Claim Text:
1. An apparatus for automatically controlling a vehicle speed, the apparatus comprising: a driver's habit determining unit configured to receive drive data of a vehicle from Electric Control Units (ECUs) provided in the vehicle to determine driver's habits; a speed control time point generation control unit configured to receive the drive data of the vehicle from the ECUs and receive a driver's habit value from the driver's habit determining unit to control a speed of a smart cruise control apparatus; a display/audio control unit configured to guide the driver visually or audibly by using information about a result of controlling the smart cruise control apparatus by the speed control time point generation control unit, the drive data and driver's habit information; and a control result transmitting/monitoring unit configured to monitor the result of controlling the smart cruise control apparatus or drive data generated while the smart cruise control apparatus is operated in order to transmit the controlling result or the generated drive data to the driver's habit determining unit, wherein the driver's habit determining unit includes: an input unit configured to receive the drive data from the ECUs; a rule database including a normalized table by removing an outlier from values received through the input unit, wherein the outlier is a value greater than a preset acceleration or deceleration value; a learning factor calculating part configured to calculate a learning factor from the rule database; a driver's habit calculating unit to calculate a driver's habit value by weighting a learning factor of a road type among learning factors calculated by the learning factor calculating part, wherein the weighted learning factor has a selection frequency value greater than a preset selection frequency value; and a driver's habit database storing the driver's habit value calculated by the driver's habit calculating unit.
