Adaptive Cruise Control automatically adapts the vehicle speed to maintain safe distance from the vehicle in front.

ACC can accelerate and brake a car autonomously. With the help of a radar sensor, camera or lidar, the system maintains both the driver’s chosen speed and a programmed safe distance to the vehicle in front. This helps drivers reach their destination more relaxed, while the more even driving style saves fuel.

With Stop and Go control over the engine, ACC can stop the car completely and restart the engine once traffic gets moving again after a brief pause.

Some ACC systems allow drivers to specify follow distance, while may also have difficulty in poor weather, tunnels or harsh braking conditions.
