Carbon Monoxide Detector for Automobiles

Abstract

A carbon monoxide detector for making automobiles, vans, SUVs, pickups, and heavy trucks safer by equipping them with an automatically functioning carbon-monoxide detector and early warning system whereupon the presence of a dangerous level of carbon monoxide in the interior of a vehicle will shut off the engine, lower the windows and issue a warning for occupants to leave the vehicle.

Claims

1. A carbon monoxide detector for vehicles including automobiles, vans, SUVs, pickups, and heavy trucks safer, comprising an automatically functioning carbon-monoxide detector and early-warning system, wherein upon detection of carbon monoxide in the interior of a vehicle reaching a threshold level will shut off the engine, roll down windows and issue a warning.

2. The carbon monoxide detector of claim 1, wherein the detector is configured into the design and manufacture of new motor vehicles.

3. The carbon monoxide detector of claim 1, wherein the detector is configured as an add-on, aftermarket accessory for adapting to existing vehicles.

4. The carbon monoxide detector of claim 1, wherein the detector operates electronically, and is incorporated into the vehicle's wiring harness and electrical system.

5. The carbon monoxide detector of claim 1, wherein the warning comprises an audio-visual warning such as a flashing red or yellow or both dashboard light.

6. The carbon monoxide detector of claim 5, wherein the warning further comprises a piercing alarm tone.

7. The carbon monoxide detector of claim 5, wherein the warning further comprises a verbal warning such as: Dangerous Carbon-Monoxide Detected! Exit the Vehicle Now!

8. The carbon monoxide detector of claim 1, wherein the detector is configured to first issue its alarms and roll down the windows, then provide a predetermined interval of time before shutting down the engine.

9. The carbon monoxide detector of claim 1, which is powered by the battery when the vehicle is stationary, and powered by the electrical system when the vehicle is in motion.

10. The carbon monoxide detector of claim 1, wherein the detector resets to battery powered mode after the alarm has occurred and indicates by the cessation of its audio-visual alarms when it was safe to get back into the vehicle.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] FIG. 1 is a schematic view illustrating a carbon monoxide detector, constructed in accordance with the present invention.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present invention is a CO Automobile Detector incorporated into the design and manufacture of new motor vehicles, and/or developed as an add-on, aftermarket accessory that is designed to detect the presence of carbon-monoxide in a vehicle's interior, and to roll down the windows, and shut down the engine, in the event carbon-monoxide has been detected.

[0014] The CO Automobile Detector operates electronically, and is incorporated into the vehicle's wiring harness and electrical system. The CO Automobile Detector itself is situated within the vehicle's interior; and when carbon-monoxide levels reach a specific threshold, the CO Automobile Detector responds in three simultaneous ways: 1) The CO Automobile Detector will trip a switch that shuts down the CO-emitting engine, thus stopping CO gas at its source; 2) The CO Automobile Detector will immediately lower all (electrically operated) windows in the vehicle; and 3) The CO Automobile Detector will emit an audio-visual warning such as a flashing red or yellow dashboard light, along with a piercing alarm tone or perhaps a verbal warning: Dangerous Carbon-Monoxide Detected! Exit the Vehicle Now! At this point, until the engine has cooled and the carbon-monoxide level in the interior dropped to zero, the vehicle cannot be started.

[0015] The CO Automobile Detector will function automatically, powered by the battery when the vehicle is stationary, and powered by the electrical system when the vehicle is in motion. Once the Detector/Alarm sequence has occurred, the CO Automobile Detector resets to battery-powered mode, and indicate by the cessation of its audio-visual alarms when it was safe to get back into the vehicle. And, of course, any activation of the CO Automobile Detector provides a clear and compelling, life-or-death reason to get one's vehicle to a competent mechanic/technician as quickly as possible.

[0016] In an alternative embodiment, the CO Automobile Detector is configured to first issue its alarms and roll down the windows, then provide a predetermined interval of time, such as 20 to 30 seconds of further engine operation before shutdown. This allows freeway drivers, for example, a chance to reach the shoulder of the road before the engine is shut down.

[0017] In the schematic flow diagram illustrated by FIG. 1, the sensor or detector 10 is situated in the interior of the vehicle, (not shown). Element 12 represents when no dangerous level of carbon monoxide is detected. Element 14 represents when carbon monoxide levels have reached a dangerous level. In this situation, an electrical circuit is broken, turning off the engine, represented by element 16, and further sending a signal to the windows, represented by element 22, and to initiate the alarm, represented by element 18.

[0018] No one knows how many vehicles have carbon-monoxide problems, and no one knows how many crashes, which appear to have occurred when the driver fell asleep, have been in fact caused by carbon-monoxide leaks into the vehicles' interior. Carbon-monoxide is tasteless, invisible, odorless, and lethal; and it is also a by-product of the burning of gasoline or diesel in an internal-combustion engine. The CO Automobile Detector not only detects the presence of this silent killer; it also shuts it down at its source, while opening all the windows of the vehicle to bring in lifesaving, fresh air. Clever in conception, thoughtful in design, and lifesaving in its function, the CO Automobile Detector whether incorporated into the design and manufacture of new vehicles and/or developed and produced as an add-on, aftermarket accessory will save lives. Thus, this essential safety system will find a wide and enthusiastic market among the motorists of America and the world.

[0019] Although this invention has been described with respect to specific embodiments, it is not intended to be limited thereto and various modifications which will become apparent to the person of ordinary skill in the art are intended to fall within the spirit and scope of the invention as described herein taken in conjunction with the accompanying drawings and the appended claims.
