[0028] At present, most commercial vehicle air conditioners at home and abroad are manual air conditioners. Automatic air conditioners have the advantage of adaptive control in temperature regulation. At the same time, automatic air conditioners control temperature more accurately and can accurately adjust the temperature of the entire vehicle to better adapt to the ambient temperature inside the vehicle.

[0029] Embodiment 1

[0030] Figure 1 This is a flow chart of a vehicle air conditioning control method provided in Example 1 of the present invention. This embodiment can be applied to controlling the operation of the air conditioning in a vehicle. The method can be executed by a vehicle air conditioning control device, which can be implemented in software and / or hardware and can be configured in an electronic device that carries the vehicle air conditioning control function.

[0031] See also Figure 1 The vehicle air conditioning control method shown is applied to an air conditioning control system, comprising:

[0032] S110, obtaining vehicle environment data of the current vehicle; wherein the vehicle environment data includes a target control temperature, a vehicle interior temperature, and an amount of sunlight inside the vehicle.

[0033] The current vehicle refers to the vehicle that needs to be controlled by the vehicle air conditioner at the current moment. The embodiment of the present invention does not limit the type of the current vehicle, and the type can be set by the technician based on experience. The vehicle environment data refers to the environment-related data of the current vehicle.

[0034] The target control temperature refers to the pre-set temperature that the air conditioner needs to reach. 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 present invention, the target control temperature set by the user can be obtained through the human-computer interaction interface on the current vehicle.

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

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

[0037] The air conditioning control system refers to a system for controlling the operation of the air conditioning in the vehicle. Exemplarily, the air conditioning control system may include 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] Among them, the data acquisition subsystem can be used to obtain the vehicle environment data of the current vehicle at the current moment.

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

[0040] S120: Determine an initial air outlet temperature according to vehicle environment data and a preset load factor.

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

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

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

[0046] Exemplarily, the temperature difference may be determined by the following formula:

[0047] ΔT=T set -T r ;

[0048] Where ΔT represents the temperature difference; T set Indicates the target control temperature; T r Indicates the vehicle's interior temperature.

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

[0050] Exemplarily, the temperature compensation parameters include a temperature compensation P parameter, a temperature compensation I parameter, and a temperature compensation D parameter.

[0051] Among them, the temperature compensation P parameter can be understood as the temperature compensation proportional parameter, which means temperature compensation is performed from the proportional dimension. The temperature compensation I parameter can be understood as the temperature compensation integral parameter, which means temperature compensation is performed from the integral dimension. The temperature compensation D parameter can be understood as the temperature compensation differential parameter, which means temperature compensation is performed from the differential dimension.

[0052] In an optional embodiment, the target compensation temperature is determined according to the temperature difference and the preset temperature compensation parameters, including: determining the P parameter controlled temperature compensation value according to the temperature compensation P parameter and the temperature difference; determining the I parameter controlled temperature compensation value according to the temperature compensation I parameter and the integral value of the temperature difference; determining the D parameter controlled temperature compensation value according to the temperature compensation D parameter and the derivative value of the temperature difference; determining the target compensation temperature according to the P parameter controlled temperature compensation value, the I parameter controlled temperature compensation value and the D parameter controlled temperature compensation value.

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

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

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

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

[0057] T P =K P ×ΔT;

[0058]

[0059] Among them, T PID Indicates the target compensation temperature; T P Indicates the P parameter controls the temperature compensation value; T I Indicates the temperature compensation value controlled by the I parameter; T D Indicates the temperature compensation value controlled by the D parameter; K P Indicates the temperature compensation P parameter; K I Indicates the temperature compensation I parameter; Indicates the integral value of the temperature difference; K D Indicates the temperature compensation D parameter; Represents the derivative 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-controlled temperature compensation value, the I parameter-controlled temperature compensation value and the D parameter-controlled temperature compensation value are determined, and then the target compensation temperature is determined, thereby realizing the determination of partial temperature compensation values ​​from multiple dimensions, and improving 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: Determine a target air outlet temperature according to the initial air outlet temperature and the target compensation temperature, and control the operation of the air conditioner in the current vehicle according to the target air outlet temperature.

[0063] The target air outlet temperature refers to the temperature that actually controls 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 of the initial air outlet temperature and the target compensation temperature as the target air outlet temperature.

[0065] For example, the target air outlet temperature may be determined by the following formula:

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

[0067] Among them, T CO Indicates the target outlet air temperature; T bf Indicates the initial outlet air temperature.

[0068] It can be understood that by taking the sum of the initial air outlet temperature and the target compensation temperature as the target air outlet temperature, temperature compensation for the initial air outlet temperature is achieved, thereby improving the accuracy of the determined target air outlet temperature.

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

[0070] The embodiment of the present invention provides a vehicle air conditioning control scheme, which obtains the vehicle environment data of the current vehicle; wherein the vehicle environment data includes the target control temperature, the vehicle interior temperature and the amount of sunlight in the vehicle; determines the initial air outlet temperature according to the vehicle environment data and the preset load factor; 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; determines the target air outlet temperature according to the initial air outlet temperature and the target compensation temperature, and controls the air conditioning operation in the current vehicle according to the target air outlet temperature. The above scheme realizes compensation for the air outlet temperature by determining the target air outlet temperature according to the initial air outlet temperature and the target compensation temperature, and controls the air conditioning operation according to the target air outlet temperature, thereby improving the accuracy of the determined target air outlet temperature, and thus improving the accuracy of the automatic control of the air conditioning in the vehicle.

[0071] Embodiment 2

[0072] Figure 2AIt is a flow chart of a vehicle air conditioning control method provided in the second embodiment of the present invention. Based on the above embodiments, this embodiment further refines the operation of "determining the initial air outlet temperature according to the vehicle environmental data and the preset load factor" into "determining the target temperature value according to the target cooling load factor and the target control temperature; determining the in-vehicle temperature value according to the in-vehicle heat load factor and the vehicle's internal temperature; determining the in-vehicle light value according to the light heat load factor and the amount of sunlight in the vehicle; determining the initial air outlet temperature according to the target temperature value, the in-vehicle temperature value and the in-vehicle light value" to improve the mechanism for determining the initial air outlet temperature. It should be noted that for the parts not described in detail in the embodiments of the present invention, reference may be made to the descriptions of other embodiments.

[0073] See also Figure 2A The vehicle air conditioning control scheme shown includes:

[0074] S210, obtaining vehicle environment data of the current vehicle; wherein the vehicle environment data includes a target control temperature, a vehicle interior temperature, and an amount of sunlight inside the vehicle.

[0075] S220: Determine a target temperature value according to a target cooling load factor and a target control temperature.

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

[0077] S230: Determine the vehicle interior temperature value according to the vehicle interior heat load coefficient and the vehicle interior temperature.

[0078] The in-vehicle heat load coefficient refers to the in-vehicle heat load constant. For example, the in-vehicle heat load coefficient can be determined by calibration. The in-vehicle temperature value refers to the temperature value obtained by processing the in-vehicle heat load coefficient on the vehicle interior temperature. For example, the product of the in-vehicle heat load coefficient and the vehicle interior temperature is used as the in-vehicle temperature value.

[0079] S240: Determine the lighting value inside the vehicle according to the lighting heat load coefficient and the amount of sunlight inside the vehicle.

[0080] Wherein, the light heat load coefficient refers to the light heat load constant. Exemplarily, the light heat load coefficient can be determined by calibration. The in-vehicle light value refers to the light value obtained by processing the light heat load coefficient with the amount of sunlight in the vehicle. Exemplarily, the product of the light heat load coefficient and the amount of sunlight in the vehicle is used as the in-vehicle light value.

[0081] It should be noted that the target cooling load coefficient, in-vehicle heat load coefficient and lighting heat load coefficient in the embodiments of the present invention can be used to unify or eliminate the dimensions of the corresponding target control temperature, vehicle interior temperature and vehicle interior sunlight amount, respectively, to obtain the target temperature value, vehicle interior temperature value and vehicle interior sunlight value, thereby avoiding the differences between the target control temperature, vehicle interior temperature and vehicle interior sunlight amount.

[0082] S250: Determine an initial air outlet temperature according to a target temperature value, an interior temperature value, and an interior light value.

[0083] In an optional embodiment, the initial outlet air temperature is determined based on the target temperature value, the interior temperature value and the interior light value, including: determining a reference outlet air temperature value based on the target temperature value, the interior temperature value and the interior light value; determining the initial outlet air temperature based on a preset outlet air temperature compensation value and the reference outlet air temperature value.

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

[0085] Exemplarily, the reference air outlet temperature value=target temperature value-interior temperature value-interior light value.

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

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

[0088] Among them, T bf Indicates the initial outlet air temperature; K set represents the target cooling load factor; T set Indicates the target control temperature; K r Indicates the heat load coefficient in the vehicle; T r Indicates the vehicle's internal temperature; K s Indicates the light heat load coefficient; T s Indicates the amount of sunlight in the car; KC indicates the preset air outlet temperature compensation value.

[0089] It is understandable that errors may occur in the process of calculating the target temperature value, the interior temperature value and the interior light value, resulting in an inaccurate reference outlet air temperature value. Therefore, a preset outlet air temperature compensation value is introduced to compensate the reference outlet air temperature value to obtain the initial outlet air temperature.

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

[0091] S270: Determine a target air outlet temperature according to the initial air outlet temperature and the target compensation temperature, and control the operation of the air conditioner in the current vehicle according to the target air outlet temperature.

[0092] The embodiment of the present invention provides a vehicle air conditioning control scheme, which refines the operation of determining the initial air outlet temperature according to the vehicle environmental data and the preset load coefficient into determining the target temperature value according to the target cooling load coefficient and the target control temperature; determining the in-vehicle temperature value according to the in-vehicle heat load coefficient and the in-vehicle temperature; determining the in-vehicle light value according to the light heat load coefficient and the in-vehicle sunlight; and determining the initial air outlet temperature according to the target temperature value, the in-vehicle temperature value and the in-vehicle light value, thereby improving the mechanism for determining the initial air outlet temperature. The above scheme, by introducing the target cooling load coefficient, the in-vehicle heat load coefficient and the light heat load coefficient, eliminates the differences between the target control temperature, the in-vehicle temperature and the in-vehicle sunlight, so that the obtained target temperature value, the in-vehicle temperature value and the in-vehicle light value can be operated to obtain the initial air outlet temperature, thereby improving the accuracy and reliability of the determined initial air outlet temperature.

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

[0094] Exemplarily, in the air conditioning control system of the embodiment of the present invention, the control subsystem is the core subsystem, which needs to use the vehicle environment data at the current moment 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 precision control algorithm, and control the output subsystem (i.e., the air conditioning control system), and the output subsystem feeds back the vehicle environment data at the next moment to the input subsystem and the control subsystem, forming a closed-loop precise control of the air conditioning system temperature. A commercial vehicle automatic air conditioning control method based on target temperature calculation, whose target temperature core control algorithm is an air conditioning target temperature control algorithm based on feedforward compensation PID (proportional, integral, derivative).

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

[0096] Exemplarily, the operation control subsystem may include a mode damper motor, a circulation damper motor, a mixing damper motor, a compressor, a defrost motor, independent cooling, independent cooling and intelligent control, etc.

[0097] For example, an air conditioning 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., initial temperature determination subsystem). This module calculates the initial outlet air temperature through the feedforward control principle and the vehicle environment data obtained by the input subsystem. The second subsystem is a PID control subsystem (i.e., compensation temperature determination subsystem). The compensation temperature is calculated by PID. The temperature values ​​calculated by the two subsystems are added together to obtain the control temperature (i.e., target outlet air temperature) that needs to be input by the actuator. The control temperature is given to the actuator (i.e., the operation control subsystem) to accurately realize the closed-loop control of the indoor temperature of the air conditioner.

[0098] For example, see Figure 2B The flowchart of the vehicle air conditioning control method based on the air conditioning control system is shown. Among them, the data acquisition subsystem obtains vehicle environmental data; the initial temperature determination subsystem obtains the initial air outlet temperature according to the input vehicle environmental data; the compensation temperature determination subsystem determines the target compensation temperature according to the input vehicle environmental data; the target temperature determination subsystem adds the initial air outlet temperature and the target compensation temperature to obtain the target air outlet temperature; the operation control subsystem controls the air conditioning operation according to the target air outlet temperature, and feeds back the vehicle internal temperature to the data acquisition subsystem in real time.
