Title:
STEERING CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2019130958
Kind Code:
A
Abstract:
To provide a steering control device capable of suppressing generation of vehicle deflection.SOLUTION: A steering control device, which takes, as a control object, a steer-by-wire type steering device having such a structure that a steering section and a turning section are mechanically separated and a turning side motor giving the turning section a turning force as a force of steering a turning wheel, includes a turning control section for feedback controlling the turning side motor so that an angle deviation Δθp of a turning correspondence angle convertable into a turning angle of the turning wheel to a target steering angle set according to steering of the steering section becomes smaller. The turning side control section, when a vehicle is running straight, executes limit processing of limiting a proportional term P and an integration term I obtained based on the angle deviation Δθp of feedback control by a final gain Kf calculated by a lower-limit guard setting section 92 so that the angle deviation Δθp is difficult to decrease more than when the vehicle is not running straight.SELECTED DRAWING: Figure 3
