Abstract

The utility model relates to an automobile rear-end resisting device based on vision analysis, wherein a micro-processor (2) is respectively connected with a vision sensor (1), an audible alarm unit (3), a signal collecting unit (5), a display unit (4), and a brake lamp control unit (6). The device monitors vehicles in front of vehicle driving driveway through the vision sensor at any time, measures and calculates the distance between vehicles, and collects the speed, the brake and the steering signals of the vehicle, through the integral analysis, the device calculates the time that the vehicle collides with the vehicle in front thereof as current speed, when the time is reduced to a value which can sufficiently cause a collation, or though the time can not cause the collation but the time is too short, drivers likely adopt the brake action by reason of accidents, at the moment, the system automatically lights the brake lamp, and enables the brake lamp to flicker to remind vehicles on the back of vehicle to notice, if the driver steps the brake, the brake lamp is light all the time, if the distance between vehicles restores to normal, the system closes the brake lamp.

Description

A kind of automobile anti-rear end collision device based on visual analysis
Technical field
The utility model relates to the anti-device that knocks into the back most of a kind of automobile, particularly a kind of automobile anti-rear end collision device based on visual analysis.
Background technology
Along with the quick growth of China's economic, automobile pollution increases in the annual speed with millions of of China.Accordingly, the driver is no longer professional, and the unskilled fresh driver of many driving technologies holds inaccurately to the situation of vehicle front, anticipate not good enoughly, often brings to a halt under normal situation, and the human pilot of front vehicle is caught unprepared, and causes and knocks into the back.Also there are not a kind of performance, the gratifying automobile anti-rear end collision device of price at present.
The utility model content
Technical problem to be solved in the utility model is, a kind of automobile anti-rear end collision device based on visual analysis is provided, vehicle distances when vehicle and front is close to certain distance, when the driver has the brake tendency, make the brake lamp flicker in advance, remind the human pilot of back vehicle to note, avoid when vehicle brake, knocking into the back.
The technical measures that the utility model is taked are: a kind of automobile anti-rear end collision device based on visual analysis, comprise microprocessor unit, vision sensor, audible alarm unit, signal gathering unit, display unit and brake lamp control module is characterized in that: microprocessor unit is connected with vision sensor, audible alarm unit, signal gathering unit, display unit and brake lamp control module respectively.
Microprocessor unit links to each other with vision sensor by the CAN bus.
Good effect of the present utility model is: the vision sensor on the device can be monitored the vehicle in the place ahead at any time, by certain algorithm computation spacing, the actual travel speed of signal gathering unit collection vehicle, signal such as brake whether, obtain whether the danger of knocking into the back is arranged by computing with front truck, when having knock into the back dangerous, human pilot is not still taked brake, mean that human pilot will emergency brake, system will light brake lamp automatically, make its flicker, be about to emergency brake to remind this car of back vehicle human pilot, ready, interim when really bringing to a halt, avoid the generation of rear-end collision.

Described vision sensor 1, be responsible for road ahead information is carried out image acquisition, and carry out graphical analysis, find the vehicle that travels in the place ahead, and calculate the spacing of Ben Che and front vehicles, and communicate by letter signals such as the speed of acquisition vehicle, brake with microprocessor unit 2 by the CAN bus according to certain computing method, carry out analysis-by-synthesis, draw whether to exist and pass to microprocessor unit 2 with the dangerous of preceding vehicle collision and by the CAN bus.
As shown in Figure 2, described microprocessor unit 2 is by various signals such as signal gathering unit 5 collection vehicle speed, brakes.And link to each other with vision sensor 1 by the CAN bus, information such as the speed of vehicle, brake are delivered to vision sensor 1, and obtain and the risk of collision of preceding vehicle from vision sensor 1.Control display unit 4 carries out the demonstration of information and warning, reminds human pilot to note by the audible alarm unit, and makes the brake lamp flicker by brake lamp control module 6, reminds back vehicle to note, is about to brake and avoids knocking into the back.
Described audible alarm unit 3 is subjected to microprocessor unit 2 controls, sends the different sounds, represents various warning, reminds the vehicle drive personnel to note.
As shown in Figure 3, described signal gathering unit 5, directly be connected with the circuit of automobile, detect the speed pulse signal of vehicle, obtaining the speed of vehicle through microprocessor unit 2 computings, is that the signal that can use of microprocessor unit 2 is for microprocessor unit 2 uses simultaneously with signal transition such as the brake of vehicle, headlights.
Described display unit 4 is a kind of display circuits, is subjected to microprocessor unit 2 controls, shows various information, comprises information such as warning level, fault, spacing.
As shown in Figure 3, described brake lamp control module 6 is brake lamp flicker control circuits, is subject to processing 2 controls of device unit, and cooperates the control brake lamp with former brake lamp signal.
