BACKGROUND OF THE INVENTION
Field of the Invention
This invention is in the field of the avoidance of auto accidents. Most recent auto accident devices are for protecting the driver and passenger after an accident has occurred, such as seat belts and air bags. Horns and brakes have been on cars since their conception for avoiding accidents, but other accident preventive devices have not been introduced and added to autos. Other items that help reduce auto accidents are running headlights and day
ight mirrors to take the glare off of the mirror. Reflectors and light-colored cars make them more visible at night, but they do not prevent an accident from happening by an inattentive driver. In the present invention, a warning sound may automatically occur and if that is not enough, blasts of high pressure air occur to both slow down one's vehicle and help push the other vehicle out of the way, so that even if a collision were to occur, the impact would be less severe than otherwise it might have been.
SUMMARY OF THE INVENTION
With today's high traffic and high speed auto travel conditions, attention needs to be given to collision avoidance as well as collision warning devices.
To avoid collisions between two light-weight autos, sensors with calculators may be used to measure the distances between the autos traveling on the road and their relative speeds to each other. To avoid a collision, the time for impact between the two autos is computed. In the automatic system, if the time falls below a pre-determined value, a relay closes a circuit, applying voltage to one or more solenoid-operated air valves. The energized solenoids open their valves, allowing blasts of air to be emitted at their outlet ports. The blasts of air perform two functions—one to slow down the auto with the devices and two, to push the other vehicle in front ahead or forward so a collision would not occur. Simultaneously, the driver of the first auto could slam on his brakes to first slow down his auto. If a collision should occur, it now would be a softer impact than if the system were not in operation. In case the driver wishes to by-pass the speed and distance sensors with their calculators, he may do so by closing a switch manually, thus causing blasts of air to occur immediately.
In addition, the driver of the first car may be concerned about a rear-end collision from an auto overtaking his own car from the rear, then he could blow his rear-end car horn, as a warning, while also causing blasts of air to occur at his auto's rear-end, thus helping to prevent his car from a rear-end collision. At night, he could turn on rear red headlights, to warn the car speeding toward him that blasts of air will be blown at the approaching car to either avoid a collision or soften the collision, if inevitable. As many of these collision avoidance devices as desired would be installed in cars for owners wishing to have the ultimate in safety equipment, even if the auto's appearance may be impaired by the devices.
