What is ACC (Adaptive Cruise Control)?
Adaptive Cruise Control automatically adjusts to the speed of the vehicle and precedent, when the road is clear, reaching speeds up to cruising speed selected. Adaptive Cruise Control (ACC) technology improves upon the function of standard cruise control by automatically adjusting the vehicle speed and distance to that of a target vehicle. ACC uses a long range radar sensor to detect a target vehicle up to 200 meters in front and automatically adjusts the ACC vehicle speed and gap accordingly. ACC automatically decelerates or accelerates the vehicle according to the desired speed and distance settings established by the driver. As per standard cruise control the driver can override the system at any time.
The ACC system automatically transitions between Speed Control and Time Gap (Follow) Modes. The mode of operation is determined by the lower of the set speed for Speed Control Mode and the target speed to maintain the gap between the ACC vehicle and a forward vehicle. Basically, if no vehicle is present within the clearance distance, the system will operate in Speed Control mode, else, it will operate in Time Gap mode. ACC equipped cars marginally increase free and dynamic capacity, leads to a drastic reduction of traffic congestion, reduction in stress & rear-end crash risks, decreased lane changes and longer following distances for younger drivers.
One in eight Americans is 65 or older, and this proportion will continue to grow as the American population ages. It is possible that new technologies such as ACC can assist older drivers to drive more safely with less stress, thus extending their safe driving years.
