When a slower leading vehicle is present, the ACC controlled vehicle will follow the lead Adaptive Cruise Control (ACC) system has been proposed as an enhancement over existing cruise controllers on ground vehicles. 04.12.2021 | No Comments. Also learn the history it because it's been around in some form since the 1950s. Part C Emerg. 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).
