Description

Technical Field

[0001] This application relates to the field of dual-mode air conditioning control technology, and in particular to a dual-mode air conditioning control method, system, equipment and medium for commercial vehicles. Background Technology

[0002] Dual-mode air conditioning for commercial vehicles refers to an air conditioning system with two operating modes. It features manual control logic for both modes, typically a manual control scheme that eliminates the need for a mechanical compressor to disconnect temperature regulation and an electric compressor to regulate cooling capacity. This system can automatically switch the air conditioning's operating mode based on the vehicle's status (such as driving or parking) and environmental conditions (such as interior temperature and battery voltage) to meet cooling needs in different scenarios.

[0003] Currently, the switching scheme for dual-mode air conditioning in commercial vehicles mainly involves: obtaining the vehicle's battery voltage, and based on the obtained battery voltage: when the battery voltage is lower than the preset voltage, controlling the engine and driving air conditioning to be in working state, and the parking air conditioning to be in off state; when the battery voltage is not lower than the preset voltage, if the engine is in working state, controlling the driving air conditioning to be in starting state, and the parking air conditioning to be in off state; if the engine is in off state, controlling the driving air conditioning to be in off state, and the parking air conditioning to be in starting state.

[0004] However, in actual operation, the above solution requires manual adjustment of the air conditioning according to actual needs in order to adapt to the constantly changing external environment. During the adjustment process, improper human adjustment may lead to insufficient cooling, which in turn triggers the refrigeration system, as well as the problem that the air conditioning cooling inverter control is not implemented when the vehicle is parked.

[0024] The technical solutions proposed in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] This application provides a method for controlling a dual-mode air conditioning system in a commercial vehicle, such as... Figure 1 As shown in the embodiments of this application, the method mainly includes the following steps:

[0026] Step 110: Based on the auxiliary power supply status and engine speed, determine the current operating mode, and then determine the operating compressor corresponding to the air conditioner.

[0027] This step can be specifically described as follows:

[0028] When the auxiliary power supply is off, the current operating mode is set to parking mode. When the air conditioning starts cooling, the corresponding operating compressor is set to an electric compressor.

[0029] When the auxiliary power supply is powered on, the engine speed is acquired; when the engine speed is greater than the preset value, the current operating mode is determined to be driving mode, and the operating compressor corresponding to the air conditioner is determined to be a mechanical compressor.

[0030] If the engine fails to reach the preset normal speed after starting, the current operating mode is set to start-up protection mode, and the compressor is not started.

[0031] When the engine speed is 0, the current operating mode is determined to be parking mode. When the air conditioning starts cooling, the corresponding operating compressor for the air conditioning is determined to be an electric compressor.

[0032] Step 120: Obtain the current preset temperature, internal temperature, and air conditioner blower setting.

[0033] Step 130: When the current operating mode is driving mode and the cooling is started, determine the disconnection temperature corresponding to the running compressor based on the current preset temperature, internal temperature, and air conditioning blower setting.

[0034] This step can be specifically described as follows:

[0035] When the air conditioner blower is set to fan speed level one or two, and (internal temperature - preset temperature) ≤ first set temperature, the disconnection temperature corresponding to the running compressor is determined as the first target temperature.

[0036] When the air conditioner blower fan speed setting is one or two, and (internal temperature - preset temperature) > the first preset temperature, the disconnection temperature corresponding to the running compressor is determined as the second target temperature; when the air conditioner blower fan speed setting is three or five, and the first preset temperature < (internal temperature - preset temperature) ≤ the second preset temperature, the disconnection temperature corresponding to the running compressor is determined as the second target temperature; when the air conditioner blower fan speed setting is three or five, and (internal temperature - preset temperature) > the second preset temperature, the disconnection temperature corresponding to the running compressor is determined as the third target temperature; when the air conditioner blower fan speed setting is six or seven, and the second preset temperature < (internal temperature - preset temperature) ≤ the third preset temperature, the disconnection temperature corresponding to the running compressor is determined as the third target temperature; when the air conditioner blower fan speed setting is six or seven, and (internal temperature - preset temperature) > the third preset temperature, the disconnection temperature corresponding to the running compressor is determined as the fourth target temperature.

Furthermore, those skilled in the art can adjust the specific values ​​of the preset temperatures according to actual needs, and the first preset temperature is lower than the second preset temperature, and the second preset temperature is lower than the third preset temperature.

[0038] Step 140: When the current operating mode is parking mode and the cooling is started, determine the target temperature corresponding to the evaporator based on the air conditioning blower setting, and then determine the target speed of the compressor based on the difference between the current internal temperature and the target temperature.

[0039] Specifically, determining the target temperature of the evaporator based on the air conditioner blower setting can be done as follows:

[0040] When the air conditioner blower fan speed setting is at level 1, the target evaporator temperature is the fifth target temperature; when the air conditioner blower fan speed setting is at level 2, the target evaporator temperature is the sixth target temperature; when the air conditioner blower fan speed setting is at level 3, the target evaporator temperature is the seventh target temperature; and when the air conditioner blower fan speed setting is at level 4, the target evaporator temperature is the eighth target temperature.

[0041] Specifically, the target operating speed of the compressor is determined based on the difference between the current internal temperature and the target temperature. This can be achieved by:

[0042] The preset adjustment relationship between the difference and the target speed is obtained, and then the target speed of the compressor is determined based on the difference; where the larger the difference, the larger the target speed.

[0050] When the air conditioner blower is set to fan speed level 3 to 5, and (internal temperature - preset temperature) > second preset temperature, the disconnection temperature corresponding to the running compressor is determined to be the third target temperature.

[0051] When the air conditioner blower is set to fan speed level six or seven, and the second preset temperature < (internal temperature - preset temperature) ≤ the third preset temperature, the disconnection temperature corresponding to the running compressor is determined to be the third target temperature.
