Abstract:

Every minute, on an average, at least one person dies in a crash. Even the latest advances in the fields of science and technology we have developed safety systems, such as air bags and seat belts, which save tens and thousands of people. But the ultimate solution, and the only one that will save far more lives and limbs, is to keep the cars away from crashing.

Adaptive cruise control {ACC) is an expansion of the existing cruise control systems , which in general maintain the vehicle speed through a link in the vehicle power train. With the help of this ACC, we not only sense the occurrence of a collision, instead we can even minimize the effect of a collision or altogether prevent the collision itself.

Here, we can always maintain a set head way distance between the host & the preceding vehicle. Thus by always maintaining a certain distance between the two vehicles we can avoid the collision. In order to do so, it will control the host vehicle speed by activating the throttle valve or by applying brakes, under the control the processor.

It involves a millimeter wave radar technology that promises to make driving easier. If we are able to incorporate Global Positioning System {GPS} along with adaptive cruise control, then there comes a day where Driverless automobiles will become a reality.
