Description
Technical field
The present invention relates to computer software fields, and in particular to a kind of vehicle that promoted passes through traffic intersection anticipation accuracy
Method and device.
Background technique
With the rapid development of science and technology, the passing control system of current existing traffic light intersection automatic driving vehicle is
Realize the method that intelligence anticipation passes through traffic light intersection.The principle of this method is know will be by the position of crossing vehicle
It sets, under the premise of the information such as the timing of speed and traffic lights, can accurate judgement vehicle pass through the red green of front
Vehicle driver simultaneously is informed in such a way that voice and image warn simultaneously in lamp intersection.
The passing control system of traditional traffic light intersection automatic driving vehicle depends on the current vehicle speed of vehicle, row mostly
It sails distance and vehicle receives the bright sequence information of signal lamp, judge that vehicle vehicle under current vehicle speed is by these parameters with this
It is no can by front will by crossing.
However, the assessment parameter of this mode is fixed, and do not consider such as itself speciality of festivals or holidays, weather and driver
The influence of the external factors to judging result such as otherness, lack the side for realizing that personalized customization anticipation passes through traffic light intersection
Case, memory and the specific functions such as shared.
In addition, traditional pre-judging method can not yet fill for special driving population (for example, new hand or female driver)
Divide the real time data using city traffic light system, anticipation is caused to become more by the not high problem of the accuracy of traffic light intersection
For protrusion.

It includes: morning peak, evening peak, overtime section, common etc.；It may include: sleet for Weather information, be exposed to the sun, be extremely cold, common
Deng.
Secondly, generating the attribute of the KEY-VALUE memory module of NoSQL database according to the union of each parameter above
KEY, VALUE indicate the error time by crossing.The database is as shown in table 1:
Table 1
If the anticipation time pushed there is no the history error information that the user passes through the crossing in the database
Then the user is recorded by the real time at the crossing and calculates actual error data to the user；Finally, utilizing the reality
Border error information updates the history error information of the user in the database.
If looked into there are the history error information that the user passes through the crossing according to the information of the user in the database
Ask the historical data that the user passes through the crossing；
When the anticipation time and the historical data being compensated, the compensation anticipation time are calculated, and the compensation being prejudged
Between push to the user.
It in one embodiment of this invention, is that the anticipation time is carried out vector sum operation with the history error information to obtain
The compensation prejudges the time.
Then, the user is recorded by the real time at the crossing and calculates actual error data；
Finally, updating the history error information of the user in the database using the actual error data.
Citing:
The personal information of driver are as follows: in the 28 years old women in Pekinese, i.e., be 11 street traffic lights of Kechuang by the crossing passed through
1；External factor are as follows: common morning peak is comfortable.
By the table it is found that corresponding in the database is Article 2 match information, pass through the history margin of error at the crossing
According to being 1000ms, and the driver this by the actual error at the crossing be 800ms, therefore the driver is passed through into the crossing
History error added up and averaged, i.e., original 1000ms is changed to 900ms.The updated database such as table 2
It is shown,
Table 2
Fig. 2 is the schematic diagram for promoting vehicle and prejudging the device of accuracy by traffic intersection of embodiment of the present invention, should

History error information；
If the anticipation time pushed there is no the history error information that the user passes through the crossing in the database
To the user；After the user is by the crossing, the user is recorded by the real time at the crossing and calculates actual error
Data；The actual error data are stored in the database, pass through the history error information at the crossing as the user；
If gone through to the anticipation time with this in the database there are the history error information that the user passes through the crossing
History error information compensates calculating, with the anticipation time compensated, and the anticipation time of the compensation is pushed to the user；
After the user is by the crossing, the user is recorded by the real time at the crossing and calculates actual error data；It should
Actual error data and the history error information are added up and are averaged, and update the user in the database with the mean value
History error information.
Optionally, the driving information of the vehicle includes the distance of the travel speed of vehicle, vehicle away from stop line, traffic letter
Signal lamp information includes the traffic lights timing information at the crossing.
Optionally, which uses the data pattern of KEY-VALUE type, and is stored in NoSQL database
In.
Optionally, which includes: compensation calculation module 23, wherein the compensation calculation module for pair
The anticipation time and the history error information carry out vector sum operation and obtain the anticipation time of the compensation.
Since promotion vehicle provided in this embodiment is above-mentioned promotion vehicle by the device that traffic intersection prejudges accuracy
The corresponding device of the method for accuracy is prejudged by traffic intersection, therefore this will not be repeated here.
The method and device for promoting vehicle and prejudging accuracy by traffic intersection provided through the invention, can be according to reality
When the driving information and traffic lights information of the vehicle that acquire, using the storage characteristics of NoSQL database, in conjunction with driving vehicle
When weather and the factors such as time and the attributive character of different drivers, the history mistake that inquiry driver passes through same crossing
Difference data, the anticipation time at crossing will be passed through by calculating vehicle.In addition, according to vehicle by the real data of traffic intersection, it is real
When more new database in history error information, effectively increase vehicle pass through traffic intersection prejudge the time accuracy, guarantee
