It opens simultaneously and controls to adjust fragrant atmosphere device 700, negative ion gas generating device and refrigeration mode, to help to a certain extent
Driver restores waking state.
To sum up, the fatigue state of driver is perceived by camera sensing device, realizes intelligent unlatching gas generator, and
The gas for having functions of refreshing brain and restoring consciousness is released, driver's state of mind can be improved, does not need driver manually
Opening fragrant atmosphere device 700, negative ion generating device and/or oxygen generator, driver can get more humane user's body
It tests.
A feasible embodiment proposes a kind of for alleviating the intelligent vehicle-carried fragrant atmosphere system of driving fatigue in this specification
The working method of system, specifically, as shown in Figure 5.The heart rate value of driver is detected in the method using Intelligent heart rate steering wheel,
The driving condition of driver, and then intelligent control perfume (or spice) atmosphere system are judged again.
In the present embodiment, heart rate detection unit 202 is using Intelligent heart rate steering wheel, the Intelligent heart rate steering wheel
The heart rate value of real-time detection driver, and the heart rate value is transferred to data processing module 300.The heart rate value passes through data
After processing, it is transferred to feature comparison module 400, the feature comparison module 400 obtains phase according to preset fatigue characteristic data
Answer feature comparison result.It controls information generating module 500 and control information is generated according to the feature comparison result.
If there is abnormal, the generation of the control information generating module 500 heart rate abnormal signal in the heart rate value of driver, and
The heart rate abnormal signal is transferred to air-conditioner controller by CAN network.The air-conditioner controller passes through LIN network for institute again
It states heart rate abnormal signal and is transferred to fragrant atmosphere Setup Controller.
In response to the heart rate abnormal signal, fragrant atmosphere Setup Controller controls fragrant atmosphere device 700 and gives out peppermint, coffee etc.
Refresh oneself fragrance, driver is helped to alleviate driving fatigue, guarantees traffic safety.
It should be noted that in the present embodiment, only as an example with heart rate abnormal signal.Actual capabilities include more
Grade signal, that is, heart rate is divided into the grade of different urgency levels, the signal of generation also does corresponding classification processing, fragrant atmosphere system
System makes corresponding response further according to the signal received.
Driver in driving process, have always heart rate detection direction disk or safety belt monitoring driver heart rate,
In fatigue state, different variations can occur normal person for heart rate.When the heart rate value of driver is too low, lower than normal fluctuation model
It encloses, feature comparison module 400 judges that driver is in fatigue driving state, generates control when controlling information generating module 500
Information, and by the control information to vehicle CAN network；When air-conditioner controller receives the control information from CAN network
When, the control information can be sent to fragrant atmosphere Setup Controller by AC LIN network, fragrant atmosphere Setup Controller directly controls
Fragrant atmosphere device works, and distributes certain concentration and specific odor type, and driver is helped to recover from fatigue driving state,
To achieve the effect that ensure safe driving.
