Title:
STEERING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/127587
Kind Code:
A1
Abstract:
An assist control unit (20) computes an assistive torque command (Ta*) on the basis of a steering torque (Ts). A steering angle control unit (30) computes a steering angle control torque command (Tθ*) so that a steering angle (θ) determined according to the output of a motor (80) is tracked to a target steering angle (θ*) designated in a command from a lane keeping assist device (16). A vibration control unit (50) computes a lane departure warning control torque command (Tv*) to impart vibration to the assistive torque upon notification of a request for activating a lane departure warning from a lane departure warning device (17). A motor drive control unit (65) controls the driving of the motor (80) on the basis of the sum (Tm*) of the assistive torque command, the steering angle control torque command, and the lane departure warning control torque command. The steering angle control unit (30) has a vibration removal filter (40) to remove the vibration frequency component of the lane departure warning as part of the computation in a steering angle signal loop of the steering angle control.
