[0049] The method embodiment provided in this embodiment can be executed in a terminal, a computer or a similar computing device. For example, running on a terminal, Figure 1 FIG. 1 is a hardware structure block diagram of a terminal of the vehicle air conditioning control method of this embodiment. Figure 1 As shown, the terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102 and memory 104 for storing data, wherein processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA.

In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0052] In this embodiment, a method for controlling a vehicle air conditioner is provided. Figure 2 is a flow chart of the vehicle air conditioning control method of this embodiment. Figure 2 As shown, the process includes the following steps:

[0053] Step S210, when it is detected that the sitting state of the occupant in the vehicle changes, an image signal of the occupant in the vehicle, a seat pressure signal in the vehicle, and an infrared signal of the occupant in the vehicle are acquired.

[0054] The above-mentioned change in the sitting state can specifically be the detection of a passenger sitting down or leaving the vehicle seat. Based on the change in the sitting state, the real-time adjustment of the vehicle air conditioner is triggered. Among them, by introducing an intelligent cockpit system for the vehicle, based on the intelligent cockpit system, the driver monitoring system and the occupant monitoring system judge the number and position of occupants in the passenger compartment inside the vehicle based on visual sampling, determine which seat has an occupant, and realize the recognition and monitoring of the body movements and facial expressions of all occupants in the vehicle based on visual sampling. In addition, the seat pressure sensor and the infrared camera can be combined to further obtain the actual occupant information with higher accuracy. Specifically, based on the visual camera equipment, the image signal of the occupants inside the vehicle can be obtained, based on the seat pressure sensor, the seat pressure signal inside the vehicle can be obtained, and based on the infrared camera equipment, the infrared signal of the occupants inside the vehicle can be obtained.

[0055] Step S220, determining the current number of passengers in the vehicle, the seating position and the seating posture of the passengers based on the image signal, the seat pressure signal and the infrared signal.

[0056] In this step, signals from different sources are combined to obtain more accurate and reliable passenger information. For example, the number of passengers and their sitting postures in the current vehicle can be confirmed based on the image signal; the distribution information and number of passengers in different seats in the passenger compartment can be determined based on the seat pressure signal. The number of passengers and the distribution of passengers can also be determined based on infrared cameras. Therefore, the above information can be combined with each other to obtain more accurate passenger numbers, passenger seating positions, and sitting postures.

[0057] In particular, the seat pressure signal can only detect whether the occupant is sitting, but cannot know the occupant's status. For example, based on the seat pressure signal of the front passenger seat, it can only be determined whether the occupant is sitting in the front passenger seat. If the occupant lowers the seat back to lie flat in the front passenger seat, this sitting posture cannot be determined by the seat pressure signal alone. Therefore, in order to obtain more comprehensive and rich occupant information, this step is assisted by visual acquisition signals, which can collect real-time image information, thereby confirming the specific and actual sitting posture of the occupant on the seat, so as to obtain more accurate and specific occupant information.

[0058] Step S230, determining the target air conditioning air volume and target air outlet mode of the vehicle according to the number of passengers, the seating positions and the seating postures of the passengers.

[0059] After obtaining the above-mentioned passenger information, the measurement value can be output. Among them, the measurement value can be used to define the combination of the number of passengers, the sitting position and the sitting posture. For example, when there is no one in the car, the measurement value is 0; when there is one person in the car and no one is lying flat, the measurement value is 1; when there is one person in the main driver and one person in the co-driver and no one is lying flat, the measurement value is 2; when there is one person in the main driver and one person on the left side of the back row and no one is lying flat, the measurement value is 3; when there is one person in the main driver and one person on the right side of the back row and no one is lying flat, the measurement value is 4. When there is one person in the main driver and one person in the co-driver, and the co-driver is sitting in a lying posture, the measurement value is 5, and so on. According to the needs of the actual application scenario, different numbers of passengers, sitting positions and sitting postures can be combined and associated with different measurement values.

[0060] Afterwards, the target air conditioning air volume and target air outlet mode of the current vehicle are determined based on the correspondence between the measured value and the air conditioning air volume and the air outlet mode. It is understandable that the correspondence can be obtained by those skilled in the art through actual measurement and pre-calibration, and this embodiment does not specifically limit this. The above-mentioned air outlet mode can be the wind direction setting of the air conditioning outlet to meet the comfort requirements of different areas and passengers in the car. Exemplarily, the air outlet mode may include a defrost mode, a face blowing mode, a foot blowing mode, etc.

[0061] Step S240, controlling the air outlet of the vehicle air conditioner according to the target air volume and the target air outlet mode.

[0062] In the related art, the air temperature, air volume and working mode of the air conditioner are often adjusted according to the external environmental conditions of the vehicle and the temperature, humidity and other parameters inside the passenger compartment and the instrument settings of the driver. In order to further realize the flexibility and initiative of air conditioning control, this embodiment can control the air outlet of the vehicle air conditioner based on the target air conditioning air volume and the target air outlet mode after completing the determination of the target air conditioning air volume and the target air outlet mode in step S230, so that the vehicle air conditioner operates according to the above target air conditioning air volume and the target air outlet mode to meet the needs of the current occupants in the vehicle. It should also be noted that when the number or position of the occupants changes again, the target air conditioning air volume and the target air outlet mode can be re-determined based on the above-mentioned occupant information such as the number of occupants, the occupant's sitting position and the sitting posture detected in real time, and the air outlet of the vehicle air conditioner can be controlled in real time.

[0063] In this way, through the above steps S210 to S240, the air volume and air outlet mode can be corrected in real time based on the monitoring of the number of passengers, the seating position and the seating posture. For example, when the number of passengers increases, the air volume can be increased; when the number of passengers decreases, the air volume can be decreased. When there are no passengers in the back row, the rear air outlet is closed, and only the front row is blown; when there are no passengers in the co-pilot, the co-pilot air outlet is closed, and only the main driver is blown. When there are passengers lying flat, the air outlet direction of the air outlet at the corresponding position can be adjusted. Therefore, a more intelligent cooling effect or heating effect, optimization of air volume, and clever adjustment of the operation of various components inside the vehicle air conditioner can be achieved according to the passenger information. When the air conditioning device of the air conditioner is not started, the temperature inside the vehicle can be maintained stable only by switching between internal and external circulation, thereby reducing energy consumption and reducing the fuel or electricity consumption of the vehicle.

[0064] In particular, in some of the embodiments, the temperature of various points in the car can be sensed by sensors according to the temperature set by the user, and the temperature inside the car can be automatically adjusted to maintain a constant temperature. By monitoring the changes of the occupants in real time, the temperature can be accurately controlled near the temperature value set by the user, thereby providing the occupants with a comfortable in-car environment at all times.

[0065] Therefore, in the above steps S210 to S240, when a change in the sitting state of the occupants in the vehicle is detected, the image signal of the occupants in the vehicle, the seat pressure signal of the occupants in the vehicle, and the infrared signal of the occupants in the vehicle are obtained; the current number of occupants in the vehicle, the occupant sitting position and the sitting posture are determined according to the image signal, the seat pressure signal and the infrared signal; the target air volume and target air outlet mode of the vehicle are determined according to the number of occupants, the occupant sitting position and the sitting posture; the air outlet of the vehicle air conditioner is controlled according to the target air volume and the target air outlet mode. It can realize real-time and active air outlet control of the vehicle air conditioner based on real-time monitoring of the number of occupants, the sitting position and the sitting posture.

[0066] In one embodiment, based on the above step S210, obtaining the image signal of the occupant inside the vehicle may include:

[0067] The visual camera device is used to collect images of the occupants inside the vehicle to obtain image signals representing the number of occupants and their sitting postures. Specifically, based on the occupant monitoring system inside the vehicle, the occupants inside the vehicle can be imaged to obtain image signals. The visual camera device can specifically be a camera device with a portrait recognition function that can distinguish the number of occupants and their postures. By introducing image acquisition inside the vehicle, multi-dimensional information acquisition can be achieved, providing richer and more detailed occupant information from the image dimension.

[0068] Additionally, in one embodiment, obtaining a seat pressure signal inside the vehicle may include:

[0069] The seat pressure sensors arranged in each seat inside the vehicle are obtained to collect seat pressure signals representing the number of occupants in the vehicle and the seating positions of the occupants.

[0070] In terms of signal processing, the seat pressure signal can be collected through the pressure sensing device (SBR) set on the vehicle seat cushion. By performing high-pass judgment on the seat pressure signal, for example, if the pressure is greater than 30kg, it can be confirmed that the corresponding seat has an occupant to prevent misjudgment caused by placing objects on the seat. In this way, the seat pressure signal that characterizes the number of occupants and the seating position inside the vehicle can be collected. This embodiment can collect signals from the dimension of the pressure sensor to improve the accuracy of judging the number of occupants and the seating position.

[0071] In one embodiment, based on the above step S220, determining the current number of passengers in the vehicle, the passenger's sitting position and sitting posture according to the image signal, the seat pressure signal and the infrared signal may include:

[0072] The current initial number of occupants and the occupant seating positions in the vehicle are determined based on the seat pressure signal; the initial number of occupants is verified based on the infrared signal and the image signal to obtain the current number of occupants in the vehicle; and the seating posture of each occupant corresponding to the occupant seating position is determined based on the image signal.

[0073] The image of the occupants inside the vehicle is collected by a visual camera device, and the collected images are subjected to portrait recognition and posture recognition to determine the number of occupants and their sitting postures. The number of occupants and their sitting positions are determined by collecting seat pressure signals from a seat pressure sensor, and the number is identified by detection by an infrared camera device. For example, if the pressure sensor and the infrared camera both detect that there is an occupant on seat A, and the image signal detects that there is a person on seat A, then one of the sitting positions is confirmed to be seat A. Afterwards, different types of signals are matched to determine the final number of occupants, the occupant's sitting position, and the sitting posture at the corresponding position. This embodiment performs mutual verification based on signals from different sources, thereby improving the accuracy of the final occupant information detection result.

[0074] In some of the embodiments, after obtaining the occupant information such as the current number of occupants, seating positions and seating postures in the above-mentioned vehicle, the occupant information can be sent to the air-conditioning control module (Climate Control Module, referred to as CCM) for subsequent air-conditioning control.

[0075] Additionally, in one embodiment, based on the above step S230, determining the target air conditioning air volume and target air outlet mode of the vehicle according to the number of passengers, the seating positions of the passengers, and the seating postures of the passengers may include:

[0076] Read the pre-established air conditioning control mapping relationship; the air conditioning control mapping relationship includes: the corresponding relationship between the combination of different occupant numbers, different occupant seating positions and different seating postures, and the air conditioning air volume and air outlet mode of the air conditioning; according to the number of occupants, the occupant seating positions and the seating postures, combined with the air conditioning control mapping relationship, determine the target air conditioning air volume and target air outlet mode corresponding to the vehicle.

[0077] The above-mentioned air conditioning control mapping relationship can be established by measuring and pre-calibrating the corresponding relationship between the air conditioning air volume, the air outlet mode and the number of passengers, the seating position and the seating posture in the actual application scenario. Afterwards, according to this air conditioning control mapping relationship, the target air conditioning air volume and the target air outlet mode corresponding to the current number of passengers, the seating position and the seating posture of the passengers are determined. In this way, the present embodiment can realize the air conditioning control that best matches the current passenger information.

[0078] In addition, in one embodiment, controlling the air outlet of the vehicle air conditioner according to the target air volume and the target air outlet mode may include:

[0079] According to the target air-conditioning air volume, the first adjustment information of the air-conditioning blower in the vehicle is determined, and the air-conditioning blower is controlled to operate according to the first adjustment information; according to the target air outlet mode, the second adjustment information of the air-conditioning outlet motor in the vehicle is determined, and the air-conditioning outlet motor is controlled to operate according to the second adjustment information.

[0080] Specifically, based on the target air-conditioning air volume, the adjustment information of the blower is controlled so that the blower operates according to the first adjustment information to achieve the above-mentioned target air-conditioning air volume; according to the target air outlet mode, the second adjustment information of the air outlet motor is controlled so that the air outlet motor operates according to the second adjustment information to achieve the above-mentioned target air outlet mode.

[0081] This embodiment can dynamically adjust the air volume and air outlet mode according to the actual passenger information of the vehicle. When there is no passenger in a seat, the air outlet related to the seat is automatically closed, and the air blowing is prohibited, so as to increase the air volume of other air outlets. When there are fewer passengers in the car, the air volume of the air conditioner can be reduced, and the air conditioner blower can be reduced in power to achieve the purpose of energy saving.

[0082] Among them, in one embodiment, first adjustment information corresponding to the target air conditioning air volume is determined based on a pre-established first mapping relationship between the air conditioning air volume and the duty cycle of the air conditioning blower; second adjustment information corresponding to the target air outlet mode is determined based on a pre-established second mapping relationship between the air outlet mode and the duty cycle of the air conditioning outlet motor.

[0083] Specifically, the air volume and the duty cycle of the air-conditioning blower have a positive correlation. When the duty cycle of the blower is 0, the blower is turned off, and the corresponding air volume is 0. When the duty cycle of the blower is 100, the blower works at full power and the air volume is maximum. Therefore, based on the above-mentioned first mapping relationship characterizing the air volume (air volume) and the duty cycle of the blower, the first adjustment information corresponding to the target air volume can be determined, that is, the duty cycle of the blower corresponding to the target air volume can be determined, and then the blower speed can be controlled to respond and operate according to the currently determined duty cycle.

[0084] In addition, the air outlet mode may include a defrosting mode, a face blowing mode, a foot blowing mode, etc. In the face blowing mode, the wind direction of the air outlet can be controlled by the air outlet motor. The wind direction of the air outlet is also divided into three modes: focusing mode, avoiding mode, and sweeping mode. The focusing mode means that the air outlet focuses on the passenger's face; the avoiding mode means that the air outlet direction avoids the passenger's body; the sweeping mode means that the air outlet direction changes from left to right.

[0085] The wind direction of the air outlet is controlled by two air outlet motors, which respectively control the air outlet in the X-axis direction and the Y-axis direction. When the motor duty cycle is 0, the X-axis remains at the far left, and the air outlet is closed, and the Y-axis remains at the top, and the air outlet is closed; when the motor duty cycle is 100, the X-axis remains fully open on the right, and the Y-axis remains at the bottom, and the air outlet is blowing. The target air outlet mode and the air outlet direction under the target air outlet mode can be determined according to the number, position, and sitting posture of the passengers. At this time, the duty cycle of the air outlet motor is controlled to make the air outlet respond to match the target air outlet mode.

[0086] Figure 3 is a flow chart of a method for controlling a vehicle air conditioner in some embodiments, such as Figure 3 As shown, the vehicle air conditioning control method includes the following steps:

[0087] Step S301: When a change in the sitting state of an occupant in the vehicle is detected, the occupant monitoring system obtains an image signal based on a visual camera device, and acquires a seat pressure signal and an infrared signal.

[0088] Step S302, determining the current number of passengers, the seating positions and the seating postures of the passengers in the vehicle according to the image signal, the seat pressure signal and the infrared signal.

[0089] Step S303, inputting the number of passengers, the seating positions and the seating postures of the passengers into the air conditioning control module to determine the measurement values ​​of the corresponding combinations.

[0090] Step S304: the air conditioning control module determines the corresponding target air conditioning air volume and target air outlet mode according to the measured value.

[0091] Step S305, determining the duty cycle adjustment information of the blower according to the target air-conditioning air volume, and controlling the blower to operate according to the duty cycle adjustment information.

[0092] Step S306, determining the duty cycle adjustment information of the air outlet motor according to the target air outlet mode, and controlling the air outlet motor to operate. Step S306 can be executed before step S305, can be executed after step S305, or can be executed simultaneously.

[0093] The above steps S301 to S306 can automatically realize real-time correction of the air volume and air outlet mode of the air conditioner according to the real-time information of the occupants.

Figure 4As shown in the figure, the intelligent cockpit system collects signals based on visual cameras, and combines seat pressure sensors and infrared cameras to determine actual passenger signals that characterize the number of passengers, their seating positions, and their seating postures. The actual passenger signals are sent to the air conditioning control module, which determines the target air conditioning air volume and target air outlet mode based on the actual passenger signals, and then controls the air conditioning blower, air conditioning outlet motor, and air conditioning temperature damper.
