VEHICULAR STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vehicular steering device which further stabilizes vehicle behavior by suitably performing vehicle behavior stabilization control. SOLUTION: A turned angle setting part 31 determines a turned angle setting valueδFF* according to an operation angleδh. A turned angle correction value operation part 34 determines a turned angle correction valueδFB* according to deviationΔγof an actual yaw rateγand a target yaw rateγ*. A target turned angleδ* is determined using a turned angle setting valueδFF* and a turned angle correction valueδFB* gain-adjusted by gain adjustment parts 41, 42. Gain of target reaction force torque Tm* is adjusted by a gain adjustment part 43. During the vehicle behavior stabilization control, when the turned angle correction valueδFB* is a predetermined value or less, a gain control part 40 raises the gain relative to the turned angle setting valueδFF*, descends the gain relative to the turned angle correction valueδFB*, and descends the gain relative to the target reaction force torque Tm*.
