US 11,230,286 B2 · System and method for inspecting vehicle lane keeping performance

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.

Dependent claims

A system for inspecting vehicle lane keeping performance, wherein the system inspects a lane following assist function and a lane keeping assist function of a vehicle during driving of the vehicle, the system comprising:

an on-board diagnostic device that is connected to a controller of the vehicle via controller area network communication to receive driving information according to operation of the vehicle;
and
an inspection terminal, which is installed in the vehicle, configured to:
communicate with the on-board diagnostic device via short-range wireless communication,
measure position information of the vehicle on a map of a road during a running test of the vehicle using a precision global positioning system,
receive the driving information from the on-board diagnostic device to determine whether the lane following assist function operates normally when the vehicle approaches a line of a lane beyond a centerline of the lane or to determine whether the lane keeping assist function operates normally when the vehicle departs from the lane, and
control the vehicle to move into the lane by applying a steering signal to the vehicle when at least one of the lane following assist function or the lane keeping assist function does not operate normally.

A method for inspecting vehicle lane keeping performance of an inspection terminal which is installed in a vehicle and inspects a lane following assist function and a lane keeping assist function of the vehicle during a road running test of the vehicle, the method comprising steps of:

a) connecting, by the inspection terminal, short-range wireless communication with an on-board diagnostic device that is installed in the vehicle when a power of the inspection terminal is turned on, and measuring the vehicle position information on a map of a road using a precision global positioning system;
b) determining, by the inspection terminal, that the vehicle enters an inspection section when the vehicle crosses over a virtual inspection start gate set on a lane so that the inspection terminal collects driving information of the vehicle from the on-board diagnostic device;
c) determining, by the inspection terminal, whether the lane following assist function operates normally when the vehicle is off a centerline of the lane and approaches a line of the road;
d) determining, by the inspection terminal, whether the lane keeping assist function operates normally when the vehicle departs from the lane;
and
e) controlling, by the inspection terminal, the vehicle to move into the lane by applying a steering signal to the vehicle when at least one of the lane following assist function or the lane keeping assist function does not operate normally.
