[0003] The air outlet in the middle of the instrument desk has an independent switch, which can be opened or closed according to actual needs to provide temperature adjustment in a certain direction. However, the air outlet in the middle of the instrument desk is far away from the bed in the sleeper area and can only provide temperature adjustment in a certain direction, and cannot provide air circulation for the passengers in the sleeper area. The temperature difference around the passengers' bodies is large, which affects the comfort of rest.

[0004] The air outlet in the whole area is controlled by a total switch. When the switch is opened, the air outlets towards the driver, the co-pilot and the sleeper area are opened at the same time. When the switch is closed, the air outlets towards the driver, the co-pilot and the sleeper area are closed at the same time. The air outlet in the whole area consumes a large amount of energy, which is not conducive to energy saving and environmental protection.

[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0037] Referring to Figure 1 As shown in the figure, the embodiment of the present application provides a method for controlling air circulation in a sleeping area of a commercial vehicle, and the specific steps include:

[0038] S1: obtaining a signal of a pressure sensor arranged on a bed in a sleeping area of a cab, and a signal of a light sensor arranged on a curtain in the sleeping area of the cab;

[0039] S2: determining a use state of the bed based on the obtained signal of the pressure sensor, and determining a use state of the curtain based on the obtained signal of the light sensor;

[0040] S3: according to the determined use state of the bed in the sleeping area, if the bed in the sleeping area is in an occupied state, proceeding to S4, and if the bed in the sleeping area is in an unused state, proceeding to S5;

[0041] S4: adjusting a working mode of an air outlet arranged at a rear wall of the sleeping area, and a working mode of an air outlet arranged at a middle position of an instrument panel, according to the use state of the curtain;

[0042] S5: adjusting the working mode of the air outlet arranged at the rear wall of the sleeping area.

[0043] That is, the method first obtains a signal of a pressure sensor arranged on a bed in a sleeping area of a cab, and a signal of a light sensor arranged on a curtain in the sleeping area of the cab through an ECU (Electronic Control Unit), wherein the sleeping area of the cab is arranged at a rear of a seat in the cab.

[0044] Then the ECU judges the current use state of the bed in the sleeper area based on the signal of the pressure sensor installed on the bed in the sleeper area, and judges the current use state of the curtain in the sleeper area based on the signal of the light sensor installed on the curtain in the sleeper area. The use state of the bed in the sleeper area is divided into two states, i.e. a use state and a non-use state. When the bed in the sleeper area is in the use state, it means that someone is using the bed in the sleeper area at this time. When the bed in the sleeper area is in the non-use state, it means that no one is using the bed in the sleeper area at this time.

[0045] The ECU adjusts the working mode of the air outlet according to the use state of the bed in the sleeper area. When the bed in the sleeper area is in the use state, it means that someone is using the bed in the sleeper area at this time, and the ECU adjusts the working mode of the air outlet arranged at the rear wall of the sleeper area and the working mode of the air outlet arranged at the middle of the instrument panel according to the use state of the curtain in the sleeper area. When the bed in the sleeper area is in the non-use state, it means that no one is using the bed in the sleeper area at this time, and the ECU only adjusts the working mode of the air outlet arranged at the rear wall of the sleeper area.

[0046] In the application, the use state of the bed is judged based on the signal of the pressure sensor, and specifically:

[0047] When the pressure detected by the pressure sensor is greater than the preset pressure, it is determined that the bed is in the use state.

[0048] When the pressure detected by the pressure sensor is not greater than the preset pressure, it is determined that the bed is in the non-use state.

[0049] That is, the ECU judges the use state of the bed through the signal of the pressure sensor arranged on the bed in the sleeper area. When an external force acts on the pressure sensor arranged on the bed in the sleeper area, the signal of the pressure sensor will change with the action of the external force. When the ECU detects that the pressure detected by the pressure sensor is greater than the preset pressure, it is determined that the bed in the sleeper area is in the use state, i.e. someone is using the bed at this time. The preset pressure is the minimum pressure that the bed in the sleeper area receives when it is normally used.

[0050] When the ECU detects that the pressure detected by the pressure sensor arranged on the bed in the sleeper area is less than or equal to the preset pressure, it is determined that the bed in the sleeper area is not in the use state, i.e. no one is using the bed at this time.

[0051] In the application, the use state of the curtain is judged based on the signal of the light sensor, and specifically:

[0052] When the light intensity detected by the light sensor is greater than the preset light intensity, it is determined that the curtain is in the non-use state.

[0053] When the light intensity detected by the light sensor is not greater than the preset light intensity, it is determined that the curtain is in use.

[0054] That is, the ECU determines the use state of the curtain according to the signal of the light sensor arranged at the side of the curtain of the sleeper area. When the ECU detects that the light intensity detected by the light sensor on the curtain of the sleeper area is greater than the preset light intensity, it is determined that the curtain is not in use, and at this time, the curtain of the sleeper area is in the state of being pulled open, and the light from the outside can irradiate the light sensor at the side of the curtain. The preset light intensity is the minimum light intensity received by the curtain in the state of being pulled open.

[0055] When the ECU detects that the light intensity detected by the light sensor on the curtain of the sleeper area is less than or equal to the preset light intensity, it is determined that the curtain of the sleeper area is in use, and at this time, the curtain of the sleeper area is in the state of being tightly closed. When the sleeper area is in an emergency state, the light sensor arranged at the side of the curtain of the sleeper area is blocked, and at this time, the light sensor cannot receive the light from the outside or receives weak light.

[0056] In the present application, if the bed of the sleeper area is in use, the working mode of the air outlet arranged at the back wall of the sleeper area and the working mode of the air outlet arranged at the middle of the instrument desk are adjusted according to the use state of the curtain, and the specific steps include:

[0057] S301: When the bed of the sleeper area is in use, it is determined that the curtain is in which use state. When the curtain is in use, it is turned to S302, and if the curtain is not in use, it is turned to S303;

[0058] S302: The working mode of the air outlet arranged at the middle of the instrument desk is adjusted to the stop air outlet mode, and the working mode of the air outlet arranged at the back wall of the sleeper area is adjusted to the circular air mode;

[0059] S303: The working mode of the air outlet arranged at the middle of the instrument desk is adjusted to the ventilation mode, and the working mode of the air outlet arranged at the back wall of the sleeper area is adjusted to the slight air mode;

[0060] When the ECU determines that the bed of the sleeper area is in use, the use state of the curtain of the sleeper area is further determined, and according to the use state of the curtain of the sleeper area, the working mode of the air outlet arranged at the back wall of the sleeper area in the cab is adjusted, and the working mode of the air outlet arranged at the middle of the instrument desk in the cab is adjusted.

[0061] When the ECU determines that the bed in the sleeper area is in use, the use state of the window curtain in the sleeper area is determined again, when the ECU determines that the window curtain in the sleeper area is in use, the working mode of the air outlet arranged in the middle of the instrument desk is adjusted to the stop air outlet mode, and the working mode of the air outlet arranged in the rear wall of the sleeper area is adjusted to the ring air mode, when the ECU determines that the window curtain in the sleeper area is not in use, the working mode of the air outlet arranged in the middle of the instrument desk is adjusted to the ventilation mode, and the working mode of the air outlet arranged in the rear wall of the sleeper area is adjusted to the slight air mode.

[0062] When the bed in the sleeper area is in use, that is, the bed in the sleeper area is in use, the use state of the window curtain is further determined, when the window curtain is in use, the state of the window curtain is closed, the sleeper area is independent, the cold and warm air of the air outlet in the instrument desk is blocked by the window curtain in the sleeper area and cannot blow to the bed, at this time, the ECU adjusts the working mode of the air outlet in the instrument desk to the stop air outlet mode, that is, the air outlet in the instrument desk is closed to stop air outlet, and the ECU adjusts the working mode of the air outlet arranged in the rear wall of the sleeper area to the ring air mode, that is, the ECU adjusts the air outlet in the rear wall of the sleeper area to the medium air speed scheme, and forms a ring air effect in the closed sleeper area through the boundary guidance of the top of the sleeper area and the window curtain, so as to ensure that the ambient temperature around the body of the person on the bed in the sleeper area is balanced, and a comfortable resting environment is provided.

[0063] When the bed is in use and the window curtain is not in use, that is, the bed in the sleeper area is in use and the window curtain is not in use, at this time, the window curtain in the sleeper area is opened, the ECU adjusts the working mode of the air outlet in the instrument desk to the ventilation mode, the cold and warm air of the air outlet in the instrument desk can blow to the bed in the sleeper area, and has a certain temperature control effect on the sleeper area, but since the air outlet in the instrument desk can only provide temperature adjustment in one direction, the body of the person on the bed in the sleeper area has a large temperature difference around the body, which affects the comfort of rest. At this time, the ECU adjusts the working mode of the air outlet in the rear wall of the sleeper area to the slight air mode, that is, the air outlet in the rear wall of the sleeper area adopts a low air speed scheme, so as to ensure that the ambient temperature around the body of the person on the bed in the sleeper area is balanced, and a comfortable resting environment is provided.

[0064] In the present application, if the bed in the sleeper area is not in use, the working mode of the air outlet arranged in the rear wall of the sleeper area is adjusted, specifically:

[0065] When the bed in the sleeper area is not in use, the working mode of the air outlet in the rear wall of the sleeper area is adjusted to the stop air outlet mode.

[0066] When the ECU determines that the sleeper berths are unused, it adjusts the operating mode of the air vents located at the rear of the sleeper area to a stop-airflow mode. This means that when the ECU determines that no one is using the sleeper berths, it shuts off the airflow from the rear vents, thus saving energy, reducing emissions, and preventing waste.

[0067] In one possible implementation, the present invention also provides a readable storage medium located in a PLC (Programmable Logic Controller) controller. The readable storage medium stores a computer program that, when executed by a processor, implements the steps of the following commercial vehicle sleeper compartment ventilation control method:

[0068] Acquire signals from pressure sensors located on the berths in the cab sleeper area, and signals from light sensors located on the curtains in the cab sleeper area.

[0069] The bed's usage status is determined based on the acquired pressure sensor signal, and the curtain's usage status is determined based on the acquired light sensor signal;

[0070] Based on the determined usage status of the sleeping area beds, if the sleeping area beds are in use, the working mode of the air vents at the rear of the sleeping area and the air vents in the middle of the dashboard will be adjusted according to the usage status of the curtains; if the sleeping area beds are not in use, the working mode of the air vents at the rear of the sleeping area will be adjusted.

[0071] In this invention, the determination of the bed's usage status based on the acquired pressure sensor signal specifically includes:

[0072] When the pressure detected by the pressure sensor is greater than the preset pressure, the bed is determined to be in use.

[0073] When the pressure detected by the pressure sensor is not greater than the preset pressure, the bed is determined to be in an unused state.

[0074] In this invention, the determination of the curtain's usage status based on the acquired light sensor signal specifically involves:

[0075] When the light intensity detected by the light sensor is greater than the preset light intensity, the curtain is determined to be in an unused state.

[0076] When the light intensity detected by the light sensor is not greater than the preset light intensity, the curtain is determined to be in use.

The computer-readable media can be a computer-readable signal medium or a computer-readable storage medium. The computer-readable storage medium can be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing.

In the context of this document, a computer-readable storage medium can be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device.

[0078] A computer-readable signal medium can include a propagated data signal with computer-readable program code embodied therein, for example, in baseband or as part of a carrier wave. Such a propagated signal can take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination thereof. A computer-readable signal medium can be any computer-readable medium that is not a computer-readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device.

[0079] Computer program code for carrying out operations of the present application can be written in any combination of one or more programming languages, including an object oriented programming language such as Java, Smalltalk, C++ or the like, and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code can execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer, or entirely on the remote computer or server.
