LANE KEEPING STEERING CONTROL METHOD CAPABLE OF USING A VARIABLE LANE DEVIATION TIME WHICH ENABLES A NATURAL STEERING CONTROL, AND AN APPARATUS

摘要

PURPOSE: A lane keeping steering control method capable of using a variable lane deviation time and an apparatus are provided to improve a controlling function by structuring to use different control logics depending on a plurality of lane deviation time threshold value.;CONSTITUTION: A lane keeping steering control method of a vehicle is comprised of a step(312) which receives the left lane information and the right lane information; a step(340) which determines whether a lane width which is generated based on the left lane information and the right lane information is greater than a threshold value; a step(364) which performs an open-loop control and a feed-back control if the lane width is greater than the threshold value; a step(374) which performs the feed-back control without the open-loop control if the lane width is less than the threshold value.;COPYRIGHT KIPO 2013;[Reference numerals] (312) LFT lane information; (314) RGT lane information; (320) Lane compensation logic; (330) Lane width information; (340) Lane width = Lane width threshold ?; (352) Set three TTLCs; (354) Set two TTLCs; (AA) No; (BB) Yes
