Brief description of the drawings
Fig. 1 is a kind of global unobstructed degree voice announcer structure chart of circuit proposed by the present invention.
Embodiment
Reference picture 1, the global unobstructed degree voice announcer of a kind of circuit proposed by the present invention, including：Bicycle statistical module, list
Car weighting block, collect statistics module, voice broadcast module and subsections mergence module.
Bicycle statistical module, is connected with vehicle mounted multimedia communication module, for obtaining each vehicle traveling shape in target road section
State data, vehicle running state data include speed average and subjective assessment value.
In present embodiment, speed average value is gathered by vehicle speed sensor.Or, it is preset with and adopts in bicycle statistical module
Collect periodic quantity, it is used to periodically gather the distance that each vehicle is travelled in target road section according to collection period value, and for root
Speed average value is calculated according to operating range and running time.Specifically, bicycle statistical module is according to GPS location periodicity collecting vehicle
Current location, then obtains vehicle by the way that current location to be subtracted to the vehicle location collected for the first time in target road section and exists
Operating range in target road section, then collects the vehicle in target road section for the first time by the way that current acquisition time is subtracted
When time obtain vehicle running time in target road section, it is equal then to obtain speed by operating range divided by running time
Value.
In present embodiment, target road section is the section between two neighboring crossing on same route.
For example, existing road A before and after intersect with road B and road C, by road A positioned at AB with one voice with AC with one voice between
Section A0 be used as target road section.Vehicle Q is 8：58 enter section A0, and bicycle statistical module was gathered on the A0 of section per N minutes
Once on the section each vehicle position, it is specific it is assumed that bicycle statistical module collects vehicle Q's on the A0 of section for the first time
Time is 9：00, then, the time that second and third time of bicycle statistical module collects vehicle Q on the A0 of section is respectively 9：00+
N、9：00+2N, the position of second collection and the distance between position of collection for the first time are S1, the position of third time collection with
The distance between position of collection is S2 for the first time.In this way, 9：This time point of 00+N, speeds of the vehicle Q on the A0 of section
Average is S1/N；9：This time point of 00+2N, speed averages of the vehicle Q on the A0 of section is S2/2N.In the present embodiment, it is
Collection period value N, can be set to 1-3 minutes by guarantee speed mean value computation precision.
All it is the vehicle calculated traveling total in target road section when calculating speed average each time in present embodiment
Average in time, rather than the average between acquisition time twice.In this way, being conducive to by speed average to the unobstructed degree in section
Overall presentation.
In present embodiment, subjective assessment value is the subjective conjecture of the unobstructed degree in section that driver is uploaded by vehicle mounted multimedia
Numerical value.The setting of subjective assessment value, can avoid making because part driver likes going slowly on some actual very unobstructed sections
Into speed average it is unobstructed to section degree assess adverse effect.
Bicycle weighting block, is connected with bicycle statistical module, for assigning one, vehicle according to vehicle running state data
The unobstructed degree of solo running.In present embodiment, weighted calculation model is preset with bicycle weighting block：
The unobstructed degree of solo running=speed average value/current road segment speed limit+subjective assessment value.
In present embodiment, it is contemplated that speed average value is up to equal to current road segment speed limit, speed average value/current road
The maximum of section speed limit is 1, so, it is subjective in order to balance effect of the subjective assessment value when calculating that solo running is unobstructed to spend
Evaluation of estimate value between 0 to 0.5.
Collect statistics module, is connected with bicycle weighting block, unobstructed for calculating each solo running on current goal section
Degree average value is used as the unobstructed degree of sections of road.For example, traveling has 10 cars on current goal section, then the section current driving is led to
Smooth degree travels the average value of unobstructed degree for this 10 cars.
Voice broadcast module, is connected with collect statistics module, for obtaining the unobstructed degree of traveling in each target road section and making
It is made voice document.Voice broadcast module is also connected with vehicle mounted multimedia, is entered for voice document to be sent into vehicle mounted multimedia
Row is reported.
Subsections mergence module, it is used to close unobstructed two target road sections of degree identical of adjacent on same route and traveling
And into a new target road section, reported after new target road section association then is travelled into unobstructed degree by voice broadcast module.
Specifically, such as road A before and after intersects with road B and road C after again intersect with road D, road A positioned at AB with one voice with AC with one voice
Between section A0 as a target road section, road A be located at AC with one voice with AD with one voice between section A1 be used as one
Target road section.If A0 current drivings unobstructed degree in section is different from the unobstructed degree of section A1 current driving, by section A0 and its
The unobstructed degree association of current driving is reported by voice broadcast module, and section A1 is associated by voice with the unobstructed degree of its current driving
Broadcasting module is reported.If, can be by if A0 current drivings unobstructed degree in section is identical with the unobstructed degree of section A1 current driving
Section A0 and section A1 are incorporated as a target road section, and by the target road section after merging associate current driving it is unobstructed spend into
Row is reported.So so that voice broadcast is more succinct so that current road conditions report de-redundant and deposit essence, advantageously ensure that driver couple
The understanding of current road conditions.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
