Wherein the fourth linkage equipment comprises one or more of a vehicle window, a fresh air fan, an air conditioner, an oxygen generator and a sobering agent diffuser. As can be seen from S402, when it is determined that the fourth fatigue level does not meet the requirement for safe driving, the method for controlling the vehicle may perform one or both of the following two schemes: controlling a fourth linkage device in the vehicle to create a fourth preset environment; and controlling the vehicle to run and adjusting the vehicle speed.

The fatigue driving refers to a general term for physical changes due to driving work, psychological fatigue, and objective measurement of a decline in driving performance when driving a vehicle. In recent years, due to the rapid development of roads, the quantity of automobiles kept is continuously increased, and various problems such as traffic accidents and the like are inevitably brought while convenience is brought to life of people. In the technical scheme, when the fatigue state of the driver is detected, the fatigue can be relieved through the in-vehicle linkage equipment, or the vehicle is temporarily prohibited from running, so that the running safety is ensured.

In an alternative embodiment, as shown in fig. 5, in S102, controlling a first linkage device in a vehicle according to a first body state of a driver includes:

s501, determining a first state grade of the first body state of the driver according to the first matching degree of the first body state of the driver and the requirement of safe driving.

The first matching degree of the first physical state of the driver and the requirement of safe driving is used for representing the degree of suitability for driving of the driver in the first physical state, for example, the higher the first matching degree is, the more suitable the driver in the first physical state is for driving the vehicle, whereas, the lower the first matching degree is, the less suitable the driver in the first physical state is for driving the vehicle.

The first state level is one of two or more state levels divided according to a difference in matching degree of the physical state of the driver with the requirement of safe driving. The two or more state grades may be arranged in the order of the matching degree of the physical state with the requirement of safe driving from high to low, or may be arranged in the order of the matching degree of the physical state with the requirement of safe driving from low to high.

It is stated above that the first body condition comprises one or more of an intoxication level, a fatigue level and a wakefulness level, and correspondingly, the first condition level is one or more of two or more intoxication levels, two or more fatigue levels and two or more wakefulness levels.

the first control strategy is one of two or more control strategies for controlling the first linkage equipment, and the first control strategy comprises the type of the started linkage equipment and the operation parameters of the linkage equipment. Different actuated linkage types and different linkage operating parameters may be combined to form a plurality of control strategies. For example, a control strategy may include: opening an air conditioner, and setting the temperature to be 26 ℃; another control strategy includes: the air conditioner was turned on and the temperature was set at 25 ℃.

And S503, controlling the first linkage equipment in the vehicle to operate according to the first control strategy.

In the technical scheme, the first physical state of the driver corresponds to the first control strategy of the first linkage equipment in the vehicle, after the first linkage equipment is operated under the first control strategy, a first preset environment can be formed in the vehicle, the first physical state of the driver can be relieved in the first preset environment, and the matching degree of the first physical state of the driver and the safe driving condition is increased. For example, the fatigue degree of the driver can be relieved, and the driver can drive continuously; the drunk degree of the driver is gradually reduced, and the driver is ensured to be recovered to the physical state meeting the safe driving requirement in the shortest time. Namely, the first preset environment obtained after the first linkage equipment operates according to the first control strategy has the effect of relieving the physical state of the driver. The first linkage equipment has different relieving effects on the physical state of the driver in the preset environment obtained after the first linkage equipment operates according to different control strategies, and therefore each control strategy corresponds to one relieving effect on the physical state of the driver. Optionally, the two or more control strategies for controlling the first linkage are arranged in order of decreasing relief effect on the physical state of the driver; or, two or more control strategies for controlling the first linkage are arranged in order of decreasing effect on the physical state of the driver. This technical scheme belongs to the first aggregate unit in the control car to build the scheme of first default environment.

In an alternative embodiment, as shown in fig. 6, applied to a starting process of a vehicle, S202 controls a second in-vehicle linkage device according to a second degree of intoxication of the driver, comprising:

s601, determining a second drunk grade of the second drunk degree according to the second drunk degree of the driver and a second matching degree of the safe driving requirement;

wherein the second degree of matching is used to characterize a degree to which a driver who is at the second degree of intoxication is fit for driving. The second intoxication level is one of two or more intoxication levels divided according to the difference of the degree of intoxication of the driver from the requirement of safe driving. For example, three intoxication ratings are set, respectively: mild drunkenness, moderate drunkenness and severe drunkenness. Optionally, the two or more intoxication levels are arranged in order of degree of intoxication matching the requirement of safe driving; or, the two or more drunk grades are arranged in the order of matching the drunk degree with the requirement of safe driving from low to high. And determining a second control strategy according to the second drunk grade in the subsequent step.

S602, determining a second control strategy for controlling the second linkage equipment according to the second drunk level;

the second control strategy is one of two or more control strategies for controlling the second linkage equipment, and the second control strategy comprises the type of the started linkage equipment and the operation parameters of the linkage equipment. As noted above, the second linkage includes one or more of a window, a fresh air fan, an air conditioner, an oxygen generator, and a freshener dispenser, and the second control strategy is for controlling a linkage that adjusts an air environment in the vehicle, including: one or more of vehicle window, fresh air machine, air conditioner, oxygen generator and refreshing agent diffuser.

And S603, controlling the second linkage equipment to operate according to a second control strategy.

In the technical scheme, the action of the second linkage device has no necessary relation with whether the vehicle engine is started or not, the second linkage device can be started independently, the vehicle engine can be started independently, and the second linkage device and the vehicle engine can be started simultaneously.

In the technical scheme, the second body state of the driver corresponds to the second control strategy of the second linkage device, the second linkage device can form a second preset environment in the vehicle after running under the second control strategy, and when the driver is in the second preset environment, the drunk state can be relieved, so that the driver can be recovered to the state meeting the safe driving requirement in the shortest time. Namely, after the second linkage equipment is controlled to operate according to the second control strategy, the effect of alleviating the drunkenness is achieved. Optionally, the two or more control strategies for controlling the second linkage are arranged in order of decreasing relief effect on the degree of intoxication of the driver; alternatively, the two or more control strategies for controlling the second linkage are arranged in order of decreasing effect on the driver's intoxication degree. The technical scheme belongs to a scheme for controlling second linkage equipment in a vehicle to create a second preset environment. When two or more control strategies are arranged in the above-mentioned set order, it is convenient to determine a second control strategy for controlling the second linkage arrangement based on the second intoxication level.

It can be seen that there is a difference in the effects of the two or more control strategies for controlling the second linkage in alleviating intoxication. Further, in two or more control strategies for controlling the second linkage arrangement, there may be differences in the kind of arrangement controlled or in the operating parameters of the control arrangement.

For example, in the control strategy for controlling the second linkage, which is the least effective in alleviating intoxication, the control linkage is in a default state. In a default state, the driver may manually operate, adjust the second linkage. The control strategy is suitable for the situation that the driver is slightly drunk, when the driver is slightly drunk, the sobriety degree of the driver is higher, and the second linkage equipment can be operated and adjusted to obtain a better environment in the vehicle.

In a control strategy for controlling the second linkage equipment with a moderate effect of alleviating the drunkenness, if the temperature in the vehicle is determined not to be within a first set temperature range, controlling the air conditioner to be matched with the vehicle window so that the temperature in the vehicle reaches the first set temperature range, wherein the first set temperature range comprises a highest temperature value and a lowest temperature value, when the temperature in the vehicle is higher than the highest temperature value, the temperature in the vehicle needs to be reduced, and when the temperature in the vehicle is lower than the lowest temperature value, the temperature in the vehicle needs to be increased; for example, the air conditioner comprises a temperature sensor and a temperature adjusting device, when the temperature in the vehicle obtained by the temperature sensor is not within a first set temperature range, the window is controlled to be closed, the temperature adjusting device is controlled to be opened, and the temperature in the vehicle is adjusted until the temperature in the vehicle reaches the first set temperature range; optionally, the air conditioner further comprises an infrared sensor operable to detect whether the driver is in the vehicle.

Optionally, in the process of adjusting the temperature in the vehicle, when the vehicle window is controlled to be closed, the fresh air fan is controlled to be opened to exchange air.

If the temperature in the vehicle is determined to be within the first set temperature range, controlling the fresh air fan and the vehicle window to change air; opening the car window, wherein the opening degree of the car window corresponds to a second drunk degree, and the higher the second drunk degree is, the smaller the opening degree of the car window is; the opening degree of the fresh air fan is inversely related to the opening degree of the car window, and the smaller the opening degree of the car window is, the larger the opening degree of the fresh air fan is. The flowing of air in the vehicle is ensured, and the drunk degree of the driver is changed.

In a control strategy for controlling the second linkage equipment with the strongest effect of alleviating the drunk, the vehicle window, the air conditioner, the fresh air fan and the oxygen generator are simultaneously controlled to simultaneously regulate the environment in the vehicle. For example, the vehicle window is controlled to be closed, the temperature in the vehicle is controlled to be within a second set temperature range through the air conditioner, the fresh air fan is turned on to exchange air, and the oxygen concentration in the vehicle is controlled to be within a first set oxygen range through the oxygen generator. And if the temperature in the vehicle is determined to be not within the second set temperature range, controlling the air conditioner to be started, adjusting the temperature in the vehicle to be within the second set temperature range, and if the temperature in the vehicle is determined to be within the second set temperature range, controlling the air conditioner to be stopped to be closed. The oxygen concentration in the vehicle is related to the second drunk degree, the higher the second drunk degree is, the higher the oxygen concentration in the vehicle is, and the oxygen concentration in the vehicle is controlled to be always in the first set temperature range through the oxygen generator. Optionally, the oxygen generator can be installed inside a vehicle engine hood, an air outlet of the oxygen generator is communicated with an air outlet of an air conditioner and/or an air outlet of a fresh air machine, and an independent switch is arranged at the air outlet of the oxygen generator and used for controlling the opening degree. The above arrangement scheme can lead the oxygen output by the oxygen generator to be diffused through the air outlet of the air conditioner and/or the air outlet of the fresh air fan.

As shown in fig. 7, in an alternative embodiment, applied to the driving process of the vehicle, S402 controls a fourth in-vehicle linkage device according to a fourth fatigue level of the driver, including:

s701, determining a fourth fatigue grade of the fourth fatigue degree according to the fourth matching degree of the fourth fatigue degree and the requirement of safe driving;

wherein the fourth matching degree is used for representing the degree that the driver under the fourth fatigue degree is suitable for driving. The fourth grade is one of two or more fatigue grades divided according to a difference between the degree of fatigue of the driver and the fourth matching degree of the requirement of safe driving. Optionally, the two or more fatigue levels are arranged in order of the fourth matching degree of the fatigue degree and the requirement of safe driving; or, the two or more fatigue grades are arranged according to the sequence of the fourth matching degree of the fatigue degree and the requirement of safe driving from low to high. For example, the fatigue degree may be divided into three fatigue levels, and the three fatigue levels may be arranged in sequence from low to high according to the fourth matching degree between the fatigue degree and the requirement of safe driving: mild fatigue, moderate fatigue and severe fatigue. The three fatigue levels are only given as an example, and the number of fatigue levels dividing the fatigue level is not limited, and the fatigue level may be divided into two or more fatigue levels or three or more fatigue levels according to actual needs.

S702, determining a fourth control strategy for controlling a fourth linkage device according to the fourth fatigue level;

wherein the fourth control strategy is one of two or more control strategies for controlling a fourth linkage device, and the fourth control strategy includes the type of the device being started and the operating parameters of the device. As can be seen from the above, the fourth linkage device includes one or more of a vehicle window, a fresh air machine, an air conditioner, an oxygen generator, a sobering agent disperser, an audio device, and a central control screen, and then the fourth control strategy is used for controlling the device capable of adjusting the air environment in the vehicle, and includes: one or more of vehicle window, fresh air machine, air conditioner, oxygen generator and refreshing agent diffuser.

And S703, controlling the fourth linkage equipment to operate according to a fourth control strategy.

In the technical scheme, the fourth physical state of the driver corresponds to the fourth control strategy of the fourth linkage device, the fourth linkage device can form a fourth preset environment in the vehicle after running under the fourth control strategy, and when the driver is in the fourth preset environment, the fatigue state is favorably relieved, so that the driver can be recovered to the state meeting the safe driving requirement in the shortest time. Namely, after the fourth linkage equipment is controlled to operate according to the fourth control strategy, the effect of relieving fatigue is achieved. Optionally, the two or more control strategies for controlling the fourth linkage device are arranged in order of decreasing effect of alleviating the fatigue degree of the driver; alternatively, two or more control strategies for controlling the fourth linkage may be arranged in order of decreasing effect on the fatigue level of the driver. This technical scheme belongs to the fourth aggregate unit in the control car to build the scheme of fourth default environment. When two or more control strategies for controlling the fourth linkage are arranged in a set order, it is convenient to determine a fourth control strategy for controlling the fourth linkage based on the fourth fatigue level.

In two or more control strategies for controlling the fourth linkage, there may be differences in the kind of devices and/or the operating books of the devices that are activated by different control strategies. In one application scenario, the control strategy for controlling the fourth linkage device is divided into three strategies, and the fatigue relieving effects are as follows: weakest, medium and strongest, respectively corresponding to different fatigue levels. The differences existing between the control strategies and the correspondence of the control strategies to the fatigue levels are exemplarily described below.

And in the control strategy for controlling the fourth linkage equipment with the weakest fatigue relieving effect, the freshness of the air in the vehicle is maintained within a first set freshness range by controlling the vehicle window and/or the fresh air machine. The control strategy is suitable for the situation that the driver has light fatigue. In mild fatigue, a number of different degrees of fatigue are also included. The first set freshness range is related to fatigue degree, and the higher the fatigue degree is, the higher the requirement on the freshness of air in the vehicle is. Correspondingly, the higher the fatigue degree is, the larger the opening degree of the control window is; when the control window is closed, the fatigue degree is higher, and the air quantity of the fresh air fan is controlled to be larger. In addition, the vehicle window and the fresh air fan can be opened simultaneously, and the ventilation volume of air in the vehicle can be determined after the fatigue degree is determined. And under the condition that the ventilation volume in the vehicle is not changed, controlling the opening of the vehicle window to be reduced and controlling the air volume of the fresh air fan to be increased. Optionally, the opening of the window is also related to the vehicle speed, i.e. the opening of the window is controlled in dependence of the fourth fatigue level and the vehicle speed. For example, when it is determined that the vehicle speed is less than 50km/h, the opening degree of the window is controlled according to the fourth fatigue level; and when the vehicle speed is determined to be greater than or equal to 50km/h, closing the vehicle window, and controlling the air volume of the fresh air fan according to the fourth fatigue level.

In the near infrared spectrum alcohol content measurement, the alcohol content is usually determined by analyzing the frequency doubling or frequency combining absorption peaks of alcohol C-H bonds and O-H bonds, so that the detection of the alcohol concentration in blood can be realized by a near infrared spectrum technology.

In an alternative embodiment, the second physiological information of the driver is acquired by the integrated detection device.

In general, when people feel tired and doze, eyes usually blink frequently and the eyes are closed for a long time.

The fatigue degree may be divided into two, or, three, or more fatigue levels, taking as an example the division of the fatigue degree into 3 fatigue levels (light fatigue, medium fatigue, and heavy fatigue), when the heart rate reaches N1, the driver is determined to be in light fatigue, when the heart rate reaches N2, the driver is determined to be in medium fatigue, when the heart rate reaches N3, the driver is determined to be in heavy fatigue.
