Understanding Cruise Control Systems: Constant-Speed, Adaptive, and Full-Speed Adaptive Explained

In modern vehicles, cruise-control systems range from the basic constant-speed setup that merely holds a driver-set speed, to adaptive cruise control (ACC) that dynamically adjusts speed to maintain a safe gap using radar or camera data, up through full-speed adaptive cruise control (FSRA), which adds stop-and-go capability even in heavy traffic. Each system builds on the last in complexity, cost, and convenience.
