STEERING CONTROL DEVICE

摘要

Disclosed is a steering control device that suppresses response delay to appropriately stabilize a behavior of a vehicle during turning braking. The steering control device includes a steer-by-wire system that controls an actuator (8a) that detects displacement of a steering angle when a steering wheel (2) is steered and operates a turning mechanism that turns a turning wheel separated from the steering wheel based on a detection result; a vehicle yaw angle detector (22a) that detects a yaw angle of a vehicle; a steering angle detector (4) that detects a steering angle of the steering wheel; a turning state detector (53A) that detects a turning state of the vehicle based on the yaw angle of the vehicle; a braking state detector (53B) that detects a braking state of the vehicle; and a yaw angle controller (53C) that controls the actuator to suppress a yaw angle deviation before and after braking when the turning state of the vehicle is detected by the turning state detector (53A) and when the braking state of the vehicle is detected by the braking state detector (53B).
