Abstract
A system for inspecting vehicle lane keeping performance includes: an on-board diagnostic device (OBD) connected to a controller of a vehicle via controller area network communication to receive driving information; and an inspection terminal installed in the vehicle, connecting short-range wireless communication with the OBD, measuring position information of the vehicle on a road using a precision global positioning system, receiving the driving information to determine whether lane following assist function (LFA) function operates normally when the vehicle crosses over a line of a lane beyond a centerline of the lane and to determine whether a lane keeping assist function (LKA) function operates normally when the vehicle departs from the lane, and controlling the vehicle to move into the lane by applying a steering signal to the vehicle when at least one of the LFA function or LKA function does not operate normally.
