Description
Technical field
The present invention relates to the technical field of vehicle-mounted pick-up imaging, specially a kind of method for improving safe driving.
Background technique
In reality it is noted that due to driver tired driving, some accidents are caused.Driver is continuous for a long time
After driving, the imbalance of physiological function and mental function is generated, and the phenomenon that driving efficiency decline is objectively occurring.Driver sleeps
It sleeps of poor quality or insufficient, long-duration driving vehicle is easy to appear fatigue.Driving fatigue influence whether the attention of driver, feeling,
The aspects such as consciousness, thinking, judgement, will, decision and movement.Continue to drive vehicle after fatigue, can feel sleepy drowsiness, four limbs
It is powerless, absent minded, judgement decline, or even the memory of absent-minded or moment occur and disappear, appearance movement delay or
Too early, operation pause or correction time improper equal insecurity factors, easily generation road traffic accident.
Fatigue driving causes very big harm to driver itself and nearby vehicle, and depot, traffic administration part are to effective
This danger is reduced, cry is increasing.Fatigue driving solves technology and also just comes into being.
It is existing for monitor driver whether the method for fatigue driving, be by camera monitor in real time driver face
Portion's feature, eye signal, head movement, then infer the fatigue state of driver by built-in analysis system, and carry out
Warning note and corresponding measure is taken, only driver can be prompted to need to rest, surrounding vehicles cannot be reminded in time to pay attention to pacifying
Entirely, pro-active intervention can not be made when driver is in driving dangerousness state.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of method for improving safe driving, it is real-time by heartbeat sensors
The driving condition for judging driver, according to the state of driver, gradient type, which is made, is passively or actively reaction, it is ensured that safe driving.
A method of improving safe driving, it is characterised in that: it is placed with non-contact type milli immediately ahead of driver
Metric wave heartbeat sensors, the driving condition of non-contact type millimeter wave heartbeat sensors real-time judge driver, according to driving meter
Driving condition, security system gradient type give a response；When driver status is safe, carry out continuing monitoring, security system not
It does and actively responds；When driver status is dangerous, security system is according to the seriousness of unsafe driving state, to periphery vehicle
Transmit danger reporting, and the gradient type pro-active intervention to this vehicle including sounding an alarm, forcing parking, emergency braking.
It is further characterized by
Non-contact type millimeter wave heartbeat sensors judge the state of driver, including fatigue, sleepiness, attention according to heartbeat
When the state of reduction, with include sound, alarm, vibration alerting pattern remind driver to take care driving, when driver still
When old lasting above-mentioned unsafe driving state, the vehicle of driver driven is carried out continuing to drive alerting and sounding an alarm,
When unsafe driving state rises to precarious position, security system shares the state of the driver, to nearby vehicle sending pair
It dodges warning and actively forces pulling over observing；
When non-contact type millimeter wave heartbeat sensors judge that driver is under certain danger state according to heartbeat, safety is
System to nearby vehicle issue it is double dodge warning, active emergency braking, while by the state tying of vehicle driver to surrounding homologous ray
Vehicle, and first time alert process；
Non-contact type millimeter wave heartbeat sensors using millimetre-wave radar electromagnetic signals, encounter barrier reflection,
The signal that radar system is reflected by capture, to determine the distance of object, the millimeter wave of non-contact type millimeter wave heartbeat sensors
System works in 76-81GHz, and wavelength is about 4mm, has the ability for detecting the small object to millimeter, non-contact type millimeter wave
Heartbeat sensors, to the distance of torso model, to determine the heartbeat data of driver, and then pass through safety by detection sensor
It is in safe driving state or unsafe driving state, while according to unsafe driving state that network analysis, which goes out driver,
Seriousness, be divided into the driving shape that only abnormality, driver's physical fatigue driving condition, driver are in the hole
State；
Security system persistently makes somebody a mere figurehead driver in safe driving state, homologous ray vehicle is shared driver safety and driven to around
Sail state；Security system takes action to driver and alerts, is simultaneously emitted by the driving of acousto-optic-electric alarm and reminding in driver's abnormality
Member shares the abnormality of driver to homologous ray vehicle around；Security system is in driver's physical fatigue driving condition to driving
Member carries out fatigue driving warning, while forcing to stop, and shares the driver status to homologous ray vehicle around, is simultaneously emitted by dangerous feelings
Condition notice；In driver's driving condition in the hole, the vehicle driven to driver carries out urgent security system
Braking, and the state of driver is shared to homologous ray vehicle around, is simultaneously emitted by dangerous situation notice.
After applying the present invention, the driving condition of non-contact type millimeter wave heartbeat sensors real-time judge driver, according to driving
The driving condition of meter is sailed, security system gradient type gives a response；When driver status is safe, carry out continuing monitoring, safety
System, which is not done, actively to be responded；When driver status is dangerous, security system according to the seriousness of unsafe driving state, to
Periphery vehicle transmits danger reporting, and actively dry to gradient type of this vehicle including sounding an alarm, forcing parking, emergency braking
In advance；It is by driving condition of heartbeat sensors real-time judge driver, according to the state of driver, gradient type make it is passive or
Active reaction, it is ensured that safe driving.
