can include an initial temperature determination subsystem, a compensation temperature determination subsystem and a target temperature determination subsystem.

[0096] The running control subsystem can include a mode damper motor, a circulation damper motor, a mixed damper motor, a compressor, a defrosting motor, independent cooling air, independent cooling air and intelligent control, etc.

[0097] An exemplary air conditioner target temperature control algorithm based on feedforward compensation PID includes two subsystems. The first subsystem is a feedforward control initial outlet air temperature calculation subsystem (i.e., an initial temperature determination subsystem). This module calculates the initial outlet air temperature through the feedforward control principle and vehicle environment data obtained by the input subsystem. The second subsystem is a PID control subsystem (i.e., a compensation temperature determination subsystem) that calculates the compensation temperature through PID. The temperature values calculated by the two subsystems are added to obtain the control temperature (i.e., the target outlet air temperature) input by the actuator. The control temperature is given to the actuator (i.e., the running control subsystem) to accurately achieve closed-loop control of the air conditioner indoor temperature.

[0098] An exemplary air conditioner target temperature control algorithm based on feedforward compensation PID includes two subsystems. The first subsystem is a feedforward control initial outlet air temperature calculation subsystem (i.e., an initial temperature determination subsystem). This module calculates the initial outlet air temperature through the feedforward control principle and vehicle environment data obtained by the input subsystem. The second subsystem is a PID control subsystem (i.e., a compensation temperature determination subsystem) that calculates the compensation temperature through PID.

The control temperature is given to the actuator (i.e., the running control subsystem) to accurately achieve closed-loop control of the air conditioner indoor temperature. Figure 2B The flowchart of the vehicle air conditioner control method based on the air conditioner control system is shown. The data acquisition subsystem obtains vehicle environment data; the initial temperature determination subsystem obtains the initial outlet air temperature according to the input vehicle environment data; the compensation temperature determination subsystem determines the target compensation temperature according to the input vehicle environment data; the target temperature determination subsystem adds the initial outlet air temperature and the target compensation temperature to obtain the target outlet air temperature; and the running control subsystem controls the air conditioner to run according to the target outlet air temperature and feeds back the vehicle internal temperature to the data acquisition subsystem in real time.
