Fatigue driving refers to the general term for physical changes, psychological fatigue, and objective measurement of poor driving performance when driving a vehicle. In recent years, with the rapid development of roads, the number of cars has kept rising, while bringing convenience to people's lives, it can inevitably bring many problems such as traffic accidents. In this technical solution, when it is detected that the driver is in a fatigue state, the fatigue can be relieved through the in-vehicle linkage device, or the vehicle is temporarily prohibited from driving, thereby ensuring the safety of driving.

As shown in FIG. 5, in an optional embodiment, in S102, controlling the first linkage device in the vehicle according to the first physical state of the driver includes:

S501. Determine a first state level in which the driver's first physical state is located according to a first matching degree between the first physical state of the driver and a requirement for safe driving.

The first matching degree between the driver ’s first physical state and the requirements for safe driving is used to characterize the driver ’s suitability for driving under the first physical state. For example, the higher the first matching degree, the more A driver in a physical state is more suitable for driving a vehicle, and conversely, the lower the first matching degree is, the less suitable the driver is in the first physical state.

The first state level is one of two or more state levels, and the two or more state levels are divided according to the degree of matching between the driver's physical state and the requirements of safe driving. The two or more status levels may be arranged in a descending order of the matching degree between the physical state and the requirements for safe driving, and may also be arranged in the descending order of the matching degree between the physical state and the requirements for safe driving.

It was explained above that the first physical state includes one or more of a degree of drunkenness, a degree of fatigue, and a degree of awakeness. Correspondingly, the first state level is two or more intoxication levels, two or more fatigue levels and two One or more of one or more levels of sobriety.

S502. Determine the first control strategy of the first linkage device in the vehicle according to the first status level;

The first control strategy is one of two or more control strategies for controlling the first linkage device, and the first control strategy includes the type of the linkage device to be started and the operating parameters of the linkage device. Different activated linkage equipment types and different linkage equipment operating parameters can be combined to form multiple control strategies. For example, a certain control strategy may include: turning on the air conditioner with a set temperature of 26 ° C; another control strategy includes: turning on the air conditioner with a set temperature of 25 ° C.

S503. Control the operation of the first linkage device in the vehicle according to the first control strategy.

In this technical solution, the first physical state of the driver corresponds to the first control strategy of the first linkage device in the car, and after the first linkage device is operated under the first control strategy, a first pre-set can be formed in the vehicle. Given the environment, the driver's first physical state will be alleviated in the first preset environment, so that the degree of matching between the driver's first physical state and the conditions for safe driving becomes higher. For example, the driver's fatigue will be relieved and the driver can continue to drive; the driver's drunken degree is gradually reduced to ensure that the driver recovers to a physical state that meets the requirements of safe driving in the shortest time. That is, the first preset environment obtained after the first linkage device operates according to the first control strategy has the effect of alleviating the physical state of the driver. The preset linkage environment obtained after the first linkage device operates according to different control strategies has different mitigation effects on the driver's body state. Then, each control strategy corresponds to a mitigation effect on the driver's body state. Optionally, two or more control strategies for controlling the first linkage device are arranged in descending order of the relief effect on the physical state of the driver; or, two or more are used for controlling the first linkage device. The device's control strategy is arranged in ascending order of the effect on the driver's physical condition. This technical scheme belongs to a scheme for controlling the first linkage device in a vehicle to create a first preset environment.

As shown in FIG. 6, in an optional implementation manner, which is applied to the startup process of the vehicle, S202 controls the second linkage device in the vehicle according to the second drunkenness of the driver, including:

S601. Determine a second intoxication level at which the second intoxication level is located according to a second matching degree between the second intoxication degree of the driver and the requirements for safe driving;

Wherein, the second matching degree is used for characterizing the degree that the driver at the second drunk degree is suitable for driving. The second drunkness level is one of two or more drunkness levels, and the two or more drunkness levels are divided according to the difference in the degree of matching between the driver's drunkness level and the requirements for safe driving. For example, set three levels of drunkenness: light drunk, moderate drunk, and severe drunk. Optionally, two or more intoxication levels are arranged in descending order according to the degree of matching between the degree of drunkness and the requirements for safe driving; or, two or more intoxication levels are according to the degree of matching between the level of drunkness and the requirements for safe driving Sort from low to high. It is convenient for determining the second control strategy according to the second intoxication level in the subsequent steps.

S602. Determine a second control strategy for controlling the second linkage device according to the second drunkenness level;

The second control strategy is one of two or more control strategies for controlling the second linkage device, and the second control strategy includes the type of linkage equipment to be started and the operating parameters of the linkage equipment. It can be known from the foregoing that the second linkage device includes one or more of a window, a fresh air blower, an air conditioner, an oxygen generator, and a lucidizer diffuser. Then, the second control strategy is used to control the adjustable indoor air environment. Linkage equipment, including: one or more of windows, new fans, air conditioners, oxygen generators and lucidizer diffusers.

S603. Control the operation of the second linkage device according to the second control strategy.

In this technical solution, the action of the second linkage device is not necessarily related to whether the vehicle engine is started. The second linkage device can be started separately, the vehicle engine can be started separately, and the second linkage device and the vehicle engine can be started simultaneously.

In this technical solution, the second physical state of the driver corresponds to the second control strategy of the second linkage device. After the second linkage device operates under the second control strategy, a second preset environment can be formed in the vehicle. When the driver is in the second preset environment, it is beneficial to alleviate the drunk state, so as to recover to a state that meets the requirements of safe driving in the shortest time. That is, after controlling the operation of the second linkage device according to the second control strategy, it has the effect of alleviating drunkenness. Optionally, two or more control strategies for controlling the second linkage device are arranged in descending order of the effect of reducing the drunkenness of the driver; or, two or more are used for controlling the second The control strategy of the linked equipment is arranged in order of the effect of reducing the drunkenness of the driver from low to high. This technical scheme belongs to a scheme for controlling a second linkage device in a vehicle to create a second preset environment. When two or more control strategies are arranged in the above-mentioned setting order, it is convenient to determine a second control strategy for controlling the second linkage device according to the second drunkenness level.

It can be seen that there are differences in the effect of two or more control strategies for controlling the second linkage device to alleviate drunkenness. Further, in two or more control strategies for controlling the second linkage device, there is a difference in the type of the device to be controlled or the operating parameter of the control device.

For example, in the control strategy for controlling the second linkage device that has the weakest effect of reducing drunkenness, the control linkage device is in a default state. In the default state, the driver can manually operate and adjust the second linkage device. This control strategy is applicable to the situation where the driver is slightly drunk. When the driver is slightly drunk, the driver is relatively awake and can operate and adjust the second linkage device to obtain a better interior environment.

In the control strategy for controlling the second linkage device whose effect of reducing drunkenness is medium, if it is determined that the temperature inside the vehicle is not within the first set temperature range, the air conditioner is controlled to cooperate with the window to make the temperature inside the vehicle reach the first Set temperature range. The first set temperature range includes a maximum temperature value and a minimum temperature value. When the temperature inside the car is higher than the maximum temperature value, the temperature inside the car needs to be reduced. When the temperature inside the car is lower than the minimum temperature value, The temperature inside the car needs to be increased; for example, the air conditioner includes a temperature sensor and a temperature adjustment device. When the temperature inside the car obtained by the temperature sensor is not within the first set temperature range, the window is controlled to close, the temperature adjustment device is opened, and The temperature in the vehicle is adjusted until the temperature in the vehicle reaches a first set temperature range; optionally, the air conditioner further includes an infrared sensor, which can be used to detect whether the driver is in the vehicle.

Optionally, in the above-mentioned process of adjusting the temperature inside the vehicle, when the window of the vehicle is controlled to be closed, the new fan is controlled to be opened to perform air exchange.

If it is determined that the temperature inside the car is within the first set temperature range, control the new fan and the window to change the air; at this time, open the window, and the opening of the window corresponds to the second drunk degree, the higher the second drunk degree , The smaller the opening of the window; the opening of the new fan is inversely related to the opening of the window. The smaller the opening of the window, the larger the opening of the new fan. Ensure the air flow in the car, in exchange for the degree of drunkenness of the driver.

In the control strategy for controlling the second linkage device with the strongest effect of relieving drunkenness, the windows, air conditioners, fresh air fans, and oxygen generators are controlled at the same time to adjust the environment inside the car. For example, the windows of the vehicle are controlled to be closed, the temperature inside the vehicle is controlled to be within the second set temperature range by the air conditioner, and the new fan is turned on for ventilation, and the oxygen concentration in the vehicle is controlled to be within the first set range of oxygen. Among them, if it is determined that the temperature inside the car is not within the second set temperature range, the air conditioner is controlled to be turned on, and the temperature inside the car is adjusted to the second set temperature range. If it is determined that the temperature inside the car is within the second set temperature range, the air conditioner is controlled Stop closing. The oxygen concentration in the car is related to the second drunk degree. The higher the second drunk degree, the higher the oxygen concentration in the car. The oxygen concentration in the car is controlled by the oxygen generator to always be within the first set temperature range. Optionally, the oxygen generator can be installed inside the vehicle hood, and its air outlet is connected with the air conditioner air outlet and / or the new fan air outlet. The air outlet of the oxygen generator is provided with an independent switch for controlling the opening degree. The above arrangement scheme can cause the oxygen output from the oxygen generator to be emitted through the air outlet of the air conditioner and / or the air outlet of the new fan.

As shown in FIG. 7, in an optional embodiment, which is applied to the driving process of the vehicle, S402 controls the fourth linkage device in the vehicle according to the fourth degree of fatigue of the driver, including:

S701. Determine a fourth fatigue level at which the fourth fatigue level is located according to a fourth matching degree between the fourth fatigue level and requirements for safe driving;

Among them, the fourth matching degree is used to characterize a driver's suitability for driving at the fourth fatigue level. The fourth level is one of two or more fatigue levels, and the two or more fatigue levels are divided according to a difference between a driver's fatigue level and a fourth matching degree required for safe driving. Optionally, the two or more fatigue levels are arranged in order of the fourth matching degree of the fatigue level and the requirements for safe driving; or, the two or more fatigue levels are arranged according to the fatigue level and the requirements of safe driving. The fourth matching degree is arranged from low to high. For example, the degree of fatigue can be divided into three fatigue levels, and in accordance with the order of the fourth degree of matching between the degree of fatigue and the requirements for safe driving, the three fatigue levels can be arranged in order: mild fatigue, moderate Fatigue and severe fatigue. The three fatigue levels listed here are just examples, and the number of fatigue levels divided into fatigue levels is not limited. According to actual needs, the fatigue levels can be divided into two or more fatigue levels, and the fatigue levels can be divided into three. Or multiple fatigue levels.

S702. Determine a fourth control strategy for controlling the fourth linkage device according to the fourth fatigue level;

The fourth control strategy is one of two or more control strategies for controlling the fourth linkage device. The fourth control strategy includes the type of the device to be started and the operating parameters of the device. It can be known from the foregoing that the fourth linkage device includes one or more of a window, a new fan, an air conditioner, an oxygen generator, a lucidizer diffuser, an audio device, and a central control screen. Then, the fourth control strategy is used to control Equipment that can adjust the air environment in the car, including: one or more of windows, fresh air fans, air conditioners, oxygen generators and lucidizer diffusers.

S703. Control the operation of the fourth linkage device according to the fourth control strategy.

In this technical solution, the fourth physical state of the driver corresponds to the fourth control strategy of the fourth linkage device. After the fourth linkage device operates under the fourth control strategy, a fourth preset environment can be formed in the vehicle. When the driver is in the fourth preset environment, it is beneficial to alleviate the fatigue state so as to recover to a state that meets the requirements of safe driving in the shortest time. That is, after controlling the operation of the fourth linkage device according to the fourth control strategy, it has the effect of alleviating fatigue. Optionally, two or more control strategies for controlling the fourth linkage device are arranged in descending order of the effect of reducing the driver's fatigue; or two or more control strategies for controlling the fourth The control strategy of the linkage equipment is arranged in order of the effect of reducing the driver's fatigue. The technical scheme belongs to a scheme for controlling a fourth linkage device in a car to create a fourth preset environment. When two or more control strategies for controlling the fourth linkage device are arranged in a set order, it is convenient to determine a fourth control strategy for controlling the fourth linkage device according to the fourth fatigue level.

In the two or more control strategies for controlling the fourth linkage device, there are differences in the types of devices activated by different control strategies and / or operation books of the devices. In one application scenario, the control strategy for controlling the fourth linkage device is divided into three, and the fatigue relief effects are: weakest, medium, and strongest, respectively, corresponding to different fatigue levels. The following exemplifies the differences between control strategies and the correspondence between control strategies and fatigue levels.

In the control strategy for controlling the fourth linkage device that has the weakest effect of reducing fatigue, maintaining the freshness of the air in the vehicle within the first set freshness range by controlling the windows and / or the new fan. This control strategy is suitable for scenarios where the driver has mild fatigue. In mild fatigue, there are many different degrees of fatigue. The first range of freshness is related to the degree of fatigue. The higher the degree of fatigue, the higher the requirement for the freshness of the air in the vehicle. Correspondingly, the higher the degree of fatigue, the greater the opening of the control window; when the window is closed, the higher the degree of fatigue, the greater the air volume of the new fan. In addition, you can also choose to open the window and the new fan at the same time, and after determining the degree of fatigue, you can determine the amount of air exchange in the car. Under the condition that the ventilation volume in the car is unchanged, the opening degree of the control window is reduced, and the air volume of the new fan is increased. Optionally, the opening degree of the window is also related to the vehicle speed, that is, the opening degree of the window is controlled according to the fourth fatigue level and the vehicle speed. For example, when it is determined that the vehicle speed is less than 50 km / h, the opening degree of the window is controlled according to the fourth fatigue level; when it is determined that the vehicle speed is 50 km / h or more, the window is closed and the air volume of the new fan is controlled according to the fourth fatigue level. In addition, when it is determined that the driver has mild fatigue and it is determined that the air conditioner in the vehicle is turned on, the temperature in the vehicle is controlled by the air conditioner to reduce the first set temperature value, wherein the first set temperature value may be 1 ° C to Any temperature of 2 ° C. For example, the first set temperature value may be any of 1 ° C, 1.5 ° C, and 2 ° C.

In the control strategy for controlling the fourth linkage device with a moderate effect of reducing fatigue, the oxygen content in the vehicle is controlled to be within the first set oxygen content range by controlling the oxygen generator and / or the new fan. This control strategy is suitable for the scenario where the driver has moderate fatigue. In moderate fatigue, the first set oxygen content is the safety limit of the oxygen content in the car. In moderate fatigue, there are many different degrees of fatigue. In the process of controlling the oxygen generator and / or the new fan, it can be controlled in various ways. For example, an optional control method is: controlling the oxygen generator and the new fan to be turned on at the same time, and the oxygen supply air volume of the oxygen generator The ratio between the fresh air volume and the fresh air volume of the new fan is the first ratio. The first ratio is positively related to the degree of fatigue. The higher the degree of fatigue, the larger the first ratio. Another optional control method is: controlling the oxygen generator and the new fan to turn on alternately. The product of the oxygen generator's turn-on time and the supply air flow rate is the first product. The product of time is the second product. The ratio of the first product to the second product is the second ratio. The second ratio is positively related to the degree of fatigue. The higher the degree of fatigue, the larger the second ratio. The above-mentioned control methods for the oxygen generator and the new fan are also applicable to the control strategy for reducing drunkenness. Regarding the above oxygen generator, optionally, the oxygen generator can be installed and connected to the interior of the vehicle hood, and the air outlet of the oxygen generator is in communication with the air conditioner air outlet and / or the new fan air outlet, and the air outlet of the oxygen generator is provided with an independent switch for Control the amount of opening. The above arrangement scheme can cause the oxygen output from the oxygen generator to be emitted through the air outlet of the air conditioner and / or the air outlet of the new fan. Optionally, the control strategy further includes: controlling the temperature in the vehicle by the air conditioner to lower the second set temperature value, wherein the second set temperature value is greater than the first set temperature value, The value can range from 3 ° C to 4 ° C. For example, the second set temperature value can be any one of 3 ° C, 3.5 ° C, and 4 ° C. Optionally, in the control strategy, the method further includes: controlling the awake dispenser to release the awake agent at a low level. Among them, the conscious agent is a diluent of a refreshing liquid such as wind olein, refreshing oil, the conscious agent diffuser may be a liquid volatile device such as a perfume volatile device, a humidifier, and the conscious agent diffuser may control the amount of the conscious agent.

In the control strategy for controlling the fourth linkage device with the strongest effect of reducing fatigue, the oxygen content in the vehicle is controlled to be within the second set oxygen content range by controlling the oxygen generator and / or the new fan, and the control The strategy is applicable when the driver is experiencing severe fatigue. The second set oxygen content is the safety limit of the oxygen content in the car when the driver is in a severe fatigue state. It was mentioned above that when the driver has moderate fatigue, controlling the oxygen content in the vehicle to be in the first set oxygen content range, obviously, the second set oxygen content range is more suitable for reducing fatigue than the first set oxygen content range. In the process of controlling the oxygen generator and / or the new fan, there are various ways to control it. For specific control methods, please refer to the application scenario when the driver is in moderate fatigue, which is not repeated here. Optionally, the control strategy further includes: controlling the temperature in the vehicle by the air conditioner to lower the third set temperature value, wherein the third set temperature value is greater than the second set temperature value, and the third set temperature value The value range can be: 5 ° C to 6 ° C. For example, the third set temperature value can be any one of 5 ° C, 5.5 ° C, and 6 ° C. Optionally, the control strategy further includes: controlling the conscious agent diffuser to release the conscious agent at a high level.

Among them, the prohibition of the vehicle running, including the prohibition of the vehicle starting, can be controlled by controlling the starting device to control whether the vehicle is prohibited from starting, or the vehicle cannot run after the engine is started.

Although the drinking driver was unable to drive the vehicle, other authorized non-drinking drivers could still drive the vehicle following normal procedures. When it is determined that the physical state of the driver meets the conditions for safe driving, the first linkage device is controlled to restore the default state. Among them, the driver's physical condition meets the requirements for safe driving, which means that the driver is authorized, the driver is not drinking, and the driver is low in fatigue.

When the fourth linkage device includes a vehicle speed detector, the vehicle speed is controlled by the vehicle speed controller to be less than or equal to the fourth speed, wherein the fourth speed corresponds to the fourth fatigue level, and the higher the degree of fatigue characterized by the fourth fatigue level, the fourth The smaller the speed. For example, when the fourth fatigue level is moderate fatigue, the fourth speed is 50km / h to 70km / h, and the fourth speed may be: 50km / h, 55km / h, 60km / h, 65km / h, and 70km / h Any one of them. When the fourth fatigue level is severe fatigue, the fourth speed is 30km / h to 45km / h, and the fourth speed may be any one of: 30km / h, 35km / h, 40km / h, and 45km / h. When the fourth fatigue level is beyond the range of severe fatigue, the fourth speed may be between 10km / h and 25km / h, among which the fourth speed may be 10km / h, 15km / h, 20km / h, 25km / h Any one of them.

When the fourth linkage device includes a fourth reminder device, the fourth reminder device is controlled to send a reminder to the driver in a fourth cycle, where the fourth cycle corresponds to the fourth fatigue level, and the fatigue level represented by the fourth fatigue level increases. High, the shorter the fourth cycle. For example, the fourth cycle when the fourth fatigue level is moderate fatigue is 1/2 or less of the fourth cycle when the fourth fatigue level is mild fatigue.

Under normal circumstances, when people are tired and dozing, their eyes blink frequently and their eyes are closed for a long time. For example, when a person is not fatigued, the time for which the eyes are closed is generally between 0.2s and 0.3s.

Forced overtaking, acceleration and deceleration, ignoring signals, and slow driving behavior will increase the heart rate. In general, first, when people are strongly stimulated and nervous, the heart rate will increase, generally 20% faster. When the speed of the vehicle increases, the heart rate also increases. Therefore, the heart rate is closely related to the driving state of the driver.
