Description
Technical field
The present invention relates to a kind of rear-end collision method for early warning and device thereof.
Background technology
Now, the F-Zero that express highway generally limits vehicle is 110 kilometers of compact cars, 90 kilometers of Oversize vehicles, and in fact many vehicles have all surpassed Maximum speed limit.(the statistics date: 9 to 15 July in 2003): the Oversize vehicle speed per hour surpasses has 124 more than 110 kilometers, and surpassing has 447 more than 120 kilometers according to " express highway exeed the regulation speed vehicle announce " of traffic constable army unit of Department of Public Security of Guangdong Province; The compact car speed per hour surpasses has 893 more than 130 kilometers, and surpassing has 4682 more than 140 kilometers.(network address: WWW.gdgajj.com) in the serious vehicles peccancy of Gong Buing, driving over the speed limit July above has 225 twice, and maximum one reaches 6 times in Guangdong Province Traffic Police Headquarters website.Speed per hour surpass 170 kilometers have 21.And 5, in June, have 23, maximum cars that drive over the speed limit more than 11 times reach 22 times; Speed per hour surpasses 170 kilometers having 52 (institute's train of vehicles is various places vehicles such as Guangdong, osmanthus, Hunan, Hubei Province, Jiangxi, Fujian, wash rice, Soviet Union, Anhui, Henan, Shanxi, capital, wherein contains foreign nationality's car and Hongkong and Macro's through train in a small amount.Partly report according to 2003/07/20,07/27,08/01,08/03,08/10,08/17,08/24,08/31,09/07,09/14,09/21,09/28,10/05,10/12 " Yangcheng Evening News " B2, A10 version).
According to 03/09/28 " Yangcheng Evening News " A10 version with the first especially big title of version " traffic accident average every day take by force life 270 people " (subhead: the Ministry of Public Security discloses surprising information) report Nanjing message on the same day, according to the same day " Modern Express ": the data that Traffic Administration Bureau of the Ministry of Public Security provides recently show, the 1-8 month in this year, 448535 of road traffic accidents take place in the whole nation altogether, cause 66180 people's death, have 270 people to be killed in an automobile accident average every day, and 330331 people are injured, 25.6 hundred million yuan of direct economic losses.China's automobile quantity increases day by day, and the containment road traffic accident is very urgent the sixth of the twelve Earthly Branches!
Vehicle in travelling with suitable speed has extraordinary circumstances need slow down or glancing impact when chaufeur catches sight of the place ahead, and its first reaction action is exactly to unclamp throttle at first rapidly, utilize the resistant effect of driving engine to lower the speed of a motor vehicle; Next is then takes corresponding foot brake measure.
At present, various automobiles all are by the braking indicator lamp of this tailstock portion this car control speed situation to be warned pursuit-type vehicle, but because traditional braking indicator lamp master cock such as mechanical switch, pneumatic switch, pushswitch all are arranged on the foot brake maneuvering system of vehicle, therefore, make tailstock braking indicator lamp shinny, must enter by the time and implement the foot brake operation time period.
After chaufeur depresses brake pedal, also have a car brake not have the play motion of brake action, above-mentioned three kinds of its closings of contact of braking indicator light switch will experience the play motion of this brake pedal before all unavoidablely.After play motion finished, except that mechanical switch can directly be promoted the closing of contact, pneumatic or pushswitch also will experience the closing of contact of a pressurization ability driving switch.Therefore, be arranged on the car brakeing maneuvering system, although traditional braking indicator light switch just make the braking indicator lamp shinny sluggishness the one long time that should not ignore.
It is shinny to find that from chaufeur situation begins up to the braking indicator lamp, this responsive time course that constantly must a key of experience: 1, driver reaction time (length varies with each individual, be generally 0.3-1 second); 2, decelerate to operation transfer time of implementing braking (chaufeur lifts the pin that is placed on the acceleration pedal to unclamp throttle, then pin is transferred on the brake pedal, the fastest also need several seconds zero point) from pine tar; 3, as mentioned above, cause the sluggish closing period of braking indicator light switch contact because of reasons such as brake pedal free strokes.As a result, this crucial time course by above three continuous times combination has caused the delay of car brakeing indicator lamp shinny.
Because the delay of tailstock braking indicator lamp is shinny, often make that the pursuit-type vehicle of running at high speed is correct judges that safety distance between two cars is affected even is caught unprepared.For example, the at high speed highway allows 110 kilometers calculating of speed per hour, and the distance that vehicle was passed by at 0.5 second just has 15 meters! Under unexpected situation, take place or avoid a calamitous major accident, often just be decided by that pursuit-type vehicle walks this several seconds zero points of more than ten meters or even 3 meters 0.1 second! Therefore, people sum up " rather stopped three fens, do not rob one second " this penetrating warning speech after having accumulated a large amount of lessons written in blood.
Make the car brakeing indicator lamp shinny immediately as early as possible when chaufeur is found situation, this is the potential problem of a direct relation vehicle safe driving, but because the tool of problem own is necessarily disguised, so that its importance is ignored by people always.A large amount of traffic accident cases can prove, at unexpected crucial moment, only need to have striven at emergent pre-warning time the lead at several seconds zero point, and accident can be dissolved fully or degree of damage is greatly alleviated.
In view of suitable distance and vehicle that vehicle per second under the suitable speed of a motor vehicle is walked are suddenly stopped back inertia towards preceding suitable distance (seeing attached list), therefore, at the crucial moment that the vehicle of express highway in the middle of travelling need slow down or brake, the measure of sending early warning information to pursuit-type vehicle is travelled to ensuring safety the important meaning that can not be ignored is just arranged as early as possible.Concerning the vehicle that often travels with nearly hundred kilometers speed per hours, just be enough to the huge traffic accident that causes to betide moment several seconds short zero point; Otherwise, get hold of the generation that also can avoid a disaster this several seconds short zero points fully." a chain collision " serious rear-end collision of car crash takes place on the express highway both at home and abroad frequently, and the vehicle that meets accident mostly is with not obtain safety distance ahead of time relevant.
The following table inertia that is vehicle behind distance that per second under the different speed per hours is walked and emergency braking is towards preceding stopping distance.
The inertia of vehicle vehicle behind distance that different speed of a motor vehicle per seconds are walked and emergency braking is towards preceding stopping distance (subordinate list)
In addition, vehicle ' is in bustling highway section or during the low speed highway section, and is lower just because of the speed of a motor vehicle, navigating mate is generally lost vigilance, so that its front-and-rear vehicle distance of people having a common goal's vehicle in travelling usually less than the safety distance of regulation, in case front truck slows down or anxious stopping, often is difficult to the rear-end collision of imagining.Therefore, no matter vehicle ' is at express highway or low speed highway section (particularly express highway), when the crucial moment that vehicle need slow down or brake, lighting the braking indicator lamp as early as possible, to send early warning information to pursuit-type vehicle obviously be very necessary: but that traditional braking indicator lamp is failed when chaufeur is found the place ahead situation in the first reaction action is shinny immediately, must be in that to implement the brake operating period just shinny after depressing brake pedal.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of rear-end collision method for early warning and device thereof that makes vehicle afterbody braking indicator lamp send early warning information ahead of time to pursuit-type vehicle is provided.
In order to address the above problem, rear-end collision method for early warning of the present invention is to realize with following technical scheme: this method is to utilize chaufeur to find that in the middle of vehicle ' the place ahead has extraordinary circumstances to slow down or first reaction of glancing impact is moved, tailstock braking indicator lamp is begun the shinny time be arranged on pine tar deceleration-operation period of chaufeur, make braking indicator lamp switch on before chaufeur is implemented the foot brake operation time period shinny in advance, send early warning information to pursuit-type vehicle early.
Rear-end collision prior-warning device of the present invention is made up of acceleration pedal, braking indicator lamp and the early warning switch that is arranged on the fuel feeding maneuvering system, the switching state of early warning switch be before chaufeur does not depress brake pedal, demand working when acceleration pedal up unclamps, thereby make the braking indicator lamp shinny in advance before the foot brake operation time period.
Described early warning switch, the position of its installation be one can be with the acceleration pedal combined operation, as long as decontrol or can make to put one's foot down this switch connection or open circuited position.
Compared with prior art, the invention has the beneficial effects as follows: can make tailstock braking indicator lamp shinny immediately in the very first time that chaufeur discovery the place ahead extraordinary circumstances need be slowed down or brake, need not to enter by the time the foot brake operation time period depresses behind the brake pedal just shinny, make the early warning information of this car be found that by first pursuit-type vehicle spacing of discovery is far away ahead of time; And the vehicle that the rear is trailed continuously takes foresight to slow down or brake measure in succession early, keeps a safe distance, thereby avoids or reduce vehicle rear-end collision or the chain of rings major accident that knocks into the back takes place.The present invention compares with existing safety air bag, the latter be before after accident takes place, robbing several seconds zero point protect the people, and the present invention does not do sth. in advance pre-convoy car before the generation as yet in accident.Existingly rescue in imminent dangerly afterwards, just more the essentiality that is taken preventive measures in advance in moment should be arranged in the essentiality of moment; The former is the passiveness defence to personal safety, and the latter is the positive defence to car load safety.
