Abstract

An apparatus for controlling an MDPS system may include: a column torque sensor configured to sense column torque applied to a steering column of a vehicle; a vehicle velocity sensor configured to sense vehicle velocity of the vehicle; an MDPS basic logic unit configured to decide a first assist command current for driving an MDPS motor in a manual driving mode of a driver; an autonomous driving control unit configured to decide a second assist command current for driving the MDPS motor in an autonomous driving mode of the vehicle; and a mode switching control unit configured to decide a weight into which the driver's steering intention is reflected, and apply the decided weight to the first and second assist command currents to decide a final assist command current for driving the MDPS motor when the vehicle is switched from the autonomous driving mode to the manual driving mode.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Application No. 10-2018-0128993 filed on October 26, 2018, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an apparatus and method for controlling a motor driven power steering (MDPS) system, and more particularly, to an apparatus and method for controlling an MDPS system that can consider the autonomy of a vehicle Driving mode and manual driving mode to control the MDPS motor. Background technique [0004] The vehicle's power steering is a power-based steering device and assists the driver in operating the steering wheel. Traditionally, hydraulic power steering has been mainly used as power steering. Recently, however, the use of MDPS systems that use the force of a motor has increased. This is because the MDPS system is lightweight, takes up little space and does not require oil changes compare...
