Abstract

The invention belongs to the field of the automatic control of automobiles, and particularly relates to a vehicle rear-end collision preventing device. The vehicle rear-end collision preventing device comprises a detection sensor, a GPS (global positioning system) navigator, a central processor, a road condition display device and an automatic controller; the detection sensor is mainly used for transmitting detected barrier information of a front road section to the central processor inside a vehicle, the GPS navigator is also installed inside the vehicle, the central processor is used for analyzing and processing the front barrier information transmitted by the detection sensor and an instant road section diagram inputted by a GPS navigation map and supplying the processed road condition information to a driver through the road condition display device; when the road condition information cannot be processed by the driver in time or is improperly processed by the driver, the vehicle continuously runs towards a barrier, the central processor can transmit a command to the automatic controller so as to automatically operate a brake device to brake in time, and the rear-end collision accident can be prevented. By adopting partial technological means of a pilotless vehicle, rear-end collision and even various accidents can be conveniently prevented by adding the simple device to an ordinary vehicle; the device is simple, convenient to operate, easier to popularize, low in price and wide in market prospect.

Description

A kind of Vehicular rear collision preventing device

Technical field

The invention belongs to automobile and automatically control category, particularly a kind of Vehicular rear collision preventing device.

Background technology

All over the world, on express highway, the rear-end collision accident causing because of foggy weather often has generation, the chain of rings even occurs and knock into the back, and several tens at least, tens are hit together at most, so tragic that one cannot bear to look at it.Trace it to its cause, be mostly because foggy weather etc. causes navigating mate unclear to the identification of front road conditions, due to dealing with improperly.

World many countries all development intelligence or even intelligent car, this class automobile, by multiple high-tech means, not only can be identified dense fog, prevents from knocking into the back, also can be at many complicated highway sections automatic running even in the street.But some section is too complicated, various vehicles, pedestrian, observe order, do not observe order, also have the generation of various unforeseen circumstancess, intelligent car need to take too many emergency case into account, therefore at present also in the research experiment stage, the rare vehicle that appears on the market, even if there is a small amount of vehicle to appear on the market, also because of complex structure, expensive, cannot popularize at present.

For the rear-end collision accident causing because of foggy weather, up to the present, also there is no in the world very good terms of settlement, many express highways are often because dense fog is closed.

Summary of the invention

The object of the invention is to install additional simple mechanism in common vehicle, just can point out navigating mate to take measures or self-actuating brake, avoid rear-end collision.

The present invention, for achieving the above object, takes following scheme: Vehicular rear collision preventing device comprises acquisition sensor, GPS navigation, central process unit, road conditions telltale, the compositions such as auto mat; Acquisition sensor is contained in before vehicle, mainly that section, the front complaint message detecting is passed to the central process unit of device in car, GPS navigation is housed in car simultaneously, the instant section diagram of the front complaint message that central process unit is come in acquisition sensor transmission and the input of GPS navigation map is carried out analyzing and processing, and by road conditions telltale, traffic information after treatment is prompted to chaufeur, chaufeur, because dense fog etc. is former thereby recognize unclear front information of road surface, comes into view by road conditions telltale; The distance of the front road barrier that chaufeur can show according to road conditions, dynamically takes measures, or slows down, or detours, or brake; Fail to process in time or deal with improperly when chaufeur, vehicle continues to drive towards obstacle, central process unit can vehicle and obstacle approach safety shut-down apart from time, order auto mat, to drg automatic operation, brakes in time, prevents that rear-end collision from occurring.

Described acquisition sensor can be super sonic, laser or microwave.Acquisition sensor respectively fills one in the front both sides of car, becomes a triangle with front obstacle, and the not only distance of detection and obstacle, also has the data such as angle, passes in the lump central process unit; Described auto mat is only connected with drg, is receiving after central process unit instruction, and operational brake brakes.

The beneficial effect of Vehicular rear collision preventing device of the present invention is:

One, the part technological means that adopts intelligent car, makes common vehicle increase simple device, has just reached and has prevented from knocking into the back even various collision cases.

Two, because device is simple, easy to operate, be easier to promote, another because device is simple, thereby cheap, more there are market outlook.

Accompanying drawing explanation

Fig. 1, Vehicular rear collision preventing device schematic diagram.

The specific embodiment

Shown in Figure 1: Vehicular rear collision preventing device of the present invention is by acquisition sensor 1, GPS navigation 2, central process unit 3, road conditions telltale 4, auto mat 5 compositions such as grade, acquisition sensor 1 respectively fills one in vehicle front both sides, and be connected with the central process unit 3 of device in car, mainly that section, the front complaint message detecting is passed to central process unit 3, GPS navigation 2 is housed in car simultaneously, the instant section diagram that the front complaint message that central process unit 3 is come in acquisition sensor 1 transmission and GPS navigation 2 are inputted is carried out analyzing and processing, and by road conditions telltale 4, traffic information after treatment is prompted to chaufeur, the distance of the front road barrier that chaufeur can show according to road conditions, dynamically take measures, or slow down, or detour, or brake.When chaufeur fails to process in time or deal with improperly, vehicle continues to drive towards obstacle, central process unit 3 can vehicle and obstacle approach safety shut-down apart from time, order auto mat 5 is to drg 6 automatic operations, brake in time, prevent that rear-end collision from occurring.

Claims

1. a Vehicular rear collision preventing device, by acquisition sensor, GPS navigation, central process unit, road conditions telltale, auto mat composition, it is characterized in that: acquisition sensor is contained in before vehicle, mainly that section, the front complaint message detecting is passed to the central process unit of device in car, GPS navigation is housed in car simultaneously, the instant section diagram of the front complaint message that central process unit is come in acquisition sensor transmission and the input of GPS navigation map is carried out analyzing and processing, and by road conditions telltale, traffic information after treatment is prompted to chaufeur; Vehicle drive towards obstacle approach safety shut-down apart from time, central process unit order auto mat is to drg automatic operation, in time brake.

2. according to a kind of Vehicular rear collision preventing device described in claims 1, it is characterized in that: described acquisition sensor can be super sonic laser or microwave; Acquisition sensor respectively fills one in the front both sides of car, becomes a triangle with front obstacle, and the not only distance of detection and obstacle, also has the data such as angle, passes in the lump central process unit; Described auto mat is only connected with drg, is receiving after central process unit instruction, and operational brake brakes.
