Abstract

In the vehicle running process, whether the front vehicle decelerates or brakes or not can not be judged in time, so traffic accidents such as vehicle rear-end accidents and the like are generally caused, and casualties or property loss are caused. A vehicle active anti-corrosion intelligent warning device can calculate the shortest brake distance by using an ultrasonic distance measuring sensor and a speed sensor, in addition, a central processing unit used for judging whether the variation speed rate reaches a threshold value or not is built, and the warning device promotes a driver or sends out signals such as flickers lamp light flickering and the like to warn the rear vehicles when the variation speed rate exceeds the specific threshold value, so the occurrence probability of traffic accidents is reduced to the furthest degree.

Description

Vehicle is the intelligent alarm device of anticollision initiatively
Affiliated technical field
Along with rapid development of national economy, automobile is being that increasing people uses.The thing followed is, the annual quantity of personnel that caused by traffic accident and property damage is all quite surprising.Therefore, the vehicular drive safety problem has become one of key issue that people pay much attention to day by day.Data according to incompletely statistics, the accident occurrence cause above 80% are what the not timely reaction of driver caused, and the collision case more than 65% belongs to the rear-end impact situation.Analysis shows, if the driver can do sth. in advance to judge the sign of accident in 1 second, and takes appropriate measures, and just can avoid rear-end collision and 60% head-on crash accident more than 90%.
Vehicle of the present invention is collision prevention device initiatively, can shift to an earlier date the brake of phonetic warning chaufeur apart from braking inadequately, also can be widely used in the safety traffic purposes of various vehicles according to the anti-function that knocks into the back of car after the big or small warning in advance of the speed of a motor vehicle and spacing.
Background technology
The vehicle initiatively technology of collision prevention device is an initiatively crashproof safety method of a kind of vehicular drive.When cruising, this device is in readiness for action always.When the distance of front and back vehicle less than normal braking apart from the time, this device will send the voice suggestion that please brake and also start to the anti-simultaneously LED warning signal that knocks into the back of driver, to avoid taking place rear-end collision.
Summary of the invention
In order to improve reaction time and the speed that preventing collision of vehicles hits, device according to the invention can provide a kind of collision-proof method and corresponding central processing unit that can realize front and back vehicle synchronous reaction.
The technical solution adopted for the present invention to solve the technical problems is: adopt MULTISENSOR INTEGRATION information fusion technologies such as ultrasonic distance sensor, car speed sensor, the rate of change of intelligent decision vehicle ' parameter.If surpass the threshold values that the device in house software is set, then start warning signal, prompting car retardation or brake, the crash-avoidance accident takes place.
Innovative point of the present invention is to adopt the multiple sensors combination to use, and realize that multiple vehicle ' parameter information merges; Adopt intelligent CPU hardware calculate platform, improve the speed of response of device greatly.Adopt independently developed Matlab software to set up critical vehicle alarm spacing, can significantly improve the alarm accuracy rate of device.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.Fig. 1 is a structure principle chart of the present invention
As shown in the figure, 1. vehicle, 2. leading vehicle distance sensor, 3. back spacing sensor, 4.LED Warning light, 5. speed sensor, 6. central processing unit.
The specific embodiment
The active collision prevention device that vehicle (1) is installed adopts ultrasonic ranging sensor (3); Speed sensor (5); Whether the shortest braking distance that high speed central processing unit (6) real time operation draws vehicle front and back car reaches threshold values, can shorten the real-time of system greatly.Warning signal triggers judgment models and adopts independently developed MATLAB software program to calculate the criticality safety spacing.Device is provided with rang sensor (2), and its input end connects high speed central processing unit (6), and mouth slows down or brake with the prompting chaufeur with voice.Pass to LED Warning light (4) to warning signal with wireless mode equally, receive the alarm triggered signal after, form the wigwag of fast blink, to the front vehicle prompting that gives a warning.

Claims (5)

1. one kind can be used in the initiatively intelligent alarm device of anticollision of vehicle; Its principal character is that device adopts the high speed central processing unit; The data that provide through rang sensor and speed sensor calculate minimum brake distance fast, and through phonetic warning and LED alarming lamp prompt chaufeur or back car chaufeur.
2. vehicle according to claim 1 is anticollision intelligent alarm device initiatively; It is characterized in that the data intelligence that central processing unit provides through rang sensor and speed sensor judges fast whether rate of change reaches threshold values, and advantage is to shorten greatly the real-time of system.
3. according to claim 1,2 described vehicles are anticollision intelligent alarm device initiatively, it is characterized in that the warning signal triggering judgment models of device adopts independently developed MATLAB software program to calculate the criticality safety spacing.
4. according to claim 1, the anti-intelligent alarm device that knocks into the back of 2,3 described vehicles is characterized in that device is provided with the ultrasonic ranging sensor, and its input end connects the central processing unit of high-speed CPU, and mouth connects the anti-Warning light that knocks into the back of independent LED.After receiving the alarm triggered signal, opto-electronic pickup passes the signal along to the LED Warning light, forms the wigwag of fast blink, to the front vehicle prompting that gives a warning.
5. according to claim 1, the anti-intelligent alarm device that knocks into the back of 2,3,4 described vehicles is characterized in that the high-speed radio transmission, and the system that makes installs simple, easy to operate, and muddy water road surface, different road conditions function setting such as ice and snow road are arranged normally.
