Description
Technical field
The present invention relates to vehicle anti-misoperation system；Specifically a kind of portable anti-error driving GPS navigator.
Background technology
Driver when driving, can occur unnumbered contradiction with other vehicles, pedestrian, and driver must be timely
It was found that, rapid to judge, reasonable operation just can ensure that the smooth and safe of driving.Driver is sitting in fixed for a long time
On seat, action is subject to a definite limitation, is busy with judging in-car external stimulus information, state of mind high-pressure, easily
Cause fatigue.So-called fatigue driving, refer to driver in driving, because driving operation makes physiologically or psychologically
There is certain change, and objectively occurring driving the low phenomenon of function.The fatigue that either physiological reason is produced
Or the fatigue or both that psychological causes is produced combines the fatigue for producing, and can all make driver's physically-draining, notes
Power is not concentrated, the dimness of vision, slow in reacting, be out of one's reckoning, and drives dumb, misoperation etc., drives length
Time fatigue may finally cause can not in time find dangerous situation, and delay is taken the opportunity of measures to keep clear, final hair
Raw traffic accident.There is the even sleepy drowsiness of driver, vehicle is out of hand, just like " unmanned ", its consequence can
Think and know.
In recent years due to the improvement of people's living standards, vehicle guaranteeding organic quantity is also in sustainable growth.The thing followed is
Fresh driver rolls up, and the driving ability level of driver is very different, various bizarre and motley traffic accidents
It is to emerge in an endless stream, end of appearing in the newspapers frequently.
What wherein people were impressive is exactly that driving crashes into korneforos, crashes into marine, also drives to be dropped to from winding road
Accident under cliff.It is seen that these news can feel inconceivable, people how can it is muddled so far
Actually this no wonder, some roads are road conditions or coastal road conditions, also some winding road conditions, these roads along the river
Condition is in fact abnormally dangerous, because the side in track is exactly often the water surface or steep cliff, many road conditions are again without good
Quarantine measures, as long as steering wheel is misplayed direction in this road conditions, it is only necessary to short several seconds, just occur it is overboard or
Fall the accident of the car crash on precipice.
Mistake during driver drives drives reason a lot, wherein tired and absent minded and then generation misses driving being
The statistics of a key factor of traffic accident, Japan is triggered to show, the mistake that fatigue is produced drives accident and accounts for
Total 1~1.5%.Police general administration of French country accident report shows that the traffic accident occurred by fatigue doze accounts for personal wound
The 14.9% of evil accident, accounts for the 20.6% of death by accident.According to the ASSOCIATE STATISTICS of national communication department, fatigue driving
The traffic accident for causing accounts for total 20% or so of number, accounts for more than the 40% of especially big traffic accident.Drive by mistake absolute
It is number one killer, death and the disability of hundreds of thousands of them is caused every year, be that countless families bring great pain, causes huge
Big economic loss.Current fatigue detection method and evaluation meanses are more complicated due to actual environment, it is difficult to meet reality
The need for border, both at home and abroad to the fatigue driving detection of driver and warning device also in laboratory stage.Except this it
Outward, it is also the reason for causing maloperation mobile phone to be taken when driving, eaten, chatted, operating mobile unit etc..But
Whether because fatigue driving is also because other reasonses, miss driving behavior all great threat traffic safeties.
Existing fatigue driving detection is directed to driver's face eye feature, the detection of abnormal behaviour mostly, with reference to
The method of machine learning is judged, because the fatigue driving detection of such method needs to gather mass data, and not
The same various driving habits of driver have relatively large deviation, therefore this class method stills need to change in real-time with accuracy
Enter.
Existing driver fatigue detection technique is based primarily upon detection face technology, from driver's unique characteristics,
The physiological parameter feature or visual signature of driver are obtained by certain equipment, using driver in normal condition and
The feature mode of fatigue state is different, is differentiated using the classification of corresponding mode identification technology, is so as to detect
It is no to have tired generation.Due to needing to carry out real-time detection track human faces feature using DSP, therefore hardware cost is higher,
And some drivers not can be by fatigue state reflection to face, therefore system accuracy is not high.
Because whether tired the method for detection driver at present be also immature, and detection means is affected by environment larger,
Equipment cost is high, it is difficult to meet be actually needed.Therefore in the urgent need to one kind can be when driving behavior by mistake occurs in driver
Prompting driver, or the system and method that limitation misses driving behavior in time.
The content of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, abandons existing fatigue detecting, is carried
For a kind of portable anti-error driving GPS navigation that a kind of energy is directly alarmed when driving behavior by mistake occurs in driver
Instrument.Sharp cartographic information and in real time positioning, it is determined that dangerous direction, and in wheel steering Times consistent with dangerous direction
It is alert.
