The specific embodiment

Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.

Main thought of the present utility model is after after drinking driver gets on the bus and shuts car door, after half stroke of insertion key turns makes the vehicle circuit turn-on, whether the alcohol content tester startup that is installed in the bearing circle back exceeds standard with alcohol content in the air in the inspection vehicle, allow start the engine if detect the then vehicle-borne electronic control unit (ECU) that do not exceed standard, the driver is rotated further key and can starts; If detecting overproof need be that the driver breathes out or occupant's exhalation according to reaction time detector differentiation alcohol also then, slowly illustrate then that the driver drinks if detect driver's reaction time, driving engine can't start under the control of ECU, then can start on the contrary.

Fig. 1 is the structural representation of vehicle alcohol detecting device in the utility model specific embodiment.As shown in Figure 1, the vehicle alcohol checking system comprises vehicle-borne electronic control unit 7, alcohol content tester 4, reaction time detector 8 and power supply 9, comprises button and indicator lamp on the reaction time detector.Alcohol content tester is connected with the vehicle electronics control unit respectively with the reaction time detector, and alcohol content tester detects airborne alcohol concentration in the vehicle, and testing result is sent to the vehicle electronics control unit; The reaction time detector detects vehicle driver's reaction time, and the result is sent to the vehicle electronics control unit, and the vehicle electronics control unit judges whether alcohol concentration exceeds standard and reaction time overlength whether.Power supply provides electric power to vehicle electronics control unit, alcohol content tester and reaction time detector.

Except instrument 3, also comprise the reaction time detector on the Vehicular instrument panel 6, the reaction time detector comprises button 1 and indicator lamp 2, and alcohol content tester 4 is positioned at the rear of steering wheel for vehicle 5.

Most of vehicle drivers directly turn to end start the engine after key is inserted key hole, and this is an operational motion improperly in fact, and all there is considerable influence in the vehicle condition and life-span of automobile.Correct way should be elder generation with half stroke of key turns, and at this moment driving engine does not start, just the vehicle circuit turn-on.Almost on every vehicle automatic detection system is arranged all now, vehicle-mounted ECU or can send when several key projects of vehicle are detected " too " sound, electric fuel punp is started working simultaneously, and the petrol feed pump that will be arranged in the car rear fuel tank comes to the fwd driving engine.These two processes carry out being no more than 10 seconds time according to the different general needs of vehicle simultaneously.

Shut after the driver gets on the bus goalkeeper's key turns circuit turn-on after, whether alcohol content tester starts with overproof in the air in the inspection vehicle.Do not illustrate that then nobody drinks in the car if detect, i.e. driver's not excessive drinking certainly.At this moment driving engine allows to start, and waits self check end back driver to be rotated further car key and has got final product start the engine.Must emphasize a bit at this: after driver's sidecar door must being shut after the driver gets on the bus half stroke of key turns just can be entered self check with circuit turn-on,, cause the alcohol content tester erroneous judgement because be not related to the influence that car door may have air flows.So whether car door shuts most of existing vehicle can differentiate and need not again ad hoc for it sensor.In addition, driver's most situation vehicle windows before starting vehicle are all closing, and have just locked door and leave because few people can be not related to vehicle window, so the influence of the wind that need not consider not close vehicle window and produced.

If it is overproof in the air that vehicle-mounted ECU has detected in the car, at this moment have two kinds of situations.The one, driver self excessive drinking and attempt are driven; The 2nd, have the occupant to drink wine in the car, the alcohol that alcohol content tester measures be from occupant's mouth, breathe out and the driver does not drink.The purpose of this utility model be the containment driver drive when intoxicated but must allow drunk wine the occupant by bus.The people has two important reactions after excessive drinking, having what also have the alcohol steam in the air of breathing out is exactly obviously to descend in the reaction time.Whether driver's reaction time can judge normally whether the driver drinks so ECU only need test again.The reaction time detector that is contained on the instrument carrier panel is made up of indicator lamp and button.The driver puts down finger gently on button when voice suggestion " is pressed button " when please seeing that indicator lamp lights, indicator lamp can finish constantly lighting at random in back 5 seconds at voice, moment of lighting of reaction detection instrument moment that can press the button according to the driver and indicator lamp is measured driver's reaction time like this, signal is passed to ECU, if ECU judges the reaction time not excessive drinking of driver normally then is described, driving engine can start, otherwise cannot start the engine.Why allow the indicator lamp in 5 seconds, be not allow the driver know that when bright to record the reaction time the most accurately it is, surpasses 5 seconds and can some lose time again constantly to light at random.

Application of the present utility model can also bring a benefit, want to allow engine starting must be after self-checking system be finished self check work just can, alcohol detection needs several seconds work-hours, conforms to substantially with the self check time.Even before alcohol detection finishes the driver key is forwarded to head also can't start the engine, just want to start and must wait the self check end.Can make the driver form correct startup custom like this, very beneficial to vehicle.In addition, it is to be disinclined to add action so because dislike trouble that many drivers do not wear safety strap, in the time of driving engine self check, wait for some embarrassment, so this also is to cultivate the driver to fasten the safety belt effective time of this good custom, visible the utility model benefit of bringing of achieving many things at one stroke is a lot.

Do not get rid of and can look for a people who does not drink to help him to start vehicle after minority driver excessive drinking is arranged, this thing generally takes place not too easily.At first, the reaction time detector be installed on the instrument carrier panel by driver's car door one side, the occupant who is sitting on co-pilot seat and the back seat reaches, can not help the driver to start smoothly, startup is not ery easy yet so others helps, and this can reduce the probability of looking for the people to help and start to a certain extent.Even if secondly the driver looks for the people, this people can be colleague occupant or passer only.But others can help his probability very low again.Cause severe injury or dead major accident after drinking mainly to occur in night, people are drinking very late after the meal, and colleague's philtrum does not almost drink.So they whom do not start vehicle.Past according to this casualty statistics data show, the driver drinks and the situation that exists the occupant not drink is more rare.Even imagining this situation has taken place, is does having the driver which all there people is ready to have helped to drink wine again start vehicle and oneself served no-return road? the attendant in passer and restaurant generally can not abandon the unreasonable request that morality and justice is carried the conscience of oneself person that promises the drunken driving yet, but takes correct way such as helping that the driver goes by taxi etc.Unless they ignore state's laws, violate the law intentionally.Just not within the protection domain of this device, what device of wanting intentionally to violate the law do not stop that this situation yet.Traffic accident and Probability are closely related, and the utility model can reduce the probability of driving when intoxicated dramatically, keeps more life.It can prevent that not only the driver from driving away car after drinking, can also prevent that the driver from drinking, and some driver knows that the car of oneself is equipped with and just no longer drunk before driving in this device back.

The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with the people of this technology in the disclosed technical scope of the utility model; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
