Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a vehicle air conditioner and a control method, device, electronic equipment and readable medium thereof. Background Art

[0002] The double-flow HVAC system has three modes: internal circulation, external circulation and mixed air mode. HVAC is a comprehensive system of heating, ventilation and air conditioning.

[0003] In the internal circulation mode, the dual-layer air conditioning HVAC system can recycle air from the vehicle and blow it back into the vehicle after heating. In the external circulation mode, the dual-layer air conditioning HVAC system can introduce fresh cold air from the outside into the vehicle, and then blow it back into the vehicle after heating it through the vehicle's internal heater. Since the vehicle's internal heater requires more energy to heat the cold air entering the vehicle to increase the temperature inside the vehicle, this increases the workload and energy consumption of the vehicle's internal heater, shortening the range of new energy vehicles.

[0004] In the mixed air mode, the double-flow HVAC system can adjust between internal and external circulation. This mode can not only introduce fresh air from the outside, but also reduce the workload of the heater. However, in order to achieve this mixed air function, a special flow channel baffle is designed in the double-flow HVAC system, and the blower is equipped with a diversion structure, which increases the production cost of the double-flow HVAC system and makes the manufacturing process more complicated.

[0005] In addition, when the dual-flow air conditioning HVAC system performs external circulation in mixed air mode, it will inhale outside air to balance the air pressure inside the vehicle with the air pressure at the air intake of the external circulation. During vehicle driving, as the vehicle speed increases, the air flow rate at the air intake of the external circulation increases, causing the static air pressure there to decrease and forming a higher dynamic pressure. Therefore, the air pressure at the air intake of the external circulation is relatively high, which in turn increases the pressure and flow of the air intake of the external circulation. When the vehicle speed increases, the amount of air passing through the air intake of the external circulation increases compared to when the vehicle is stationary, which may affect the dual-flow air conditioning HVAC system's control of the ratio of the internal and external circulation air intake in mixed air mode. Summary of the invention

[0059] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0060] To facilitate understanding of the technical solutions and technical effects of the embodiments of the present invention, the prior art of the present invention is briefly described below.

[0061] When using new energy vehicles in winter, if the user turns on the full external circulation mode of the air conditioner (i.e. 100% external circulation), the low-temperature cold air outside the car will directly enter the car. Since the vehicle's internal heater requires more energy to heat the cold air entering the car to increase the temperature inside the car, this increases the workload and energy consumption of the vehicle's heater. Under this high-load working state, the vehicle will consume more electricity, resulting in a shorter cruising range of new energy vehicles.

[0062] To solve this problem, the automotive industry has developed many HVAC systems with mixed air structures, such as double-flow air conditioning HVAC systems.

[0063] Reference Figure 1 , showing a schematic diagram of a double-flow air conditioning HVAC system in the prior art. Figure 1 The TwoLayerFlow HVAC in it refers to the two-layer flow air-conditioning HVAC system; Rec.Air refers to the internal air or recirculated air, that is, the air in the car, which can be used for the internal circulation of the two-layer flow air-conditioning HVAC system; OutletAir refers to the external air, that is, the external fresh air, which can be used for the external circulation of the two-layer flow air-conditioning HVAC system; DEF refers to the defrost function of the two-layer flow air-conditioning HVAC system, which can be used to remove frost or fog on the front windshield of the vehicle; FACE refers to the face-blowing function of the two-layer flow air-conditioning HVAC system, which can be used to direct warm air or cold air to the face area of ​​the driver and passengers; FOOT refers to the foot-blowing function of the two-layer flow air-conditioning HVAC system, which can be used to direct warm air to the foot area of ​​the driver and passengers; Rr.FOOT refers to the rear foot-blowing function of the two-layer flow air-conditioning HVAC system, which can be used to provide warm air to the foot area of ​​​​the passengers in the back seats of the vehicle.

[0064] Figure 1The lines drawn by Rec.Air show the specific path of air flow when the double-flow air-conditioning HVAC system performs internal circulation; the lines drawn by OutletAir show the specific path of air flow when the double-flow air-conditioning HVAC system performs external circulation.

[0065] The dual-layer air conditioning HVAC system also has a mixed air mode that can adjust between internal and external circulation. This mode can not only introduce fresh air from the outside, but also reduce the workload of the heater, thereby ensuring the comfort of the car while reducing power consumption, thereby improving the endurance of new energy vehicles.

[0066] However, in order to achieve this air mixing function, a special flow channel baffle is designed in the double-flow air conditioning HVAC system, and the blower is equipped with a diversion structure to prevent the external fresh air entering the air conditioner from the external circulation air intake of the double-flow air conditioning HVAC system from directly entering the vehicle through the internal circulation air intake. These designs increase the production cost of the double-flow air conditioning HVAC system and make the manufacturing process more complicated.

[0067] In addition, when the dual-flow air conditioning HVAC system performs external circulation in mixed air mode, it will inhale outside air to balance the air pressure inside the vehicle with the air pressure at the air intake of the external circulation. During vehicle driving, as the vehicle speed increases, the air flow rate at the air intake of the external circulation increases, causing the static air pressure there to decrease and forming a higher dynamic pressure. Therefore, the air pressure at the air intake of the external circulation is relatively high, which in turn increases the pressure and flow of the air intake of the external circulation. When the vehicle speed increases, the amount of air passing through the air intake of the external circulation increases compared to when the vehicle is stationary, which may affect the dual-flow air conditioning HVAC system's control of the ratio of the internal and external circulation air intake in mixed air mode.

[0068] Reference Figure 2 , showing a schematic diagram of a vehicle air conditioner provided in an embodiment of the present invention, the vehicle air conditioner at least comprises an inner circulation damper 2, an outer circulation damper 1 and a compensation damper, wherein the inner circulation damper 2 has an on / off function, and the outer circulation damper 1 can adjust the opening degree;

[0069] The compensation damper is used to introduce the first internal air of the vehicle into the air conditioner; the external circulation damper is used to introduce the external air of the vehicle into the air conditioner;

[0070] The air conditioner has at least a mixed air mode; when the vehicle is in a preset driving state and the air conditioner is in the mixed air mode, the external circulation damper and the compensation damper are in an open state, the internal circulation damper is in a closed state, the first internal gas is used for internal circulation of the air conditioner, and the external gas is used for external circulation of the air conditioner, and the target opening degree of the external circulation damper is determined based on the driving speed of the vehicle and a preset ratio requirement between the intake volume of the internal circulation and the intake volume of the external circulation.

[0071] In an embodiment of the present invention, the vehicle air conditioner is an HVAC system with a mixed air structure. Figure 2 The air conditioner includes an internal circulation damper, an external circulation damper, a compensating damper and a blower. Among them, the external circulation damper can adjust the opening degree, and the internal circulation damper has two states: open and closed. The internal circulation damper can also be called the internal circulation air inlet; the external circulation damper can also be called the external circulation air inlet.

[0072] The blower can generate airflow, adjust the air flow direction inside the vehicle, guide the airflow inside the vehicle through the compensation damper and / or the internal circulation damper into the air conditioner, and realize the internal circulation of the air conditioner. At the same time, the blower can also generate airflow, adjust the air flow direction outside the vehicle, guide the airflow outside the vehicle into the air conditioner through the external circulation damper, and realize the external circulation of the air conditioner. The internal air of the vehicle entering the air conditioner through the compensation damper is the first internal gas of the vehicle, or the compensation airflow. The internal air of the vehicle entering the air conditioner through the internal circulation damper is the second internal gas of the vehicle. The external air of the vehicle entering the air conditioner through the external circulation damper can be called the external circulation airflow. Therefore, the compensation damper can introduce the first internal gas of the vehicle into the air conditioner, the internal circulation damper can introduce the second internal gas of the vehicle into the air conditioner, and the external circulation damper can introduce the external gas of the vehicle into the air conditioner.

[0073] It should be noted that the compensation damper is located at the upper part of the air conditioner, and the external circulation damper is located at the lower part of the air conditioner. When the compensation damper is located at the upper part of the air conditioner, the blower can adjust the flow direction of the air inside the vehicle so that the first internal air of the vehicle enters the interior of the air conditioner through the compensation damper.

[0074] In the embodiment of the present invention, the air conditioner has at least a mixed air mode. When the air conditioner is in the mixed air mode, the air conditioner can adjust between the internal and external circulations, and adjust the ratio between the air intake of the internal circulation and the air intake of the external circulation, so that the ratio between the air intake of the internal circulation and the air intake of the external circulation meets the preset ratio requirement.

[0075] Reference Figure 3, shows a schematic diagram of a vehicle in a driving state provided in an embodiment of the present invention. During the driving process of the vehicle, as the vehicle speed increases, the air flow rate at the external circulation damper at the front of the vehicle increases, resulting in a decrease in the static air pressure there, forming a higher dynamic pressure. Therefore, the air pressure at the external circulation damper is relatively high, thereby increasing the pressure and flow of the intake air of the external circulation.

[0076] In an embodiment of the present invention, if the air conditioner is in a mixed air mode during driving of a vehicle, the external circulation damper and the compensation damper of the air conditioner are in an open state, and the internal circulation damper of the air conditioner is in a closed state, the first internal gas entering the air conditioner through the compensation damper is used for the internal circulation of the air conditioner, and the external gas entering the air conditioner through the external circulation damper is used for the external circulation of the air conditioner.

[0077] If the air conditioner is in mixed air mode during vehicle driving, the compensating damper is in full open state, and the target opening degree of the external circulation damper is determined based on the vehicle's driving speed and the preset ratio between the internal circulation air intake and the external circulation air intake.

[0078] As the vehicle speed increases, the intake air flow rate of the external circulation increases, so the intake air volume of the external circulation is associated with the vehicle speed. Since the intake air volume of the external circulation is also related to the opening degree of the external circulation damper, the target opening degree of the external circulation damper is determined based on the vehicle speed and the preset ratio requirement between the intake air volume of the internal circulation and the intake air volume of the external circulation, and the intake air flow rate of the external circulation can be adjusted so that the ratio between the intake air volume of the first internal gas entering the air conditioner through the compensation damper and the intake air volume of the external gas entering the air conditioner through the external circulation damper meets the preset ratio requirement, so that the ratio between the intake air volumes of the internal and external circulations of the air conditioner meets the preset ratio requirement.

[0079] In an embodiment of the present invention, the air conditioner of the vehicle at least comprises an inner circulation damper, an outer circulation damper and a compensation damper; the compensation damper is used to introduce the first internal air of the vehicle into the air conditioner; the outer circulation damper is used to introduce the external air of the vehicle into the air conditioner; the air conditioner at least has a mixed air mode; when the vehicle is in a preset driving state and the air conditioner is in the mixed air mode, the outer circulation damper and the compensation damper are in an open state, the inner circulation damper is in a closed state, the first internal air is used for the inner circulation of the air conditioner, and the external air is used for the external circulation of the air conditioner, and the target opening degree of the external circulation damper is determined based on the driving speed of the vehicle and the preset ratio between the intake volume of the inner circulation and the intake volume of the external circulation. The air conditioner realizes the mixed air function by closing the inner circulation damper and opening the outer circulation damper and the compensation damper, thereby preventing the external air entering the air conditioner from the external circulation damper of the air conditioner directly entering the air conditioner in the vehicle through the inner circulation damper; the air conditioner in the embodiment of the present invention does not need to be equipped with a special flow channel partition, and the blower of the air conditioner does not need to be equipped with a diversion structure, which reduces the production cost of the HVAC system of the mixed air structure and makes the manufacturing process simpler.

[0080] In addition, when the vehicle is in a preset driving state and the air conditioner is in mixed air mode, the compensating damper is in a fully open state. The opening degree of the external circulation damper is determined based on the vehicle's driving speed and the preset ratio requirement between the air intake volume of the internal circulation and the air intake volume of the external circulation. The flow rate of the air intake of the external circulation can be adjusted so that the ratio between the air intake volume of the first internal gas entering the air conditioner through the compensating damper and the air intake volume of the external gas entering the air conditioner through the external circulation damper meets the preset ratio requirement, and the ratio between the air intake volumes of the internal and external circulations of the air conditioner meets the preset ratio requirement.

[0081] Further, in any of the above embodiments, the internal circulation damper is used to introduce the second internal air of the vehicle into the air conditioner;

[0082] The air conditioner also has an internal circulation mode and an external circulation mode;

[0083] When the air conditioner is in the external circulation mode, the internal circulation damper is in a closed state, and the compensation damper and the external circulation damper are in an open state;

[0084] When the air conditioner is in the internal circulation mode, the external circulation damper is in a closed state, the compensation damper and the internal circulation damper are in an open state, and the second internal air is used for the internal circulation of the air conditioner.

[0085] In the embodiment of the present invention, the internal circulation damper can introduce the second internal air of the vehicle into the air conditioner. The air conditioner has a mixed air mode, an internal circulation mode and an external circulation mode.

[0086] When the air conditioner is in mixed air mode, internal circulation mode and external circulation mode, the opening status of the external circulation damper, internal circulation damper and compensation damper are shown in the following table:

[0087]

[0088] When the air conditioner is in external circulation mode, the internal circulation damper is in a closed state, the compensation damper and the external circulation damper are in an open state, the first internal gas entering the air conditioner through the compensation damper is used for the internal circulation of the air conditioner, and the external gas entering the air conditioner through the external circulation damper is used for the external circulation of the air conditioner.

[0089] When the air conditioner is in the internal circulation mode, the external circulation damper is in the closed state, the compensation damper and the internal circulation damper are in the open state, the first internal gas entering the air conditioner through the compensation damper is used for the internal circulation of the air conditioner, and the second internal gas entering the air conditioner through the internal circulation damper is used for the internal circulation of the air conditioner.

[0090] If the air conditioner is in mixed air mode during vehicle driving, the air conditioner's external circulation damper and compensation damper are in an open state, and the air conditioner's internal circulation damper is in a closed state, the first internal air entering the air conditioner through the compensation damper is used for the air conditioner's internal circulation, and the external air entering the air conditioner through the external circulation damper is used for the air conditioner's external circulation. The target opening degree of the external circulation damper is determined based on the vehicle's driving speed and a preset ratio requirement between the air intake volume of the internal circulation and the air intake volume of the external circulation.

[0091] In an embodiment of the present invention, when the air conditioner is in the internal circulation mode, the external circulation damper is in a closed state, the compensating damper and the internal circulation damper are in an open state, the first internal gas entering the air conditioner through the compensating damper is used for the internal circulation of the air conditioner, and the second internal gas entering the air conditioner through the internal circulation damper is used for the internal circulation of the air conditioner, thereby improving the efficiency of the internal circulation of the air conditioner; when the air conditioner is in the external circulation mode, the internal circulation damper is in a closed state, the compensating damper and the external circulation damper are in an open state, the first internal gas entering the air conditioner through the compensating damper is used for the internal circulation of the air conditioner, and the external gas entering the air conditioner through the external circulation damper is used for the external circulation of the air conditioner, and when the air conditioner is in the external circulation mode, the first internal gas entering the air conditioner through the compensating damper is used for the internal circulation of the air conditioner, and since the first internal gas entering the air conditioner through the compensating damper is not the cold air outside the vehicle, it does not need to be heated again, thereby saving the vehicle's electric energy.

[0092] Further, in any of the above embodiments, the air conditioner further comprises a blower;

[0093] The blower is used to adjust the flow directions of the first internal air, the second internal air and the external air, so that the first internal air, the second internal air and the external air are introduced into the air conditioner through the compensation damper, the internal circulation damper and the external circulation damper respectively; the opening gear of the blower is associated with the intake amount of the compensation damper, the internal circulation damper and the external circulation damper;

[0094] When the vehicle is in the driving state and the air conditioner is in the mixed air mode, the target opening degree of the external circulation damper is determined based on the driving speed of the vehicle, the opening gear of the blower and the preset ratio requirement between the air intake volume of the internal circulation and the air intake volume of the external circulation.

[0095] In an embodiment of the present invention, the air conditioner further includes a blower. The blower can adjust the flow direction of the first internal air, the second internal air, and the external air of the vehicle, so that the first internal air, the second internal air, and the external air are introduced into the air conditioner through the compensation damper, the internal circulation damper, and the external circulation damper, respectively. The opening gear of the blower is associated with the intake amount of the compensation damper, the internal circulation damper, and the external circulation damper.

[0096] Therefore, when the vehicle is in motion and the air conditioner is in mixed air mode, the target opening degree of the external circulation damper is determined based on the vehicle's driving speed, the opening gear of the blower, and the preset ratio requirement between the air intake volume of the internal circulation and the air intake volume of the external circulation.

[0097] In the embodiment of the present invention, if the required setting value of the intake volume ratio of the external gas of the external circulation damper is X, the opening degree of the external circulation damper is as shown in the following table. It should be noted that if the preset ratio requirement between the intake volume of the internal and external circulation of the air conditioner is 50%:50%, then X=50; if the preset ratio requirement between the intake volume of the internal and external circulation of the air conditioner is 10%:90%, then X=90.

[0098]

[0099]

[0100] If the preset ratio of the air intake volume between the internal and external circulation of the air conditioner is 50%:50%, then X=50. At the same time, if the blower is turned on at gear 5 and the vehicle speed is 100 km / h, the calculation formula for the external circulation damper opening A is:

[0101] A=50*90%-5=40%

[0102] Therefore, if the preset ratio between the air intake volume of the internal and external circulation of the air conditioner is 50%:50%, the blower is turned on at gear 5, and the vehicle speed is 100 km / h, the external circulation damper opening A is 40%.

[0103] In an embodiment of the present invention, when the vehicle is in driving state and the air conditioner is in mixed air mode, the target opening degree of the external circulation damper is determined based on the vehicle's driving speed, the opening gear of the blower, and a preset ratio requirement between the air intake volume of the internal circulation and the air intake volume of the external circulation, thereby ensuring that the ratio between the air intake volume of the first internal gas entering the air conditioner through the compensation damper and the air intake volume of the external gas entering the air conditioner through the external circulation damper meets the preset ratio requirement, so that the ratio between the air intake volumes of the internal and external circulations of the air conditioner meets the preset ratio requirement.

[0104] Reference Figure 4 , shows a flow chart of the steps of a control method for an air conditioner of a vehicle provided in an embodiment of the present invention, wherein the air conditioner of the vehicle at least comprises an inner circulation damper, an outer circulation damper and a compensation damper; the outer circulation damper is used to introduce the external air of the vehicle into the air conditioner; the external air is used to perform the external circulation of the air conditioner; the air conditioner at least has a mixed air mode; specifically, the following steps may be included:

[0105] Step 401, when the vehicle is in a preset driving state and the air conditioner is in the mixed air mode, obtaining the driving speed of the vehicle;

[0106] Step 402, controlling the internal circulation damper to close, and controlling the compensation damper to open, so that the compensation damper introduces the first internal air of the vehicle into the air conditioner; the first internal air is used for internal circulation of the air conditioner;

[0107] Step 403, determining a target opening degree of the external circulation damper based on the driving speed and a preset ratio requirement between the air intake amount of the internal circulation and the air intake amount of the external circulation;

[0108] Step 404, adjusting the opening degree of the external circulation damper to the target opening degree, so that the ratio between the air intake volume of the internal circulation of the air conditioner and the air intake volume of the external circulation meets the preset ratio requirement.

[0109] In an embodiment of the present invention, the air conditioner of the vehicle at least includes an inner circulation damper, an outer circulation damper and a compensation damper, the outer circulation damper is used to introduce the external air of the vehicle into the air conditioner, the external air is used for the external circulation of the air conditioner, and the air conditioner has at least a mixed air mode. When the vehicle is in a preset driving state and the air conditioner is in the mixed air mode, the driving speed of the vehicle is obtained, the inner circulation damper is controlled to be closed, and the compensation damper is controlled to be opened, so that the compensation damper introduces the first internal air of the vehicle into the air conditioner. The first internal air is used for the internal circulation of the air conditioner. Based on the driving speed and the preset ratio requirement between the air intake amount of the inner circulation and the air intake amount of the outer circulation, the target opening degree of the outer circulation damper is determined, and the opening degree of the outer circulation damper is adjusted to the target opening degree, so that the ratio between the air intake amount of the inner circulation of the air conditioner and the air intake amount of the outer circulation meets the preset ratio requirement. The air conditioner realizes the air mixing function by closing the inner circulation damper and opening the outer circulation damper and the compensation damper, thereby preventing the external air entering the air conditioner from the outer circulation damper of the air conditioner and directly entering the air conditioner in the car through the inner circulation damper; the air conditioner in the embodiment of the present invention does not need to be equipped with a special flow channel baffle, and the blower of the air conditioner does not need to be equipped with a diversion structure, which reduces the production cost of the HVAC system with a mixing structure and makes the manufacturing process simpler.

[0110] In addition, when the vehicle is in a preset driving state and the air conditioner is in mixed air mode, the compensating damper is in a fully open state. Based on the vehicle's driving speed and the preset ratio requirement between the air intake volume of the internal circulation and the air intake volume of the external circulation, the target opening degree of the external circulation damper is determined, and the opening degree of the external circulation damper is adjusted to the target opening degree. The air intake flow of the external circulation can be adjusted so that the ratio between the air intake volume of the first internal gas entering the air conditioner through the compensating damper and the air intake volume of the external gas entering the air conditioner through the external circulation damper meets the preset ratio requirement, and the ratio between the air intake volumes of the internal and external circulations of the air conditioner meets the preset ratio requirement.

When the air conditioner is in the internal circulation mode, the external circulation damper is controlled to be closed, the compensation damper is controlled to be opened, and the internal circulation damper is controlled to be opened, so that the internal circulation damper introduces the second internal air of the vehicle into the air conditioner, and the second internal air is used for the internal circulation of the air conditioner. The first internal air entering the air conditioner through the compensation damper is used for the internal circulation of the air conditioner, and the second internal air entering the air conditioner through the internal circulation damper is used for the internal circulation of the air conditioner, thereby improving the efficiency of the internal circulation of the air conditioner.

[0116] Furthermore, in any of the above embodiments, the air conditioner also has an external circulation mode; and the method further includes:

[0117] Sub-step S21, when the air conditioner is in the external circulation mode, controlling the internal circulation damper to close;

[0118] Sub-step S22, controlling the compensation damper and the external circulation damper to open.

[0119] In an embodiment of the present invention, the air conditioner also has an external circulation mode. When the air conditioner is in the external circulation mode, the internal circulation damper is controlled to be closed, and the compensation damper and the external circulation damper are controlled to be opened. When the air conditioner is in the external circulation mode, the first internal air entering the air conditioner through the compensation damper is used for the internal circulation of the air conditioner, and the external air entering the air conditioner through the external circulation damper is used for the external circulation of the air conditioner. Since the first internal air entering the air conditioner through the compensation damper is not the cold air outside the vehicle, it does not need to be heated again, thereby saving the electric energy of the vehicle.

[0120] Further, in any of the above embodiments, the air conditioner further comprises a blower; the blower is used to adjust the flow direction of the first internal air and the external air, so that the first internal air and the external air are introduced into the air conditioner through the compensation damper and the external circulation damper respectively; the opening gear of the blower is associated with the intake amount of the compensation damper and the external circulation damper; step 403 comprises:

[0121] Sub-step S31, determining a target opening degree of the external circulation damper based on the driving speed, the opening gear of the blower, and a preset ratio between the air intake amount of the internal circulation and the air intake amount of the external circulation.

[0122] In an embodiment of the present invention, the air conditioner further includes a blower. The blower can adjust the flow direction of the first internal gas and the external gas, so that the first internal gas and the external gas are introduced into the air conditioner through the compensation damper and the external circulation damper, respectively. The opening gear of the blower is associated with the air intake amount of the compensation damper and the external circulation damper, and the target opening degree of the external circulation damper is determined based on the vehicle's driving speed, the opening gear of the blower, and the preset ratio requirement between the air intake amount of the internal circulation and the air intake amount of the external circulation, ensuring that the ratio between the air intake amount of the first internal gas entering the air conditioner through the compensation damper and the air intake amount of the external gas entering the air conditioner through the external circulation damper meets the preset ratio requirement, so that the ratio between the air intake amounts of the internal and external circulations of the air conditioner meets the preset ratio requirement.
