And the vehicle-mounted equipment sends the information reminding result to the electronic equipment so as to remind other users of the driving state of the driver.

Fig. 1B is a schematic flow chart of an embodiment of an information reminding method according to an embodiment of the present application. The information reminding method described in the embodiment is applied to the vehicle-mounted equipment, wherein the vehicle-mounted equipment comprises at least one image processing unit, and comprises the following steps of:

101. A set of physiological parameters of a first user is acquired.

The first user may be set by the user or default by the system, which is not limited herein; the first user may be a driver, etc.

The vehicle-mounted equipment can comprise equipment such as a sensor, and the physiological parameter set of the user can be acquired through the sensor.

Wherein, the set of physiological parameters may include a plurality of physiological parameters, and the physiological parameters may include at least one of the following: heart rate, blood pressure, blood temperature, blood lipid content, blood glucose content, thyroxine content, epinephrine content, platelet content, blood oxygen content, brain waves, and the like, are not limited herein.

102. And judging whether the first user is in a fatigue driving state or not according to the physiological parameter set.

The method may further include determining a user driving state of the first user according to a plurality of physiological parameters in the physiological parameter set, where the user driving state may include at least one of: the normal driving state, the safe driving state, the excited driving state, the fatigue driving state, the drunk driving state, and the like are not limited herein; in the present application, only the fatigue driving state is exemplified, and the present application is also applicable to driving states of other users, and is not described herein.

The data processing may be performed on the representation of various parameters in the physiological parameter set (for example, electrocardiogram, blood pressure change chart, brain wave graph, etc.), so as to comprehensively determine whether the first user is in a fatigue driving state.

Optionally, the vehicle-mounted device may include a camera, where the camera may be mounted at a position of a rearview mirror or a steering wheel, and a face image of the user may be obtained by photographing the camera, and whether the user is in a fatigue driving state may be determined by performing image processing on the face image.

In one possible example, if a plurality of physiological parameters are included in the set of physiological parameters; the step of judging whether the target user is in a fatigue driving state according to the physiological parameter set may include the steps of: generating a physiological curve graph corresponding to each physiological parameter in the physiological parameter set according to the physiological parameter set to obtain a plurality of physiological curves; extracting features of the plurality of physiological graphs to obtain a plurality of feature sets, wherein each feature set corresponds to one physiological graph; according to the feature sets, evaluating the physiological parameter set to obtain a target evaluation value; and if the target evaluation value is greater than or equal to a preset threshold value, determining that the first user is in the fatigue driving state.

The physiological graph corresponding to each physiological parameter may be generated according to physiological parameters acquired by the sensor in different time periods or time points, for example, if the physiological parameter is a heart rate, the heart rate corresponding to the user in different time periods in a preset time period may be acquired, and an electrocardiogram (physiological graph) may be generated, where the electrocardiogram may be used to represent the rate of change of the heart rate of the first user in the preset time period.

Wherein, the above feature may refer to a curve change feature corresponding to each physiological curve, and for example, the feature may include at least one of the following: the change point positions, the number of curve convex points, the number of curve concave points, the data average value, the data divergence condition, the time domain characteristics and the like are not limited herein; the time domain features may include autocorrelation coefficients, trend features, etc., where the autocorrelation coefficients may be used to describe the cross-correlation of time sequences in a curve at different time points, and the trend features may refer to the characteristic of the increase or decrease of data over a certain period, such as the increase or decrease of heart rate over a certain period, etc., and are not limited herein.

After the curves in each physiological graph are subjected to data denoising, noise filling, data normalization and the like, the features in each physiological graph are counted to obtain a feature set corresponding to each physiological graph. For example, the average condition of the data, such as the average heart rate over a period of time, etc., may be determined by counting the center position of each curve and by the center position. In the present application, the preset feature may be preset to an abnormal data state, for example, a state that the heart rate is in a decreasing state in the graph during a certain period.

Wherein, the evaluation index can be preset, and the physiological parameter set can be evaluated according to the evaluation index to determine a target evaluation value, and further, the driving state of the first user can be further judged according to the target evaluation value.

The preset threshold value may be set by the user or default by the system, which is not limited herein; in a specific implementation, different preset thresholds can be set according to different driving states of users, so that requirements of different scenes (such as fatigue driving, drunk driving, overspeed driving and the like) can be met, scene transformation can be adapted more, in addition, the preset thresholds can be adjusted dynamically, and the practicability of a scheme is improved.

The terminal device may determine a mapping relationship between a preset user driving state and a preset threshold, and determine a preset threshold corresponding to the fatigue driving state according to the mapping relationship, and then compare the target evaluation value with the preset threshold, and further determine that the first user is in the fatigue driving state if the target evaluation value is greater than or equal to the preset threshold.

In one possible example, the evaluating the physiological parameter set according to the feature sets to obtain the target evaluation value may include the following steps: determining the weight corresponding to each feature in each feature set according to the mapping relation between the preset feature and the preset weight to obtain a plurality of weights corresponding to each feature set; determining the average value of the weights in each feature set to obtain a target weight corresponding to each physiological parameter, and obtaining a plurality of target weights corresponding to the physiological parameters; determining an evaluation coefficient corresponding to each physiological parameter according to a mapping relation between a preset physiological parameter and the evaluation coefficient to obtain a plurality of evaluation coefficients; and carrying out weighting operation on the plurality of target weights and the plurality of evaluation coefficients to obtain a target evaluation value.

The multiple characteristics in the multiple characteristic sets represent the physiological characteristics of the first user in the current user driving state or the current scene, and because the change and fluctuation of each physiological parameter in the human body are different in different user driving states, the target evaluation value of the first user about whether the first user is in the fatigue driving state can be comprehensively evaluated based on the multiple characteristics.

The mapping relation between the preset features and the preset weights in the vehicle-mounted equipment can correspond to different weights aiming at different features, and the larger the weights are, the greater the possibility that the features are judged to be in a fatigue driving state is indicated; the mapping relation between the physiological parameters and the evaluation coefficients can be preset, and when the driving state of the user is judged, the evaluation coefficients can reflect the importance of the physiological parameters corresponding to the driving states of the user, namely the specific gravity of the physiological parameters on the evaluation of the driving states of the user; the larger the evaluation coefficient is, the larger the evaluation influence of the physiological parameter on the evaluation value corresponding to the driving state of the final user is.

For example, in evaluating the user driving state (e.g., fatigue driving state) of the user, the specific gravity of a part of the physiological parameters (e.g., heart rate, blood temperature, epinephrine content, etc.) in the evaluation value evaluation may be appropriately increased.

In a specific implementation, a weight corresponding to each feature in a feature set corresponding to each physiological parameter can be determined according to a preset mapping relationship between the feature and the feature weight, and further, the vehicle-mounted device can obtain a plurality of weights corresponding to each physiological parameter, and as the plurality of weights can represent an evaluation value of each feature for a fatigue driving state, the setting of the weights can be preset by the vehicle-mounted device, and a specific weight can be set by a user or a system per se, so that the vehicle-mounted device is not limited; for the same feature, the sum of weights of features corresponding to all physiological parameters is 1, for example, for the feature of the number of curve pits, the weight of the number of curve pits being a is a, the weight of the number of curve pits being B is B, and so on, the weight of the number of curve pits being N is N, and then a+b+ … +n=1, where A, B, N is a positive integer, and a, B and N are natural numbers.

Optionally, because of different driving states of the user, the features in each physiological graph are different, and the preset weight corresponding to each feature can be adjusted according to different driving states of the user, so as to adapt to more scenes, and be beneficial to improving the evaluation accuracy.

Further, after determining each feature set, that is, a plurality of weights corresponding to each physiological parameter, the target weight corresponding to each physiological parameter may be obtained by calculating a mean value or a mean square error of the plurality of weights in each feature set.

Therefore, in the embodiment of the application, the driving state of the user of the target user can be evaluated through the mapping relation between the preset features and the weights and the mapping relation between the preset physiological parameters and the evaluation coefficients, and the influence of a plurality of features in each physiological parameter and each physiological parameter on the driving state of the user is comprehensively considered, so that the accuracy of determining the driving state of the user is improved.

103. And if the first user is in the fatigue driving state, early warning is carried out on the first user through a first atmosphere lamp corresponding to the first user.

When a first user (for example, a driver) is in a fatigue driving state, if the first user is reminded of being in the fatigue driving state through vibration, the first user is generally reminded of being in the fatigue driving state through fixed regular vibration frequency, after the user adapts to the vibration frequency, the first user is not reminded of being in the vibration state, then, the first user can be warned through an atmosphere lamp, the first user can be kept in a normal driving state through the change of the light of the first atmosphere lamp and the color stimulation, so that the first user is helped to dispel sleepiness, the mental concentration of the first user is improved, and driving safety is improved.

The vehicle-mounted device may be provided with a plurality of atmosphere lamps as shown in fig. 1A, and the first atmosphere lamp may be provided at a position such as a steering wheel, a door frame, an audio device, a seat belt, an instrument panel, a seat, etc., and the specific position is not limited herein; the first atmosphere lamp may be an atmosphere lamp installed in a visual range of the first user.

Optionally, before the early warning is performed on the first user through the first atmosphere lamp corresponding to the first user, the method further includes the following steps: determining a first position corresponding to the first user; determining a target range taking a preset distance as a radius and a first position as a circle center; and determining the atmosphere lamp in the target range as the first atmosphere lamp.

The preset range may be set by the user or default by the system, which is not limited herein; the preset range may refer to a visual range of the user in the driving state.

In a specific implementation, a first position corresponding to the first user can be determined, the first position can refer to the position of eyes or fingers of the first user, the first position is used as a circle center, a visual range of the first user is used as a radius, a target range is determined, and an atmosphere lamp in the target range is formulated as a first atmosphere lamp.

Optionally, when the first user is in the fatigue driving state, the visual range of the first user is changed, and then the eye state of the first user can be monitored through a camera or the like in the vehicle-mounted device, so that the visual range of the first user can be determined in real time.

104. If the second user is determined to exist, determining the position information of the second user, and determining a second atmosphere lamp corresponding to the second user according to the mapping relation between the preset position information and the preset atmosphere lamp, wherein the second atmosphere lamp is used for reminding the second user that the first user is in a fatigue driving state so as to help the second user to remind the first user.

Wherein the second user may refer to a passenger with respect to the first user, and other users than the first user.

The position information of the second user may refer to a position of a passenger or a rear seat, and is not limited herein. The second atmosphere lamp may refer to an atmosphere lamp within a visual range of the second user, and the second atmosphere lamp may include at least one atmosphere lamp as shown in fig. 1A.

The mapping relationship between the preset position information and the preset atmosphere lamp may be determined according to the visual range of the second user, or may be set by default or by the user, which is not limited herein. In a specific implementation, according to a mapping relationship between the preset position information and the preset atmosphere lamp, a second atmosphere lamp corresponding to the second user may be determined, for example, if the user sits on a rear seat, the atmosphere lamp corresponding to the rear seat may be determined to be the atmosphere lamp located at the back of the front seat, or the position of the vehicle handle or the vehicle glass.

Further, since the rear passenger may not observe that the driver (first user) is in the fatigue driving state, the second user may be alerted by the second mood light: the first user is in the fatigue driving state at the moment, if the first user is not reminded by the first atmosphere lamp, the second user can wake up or remind the first user timely, driving safety is improved, and the first user is in favor of ensuring smooth running in a high-speed scene.

Optionally, after the determining the second atmosphere lamp corresponding to the second user, the method may further include the following steps: determining a first rhythm strategy corresponding to the fatigue driving state according to a mapping relation between a preset user driving state and a preset rhythm strategy; and controlling the second atmosphere lamp to perform the rhythm according to the first rhythm strategy, wherein the first rhythm strategy is used for reminding the second user that the first user is in a fatigue driving state.

The preset rhythm policy may be set by the user or default by the system, which is not limited herein; the vehicle-mounted device can preset different rhythm strategies of the atmosphere lamp according to different driving states of the user in advance, so that after the atmosphere lamp flashes or is lighted, the user can acquire information in time, for example: whether overspeed, whether fatigue driving and the like are beneficial to helping the user to adjust driving state in time and to safe driving.

For example, for the fatigue driving state in the present application, the first policy of the second atmosphere lamp may be preset to be: the first user (driver) can be determined to be in a fatigue driving state in a first uniform manner by the second atmosphere lamp by the second user (passenger), wherein the second user can remind the first user after receiving the fatigue driving state of the driver, and the second atmosphere lamp can be turned off after reminding.

Optionally, the method may further include the steps of: determining a first user identity and a second user identity corresponding to the first user and the second user respectively; determining a second rhythm strategy corresponding to the first user identity and a third rhythm strategy corresponding to the second user identity according to a mapping relation between the preset user identity and a preset rhythm strategy; and simultaneously controlling the first atmosphere lamp and the second atmosphere lamp to perform rhythm according to the second rhythm strategy and the third rhythm strategy, so that the first atmosphere lamp and the second atmosphere lamp realize alternate flickering.

Wherein, the user identity may include at least one of the following: drivers, passengers, driver license authorities, etc., are not limited herein; the first user and the second user are different in identity, and one of them is a driver.

For example, in one possible scenario, if the second user identity is a driver license attendant, the driver license attendant may be alerted by a flashing or color changing or a rhythm of the second atmosphere lamp, and the monitored person is in a state of fatigue driving.

The vehicle-mounted device can preset a mapping relation between the user identity and a preset rhythm strategy, the second rhythm strategy and the third rhythm strategy can be the same or different, and the third rhythm strategy is different from the first rhythm strategy, and as the reminding function or the reminding function of atmosphere lamps around different user identities are different, different rhythm strategies can be set for different user identities to distinguish different reminding functions or reminding functions.

For example, in one possible scenario, if the first user is a driver, the second user is a passenger, and the second user is sitting in the co-driving position, the determined first atmosphere lamp may be repeated with the second atmosphere lamp, where the flicker range of the second atmosphere lamp and the first atmosphere lamp is in the cross line of sight range of the first user and the second user, as shown in fig. 1C, which is a schematic scenario of an information reminding scenario, as shown in the drawing, there is a cross line of sight range between the first line of sight range of the first user and the second line of sight range of the second user, that is, the first user/the second user can see the scene in the cross line of sight range, and in the corresponding cross line of sight range, there may be at least one atmosphere lamp (first atmosphere lamp/second atmosphere lamp), then, the first user and the second user may be alerted by different rhythm policies for the first atmosphere lamp and the second atmosphere lamp, for example, the first atmosphere lamp and the second atmosphere lamp may be controlled to perform the rhythm at the same time, so that the first atmosphere lamp and the second atmosphere lamp achieve alternate flickering, that is, the second atmosphere lamp does not blink when the first atmosphere lamp blinks, or the second atmosphere lamp blinks when the first atmosphere lamp does not blink, and the atmosphere lamp residing in the cross line of sight range may not blink, or may alternately perform the second rhythm policy and the third rhythm policy (regular blinking of one or two colors at a certain frequency), for example, if the first atmosphere lamp is in the round, the lamps in the cross line of sight range perform the second rhythm policy, and if the second atmosphere lamp is in the round, perform the third rhythm policy.

In a specific implementation, for example, the first atmosphere lamp and the second atmosphere lamp can be controlled to perform the rhythm at the same time, so that the first atmosphere lamp and the second atmosphere lamp can flash alternately.

Optionally, the method may further include the steps of: if the vehicle is detected to be in an overspeed state, determining a current scene, determining a target safe vehicle speed corresponding to the current scene according to a mapping relation between a preset safe vehicle speed and the preset scene, and controlling the vehicle to decelerate to the target safe vehicle speed.

The preset scene may be set by the user or default by the system, which is not limited herein; the preset scene may include at least one of: the high-speed driving scene, the city driving scene, the mountain driving scene, the rainy and snowy weather driving scene, and the like are not limited herein.

The vehicle-mounted device can preset different mapping relations between preset scenes and safe vehicle speeds, the safe vehicle speeds can refer to safe driving vehicle speeds, and the safe driving vehicle speeds can be a range.

In the specific implementation, if the vehicle-mounted device detects that the vehicle is in an overspeed state, the current scene can be determined, the target safe vehicle speed is determined according to the current scene, and the vehicle is controlled to be decelerated to the target safe vehicle speed.

Optionally, the method may further include the steps of: after the vehicle is controlled to be decelerated to the target safe vehicle speed, determining that the first user is in a safe vehicle speed driving state; determining a fourth rhythm strategy corresponding to the safe vehicle speed driving state according to a mapping relation between a preset user driving state and a preset rhythm strategy; and controlling the first atmosphere lamp to perform rhythm according to the fourth rhythm strategy, wherein the fourth rhythm strategy is used for reminding the first user of being in a safe vehicle speed driving state.

The vehicle-mounted equipment can remind the user of being in an overspeed state through the first atmosphere lamp so as to remind the user of decelerating; for example, after the user reaches the target vehicle speed, the user can be determined to be in a safe driving state, a fourth rhythm strategy corresponding to the safe driving state can be determined according to a mapping relation between the preset user driving state and the preset rhythm strategy, and the first atmosphere lamp can be controlled to carry out the fourth rhythm strategy so as to remind the user of being in the safe driving state currently.

Of course, when the user is in the overdrive state, the first atmosphere lamp is controlled to flash or normally light with red light, and after the user is decelerated to the target safe speed, i.e. if the user is in the safe driving state, the first atmosphere lamp is controlled to flash or normally light with green light, which is favorable for reminding the user of safe driving, and the safe driving awareness of the user can be improved.

It can be seen that, by applying the information reminding method provided by the embodiment of the application to the vehicle-mounted device, the physiological parameter set of the first user can be collected; judging whether the first user is in a fatigue driving state or not according to the physiological parameter set; if the first user is in the fatigue driving state, early warning is carried out on the first user through a first atmosphere lamp corresponding to the first user; if the second user is determined to exist, determining the position information of the second user, and determining a second atmosphere lamp corresponding to the second user according to the mapping relation between the preset position information and the preset atmosphere lamp, wherein the second atmosphere lamp is used for reminding the second user that the first user is in a fatigue driving state so as to help the second user to remind the first user. So, accessible first atmosphere lamp reminds first user to avoid first user fatigue driving, of course, the second user except first user is reminded to the accessible second atmosphere lamp, reminds this first user through the second user, in order to prevent that first user from not receiving the emergence of the warning condition of first atmosphere lamp, is favorable to improving the safety of traveling, is favorable to improving user's warning accuracy.
