Fatigue driving refers to a phenomenon in which a driver experiences a disorder in physiological and psychological functions after driving for a long time, and the driving skill is objectively reduced. Fatigue driving affects the driver's attention, feeling, perception, thinking, judgment, consciousness, decision and movement, for example, the driver may appear as: drowsiness, weakness of limbs, inattention, impaired judgment, even absentmindedness or even instant memory loss. Once the driver is tired, the road traffic accident is easily caused by unsafe factors such as delay of action, operation pause, improper correction time and the like.
There are many factors affecting fatigue driving, such as long-time continuous driving, night driving, insufficient sleeping time or poor sleeping quality, and taking the truck transportation field with the most prominent fatigue driving as an example, relevant research statistics show that at least half of truck drivers can choose to rest or even sleep on the vehicle when feeling drowsy for pursuing short-term economic benefit, and then continuously drive at high speed for a long time in a few night.
In order to meet the requirement that a driver can use an air conditioner during parking when needing to wait for loading and unloading goods frequently or have a rest on the vehicle in the transportation process, a small batch of parking air conditioners are already on the market at present, compared with the traditional vehicle-mounted air conditioner, the parking air conditioner greatly improves the rest quality and the sleep quality of the driver during the rest on the vehicle in the transportation process, and further reduces the fatigue driving probability of the truck to a certain extent, but the parking air conditioner has the problems that the driver feels fatigue by himself or herself in the driving process, particularly at night, and the driver is not willing to actively stop the vehicle for rest and finally incurs irreparable loss in the fatigue process, and the fatigue resisting effect of the parking air conditioner in the field of truck transportation at present is still very limited.

Detailed Description
In order to make the aforementioned objects, technical solutions and advantages of the present invention more comprehensible, the present invention is described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only some of the embodiments constituting the present invention, and are not intended to limit the present invention, and the embodiments and features of the embodiments may be combined with each other without conflict.
Example 1
As shown in fig. 1, the present invention provides an anti-fatigue control method based on a parking air conditioner, comprising the steps of:
s1: the fatigue state monitoring device monitors the driving state information of a driver in real time and carries out timing judgment or real-time judgment on the current driving state;
s2: when meeting first trigger condition, the parking air conditioner opens the mode of releiving automatically, and the mode of releiving wherein means: the parking air conditioner rapidly adjusts one or more of temperature, humidity and oxygen concentration in a compartment to enable the temperature, humidity and oxygen concentration to rapidly reach and continuously keep in a first preset interval;
s3: when the comfort mode is started, the fatigue state monitoring device performs addition calculation on the comfort mode on the basis of a first trigger condition, so that a prejudgment value of the residual healthy driving time length H is obtained, and the prejudgment value is given in a voice broadcasting mode through a vehicle-mounted voice unit and/or in a real-time number indicating mode through a vehicle-mounted display unit;
s4: under the operation of a relieving mode, the fatigue state monitoring device continuously corrects the H value, and gives the H value in a timed broadcasting mode through a vehicle-mounted voice unit and/or in a real-time number display mode through a vehicle-mounted display unit;
s5: when a second trigger condition is met, the parking air conditioner automatically switches to a warning mode from a relieving mode, wherein the warning mode refers to that: on the basis of keeping the existing relieving mode to operate, the parking air conditioner automatically starts a cold air gear face blowing mode with the duration time of T every a first preset time length X.
Specifically, the determination of the current driving state in step S1 may include two states, namely, a healthy driving state and a fatigue driving state, and of course, the two states may be further subdivided according to different degrees; the first preset interval in step S2 may be, for example, (temperature 18-25 ℃, humidity 45% -65%, oxygen concentration 15% -21%); the content of the voice broadcast prompt in step S3 may be set to, for example, "the parking air conditioner comfort mode is turned on, and the healthy driving time in the comfort mode is expected to be H"; the timer interval for the timer broadcast in step S4 may be set to, for example, 10 minutes.
The invention discovers that drivers feel fatigue in driving way, particularly in night, and most drivers are probably not consciously aware of the fatigue when the fatigue comes, and most drivers are usually in a strong subjective intention color for predicting the fatigue, so that the drivers are still reluctant to actively stop and rest during the fatigue and finally cause irreparable loss.
The invention is also obtained by research and analysis, and the reasons for the results are at least two: firstly, a driver is based on the self-perception lack when the fatigue comes, or the perception is seriously lagged so as to cause an illusion, and the driver is blindly confident on the basis of the illusion; secondly, rational cognition (or prejudgment) which is initially established on the basis of subjective intention color in subconscious of the driver cannot be continuously and correctly corrected in the driving process, and the driver is still insisted on the confidence of the driver.
In the embodiment, through the step S3, the objective prediction of the "remaining healthy driving duration H" of the driver for the current driving is initially established, and then the most accurate real-time correction is continuously made on the initial objective prediction through the step S4, the initial objective prediction and the subsequent real-time correction are both established during the initial objective prediction establishment and the subsequent real-time correction, that is, on the basis of the relaxing mode of the step S2, that is, during the whole cognitive process of the H value from the "prediction to the correction" of the current driving, and before the fatigue occurs, the fatigue solution is synchronously fused, so that the occurrence time of the fatigue is delayed to a certain extent, and further during the fatigue occurrence in the step S5, the expected value of the driver for the mileage of the current driving is met to a certain extent, the two factors are cooperated from the perspective of psychological and physiological double layers, and the cold air gear face blowing mode in the step S5 is continuously superposed, so that the subjective intention color of the initial adherence of the driver in subconscious mind is greatly weakened, the driver is more willing to subjectively and actively stop and rest, and the intermittent action of the cold air gear face blowing mode in the step S5 is also helpful for the driver to forcibly keep clear before the active stop and rest, for example, in the process of finding and driving to a nearby parking lot or service area.
Preferably, the first trigger condition is any one of the following conditions:
1) when the driver gives an on instruction;
2) when the fatigue state monitoring device monitors that the same driver continuously drives for more than a third preset time length M;
3) and when the descending rate and/or descending amplitude of the characteristic parameter corresponding to the monitored fatigue state information is larger than or equal to a first characteristic threshold value.
Specifically, there are many factors affecting fatigue driving, wherein driving comfort is taken as one of the important factors, and is relatively controllable relative to other factors such as road conditions, the higher the driving comfort is, the less fatigue is likely to be generated for the driver, and during the driving process of the driver, due to the high tightness of spirit, the driver can not pay close attention to and adjust the driving comfort, especially oxygen concentration, in time, by setting the first trigger condition, the comfort mode of the parking air conditioner can be automatically started according to the start instruction of the driver, or can be forcibly started when the forced trigger condition is met, so that the comfort mode does not need to be started in the whole driving process, the energy saving of the parking air conditioner storage battery is facilitated, especially during spring and autumn, the temperature interval in the first preset interval is likely to be different from the current temperature in the vehicle compartment too much, the primary adjustment at this time would be the oxygen concentration or humidity in the cabin. Of course, as will be understood by those skilled in the art, by setting the first characteristic threshold appropriately, even when the decrease rate or decrease amplitude of the characteristic parameter corresponding to the monitored fatigue state information is greater than or equal to the first characteristic threshold, the driver will be in a healthy driving state.
Preferably, as further shown in fig. 2, the "limp-home mode operation" in step S4 includes the following specific operation steps:
s41: the parking air conditioner judges whether the parking air conditioner is in a starting operation state before the current relieving mode, if so, the step S42 is directly executed; if not, sending a transmission instruction of ensuring that all the windows of the carriage are in a closed state to the vehicle-mounted main control unit, and then executing the step S42;
s42: the parking air conditioner preferentially and quickly adjusts one or more of temperature, humidity and oxygen concentration in the compartment to quickly reach a first preset interval according to the priority sequence of 'the difference between the parking air conditioner and the first preset interval is larger';
s43: and continuously keeping one or more of temperature, humidity and oxygen concentration in the carriage in a first preset interval.
Specifically, in the autonomous operation process after the release mode is started according to the instruction or is forcibly started, the storage battery of the parking air conditioner can be more energy-saving through the ensured operation of closing the window; and the rapid adjustment of the comfort level is preferentially carried out according to the priority order, so that the current comfort level experience of the driver can be improved more rapidly, and the driving time of the driver based on the healthy driving state is prolonged.
Preferably, step S42 includes the following specific operation steps:
s421: when the parking air conditioner needs to perform the autonomous switching of the internal and external circulation modes due to the requirement of quick adjustment, an inquiry instruction is sent to the vehicle-mounted main control unit, and then whether the current road condition environment meets the switching time of the internal and external circulation modes or not is judged through the vehicle-mounted GPS unit;
s422: if yes, the parking air conditioner switches the internal and external circulation modes; if not, executing steps S423 and S424 in sequence;
s423: initiating command call to the vehicle-mounted GPS unit by the parking air conditioner: the method comprises the steps of continuously keeping the vehicle-mounted GPS unit to monitor the current road condition environment in real time, and sending an inquiry instruction of 'whether the autonomous switching of an internal and external circulation mode is needed' to a vehicle-mounted main control unit when the current road condition environment meets a switching condition;
s424: if the parking air conditioner is not needed, the parking air conditioner keeps the existing circulation mode, and instruction calling to the vehicle-mounted GPS unit is stopped.
Specifically, in the process of executing step S42, the original intention of executing step S42 is always that "the current comfort experience of the driver can be improved more quickly, and the driving duration of the driver based on the healthy driving state is improved", rather than the execution means of "quickly adjusting according to the priority order" that is simply and explicitly indicated in step S42, that is, it is not executed for execution, that is, when the external road condition environment does not allow, and when the execution means of "quickly adjusting according to the priority order" is executed in a priority manner, the current comfort experience of the driver may be damaged, and at this time, the processing, such as the delay processing or the slow adjustment, may also be executed in an exceptional manner of "non-priority order" or "non-quick adjustment".
Preferably, the second trigger condition is any one of the following conditions:
1) when the H value in step S4 is corrected to 0;
2) and when the fatigue state monitoring device monitors that the same driver continuously drives for more than a fourth preset time length N, wherein N is greater than M.
Specifically, the second trigger condition is a mandatory trigger condition, when the H value is corrected to 0, that is, the driver enters a fatigue driving state at the moment, the parking air conditioner needs to immediately switch to a warning mode, so that the driver is enabled to be kept awake by force; or even if the driver does not enter the fatigue driving state currently, based on a conservative strategy and due to compliance with a cross rule, namely when the same driver continuously drives for more than a fourth preset time length N, the parking air conditioner immediately shifts to a warning mode, so that the driver is subjected to commoditing for receiving salutation from cold wind blowing face, wherein the preset value of N can be equal to 4 hours, or fluctuates to a certain extent around 4 hours, and N is preferably more than 1.5M.
Preferably, the alert mode includes a light alert mode, a medium alert mode and a heavy alert mode, and correspondingly, the cold air level face blowing mode also includes a low level, a medium level and a high level, and the cold air blowing temperature and/or the first preset time length X of each level are gradually decreased along with the automatic switching from the low level to the high level.
Specifically, after entering the alert mode, that is, corresponding to the determination result of the driving state in step S1 being the fatigue driving state or being forcibly assumed to be the fatigue driving state, the fatigue degree of the fatigue driving state may be further subdivided, and for example, the driving state may be determined as a light fatigue state, a medium fatigue state, or a heavy fatigue state according to the difference in the fatigue degree. And through the further hierarchical setting of the alert mode, when the parking air conditioner enables a driver to be kept awake by force, the parking air conditioner can feed back alert responses of different levels according to different current fatigue degrees of the driver, and specifically can show that the cold air face blowing temperature is gradually decreased step by step and/or the cold air face blowing frequency is gradually increased step by step so as to ensure that the current gear of the cold air face blowing mode is matched with the current fatigue degree, and therefore excessive alert cannot be generated. For example, the value of the first preset time period X may be a decreasing value (10, 5, 2), or may be a fixed value 5, where the unit is minutes, and the values correspond to the low, medium, and high cold air gear face blowing modes, respectively, and the duration T may be 5 seconds or 10 seconds.
Preferably, when the parking air conditioner automatically shifts to any one of the warning modes, the vehicle-mounted voice unit gives a broadcast prompt in a voice broadcast mode, wherein at least in the severe warning mode, the broadcast prompt content contains navigation information of a nearby parking lot or service area.
Specifically, as one preferred implementation manner of this embodiment, the broadcast prompting content may be that, for example, a "moderate warning mode for parking air conditioner is turned on, an XX service area three kilometers away from the XX service area is recommended for you to please confirm going", after the confirmation information that the driver confirms going is obtained, the vehicle-mounted GPS unit automatically navigates to the service area, so that the trouble that the driver needs to manually navigate to find a parking lot or a service area to temporarily change the driving destination is avoided when he is tired and in panic, and particularly on a highway at night, the embarrassment that the driver cannot fall back because he accidentally misses the next service area without navigation is avoided. Furthermore, the vehicle-mounted voice unit has an interactive function, so that the driver can perform positive confirmation or further interaction of the information through voice interaction, and of course, the driver can also choose to ignore or perform refusal confirmation.
It should be noted that, as another preferred embodiment of this embodiment, at least in the heavy warning mode, the broadcast reminding content may directly start the navigation to the new destination without including the confirmation instruction information, for example, the broadcast reminding content may also be "the parking air conditioner heavy warning mode is started, the destination has been forcibly changed by the vehicle-mounted GPS unit for your purpose, the destination is the XX service area three kilometers away from the previous destination, and please go into the XX route by turning left after keeping going straight one kilometer".
Preferably, the urge and/or the restitution times of the voice broadcast are gradually increased along with the gradual increase of the vigilance mode.
Specifically, the urge sense and/or the repeating frequency of voice broadcast are adapted to the fatigue degree in the fatigue driving state, and the urge sense and the audio-visual quality of the driver can be enhanced step by step according to the difference of the current fatigue degree.
Finally, it should be noted that, as a complement to the park air conditioner comfort mode and/or the vigilance mode, the park air conditioner may also issue a command call to other on-board units to further enhance the comfort and/or the vigilance of the driver. For example, in a comfort mode, the parking air conditioner can also initiate instruction calling for the roof lamp so as to automatically adjust the brightness and softness of the roof lamp; or initiating instruction calling for the vehicle-mounted entertainment system to automatically recommend and play soft music; or initiate a command call to the backrest seat with the massage function, and the like, which are beneficial to further enhancing the comfort of the driver. In a warning mode, for example, the parking air conditioner can also initiate instruction calling of an audible and visual alarm system so as to further enhance the warning degree of a driver and send fatigue alarm signals to surrounding vehicles and even a warning platform.
Example 2
The present embodiment is a further optimization made on the basis of embodiment 1 for the control method.
As also shown in fig. 1, when the parking air conditioner is automatically shifted to any one of the alert modes, its automatic shifting manner is: under the operation of the warning mode, after the cold air gear face blowing mode of each time is finished, the fatigue state monitoring device carries out a new round of judgment on the improvement degree of the judgment based on the fatigue driving state of the previous round every a second preset time length Y so as to determine a new round of driving state, and the parking air conditioner rectifies and executes the deviation to the operation mode matched with the parking air conditioner according to the new round of driving state, wherein Y is 1/2X.
Specifically, after entering the alert mode, the driving fatigue state of the previous round can be further subdivided into three states of light fatigue, moderate fatigue and heavy fatigue, or a fourth state, that is: mild fatigue is assumed. In the alert mode operation, although a considerable portion of the drivers may be allowed to subjectively and actively take a stop and a rest even in any driving state, in view of the fact that in the alert mode, including the driver navigating to the nearest parking lot or service area, the current driving state of the driver may be changed relatively sharply before and after the cold air blowing mode is completed for each time, it is preferable to perform a new round of timing determination of the degree of improvement when Y is 1/2X, so that the strong waking effect of the cold air blowing mode for each time can be more objectively checked, and the continuation of the parking air conditioning operation mode can be corrected. For example, when a new determination is made on the degree of improvement of the determination based on the previous cycle of the fatigue driving state, the determination results can be classified into the following three types: the fatigue degree is improved, maintained and increased, so that the three and/or four fatigue driving states are timely corrected, the parking air conditioner is timely adjusted to the running mode matched with the latest correction result according to the correction result, and excessive or insufficient warning cannot be generated.
It is understood by those skilled in the art that if the parking air conditioner automatically shifts from the comfort mode to the light warning mode, the determination of the previous fatigue driving state is "light fatigue" or "assumed light fatigue", but it should be noted here that, for the "assumed light fatigue" state, as long as the driving process occurs once and the fatigue state monitoring device does not monitor the driver replacement, or the state is changed again after the replacement within a short time, such as half an hour, that the continuous deviation correction of the state is not decreased or a lower limit of the reduction amplitude is set, for example, "assumed light fatigue" is corrected to be medium fatigue after one determination, and when the driving process is performed again, even if the fatigue degree is improved, the state is maintained to be medium fatigue or "assumed light fatigue", rather than light fatigue, "assumed light fatigue" is used as the lower limit of the reduction amplitude, even if the latest round of fatigue improvement determination is made again, the deviation is not corrected to, for example, "pseudo-healthy driving state", so that the parking air conditioner is prevented from being reversed back to the relaxing mode. That is, only after the light fatigue is improved by one round of fatigue, the step S5 can return to the step S4 again, and the parking air conditioner can continue to maintain the correction of the H value and the voice broadcast or the display of the display number. For the convenience of those skilled in the art to understand, it may be referred to simply as meeting specific conditions, and refer to fig. 1 in detail.
Therefore, for a part of drivers with good restoring force, as long as the accumulated continuous driving time (without the time occupied by replacing the driver in a short time midway) in the driving process does not exceed the fourth preset time N, the drivers can still continue to enjoy the pseudo-healthy driving state in the relieving mode, so that the problem that a part of drivers have to continue to drive a small section of mileage and have to bear the embarrassment of blowing cold face forcibly due to the urgent situation in reality is solved. If the fatigue state monitoring device monitors that the driver is replaced and keeps the driving state for a certain time in the driving process, the warning mode of the parking air conditioner can be automatically released and switched to the relieving mode, and then the driver can select to turn off the relieving mode when the forced triggering condition in the first triggering condition is not met in the relieving mode.
Preferably, when the parking air conditioner is firstly switched into the heavy warning mode, the vehicle brake unit takes a mandatory braking measure and automatically drives to a nearby parking lot or service area according to mandatory navigation of the vehicle-mounted GPS unit.
It is undeniable that after the series of anti-fatigue measures, a small part of drivers still have high risks and choose to continue fatigue driving, and when the parking air conditioner is switched into a severe caution mode for the first time, if the drivers still do not drive according to the navigation route automatically and forcibly replaced by the vehicle-mounted GPS unit, the danger degree corresponding to the drivers continuing to drive manually is very high, and the drivers adopt the forcible braking measures to automatically drive to a nearby parking lot or service area, so that the danger factors can be greatly reduced and ended. In the process, the parking air conditioner can continuously keep the heavy warning mode until the parking air conditioner safely reaches a nearby parking lot or a nearby service area, the vehicle automatically extinguishes, the heavy warning mode is not released, and preferably, the vehicle brake unit is automatically locked for a fifth preset time after the vehicle automatically extinguishes. It should be noted that, if the driver needs to change the air conditioner, the driver must take full care of the driver's urgent situation before the air conditioner is switched to the heavy warning mode for the first time, so that the psychological expectation of the driver can be further clarified, and the driver luck psychology can be reduced.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
