Abstract
The utility model discloses a fatigue driving prevention device for an automobile. The fatigue driving prevention device aims at overcoming the defects that the existing fatigue driving prevention device may make erroneous judgment so as to influence the normal driving and the like. The key point of the technical scheme is that the fatigue driving prevention device comprises a microcomputer and an image acquisition unit and an alarm unit which are connected with the microcomputer, and the microcomputer is also connected with a vehicle speed sensor and an engine control system of the automobile. Through the real-time monitoring on the speed of the automobile, the device makes a judgment on fatigue driving only when the speed is higher than a set valve, thus avoiding making erroneous judgment on the fatigue driving since a driver checks the road conditions in a large range during low-speed driving and ensuring the normal driving.
Description
Technical field
The utility model relates to the auto manufacturing technology association area, and in particular, the utility model relates to a kind of automobile anti-fatigue-driving device that whether decision carries out the fatigue driving judgement according to speed of a motor vehicle size.
Background technology
Along with popularizing of automobile, traffic accident has ever-increasing trend, and according to ASSOCIATE STATISTICS, 40%～70% road traffic accident is relevant with the driver fatigue driving, therefore, is necessary very much to develop the warning device that a cover can be differentiated the driver fatigue degree.
The day for announcing is on October 28th, 2009, and notification number is that the Chinese patent of CN101565036A discloses a kind of anti-fatigue-driving device and method, and device comprises image acquisition units, fatigue state diagnosis unit and warning and brake unit.Behind the vehicle launch,, the image that collects is analyzed, and judged whether to be same chaufeur steering vehicle, monitoring driving person's continuous driving time by the graphicinformation of real-time collection chaufeur; Simultaneously, by image processing program the chaufeur image that collects is handled, determine the driver's eyes position, detect the frequency of wink and the eyes of chaufeur and open closed degree, and in conjunction with the driver vision degree of scatter and stare location time-out degree, the driving condition of analysis and judgement chaufeur; When being in fatigue driving state, takes chaufeur to report to the police and brake measure.The monitored control system of the pre-anti-fatigue-driving that this patent provides, erroneous judgement appears easily, when vehicle travels in the urban district, because road conditions complexity, chaufeur is checked road conditions about needing on a large scale, the anti-fatigue-driving device may be gathered the eye situation less than chaufeur like this, causes erroneous judgement, influences normal driving.
The utility model content
The utility model mainly solves existing anti-fatigue-driving device may cause erroneous judgement, influences the technical matters of normal driving; A kind of automobile anti-fatigue-driving device that whether decision carries out the fatigue driving judgement according to speed of a motor vehicle size is provided.
For achieving the above object, the utility model adopts following technical scheme: a kind of automobile anti-fatigue-driving device, comprise microcomputer and image acquisition units that links to each other with microcomputer and alarm unit, described microcomputer also links to each other with car speed sensor, the engine management system of automobile.Microcomputer also links to each other with the car speed sensor of automobile, the speed of a motor vehicle to automobile is monitored in real time, when the speed of a motor vehicle is higher than setting value, just carrying out fatigue driving judges, when judging that chaufeur enters fatigue state, remind chaufeur by alarm unit, still be fatigue state if remind the back chaufeur, then reduce the speed of a motor vehicle, low speed driving by engine management system; When the speed of a motor vehicle is lower than setting value, do not carry out fatigue driving and judge, be fatigue driving, the assurance normal driving with regard to can not be when driving at low speed judging by accident like this because of the checking road conditions on a large scale of chaufeur.
As preferably, described image acquisition units is made up of infradred sensor.When night driving, need not to add in addition external light source, infradred sensor just can be gathered the face image of chaufeur, and adding external light source can influence driver vision.
As preferably, described image acquisition units is installed on the Auto Instrument desk in chaufeur dead ahead.Image acquisition units only is contained in the dead ahead of chaufeur, could gather the face image of chaufeur clearly.
As preferably, described microcomputer comprises MCU, memory device and external interface circuit, memory device all links to each other with MCU with external interface circuit, and external interface circuit links to each other with image acquisition units, alarm unit, car speed sensor, engine management system respectively.MCU is responsible for the operation and the data computing of program, memory stores software program and related data, and external interface circuit is responsible for the data exchange between MCU, memory device and the peripheral hardware.
As preferably, described alarm unit is a phonetic alarm.The information of phonetic alarm prompting is more directly perceived, soft.
The beneficial effects of the utility model: microcomputer also links to each other with the car speed sensor of automobile, the speed of a motor vehicle to automobile is monitored in real time, when the speed of a motor vehicle is higher than setting value, just carrying out fatigue driving judges, be fatigue driving with regard to can not be when driving at low speed judging by accident like this, guarantee normal driving because of the checking road conditions on a large scale of chaufeur.
