What is ACC?

Adaptive Cruise Control(ACC)  is an automotive driver assistance system that automatically adjusts its speed to maintain a safe distance based on traffic ahead of the vehicle. The system uses sensors such as radar and cameras to detect the vehicle ahead and control acceleration and deceleration based on the detected information Adaptive Cruise uses a variety of sensors to detect traffic ahead. The most common of these are radar and cameras.


Radar is a device that uses electromagnetic waves for detection. In an adaptive cruise system, the radar emits electromagnetic waves and receives the signal reflected back to determine if there is an obstacle ahead. By calculating the time and strength of the reflected signal, the system can determine the distance, size and location of obstacles ahead.


camera is an optical sensor that captures images of the road ahead. In an adaptive cruise system, the camera transmits images to a computer for processing and is used to identify information such as vehicles ahead and road signs.
