Adaptive cruise control (ACC) is a driver assistance system that automatically adjusts a vehicle's speed to maintain a safe following distance from the car in front. For instance, when driving on the highway, ACC can help reduce driver fatigue and improve safety by automatically adjusting the vehicle's speed to match the flow of traffic.
ACC is a valuable feature that offers several benefits, including reduced driver fatigue, improved safety, and increased fuel efficiency. Historically, ACC was first introduced in the 1990s and has since become more advanced and widely adopted.
