In the present embodiment, the control circuit 130 receives the control instruction and controls the working states of the air conditioner 110 and the air sweeping component 120 according to the control instruction, so as to realize the functions of turning on/off the air conditioner 110, switching the air outlet mode of the air conditioner 110, turning on/off the air sweeping function, and the like. The control instruction may be determined according to the input of the user through a man-machine interaction device on the vehicle, or may be an instruction sent by a server, a mobile terminal or other devices received through a network, or may be an instruction obtained through other modes.

The control circuit 130, upon receiving the sweep start command, acquires the first on-off state of the air conditioner 110 and acquires the current opening of the blown air duct 220a, 220 b. When the first switch state indicates that the air conditioner 110 is in the off state, the control circuit 130 controls the air conditioner 110 to be turned on. When the first switch state indicates that the air conditioner 110 is in the on state and the current opening of the blowing face air channels 220a and 220b is not equal to the blowing face opening, the control circuit 130 controls the air channel adjusting assembly 112 to adjust the opening of the blowing face air channels 220a and 220b to the blowing face opening so that air flow can be blown out from the blowing face air outlet. And when the first switch state indicates that the air conditioner 110 is in the on state and the current opening degree of the blowing side air channels 220a, 220b is equal to the blowing side opening degree, the control circuit 130 keeps the opening degree of the blowing side air channels 220a, 220b at the blowing side opening degree.

In some embodiments, the wind-up command may be divided into a main-drive wind-up command and a co-drive wind-up command. When the control circuit 130 receives a main driving wind sweeping start instruction, the first wind sweeping component is controlled to execute wind sweeping action; when the control circuit 130 receives a copilot wind sweeping start instruction, the second wind sweeping component is controlled to execute wind sweeping action; when the control circuit 130 receives the main driving wind sweeping start command and the auxiliary driving wind sweeping start command, the first wind sweeping component and the second wind sweeping component are controlled to execute wind sweeping action.

In some embodiments, in the wind sweeping mode, when the control circuit 130 receives the air conditioner turning off information, the wind sweeping mode is exited, and the swing blade driving devices 242a and 242b are controlled to stop driving the swing blades 241a and 241b to swing reciprocally. Wherein the air conditioner shut-off information characterizes the air conditioner 110 as being shut off, for example, the air conditioner shut-off information characterizes the air volume of the main air duct 280 as zero. When the air conditioner 110 is turned off in the wind sweeping state, it can be considered that the user has no wind sweeping requirement, and at this time, the control circuit 130 automatically controls the wind sweeping component 120 to stop sweeping wind, so that the wind sweeping component 120 can be prevented from executing an ineffective action in the air conditioner off state, and thus the power supply of the vehicle is saved.

In the wind sweeping mode, when the control circuit 130 receives the wind outlet mode selection instruction, the wind outlet mode corresponding to the wind outlet mode selection instruction is entered. In some embodiments, the air-out mode selection instructions may include defrost mode on instructions, foot-blowing defrost mode on instructions, face-blowing foot-blowing mode on instructions, and other instructions related to the air-out mode of the vehicle air conditioning system 100. The control circuit 130 determines the target opening degrees of the blown-surface air ducts 220a, 220b corresponding to the air-out mode according to the air-out mode selection instruction. When the target opening is zero, it can be considered that there is no wind sweeping demand, the control circuit 130 exits the wind sweeping mode, and controls the swing blade driving devices 242a and 242b to stop driving the swing blades 241a and 241b to swing reciprocally. Thus, the opening degree adjustment of the blowing face air channels 220a and 220b can be associated with the action of the air sweeping assembly 120, the ineffective action of the air sweeping assembly 120 can be reduced, and the intelligent level of the control of the vehicle air conditioning system 100 can be improved.

In the wind sweeping mode, when the control circuit 130 receives the defrosting mode on command, the foot blowing mode on command, or the foot blowing defrosting mode on command, it can be considered that there is no wind sweeping demand. At this time, the control circuit 130 exits the wind sweeping mode, and controls the swing blade driving devices 242a and 242b to stop driving the swing blades 241a and 241b to swing reciprocally. At the same time, the control circuit 130 enters a mode corresponding to the instruction according to the instruction, and controls the air duct adjusting assembly 112 to adjust the opening of the blowing face air ducts 220a, 220b and other relevant air ducts. Thus, the switching of the air outlet mode and the action of the air sweeping component 120 can be associated, the ineffective action of the air sweeping component 120 can be reduced, and the intelligent level of the control of the vehicle air conditioning system 100 is improved.

Embodiments of the present invention are also directed to a vehicle including the vehicle air conditioning system 100 of at least some embodiments of the present invention. The electric power system of the vehicle is electrically connected with the vehicle air conditioning system 100 to supply electric power to the vehicle air conditioning system 100. An Electronic Control Unit (ECU) of the vehicle is electrically connected to the control circuit 130 of the vehicle air conditioning system 100 to enable signal transmission, or the control circuit 130 of the vehicle air conditioning system 100 may be partially or fully integrated in the electronic control unit of the vehicle. By adopting the vehicle air conditioning system 100 in at least some embodiments of the present invention, the association of the operation of the wind sweeping component 120 and the air conditioner 110 can be achieved, the intelligent level of the control of the air conditioner 110 can be improved, and the convenience of the operation of the vehicle air conditioner 110 by the driver and/or the passenger can be improved.

The embodiment of the invention also relates to a control method of the vehicle air conditioning system. In some application scenarios, the method may be performed by the control circuit 130 of the vehicle air conditioning system 100 described hereinabove with reference to fig. 1 and 2 to control the vehicle air conditioning system 100.

Fig. 3 is a schematic flow chart of opening a wind sweeping according to an embodiment of the invention. As shown in fig. 3, in some embodiments, the control method of the vehicle air conditioning system includes steps S310 to S340 as follows:

step S310, responding to the received wind sweeping opening instruction, entering a wind sweeping mode, acquiring a first switch state of the air conditioner, and acquiring the current opening of the blowing face air duct.

The control circuit 130, upon receiving the sweep start command, acquires the first on-off state of the air conditioner 110 and acquires the current opening of the blown air duct 220a, 220 b. The first switch state is a switch state of the air conditioner 110 when the control circuit 130 receives the wind sweeping start command. The first switch state may be determined by detecting a power-on state of the blower 111, an air volume in the main air duct 280, or other means. The first switch state of the air conditioner 110 and the current opening of the blowing side air ducts 220a and 220b may be acquired simultaneously or sequentially. Upon receiving the wind-sweeping start instruction, the control circuit 130 enters a wind-sweeping mode.

Step S320, when the first switch state indicates that the air conditioner is in the closed state, controlling the air conditioner to be turned on.

When the first switch state indicates that the air conditioner 110 is in the off state, the control circuit 130 controls the air conditioner 110 to be turned on. In this embodiment, when the air conditioner 110 is turned on, the blower 111, the air duct adjusting assembly 112 and other related devices of the air conditioner 110 are powered on, and the blower 111 enters an operating state to generate an air flow.

And step S330, when the first switch state represents that the air conditioner is in an on state and the current opening of the blowing face air duct is not equal to the blowing face opening, controlling an air duct adjusting assembly to adjust the opening of the blowing face air duct to be the blowing face opening.

When the first switch state indicates that the air conditioner 110 is in the on state and the current opening of the blowing face air channels 220a and 220b is not equal to the blowing face opening, the control circuit 130 controls the air channel adjusting assembly 112 to adjust the opening of the blowing face air channels 220a and 220b to the blowing face opening so that air flow can be blown out from the blowing face air outlet. The blowing opening is greater than zero, and a specific value of the blowing opening can be predetermined according to the needs of the actual application scene or determined according to the input of a user.

And S340, controlling the swing blade driving device to drive the swing blade to swing in a reciprocating manner in the wind sweeping mode.

In the wind sweeping mode, the control circuit 130 controls the swing blade driving devices 242a and 242b to drive the swing blades 241a and/or 241b to swing reciprocally according to a predetermined period, so as to periodically adjust the airflow direction of the blowing face air outlet, thereby realizing wind sweeping.

In some embodiments, the wind sweep mode includes a primary drive wind sweep mode and a secondary drive wind sweep mode, and the wind sweep on command may be divided into a primary drive wind sweep on command and a secondary drive wind sweep on command. According to the difference of the wind-sweeping start command received in step S310, step S340 may include the following two cases: in the main driving wind sweeping mode, the swing blade driving device 242a is controlled to drive the swing blade 241a of the main driving blowing surface air outlet to swing in a reciprocating manner; in the co-pilot wind sweeping mode, the swing blade driving device 242b is controlled to drive the swing blade 241b of the co-pilot blowing face air outlet to swing in a reciprocating manner. Thereby, the fine control of wind sweeping at different positions in the vehicle can be realized.

The execution sequence of the above steps S310 to S340 is not limited to the steps shown in fig. 3, and the specific execution sequence may be adjusted as needed. For example, the control circuit 130 may control the swing blade driving device 242a and/or 242b to drive the swing blade 241a and/or 241b to swing reciprocally (step S340) simultaneously with obtaining the first switch state of the air conditioner 110 and the current opening of the blowing face air duct 220a, 220b (step S310); alternatively, when the air conditioner 110 is in the on state and the current opening of the blowing air channels 220a and 220b is equal to the blowing opening, the control circuit 130 controls the air sweeping component 120 to perform the air sweeping action, so that the swing blade driving device 242a and/or 242b drives the swing blade 241a and/or 241b to swing reciprocally, that is, step S310 and step S330 may be performed first and then step S340 may be performed.

Fig. 4 is a flowchart illustrating a control procedure in a scenario in which the air conditioner 110 is turned off in the wind sweeping mode, according to an embodiment of the present invention. As shown in fig. 4, in some embodiments, the control method of the vehicle air conditioning system includes steps S410 to S420, wherein step S410 corresponds to step S340 in fig. 3.

Step S410, under the wind sweeping mode, the swing blade driving device is controlled to drive the swing blade to swing in a reciprocating mode.

And step S420, in the wind sweeping mode, responding to the receiving of the closing information of the air conditioner, exiting the wind sweeping mode, and controlling the swing blade driving device to stop driving the swing blade to swing in a reciprocating manner.

When the control circuit 130 controls the wind sweeping component 120 to perform wind sweeping according to the wind sweeping opening instruction, if the air conditioner closing information is received, the user can be considered to have no wind sweeping requirement, and at this time, the control circuit 130 automatically controls the swing blade driving devices 242a and 242b to stop driving the swing blades 241a and 241b to swing reciprocally, and the wind sweeping action is stopped. The air conditioner turn-off information may be obtained by periodically detecting the state of the air conditioner 110 by the control circuit 130, or may be determined according to an air conditioner turn-off instruction input by a user.

Fig. 5 is a schematic flow chart of another embodiment of the present invention, which illustrates a control flow in a scenario of switching an air outlet mode during a wind sweeping mode. As shown in fig. 5, in some embodiments, the control method of the vehicle air conditioning system includes steps S510 to S520, wherein step S510 corresponds to step S340 in fig. 3.

And S510, controlling the swing blade driving device to drive the swing blade to swing in a reciprocating manner in the wind sweeping mode.

And step S520, under the wind sweeping mode, responding to receiving a defrosting mode starting instruction, a foot blowing mode starting instruction or a foot blowing defrosting mode starting instruction, exiting the wind sweeping mode, and controlling the swing blade driving device to stop driving the swing blade to swing reciprocally.

In the wind sweeping mode, when the control circuit 130 receives the defrosting mode on command, the foot blowing mode on command, or the foot blowing defrosting mode on command, it can be considered that there is no wind sweeping demand. At this time, the control circuit 130 exits the wind sweeping mode and controls the swing blade driving devices 242a and 242b to stop driving the swing blades 241a and 241b to swing reciprocally. Meanwhile, the control circuit 130 may also enter a mode corresponding to the defrosting mode on command, the foot blowing mode on command, or the foot blowing defrosting mode on command according to the command.

Fig. 6 is a schematic flow chart of switching from the wind sweeping mode to the other wind outlet modes according to one embodiment of the invention, which shows a control flow in a scenario of switching the wind outlet modes in the wind sweeping mode. As shown in fig. 6, in some embodiments, the control method of the vehicle air conditioning system includes steps S610 to S630, wherein step S610 corresponds to step S340 in fig. 3.

Step S610, under the wind sweeping mode, the swing blade driving device is controlled to drive the swing blade to swing in a reciprocating mode.

Step S620, in the wind sweeping mode, in response to receiving the wind outlet mode selection instruction, entering a wind outlet mode corresponding to the wind outlet mode selection instruction, and determining a target opening of the blowing face wind channel corresponding to the wind outlet mode.

In some embodiments, the air out mode may include a defrost mode, a foot-blow defrost mode, a face-blow foot-blow mode; the air-out mode selection instructions may include defrost mode on instructions, foot-blowing defrost mode on instructions, face-blowing foot-blowing mode on instructions, and other instructions related to the air-out mode of the vehicle air conditioning system 100. Each air outlet mode has a predetermined opening degree of the corresponding air-blowing surface air duct 220a, 220b, and the control circuit 130 determines a target opening degree of the air-blowing surface air duct 220a, 220b corresponding to the air outlet mode according to the air outlet mode selection instruction.

And step 630, when the target opening degree is zero, exiting the wind sweeping mode, and controlling the swing blade driving device to stop driving the swing blade to swing in a reciprocating manner.

When the target opening is zero, it can be considered that there is no wind sweeping demand, the control circuit 130 exits the wind sweeping mode, and controls the swing blade driving devices 242a and 242b to stop driving the swing blades 241a and 241b to swing reciprocally. For example, in the defrost mode, the foot-blow mode, or the foot-blow defrost mode, the target opening degree is zero, and the control circuit 130 exits the wind-sweeping mode.
