3) judge whether the continuous driving time of single and the same day accumulative driving time that added up have reached fatigue driving
Standard；If the not up to standard of fatigue driving, return to step 2) continue computing；If it is not 0 to analyze the last item speed
Data, then judge all running datas on the computing complete same day.
Described speed is extracted by the OBD system of vehicle and gathered.
Step 2) judge vehicle whether in continuously driving whether the condition of state surpasses for the time difference of adjacent two data
Cross 2s.
Described step 2) in：
The actual continuous driving time=single of single continuous driving time+time difference；
The actual same day adds up accumulative driving time+time difference on driving time=same day.
The step 2) in if the time difference is more than 20 minutes, then judge that driver meets the parking time of having a rest and require, will be single
Secondary continuous driving time is set to 0.The step 2) in if the same day add up driving time be more than 8 hours, then judge driver add up
Fatigue driving, accumulated fatigue drives number of times and is set to 1.
Compared with prior art, the present invention has following beneficial effect：Whether it is 0 according to speed information, by vehicle shape
State is divided into transport condition and dead ship condition, determines running time and down time, first by daily single fatigue driving
Number of times, the accumulative number of times, the same day of driving add up driving time and the continuous driving time initialization of single, are arranged in the running time of vehicle
The time difference of adjacent two data is calculated in table, continuous driving time is added up according to the size of time difference.Final basis is continuously driven
The time of sailing judge vehicle whether fatigue driving and fatigue driving type.The present invention can evaluate truck man in driving procedure
Whether meet road safety standard, i.e. 24 hours accumulative driving times of driver to be no more than in principle 8 hours, it is continuous in the daytime to drive

Brief description of the drawings
The control algolithm flow chart of Fig. 1 present invention；
The postrun result exemplary plot of Fig. 2 inventive algorithms；
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
According to《Opinion of the State Council on strengthening traffic safety work》Point out, it should be ensured that driver tires out for 24 hours
Count driving time to be no more than in principle 8 hours, continuous in the daytime to drive no more than 4 hours, night continuously drives and is no more than 2 hours.
According to this principle, the fatigue warning for defining continuous drive less than 8 hours more than 4 hours of driver and not resting enough 20 minutes is " single
Secondary fatigue driving alarm ", it is " accumulative fatigue driving alarm " that the fatigue warning of more than 8 hours is driven on the day of defining driver.
According to vehicle is divided into running time and dwell time in the speed information gathered from OBD in car, running time is
The time that the speed of vehicle is not zero, down time be vehicle speed be zero time.If driver continuously drives 4 hours,
Period, which does not stop, rests enough 20 minutes, then illustrates driver's single fatigue driving, the single fatigue driving number of times on the same day adds 1；Such as
Accumulative driving time then illustrated that driver added up fatigue driving, accumulated fatigue drives number of times and is set to more than 8 hours on the day of fruit driver
1。
Referring to Fig. 1-2, fatigue driving determination methods of the present invention specifically include following steps：
1) single fatigue driving number of times, accumulative fatigue driving number of times, the same day are added up driving time by algorithm at first
And the continuous driving time of single is all set to 0.
2) because the vehicle speed data of one day is counted always from the zero point on the same day to the zero point of second day, in this phase
Between existing running time also have down time.Each speed information is analyzed, judges whether it is more than 0, if greater than 0, explanation
Vehicle is in transport condition, and this speed and time are deposited into running time list；If speed information is equal to 0, say
Bright vehicle is in dead ship condition, and this speed and time are deposited into down time list.
3) in motion between time difference of adjacent two data is calculated in list, if vehicle is in the state continuously driven
Then the adjacent two datas time difference is generally 2 seconds, and if vehicle, adjacent two speeds are not zero if having parking during travelling
Data time difference is the down time of vehicle.
4) judgment step 3) in time difference of adjacent two data for trying to achieve, if the time difference be less than 20 minutes, explanation department
Machine is without parking rest enough 20 minutes or simply temporary parking according to the rules, then accumulative to the continuous driving time of single and the same day
Driving time is added up.Continuous driving time=the single of single continuous driving time+time difference；The same day add up driving time=
The same day adds up driving time+time difference.If the time difference is more than 20 minutes, illustrate driver according to fixed parking rest enough 20
Minute, then the continuous driving time of single is set to 0.
5) judgment step 4) in the continuous driving time of single that added up and the same day add up driving time whether reach it is tired
Please the standard sailed.If the continuous driving time of single is more than 4 hours, illustrates that driver continuously drives and do not rest for 4 hours,
Then single fatigue driving number of times is accumulated once, and the continuous driving time of single is set to zero.If it is small more than 8 that the same day adds up driving time
When, illustrate that this day of driver has driven 8 hours, then accumulative fatigue driving number of times is set to 1.
(6) if step 5) in be not reaching to the standard of fatigue driving, return to step 3) start to continue computing.Such as simultaneously
