When there is no preceding vehicle in sight, an ACC-equipped vehicle maintains a constant speed set by the driver, just as in a conventional cruise control (CCC) system. ACC systems control the vehicle speed to follow a driver's set speed closely when no lead vehicle is insight. The block computes optimal control actions while satisfying safe distance, velocity, and acceleration constraints using model predictive control (MPC).
