The present invention is higher for existing expressway traffic accident incidence, so that because personnel caused by expressway traffic accident hurt It dies and phenomenon that property loss is countless, proposes a kind of safe-guard system and operation method for highway speed-raising, It can not only guarantee that driver standardizes driving on a highway, while early warning can be carried out to accident according to environment, keep away Exempt from the generation of highway chain of rings accident or the generation of severe and great casualty, to ensure driving safety on a highway；More Very, the above accident prevention and driving safety security problem are solved, highway Maximum speed limit can be promoted to 140 even more by 120 It is high.

In various high speed accidents, as speed it is excessively high caused by accident, the death rate is up to 74%, is more than in speed The death rate is more up to 95% in the accident of 140Km, substantially close to 100% in the accident for being more than 160KM；Therefore public generally to recognize It is high once the life security of driver and passenger can be seriously threatened by accident occur for speed, so generally believing even if setting If speed is down to safe speed as far as possible and encounters burst hereinafter, can increase by the limitation of 120Km/h do not worry thing In reaction time when event, also can reduce kinetic energy caused by high speed can not quickly absorb in a short time, make to vehicle frame itself At harm, in turn result in the harm to driving staff；However as the development of science and technology, the stability of vehicle and vehicle structure Safety is greatly improved, but due to highway layout factor, Driver's Factors, vehicle factor, environmental factor common cause So that the max. speed of vehicle is limited to 120Km/h, but also invisible obstruction is brought to highway speed-raising, so that people It will not keep in mind and how to improve the speed upper limit again.

It is in recent years even more to increase in addition, limiting overspeed of vehicle in such a way that various speed limits are taken pictures on highway The mode that section is tested the speed avoids the vehicle from slowing down taking pictures, and the phenomenon that other sections are driven over the speed limit, remain single External environment how vehicle is monitored, but these monitoring modes also limit vehicle merely by external information processing Speed, and then come the safety that guarantees vehicle, do not consider contacting between driver, vehicle and freeway facility, It embodies in the prior art, is the investment increased to the monitoring mode on highway nothing but, for example add publicity comment more, to warn Cautious driver, more setting monitoring are taken pictures, and to frighten driver, or in Expressway Service placement accident vehicle, are come live Show, etc., but it is one-sided limitation of the highway internal network to vehicle driver, i.e., has in highway discovery After car accident, subsequent vehicle can not be also notified in a short time, causes a large amount of a chain of collision phenomenons, and basic reason is Information not intercommunication between vehicle and vehicle, between vehicle and freeway facility, between vehicle and driver.

In addition, study highway up train it is safe when, general research direction be it is how safer, mainly use It mode or increases to the investment of highw ay m onitoring point, such as multiple speed measuring points is set, the speed measuring point of setting is taken the photograph using high definition It as head is taken pictures, and allows people oneself processing mode violating the regulations of taking pictures, increases the punishment dynamics of hypervelocity, come so that driver dare not carry out It is violating the regulations, while increasing to be laid with spacing terrestrial reference and carry out the moment on a highway and vehicle is reminded to maintain safe distance, with this come increase vehicle it Between interval, and then traffic safety is improved to remind driver to maintain safe distance with this, these modes are one-side, although It is capable of the driving habit of enforceable raising driver, but its strategy used is still multiple by being arranged on a highway The mode of monitoring point guarantees the safety of vehicle, and the multiple monitoring points used read after data, need by manually again The mode screened avoids data from the phenomenon of mistake occur, but also existing acquisition number to ensure the accuracy of data processing According to when, it is desirable to data acquisition it is more fewer better.

In addition, since the existing mode majority for ensureing safety does not consider the relationship between vehicle interior or vehicle, And information mutual communication is not implemented, it is main consideration is that vehicle brake, such as autobrake system avoids knocking into the back with this； Setting vehicle puts offset track system, to avoid absent-minded caused running out the way；Or setting ESP, air bag of multiple protective etc. Mode guarantees the safety of vehicle, safety accident occurs with this vehicle is reduced or avoided, risk is reduced to minimum；However nothing By the security system of the monitoring system or vehicle itself that are highway itself setting, but all have ignored a crucial core Heart problem, that is, driver information or experience are influenced caused by driving safety, will if be monitored to driver After the speed upper limit improves, driver's is a bit slack, is likely to cause serious traffic accident, however to the letter of driver It is big that breath acquisition necessarily will cause data collection capacity, and data analysis is more, in face of the data of magnanimity, certainly will be difficult to form accurately speed limit Range is to lose reference significance, but also masses are difficult to the reason of trusting such system, and the present invention has broken existing skill Habitual thinking in art is acquired analysis to driver information or experience, and is rapidly completed after getting on the bus, and calculates in advance The speed limit range of driver, then detects vehicle itself, while dynamically to driver, surrounding ring during traveling Border etc. carries out data and is acquired, and passes through the efficient operation of itself, dynamically limits speed, and feed data back to Traffic control department, well by driver, vehicle together with other Vehicle Fusions, and emphasis carries out vehicle itself and driver Dynamic monitoring, so that satisfactory vehicle and driver can improve speed to 140Km/h, and provides more for it For the guarantee of safety.

In addition, the present invention enables to vehicle when driving into highway by the way of automatically switching, system can be certainly Dynamic to switch to highway operation module, driver identity identification module identifies driver identity information, and system is combined to save Current vehicle performance parameter information provide this safe speed range travelled on a highway.

In addition, the identity information includes driver year by fingerprint, identity card or recognition of face driver identity information Age, driving age, driving license type, record case, dangerous driving record case information violating the regulations, pass through remote wireless communication module and traffic Division data platform is connected, and can obtain driver identity information in time.In addition to this, which, which itself stores, works as front truck Itself performance parameter, including dynamic property, braking, control stability, ride performance, by combining driver information most The travel speed range that regulation driver allows eventually.

In addition, there are two types of the schemes of restricted speed, in order to more accurate setting optimized range of speeds, due to being When system is just put into, there is no big datas to be counted, therefore to calculate initial velocity range at this time, firstly, in off-line mode It is lower to be divided respectively according to different age group, different driving age sections, driving license type, number violating the regulations and deduction of points situation, dangerous driving score Suitable traveling velocity interval, then according under different condition velocity interval formulate allow travel speed range table, finally As driver in use, system can match most suitable travel speed range according to driver information and combine automobile self performance Parameter completes the final regulation for allowing speed, and simultaneity factor records the driver and travels record and be uploaded to traffic department data library In.When access times are continuously increased, system can be adaptively adjusted it according to the running history of driver record and be suitble to drive Velocity interval；However after long-term use, it needs to upgrade the functions of modules, change system provides most suitable speed Mode, it is huger due to travelling record data at this time, in combination with big data and artificial intelligence technology to driver's highway Permissible velocity is judged.Firstly, obtaining driver's age, driving age, driving license type, record case violating the regulations, danger from traffic department Dangerous driving record situation makes data set according to the travel speed range under different condition, then constructs deep learning model pair The data set is trained study, and new driver information finally inputs trained model you can get it optimal traveling is fast Spend range.

In addition, can judge the driver respectively when system obtains driver information and automobile self performance parameter and be somebody's turn to do Whether vehicle meets highway driving requirement, if not meeting, the driver or the vehicle do not allow to drive into highway； Work as vehicle simultaneously during highway driving, passes through driving behavior detection module, travel condition of vehicle detection module, row Vehicle context detection module allows to pacify according in three kinds of driver, automobile, environment factor adjustment vehicle traveling processes in real time Full travel speed；Realize that dynamic adjusts.

In addition, travel condition of vehicle detection module can utilize various sensors to vehicle drive system, driving system, turn It is acquired to data such as system, braking systems and is transmitted to message processing module, while automobilism is calculated according to every terms of information The coefficient of stability, can be by visualization display automobile self-operating status information in human-computer interaction module；Firstly, environment detects mould Agllutination closes the weather data that remote wireless communication module receives the publication of current weather department；It is transmitted secondly, receiving traffic department Road congestion information and the section road type；Finally calculated according to weather conditions, wind speed, road type, road surface slippery situation degree It drives a vehicle out environment coefficient, in addition, when detecting in a certain range of front there are when interim haze, for temporarily rolling into a ball the production of mist CCD industry camera, humidity sensor and the temperature that raw when and where can not all be predicted in advance, therefore be installed by itself Sensor is spent, haze is detected as by the detection of visibility, humidity and temperature automatically；After being confirmed as haze, mention in time The driver that wakes up reduces travel speed, while the haze position, concentration information are sent to other vehicles and friendship in communication range Logical department；In addition, when a fault occurs, collision warning module incudes impact severity, it will in conjunction with the information of GPS-BDS locating module Accident information is sent to traffic department and records this place where the accident occurred point.

In addition, present invention is mainly used in how in highway speed-raising, however due to can be realized vehicle and traffic department Interconnection, when urban road when driving, then can be divided into two parts as urban road wisdom driving mode, A part is mainly responsible for whether safe driving detects to driver, such as fatigue driving, driving making and receiving calls behavior carry out Supervision then stores processing module record behavior information by information and is uploaded to if driver has the above dangerous driving behavior Corresponding dangerous driving point is deducted to the behavior by traffic department by relevant traffic department, which will be in starting highway mould It is used, highway can not be driven into if score is too low or can only be gone on a highway when formula with lower velocity interval It sails；Second part major function is road congestion information, Weather information, the geography that current city is pushed for driver's real-time intelligent Information on services such as position etc..

The coefficient of stability be divided into it is low be 0.3, in be 0.7 and a height of 1,

It is sunny, cloudy, cloudy for height, be that heavy rain, heavy rain, torrential rain, hail, snowfall are low within moderate rain；

Belong to height below moderate breeze, during moderate breeze to strong breeze is, six grades the above are low；

Highway, municipal highway, provincial highway, national highway belong to height, during country highway or rural highway belong to, sky way, dirt road Belong to low；

Visibility is height in 4Km or more, is between 0.6-4Km, and in 0.6Km, the following are low；

When calculating the coefficient of stability, multiple parameters are all satisfied Shi Caineng and take high stable coefficient, take most as long as having one to be unsatisfactory for The low coefficient of stability.

In coefficient of stability highest, then speed is limited to 140KM, the then section max. speed thus when non-high-speed；

When to be middle, be then limited to 0.7*140=98KM per hour, be then when to be low 0.3*140=42 kilometer per hour；

Coefficient calculating then is carried out according to Maximum speed limit when if it is non-high-speed section；

Fig. 7 is the method for real-time adjustment flow chart of safe speed range in S2, and its step are as follows:

Step B: after the big face of system is come into operation, by acquiring the driving historical record in each vehicle system, according to collected Speed corresponding to danger coefficient and the coefficient of stability makes data set, and in calculated result speed minimum lower than high speed, refusal is driven The person of sailing drives to drive into highway；

Expressway safety safeguards system in the present invention can be limited according to driver's self-information and vehicle self information Its speed driving range on a highway is made, while being exercised supervision to driver's driving procedure, driver is avoided to drive in violation of rules and regulations Sailing causes the accident, while the present invention can be according to automobile in the process of moving according to driver status, automobilism situation And environment variation adjusts the permitted best safety drive speed of the vehicle in real time, can also make phase when a fault occurs Measure should be alarmed to avoid heavy casualties caused by a chain of car accident, reduce injures and deaths and loss to greatest extent.Realize height Fast highway efficient operation.On the other hand highway can be promoted to be promoted to 140 kilometers per hour from current 120 kilometers of speed limit often Hour is even higher, and this system structure is simple, and cost is relatively low, easily uses and popularizes on real vehicle.With the liter of highway The promotion of grade transformation and Maximum speed limit, the system preferably can play a role and provide service, and long-range objectives are to break through high speed Highway maximum speed limitation, to reach the personalization of bicycle, differentiated traveling.

The above is a preferred embodiment of the present invention, it is noted that for those skilled in the art For, without departing from the principles of the present invention, it can also make several improvements and retouch, these improvements and modifications It should be regarded as protection scope of the present invention.
