Embedded Systems Engineering - Assignment Example If the blood alcohol content (BAC) of the driver is more than the defined value, the system locks the ignition disabling he vehicle from starting. For many years the society has experienced drunk driving as a major problem which has claimed so many innocent lives apart from just the drunk drivers. The system not only prevent drunken drivers from driving while intoxicated, but also save many innocent lives who may fall victims of drunk driving. Executive summary An automated breathalyzer in most countries is fixed in convicted drunken drivers vehicles in order to control the vehicle ignition under the conditions that the driver’s blood alcohol content is from the sample breath is below a certain defined alcohol level. The automated breathalyzer engine ignition switch will act as safeguard ensuring that drunken drivers who are not fit to drive are out of the road. It is highly accurate as compared to the manual ways of preventing drunken drivers from driving in that it does not the ignite 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, then the system automatically locks the vehicle’s ignition preventing the engine from starting. It therefore ensures that drunken drivers who are not fit to drive are eliminated from the road thus prevent accidents. Problem statement Public safety calls for the elimination of drunken drivers from the road in order to reduce accidents mostly related to alcohol. Statistics indicate that about 38% of the road accidents are alcohol related. Loopholes exists in the current system used to test drunken drivers on their ability to drive in that a driver who might be breaking the legal limit for blood alcohol still has the potential to pass the roadside sobriety tests. This is because the roadside sobriety tests such as testing if the drunken driver can walk in a straight line are manually done and their accuracy is quite questionable. 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 car’s ignition system unless the driver’s BAC value is lower than the defined limit meaning that the driver is sober enough to drive. Nearly 38% of road accidents are alcohol related while curbing the problem of drunk driving has proved 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 car’s 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.
