PURPOSE: A controlling method of obstacle detection around a trailer is provided to improve the detection efficiency of obstacles by enlarging detecting and warning ranges of the obstacles. CONSTITUTION: A controlling method of obstacle detection around a trailer includes the following steps: a trailer at the lateral rear side of a vehicle is verified under a surrounding vehicle detecting mode; if there is no trailers at the lateral rear side of the vehicle, a normal detection and warning range is set(S107); and if there is a trailer at the lateral rear side of the vehicle, a trailer detection and warning range which is enlarged from the normal detection and warning range is set(S108). [Reference numerals] (AA) Start; (S101) Entering into a surrounding obstacle detecting mode; (S102) Self analysis; (S103) Failure?; (S104) Entering into a failure mode; (S105) Driving speed of a vehicle is more than or equal to 30KPH?; (S106) Trailer is detected?; (S107) Entering into an ordinary mode; (S108) Entering into a trailer mode; (S109) Detecting an obstacle within a pre-set range; (S110) Obstacle is detected within a pre-set range?; (S111) Lane turning signal operates to an obstacle position?; (S112) Generating a warning about the obstacle to a driver |
