For the purposes of brevity and explanation, the principles of the present invention are described herein with reference primarily to exemplary embodiments thereof. However, those skilled in the art will readily recognize that the same principles are equally applicable to all types of onboard fragrance apparatuses, onboard fragrance systems, and control methods thereof, and that these same principles may be implemented therein, as well as any such variations, without departing from the true spirit and scope of the present patent application. Moreover, in the following description, reference is made to the accompanying drawings that illustrate certain exemplary embodiments. Electrical, mechanical, logical, and structural changes may be made to these embodiments without departing from the spirit and scope of the invention. In addition, while a feature of the invention may have been disclosed with respect to only one of several implementations/embodiments, such feature may be combined with one or more other features of the other implementations/embodiments as may be desired and/or advantageous for any given or identified function. The following description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.
Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.
FIG. 1 is a block diagram of a vehicle fragrance system according to an embodiment of the present invention; fig. 2 is a schematic block diagram of a vehicle-mounted fragrance apparatus according to an embodiment of the present invention. In the following, a fragrance controller 410, a vehicle-mounted fragrance apparatus 400, and a vehicle-mounted fragrance system 10 using the vehicle-mounted fragrance apparatus 400 according to an embodiment of the present invention will be described with reference to fig. 1 and 2.
As shown in fig. 1 and 2, the vehicle-mounted fragrance apparatus 400 may be installed at a predetermined position in the cabin of the vehicle, and the vehicle-mounted fragrance apparatus 400 may be implemented in a terminal form independently from other components of the vehicle-mounted fragrance system 10, for example, may be very conveniently detached from the vehicle-mounted fragrance system 10 or from the vehicle.
The vehicle-mounted fragrance system 10 includes one or more vehicle-mounted fragrance apparatuses 400 according to embodiments of the present invention, and the vehicle-mounted fragrance apparatuses 400 can be used as terminals for emitting various smells. The vehicle-mounted fragrance system 10 further comprises a fatigue detection device 100, wherein the fatigue detection device 100 is used for detecting and obtaining fatigue state information of a user, the user is taken as an example of a driver, the fatigue detection device 100 can be a fatigue driving detection device, the fatigue detection device 100 can be realized by the fatigue detection device 100 already installed on the vehicle, and the corresponding fatigue detection device 100 can also be newly installed on the vehicle for realizing the vehicle-mounted fragrance system 10 of the embodiment of the invention. To improve driving safety, the fatigue detection apparatus 100 is further configured to start detecting the fatigue state of the driver user in real time and obtain corresponding fatigue state information when the vehicle speed is greater than or equal to a predetermined value (e.g., 40 km/h-60 km/h).
In one embodiment, the fatigue detection apparatus 100 determines the fatigue state of the driver, and even specifically determines the current fatigue level of the driver, by collecting and analyzing steering wheel angle data of the running vehicle. Specifically, the fatigue detection apparatus 100 may collect a steering wheel angle value from a steering angle sensor or an EPS system, may calculate a steering angle speed V in real time based on the steering wheel angle value, monitors a change in the steering angle speed with respect to time t, and may determine the fatigue state of the driver.
Fig. 3 illustrates the principle of monitoring the fatigue state of a driver in an embodiment. As shown in fig. 3, the ordinate represents the angular velocity V, the abscissa represents t, and the change of the angular velocity V with respect to time t is shown as a curve 190 in fig. 3.
The applicant has found that the fatigue state of the driver is manifested to some extent in the action of the driver in operating the steering wheel. Illustratively, when a driver is awake, the steering wheel angle is continuously and slowly adjusted, and the steering wheel is finely controlled continuously, so that the vehicle is ensured to run in the middle of the road; when the driver drives in a fatigue state, the steering wheel is hardly operated for a certain time, and then a violent operation is suddenly performed, which is a subconscious operation, and a natural operation does not mean an operation with a large amplitude but a rapid operation. This behavior during driving in a fatigue state can be reflected by the curve 190 shown in FIG. 3; as shown in fig. 3, in phase 1, the steering angle speed is maintained at a nearly constant value (meaning that the steering wheel is hardly rotated) for a certain time, which is represented by a small speed at a steering angle speed around 0 for a certain time (including a time period from t1 to t 2); in phase 2, for the overshoot correction of the steering wheel angle, which occurs when the steering wheel angular velocity rapidly exceeds the minimum reflection amplitude Vmin, a violent operation of a large magnitude occurs in the steering wheel, wherein the angular velocity V has a maximum value Vmax.
The fatigue detection apparatus 100 can determine whether the above phase 1 and phase 2 occur by the following principle.
When the angular velocity V enters a very small value, for example, a small tolerance band, from a large value, and stabilizes for a certain time and the time length exceeds a set value (for example, a predetermined time period t1 to t 2), it can be determined that the driver has occurred in the above phase 1 and entered phase 1; in phase 1, the angular velocity is around 0 and is small for a certain time.
After t2, further detecting an overshoot operation of the steering wheel rotation speed, for example, detecting that the steering wheel rotation speed exceeds the predetermined minimum reflection amplitude Vmin at a time point t3 and falls back after reaching Vmax at a subsequent time point, it can be determined that the driver has occurred in the above phase 2 and entered phase 2. In this phase 2, an overshoot operation event occurs.
After both the above stage 1 and stage 2 are determined, it may be determined that the driver has performed, for example, a fatigue driving operation, and the fatigue detection apparatus 100 may count the number of overshoot operation events of the stage 2 to determine the fatigue degree information of the driver, and for example, it may be determined whether the fatigue degree of the driver is deepened the greater the number of overshoot operation events occurring within a predetermined period of time.
In an embodiment, the fatigue state information obtained by the fatigue detection apparatus 100 includes fatigue degree information, which can be quantitatively represented by the fatigue values exemplified in the following table, and the fatigue state corresponding to each fatigue value is described in table 1.
TABLE 1
| Fatigue value | Description of fatigue State |
| 1 | Very clear-headed |
| 2 | Moderate arousal |
| 3 | Comparative sobering |
| 4 | Neither waking nor sleepy |
| 5 | Slight sleepiness |
| 6 | Sleepiness, staying awake without great effort |
| 7 | Sleepiness, requiring effort to remain awake |
| 8 | Very sleepy, requiring a lot of effort to remain awake |
| 9 | Extremely sleepy and unable to remain awake |
It should be noted that the fatigue detection apparatus 100 is not limited to detecting the fatigue state information by the above exemplary manner, and in other embodiments, the fatigue state information may be determined by one or more of the following manners: (1) monitoring a road maintenance condition of the vehicle through a camera on the vehicle; (2) eye or facial feature information acquired by an image sensor; (3) physiological characteristic information obtained by other physiological sensors (e.g., smart wearable devices). Of course, the detection of fatigue state information may also be implemented in a manner exemplified in connection with fig. 3 above.
Continuing with fig. 1, in one embodiment, where the vehicle-mounted fragrance apparatus 400 is used in conjunction with a vehicle-mounted air conditioning apparatus of a vehicle, the vehicle-mounted fragrance system 10 may transmit the detected fatigue status information to a central controller (e.g., CGW or audio central controller, etc.) 200 of the vehicle, and the central controller 200 may issue an instruction to activate the fragrance function and even an instruction about the concentration of the refreshing smell according to the fatigue status information. These instructions pertain to instructions generated based on fatigue status information, it being understood that these instructions may be implemented on different components, for example, even in air conditioner controller 300 or in vehicle-mounted fragrance apparatus 400.
In one embodiment, a fatigue automatic reminding function key (not shown) may be provided in the vehicle-mounted fragrance system 10, so as to control whether to send the fatigue state information or the generated instruction thereof to the air conditioner controller 300 and/or the vehicle-mounted fragrance apparatus 400; the user may operate the fatigue automatic alert function key to determine whether to trigger the function of emitting a refreshing smell of the vehicle-mounted fragrance apparatus 400.
Continuing with fig. 2, the vehicle-mounted fragrance apparatus 400 is provided with a fragrance controller 410, and the fragrance controller 410 controls the emission of a refreshing scent based on the received fatigue state information or controls the emission of a refreshing scent based on an instruction generated by the fatigue state information. It should be noted that, if the fragrance controller 410 directly receives the fatigue state information, such as a fatigue value indicating the fatigue degree information, the fragrance controller 410 may analyze and process the fatigue state information, so as to generate a corresponding instruction to perform an operation of controlling the emission of the refreshing smell; if the fragrance controller 410 directly receives the instruction generated based on the fatigue status information, the process of analyzing the fatigue status information and generating the instruction may be performed outside the fragrance controller 410, for example, in the central controller 200 of the vehicle-mounted fragrance system 10. The fragrance controller 410 may be specifically realized by, for example, an MCU or the like.
As further shown in fig. 2, the vehicle-mounted fragrance apparatus 400 includes a receiving component (not shown in the figure) for receiving the fatigue state information or the instruction generated based on the fatigue state information, and the receiving component may be, for example, a LIN transceiver, which may be provided independently from the fragrance controller 410, or may be implemented by a receiving portion in the fragrance controller 410.
As further shown in fig. 2, the vehicle-mounted fragrance apparatus 400 includes a fragrance emission unit 450 for emitting a refreshing smell; fragrance emitting unit 450 may, for example, use one or more fragrance cartridges, each of which may provide a respective scent; the fragrance emitting unit 450 may be coupled with the fragrance controller 410, and may implement emission processes of different refreshing smells and/or different smell concentration levels based on the control of the fragrance controller 410. In one embodiment, the vehicle-mounted fragrance apparatus 400 may emit a plurality of smells, which are not limited to refreshing smells, for example, and also have regular fragrance smells, and thus, the corresponding vehicle-mounted fragrance apparatus 400 may have a plurality of fragrance boxes to enhance different fragrances, wherein the specific type of fragrance used for refreshing is not limiting.
The vehicle-mounted fragrance apparatus 400 performs a selection operation based on the received fatigue state information or the instruction in a case where it is determined that the emission of the refreshing smell is required, and specifically, the vehicle-mounted fragrance apparatus 400 is provided with, for example, a stepping motor 430 and a fragrance type detection 440, which may be provided corresponding to the fragrance emission unit 450; the fragrance type detection 440 may detect a currently emitted fragrance type of the vehicle-mounted fragrance apparatus 400, which may be implemented by a fragrance resistor, for example, and may detect the currently emitted fragrance type according to a detected resistance value, so that the fragrance controller 410 may know the currently used fragrance type; the stepping motor 430 may perform an operation of selecting a type of fragrance under the control of the fragrance controller 410, and the stepping motor 430 may select a scent box for refreshing a scent, for example, according to an instruction output from the fragrance controller 410.
Continuing with FIG. 2, in-vehicle fragrance apparatus 400 also includes a fan 420, which may be positioned in correspondence with fragrance emitting unit 450; the fan 420 is used for blowing air to the selected fragrance to volatilize the corresponding scent, and the motor of the fan 420 can receive an instruction from the fragrance controller 410, so that the operation speed of the fan 420 can be controlled, and the concentration of the refreshing scent can be controlled.
In one embodiment, the fragrance controller 410 controls the amount of concentration of the refreshing scent emitted according to the fatigue degree information. For example, as shown in correspondence table one, when the fatigue values are 1 and 2, the stepping motor 430 is controlled not to select the refreshing fragrance; controlling the stepping motor 430 to select the refreshing fragrance and controlling the fan 420 to emit a refreshing fragrance of a slight concentration at fatigue values of 3 and 4; at fatigue values of 5 and 6, controlling the stepping motor 430 to select a refreshing fragrance and controlling the fan 420 to emit a refreshing fragrance of a medium concentration; at fatigue values of 7, 8 and 9, the stepping motor 430 is controlled to select the refreshing fragrance and the fan 420 is controlled to emit the refreshing fragrance of the maximum concentration.
When the received current fatigue level information is changed to be lower than a predetermined level, for example, after the fatigue value of the driver is recovered to the fatigue value of 1 or 2 and maintained for a predetermined time, the fragrance controller 410 basically stops emitting the refreshing fragrance by controlling the stepping motor 430, and may exit the refreshing fragrance automatic activation operating state, that is, may be automatically turned off after the fatigue of the driver is removed.
It should be noted that the state information of the fragrance controller 410 may be fed back to the fragrance control system 10 via a LIN transceiver, for example.
It will be understood that the vehicle-mounted fragrance device 400 and the vehicle-mounted fragrance system 10 of the above embodiments can actively emit refreshing taste when detecting that the driver is in a fatigue state, so that the driver fatigue can be timely eliminated, the driving safety hidden danger is reduced, the driving safety is improved, and the experience of users (especially drivers) in the vehicle is greatly improved.

This step may be performed by the fatigue detecting apparatus 100 shown in fig. 1, and the specific detection principle thereof is described in the above-mentioned example explanation about the fatigue detecting apparatus 100, for example, in an embodiment, the fatigue state information of the driver is determined according to the change of the turning angle speed of the steering wheel operated by the driver with respect to time.
In step S520, the fatigue state information or the command generated based on the fatigue state information is obtained. This step may be accomplished by vehicle fragrance apparatus 400. The fatigue state information may contain information on the degree of fatigue such as a fatigue value.
