Detailed Description

Referring to fig. 1, the environmental conditioning system 10 may be disposed in a vehicle, and includes a sensing module 12, a determining module 14, a control module 16, and a controlled module 18. The sensing module 12 is configured to detect at least one environmental parameter EP related to air inside the vehicle, where the environmental parameter EP may be at least one of carbon dioxide concentration, carbon monoxide concentration, oxygen concentration, anion concentration, air temperature/temperature, and humidity of the air inside the vehicle, and the sensing module 12 generates in-vehicle information related to the state of the air inside the vehicle or a driver inside the vehicle. The determining module 14 is coupled to the sensing module 12 for determining an environmental sleepiness index EI corresponding to an environment in the vehicle or a fatigue level DL of the driver according to the vehicle interior information. The control module 16 is coupled to the determination module 14, and the control module 16 is configured to generate a control signal CTRL according to the ambient lethargy index EI or the fatigue level DL to control the controlled module 18 to adjust at least one sensed environmental parameter PMT (related to the air inside the vehicle) such that the at least one environmental parameter EP (related to the air inside the vehicle) is outside a comfort critical range CFZ and the driver is kept awake.

The comfort critical zone CFZ may be a region formed by the Temperature, humidity or Wet Bulb Temperature (Wet Bulb) in the vehicle in a specific range, wherein the humidity may be the absolute humidity (g/m) in the air³Mass of water vapor contained in the air), humidity value or relative humidity (%, ratio between absolute humidity and maximum humidity), or moisture content (gm/kg, mass of water vapor in dry air in unit kg), etc. as a measurement basis. The comfort critical range CFZ may be set or adjusted according to actual conditions such as season, climate, weather, area of the vehicle, user's habit, etc. For example, referring to table I, an embodiment of a comfort level classification table is shown in table I, which lists temperature and humidity ranges corresponding to the comfort critical ranges CFZ during different seasons, wherein the comfort critical ranges CFZ may be air temperatures during autumn and winter19-21 ℃ and a humidity value of 52-58%; in spring and summer, the comfort critical range CFZ can be between 24 and 26 degrees in air temperature and between 52 and 58 percent in humidity.

TABLE I comfort grade graduation Table

Referring to fig. 2, the sensing module 12 may include an environmental sensor 120 and a Camera 122, wherein the Camera 122 may be a dedicated Camera (DMC) for Monitoring the Driver. The sensing module 12 can sense the environmental parameter EP by using the environmental sensor 120 and transmit the environmental parameter EP to the determining module 14 (or the control module 16, in which the in-vehicle information may include the environmental parameter EP), the determining module 14 can determine and generate the environmental sleepiness index EI according to the environmental parameter EP sensed by the sensing module 12, in one embodiment, the environmental sleepiness index EI can be related to or simply be a carbon dioxide concentration or a carbon monoxide concentration in the vehicle, and the environmental sleepiness index EI generated by the determining module 14 is higher when the carbon dioxide (or carbon monoxide) concentration is higher. In addition, the sensing module 12 can also transmit the environmental parameter EP to the control module 16, and the control module 16 can determine whether the environmental parameter EP belongs to the comfort critical range CFZ.

In addition, the sensing module 12 can capture the face of the driver by using the camera 122, and generate a face frame information FC corresponding to the driver to the determining module 14 (in this case, the in-vehicle information may include the face frame information FC). The determining module 14 can perform image recognition operation on the facial frame information FC to generate an image recognition result IRS, and determine the fatigue level DL of the driver according to the image recognition result IRS. In one embodiment, the image recognition result IRS may be at least one of a blinking frequency, a nodding frequency, or a duration of a closed eye of the driver. In one embodiment, the fatigue level DL may represent no fatigue (e.g., DL ═ 0), light fatigue (e.g., DL ═ 1), medium fatigue (e.g., DL ═ 2), heavy fatigue (e.g., DL ═ 3), or very heavy fatigue (e.g., DL ═ 4). When the driver starts blinking, nodding or closing, which means that the driver is about to or about to start dozing, the determining module 14 may generate the fatigue level DL corresponding to light fatigue (for example, DL is 1), and as the blinking frequency, nodding frequency or closing time length of the driver increases, which means that the driver gradually becomes dozing, the determining module 14 may generate the fatigue level DL corresponding to moderate fatigue (DL is 2), severe fatigue (DL is 3) or very severe fatigue (DL is 4).

The control module 16 generates a control signal CTRL to the controlled module 18 according to the ambient lethargy index EI or the fatigue level DL, so as to adjust the somatosensory environmental parameter PMT, such that the environmental parameter EP can be far away from the comfort critical range CFZ. When the control module 16 determines that the environmental parameter EP belongs to the comfort critical range CFZ and the fatigue degree DL is greater than a specific degree (or the environmental lethargy index EI is greater than a specific value), or when the fatigue degree DL is greater than the specific degree (or the environmental lethargy index EI is greater than the specific value), the control module 16 may generate the control signal CTRL to adjust the somatosensory environmental parameter PMT sensed by the driver, where the somatosensory environmental parameter PMT sensed by the driver may be air temperature, humidity, negative ion concentration, or the like, so that the environmental parameter EP in the vehicle is far from the comfort critical range CFZ. In one embodiment, the controlled module 18 may be an Air Conditioner (AC) in a vehicle, and the driver may feel the sensible environment parameter PMT as Air temperature/temperature. When the control module 16 determines that the environmental parameter EP belongs to the comfort critical range CFZ or the fatigue level DL is greater than a specific level (or the environmental lethargy index EI is greater than a specific value), the control module 16 may generate a control signal CTRL to control the air conditioning system such that the air temperature/temperature (corresponding to the sensible environmental parameter PMT) sensed by the driver is particularly low (or particularly high), and the driver may be maintained in a waking state. In addition, the control module 16 may generate the control signal CTRL simply according to the environmental parameter EP, and when the control module 16 determines that the environmental parameter EP belongs to the comfort critical range CFZ, the control module 16 may generate the control signal CTRL to adjust the somatosensory environmental parameter PMT sensed by the driver, so that the environmental parameter EP is far away from the comfort critical range CFZ.

Further, the operator or the control module 16 may determine the wake-up threshold WK 1-WKN according to at least one of the area, time, season, or climate where the vehicle is located. Similar to the comfort critical range CFZ, the wake-up critical range WK 1-WKN may also be a plurality of regions formed by the temperature, humidity and even wet bulb temperature inside the vehicle. Referring to fig. 3, the wake-up threshold ranges WK 1-WK 4 are all areas surrounding the comfort threshold range CFZ centered around the comfort threshold range CFZ, wherein the wake-up threshold range WK1 surrounds the comfort threshold range CFZ, the wake-up threshold range WK2 surrounds the wake-up threshold range WK1, the wake-up threshold range WK3 surrounds the wake-up threshold range WK2, and the wake-up threshold range WK4 surrounds the wake-up threshold range WK 3. In addition, the wake threshold WK1 is closest to the comfort threshold CFZ, the wake threshold WK2 is second closest to the comfort threshold CFZ, the wake threshold WK4 is farthest from the comfort threshold CFZ, and the wake threshold WK3 is second farthest from the comfort threshold CFZ. Referring again to Table I, Table I lists ranges of temperature and humidity corresponding to the wake threshold ranges WK 1-WK 4 in one embodiment. For example, in autumn and winter, the temperature of the wake-up critical range WK1 is 17-19 ℃ or 21-23 ℃, the humidity is 46-52% or 58-64%, and so on.

The further the distance between the wake critical range and the comfort critical range CFZ is, the stronger the discomfort (degree of discomfort) experienced by the human body is. In one embodiment, the control module 16 may determine to adjust the environmental parameter EP to one of the wake-up threshold ranges WK 1-WK 4 according to the fatigue level DL (or the environmental lethargy index EI). In one embodiment, the control module 16 may adjust the environmental parameter EP to a wake-up threshold range that is farther from the comfort threshold range CFZ when the fatigue level DL (or the environmental lethargy index EI) is larger. For example, when the fatigue level DL corresponds to light fatigue (DL ═ 1), the control module 16 may adjust the environmental parameter EP to the wake-up threshold range WK 1; when the fatigue level DL corresponds to very severe fatigue (DL ═ 4), the control module 16 may adjust the environment parameter EP to the wake-up threshold range WK4, and so on.

As can be seen from the above description, the environmental conditioning system 10 can utilize the sensing module 12 and the determining module 14 to determine the mental condition of the driver in advance, and when the driver is in a state of mental confusion (e.g. blinking/nodding frequently too high or closed for too long), the control module 16 can generate the control signal CTRL according to the fatigue level DL (or the environmental lethargy index EI) to adjust the somatosensory environmental parameter PMT (e.g. temperature or humidity) sensed by the driver in the vehicle, so that the environmental parameter EP can be far away from the comfort critical range CFZ, and the driver can be kept awake.

With respect to the operation of the environmental conditioning system 10, it can be summarized as a process 40, and the process 40 can be executed by the environmental conditioning system 10, as shown in fig. 4, the process 40 includes the following steps:

step 402: an environmental parameter EP related to the air in the vehicle is detected to generate information in the vehicle.

Step 404: the environmental lethargy index EI of the environment in the vehicle or the fatigue level DL of the driver is determined based on the in-vehicle information.

Step 406: according to the ambient lethargy index EI or the fatigue level DL, a control signal CTRL is generated to adjust at least one perceived ambient parameter PMT related to the driver's perception in the vehicle such that the ambient parameter EP is away from the comfort critical range CFZ.

For details of the operation of the process 40, please refer to the related paragraphs, which are not repeated herein.

It should be noted that the above-mentioned embodiments are provided for illustrating the concept of the present invention, and those skilled in the art can make various modifications without being limited thereto. For example, the environmental regulation system 10 can apply Fuzzy logic control (Fuzzy logic control) to obtain the corresponding relationship between the fatigue level DL (or the environmental lethargy index EI) and the adjustment level (e.g. the wake-up critical range WK 1-WKN) of the body-sensing environmental parameter PMT in the control signal CTRL.

In addition to the air conditioning system, the controlled module 18 may include a seat temperature module, and the control module 16 may generate a control signal CTRL to control the seat temperature module according to the fatigue level DL (or the ambient lethargy index EI) to adjust at least one of the headrest temperature, the seat temperature, or the handle temperature sensed by the driver in the vehicle, where the somatosensory ambient parameter sensed by the driver is one of the PMT headrest temperature, the seat temperature, or the handle temperature. When the control module 16 determines that the fatigue level DL is greater than a specific level (or the environmental lethargy index EI is greater than a specific value), the control module 16 may generate a control signal CTRL to control the seat temperature module such that the headrest temperature, the seat temperature, or the handle temperature (corresponding to the somatosensory environmental parameter PMT) sensed by the driver is particularly low (or particularly high), and the driver may be maintained in the awake state.

In addition, the controlled module 18 may include an audio/video system, and the control module 16 may generate a control signal CTRL to control the controlled module 18 (audio/video system) according to the fatigue level DL (or the environmental lethargy index EI) to adjust the volume heard by the driver in the vehicle or the type of music played, or the light effect seen by the driver in the vehicle, where the somatosensory environmental parameter PMT felt by the driver is one of the volume, the type of music, or the light effect. In one embodiment, when the fatigue level DL is greater than a specific level, the control module 16 can adjust the volume of the audio/video system to be larger, so that the driver can be kept in a more awake state. In an embodiment, when the fatigue level DL is greater than a specific level (or the environmental lethargy index EI is greater than a specific value), the control module 16 can adjust the type of music played by the audio/video system to be music with a definite rhythm, such as rock music, twitch music or heavy metal music, so that the driver can be kept awake.

In addition, the controlled module 18 may include an anion generator, and the control module 16 may generate a control signal CTRL to control the anion generator according to the fatigue level DL (or the environmental lethargy index EI) so as to adjust the anion concentration sensed by the driver in the vehicle, where the somatosensory environmental parameter PMT sensed by the driver is the anion concentration. In one embodiment, when the fatigue level DL is greater than a specific level (or the environmental lethargy index EI is greater than a specific value), the control module 16 may generate the control signal CTRL to control the anion generator to generate more anions to increase the anion concentration in the vehicle, so that the driver can be maintained in a waking state.

In addition, the controlled module 18 may include a power window lifter, and the control module 16 may timely generate the control signal CTRL to control the power window lifter according to the fatigue level DL (or the environmental lethargy index EI), where the somatosensory environmental parameter PMT sensed by the driver may be at least one of temperature, carbon dioxide concentration, or carbon monoxide concentration. When the fatigue level DL is greater than a certain level (or the environmental lethargy index EI is greater than a certain value), the control module 16 may generate a control signal CTRL to open or lower the window, increasing the flow or convection between the air inside the vehicle and the air outside the vehicle (corresponding to changing the temperature, carbon dioxide concentration, or carbon monoxide concentration sensed by the driver inside the vehicle), so that the driver may be maintained in a wakeful state.

In addition, the controlled module 18 may include an odor regulator, perfume or aromatic essential oil (such as essential oil or medicinal oil containing mint component, for example, white flower oil, largeline oil, green oil crystal, etc.) may be contained in the odor regulator, and the control module 16 may timely generate the control signal CTRL to control the odor regulator according to the fatigue level DL (or the environmental lethargy index EI), where the sensory environmental parameter PMT sensed by the driver may be the molecular concentration of the corresponding specific odor molecule in the air. When the fatigue level DL is greater than a certain level (or the environmental lethargy index EI is greater than a certain value), the control module 16 may generate a control signal CTRL to control the odor regulator to adjust the odor in the vehicle such that the driver may be maintained in a more awake state.

In addition, the environmental conditioning system 10 is not limited to actively detect the environmental status or the driver status to adjust the somatosensory environmental parameter away from the comfort critical range, but the environmental conditioning system of the present invention can passively receive the user instruction of the driver or the user to adjust the somatosensory environmental parameter away from the comfort critical range. Referring to FIG. 5, environmental conditioning system 50 includes a human-machine interface 52, control module 16, and controlled module 18. The human-machine interface 52 may include at least one of a button, a touch panel, a voice control module, a gesture sensing module, or an eye control module, for providing a user command for a driver or a user to Manually (Manually) input, the human-machine interface 52 may generate a control command CMD to the control module 16 after receiving the user command, and the control module 16 may generate a control signal CTRL according to the control command CMD to control the controlled module 18, so as to adjust at least one somatosensory environmental parameter PMT associated with the driver in the vehicle, such that the somatosensory environmental parameter PMT is away from the comfort critical range CFZ, and the driver is maintained in an awake state. For the remaining details of the control module 16 and the controlled module 18, please refer to the related paragraphs, which are not repeated herein.

In summary, the environmental conditioning system of the present invention can actively determine the mental state of the driver in advance by using the sensing module and the determining module, and when the driver is in the state of mental disorder, the control module can control the controlled module according to the fatigue degree (or the environmental somnolence index) to adjust the sensible environmental parameter sensed by the driver in the vehicle, so that the environmental parameter or the sensible environmental parameter sensed by the driver is far away from the comfort critical range, and the driver can be maintained in the waking state.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
