Description
Technical field
The present invention relates to vehicle braked effect in the traffic safety field, the very first time of the vehicle that especially can make travels down when being in an emergency braking realize follow-up vehicle in braking, reach the purpose that prevents vehicle rear-end collision.
Background technology
At present; Known car brakeing process be by human pilot find that the stop, tail and number plate light of the front truck tailstock is bright, find roadblock (causing) to occur on the place ahead fault car (causing) warning mark or the road by disaster by vehicle itself thus take the car brakeing measure, reach and prevent the purpose that knocks into the back or collide.And more situation is that human pilot must rely on bright the taking of stop, tail and number plate light of the adjacent vehicle in front to brake; And the deadly defect of this mode of braking is; Thereby each follow-up vehicle must be found the bright braking of the stop, tail and number plate light of the adjacent vehicle in front; This passive mode of braking of transmitting brake signal successively makes and knocks into the back unavoidably.
Summary of the invention
Be convenient narration, the road of indication of the present invention saidly only is example with highway (but be not limited to highway, promptly also comprise one-level, secondary, three grades, Class IV highway and racing track etc.) following; The signal of indication of the present invention only is example with wigwag (but be not limited to wigwag, promptly also comprise alarm etc.); The automatic control of indication of the present invention is that the automated wireless telechiric device (contacts with vehicle brake pedal, when vehicle meets or exceeds the speed of a motor vehicle of regulation, is activated.When vehicle is in case of emergency braked; Because point apparatus and a last point apparatus at the beginning of detent has one; Detent leaves just point apparatus and a mistiming is arranged when touching last point apparatus; When this mistiming was lower than the normal brake application required time, wireless teleautomatics had sent wireless signal, and this signal is launched through the port that is located at roof; Receive and opened wigwag thereby be installed in radio receiver on the pedestal on highway limit, reach the purpose of the follow-up vehicle of reporting to the police.Port and highway xsect clock direction on one point become 45 ° of angles; The manual control of indication is the hand-hold wireless telepilot.
In order to prevent and reduce the generation of the frequent rear-end collision of existing vehicle; The invention provides a kind of vehicle rear-end collision signal alarm (the manual manually-operated of automatic control) extension amplification system that prevents; Can be this information of vehicle (roadblock car) that on highway, is in an emergency braking to stop through system of the present invention; Utilize the every wigwag screen on the pedestal of 25 meter amperes dress in highway limit to send wigwag (amplification) to follow-up (extension) vehicle; Also can alarm device be installed simultaneously on pedestal, reach purpose at very first time retarding braking to strengthen the warning effect.
The technical solution adopted for the present invention to solve the technical problems is: (direction to the car with go car direction) whenever buried pedestal underground at a distance from 25 meters distances on the highway both sides; Pedestal is high 5 meters; On pedestal, be provided with high 1.2 meters from 3.8 meters of express highway pavement; Wide 0.3 meter wigwag screen; Wigwag screen and highway xsect ten o'clock direction become 45 ° of angles, on pedestal from 3 meters to 3.8 meters of express highway pavement and highway xsect on one point the clock direction become 45 ° of angles that radio receiver is set, the turn on lights light signal shields switch when radio receiver receives wireless signal; Overhead 1 meter is provided with round-the-clock manual manual operation switch (also can distinguish night) in the pedestal bottom, wireless receiving switch and the parallel connection of manual manual operation switch's circuit, and the wigwag screen between each pedestal is by wire coupling.When launching wireless signal by automated wireless telechiric device on the roadblock vehicle or hand-hold wireless telepilot; Radio receiver on the pedestal receives wireless signal and turn on lights light signal screen; Wigwag screen energising on this pedestal is also lighted; Behind this pedestal (roadblock car rear) one group (80 is one group; Each 25 meters at interval) wigwag screen moment lighted simultaneously, and the driver on all vehicles at roadblock car rear at very first time braking deceleration simultaneously, prevents the purpose that knocks into the back thereby reach when seeing the wigwag screen of lighting.And the place ahead of roadblock car does not have bright wigwag screen, so can continue the speed that keeps highway to set.When the roadblock car did not have automated wireless telechiric device or hand-hold wireless telepilot, the human pilot roadblock car that can speed away was run to the highway limit from own nearest pedestal, presses the manual manual operation switch, prevented the purpose that knocks into the back thereby reach.The principles of science that can realize this purpose is: we are set with 100 meters of six equispaceds between each car of car and with 120 kms/hour at the uniform velocity go; At the beginning of first car was since 1 second, brake when the end braking stopped in 3.5 seconds; We suppose that first car lags behind 50 meters in the process of braking; And second car, the 3rd car, the 4th car and the 5th car all knock into the back in first car braking procedure; Braking distance is-12 meters of 500 meters (six headstock spacing distances of first tailstock to the)-50 meters (delay distances of first car) (length of middle four cars)=438 meters concerning the 6th car like this; And first car stops from beginning braking; With the time of the 6th car be shared, will go 3.5 seconds * 33 meter per second=115.5 meter of the 6th car in 3.5 seconds just, last the 6th car possibly knock into the back and the actual range that goes that do not knock into the back is a 438-115.5=322.5 rice; This distance is (first car become the roadblock car) of fixing; And at this moment the 6th car is not know that first car stopped, that is to say after nearly 10 seconds the 6th car will catch up with the 5th the car tailstock, and these 10 seconds just the human pilot of first car get off in the car switching time under the pedestal of running to the highway limit; Be less than the 6th car because when avoiding knocking into the back required time when this time with the 5th; To knock into the back with the 5th car, when in this time because wigwag screen is lighted more than the 6th car because when avoiding knocking into the back required time with the 5th, the 6th car is safe.
We know that the mode that traditional preventing knocked into the back is that when vehicle became the roadblock car, human pilot should be placed the caution road sign in 200 meters behind car, to warn follow-up vehicle.This mode one is dangerous concerning human pilot, particularly under the situation of low visibility.The 2nd, consuming time; According to the teenager of national regulation in 1981 standard of reaching the national standard for physical training, 100 meters of track and fields be 12 seconds up to standard, that is to say that placing warning sign must run 200 meters behind car; Need 24 second time, and this distance of 200 meters is with per hour the vehicle ' of 120 kms only need 6 seconds.Vehicle on highway from now on is more and more intensive, and under the situation that the speed of a motor vehicle of permission improves constantly, braking time is calculated with millisecond, this method is very backward.
" traffic accidents characteristic case study " in 2009 the 35th volumes of certificate the 10th phase " industrial safety and environmental protection " (by work 2009-03-30 such as Peng Meng, Wang Xinquan) demonstration; Highway knocks into the back and accounts for 45% of total accident; Cause death, injured 70% and 74% of total death, the number of injured people that account for respectively, the economic loss that causes accounts for 55%.
According to Chengdu Business, in 28 mornings of May in 2012, a mist appears suddenly in Jingzhu express way Xinyang section, causes 13 traffic accidents, dead 8 people, and 13 people are injured; Peaceful high speed Mengcheng, Lip river 19 cars of section joined ring and knocked into the back at about 9 pm on June 9th, 2012, and accident causes 11 dead 59 to hinder.Report according to the wide news in centre, 20 car chains of rings take place and knock into the back in the highway in U.S. Urban Old Kingsoft on June 27th, 2012, and the casualties is not quite clear.These all be this year five, the June occurrence, explain that no matter this situation is that domestic or external every day is also in continuous generation, so the injures and deaths that cut down traffic accidents are very urgent long-term tasks of highway at present and in the future
Report according to the wide news in centre again, last year, China was because the death toll that traffic accident causes surpassed 60,000 people (2011).If through enforcement of the present invention, can reduce by 15% mortality ratio, just saved 60000 * 70% * 15%=6300 people's life.Compensate 300,000 in every the dead by insurance company; 6300 * 300000=18.9 hundred million reduce the loss every year (just in the China's Mainland; Do not calculate other country beyond the China's Mainland); If therefore increase by 5% automobile consumption amount (owning amount of the present automobile of China is 7,500 ten thousand), then can spur the domestic automobile consumption of 3,000 hundred million (with average 80,000 yuans of calculations of each car).If we constantly reduce the dead injury rate of highway, this spurs domestic demand to China, drives the tertiary industry thereby increase consumption, creates more jobs, with producing huge economic benefit and social benefit.Because in that people-oriented, advocate the present society of private space, automobile is the still embodiment of individual's identity status not, still has the symbol of individual wealth.But a lot of citizens that have the ability consumption or do not consume car as first-selection fear automobile consumption because of fearing highway " killer ".
Suggestion is when the speed of vehicle during for 80 kms per hour to 100 kms per hour, and wigwag screen pedestal is suitable for being placed in the highway both sides, is convenient to the hand-hold wireless telepilot like this and starts that wigwag shields switch and the manually-operated wigwag shields switch.Also can avoid vehicle to sweep away roadbed and play obstruction effect (this set mode is specially adapted to hills and mountainous region such as Jassy's highway).When the speed of vehicle for 120 kms per hour when per hour 150 kms are above; Pedestal is suitable for being placed on the highway central partition, on the highway fast, is more suitable for the automated wireless telechiric device like this and starts wireless receiving switch (this set mode is specially adapted to Plain and big area such as the Jingzhu express way highway of vehicle flowrate).
Why pedestal is spaced apart 25 meters, and this is for reduce manual manual operation switch's time as far as possible.Also be that wireless signal for the automated wireless telechiric device on vehicle emission is received by the other wireless receiving switch of highway in the car brakeing process as much as possible.
China's highway total kilometrage has reached 8.4 ten thousand kms at present; If (on same pedestal, be provided with tow sides wigwag screen, the direction that vehicle comes is spread its tail with the wireless receiving switch interval of the direction of going and is closed, and reaches the effect of mutually noninterfere) on the highway central partition with every at a distance from 25 meters pedestals; Need 3,360,000 pedestals altogether; With 5000 yuans of calculations of each pedestal cost, total cost is 16,800,000,000 yuans, and (if only be provided with on the highway both sides, then each must 1,680,000 pedestals with going the car direction for direction to the car; 2500 yuans of each costs are so total cost is constant).If it is 3000 yuans that each car is installed the automated wireless telechiric device, with 7,500 ten thousand automobiles that China has at present, total cost is 2,250 hundred million yuans (also the automated wireless telechiric device can be installed, only with hand-hold wireless telepilot and manually-operated).
