The graphic element data stored in memory builds the virtual scene of the corresponding driving adaptability ability item.
Step 3：Processor receives the feedback command for the corresponding driving adaptability ability item detection that handle is sent；
The virtual field that processor detects according to the examination criteria of each driving behavior monitor ability item to driving adaptability ability item
For object logical model in scape according to being controlled, the object logical model includes controlled auto model, controlled label
Model and running section environmental model etc.；The fortune of each object logical model in different driving behavior monitor ability item detection process
The differences such as dynamic rail mark, the direction of motion, movement velocity, user correspond to driving adaptability ability item by the button in operation handle and examined
Fractional object logical model in the virtual scene of survey, to realize the detection of driving adaptability ability item；Processor is anti-to producing
The time presented the correctness of instruction and/or produced needed for feedback command is recorded；
In addition, also the ambient brightness of each scene is adjusted for processor, according to the inspection of different driving behavior monitor ability items
Survey demand, selection are adjusted to different ambient brightness；
After the driving adaptability ability item of selected detection, detection start before in being fitted on display unit to the selected driving
Answer operating instruction corresponding to sexuality item to be shown, inform how user carries out detection operation；
After processor control object logical model starts action, start recording produces the time point of feedback command every time, meter
Calculate the time every time needed for generation feedback command；The above-mentioned time is just effective only when caused feedback command is correct, if production
Then the corresponding required time is invalid for raw feedback command mistake, repeat step 3；Above-mentioned caused feedback command is correctly specific
Whether corresponding with the object logical model in corresponding virtual scene at that time refer to sometime feedback command caused by point；
In detection process, user is sent at some or several time points according to the real-time scene shown on display unit
Feedback command.
Step 4：Processor judges the testing result of driving adaptability ability item detection；Head-mounted display apparatus passes through language
The mode of sound, word or picture informs whether user passes through detection；
The correctness of the generation feedback command recorded in step 3 and required time and the difference of memory memory storage are driven
The examination rating fraction table of comparisons for sailing suitable sexuality item is compared, and obtains the ranking score of the driving behavior monitor ability of user
Number；Communication component will detect the examination fraction of obtained different driving behavior monitor ability items using wired or wireless communication mode
Data (including individual event rating fraction and overall merit fraction) are transferred to supervising platform server, are easy to examine supervisor to look into
Read.In preferred embodiment, above-mentioned communication can be WIFI, bluetooth, ZigBee, UWB, Z-wave, 3G, 4G or
5G.Pass through above-mentioned technical scheme so that real without examining personnel on site to supervise when carrying out the detection of driving behavior monitor ability
Show the purpose of the supervision of Site Detection zero, greatly save examination manpower.
Sent in addition, communication component can also gather physical characteristics collecting device user biological characteristic information to supervising platform clothes
The user biological characteristic information received is compared with subscriber identity information database for business device, supervising platform server, knows
Other user identity, and the examination fraction with detecting obtained driving behavior monitor ability item is associated.Above-mentioned subscriber identity information
Database can be biological attribute data storehouse of the public security traffic relevant departments to the advance collection of driver.The utility model knows identity
Other technology is applied in the detection of driving behavior monitor ability item, can realize driving behavior monitor ability item examination fraction and user identity
The synchronous transfer of information, examination personnel can remotely complete the fraction examination to testing staff, be gone to without testing staff specified
Detection place.Whole detection process efficiently, fast, without third party's human and material resources aids in.
Although embodiment of the present utility model is described above, the utility model is not limited to above-mentioned tool
Body embodiment and application field, above-mentioned specific embodiment are only schematical, directiveness, rather than restricted
's.One of ordinary skill in the art is not departing from what the utility model claims were protected under the enlightenment of this specification
In the case of scope, the form of many kinds can also be made, these belong to the row of the utility model protection.
