Specific embodiment：
As shown in figure 1, this specific embodiment is employed the following technical solutions：It includes pilot's line of vision detection means 1, car
State acquisition unit 2, driver's point of fixation detection module 3, front windshield screen trigger module 4, front windshield screen
Display location judge module 5 and front windshield screen exit module 6, and pilot's line of vision detection means 1 and vehicle-state are gathered
Unit 2 is connected respectively with front windshield screen trigger module 4, front windshield screen trigger module 4 and front windshield screen
One end connection of curtain display location judge module 5, the other end and front windshield of front windshield screen display location judge module 5
Glass screen exits module 6 and connects.
Preferably, described pilot's line of vision detection means 1 is eye tracker, described pilot's line of vision detection means 1
In include the person's of sailing point of fixation detection module 3.
The operation principle of this specific embodiment is：Pilot's line of vision detection means 1 refers mainly to eye tracker, and eye tracker is utilized
Photographic head shoots the eyes of driver, and by the position of driver's pupil of both eyes in analysis video, finds out the friendship of eyes sight line
Point is the point of fixation of driver.Driver's point of fixation detection module 3 in eye tracker can real-time detection go out the note of driver
Viewpoint, and the position of point of fixation is exported, use for subsequent analysis.During driver drives, driver's point of fixation
Detection module is continual to the point of fixation of driver to carry out real-time detection, and testing result is sent to front windshield screen
Trigger module 4.
Driver's point of fixation toggle area is set at front windshield, when driver watches the region attentively more than 5 seconds are reached
When, then the trigger message is sent to front windshield screen trigger module 4.Think if the time that driver watches attentively reaches 5
Second and more than, illustrate that driver has enough free times to watch the content of screen, normally drive without having influence on.Note
Viewed area should select the boundary in front windshield, positioned at driver's normal driving when the region seldom watched.
When driver watched the time of toggle area attentively more than 5 seconds, by the CAN acquisition speed sensor of automobile,
The running state information of the vehicle that acceleration transducer etc. is collected, the running state information of vehicle includes the speed of vehicle and adds
Speed, and the data that collection comes are sent in real time front windshield screen trigger module 4.
Front windshield trigger module 4 is used to carrying out the running state information for watching information and vehicle attentively of driver point
Analysis, and decide whether to trigger screen.Specifically triggering analysis process is：First, if the triggering of front windshield screen
Module 4 receives the information that driver's point of fixation detection module 3 sends, if the information refers in particular to driver watches toggle area attentively
Time reach 5 seconds and more than, driver's point of fixation detection module 3 just to front windshield screen trigger module 4 send triggering
Information.Front windshield screen trigger module 4 is received after the information, i.e., the running state information of vehicle is analyzed.Such as
Fruit vehicle is in high-speed travel state, or is in acceleration mode, then cannot trigger screen；If the speed of vehicle is less than
The speed of 30km/h or vehicle is 0, and (acceleration is less than 3m/s without significantly accelerated trend2), then open screen.Specifically
Analysis process it is as shown in Figure 2.
Front windshield screen trigger module 5 watches the running state information of information and vehicle attentively to screen according to driver
After being opened, need to judge screen display location.Specific determination methods are the method for neutral net, in screen
Incidence relation is set up between position and the content of display so that when driver wants to watch different contents, only sight line need to be moved
To related position.Because neutral net has the ability of self study, therefore this method can be according to different drivers'
Difference custom and hobby change the position of screen and the relation of content.
A () obtains training sample set
First front windshield is uniformly divided into into 9 regions, the point of fixation of driver falls in difference within the unit interval
Time in region can be come out with eye tracker, while driver is look at, inquiry driver is wanted in this region
The content inside seen, such as map, entertainment information, fileinfo.Driver repeatedly after viewing, records the region of driver's viewing
With it is corresponding wish viewing content and recorded, just obtained one group of training sample set.
Hypothesis has P training sample set, that is, have P inputoutput pair, (Ip, Tp), p=1 ..., P.
Wherein, input vector is Ip=(ip1..., ipm)T, actual target output vector is Tp=(tp1..., tpn)T, reason
It is O by output vectorp=(op1..., opn)T。
(b) neural net model establishing
According to the analysis to this method, the neural network model belongs to the simple network without intermediate layer, its model such as Fig. 3
It is shown.
(c) knowledge learning process
Note wij be from the jth of input vector (j=1 ..., m) individual component to output vector i-th (i=1 ..., n) individual point
The weight of amount.Generally theoretical value has an error with actual value, and knowledge learning then refers to and constantly theoretical value is compared with actual value,
And parameter wij is changed according to minimum principle, error sum of squares is made up to minimum：
Use Δ wijRecursion modification amount once is represented, is then had,
Wherein η is learning rate.
Weights are determined by knowledge learning process, you can determine the functional relationship between input quantity and output,
Can determine that driver wants the content seen according to the position of driver's point of fixation.Can enter in driver's point of fixation region
The broadcasting of row screen content.
For different drivers, the custom and hobby of its viewing is different, can be to the point of fixation of each driver
It is trained with the content of the screen for wanting to watch, you can obtain the screen display mode of personalization.
If driver wants to exit out screen watching mode, screen toggle area can be watched attentively, fixation time reaches 5 seconds
When clock and the above, screen is just automatically exited from.
It should be noted that when front windshield screen shows, front windshield screen trigger module is not yet
The state of disconnected detection vehicle, if the speed of vehicle is beyond 30km/h, or the acceleration of vehicle has exceeded 3m/s2, then
Stop screen display at once.
Ultimate principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply illustrate principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within the range of claimed this utility model.This utility model
Claimed scope is by appending claims and its equivalent thereof.
