Embedded Systems Engineering - Assignment ExampleIf the blood alcohol content (BAC) of the subscribe tor is more than than the defined value, the system locks the ignition disabling he vehicle from starting. For many years the society has experienced drunkard driving as a major(ip) problem which has claimed so many innocent lives apart from just the drunk number one woods. The system not only prevent drunken drivers from driving while intoxicated, b bely also save many innocent lives who may fall victims of drunk driving.

It is highly accurate as compared to t he manual ways of preventing drunken drivers from driving in that it does not the brand the car in case the blood alcohol content is above the defined amount. ... That is, if the level of blood alcohol content is higher than the defined value, therefore the system automatically locks the vehicles ignition preventing the engine from starting.

Objectives A general objective of the automobile breathalyzer ignition interlock system is to prevent drunk drivers who are not fit to drive from driver by automatically locking the cars ignition system unless the drivers BAC value is lower than the defined limit center that the driver is sober enough to drive. Nearly 38% of road accidents are alcohol related while curbing the problem of drunk driving has prove difficult through the use of the other manual ways, the automobile breathalyzer ignition interlock system precludes the possibility of an accident and other incidents related to drunk driving such as revoking offenders licenses altogether. The system should be able to disable the cars ignition system should it be found that the BAC value of the driver is higher than the defined limit depending on the state or country.
