System and method for preventing the operation of a motor vehicle by a person who is intoxicated

Abstract

A system and method to prevent a human being from operating a motor vehicle if the human being is intoxicated or under the effects of particular hallucinating drugs that uses a galvanic detector that can measure epidermal (skin) elements of a human being such as alcohol content, sweat and temperature continuously in conjunction with circuitry and logic circuits that connect to the vehicle″s ignition system that only allow the vehicle to be operated when certain temperature sensing conditions are met and certain conditions requiring no alcohol are met otherwise the vehicle will be turned off. In an alternate embodiment, a glove could be used for epidermal measurements that is also connected to the sensing circuits.

Description

BACKGROUND OF INVENTION [0001] 1. Field of the Invention [0002] This invention relates to a system and method that will prevent a human being from operating a motor vehicle if that human being is intoxicated or under the effects of hallucinating drugs. The system includes the use of a galvanic detector that can continuously measure the alcohol or toxicity level of the human being in conjunction with override switches to prevent the motor vehicle from being started or operated after impairment levels of alcohol are detected. [0003] 2. Description of Related Art [0004] Although much progress has been made in the United States of America against drunk drivers in the last decade, drunk driving continues to be the number one factor in fatal automobile and vehicle wrecks in the United States. The deaths, injuries and destruction caused by drunk drivers is totally preventable. Though systems have been devised that disable a motor vehicle based on a driver″s alcohol level, such systems, bec...

AI Technical Summary

Benefits of technology

[0019] If a person were driving that does not have alcohol in their blood that is measured through the trans-dermal alcohol sensing instrument, then the vehicle will operate normally. If the driver constantly contacts and removes his hands from the steering wheel, it will not interrupt the automobile provided it does not exceed its predetermined time limit. One of the features of this device is that for the engine to continue running, there must also be a constant temperature measurement so that someone could not defeat the system by putting on special gloves to avoid detection of alcohol because there must be a human temperature of their hand on the wheel in order for the system to work continuously. However, with the time delay circuit that bypasses the trans-dermal sensing switch activator for short periods, a person can change hands or move their hands about the steering wheel without shutting down the system. For example, it would take 35 to 40 seconds of continuously non-thermal input before the time delay shut off.

[0021] In yet another alternate embodiment, a combination of special gloves and special sensors on the steering wheel could require that the glove and steering wheel interact continuously in order to allow the engine to run so that someone could not try to defeat the system by not wearing the gloves.

[0022] It is an object of this invention to provide an improved system and method for preventing drunk or inebriated drivers from driving an automobile or truck or road vehicle or plane.

[0023] It is another object of this invention to provide a low cost, non-complex system that measures the alcohol level of a driver of a vehicle and interrupts or prevents the automobile from being driven when a particular level of alcohol is detected in the driver.

[0024] And yet still another object of this invention is to provide an alcohol detection system that provides continuous signals during the operation of a vehicle at all times that can measure accurately the alcohol level of the person driving.

Problems solved by technology

Though systems have been devised that disable a motor vehicle based on a driver″s alcohol level, such systems, because of the complexity, have not been employed as too costly or too easy to circumvent.

The complexity of this system, the overall accuracy and the expense would seem to limit its use on a practical level.

The use of breathe analyzers which are not that accurate and which require an initial sensing is not practical for use in conjunction with a vehicle during its operation.

Although the breathe analyzer of this device may be highly accurate, its interaction with a vehicle which requires a person driving to breath into constantly is impractical.

While many of the devices in the prior art attempt to solve the problem of preventing a person who is intoxicated from operating a motor vehicle, the complexity and expense of the units make it impractical for use in present day automobiles and road vehicles.
