LANE RECOGNIZING METHOD CAPABLE OF IMPROVING THE ACCURACY OF LANE RECOGNITION BY COMPARING VIRTUAL LANE INFORMATION WITH CURRENT LANE RECOGNITION INFORMATION BASED ON PAST LANE RECOGNITION INFORMATION

摘要

PURPOSE: A lane recognizing method is provided to improve the performance of a safety device such as an LKAS(Lane Definition Warning System) or an LDWS(Lane Keeping Assist System) by improving the accuracy of lane recognition.;CONSTITUTION: A control unit recognizes a current lane from photographing data(S102). The control unit calculates reliability and lane information(S103). The control unit calls stored past lane recognition information and vehicle driving data(S104). The control unit predicts virtual lane information(S105). The control unit compares the virtual lane information with the recognized lane information(S106). The control unit determines the final reliability of the recognized lane(S107).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S101) Lane recognition system ON; (S102) Recognizing a current lane; (S103) Calculating and storing recognized lane information(lane width/lane direction and angle/curvature) and reliability; (S104) Calling a past lane recognition information and vehicle behavior data(yaw rate/steering angle etc.); (S105) Predicting virtual lane information(average lane width/lane direction and angle/curvature); (S106) Comparing the recognized lane information and the virtual lane information; (S107) Determining and storing the final reliability of the recognized lane; (S108) LDWS/LKAS control
