Abstract

An apparatus and method for controlling steering of an autonomous vehicle are disclosed. The apparatus may include: an electric power steering apparatus module configured to generate an assist torque assisting rotation of a steering wheel; an automatic driving position control unit configured to control a steering position according to the commanded steering angle; a driver steering intervention determination unit configured to determine whether a driver intervenes steering; a weight detection unit configured to detect a weight for integrating an output of the electric steering device module and an output of the automatic driving position control unit according to a determination result of whether the driver intervenes in steering; and an output control unit configured to apply a weight to an output of the electric power steering device module and an output of the automatic driving position control unit, thereby generating a final output. According to the device and the method, the steering difference feeling occurring in the mode conversion process from the automatic driving mode to the manual driving mode when driver steering intervention exists in the automatic driving process is improved.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2020-0107116 filed on August 25, 2020, which is incorporated herein by reference in its entirety for all purposes described herein . technical field [0003] Exemplary embodiments of the present disclosure relate to an apparatus and method for controlling steering of an autonomous driving vehicle, and more particularly, to an apparatus and method for controlling steering of an autonomous driving vehicle, which improve the A sense of steering differential during mode transitions from automated to manual driving modes in the presence of driver steering intervention. Background technique [0004] The vehicle's power steering is a power-based steering device used to assist the driver in operating the steering wheel. Such power steering mainly uses hydraulic pressure, but recently, electric power steering (motor driven power steering (MDPS)...
