Compared with prior art, the present invention has the following advantages:
In the Dangerous Area analytical approach of the embodiment of the present invention and device, the driving data that vehicle is uploaded is analyzed, if the vehicle fleet size that burst driving condition occurs in certain section exceedes predetermined threshold value, just Dangerous Area is confirmed as in this section, and information is sent to the vehicle entering or drive towards this Dangerous Area, with call user's attention, make user can evade in time or take other measures.
Embodiment
Below in conjunction with specific embodiments and the drawings, the invention will be further described, but should not limit the scope of the invention with this.
With reference to figure 1, the Dangerous Area analytical approach of the present embodiment comprises the steps:
Step S11, receives the driving data that multiple vehicle is uploaded;
Step S12, analyzes described driving data, if the vehicle fleet size that burst driving condition occurs in a section exceedes predetermined threshold value, then Dangerous Area is confirmed as in this section;
Step S13, sends information to the vehicle entering or drive towards this Dangerous Area.
In step S11, driving data can be uploaded by the car machine be arranged on vehicle, such as in vehicle travel process, car machine can obtain the driving data of vehicle by sensor and/or wagon control bus (such as CAN), then uploaded by communications such as 3G network, 4G networks, such as, can be uploaded to cloud server analysis.Whether this driving data includes but not limited to the speed of a motor vehicle, acceleration, whether lane change, takes a sudden turn, or wherein multiple combination in any of braking in data.
Uploading of driving data can be carried out in real time, or also can carry out by interval Preset Time.Such as, car machine can by driving data buffer memory in memory, and each Preset Time is by the data upload of buffer memory.
In step S12, the driving data uploaded is analyzed, judge whether whether to have in the driving data of a large amount of vehicle in a certain section and all there is burst driving condition, whether such as a certain section has interim, burst, a large amount of vehicle brake data upload, if there is this situation, so Dangerous Area can be confirmed as in this section.
Furthermore, can judge whether the vehicle fleet size that burst driving condition occurs exceedes predetermined threshold value, such as can the driving data uploaded be analyzed, judge whether the quantity of the vehicle braked in a certain section exceedes default first threshold, namely judged whether that a large amount of vehicle all brakes in this section; Judge whether the quantity exceeding the vehicle of Second Threshold at a certain section acceleration exceedes the 3rd default threshold value, has namely judged whether a large amount of vehicle all at the unexpected acceleration or deceleration in this section; Judge whether exceed the 4th default threshold value in the quantity of the vehicle of a certain section lane change, namely judged whether a large amount of vehicle all in this section lane change; Judge that whether the quantity of the vehicle taken a sudden turn in a certain section is more than the 5th threshold value, namely judged whether that a large amount of vehicle all takes a sudden turn in this section.If one or more in above-mentioned condition is met, so just can judge that this section belongs to Dangerous Area, such as hot work in progress, have falling rocks, have and subside.
Such as, in the routine craspedodrome section at a non-crossing, if the driving data uploaded shows that the operation of brake, lane change all taked by vehicular traffic in this section, so often show this section possibility hot work in progress, or there is burst collapsed condition on road surface, Dangerous Area can be regarded as.
As a preferred embodiment, when judging Dangerous Area to driving data analysis, the driving data that vehicle is uploaded at crossing place can be shielded in advance.Owing to often needing to do the operations such as lane change, brake, turning at crossing place, therefore this part data mask to be fallen, to avoid crossing erroneous judgement to be decided to be Dangerous Area.
After confirmation Dangerous Area, information can be sent to the vehicle entering or drive towards this Dangerous Area.Such as, can search for the regional extent of the pre-set radius of Dangerous Area, find and enter or close to the vehicle of this Dangerous Area, after finding, send information to these vehicles.
The content of information can comprise Dangerous Area position, apart from this Dangerous Area distance value, arrive time one of them or the combination in any of this Dangerous Area, but be not limited to this.
Such as, if the vehicle receiver in travelling is to this information, showing section, front is Dangerous Area, possible hot work in progress, and so user just can Reroute in time, to avoid blocking up or the generation of unsafe condition.
As above, adopt the Dangerous Area analytical approach of above-described embodiment, can, when without the need to detecting by camera, manually not reporting, according to driving data automatic analysis determination Dangerous Area, and remind vehicular traffic to note in time.
With reference to figure 2, the Dangerous Area analytical equipment 20 of the present embodiment comprises data reception module 201, data analysis module 202 and reminding module 203.
Wherein, data reception module 201 can receive the driving data that multiple vehicle is uploaded; Data analysis module 202 can be analyzed the driving data uploaded, if the vehicle fleet size that burst driving condition occurs in a section exceedes predetermined threshold value, then Dangerous Area is confirmed as in this section; Reminding module 203 can send information to the vehicle entering or drive towards this Dangerous Area.
About the more information of this Dangerous Area analytical equipment 20, refer to the associated description about Dangerous Area analytical approach in previous embodiment, repeat no more here.
This Dangerous Area analytical equipment 20 such as can be integrated in cloud server inside, can should be coupled with cloud server by communications such as 3G network, 4G networks with the car machine be arranged in vehicle.
The modules of this Dangerous Area analytical equipment 20 and inside thereof can adopt the mode of software program to realize; Also special or common hardware can be adopted to realize, such as, adopt special IC (ASIC) or field programmable gate array (FPGA) to realize; Or, also can adopt the mode of software and hardware combining to realize, such as, adopt processor to realize in conjunction with the embedded system of peripheral circuit and embedded program.
Although the present invention with preferred embodiment openly as above; but it is not for limiting the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible variation and amendment, the scope that therefore protection scope of the present invention should define with the claims in the present invention is as the criterion.
