Drunk Driving Prevention Of New Research Of Passive Entry&Passive Start System

In recent ten years, as people living standard enhancement and the wrong pursuit ofautomotive safety comfort, automobile electronic technology has entered a rapid developmentstage. The car keys, experiencing from mechanical to electronic, contact to a major shift innon-contact, keyless start system (PEPS system) is the key system at the present stage, thehighest technical content, with the system, the owner can put the keys in the backpack, whenowners near the door, can realize the automatic open the door, entered, click the Start/Onbutton to ignite the engine and start the car, when the driver of the vehicle flameout leaves,only need to click on the door handle switch when the door is closed, the whole process canbe realized to lock the door, the owner does not need to use the key, advanced function torealize the true meaning of the keyless, non contact.Drunk driving, drunk driving, has always been a topic of concern throughout society, inrecent years, the traffic police department have been efforts to eliminate drunk driving anddrunk driving, but because the current measures are ex post monitoring, not from thefundamental source of wine driving and drunk driving is suppressed, So we see or hear everyday most of the traffic accidents caused by drivers’ fluky psychology.This thesis is based on the two hot mentioned above, a new concept is proposed, for thefirst time the alcohol detection system and keyless start system for seamless integration, it canrealize the keyless start, but also to eliminate the root causes of occurrence of drunk drivingand drunk driving. According to the survey, the global auto market has not this kind ofproduct, it is necessary to carry out research and analysis of seamless integration of twosystem.The proposed new system mainly uses the following techniques: RSSI (Received signalstrength indicator) wireless location technology, VKSP (Variable Key Security ProtocolReceiver) variable key security protocol, fingerprint type alcohol detection technology. First,study on the fingerprint of alcohol detection technology and international front is analyzed,finally the key design of the seamless fusion strategy keyless start system and alcoholdetection system. Because the system is a new concept, simulation results shown that thesystem is feasible.
