System and method for automatically controlling vehicle speed

摘要

A system and method for automatically controlling the speed of an automotive vehicle holds the vehicle speed constantly at a set vehicle speed when there are no other vehicles in front of the vehicle and controls the vehicle speed so as to follow another vehicle moving in front of the vehicle according to the distance between the two vehicles. The system disables both of the above-described functions when the vehicle speed is outside of a predetermined speed range around a set vehicle speed after the leading vehicle is no longer in front of the vehicle or a predetermined interval of time after the other vehicle has disappeared from a front detection area.
