Application Number: JP,2023-068482

Category (FI): B62D6/00,B62D5/04

Stage: PROBLEM TO BE SOLVED: To achieve steering reaction torque having a proper hysteresis characteristic according to a distribution ratio of first reaction torque according to a steering angle of a steering wheel and second reaction torque according to an estimation value of rack axial force applied from a road surface to a steering rack in a vehicle steering device which applies steering reaction torque obtained by synthesizing the first reaction torque and the second reaction torque to the steering wheel.SOLUTION: A vehicle steering device 1 includes: a distribution ratio setting section 61 which sets a distribution ratio of first reaction torque and second reaction torque; a hysteresis compensation section 66 which sets correction torque having a hysteresis characteristic according to a steering state and a steering angle of a steering wheel 10 according to the distribution ratio; and target steering reaction torque arithmetic sections (64, 67, 68) which calculate target steering reaction torque by applying the correction torque to the synthetic reaction torque obtained by synthesizing the first reaction torque and the second reaction torque at the distribution ratio.SELECTED DRAWING: Figure 6 (Grant)
