Specifically, the vital sign information of the person in the vehicle cabin can be obtained through relevant state sensors provided on the vehicle, and the preset vital sign parameter range and the fourth target in-vehicle temperature can be pre-entered by the operator into relevant controllers of the vehicle, such as the air conditioning controller.

[0094] Specifically, the vital signs information of the people in the vehicle cabin obtained as mentioned above is compared with the preset vital signs parameter range. If the vital signs information of the people is lower than the lower limit of the preset vital signs parameter range, the target operating mode of the vehicle air conditioner is determined to be the sleep mode. At this time, the air volume of all air outlets of the vehicle air conditioner is controlled to be reduced, and the desired in-car temperature is set to the fourth target in-car temperature, so that the operating state of the vehicle air conditioner meets the requirement that the vital signs information of the people in the vehicle cabin is lower than the lower limit of the preset vital signs parameter range.

Specifically, the vital sign information of the person in the vehicle cabin can be obtained through relevant state sensors provided on the vehicle, and the preset vital sign parameter range and the fifth target in-vehicle temperature can be pre-entered by the operator into relevant controllers of the vehicle, such as the air conditioning controller.

[0097] Specifically, the vital signs information of the people in the vehicle cabin obtained as mentioned above is compared with the preset vital signs parameter range. If the vital signs information of the people is higher than the upper limit value of the preset vital signs parameter range, the target operation mode of the vehicle air conditioner is determined to be the sports mode. At this time, the air outlet angles of all air outlets of the air conditioner are controlled so that the air outlet range corresponding to the air outlet angle avoids the position of the people in the car, and gradually reduces the temperature in the car to the fifth target temperature, so that the operating state of the vehicle air conditioner meets the requirement that the vital signs information of the people in the vehicle cabin is higher than the upper limit value of the preset vital signs parameter range. This helps to improve the experience of the people in the vehicle cabin on the one hand, and helps to improve the intelligence of the vehicle on the other hand.

[0098] In one embodiment of the present invention, the operating mode of the vehicle air conditioner is determined based on the vital signs information of the person, and also includes: when the vehicle air conditioner is in sleep mode or exercise mode, if it is detected that the vital signs information of the person changes to meet the preset vital signs parameter range, the vehicle air conditioner is controlled to switch to normal mode.

[0099] Specifically, when the vehicle air conditioner is in sleep mode or sports mode, the vital signs information of the people in the vehicle cabin obtained above is compared with the preset vital signs parameter range. If it is detected that the vital signs information of the people changes to meet the preset vital signs parameter range, the vehicle air conditioner is controlled to switch to normal mode, so that the operating status of the vehicle air conditioner can be changed in time according to the changes in the vital signs information of the people in the vehicle cabin. The operating status of the vehicle air conditioner promptly meets the needs of the vital signs information of the people in the vehicle cabin, which helps to improve the experience of the people in the vehicle cabin on the one hand, and helps to improve the intelligence of the vehicle on the other hand.

[0100] In one embodiment of the present invention, the vital sign information of the person includes the breathing rate and / or heart rate of the person.

[0101] In a specific embodiment, the personnel information in the vehicle cabin includes the personnel vital signs information, and the personnel vital signs information includes the personnel breathing rate and / or heart rate. Specifically, the personnel vital signs information in the vehicle cabin can be obtained through relevant status sensors arranged on the vehicle.

[0102] Specifically, the vital signs information of the occupants is determined based on the acquired breathing rate and / or heart rate of the occupants in the vehicle cabin, which helps to subsequently determine the target operating mode of the vehicle air conditioner based on the vital signs information of the occupants, and then control the operating state of the vehicle air conditioner based on the target operating mode of the vehicle air conditioner, so that the operating state of the vehicle air conditioner meets the requirements of the vital signs information of the occupants in the vehicle cabin. This helps to improve the experience of the occupants in the vehicle cabin on the one hand, and helps to improve the intelligence of the vehicle on the other hand.

[0103] In one embodiment of the present invention, personal information is acquired based on a millimeter wave radar component provided in the vehicle.

[0104] In a specific embodiment, the millimeter wave radar component includes, for example, at least one millimeter wave radar. The more millimeter wave radars the millimeter wave radar component includes, the more detailed and accurate the personnel information obtained is.

[0105] Specifically, the millimeter-wave radar component installed in the vehicle is used to obtain personnel information as the basis for controlling the vehicle air-conditioning, which helps to subsequently control the vehicle air-conditioning according to the personnel information in the vehicle cabin, thereby improving the vehicle's intelligence and user experience.

[0106] In one embodiment of the present invention, the millimeter wave radar assembly includes at least one millimeter wave radar.

[0107] In a specific embodiment, the millimeter wave radar component includes at least one millimeter wave radar. The millimeter wave radar component includes one millimeter wave radar to ensure that personnel information can be obtained. The more millimeter wave radars the millimeter wave radar component includes, the more detailed and accurate the obtained personnel information is.

[0108] Specifically, the millimeter-wave radar component including at least one millimeter-wave radar installed in the vehicle obtains personnel information as the basis for controlling the vehicle air-conditioning, which helps to subsequently control the vehicle air-conditioning according to the personnel information in the vehicle cabin, thereby improving the intelligence of the vehicle and the user experience.

[0109] In one embodiment of the present invention, the millimeter wave radar includes a first millimeter wave radar and a second millimeter wave radar; the first millimeter wave radar is used to measure the information of people in the front row of the cabin; the second millimeter wave radar is used to measure the information of people in the back row of the cabin.

[0110] In a specific embodiment, the millimeter-wave radar assembly includes a first millimeter-wave radar for measuring the information of people in the front row of the cabin, and a second millimeter-wave radar for measuring the information of people in the back row of the cabin; by setting up two millimeter-wave radars to respectively detect the information of people in the front row of the cabin and the information of people in the back row of the cabin, not only can blind spots be avoided and accurate information on people can be ensured, but also waste of resources caused by excessive number can be avoided.

[0111] Specifically, based on the first millimeter-wave radar installed in the vehicle for measuring the information of people in the front row of the cabin, and the second millimeter-wave radar for measuring the information of people in the back row of the cabin, the personnel information is obtained as the basis for controlling the vehicle air-conditioning, which helps to control the vehicle air-conditioning according to the personnel information in the vehicle cabin, thereby improving the intelligence of the vehicle and the user experience.

[0112] In one embodiment of the present invention, the first millimeter-wave radar is arranged near the rearview mirror on the passenger side of the vehicle; the second millimeter-wave radar is arranged above the B-pillar on the driver's side of the vehicle.

[0113] Specifically, the first millimeter-wave radar is set near the rearview mirror on the passenger side of the vehicle to facilitate the measurement of information about people in the front row of the cabin, and the second millimeter-wave radar is set above the B-pillar on the driver's side of the vehicle to facilitate the measurement of information about people in the back row of the cabin.

[0114] Figure 2 FIG. 1 is a flow chart of a method for controlling a vehicle air conditioner according to a specific embodiment of the present invention. Figure 2 As shown, in a specific embodiment of the present invention, the control method of the vehicle air conditioner includes:

[0115] Step S10: Obtaining the personnel information in the vehicle cabin.

[0116] Step S11: According to the personnel information in the vehicle cabin, determine the number of personnel, personnel positions, personnel volumes and personnel vital signs information in the vehicle cabin.

[0117] Step S12: Based on the number of people, their positions, their sizes, and their vital signs in the vehicle cabin, the air volume, air temperature, and air angle of the vehicle air conditioner are controlled.

[0118] Specifically, the vehicle air conditioner control method provided in this specific embodiment is divided into two parts: a perception method and a function implementation method.

[0119] Among them, the perception method is implemented using millimeter-wave radar. As a common sensor, millimeter-wave radar has the advantages of high resolution, good privacy, and small size. Since targets at different locations have different signal-to-noise ratios and the strength of the echo signal is also different, based on the radar principle, the distance, speed, phase, angle and other information of users at different locations can be measured. In the early stage of radar design, modules such as RF, flash memory, main chip, and power management chip are integrated into a PCB board to reduce the space occupied by the radar in the car.

[0120] For the FMCW (Frequency Modulated Continuous Wave) radar system, a frequency modulated sequence waveform is emitted, and the received reflected signal is analyzed and processed. By sampling each frame of the radar intermediate frequency signal, the sampled data is subjected to FFT (Fast Fourier Transformation) to obtain the target quantity and distance information. After removing the clutter, the data after 2D FFT is used to obtain the speed dimension information of the people in the cabin. Based on the above operations, DOA (Direction of Arrival) is analyzed to obtain the angle information. Based on the above process, the human body data information of the people in the car in the corresponding area can be collected, and the information includes: the number of people, the location of people, the volume of people, and the vital signs of people (heartbeat and breathing signals).

[0121] Personnel volume: During radar detection, target information in distance, speed, and angle dimensions can be referenced. In a stationary state, the radar can use a development solution with high angular resolution performance to analyze the angle after solving the angle to obtain the user's shape and size.

[0122] Personnel location: The detection area of ​​the vehicle is divided according to the number of seats, and the analysis of the personnel activity range will be based on the seat area where the user is located. Since the relative speed is constantly changing in dynamic scenes, the phase change of the signal is sensitive, and the accuracy of detecting signal changes is higher. Therefore, in a dynamic state, the radar can analyze the speed changes caused by the user's movement to analyze the occupancy of personnel, so as to determine whether there are people in different areas.

[0123] Number of people: After generating point cloud data carrying user information, the point cloud information belonging to different targets is clustered through a clustering algorithm. The number of people in the cabin can be determined based on the distribution of the point cloud in different areas.

[0124] Heartbeat and breathing: When the human body breathes and the heart beats, it causes tiny displacements of the chest and abdomen. These tiny displacements will affect the phase of specific signals. The breathing and heartbeat signals can be extracted through the phase changes of the FMCW signal on a specific range gate.

[0125] Specifically, the normal breathing frequency of an adult is 0.1-0.5 Hz, and the chest movement amplitude is 1-12 mm; the normal heart rate of an adult is 0.8-2.0 Hz, and the chest movement amplitude is 0.1-0.5 mm. By separating breathing and heartbeat in the time domain at different frequencies, the heartbeat signal is an impulse signal, and holding your breath can extract the fundamental frequency component of the heartbeat.

[0126] The amplitude of the breathing signal is relatively large and is easier to obtain than the heartbeat. Occupancy status: By analyzing the point cloud data generated after the signal processing algorithm and checking the distribution of point clouds in different areas, the occupancy status of each area can be obtained.

[0127] Function implementation method: Place a millimeter-wave radar at the co-pilot seat of the vehicle to detect people in the first row of cabin. Place a millimeter-wave radar behind the driver's seat to detect people in the back row of cabin. For the front area of ​​the cabin, place the radar on the side of the cabin rearview mirror of the co-pilot seat of the vehicle to detect the occupant information of the driver and co-pilot seats. By changing the parameter weights of the array, the antenna beam direction is set to the driver's seat direction; for the rear area of ​​the cabin, place the radar above the left side of the B-pillar of the vehicle, and its antenna beam direction is set to the middle rear passenger to detect the personnel information of the rear passengers. This greatly reduces the conflict impact that may be caused when two millimeter-wave radars transmit signals at the same time, and maximizes the coverage of the detection area in the vehicle. The specific installation diagram is shown below. Figure 3 As shown in the figure, the two circles are the installation locations of the two millimeter-wave radars, and the two sectors are the detection areas of the two millimeter-wave radars.

[0128] When the radar detects the human body information in the cabin, the information is sent to the vehicle through the CAN (Controller Area Network) network. After the vehicle receives the message information, it sends it to the air conditioning control module to control each air outlet. The method for realizing each function of the vehicle air conditioner in the specific embodiment of the present invention performs the following processes in sequence:

[0129] 1. After obtaining the information on the number of people, when it is determined that the temperature inside the car increases or decreases with the number of people, the air outlet temperature is appropriately lowered or increased simultaneously to control the temperature inside the cabin to maintain a comfortable state for the human body.

[0130] 2. The location information of the people in the cabin. When the distribution of point cloud data detects that there are people in a specific area, open the air outlet at that location, turn on the in-car circulation mode and gradually increase the air volume to a comfortable range for the human body; intelligently adjust the air supply range of the vehicle air conditioner based on the information obtained, and turn the air outlet direction to the body area of ​​the people in the car to avoid direct air conditioning. At the same time, the air conditioner should appropriately adjust the air outlet range of the air conditioner according to the user shape sensed by the radar. When the radar recognizes that the user in a specific area is slightly larger, the wind shelter range will be increased; when it is recognized that the user in a specific area is slightly smaller, the wind shelter range will be appropriately reduced.

[0131] 3. Set the normal threshold, sleep threshold, and exercise threshold of vital sign signals, and make judgments based on the heartbeat and breathing signals obtained.

[0132] Specifically, when the radar identifies that the vital signs of the people in the car are within the normal range: the normal breathing rate of an adult is 0.1 to 0.5 Hz, and the chest movement amplitude is 1 to 12 mm; the normal heart rate of an adult is 0.8 to 2.0 Hz, and the chest movement amplitude is 0.1 to 0.5 mm.

[0133] When the vehicle air conditioner is turned on in normal mode, the vehicle air conditioner should lower the air outlet at the position where the person is identified and increase the air volume in the remaining range. When the identified vital signs information is lower than the above frequency range, the air conditioner executes the sleep mode: reduce the overall air volume and adjust the current temperature to a comfortable temperature for the human body. When the identified vital signs information is higher than the above frequency range, the air conditioner executes the motion mode: dynamically adjust the air outlet angle according to the movement in the cabin, avoid direct blowing of the air conditioner and increase the air volume to gradually reduce the temperature of the whole vehicle. When the vital signs information of the people in the car is identified to return to the normal range, the air conditioner continues to execute the normal mode.

[0134] In summary, the control method of the vehicle air conditioner according to the embodiment of the present invention first obtains the information of the people in the vehicle cabin as the basis for controlling the vehicle air conditioner, and then controls the vehicle air conditioner according to the information of the people in the vehicle cabin, so that the vehicle air conditioner can be intelligently adjusted according to the information of the people in the vehicle cabin; thereby, on the one hand, it helps to improve the experience of the people in the vehicle cabin, and on the other hand, it helps to improve the intelligence level of the vehicle.
