[0028] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0029] Figure 1A This is a flow chart of a vehicle air conditioning system provided by an embodiment of the present invention. This embodiment is applicable to the automatic control scenario of vehicle air conditioning operation.

[0030] like Figure 1A As shown, the structure of the vehicle air conditioning system of this embodiment includes:

[0031] Water valve, heater core, sunlight sensor, temperature sensor, fan, mode motor, compressor, deflector and air conditioner outlet control device.

[0032] The water valve can be a solenoid-controlled valve that regulates the flow of engine coolant into the heater core, controlling the heating capacity (operating in heating mode only). The heater core acts like a radiator, heating the air as coolant flows through it, achieving either heating or demisting functions. The air volume is determined by the fan speed. A sunlight sensor can be mounted above the instrument panel to detect light intensity, automatically increasing cooling capacity in strong sunlight to offset the effects of direct sunlight. Temperature sensors can include those located inside and outside the vehicle, as well as at the evaporator (thermistor type) and at various locations on the air outlet. These sensors sense the temperature at various locations and subsequently serve as parameters for adjusting the air conditioning operating state, for example, to adjust compressor displacement and fan speed. The mode motor can be driven by a stepper motor and receive signals from the electronic control unit to support switching between multiple air conditioning operating modes or linkage (e.g., face blowing + demisting). The fan can force air through the evaporator (cooling) or the heater core (heating), creating hot and cold air flows that are delivered to the vehicle interior.

[0033] In particular, in this embodiment, the vehicle air conditioning system is provided with a deflector. The deflector can be provided at the air outlet of the vehicle air conditioning system to guide the wind from the high temperature area of ​​the air outlet to the low temperature area of ​​the air outlet. For example, Figure 1B As shown, the high-temperature area of ​​the air outlet corresponds to the driver's seat outlet, and the low-temperature area corresponds to the passenger seat outlet. When adjusting the air conditioning outlet temperature by regulating the water flow entering the heater core through a water valve, due to space limitations, there is no mixing space in the air conditioning cabinet. This leads to uneven air outlet temperature during spring and autumn operating conditions when water flow demand is low.

[0034] Accordingly, the temperature difference at the air outlet can be reduced by guiding the air from the high temperature area to the low temperature area through the guide plate. Figure 1CThe pink plate shown in the figure is the deflector. Furthermore, based on the addition of a deflector to the vehicle air conditioning system, the air conditioning outlet control device can obtain the air conditioning set temperature value, the sensing value of the sunlight sensor, and the vehicle interior temperature, vehicle exterior temperature, outlet high temperature zone temperature, and outlet low temperature zone temperature collected by temperature sensors set at different locations; and then determine the water valve opening, fan gear, and compressor operating status based on the air conditioning set temperature value, sensing value, vehicle interior temperature, vehicle exterior temperature, outlet high temperature zone temperature, and outlet low temperature zone temperature, so that the temperature difference between the outlet high temperature zone temperature and the outlet low temperature zone temperature is within the preset temperature difference range. Among them, the air conditioning set temperature can be a temperature value input by the driver and passengers in the vehicle through voice, air conditioning control panel, or remote control, etc., as the target temperature value for air conditioning temperature adjustment.

[0035] Specifically, the air-conditioning air outlet control device may determine the working mode of the mode motor according to the temperature inside the vehicle to determine the blowing mode of the vehicle air-conditioning system; determine the working gear of the fan in the blowing mode according to the air-conditioning set temperature value; determine the open or closed state of the water valve according to the temperature difference between the air-conditioning set temperature and the outside temperature, the sensing value, and the temperature of the high-temperature zone and the low-temperature zone of the air outlet; determine the open or closed state of the compressor according to the working gear and the air-conditioning temperature setting value.

[0036] In vehicle air conditioning systems, the fan's operating position can be controlled by its "duty cycle," a parameter used by the electronic control unit to control the fan motor's speed via a PWM (Pulse Width Modulation) signal. By varying the PWM signal's duty cycle, the average input voltage to the fan motor is adjusted, thereby controlling the fan's speed and, in turn, adjusting the air volume delivered to each outlet (including the damper).

[0037] Especially for low-flow and low-wind speed scenarios, the corresponding relationship between water valve opening and wind speed can be determined based on the target outlet temperature difference. That is, the required water valve opening and wind speed value are selected based on the outlet temperature difference. Natural air cooling and compressor cooling are simultaneously introduced to control the outlet air temperature. This improves outlet air temperature uniformity while maintaining a comfortable interior temperature for the human body. The target outlet temperature difference can be a pre-set value, such as a preset temperature difference range of 0-5 degrees Celsius.

[0038] Among them, when determining the open or closed state of the water valve, a table lookup method can be used, wherein the table object to be looked up is a preset water valve opening and closing temperature table. The preset water valve opening and closing temperature table (reference Table 1) can be queried based on the temperature difference between the air conditioner set temperature and the outside temperature of the vehicle, and the sensing value to determine the reference outlet temperature corresponding to opening or closing the water valve; based on the numerical relationship between the outlet high temperature zone temperature and the outlet low temperature zone temperature and the reference outlet temperature, the open or closed state of the water valve is determined. The numerical relationship between the outlet high temperature zone temperature and the outlet low temperature zone temperature and the reference outlet temperature can include the following situations: the reference outlet temperature is the outlet high temperature zone temperature or the outlet low temperature zone temperature; the reference outlet temperature is the average of the outlet high temperature zone temperature and the outlet low temperature zone temperature.

[0039] Table 1

[0040]

[0041] In an optional embodiment, when the temperature inside the vehicle is in the temperature range of 5-15 degrees Celsius, the working mode of the mode motor is determined to be the first working mode, so as to determine that the blowing mode of the vehicle air-conditioning system is the foot-blowing mode, that is, the first working mode corresponds to the foot-blowing mode. According to the mapping relationship between the set temperature and the duty cycle of the fan working signal, the duty cycle of the first fan working signal corresponding to the air-conditioning set temperature value is determined, and the fan gear corresponding to the duty cycle of the first fan working signal is determined as the working gear of the fan; wherein, the working gear is less than the preset working gear threshold. Specifically, when the temperature inside the vehicle (i.e., the ambient temperature) is in the temperature range of 5-15 degrees Celsius, the foot-blowing mode is adopted. When the air-conditioning set temperature value is not the lowest temperature, the maximum wind speed does not exceed the set upper limit wind speed. For example, the low wind speed range is 0-3 gears, and the upper limit wind speed is 3 gears. When the air-conditioning set temperature value is 22°C, the duty cycle of the low wind speed air volume control signal can exceed 20%. When the air conditioner set temperature is greater than 25℃, the duty cycle of the low wind speed air volume shall not exceed 15%. When the AUTO setting is above 28℃, the duty cycle of the low wind speed air volume shall exceed 10%. At this time, the compressor determines whether to turn on or off according to the specific situation. When the temperature value of the foot air outlet temperature sensor is greater than a certain temperature, the water valve is determined to be closed or opened according to the air outlet temperature value.

[0042] In an optional embodiment, when the vehicle interior temperature is between 15°C and 20°C, the air blowing mode of the vehicle air conditioning system is determined to be face blowing mode and / or foot blowing mode based on the air conditioning set temperature value. A second fan operating signal duty cycle matching the air conditioning set temperature value can be determined based on a mapping relationship between the set temperature and the fan operating signal duty cycle, and the fan gear corresponding to the second fan operating signal duty cycle is determined as the fan operating gear. Specifically, when the vehicle interior temperature (i.e., ambient temperature) is between 15°C and 20°C, and the air conditioning set temperature value is less than 20°C, the face blowing mode can be enabled and the compressor can be turned on. If the air conditioning set temperature value is greater than 20°C, whether to enable foot blowing can be determined based on the difference between the air conditioning set temperature and the vehicle interior temperature. If the air conditioning set temperature value is greater than 22°C, the low wind speed setting can be determined based on whether the compressor is on or off. If the air conditioning set temperature value is less than AUTO22°C and the compressor is on, the fan operating gear can be set to the first preset wind speed setting. When the compressor is off, the duty cycle of the fan control signal does not exceed 20%. When the air conditioner set temperature is 21℃, the fan control signal does not exceed 30%.

[0043] In an optional embodiment, when the vehicle interior temperature is between 20°C and 25°C, the vehicle air conditioning system's blowing mode is determined to be face blowing mode. The fan operating position is determined based on the air conditioning set temperature and the operating status of the compressor. Alternatively, based on a mapping relationship between the set temperature and the fan operating signal duty cycle, a third fan operating signal duty cycle matching the air conditioning set temperature is determined, and the fan operating position corresponding to the third fan operating signal duty cycle is determined as the fan operating position. Specifically, when the vehicle interior temperature is between 20°C and 25°C, the face blowing mode is adopted. When the air conditioning set temperature is greater than 22°C, the compressor is turned on and the air speed is determined to be within a preset low speed range. When the compressor is turned off, the air speed is determined to be within a preset low speed range. When the air conditioning set temperature is less than 22°C, the compressor is turned on, the water valve is closed, and the air speed is fixed to within the preset low speed range. When the compressor is off, the fan signal duty cycle is set to no more than 20%. When the air conditioning set temperature is AUTO 21°C, the fan signal duty cycle is set to no more than 30%. When the air conditioner is set to 20℃, the wind speed is preset to the low wind speed range. When the air conditioner is set to 19℃ or 18℃, the wind speed is set to the high wind speed range.

[0044] In other words, after the vehicle air conditioner is equipped with a deflector, an air conditioning control simulation can be performed to determine a mapping relationship table of the vehicle's indoor and outdoor temperatures, set temperature, wind gear setting, fan control signal duty cycle, compressor working status, water valve open or closed status, sunlight sensor sensing value, and outlet temperature difference. The mapping relationship table can contain multiple sub-tables, and the vehicle air conditioning system control strategy can be determined by looking up the table.

[0045] The technical solution of this embodiment comprises a vehicle air conditioning system comprising a water valve, a heater core, a sunlight sensor, a temperature sensor, a fan, a mode motor, a compressor, a deflector, and an air conditioning outlet control device. The deflector is disposed at the air outlet of the vehicle air conditioning system to divert air from the high-temperature zone of the outlet to the low-temperature zone of the outlet. The air conditioning outlet control device is configured to obtain the air conditioning set temperature value, the sensing value of the sunlight sensor, and the vehicle interior temperature, vehicle exterior temperature, and outlet high-temperature zone temperature and outlet low-temperature zone temperature collected by temperature sensors located at different locations. The control device is further configured to determine the water valve opening, the fan gear position, and the operating state of the compressor based on the air conditioning set temperature value, the sensing value, the vehicle interior temperature, vehicle exterior temperature, outlet high-temperature zone temperature, and outlet low-temperature zone temperature, so as to ensure that the temperature difference between the outlet high-temperature zone temperature and the outlet low-temperature zone temperature is within a preset temperature difference range. The technical solution of this embodiment of the present invention solves the problem of uneven air conditioning outlet temperature. With the addition of the deflector, the operating mode and air volume of the air conditioning can be adjusted according to the set temperature value to achieve uniform outlet temperature.

[0046] Figure 2 This is a flowchart of a vehicle air conditioning control method provided in an embodiment of the present invention. This embodiment and the vehicle air conditioning system described in the previous embodiment share the same inventive concept. This method can be executed by a vehicle air conditioning control device, which can be implemented using software and / or hardware and integrated into a computer device with application development capabilities.

[0049] The air conditioning set temperature may be a temperature value input by the vehicle occupants via voice, air conditioning control panel, or remote control, etc., as the target temperature value for air conditioning temperature adjustment.

[0050] S120. Determine the water valve opening, the fan gear position, and the compressor operating state according to the air conditioner set temperature value, the sensing value, the vehicle interior temperature, the vehicle exterior temperature, the outlet high temperature zone temperature, and the outlet low temperature zone temperature, so that the temperature difference between the outlet high temperature zone temperature and the outlet low temperature zone temperature is within a preset temperature difference range.

[0051] Specifically, the air-conditioning air outlet control device may determine the working mode of the mode motor according to the temperature inside the vehicle to determine the blowing mode of the vehicle air-conditioning system; determine the working gear of the fan in the blowing mode according to the air-conditioning set temperature value; determine the open or closed state of the water valve according to the temperature difference between the air-conditioning set temperature and the outside temperature, the sensing value, and the temperature of the high-temperature zone and the low-temperature zone of the air outlet; determine the open or closed state of the compressor according to the working gear and the air-conditioning temperature setting value.

[0052] Among them, when determining the open or closed state of the water valve, a table lookup method can be used, wherein the table object to be looked up is a preset water valve opening and closing temperature table. The preset water valve opening and closing temperature table (reference Table 1) can be queried based on the temperature difference between the air conditioner set temperature and the outside temperature of the vehicle, and the sensing value to determine the reference outlet temperature corresponding to opening or closing the water valve; based on the numerical relationship between the outlet high temperature zone temperature and the outlet low temperature zone temperature and the reference outlet temperature, the open or closed state of the water valve is determined. The numerical relationship between the outlet high temperature zone temperature and the outlet low temperature zone temperature and the reference outlet temperature can include the following situations: the reference outlet temperature is the outlet high temperature zone temperature or the outlet low temperature zone temperature; the reference outlet temperature is the average of the outlet high temperature zone temperature and the outlet low temperature zone temperature.

[0053] The fan gear can be determined within a preset low wind gear range, or can be adjusted by the fan control signal duty cycle. The preset temperature difference range can be 0-5 degrees Celsius.

[0054] The technical solution of this embodiment obtains the air conditioner set temperature value, the sensing value of the sunlight sensor, and the vehicle interior temperature, vehicle exterior temperature, outlet high temperature zone temperature, and outlet low temperature zone temperature collected by temperature sensors set at different locations; and determines the water valve opening, fan gear position, and compressor operating state based on the air conditioner set temperature value, the sensing value, vehicle interior temperature, vehicle exterior temperature, outlet high temperature zone temperature, and outlet low temperature zone temperature, so that the temperature difference between the outlet high temperature zone temperature and the outlet low temperature zone temperature falls within a preset temperature difference range. The technical solution of this embodiment of the present invention solves the problem of uneven air conditioner outlet temperature. With the addition of a deflector, the air conditioner operating mode and air volume can be adjusted according to the set temperature value to achieve uniform outlet temperature.
