Detailed description of the invention

It is specifically described embodiment as shown in Figure 2 as this utility model most preferred embodiment:

Traffic accidents mainly show themselves in that modified line overtake other vehicles, knock into the back, the upper and lower continuous modified line of gate mouth, blow out, violating the regulations Parking, reversing, lorry pendant thing, spontaneous combustion etc., the lighter causes vehicle damage, severe one car crash and group dead group wound.Many accidents are removed Outside most anthropic factor, also it is implicitly present in many objective factors and technological deficiency.

One, physiologic factor

Two coincidence visual angles of people have 124 degree, and the most effectively focus on about 1/5th, i.e. 25 degree.Work as vehicle During traveling, driver must frequently roll the neck and eyeball, and to expand the visual field and angle, the biggest vision dead zone of vehicle is the most more Many, and for front vehicle driving situation, can only be by left and right, the rearview mirror (convex mirror of deformation) of local, vehicle is more Big illuminator is the most, and driver's eyes is the most tired, for coach driver, many in also suffering from compartment Artificial disturbance factor.

According to recent statistics data, more than the 15 years old crowd in the whole nation at present, 80% vision is problematic, in other words, later driving Member 80% is bespectacled, thus can increase again owing to visual problems brings driving safety hidden danger.

With the dolly of speed per hour 100 kilometers, find situation from driver's eyes, judge to brain, then be reacted to brake Braking, about 1.7 seconds physiological response time, and at this moment vehicle has moved ahead 47.2 meters.

Different from vision, the audition of people is poor for the sensation time of a sound based on two ears, judges its sound source side Position, its accuracy and precision are far away from vision, under a driving environment collecting various noise, it is desirable to quickly and accurately After judging car, tucket is from the concrete orientation of left, center, right, is not part thing easily, particularly with lengthening lorry (truck) Or for large tank entrucking driver.

Two, environmental factors

1. taillight vision

The taillight of present vehicle and brake lamp, its brightness index is regardless of ordinary road and highway, and highway Significant interval spacing and brake vehicle distance be more than two times of common road, so driver is for adding the visual effect of distance Come poor than common road；

2. backlight effect

The headlamp of opposing lane, sleet, haze weather wetland is reflective, the refraction of the globoidal glass of driver's cabin and reflection Effect, all can affect the respond of driver；

3. the visual field limits

Turnpike driving person is the relative displacement by vehicle Yu ground, it is judged that self traveling relative with other vehicles Speed, owing to the shape size of dolly and cart differs greatly, is sitting in the driver of dolly, in the face of the tall and big freight in front (afterwards) face Visual occlusion, there is no depth of field sense, it is impossible to judge longitudinal vehicle commander's (or stretching out car foreign goods length) distance, almost become blind driving, right Cannot react in time in emergency case；And for wheel all ratio heavy-duty freight car drivers of little overall height, below vehicle body Cutting and be almost blind area, the radius of turn of front and back wheel differs greatly, and in all rear-end collisions, causes the dead probability of group the highest It is all dilly (see Fig. 4, Fig. 5).

Each traveling driver on a highway is intended to safety trip, understands the traveling meaning of the other side the most each other Figure, just can be effectively prevented from the generation of accident.This utility model is intended to use networking mapping techniques so that certain road section scope Under the display interface of the onboard navigation system of the various driving vehicles in (500～1000 meters), isomorphism state can transmit (manifesting) respectively From coordinate, vehicle, license number, the parameter such as driving trace so that the driver in this region can be for travelling each orientation Vehicle, accomplishes comprehensive understanding directly perceived in advance, in order to reserves enough time and makes burst reply.

Three, vector vehicle library module

Show different, owing to this utility model have employed vector vehicle figure also grand master pattern from tradition automatic navigator body single-point Formula, can pass through the vehicle parameter that vehicle each other transmits the library module carried, the coordinate points of all vehicles is reduced into vehicle Figure gives that screen is integrated to be manifested so that each driver is clear from all vehicles in the range of oneself vehicle 500～1000 meters Dynamically formation, except reequiping vehicle voluntarily, all has the shape size of standard to put vehicle administration office on record (see Fig. 6-1 during all vehicle release To Fig. 6-2, Fig. 7-1 to Fig. 7-4).

Fig. 8 is car vector vehicle side, same track two figure (dolly and lengthening traction engine), and wherein L1 represents the vehicle body of front truck Length, S represents vector distance between two car navigators, and L2 represents the spacing length of rear car.After its relational coordinate established by two cars, System can demonstrate that between two car navigators, vector distance S deducts length of wagon L1 of front truck, just can get the spacing of the two automatically L2 so that front truck driver, while understanding front spacing, " sees " again vehicle and the spacing at rear, it is to avoid step on brake to die, The driver's brake causing front vehicle is caught unprepared, thus avoids rear-end collision to occur.Equally, can hold concurrently when overtaking other vehicles in left and right Turn round and look at the spaces of vehicles in other tracks, left and right rear.

This utility model application vector vehicle figure network image technology, regarding with the third party (taking photo by plane) on isomorphism state screen Angle, allows driver see the front vehicle in front of highway and the travel conditions of rear rear vehicle truly, has an advantage in that:

The most greatly expand the visual field of driver

2. decrease vision and the mental fatigue degree of driver

3. reduce traveling anger road disease and the generation of anxiety neurosis

This is that conventional art means cannot realize, and ensures that traffic safety.

Four, information communication

Owing to front and back driver cannot be carried out the information communication of behavior during running at high speed, rear dolly driver thinks Want piggybacking to overtake other vehicles, it is necessary to first to open steering indicating light, by rearview mirror observe neighboring trace vehicle, deflection neighboring trace pass through headlight bounce flash, Loudspeaker ring, notifies dead ahead vehicle: I to overtake other vehicles！If dead ahead is an overlength car, due to dead angle, he will be unable to see Whether clear neighboring trace front has car and its speed, can overtake other vehicles successfully without him, if there being car, and speed is unhappy (such as traction engine), now this car driver will face two difficult selections, i.e. soon not, not get off slowly again, should be afraid of oneself to knock into the back not People, is afraid of that front vehicle knocks again.More it is a risk that meanwhile, whether dead ahead overlength car driver learns rear Just having dolly to exceed the speed limit, be all unknown number, once this car headstock deviate a bit, owing to radius of turn is excessive, after whipping vehicle body Be enough to the dolly overtaken other vehicles to be wanted to longitudinally collapse.

To this, group's message processing module of driving behavior before and after this utility model setting, dolly is by aobvious in the wings On the premise of display screen confirms that neighboring trace front is without car, when opening overtaking steering lamp, system can be with box formation, simultaneously to surrounding vehicle System maps direction information, and front overlength car receives the (voice message: the front vehicle request of overtaking other vehicles of this information！According to row after) Sail condition, agree to, when dolly is overtaken other vehicles, inform front vehicle with double jump lamp blinking form, agree to overtake other vehicles, same neighboring trace front vehicle Dolly lane change first will predict this car will the information of lane change and slow down, rear dolly is after by dead ahead overlength car, aobvious Show that the flicker of double jump lamp is expressed thanks, method, system also can be sent voice message simultaneously and " thanks！" (see figure 9).

According to f_{Frictional force}=μ_{Coefficient of friction}×P_{Normal pressure}、F_Power=m_Quality×a_Acceleration、E_{Kinetic energy}=m_Quality×v_SpeedFormula, road wet and slippery, vehicle Load-carrying, all can be directly related to the braking distance of highway, and the Travel vehicle that Fig. 8 shows is a variable away from L2, and highway passes It is in certain milimeter number that the spacing of system adjusts, and arranges 200 meters of range finding labellings, and driver controls two car cars by range estimation and experience Away from, but to vehicle condition each other such as: DWCC dead weight cargo capacity, coasting distance quiet, dynamic friction is not well aware of, and this utility model is provided with humidity Sensor and pressure transducer, can regulate according to self and the physical burden number of opponent vehicle and point out having of self voluntarily Effect brake vehicle distance, such as: normal 100 meters of braking distances, wet and slippery sky can point out 150 meters, normal load load number 10 tons, L2=100 Rice, physical burden number reaches 12 ton hours, L2=150 rice, wet and slippery condition, L2=200 rice.For dolly of overtaking other vehicles, system can root According to the data being mapped to, vector vehicle figure (top view) gradual change of the overlength car in front is shown, as according to weight grade gradual change Pale red to dark red, after dolly drives to before overlength car after overtaking other vehicles, away from corresponding 150 meters or 200 meters.

Import person of outstanding talent's car speeds along more and more on a highway now, and slightly grazing, the maintenance cost of its costliness is sufficient for People goes bankrupt or broke, and common in-vehicle driver keep someone at a respectful distance to it, and this utility model can find within the very first time from display screen Come from behind the bold and unconstrained car outside 500～1000 meters, accomplish to dodge in advance, particularly with new hand and female driver.

For person of outstanding talent car driver, this utility model equally avoids many unexpected generations.

In like manner, it is also possible to dodging accordingly quickly through making emergency vehicles, this utility model is provided with distress call , once there is emergency case in system, can press triggering switch, and any vehicle can become emergency vehicles, and the most all vehicles are all Advance notice can be accomplished, in order to concede express passway in time.
