How do Forward Collision Warning systems work?

Like other safety systems that share identical parts but perform different functions (notably, anti-lock braking systems and traction control), an FCW system is usually paired with an adaptive controller. this is often because both systems make use of a scanning device mounted at the front of the vehicle to live the gap from vehicles before you.

There is a considerable number of the way that FCW systems work, including variations within the method wont to detect potential collisions and therefore how the vehicle prepares itself to prevent or prepares for a collision after an alarm has been activated. Warning systems use radar, a laser, or a camera to detect vehicles ahead, and every one of those systems is briefly described below.


Systems work by emitting radio radiation from the hood of the vehicle. Speed of travel and distance from other vehicles is set by monitoring changes within the Doppler effect of the radio wave1 after it bounces off something and returns to the purpose where it started.



Systems work by emitting infrared irradiation from the hood of the vehicle. When the beam hits another vehicle and reflects its source, laser technology allows the space between the 2 vehicles to be measured. employing a simple mathematical formula, the speed of your vehicle can then be calculated. supported these two pieces of knowledge, the FCW system determines the chance of a frontal collision.



Systems work differently than radar and laser methods. rather than wishing on propagation readings or reflections, this FCW system contains a camera mounted on the front of the vehicle and an electronic image-processor. The camera and image processor are wont to determine the chance of a frontal collision.
