Aforementioned, ACC is divided into two systems: laser – based and radar – based. Laser – based systems are relatively lower in cost compared to radar – based systems. The Radar – based ACC systems can detect and track vehicles well in adverse weather conditions and even they can track extremely dirty (or non-reflective) vehicles very well but the laser – based systems can’t. In laser – based systems even while they are activated, the driver is still responsible for monitoring the car’s speed and the distance from the vehicle ahead. Radar – based system also has Pre – crash system and even, applies brakes in high risk of collision and also, features lane maintaining system and reduces the burden over power steering. However, any type Of ACC does react to approaching vehicles or stationary objects. It can be used in busy lanes and in traffics.
