Abstract
The invention discloses a drunken driving prevention device which comprises a steering wheel, an ethanol detection sensor, a telecommunication line, an engine controller and an instrument alarm lamp, wherein the ethanol detection sensor is arranged on the steering wheel and connected with the engine controller and the instrument alarm lamp through the telecommunication line. The invention avoids the occurrence of drunken driving from the source, greatly reduces the drunken driving accident rate, can avoid from being outtricked by a driver in a breath holding manner compared with the traditional authorized drunken driving prevention invention and also prevent vehicle speed dip caused by simply cutting an oil line, and other manners during high-speed driving, thereby effectively avoiding vicious accidents of rear-end, and the like caused by the vehicle speed dip.
Description
Technical field
The present invention relates to a kind of mobile unit, be specifically related to a kind of drinking prevention drive device for automobile.
Background technology
At present vehicle-mountedly prevent that the main implementation of drunk driving equipment is as follows: one, alcohol-detection equipment is installed in car, before car starts as found overproofly, disconnected Starter relay, car cannot be started; Two, alcohol-detection equipment is installed in car, periodically alcohol situation in inspection vehicle, disconnects starter motor relay as exceeded standard, and no matter whether car starts; Three, alcohol-detection equipment is installed in car, periodically alcohol situation in inspection vehicle, as the disconnection oil circuit that exceeds standard, no matter whether car starts.There are the following problems for method one: if drunk driving person by the mode such as holding the breath, the alcohol-detection equipment of can out-tricking, starts automobile normal running.There are the following problems for method two: drunk driving person uses the mode such as hold the breath, and starts after automobile, even if system detects its drunk driving, then turn-offs starter motor, also cannot make car flame-out.Once because of automobile starting, the running of driving engine does not need to use starter motor, therefore whether turn-offs starter motor relay and all cannot make car stop.There are the following problems for method three: if in the car situation that finds that there is drunk driving in service, turn-off immediately oil circuit, return and cause speed of a motor vehicle bust, in the time running at high speed, the various pernicious traffic accidents such as very easily knock into the back, cause that new traffic accident is also worth choosing although controlled drunk driving.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of drinking prevention drive device.
The technical solution used in the present invention is: a kind of drinking prevention drive device, comprise bearing circle, ethanol acquisition sensor, communication line, engine controller and instrument warning indicator lamp, described ethanol acquisition sensor is arranged on bearing circle, and ethanol acquisition sensor is connected with engine controller and instrument warning indicator lamp by communication line.
As preferably, drinking prevention drive device of the present invention also comprises car body controller, stoplight stop lamp and warning lamp, and described ethanol acquisition sensor is connected with car body controller by communication line, and car body controller passes through control path
Be connected with stoplight stop lamp and warning lamp.
As preferably, described communication line is CAN bus.
Drinking prevention drive system of the present invention is mainly used in preventing from driving when intoxicated.Integrated alcohol-detection sensor on this bearing circle, in the time that drunk person drives a car, the alcohol content of bearing circle in breathing by sensor senses driver, judges whether to reach pre-concentration.When alcohol concentration exceedes predefined drunk index, if car is not activated,
Drinking prevention drive system, by CAN bus line command to engine controller, make engine control ignore client in the operation that starts in such cases automobile, driving engine remains and does not rotate, simultaneously by the flicker of CAN bus line command instrument warning indicator lamp, inform that driver, because of drunk, cannot start automobile.If started, drinking prevention drive system will be glimmered by CAN bus line command instrument warning indicator lamp, and have the order engine controller of prompting progressively to reduce the speed of a motor vehicle within the time of setting, until kill engine.Open stoplight stop lamp and trouble lamp by CAN bus notice car body controller, notice proximate vehicle is taken care simultaneously, and the traffic accident such as prevent from knocking into the back under high speed.
Circuit theory of the present invention is: as shown in Figure 2: in the time that alcohol sensor detects alcohol, B, the resistance value that C is ordered can diminish, cause the sample voltage value of the Port mouth of IC to reduce, alcoholic strength reaches predetermined value, the Port mouth magnitude of voltage of IC can be lower than early warning voltage operation voltage, now IC can be by the CAN bus literary composition of transmitting messages, the flicker of control instrument indicator lamp, order car body controller is opened stoplight stop lamp and warning lamp, then by CAN order control unit of engine in the situation that driving engine does not move, do not start or in the situation that driving engine moves, progressively reduce the speed of a motor vehicle, until stop.
Beneficial effect: the present invention has stopped the generation of drunk driving from source, greatly reduce drunk driving accident rate, the drinking prevention drive invention of more existing mandate, can avoid being out-tricked by the mode of holding the breath by driver, also can prevent in the time of high speed, because the simple modes such as oil circuit of cutting off cause speed of a motor vehicle rapid drawdown, the serious accident such as what actv. had been avoided causing thus knock into the back.
