User's drive routine behavior pattern in period, the preset time period may be configured as one week to 1 year, in the present embodiment
It may be configured as one month, the control processor 1 extracts the drive routine behavior pattern in user one month, i.e., user, which drives, practises
It is used, and store with the memory module 110, as a kind of extracting mode, the control processor 1 will acquisition for example：
Active user and the spacing of front truck（Continue）, lane change frequency, the condition overtaken other vehicles of selection（Follow-up time, quantity of overtaking other vehicles）.At control
Reason device 1 will judge whether user has driving exception according to user's drive routine behavior pattern of storage, if there is the second default ratio
It is abnormal will directly to judge that user drives during the difference of example threshold value.The second preset ratio threshold value may be configured as 20-70%, at this
40% is may be configured as in embodiment.
, will be to the export-restriction of speed control module 320 when the control processor 1 judges that user has driving abnormal
GES, the speed limitation module limitation vehicle are travelled with preset vehicle speed.The preset vehicle speed may be configured as 5-20km/h,
5km/h is may be configured as in the present embodiment.

Reason device 1 judges that user should not drive.The default blink threshold value may be configured as 10-20 beats/min, can be set in the present embodiment
For 15 beats/min, the control processor 1 is according to user's eye image statistics user's frequency of wink, when the frequency of wink of user
During higher than default 15 beats/min of threshold value of blink, it can determine whether that user should not drive.When the control processor 1 obtains user's eye
Image, when lacrimal secretion occurs in user's eye, the control processor 1 judges that user should not drive, as a kind of judgment mode,
Because human body eye moistens throughout the year, when there is lacrimal secretion, inferior orbit can be accumulated in at canthus, occurring moisture accumulation at two
When, the control processor 1 can determine whether user's lacrimal secretion.
Preferably, the memory module 110 is stored with user's pupil diameter under varying strength light, at the control
When reason device 1 judges that pupil diameter of the user under current intensity light is more than the pupil diameter threshold value under the intensitv light, institute
State control processor 1 and judge that user should not drive.Human body pupil under different light has corresponding scaling, when human body pupil has not
It is that human body exception occurs during normal reaction.The memory module 110 is stored with user's pupil diameter under varying strength light,
As a kind of data acquiring mode, it collects user's pupil image in a period of time and obtains current light intensity, described
A period of time can be one month.When the control processor 1 acquisition user's pupil image, and by under its light identical with storage
User's pupil is contrasted, and user's pupil under the current pupil of user is more than the identical light of storage, is as more than in the intensity
Through-hole diameter threshold value under light, then the control processor 1 can determine that user should not drive.
Preferably, opened when the control processor 1 judges that user should not drive to startup control module 310 output
Dynamic locking signal, while to the export-restriction GES of speed control module 320；If vehicle is not actuated, the startup
Control module 310 limits vehicle launch, conversely, being then failure to actuate；If vehicle has been turned on, the speed limitation module limitation vehicle
Travelled with preset vehicle speed, conversely, being then failure to actuate.
The above embodiments merely illustrate the technical concept and features of the present invention, and the purpose is to allow be familiar with the skill of the technical field
Art personnel can understand present disclosure and implement according to this, can not be limited the scope of the invention with this.All bases
Equivalent changes or modifications made by spirit of the invention, it should all be included within the scope of the present invention.
