Description
Technical field
The invention belongs to fatigue driving monitoring technical fields, and in particular to a kind of anti-fatigue-driving system and its controlling party
Method.
Background technique
In vehicle travel process, driver will appear fatigue because of reasons such as living environment, summer driving and high speed travelings
Drive, and fatigue driving be cause traffic accident an important factor for one of.
Eye Recognition use at present it is more universal, be common in vehicle shown by instrument or HU system using icon or
Instrument buzzer prompts user, and user is prompted to pay attention to itself fatigue state, pays attention to parking rest.But current Eye Recognition exists
Prompt in vehicle application has little effect, and for human fatigue driving status without progressive response, correlation prompt is easily by driver
Ignore, also there is no the outer prompt facility of vehicle, the effect that stimulation is not achieved and driver and other driver safeties is protected to drive.
Therefore, it is necessary to develop a kind of anti-fatigue-driving system and its control method.
Summary of the invention
The object of the present invention is to provide a kind of anti-fatigue-driving system and its control methods, can be directed to driver fatigue shape
State realizes that vehicle window automatically controls, realizes external lights warning note, realizes the progressive alarm of entertainment systems, reaches stimulation and guarantor
Protect the effect of driver and the driving of other driver safeties.
Anti-fatigue-driving system of the present invention, including IP（Instrument）, camera shooting ECU（Camera controller）,HU（That is vehicle
Carry entertainment systems）And BCM（Car body controller）；
The camera shooting ECU infers driver status according to driver's face of acquisition and eye feature, and by driver status
Information is sent to vehicle CAN network；
The IP obtains speed signal from vehicle CAN network, and by current vehicle speed and default uplink speed threshold value and default downlink
Speed threshold values is compared, and judging result is sent to IP, HU and BCM；
After BCM receives driver status signal, and it is higher than default uplink speed threshold value in current vehicle speed, and driver status is tired
When please sailing, BCM controls vehicle emergent alarm lamp and interior emergent alarm lamp flashing, and controls main window decline of driving；
After HU is according to driver status signal, and it is higher than default uplink speed threshold value in current vehicle speed, and driver status is tired
When please sailing, HU carries out first run warning in a manner of video and/or audio, after first run warning, if not taking shut-down operation,
HU carries out two wheel warnings in a manner of video and/or audio again, and does not take shut-down operation yet after two wheel warnings, then automatic to adjust
The volume of radio and/or music actuator is saved to maximum.
Further, when system judges to manually control vehicle window behavior or IP judge current vehicle speed be less than set in advance
When fast threshold value of driving a vehicle, control of the system closure BCM to main window of driving.
Further, when system judges to manually control emergency button or IP judge current vehicle speed be less than set in advance
When fast threshold value of driving a vehicle, the control of system closure vehicle emergent alarm lamp and interior emergent alarm lamp.
Further, when system judges to manually control HU behavior or IP judges that current vehicle speed is less than default downlink
When speed threshold value, system closure HU carries out warning note.
Anti-fatigue-driving control method when of the invention, using anti-fatigue-driving system of the present invention, method packet
Include following steps：
The first step：Vehicle launch；
Second step：IP determines whether vehicle speed is higher than default starting speed threshold value, if so, activation system, and enter third
Step, if it is not, then continuing second step circulation；
Third step：IP determines whether vehicle speed is higher than default uplink speed threshold value, if so, into the 4th step, if it is not, then holding
Continuous third step circulation；
4th step：Judge whether in fatigue driving, if it is not, then continuing the 4th step circulation, if so, into the 5th step；
5th step：The main window decline of driving of BCM control, vehicle emergent alarm lamp and interior emergent alarm lamp flashing；
HU judges whether to be reminded for the first time simultaneously, if so, HU carries out period warning by audio and/or video, and in police
Self-navigation shows neighbouring break point after the completion of showing；
After HU carries out a wheel prompting, being such as not carried out shut-down operation, then HC carries out secondary warning by audio and/or video, if
It is still not carried out shut-down operation after two-wheeled warning, then automatically adjusts the volume of radio and/or music actuator to maximum.
Further, in the 5th step, when the main window of driving of BCM control declines；
When system judges to manually control vehicle window behavior or IP judges that current vehicle speed is less than default downlink speed threshold value

Further, in the 5th step, during HU is executed and is warned；
When system judges to manually control HU behavior or when IP judges that current vehicle speed is less than default downlink speed threshold value,
System closure HU carries out warning note.
Further, in the 5th step, when HU is for the first time to warn, is slowed down by voice reminder user and rested, and pass through figure
Piece display reminding user, which is stopped, to rest.
Further, in the 5th step, when HU is two wheel warnings, by playing fatigue driving traffic accident video and audio, and
Being played by voice influences caused by traffic accident accident.
The present invention has the following advantages that：For driver fatigue state, combine using vehicle electric system and cooperate, realizes vehicle
Window automatically controls, realizes the prompt of inside and outside light warning, realizes the progressive alarm of entertainment systems, reaches stimulation and protection driver
And the effect that other driver safeties drive.
