Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and in particular, relates to a control method, device, electronic equipment and vehicle for a blowing system. Background Art

[0002] With the development of science and technology, the automobile market is currently in a stage of rapid growth, and the proportion of families owning cars is increasing. As family members travel by car more and more, whether they are prone to motion sickness has become an important consideration when buying a car.

[0003] In the related art, the possibility of motion sickness is reduced mainly by improving the suspension system of the vehicle to reduce the bumps and swaying during driving. However, since the causes of motion sickness are complex and involve the physiological reactions of the human body, the effect of improving the suspension system of the vehicle to alleviate the motion sickness of the driver and passengers is limited. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a control method, device, electronic device and vehicle of a blowing system to reduce the possibility of motion sickness of the driver and passengers and improve the comfort of the driver and passengers.

[0005] In a first aspect, the present application provides a control method for a blowing system, wherein the blowing system includes a plurality of air outlets, and the method includes:

[0006] Determining the air outlet mode of the blowing system according to the blocking condition of the target air outlet; wherein at least part of the air outlets used for air outlet in different air outlet modes are different;

[0007] Analyzing the current motion state of the vehicle according to the acceleration data of the vehicle;

[0008] The blowing system is controlled to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state in the air outlet mode.

[0009] According to the control method of the blowing system of the present application, the blowing mode of the blowing system is determined according to the blocking condition of the target air outlet; wherein, at least part of the air outlets used in different blowing modes are different; the current motion state of the vehicle is analyzed according to the acceleration data of the vehicle; and the blowing system is controlled to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state under the blowing mode. The embodiment of the present application can simulate the wind direction of the human body movement process by controlling the blowing system to blow air to the driver and passengers during the driving of the vehicle, which helps the brain integrate the information of the visual, vestibular and human sensory systems, and reduce the dizziness of the driver and passengers caused by the movement of the vehicle. The blowing mode is flexibly selected according to the blocking condition of the target air outlet and the blowing mode is adjusted according to the current motion state of the vehicle, which can improve the blowing efficiency and more realistically simulate the wind direction of the human body movement process, thereby reducing the possibility of motion sickness of the driver and passengers and improving the comfort of the driver and passengers.

[0010] According to an embodiment of the present application, determining the air outlet mode of the blowing system according to the blocking condition of the target air outlet includes:

[0011] Obtaining the head size of the driver and the collected neck area of ​​the driver and the occupant;

[0012] estimating the neck area of ​​the driver and passenger according to the head size;

[0013] Determining the blocking condition of the target air outlet according to the collected neck area of ​​the driver and occupant and the estimated neck area of ​​the driver and occupant;

[0014] The air outlet mode of the blowing system is determined according to the shielding condition.

[0015] In this embodiment, by obtaining the head size and neck area information of the driver and passenger, the blocking condition of the air outlet can be estimated more accurately, thereby determining the air outlet mode more reasonably.

[0016] According to an embodiment of the present application, the air outlet mode includes at least a first air outlet mode and a second air outlet mode;

[0017] In the case where it is determined that the target air outlet is blocked, determining the air outlet mode to be the first air outlet mode, and in the first air outlet mode, closing the target air outlet and the air outlet associated with the target air outlet;

[0018] When it is determined that the target air outlet is not blocked, the air outlet mode is determined to be the second air outlet mode.

[0019] In this embodiment, the air-conditioning outlet mode is intelligently adjusted according to the actual situation in the vehicle. When it is detected that the target air outlet is blocked, it will automatically switch to the first air outlet mode and close the air outlet in the blocked direction, thereby reducing ineffective air blowing and saving energy. When the target air outlet is not blocked, the system will switch to the second air outlet mode to further improve the blowing effect.

[0020] According to an embodiment of the present application, before determining the air outlet mode of the blowing system according to the blocking condition of the air outlet, the method includes:

[0021] Obtain current sensor information of seats in the vehicle;

[0022] Determining whether the seat is occupied by a driver or a passenger based on the current sensor information and the sensor information when no one is sitting on the seat;

[0023] When a driver or passenger is seated on the seat, the blowing function of the blowing system is turned on.

[0024] In this embodiment, by acquiring the current sensor information of the seats in the vehicle and comparing it with the sensor information when no one is sitting in the seat, it is possible to accurately determine whether the seat is occupied by a driver or passenger. When a driver or passenger is detected, the blowing system is automatically turned on, which not only improves the comfort of the passengers but also helps to reduce energy waste.

[0025] According to one embodiment of the present application, analyzing the current motion state of the vehicle according to the acceleration data of the vehicle includes:

[0026] Obtaining the acceleration magnitude and acceleration direction of the vehicle;

[0027] The current motion state of the vehicle is analyzed according to the acceleration magnitude and the acceleration direction.

[0028] In this embodiment, by analyzing the acceleration magnitude and acceleration direction of the vehicle, the current motion state of the vehicle can be accurately determined.

[0029] According to one embodiment of the present application, the acceleration data includes a lateral acceleration of the vehicle and a longitudinal acceleration of the vehicle; combinations of different lateral acceleration magnitude ranges, different lateral acceleration directions, different longitudinal acceleration magnitude ranges and different longitudinal acceleration directions correspond to different motion states of the vehicle.

[0030] In this embodiment, by comprehensively analyzing the lateral acceleration and longitudinal acceleration data of the vehicle, the lateral acceleration data reflects the lateral force of the vehicle when turning, while the longitudinal acceleration data indicates the acceleration or deceleration of the vehicle when driving in a straight line. By carefully analyzing the size and direction of these two accelerations, the various motion states of the vehicle can be accurately identified, thereby realizing intelligent control of the blowing system to reduce the discomfort of passengers caused by the movement of the vehicle.

[0031] According to one embodiment of the present application, different blowing modes correspond to different blowing parameters; the blowing parameters include blowing speed and blowing direction; the blowing speed is adapted to the longitudinal acceleration of the vehicle, and the blowing direction is adapted to the lateral acceleration of the vehicle.

[0032] In this embodiment, by comprehensively analyzing the longitudinal acceleration and lateral acceleration of the vehicle, it is possible to accurately identify different motion states of the vehicle, such as steady driving, acceleration, deceleration or turning. The blowing speed is adapted to the longitudinal acceleration of the vehicle, so that when the vehicle accelerates or decelerates, the blowing speed can be adjusted to match the movement changes of the vehicle to maintain the comfort of the driver and passengers. For example, during rapid acceleration or deceleration, increasing the blowing speed may help stabilize the passengers' feelings and reduce motion sickness. The blowing direction is adapted to the lateral acceleration of the vehicle, so that when the vehicle turns, the blowing direction is adjusted to help the driver and passengers maintain a sense of balance and reduce the discomfort caused by turning, thereby further reducing the possibility of motion sickness of the driver and passengers and improving the comfort of the driver and passengers.

[0033] According to one embodiment of the present application, the blowing direction of the blowing system is adjusted by controlling the start and stop of different blowing outlets; or, the blowing direction of the blowing system is adjusted by controlling the air outlet angle of the blowing outlet.

[0034] In this embodiment, according to the setting and layout of the blowing outlets, the blowing direction can be adjusted by controlling the start and stop of different blowing outlets, or by controlling the air outlet angle of the blowing outlets to adjust the blowing direction, thereby achieving flexible adjustment of the blowing direction.

[0035] According to one embodiment of the present application, before controlling the blowing system to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state in the air outlet mode, the method includes:

[0036] Obtaining the corresponding relationship between the motion state of the vehicle and the blowing mode in the air outlet mode;

[0037] The blowing mode corresponding to the current motion state is matched from the corresponding relationship.

[0038] In this embodiment, by obtaining the correspondence between the vehicle's motion state and the blowing method in the wind outlet mode, and matching the blowing method in the current motion state from these correspondences, the blowing method can be adjusted in time when the vehicle's motion state changes, thereby improving the adjustment efficiency of the blowing method.

[0039] According to an embodiment of the present application, when the current motion state is straight-moving at a constant speed, the blowing mode is no blowing;

[0040] When the current motion state is not straight-ahead motion at a constant speed, the blowing direction of the blowing method is adapted to the lateral acceleration of the vehicle.

[0041] In this embodiment, by choosing not to blow air when the vehicle is moving straight at a constant speed, unnecessary air flow interference can be reduced, energy consumption can be reduced, and the discomfort caused by long-term blowing of air to the driver and passengers can be reduced. When the vehicle is not moving straight at a constant speed, the blowing direction is adjusted according to the lateral acceleration of the vehicle to adapt to the vehicle's turning or lane changing operations, which helps to reduce the swaying feeling of passengers caused by the change of the lateral acceleration of the vehicle, and can provide passengers with an additional "sense of support" when the vehicle turns, helping the driver and passengers to maintain balance, thereby reducing the risk of motion sickness.

[0042] According to one embodiment of the present application, the blowing system includes at least a front air outlet and a rear air outlet; the front air outlet is arranged on the back of the front seat, the ceiling inside the vehicle and / or is suspended between multiple front seats; the rear air outlet is arranged on the rear seat headrest and / or the ceiling inside the vehicle.

[0043] In this embodiment, by arranging the front air outlets and the rear air outlets at different positions of the vehicle, it helps to improve the air circulation efficiency in the vehicle.

[0044] According to one embodiment of the present application, when the air outlet mode is the first air outlet mode, the front air outlet is opened to blow air towards the face of the driver and the passenger, and the blowing direction and the blowing angle of the blowing mode towards the face of the driver and the passenger are adapted to the lateral acceleration of the vehicle.

[0045] In this embodiment, by opening the front air outlet in the first air outlet mode and blowing air towards the driver and passenger's face, the blowing angle towards the driver and passenger's face is adapted to the lateral acceleration of the vehicle, which can simulate the wind direction during human movement, help reduce the swaying feeling of passengers caused by changes in the lateral acceleration of the vehicle, thereby reducing the possibility of motion sickness of the driver and passenger and improving the comfort of the driver and passenger.

[0047] In this embodiment, by opening the front air outlet to blow air directly toward the driver and passenger's face and opening the rear air outlet to blow air toward the driver and passenger's neck in the second air outlet mode, the wind direction during human movement can be simulated more carefully. The blowing angles toward the driver and passenger's face and the blowing angles toward the driver and passenger's neck are adapted to the lateral acceleration of the vehicle, which helps to reduce the swaying feeling of the passengers caused by the change in the lateral acceleration of the vehicle, thereby reducing the possibility of motion sickness of the driver and passenger and improving the comfort of the driver and passenger.

[0048] According to one embodiment of the present application, when the air outlet mode is the second air outlet mode, if the movement state of the vehicle includes vehicle acceleration, the front air outlet is opened to blow air toward the face of the driver and passenger; if the movement state of the vehicle includes vehicle deceleration, the rear air outlet is opened to blow air toward the neck of the driver and passenger.

[0049] In this embodiment, by deciding to open the front or rear air outlet according to the acceleration or deceleration of the vehicle in the second air outlet mode, and blowing air toward the face or neck in a targeted manner, the wind direction during human movement can be simulated more carefully, which helps the brain integrate information from the visual, vestibular and human sensory systems, reduce the dizziness of the driver and passengers caused by the movement of the vehicle, thereby reducing the possibility of motion sickness and improving the comfort of the driver and passengers.

[0053] The control module is used to control the blowing system to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state in the air outlet mode.

The embodiment of the present application can simulate the wind direction of the human body movement process by controlling the blowing system to blow air to the driver and passengers during the driving of the vehicle, which helps the brain integrate the information of the visual, vestibular and human sensory systems, and reduce the dizziness of the driver and passengers caused by the movement of the vehicle. The blowing mode is flexibly selected according to the blocking condition of the target air outlet and the blowing mode is adjusted according to the current motion state of the vehicle, which can improve the blowing efficiency and more realistically simulate the wind direction of the human body movement process, thereby reducing the possibility of motion sickness of the driver and passengers and improving the comfort of the driver and passengers.

[0062] The above one or more technical solutions in the embodiments of the present application have at least one of the following technical effects:

[0063] According to the control method of the blowing system of the present application, the blowing mode of the blowing system is determined according to the blocking condition of the target air outlet; wherein, at least part of the air outlets used in different blowing modes are different; the current motion state of the vehicle is analyzed according to the acceleration data of the vehicle; and the blowing system is controlled to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state under the blowing mode. The embodiment of the present application can simulate the wind direction of the human body movement process by controlling the blowing system to blow air to the driver and passengers during the driving of the vehicle, which helps the brain integrate the information of the visual, vestibular and human sensory systems, and reduce the dizziness of the driver and passengers caused by the movement of the vehicle. The blowing mode is flexibly selected according to the blocking condition of the target air outlet and the blowing mode is adjusted according to the current motion state of the vehicle, which can improve the blowing efficiency and more realistically simulate the wind direction of the human body movement process, thereby reducing the possibility of motion sickness of the driver and passengers and improving the comfort of the driver and passengers.

[0064] Furthermore, in some embodiments, by intelligently adjusting the air-conditioning outlet mode according to the actual situation in the vehicle, when it is detected that the target air outlet is blocked, it will automatically switch to the first outlet mode and close the air outlet in the blocked direction, which can reduce ineffective air blowing and save energy. When the target air outlet is not blocked, the system will switch to the second outlet mode to further improve the blowing effect.

[0065] Furthermore, in some embodiments, by comprehensively analyzing the lateral acceleration and longitudinal acceleration data of the vehicle, the lateral acceleration data reflects the lateral force of the vehicle when turning, while the longitudinal acceleration data indicates the acceleration or deceleration of the vehicle when driving in a straight line. By carefully analyzing the size and direction of these two accelerations, the various motion states of the vehicle can be accurately identified, thereby realizing intelligent control of the blowing system to reduce the discomfort caused to passengers by the movement of the vehicle.

[0066] Furthermore, in some embodiments, by comprehensively analyzing the longitudinal acceleration and lateral acceleration of the vehicle, it is possible to accurately identify different motion states of the vehicle, such as steady driving, acceleration, deceleration, or turning. The blowing speed is adapted to the longitudinal acceleration of the vehicle, so that when the vehicle accelerates or decelerates, the blowing speed can be adjusted to match the movement changes of the vehicle to maintain the comfort of the driver and passengers. For example, during sudden acceleration or deceleration, increasing the blowing speed may help stabilize the passengers' feelings and reduce motion sickness. The blowing direction is adapted to the lateral acceleration of the vehicle, so that when the vehicle turns, the blowing direction is adjusted to help the driver and passengers maintain a sense of balance and reduce the discomfort caused by turning, thereby further reducing the possibility of motion sickness of the driver and passengers and improving the comfort of the driver and passengers.

[0067] Furthermore, in some embodiments, by not blowing air when the vehicle is moving straight at a constant speed, unnecessary airflow interference can be reduced, energy consumption can be reduced, and the discomfort caused by long-term blowing of air to the driver and passengers can be reduced. When the vehicle is not moving straight at a constant speed, the blowing direction is adjusted according to the lateral acceleration of the vehicle to adapt to the vehicle's turning or lane changing operations, which helps to reduce the swaying feeling of passengers caused by changes in the lateral acceleration of the vehicle, and can provide passengers with an additional "sense of support" when the vehicle turns, helping the driver and passengers to maintain balance, thereby reducing the risk of motion sickness.

[0068] Furthermore, in some embodiments, by opening the front air outlet in the first air outlet mode and blowing air toward the driver and passenger's face, the blowing angle toward the driver and passenger's face is adapted to the lateral acceleration of the vehicle, which can simulate the wind direction during human movement, help reduce the swaying feeling of passengers caused by changes in the lateral acceleration of the vehicle, thereby reducing the possibility of motion sickness for the driver and passenger and improving the comfort of the driver and passenger.

[0069] Furthermore, in some embodiments, by opening the front air outlet to blow air directly toward the driver and passenger's face and opening the rear air outlet to blow air toward the driver and passenger's neck in the second air outlet mode, the wind direction during human movement can be simulated more carefully, and the blowing angles toward the driver and passenger's face and the blowing angles toward the driver and passenger's neck are adapted to the lateral acceleration of the vehicle, which helps to reduce the swaying feeling of the passengers caused by the change in the lateral acceleration of the vehicle, thereby reducing the possibility of motion sickness of the driver and passenger and improving the comfort of the driver and passenger.

[0070] Furthermore, in some embodiments, by deciding to open the front or rear air outlet according to the acceleration or deceleration of the vehicle in the second air outlet mode, and blowing air toward the face or neck in a targeted manner, the wind direction during human movement can be simulated more carefully, which helps the brain integrate information from the visual, vestibular and human sensory systems, reduce the dizziness caused by vehicle movement, thereby reducing the possibility of motion sickness and improving the comfort of the driver and passengers.

[0097] like Figure 1 As shown, the control method of the blowing system includes: step 110, step 120 and step 130.

[0098] Step 110: determine the air outlet mode of the blowing system according to the shielding condition of the target air outlet; wherein at least part of the air outlets used for air outlet in different air outlet modes are different.

[0099] In the embodiment of the present application, the blowing system may be a device for adjusting the air flow in the vehicle, and the blowing system can provide a comfortable in-vehicle environment for the driver and passengers by controlling the direction and / or intensity of the airflow. The blowing system may include components such as a fan, a motor, and an air outlet.

[0100] In some embodiments, the blowing system may have multiple blowing outlets, which may be arranged near the seat cushions of the vehicle, on the back of the seat of the vehicle, on the roof of the vehicle, and so on.

[0101] In some embodiments, Figure 2 As shown, the blowing system includes at least a front air outlet and a rear air outlet. The front air outlet is arranged on the back of the front seat, the ceiling inside the vehicle and / or suspended between multiple front seats; the rear air outlet is arranged on the rear seat headrest and / or the ceiling inside the vehicle.

[0102] In this embodiment, the vehicle may include multiple rows of seats, the first row of seats includes the main driver's seat and the front passenger seat, and the second row of seats is a row of seats located behind the first row of seats. Of course, in some vehicles, the second row of seats also includes a third row of seats, or more rows of seats. The embodiment of the present application does not limit the number of rows of seats in the vehicle.

[0103] In the embodiments of the present application, the front row seats and the rear row seats do not refer to a specific row of seats, but two rows of seats with front-to-back relative positions. For example, for the first row of seats and the second row of seats, the front row seats refer to the first row of seats, and the rear row seats refer to the second row of seats; for the second row of seats and the third row of seats, the front row seats refer to the second row of seats, and the rear row seats refer to the third row of seats.

[0104] In an embodiment of the present application, for a seat, the front air outlet may be the air outlet located in the direction of the seat pointing to the front of the vehicle, and the rear air outlet may be the air outlet located in the direction of the seat back.

[0105] like Figure 3 As shown, the front air outlet can be arranged on the back of the front seat, or can be hung between multiple front seats through an external hanging device. Figure 4 As shown, the front air outlet can also be arranged on the roof of the vehicle. Figure 5 As shown, the front air outlet can also be arranged on the side of the seat.

[0106] The rear air outlet can be set on the rear seat headrest or on the interior ceiling. With the front direction of the vehicle as the front, the front air outlet is located in front of the rear air outlet. The number of front air outlets can be one or more, and the number of rear air outlets can be one or more.

[0107] It should be noted that the seats in the vehicle may share a set of front air outlets and rear air outlets, or the seats in the vehicle may each correspond to a set of front air outlets and rear air outlets. For the first row of seats, the front air outlets may also be set near the dashboard, A-pillar or B-pillar, and the rear air outlets may be set at the back of the first row of seats, such as the headrest.

[0108] The front air outlet can face the seat, and when the front air outlet is blowing air, the wind can be blown from the front of the driver and passenger sitting on the seat to the driver and passenger sitting on the seat; the rear air outlet can face the front of the seat, and when the rear air outlet is blowing air, the wind can be blown from the back of the driver and passenger sitting on the seat to the driver and passenger sitting on the seat.

[0109] In this embodiment, by arranging the front air outlets and the rear air outlets at different positions of the vehicle, it helps to improve the air circulation efficiency in the vehicle.

[0110] In the embodiment of the present application, the target air outlet may be a specific air outlet in the air blowing system, and the specific air outlet may be an air outlet that is easily blocked. For example, if the rear air outlet is set at the seat cushion, the air outlet is easily blocked by the head of the driver and the passenger, and the target air outlet may be the rear air outlet. If the target air outlet is blocked, the air outlet mode needs to be adjusted to reduce the situation of ineffective air blowing.

[0111] In an embodiment of the present application, a sensor may be arranged within a preset range of the target air outlet, and the sensor may be used to detect whether there is an obstacle in front of the target air outlet, thereby determining the obstruction condition of the target air outlet.

[0112] In the embodiment of the present application, the blowing system may include multiple blowing modes, and different blowing modes use different at least some air outlets when blowing. For example, when the target air outlet is blocked, a certain blowing mode may be entered, in which at least the target air outlet is closed, or at least the blowing speed or intensity of the target air outlet is adjusted.

[0113] Step 120: Analyze the current motion state of the vehicle according to the acceleration data of the vehicle.

[0114] In the embodiments of the present application, Figure 2 As shown, the acceleration data of the vehicle can be obtained through the acceleration sensor, which can measure the acceleration changes of the vehicle on three axes (X-axis, Y-axis and Z-axis), where the X-axis represents the longitudinal direction of the vehicle, that is, the direction from the rear of the vehicle to the front of the vehicle, the Y-axis represents the lateral direction of the vehicle, that is, the direction perpendicular to the direction from the rear of the vehicle to the front of the vehicle, and the Z-axis represents the direction of gravity.

[0115] The current state of motion of the vehicle can be analyzed based on the acceleration data. For example, analyzing the acceleration data of a vehicle can help determine whether the vehicle is accelerating, decelerating, or maintaining a constant speed. A positive value of acceleration indicates that the vehicle is accelerating, a negative value indicates that the vehicle is decelerating, and a value close to zero may indicate that the vehicle's speed is relatively stable.

[0116] Step 130: Control the blowing system to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state in the air outlet mode.

[0117] In the embodiment of the present application, the blowing mode of the blowing system and the different blowing modes of the blowing mode take into account the motion state of the vehicle, because different motion states (such as acceleration, deceleration, turning, etc.) may affect the comfort and motion sickness of the driver and passengers. By intelligently controlling the blowing system, the blowing mode can be adjusted according to the motion state of the vehicle to improve the comfort of the driver and passengers and reduce the possibility of motion sickness.

[0118] In the embodiment of the present application, the selection of the blowing mode matches the current motion state of the vehicle. For example, when the vehicle accelerates or decelerates, the wind direction and intensity can be adjusted to simulate the wind direction during human motion, helping the brain integrate information from the visual, vestibular and human sensory systems, and reducing motion sickness.

[0119] In some embodiments, the blowing modes corresponding to different motion states under different air outlet modes can be pre-configured, and the blowing modes corresponding to different motion states under different air outlet modes can be optimized configurations obtained in advance through a large number of experiments. After determining the air outlet mode and the current motion state of the vehicle, the corresponding blowing mode can be determined according to the pre-configured information. It is also possible to train a deep learning model by default, and after inputting the air outlet mode and the current motion state of the vehicle into the deep learning model, the blowing mode output by the deep learning model can be obtained. Of course, the blowing mode corresponding to the current motion state can also be determined by other methods, and the embodiments of the present application are not limited to this.

[0120] According to the control method of the blowing system of the present application, the blowing mode of the blowing system is determined according to the blocking condition of the target air outlet; wherein, at least part of the air outlets used in different blowing modes are different; the current motion state of the vehicle is analyzed according to the acceleration data of the vehicle; and the blowing system is controlled to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state under the blowing mode. The embodiment of the present application can simulate the wind direction of the human body movement process by controlling the blowing system to blow air to the driver and passengers during the driving of the vehicle, which helps the brain integrate the information of the visual, vestibular and human sensory systems, and reduce the dizziness of the driver and passengers caused by the movement of the vehicle. The blowing mode is flexibly selected according to the blocking condition of the target air outlet and the blowing mode is adjusted according to the current motion state of the vehicle, which can improve the blowing efficiency and more realistically simulate the wind direction of the human body movement process, thereby reducing the possibility of motion sickness of the driver and passengers and improving the comfort of the driver and passengers.

[0121] In some embodiments, determining the air outlet mode of the blowing system according to the blocking condition of the target air outlet includes:

[0122] Obtain the head size of the driver and the collected neck area of ​​the driver and the passenger;

[0123] Estimate the neck area of ​​the driver and passenger based on the head size;

[0124] Determine the blocking condition of the target air outlet according to the collected neck area of ​​the driver and the estimated neck area of ​​the driver and the occupant;

[0125] Determine the air outlet mode of the blowing system according to the blocking conditions.

[0126] In this embodiment, if Figure 2 As shown, an occupant monitoring sensor can be set within a preset range of the target air outlet, or an on-board camera inside the vehicle can be used to obtain an image including the driver and occupants, and image processing technology can be used to calculate the head size of the driver and occupant in the image and the neck area of ​​the driver and occupant in the image.

[0127] Based on the acquired head size data, the neck area can be estimated using an algorithm or a preset proportional relationship. For example, the head size and the neck area can be correlated based on ergonomic data to predict the approximate size of the neck.

[0128] The obstruction of the target air outlet is determined by comparing the collected neck area of ​​the driver and the estimated neck area of ​​the driver and the occupant. For example, the ratio of the collected neck area of ​​the driver and the estimated neck area of ​​the driver and the occupant can be calculated. If the ratio exceeds a preset ratio, it can be determined that there is no obstruction; if it is less than or equal to the preset ratio, it can be determined that there is obstruction.

[0129] In some embodiments, when it is determined that the target air outlet is blocked, a buzzer can be used to sound a reminder to remind the driver and passenger that their neck is blocking the target air outlet, and after a preset period of time, the blockage situation behind the target outlet can be determined, and the air outlet mode of the blowing system can be adjusted according to the blockage situation.

[0130] In this embodiment, by obtaining the head size and neck area information of the driver and passenger, the blocking condition of the air outlet can be estimated more accurately, thereby determining the air outlet mode more reasonably.

[0131] In some embodiments, the air outlet mode includes at least a first air outlet mode and a second air outlet mode;

[0132] When it is determined that the target air outlet is blocked, the air outlet mode is determined to be the first air outlet mode, and in the first air outlet mode, the target air outlet and the air outlet associated with the target air outlet are closed;

[0133] When it is determined that the target air outlet is not blocked, the air outlet mode is determined to be the second air outlet mode.

[0134] In this embodiment, at least some of the air outlets used for air outlet in different air outlet modes are different. When the target air outlet is blocked, the target air outlet and the blowing outlet associated with the target air outlet can be closed. The blowing outlet associated with the target air outlet is the air outlet in the same row as the target air outlet. For example, if the target air outlet is the front air outlet, the blowing outlet associated with the target air outlet is the front air outlet. If the target air outlet is the rear air outlet, the blowing outlet associated with the target air outlet is the rear air outlet.

[0135] In this embodiment, if it is detected that the target air outlet is not blocked, the second air outlet mode can be selected. In the second air outlet mode, the number of air outlets used for air outlet is greater than that used in the first air outlet mode to provide more comprehensive airflow coverage and improve the comfort of the driver and passengers.

[0136] In this embodiment, the air-conditioning outlet mode is intelligently adjusted according to the actual situation in the vehicle. When it is detected that the target air outlet is blocked, it will automatically switch to the first air outlet mode and close the air outlet in the blocked direction, thereby reducing ineffective air blowing and saving energy. When the target air outlet is not blocked, the system will switch to the second air outlet mode to further improve the blowing effect.

[0137] In some embodiments, before determining the air outlet mode of the blowing system according to the blocking condition of the air outlet, the method includes:

[0138] Obtain current sensor information of seats in the vehicle;

[0139] Determine whether there is a driver or passenger in the seat based on current sensor information and sensor information when no one is sitting in the seat;

[0140] When there are passengers in the seats, turn on the blowing function of the blowing system.

[0141] In this embodiment, a sensor may be provided in each seat of the vehicle to detect whether there is someone sitting in the seat. The current sensing information of the seat in the vehicle may be obtained through the sensor, and the sensing information may be different depending on the type of sensor. For example, the sensor may be a pressure sensor, an infrared sensor or a capacitive sensor, and the sensing information may be a pressure value, a temperature value, etc.

[0142] After obtaining the current sensor information of the seat in the vehicle, the current sensor information can be compared with the sensor information when no one is sitting. For example, if the sensor information is a pressure value, if the current sensor information shows that the pressure value is greater than the preset value compared to the pressure value when no one is sitting, it can be determined that there is a driver or passenger sitting on the seat. When there is a driver or passenger sitting on the seat, the blowing function of the blowing system is turned on.

[0143] In this embodiment, by acquiring the current sensor information of the seats in the vehicle and comparing it with the sensor information when no one is sitting in the seat, it is possible to accurately determine whether the seat is occupied by a driver or passenger. When a driver or passenger is detected, the blowing system is automatically turned on, which not only improves the comfort of the passengers but also helps to reduce energy waste.

[0144] In some embodiments, analyzing the current motion state of the vehicle according to the acceleration data of the vehicle includes:

[0145] Get the acceleration magnitude and direction of the vehicle;

[0146] Analyze the current motion state of the vehicle based on the magnitude and direction of acceleration.

[0147] In this embodiment, the acceleration sensor can measure the acceleration change of the vehicle on three axes (X-axis, Y-axis and Z-axis), where the X-axis represents the longitudinal direction of the vehicle, that is, the direction from the rear to the front of the vehicle, the Y-axis represents the lateral direction of the vehicle, that is, the direction perpendicular to the direction from the rear to the front of the vehicle, and the Z-axis represents the direction of gravity. The acceleration data may include the magnitude of acceleration and the direction of acceleration. For example, for the longitudinal acceleration of the vehicle, the magnitude of acceleration can represent the intensity of the vehicle's acceleration or deceleration, and the direction of acceleration represents whether the vehicle is accelerating or decelerating.

[0148] By analyzing the acceleration data collected by the acceleration sensor, the current motion state of the vehicle can be inferred based on the acceleration magnitude and acceleration direction. For example, if the acceleration sensor shows that the vehicle has a positive acceleration value in the X-axis direction, the current motion state is that the vehicle is accelerating forward. If the acceleration value changes in the Y-axis direction, the current motion state is that the vehicle is turning or changing lanes.

[0149] In this embodiment, by analyzing the acceleration magnitude and acceleration direction of the vehicle, the current motion state of the vehicle can be accurately determined.

[0150] In some embodiments, the acceleration data includes the lateral acceleration of the vehicle and the longitudinal acceleration of the vehicle; combinations of different lateral acceleration ranges, different lateral acceleration directions, different longitudinal acceleration ranges and different longitudinal acceleration directions correspond to different motion states of the vehicle.

[0151] In this embodiment, by analyzing the lateral and longitudinal acceleration data, the motion state of the vehicle can be inferred, such as acceleration, deceleration, turning, etc. The combination of different lateral acceleration magnitude ranges, different lateral acceleration directions, different longitudinal acceleration magnitude ranges and different longitudinal acceleration directions corresponds to different motion states of the vehicle.

[0152] like Figure 6 As shown, the direction of the longitudinal acceleration of the vehicle is from the rear to the front of the vehicle, the direction pointed by the front of the vehicle is the positive direction, and the direction pointed by the rear of the vehicle is the negative direction. The longitudinal acceleration a greater than zero indicates a positive direction, and less than zero indicates a negative direction. The absolute value of the longitudinal acceleration a indicates the magnitude of the longitudinal acceleration. The direction of the lateral acceleration of the vehicle is perpendicular to the direction from the rear to the front of the vehicle, that is, the direction from the left side to the right side of the vehicle. The direction of the right side of the vehicle is the positive direction, and the direction of the left side is the negative direction. The lateral acceleration f greater than zero indicates a positive direction, and less than zero indicates a negative direction. The absolute value of the lateral acceleration f indicates the magnitude of the lateral acceleration.

[0153] In one example, the vehicle motion state is divided as follows: Figure 7As shown in Figure 1, in order to avoid system misjudgment due to acceleration fluctuations during uniform straight driving, the lateral acceleration thresholds f1 and f2 and the longitudinal acceleration thresholds a1 and a2 are set respectively, where f1<0, f2>0, a1<0, a2>0. The motion state can be divided into 7 states, and the current motion state of the vehicle can be determined according to the range of the lateral acceleration f and the longitudinal acceleration a, as shown in Table 1.

[0154] Table 1

[0155] Movement status Vehicle Movement Lateral acceleration f Longitudinal acceleration a State 1 Go straight at a constant speed <![CDATA[f1≤f≤f2]]> <![CDATA[a1≤a≤a2]]> State 2 Speed ​​up and turn left <![CDATA[f<f1]]> a≥0 State 3 Speed ​​up and go straight <![CDATA[f1≤f≤f2]]> <h2 style=";text-align:left;direction:ltr"><![CDATA[a>a2]]><h2 style=";text-align:left;direction:ltr"> State 4 Accelerate right turn <![CDATA[f2<f]]> a≥0 State 5 Slow down and turn left <![CDATA[f<f1]]> a<0 State 6 Slow down and go straight <![CDATA[f1≤f≤f2]]> <![CDATA[a<a1]]> Status 7 Slow down and turn right <![CDATA[f2<f]]> a<0

[0156] In this embodiment, the vehicle motion state can be divided into more detailed divisions by changing the number and size of the above acceleration thresholds, such as Figure 8 As shown, by setting lateral acceleration thresholds f1, f2, f3, f4 and longitudinal acceleration thresholds a1, a2, a3, a4, the motion state can be divided into 25 states. The embodiment of the present application does not limit the division of the vehicle motion state.

[0157] In this embodiment, by comprehensively analyzing the lateral acceleration and longitudinal acceleration data of the vehicle, the lateral acceleration data reflects the lateral force of the vehicle when turning, while the longitudinal acceleration data indicates the acceleration or deceleration of the vehicle when driving in a straight line. By carefully analyzing the size and direction of these two accelerations, the various motion states of the vehicle can be accurately identified, thereby realizing intelligent control of the blowing system to reduce the discomfort of passengers caused by the movement of the vehicle.

[0158] In some embodiments, different blowing modes correspond to different blowing parameters; the blowing parameters include blowing speed and blowing direction; the blowing speed is adapted to the longitudinal acceleration of the vehicle, and the blowing direction is adapted to the lateral acceleration of the vehicle.

[0159] In this embodiment, the blowing port of the blowing system can blow air toward the driver and passenger sitting on the seat, and the blowing direction can be adapted to the lateral acceleration of the vehicle, that is, the blowing direction changes according to the lateral acceleration of the vehicle, and the change in the blowing direction can be a change in the angle of blowing toward the driver and passenger. In specific settings, since the position of the seat is relatively fixed, the position of the driver and passenger can be determined according to the position of the seat, and by adjusting the blowing direction, the angle of blowing toward the driver and passenger can be adjusted.

[0160] In this embodiment, the blowing speed is adapted to the longitudinal acceleration of the vehicle, that is, the blowing speed changes according to the longitudinal acceleration of the vehicle. For example, the blowing speed can be set to multiple gears, and different gears correspond to different longitudinal acceleration ranges. The wind speed can also be adjusted in the form of pulses, such as Fig. 9As shown; the wind speed can also be adjusted in the form of a sine wave, such as Fig.10 As shown, if the wind speed is adjusted in the form of pulses or sine waves, the frequency of the pulses or sine waves changes according to the longitudinal acceleration of the vehicle.

[0161] In this embodiment, by comprehensively analyzing the longitudinal acceleration and lateral acceleration of the vehicle, it is possible to accurately identify different motion states of the vehicle, such as steady driving, acceleration, deceleration or turning. The blowing speed is adapted to the longitudinal acceleration of the vehicle, so that when the vehicle accelerates or decelerates, the blowing speed can be adjusted to match the movement changes of the vehicle to maintain the comfort of the driver and passengers. For example, during rapid acceleration or deceleration, increasing the blowing speed may help stabilize the passengers' feelings and reduce motion sickness. The blowing direction is adapted to the lateral acceleration of the vehicle, so that when the vehicle turns, the blowing direction is adjusted to help the driver and passengers maintain a sense of balance and reduce the discomfort caused by turning, thereby further reducing the possibility of motion sickness of the driver and passengers and improving the comfort of the driver and passengers.

[0162] In some embodiments, the blowing direction of the blowing system is adjusted by controlling the start and stop of different blowing outlets; or, the blowing direction of the blowing system is adjusted by controlling the air outlet angles of the blowing outlets.

[0163] In this embodiment, according to the setting and layout of the blowing outlets, the blowing direction can be adjusted by controlling the start and stop of different blowing outlets, or by controlling the air outlet angle of the blowing outlets to adjust the blowing direction, thereby achieving flexible adjustment of the blowing direction.

[0164] In some embodiments, before controlling the blowing system to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state in the air outlet mode, the method includes:

[0165] Obtaining the corresponding relationship between the vehicle's motion state and the blowing mode in the wind outlet mode;

[0166] The blowing mode corresponding to the current motion state is matched from the corresponding relationship.

[0167] In this embodiment, the air outlet mode, motion state and blowing method can be pre-stored in association in a database. For example, the air outlet mode, motion state and blowing method can be stored in association through a database table, and the corresponding air outlet mode, motion state and blowing method are stored in the same row of the database table. Different database tables can also be established for different air outlet modes, and the same row of the database table stores the corresponding motion state and blowing method.

[0168] In one example, if the air outlet mode is the first air outlet mode, when the vehicle is in motion state 1, the corresponding air blowing mode is a wind speed of V1, and the angle of the air blowing direction is an angle θ1. When the vehicle is in motion state 1, the corresponding air blowing mode is a wind speed of V1, and the angle of the air blowing direction is an angle θ2.

[0169] After the air outlet mode and the motion state of the vehicle are determined, the corresponding blowing mode can be matched according to the pre-established corresponding relationship.

[0170] In this embodiment, by obtaining the correspondence between the vehicle's motion state and the blowing method in the wind outlet mode, and matching the blowing method in the current motion state from these correspondences, the blowing method can be adjusted in time when the vehicle's motion state changes, thereby improving the adjustment efficiency of the blowing method.

[0171] In some embodiments, when the current motion state is straight-ahead movement at a constant speed, the blowing mode is no blowing;

[0172] When the current motion state is not straight-ahead movement at a constant speed, the blowing direction of the blowing method is adapted to the lateral acceleration of the vehicle.

[0173] In this embodiment, by choosing not to blow air when the vehicle is moving straight at a constant speed, unnecessary air flow interference can be reduced, energy consumption can be reduced, and the discomfort caused by long-term blowing of air to the driver and passengers can be reduced. When the vehicle is not moving straight at a constant speed, the blowing direction is adjusted according to the lateral acceleration of the vehicle to adapt to the vehicle's turning or lane changing operations, which helps to reduce the swaying feeling of passengers caused by the change of the lateral acceleration of the vehicle, and can provide passengers with an additional "sense of support" when the vehicle turns, helping the driver and passengers to maintain balance, thereby reducing the risk of motion sickness.

[0174] In some embodiments, when the air outlet mode is the first air outlet mode, the front air outlet is opened to blow air toward the face of the driver and passenger, and the blowing direction of the blowing mode is toward the face of the driver and passenger and the blowing angle is adapted to the lateral acceleration of the vehicle.

[0175] In this embodiment, if the air outlet mode is the first air outlet mode, the front air outlet can be opened and the rear air outlet can be closed to blow air toward the face of the driver and the passenger.

[0176] Taking the classification of vehicle motion states in Table 1 as an example, the blowing mode in the first air outlet mode is as follows: Fig.11 shown.

[0177] State 1: The vehicle is moving straight ahead at a constant speed, and no air is discharged at this time;

[0178] State 2: The vehicle accelerates and turns left, the left front air outlet is opened, the wind speed is V1, the angle of the blowing direction is angle θ1, and the corresponding blowing range is the left side of the driver's face;

[0179] State 3: The vehicle accelerates and moves straight ahead, the air outlet in front is open, the wind speed is V1, the angle of the blowing direction is angle θ2, and the corresponding blowing range is the forehead and face of the driver and passengers;

[0180] State 4: The vehicle accelerates and turns right, the right front air outlet is opened, the wind speed is V1, the angle of the blowing direction is angle θ3, and the corresponding blowing range is the right side of the driver's face;

[0181] State 5: The vehicle slows down and turns left, the left front air outlet is opened, the wind speed is V2, the angle of the blowing direction is angle θ1, and the corresponding blowing range is the left side of the driver's face;

[0182] State 6: The vehicle decelerates and moves straight ahead, the air outlet in front is open, the wind speed is V2, the angle of the blowing direction is angle θ2, and the corresponding blowing range is the forehead and face of the driver and passengers;

[0183] State 7: The vehicle decelerates and turns right, the right front air outlet is opened, the wind speed is V2, the angle of the blowing direction is angle θ3, and the corresponding blowing range is the right side of the driver's face.

[0184] In this embodiment, by opening the front air outlet in the first air outlet mode and blowing air towards the driver and passenger's face, the blowing angle towards the driver and passenger's face is adapted to the lateral acceleration of the vehicle, which can simulate the wind direction during human movement, help reduce the swaying feeling of passengers caused by changes in the lateral acceleration of the vehicle, thereby reducing the possibility of motion sickness of the driver and passenger and improving the comfort of the driver and passenger.

[0185] In some embodiments, when the air outlet mode is the second air outlet mode, the front air outlet is opened to blow air towards the face of the driver and the rear air outlet is opened to blow air towards the neck of the driver and the passenger; the blowing direction of the blowing method, the blowing angle towards the face of the driver and the blowing angle towards the neck of the driver and the passenger are adapted to the lateral acceleration of the vehicle.

[0186] In this embodiment, if the air outlet mode is the second air outlet mode, the front air outlet can be opened to blow air toward the face of the driver and the rear air outlet can be opened to blow air toward the neck of the driver and the passenger.

[0187] In some embodiments, when the air outlet mode is the second air outlet mode, if the movement state of the vehicle includes vehicle acceleration, the front air outlet is opened to blow air toward the face of the driver and passenger; if the movement state of the vehicle includes vehicle deceleration, the rear air outlet is opened to blow air toward the neck of the driver and passenger.

[0188] Taking the classification of vehicle motion states in Table 1 as an example, the blowing mode in the first air outlet mode is as follows: Fig.12 shown.

[0189] State 1: The vehicle is moving straight ahead at a constant speed, and no air is discharged at this time;

[0190] State 2: The vehicle accelerates and turns left, the left front air outlet is opened, the wind speed is V1, the angle of the blowing direction is angle θ1, and the corresponding blowing range is the left side of the driver's face.

[0191] State 3: The vehicle accelerates and moves straight ahead, the air outlet directly in front is opened, the wind speed is V1, the angle of the blowing direction is angle θ2, and the corresponding blowing range is the forehead and face of the driver and passengers.

[0192] State 4: The vehicle accelerates and turns right, the right front air outlet is opened, the wind speed is V1, the angle of the blowing direction is angle θ3, and the corresponding blowing range is the right side of the driver's face.

[0193] State 5: The vehicle slows down and turns left, the left rear air outlet is opened, the wind speed is V1, the angle of the blowing direction is angle θ4, and the corresponding blowing range is the left rear of the driver's neck.

[0194] State 6: The vehicle decelerates and moves straight, the rear air outlet is opened, the wind speed is V1, the angle of the blowing direction is θ5, and the corresponding blowing range is directly behind the driver's neck.

[0195] State 7: The vehicle decelerates and turns right, the right rear air outlet is opened, the wind speed is V1, the angle of the blowing direction is angle θ6, and the corresponding blowing range is the right rear of the driver's neck.

[0196] Fig.12 As shown, the blowing direction of the blowing system is adjusted by controlling the start and stop of different blowing outlets. In some embodiments, the blowing direction of the blowing system can also be adjusted by controlling the air outlet angle of the blowing outlet, such as Fig.13 shown.

[0197] In some embodiments, when the air outlet mode is the second air outlet mode, the rear air outlet can be closed when the front air outlet is open, and the front air outlet can be closed when the rear air outlet is open, or both the front air outlet and the rear air outlet can be opened at the same time. Fig.14 As shown, the front and rear air outlets can be opened at the same time, and the blowing angles of the blowing directions are adapted to the lateral acceleration of the vehicle. For example, in state 2: the vehicle accelerates to turn left, the left front air outlet is opened, the wind speed is V1, the blowing direction angle is angle θ1, and the corresponding blowing range is the left side of the driver's face. At the same time, the left rear air outlet is opened, the wind speed is V2, the blowing direction angle is angle θ4, and the corresponding blowing range is the left rear of the driver's neck.

[0198] In this embodiment, by deciding to open the front or rear air outlet according to the acceleration or deceleration of the vehicle in the second air outlet mode, and blowing air toward the face or neck in a targeted manner, the wind direction during human movement can be simulated more carefully, which helps the brain integrate information from the visual, vestibular and human sensory systems, reduce the dizziness of the driver and passengers caused by the movement of the vehicle, thereby reducing the possibility of motion sickness and improving the comfort of the driver and passengers.

[0199] In this embodiment, by opening the front air outlet to blow air directly toward the driver and passenger's face and opening the rear air outlet to blow air toward the driver and passenger's neck in the second air outlet mode, the wind direction during human movement can be simulated more carefully. The blowing angles toward the driver and passenger's face and the blowing angles toward the driver and passenger's neck are adapted to the lateral acceleration of the vehicle, which helps to reduce the swaying feeling of the passengers caused by the change in the lateral acceleration of the vehicle, thereby reducing the possibility of motion sickness of the driver and passenger and improving the comfort of the driver and passenger.

[0200] The following describes the control method of the blowing system in the embodiment of the present application in combination with a scenario example. Fig.15 In this scenario example, the sensor can be used to determine whether there is a person sitting in the seat of the vehicle. If it is determined that there is a person sitting in the seat, the blowing function is turned on.

[0201] In this scenario example, after the blowing function is turned on, the sensor can be used to determine whether the driver and passengers will block the rear air outlet. If it is determined that the rear air outlet is blocked, a prompt sound can be issued through a buzzer or microphone to remind the driver and passengers that there is a blockage. After a first preset time, such as 60 seconds, the sensor is used again to determine whether the driver and passengers will block the rear air outlet. If the blockage is not removed, the front air outlet mode (first air outlet mode) is adopted. The acceleration information is monitored in real time according to the acceleration sensor, and the preset state of the vehicle is determined according to the acceleration. The blowing method corresponding to the preset state in the front air outlet mode is executed. During the blowing process, the sensor can be used to determine whether the driver and passengers will block the rear air outlet every second preset time, and the air outlet mode is adjusted according to the judgment result.

[0202] If it is determined that there is no obstruction, or the obstruction is removed within the first preset time, the front and rear dual exhaust air flow mode (second air flow mode) can be used. The acceleration information is monitored in real time according to the acceleration sensor, and the preset state of the vehicle is determined according to the acceleration. The blowing method corresponding to the preset state in the front and rear dual exhaust air flow mode is executed. During the blowing process, the sensor can be used to determine whether the driver and passengers will block the rear air outlet at every second preset time, and the air flow mode can be adjusted according to the judgment result.

[0203] The control method of the hair-drying system provided in the embodiment of the present application can be executed by a control device of the hair-drying system. In the embodiment of the present application, the control device of the hair-drying system executing the control method of the hair-drying system is taken as an example to illustrate the control device of the hair-drying system provided in the embodiment of the present application.

[0208] The control module 1630 is used to control the blowing system to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state in the air outlet mode.

[0209] According to the control device of the blowing system of the present application, the blowing mode of the blowing system is determined according to the blocking condition of the target air outlet; wherein, at least part of the air outlets used for blowing in different air outlet modes are different; the current motion state of the vehicle is analyzed according to the acceleration data of the vehicle; and the blowing system is controlled to blow air to the driver and passengers according to the blowing mode corresponding to the current motion state under the blowing mode. The embodiment of the present application can simulate the wind direction of the human body movement process by controlling the blowing system to blow air to the driver and passengers during the driving of the vehicle, which helps the brain integrate the information of the visual, vestibular and human sensory systems, and reduce the dizziness of the driver and passengers caused by the movement of the vehicle. The blowing mode is flexibly selected according to the blocking condition of the target air outlet and the blowing mode is adjusted according to the current motion state of the vehicle, which can improve the blowing efficiency and more realistically simulate the wind direction of the human body movement process, thereby reducing the possibility of motion sickness of the driver and passengers and improving the comfort of the driver and passengers.

[0210] The control device of the hair drying system in the embodiment of the present application can be an electronic device, or a component in the electronic device, such as an integrated circuit or a chip. The electronic device can be a terminal, or other devices other than a terminal.
