Sailing reaction under state can slow up, and action can become sluggish, this is mainly presented with the following aspects in behavior：1. because of note
Meaning power, which is not concentrated, leads to braking moment, that is, the moment of slowing down is partially late；2. because braking moment is partially late, braking can be caused to subtract to avoid collision
Speed is bigger than normal, i.e., deceleration is bigger than normal.So, two threshold values are set, is moment threshold value T and deceleration threshold A respectively, works as difference
When t1-t0 is more than moment threshold value T, indicates that driver's deceleration moment is partially late, count once, also, later whenever satisfaction：Difference
T1-t0 is just counted once more than moment threshold value T hour counter, and accumulative is counted as m；When difference a1-a0 is more than deceleration threshold A
When, it indicates that braking deceleration is bigger than normal, counts once, later whenever satisfaction：Difference t1-t0 is more than moment threshold value T hour counter just
It counts once, accumulative is counted as n.
May determine that driver after certain number occurs in the above behavior, currently there is no be in a good driving shape
State, i.e., when m and n's and value more than setting number threshold value N when, system is finally determined as that driver is in fatigue driving state.
Wherein, number threshold value N requires to be set according to control, such as：When N is equal to 1, as long as indicating to occur primary：Difference t1-t0
More than moment threshold value T, or occur primary：Difference a1-a0 is judged as fatigue driving more than the case where deceleration threshold A, institute

Table 1
Remember that the steering wheel angle size of driver's practical operation is second direction disk rotational angle theta 1, note driver's practical operation
Direction disk rotating speed size is second direction disk rotating speed ω 1, compares second direction disk rotational angle theta 1 and first direction disk rotational angle theta 0, and
Second direction disk rotating speed ω 1 and first direction disk rotating speed ω 0, and calculate second direction disk rotational angle theta 1 and first direction disk rotational angle theta 0
Error amount, the present embodiment is the error of difference θ 1- θ 0 and second direction disk rotating speed ω 1 and first direction disk rotating speed ω 0
Value, the present embodiment are difference ω 1- ω 0.Driver is also presented with the following aspects under fatigue driving state in behavior：
The positive speed of steering wheel return is slow when 1. vehicle has just begun to deviate from track, return positive-angle and speed it is less than normal, i.e., steering wheel angle and turn
Speed is less than normal, and vehicle can slowly deviate from track first；After 2. vehicle deviates from certain distance, driver can again with one substantially
The action of degree, which is returned, to be come, and causes steering wheel angle and rotating speed in this short time bigger than normal.So, two threshold values are set, point
It is not steering wheel rotary speed threshold value θ and steering wheel rotary speed threshold value ω, when the absolute value of difference θ 1- θ 0 is more than steering wheel rotary speed threshold value θ
When, that is, work as | θ 1- θ 0 |>When θ, indicates that steering wheel angle deviation is larger, count once, also, later whenever satisfaction：|θ1-θ0|>
θ hour counters just count once, and accumulative is counted as p；When the absolute value of difference ω 1- ω 0 is more than steering wheel rotary speed threshold value ω
When, i.e., | ω 1- ω 0 |>When ω, indicates that direction disk rotating speed deviation is larger, count once, also, later whenever satisfaction：|ω1-ω
0|>ω hour counters just count once, and accumulative is counted as q.
May determine that driver after certain number occurs in the above behavior, currently there is no be in a good driving shape
State, i.e., when m, n, p and q and value be more than number threshold value N when, system is finally determined as that driver is in fatigue driving state.With
Above-described embodiment 1 is identical, and number threshold value N is also to require to be set according to control, and N can be equal to 1, can also be more than or equal to 2,
When N is equal to 1, Stringency highest is judged, safety also correspondingly highest, still, such case cannot exclude the feelings of erroneous judgement
Condition, the possibility for occurring judging by accident are higher；The numerical value of N is bigger, judges that Stringency is lower, and safety is also correspondingly lower, still,
Correspondingly, the possibility of erroneous judgement is also reduced.

There is active operation vehicle active steering or lane change just occur, therefore, can be judged by detecting steering controling signal
Whether active steering or lane change, then, active steering detection module can control bar state for detecting steering indicating light to set
It is standby, can also be the equipment for detecting turn signal state, in the present embodiment, active steering detection module is to turn to lamp controller, is driven
When the person's of sailing active steering, steering indicating light control-rod is operated, operation signal is exported to lamp controller is turned to, turned to by steering indicating light control-rod
Lamp controller just controls the steering indicating light flicker of respective side, therefore can be judged according to the control signal for turning to lamp controller output
Go out driver whether active steering or lane change, then, turn to lamp controller signal is exported to controller by CAN bus,
Controller obtain vehicle turn signal whether open, and then judge driver whether active steering or lane change.
Controller, which receives, turns to the signal sent of lamp controller, be determined as after steering indicating light unlatching driver's active steering or
Person's lane change, steering wheel angle and rotating speed may be bigger than normal at this time, in order to avoid judging by accident, stopping counting p and q during this,
Even if meeting corresponding Rule of judgment, will not count, p and q will not be from adding 1, and such case maintains to close until steering indicating light,
I.e. until active steering or lane change terminate.So, after active steering or lane change, the counting of p and q restore normal.
