Background Cruise control is a function that maintains vehicle speed without continuous input from the driver. Conventional cruise control systems allow a driver to set a steady speed while driving on long-distance highways, thereby reducing fatigue and fuel consumption. More advanced versions, such as adaptive cruise control, use a radar or camera to adjust vehicle speed based on traffic conditions, improving safety and efficiency.
