AUTO CRUISE CONTROL SYSTEM FOR KEEPING DISTANCE BETWEEN CARS

摘要

PURPOSE: A cruise control apparatus for the vehicles capable of maintaining the vehicular gap maintenance, and a method thereof are provided to give drivers a sense of security in case of maintaining a vehicular gap based on the driving of the vehicles, and to enhance a precision for the vehicular gap maintenance. CONSTITUTION: The cruise control apparatus for the vehicles to maintain the vehicular gap with a preceding vehicle by controlling an acceleration/deceleration part accelerating and decelerating a velocity of the vehicle includes a sensor unit(204) detecting a velocity of the vehicle and a vehicular gap with the preceding vehicle; a memory(206), in which acceleration and deceleration patterns based on velocity changes of vehicular gaps between the preceding vehicle and the vehicle are saved; a driving mode setting part(208) establishing a driving mode of the vehicle by comparing the vehicular gap detected from the sensor unit, the velocity of the vehicle and the acceleration and deceleration patterns; and a controller(210) controlling the velocity of the vehicle by controlling the acceleration/deceleration part on the driving mode. The cruise control apparatus more includes a pattern definition part(212), which collects driving information of the vehicle for a fixed time, and updates the acceleration/deceleration patterns saved in the memory. The cruise control apparatus more includes the pattern definition part, which updates the acceleration/deceleration patterns saved in the memory by using information entered by the vehicle drive. The cruise control apparatus more includes the pattern definition part, which updates the acceleration/deceleration patterns saved in the memory by using the acceleration/deceleration patterns of the preceding vehicle. The driving mode setting part compares the velocity of the vehicle, the vehicular gap, and the acceleration and deceleration patterns, and selects one of modes among cost mode, deceleration mode, acceleration mode or free racing mode. When the driving mode is a cost mode, the controller controls an acceleration/deceleration part(202) to maintain the present velocity of the vehicle.
